A program trains women as tactile medical examiners to identify tumors before they show up on imaging scans. And, in a materials science discovery, scientists made a liquid silk solution that hardens and picks up objects—not unlike Spider-Man's web.How Blind Women In India Are Detecting Early Breast CancerBreast cancer is the second most common cancer worldwide, just behind lung cancer. And the earlier a breast tumor is found, the more likely it is that the person survives their diagnosis.An international program called Discovering Hands trains blind women to detect even the smallest lumps and bumps through breast exams. The idea is to leverage the blind examiners' sense of touch, which may be more acute than sighted people's, to feel for breast abnormalities and, hopefully, catch cancer in an early stage.Discovering Hands has a cohort in India, a country where only around one in every two people diagnosed with breast cancer survive, and imaging equipment can be expensive or hard to come by.SciFri producer Rasha Aridi talks with science journalist Kamala Thiagarajan, who reported on Discovering Hands' program in India for NPR's global health blog, Goats and Soda.Accidental Breakthrough Makes Web-Slinging Silk A RealityWe're all familiar with Spider-Man—the red-suited hero who swings through New York using spider silk that shoots from his hands. While Peter Parker has a radioactive spider to thank for his shooting webs, scientists at Tufts University have made their own version of liquid silk that solidifies and can pick up objects.This discovery was made accidentally, says biomedical engineer Dr. Marco Lo Presti of the Tufts University Silklab. Lo Presti found that combining silk from a silkworm with dopamine and acetone made the silk change from a flexible liquid to a hardened fiber that attaches to objects.Lo Presti joins guest host Kathleen Davis to talk about the possibilities of liquid silk adhesives, and the advancements he'd like to see to make the technology better.Transcripts for each segment will be available after the show airs on sciencefriday.com.

Sitting is a big part of modern life. Many people work at a desk all day, have long commutes, or at least enjoy some time relaxing on the couch at the end of the day. But sitting has gained a reputation as being bad for us—with some going so far as to call it “the new smoking.”A recent study in the journal PLOS One sheds more light on just how much sitting is too much, using a cohort of more than 1,000 young adults, including 730 twins. The results showed that sitting for more than about eight and a half hours per day is linked to a higher total cholesterol and body mass index than sitting for less than that amount of time.But there's good news: 30 minutes of vigorous exercise per day may counter the negative effects that come from long days of sitting.Joining guest host Kathleen Davis to discuss the findings are two of the study authors: Dr. Chandra Reynolds, professor in the Institute of Behavioral Genetics at the University of Colorado, Boulder; and Ryan Bruellman, PhD candidate in genetics, genomics, and bioinformatics at the University of California, Riverside.Transcripts for each segment will be available after the show airs on sciencefriday.com.  Subscribe to this podcast.

The Accidental Discovery That Gave Us ‘Forever Chemicals'When it comes to PFAS chemicals—known as “forever chemicals”—we often hear that they're used in nonstick coatings, flame retardants, and stain repellants. But those examples can hide the truth of just how widespread their use has been in modern life.A new season of the “Hazard NJ” podcast looks at the origin story of PFAS chemicals, and the accidental discovery of PTFE—aka Teflon—in a DuPont laboratory in southern New Jersey. “Hazard NJ” host Jordan Gass-Pooré joins guest host Kathleen Davis to talk about the history of PFAS, their effect on the environment and health of New Jersey residents, and work towards cleaning up the PFAS mess.A Play About Pregnancy Inspired By Mushroom ResearchPeople are finding all sorts of uses for mushrooms these days, but we're going to focus on two of them: how scientists are using them in robots and how playwrights are using them in theater. A few weeks ago, SciFri producer and host of our “Universe of Art” podcast D Peterschmidt moderated a panel at the Science In Theater Festival in Brooklyn, New York.The festival is put on by a company called Transforma Theatre that stages science-inspired plays. Each year, they pair playwrights with scientists to make short plays that explore the research focus of the scientist.Director and playwright Hannah Simms was paired with Dr. Andrew Adamatzky, a professor of unconventional computing, who's learning how to connect various parts of nature, like mushrooms, to computers, and consulted with Hannah during the writing process. The play, called “Fruiting Body,” is about a fungal-computing scientist who, while pregnant, creates a fetal heart monitor powered by mycelium, which turns out to be sentient. While the concept is definitely science fiction, it is based on real unconventional mushroom research.D talks with Hannah to learn why she wanted to explore her pregnancy through the lens of mushroom research. They're also joined by Dr. Anand Mishra, a research associate at Cornell University's department  of mechanical and aerospace engineering, who explains how he helped build a robot that's powered by king oyster mushroom mycelium.Transcript for this segment will be available after the show airs on sciencefriday.com.

“The Burning Earth” examines over 800 years of history to demonstrate how violence against people and the planet are one and the same. Also, the host of the “Hazard NJ” podcast talks about the origins of PFAS “forever chemicals” and their impact on New Jersey residents.How Empire and Environmental Destruction Go Hand-In-HandA new book called The Burning Earth: A History takes on a massive question: How did we get here? “Here” being this point in environmental history and decades deep into the climate crisis. Over the span of 800 years of history, the book connects the dots of how the pursuit of empire, environmental destruction, and human migration led us to this moment in time.SciFri producer Kathleen Davis talks with author Dr. Sunil Amrith, a historian at Yale University. They discuss some common threads that run through human and environmental history, why peace has to be a part of climate action, and what we can learn from understanding the past.Transcripts for each segment will be available after the show airs on sciencefriday.com.

The effect, known as the Hubble Tension, has been confirmed by James Webb Space Telescope observations. Also, despite near daily warnings of food recalls, 2024 hasn't been that different from previous years.The Universe Is Expanding Faster Than ExpectedThere's still a lot to be learned about the physics of our universe—and one of the most perplexing ideas is something called the Hubble Tension. That's an observation, made around a decade ago, that the universe seems to be expanding faster than it should be according to cosmologists' understanding of its earliest days. Now, two years of James Webb Space Telescope observations of supernovae have confirmed those previous measurements made by the Hubble telescope, meaning that the puzzle isn't just due to some instrumental error.Casey Crownhart, climate reporter at MIT Technology Review, joins Kathleen Davis to talk about that finding and other stories from the week in science, including a new quantum computing chip from Google, efforts to improve electrical control of prosthetics, proposed new protections for monarch butterflies, and more.Are Food Recalls Actually On The Rise? Not Really.It feels like there's been an onslaught of food recalls this year. The Food and Drug Administration and the Department of Agriculture have issued recalls for items like cucumbers and carrots, deli meat and smoked salmon, which have been contaminated with pathogens like salmonella, E. coli, and listeria.There were just over 1,900 food recalls in the fiscal year ending in October 2024. While that number has been increasing since an initial dip in recalls early in the COVID-19 pandemic, it's still lower than the numbers seen in the several years before the pandemic.SciFri producer Kathleen Davis talks with Dr. Byron Chaves, food scientist and professor at the University of Nebraska-Lincoln, about why it feels like there are so many food recalls this year, how a recall happens, and what food safety tips you should know as a consumer.Transcripts for each segment will be available after the show airs on sciencefriday.com.

Just in time for Thanksgiving, a potato researcher explains potato varieties, potato nutrition, and some tubular tuber facts. And, irregular, fatty marbling gives meat a unique texture. Recreating that in plant-based products isn't easy.A Horn Of Potato PlentyThe potato is a versatile vegetable—baked, roasted, fried, mashed—it can bring something to just about any menu. But, how exactly do these tasty tubers end up on our tables? We'll give you a crash course in potato science, including how potatoes are grown (hint: not from seeds!) and what scientists look for when they develop new potato varieties.SciFri producer Kathleen Davis talks with Dr. Rhett Spear, assistant professor in the Plant Sciences Department at the University of Idaho. Adding Marbling To Fake Meat For That Extra-Realistic BitePlant-based meat products have evolved over the past few decades. You can find them in many forms, like sausages, deli meats, and faux chicken nuggets. During the holiday season, no plant-based meat is more famous than the Tofurky Roast, a round imitation turkey.Despite improvements in flavor for plant-based meat products, there are still lots of challenges to getting fake meats to mimic their real counterparts. One tough one is textural: instilling a marbling effect. This is the effect of irregular fat deposits, which occur naturally in animal meat.Plant-based meat has a uniform texture by design. Because each product is processed to be a certain way, the randomness and irregularity of fat pockets is taken out of the equation. But some food scientists are working on adding more of this meaty texture to plant-based meat.Joining guest host Kathleen Davis to discuss the challenges and possibilities for the next stage of plant-based meat is Dr. David Julian McClements, distinguished professor in food science at the University of Massachusetts Amherst.Transcripts for each segment will be available after the show airs on sciencefriday.com.

