Radiolab

When no one seems to be listening, how far do you go to be heard? In December 2008, George W. Bush made a surprise visit to Baghdad for a press conference. And at the very end of his remarks, a shoe came flying past his head.  It was “the shoe heard around the world,” and countless jokes and memes ensued.  But in the pandemonium, many missed the story of the man at the center: Muntadhar Al-Zaidi, a weary journalist trying to get the world to see the Iraq War in a different light. Even fewer people know what happened to him after.  Nearly two decades later, Radiolab reporter Sarah Qari tracked Al-Zaidi down to learn the story of his life. What she found was a story about grief, anger, and the line where journalism ends and protest begins. Special thanks to Azmat Khan and Mustafa Salim.

Several years ago, in 2016, we told a story about Amy Pearl. For as long as she could remember, Amy loved meat in all its glorious cuts and marbled flavors. And then one day, for seemingly no reason, her body wouldn't tolerate it.  No steaks. No brisket. No weenies. It made no sense: why couldn't she eat something that she had routinely enjoyed for decades?  It turned out Amy was not alone. And the answer to her mysterious allergy involved maps, a dancing lone star tick, and a very particular sugar called Alpha Gal.  In this update, we discover that our troubles with Alpha Gal go way beyond food. We go to NYU Langone Health hospital to see the second ever transplant of a kidney from a pig into a human, talk to some people at Revivicor, the company that bred the pig in question, and go back to Amy to find out what she thinks about this brave new world. The original episode was reported by Latif Nasser, and produced by Annie McEwen and Matt Kielty. Sound design and scoring from Dylan Keefe, Annie McEwen, and Matt Kielty. Mix by Dylan Keefe with Arianne Wack. The update was reported and produced by Sarah Qari. It was sound designed, scored, and mixed by Jeremy Bloom. LATERAL CUTS: How does a tick bit can cause a red meat allergy? - An episode from our friends over at Science Friday, who had a recent conversation with the researcher who discovered the connection, decades ago.   Support Radiolab by becoming a member today at Radiolab.org/donate.    Sign up for our newsletter!!

In an episode we first ran back in 2014, we explore how a sunken nuclear submarine, a crazy billionaire, and a mechanical claw gave birth to a phrase that has hounded journalists and lawyers for 40 years and embodies the tension between the public's desire for transparency and the government's need to keep secrets.   Whether it comes from government spokespeople or celebrity publicists, the phrase “can neither confirm nor deny” is the perfect non-denial denial. It's such a perfect deflection that it seems like it's been around forever, but reporter Julia Barton takes us back to the 1970s and the surprising origin story of what's now known as a “Glomar Response.” With help from David Sharp and Walt Logan, we tell the story of a clandestine CIA operation to lift a sunken Soviet submarine from the ocean floor and the dilemma they faced when the world found out about it. It's an episode we first released in 2014, but given some things in the news recently, it resonated with us again. In the 40 years since that operation, the Glomar Response has become boilerplate language from an array of government agencies. With help from ProPublica editor Jeff Larson and NPR's Dina Temple-Raston, we explore the implications of this ultimate information dodge. ACLU lawyer Jameel Jaffer explains how it stymies oversight, and we learn that, even 40 years later, governmental secrecy can be emotionally painful. More information about Glomar: After 40 years, many of the details of Project Azorian are only now coming to light. The US government's default position has been to keep as much of it classified as possible. It took three years for retired CIA employee David Sharp to get permission to publish his account of Project Azorian. And FOIA played an indirect role in that, as Cold War historians got the CIA to release, in redacted form, an internal history of the mission. After that and a threat of legal action, Sharp was finally able to publish his manuscript in 2012. We mentioned conspiracy theories that have swirled around Project Azorian filling the void where official silence has reigned. One of them is promulgated in the 2005 book “Red Star Rogue” by Kenneth Sewell and Clint Richmond. They posit that the K-129 was taken over by rogue Stalinist KGB agents in order to start a nuclear conflict. But the conflict was to be between the US and China, as, according to the authors, the sub had powers to disguise its sonic signature as a Chinese Navy vessel. This book is the basis of the 2013 drama “Phantom,” which features Ed Harris and David Duchovny as Soviet military officers who sip vodka in a very un-Russian way. Russian Naval historians, like Nikolai Cherkashin, are not only insulted by this take on the cause of the K-129's demise, they say the true cause is much easier to pinpoint: They say an American vessel, possibly the USS Swordfish, collided with the Soviet submarine. Despite the fact that the US government has turned over many documents about Project Azorian and what it found to the Russian government, many in the Russian Navy stand by their theory that it was far too easy for the US to locate the K-129 on the bottom of the Pacific, given the technology of the time. According to these theories, Project Azorian was nothing more than an elaborate cover-up disguised as ... an elaborate cover-up. We can neither confirm nor deny that we exactly understand how that would have worked in practice or execution. It's one of the more solemn moments of the Cold War, and one that the Glomar Response helped keep a secret for a very long time.LATERAL CUTS:What Lies Beneath (https://radiolab.org/podcast/what-lies-beneath)  EPISODE CREDITS:  Reported by - Julia Barton Sign up for our newsletter!!

Lauren Brown gets goosebumps. A lot. Sometimes several times a day. When her partner, writer Carmen Maria Machado, noticed it...she couldn't stop thinking about it. Why does she get them in so many different situations? What's happening in her body and what does it mean? We take that question and run with it. We face chilly winds, sudden frights, and moments when the world seem to shift under your feet to figure out what the little bumps on our skin might be trying to tell us.   Special thanks to Rachel Gross, Gregory RupikEPISODE CREDITS: Reported by Maria Paz Gutierrez Produced by Maria Paz Gutierrez, Sindhu Gnanasambandan Fact-checking by Angely Mercado EPISODE CITATIONS: Website -  Institute for Advanced Consciousnehttp://www.advancedconsciousness.orgss Studies (advancedconsciousness.org) - If you want to check out more of the work Felix and Nicco are conducting.

