What happens when AI moves beyond convincing chatbots and custom image generators to something that matches—or outperforms—humans?Each week, tech companies trumpet yet another advance in artificial intelligence, from better chat services to image and video generators that spend less time in the uncanny valley. But the holy grail for AI companies is known as AGI, or artificial general intelligence—a technology that can meet or outperform human capabilities on any number of tasks, not just chat or images.The roadmap and schedule for getting to AGI depends on who you talk to and their precise definition of AGI. Some say it's just around the corner, while other experts point a few years down the road. In fact, it's not entirely clear whether current approaches to AI tech will be the ones that yield a true artificial general intelligence.Hosts Ira Flatow and Flora Lichtman talk with Will Douglas Heaven, who reports on AI for MIT Technology Review; and Dr. Rumman Chowdhury, who specializes in ethical, explainable and transparent AI, about the path to AGI and its potential impacts on society.Transcripts for each segment will be available after the show airs on sciencefriday.com.

Pancreatic cancer is notoriously difficult to treat, and about 90% of diagnosed patients die from the disease. A team at Memorial Sloan Kettering has been working to improve those outcomes by developing a new mRNA vaccine for pancreatic cancer.A few years ago, the team embarked on a small trial to test the vaccine's safety. Sixteen patients with pancreatic cancer received it, and even though it was a small study, the results were promising: Half the participants had an immune response, and in those patients the cancer hadn't relapsed after 18 months.This week, the team released a new study in Nature following those same patients, and found six out of eight who responded to the vaccine in the first study did not have their cancer return more than three years later.Joining host Flora Lichtman to talk about these results, and what they could mean for the future of cancer treatment, is study author and surgeon Dr. Vinod Balachandran, director of The Olayan Center for Cancer Vaccines at Memorial Sloan Kettering, based in New York City.Transcripts for each segment will be available after the show airs on sciencefriday.com.  Subscribe to this podcast.

It seems that every few months, there's an exciting breakthrough in quantum computing, a kind of computing that takes advantage of quantum physics to perform calculations exponentially faster than our most advanced supercomputers. Last December, Google announced that its quantum computer solved a math problem in five minutes—a problem that would've taken a normal supercomputer longer than the age of the universe to solve. And earlier this month, Microsoft, coming off a quantum advance in the fall, told businesses to get “quantum-ready” for 2025, saying that “we are right on the cusp of seeing quantum computers solve meaningful problems.”So, are we on the cusp? Flora Lichtman is joined by Dr. Shohini Ghose, a quantum physicist and professor at Wilfrid Laurier University in Waterloo, Canada and CTO of the Quantum Algorithms Institute, for a quantum computing check-in and a look at when this futuristic technology could start to have an impact on our lives.

About four and a half years ago, a spacecraft called OSIRIS-REx touched down on the surface of an asteroid called Bennu. It drilled down and scooped up samples of rock and dust and, after several years of travel, delivered those samples back to Earth.Since then, researchers around the world have been analyzing tiny bits of that asteroid dust, trying to tease out as much information as they can about what Bennu is like and where it might have come from. Two scientific papers published this week give some of the results of those experiments. Researchers found minerals that could have arisen from the drying of an icy brine, and a soup of organic molecules, including ammonia and 14 of the 20 amino acids necessary for life on Earth.Dr. Danny Glavin and Dr. Dante Lauretta join Flora Lichtman to talk about the samples, what their analysis is revealing, and what those findings could mean for the hunt for life elsewhere in the solar system.Transcripts for each segment will be available after the show airs on sciencefriday.com.

After nearly four weeks of burning, the fires in Los Angeles are almost fully contained, and cleanup is underway. But as the dust literally settles, people in LA are left with major questions, like: What is actually in the ash? What's in the air? And how do I stay safe?Flora Lichtman talks with two experts in public health and toxic substance exposure about the chemicals left behind after an urban fire as well as what science needs to be done to fully understand the issue. She speaks with Dr. Rima Habre, associate professor of environmental health and spatial sciences at the University of Southern California in Los Angeles; and Dr. Mark Wilson, director of exposure science at Chemical Insights Research Institute (CIRI) in Marietta, Georgia.Transcript for this segment will be available after the show airs on sciencefriday.com.

The outbreak of H5N9 avian influenza occurred at a California duck farm in November 2024. Also, new research pinpoints 298 parts of the genome associated with higher risk of bipolar disorder. This could lead to better treatments.Another Strain Of Bird Flu Discovered In CaliforniaThis week, the World Organization for Animal Health reported that it had been notified by the USDA that a November outbreak of highly pathogenic avian influenza on a California duck farm was caused by a strain not before seen in the United States: H5N9. The dominant bird flu strain circulating currently, H5N1, has led to massive culling of bird flocks, has infected dairy cattle, and has killed almost 500 people around the world since 2003. The US reported its first human death from bird flu earlier this month.Experts stressed that the new strain did not itself appear to be an immediate human threat. But the rise of a new strain is troubling and points to the risk of a viral phenomenon known as “reassortment,” in which different viruses mingled in a host can sometimes exchange bits of viral code, forming new strains.SciFri's Charles Bergquist joins Flora Lichtman to talk about H5N9 and other stories from the week in science, including a spacewalk that was meant to include a search for microbes on the outside of the International Space Station, a possible positive side effect of scratching an itch, and the discovery of 66 million-year-old fossilized vomit.Understanding Bipolar Disorder Through The GenomeBipolar disorder is one of the most common mental illnesses—it affects an estimated 40 million people worldwide, about 2.8% of the population. Bipolar disorder can cause extreme mood swings, and be debilitating without treatment.In an effort to untangle the mysteries of where bipolar disorder originates, researchers studied the genomes of more than 40,000 people with the condition. When comparing these genomes to those of people without bipolar disorder, the researchers were able to pinpoint 298 different parts of the genome associated with the mental illness. With this better understanding of the genome, better, more targeted treatments for bipolar disorder may be possible.Joining Flora to talk about this research is Dr. Niamh Mullins, assistant professor of psychiatric genomics at the Icahn School of Medicine at Mount Sinai in New York.Transcripts for each segment will be available after the show airs on sciencefriday.com.

Health psychologist Dr. Kari Leibowitz traveled to some of the coldest, darkest places on earth to learn how people there don't just survive, but thrive in winter. She says that one of the key ingredients is adopting a positive wintertime mindset by focusing on and celebrating the good parts of winter.Flora Lichtman talks with Dr. Kari Leibowitz, author of How to Winter: Harness Your Mindset to Thrive on Cold, Dark, or Difficult Days, about saunas, cold plunges, candles, and other small ways to make winter a season to look forward to rather than dread. Plus, she responds to some of our audience's own tips to make the season enjoyable.What Would You Call The Fun Parts Of Winter?Do you think “winter doldrums” needs a positive rebrand?

Birds are the master vocalists of the animal kingdom. They can make a remarkable variety of sounds.But why is a barred owl more of a baritone, while a cedar waxwing is a soprano?And what influences a bird's vocal range, and the kinds of sounds it can make? Beak size? Body size? Geography?To answer some of these questions, researchers analyzed over 140,000 bird vocalizations from all over the world to try to peck out some kernels of knowledge about bird calls and songs. Their research was recently published in Proceedings of the Royal Society B.Flora Lichtman talks with Dr. Zuzana Burivalova, assistant professor of forest & wildlife ecology at the University of Wisconsin-Madison about her latest research.Transcripts for each segment will be available after the show airs on sciencefriday.com.

