Party In Peru: New Critters Just Dropped
19 februari 2025 |
10 min
What happens when a team of scientists and local Awajún guides go on a 38-day trip into the Alto Mayo region of Peru? Over 2000 species are identified, of course! Tucked in this lush landscape where the Amazon basin meets the Andes mountains, were 27 species of animals previously unknown to science. It makes us wonder, what else is out there that the scientific community hasn't seen? And who already knows about it?

When AI Cannibalizes Its Data
18 februari 2025 |
13 min
Asked ChatGPT anything lately? Talked with a customer service chatbot? Read the results of Google's "AI Overviews" summary feature? If you've used the Internet lately, chances are, you've consumed content created by a large language model. These models, like DeepSeek-R1 or OpenAI's ChatGPT, are kind of like the predictive text feature in your phone on steroids. In order for them to "learn" how to write, the models are trained on millions of examples of human-written text. Thanks in part to these same large language models, a lot of content on the Internet today is written by generative AI. That means that AI models trained nowadays may be consuming their own synthetic content ... and suffering the consequences.

Could This Particle 'Clean Up' A Cosmic Mystery?
17 februari 2025 |
14 min
Physics has a bit of a messy problem: There's matter missing in our universe. Something is there that we can't see but can detect! What could this mysterious substance be? A lot of astronomers are searching for the answer. And some, like theoretical particle physicist Chanda Prescod-Weinstein, think a hypothetical particle called the axion may make this problem a little ... tidier.
That's right: hypothetical. Scientists have never seen one, and don't know if they exist. So today, we point our cosmic magnifying glasses towards the axion and ask how scientists could find one — and if it could be the neat solution physicists have been searching for.

Lessons in Love From Voles
14 februari 2025 |
11 min
For years, scientists have known that oxytocin is important in facilitating the feeling of love in humans. How do they know? Prairie voles. For years, scientists have relied on the cuddly rodents to help us humans understand how this protein works in our brains. But within the past few years, research has complicated that understanding, prompting the question: Can love prevail without the "love" hormone? (encore)

Stopping A Deadly Disease On Apache Lands
12 februari 2025 |
14 min
Rocky Mountain Spotted Fever is one of the deadliest tickborne diseases in the United States, often killing people within about a week if left untreated. At one point, the San Carlos Apache Reservation had rates of infection 150 times the national average. But now, they've achieved a huge milestone — no deaths from the disease in at least five years. NPR science correspondent Pien Huang and producer Megan Lim visited the reservation to see the program that led to their success.

What Happens Inside A Top-Secret U.S. Nuclear Facility?
11 februari 2025 |
14 min
The U.S. tested nuclear weapons until the early 1990s. Since then, scientists have been using supercomputers and experiments to simulate nuclear test detonations, without detonating any nukes. But there are signs the world's nuclear powers may be readying to test again: Russia, China and the U.S. are all upgrading their nuclear test sites.
NPR science correspondent Geoff Brumfiel was among a small group of journalists allowed to tour an underground laboratory where this research happens.

The Dangers Of Mirror Cell Research
10 februari 2025 |
13 min
For people with two hands, one is usually dominant. On a molecular level, life takes this to the extreme. All of the DNA in earthly living things twists to the right, whereas the protein building blocks favor a kind of left-handed chemistry. But in recent years, scientists have worked toward a kind of mirror version of life. The technology to make mirror life likely won't exist for at least a decade. Still, a group of concerned scientists published a 299-page technical report calling for a stop to the science. New York Times science columnist Carl Zimmer explains how a mirror microbe could wreak havoc on life on Earth in the future.
Check out the full technical report and Carl's full article.

Why Black Holes Are More Than They Seem
4 februari 2025 |
13 min
Black holes are notorious for gobbling up, well, everything. They're icons of destruction, ruthless voids, ambivalent abysses from which nothing can return — at least, according to pop culture. But black holes have another side: Astrophysicists have seen powerful jets, sometimes millions of light-years long, shooting out of supermassive black holes – including the one at the center of our own galaxy. So today, we're getting to know the other side of black holes, and the powerful role they may play in creating and shaping the cosmos.

Not All Nature Comebacks Are Equal
3 februari 2025 |
12 min
Ecologist Gergana Daskalova moved back to the small Bulgarian town of her childhood. It's a place many people have abandoned — and that's the very reason she returned. At the same time as land is being cleared around the world to make room for agriculture, elsewhere farmland is being abandoned for nature to reclaim. But what happens when people let the land return to nature? This episode, science reporter Dan Charles explains why abandoned land has conservationists and researchers asking: If we love nature, do we tend it or set it free?

Farts To The Rescue
29 januari 2025 |
14 min
Farts are funny and sometimes smelly. But are they a legitimate topic of research?
More than 40% of people worldwide are estimated to suffer from some kind of functional gut disorder — from acid reflux, heartburn, indigestion, constipation and irritable bowel syndrome to inflammatory bowel disease. So, yes, freelance science writer Claire Ainsworth thinks so. Claire speaks with Emily about two teams of scientists studying intestinal gases, who she profiled in a recent New Scientist article — and why understanding people's gut microbiome through a fart-shaped window may help treat these conditions at the source.

The Latest On Bird Flu
28 januari 2025 |
13 min
Bird flu, or avian influenza, is spreading among livestock and other mammals in the United States, raising concerns that another pandemic may be looming. Last month, California declared a state of emergency due to rising cases in dairy cattle, and there have been over 65 human cases in the U.S. during this outbreak. While cases have been largely mild and risk to the public is still considered low, scientists warn it could evolve and become more dangerous.

Where Are We In The Quest To Find Alien Life?
22 januari 2025 |
12 min
Around the turn of the century, 3.8 million people banded together in a real-time search for aliens — with screensavers. It was a big moment in a century-long concerted search for extraterrestrial intelligence. So far, alien life hasn't been found. But for people like astronomer James Davenport, that doesn't mean the hunt is worthless — or should be given up.
No, according to James, the search is only getting more exciting as new technology opens up a whole new landscape of possibilities. So today on the show: The evolving hunt for alien life.

How Will Future Forests Survive Climate Change?
21 januari 2025 |
14 min
Forests are the lungs of our planet. Not only do they absorb carbon dioxide and create oxygen, they also regulate temperature, absorb rainwater to help prevent flooding, and provide critical habitat for the majority of the world's land-based plant and animal species.
But due to land conversion for agriculture and road construction, timber harvesting, and increasing wildfires, the trees that make up our forests are increasingly endangered. That's why we need reforestation: replanting new forests to replace the old ones.
For the past century, the United States Forest Service has helped to replant new forests and manage existing ones. But as scientists face the ongoing threat of climate change, they're developing new strategies... including one that tries to literally predict the future.

The Science Behind The FDA Ban On Food Dye Red No. 3
20 januari 2025 |
10 min
On Wednesday, the Food and Drug Administration announced it is banning the dye called Red No. 3, a food dye additive in many processed foods, like sodas, sweets and snacks. Recently, it and other dyes were linked to behavior issues in children. But high levels of Red No. 3 were linked to cancer in rats decades ago. So why is the ban happening now?
Senior editor and science desk correspondent Maria Godoy answers our questions about Red No. 3 and other dyes that may replace it. Plus, how should parents think about feeding their kids products that may contain Red No. 3 before the ban takes affect.

All Of Life Has A Common Ancestor. What Was LUCA?
17 januari 2025 |
13 min
Imagine the tree of life. The tip of every branch represents one species, and if you follow any two branches back through time, you'll hit an intersection. If you keep going back in time, you'll eventually find the common ancestor for all of life. That ancestor is called LUCA, the last universal common ancestor, and there is no fossil record to tell us what it looked like.
Luckily, we have Jonathan Lambert. He's a science correspondent for NPR and today he's talking all things LUCA: What we think this single-celled organism may have looked like, when it lived and why a recent study suggests it could be older and more complex than scientists thought.

15 januari 2025 |
13 min
When you picture a dinosaur, what does it look like? For Jingmai O'Connor, paleobiologist and associate curator of reptiles at the Field Museum of Chicago, the dinosaurs she studies look a lot more like birds.
"If you looked at an artist's reconstruction of something like Velociraptor or Microraptor ... you would see that it pretty much looks the same as a bird," Jingmai says. "In terms of the plumage, the soft tissues covering the body, it would have looked very, very birdlike."
In this episode, Short Wave delves into the dinosaur-avian connection. Which dinosaurs had feathers? Were they using them to fly? And once and for all – what are those ancient dinosaurs' relationship to birds today?

Bone Marrow Cells: Key To Vaccine Longevity?
14 januari 2025 |
9 min
The COVID-19 mRNA vaccine generates enough of an antibody response to protect against severe disease for six months. But other vaccines offer years-long — even lifelong — immunity, such as the measles or yellow fever vaccines. Is there a way for scientists to tell how long a person's immunity will last? A team at Stanford Medicine might have found a way to do just that — with the help of some of the cells found in our bone marrow.

The Science Behind Wildfire Smoke
14 januari 2025 |
14 min
Air quality in the Los Angeles region has plummeted due to smoke from the ongoing wildfires. With all that smoke comes possible risks to human health. So what actually is smoke and why is it so harmful? Jessica Gilman, an atmospheric chemist with the National Oceanic and Atmospheric Administration, explains what smoke is made of, how it behaves in the atmosphere and smoke's role in climate change. Plus, tips for how to lessen your exposure.

What Are California's Santa Ana Winds?
10 januari 2025 |
10 min
Over 29,000 acres in the greater Los Angeles area are on fire right now. The fires emerged after the Santa Ana winds swept into the Los Angeles area Tuesday. The largest is the Palisades fire, which is quickly burning through the Pacific Palisades and Malibu communities. It's one of four ongoing critical fires — only one of which is partially contained. Ahead of the windy week, a Red Flag Warning was issued for an increased fire risk due to the strong winds, low humidity and higher temperature. Today, we dig into the Santa Ana winds: What they are and how they combined with other factors to create conditions for the most destructive fire in Los Angeles' history.

Fluoride: Fact vs. Fiction
8 januari 2025 |
12 min
Fluoridating the public water supply has been common practice for nearly 80 years in the U.S. It's an acclaimed public health intervention that helps prevent cavities. For just as long, some have raised concerns about the practice that can veer from evidence-based to unsubstantiated conspiracy. An analysis by government researchers, published Monday in JAMA Pediatrics, is adding to the debate. The research found that exposing babies and kids to high levels of fluoride might be associated with neurodevelopmental harm. Frankly, it's a lot to digest — so we invited health correspondent Pien Huang onto the show to wade through the debate.

How Two Veterans Developed The Same Rare Brain Condition
7 januari 2025 |
12 min
Some weapons used by the U.S. military are so powerful they can pose a threat to the people who fire them. Today, we meet two Marines, William Wilcox and Michael Lozano, who spent years firing missiles and rockets, then developed the same rare brain condition: arteriovenous malformation, or AVM. The condition sends high pressure blood from a tangle of abnormal blood vessels directly into fragile veins, which can leak or burst. Most AVMs are caused by genetic changes that affect the growth of blood vessels, so the connection between weapon blasts and AVM isn't always immediately clear. But NPR's brain correspondent Jon Hamilton reports that recent research suggests that blast waves can alter genes in the brain — and that the evidence is even stronger for less extreme blood vessel changes.

The Dubious World's Largest Snowflake Record
3 januari 2025 |
11 min
(encore) Snowflakes. These intricate, whimsical crystals are a staple of magical wintry scenes, but how big can they really get? Well, according to the Guinness World Record keepers, the "largest snowflake" ever recorded was a whopping 15 inches in diameter. It was spotted near Missoula, Montana in 1887. But Kenneth Libbrecht, a physicist at Caltech, has long been skeptical of that record. So he set out to find what makes a snowflake a snowflake and whether that 1887 record is scientifically possible. You can read more about what he discovered here.

The Trouble With Zero
1 januari 2025 |
12 min
Happy New Year, Short Wavers! What better time to contemplate the conundrum that is zero than this, the reset of the year? Zero is a fairly new concept in human history and even more recent as a number. It wasn't until around the 7th century that zero was being used as a number. That's when it showed up in the records of Indian mathematicians. Since then, zero has, at times, been met with some fear — at one point, the city of Florence, Italy banned the number.
Today, scientists seek to understand how much humans truly comprehend zero — and why it seems to be different from other numbers. That's how we ended up talking to science writer Yasemin Saplakoglu about the neuroscience of this number that means nothing.
Read more of Yasemin's reporting on zero for Quanta Magazine. Plus, check out our episode on why big numbers break our brains.

Bird Backpacks Could Help This Parrot Bounce Back
30 december 2024 |
14 min
The thick-billed parrot is the only surviving parrot species native to the United States. These brightly colored birds once roamed across the American Southwest and as far south as Venezuela — but today, the only wild population remaining lives high in the forests of Mexico's Sierra Madre mountains.
For years, conservation organizations like OVIS (Organización Vida Silvestre) and the San Diego Zoo Wildlife Alliance have been working on a multi-faceted conservation project to save these birds. Host Regina G. Barber and producer Rachel Carlson dive into the details of that project — and how tiny "bird backpacks" are helping to make it all happen.

Towana Looney became the first living person in the world to get a kidney from a new kind of genetically modified pig last month. Health correspondent Rob Stein got exclusive access to be in the operating room.
Towana is a 53-year-old grandmother from Gadsden, Ala. She's been on dialysis for four hours a day, three days a week since 2016. Her immune system would reject a human kidney. So the Food and Drug Administration made an exception to its usual clinical study requirements to allow Looney this new kind of pig kidney. But the procedure is controversial.

AI uses a lot of power. Some of the next generation data centers may use as much power as one million U.S. households. Technology companies like Microsoft, Google, Amazon and Meta hope nuclear power will offer a climate solution for this energy use. Nuclear power plants can deliver hundreds of megawatts of power without producing greenhouse gas emissions. But some long-time watchers of the nuclear industry are skeptical that it's the right investment for big tech companies to make.

The next four years may be challenging for foreign-born scientists who want to work in the United States. Foreign-born workers account for about half of the doctoral-level scientists and engineers working in the U.S., but the incoming Trump administration wants to make it harder for them to get H-1B visas. Some scientists worry a scarcity of H-1B visas may prompt top foreign researchers to work in other countries.

The Ambitious Quest To Genetically Map All Known Vertebrates
4 december 2024 |
15 min
The Vertebrate Genomes Project: It's an ambitious effort by an international group of scientists to create a "Genome Ark" by sequencing the genomes of about 70,000 animal species. The hope is that through all of this gene sequencing, scientists will be able to answer some basic but important questions like: What makes a bird, well, a bird? What makes a mammal a mammal? Plus, with so many species on the verge of extinction, can scientists record their genetic information before they go extinct – or better yet, maybe help save the population from going extinct? Guest host Jon Hamilton, one of our favorite science correspondents, talks to Erich Jarvis, the chair of this project, to learn what this ark of animal genomes could mean for our future – and why a platypus qualified for early boarding.

These Rats Can Drive. What's Happening In Their Brains?
3 december 2024 |
15 min
In neuroscientist Kelly Lambert's lab at the University of Richmond, rats hop into cars, rev their engines and skid across the floor of an arena. Researchers taught these tiny rodents to drive — and turns out, they really like it. But why?
Host Regina G. Barber talks with Kelly about her driving rats, and what they tell us about anticipation, neuroplasticity, and decision making. Plus, why optimism might be good for rats, and for humans too.

Why Your Brain Loves Sales
2 december 2024 |
14 min
This Cyber Monday, a meditation on holiday sales. A quick trip to pick up presents can turn into an hours-long shopping spree thanks to all the ways stores use research from fields like consumer neuroscience and neuromarketing to entice you. Retailers create urgency and scarcity to push you to give into the emotional part of your brain, motivated by the release of dopamine.
But with the help of NPR business correspondent Alina Selyukh, we get into the psychology of sales and discounts: Why it's SO hard to resist the tricks stores use — and some tips to outsmart them.

This Hazelnut May Help The Land Back Movement In Canada
29 november 2024 |
10 min
Beaked hazelnuts are a wild food native to North America. Indigenous peoples in British Columbia have passed down stories of these hazelnuts as a vital food source their ancestors planted and cultivated. These stories motivated Chelsea Geralda Armstrong of Simon Fraser University to look more deeply at the genetics of the beaked hazelnut and determine just how widely it was cultivated. Indigenous rights attorney Jack Woodward hopes research like this can make a difference in the Land Back movement, providing evidence that land once considered wilderness by European settler colonists was actually being carefully managed by tribes.

This COP29, It's All About The Numbers
27 november 2024 |
14 min
This year's United Nations climate talks, COP29, wrapped Saturday. Throughout the talks, it was all about the numbers. With the help of NPR climate reporters Julia Simon and Alejandra Borunda, we home in on two. First, $300 billion. That's the amount of money wealthy countries agreed to give developing countries to help them adapt to climate change and reduce pollution. Second, 1.5C. That's a warming limit countries agreed to try not to breach, but that is creeping closer every year.

How Do You Preserve An Endangered Language?
26 november 2024 |
13 min
By the end of the century, more than 40% of the world's estimated 7,000 languages are in danger of disappearing. Those include indigenous languages in the Amazon. The United Nations also estimates that an Indigenous language dies every two weeks. Today, we focus on two endangered languages spoken in the Vaupés region of northwest Amazonia: Desano and Siriano. Linguist Wilson de Lima Silva at the University of Arizona has been working with the community for a decade in an effort to document the language for future generations.

Are Starship Launches Trashing Texas?
22 november 2024 |
14 min
SpaceX's Starship rocket took off again Tuesday for its sixth test flight. Crowds, including President-elect Donald Trump, gathered at the launch site in Texas to watch it fly part way around the world to the Indian Ocean.
Starship – the largest rocket ever built – is the dream of Elon Musk, who hopes to make humans a multiplanetary species. But building the rocket is having a real impact on Earth. The launch site is located in the middle of one of Texas' largest wildlife sanctuaries and environmentalists say every launch is causing damage.
Plus, how government regulation of launches may change in a second Trump administration.

The Mystery of the Dead Coho Salmon
20 november 2024 |
12 min
For decades, Coho salmon were turning up dead in urban streams the Pacific Northwest. The salmon would stop swimming straight, and then die before they had a chance to spawn. Researchers worried that unless they figured out the cause, the species would eventually go extinct. Enter a formidable crew of biologists, modelers, community scientists, environmental chemists. After eventually ruling out the obvious suspects — things like temperature, oxygen levels and known toxins — researchers eventually zeroed in on a prime suspect: chemicals in tires. But the question remained: Which one?