We recently asked our listeners which dubious health claims they've been seeing in their social media feeds or being circulated by friends and family. Unsurprisingly, we received a ton of questions about nutrition, including: Is seed oil bad for you? Does apple cider vinegar really lower blood sugar? What is the difference between processed and ultraprocessed foods? To answer those questions and more, SciFri producer Kathleen Davis talks with RDN Jessica Clifford, a nutrition specialist at Department of Food Science and Human Nutrition at Colorado State University. Transcripts for each segment will be available after the show airs on sciencefriday.com.

Fifty-three days after Hurricane Helene, residents of Asheville can safely drink their tap water without boiling it. Why did it take so long? And, tribes' historic lands on the Gulf Coast are being lost to the sea. To slow it down, one tribe has turned to oyster shells.The Struggle To Restore Drinking Water After Hurricane HeleneWhen Hurricane Helene barrelled through the southeastern US in September, it dumped an estimated 40 trillion gallons of water on the region. That resulted in immense flooding that destroyed roads, buildings, power lines, and other infrastructure.And it also impacted the region's potable water supply. For weeks, residents in Asheville, North Carolina, didn't have access to clean drinking water because the extensive flooding washed large amounts of sediment into the local reservoir. As of Monday, limited access to potable water was restored, marking the first time in 53 days that local residents didn't have to boil tap water to drink it.Before that access was restored, we heard from listeners Sarah and Alison in Asheville who had their own questions about the water quality in their city, and the science behind sediment issues in a local reservoir.Guest host and SciFri producer Kathleen Davis is joined by Dr. Sarah Ledford, associate professor of geosciences at Georgia State University, to figure out why it can take so long for cities to clean their potable water after a storm like this and what other regions expect from the aftermath of future extreme weather.Using Oyster Shell Reefs To Counter Sea Level Rise In LouisianaOn a hot Friday morning, the sun beat down on volunteers gathered at the edge of the water in southern Plaquemines Parish. They passed heavy sacks of oyster shells to each other down a line. The volunteers loaded the shells onto boats to use them for building an oyster reef to help slow land loss in Grand Bayou Indian Village.“The oyster reef is a living thing. Baby oysters are going to attach to it. It's going to grow. It's going to become bigger,” said James Karst with the Coalition for Coastal Louisiana, the organization that built the reef. “But when the sea level rises, because oysters are growing on it, it will grow vertically as well, so it will continue to add protection.”Louisiana's land loss is an existential crisis for many of the tribes who live along the coast. Grand Bayou Indian Village, a small community, home to the Atakapa-Ishak/Chawasha tribe, is watching its lands wash away. Nearly 1,000 people lived in the village in the 1940s, but now there are only about a dozen homes raised on stilts right along the edge of the bayou. Boats are the only way to get around.“You can look at the GPS and it will indicate a different color for where land is,” said Karst. “You'll be looking at this on the screen, then you'll look up and there is no land there. It's just open water.”Volunteers built the reef by stacking bags of recycled oyster shells in the water, up and down the shoreline. The shells came from restaurants in New Orleans. The coalition recently expanded its oyster recycling services to Baton Rouge.Read the full story at sciencefriday.com.Transcripts for each segment will be available after the show airs on sciencefriday.com.

On November 24, 1974—50 years ago this November—a pair of paleoanthropologists made the discovery of a lifetime: a set of 47 bones, hidden in the dusty, rocky hills of a fossil site in Hadar, Ethiopia. The skeleton belonged to a 3.2 million year old hominin, which came to be nicknamed Lucy.She marked the very first specimen of Australopithecus afarensis—a species of early hominins that were very likely our own ancestors. Lucy might be the most famous fossil in the world, and she's transformed our understanding of human evolution.SciFri's Kathleen Davis looks back at 50 years of Lucy with the people who know her best: Dr. Donald Johanson, founding director of the Institute of Human Origins at Arizona State University and the paleo legend who discovered her, as well as Dr. Zeray Alemseged, paleoanthropologist at the University of Chicago who discovered “Lucy's baby.” They discuss what Lucy has taught us in the last 50 years, why she remains a scientific icon, and how understanding our ancestral origins helps us understand humanity.Transcripts for each segment will be available after the show airs on sciencefriday.com.

This was the sixth test launch of the Starship vehicle, which could eventually carry humans and cargo to the moon. It was extremely loud. Also, divers have recovered seeds of a long-lost rye variety from a 146-year-old shipwreck in Lake Huron. Scientists hope to bring it back to life.SpaceX's Starship Completes In-Orbit Engine TestOn Tuesday, the rocket company SpaceX conducted another test flight of its Starship spacecraft. In the uncrewed mission, the sixth test of the system, the company was seeking to test its ability to restart the Starship engines while in orbit, a function that's necessary for in-space maneuvering. The rocket did launch successfully, and the engine test worked. However, at the last minute the company elected not to try to repeat an October maneuver in which it caught a returning SuperHeavy rocket booster at the launch tower, citing safety concerns.SciFri's Charles Bergquist joins guest host Kathleen Davis to talk about the launch, and related research into the tremendous sound created by the system's launch and reentry. They also discuss other stories from the week in science, including the discovery of a saber-toothed kitten in Siberian permafrost, efforts to use light to help destroy PFAS chemicals, a company using Pokemon Go game data to train an AI, and more.Michigan-Based Team To Resuscitate Shipwrecked Rye SeedsIn 1878, a wooden schooner named the James R. Bentley set sail from Chicago to Buffalo, New York. But strong winds and rough waters damaged the ship, and it sank to the bottom of Lake Huron. The crew was saved, but the ship's cargo—a large shipment of rye—sank with it. In the years since the shipwreck, that particular variety of rye has faded out of existence.Now, almost 150 years later, a Michigan-based team is trying to bring the long-lost rye back to life. They dove to the shipwreck, retrieved a tube full of seeds, and are planning to use gene technology to recreate the rye variety. Their goal is to encourage farmers to grow it, so that distillers can use it to make whiskey.SciFri producer Kathleen Davis talks with Dr. Eric Olson, professor of wheat breeding and genetics at Michigan State University, and Chad Munger, founder and CEO of Mammoth Distilling.Transcripts for each segment will be available after the show airs on sciencefriday.com.

Throughout history, humans have given a lot of thought to death. We've grappled with our mortality, created elaborate burial rituals, and contemplated how best to mourn the loss of a loved one.But what about other animals? How do they understand death? Scientists have begun looking at this question more closely in the last two decades.For example, chimpanzees have a wide variety of responses to death based in part on their relationship with the deceased. Possums put on elaborate displays to fake their own deaths. Ants can tell another ant is dead by the chemicals it omits, but have no concept of what death actually means.SciFri producer Kathleen Davis talks with Dr. Susana Monsó, associate professor of philosophy at the National Distance Education University in Spain and author of Playing Possum: How Animals Understand Death.Transcript for this segment will be available after the show airs on sciencefriday.com.

Pregnancy is a hugely transformative experience, both in how it can change someone's day-to-day life, and how it affects the body. There's a key part of the body that's been under-researched in relation to pregnancy: the brain.Those who have been pregnant often talk about “pregnancy brain,” the experience of brain fog or forgetfulness during and after pregnancy. There's also the specter of postpartum depression, a condition that affects about 1 in 7 women post-birthing. There's still a dearth of information about what causes these cognitive, psychological, and emotional experiences.In a recent study, scientists took MRI scans of participants before, during, and after pregnancy, and spotted distinctive changes in the brain's gray and white matter. While these anatomical changes are noticeable, the researchers are still trying to determine what they actually mean for behavior. Joining guest host Kathleen Davis to talk about this study is Dr. Liz Chrastil, associate professor of neurobiology and behavior at the University of California Irvine.Transcripts for each segment will be available after the show airs on sciencefriday.com.

