Researchers debate if humidity makes heat more deadly, and finding excess diabetes cases in Ukrainian people that were born right after the 1930s famine
First up this week, which is worse: the heat or the humidity? Staff writer Meredith Wadman joins host Sarah Crespi to talk about conflicting reports on the risk of increased mortality when humidity compounds heat, and how to resolve the debate in the field.
Next, LH Lumey, a professor of epidemiology at the Columbia University Medical Center, discusses what the catastrophe of a famine can teach us about the importance of maternal and fetal health for the long term. His work focuses on records of a 1930s Ukrainian famine painstakingly reconstructed by Ukrainian demographers after being obscured by the former Soviet Union. The famine records combined with newer data show that babies gestated during famine are more likely to acquire type 2 diabetes later in life.

A different source of global warming, signs of a continentwide tradition of human sacrifice, and a virus that attacks the cholera bacteria
First up on the show this week, clearer skies might be accelerating global warming. Staff Writer Paul Voosen joins host Sarah Crespi to discuss how as air pollution is cleaned up, climate models need to consider the decrease in the planet’s reflectivity. Less reflectivity means Earth is absorbing more energy from the Sun and increased temps.
Also from the news team this week, we hear about how bones from across Europe suggest recurring Stone Age ritual killings. Contributing Correspondent Andrew Curry talks about how a method of murder used by the Italian Mafia today may have been used in sacrifices by early farmers, from Poland to the Iberian Peninsula.
Finally, Eric Nelson, an associate professor at the University of Florida’s Emerging Pathogens Institute, joins Sarah to talk about an infectious bacteria that’s fighting on two fronts. The bacterium that causes cholera—Vibrio cholerae—can be killed off with antibiotics but at the same time, it is hunted by a phage virus living inside the human gut. In a paper published in Science, Nelson and colleagues describe how we should think about phage as predator and bacteria as prey, in the savanna of our intestines. The ratio of predator to prey turns out to be important for the course of cholera infections.

Tracing the arrival of rats using bones, isotopes, and a few shipwrecks; and what scientists have learned in 50 years about our famous ancestor Lucy
First on the show: Did rats come over with Christopher Columbus? It turns out, European colonists weren’t alone on their ships when they came to the Americas—they also brought black and brown rats to uninfested shores. Eric Guiry, a researcher in the Trent Environmental Archaeology Lab at Trent University, joins host Sarah Crespi to discuss how tiny slices of bone from early colony sites and sunken shipwrecks can tell us when these pesky rodents arrived.
Next, producer Meagan Cantwell talks with Contributing Correspondent Ann Gibbons about what has happened in the 50 years since anthropologists found Lucy—a likely human ancestor that lived 2.9 million to 3.3 million years ago. Although still likely part of our family tree, her place as a direct ancestor is in question. And over the years, her past has become less lonesome as it has become populated with other contemporaneous hominins.

New clinical trials for treatments of an always fatal brain disease, and what happens with pests when a conventional and organic farm are neighbors
First up on this week’s show, a new treatment to stave off prion disease goes into clinical trials. Prions are misfolded proteins that clump together and chew holes in the brain. The misfolding can be switched on in a number of ways—including infection with a misfolded prion protein from an animal or person. Staff Writer Meredith Wadman talks with host Sarah Crespi about new potential treatments—from antisense nucleotides to small molecules that interfere with protein production—for these fatal neurodegenerative diseases.
Next on the show: Freelance producer Katherine Irving talks with Ashley Larsen, associate professor of agricultural and landscape ecology at the University of California, Santa Barbara, about the effects of organic farms on their neighbors. If there are lots of organic growers together, pesticide use goes down but conventional farms tend to use more pesticides when side by side with organic farms.

On this week’s show: Cheaper launches could make solar power satellites a reality, machine learning helps chemists make small organic molecules, and a book on the extinction of foods
First up on the podcast, space-based solar power gets closer to launch. Staff Writer Daniel Clery talks with host Sarah Crespi about how reusable rockets bring the possibility of giant solar array satellites that beam down gigawatts of uninterrupted power from space.
After that, we hear about small organic molecule synthesis. Making large organic molecules such as proteins and DNA can be a cinch for chemists, but making new smaller organic molecules is tough—partially because optimized general reaction conditions are hard to come by. Nicholas Angello, a graduate research assistant and Department of Defense National Defense Science and Engineering Graduate fellow in the Burke group at the University of Illinois, Urbana-Champaign, talks about an approach that uses robots and machine learning to better optimize these reaction conditions.
Also in the episode: the last in our series of books on food and agriculture. This month, host Angela Saini talks with author Dan Saladino about his book Eating to Extinction: The World’s Rarest Foods and Why We Need to Save Them.