How To Have Hard Conversations
19 november 2024 |
15 min
Many people are gearing up for holiday conversations with loved ones who may disagree with them — on everything from politics to religion and lifestyle choices. As the conversations unfold, these divisions are visible in our brains too. These conversations can get personal and come to a halt fast. But today on the show we get into research in neuroscience and psychology showing that as much as we disagree, there are ways to bridge these divides – and people who are actively using these strategies in their daily lives.

As global warming continues and space technology improves, there is more and more talk about the growing possibility of a sci-fi future in which humans become a multiplanetary species. Specifically, that we could live on Mars. Biologist Kelly Weinersmith and cartoonist Zach Weinersmith have spent the last four years researching what this would look like if we did this anytime soon. In their new book A City On Mars, they get into all sorts of questions: How would we have babies in space? How would we have enough food? They join host Regina G. Barber and explain why it might be best to stay on Earth.
Kelly and Zach Weinersmith's book A City On Mars is out now.

Elections Are One Big Math Problem
5 november 2024 |
16 min
It's Election Day in the United States. Across the nation, millions of ballots are being cast. But what would happen if the rules of our electoral system were changed? Certain states are about to find out. This year, several places have alternative voting systems up for consideration on their ballots, and those systems could set an example for voting reform throughout the rest of the country. Short Wave producer Hannah Chinn and host Emily Kwong dive into three voting methods that are representative of those systems: Where they've been implemented, how they work, and what they might mean for elections in the future.

Did Life Start In Hydrothermal Vents?
4 november 2024 |
14 min
How did life start on Earth? The answer is a big scientific mystery scientists are actively investigating. After talking with many scientists, host Regina G. Barber found that an abundance of water on Earth is most likely key, in some way, to the origin of life — specifically, in either deep sea hydrothermal vents or in tide pools. It's for this reason some scientists are also exploring the potential for life in so-called "water worlds" elsewhere in the solar system, like some of the moons of Jupiter and Saturn. This episode, Regina digs into two water-related hypotheses for the origin on life on Earth — and what that might mean for possible alien life.

A Brand New Kind of Schizophrenia Treatment
23 oktober 2024 |
12 min
For the past 70 years, schizophrenia treatments all targeted the same chemical: dopamine. While that works for some, it causes brutal side effects for others. An antipsychotic drug approved last month by the FDA changes that. It triggers muscarinic receptors instead of dopamine receptors. The drug is the result of a chance scientific finding ... from a study that wasn't even focused on schizophrenia. Host Emily Kwong and NPR pharmaceutical correspondent Sydney Lupkin dive into where the drug originated, how it works and what it might shift for people with schizophrenia.

Every American red wolf alive right now is descended from only 14 canids. In the 1970s, humans drove the red wolf to the brink of extinction. Because of that, red wolves today have low genetic diversity. But what if we could recover that diversity ... using "ghost genes"?
That's right, today's episode is a ghost story. Along the way, we get into gene dictionaries, the possibilities of poo and how a photo of a common Texas coyote started it all.

What The Heck Is A Rock Glacier?
11 oktober 2024 |
13 min
Even though there are more than 10,000 rock glaciers in the western United States, most people would look at one without knowing it. Unlike the snowy glaciers we're more familiar with, rock glaciers are under-researched and hiding in plain sight. But inside these glaciers covered with rocks is a little bit of climate hope.

Anxious? Try Watching A Scary Movie
9 oktober 2024 |
14 min
In human history, fear kept us safe when running from predators and anxiety kept us from going back to that lion-infested area. But what happens when these feelings get out of hand in humans today? And why do some of us crave that feeling from scary movies or haunted houses? For answers, we turn to Arash Javanbakht, a psychiatrist from Wayne State University. He likes studying fear so much, he wrote a whole book called Afraid. This episode, he gets into the difference between fear and anxiety, many of the reasons people feel afraid and why things like scary movies could even be therapeutic.

How Do You Spot A Liar?
8 oktober 2024 |
15 min
For over a century, we've been inventing technology to catch liars in the act. To this end, the polygraph was invented and became wildly popular in the mid-20th century. Then, there was an era of "micro-expression training," which claimed person could be caught lying through a skilled analysis of their face. Now, there's talk of using artificial intelligence to analyze the human voice.
But do any of these methods even work? And if not ... what are the risks? Emily and Gina investigates how deception research has changed and why it matters.

Fruit fly brains are smaller than a poppy seed, but that doesn't mean they aren't complex. For the first time, researchers have published a complete diagram of 50 million connections in an adult fruit flies brain. The journal Nature simultaneously published nine papers related to this new brain map. Until now, only a roundworm and a fruit fly larva had been mapped in this way.

What Lightning And Black Holes Have In Common
4 oktober 2024 |
7 min
Lightning: It happens all the time, and yet the exact details of how it's made has long eluded scientists. That is, until now. New research out this week in the journal Nature holds new insights into the precursor to lightning. To figure it out, researchers flew a NASA ER-2 – essentially the research version of a spy plane – over several tropical thunderstorms. What they found: The same high energy radiation is found in places like neutron stars and around black holes.

Do NYC Birds Hold The Clues To The Next Pandemic?
30 september 2024 |
11 min
Most viruses that become epidemics in humans begin in other animals. It's how scientists suspect COVID-19 emerged. And now, less than five years after the start of the pandemic, some scientists are concerned about another disease that could do something similar: bird flu, or H5N1. Over the past year, the virus has spilled into cows and other animals — even infecting some people working closely with the animals. Some scientists hope to build a more resilient public health system by finding ways to detect and to track viruses as they spread in animals.
One team in New York City is doing this by tapping high school students from underrepresented backgrounds. Together, they create a more equitable field of biologists while they also sniff out what could be the next pandemic.
This story was produced with support from the Education Writers Association Reporting Fellowship program.

Hurricane Helene Is Here And Powerful
27 september 2024 |

Governors across the southeastern United States have declared statewide states of emergency as Hurricane Helene continues its ascent. After forming in the northwestern Caribbean Sea Tuesday, Helene escalated from a tropical storm, then to a cyclone, and finally to a Category 4 hurricane by the time it made landfall late Thursday night. We talk to hurricane climatologist Jill Trepanier about how a storm tropical storm system rapidly intensifies into a major hurricane, the impact of a changing climate on future storms — and why the devastation doesn't stop at the shore.

The Reality Of OCD
25 september 2024 |
14 min
Around 2% of the global population struggles with obsessive compulsive disorder, or OCD. That's roughly 163 million people who go through cycles of obsessions – unwanted intrusive thoughts, images or urges – and compulsions, or behaviors to decrease the distress caused by these thoughts. In movies and TV, characters with OCD are often depicted washing their hands or obsessing about symmetry. Dr. Carolyn Rodriguez says these are often symptoms of OCD, but they're not the only ways it manifests – and there's still a lot of basics we have yet to understand. That's why Carolyn looks to include more populations in research and find new ways to treat OCD.

Solutions Week: Reducing The Food Waste Problem
13 september 2024 |
14 min
We close out Climate Solutions Week with a look at the final step in the food system: waste. Roughly 30-40% of all food produced globally gets thrown out — a huge problem when it comes to climate change. Shuggie's Trash Pie and Natural Wine has answers for what to do with all that waste – be it bruised fruit and wilted greens salad or meatballs made out of beef hearts. The San Francisco restaurant describes itself as a "climate-solutions restaurant" — and they're hoping you find these dishes appealing. Or at least, that you're willing to give them a try. Shuggie's is one of a growing number of eateries trying to address this problem.

Solutions Week: Reinventing Chocolate
11 september 2024 |
15 min
Climate change is contributing to erratic weather where cocoa beans are grown and threatening the global chocolate supply. Record rainfall last year led to fungal infections among cacao trees and dwindled supply of cocoa beans. Heat is also making it more difficult for cocoa beans to thrive. So, for day three of Climate Solutions Week, we look at one innovation in the food industry: chocolate substitutes.
As big chocolate manufacturers rush to stockpile cocoa beans, some companies like Planet A Foods are looking for a more sustainable solution: an alternative that looks like chocolate, tastes like chocolate and feels like chocolate... without chocolate.

Are You Overestimating The Algorithm?
3 september 2024 |

Humans hallucinate. Algorithms lie.
At least, that's one difference that Joy Buolamwini and Kyle Chayka want to make clear. When ChatGPT tells you that a book exists when it doesn't – or professes its undying love – that's often called a "hallucination." Buolamwini, a computer scientist, prefers to call it "spicy autocomplete." But not all algorithmic errors are as innocuous. So today's show, we get into: How do algorithms work? What are their impacts? And how can we speak up about changing them?
This is a shortened version of Joy and Kyle's live interview, moderated by Regina G. Barber, at this year's Library of Congress National Book Festival.

What's Missing From The Invasive Species Narrative?
28 augusti 2024 |
13 min
At first glance, the whole narrative of aquatic invasive species may seem straightforward: A bad non-native species comes into a new ecosystem and overruns good native species. But the truth? It's a little more complicated. To tear down everything we thought we knew about invasive species and construct a more nuanced picture, host Emily Kwong talks to experts Ian Pfingsten, who works on the United States Geological Survey's Nonindigenous Aquatic Species Database, and Nicholas Reo, a Canada Excellence Research Chair in Coastal Relationalities and Regeneration.

Preserving Your Humanity In The Age Of Robots
27 augusti 2024 |
14 min
Human beings are hardwired for social connection – so much so that we think of even the most basic objects as having feelings or experiences. (Yup, we're talking to you, Roomba owners!) Social robots add a layer to this. They're designed to make us feel like they're our friends. They can do things like care for children, the elderly or act as partners. But there's a darker side to them, too. They may encourage us to opt out of authentic, real-life connections, making us feel more isolated. Today on the show, host Regina G. Barber explores the duality of social robots with Eve Herold, author of the book Robots and the People Who Love Them.

Have you ever scrolled through a TikTok without finishing it? Switched between YouTube videos halfway through one or the other? Pressed "fast forward" on a Netflix episode that just wasn't holding your interest? That habit is called "digital switching" — and it might be causing the exact thing you're trying to avoid: boredom. Emily and Regina break that and more of the week's news down with the help of All Things Considered's Ailsa Chang.

What COVID Going Endemic Means For You
21 augusti 2024 |
13 min
U.S. health officials now say COVID-19 is an endemic disease. That means it's here to stay – circulating fairly regularly like the flu. Even though that changes how public health officials think about managing the virus, they say it doesn't mean being less cautious or vigilant during surges, like the current one this summer. COVID still poses significant risks for older individuals and those with underlying conditions — and anyone who gets COVID is at risk of developing long COVID.

The Power Of Braille Literacy
19 augusti 2024 |
13 min
For blind and low vision adults, the ability to read braille can be life-changing. Braille literacy is directly linked to higher rates of academic success and better employment outcomes for them. But there's a problem. The U.S. is facing a national shortage of qualified braille teachers and there's a lack of scientific research around braille overall. An interdisciplinary team led by linguist Robert Englebretson wants to change that.
Read some of the team's work here:
- Englebretson R, Holbrook MC, Fischer-Baum S. A position paper on researching braille in the cognitive sciences: decentering the sighted norm. Applied Psycholinguistics. 2023.
- Englebretson, R., Holbrook, M.C., Treiman, R. et al. The primacy of morphology in English braille spelling: an analysis of bridging contractions. Morphology. 2024.

Firing A Weapon Might Hurt Your Brain

Some weapons used by the United States military are so powerful, they can pose a threat to the people who fire them — even in training. When weapons are fired, an invisible blast wave travels through the brains of anyone nearby. Exposure to lots of these blasts over time — even low level ones — has been shown to cause brain health problems for service members.

How To Beat The Heat, Olympian-Style
14 augusti 2024 |
12 min
Over the next week, forecasts project extreme heat across much of the South, Midwest and parts of the West. So, this episode, health correspondent Pien Huang helps us take heat training cues from Olympians, many of whom spent weeks preparing for a sweltering Paris Olympics, by training in the heat to get their bodies used to hot, humid weather. But heat training is not just for competitive athletes. It's recommended for people in the military and those who work outdoors in hot weather — and it could even be useful for generally healthy members of the public. Plus, we get into some important caveats about who is best positioned to heat train — and why doing so doesn't minimize the problems of a warming climate.

What Is An Unfair Advantage In Sports?
10 augusti 2024 |
14 min
We at Short Wave have been following all things Olympics, from the medals and new records to the ugly accusations that two women boxers aren't really women. Last year, the boxers failed gender tests, according to the International Boxing Association. The IBA claims the women have a "hormonal imbalance" that gives them women an unfair advantage. The International Olympic Committee has condemned these claims and defended the boxers' right to compete in the women's category. But this Olympics is far from the first time the gender of athletes has been questioned.
NPR's Embedded podcast has a new series called Tested that gets into this history of sex testing in elite sports – in particular, track and field. In this excerpt, host Rose Eveleth digs deep on a big question: What constitutes an "unfair" advantage on the track?

The Toll Of Social Media On Mental Health
5 augusti 2024 |
13 min
Rates of depression and anxiety have risen among teens over the last decade. Amid this ongoing mental health crisis, the American Psychological Association issued guidelines for parents to increase protection for teens online. In this encore episode, NPR science correspondent Michaeleen Doucleff looks into the data on how that change has impacted the mental health of teenagers. In her reporting, she found that the seismic shift of smartphones and social media has re-defined how teens socialize, communicate and even sleep. In 2009, about half of teens said they were using social media daily, reported psychologist Jean Twenge. And by 2022, 95% of teens said they used some social media, and about a third said they use it constantly.

What Makes Simone Biles The GOAT, Scientifically
2 augusti 2024 |
13 min
Another Olympics, another set of stellar performances by the U.S. women's artistic gymnastics team. Thursday, the team won two medals in the women's all-around final: a gold for Simone Biles and a bronze for Sunisa Lee. The medals add to the team's overall count, which also includes a gold for the women's team final. Simone and Suni are expected to lead the team to more medals in the coming days. Each day the gymnasts compete, we are left to pick our jaws off the floor and wonder: How do they do that? So we called up one of our favorite science communicators, Frederic Bertley, to explain just that. He's the CEO of the Center of Science and Industry and our gymnastics physics guide for the day.

A previous version of this episode suggested that at the top of a gymnast's jump, they are moving with zero acceleration. In fact, there they have zero velocity, but still have the same acceleration. Also, gravity is constant as a person performs gymnastics tricks on Earth. A previous version of this episode also did not make clear that conservation of angular momentum happens as gymnasts move through the air in uneven bars — as opposed to when the gymnasts are on the bars themselves and the gymnasts are subject to additional forces.

What Chimpanzee Gestures Reveal About Human Communication

Chimpanzees are humans' closest living relatives. But does much of their communication resembles ours? According to a new study published earlier this week in the journal Current Biology, chimpanzees gesture back-and-forth in a similar way to how humans take turns speaking. The research presents an intriguing possibility that this style of communication may have evolved before humans split off from great apes, and tells researchers more about how turn-taking evolved.

Dancing Yeti Crabs, Morphing Cuttlefish, Other Stories From The Deep Sea
24 juli 2024 |
13 min
As a kid, Sabrina Imbler loved the ocean. They'd swim and snorkel, following around parrotfish in the water. Later, they tried to learn everything they could about the brightly-colored tropical fish – how some create a mucus cocoon at night to protect it from parasites, or how they help keep coral reefs healthy.
As they got older, their fascination with sea creatures only grew. Imbler released a collection of essays in 2022 called How Far The Light Reaches: A Life In Ten Sea Creatures. Each chapter focuses on a different marine species – from yeti crabs near hydrothermal vents in the deep sea to the morphing abilities of cuttlefish. Often, these creatures act as a mirror for Imbler to explore parts of their own identity.

How An Ambitious River Rerouting Plan Could Change India's Weather
19 juli 2024 |
14 min
More than a hundred years ago, a British engineer proposed linking two rivers in India to better irrigate the area and cheaply move goods. The link never happened, but the idea survived. Today, due to extreme flooding in some parts of the country mirrored by debilitating drought in others, India's National Water Development Agency plans to dig thirty links between rivers across the country. It's the largest project of its kind and will take decades to complete. But scientists are worried what moving that much water could do to the land, the people — and even the weather. Host Emily Kwong talks to journalist Sushmita Pathak about her recent story on the project.

The Magic — And Science — Of Synchronous Firefly Displays
17 juli 2024 |
14 min
Every year for two weeks between mid-May and mid-June, Congaree National Park in South Carolina is home to a fairy-tale-like display of flashing lights. These rhythmic performances happen all because of thousands of fireflies, flashing their belly lanterns at exactly the same time. According to the National Park Service, there are just three types of these synchronous fireflies in North America, making the experience all the more magical for the lucky visitors who get the chance to see them.
Firefly scientists and enthusiasts hope these displays in places like Congaree will inspire people to care about other kinds of fireflies, also known as lightning bugs, in the U.S., which are not as well-studied – or well-protected – as synchronous ones. Some community scientists are already taking on this mission with projects like the Firefly Atlas, where volunteers can help survey for fireflies and report sightings.

This Mysterious Energy Is Everywhere. Scientists Still Don't Know What It Is
16 juli 2024 |
15 min
The universe — everything in existence — is expanding every second! It's only been about a hundred years that humanity has known this, too — that most galaxies are traveling away from us and the universe is expanding. Just a few decades ago, in the late 1990s, scientists started to notice another peculiar thing: The expansion of the universe is speeding up over time. It's like an explosion where the debris gets faster instead of slowing down. The mysterious force pushing the universe outward faster and faster was named dark energy. Cosmologist Brian Nord joins host Regina G. Barber in a conversation that talks about what dark energy could be and what it implies about the end of our universe.

The Dubious Consent Question At The Heart Of The Human Genome Project
15 juli 2024 |
14 min
The Human Genome Project was a massive undertaking that took more than a decade and billions of dollars to complete. For it, scientists collected DNA samples from anonymous volunteers who were told the final project would be a mosaic of DNA. Instead, over two-thirds of the DNA comes from one person: RP11. No one ever told him. Science journalist Ashley Smart talks to host Emily Kwong about his recent investigation into the decision to make RP11 the major donor — and why unearthing this history matters to genetics today.

Teens Are Following Skincare Trends On TikTok. Some Dermatologists Are Wary
12 juli 2024 |
9 min
TikTok is fuel for many trends, including a skin care craze among teens, pre-teens — okay, and us. The "glass skin" trend calls for a multi-step routine, often involving pricey products. It's all in pursuit of dewy, seemingly poreless, glowing complexion – like glass. But some dermatologists say these attempts can backfire, irritating, burning and even peeling sensitive pre-teen skin. As teens and tweens have become major consumers of skin care products, dermatologists are seeing more of these cases and are cautioning against these elaborate routines.

Some ants herd aphids. Some farm fungi. And now, scientists have realized that when an ant injures its leg, it sometimes will turn to a buddy to perform a lifesaving limb amputation. Not only that — some ants have probably been amputating limbs longer than humans! Today, thanks to the reporting of ant enthusiast and science correspondent Nell Greenfieldboyce, we behold the medical prowess of the ant.