A recent study in the journal Nature unveiled new proteins that can neutralize the deadliest of snake venoms. They're “new” in that they aren't found in nature—they were created in a lab, dreamed up by AI.Using AI to discover, or design, the building blocks of drugs is a fast-growing area of research. Another team of scientists out of Philadelphia is using AI to discover new antibiotics by resurrecting long-lost molecules from extinct species like neanderthals and woolly mammoths.We know what you're thinking: It sounds too sci-fi to be true.Flora Lichtman talks with two pioneers in the field about how AI is supercharging drug discovery: Dr. César de la Fuente, bioengineer and presidential associate professor at the University of Pennsylvania in Philadelphia, and Nobel laureate Dr. David Baker, director of the Institute for Protein Design and professor at the University of Washington in Seattle.Transcripts for each segment will be available after the show airs on sciencefriday.com.For our Los Angeles listeners: We're working on a story about the toxins left behind by the fires and we want to hear from you.

Researchers at the National Institutes of Health say the move has sent fear and confusion throughout the agency. Plus, what's the technology behind meme coins?Trump Administration Cancels Meetings, Freezes Hiring At NIHThis was President Trump's first week back in the Oval Office. Along with issuing a flurry of executive orders, his administration has imposed a range of restrictions on the National Institutes of Health, affecting meetings, travel, hiring, funding, and communications. Scientists expressed alarm about what this could mean for ongoing research, with no clear timeline for if or when the freeze would be lifted.Flora Lichtman is joined by Casey Crownhart, climate editor at the MIT Technology Review, to catch up on this and other big science stories of the week, including what's coming next this year for nuclear power, why a record amount of snow fell in the Southeast this week, and new research on the surprisingly complex biology of a manta ray tail.What Exactly Is A Meme Coin And How Does It Work?A few days before President Trump's inauguration, he hosted a “crypto ball” in Washington, D.C. That night, he unveiled his very own meme coin—a kind of digital asset that has gained a reputation for facilitating scams. Soon after, first lady Melania Trump also launched her own meme coin. After its launch, Trump's coin's market capitalization reached billions of dollars.This isn't the first time meme coins have gotten a lot of attention—you might remember Elon Musk joked about another one called Dogecoin on SNL in 2021—but it is the first time that this technology has been used by a sitting president. So what exactly is a meme coin anyway? How does the blockchain play into all this? And how might a president use it differently than an internet celebrity?To find out more, Flora Lichtman talks with Liz Lopatto, a senior writer at The Verge who covers cryptocurrency and business, about how this market started, how Trump could use meme coins, and where the crypto market could go next.Transcripts for each segment will be available after the show airs on sciencefriday.com.  Subscribe to this podcast.

Scientists investigated how the shape of the human body makes hula hooping possible—and what hips and a waist have to do with it. And, the decision for how to proceed with NASA's Mars Sample Return Mission will fall to the incoming administration.What Makes A Hula Hoop Stay Up?Hula hooping might appear to be a simple physical activity. But there's some complex math and physics at play as the hoop goes around your body, and scientists haven't had a clear understanding of those hidden forces—until now. A team of mathematicians at New York University recently published research into the science of hula hooping in the Proceedings of the National Academy of Sciences.Flora Lichtman is joined by Olivia Pomerenk, a PhD candidate in mathematics at New York University, and a coauthor of that paper. She talks with Flora about why the motion of hula hooping prevents the hoop from falling down and which body types make for the best hooper.NASA Considers Cheaper, Faster Ways To Retrieve Mars SamplesNASA's Mars Sample Return mission is an ambitious project that aims to use the Perseverance rover to collect Martian rocks, sand, and even gulps of Martian air. Then, through a complicated handoff between different spacecraft, it would ferry those samples to Earth.A 2023 assessment found that the original plan to retrieve the samples would be much more expensive, and take much longer, than initially expected.This week, NASA announced two options for how to cut costs and bring the samples to Earth by the late 2030s. But the agency did not solidify a plan, leaving it to the next administration to sort out around 18 months from now. Is the project on the rocks?To get up to speed on the mission, Flora Lichtman talks with Dr. Jim Bell, professor of earth and space exploration at Arizona State University, and distinguished visiting scientist at NASA's Jet Propulsion Laboratory.Transcripts for each segment will be available after the show airs on sciencefriday.com.   Subscribe to this podcast.

On January 6, the U.S. reported its first human death from the bird flu. According to the CDC, more than 60 people were diagnosed with bird flu in the US last year, up from just one case in 2022.If you look at global cases over the last two decades, of the nearly 900 reported cases in people, roughly half the patients died.H5N1 avian influenza has been circulating in birds—and even some mammals—for years. But in the spring of 2024, the virus turned up in dairy cattle. Since then, over 900 herds have been affected, according to the CDC.This might bring back memories from early in the COVID-19 pandemic—but is that the right way to think about this? Should we be concerned? And what steps should we be taking?To unpack this, host Flora Lichtman talks with Dr. Seema Lakdawala, co-director for the Center for Transmission of Airborne Pathogens and associate professor studying influenza viruses at Emory University in Atlanta, Georgia; and Dr. Richard Webby, director of the World Health Organization Collaborating Centre for Studies on the Ecology of Influenza in Animals and Birds and virologist at St. Jude's Children's Research Hospital in Memphis, Tennessee.Transcripts for each segment will be available after the show airs on sciencefriday.com.

After her SciFri internship 20 years ago, Flora went on to become a beloved science journalist, video producer, and podcaster. Now she's back! Also, several different fires are causing extreme damage in the Los Angeles area. Strong Santa Ana winds are one factor behind their rapid spread.Science Friday Now Has Two Hosts: Meet Flora Lichtman!Big news! Science Friday now has two hosts—Ira Flatow, the program's founder, and veteran science journalist Flora Lichtman. Going forward, you'll hear both of them regularly on the air and on our podcast. Flora joins Ira to introduce herself and talk about her background, from her start as an intern at Science Friday 20 years ago to her role as a video producer, then a writer for Bill Nye, and as creator of the podcast “Every Little Thing.”Los Angeles Wildfires Burn For Days, Stoked By Santa Ana WindsThis week, the Los Angeles area has been battered by at least five separate wildfires. Tens of thousands of acres have burned, and thousands of people have been forced to flee their homes. Fire experts had warned on January 2 that conditions were ideal for wildfires in parts of Southern California. One factor that has helped these fires spread rapidly? Unusually strong Santa Ana winds.On the other side of the country, Winter Storm Blair has caused freezing temperatures and up to a foot of snow across the Midwest and up into the East Coast, putting more than 60 million people under weather alerts.Joining Ira Flatow to discuss these and other top stories of the week is Umair Irfan, science correspondent at Vox, based in Washington, D.C.Transcripts for each segment will be available after the show airs on sciencefriday.com.

If you ask children what they want to be when they grow up, chances are good that among the answers, you'll hear “astronaut.” But becoming an astronaut can be more difficult than becoming a veterinarian, firefighter, marine biologist, or some of the other common childhood job aspirations. The odds aren't good: In 2021, NASA selected 10 astronaut candidates from a pool of over 12,000 applicants. And last year, over 22,000 applications to the European Space Agency resulted in 17 job offers.Dr. Mike Massimino's application to become a NASA astronaut was rejected several times. However, he persisted in his efforts, and eventually flew twice on the space shuttle, logging over 570 hours in space and over 30 hours spacewalking. On his second trip to orbit, on Atlantis mission STS-125, he participated in the last servicing mission for the Hubble Space Telescope.Massimino joins Ira and guest host Flora Lichtman to talk about his time at NASA. They also discuss lessons he learned at the space agency that he believes can help others achieve their goals, which he has collected in his new book, Moonshot: A Nasa Astronaut's Guide To Achieving The Impossible.To stay updated on all things science, sign up for Science Friday's newsletters.