On this week’s show: An analog to the Maunder Minimum, when the Sun’s spots largely disappeared 400 years ago, and measuring the energy it takes to chew gum
We have known about our Sun’s spots for centuries, and tracking this activity over time revealed an 11-year solar cycle with predictable highs and lows. But sometimes these cycles just seem to stop, such as in the Maunder Minimum—a 70-year period from 1645 to 1715 with little or no sunspot activity. News Intern Zack Savitsky joins host Sarah Crespi to discuss a nearby star that appears to have entered a similar quiet period, and what we can learn from it about why stars take naps.
Also this week on the show, Adam van Casteren, a postdoctoral researcher in the School of Biological Sciences at the University of Manchester, joins Sarah to talk about measuring how much energy we use to chew up food. Based on the findings, it appears humans have turned out to be superefficient chewers—at least when it comes to the gum used in the study—with less than 1% of daily energy expenditure being spent on mastication.

On this week’s show: Plans to push a modern space probe beyond the edge of the Solar System, crustaceans that pollinate seaweed, and the latest in our series of author interviews on food, science, and nutrition
After visiting the outer planets in the 1980s, the twin Voyager spacecraft have sent back tantalizing clues about the edge of our Solar System and what lies beyond. Though they may have reached the edge of the Solar System or even passed it, the craft lack the instruments to tell us much about the interstellar medium—the space between the stars. Intern Khafia Choudhary talks with Contributing Correspondent Richard Stone about plans to send a modern space probe outside the Solar System and what could be learned from such a mission.
Next up on the show, Myriam Valero, a population geneticist at the evolutionary biology and ecology of algae research department at Sorbonne University, talks with host Sarah Crespi about how a little crustacean might help fertilize a species of algae. If the seaweed in the study does use a marine pollinator, it suggests there may have been a much earlier evolutionary start for pollination partnerships.
Finally, we have the next in our series on books exploring the science of food and agriculture. This month, host Angela Saini talks with biochemist T. Colin Campbell about his book The Future of Nutrition: An Insider’s Look at the Science, Why We Keep Getting It Wrong, and How to Start Getting It Right.

On this week’s show: The first images from the James Webb Space Telescope hint at the science to come, and disentangling the itch-scratch cycle
After years of delays, the James Webb Space Telescope launched at the end of December 2021. Now, NASA has released a few of the first full-color images captured by the instrument’s enormous mirror. Staff Writer Daniel Clery joins host Sarah Crespi to discuss these first images and what they mean for the future of science from Webb.
Next on the podcast, Jing Feng, principal investigator at the Center for Neurological and Psychiatric Research and Drug Discovery at the Chinese Academy of Sciences’s Shanghai Institute of Materia Medica, discusses his Science Translational Medicine paper on why scratching sometimes triggers itching. It turns out, in cases of chronic itch there can be a miswiring in the skin. Cells that normally detect light touch instead connect with nerve fibers that convey a sensation of itchiness. This miswiring means light touches (such as scratching) are felt as itchiness—contributing to a vicious itch-scratch cycle.
Also this week, in a sponsored segment from Science and the AAAS Custom Publishing Office, Sean Sanders, director and senior editor for the Custom Publishing Office, interviews Paul Bastard, chief resident in the department of pediatrics at the Necker Hospital for Sick Children in Paris and a researcher at the Imagine Institute in Paris and Rockefeller University. They talk about his work to shed light on susceptibility to COVID-19, which recently won him the Michelson Philanthropies & Science Prize for Immunology.

On this week’s show: A shortage of tritium fuel may leave fusion energy with an empty tank, and an attempt to improve police responsiveness to violence against women
First up this week on the podcast, Staff Writer Daniel Clery talks with host Sarah Crespi about a new hurdle for fusion: not enough fuel. After decades of delays, scientists are almost ready to turn on the first fusion reactor that makes more energy than it uses, but the fast-decaying fuel needed to run the reactor is running out.
Also this week, we highlight an intervention aimed at increasing police responsiveness to gender-based violence in India. Sandip Sukhtankar, an economist at the University of Virginia, talks about creating dedicated spaces for women in local police stations, staffed by trained officers. The presence of these “help desks”—when staffed by women officers—increased the recording by police of crimes against women, opening up access to social services and possibly a path to justice.