On October 14, NASA launched Europa Clipper, its largest planetary mission spacecraft yet. It's headed to Jupiter's icy moon Europa, which could have a giant ocean of liquid water hidden under its icy crust. And where there's water, scientists think there may be evidence of life. The spacecraft is equipped with nine different instruments and will complete nearly 50 flybys of Europa, scanning almost the entire moon.SciFri producer Kathleen Davis talks with Dr. Padi Boyd, NASA astrophysicist and host of the agency's podcast “Curious Universe,” about the launch and the excitement at NASA. Then, Ira checks in with two scientists who are working on the mission about what they're excited to learn: Dr. Ingrid Daubar, planetary scientist at Brown University and a Europa Clipper project staff scientist at NASA's Jet Propulsion Laboratory; and Dr. Tracy Becker, planetary scientist at Southwest Research Institute and a deputy principal investigator for the ultraviolet spectrograph on the Europa spacecraft.Transcript for this segment will be available after the show airs on sciencefriday.com.

The heaviest antimatter nucleus to date was spotted in a particle accelerator. It could provide new insights into the nature of matter. And, research indicates different songbird species might intentionally travel together during migration, giving each other a possible boost in survival.Physicists Create Heaviest Antimatter Nucleus YetAntimatter is one of science's great mysteries. It is produced all around us for fractions of a second, until it collides with matter, and the particles annihilate one another. But what is it?Antimatter is just like matter, except for one thing. Its particles have the same mass as ordinary matter, but an opposite charge. For example, an electron has a negative charge, so an anti-electron—called a positron—weighs the same, but has a positive charge.Antimatter is a natural product of some types of radioactive decay and cosmic ray collisions, but it can also be made in particle colliders here on Earth. But making antimatter particles this way is difficult and expensive—let alone controlling them enough to create an entire anti-atom. NASA estimates that creating a gram of antimatter would cost about $62.5 trillion.But why does antimatter matter? It may hold the key to understanding one of the universe's biggest mysteries: why there's something rather than nothing. Cosmologists say that during the Big Bang, matter and antimatter should have been created in equal amounts. But everything around us today is mostly matter, meaning either that there was an excess of matter created, or that matter and antimatter don't quite follow the rules physicists expect.Recently, scientists at Brookhaven National Laboratory's Relativistic Heavy Ion Collider spotted 16 instances of the heaviest exotic antimatter nucleus observed to date: antihyperhydrogen-4.To explore what this breakthrough means for antimatter research, SciFri producer Charles Bergquist talks to Dr. Jamie Dunlop, associate department chair for nuclear physics at Brookhaven National Laboratory.Different Bird Species May Team Up For MigrationThis season, billions of birds will take to the skies as they flock to their wintering grounds. With so many different species on the move, they're bound to run into each other. A new study in the journal Proceedings of the National Academy of Sciences suggests that this mixing and mingling might not be coincidental.In fact, different bird species could have their own social networks that might boost each others' survival.SciFri producer Kathleen Davis talks with lead author Dr. Joely DeSimone, migration ecologist at the University of Maryland Center for Environmental Science Appalachian Laboratory, about untangling avian relationships.Transcripts for each segment will be available after the show airs on sciencefriday.com.

SciFri producer Kathleen Davis talks with Dr. Kizzmekia Corbett-Helaire, assistant professor of immunology and infectious diseases at Harvard's T.H. Chan School of Public Health to help answer our listeners' top questions about the updated COVID-19 vaccines.This Q&A, which includes questions from our audience members, has been adapted from our interview with Dr. Kizzmekia Corbett-Helaire. It has been edited for clarity and brevity.If I've already had COVID and it wasn't so bad, why should I even bother with this new booster?There's always a chance that COVID-19 will cause more than the sniffles, or that you could end up in the emergency room—especially for older people. Why take that chance when you have the option to go to your local CVS and, in many cases, get a free vaccine that has been proven to decrease your chances of more severe disease?My hope is that as time progresses, people become more comfortable with the idea of getting seasonal vaccinations for COVID-19 along with flu.  Is the new COVID-19 vaccine one shot?Yes.Read the full Q&A at sciencefriday.com.Transcripts for each segment will be available after the show airs on sciencefriday.com.

Octopus mating behaviors can be quite deadly. Many species are cannibalistic, making the entire prospect of mating dangerous, and female octopuses often die after laying one clutch of eggs. Their cannibalistic tendencies mean that octopuses don't socialize as much as other animals.But the larger Pacific striped octopus (LPSO) is different. For one, they live together in colonies. And mating is not only a safer proposition, it involves beak-to-beak “kissing.” Plus, females can lay eggs repeatedly, even tending to embryos at various stages of development.But because these behaviors are so uncharacteristic of most octopuses, the scientific community didn't officially recognize their existence until 2015, despite the decades-long effort of a Panamanian diver and artist named Arcadio Rodaniche. When he tried to share his findings about the LPSO at a symposium and publish them in a journal, he was flatly rejected. But his persistent research and documentation of the species would eventually be validated when researchers were able to obtain and observe the octopuses in captivity.SciFri producer Kathleen Davis sits down with freelance science writer Kenna Hughes-Castleberry to talk about an article she reported for Science Friday about the late Rodaniche and his yearslong effort to get official scientific recognition for the LPSO.An illustration of a larger Pacific striped octopus by Arcadio Rodaniche.

Kids and teens are back in school, and the battle over the smartphones in their pockets is becoming more prominent. For years, teachers and parents have lamented about the distractions these devices cause in and out of the classroom. Last year, the US surgeon general declared a youth mental health crisis, citing social media as a significant factor, and more than 40 US states are suing Meta, owner of Facebook and Instagram, arguing that the company intentionally manipulated their apps to addict teens and kids.A 2021 survey showed that 76% of US public schools prohibit cellphones. Seven states have implemented bans, and 14 more recently introduced similar legislation.To parents and educators, it might seem that phones and social media are bad for kids and bad for learning. But research shows that the reality is more complicated, with some suggesting that a blanket smartphone ban isn't necessarily the solution.So what are the best ways to approach school phone bans? What do we know about the psychological effects of smartphones on kids and teens? And why does this research tend to defy simple answers?To answer these questions, guest host and SciFri producer Kathleen Davis is joined by Dr. Emily Weinstein, co-director of the Center for Digital Thriving at Harvard University, and the author of Behind Their Screens: What Teens Are Facing (And Adults Are Missing), and Sandy Roberts, education program manager at Science Friday and former middle school teacher.Transcripts for each segment will be available after the show airs on sciencefriday.com.

SpaceX Crew Completes First Citizen SpacewalkBig news in the world of commercial space flight: On Thursday morning, Jared Iasaacman and Sarah Gillis, members of SpaceX's Polaris Dawn mission, became the first civilians to complete a spacewalk. The mission is a collaboration between Elon Musk's SpaceX and Isaacman, a billionaire tech entrepreneur. While outside the spacecraft, the two crew members conducted mobility tests on their spacesuits.SciFri Producer Kathleen Davis talks with Jason Dinh, climate editor at Atmos Magazine about this and other top science news of the week including deadly cholera outbreaks, germs at 10,000 ft, and Japanese eels that can escape a fish stomach through their gills.The First Successful Whole-Eye Transplant, Over A Year LaterIn May of 2023, there was a massive advance in the world of organ transplantation: the first whole human eye and partial face transplant. The man at the center of this procedure is 46-year-old Aaron James, who sustained significant facial injuries from a high-voltage work accident.At the time, it was unclear just how successful the operation would be. Previous tests in animals had resulted in shrinkage of the transplanted eye, if not outright rejection. But now, more than a year after the transplant, a new paper in the journal JAMA outlines the success of this first-of-its-kind operation. While James cannot see out of his new eye, there is blood flow, normal pressure, and a retinal response to light.Guest host Kathleen Davis speaks with Dr. Daniel Ceradini, director of research at NYU Langone's Department of Plastic Surgery and first author of the JAMA study. They discuss the implications this success could have for the future of eye surgery, and the dramatic improvements in James' quality of life.Transcripts for each segment will be available after the show airs on sciencefriday.com.