The Invisible Substance That Structures Our Universe
9 juli 2024 |
14 min
The universe is so much bigger than what people can see. Visible matter — the ground, the Sun, the screen you're reading this on — makes up only about 4 or 5 percent of our known universe. Dark matter makes up much more of the universe. It's all around us even though we can't see it. So what is it? What's it made out of? How do we even know it exists? Host Emily Kwong and Rebecca Ramirez try to find out with the help of astrophysicist Priyamvada Natarajan.

Researchers Are Figuring Out How African Ancestry Can Affect Certain Brain Disorders
3 juli 2024 |
13 min
Black Americans have been underrepresented in most genomic studies of neurological disorders. As a result, scientists don't know much about whether African ancestry affects a person's risk for these disorders or their response to a particular treatment. To help close this gap, the Lieber Institute for Brain Development, African American community leaders in Baltimore, and researchers from Duke University and Morgan State University created the African Ancestry Neuroscience Research Initiative in 2019. The team found that genes associated with African ancestry appear to affect certain brain cells in ways that could increase the risk of Alzheimer's disease and stroke.

Move Over Norse Mythology, There's A New Loki In Town — A Dinosaur
28 juni 2024 |
9 min
A brand new species of ceratops, or horned dinosaur, was recently discovered in northern Montana. The dinosaur is called Lokiceratops rangiformis, after the Norse god Loki, and is believed to have lived roughly eighty million years ago. The bones of the plant-eating dinosaur were found on private land in an area well known for its large amount of fossils, and at first, researchers thought the bones belonged to another species of dinosaur!

Humans are hardwired to see faces — even in inanimate objects. We have a lima bean-shaped part of our brains dedicated to facial recognition. But this process isn't always straightforward. Science journalist Sadie Dingfelder is one of 10 million Americans who are face blind, or struggle to recognize the faces of people they know. In her new book, Do I Know You? she dives into this, as well as the science of memory and imagination.

Some Stars Explode As They Die. We Look At Their Life Cycle
25 juni 2024 |
15 min
This summer, scientists have their eyes and telescopes trained on the small constellation system T Coronae Borealis. They think it will explode as part of a periodic nova — a once-in-a-lifetime event according to NASA scientists. And so, with the help of astrophysicist Sarafina El-Badry Nance, we continue our journey farther and deeper into spacetime with a look at the stars: How they're born and how they die. Sarafina has always been drawn to one particular star: Betelgeuse, a red supergiant in the shoulder of the constellation Orion that is nearing the end of its life. What stages of life did Betelgeuse — or any star — go through before it reached this moment?

Earth Is More Than A Planet With Life On It. It's A "Living Planet"
24 juni 2024 |
14 min
About ten years ago, science writer Ferris Jabr started contemplating Earth as a living planet rather than a planet with life on it. It began when he learned that the Amazon rainforest doesn't simply receive the rain that defines it; rather, it helps generate that rain. The Amazon does that by launching bits of biological confetti into the atmosphere that, in turn, seed clouds. After learning this, he began looking for other ways life changes its environment. That led to his new book Becoming Earth: How Our Planet Came to Life. He talks to host Regina G. Barber about examples of life transforming the planet — from changing the color of the sky to altering the weather.

Pluto Isn't A Planet — But It Gives Us Clues For How The Solar System Formed
18 juni 2024 |
14 min
Pluto hasn't been a planet for almost 20 years. In the early 2000s, scientists discovered several objects of a similar size to Pluto. So, during the summer of 2006, members of the International Astronomical Union convened in Prague to reconsider what counts as a planet in our solar system. IAU members decided that there were three criteria to be a planet — and Pluto didn't meet all of them.
But planetary scientist Wladymir Lyra says that even though it was downgraded to a dwarf planet, Pluto still has much to teach us about planet formation. This episode, he also lays out his case for Pluto — and many other objects in the solar system — to be considered a planet.

Wildlife trafficking is one of the largest and most profitable crime sectors in the world. The illegal trade estimated to be a multi-billion dollar industry. On a high level, that illegal trade causes problems for everything from global biodiversity to local economies and the balance of entire ecosystems. And on the immediate level, authorities are tasked with caring for confiscated animals and placing them in long-term care facilities.
One network launched last year by the U.S. Fish and Wildlife Service and the Association for Zoos and Aquariums hopes to help. And with wildlife trafficking surging globally, the organizations are now in talks to expand the program to other parts of the country.

Baobabs are sometimes called the "tree of life" with their thick trunks, crown of branches and flowers that only open at twilight. But theories about their geographic origin was divided among three places: the savannas of sub-Saharan Africa, the Kimberley region of western Australia and the dry forests of the island nation of Madagascar. To solve this mystery, a global research team led by scientists at the Wuhan Botanical Garden at the Chinese Academy of Sciences examined high-quality genomic data from all eight baobab species.

Scientists at the National Oceanic and Atmospheric Administration observed a cluster of sunspots on the surface of the sun this week. With them came solar flares that kicked off a severe geomagnetic storm. That storm is expected to last throughout the weekend as at least five coronal mass ejections — chunks of the sun — are flung out into space, towards Earth! NOAA uses a five point scale to rate these storms, and this weekend's storm is a G4. It's expected to produce auroras as far south as Alabama. To contextualize this storm, we are looking back at the largest solar storm on record: the Carrington Event.

How Autism Can Look Very Different, Even In Identical Twins
10 maj 2024 |
11 min
Sam and John Fetters, 19, are identical twins on different ends of the autism spectrum. Sam is a sophomore at Amherst College and runs marathons in his free time. John attends a school for people with special needs and loves to watch Sesame Street in his free time. Identical twins like Sam and John pose an important question for scientists: How can a disorder that is known to be highly genetic look so different in siblings who share the same genome?

'Stealing The Past': A Spat Between Twins Leads To A Theory Of Disputed Memories
6 maj 2024 |
13 min
It's not unusual for siblings to quibble over ownership of something — a cherished toy, a coveted seat in the car — or whose fault something is. If you're Mercedes Sheen, you not only spent your childhood squabbling with your sister over your memories, you then turn it into your research career. Mercedes studies disputed memories, where it's unclear who an event happened to. It turns out these memories can tell us a lot about people — they tend to be self-aggrandizing — and how the human brain remembers things.

Deer Are Expanding North. That Could Hurt Some Species Like Boreal Caribou
3 maj 2024 |
9 min
Wildlife ecologists have seen white-tailed deer expanding their range in North America over many decades. And since the early-2000s these deer have moved north into the boreal forests of western Canada. These forests are full of spruce and pine trees, sandy soil and freezing winters with lots of snow. They can be a harsh winter wonderland. And ecologists haven't known whether a warmer climate in these forests or human land development might be driving the deer north. A recent study tries to disentangle these factors – and finds that a warming climate seems to play the most significant role in the movement of deer.

The Mysterious "Great Attractor" Pulling Our Galaxy Off Course
1 maj 2024 |
13 min
No matter what you're doing right now – sitting, standing, walking – you're moving. First, because Earth is spinning around on its axis. This rotation is the reason we have days. Second, because Earth and other planets in our solar system are orbiting the sun. That's why we have years. Third, you're moving because the sun and the rest of our solar system is orbiting the center of the Milky Way galaxy at over 500,000 miles per hour. If all of that isn't nauseating enough, everything in the entire universe is expanding outward. All the time.
But in the 1970s, astrophysicists noticed something strange about our galactic neighborhood, or Local Group. The whole clump of neighboring galaxies was being pulled off course at over one million miles per hour, towards something we couldn't see — the "Great Attractor." This Great Attractor sits in the "Zone of Avoidance," an area of space that is blocked from view by the stars and gas of the Milky Way. Today on the show, host Regina G. Barber talks to astrophysicist Jorge Moreno about this mysterious phenomenon: What it might be and what will happen when we eventually reach it.

10 Years After Flint, The Fight To Replace Lead Pipes Continues
26 april 2024 |
13 min
Ten years ago, Flint, Mich. switched water sources to the Flint River. The lack of corrosion control in the pipes caused lead to leach into the water supply of tens of thousands of residents. Pediatrician Mona Hanna-Attisha recognized a public health crisis in the making and gathered data proving the negative health impact on Flint's young children. In doing so, she and community organizers in Flint sparked a national conversation about lead in the U.S. water system that persists today.
Today on the show, host Emily Kwong and science correspondent Pien Huang talk about the state of Flint and other cities with lead pipes. Efforts to replace these pipes hinge on proposed changes to the EPA's Lead and Copper Rule.

Beavers Can Help With Climate Change. So How Do We Get Along?
24 april 2024 |
14 min
NPR's Tom Dreisbach is back in the host chair for a day. This time, he reports on a story very close to home: The years-long battle his parents have been locked in with the local wild beaver population. Each night, the beavers would dam the culverts along the Dreisbachs' property, threatening to make their home inaccessible. Each morning, Tom's parents deconstructed those dams — until the annual winter freeze hit and left them all in a temporary stalemate.
As beaver populations have increased, so have these kinds of conflicts with people...like Tom's parents. But the solution may not be to chase away the beavers. They're a keystone species that scientists believe could play an important role in cleaning water supplies, creating healthy ecosystems and alleviating some of the effects of climate change. So, today, Tom calls up Jakob Shockey, the executive director of the non-profit Project Beaver. Jakob offers a bit of perspective to Tom and his parents, and the Dreisbachs contemplate what a peaceful coexistence with these furry neighbors might look like.

14 min
Roughly 196 million tons of fish were harvested in 2020, according to the Food and Agriculture Organization of the United Nations. The organization also notes that the number of overfished stocks worldwide has tripled in the last century. All of this overfishing has led to the decline of entire species, like Atlantic cod.
Enter the Monterey Bay Aquarium's Seafood Watch. It and other free guides give consumers an overview of the world of fish and seafood, helping people to figure out the most sustainable fish available to them. With the help of Life Kit's Clare Marie Schneider, we figure out how to make informed decisions about what we eating – whether that's at a restaurant or the local supermarket.

The Nightmarish Worm That Lived 25 Million Years Longer Than Researchers Thought
17 april 2024 |
13 min
500 million years ago, the world was a very different place. During this period of time, known as the Cambrian period, basically all life was in the water. The ocean was brimming with animals that looked pretty different from the ones we recognize today — including a group of predatory worms with a throat covered in teeth and spines.
Researchers thought these tiny terrors died out at the end of the Cambrian period. But a paper published recently in the journal Biology Letters showed examples of a new species of this worm in the fossil record 25 million years after scientists thought they'd vanished from the Earth. One of the authors of the paper, Karma Nanglu, tells us how this finding may change how scientists understand the boundaries of time.

What To Know About The New EPA Rule Limiting 'Forever Chemicals' In Tap Water
12 april 2024 |
13 min
Wednesday the Environmental Protection Agency announced new drinking water standards to limit people's exposure to some PFAS chemicals. For decades, PFAS have been used to waterproof and stain-proof a variety of consumer products. These "forever chemicals" in a host of products — everything from raincoats and the Teflon of nonstick pans to makeup to furniture and firefighting foam. Because PFAS take a very long time to break down, they can accumulate in humans and the environment. Now, a growing body of research is linking them to human health problems like serious illness, some cancers, lower fertility and liver damage. Science correspondent Pien Huang joins the show today to talk through this new EPA rule — what the threshold for safe levels of PFAS in tap water is, why the rule is happening now and how the federal standards will be implemented.
Read more of Pien's reporting on the EPA's first ever rule on PFAS in drinking water.

The Order Your Siblings Were Born In May Play A Role In Identity And Sexuality
10 april 2024 |
12 min
It's National Siblings Day! To mark the occasion, guest host Selena Simmons-Duffin is exploring a detail very personal to her: How the number of older brothers a person has can influence their sexuality. Scientific research on sexuality has a dark history, with long-lasting harmful effects on queer communities. Much of the early research has also been debunked over time. But not this "fraternal birth order effect." The fact that a person's likelihood of being gay increases with each older brother has been found all over the world – from Turkey to North America, Brazil, the Netherlands and beyond. Today, Selena gets into all the details: What this effect is, how it's been studied and what it can (and can't) explain about sexuality.

The "Barcodes" Powering These Tiny Songbirds' Memories May Also Help Human Memory
5 april 2024 |

Tiny, black-capped chickadees have big memories. They stash food in hundreds to thousands of locations in the wild – and then come back to these stashes when other food sources are low. Now, researchers at Columbia University's Zuckerman Institute think neural activity that works like a barcode may be to thank for this impressive feat — and that it might be a clue for how memories work across species.

Historic numbers of animals across the globe have become endangered or pushed to extinction. But some of these species sit in limbo — not definitively extinct yet missing from the scientific record. Rediscovering a "lost" species is not easy. It can require trips to remote areas and canvassing a large area in search of only a handful of animals. But new technology and stronger partnerships with local communities have helped these hidden, "uncharismatic" creatures come to light.

According to the CDC, about one in four adults has a fear of needles. Many of those people say the phobia started when they were kids. For some people, the fear of needles is strong enough that they avoid getting important treatments, vaccines or tests. That poses a serious problem for public health. Researchers have helped develop a five step plan to help prevent what they call "needless pain" for kids getting injections or their blood drawn. Guest host Tom Dreisbach talks with Dr. Stefan Friedrichsdorf of UCSF Benioff Children's Hospitals, who works with a team to implement the plan at his own hospital. Friedrichsdorf told us some of the most important research on eliminating pain has come from researchers in Canada. Learn more about their work here.

The Evolutionary Mystery Of Menopause ... In Whales
22 mars 2024 |
10 min
Across the animal kingdom, menopause is something of an evolutionary blip. We humans are one of the few animals to experience it. But Sam Ellis, a researcher in animal behavior, argues that this isn't so surprising. "The best way to propagate your genes is to get as many offspring as possible into the next generation," says Ellis. "The best way to do that is almost always to reproduce your whole life."
So how did menopause evolve? The answer may lie in whales. Ellis and his team at the University of Exeter recently published a study in the journal Nature that studies the evolution of menopause in the undersea animals most known for it. What they uncovered may even help explain menopause in humans.

Coming down from the buzz of the Oscars, we're taking a look at Christopher Nolan's award-winning film 'Oppenheimer.' It chronicles the life and legacy of J. Robert Oppenheimer, the first director of Los Alamos National Laboratory and the so-called "Father of the Atomic Bomb." The movie does not shy away from science — and neither do we. We talked to current scientists at Los Alamos about the past and present science of nuclear weapons like the atomic bomb.

The "Shocking" Tactic Electric Fish Use to Collectively Sense the World
8 mars 2024 |
9 min
Neuroscientist Nathan Sawtell has spent a lot of time studying the electric elephantnose fish. These fish send and decipher weak electric signals, which Sawtell hopes will eventually help neuroscientists better understand how the brain filters sensory information about the outside world. As Sawtell has studied these electric critters, he's had a lingering question: why do they always seem to organize themselves in a particular orientation. At first, he couldn't figure out why, but a new study released this week in Nature may have an answer: the fish are creating an electrical network larger than any field a single fish can muster alone, and providing collective knowledge about potential dangers in the surrounding water.

The Recent Glitch Threatening Voyager 1
6 mars 2024 |
12 min
The Voyager 1 space probe is the farthest human-made object in space. It launched in 1977 with a golden record on board that carried assorted sounds of our home planet: greetings in many different languages, dogs barking, and the sound of two people kissing, to name but a few examples. The idea with this record was that someday, Voyager 1 might be our emissary to alien life – an audible time capsule of Earth's beings. Since its launch, it also managed to complete missions to Jupiter and Saturn. In 2012, it crossed into interstellar space.
But a few months ago, the probe encountered a problem. "It's an elderly spacecraft," says NPR science correspondent Nell Greenfieldboyce, "and it had some kind of electronic stroke." Greenfieldboyce talks to Short Wave Host Regina G. Barber about the precarious status of Voyager 1 – the glitch threatening its mission, and the increasingly risky measures NASA is taking to try and restore it.

The Evolution Of Cancer Treatment
4 mars 2024 |
14 min
Recently, the US Food and Drug Administration approved a first-of-its-kind cancer therapy to treat aggresive forms of skin cancer. It has us thinking of the long history of cancer. One of the first recorded mentions of cancer appears in an ancient Egyptian text from around 3000 B.C. And although we now know much more about how cancer begins — as a series of mutations in someone's DNA — it's a disease people are still grappling with how to cure cancers today. This episode, cancer epidemiologist Mariana Stern talks about cancer history and treatment today — plus, why some people are more prone to certain cancers and why that might matter for curing them.

Is It Possible To Feed The World Sustainably?
28 februari 2024 |
11 min
According to the United Nations, about ten percent of the world is undernourished. It's a daunting statistic — unless your name is Hannah Ritchie. She's the data scientist behind the new book Not the End of the World: How We Can Be the First Generation to Build a Sustainable Planet. It's a seriously big thought experiment: How do we feed everyone on Earth sustainably? And because it's just as much an economically pressing question as it is a scientific one, Darian Woods of The Indicator from Planet Money joins us. With Hannah's help, Darian unpacks how to meet the needs of billions of people without destroying the planet.

In Light of The Alabama Court Ruling, A Look At The Science Of IVF
26 februari 2024 |
13 min
An Alabama Supreme Court ruling that frozen embryos can be considered "extrauterine children" under state law has major implications for how in vitro fertilization, commonly called IVF, is performed. Since the first successful in vitro fertilization pregnancy and live birth in 1978, nearly half a million babies have been born using IVF in the United States. Reproductive endocrinologist Amanda Adeleye explains the science behind IVF, the barriers to accessing it and her concerns about fertility treatment in the post-Roe landscape.

Didn't Get A Valentine's Love Song? These Skywalker Gibbons Sing Love Duets
23 februari 2024 |

In the green tree canopies of forested areas in Myanmar, you might wake up to the sounds of gibbons singing love songs. Gibbons start their day with passionate duets and, though these love songs may sound a little different than the ones in your playlists, they just helped researchers figure out that Myanmar has the largest population of an endangered gibbon species on Earth. They're called skywalker gibbons, and until recently, scientists thought there were fewer than 200 of them – all living in southwestern China.

When The Sun Erupts
21 februari 2024 |
12 min
We are at the height of the Sun's activity in its eleven year cycle, known to astronomers as the solar maximum. This means that over the next several months there's going to be a lot of solar activity. It's got us thinking back to 1859. That's when astronomer Richard Carrington was studying the Sun when he witnessed the most intense geomagnetic storm recorded in history. The storm, triggered by a giant solar flare, sent brilliant auroral displays across the globe causing electrical sparking and fires in telegraph stations. This encore episode, Regina talks to solar physicist Dr. Samaiyah Farid about what's now known as the Carrington event and about what may happen the next time a massive solar storm hits Earth.