On this week’s show: Whether biofuels for planes will become a reality, mitigating climate change by working with nature, and the second installment of our book series on the science of food and agriculture
First this week, Science Staff Writer Robert F. Service talks with producer Meagan Cantwell about sustainable aviation fuel, a story included in Science’s special issue on climate change. Researchers have been able to develop this green gas from materials such as municipal garbage and corn stalks. Will it power air travel in the future?
Also in the special issue this week, Nathalie Seddon, a professor of biodiversity at the University of Oxford, chats with host Sarah Crespi about the value of working with nature to support the biodiversity and resilience of our ecosystems. Seddon emphasizes that nature-based solutions alone cannot stop climate change—technological approaches and behavioral changes will also need to be implemented.
Finally, we have the second installment of our series of author interviews on the science of food and agriculture. Host and science journalist Angela Saini talks to Jessica Hernandez, an Indigenous environmental scientist and author of Fresh Banana Leaves: Healing Indigenous Landscapes Through Indigenous Science. Hernandez’s book explores the failures of Western conservationism—and what we can learn about land management from Indigenous people.

On this week’s show: Tracing the roots of Long Covid, and an argument against using the same DNA markers for suspects in law enforcement and in research labs for cell lines
Two years into the pandemic, we’re still uncertain about the impact of Long Covid on the world—and up to 20% of COVID-19 patients might be at risk. First on the podcast this week, Staff Writer Jennifer Couzin-Frankel joins host Sarah Crespi to share a snapshot of the current state of Long Covid research, particularly what researchers think are likely causes.
Also this week, Debra Mathews, assistant director for science programs in the Berman Institute of Bioethics and associate professor of genetic medicine at Johns Hopkins University, talks with Sarah about why everyone using the same DNA kits—from FBI to Interpol to research labs—is a bad idea.
Finally, in a sponsored segment from the Science/AAAS Custom Publishing Office, Sean Sanders, director and senior editor for custom publishing, interviews Bobby Soni, chief business officer at the BioInnovation Institute (BII), about what steps scientists can take to successfully commercialize their ideas. This segment is sponsored by BII.

Two decades after it disappeared in nature, the stunning blue Spix’s macaw will be reintroduced to its forest home, and lessons learned from Texas’s major power crisis in 2021
The Spix’s macaw was first described in scientific literature in 1819—200 years later it was basically poached to extinction in the wild. Now, collectors and conservationists are working together to reintroduce captive-bred birds into their natural habitat in northeastern Brazil. Contributing Correspondent Kai Kupferschmidt discusses the recovery of this highly coveted and endangered parrot with host Sarah Crespi.
Also this week, in an interview from the AAAS annual meeting, Meagan Cantwell talks with Varun Rai, Walt and Elspth Rostow professor in the LBJ School of Public Affairs at the University of Texas, Austin, about how to prepare energy grids to weather extreme events and climate change.

On this week’s show: Exploring the historic Maya’s astronomical knowledge and how grasshoppers clone themselves without decreasing their fitness
First this week, Science contributing correspondent Joshua Sokol talks with producer Meagan Cantwell about the historic Maya’s sophisticated astronomical knowledge. In recent decades, researchers have set out to understand how city structures relate to astronomical phenomena and decipher ancient texts. Now, collaboration between Western scholars and living Indigenous people hopes to further illuminate the field.
Also this week, Mike Kearney, a professor at the school of biosciences at the University of Melbourne, chats with host Sarah Crespi about a species of grasshopper that can reproduce asexually. After studying the insect’s genetics, Kearney and his group didn’t find harmful mutations—or traits that made the grasshopper better adapted to its environment than the two species of grasshopper it hybridized from. Kearney and his team suggest this way of reproducing might not be rare because it’s harmful, but because most animal have safeguards in place to prevent asexual reproduction from arising.

What we learned from a seismometer on Mars, why it’s so difficult to understand the relationship between our microbes and our brains, and the first in our series of books on the science of food and agriculture
First up this week, freelance space journalist Jonathan O’Callaghan joins host Sarah Crespi to discuss the retirement of NASA’s Mars InSight lander. After almost 4 years of measuring quakes on the surface of the Red Planet, the lander’s solar panels are getting too dusty to continue providing power. O'Callaghan and Crespi look back at the insights that InSight has given us about Mars’s interior, and they talk about where else in the Solar System it might make sense to place a seismometer.
Also this week, we have a special issue on the body’s microbiome beyond the gut. As part of the special issue, John Cryan, principal investigator at APC Microbiome Ireland, University College Cork, wrote a commentary piece on tightening the connections research has made between microbes and the brain—the steps needed to go from seeing connections to understanding how the microbiome might be tweaked to change what’s happening in the brain.
Finally this week, we have the first installment of our series of author interviews on the science of food and agriculture. In this inaugural segment, host and science journalist Angela Saini talks to Ousmane Badiane, an expert on agricultural policy and development in Africa, and a co-author of Food For All In Africa: Sustainable Intensification for African Farmers, a 2019 book looking at the possibilities and reality of sustainable intensive farming in Africa.

