Ever noticed how some people get to their 80s and 90s and continue to be healthy and active? They spend their days playing mahjong, driving to lunch, learning shuffle dancing, and practicing Portuguese. Those are “super agers,” seniors who stay fit well into old age. How do they do it? Is it luck or genetics? In this live broadcast, Hosts Flora Lichtman and Ira Flatow discuss the science of aging with two experts on the topic, cardiologist Eric Topol and neuroscientist Emily Rogalski.Guests:Dr. Eric Topol is an author, practicing cardiologist at the Scripps Clinic, and a genomics professor at the Scripps Research Institute in La Jolla, California.Dr. Emily Rogalski is a clinical and cognitive neuroscientist, and the director of the Healthy Aging & Alzheimer's Research Care Center at the University of Chicago.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

While there are a lot of dinosaur fossils, and a lot of plant fossils, the precise connection between the two has been something of a mystery. Now, researchers report that they've found what's called a cololite, fossilized gut contents, in the remains of a sauropod—a massive, long-necked plant-eater. The dino's last meal dates back 95 to 100 million years. Paleontologist Stephen Poropat joins Host Flora Lichtman to dig into the mysteries of a dinosaur's tummy.And, for prairie dogs, communication is key. The rodents' yips and barks can warn when danger is near—and not just to other prairie dogs. A new study suggests that birds called long-billed curlews are eavesdropping on this chatter to learn when a predator is lurking nearby. Using speakers and a taxidermied badger on wheels, ornithologists are untangling the social dynamics of black-tailed prairie dogs. Host Flora Lichtman talks with study author Andrew Dreelin about this eavesdropping behavior and what it means for conservation.Guests:Dr. Stephen Poropat is a paleontologist and deputy director of the Western Australian Organic and Isotope Geochemistry Centre at Curtin University in Perth, Australia.Andrew Dreelin is a research fellow with the Smithsonian Conservation Biology Institute and a PhD candidate at Northern Illinois University.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

A mysterious disease called acute flaccid myelitis (AFM) has been appearing in emergency rooms for about a decade. The disease has caused otherwise healthy children to lose the ability to move their arms and legs, and some become completely paralyzed. AFM is caused by a virus that's a cousin of the polio virus, earning it the nickname "the new polio.” Journalist and physician Eli Cahan joins Host Flora Lichtman to explain what doctors have been observing, the research efforts toward developing a vaccine, and what this emerging disease reveals about our readiness for future outbreaks and pandemics.Read Cahan's article about what fighting this “new polio” might look like as our healthcare infrastructure gets dismantled.And, learning more about some non-cancerous cells may help researchers better understand how cancer progresses. When you think about how cancer spreads in the body, you're probably thinking about cancer cells—they divide uncontrollably, form into tumors, and hide from the immune system. So, it makes sense that studying the behavior of these cells is critical to our understanding of cancer. But now, researchers are looking more closely at the non-cancerous cells that co-exist within tumors and the surrounding tissues. They make up what's called the “colocateome.” Taking this more holistic approach to cancer research may help explain why some treatments don't work for all patients, and eventually may lead to more effective therapies. To better understand this expanding field, Host Ira Flatow talks with Sylvia Plevritis, a Stanford University cancer researcher. Guests:Dr. Eli Cahan is a journalist and physician based in Boston, Massachusetts.Dr. Sylvia Plevritis is a professor of biomedical data science and radiology at Stanford University.Transcript is available on sciencefriday.com.

It's a precarious time for science in the United States. Federal funding is being slashed, career scientists are being laid off, and researchers are considering leaving to work abroad. On top of that, public trust in science and experts has declined. Besides acknowledging the federal attacks on science, a lot of scientists are also asking themselves: What are we doing wrong? How do we engage the public? And what could we do better?Joining Host Flora Lichtman to dig through these questions is Felice Frankel, a science photographer and chemical engineer at MIT. She's also the author of the upcoming book Phenomenal Moments: Revealing the Hidden Science Around Us, out this fall.Guest: Felice Frankel is a science photographer and a research scientist at the Massachusetts Institute of Technology in the department of chemical engineering.Transcript is available on sciencefriday.com.