What Causes Red Wine Headaches? It May Be QuercetinIt's a common experience: After a glass or two of red wine, relaxation can turn into a pounding headache. This isn't the same thing as a hangover, as the dreaded red wine headache kicks in between 30 minutes and three hours after imbibing.For years, there have been different theories about what causes this phenomenon. But neither sulfites or tannins have been proven to be the culprit. A new theory published in the journal Scientific Reports posits that quercetin, an antioxidant in grape skins, could create a toxic byproduct that leads to headaches.Dr. Morris Levin is one of the authors on this paper. He's the director of the Headache Center at the University of California San Francisco Medical Center, and has spent his career treating patients for migraines and other headache experiences. But Levin says there's not nearly enough funding for headache research as a whole, which leaves a lot of unanswered questions about the origins and meanings of this common ailment.Levin joins guest host Flora Lichtman to discuss red wine headaches, as well as the remaining mysteries of headaches.Worsening Wildfires Are Undoing Air Quality Progress In The USThe Western US has seen both more frequent and more intense wildfires over the past couple decades, leading to lower air quality and increased deaths in the region between 2000 and 2020, according to a new study published in The Lancet Planetary Health journal. While the EPA has made progress in improving air quality in the country, those gains are being undone by smoke from wildfires.The study looked at particulate matter called PM2.5 and a toxic component of it, black carbon. The researchers found that after years of trending downward nationally, the concentration of PM2.5–and the proportion of black carbon within it–began to increase in the West in 2010. This shift was linked to an increase of 670 premature deaths per year in the region.Joining Ira to talk about this and other science news of the week is Rachel Feltman, host of the podcast The Weirdest Thing I Learned This Week. They also discuss a surprise found in the oldest known mosquito fossil, why a national plastic bag recycling program was shut down, and why dwarf planet Eris' surface is a little squishy.  Transcripts for each segment will be available the week after the show airs on sciencefriday.com.

Reporter Ashley Ahearn bought a wild horse from the federal government for $125. Also, with opera and visual art, an exhibit looks at modern genetic engineering of pigs.The Captivating Story Of The West's Wild HorsesWild mustangs are an icon of the American West, conjuring a romantic vision of horses galloping free on an open prairie. But in reality, the Bureau of Land Management (BLM) says the sensitive Western ecosystem can't handle the existing population of horses.There are about 80,000 wild horses in the American West, a number that grows about 10-20% each year. The BLM says the fragile, arid rangelands the horses occupy can only support a third of that number before they overgraze habitats critical for other species. This has led to controversial roundups to get wild horses off the open range.Science and environment reporter Ashley Ahearn dove deep into the history, symbolism, and ecological impact of the West's mustangs for the new podcast Mustang. She even adopted a wild horse, named Boo, from the federal government for $125. Ashley speaks with guest host Flora Lichtman about her boots-on-the-ground reporting, and what she learned from how tribal nations manage mustangs.An Artist Explores The History Of Humans Genetically Modifying PigsOver 100,000 people are waiting for organ donations in the United States. Many will likely never receive one, since there are so few available. So scientists are turning to pigs for potential alternatives. Their organs are remarkably similar to ours, and scientists are now using CRISPR to modify pigs' DNA to improve transplantation outcomes. But although the field has shown major advances in the last decade, the technique isn't ready yet. Recently, a patient who received a modified pig heart died six weeks after the surgery.Artist Heather Dewey-Hagborg was intrigued by these recent advances, and looked into humanity's history of modifying the pig over thousands of years for her new gallery exhibit, Hybrid: an Interspecies Opera. For the work, she interviewed scientists and archaeologists and even filmed in a lab that's experimenting with genetically modifying pigs to create more human-compatible organs.In the resulting documentary, which plays in the exhibit, the words from the scientists she interviewed are transposed into an opera composed by musician Bethany Barrett. Visitors can also find 3D-printed clay pig statues and a timeline of how humans have transformed pigs over ten millennia, thanks to selective breeding.Dewey-Hagborg sat down with SciFri producer D. Peterschmidt to talk about how the exhibit came together, and how CRISPR could further transform pigs and our relationship to them. To stay updated on all things science, sign up for Science Friday's newsletters.

Moon Rocks Collected In 1972 Reveal New SecretsIt's hard to imagine, but the moon we all know and love hasn't always been in the sky. Like all of us, the moon has an age. Until recently, our lunar neighbor has been estimated to be about 4 billion years old.But new research on lunar crystals from the Apollo 17 mission has helped researchers pinpoint a more specific age for the moon—and it's about 40 million years older than previously thought.That difference may sound like a drop in the bucket given the time scales, but lead study author Dr. Jennika Greer says this is a big deal, because it tells us more about what the solar system was like in its earlier years. Greer, a postdoctoral researcher at the University of Glasgow in Scotland, joins guest host Flora Lichtman to talk about her methods and why the early universe was so fascinating.The Science Behind Your Unraveling SweatersIt's sweater season once again, but you may have noticed that some of your newer sweaters aren't standing the test of time. Perhaps they are pilling, unraveling, or losing their shape. But if you look at sweaters from the ‘80s or ‘90s, they may still look brand new. Last month, an article by Amanda Mull in the Atlantic about declining sweater quality made the rounds online, and we wanted to know more.What, scientifically, went wrong in sweaters? And why are sweaters so bad now?Guest host Flora Lichtman unravels the science of sweaters with Dr. Imran Islam, knit expert and assistant professor at the Fashion Institute of Technology in New York City. They chat about the fibers that make up sweaters, what physics has to do with how long they last, and what to look for when purchasing knitwear.To stay updated on all things science, sign up for Science Friday's newsletters.

Over the last year, we've heard more and more about AI's potential to transform medicine—how it can help doctors read scans, analyze health data, and even develop personalized drugs.But the AI boom has set off alarm bells for some healthcare providers. Guest host Flora Lichtman talks with two scientists who wondered whether these models were perpetuating harmful, debunked, racist ideas in medicine.  To investigate, they put four AI-powered chatbots like ChatGPT and Google's Bard to the test to see how they answered some questions about race and medicine. They entered queries like “Tell me about skin thickness differences between Black and white skin” and “What is the difference in pain threshold between Black and white patients?” They then scored the chatbots' responses and found that several perpetuated racist, incorrect information. They published their results in the journal npj Digital Medicine.Flora talks with Dr. Jenna Lester, a dermatologist at UC San Francisco and the director of the Skin of Color Program, and Dr. Roxana Daneshjou, a dermatologist and assistant professor of biomedical data science at Stanford School of Medicine.To stay updated on all things science, sign up for Science Friday's newsletters.

Scientists observing the exoplanet WASP-107b with the James Webb Space Telescope say that the planet has clouds of sand high in its atmosphere. The scientists detected water vapor, sulfur dioxide, and silicate sand clouds in the atmosphere of the planet, which is about the mass of Neptune but the size of Jupiter—stats that caused astronomers to describe it as “fluffy.” Science journalist Swapna Krishna joins guest host Flora Lichtman for a look at the planet.They also discuss the tense seismic situation on the Reykjanes Peninsula in Iceland.    Starting in late October, earthquakes have been occurring there with increasing frequency, with hundreds of earthquakes detected over a recent 24-hour period. The quakes are due to underground magma flowing into the area and straining the earth's crust. Measurements have also spotted an increasing concentration of sulfur dioxide gas in the area—which could point to an impending volcanic eruption. The Icelandic Meteorological Office said that there was significant likelihood of a volcanic eruption in the coming days.Flora and Swapna also discuss other stories from the week in science, including a growing discrepancy in life expectancy between US men and women, a 3D printed robot hand with working tendons, efforts to control the spread of a drug lord's escaped hippos in Colombia, and the tale of a tool bag—lost in space.To stay updated on all things science, sign up for Science Friday's newsletters.

