Why Melting Ice In Antarctica Is Making Hurricanes Worse In Texas

Ice in Antarctica is melting really quickly because of climate change. That's driving sea level rise around the world, and the water is rising especially fast in the seaside city of Galveston, Texas ? thousands of miles from Antarctica. Why do Antarctica and Texas have this counterintuitive relationship? And what does it mean for a $34 billion effort to protect the city from hurricanes?

What Happens When An Infant Loses Half Their Brain?

Mora Leeb was 9 months old when surgeons removed half her brain. Now 15, she plays soccer and tells jokes. Scientists say Mora is an extreme example of a process known as brain plasticity, which allows a brain to modify its connections to adapt to new circumstances.

Galaxies Are Older Than We Thought ? That's A Big Deal

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.

When Your Body Rejects The Kidney It Needs

In February 2021, pandemic restrictions were just starting to ease in Hawaii, and Leila Mirhaydari was finally able to see her kidney doctor. 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.

Will Artificial Intelligence Help ? Or Hurt ? Medicine?

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

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

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.

Peep The Delightful Science Of Chickens

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!

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

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

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

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

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

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:
- Crits-Christoph et. al (2023), Genetic evidence of susceptible wildlife in SARS-CoV-2 positive samples at the Huanan Wholesale Seafood Market, Wuhan: Analysis and interpretation of data released by the Chinese Center for Disease Control

What we lose if the Great Salt Lake dries up

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'

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!

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?

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

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?

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.

'Are You A Model?': Crickets Are So Hot Right Now

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

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.

Rome wasn't built in a day, but they sure had strong concrete

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.

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.