South American cane toads were brought to Australia in 1935 to help eradicate native beetles that were destroying sugar cane crops. The toads didn't care much for the beetles, but they did spread across the coast of Queensland and beyond, with no natural predators to stop them. Their own deadly toxin devastated local reptiles along the way, and they now number over 200 million.Invasive biologists have long tried to curb Australia's cane toad population. The newest approach uses CRISPR gene-editing technology to create cannibalistic “Peter Pan” cane toad tadpoles: tadpoles that don't fully mature and instead feast on the tens of thousands of eggs that the toads produce.How was this approach developed, and how do these researchers think about making a potentially massive change to the ecosystem? Biologist Rick Shine, who has led the effort, joins Host Flora Lichtman to discuss it. Later, science journalist Elizabeth Kolbert talks about her experience reporting on similar monumental efforts to control nature—and what they say about us.Guests: Elizabeth Kolbert is a staff writer at The New Yorker and author of Under a White Sky: The Nature of the Future (Crown, 2021).

Millions of years ago, iguanas somehow got from North America to Fiji. Scientists think they made the trip on a raft of fallen vegetation. Also, the marine reptile's fossilized fetus is cluing paleontologists into the lives of ancient sea creatures.Ancient Iguanas Floated 5,000 Miles Across The PacificIf you picture iguanas, you might imagine them sunbathing on hot sand in the Caribbean or skittering around the Mojave Desert. But far, far away from where these iguanas are found is another group of iguanas living on the islands of Fiji and Tonga in the South Pacific—closer to New Zealand than the Americas. And it raises the question: How in the world did these iguanas end up all alone, on the other side of the ocean? In a study published in Proceedings of the National Academy of Sciences in March, scientists suggest that millions of years ago, iguanas hitched a ride on a raft and accidentally sailed all the way across the ocean before washing ashore and starting a new life. Host Flora Lichtman discusses the iguanas' intrepid adventure with lead author Dr. Simon Scarpetta, evolutionary biologist and assistant professor at the University of San Francisco in California.Meet Fiona, The Pregnant Icthyosaur FossilIn the Patagonia region of Chile, Torres del Paine National Park is a graveyard of ichthyosaurs—ancient, dolphin-like reptiles that roamed the oceans when dinosaurs dominated the land. Nearly 90 of these giant reptiles' fossils have been found amongst the glaciers. But the standout in the bone heap is Fiona, an ichthyosaur that lived 131 million years ago. She's in pristine condition, the only fully preserved ichthyosaur in Chile. And, she died pregnant. She's teaching paleontologists about the evolution of her species. And some of those findings were recently published in the Journal of Vertebrate Paleontology.

Scientists bring us a lab-grown chicken nugget and texturally accurate, plant-based calamari. We'll bite.There's a movement in the world of science to find alternatives to meat and dairy products that don't involve killing animals. Two avenues for this are by using animal cells in a lab, or going plant-based. Two breakthroughs in this field of food science were published in journals recently: the largest lab-grown chicken nugget and a plant-based fried calamari that tastes like the real thing.Producer Kathleen Davis joins Host Flora Lichtman to discuss these morsels of research and other science news of the week, including mandatory composting hitting the largest U.S. city, why human wounds heal slower than our primate cousins, and the disinfecting limitations of at-home washing machines. Transcripts for each segment will be available after the show airs on sciencefriday.com.

Being able to belt out a tune like Adele or Pavarotti is not just about raw talent. The best singers in the world have to work on their technique—like how to control their breath and develop the stamina to hit note after note for a two-hour concert. But pop stars and opera singers aren't the only vocalists who have figured out how to harness their voices for maximum impact.Death metal vocalists also train their voices to hit that unique guttural register. And those iconic screams are not as easy to master as they might seem.Vocal scientists at the University of Utah are now bringing death metal singers into the lab to try to understand how they make their extreme vocalizations. What they're finding is not only insightful for metalheads, but might also help improve treatment for people with some types of vocal injuries. Host Flora Lichtman talks with Dr. Amanda Stark, speech pathologist and vocology researcher at the University of Utah, and Mark Garrett, vocal coach and lead singer of the band Kardashev.Read the whole story at sciencefriday.com.Also, we share a follow-up to our story about seasonal allergies based on a listener's question about her family's allergies.Transcripts for each segment will be available after the show airs on sciencefriday.com.   Subscribe to this podcast.