On July 17, Apex the stegosaurus was sold at Sothebys in New York City for a record $44.6 million. The buyer was billionaire Ken Griffin, CEO of the hedge fund Citadel, who says he plans to loan the fossil to American institutions for display.But despite Griffin's statement, some paleontologists aren't too happy about the trend of fossils going up for auction.The sale of dinosaur fossils has become more and more profitable in recent years. Eight out of the ten most expensive fossils have been sold in the last four years. This trend of rising sale prices leaves museums and research institutions unable to pay for fossils that could benefit paleontological research.Paleontologists fear that as more and more fossils become privately owned, the availability of fossils for research and even access to dig sites might decrease or be restricted.SciFri guest host and producer Kathleen Davis is joined by Dr. Steve Brusatte, professor of paleontology at the University of Edinburgh in Scotland to talk about the potential scientific impacts of privatizing and selling fossils.Transcript for this segment will be available after the show airs on sciencefriday.com.

The University of Hawaiʻi study will be the largest of its kind to investigate the health and social impacts of the Maui wildfires. Also, fiberglass is washing up on Nantucket's shores, and residents are concerned about the long-term environmental impact of this debris.Hawaiʻi Wildfire Survivors To Join Long-Term Health StudyNearly a year ago, Maui experienced a series of wildfires that caused major destruction and anguish for residents. More than 100 people died and thousands of structures were destroyed in what was the fifth deadliest wildland fire in U.S. history.Survivors of those fires are now taking part in the largest study of its kind to understand the health and social impacts of the Maui wildfires. The research team will sample the blood, DNA, and urine of participants over at least a decade to see if they develop conditions such as cancer. Researchers say this information will be essential as the island and its residents continue to recover.Casey Crownhart, climate reporter for the MIT Technology Review joins guest host Kathleen Davis to talk about this story and other top science news of the week, including California's Park Fire.Damaged Wind Turbine Blade Sinks Off Massachusetts CoastA large piece of fiberglass debris from the damaged Vineyard Wind turbine blade has sunk to the ocean floor, as the debris cleanup continues, according to press release from the town of Nantucket that's timestamped for 9:10 a.m.Town officials said that about half of the fiberglass shell of the blade remains attached and crews will continue to monitor it until a removal plan is developed. Most of the green and white foam fill dislodged during the initial failure last Saturday.They added that Vineyard wind is also developing a plan to test water quality around the island.“This complex undertaking involves engaging experts to determine the best path forward. To conduct the testing, specific information from GE's Safety Data Sheets is required, which is expected to be delivered to Vineyard Wind today,” according to the press release.To read the full story, visit our website. Transcripts for each segment will be available after the show airs on sciencefriday.com.

The gut microbiome is an important ecosystem of microbes that lives in each one of us, and its strength affects our overall health.However, the small intestine is an underappreciated part of the gut microbiome. Most of the research into our microbiomes has focused on the other end of the gastrointestinal tract, namely, the colon. And poop samples are an easy way to analyze the microbiome in that lower part of the gut.Better understanding microbiome disruptions in the small intestines may allow researchers to better understand disorders like irritable bowel syndrome, and celiac disease. Dr. Christopher Damman, associate professor of gastroenterology at the University of Washington, gives SciFri producer Kathleen Davis a crash course in the microbiome of the small intestine.Transcripts for each segment will be available after the show airs on sciencefriday.com.

As the James Webb Space Telescope marks two years of operations, NASA unveils a new image of two galaxies interacting. And, new research shows that cats' tendency to scratch is affected by stress, certain kinds of play, and how active they are at night.Galaxies ‘Dance' In Stunning New JWST ImageThe James Webb Space Telescope, the most powerful telescope created by humans, has been successfully operating in space for two years now. Since its launch, the telescope has dazzled astronomers and the public with new kinds of scientific data about the universe and with stunning, highly detailed pictures. And on its two-year anniversary, the telescope continues to return impressive visuals: NASA released a mesmerizing image today of two intermingling galaxies nicknamed the Penguin and the Egg.Jason Dinh, climate editor at Atmos, joins guest host Kathleen Davis to talk about that and other top science stories of the week, including a new study that shows that children with autism have a unique microbiome, new FEMA rules that factor in climate change when rebuilding in flood-prone areas, and how invasive insects use hitchhiking to spread their populations.Why Some Cats Scratch Furniture So MuchIf you have a cat, you've probably endured your fair share of unwanted furniture scratching. Maybe you've purchased scratching posts, rearranged your furniture, or played with your cats before bed, to try to prevent it. And yet, you wake up to shredded upholstery or bedding.Furniture scratching is often a stress response, and cats who live with kids or are more playful and active at night are more likely to scratch.SciFri producer Kathleen Davis spoke with Dr. Yasemin Salgirli Demirbas, a physiology professor at Ankara University in Turkey and visiting fellow at the Atlantic Veterinary College at the University of Prince Edward Island, about her recently published study which tracked why some cats are more prone to scratching destruction than others and explored the best way for cat owners to achieve a mostly intact living room.Transcripts for each segment will be available after the show airs on sciencefriday.com.

The larger Pacific striped octopus is unusually social. But it wasn't recognized by scientists until 2015, despite one man's efforts. And, a deep-sea squid in the family Gonatidae was filmed cradling large eggs for its body size, which suggests it's an entirely new species.Why It Took Decades For This Octopus To Be RecognizedOctopus mating behaviors can be quite deadly. Many species are cannibalistic, making the entire prospect of mating dangerous, and female octopuses often die after laying one clutch of eggs. Their cannibalistic tendencies mean that octopuses don't socialize as much as other animals.But the larger Pacific striped octopus (LPSO) is different. For one, they live together in colonies. And mating is not only a safer proposition, it involves beak-to-beak “kissing.” Plus, females can lay eggs repeatedly, even tending to embryos at various stages of development.But because these behaviors are so uncharacteristic of most octopuses, the scientific community didn't officially recognize their existence until 2015, despite the decades-long effort of a Panamanian diver and artist named Arcadio Rodaniche. When he tried to share his findings about the LPSO at a symposium and publish them in a journal, he was flatly rejected. But his persistent research and documentation of the species would eventually be validated when researchers were able to obtain and observe the octopuses in captivity.SciFri producer Kathleen Davis sits down with freelance science writer Kenna Hughes-Castleberry to talk about an article she reported for Science Friday about the late Rodaniche and his yearslong effort to get official scientific recognition for the LPSO.Read the story at sciencefriday.com.Squid With ‘Giant' Eggs Could Be A New SpeciesTo finish up our celebration of Cephalopod Week we wanted to share a bit of squid news. A group of researchers recently identified a potentially new squid species in the family Gonatidae. Scientists took a closer look at some video footage captured back in 2015 and found a deep-water squid that was cradling some rather large eggs, which was not in line with other squid of the same family.John Dankosky talks with Dr. Bruce Robison, midwater ecologist and senior scientist at the Monterey Bay Aquarium Research Institute, about this new discovery.Transcripts for each segment will be available after the show airs on sciencefriday.com.  Subscribe to this podcast.

Some birds are famous for being extinct, like the Dodo and the passenger pigeon.But how do we prevent species from reaching that point? One of the starting points is to try and track down the birds that are “lost to science.” These are birds that have not been documented in over a decade, but just might still be out there, if we look for them.A new study analyzed data, images, and recordings from platforms that crowdsource observations from all over the world to identify birds “lost to science.” In total, the project, called The Search for Lost Birds identified 126 such species.SciFri producer Kathleen Davis is joined by Dr. John Mittermeier, director of the Search for Lost Birds at the American Bird Conservancy to talk more about the findings of this research and what it's like to track down a “lost” bird.Transcripts for each segment will be available after the show airs on sciencefriday.com.