The Life And Death Of A Woolly Mammoth
19 februari 2024 |
14 min
Lately, paleoecologist Audrey Rowe has been a bit preoccupied with a girl named Elma. That's because Elma is ... a woolly mammoth. And 14,000 years ago, when Elma was alive, her habitat in interior Alaska was rapidly changing. The Ice Age was coming to a close and human hunters were starting early settlements. Which leads to an intriguing question: Who, or what, killed her? In the search for answers, Audrey traces Elma's life and journey through — get this — a single tusk. Today, she shares her insights on what the mammoth extinction from thousands of years ago can teach us about megafauna extinctions today with guest host Nate Rott.

The U.N.'s First-Ever Analysis Of World's Migratory Species Just Dropped
16 februari 2024 |
13 min
Every year, billions of animals across the globe embark on journeys. They fly, crawl, walk or slither – often across thousands of miles of land or water – to find better food, more agreeable weather or a place to breed. Think monarch butterflies, penguins, wild Pacific salmon. These species are crucial to the world as we know it. But until this week, there has never been an official assessment of the world's migratory animals.
So today on the show, correspondent Nate Rott shares the first-ever report on state of the world's migratory animals – the threats facing them and what can be done to help.

The Shared History Of The Chinese And Gregorian Calendars
12 februari 2024 |
13 min
Happy Lunar New Year! According to the Chinese lunisolar calendar, the new year began Saturday. For many, like our host Regina G. Barber, this calendar and its cultural holidays can feel completely detached from the Gregorian calendar. Growing up, she associated the former with the Spring Festival and getting money in red envelopes from relatives, and the other with more American traditions. But the Chinese calendar has a deep, centuries-long shared history with the Gregorian calendar.
To learn more about this shared history, Gina talks to scientists and historians, who spill the tea about the science behind calendars, and how both calendars and the Chinese Lunar New Year celebration played a key role in the rise and fall of empires.

Clownfish Might Be Counting Their Potential Enemies' Stripes
9 februari 2024 |
9 min
At least, that's what a group of researchers at the Okinawa Institute of Science and Technology Graduate University thinks. The team recently published a study in the journal Experimental Biology suggesting that Amphiphrion ocellaris, or clown anemonefish, may be counting. Specifically, the authors think the fish may be looking at the number of vertical white stripes on each other as well as other anemonefish as a way to identify their own species. Not only that — the researchers think that the fish are noticing the minutiae of other anemonefish's looks because of some fishy marine geopolitics.

After 20 Years, This Scientist Uncovered The Physics Behind The Spiral Pass
7 februari 2024 |
12 min
If you've ever watched part of a professional football game, you've probably seen a tight spiral pass. Those perfect throws where the football leaves the player's hand and neatly spins as it arcs through the air.
But those passes? They seem to defy fundamental physics. And for a long time, scientists couldn't figure out exactly why — until experimental atomic physicist Tim Gay cracked the case just a few years ago. His answer comes after two decades of hobby research and more than a couple late night shouting matches with two other physicists over Zoom.
Today on Short Wave, host Regina G. Barber talks to Tim about this football mystery — and the physics behind the game.

Wolves Are Thriving In The Radioactive Chernobyl Exclusion Zone
5 februari 2024 |
14 min
In 1986 the Chernobyl nuclear power plant exploded, releasing radioactive material into northern Ukraine and Belarus. It was the most serious nuclear accident in history. Over one hundred thousand people were evacuated from the surrounding area. But local gray wolves never left — and their population has grown over the years. It's seven times denser than populations in protected lands elsewhere in Belarus. This fact has led scientists to wonder whether the wolves are genetically either resistant or resilient to cancer — or if the wolves are simply thriving because humans aren't interfering with them.
This episode, researchers Shane Campbell-Staton and Cara Love talk through what might be causing this population boom. Plus, why researchers in the field of human cancer are eager to collaborate with them.

13 min
Back in the day, many of us heard that the appendix is a vestigial organ — at best, a body part that lost its purpose all those many years ago. At worst, an unnecessary clinger-on to the human body that, when ruptured, could be life threatening. But what if that narrative is wrong?
Heather Smith became obsessed with the appendix after hers was removed at age 12. After years of anatomy research, she's found that the appendix is not, in fact, useless. Reporter Selena Simmons-Duffin is in the host chair today to get the scoop on all things appendix.

Murder, Mayhem At The Zoo: A Naked Mole Rat Succession War
31 januari 2024 |
15 min
An all-out "naked mole rat war" has broken out at Smithsonian's National Zoo, after the queen of the colony was mortally wounded by one of her own children. Short Wave's Pien Huang and Margaret Cirino visit the battleground – a series of deceptively calm-looking plexiglass enclosures at the Zoo's Small Mammal House. There, the typically harmonious, eusocial rodents are now fighting their siblings with their big front teeth to determine who will become the new queen. Pien and Marge talk with zookeeper Kenton Kerns about what led to this violent succession drama, the stress he feels in witnessing his first naked mole rat war and how he hopes it will resolve.

Choose Your Lightning Protection: Lasers, Rockets or Rods?
29 januari 2024 |
12 min
Every year, lightning is estimated to cause up to 24,000 deaths globally. It starts forest fires, burns buildings and crops, and causes disruptive power outages. The best, most practical technology available to deflect lightning is the simple lightning rod, created by Benjamin Franklin more than 250 years ago. But lightning rods protect only a very limited area proportional to their height. In today's encore episode, we explore why a group of European researchers are hoping the 21 century upgrade is a high-powered laser. Plus: Regina makes incremental progress on conquering her irrational fear of lightning.

Lessons on the limits of ecosystem restoration from the Everglades
27 januari 2024 |
16 min
When the U.S. government and state of Florida unveiled a new plan to save the Everglades in 2000, the sprawling blueprint to restore the wetlands became the largest hydrological restoration effort in the nation's history. Two decades later, only one project is complete, the effort is $15 billion over budget and the Everglades is still dying. The new podcast Bright Lit Place from WLRN and NPR heads into the swamp to meet its first inhabitants, the scientists who study it and the warring sides struggling to find a way out of the muck. Today, we hear an excerpt as environment reporter Jenny Staletovich tags along with wetlands ecologist Evelyn Gaiser to the remotest part of the swamp.

When Tiny, Invasive Ants Go Marching In...And Alter An Ecosystem
26 januari 2024 |
9 min
At the Ol Pejeta Conservancy, a wildlife preserve in central Kenya, lions and cheetahs mingle with zebras and elephants across many miles of savannah – grasslands with "whistling thorn" acacia trees dotting the landscape here and there. Twenty years ago, the savanna was littered with them. Then came invasive big-headed ants that killed native ants — and left the acacia trees vulnerable. Over time, elephants have knocked down many of the trees. That has altered the landscape — and the diets of other animals in the local food web.

Experiencing Racism May Physically Change Your Brain
24 januari 2024 |
14 min
Scientists know that Black people are at a greater risk for health problems like heart disease, diabetes and Alzheimer's disease than white people. A growing body of research shows that racism–in health systems and the effects of experiencing racial discrimination–contributes to these long-standing health disparities for Black communities. Now, some researchers are asking whether part of the explanation involves how racism changes the brain.
Today on the show, science correspondent Jon Hamilton speaks with Nate Harnett, an assistant professor of psychiatry at Harvard Medical School, and Negar Fani, a clinical neuroscientist at Emory University about how experiencing racism may change the brain.

At least one in four women — and a much smaller proportion of men — experiences intimate partner violence in their lifetime. For people in violent relationships, brain injuries are unfortunately common. But little is known about what exactly happens inside the brains of people dealing with domestic violence — and how these kinds of traumatic brain injuries may be different from those that come out of contact sports like football. Host Regina G.

Time is a concept so central to our daily lives. Yet, the closer scientists look at it, the more it seems to fall apart. Time ticks by differently at sea level than it does on a mountaintop. The universe's expansion slows time's passage. "And some scientists think time might not even be 'real' — or at least not fundamental," says NPR science correspondent Geoff Brumfiel. In this encore episode, Geoff joins Short Wave Scientist in Residence Regina G. Barber to bend our brains with his learnings about the true nature of time. Along the way, we visit the atomic clocks at the National Institute of Standards and Technology, consider distant exploding stars and parse the remains of subatomic collisions.

Preserving Our Humanity In The Age Of Robots
10 januari 2024 |
14 min
Human beings are hardwired for social connection – so much so that we think of even the most basic objects as having feelings or experiences. (Yup, we're talking to you, Roomba owners!) Social robots add a layer to this. They're designed to make us feel like they're our friends. They can do things like care for children, the elderly or act as partners. But there's a darker side to them, too. They may encourage us to opt out of authentic, real-life connections, making us feel more isolated.
Today on the show, host Regina G. Barber explores the duality of social robots with Eve Herold, author of the new book Robots and the People Who Love Them: Holding on to Our Humanity in an Age of Social Robots.

The Record For World's Largest Snowflake Might Not Count
8 januari 2024 |
11 min
A winter storm brought heavy rain and snow to parts of the East Coast this weekend, which got us thinking about snowflakes. Those intricate, whimsical crystals are a staple of magical wintry scenes, but how big can they really get? Well, according to the Guinness World Record keepers, the "largest snowflake" ever recorded was a whopping 15 inches in diameter. It was spotted near Missoula, Montana in 1887. But Kenneth Libbrecht, a physicist at Caltech, has long been skeptical of that record. So he set out to find what makes a snowflake a snowflake and whether that 1887 record is scientifically possible. You can read more about what he discovered here.

Snow Flies Pay An Arm And A Leg For Love
5 januari 2024 |
13 min
The winter is usually when insects die or go into a state of paused development, but for tiny specks on the white snow called snow flies, it's time to run around, find a lover and make baby snow flies. Neuroscientist John Tuthill has been studying these creatures since he first came across them in 2016. He's found that not only can they survive in the cold, but if one of their limbs starts to freeze, they can self-amputate and pop it right off. That buys the snow fly time to find a mate and make sweet, sweet snow fly love.

Asian Glow Might Have A Major Upside
1 januari 2024 |
14 min
Ever gotten a scarlet, hot face after drinking? Or know someone who has? Many people felt it as they ring in the New Year with champagne toasts. That's because this condition, commonly called "Asian flush" or "Asian glow," affects an estimated half a BILLION people, who can't break down aldehyde toxins that build up in their bodies. But what if there's a benefit to having Asian glow?
Katie Wu, a staff writer for The Atlantic, has looked into the research a theory as to why the condition might have been a powerful tool for some of our ancestors to survive disease.

Life Could Be Different ... And Maybe Better?
27 december 2023 |
13 min
Are people ever satisfied? Two social psychologists, Ethan Ludwin-Peery and Adam Mastroianni, fell down a research rabbit hole accidentally answering a version of this very question. After conducting several studies, the pair found that when asked how things could be different, people tend to give one kind of answer, regardless of how the question is asked or how good life felt when they were asked. Short Wave's Scientist in Residence Regina G. Barber digs into the research—and how it might reveal a fundamental law of psychology about human satisfaction. (encore)

Once A Satirical Conspiracy, Bird Drones Could Soon Be A Reality
21 december 2023 |
14 min
Millions of people in the U.S. are bird watchers. But a couple of years ago a satirical conspiracy theory gained popularity because of an absurd claim: That those birds were also watching people.
Now, rather than being the stuff of internet memes, some engineers are, in fact, trying to reverse engineer how birds fly to eventually take what they learn to create more efficient bird-like drones.
Today on the show, host Regina G. Barber talks to reporter Anil Oza about how scientists are using real birds to make fake ones.

Climate Talks Call For A Transition Away From Fossil Fuels. Is That Enough?
20 december 2023 |
14 min
For the first time in its history, the United Nations climate conference concluded with a call to transition away from fossil fuels. But not all of the nearly 200 countries present at the meeting, known as COP28, were happy with the final agreement. Critics of the agreement had instead called for a clear path towards phasing out fossil fuels and pointed out a "litany of loopholes" in the final text. This episode, we look at the tensions and breakthroughs of the conference — and how far behind we are in limiting the devastating impacts that could be on the way.

More Plant And Fungi Emojis, Please!
15 december 2023 |

A team of conservation biologists from Italy recently found that current emoji options are sorely lacking when it comes to life outside of vertebrates in the animal kingdom. Sure, there are multiple dog and cat options to choose from. But when it comes to fungi, for example, the choices are limited ... to one. The study was published this week in the journal iScience argues that our emoji lexicon is in dire need of some biodiversity – which could have a real impact on the way people communicate about conservation.

Malls are designed to overwhelm our brains. Add the stress of holiday shopping, and a quick trip to pick up presents could turn into an hours-long shopping spree thanks to all the ways stores use research from fields like consumer neuroscience and neuromarketing to entice you. Retailers create urgency and scarcity to push you to give into the emotional part of your brain, motivated by the release of dopamine.
But we've got your back! With the help of NPR business correspondent Alina Selyukh, we get into the psychology of sales and discounts: Why it's SO hard to resist the tricks stores use — and some tips to outsmart them.

How Glaciers Move — And Affect Sea Level Rise
11 december 2023 |
14 min
Glaciers like the ones in Greenland are melting due to climate change, causing global sea levels to rise. That we know. But these glaciers are also moving. What we don't know is just how these two processes – melting and movement – interact and ultimately impact how quickly sea levels will rise. This encore episode, Jessica Mejía, a postdoctoral researcher in glaciology at the University of Buffalo, explains what it's like to live on a glacier for a month and what her research could mean for coastal communities all over the world.

Don't Call It Dirt: The Surprising Science Of Soil
4 december 2023 |
12 min
It's easy to overlook the soil beneath our feet, or to think of it as just dirt to be cleaned up. But soil wraps the world in an envelope of life: It grows our food, regulates the climate and makes the planet habitable. "What stands between life and lifelessness on our planet Earth is this thin layer of soil that exists on the Earth's surface," says Asmeret Asefaw Berhe, a soil scientist at the University of California-Merced.
In honor of World Soil Day tomorrow, we're revisiting our conversation with Prof. Berhe, who is also serving as Director of the U. S. Dept. of Energy's Office of Science. She talks to Aaron about the hidden majesty of soil and why it's crucial to tackling the climate crisis.

The International Race To Create Human Eggs And Sperm In The Lab
29 november 2023 |
15 min
In which we meet the pioneers of one of the most exciting — and controversial — fields of biomedical research: in vitro gametogenesis, or IVG. The goal of IVG is to make unlimited supplies of what Hayashi calls "artificial" eggs and sperm from any cell in the human body. That could let anyone — older, infertile, single, gay, trans — have their own genetically related babies. As such, the field opens up a slew of ethical concerns.
But that isn't stopping researchers from pressing forward.
So, this episode NPR science correspondent Rob Stein gives us a glimpse into the global race to create the first artificial human embryos to see how the competition is unfolding.

What your parents didn't tell you about pulling an all-nighter? It just might ease depression for several days. At least, that's what researchers found happens to mice in a study published in the journal Neuron Thursday.
Most people who've stayed up all night know the "tired and wired" feeling they get the next day. Scientists know this feeling can have a strong antidepressant effect in people that lasts for several days, even after the other changes wear off. But this new study may help researchers figure out why sleeplessness causes this effect.
Plus, we get into some other science headlines we can't stop talking about: Turning a centuries-old debate over starfish on its head and record lows for Antarctica's sea ice.

Thanks, Neanderthals: How our ancient relatives could help find new antibiotics
30 oktober 2023 |
13 min
Antibiotics have changed the world. They've made it possible to treat diseases that used to mean anything from discomfort to death. But no new classes of antibiotics have made it to the market since the 1980s. What if humans' closest, ancient relatives held the answer to antibiotic resistance?
Some scientists want to discover new antibiotics using machine learning ... and some very, very old relatives of humans. Host Aaron Scott talks to César de la Fuente about using computers to discover the first therapeutic molecules in extinct organisms.

Scientist Just Made The Largest Brain Map Ever
27 oktober 2023 |
12 min
The human brain has more than 170 billion cells. A newly published atlas offers the most detailed maps yet of the location, structure and, in some cases, function of more than 3,000 types of brain cells. The atlas could help scientists understand what makes humans unique in the animal kingdom and the roles different brain cells play in disease. Science correspondent Jon Hamilton talks to host Regina G. Barber about the findings from this new map, a product of the NIH's BRAIN initiative. Plus, what the heck splatter neurons have to do with all of this!

How Climate Change Is Testing The Endangered Species Act
25 oktober 2023 |
11 min
Some people keep dogs in their backyards. In the Florida Keys, some residents have deer the size of a golden retriever in their yards. As sea levels rise and salt water climbs higher on the islands, it's shrinking habitat for this deer — which already has an estimated population of at most 1,000. Today, host Regina G. Barber hears from reporters Nate Rott and Ryan Kellman about the Key deer, and how rising sea levels are forcing wildlife managers to ask big questions about the future of the subspecies.
In this episode, we incorrectly stated that Valerie Preziosi is the founder of Key Deer Alliance. In fact, she is the founder and director of the organization Save Our Key Deer.

Florida Corals Are Dying. Can A 'Coral Gym' Help Them Survive?
11 oktober 2023 |
13 min
Coral reefs in Florida have lost an estimated 90% of their corals in the last 40 years. And this summer, a record hot marine heat wave hit Florida's coral reefs, exacerbating that problem. Scientists are still assessing the damage as water temperatures cool. And one researcher is taking coral survival a step further: Buffing up corals in a "gym" in his lab. Reporter Kate Furby went to South Florida to see the coral reefs up close and talk to the innovative scientists working to save them.

Choose Your Own Adventure — But Make It Math
9 oktober 2023 |
12 min
Ever read those Choose Your Own Adventure books of the '80s and '90s? As a kid, mathematician Pamela Harris was hooked on them. Years later she realized how much those books have in common with her field, combinatorics, the branch of math concerned with counting. It, too, depends on thinking through endless, branching possibilities. So, she and several of her students set out to write a scholarly paper in the style of Choose Your Own Adventure books. In this encore episode, Dr. Harris tells host Regina G. Barber all about how the project began, how it gets complicated when you throw in wormholes and clowns, and why math is fundamentally a creative act.

Why Chilean Mummies Are Decomposing After 7,000 Years
4 oktober 2023 |
12 min
Here on Short Wave, we're getting into the Halloween spirit a little early with a look at the world's oldest mummies. They're found in modern-day northern Chile. The mummies are well-preserved, so over the past 7,000 years, some have been exhumed for scientific study. But recently, something startling happened: Some of the mummies started to decompose.
Today on the show, Regina G. Barber talks to archeologist Marcela Sepulveda about the civilization that made these mummies: the Chinchorro people. We dig into the science behind their mummification techniques and how the changing planet is affecting archeologists' ability to study the past.