It's zombie season! At least if you're watching the new season of the fungal thriller “The Last of Us,” airing right now on Max, which chronicles what happens after a fungus turns most of humanity into zombies.It's fiction for us, but for some organisms on the planet, it's more like a documentary. The fungus that zombifies humanity in the show is based on Ophiocordyceps, a real fungal group that infects ants, takes over their brains and bodies, and turns them into spore factories.But this isn't the only example of real-life zombies. Science writer Mindy Weisberger found a whole book's worth of stories about horrifying and creative zombies and zombie-makers that inhabit the Earth, which she writes about in Rise of the Zombie Bugs: The Surprising Science of Parasitic Mind-Control.Host Flora Lichtman sits down with Weisberger to talk about the creepy and inventive lifestyles of these parasites, and how studying these zombifiers can teach us about ourselves.Read an excerpt from Rise Of The Zombie Bugs.Transcripts for each segment will be available after the show airs on sciencefriday.com.  Subscribe to this podcast.

Research suggests that better understanding the psychological and neurological components of chronic pain may lead to better treatments.Chronic pain is remarkably common: Roughly 20% of adults in the US live with it. And people with chronic pain are more likely to have depression, anxiety, and substance abuse disorders. But this relationship between physical and mental health is not as straightforward as you might think, and there's still a stigma attached to neuro-psychological causes of chronic pain.The latest research suggests that untangling the connections between mind and body is a key part of developing better treatments for people with chronic pain. Now, a new psychological treatment called pain reprocessing therapy has shown initial success in eliminating back pain in research participants.Producer Shoshannah Buxbaum joins Host Flora Lichtman to share her reporting on the intersection of mental health and chronic pain.Transcript for this story will be available after the show airs on sciencefriday.com.

Researchers isolated one kind of cone in the eye and aimed lasers at it to allow subjects to see a super vibrant teal shade they call “olo.”Think about the colors of the world around you—the blue of a cloudless sky, the green of a new leaf, the blazing red of a tulip's petals. We see these colors because of the way our eyes work. But what if we could change how our eyes respond to light, and present them with light in a form they'd never encounter in the natural world? What would we see?This week, researchers reported in the journal Science Advances that by using precisely aimed laser light, they were able to selectively target just one of the three types of color-sensing cones in the human retina. The cone, dubbed “M” because it responds to medium wavelengths of light, is normally stimulated at the same time as cones that respond to longer wavelength reddish light, or shorter wavelength bluish light. But after mapping the location of the cones in several subjects' eyes, the researchers were able to target just the M cones with one specific wavelength of green laser light—a condition that would never exist in nature. The result, they say, is a highly saturated bluish-green teal color unlike anything in the real world. The researchers named their new color “olo.”Study author James Fong, a computer science PhD student at University of California Berkeley, and his advisor, Dr. Ren Ng, join Host Flora Lichtman to talk about the project, and the possibility of expanding the limits of human color perception.Transcript for this story will be available after the show airs on sciencefriday.com.

How will market uncertainty and a lack of federal support for climate efforts affect the future of clean energy in the United States? Plus, many wetlands are disappearing, but Louisiana's “accidental” Wax Lake Delta is growing—and informing coastal restoration techniques.$8 Billion Of Climate Tech Projects Were Canceled In 3 MonthsIn the first three months of the Trump administration, officials have been aggressive in cancelling climate change related efforts, from enacting layoffs at large agencies to withdrawing from the Paris Climate Agreement and rescinding federal funding for green research and infrastructure.Joining Host Flora Lichtman to break down the changes we're starting to see in climate policy and clean tech on the ground is Casey Crownhart, senior climate reporter at MIT Technology Review. They also talk about other science news of the week, including a Florida-based startup that's recycling solar panels, an update on the growing measles outbreak in the Southwest, signs of a US science brain drain, humanoid robot participants in the Beijing half marathon, and how bats manage to drink on the fly.In Louisiana, A Chance To Study A Successful, Growing WetlandAmid the rapid erosion of Louisiana's coast, something hopeful is happening where the Atchafalaya River meets the Gulf. A flow of sediment from a decades-old river diversion has accidentally given birth to new wetlands.While that small delta is dwarfed by what's washing away all around it, researchers have gained knowledge from Wax Lake Delta that could help save the rest of Louisiana's coast and contribute to a better understanding of wetland science across the globe.Read more at sciencefriday.com.Transcripts for each segment will be available after the show airs on sciencefriday.com.