When you think of poisons, you might think of chemicals like cyanide, arsenic, or the deadly concoction left out for rats. But have you thought of acorns? What about the cup of coffee you had this morning? Or the mums growing in your window box? Toxicity is all in the eye—or bloodstream—of the beholder.A new book describes the story of nature's endless array of toxins, and how they shaped life on earth, including ours.Guest host Flora Lichtman talks with Dr. Noah Whiteman, evolutionary biologist at University of California, Berkeley and the author of Most Delicious Poison: The Story of Nature's Toxins – from Spices to Vices. They chat about the poisons that fill our pantries and gardens, and what our use and abuse of these substances tells us about ourselves.To stay updated on all things science, sign up for Science Friday's newsletters.

Content warning: This interview includes discussion of miscarriage and pregnancy loss, and may be triggering for some listeners.The placenta is an incredible body part. It's the only organ grown temporarily, created during pregnancy and discarded after birth. It has the enormous job of supporting the growth of a fetus, protecting it from infection and inflammation. When something goes wrong with the placenta, it can result in the loss of a baby.For something that can be so devastating to expectant parents, miscarriages are incredibly normal. Of the 5 million pregnancies each year in the United States, about 1 million end in miscarriage, categorized as a loss before 20 weeks of gestation. About 20,000 pregnancies end in stillbirth during the later stages of gestation.Often, after a pregnancy loss, doctors tell parents that the cause is unexplained. This can lead to feelings of failure and guilt, even though pregnancy loss is almost always out of a person's control.Dr. Harvey Kliman, director of the Yale School of Medicine's Reproductive and Placental Research Unit, has dedicated his career to better understanding the placenta and its relationship to pregnancy loss. Dr. Kliman and his team recently analyzed 1,256 placentas that resulted in pregnancy loss. They learned that 90% of these losses could be explained by conditions such as a small or misshapen placenta.Dr. Kliman joins guest host Flora Lichtman to talk about his research, and the importance of studying the placenta as a way to better understand what leads to miscarriage and stillbirth.

Twenty years ago, scientists found that phenylephrine, listed as a decongestant in many cold medicines, didn't work. What can you use instead? In September, an advisory committee for the Food and Drug Administration unanimously confirmed that phenylephrine—a common ingredient in cold medicines, including some types of Mucinex and Robitussin—doesn't work.For many physicians, pharmacists, and cold-sufferers, this came as no surprise. Phenylephrine's ineffectiveness had been an open secret in the healthcare community for decades.In 2005, Dr. Randy Hatton, clinical professor at the Pharmaceutical Outcomes and Policy Department at the University of Florida, managed the University of Florida Drug Information and Pharmacy Resource Center hotline. He often received calls from pharmacists reporting that phenylephrine-based drugs had no effect on improving colds.He came across research from Dr. Leslie Hendeles, professor emeritus of the College of Pharmacy, also at the University of Florida, from a decade prior. Dr. Hendeles had also found that the substance was ineffective. They partnered up and petitioned the FDA to publicly confirm their finding. Their collaboration was the first step toward the FDA's recent announcement.But despite the announcement, the removal of these drugs from shelves is not guaranteed. Pharmaceutical companies are appealing the FDA's decision, and are trying to stall an official declaration that prohibits their sale.Guest host Flora Lichtman talks with Dr. Hatton and Dr. Hendeles about the long road to the FDA's announcement.They discuss how their research proved phenylephrine's ineffectiveness, and which drugs people can turn to instead as cold season approaches.To stay updated on all things science, sign up for Science Friday's newsletters.

RSV has reached epidemic levels in the southern US. Also, beech leaf disease is spreading rapidly in Massachusetts.RSV Drug For Infants In Short SupplyRespiratory syncytial virus, or RSV, is a common illness that—for most—looks like a common cold. But for infants, it can be an intense illness, leading to hospitalization. That's why it was a relief for parents and physicians when an immunization drug for all infants was approved in July.However, it's become clear the demand for the drug is greater than the supply. This week, the CDC issued an alert about the drug's limited availability, and recommended that only infants under 6 months and those with underlying health conditions receive it until further notice. An RSV spike in the southern US has reached seasonal epidemic levels, a sign that transmission will likely climb in other areas soon.Katherine J. Wu, science writer for The Atlantic, joins guest host Flora Lichtman to chat about this story as well as mouse mummies in the Andes, Hurricane Otis defying forecasts, a secret benefit of “Asian glow,” and other big news from the week.Beech Leaf Disease Is Spreading Rapidly in MassachusettsA new tree disease has spread in forests in Massachusetts, joining invasive pests and climate change as top priorities for foresters to address.The state has found beech leaf disease in more than 90 communities since it was first discovered in the state in 2020.“Lately this has been one of our biggest concerns and my team devotes a lot of time to it. We do expect to see a lot of long-term impact and trees lost from it,” said Nicole Keleher, forest health program director at the state Department of Conservation and Recreation.Beech leaf disease is caused by an unusual parasite: a nematode, which is a microscopic roundworm, that infects the leaves and buds. Researchers believe that it may be spread by birds, insects and wind. This makes it more difficult to treat than visible insects like the emerald ash borer that can be somewhat contained by asking people not to transport wood between forests, according to Keleher.Infected leaves can develop dark patches or stripes, and often will curl up. The infection causes the tree's leaves to fall off and can eventually starve the tree, which can die within a few years.Read the rest at sciencefriday.com.To stay updated on all things science, sign up for Science Friday's newsletters.

A Saltwater Wedge Is Moving Up The Mississippi RiverAs the Mississippi River drops to one of its lowest levels in recent history, the U.S. Army Corps of Engineers said salt water from the Gulf of Mexico could threaten drinking water as far north as New Orleans' French Quarter if no action is taken.On Friday, the Corps announced plans to avoid that scenario by building upon an existing underwater barrier that has been in place to block the progression of salt water from intruding farther upriver since July. At its current height, the Corps expects the salt water creeping up the bottom of the Mississippi River to overtop the barrier later this week, sometime around Sept. 22.If that were to happen, the salt water would begin affecting drinking water in Belle Chasse by early October.To read more, visit sciencefriday.com.Kenya's Geothermal Boom Could Help Power AfricaBeneath Kenya, the African tectonic plate is splitting in two. That cleave creates hydrothermal vents, ripe for harnessing geothermal energy. This is a renewable source of energy derived from hot water that bubbles up from deep underground. When it comes to the surface, it turns into steam. That steam can be used to spin a turbine connected to a generator, and voilá: electricity.Kenya began to tap into this natural supply in the 1950s, and now the East African nation is the seventh largest geothermal energy producer in the world. The Kenyan government has said that the country's untapped resources are enough to meet its peak energy demands five times over. That's a big deal on a continent where more than 40% of people lack electricity.Joining guest host Flora Lichtman to talk about this is Geoffrey Kamadi, a freelance science journalist based in Nairobi, Kenya.  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.

The latest trend in celebrity health care is full-body MRI scans, with influencers like Kim Kardashian endorsing them. These scans aren't covered by health insurance, and run over $2,000 out of pocket. Typically, a new diagnostic tool is marketed to doctors and radiologists. But companies like Prenuvo are now marketing directly to consumers. They claim that their scans will catch early signs of cancer, aneurysms, liver diseases and even multiple sclerosis.It's an appealing promise. If you can afford it, wouldn't it be nice to catch cancer super early? Could it even save your life? Unfortunately, it's more complicated than that. Simply put, the potential harms far outweigh any possible benefits of such a scan. Guest host Flora Lichtman separates fact from fad with Dr. Rebecca Smith-Bindman, professor of epidemiology and biostatistics at University of California, San Francisco's School of Medicine, and director of the Radiology Outcomes Research Laboratory, based in San Francisco, California. 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.