Researchers say the Wet Bulb Globe Temperature is a better indicator of heat stress. Also, cancer is the leading cause of death in dogs. A new vaccine has increased survival rates in clinical trials, offering hope for dogs and humans.Yes, It's Hot. But How Hot?Much of the country has been enduring a heat wave this week, with millions sweating from Maine to the Midwest. But describing exactly how hot it is—and when temperatures become hazardous—can be challenging. Beyond the basic temperature, there's the heat index, invented in 1978, which incorporates humidity measurements and is supposed to give a better indication of how a person might feel outside. Some health researchers are calling for more attention to a different type of temperature measurement known as the wet bulb globe temperature. It tracks temperature, humidity, and sunlight, and improves upon the heat index standard.Umair Irfan, senior correspondent at Vox, joins SciFri's Kathleen Davis to talk about measuring temperatures and protecting yourself from extreme heat. Plus, they discuss other stories from the week in science, including advances in tornado prediction, a delay in a return flight from the International Space Station, and a newly-described horned dinosaur that once roamed the US.A Canine Cancer Vaccine Shows Promising ResultsDogs are by far the most popular pet in the United States: 62 million households have at least one. They are humans' best friends, after all. Sadly, cancer is the leading cause of death in domestic dogs. And when a pet gets sick, it can be devastating for the entire family.Lucky for dogs (and their people), there may soon be a breakthrough in treating canine cancer: a vaccine that can slow and even stop the spread of tumors. Clinical trial results are quite promising so far, increasing 12-month survival rates in dogs with some cancers from 35% to 60%. The research team also reports that in many dogs the vaccine shrinks tumors.Joining guest host Kathleen Davis to talk about this novel therapy is Dr. Mark Mamula, professor of medicine at the Yale School of Medicine in New Haven, Connecticut. Mamula discusses this important breakthrough, and possible future applications for human cancer therapies.Transcripts for each segment will be available after the show airs on sciencefriday.com.

The first Women's World Cup was in 1991, and the games were only 80 minutes, compared to the 90-minute games played by men. Part of the rationale was that women just weren't tough enough to play a full 90 minutes of soccer.This idea of women as the “weaker sex” is everywhere in early scientific studies of athletic performance. Sports science was mainly concerned with men's abilities. Even now, most participants in sports science research are men.Luckily things are changing, and more girls and women are playing sports than ever before. There's a little more research about women too, as well as those who fall outside the gender binary.SciFri producer Kathleen Davis talks with Christine Yu, a health and sports journalist and author of Up To Speed: The Groundbreaking Science of Women Athletes, about the gender data gap in sports science.Read an excerpt of Up to Speed: The Groundbreaking Science of Women Athletes at sciencefriday.com.Transcripts for each segment will be available after the show airs on sciencefriday.com.  Subscribe to this podcast.

Some food has a larger carbon footprint when grown in urban settings than on commercial farms, while for other foods the reverse is true. Also, what's the difference between wildflowers blooming in the desert each spring, and the rare phenomenon of a “superbloom”?The Carbon Cost Of Urban Gardens And Commercial FarmsIf you have a home garden, you may be expecting that the food you grow has less of an environmental impact than food grown on large commercial farms. But new research throws some cold water on that idea. A study led by scientists at the University of Michigan examined 73 small urban gardening sites across the U.S., the U.K., France, Poland, and Germany, and found that food grown in urban settings produced six times more carbon emissions per serving than commercially grown food. The bulk of these emissions (63%) came from the building materials used for items like raised garden beds.However, there are some foods that have a smaller carbon footprint when grown at home. They include crops like tomatoes and asparagus, which sometimes need to be flown long distances or require power-hungry greenhouses when grown commercially.Jason Hawes, PhD candidate in the School for Environment and Sustainability at University of Michigan and lead author of the study which was published in Nature Cities, breaks down the results of the research with Ira. They talk about how urban farmers have responded to the findings, the positive social benefits of community gardens, and what home gardeners can do to lessen their carbon footprint.Why There Won't Be A Superbloom This YearIn California, wildflowers are in bloom.Last year, there was a superbloom. Though there's no official criteria, a superbloom is when there is an above average number of wildflowers blooming, mostly in desert regions of California and Arizona. It's an explosion of color in regions that typically have sparse vegetation.About a month ago, a few news articles hinted that maybe, just maybe, we were in for another superbloom year. Turns out we're not.Who decides when there's a superbloom anyway? And why did this year turn out not to be a superbloom after all?To answer those questions and provide an update on the state of California's wildflowers, SciFri producer Kathleen Davis talks with Dr. Naomi Fraga, director of conservation programs at the California Botanic Garden, and research assistant professor at Claremont Graduate University.Transcripts for each segment will be available after the show airs on sciencefriday.com.

A long-awaited rule from the EPA limits the amounts of six PFAS chemicals allowed in public drinking water supplies. Also, some spiders, beetles, and centipedes spend winter under snow in a layer called the subnivium. Plus, a drumroll for the total solar eclipse.EPA Sets Limits On ‘Forever Chemicals' In Drinking WaterThis week, the EPA finalized the first-ever national limits for the level of PFAS chemicals that are acceptable in drinking water supplies. Those so-called “forever chemicals,” per- and polyfluoroalkyl substances, have long been used in products like fire retardants and oil-and water-repellent coatings, and are now ubiquitous in the global environment. Water treatment plants will now have to test and treat for several varieties of the chemicals, which have been linked to a variety of health problems in people.Sophie Bushwick, senior news editor at New Scientist, joins SciFri producer Kathleen Davis to talk about the rule and its potential impact on water agencies. They'll also talk about other stories from the week in science, including research into a new vaccine against urinary tract infections, theories that extend the multiverse into a many-more-worlds interpretation, the passing of particle physicist Peter Higgs, and a new front in the war on pest rats: rodent contraceptives.Where Snowpack Meets Soil: An Important Winter Home For BugsWhen winter rolls around and snow piles up, many insects head down to a small layer called the subnivium for the season.. This space, between snowpack and soil, shelters small insects, amphibians,and mammals from freezing temperatures.Arthropods as a whole are understudied, says Chris Ziadeh, graduate of the University of New Hampshire and lead author of a recent study about the distinct communities that live in the subnivium. Better understanding which creatures call the subnivium home in the winter, as well as their behavior, could help us conserve them as the climate warms.Guest host Kathleen Davis talks to Ziadeh about winter arthropod activity, species diversity, and why we should all care about protecting insects in our communities.Drumroll Please! A Performance For The Solar EclipsePeople found all manner of ways to celebrate the solar eclipse that happened earlier this week, but one Science Friday listener found a particularly musical way to take in the experience.Matt Kurtz, a sound artist and musician based in Akron, Ohio, realized his town would be in the path of totality for the April 8 eclipse. So with some funding from Akron Soul Train, a local artist residency, he put together a percussion section (complete with a gong) to perform a drumroll and build suspense up until the moment of totality. They performed in Chestnut Ridge Park to a crowd of onlookers.“When you hear a [drumroll], it forces you to be like, something's about to happen,” he said in an interview. “It's a way to pay attention.”As the gong rang out and the crowd cheered, Kurtz put down his sticks and experienced his first solar eclipse totality. “It was a release,” he said. “I had a couple minutes of peace where I got to look at the stars and feel where all this work went to.”Transcripts for each segment will be available the week after the show airs on sciencefriday.com.

Sharks are somewhat notorious for their sense of smell and ability to sniff out prey deep in the ocean. There's that persistent myth that sharks can smell a drop of human blood from a mile away. But that's not exactly true. While sharks can smell human blood, they are more interested in sniffing out what's for dinner: other fish, crustaceans, and molluscs. Ocean currents also play a role in how far a scent can travel. However, shark noses are just as powerful as any other fish in the sea. SciFri producer Kathleen Davis talks with Dr. Lauren Simonitis, a National Science Foundation postdoctoral fellow in biology at University of Washington and Florida Atlantic University, about her shark nose research, and what questions remain about shark snoots.Transcripts for each segment will be available the week after the show airs on sciencefriday.com.