With the help of cat owners, a new project investigates cats' biology and aims to link some of their behaviors to their genes.Calling all cat people: This one's for you. Despite humans' long history of welcoming felines into their homes and delis, research on cats lags far behind research on dogs. Now, scientists behind the project Darwin's Ark are working to close the cat gap by enlisting cat caretakers from across the country to submit a tuft of fur and answer a few questions about their feline's appearance, personality, and behaviors.Host Flora Lichtman talks about the project, as well as what we do and don't know about cat genetics, with Dr. Elinor Karlsson, chief scientific officer at Darwin's Ark, and director of the Vertebrate Genomics Group at the Broad Institute of MIT and Harvard Universities.Transcript for this segment will be available after the show airs on sciencefriday.com.

An evolving technology is changing the lives of people with paralysis: brain-computer interfaces (BCI). These are devices that are implanted in the brain and record neural activity, then translate those signals into commands for a computer. This allows people to type, play computer games, and talk with others just by thinking, allowing more freedom to communicate.For decades, this technology has looked like a person controlling a cursor on a screen. But this work has advanced, and in a recent breakthrough, a person with paralysis in all four limbs was able to move a virtual quadcopter with extreme precision by thinking about moving it with their fingers.Another area of BCI research involves speech. Recent work has shown promise in allowing people with vocal paralysis to “speak” through a computer, using old recordings to recreate the person's voice from before their paralysis.Joining Host Flora Lichtman to discuss the state of this technology, and where it may be headed, are Dr. Matthew Willsey, assistant professor of neurosurgery and biomedical engineering at the University of Michigan, and Dr. Sergey Stavisky, assistant professor of neurosurgery and co-director of the Neuroprosthetics Lab at the University of California, Davis.Transcript for this segment will be available after the show airs on sciencefriday.com.

Are traffic engineering decisions based on evidence-based research? Not as much as you might think.If you've seen a car crash on the side of the road, you might look at it and think that the person at fault is the driver. But how much blame should be shared by the people who designed those roads in the first place?Well, some traffic engineers are calling for the field to accept more blame for the crashes and the tens of thousands of annual fatalities that happen on our roads, including Dr. Wes Marshall, a professor of civil engineering at the University of Colorado Denver. In his book Killed By A Traffic Engineer: Shattering the Delusion that Science Underlies our Transportation System, he digs into the standards that have dictated traffic design for decades to find out exactly how much science they're based on. Spoiler alert: It's a lot less than you'd think.Host Flora Lichtman sits down with Dr. Marshall to talk about how we got to this point and what a safer version of our streets could look like.Transcript for this segment will be available after the show airs on sciencefriday.com.