Seaweed is piling up on beaches. This robot might be its match
2 oktober 2023 |
13 min
A new robot is designed to sink sargassum before the stinky seaweed comes ashore. Blooms of sargassum, a leafy brown seaweed, have increased in size and number over the past decade. As the blooms have grown, so too has their impact on coastal communities. The stinky seaweed can wreck local economies and ecosystems — and even threaten human health, some research suggests. But the creators of the AlgaRay say that their robot might do more than halt this damage. It could also fight climate change.

Why Sustainable Seafood Is A Data Problem
20 september 2023 |
14 min
The last several decades have taken a toll on the oceans: Some fish populations are collapsing, plastic is an increasing problem and climate change is leading to coral bleaching — as well as a host of other problems. But marine biologist and World Economic Forum programme lead Alfredo Giron says there's room to hope for the seas. He works to create systems that governments and the fishing industry can use to make sure fishing is legal and sustainable so oceans thrive for years to come. In this encore episode, he talks to host Aaron Scott about his work and how managing the ocean is a lot about managing people.
We spoke to Alfredo Giron about his research and thoughts, the episode is not meant to reflect the World Economic Forum's positions.

The James Webb Space Telescope Is Fueling Galactic Controversy
18 september 2023 |
13 min
We're entering a new era of astrophysics. The James Webb Space Telescope is helping scientists test existing ideas and models of how the universe was created—on a whole new level. This telescope is sending back images of galaxies forming under a billion years after the Big Bang—way earlier than astronomers had previously expected. Not only that, scientists had anticipated that later—but still very early—galaxies would be small, barely formed blobs; instead, the galaxies in these images have spiral arms. So, today's show is all about GALACTIC CONTROVERSY! Computational astrophysicist Jorge Moreno talks with fellow astronomer and Short Wave's Scientist in Residence Regina G. Barber about how these new findings are stirring up controversy in the scientific community and the lessons we can learn from galaxies.

Have frequent, burning pee? Cramping or the urge to pee even though you just went? If you haven't yet, you probably will eventually—along with an estimated 60% of women and 10% of men. That's the large slice of the population that experiences a urinary tract infections (UTI) at least once. Many people avoid talking about these infections, but about one in four women experience recurring UTIs. No matter what they do, the infections come back, again and again. So today on the show, Regina G. Barber takes producer Rachel Carlson on a tour of the urinary tract. We zoom into what recurring UTIs may have to do with changes on the DNA of our bladder cells and the hidden bacterial houses in our bladder walls.

'Speedboat Epidemiology': Eradicating Disease One Person At A Time
30 augusti 2023 |
13 min
Smallpox is a deadly virus. At one point, it killed almost 1 in 3 people who had it. Almost 300 million of those deaths were in the 20th century alone. It was extremely painful, highly contagious and many people thought it would be impossible to wipe out—until it was.
On May 8, 1980. the 33rd World Health Assembly declared the world free of smallpox. This marked the first—and only—time a human disease was eradicated globally.
Epidemiologist and host of the podcast Epidemic: Eradicating Smallpox Céline Gounder has been looking into this history. Today, she shares the intense journey to eradicate smallpox in Bangladesh (spoiler alert: there are literal speedboats) and reflects on what this history tells us about the importance of healthcare that meets the needs of individuals and communities today.

What Do We Do With Radioactive Wastewater?
28 augusti 2023 |
12 min
Workers in Japan started releasing treated radioactive water from the Fukushima Daiichi nuclear power plant into the Pacific Ocean on Thursday. Reactors at the plant began melting down after a 2011 earthquake and tsunami that hit the area. To stop the meltdown, plant workers flooded the reactors with water. But even now, when the plant is offline, the reactors need to be cooled. All that water—about 350 million gallons—is being stored on-site in over 1,000 tanks. And now, these tanks are almost full.
Today on the show, host Regina G. Barber talks to NPR reporters Geoff Brumfiel and Kat Lonsdorf about the official plan for the radioactive wastewater, the science behind the release and why some are unhappy about it.

Fixing Our Failing Electric Grid... On A Budget
21 augusti 2023 |
11 min
It's no secret that our electric grid is a flaming hot mess — and in order to reduce emissions, the U.S. needs to get a lot more renewables onto the grid. But there's a problem: Our electric grid is too old and outdated to handle this new technology. In fact, many of the copper wires on transmission lines are using technology from as far back as the early 1900s!
Because of this, thousands of wind and solar projects are waiting for years to get online. The Inflation Reduction Act is incentivizing a big transition to things like electric cars, heat pumps and other devices, which means we'll need even more electricity that will further push the limits of existing infrastructure.
Now more than ever, we need this new power. With this in mind, some tech companies are finding solutions to make the existing grid work better.
Aaron Scott talks with NPR's climate solutions reporter Julia Simon about these solutions and how they might be a whole lot quicker — and cheaper — than you'd think.

Now more than ever, we need this new power. With this in mind, some tech companies are finding solutions to make the existing grid work better.
Aaron Scott talks with NPR's climate solutions reporter Julia Simon about these solutions and how they might be a whole lot quicker — and cheaper — than you'd think.

This Cellular Atlas Could Lead To Breakthroughs For Endometriosis Patients
19 juli 2023 |
11 min
For people with endometriosis—a mysterious disease where endometrial tissue grows outside of the uterus—medical visits can be especially frustrating. It takes some patients years (on average, ten years) to get a diagnosis and treatment options are limited. There are currently no cures. One researcher, Dr. Kate Lawrenson, is trying to change that. She and her team of researchers have created a cellular atlas of the disease and hope this cell-by-cell approach will open up doors for faster diagnosis options and better ways of managing it. In the meantime, she hopes that more people will learn about the disease in the first place.

Meet The Residents Of The Great Pacific Garbage Patch
17 juli 2023 |
15 min
Trash from humans is constantly spilling into the ocean — so much so that there are five gigantic garbage patches in the seas. They hang out at the nexus of the world's ocean currents, changing shape with the waves. The largest is the Great Pacific Garbage Patch. These areas were long thought to have been uninhabited, the plastics and fishing gear too harmful to marine life. But researchers have recently uncovered a whole ecosystem of life in this largest collection of trash. Today, with the help of marine biologist Fiona Chong, we meet the tiny marine life that calls this place home.

Galaxies Are Older Than We Thought — That's A Big Deal
26 maj 2023 |
12 min
If you ask a physicist or cosmologist about the beginnings of the universe, they'll probably point you to some math and tell you about the Big Bang theory. It's a scientific theory about how the entire universe began, and it's been honed over the decades. But recent images from the James Webb Space Telescope have called the precise timeline of the theory a little bit into question. That's because these images reveal galaxies forming way earlier than was previously understood to be possible. To understand whether it's physics itself or just our imaginations that need help, we called up theoretical physicist Chanda Prescod-Weinstein.

Transplanted organs need diligent care, and Leila had been looking after her donated kidney all on her own for a year. So a lot was riding on that first batch of lab results.
"Immediately, all my levels were just out of whack and I knew that I was in rejection," she says. "I've had to work through a lot of emotional pain, of feeling like I failed my donor. Like, why couldn't I hold on to this kidney?"
On today's episode, editor Gabriel Spitzer walks us through Leila's journey — from spending her late 20s on dialysis, to being saved by a gift and ultimately, to the search for another donated kidney.

A doctor's job is to help patients. With that help, often comes lots and lots of paperwork. That's where some startups are betting artificial intelligence may come in. The hope is that chatbots could generate data like treatment plans that would let doctors spend less time on paperwork and more time with their patients. But some academics warn biases and errors could hurt patients.

SUPERBLOOM: An Upside To The California Downpours
28 april 2023 |
15 min
California's wet winter has devastated many local communities. It has also benefited some of the state's endangered ecosystems. Those benefits are on full display in California's largest remaining grassland. Wetlands, long severed from the rivers and streams that nourished them, are being flooded with freshwater. Biologists are seeing baby salmon, fattened by new food sources in flood plains, make their way to sea. Endangered birds and waterfowl are nesting next to flooded fields. Today, NPR climate correspondent Nate Rott takes us on a tour through California's booming natural beauty.

Fire And Ice: Linking Intense Wildfire And The Melting Arctic
21 april 2023 |
12 min
In the Arctic Ocean, sea ice is shrinking as the climate heats up. In the Western U.S., wildfires are getting increasingly destructive. Those two phenomena are thousands of miles apart, but scientists are uncovering a surprising connection. The ice is connected to weather patterns that reach far across North America. And as the climate keeps changing and sea ice shrinks, Western states could be seeing more extreme weather, the kind that fuels extreme wildfires.

When Tove Danovich decided to dabble in backyard chicken keeping, she embraced a tried and true journalistic practice — reading everything there is to find on the subject. In her search, she found plenty of how-to guides, but what she really wanted was to know more about the science. She wanted to understand their evolution and unique relationship with humans.
"As I was reading more and as I was wanting this book that increasingly it seemed like it it just didn't exist. I wound up writing it instead," says Tove.
Today, Aaron visits Tove in her chicken coop to talk about her recent book Under the Henfluence: Inside the World of Backyard Chickens and the People Who Love Them and to meet the chicken stars of Tove's Instagram account.

Launching Into Space — Sustainably!
10 april 2023 |
13 min
In 1957, the Space Age began with the launch of Sputnik, the first artificial satellite. Since then, the number of objects humans have hurled toward the stars has soared to the thousands. As those objects have collided with one another, they've created more space debris in Earth's orbit. According to some estimates, all of that debris and human-made space trash, the number of objects — from satellites to screws — could be in the millions. In this iteration of our AAAS live show series, Short Wave co-host Aaron Scott talks to Danielle Wood, an assistant professor of aeronautics and astronautics at MIT, about the dangers of accumulating space debris, and how she and others are working to make space more sustainable.

Allergies Are Weird. So Are Cats
5 april 2023 |
14 min
Katie Wu is a bona fide cat person. She has two of them: twin boys named Calvin and Hobbes. Every night, they curl up in bed with her, bonking their little noses together, rubbing their fur and whiskers everywhere, and leaving behind inevitable cat residue. It's certifiably cute ... and a little bit gross.
It's also the worst nightmare for the cat-allergic. Which, just shy of a decade ago, Katie was. In a stroke of luck, Katie's debilitating cat allergy disappeared. The reasons for her immune overhaul remain a mystery.
Allergies can wax and wane over time, but it seems to be less common to have the night-and-day shift that Katie experienced. In this episode, Katie walks host Aaron Scott through the dynamic world of allergies and what it reveals about our immune systems. And of course, Katie's cats make cameo appearances. (encore)

Eunice Foote: The Hidden Grandmother Of Climate Science
31 mars 2023 |
12 min
Today, most climate science is done with satellites, sensors and complicated computer models. But it all started with a pioneering female physicist and two glass tubes. Eunice Foote, the woman behind that glass tube experiment, has largely been left out of the history books. Until about 10 years ago, John Tyndall was seen as the grandfather of climate science for setting the foundation for the understanding of the greenhouse gas effect. But Eunice's experiment, done three years prior, showed that air with more "carbonic acid," or carbon dioxide, both heated up faster and cooled down slower than regular air.

Why Scientists Just Mapped Every Synapse In A Fly Brain
29 mars 2023 |
11 min
To really understand the human brain, scientists say you'd have to map its wiring. The only problem: there are more than 100 trillion different connections to find, trace and characterize. But a team of scientists has made a big stride toward this goal, a complete wiring diagram of a teeny, tiny brain: the fruit fly larva.
With a full map, or connectome, of the larval fruit fly brain, scientists can start to understand how behaviors shape, and are shaped by, the specific wiring of neural circuits.
On today's episode, our resident neuroscience aficionado, NPR science correspondent Jon Hamilton, talks over the new findings with Short Wave co-host Emily Kwong, and explains why we big-brained humans ought to care.

Perennial Rice: Plant Once, Harvest Again And Again
27 mars 2023 |
13 min
Rice is arguably the world's most important staple crop. About half of the global population depends on it for sustenance. But, like other staples such as wheat and corn, rice is cultivated annually. That means replanting the fields year after year, at huge cost to both the farmers and the land. For years, scientists have been tinkering with rice strains to create a perennial variety – one that would regrow after harvest without the need to be resown. Today, Scientist in Residence Regina G. Barber takes a look at one promising perennial rice effort. It's one of a series of interviews we conducted live at the 2023 Annual Meeting of the American Association for the Advancement of Science (AAAS).

Why Pandemic Researchers Are Talking About Raccoon Dogs
23 mars 2023 |
14 min
A few weeks ago, raw data gathered in Janaury 2020 from Huanan Seafood Wholesale Market in Wuhan, China — the early epicenter of the COVID-19 pandemic — was uploaded to an online virology database. It caught the attention of researchers. A new genetic analysis from an international team provides the strongest evidence yet for natural origins of the COVID-19 pandemic and the role of one animal in particular: raccoon dogs. Short Wave co-host Emily Kwong talks with Katherine Wu, a staff writer at The Atlantic, who broke the story and explains the genetic evidence.
To dive into emerging genetic evidence of this pandemic's origins, read:

What we lose if the Great Salt Lake dries up
21 mars 2023 |
13 min
Dotted across the Great Basin of the American West are salty, smelly lakes. The largest of these, by far, is the Great Salt Lake in Utah.
But a recent report found that water diversions for farming, climate change and population growth could mean the lake essentially disappears within five years. Less water going in means higher concentrations of salt and minerals, which threatens the crucial ecological role saline lakes play across the West, as well as the health of the people who live nearby.
On today's episode, Kirk takes Short Wave co-host Aaron Scott on an audio field trip to the endangered Great Salt Lake, and explains why losing the lake could be devastating for everyone from brine flies to the humans that live next door.

Venus And Earth: A Tale Of Two 'Twins'
20 mars 2023 |
14 min
Planetary scientists announced some big news this week about our next-door neighbor, Venus. For the first time, they had found direct evidence that Venus has active, ongoing volcanic activity.
"It's a big deal," says Dr. Martha Gilmore, a planetary geologist at Wesleyan University. "It's a big deal in that there are no other planets, actually, where we've seen active volcanism." (Moons don't count - sorry Io!)
What makes that fact so striking is how inhospitable a place Venus is now – crushing pressure, a toxic atmosphere and a surface temperature around 850 degrees Fahrenheit. So, what happened? How did Earth and its closest sibling diverge so sharply?
On today's episode, Martha talks with scientist in residence Regina G. Barber about what studying Venus can tell us about the past and the future of our own planet.

Flying Into Snowstorms ... For Science!
17 mars 2023 |
13 min
For the past few winters, researchers have been intentionally flying into snowstorms. And high in those icy clouds, the team collected all the information they could to understand—how exactly do winter storms work?
With more accurate data could come more accurate predictions about whether a storm would cause treacherous conditions that shut down schools, close roads and cancel flights. NPR science correspondent Nell Greenfieldboyce recently took to the skies for one of these flights and shares her reporting with us today.

Could de-extincting the dodo help struggling species?
16 mars 2023 |
12 min
As a leading expert on paleogenomics, Beth Shapiro has been hearing the same question ever since she started working on ancient DNA: "The only question that we consistently were asked was, how close are we to bringing a mammoth back to life?"
In the second part of our conversation (listen to yesterday's episode), Beth tells Short Wave co-host Aaron Scott that actually cloning a mammoth is probably not going to happen.
"But there are technologies that will allow us to resurrect extinct traits, to move bits and pieces of genes that might be adapted to a large animal like an elephant living in the Arctic."
That is what companies like Colossal Biosciences and Revive and Restore are trying to do, with Beth's help. And she is leading the effort on another iconic extinct species, the dodo.
In today's episode, how Beth Shapiro's initial work mapping the dodo genome laid the groundwork to bring back a version of it from extinction, and how the knowledge scientists gain from de-extinction could help protect species under threat now.

It's Boom Times In Ancient DNA
15 mars 2023 |
14 min
Research into very, very old DNA has made huge leaps forward over the last two decades. That has allowed scientists like Beth Shapiro to push the frontier further and further.
"For a long time, we thought, you know, maybe the limit is going to be around 100,000 years [old]. Or, maybe the limit is going to be around 300,000 years," says Shapiro, Professor of Ecology & Evolutionary Biology at UC Santa Cruz. "Well, now we've been working with a horse fossil in Alaska that's about 800,000 years old."
Beth's career has spanned the heyday of ancient DNA research, beginning in the late 1990s when rapid genetic sequencing technology was in its early days. She talked with Short Wave co-host Aaron Scott about the expanding range of scientific puzzles the young field is tackling — from new insights into our Neanderthal inheritance to deep questions about ecology and evolution.

How Well Does A New Alzheimer's Drug Work For Those Most At Risk?
13 mars 2023 |
14 min
A new drug for Alzheimer's disease, called lecanemab, got a lot of attention earlier this year for getting fast-tracked approval based on a clinical trial that included nearly 1,800 people. It was the most diverse trial for an Alzheimer's treatment to date, but still not enough to definitively say if the drug is effective for Black people. "[In] the world's most diverse Alzheimer's trial, a giant trial of 1,800 people that lasted for a much longer time than most trials did, we're still not sure that all of the groups that are at highest risk of Alzheimer's disease actually see any kind of benefit," says Dr. Jonathan Jackson, Assistant Professor of Neurology at Harvard Medical School.
On today's episode, Jonathan and Short Wave co-host Emily Kwong delve into how drug developers can overlook those hardest hit by the disease they're trying to treat.

'Are You A Model?': Crickets Are So Hot Right Now
9 mars 2023 |
14 min
Have you ever wondered how biologists choose what animal to use in their research? Since scientists can't do a lot of basic research on people, they study animals to shed light on everything from human health to ecosystems to genetics. And yet, just a handful of critters appear over and over again. Why the mouse? Or the fruit fly? Or the zebrafish?
Cassandra Extavour, an evolutionary biologist at Harvard, talked with Short Wave co-host Aaron Scott about her favorite new model critter on the block: crickets. (Well, "favorite" might be a strong word. As Cassandra concedes, "to be honest, my opinion about crickets is sort of neutral to slightly grossed out.")
On today's episode we leave the mouse to its maze, and instead consider the cricket and all the amazing things it can teach us.

The Race To Save A Tree Species
8 mars 2023 |
11 min
The whitebark pine is a hardy tree that grows in an area stretching from British Columbia, Canada south to parts of California and east to Montana. It's a keystone species in its subalpine and timberline ecosystems and plays an outsized role in its interactions with other species and the land — feeding and providing habitat for other animals, and providing shade to slow glacial melt to the valleys below. But it's increasingly threatened — by more intense fires, by mountain pine beetle infestations and by a deadly fungus called blister rust. Today, producer Berly McCoy takes the microphone to share the ongoing efforts by reforestation forester ShiNaasha Pete and others to save this important species.