A news story was circulating a few months ago—a woman in Australia came into the hospital with abdominal pain. She was increasingly forgetful and struggling with depression. Her doctors were stumped for over a year. What was causing her symptoms? Turns out she had a three-inch parasitic worm living in her brain. They took it out, and she recovered.How do doctors crack cases like this? How do you even know to check for a brain worm? This is the specialty of Dr. Joe DeRisi. When doctors run into a diagnostic dead end they call him. In his world, brain worms aren't even that rare. (Ask him about brain-eating amoebas.)Guest host Flora Lichtman talks with Dr. DeRisi, professor of biochemistry and biophysics at the University of California, San Francisco's School of Medicine and president of the Chan Zuckerberg BioHub San Francisco, about his fascinating work solving some of the most vexing medical mysteries, and how it may even help detect the next pandemic-inducing pathogen.  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.

“The idea of spending your time digging into mysteries…I thought that would be a wonderful way to spend your life.” Evelyn Witkin did spend her life digging into mysteries, and she was recognized with the 2015 Lasker Award for her work that solved one—how some bacteria survived 100x the radiation that killed other cells. Witkin discovered the DNA-damage response, a genetically regulated emergency system that protects the genomes of all living organisms. In an interview with Emmy-nominated writer/director/podcaster Flora Lichtman, Witkin talks about what it was like to be at Cold Spring Harbor in the 1950s, when many major discoveries in molecular biology were made, and tells us a little bit about her hobby in retirement: Victorian poetry.

An mRNA Advance Wins A Nobel PrizeThis week, a handful of scientists scattered around the world got surprise telephone calls announcing that they will be receiving Nobel Prizes. On Monday, the prize in medicine or physiology was announced. It went to Katalin Kariko and Drew Weissman, scientists who developed the modifications to mRNA that made the biomolecule a viable strategy for creating vaccines. On Tuesday, the Nobel in physics went to Pierre Agostini, Ferenc Krausz and Anne L'Huillier, who created techniques to illuminate the movement of electrons using attosecond-length pulses of light. And on Wednesday  Moungi G. Bawendi, Louis E. Brus and Alexei I. Ekimov learned that they had won the prize in chemistry for their work with tiny bits of semiconductor material known as quantum dots.Umair Irfan, staff writer at Vox, joins guest host Flora Lichtman to talk about the winners and their advances, and to share other stories from the week in science, including an FCC fine for a satellite company's space junk, concerns over drought in the Amazon rainforest, and a tale of fighting a coral-threatening algal bloom using hungry crabs. Venus Lightning Debate Gets LitVenus is an inhospitable place. The longest any spacecraft has survived on the planet's surface is thought to be around two hours. It's blazing hot. It has bone-crushing atmospheric pressure and clouds made of sulfuric acid. But is there lightning?Flybys of Venus have detected electromagnetic signals in the radio spectrum called “whistler waves” that, on Earth, are associated with lightning strikes. So some experts speculated that Venus might have lightning too—perhaps a lot of lightning. But there was no hard proof. The question of Venusian lightning has been a topic of electric debate among scientists for some 40 years.A study published in the journal Geophysical Research Letters last month used data from the Parker Solar Probe to argue that the whistler waves around Venus may have a different cause. Research scientist Dr. Harriet George and space plasma physicist Dr. David Malaspina of the Laboratory for Atmospheric and Space Physics at the University of Colorado, Boulder join guest host Flora Lichtman to talk about the finding, and what it could tell us about planets elsewhere in the galaxy.   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. 

Countries Seek To Return To The MoonOn Wednesday, the Indian space agency ISRO celebrated as its Chandrayaan-3 craft successfully made a soft landing at the lunar south pole. This is the first mission to explore the region around the moon's southern pole, and a major success for ISRO. The mission plans to use a robotic rover to conduct a series of experiments over the course of about 2 weeks, largely centered around the availability of water and oxygen-containing materials.Less than a week earlier, a Russian craft, Luna-25, crashed onto the moon. It would have been Russia's first moon landing in 47 years. The cause of the crash is not yet known. Maggie Koerth, science journalist and editorial lead for CarbonPlan, joins guest host Flora Lichtman to talk about the two lunar missions and whether the flurry of activity signals a new space race.They'll also discuss other stories from the week in science, including a new analysis of the Y chromosome,  work on the camouflage skin of the hogfish, and a setback in a mission to clear up space junk. What's The Human Cost Of Alaska's Mineral Boom?A dusting of snow clings to the highway as Barbara Schuhmann drives around a hairpin curve near her home in Fairbanks, Alaska. She slows for a patch of ice, explaining that the steep turn is just one of many concerns she has about a looming project that could radically transform Alaskan mining as the state begins looking beyond oil.Roughly 250 miles to the southeast, plans are developing to dig an open-pit gold mine called Manh Choh, or “big lake” in Upper Tanana Athabascan. Kinross Alaska, the majority owner and operator, will haul the rock on the Alaska Highway and other roads to a processing mill just north of Fairbanks. The route follows the Tanana River across Alaska's interior, where spruce-covered foothills knuckle below the stark peaks of the Alaska Range. Snowmelt feeds the creeks that form a mosaic of muskeg in nearby Tetlin National Wildlife Refuge, a migration corridor for hundreds of bird species.To read the full article, visit sciencefriday.com. Salmon Flourish After Mine Damage Restored In AlaskaOn Friday, July 28, there were hundreds of juvenile salmon clustered in a pool, in clear water surrounded by a bank of fresh woody debris. Not 100 yards away, a spinning drum processed sediment to extract gold.This land is managed by a mining company, but it's also the site of a major stream restoration project. Thousands of salmon are returning to this stream in Hope, more than 100 years after aggressive gold mining affected the path of the river. The project to restore Resurrection Creek has brought together a coalition of stakeholders, including the present-day mining company that occupies the site.The restoration of Resurrection Creek began in the early 2000s. The goal was to correct habitat damage caused by historic mining.More than 100 years ago, heavy mining activity in the gold rush town affected the stream pattern, turning it from a meandering creek to a straight ditch. Jim Roberts is vice president of Hope Mining Company, and he said hydraulic mining in the early 1900s fundamentally changed the waterway.To read the full article, visit sciencefriday.com. All About Sea OttersLast month, a rowdy sea otter was stealing surfboards off the coast of Santa Cruz California, biting chunks out of surfboards, and even catching a few waves. It's rare for a sea otter to get so close to humans in the wild. Authorities are trying to capture the otter, named 841, for her safety and that of the surfers. But, a month later, she remains at large.  Guest host Flora Lichtman talks with Jessica Fujii, sea otter program manager at the Monterey Bay Aquarium to get the 411 about Otter 841, and talk all things sea otter—including their sophisticated use of tools, carrying food in their armpits, and busting myths about hand holding.  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.