The Webb Space Telescope picked up traces of dimethyl sulfide on planet K2-18b. On Earth, the molecule comes from microbes and phytoplankton. Also, researchers captured the first confirmed video of a colossal squid swimming in its natural habitat—almost 2,000 feet deep.Possible Signature Of Life Detected On Exoplanet—MaybeIn major galactic news, scientists may have detected possible signs of life on a planet right here in our galaxy. Is this one of the best hints we've gotten that alien life exists? Host Flora Lichtman gets into it with Anil Oza, the Sharon Begley Science Reporting Fellow at STAT and MIT. They discuss the latest in alien life, the Trump's administration cuts to the “indirect costs” of science funding, the largest map of a brain yet, and how salmon on anti-anxiety meds make bolder choices.A Colossal Squid Video? That's A Big DealThis week, scientists announced that they had captured the first confirmed video of a colossal squid in its natural habitat, recorded some 1,968 feet (600 m) below the ocean surface near the South Sandwich Islands. While there have been sightings of the colossal squid before, they have mainly been of individuals entangled with fishing equipment—and much of what is known about the elusive creatures comes from dead specimens.The video was captured by scientists on board the R/V Falkor (too) during an Ocean Census expedition searching for new marine life. As the remotely operated vehicle SuBastian descended towards the ocean floor, its cameras caught sight of a juvenile squid roughly one foot long (30 cm), and captured over a minute of high resolution video. The footage was later analyzed by experts and determined to be a colossal squid.Colossal squid are estimated to grow up to 23 feet (7 m) in length and can weigh as much as 1,100 pounds (500 kg), making them the heaviest invertebrate on the planet. They are not the same as the giant squid, an entirely different species, which can grow to be longer but are lighter and slimmer.Dr. Kat Bolstad, one of the squid experts the researchers sent their videos to for identification, joins Host Flora Lichtman to talk about the sighting.Transcripts for each segment will be available after the show airs on sciencefriday.com.

Imagine you're diving into a cell. You're paddling around in the cytoplasm, you're climbing up a mitochondria. If you're having a hard time picturing this, that's okay! There are professionals who do this for a living.We wanted to learn more from expert science interpreters, who take the results section of a research paper and translate it into something tangible, like a 40-foot dinosaur skeleton or a 3D animation of cellular machinery too small to see.At a live event in Salt Lake City in March, Host Flora Lichtman spoke with Dr. Janet Iwasa, head of the University of Utah's Animation Lab and director of the Genetic Science Learning Center; and Tim Lee, director of exhibits at the Natural History Museum of Utah, about how they bring these out-of-reach worlds to life.Transcripts for each segment will be available after the show airs on sciencefriday.com.

Bringing back Southwest peach orchards won't be easy, but researchers are on the lookout for remaining trees—and they need help. And, the newly discovered Lokiceratops is challenging paleontologists' understanding of how horned dinosaurs evolved and existed together. How A Navajo Plant Researcher Is Reviving A Desert PeachWhen you think of states known for their peaches, Utah might not be at the top of your list. But there is a variety—the Southwest peach—that grows in this arid landscape, and Native communities have cultivated this tree since the 1600s. But many of the orchards were intentionally destroyed by colonizers hundreds of years ago, and the remaining trees are now scattered across the region.A local scientist and member of the Navajo Nation is on a mission to track down Southwest peach trees so we can learn more about how these peaches are so well-suited to grow in the desert.At a live event in Salt Lake City in March, Host Flora Lichtman spoke with Reagan Wytsalucy, plant scientist and assistant professor at Utah State University Extension in San Juan County, Utah. She researches traditional Native American crops, including the Southwest peach.Meet Lokiceratops, A Giant Dinosaur With Blade-Like HornsThe Intermountain West is a dinosaur nerd's dream because it's such a hotspot for fossils. Some of the most famous dino fossils in the world, like T. rex, triceratops, and stegosaurus can be found in western North America. So, of course, Science Friday couldn't go to Salt Lake City, Utah, without digging into some dinosaur science.At a live event in Salt Lake City in March, Host Ira Flatow spoke with the scientists behind the discovery of Lokiceratops, a large dinosaur with impressive horns that was unveiled in 2024. Dr. Mark Loewen, vertebrate paleontologist at the University of Utah and the Natural History Museum of Utah; and Savhannah Carpenter, paleontologist and school outreach coordinator at the Natural History Museum of Utah, discuss how they figured out Loki was a new dinosaur, the process of describing and naming the fossil, and what it taught them about dino evolution.Transcripts for each segment will be available after the show airs on sciencefriday.com.  Subscribe to this podcast.