The $20 Billion Deal To Get Indonesia Off Coal
7 mars 2023 |
12 min
Indonesia is the world's largest exporter of coal for electricity. And it's also an emerging economy trying to address climate change. The country recently signed a highly publicized, $20 billion international deal to transition away from coal and toward renewable energy. The hope is the deal could be a model for other countries. But Indonesian energy experts and solar executives worry much of this deal may be "omong kosong" — empty talk. Today, NPR climate solutions reporter Julia Simon breaks down the realities and limitations of Indonesia's renewable aspirations.

Rome wasn't built in a day, but they sure had strong concrete
6 mars 2023 |
13 min
The Roman Colosseum is a giant, oval amphitheater built almost two thousand years ago. Despite its age and a 14th century earthquake that knocked down the south side of the colosseum, most of the 150-some foot building is still standing. Like many ancient Roman structures, parts of it were constructed using a specific type of concrete. Scientists and engineers have long suspected a key to these buildings' durability is their use of this Roman concrete. But exactly how this sturdy concrete has contributed to the architecture's strength has been a mystery to researchers across the globe.
A team of interdisciplinary researchers have recently discovered one answer to why these ancient Roman buildings have weathered the test of time — while many modern, concrete structures seem to crumble after a few decades.
The answer: self-healing concrete.

Measuring Health Risks After A Chemical Spill
27 februari 2023 |
12 min
This week, the Environmental Protection Agency (EPA) will hold a public hearing about its remediation plan for cleaning up chemicals in and around East Palestine, Ohio. It follows the derailment of a Norfolk Southern train carrying hazardous chemicals like vinyl chloride and butyl acrylate near the town earlier this month. Residents were temporarily evacuated from the area two days later to allow for a controlled burn of the chemicals. EPA health officials have been monitoring the air and water in the area and testing for chemicals as part of their human health risk assessment. We wanted to know: What goes into an assessment like that? And how does the EPA know if people are safe — now and long-term? To walk us through that assessment, we talked to Karen Dannemiller, an associate professor of environmental health science at The Ohio State University.

Ancient Seeds: A Possible Key To Climate Adaptation
24 februari 2023 |
14 min
In the Bekaa Valley region of Lebanon, there is a giant walk-in fridge housing tens of thousands of seeds. They belong to the International Center for Agricultural Research in the Dry Areas (ICARDA). Scientists from around the world use the seeds for research. ICARDA seeds have improved food security in several countries. They've transformed Ethiopian agriculture to use more drought-resistant crops. A new chickpea can be planted in winter. And now, NPR's Middle East correspondent Ruth Sherlock has found that some scientists are turning to the seed bank for answers to a hotter, drier planet. They're hoping ICARDA seeds will lead to breakthroughs in certain crops' resilience to the effects of climate change.

Understanding Earthquake Aftershocks
22 februari 2023 |
10 min
Monday another earthquake struck southeastern Turkey, near the Syrian border. This time, the quake registered as a magnitude 6.3 — an order lower than the initial, devastating 7.8 magnitude earthquake and the magnitude 7.5 aftershock that struck the area two weeks ago on Feb. 6. A magnitude 6.3 is still considered strong, according to the United States Geological Survey (USGS). And as NPR previously reported, some locals were inside buildings trying to recover belongings lost in the initial quake when Monday's aftershock hit.
It made us wonder: What are aftershocks? And how long will people in Turkey and neighboring countries like Syria have to endure aftershocks while piecing their lives back together? Days? Years?
For answers, we turned to earthquake geologist Wendy Bohon, who we've previously spoken to about the limitations of earthquake detection.

The Science Fueling Disney's 'Strange World'
16 februari 2023 |
14 min
In Disney's new animated feature 'Strange World,' a band of multigenerational explorers journeys to the center of their fantastical homeland. Along the way, they fend off, make friends with, and unearth secrets about the curious creatures who call this place home. There's the filterlopes, six-legged deer-forms with fan-like antennae. Or scouts, squishy blue balls with 12 elastic limbs. But as fantastical as these creatures sound, each one is grounded in the physics and biology of its real-world counterpart.
Enter married couple Elizabeth Rega and Stuart Sumida, professors of anatomy and paleontology, respectively. They've worked as science consultants on more than 70 films, from 'Ratatouille' to 'Guardians of the Galaxy.' Film crews bring the duo onboard as biology experts, to help animators figure out how their animal creations — and sometimes their imaginary beasts — should look and move. But 'Strange World' may be their biggest undertaking yet; Elizabeth and Stuart entered at the earliest stages of production to help envision the kinds of creatures that would fill this world with science and wonder.

Mix Up LOVE, And You Get V-O-L-E
14 februari 2023 |
11 min
You may have heard of the "love hormone," or oxytocin. But you may not know that scientists have relied on cuddly rodents like the prairie vole to help us understand how this protein works in our brains.
Voles are stocky, mouse-like little mammals that range over most of North America. One species in particular, the prairie vole, is known for its fidelity: Prairie voles pair-bond and mate for life.
And so, for years, scientists have known that oxytocin is important in facilitating the feeling of love in both humans and voles. However, a new study suggests love can prevail even without the "love hormone" – at least among prairie voles.
On today's episode, NPR's science correspondent Jon Hamilton tells Short Wave co-host Emily Kwong how prairie voles, once again, are helping us understand and appreciate something as abstract as love.

Meet One Engineer Fixing A Racially Biased Medical Device
13 februari 2023 |
14 min
During the COVID-19 pandemic, one measurement became more important than almost any other: blood oxygen saturation. It was the one concrete number that doctors could use to judge how severe a case of COVID-19 was and know whether to admit people into the hospital and provide them with supplemental oxygen.

Lightning Protection: Lasers, Rockets or Rods?
10 februari 2023 |
12 min
Every year, lightning is estimated to cause up to 24,000 deaths globally. It starts forest fires, burns buildings and crops, and causes disruptive power outages. The best, most practical technology available to deflect lightning is the simple lightning rod, created by Benjamin Franklin more than 250 years ago. But lightning rods protect only a very limited area proportional to their height. So today's show, why a group of European researchers are hoping the 21 century upgrade is a high-powered laser. Plus: Regina makes incremental progress on conquering her irrational fear of lightning.

The Social Cost of Carbon Is An Ethics Nightmare
9 februari 2023 |
14 min
One of the most important tools the federal government has for cracking down on greenhouse gas emissions is a single number: the social cost of carbon. It represents all the damage from carbon emissions — everything from the cost of lost crops and flooded homes to the lost wages when people can't safely work outside and the cost of climate-related deaths. Currently, the cost is $51 per ton of carbon, but the Environmental Protection Agency has proposed raising the cost to $190.
NPR climate correspondent Rebecca Hersher tells Aaron how the change could dramatically alter how the government confronts climate change, and why the new number is simultaneously more accurate and an ethics nightmare.

Why Can't We Predict Earthquakes?
8 februari 2023 |
12 min
In the wake of the massive earthquake in Turkey and Syria, many scientists have been saying this area was "overdue" for a major quake. But no one knew just when: No scientist has "ever predicted a major earthquake," the U.S. Geological Survey says. Even the most promising earthquake models can only offer seconds of warning. In this episode, host Emily Kwong talks to geologist Wendy Bohon and NPR science correspondent Geoff Brumfiel about why earthquake prediction can be so difficult, and the science that fuels these models.

Who Gets The First Peek At The Secrets Of The Universe?
7 februari 2023 |
11 min
The James Webb Space Telescope is by far the most powerful space-based telescope ever deployed by the United States. But it is only one instrument, and scientists all over the world have to share. The JWST's managers received more than 1,600 research proposals for what the telescope should look at.
When an astronomer or a team does get some much-coveted telescope time, they currently get exclusive access to whatever data they collect for a full year. But there is a movement in astronomy to make most results open-access right away. That might speed up the pace of scientific discoveries and open up the data to a much wider set of researchers. On the other hand, some astronomers worry that instant open access would mostly benefit researchers who already have advantages.
In this episode, NPR's Nell Greenfieldboyce talks with Short Wave scientist in residence Regina G. Barber, who has firsthand experience competing for telescope time, about who gets dibs on the data, and how that could affect equity in astronomy.

A Fatal Virus With Pandemic Potential
2 februari 2023 |
12 min
The Nipah virus is on the World Health Organization's short list of diseases that have pandemic potential and therefore pose the greatest public health risk. With a fatality rate at about 70%, it is one of the most deadly respiratory diseases health officials have ever seen. But as regular outbreaks began in the early 2000s in Bangladesh, researchers were left scratching their heads. Initially, the cause of the outbreaks was unknown to them. But once they identified the virus, a second, urgent question arose: How was the virus jumping from bats into humans?

The Ancient Night Sky And The Earliest Astronomers
1 februari 2023 |
15 min
Moiya McTier says the night sky has been fueling humans' stories about the universe for a very long time, and informing how they explain the natural world. In fact, Moiya sees astronomy and folklore as two sides of the same coin.
"To me, science is any rigorous attempt at understanding and explaining the world around you," she explained to Short Wave's Aaron Scott. "You can see that they knew enough about the world around them to predict eclipses, to predict annual floods in Egypt, for example. I think that you can use folklore and mythology to understand the early scientific attempts of humanity."
Moiya McTier is the author of The Milky Way: An Autobiography of our Galaxy. She joins us to draw out the connections between astronomy and folklore, why the night sky is more dynamic than it might look, and what it feels like to live on an astronomical timescale.

Gas Stoves: Sorting Fact From Fiction
30 januari 2023 |
13 min
Gas stoves are found in around 40% of homes in the United States, and they've been getting a lot of attention lately. A recent interview with Richard Trumka, the commissioner of the U.S. Consumer Product Safety Commission (CPSC), quickly became fodder for outrage, viral disinformation and political fundraising after he proposed regulating the appliance. The proposal stems from a growing body of research suggesting gas stoves are unhealthy — especially for those with asthma, chronic obstructive pulmonary disease and children. NPR climate and energy correspondent Jeff Brady joins us today to separate fact from fiction.

Meet The Bony-Eared Assfish And Its Deep Sea Friends
27 januari 2023 |
13 min
Yi-Kai Tea, a biodiversity research fellow at the Australian Museum in Sydney, has amassed a social media following as @KaiTheFishGuy for his sassy writing and gorgeous photos of fish and other wildlife.
Kai recently returned from an expedition aboard an Australian research ship to explore the deep seas surrounding a new marine park in the Indian Ocean. Led by the Museums Victoria Research Institute, dozens of scientists aboard mapped the ocean floor and, using nets dropped to as deep as six kilometers, gathered thousands of specimens, ranging from the utterly adorable deep sea batfish to the terrifying highfin lizardfish to the unfortunately named bony-eared assfish.
Today on the show, Kai takes host Aaron Scott on a tour of the ocean floor and the fantastical creatures that call it home.
"They are masters of the realm," says Kai. "You can't live in 3,000 meters of water and not be a master at what you do. And the fact that these creatures are living down there, thriving and making the most out of these habitats, that's a remarkable feat."

6 Doctors Swallow Lego Heads ... What Comes Out?
26 januari 2023 |
16 min
As an emergency physician at Western Health, in Melbourne, Australia, Dr. Andy Tagg says he meets a lot of anxious parents whose children have swallowed Lego pieces. Much like Andy so many years ago, the vast majority of kids simply pass the object through their stool within a day or so. But Andy and five other pediatricians wondered, is there a way to give parents extra reassurance ... through science?
So the doctors devised an experiment. "Each of them swallowed a Lego head," says science journalist Sabrina Imbler, who wrote about the experiment for The Defector. "They wanted to basically see how long it took to swallow and excrete a plastic toy." On today's episode, Sabrina joins Scientist in Residence Regina G. Barber to chart the journey of six lego heads, and what came out on the other side.
Learn about Sabrina Imbler's recent book, How Far the Light Reaches, at their website.
Editor's note: This episode contains frequent and mildly graphic mentions of poop. It may cause giggles in children, and certain adults.

Our Perception Of Time Shapes The Way We Think About Climate Change
24 januari 2023 |
10 min
Most people are focused on the present: today, tomorrow, maybe next year. Fixing your flat tire is more pressing than figuring out if you should buy an electric car. Living by the beach is a lot more fun than figuring out when your house might be flooded by rising sea levels.
That basic human relationship with time makes climate change a tricky problem.

Fossil CSI: Cracking The Case Of An Ancient Reptile Graveyard
23 januari 2023 |
13 min
This mystery begins in 1952, in the Nevada desert, when a self-taught geologist came across the skeleton of a massive creature that looked like a cross between a whale and a crocodile. It turned out to be just the beginning.
Ichthyosaurs were bus-sized marine reptiles that lived during the age of dinosaurs, when this area of Nevada was underwater. Yet paleontologists found few other animals here, which raised the questions: Why were there so many adult ichthyosaurs, and almost nothing else? What could have killed them all?
Paleontologist Neil Kelley says that recently, there has been a major break in the case—some new evidence, and a hypothesis that finally seems to fit. Neil talked with Short Wave co-host Aaron Scott about his theory of the case, and why it matters to our understanding of the past.

New Tech Targets Epilepsy With Lasers, Robots
20 januari 2023 |
14 min
About three million people in the United States have epilepsy, including about a million who can't rely on medication to control their seizures. For years, those patients had very limited options. But now, in 2023, advancements in diagnosing and treating epilepsy are showing great promise for many patients, even those who had been told there was nothing that could be done. Using precise lasers, microelectronic arrays and robot surgeons, doctors and researchers have begun to think differently about epilepsy and its treatment. Today on Short Wave, host Aaron Scott talks with NPR science correspondent Jon Hamilton about these advances in treating epilepsy. He explains why folks should ask their doctors about surgery — even if it wasn't an option for them a few years ago.

Time Is So Much Weirder Than It Seems
18 januari 2023 |
14 min
Time is a concept so central to our daily lives. Yet, the closer scientists look at it, the more it seems to fall apart. Time ticks by differently at sea level than it does on a mountaintop. The universe's expansion slows time's passage. "And some scientists think time might not even be 'real' — or at least not fundamental," says NPR science correspondent Geoff Brumfiel. Geoff joined Short Wave Scientist in Residence Regina G. Barber to bend our brains with his learnings about the true nature of time. Along the way, we visit the atomic clocks at the National Institute of Standards and Technology, consider distant exploding stars and parse the remains of subatomic collisions.

Are humans ever satisfied? Two social psychologists, Ethan Ludwin-Peery and Adam Mastroianni, fell down a research rabbit hole accidentally answering a version of this very question. After conducting several studies, the pair found that when asked how things could be different, people tend to give one kind of answer, regardless of how the question is asked or how good life felt when they were asked. Short Wave's Scientist in Residence Regina G. Barber digs into the research—and how it might reveal a fundamental law of psychology about human satisfaction.

There's always a moment of intense isolation when Jessica Mejía gets dropped off on the Greenland ice sheet for a multi-week research stint. "You know you're very much alone," said Jessica, a postdoctoral researcher in glaciology at the University of Buffalo. Glaciers such as those that cover Greenland are melting due to climate change, causing sea levels to rise. That we know. But these glaciers are also moving. What we don't know is just how these two processes – melting and movement – interact and ultimately impact how quickly sea levels will rise. Jessica Mejía, a postdoctoral researcher in glaciology at the University of Buffalo, joins Short Wave's Aaron Scott to explain what it's like to live on a glacier for a month, and what her research could mean for coastal communities all over the world.

Zircon: The Keeper Of Earth's Time
10 januari 2023 |
12 min
The mineral zircon is the oldest known piece of Earth existing on the surface today. The oldest bits date back as far as 4.37 billion years — not too far from the age of Earth itself at about 4.5 billion years old. And, unlike other minerals, zircon is hard to get rid of. This resilience enables scientists to use zircon to determine when major geological events on Earth happened. As part of our series on time, host Aaron Scott talks to science correspondent Nell Greenfieldboyce about why this mineral is often considered a geologic clock and has earned the nickname "Time Lord."

An Atmospheric River Runs Through It
6 januari 2023 |
12 min
From space, it looks almost elegant: a narrow plume cascading off the Pacific Ocean, spilling gently over the California coast. But from the ground, it looks like trouble: flash flooding, landslides and power outages. California is enduring the effects of an atmospheric river, a meteorological phenomenon where converging air systems funnel wet air into a long, riverine flow that dumps large amounts of rain when it makes landfall. "Atmospheric rivers can transport volumes of water many times that of the Mississippi River," says Dr. Daniel Swain, a climate scientist with UCLA, the National Center for Atmospheric Research, and the Nature Conservancy of California. Daniel joined Short Wave's Aaron Scott to explain where these "rivers" of air come from, how climate change is fueling more of them, and why you're a lot more likely to have heard of them if you happen to live on the west coast of almost any continent.

Climate Change Stresses Out These Chipmunks. Why Are Their Cousins So Chill?
23 december 2022 |
12 min
Kwasi Wrensford describes the subjects of his research as "elfin": skittish little squirrel-cousins with angular faces, pointy ears and narrow, furry tails. He studies two species in particular: the Alpine chipmunk and the Lodgepole chipmunk. As the climate warms, these two chipmunks have developed different ways of coping. The Alpine chipmunk has climbed higher, in search of cooler habitat, while the Lodgepole chipmunk continues to thrive in its historic habitat. On this episode, Kwasi explains to Emily Kwong how these squirrelly critters typify two important evolutionary strategies, and why they could shed light on what's in store for other creatures all over the globe.

Can COP 15 Save Our Planet's Biodiversity?
22 december 2022 |
15 min
This week, the UN Biodiversity Conference (COP 15) wrapped up in Montreal, Canada. Nations from around the world came together to establish a new set of goals to help preserve the planet's biodiversity and reduce the rate of loss of natural habitats. The last time biodiversity targets were set was in 2010, at COP 10. In the 12 years since, the world collectively failed to meet any of those biodiversity benchmarks.
Aaron Scott talks to Giuliana Viglione, an editor at Carbon Brief covering food, land and nature. She shares what she saw on the ground at COP 15, what the new goals for 2030 are, and why she has more hope that progress will be made this time around.

Brain Scientists Are Tripping Out Over Psychedelics
21 december 2022 |
11 min
Psychedelic drugs – like LSD, salvia, ayahuasca, Ibogaine, MDMA (AKA ecstasy), or psilocybin (AKA 'magic mushrooms' or 'shrooms') – are experiencing a resurgence of interest in their potential medical benefits.
At the Neuroscience 2022 meeting held by the Society of Neuroscience, the appetite for psychedelic research permeated the sessions, discussions, and even after-hours barroom talk — drawing in researchers, neuroscientists, companies, reporters, and advocates alike.
"In the last couple of years there has been a lot of excitement in psychedelics. I think it started first in the popular media." says Alex Kwan, associate professor at Cornell University. "Neuroscience, actually, I think took another year or two to catch on."
Today on the show, host Aaron Scott and NPR's brain correspondent Jon Hamilton chat psychedelic drugs — whether this renewed interest will represent incremental or revolutionary changes in the fields of medicine, psychology, and neuroscience.