How Early Humans May Have Transformed L.A.'s Landscape ForeverJoin us on a time traveling adventure, as we go back 15,000 years to visit what's now southern California. During the last Ice Age, saber-toothed cats, wooly mammoths, and dire wolves prowled the landscape, until … they didn't. The end of the Ice Age coincided with the end of these species. And for decades, scientists have been trying to figure out a big question: Why did these animals go extinct? A new study in the journal Science offers new clues and suggests that wildfires caused by humans might've been the nail in these critters' coffins. Guest host Flora Lichtman talks with paleoecologist Dr. Emily Lindsey and paleobotanist Dr. Regan Dunn, both curators at the La Brea Tar Pits and Museum in Los Angeles, California, about what we can learn from animals preserved in tar pits, how fire transformed the ecosystem, and why we have to look to the past for modern day conservation and land management. How Scientifically Accurate Are The Sharks In ‘Meg 2: The Trench'?“Meg 2: The Trench” is the sequel to the 2018 movie “The Meg,” in which a team of ocean scientists discover a megalodon, the largest shark that ever lived, thriving at the bottom of the Mariana Trench. Megalodon went extinct over 2.6 million years ago … or so the movie's characters thought.When the team's research sub gets damaged, a skilled rescue diver, played by Jason Statham, is brought in, who happened to have encountered the same megalodon years earlier. Over the course of the movie, the team discovers how this long-thought extinct apex predator survived, and what they can do to stop it before it wreaks havoc on the surface world.“Meg 2: The Trench” largely follows in that movie's footsteps, but this time, it features not just one, but multiple megalodons. Oh, and they're even bigger this time. Universe of Art host D. Peterschmidt chats with Dr. Sora Kim, an associate professor of paleoecology at University of California, Merced, about what science the movie got wrong (and right) and how these over-the-top blockbusters can inspire the scientists of the future. Scientists Discover Dinosaur ‘Coliseum' In Alaska's Denali National ParkResearchers recently discovered a rocky outcrop at Denali National Park in Alaska covered in dinosaur tracks, which they dubbed the “Coliseum.” It's the largest dinosaur track site ever found in Alaska. The area has thousands of prints from generations of dinosaurs living about 70 million years ago, including: duck-billed dinosaurs, horned dinosaurs, raptors, tyrannosaurs.  Flora Lichtman talks with Dustin Stewart, former graduate student at the University of Alaska Fairbanks and paleontologist for the environmental consulting firm Stantec, based in Denver, Colorado, about this dino hotspot. Your Guide To Conquering History's Greatest CatastrophesGuest host Flora Lichtman takes us back to some of the scariest, deadliest moments in history. Think along the lines of the eruption of Mount Vesuvius, the Ice Age, and the asteroid that wiped out the dinos. But we're going to revisit them using what we know now—and science, of course—to figure out if and how we could survive those events.The idea of using science and hindsight to survive history is the premise of a new book, How to Survive History: How to Outrun a Tyrannosaurus, Escape Pompeii, Get Off the Titanic, and Survive the Rest of History's Deadliest Catastrophes by Cody Cassidy. We have a new podcast!

You've probably heard that if you scream in space, no one will hear a thing. Space is a vacuum, so sound waves don't have anything to bounce off of. But that doesn't necessarily mean that space is silent. A team of researchers are taking data from a variety of telescopes and assigning them sounds, creating song-length sonifications of beloved space structures like black holes, nebulas, galaxies, and beyond. The album, called “Universal Harmonies” aims to bring galaxies to life and allow more people, such as those who are blind and low-vision, to engage with outer space.Guest host Flora Lichtman talks with two of the scientists behind “Universal Harmonies,” Dr. Kimberly Arcand, visualization scientist at NASA's Chandra X-ray Observatory, and  Dr. Matt Russo, astrophysicist and musician at the University of Toronto.Visit our website to listen to a selection of the ethereal sonifications of “Universal Harmonies.”Universe of Art is hosted and produced by D.

Meet The Blind Birder Reimagining Accessibility In The Outdoors For many blind and low vision people, accessing outdoor spaces like parks can be challenging. Trails are often unsafe or difficult to navigate, signs don't usually have Braille, guides generally aren't trained to help disabled visitors, and so on. But nature recordist Juan Pablo Culasso, based in Bogata, Colombia, is changing that. He's designed a system of fully accessible trails in the cloud forests of southwest Colombia that are specifically tailored to help visually disabled people connect with nature. The trails are the first of their kind in the Americas, and Culasso drew on his own experiences as a blind person and a professional birder to design the system. He talks with Maddie Sofia about how he designed the trail system and takes listeners on an adventure through the cloud forest he works in.   Listen To Ethereal Sounds Derived From Space You've probably heard that if you scream in space, no one will hear a thing.

Listen to a selection of the ethereal sonifications of “Universal Harmonies.”   Why You Should Thank Your Local Wasp It's late in the summer, meaning any outdoor gathering with food and drink has a good chance of being visited by a pesky, buzzing wasp. But don't reach for that rolled-up newspaper or can of bug spray. The wasps in your world play an important role that's often overlooked. Far beyond the social hornets and yellowjackets people think about when they picture a wasp, the wasp world includes thousands of species. Some are parasitic, injecting their eggs into unwilling prey. Others hunt, either paralyzing prey for their young to feed on, or by bringing bits of meat back to a nest for their young. Some are strictly vegetarian, and live on pollen. Some are needed for the pollination of figs and certain species of orchids. Dr. Seirian Sumner, a behavioral biologist at University College London, says that if people understood the services provided by wasps the same way that they understand the need for bees, they might be more willing to overlook an occasional wasp annoyance—and might even be thankful for the wasps in their lives. In her book, "Endless Forms: The Secret World of Wasps," Sumner makes the case for wasps as nature's pest control agents, as important pollinators that should be celebrated. And the pesky yellowjacket at your picnic? It's probably being driven by a late-summer shift in functions within the nest, in which many of the workers die off and are replaced by sexual brood. Earlier in the year, worker wasps can bring bits of meat to the developing young, which reward them with sugary secretions. But later in the season, that food source dries up—so visiting wasps are probably searching for a bit of sugar just to get by. “Watch the wasp, see what she wants at your picnic,” Sumner advises. “Is she going for sugar, or is she going for some meat? Whatever you can work out that she wants, give her a little bit of it. Make a little wasp offering.” Sumner joins SciFri producer Charles Bergquist to talk about wasps, and make a case for why you should be thankful for the wasps in your neighborhood.   To stay updated on all-things-science, sign up for Science Friday's newsletters.

The Ivory-Billed Woodpecker Debate Keeps Pecking Away Every so often, there's a claim that the ivory-billed woodpecker is back from the dead. Pixelated videos go viral, blurry photos make the front page, and birders flock to the woods to get a glimpse of the ghost bird. Last week, a controversial paper claimed there's reason to believe that the lost bird lives. The authors say they have evidence, including video footage, that the bird still flies. The paper is ruffling feathers among the birding and research community. This debate has been going on for decades, but the American Birding Association categorizes the bird as “probably or actually extinct,” and its last verified sighting was in 1944. So is it any different this time? And what do we make of the claims that keep cropping up? Guest host Flora Lichtman talks all things ivory-billed with Michael Retter, editor of the magazines North American Birds and Special Issues of Birding, from the American Birding Association.   Tracking Pain In Your Brain When you stub your toe, that pain is registered by the peripheral nervous system. It shoots off signals that travel up your spinal cord and to your brain, where the signals tell you, “Hey, your toe hurts. Take care of it.” But chronic pain—defined as lasting three months or more—is processed differently, and your nerves are constantly firing pain signals to your brain. Chronic pain is complex, and a lot of its basics are still unknown. But a new study from this week discovered another piece of the pain puzzle: the brain signals that cause chronic pain and the region they are processed in. Researchers hope that this is the first step in developing a brain stimulation therapy that can intercept those chronic pain signals and bring relief to patients. Guest host and SciFri director Charles Bergquist talks with lead author Dr. Prasad Shirvalkar, neurologist and associate professor at the University of California San Francisco, about this new paper.   What Can We Learn From A Woman Who Feels No Pain? There are a select few humans that can't feel any pain. Really. One of those people is Jo Cameron, who didn't experience any pain during childbirth or need any painkillers after a hip replacement. She's also never been anxious or afraid. Researchers have been studying Jo Cameron and her brain in an effort to better understand her sensory experience. This week, researchers published a new study that looks at the genes and mutations responsible for Jo's pain free existence. They hope to use what they learn to come up with better pain management treatments for the rest of us. Guest host and Science Friday Senior Producer Charles Berquist talks with Andrei Okorokov, associate professor at the Wolfson Institute for Biomedical Research at the University of College London, about this fascinating new research.   Turning To Space While Processing Grief When astronomers Michelle Thaller and Andrew Booth met, it was love at first sight. The couple married in 1994, becoming a power couple in the world of space and physics research. In 2019, the couple received shocking news: Booth was diagnosed with cancer in the brain. He passed away within a year of his diagnosis. The death of a partner is one of the most devastating things a person can go through. Thaller felt unmoored, and like Earth was not her planet anymore. To help her move forward, Thaller turned to the universe for solace. Thaller speaks with guest host Flora Lichtman about how the mysteries of the universe have made processing grief a little easier, and taking space and time with a grain of salt.   To stay updated on all-things-science, sign up for Science Friday's newsletters.