On this week’s show: The shadow of Milky Way’s giant black hole has been seen for the first time, and bottlenose dolphins recognize each other by signature whistles—and tastes
It’s been a few years since the first image of a black hole was published—that of the supermassive black hole at the center of the M87 galaxy came about in 2019. Now, we have a similar image of the black hole at the center of the Milky Way—our very own galaxy. Staff Writer Daniel Clery joins host Sarah Crespi to discuss why these images look so much alike, even though M87’s black hole is 1600 times larger than ours. We also discuss what’s next for the telescope that captured these shots.
Also this week, we take to the seas. Bottlenose dolphins are known to have a “signature whistle” they use to announce their identity to other dolphins. This week in Science Advances, Jason Bruck and colleagues write about how they may also recognize other dolphins through another sense: taste. Jason, an assistant professor in the department of biology at Stephen F. Austin State University, talks with Sarah about what this means for dolphin minds.
In a sponsored segment from the Science/AAAS Custom Publishing Office, Sean Sanders, director and senior editor, interviews Gary Michelson, founder and co-chair of Michelson Philanthropies, about the importance of supporting research in the field of immunology—and where that support should be directed. This segment is sponsored by Michelson Philanthropies.

On this week’s show: Lipid nanoparticles served us well as tiny taxis delivering millions of mRNA vaccines against COVID-19, but they aren’t optimized—yet, and why we might need inflammation to stop chronic pain
The messenger RNA payload of the mRNA vaccines against SARS-CoV-2 is wrapped up in little fatty packets called lipid nanoparticles (LNPs). These fat bubbles were originally designed for something much different—carrying molecules into cells to silence genes. But they were useful and we were in a hurry, so not much was changed about them when they were pressed into service against COVID-19. Science journalist Elie Dolgin talks with host Sarah Crespi about ongoing efforts to improve LNPs as a delivery system for mRNA vaccines and therapeutic treatments.
Next on the show, we hear about “pain chronification.” Have you ever thought about chronic pain? What happens in the body when it heals—no specific thing is broken—but the pain never subsides? Sarah chats with Luda Diatchenko, professor on the faculties of medicine and dentistry at McGill University, about her Science Translational Medicine paper on the need for inflammation to prevent pain chronification.

On this week’s show: Geoscientists eye contenders for where to mark the beginning of the human-dominated geological epoch, and how sunscreen turns into photo toxin
We live in the Anthropocene: an era on our planet that is dominated by human activity to such an extent that the evidence is omnipresent in the soil, air, and even water. But how do we mark the start? Science Staff Writer Paul Voosen talks with host Sarah Crespi about how geoscientists are choosing the one place on Earth that best shows the advent of the Anthropocene, the so-called “golden spike.”
Also this week, Djordje Vuckovic, a Ph.D. candidate in the department of civil and environmental engineering at Stanford University, joins Sarah to talk about how sunscreen threatens coral reefs. Reefs are under a lot of stress these days, from things like warming waters, habitat destruction, and the loss of their fishy friends to voracious fishermen. Another suspected stressor is chemical sunscreens, which drift off swimming tourists. It turns out that common chemicals in sunscreen that protect skin from the Sun are modified by sea anemones and corals into a photo toxin that damages them when exposed to the Sun’s rays.

On this week’s show: How physicists are using quantum sensors to suss out dark matter, how rabies thwarts canine vaccination campaigns, and a kickoff for our new series with authors of books on food, land management, and nutrition science
Dark matter hunters have turned to quantum sensors to find elusive subatomic particles that may exist outside physicists’ standard model. Adrian Cho, a staff writer for Science, joins host Sarah Crespi to give a tour of the latest dark matter particle candidates—and the traps that physicists are setting for them.
Next, we hear from Katie Hampson, a professor in the Institute of Biodiversity, Animal Health & Comparative Medicine at the University of Glasgow, about her work contact tracing rabies in Tanzania. Her group was able to track rabies in a population of 50,000 dogs over 14 years. The massive study gives new insight into how to stop a virus that circulates at superlow levels but keeps popping up, despite vaccine campaigns.
Finally, we launch our 2022 books series on food and agriculture. In six interviews, which will be released monthly for the rest of the year, host and science journalist Angela Saini will speak to authors of recent books on topics from Indigenous land management to foods that are going extinct. This month, Angela talks with Lenore Newman, director of the Food and Agriculture Institute at the University of the Fraser Valley, who helped select the books for the series.