We are rounding up your questions about roads. What confounds you about traffic, or how interstates are laid out? Are there certain road design elements that ignite your road rage? Tell us about it: we've got a traffic engineer in the passenger seat this week, ready to answer your questions. Call us at (877) 4-SCIFRI or 877-472-4374.In this episode, utterances like “um,” “wow,” and “mm-hmm” aren't just fillers—they keep conversations flowing. Also, new research suggests the artificial sweetener saccharin could kill antibiotic resistant bacteria.Huh? The Valuable Role Of InterjectionsListen carefully to a spoken conversation and you'll notice that the speakers use a lot of little quasi-words—mm-hmm, um, huh? and the like—that don't convey any information about the topic of the conversation itself. For many decades, linguists regarded such utterances as largely irrelevant noise, the flotsam and jetsam that accumulate on the margins of language when speakers aren't as articulate as they'd like to be.But these little words may be much more important than that. A few linguists now think that far from being detritus, they may be crucial traffic signals to regulate the flow of conversation as well as tools to negotiate mutual understanding. That puts them at the heart of language itself—and they may be the hardest part of language for artificial intelligence to master.Read the rest of this article on sciencefriday.com.A Sweet New Treatment For Antibiotic Resistant Infections?Researchers have discovered that the artificial sweetener saccharin has powerful antimicrobial properties. A new study published in EMBO Molecular Medicine suggests that saccharin can actually kill antibiotic resistant bacteria by interfering with DNA replication and cell division. The researchers also concluded that, with the help of traditional antibiotics, saccharin could even be used as an effective wound treatment.Host Ira Flatow talks with study author Dr. Ronan McCarthy, professor in biomedical sciences and director of the Antimicrobial Innovations Centre at Brunel University of London.Transcripts for each segment will be available after the show airs on sciencefriday.com.

On Wednesday, the Senate Committee on Commerce, Science and Transportation heard testimony from Jared Isaacman, President Trump's nominee to lead NASA. During the confirmation hearing, Isaacman indicated a priority of sending humans to Mars—while maintaining the agency's plans to return people to the lunar surface.In response to a question from Senator Ted Cruz, Isaacman said “I don't think we have to make any tough trades here, Senator. I think if we can concentrate our resources at the world's greatest space agency, we don't have to make a binary decision of moon versus Mars, or moon has to come first versus Mars.” Senators questioned how a strategy involving both options would be possible under current funding levels, and stressed that a bipartisan law had codified the current approach of targeting the moon first, then Mars.The fate of the Artemis lunar exploration program has faced questions in the new administration. In his inaugural address, President Trump expressed a desire to send astronauts to Mars, but didn't mention the moon. Elon Musk, head of SpaceX and a favored advisor to the president, is in favor of prioritizing crewed Mars missions ahead of lunar programs. Under questioning, Isaacman repeatedly refused to say directly whether Musk had been present for his job interview with the President.Host Flora Lichtman talks with Senior Producer Charles Bergquist about the nomination and the path ahead for NASA. They also talk about other stories from the week in science, including the controversy over claims of a “de-extincted” dire wolf, advances in rapid bird flu sensors, and the detailed physics of a cup of pour-over coffee.Transcript for this segment will be available after the show airs on sciencefriday.com.

NASA is planning to decommission the International Space Station by the end of 2030. The ISS, which began operations in 2000, is reaching the end of its lifespan and has become costly to maintain. NASA selected SpaceX to construct a vehicle that would “de-orbit” the football field-sized station, pushing it down into the atmosphere where it'll burn up safely over the Pacific ocean.So what comes next? So far, NASA has awarded contracts to private companies including Axiom Space, Blue Origin, Northrup Grumman, and Starlab to support the research and development for commercial space stations which would help facilitate future research in orbit, among their own space tourism offerings. Next year, NASA will certify one or more of these companies to build at least one space station, where it'll then become one of many customers to purchase services from the new facilities.Loren Grush, space reporter at Bloomberg News, joins Host Ira Flatow to discuss who's in the running and how future space stations could differ from the one we know today. She also talks about her recent trip to the headquarters of Vast, one of the companies competing for this contract, to learn more about its cryptocurrency origins and its high-level recruitments from NASA and Apple.Transcripts for each segment will be available after the show airs on sciencefriday.com.