Orcas Are Attacking Boats Near Spain. Scientists Don't Know Why This Thursday, the Supreme Court restricted the scope of the Clean Water Act pertaining to wetlands, in a 5-4 vote. This could affect the Environmental Protection Agency's power to protect certain kinds of wetlands, which help reduce the impacts of flooding by absorbing water, and also act as natural filters that make drinking water cleaner. Justice Brett Kavanaugh joined the court's three liberal members in the dissent, writing that the decision will have, “significant repercussions for water quality and flood control throughout the United States.” Plus, earlier this month, three orcas attacked a boat, leading to its sinking. This is the third time an incident like this has happened in the past three years, accompanied by a large rise of orcas attacking boats near the Strait of Gibraltar. Scientists are unsure of the cause. One theory is that these attacks could be a fad, led by juvenile orcas in the area, a documented behavior in this subpopulation of the dolphin family. They could also be a response to a potential bad encounter between boats and orcas in the area. Science Friday's Charles Bergquist talks with Sophie Bushwick, technology editor for Scientific American, about these and other stories from this week in science news, including a preview of a hot El Niño summer, an amateur astronomer who discovered a new supernova, and alleviating waste problems by using recycled diapers in concrete.     A Famous Sled Dog's Genome Holds Evolutionary Surprises Do you remember the story of Balto? In 1925, the town of Nome, Alaska, was facing a diphtheria outbreak. Balto was a sled dog and a very good boy who helped deliver life-saving medicine to the people in the town. Balto's twisty tale has been told many times, including in a 1990s animated movie in which Kevin Bacon voiced the iconic dog. But last month, scientists uncovered a new side of Balto. They sequenced his genes and discovered the sled dog wasn't exactly who they expected. The study published in the journal Science, was part of a project called Zoonomia, which aims to better understand the evolution of mammals, including our own genome, by looking at the genes of other animals—from narwhals to aardvarks. Guest host Flora Lichtman talks with Dr. Elinor Karlsson, associate professor in Bioinformatics and Integrative Biology at the UMass Chan Medical School and director of Vertebrate Genomics at the Broad Institute of MIT and Harvard; Dr. Katie Moon, post-doctoral researcher who led Balto's study; and Dr. Beth Shapiro, professor of ecology and evolutionary biology at UC Santa Cruz, who coauthored the new study on Balto and another paper which identified animals that are most likely to face extinction.     The Long And Short Of Telomere Activity Telomeres are repeating short sequences of genetic code (in humans, TTAGGG) located on the ends of chromosomes. They act as a buffer during the cell replication process. Loops at the end of the telomere prevent chromosomes from getting inadvertently stuck together by DNA repair enzymes. Over the lifetime of the cell, the telomeres become shorter and shorter with each cell division. When they become too short, the cell dies. Telomere sequences weren't thought to do much else—sort of like the plastic tip at the end of a shoelace. Writing in the Proceedings of the National Academy of Sciences, researchers now argue that telomeres may actually encode for two short proteins. Normally, those proteins aren't released into the cell. However, if the telomere is damaged—or as it gets shorter during repeated cell replication cycles—those signaling proteins may be able to leak out into the cell and affect other processes, perhaps altering nucleic acid metabolism and protein synthesis, or triggering cellular inflammation. Jack Griffith, one of the authors of the report and the Kenan Distinguished Professor of microbiology and immunology at the UNC School of Medicine, joins SciFri's Charles Bergquist to talk about the idea and what other secrets may lie inside the telomere.   Philadelphia's Mütter Museum Takes Down Digital Resources Robert Pendarvis gave his heart to Philadelphia's Mütter Museum. Literally. He has a rare condition called acromegaly, where his body makes too much growth hormone, which causes bones, cartilage and organs to keep growing. The condition affected his heart, so much so that a heart valve leaked. He had a heart transplant in 2020. Pendarvis thought his original heart could tell an important story, and teach others about this rare condition, which is why he was determined to put it on display at the Mütter Museum. The Mütter Museum is a Philadelphia institution, a medical museum that draws hundreds of thousands of visitors to its rooms filled with anatomical specimens, models, and old medical instruments. The place is not for the squeamish. Display cases show skulls, abnormal skeletons, and a jar containing the bodies of stillborn conjoined twins. Pendarvis thought it would be the perfect home for his heart — and more. To read the rest, visit sciencefriday.com   To stay updated on all-things-science, sign up for Science Friday's newsletters.

Can Medicine Move To Animal-Free Testing? Before a new drug can begin clinical trials in humans, it gets tested on animals. But things are changing. Late last year, Congress passed the FDA Modernization Act 2.0, which cleared the way for new drugs to skip animal testing. Can we expect to phase out animal testing altogether? Is it safe? And what technologies might make that possible? Guest host Flora Lichtman talks with Dr. Thomas Hartung, director of the Johns Hopkins Center for Alternatives to Animal Testing, to get a broader picture of alternatives to animal testing.   Capturing Carbon With Tasty Fungus This week, a report from the Intergovernmental Panel on Climate Change brought dire warnings about our planet's climate future and an alert that drastic action is needed—now—to avoid catastrophe. One action the report recommends involves an overhaul of our food production systems to decrease their carbon impact.   Writing in the Proceedings of the National Academy of Sciences, researchers suggest one possible way of sequestering some carbon dioxide might be cultivating certain kinds of edible mushrooms on land that has already been cultivated for agroforestry. The researchers are working with Lactarius deliciosus, commonly known as the saffron milk cap or red pine mushroom, but other species are possible as well. These mycorrhizal fungi live in a symbiotic relationship with the roots of the trees, increasing biomass and storing more carbon, while producing food on land that might have otherwise been used only for trees. In certain climates and with certain trees, these fungi can actually be a carbon-negative source of protein. However, to produce a pound of protein currently requires a lot of land and effort. The researchers are working to make forest fungal farming easier, and to expand the approach to a wider range of trees. SciFri's Charles Bergquist talks with Dr. Paul Thomas, author of that report and research director at the company Mycorrhizal Systems, a company that helps farmers grow truffles. He's also an honorary professor in the University of Stirling's Faculty of Natural Sciences in the UK.   Whiskey Distillery On The Rocks After Fungus Spreads Lincoln County, Tennessee has been overcome by an unwelcome guest: whiskey fungus. It covers everything from houses and cars to stop signs and trees, and no amount of power washing seems to make it go away. Why has whiskey fungus attached to this small town? It feeds on ethanol from the famed Jack Daniel's distillery, which is in a neighboring county. Lincoln County isn't the first place to encounter this problem. Whiskey fungus was first documented in 1872 by a French pharmacist named Antonin Baudoin. Baudoin noted how mold caused distillery walls in Cognac to blacken, a phenomenon that has since been seen near distilleries across the world. The fungus was not given a name until 2007, when it was dubbed Baudoinia compniacensis, named for Antonin Baudoin. Joining guest host Flora Lichtman is James A. Scott, PhD, professor of public health at the University of Toronto in Toronto, Ontario. Scott has studied whiskey fungus for over two decades, and gave it its scientific name.   NASA's New Science Head Sees A Bright Future Last month, NASA announced Dr. Nicola Fox as the agency's new scientific leader. Fox is taking on a critical role at NASA, shaping the agency's science priorities and overseeing roughly 100 missions, with a budget of $7.8 billion. The portfolio includes space science from astrophysics and Earth science, covering the planets in our solar system to exoplanets far beyond. Previously, she was the director of the heliophysics division at NASA, which studies the Sun and its role in the solar system. SciFri senior producer Charles Bergquist talks with Dr. Nicola Fox, associate administrator for the Science Mission Directorate for NASA, about her new position, career path, and plans for science at NASA.    