On this week’s show: Saving birds from city lights, and helping astronauts inhabit robots
First up, Science Contributing Correspondent Josh Sokol talks with host Sarah Crespi about the millions of migrating birds killed every year when they slam into buildings—attracted by brightly lit windows. New efforts are underway to predict bird migrations and dim lights along their path, using a bird-forecasting system called .
Next, we hear from Aaron Pereira, a researcher at the German Aerospace Center (DLR) and a guest researcher at the human robot interaction lab at the European Space Agency. He chats with Sarah about his Science Robotics paper on controlling a robot on Earth from the International Space Station and the best way for an astronaut to “immerse” themselves in a rover or make themselves feel like it is an extension of their body.
In a sponsored segment from Science and the AAAS Custom Publishing Office, Sean Sanders, director and senior editor for custom publishing, interviews Alberto Pugliese, professor of medicine, microbiology, and immunology at the University of Miami, about a program he leads to advance research into type 1 diabetes.

On this week’s show: Climate change is killing critical soil organisms in arid regions, and early evidence for the Maya calendar from a site in Guatemala
Staff Writer Elizabeth Pennisi joins host Sarah Crespi to discuss how climate change is affecting “biocrust,” a thin layer of fungi, lichens, and other microbes that sits on top of desert soil, helping retain water and create nutrients for rest of the ecosystem. Recent measurements in Utah suggest the warming climate is causing a decline in the lichen component of biocrust, which is important for adding nitrogen into soils.
Next, Sarah talks with Skidmore College anthropologist Heather Hurst, who directs Guatemala’s San Bartolo-Xultun Regional Archaeological Project, and David Stuart, a professor of art history and director of the Mesoamerica Center at the University of Texas, Austin, about their new Science Advances paper. The study used radiocarbon dating to pin down the age of one of the earliest pieces of the Maya calendar. Found in an archaeological dig in San Bartolo, Guatemala, the character known as “seven deer” (which represents a day in the Maya calendar), was dated to 300 B.C.E. That early appearance challenges what researchers know about the age and origins of the Maya dating system.

On this week’s show: A new measurement of the W boson could challenge physicists’ standard model, and an abundance of marine RNA viruses
Staff Writer Adrian Cho joins host Sarah Crespi to discuss a new threat to the standard model of particle physics—a heavier than expected measurement of a fundamental particle called the W boson. They chat about how this measurement was taken, and what it means if it is right.
Next, Sarah talks about the microscopic denizens of Earth’s oceans with Ahmed Zayed, a research scientist in the department of microbiology at Ohio State University, Columbus. They talk about findings from a global survey of marine RNA viruses. The results double the number of known RNA viruses, suggesting new classifications will be needed to categorize all this viral diversity.

On this week’s show: A journey to the center of the center of the Earth, and what was missing from the first human genome project
Staff Writer Paul Voosen talks with host Sarah Crespi about the many mysteries surrounding the innermost part of our planet—from its surprisingly recent birth to whether it spins faster or slower than the rest of the planet.
Next, Sarah chats with Adam Phillippy about the results from the Telomere-to-Telomere (T2T) Consortium, an effort to create a complete and detailed read of the human genome. Phillippy, a senior investigator and head of the Genome Informatics Section at the National Human Genome Research Institute, explains what we can learn by topping up the human genome with roughly 200 more megabases of genetic information—practically a whole chromosome’s worth of additional sequencing.

On this week’s show: The ins and outs of the first global treaty on plastic pollution, and why the United States has so few Black physicists
First up, Staff Writer Erik Stokstad joins host Sarah Crespi to discuss the world’s first global treaty on plastics pollution–and the many questions that need answers to make it work. Read a related Policy Forum here.
Up next, we hear from some of more than 50 Black physicists interviewed for a special news package in Science about the barriers Black physicists face, and potential models for change drawing on a 2020 report that documents how the percentage of undergraduates physics degrees going to Black students has declined over the past 20 years.
In his excerpt, Willie Rockward, chair and professor of physics at Morgan State University, describes how a study group dubbed the “Black Hole” provided much-needed support for him and four colleagues who were part of the first cohort of Black graduate physics students at the Georgia Institute of Technology.
Next, Fana Mulu-Moore, a physics and astronomy instructor at Aims Community College in Greeley, Colorado, explains her ‘life-changing’ transition from research to teaching, and how it has given her a sense of purpose.

On this week’s show: Ethical concerns rise with an increase in open brain research, and how sharing saliva can be a proxy for the closeness of a relationship
Human brains are protected by our hard skulls, but these bony shields also keep researchers out. With brain surgeries and brain implants on the rise, scientists are getting more chances to explore living brains. Staff Writer Kelly Servick joins host Sarah Crespi to talk about the ethics of doing research on patients undergoing intense medical procedures, and the kinds of research being done.
Also this week, Ashley Thomas, a postdoctoral researcher in the brain and cognitive science department at the Massachusetts Institute of Technology, talks about the meaning behind sharing saliva. Spend any time with a baby lately? Were you in awe—eager to cuddle, kiss, even change a diaper? Or were you slightly horrified by the drool and other fluids seeping out of this new human? Your feelings on the matter might depend on your closeness with the baby and—as Thomas and colleagues write this week in Science—the baby may notice which way you feel.