Dietary supplements — the vitamins, herbs and botanicals that you'll find in most grocery stores — are everywhere. More than half of U.S. adults over 20 take them, spending almost $50 billion on vitamins and other supplements in 2021. Yet decades of research have produced little evidence that they really work. Aaron Scott talks to Dr. Jenny Jia about the science of dietary supplements: which ones might help, which ones might hurt, and where we could be spending our money instead.

A Step Closer To Nuclear Fusion Energy
15 december 2022 |
8 min
On Dec. 5 at 1 o'clock in the morning local time, researchers at the Lawrence Livermore National Laboratory in California used lasers to zap a tiny pellet of hydrogen fuel. The lasers hit their target with 2.05 megajoules of energy, and the pellet released roughly 3.15 megajoules. It's a major milestone, and one that the field of fusion science has struggled to reach for more than half a century: producing a fusion reaction that generates more energy than it consumes. While progress, the technology is still a ways off from its promise to produce energy without creating greenhouse gases. Today on the show, Regina G. Barber brings us two NPR stories that explain what this experiment showed and what else needs to happen to make fusion a practical energy source.

From Scientific Exile To Gene Editing Pioneer
14 december 2022 |
12 min
Gene editing was a new idea in the mid-1970s. So when Harvard and MIT planned new research in recombinant DNA, alarm bells went off. "People were worried about a 'Frankengene,'" says Lydia Villa-Komaroff, then a freshly minted PhD. Amidst a political circus, the city of Cambridge, Massachusetts banned research into recombinant DNA, forcing scientists like Villa-Komaroff into exile. But that turned out to be just the prelude to a breakthrough. In this episode, Dr. Villa-Komaroff tells Emily Kwong the story of overcoming the skeptics and coaxing bacteria into producing insulin for humans.

TFW when you're so excited you get those butterflies in your stomach - or maybe when you see something icky, you feel ill. On today's show, producer Berly McCoy looks at this relationship between our gut and our brain. Berly talks to host Emily Kwong about how the organs evolved to have a tight connection - connections that go beyond transient feelings of excitement or disgust. In fact, an increasing body of research shows links between the gut and conditions we typically associate mostly with the brain – like anxiety and Parkinson's Disease.

DART: The Impacts Of Slamming A Spacecraft Into An Asteroid
9 december 2022 |
14 min
If an asteroid were hurling through space, making a beeline straight to Earth, how would humans prevent it from doing what it did to the dinosaurs? Would we bomb it? Would we shoot lasers at it like a scene from Hollywood's latest sci-fi flick? Well, the folks at NASA have designed and tested a theory.
"The DART mission, the Double Asteroid Redirection Test, is essentially our first test of a kinetic impact for planetary defense." says Cristina Thomas, assistant professor of Astronomy and Planetary Science at Northern Arizona University.
Put simply, scientists at NASA took a spacecraft and crashed it into an asteroid — hoping the little nudge, like bumper cars, would be enough to push the asteroid off course.
Today on the show, Short Wave's scientist-in-residence Regina G. Barber talks to Cristina Thomas about what it was like watching the success of the DART mission and what this means for science and planetary defense.

Don't Call It Dirt: The Science Of Soil
5 december 2022 |
12 min
It's easy to overlook the soil beneath our feet, or to think of it as just dirt to be cleaned up. But soil wraps the world in an envelope of life: It grows our food, regulates our climate, and makes our planet habitable. "What stands between life and lifelessness on our planet Earth is this thin layer of soil that exists on the Earth's surface," says Asmeret Asefaw Berhe, a soil scientist at the University of California-Merced.
Just ... don't call it dirt.
"I don't like the D-word," Berhe says. Berhe says soil is precious, taking millennia to regenerate. And with about a third of the world's soil degraded, according to a UN estimate, it's also at risk. Prof. Berhe, who is also serving as Director of the U. S. Dept. of Energy's Office of Science, marks World Soil Day by telling Aaron Scott about the hidden majesty of soil and why it's crucial to tackling the climate crisis.

A Deeply Personal Race Against A Fatal Brain Disease
21 november 2022 |
14 min
In the mornings, Sonia Vallabh and Eric Minikel's first job is to get their two garrulous kids awake, fed and out the door to daycare and kindergarten. They then reconvene at the office and turn their focus to their all-consuming mission: to cure, treat, or prevent genetic prion disease.
Prions are self-replicating proteins that can cause fatal brain disease. For a decade, Sonia Vallabh has been living with the knowledge that she has a genetic mutation that will likely cause in her the same disease that claimed her mother's life in 2010. Upon discovering she had the mutation, Sonia and her husband made a massive pivot: They went from careers in law and urban planning to earning their Ph.D.s, and founding a prion research lab at the Broad Institute of MIT and Harvard. On today's episode, Sonia and Eric talk with Short Wave's Gabriel Spitzer about what it's like to run a lab with one's spouse, cope with the ticking clock in Sonia's genes, and find hope in a bleak diagnosis.

Killer Proteins: The Science Of Prions
17 november 2022 |
13 min
Prions are biological anomalies – self-replicating, not-alive little particles that can misfold into an unstoppable juggernaut of fatal disease. Prions don't contain genes, and yet they make more of themselves. That has forced scientists to rethink the "central dogma" of molecular biology: that biological information is always passed on through genes. The journey to discovering, describing, and ultimately understanding how prions work began with a medical mystery in a remote part of New Guinea in the 1950s. The indigenous Fore people were experiencing a horrific epidemic of rapid brain-wasting disease. The illness was claiming otherwise healthy people, often taking their lives within months of diagnosis. Solving the puzzle would help unlock one of the more remarkable discoveries in late-20th-century medicine, and introduce the world to a rare but potent new kind of pathogen. For the first episode in a series of three about prion disease, Short Wave's Gabriel Spitzer shares the science behind these proteins with Emily Kwong, and explains why prions keep him awake at night.

COP-out: Who's Liable For Climate Change Destruction?
7 november 2022 |
12 min
World leaders have gathered in Egypt this week to begin climate talks at the 27th Conference of the Parties. However, there are still outstanding questions about who should pay for climate change losses and damages. Vulnerable countries hit hardest by climate change are asking the wealthier countries most responsible for these damages for compensation.
Climate change correspondent Lauren Sommer joins Emily Kwong to talk about this debate — and the case one island nation is making to seek payment.

Control: Eugenics And The Corruption Of Science
4 november 2022 |
14 min
In 1859, Charles Darwin published On the Origin of Species, a book about the evolution of non-human animals by natural selection. In its wake, a political idea arose — eugenics. Reading Darwin's book, Sir Francis Galton proposed that humans should be bred to give more "suitable" characteristics a "better chance of prevailing." Today, producer Rebecca Ramirez talks to Adam Rutherford about his new book, Control: The Dark History and Troubling Present of Eugenics, which traces the inextricable link between political ideology and science, and the enduring shadow of eugenics.

Saving The Pacific Lamprey
1 november 2022 |
16 min
Pacific lamprey have lived on Earth for about 450 million years. When humans came along, a deep relationship formed between Pacific lamprey and Native American tribes across the western United States. But in the last few decades, tribal elders noticed that pacific lamprey populations have plummeted, due in part to habitat loss and dams built along the Columbia River. So today, an introduction to Pacific lamprey: its unique biology, cultural legacy in the Pacific Northwest and the people who are fighting to save it. (Encore)

Donate Your Body To Science?
31 oktober 2022 |
13 min
Halloween calls to mind graveyards and the walking dead, so, naturally, Short Wave wanted to know what happens when you donate your body to real scientists. Host Aaron Scott talked with journalist Abby Ohlheiser about their reporting trips to a Forensic Osteology Research Station and an anatomy lab to learn how donated bodies help everyone from surgeons to law enforcement to forensic archeologists do their jobs. And while this episode might not be for the squeamish, Abby says these spaces of death are not morbid. Instead, they are surprisingly peaceful. You can read Abby's full article in the MIT Technology Review.

The common box turtle is found just about anywhere in the continental United States east of Colorado. For all their ubiquity, it's unclear how many there are or how they're faring in the face of many threats—from lawn mowers to climate change to criminals. So today, science correspondent Nell Greenfieldboyce presents the researchers hunting for turtles—and for answers. They're creating a century-long study to monitor thousands of box turtles in North Carolina.

He Had His Father's Voice: Tracking A Rare Bird Hybrid
27 oktober 2022 |
13 min
When Steve Gosser heard the song of a scarlet tanager in the woods, he knew to look for a bright-red bird with black wings. But when he laid eyes on the singer, he saw instead a dark-colored head, black-and-white body, with a splash of red on its chest. "Well, that sort of looks like a first-year male rose-breasted grosbeak," he said. The song of one bird coming out of the body of another suggested this little guy could be a rare hybrid. Gosser enlisted the help of some pros, including biologist David Toews, who conducted a genetic analysis to see if this was truly the offspring of two species that diverged 10 million years ago, and today run in very different circles. On today's episode, Gosser and Toews fill Aaron in on this avian mystery, and what hybrid animals can teach us about evolution.

New Discoveries In Underwater Plant Sex
24 oktober 2022 |
11 min
Plants living underwater can't count on pollinating insects to get it on. The prevailing theory has been that pollen moves underwater simply by floating around in water currents. But a team of researchers co-led by Dr. Vivianne Solís-Weiss, have discovered a helper organism pitching in to pollinate seagrasses: marine worms. In today's episode, Vivianne tells Short Wave Scientist in Residence Regina G. Barber how she happened to catch these worms, called polychaetes, in the act of pollinating seagrass flowers underwater, and how the discovery is shedding new light on evolution in the oceans.

Ever read those Choose Your Own Adventure books of the 80s and 90s? As a kid, Dr. Pamela Harris was hooked on them. Years later she realized how much those books have in common with her field: combinatorics, the branch of math concerned with counting. It, too, depends on thinking through endless, branching possibilities. She and several students set out to write a scholarly paper in the style of Choose Your Own Adventure books. Dr. Harris tells Regina G. Barber all about how the project began, how it gets complicated when you throw in wormholes and clowns, and why math is fundamentally a creative act.

The Quest To Save The California Condor
11 oktober 2022 |
12 min
The California condor used to soar across the western skies of North America, but by the 1980s, the bird was on the edge of extinction — just 22 remained. Thanks to decades of conservation work, the California condor population has rebounded to a couple hundred birds in Central California and Arizona.
This past May, a large partnership led by the Yurok Tribe re-introduced the birds to Northern California. Today, host Aaron Scott talks to Yurok biologist Tiana Williams-Claussen about the years-long quest to return the birds to their ancestral skies, and the importance of condor — who the Yurok call Prey-go-neesh — to the Yurok people and the natural world.

A New Drug For A Relentless Brain Disease

ALS is a disease that destroys the nerve cells in the brain and spinal cord we need for voluntary movement. There is no cure, but now there is a newly approved medication that may slow down the disease and extend patients' lives. The drug, called Relyvrio, got its start with a couple of college students, some "ice bucket challenge" money, and a new approach to targeting this disease. Neuroscience correspondent Jon Hamilton checks in with host Emily Kwong about why some advisors aren't persuaded the drug works and how you weigh promising but limited evidence against the backdrop of a 100% fatal disease with hardly any other treatment options?

Why Disaster Relief Underserves Those Who Need It Most

When a disaster like Hurricane Ian destroys a house, the clock starts ticking. It gets harder for sick people to take their medications, medical devices may stop working without electricity, excessive temperatures, mold, or other factors may threaten someone's health. Every day without stable shelter puts people in danger.
The federal government is supposed to help prevent that cascade of problems, but an NPR investigation finds that the people who need help the most are often less likely to get it. Today we encore a conversation between NPR climate reporter Rebecca Hersher and Short Wave guest host Rhitu Chatterjee.

In the final episode of Short Wave's Summer Road Trip series exploring the science happening in national parks and public lands, Aaron talks to National Park Service Director Charles Sams, who recently issued new policy guidance to strengthen the ways the park service collaborates with American Indian and Alaska Native Tribes, the Native Hawaiian Community, and other indigenous peoples. It's part of a push across the federal government to increase the level of tribal co-stewardship over public lands. Aaron talks with Sams, the first Tribal citizen to head the agency, about how he hopes this will change the way parks are managed, how the parks are already incorporating Traditional Ecological Knowledge, and what national parkland meant to him growing up as a member of the Cayuse and Walla Walla tribes on the Umatilla Indian Reservation in eastern Oregon.

A century ago, astronomers were locked in a debate about the scope of our universe. Were we it?
The answer is no. There are other galaxies beyond the Milky Way, and they are speeding away from us. Answering that question left astronomers with an even bigger puzzle. Why is everything sprinting away from us and what does that mean for the center of the universe? Today, Scientist in Residence Regina G. Barber brings back astronomer Dr. Vicky Scowcroft for the final episode in our series on cosmic distances and humanity's place in the universe. It's a big one: The mystery of our expanding universe.

Barber brings back astronomer Dr. Vicky Scowcroft for the final episode in our series on cosmic distances and humanity's place in the universe. It's a big one: The mystery of our expanding universe.

The Race To Rescue The Guadalupe Fescue
9 september 2022 |
13 min
Big Bend National Park in Texas is home to the only remaining Guadalupe fescue in the United States. The grass is tucked away in the Chisos Mountains, high above the Chihuahuan Desert. These mountaintops form a string of relatively wet, cool oases called "sky islands" — unique, isolated habitats. But as the planet warms, species that depend on "sky island" habitats tend to get pushed even higher up the mountain — until they eventually run out. Carolyn Whiting, Park Botanist at Big Bend, talks to host Aaron Scott about why the little things are worth preserving.

Short Wave Goes To The Circus
8 september 2022 |
13 min
Julia Ruth has a pretty cool job: it takes a lot of strength, a lot of balance, and a surprising amount of physics.
As a circus artist, Julia has performed her acrobatic Cyr wheel routine around the world. But before she learned her trade and entered the limelight, she was on a very different career path--she was studying physics.
Julia talks with Emily (who also shares a past life in the circus) about her journey from physicist to circus artist, and how she learned her physics-defining acts.

'Scallop Discos': How Some Glitzy Lights Could Lead To A Low-Impact Fishery
7 september 2022 |
15 min
Scientists in the UK have discovered that if they take a pot meant for catching crabs and just add some bright lights, scallops flock through the door like it's Studio 54. Scallops are normally fished via trawling or dredging—methods that can cause lasting damage to delicate seafloor ecosystems. So this accidental discovery (the lights were initially added to attract crab) could have a significant impact on scallop fishing. We talk with one of the scientists, Robert Enever of Fishtek Marine, a company that creates sustainable fishing gear, about this collaboration between science, industry and conservation.

Worm Blobs From The Bowels Of The Earth
2 september 2022 |
13 min
In the toxic waters of Sulphur Cave in Steamboat Springs, Colo. lives blood-red worm blobs that have attracted scientific interest from around the world. We don special breathing gear and go into the cave with David Steinmann, the spelunking scientist who first documented the worms, along with a trio of science students from Georgia Tech, to collect worms and marvel at the unique crystals and cave formations (ever heard of snottites??) that earned Sulphur Cave a designation as a National Natural Landmark in 2021. Then we learn about how extremophiles like these worms are helping scientists search for new antibiotics, medicines, or in the case of the Georgia Tech team, models for worm blob robots that can explore uneven, dangerous terrain, like caves on other planets.

The Stars That Settled The Great Debate
1 september 2022 |
11 min
It may seem obvious now that other galaxies lie beyond the Milky Way, but less than 100 years ago, some astronomers held a view of our universe that was a little more ... self-centered. In the 1920s, astronomers were locked in the "Great Debate" — whether Earth was center of the universe and if the universe was just the Milky Way. Today, Scientist in Residence Regina G. Barber talks to Dr. Vicky Scowcroft about the stars that ended astronomy's Great Debate.

13 min
In a crater at the top of a dormant volcano lies a place so quiet, the ambient sound is right near the threshold of human hearing. Visitors to the crater say they can hear their own heartbeats. This spot, in Haleakalā National Park, has been nicknamed the "quietest place on Earth."
Getting there is no small feat--the ascent involves hiking upward through five different climate zones. But the reward is an experience of natural silence that is increasingly difficult to find.
Conservationists, park scientists, and communities all over the United States are working to conserve their pristine soundscapes while noise pollution from planes, vehicles, and other human sources increases. Today, Regina G Barber talks with producer Margaret Cirino about the history, culture, and sound of the Haleakalā crater, and why it should matter to all of us.

TASTE BUDDIES: No Sugarcoating How Sweet Affects The Brain
28 juli 2022 |
11 min
Our ancestors evolved the ability to taste the sweet goodness of foods like pastries and creamy chocolates. They were enticed to consume quick calories that might only be available sporadically. What does that mean today for our brains and bodies in a world where sugar is much more abundant? Host Aaron Scott talks to taste and smell researcher Paule Joseph about the sticky science of sugar and how we can have too much of a good thing.

The Accelerated Approvals Process: Are Drugmakers Fulfilling Their Promises?
22 juli 2022 |
13 min
The Food and Drug Administration allows faster drug approvals based on preliminary study data if the drug fulfills an unmet medical need. But the speedy approval comes with a promise that the drugmaker does another clinical trial once the drug is on the market to prove it really works. If not, the FDA can rescind the approval. How are the companies doing and how well does the agency enforce that system?
Pharmaceuticals correspondent Sydney Lupkin investigated the 30-year track record for accelerated approvals. Today, her findings on stalled trials and missing evidence.

Real Life 'Goonies'? A Mysterious Shipwreck Found Off the Oregon Coast
13 juli 2022 |
14 min
For centuries, mysterious blocks of beeswax and Chinese porcelain have washed up on the Oregon coast, leading to legends of pirates, treasure, and a sunken Spanish galleon. It became known as the Beeswax Wreck, and it inspired centuries of treasure hunters—and maybe even Steven Spielberg, as he created The Goonies. Now, researchers have found nearly 330-year-old timbers from the ship in a hard-to-access cave. This is the story of how a team of volunteer archeologists are working to solve one of the most enduring mysteries of the Pacific Northwest, using old-school detective skills and one well-timed natural disaster.

Against All Odds, The Pumpkin Toadlet Is

Being small has its advantages ... and some limitations. One organism that intimately knows the pros and cons of being mini is the pumpkin toadlet.
As an adult, the animal reaches merely the size of the skittle. At that scale, the frog's inner ear is so small, it's not fully functional. That means when the frog moves, it's haphazard and seems kind of drunk. And so today, with the help of Atlantic science writer Katie Wu, we investigate: If a frog can't jump well, is it still a frog?