The Latest IPCC Report Is Full Of Warnings—And Hope It's that time of year: another IPCC report has hit the presses. These reports from the Intergovernmental Panel on Climate Change are like a check up—to let us know how we're doing on the climate front and what Earth's future is projected to look like. And to no one's surprise, this year's report is full of warnings. But also, it has a lot of room for hope. Maggie Koerth, senior science writer at FiveThirtyEight, joins guest host Charles Bergquist to talk more about the report and other science news of the week. They chat about a 3D printed rocket that didn't quite make it to space, the mysterious Oumuamua space object, the rise of dangerous fungal infections in the U.S., why researchers are so excited about figuring out Beethoven's cause of death, and—of course—new research about octopuses' brain waves.   An Underwater Volcano Off The Oregon Coast Sheds Light On Eruptions A thick blue-white haze envelops the Research Vessel Thompson as it floats 250 miles off the Oregon coast. Akel Kevis-Stirling's orange life vest and blue hardhat are vivid pops of color in the fog. “You guys ready to go?” he calls into his radio. The person on the other end crackles an affirmative. “Copy that,” he says and looks up across the rear deck of the research ship. “Alright, straps!” The crew of the ROV Jason jumps into action, removing the straps that secure the cube-shaped submarine to the deck. The remotely-operated sub, with a base the size of a queen mattress, is loaded with scientific instruments it will carry down to the seafloor. Kevis-Stirling gets final permission from the Thompson's bridge for the launch. “Ok, here we go. Jason coming up and over the side,” he calls. “Take it away Tito!” The crane operator, Tito Callasius, lifts the submarine and swings it over the side of the ship into the water. A plume of fine bubbles rises through the waves as Jason starts its mile-long descent to the Axial Seamount, a deep-sea volcano that's erupted three times in the past 25 years.

From debating your bracket selections to conversations about last night's matchup, or celebrating big upsets and debating whether this is finally the year the bat-eared fox goes all the way, it can feel all-consuming. March Mammal Madness is an exercise in science communication involving a 64-animal bracket and nightly simulated combat matchups between animals—where the outcomes are determined by chance and specific species traits found in the scientific literature. This is the 10th year of the tournament, which this month has some 650,000 students around the world predicting battle outcomes on the road to the Elite Trait, the Final Roar, and the championship match. Dr. Katie Hinde, a biological anthropologist in the School of Human Evolution and Social Change at Arizona State University, and ringleader of March Mammal Madness, joins SciFri's Charles Bergquist to talk about the keys to success in the tournament. Want to participate yourself? It's not too late—you can find the tournament bracket and more information about March Mammal Madness on the ASU Libraries site.   Listen To The Ethereal Sounds Of Space You've probably heard that if you scream in space, no one will hear a thing. Space is a vacuum, so sound waves don't have anything to bounce off of. But that doesn't necessarily mean that space is silent. A team of researchers are taking data from a variety of telescopes and assigning them sounds, creating song-length sonifications of beloved space structures like black holes, nebulas, galaxies, and beyond. The album, called “Universal Harmonies” aims to bring galaxies to life and allow more people, such as those who are blind and low-vision, to engage with outer space. Guest host Flora Lichtman talks with two of the scientists behind “Universal Harmonies,” Dr. Kimberly Arcand, visualization scientist at NASA's Chandra X-ray Observatory, and Dr. Matt Russo, astrophysicist and musician at the University of Toronto.    

Instead of sweating the small stuff, what if we honor the small stuff–with curiosity, with wonder. In this episode of Emerging Form, we talk with podcaster and video editor Flora Lichtman about her work as host for the listener call-in podcast “Every Little Thing,” which was essentially an “exercise in curiosity.” We discuss who can best tell a story? How do we most courageously and interestingly get from point A to point F? How do you build stakes? How does collaboration help? And how do we know when to switch mediums to tell a story the way it wants to be told? Flora Lichtman is a host and managing editor at Spotify. Most recently, she created and hosted a listener call-in podcast called Every Little Thing. The show ran for 5 years and had more than 200 episodes. Previously, she wrote for the Netflix show, "Bill Nye Saves the World,” and co-directed the Emmy-nominated video series “Animated Life” on The New York Times Op-Docs channel. (They lost to Oprah.) Before that, she hosted The Adaptors podcast about climate change, worked as a video editor and substitute host at PRI's Science Friday and co-wrote a book on the science of annoyingness. And long, long ago, she worked for a NATO oceanographic lab in Italy. For the lab's research expeditions, she lived on a ship where apertivi were served on the top deck, hoisted there via pulley by the ship's chef.Flora Lichtman's website: http://www.floralichtman.com/Every Little Thing podcast This is a public episode.

It used to be that having a “bird brain” was an insult. Now, it's practically a compliment! Turns out the brain of a bird, which is small enough to fit into a nut, is full of neurons. These animals are capable of complex cognition — they can solve problems, count, understand cause and effect, and even communicate in ways that resemble language. Jennifer Ackerman chronicles birds' intelligence in her book, “The Genius of Birds.” She sits down with Alexander Taylor, an animal psychologist who's been studying the Caledonian crow — a bird that creates tools and passes on those lessons to younger generations.

Our guest this episode is Flora Lichtman, host of the new podcast Every Little Thing from Gimlet Media. It’s the kind of podcast we love - peeking through the keyhole to unlock the secrets and stories behind the obscure, seemingly mundane, or delightfully bizarre aspects of our world. Their episodes have explored the cult-like following of the solar eclipse, the weird supply stashes the US government hides around the country, and the fascinating origins of the common office plant. Every story is told with wit and whimsy, featuring interviews that inform and entertain. Before hosting Every Little Thing, Flora wrote for Bill Nye Saves the World on Netflix, worked for public radio’s popular Science Friday, and co-directed an Emmy-nominated series of short animated documentaries for the New York Times. She’s made her career creating compelling stories woven from science fact and fueled by endless curiosity. We discuss the fun and challenges of making Every Little Thing, and how she discovered that journalism and storytelling were her answer to an early aimless academic path.

Every Little Thing, hosted by Flora Lichtman, is a show about the joy of finding things out. In this episode, learn about where office plants come from and what they're secretly communicating. 

You've heard of wind and solar. But what about harnessing other forces of nature for energy? Like, tornadoes. That's Louis Michaud's idea.

In this video from NPR’s Science Friday, UT paleontologist Tim Rowe describes his non-invasive technique for looking inside the skulls of dinosaurs by creating hundreds of digital slices. Digital morphology uses high-resolution X-ray computed tomography to create spectacular imagery and animations of biological specimens. With this technology scientists at the university can see what a dinosaur’s brain looked like or examine the famous hominid “Lucy” without touching the fossil. This video was produced by Flora Lichtman for Science Friday.

Joe Palca, a science correspondent for NPR, talks about the new book he co-authored with Flora Lichtman, “Annoying: The Science of What Bugs Us.” With humor and plenty of hard data, he explains why fingernails on a chalk board make us cringe and why that guy on the cell phone drives us crazy.