Some 80 countries around the world add folic acid to their food supply to prevent birth defects that might happen because of a lack of the B vitamin—even among people too early in their pregnancies to know they are pregnant. This year, the United Kingdom decided to add the supplement to white flour. But it took almost 10 years of debate, and no countries in the European Union joined them in the change. Staff Writer Meredith Wadman joins host Sarah Crespi to discuss the ongoing folate debate.
Last year, a highly anticipated tool for dating ancient materials was released: a new updated radiocarbon calibration curve. The curve, which describes how much carbon-14 was in the atmosphere at different times in the past 55,000 years, is essential to figuring out the age of organic materials such as wood or leather. Sarah talks with Tim Heaton, senior lecturer in the School of Mathematics and Statistics at the University of Sheffield, and Edouard Bard, a professor at the College of France, about how the curve was redrawn and what it means, both for archaeology and for our understanding of the processes that create radiocarbon in the first place—like solar flares and Earth’s magnetic fields.

This week we are covering the Science special issue on mass incarceration.
Can a dog find a body? Sometimes. Can a dog indicate a body was in a spot a few months ago, even though it’s not there now? There’s not much scientific evidence to back up such claims. But in the United States, people are being sent to prison based on this type of evidence. Host Sarah Crespi talks with Peter Andrey Smith, a reporter and researcher based in Maine, about the science—or lack thereof—behind dog-sniff evidence.
With 2 million people in jail or prison in the United States, it has become incredibly common to have a close relative behind bars. Sarah talks with Hedwig Lee, a sociologist at Washington University in St. Louis, about the consequences of mass incarceration for families of the incarcerated, from economic to social.

Rich Stone, former international news editor at Science and current senior science editor at the Howard Hughes Medical Institute’s Tangled Bank Studios, joins host Sarah Crespi to talk about concerning levels of fission reactions deep in an inaccessible area of the site of the 1986 Chernobyl nuclear disaster. Though nothing is likely to come of it anytime soon, scientists must decide what—if anything—they should do tamp down reactions in this hard-to-reach place.
Also on this week’s show, Shlomi Kotler, an assistant professor in the department of applied physics at the Hebrew University of Jerusalem, joins Sarah to discuss the quantum entanglement of macroscopic objects. This hallmark of quantum physics has been confined—up until now—to microscopic items like atoms, ions, and photons. But what does it mean that two drums, each the width of a human hair, can be entangled?

On its first day, the new Biden administration announced plans to recalculate the social cost of carbon—a way of estimating the economic toll of greenhouse gases. Staff Writer Paul Voosen and host Sarah Crespi discuss why this value is so important and how it will be determined.
Next up, Alison Barker, a postdoctoral researcher at the Max Delbrück Center for Molecular Medicine, talks with Sarah about the sounds of naked mole-rats. You may already know naked mole-rats are pain and cancer resistant—but did you know these eusocial mammals make little chirps to identify themselves as colony members? Can these learned local dialects make naked mole-rats a new research model for language learning?

Staff Writer Meredith Wadman and host Sarah Crespi discuss what to expect from the two messenger RNA–based vaccines against COVID-19 that have recently released encouraging results from their phase III trials and the short-term side effects some recipients might see on the day of injection.
Sarah also talks with researcher Xing Chen, a project co-leader and postdoctoral scientist at the Netherlands Institute for Neuroscience, about using brain stimulation to restore vision. Researchers have known for about 70 years that electrical stimulation at certain points in the brain can lead to the appearance of a phosphene—a spot of light that appears not because there’s light there, but because of some other stimulation, like pressing on the eyeball. If electrical stimulation can make a little light appear, how about many lights? Can we think about phosphenes as pixels and draw a picture for the brain? How about a moving picture?

Many schools closed in the spring, during the first wave of the coronavirus pandemic. Many opened in the fall. Staff Writer Jennifer Couzin-Frankel joins host Sarah Crespi to talk about what was learned in spring about how coronavirus spreads in schools that might help keep children safe as cases surge once again.
Also this week: What makes leaves fall off deciduous trees when they do—is it the short, cold nights? Or is the timing of so-called “leaf senescence” linked to when spring happens? Sarah talked to Constantin Zohner, a lead scientist at the Institute of Integrative Biology at ETH Zurich, about his tree leaf timing study. Sarah also spoke with commentary author Christy Rollinson, a forest ecologist at the Morton Arboretum, about how important these trees and the timing of their leaf drop is for climate change.