How can some people recall random facts so easily? It may have to do with what else they remember about the moment they learned the information. Also, in Kenya, an invading ant species pushed out ants that protected acacia trees. That had cascading effects for elephants, zebras, lions, and buffalo.A ‘Jeopardy!' Winner Studied How Trivia Experts Recall FactsWhen contestants play “Jeopardy!,” it can be amazing to see how quickly they seem to recall even the most random, obscure facts. One multi-time “Jeopardy!” contestant, Dr. Monica Thieu, noticed something interesting about the way that she and her fellow contestants were recalling tidbits of information. They weren't just remembering the facts, but also the context of how they learned them: where they were, what they read, who they were with. Hypothesizing that for trivia superstars, information was strongly tied to the experience of learning it, she put that anecdotal evidence to the test. The results of her research were recently published in the journal Psychonomic Bulletin & Review.SciFri producer Kathleen Davis talks with Dr. Thieu, a psychology researcher at Emory University, and Dr. Mariam Aly, assistant professor of psychology at Columbia University, and a co-author of the new study. They discuss the psychology of trivia, how to get better at it, and why some people seem to be much more adept at recalling fun trivia facts than others.See if you can beat a "Jeopardy!" champ on our website!How One Invading Ant Species Sent Ripples Through A Food WebWhen people talk about the interconnectedness of nature, the usual example involves a little fish that eats a bug, a bigger fish that eats the little fish, and an even bigger fish at the top of the chain. But in reality, the interconnected relationships in an ecosystem can be a lot more complicated. That was certainly the case in a recent study, published in the journal Science, which describes how the arrival of an invasive ant species changed the number of zebras that get eaten by lions on the Kenyan savannah.The unwelcome ant is known as the big-headed ant. It's on a list of top 100 invasive species around the world. When it arrived on the African savannah, the ant newcomer muscled out a native ant species known as the acacia ant—which, though tiny, was able to help defend acacia trees from being grazed upon by elephants (picture getting a trunkful of angry ants while snacking).With the trees undefended, hungry elephants feasted, resulting in fewer trees on the savannah and more open space. That made the hunting environment less favorable to stealthy lions, and more favorable to fleet-footed zebras. But to the surprise of the researchers involved with the study, that didn't mean hungrier lions. Instead, the lions shifted their hunting from targeting zebras to targeting buffalo instead.Dr. Jacob Goheen and Douglas Kamaru of the University of Wyoming join guest host Sophie Bushwick to describe their research, and how a small ant can have a big effect on an ecosystem.Transcripts for each segment will be available after the show airs on sciencefriday.com.

Colorectal Cancer Rates Are Rising In Young PeopleGastrointestinal medicine practitioners have noticed something strange in recent years: More and more young people are being diagnosed with colorectal cancer.It used to be incredibly rare for anyone under the age of 50 to be diagnosed with colorectal cancer. Cases were generally limited to people with excess weight who live a sedentary lifestyle. But practitioners are increasingly seeing people in their 40s, 30s, and even 20s without prior risk factors being diagnosed with colorectal cancer.Jennifer Fijor is one nurse practitioner who has seen this rise in cases firsthand at Virginia Mason Franciscan Health in Seattle, Washington. Jennifer has been spreading awareness about this rise on her social media accounts.Jennifer speaks with guest host Kathleen Davis about the warning signs of colorectal cancer, such as sudden changes in bowel movements, and how patients can advocate for themselves to get screened early.What An AI Learns From A Baby's-Eye View Of The WorldThere's a lot to learn in the first couple of years of a child's life—not the least of which is how to talk. But little kids don't sit down and study a vocabulary book. They soak up language from daily experiences, which are often filled with parents and caregivers saying things like “look at the kitty cat.” Scientists wondered whether an artificial intelligence model could learn about language using a similar strategy—not by being fed a curated set of pictures and words, but by eavesdropping on the day-to-day activities of a small child.They found that associating images and sounds from 60 hours of video captured by a camera mounted on a baby's head could teach a computer model a set of several dozen basic nouns, such as “car,” “cat,” and “ball.” And the learning was generalizable, meaning that the computer was able to properly identify cars and cats that it had not seen before.Dr. Wai Keen Vong, a research scientist in the Center for Data Science at New York University and one of the authors of a study recently published in the journal Science, joins SciFri's Kathleen Davis to talk about the research and what it can teach us about learning.Transcripts for each segment will be available the week after the show airs on sciencefriday.com.

The idea of creatures from another planet is part of our culture, from the warnings of the alien in “The Day the Earth Stood Still,” to the plaintive desire to return home in “E. T. the Extra-Terrestrial,” to the hulking creature of “Nope.” Aliens appear in movies, books, comics, you name it. But are they more than science fiction? And if they were, how would scientists prove it?The government has investigated reports of alien sightings, including in Project Blue Book, which ran from 1947 to 1969. And last summer, congressional hearings into Navy pilots' sightings of Unidentified Anomalous Phenomena (UAPs) brought the search for intelligent life back into the public eye. But there's more to the search for alien life than people spotting lights in the sky. Projects such as Breakthrough Listen are surveying the stars for signals. Advanced telescopes such as JWST are enabling us to collect data on the atmospheres of exoplanets, a first step in detecting biosignatures on distant worlds. And astrobiology projects such as the Mars 2020 Perseverance rover mission are looking for signs of ancient life elsewhere in our own solar system.Dr. Adam Frank, a professor of astrophysics at the University of Rochester and author of The Little Book of Aliens, joins hosts Ira Flatow and Kathleen Davis to talk about the evidence for life elsewhere in the universe, and how scientists might go about trying to answer the question of whether we're alone.Transcripts for each segment will be available after the show airs on sciencefriday.com.

With this week's delays to Artemis II and III, astronauts likely won't walk on the moon until 2026 at the earliest. Also, weight-loss drugs, AI, clean-energy tech and more: digging into MIT Technology Review's annual list with executive editor Amy Nordrum.NASA Once Again Delays Artemis Crewed Missions To the MoonThis week, NASA announced that it was delaying two of its planned crewed missions to the moon. Artemis II, which was scheduled to launch in November 2024, was pushed to September 2025. And Artemis III, originally planned for late 2025, is now looking at a September 2026 launch date. The Artemis campaign has faced challenges with its lunar landers, spacesuits, life-support systems, and the Orion capsule's heat shield, according to NASA. When launched, Artemis II will swing around the moon and return to Earth, while Artemis III will land on the south pole of the moon, and will mark the first time humans have walked on the moon since 1972.Joining Ira to talk about this and other top science stories in the news this week is Casey Crownhart, climate reporter at MIT Technology Review. They talk about challenges facing the offshore wind industry, a Hawai‘i coal plant that was replaced by a battery farm, why AI weather forecasting is not ready for primetime, and a new discovery that giant apes went extinct earlier than we thought—and for a different reason.Top Technologies To Watch In 2024The technology world moves so fast, it can be hard to know what to pay attention to. Sometimes it's helpful for someone to tell you straight up who the big players are, and what technologies really could change the world.Luckily for us, MIT Technology Review compiles an annual list of the 10 breakthrough technologies they say matter most. This year, that list ranges from super-efficient solar panels to weight-loss drugs, and AI in just about everything.Joining guest host Kathleen Davis to discuss this year's list is Amy Nordrum, executive editor at MIT Technology Review based in Boston, Massachusetts.Transcripts for each segment will be available the week after the show airs on sciencefriday.com.

It can be hard to avoid the chime of classic Christmas songs at this time of year. Certain songs may even bring up potent memories, transporting a person to a specific moment in the past, like an afternoon baking cookies as a child, or warming up after playing in the snow.Music, when coupled with emotion, has the ability to create powerful memories. And listening to songs associated with specific memories can almost feel like going back in time.Better understanding how this mechanism works is the work of Assistant Professor Dr. David Clewett and PhD candidate Mason McClay, both in UCLA's cognitive psychology department. They talk with SciFri producer Kathleen Davis about how this method could be used to improve therapies for PTSD and other memory disorders.Transcripts for this segment will be available the week after the show airs on sciencefriday.com.