Historically, the California condor soared across the western skies of North America. But by the 1980s, the bird was on the edge of extinction — just 22 remained.
Thanks to decades of conservation work, the California condor population has rebounded to a couple hundred birds in Central California and Arizona. And this May, a large partnership led by the Yurok Tribe re-introduced the birds to Northern California.
Today, host Aaron Scott talks to Yurok biologist Tiana Williams-Claussen about the years-long quest to return the birds to their ancestral skies, and the importance of condor — who the Yurok call Prey-go-neesh — to the Yurok people and the natural world.

What Research Says About Mass Shootings
1 juni 2022 |
13 min
Parkland, Fla. Buffalo, NY. Uvalde, Texas. Every mass shooting in the U.S. raises calls for better policies to prevent such tragedies. There's evidence suggesting that certain kinds of laws may reduce deaths from mass shootings, say scientists who study the field — but those policy options are not the ones usually discussed in the wake of these events. Furthermore, the amount of resources devoted to studying gun violence is paltry compared to its public health impact.

Telehealth Abortions Are Changing The Culture Of Medicine
31 maj 2022 |
14 min
Recent rule changes have increased access to abortion pills through the mail, using telehealth services. As many U.S. states gear up to restrict abortion access in anticipation of the Supreme Court possibly overturning Roe v. Wade, the medical professionals behind these services are preparing for an even bigger surge in demand. Groups that provide abortion pills are also preparing to face significant new obstacles, as anti-abortion states push back against expanded online access. Both patients and clinicians are testing the boundaries of this service that is fully legal in many states — but operates in a legal gray area in others.

The Turnaway Study: What The Research Says About Abortion
9 maj 2022 |
15 min
A leaked draft opinion in the Supreme Court case Dobbs v. Jackson Women's Health Organization has placed uncertainty on the future of abortion rights in the United States. As written, the opinion would overturn Roe v. Wade protections. We at Short Wave were immediately curious about the data behind abortions: What happens when pregnant people are denied abortions?
For answers, we turned to Dr. Diana Greene Foster, the lead researcher on the interdisciplinary team behind The Turnaway Study. For over a decade, she and her fellow researchers followed just under a thousand women who sought an abortion across 21 states. These data may give us insight into pregnant people's lives in a post Roe v. Wade United States.

The Indicator: How Green Laws Stop Green Projects
21 april 2022 |
10 min
The United States has a goal of net-zero carbon emissions by 2050. Without serious changes to lifestyles, that means dramatic investments in green energy. But environmental laws can actually get in the way.
Today, our colleagues at NPR's daily economics podcast, The Indicator from Planet Money, compare the threats to two bats on opposite ends of the planet. The bats show the tension between local and global environmentalism and how building a green economy is forcing people to have tough conversations about tradeoffs.

Planet Money: How Manatees Got Into Hot Water
12 april 2022 |
22 min
Today we share the mic with our colleagues at Planet Money to talk about one of our favorite aquatic creatures: manatees. Decades ago, manatees nearly went extinct as their habitat dwindled and boats threatened their lives. But power companies noticed something: manatees were hanging out near their power plants, seeking out warm water. So, the power companies teamed up with environmentalists to turn the warm waters near power planets into manatee refuges — saving manatee lives and the power companies money in the process. Now, there's a new conundrum: manatees that are hooked on fossil fuels.

What Octopus Minds May Tell Us About Aliens
1 april 2022 |
14 min
Octopuses! They are escape artists, they camouflage in all kinds of surroundings, and they are incredibly intelligent creatures--and that intelligence evolved completely separately from humans'. That separate evolution makes them the perfect animal to study for Dominic Sivitilli, a PhD candidate in astrobiology and behavioral neuroscience at the University of Washington.
Short Wave co-host Aaron Scott and Oregon Public Broadcasting (OPB) camera person Stephani Gordon visited Dominic's lab to learn about octopus intelligence, and how their arms and suckers can basically think for themselves. Aaron talks to co-host Emily Kwong about how studying octopuses can provide insight into how aliens might think.

Orcas: Apex Predators Or Marine Park Stars?
1 mars 2022 |
14 min
NPR science correspondent Lauren Sommer joins Short Wave host Emily Kwong to talk about a team of researchers who were the first to document a pack of orcas attacking a blue whale. Their work shows that killer whales, while stars in marine parks and movies, are also the ocean's top-- and often vicious-- predators. Humans' complex relationship with them may say more about humans than about the orcas.

Vacuuming DNA Out Of The Air
22 februari 2022 |
13 min
A few years ago, ecologist Elizabeth Clare had an idea--what if she could study rare or endangered animals in the wild without ever having to see or capture them? What if she could learn about them by only pulling data out of thin air? It turns out, the air's not so thin. There are bits of DNA floating around us, and Elizabeth figured out how to collect it. She talks to guest host Lauren Sommer about testing her collection method in a zoo, how another science team simultaneous came up with and tested the same idea and how DNA taken from the environment could revolutionize the field of ecology.

Should Big Oil Pick Up The Climate Change Bill?
2 februari 2022 |
12 min
The Fourth Circuit Court of Appeals is deciding whether a Baltimore case against more than a dozen oil and gas companies will be heard in state or federal court. The city argues the companies are liable for the local costs of climate change. It wants the case heard in state court, which is governed by robust consumer protection laws. But industry lawyers are fighting hard to have it and more than 20 other similar lawsuits nationwide tried in federal court, where the oil and gas industry may be more likely to prevail.
NPR climate correspondent Rebecca Hersher, brings an update on the case, which went before the U.S. Supreme court last year. She explains how this pending decision may prove key to determining who pays for climate change.

Omicron Ebbing Gives Time to Boost Vaccinations
1 februari 2022 |
11 min
As COVID-19 cases in the U.S. drop, the hospitalization rate remains high — as does the death rate. Experts say getting a COVID vaccine booster is key to maintaining immunity, but only about half of all vaccinated people in the U.S. have gotten the booster, which increases protection against both serious illness and death from the Omicron variant. Still, many infectious disease experts are cautiously optimistic for the coming months, pointing to it as a time to bolster our defenses against the virus.

Megadrought fuels debate over whether a flooded canyon should reemerge
26 januari 2022 |

In the 1960s, the Bureau of Reclamation built a dam that flooded a celebrated canyon on the Utah-Arizona border. Today, it's known as Lake Powell — the second-largest reservoir in the U.S.
A half billion dollar tourism industry has grown in the desert around the reservoir but a decades-long megadrought is putting its future in question.
With what some call America's 'lost national park' reemerging, an old debate is also resurfacing: should we restore a beloved canyon or refill a popular and critical reservoir? Environmental and American West correspondent Nathan Rott brings this story to guest host Dan Charles.

The Debate About Pablo Escobar's Hippos
14 januari 2022 |
14 min
Pablo Escobar had a private zoo at his estate in Colombia, with zebras, giraffes, flamingoes - and four hippopotamuses. After Escobar was killed in 1993, most of the animals were relocated except for the so-called "cocaine hippos." Authorities thought they would die but they did not and now, about a hundred roam near the estate. Conservationists are trying to control their population because they worry about the people and the environment. But some locals like the hippos and a few researchers say the animals should be left alone and are filling an ecological void. The controversy reflects growing debate in ecology about what an invasive species actually is.

Man's Best Friend Is Healing Veterans
7 januari 2022 |
15 min
Service dogs have long helped veterans with physical disabilities. While there have been stories about veterans with post-traumatic stress disorder being transformed by service animals, the peer-reviewed science wasn't there to back up the claims. Health reporter Stephanie O'Neill reports that's changed in recent years. Studies suggest service dogs can be effective at easing PTSD symptoms and used alongside other treatments. Now, the PAWS for Veterans Therapy Act will help connect specially trained dogs to some veterans with symptoms of traumatic stress.

An NPR analysis shows that since the vaccine rollout, counties that voted heavily for Donald Trump have had nearly three times the COVID mortality rates of those that voted for Joe Biden. That difference appears to be driven by a partisan divide in vaccination rates. As NPR correspondent Geoff Brumfield reports, political polarization and misinformation are driving a significant share of the deaths in the pandemic.

Using Math To Rethink Gender (encore)

Gender is infused in many aspects of our world — but should that be the case?
According to mathematician Eugenia Cheng, maybe not. In her new book, x+y, she challenges readers to think beyond their ingrained conceptions of gender. Instead, she calls for a new dimension of thinking, characterizing behavior in a way completely removed from considerations of gender.
Cheng argues that at every level — from the interpersonal to the societal — we would benefit from focusing less on gender and more on equitable, inclusive interactions, regardless of a person's gender identity.

Why Aduhelm, a new Alzheimer's treatment, isn't reaching many patients
5 november 2021 |
10 min
Aduhelm, known generically as aducanumab, is the first drug to actually affect the underlying disease process associated with Alzheimer's. Yet sales have been limited, and the drug is reaching very few patients — at least so far. It's expensive, risky and likely doing little to improve patients' lives. NPR science correspondent Jon Hamilton explains why doctors and patients aren't excited about the new drug and what it could mean for future Alzheimer's drugs.

Planning for a space mission to last more than 50 years

In 1977, NASA sent out two Voyager probes to study Jupiter and Saturn. The spacecrafts were designed to last about five years, but they are still, to this day, collecting and sending back data from beyond the solar system. But the Voyager mission is living on borrowed time. Today NPR science correspondent Nell Greenfieldboyce talks about a proposal for an intentionally long mission - what it would take for NASA to actually plan for an interstellar voyage that would pass research and responsibility down through generations.

A new step toward ending 'the wrath of malaria'
2 november 2021 |
11 min
Scientists have been trying to figure out how to eradicate malaria for decades. Globally, a child under the age of five dies from the disease every two minutes, and even for kids who do survive there can be long term complications. A big breakthrough finally came in October when the World Health Organization endorsed MoSQUIRIX, the first malaria vaccine. It has relatively low efficacy, just about 30%, but malaria researcher Winter Okoth explains how the new vaccine could still make a big difference.

An ode to the Pacific lamprey
21 oktober 2021 |
17 min
Pacific lamprey may have lived on Earth for about 450 million years. When humans came along, a deep relationship formed between Pacific lamprey and Native American tribes across the western United States. But in the last few decades, tribal elders noticed that pacific lamprey populations have plummeted, due in part to habitat loss and dams built along the Columbia River. So today, an introduction to Pacific lamprey: its unique biology, cultural legacy in the Pacific Northwest and the people who are fighting to save it.
To learn more about tribal-led efforts to restore the lamprey, read the Tribal Pacific Lamprey Restoration Plan and watch the documentary The Lost Fish.

The United States is on the verge of dramatically expanding the availability of COVID-19 vaccine boosters to shore up people's immune systems. As NPR health correspondent Rob Stein reports, the Food and Drug Administration is poised to authorize the boosters of the Moderna and Johnson & Johnson vaccines. Still, many experts argue boosters aren't needed because the vaccines are working well and it would be unethical to give people in the U.S. extra shots when most of the world is still waiting for their first.

Burnout has long been a problem among health care workers. The pandemic has only made it worse. Some were hopeful COVID vaccines would provide some relief, but that hasn't been the case. Now, health care workers are leaving the industry — and they're taking their expertise with them. Plenty of surveys say that burnout hurts patient care. NPR correspondent Yuki Noguchi spoke to medical workers who agree, the burnout they see on the job means that sometimes patients are not getting what they need.

Scientists Are Racing To Save Sequoias

Based on early estimates, as many as 10,600 large sequoias were killed in last year's Castle Fire — up to 14% of the entire population. The world's largest trees are one of the most fire-adapted to wildfires on the planet. But climate change is making these fires more extreme than sequoias can handle. It's also worsening drought that is killing other conifer trees that then become a tinder box surrounding the sequoias, reports climate correspondent Lauren Sommer. Scientists warn that giant sequoias are running out of time and they're racing to save them.

Managing Wildfire Through Cultural Burns
28 juli 2021 |

Fire has always been part of California's landscape. But long before the vast blazes of recent years, Native American tribes held controlled burns that cleared out underbrush, encouraged new plant growth, and helped manage wildfires. It's a tradition that disappeared with the arrival of Western settlers. NPR climate correspondent Lauren Sommer explains how tribal leaders are trying to restore the practice by partnering up with state officials who are starting to see cultural burns as a way to help bring extreme wildfires under control.

Early in the pandemic, contact tracing was viewed as one of the best options to quell the spread of coronavirus infections.

The past year has been the driest or second driest in most Southwestern U.S. states since record-keeping began in 1895.

'Where We Come From': Emily Kwong's Story

Nearly 1 billion people speak Mandarin Chinese. But Short Wave host Emily Kwong is not among them. As a third generation Chinese American, Emily's heritage language was lost through the years when her father, Christopher Kwong, stopped speaking the language at a young age in order to adjust to life in the U.S. Now, at age 30, Emily's trying to reclaim Chinese by attending virtual Mandarin classes for the first time. In conversation with her father, Emily explores how being 'Chinese enough' gets tied up in language fluency, and how language is a bridge that can be broken and rebuilt between generations — as an act of love and reclamation.

Researchers report in the journal Science that they appear to have some clues about the origin of Earth's plutonium - which has been long debated. Correspondent Nell Greenfieldboyce explains that traces of rare forms of iron and plutonium have been found in extraterrestrial debris that had sunk to the bottom of the Pacific Ocean, hauled up by an oil company, then donated for research. By comparing the iron and the plutonium, scientists found the plutonium was likely forged in a cosmic cataclysm, perhaps a rare kind of supernova, and then rained down on Earth.

Butler was also fascinated by the cyclical nature of history, and often looked to the past when writing about the future. Along with her warnings is her message of hope — a hope conjured by centuries of survival and persistence. For every society that perished in her books, came a story of rebuilding, of repair.

Why 500,000 COVID-19 Deaths May Not Feel Any Different
9 februari 2021 |
11 min
Why is it so hard to feel the difference between 400,000 and 500,000 COVID-19 deaths—and how might that impact our decision making during the pandemic? Psychologist Paul Slovic explains the concept of psychic numbing and how humans can often use emotion, rather than statistics to make decisions about risk.

Should Black People Get Race Adjustments In Kidney Medicine?
13 januari 2021 |
15 min
As the U.S. continues to grapple with systemic racism, some in the medical community are questioning whether the diagnostic tools they use may be contributing to racial health disparities.
As NPR science correspondent Maria Godoy reports, that debate is playing out prominently in the world of kidney medicine — specifically, in the use of estimated glomerular filtration rate, or eGFR. The diagnostic formula most commonly used to assess the health of patients with chronic kidney disease may be unintentionally contributing to poor outcomes — and reinforcing racist thinking.

How Effective Are Antibody Treatments For COVID-19?
7 december 2020 |
12 min
The FDA has issued emergency use authorizations for two monoclonal antibody treatments for COVID-19 – one produced by Eli Lilly and another by Regeneron. As science correspondent Richard Harris explains, emergency use authorization doesn't assure that these new drugs are effective, but that their potential benefits are likely to outweigh the risks. So today, we get to the bottom of how this type of treatment works and if they'll really make a difference.

The CDC Doesn't Know Enough About Coronavirus In Tribal Nations
28 september 2020 |
15 min
A recent CDC report estimates Native Americans and Alaskan Natives are 3.5 times more likely to get COVID-19 than white people, and those under 18 are more likely to test positive.
This report is the first time the federal government has released hard numbers on the coronavirus in tribal nations, but it is most notable for what it does not say about how the virus is affecting Native Americans and Alaskan Natives. And some scientists believe that the CDC's current numbers are an underestimate.
Jourdan Bennett-Begaye, reporter and deputy managing editor of Indian Country Today, explains why the CDC data is so limited in scope — and her efforts to bring more data transparency to the table.

Managing Wildfire Through Cultural Burning
9 september 2020 |
13 min
Fire has always been part of California's landscape. But long before the vast blazes of recent years, Native American tribes held controlled burns that cleared out underbrush, encouraged new plant growth, and helped manage wildfires. It's a tradition that disappeared with the arrival of Western settlers. NPR climate correspondent Lauren Sommer explains how tribal leaders are trying to restore the practice by partnering up with state officials who are starting to see cultural burns as a way to help bring extreme wildfires under control.

Why Shame Is A Bad Public Health Tool — Especially In A Pandemic
24 juli 2020 |
15 min
So much of dealing with the pandemic is about how each of us behaves in public. And it's easy to get mad when we see people not following public health guidelines, especially when it looks like they're having fun.
But Julia Marcus of Harvard Medical School says there are pitfalls to focusing only on what we can see, and more empathetic ways to create new social norms.
Julia's written about that for The Atlantic. Here's some of her recent work.

Understanding Unconscious Bias
15 juli 2020 |
13 min
The human brain can process 11 million bits of information every second. But our conscious minds can handle only 40 to 50 bits of information a second. So our brains sometimes take cognitive shortcuts that can lead to unconscious or implicit bias, with serious consequences for how we perceive and act toward other people. Where does unconscious bias come from? How does it work in the brain and ultimately impact society?

Scientists Think The Coronavirus Transmitted Naturally, Not In A Lab. Here's Why.
6 maj 2020 |
14 min
The Trump administration has advanced the theory the coronavirus began as a lab accident, but scientists who research bat-borne coronaviruses disagree. Speaking with NPR, ten virologists and epidemiologists say the far more likely culprit is zoonotic spillover—transmission of the virus between animals and humans in nature. We explain how zoonotic spillover works and why it's more plausible than a lab accident.

Crows Don't Forget
30 oktober 2019 |
9 min
Crows have gotten a bad rap throughout history. Think about it. A group of them is called a "murder." To get some insight into crows and perhaps set the record straight, we talked to Kaeli Swift. She's a lecturer at the University of Washington and wrote her doctoral thesis on crow "funerals."
In an earlier version of this episode, we used the word "spooky" to describe crows. Because that word has a history of being used as a racial slur, we chose to replace it with the words "scary" and "creepy." Thanks to our listeners who helpfully pointed this out to us, and we apologize. You can learn more about this from our friends at Code Switch.

Adversarial AI
24 oktober 2019 |
10 min
Artificial intelligence might not be as smart as we think. University and military researchers are studying how attackers could hack into AI systems by exploiting how these systems learn. It's known as "adversarial AI." Some of their experiments use seemingly simple techniques. Dina Temple-Raston has been looking into this for her special series, I'll Be Seeing You.

The science is nascent and a little squishy, but researchers like Giulia Poerio are trying to better understand ASMR — a feeling triggered in the brains of some people by whispering, soft tapping, and delicate gestures. She explains how it works, and tells reporter Emily Kwong why slime might be an Internet fad that is, for some, a sensory pleasure-trigger.