These days about half of the protein the world’s population eats is from seafood. Staff Writer Erik Stokstad joins host Sarah Crespi to talk about how brand-new biotech and old-fashion breeding programs are helping keep up with demand, by expanding where we can farm fish and how fast we can grow them.
Sarah also spoke with Jan Claesen, an assistant professor at the Cleveland Clinic’s Lerner Research Institute, about skin microbes that use their own antibiotic to fight off harmful bacteria. Understanding the microbes native to our skin and the molecules they produce could lead to treatments for skin disorders such as atopic dermatitis and acne.
Finally, in a segment sponsored by MilliporeSigma, Science’s Custom Publishing Director and Senior Editor, Sean Sanders, talks with Timothy Cernak, an Assistant Professor of Medicinal Chemistry and Chemistry at University of Michigan, Ann Arbor, about retrosynthesis—the process of starting with a known chemical final product and figuring out how to make that molecule efficiently from available pieces.

Staff Writer Robert Service talks with host Sarah Crespi about a different approach to COVID-19 testing that might be useful in response to the high numbers of cases in the United States. To break chains of transmission and community spread, the new strategy would replace highly accurate but slow polymerase chain reaction (PCR) tests with cheaper, faster tests that are less accurate but can be administered frequently. Such tests cost between $1 and $3 compared with more than $100 for diagnostic PCR tests and give results in less than 30 minutes instead of days.

Staff Writer Meredith Wadman joins host Sarah Crespi to discuss the risk of the novel coronavirus infection to pregnant women. Early data suggest expectant women are more likely to get severe forms of the infection and require hospitalization. Meredith describes how the biology of pregnancy—such as changes to the maternal immune system and added stress on the heart and lungs—might explain the harsher effects of the virus.
Also this week, Sarah talks with Gianluca Roscioli about his experiments with commercial razor blades and real human hair. By using a scanning electron microscope, he was able to show how something relatively soft like hair is able to damage something 50 times harder like stainless steel.

Science Editor-in-Chief Holden Thorp joins host Sarah Crespi to discuss his editorial on preventing vaccine hesitancy during the coronavirus pandemic. Even before the current crisis, fear of vaccines had become a global problem, with the World Health Organization naming it as one of the top 10 worldwide health threats in 2019. Now, it seems increasingly possible that many people will refuse to get vaccinated. What can public health officials and researchers do to get ahead of this issue?
Also this week, Sarah talks with Science Senior Correspondent Jon Cohen about his story on Chinese scientist Shi Zhengli, the bat researcher at the center of the COVID-19 origins controversy—and why she thinks President Donald Trump owes her an apology.
Finally, Geert Van der Snickt, a professor in the conservation-restoration department at the University of Antwerp, talks with Sarah about his Science Advances paper on a new process for peering into the past of paintings. His team used a combination of techniques to look beneath an overpainting on the Ghent Altarpiece by Hubert and Jan Van Eyck—a pivotal piece that showed the potential of oil paints and even included an early example of painting from an aerial view.

Contributing correspondent Gretchen Vogel talks about what can be learned from schools around the world that have reopened during the coronavirus pandemic. Unfortunately, few systematic studies have been done but observations of outbreaks in schools in places such as France or Israel do offer a few lessons for countries looking to send kids back to school soon. The United Kingdom and Germany have started studies of how the virus spreads in children and at school, but results are months away. In the meantime, Gretchen’s reporting suggests small class sizes, masks, and social distancing among the adults at school are particularly important measures.

Also this week, Sarah talks with Kirstie Thompson, a Ph.D. student in the Georgia Institute of Technology’s Department of Chemistry and Biochemistry, about increasing the efficiency of petroleum processing. If all—or even some—petroleum processing goes heat free, it would mean big energy savings. Around the world, about 1% of all energy use goes to heating up petroleum in order to get useful things such as gas for cars or polymers for plastics. These days, this separation is done through distillation, heating and separating by boiling point. Kirstie describes a heat-free way of getting this separation—by using a special membrane instead.

First up this week, News Intern Rodrigo Pérez-Ortega talks with host Meagan Cantwell about an oasis of biodiversity in the striking blue pools of Cuatro Ciénegas, a basin in northern Mexico. Researchers have published dozens of papers exploring the unique microorganisms that thrive in this area, while at the same time fighting large agricultural industries draining the precious water from the pools.
David Tatnell, a postgraduate researcher at the University of Exeter, talks with host Sarah Crespi about using heat to make sound, a phenomenon known as thermoacoustics. Just like the sound of fire or thunder, sudden changes in temperature can create sound waves. In his team’s paper in Science Advances, Tatnell and colleagues describe a thermoacoustic speaker that uses thin, heated films to make sound. This approach cuts out the crosstalk seen in mechanical speakers and allows for extreme miniaturization of sound production. In the ultrasound range, arrays of thermoacoustic speakers could improve acoustic levitation and ultrasound imaging. In the hearing range, the speakers could be made extremely small, flexible, and even transparent.