Research shows some rapidly evolving trout are altering Wyoming's aquatic ecosystems. Plus, paleontologists pieced together a level of apex predators with no modern equivalent. In Wyoming's Mountain Lakes, Stocked Trout Are Evolving QuicklyAnglers across the West love to fish in high, alpine lakes, and Wyoming's Wind River Range is nearly unbeatable for this experience. Around this time of year, frost covers the tips of trees at sunrise, and there's plenty of room along the lonesome blue waters above 10,000 feet.Those who do make the trek—which usually takes more than 15 miles of hiking—are greeted by hungry golden, brook or cutthroat trout looking to fatten up for the winter. They'll take almost any fly, from a yellow foam grasshopper, to a Parachute Adams to a tiny ant. And the fish are often big, colorful and photogenic.But as untamed, historic and relaxing as a day on the water feels, it's anything but natural. New research is shedding light on how the history of fish stocking has impacted alpine lake ecosystems in the Wind Rivers. In many cases, the genetics of trout have evolved rapidly, allowing them to survive in harsh mountain environments.Read the rest at sciencefriday.com. Hyper-Apex Predators: Colombian Fossils Reveal Big Reptilians Atop Ancient Marine Food ChainThe Paja Formation, located in central Colombia, is a treasure trove of fossils. The site is integral to scientists' understanding of ancient creatures who roamed the seas during the Early Cretaceous period, about 130 million years ago.Now, paleontologists have pieced together the food chain of this marine ecosystem. Surprisingly, they found it supported an additional level of apex predators—think massive marine reptiles—for which there is no modern equivalent.SciFri producer Kathleen Davis talks with Dirley Cortés, paleontologist at the Centro de Investigaciones Paleontológicas in Colombia and PhD candidate at McGill University's Redpath Museum, and Dr. Hans Larsson, paleontologist and professor at McGill University's Redpath Museum.

Seven “clean energy hubs” will receive a total of $7B to develop forms of hydrogen production with minimal carbon emissions. And, ahead of the US Grand Prix, an aerodynamicist breaks down the recent engineering changes to F1 cars.Department Of Energy Announces ‘Clean Hydrogen Hub' AwardeesThe Department of Energy announced seven “clean hydrogen hubs,” which will receive a cumulative $7 billion. Each group will use a host of different approaches to produce hydrogen fuel with little or no emissions.SciFri producer Kathleen Davis talks with Casey Crownhart, climate reporter for MIT Technology Review, to break down the details of this announcement and other top science news of the week, including seals helping map a canyon in Antarctica, the number of living cells in the world, and a very spicy pepper.Formula One Cars Are Stripping Off Paint To Save WeightFormula One is known as the pinnacle of motorsport, with cars that can reach speeds of 230 miles per hour. Thanks to the Netflix series Drive To Survive, the sport is more popular than ever.As engineers prepare for the U.S. Grand Prix in Austin, Texas, this Sunday, teams strive to make their cars as fast as possible. To do so, they try to reduce the ultra-fast cars' weight by altering the construction of the frame of the car, or finding lighter engine parts. But recently, many teams have been stripping the paint off the cars instead.Even though paint on an F1 car only adds up to about three pounds, races can be won by milliseconds, so every ounce counts. In the last couple years, many teams made the decision to pare down the amount of paint used on the cars, exposing the natural black color of the carbon fiber below it. It's why the cars on the grid look darker overall, compared to previous years.Kyle Forster, a former aerodynamicist for the Mercedes-AMG F1 team and a lead aerodynamicist for JKF Consultants, breaks down the engineering changes made to F1 cars in recent years, the newest in paint science, and what aerodynamic changes he hopes to make in the years to come.To stay updated on all things science, sign up for Science Friday's newsletters.

Youth Climate Activists Score A Win In MontanaThis week, a state court in Montana ruled in favor of a group of 16 youth climate activists, who argued that a state environmental law was in violation of a provision in the state constitution. The Montana constitution states: “The state and each person shall maintain and improve a clean and healthful environment in Montana for present and future generations.”  The ruling will allow (but not require) regulators to consider climate impacts when evaluating proposed energy projects for approval.Umair Irfan, staff writer at Vox, joins Ira to talk about the decision and what it might mean for other climate-related litigation around the country. They'll also discuss other science news of the week, including some strange particle physics from Fermilab,  the end of the road for the common incandescent light bulb, and how researchers decoded a snippet of song — using electrodes on a brain. COVID-19's Summer Wave Raises New QuestionsStep outside into a public place, and you may experience some deja-vu: Masking is back up, the coughs and sniffles are echoing, and coworkers are calling in sick. It's not just your imagination—hospitalizations from COVID-19 are up 14.3 percent for the week of August 5. This new wave has a name: EG. 5, named for the recent Omicron variant that is now the most prevalent.With new boosters on the horizon, Ira catches up with Dr. Angela Rasmussen, virologist at VIDO, the Vaccine and Infectious Disease Organization, at the University of Saskatchewan. They answer questions about the new monovalent booster, testing guidance, and why COVID-19 is still a public health problem.New Research Suggests Neurological Culprit For COVID Brain FogAmong the most debilitating symptoms of Long Covid is brain fog, a condition which includes symptoms like confusion or inability to concentrate. A recently published study using mice cells in petri dishes suggests that brain fog might be the result of neurons fusing together. The results have yet to be tested in live animals or humans. SciFri producer Kathleen Davis talks with study author, Dr. Ramón Martínez-Mármol, research fellow at the Queensland Brain Institute, at the University of Queensland, based in Brisbane, Australia, about what his research might help us better understand about brain fog. Reno Is Preparing To Turn Its Wastewater Into Drinking WaterInside a water treatment plant in north Reno, Nev., on a recent Wednesday, recycled wastewater was running beneath a floor grate inside a small testing room. Inside the space is a system of serpentine-like PVC pipes with 19 different ports, used to test water samples at different intervals.“It's about halfway through the treatment process at the wastewater facility,” said Lydia Teel, an engineer with the Truckee Meadows Water Authority, or TMWA, which serves about 440,000 people in the greater Reno area. “So, it's clean, but there's still some color, there's bacteria in it, some solids.”Teel spearheads a demonstration project called OneWater Nevada, an effort to show that the region can recycle the water that flushes down people's toilets and shower drains and – eventually – turn it back into clean, pure drinking water flowing from faucets, effectively creating a new water resource. The project is a collaboration between TMWA, the cities of Reno and Sparks, the University of Nevada, Reno, Washoe County, and the Western Regional Water Commission.The Reno area doesn't have a history of threatened water supplies, and historic snowfall this past winter eased drought conditions in Nevada and across parts of the Mountain West. But that could shift quickly with climate change.To stay updated on all-things-science, sign up for Science Friday's newsletters.Transcripts for each segment will be available the week after the show airs on sciencefriday.com.

Challenging The Gender Gap In Sports ScienceThis weekend, Spain and England face off in the Women's World Cup Finals in Sydney, Australia.The first Women's World Cup was in 1991, and the games were only 80 minutes, compared to the 90-minute games played by men. Part of the rationale was that women just weren't tough enough to play a full 90 minutes of soccer.This idea of women as the “weaker sex” is everywhere in early scientific studies of athletic performance. Sports science was mainly concerned with men's abilities. Even now, most participants in sports science research are men.Luckily things are changing, and more girls and women are playing sports than ever before. There's a little more research about women too, as well as those who fall outside the gender binary.SciFri producer Kathleen Davis talks with Christine Yu, a health and sports journalist and author of Up To Speed: The Groundbreaking Science of Women Athletes, about the gap in sport science about women. Using Stem Cells For Cornea Repair Is Worth A LookEach year in the US, over 40,000 people receive transplants of the cornea—the clear front part of the eye that light goes through first. Still more patients with damaged corneas might receive artificial corneas to help restore clear vision. But if an eye has been damaged by a chemical burn or another severe eye injury, neither of those treatments may be possible.Now an early, Phase 1 clinical trial is reporting positive results using a stem cell technique called CALEC. It grows cells from a patient's healthy eye, and then grafts them back into the damaged eye, either to support corneal tissue regrowth or as a foundation for a traditional transplant. Dr. Ula Jurkunas, associate director of the Cornea Service at Mass Eye and Ear, and   Dr. Jerome Ritz, the executive director of the Connell and O'Reilly Families Cell Manipulation Core Facility at Dana-Farber Cancer Institute, join Ira to talk about how the process works, and the challenges of manufacturing stem cell tissues in the lab for use in the human body.From Skyscrapers to Sand Thieves—Digging Into The World Of SandWhen you think of sand, thoughts of the ocean and sand castles probably come to mind. But sand can be found in much more than beachfronts. Sand is a key ingredient in concrete for skyscrapers, silicon for computer chips, and the glass for your smartphone.Vince Beiser, journalist and author of the book The World in a Grain: The Story of Sand and How it Transformed Civilization, traveled to sand mines in India and beach nourishment projects around the world to follow the story of how sand has become a vital resource. He talks about the many uses of sand in our everyday lives and some of the consequences that come from our dependence on this natural resource.To stay updated on all-things-science, sign up for Science Friday's newsletters.Transcripts for each segment will be available the week after the show airs on sciencefriday.com.