Mikkel Sinding, a postdoctoral fellow at Trinity College Dublin, talks sled dog genes with Sarah. After comparing the genomes of modern dogs, Greenland sled dogs, and an ancient dog jaw bone found on a remote Siberian island where dogs may have pulled sleds some 9500 years ago, they found that modern Greenland dogs—which are still used to pull sleds today—have much in common with this ancient Siberian ancestor. Those similarities include genes related to eating high-fat diets and cold-sensing genes previously identified in woolly mammoths.
In this month's book segment, Kiki Sanford talks with Rutger Bregman about his book, Humankind: A Hopeful History which outlines a shift in the thinking of many social scientists to a view of humans as more peaceful than warlike.

Mosquito-borne infections like Zika, dengue, malaria, and chikungunya cause millions of deaths each year. Nicole Culbert and colleges write this week in Science Robotics about a new way to deal with deadly mosquitoes—using drones. The drones are designed to drop hundreds of thousands of sterile male mosquitoes in areas with high risk of mosquito-borne illness. The idea is that sterile male mosquitoes will mate with females and the females then lay infertile eggs, which causes the population to decline. They found this drone-based approach is cheaper and more efficient than other methods of releasing sterile mosquitoes and does not have the problems associated with pesticide-based eradication efforts such as resistance and off-target effects.

Online news editor David Grimm talks with producer Joel Goldberg about the unique challenges of reopening labs amid the coronavirus pandemic. Though the chance to resume research may instill a sense of hope, new policies around physical distancing and access to facilities threaten to derail studies—and even careers. Despite all the uncertainty, the crisis could result in new approaches that ultimately benefit the scientific community, and the world.
Also this week, Joel Podgorski, a senior scientist in the Water Resources and Drinking Water Department at the Swiss Federal Institute of Aquatic Science and Technology, joins host Sarah Crespi to discuss the global threat of arsenic in drinking water. Arsenic is basically present in all rocks in minute amounts. Under the right conditions it can leach into groundwater and poison drinking water. Without a noticeable taste or smell, arsenic contamination can go undetected for years. The paper, published in Science, estimates that more than 100 million people are at risk of drinking arsenic contaminated water and provides a guide for the most important places to test.

This week on the podcast, Contributing Correspondent Lizzie Wade joins host Sarah Crespi to discuss a turning point for one ancient Mesoamerican city: Tikal. On 16 January 378 C.E., the Maya city lost its leader and the replacement may have been a stranger. We know from writings that the new leader wore the garb of another culture—the Teotihuacan—who lived in a giant city 1000 kilometers away. But was this new ruler of a Maya city really from a separate culture? New techniques being used at the Tikal and Teotihuacan sites have revealed conflicting evidence as to whether Teotihuacan really held sway over a much larger region than previously estimated.
Sarah also talks with Rashid Sumaila, professor and Canada research chair in interdisciplinary ocean and fisheries economics at the University of British Columbia, Vancouver’s Institute for the Oceans and Fisheries. You may have heard of illegal fishing being bad for the environment or bad for maintaining fisheries—but as Sumaila and colleagues report this week in Science Advances, the illegal fishing trade is also incredibly costly—with gross revenues of between $8.9 billion and $17.2 billion each year.

News Editor Tim Appenzeller joins Sarah to discuss Science’s 2019 Breakthrough of the Year, some of the contenders for breakthrough, also known as runners-up, and the breakdowns—when science and politics just didn’t seem to mix this year.
Finally, Science books editor Valerie Thompson brings her favorites from the world of science-inflected media. She and Sarah talk about some of the best books reviewed in Science this year, a food extinction book we should have reviewed, a pair of science-centric films, and even an award-winning birding board game.

About one-third of people with epilepsy are treatment resistant. Up until now, epilepsy treatments have focused on taming seizures rather than the source of the disease and for good reason—so many roads lead to epilepsy: traumatic brain injury, extreme fever and infection, and genetic disorders, to name a few. Staff Writer Jennifer Couzin-Frankel talks with host Sarah Crespi about researchers that are turning back the pages on epilepsy, trying to get to the beginning of the story where new treatments might work.
And Sarah also talks with Torsten Neurbert at the Technical University of Denmark’s National Space Institute in Kongens Lyngby about capturing high-altitude “transient luminous events” from the International Space Station (ISS). These lightning-induced bursts of light, color, and occasionally gamma rays were first reported in the 1990s but had only been recorded from the ground or aircraft. With new measurements from the ISS come new insights into the anatomy of lightning.