Listen on Apple Podcasts, Spotify, or wherever you get your podcasts.   No, The Gulf Stream Is Not Collapsing A sobering climate study came out this week in the journal Nature Communications. It suggests that a system of ocean currents—called the Atlantic meridional overturning circulation (AMOC)—could collapse sometime between 2025 and 2095, which could have dire climate consequences for the North Atlantic. SciFri director of news and audio John Dankosky talks with Swapna Krishna, a journalist based in Philadelphia, about what this means and what could be at stake. They also chat through other big science news of the week, including the detection of water vapor around a very distant star, a new image depicting the first detection of gas giants being formed around stars, a new theory for the origin of the world's “gravity hole,” why the fuzzy asp caterpillar packs such a scary sting, and what scientists can learn from ticklish rats.   The State Of Reproductive Health, One Year After Dobbs In the year since the Supreme Court decided Dobbs v. Jackson Women's Health Organization, overturning the federal right to an abortion, states jumped into action. Thirteen states banned abortion with limited exemptions, and three others have banned abortion after the first trimester. A handful of other states have extremely restrictive abortion access, or otherwise remain in legal limbo, awaiting court decisions or new laws to be signed. Leading up to Dobbs decision, SciFri delved into the science behind reproductive health and the potential ripple effects on access to care. Now, a little over a year later, we're following up what's going on. SciFri guest host and experiences manager Diana Plasker talks with Usha Ranji, associate director for Women's Health Policy at the Kaiser Family Foundation, based in San Francisco, California, about her survey of 569 OB-GYNs across the country. They discuss the growing disparities in states between where abortion is banned and where it remains legal. Later, John Dankosky talks with Dr. Rebecca Cohen, chief medical officer at the Comprehensive Women's Health Center, based in Denver, Colorado, about providing abortion and pregnancy care in a state where abortion is legal, and seeing patients who are traveling from states with bans in place.   The Kākāpō Parrot Returns To New Zealand Before humans arrived in New Zealand, parrots called kākāpō freely roamed across the islands. They are the world's only living flightless parrots, and they're a bit smaller than the average chicken. But the kākāpō's population started crashing centuries ago, due to human interference and the arrival of predators like cats, rats, and stoats. At one point, the species was teetering on the brink of extinction. For decades, scientists have been capturing and relocating kākāpō to safe islands, hoping their population would grow. It did, and the kākāpō's recovery team just reached a huge milestone: bringing four birds back to the mainland, a place they haven't existed since the 1980s. Guest host and SciFri events manager Diana Plasker talks with Deidre Vercoe, operations manager for the New Zealand Department of Conservation's kākāpō and takahē teams, about the history of kākāpō conservation, what this win means, and what's next for these beloved birds.   Far Beyond Their Native Habitat, Parrots Rule The Roost In many urban areas across the U.S. and abroad, feral, non-native parrots have become established. This is true in Brooklyn's Green-Wood Cemetery, where a colony of lime green monk parakeets have inhabited a massive nest on top of the gothic entrance gate. How exactly these parrots wound up here is a bit of a mystery. “The lore that's passed around is that at some point a box of parrots, perhaps at the airport, got overturned,” said science writer Ryan Mandelbaum. “What's more likely is a combination of people releasing their [pet] parrots and parrots escaping in some critical mass.” Mandelbaum wrote the cover story for July's issue of Scientific American all about the resilience of parrots. SciFri producer Kathleen Davis interviewed them at Green-Wood Cemetery, where they discussed why these parrots are not just surviving, but thriving.   To stay updated on all-things-science, sign up for Science Friday's newsletters.

How Fungi Are Breaking The Binary: A Queer Approach To Ecology As Pride month comes to a close, many people are reflecting on the past, present, and future of the LGBTQIA+ community. An interdisciplinary group of scientists, researchers, and artists are using queerness as a lens to better understand the natural world, too. It's a burgeoning field called queer ecology, which aims to break down binaries and question our assumptions of the natural world based on heterosexuality. For example, there are plenty of examples of same-sex animal pairings in the wild, like penguins, chimps, and axolotls. There are also plants that change sexes, or have a combination of male and female parts, like the mulberry tree. But perhaps the most queer kingdom of all is fungi. Mushrooms are not easily forced into any type of binary. For example, the Schizophyllum commune, or the split gill mushroom, has 23,000 sexes, making it somewhat of a queer icon in the field of mycology. SciFri producer Kathleen Davis talks with Patty Kaishian, incoming curator of mycology at the New York State Museum, about how fungi might help us expand our understandings of sexuality, identity, and hierarchy. They also discuss how queer ecology can help people of all sexualities reconnect with the natural world.   Scientists Think Cloning Could Help Save Endangered Species Earlier this year, a baby Przewalski's horse was born at the San Diego Zoo. But this foal isn't any ordinary foal, he's a clone. He's the product of scientists aiming to save his dwindling species using genetics. This endangered horse species once roamed Europe and Asia, but by the 1960, threats like poaching, capture, and military presence drove the horses to extinction in the wild. Conservationists raced to save this wild horse through captive breeding programs, but with a population so small, there just wasn't enough genetic diversity to grow a healthy herd. But with careful genetic management, the Przewalski's horse's population is now nearly 2,000 horses strong, and this new foal will one day help boost his species' genetic diversity even more. Producer Kathleen Davis talks with Dr. Oliver Ryder, conservation geneticist at the San Diego Zoo Wildlife Alliance, about cloning Przewalski's horse, and how doing so will infuse genetic diversity into the small population. Then Davis talks with Dr. Sam Wisely, professor of wildlife ecology and conservation at the University of Florida, about how cloning can help other endangered species, like the black-footed ferret, and the ethics involved in cloning.   Twenty Years On, The Little CubeSat Is Bigger Than Ever The story of the CubeSat started with a big problem for one Cal Poly professor. “It was actually a critical problem for us, but it was a problem that nobody else cared about,” said Jordi Puig-Suari, an Emeritus Professor from Cal Poly San Luis Obispo. He co-invented the CubeSat with Bob Twiggs from Stanford. Puig-Suari is now retired and has spent the last four years sailing around the world with his wife. I talked to him over Zoom from somewhere along that journey. He takes me back two decades to his time as a professor at Cal Poly where he was hired to develop their aerospace engineering department.

Titanic. That search turned out, sadly, to be in vain. The Titan submersible is believed to have imploded in the North Atlantic, killing all aboard. The intersection of design, engineering, and human risk-taking is a recurring theme throughout modern history. One of the finest chroniclers of those tales was Henry Petroski, who died earlier this month at the age of 81. He was a professor of engineering and history at Duke University, and author of many books. Petroski was known for his critical eye and insightful view of various missteps and faults in pursuit of progress—from improving bridge designs for safety to the tragic loss of the space shuttles Challenger and Columbia. Some called Petroski the “poet laureate of technology” for his prolific writings on everything from the design of bridges to the fabrication of pencils. In this recording from 2012, Ira Flatow spoke with the late professor Petroski about engineering failures, and humanity's follies.   To stay updated on all-things-science, sign up for Science Friday's newsletters.