Back in the 1950s, facing the threat of nuclear annihilation, federal officials sat down and pondered what American life would actually look like after an atomic attack. They faced a slew of practical questions like: Who would count the dead and where would they build the refugee camps? But they faced a more spiritual question as well. If Washington DC were hit, every object in the the National Archives would be eviscerated in a moment. Terrified by this reality, they set out to save some of America's most precious stuff. Today, we look back at the items our Cold War era planners sought to save and we ask the question: what objects would we preserve now? We first released this episode back in 2020, but with our big fourth of July – 250 years! – just around the corner, we thought it was a strange but profound reflection on what this whole America thing that we're celebrating… actually is.

Back in 2017, reporters Kristen Clark and David Conrad came to us with a story that dug into the difficult and often dark places discrimination creates. We start in Venice, Italy, where they meet gondolier Alex Hai. On the winding canals in the hidden parts of Venice, we learn about the nearly 1000-year old tradition of the Venetian Gondolier, and how the global media created a 20-year battle between that tradition and a supposed feminist icon.  We circled back to Alex in 2026, to find out where the canal of life ended up leading after our initial reporting, and we've included some heartbreaking and heartwarming updates on Alex's life at the end of this episode.  Special thanks to Alexis Ungerer, Summer, Alex Hai, Kevin Gotkin, Silvia Del Fabbro, Sandro Mariot, Aldo Rosso and Marta Vannucci, The Longest Shortest Time (Hillary Frank, Peter Clowney and Abigail Keel), Tim Howard, Nick Adams/GLAAD, Valentina Powers, Florence Ursino, Ann Marie Somma, Alex Overington, Jeremy Bloom and the people of Little Italy.  EPISODE CREDITS:  Reported by - David Conrad and Kristen Clark.

After reading something that said her menstrual cycle changes her brain each month, Senior Correspondent Molly Webster goes on a reporting mission to see if that's true, and, if so, how. This journey into sex hormones and the brain involves females and males, and exacting self-experimentation. It gets into PTSD, and ends with a new twist on self-care (hint: it's biological). And, it starts to reveal a sneaky truth: that each one of us is at the mercy of a crashing sea of chemicals inside of us – those things we call hormones.

In honor of Father's Day, here is a family friendly bonus episode from our kids' podcast Terrestrials.  What does it really mean to be a dad? In the animal world, fathers have long been painted as aggressive or absent. At best providers and protectors, but certainly not caregivers. And yet for every tale of a lion or chimp dad eating its own young (yikes!), there's another creature who tells a sweeter story.  Two HUMAN dads bring us on this DADventure: Dr. Eduardo Fernandez-Duque, who has spent decades studying owl monkey dads in the forests of Argentina, and Michael Feigelson, who once worried he wasn't cut out for the softer side of parenting.  They introduce us to seahorse dads who get pregnant, poison dart frog dads who give piggyback rides to their tadpoles, Darwin frogs who swallow their eggs to keep them safe, burying beetles who build "corpse cribs," jacana birds who do all the egg-sitting, and stickleback fish who construct intricate underwater nests for their young. Along the way, we learn that nature doesn't offer just one model of fatherhood. Alongside Mother Nature... there just might be a Father Nature, too. Special thanks to the Van Leer Foundation for the support of this episode.  Resources on Animal fatherhood Eduardo Duque's Owl Monkey Project: https://www.owlmonkeyproject.com/ An interview with Eduardo in Yale News Lauren O'Connell lab – frog behaviour Short explainer: frog parenting research Stickleback fish parenting study (Alison Bell) Alison Bell lab video Human fatherhood  Fathertime by Sarah Blaffer Hrdy ECM interview: evolution of “man the nurturer” Lee Gettler – biology of fatherhood (video) Lee Gettler article in Early Childhood Matters Darby Saxbe book: Dad Brain Darby Saxbe Article in Early Childhood Matters Talks, films & convenings Yale Conference on Fatherhood Live Recording of Yale Conference:  Fathers and Fatherhood: From Molecules to Modern Families Fathertime documentary Campaigns & global perspectives Equimundo's State of World's fathers report Men Care Changemakers Journey Parenting Out Loud (Elliot Rae) Terrestrials was created by Lulu Miller with WNYC studios.

A little while back, our friends over at On the Media released a gripping and immersive reporting series about FEMA, the agency that is supposed to be there for all of us in the wake of disaster. In American Emergency (https://zpr.io/MtrUmJU3yEMW), OTM investigates how the agency tasked with saving America became distrusted, despised… and defunded. Today we talk to On the Media co-host Micah Loewinger about how this project came out, what reporting went into making it happen, and play a couple of fun and truly surprising bits of the story that the OTM team uncovered. And it's a story that highlights the ideal and promise of good government, right alongside the frustration with bureaucracy and mismanagement, and of course the undercurrent of profound mistrust in governmental power.  As natural disasters are getting more extreme and less predictable, this series makes sense of that tangle, and provides a prescient peek into FEMA's future. Special thanks to On the Media (https://zpr.io/MtrUmJU3yEMW).  To hear Micah in person, talking more about the complex history of FEMA, join him on June 24th at WNYC's The Greene Space (https://wnyc.org/events/otm-fema).

One morning, Oliver Sipple went out for a walk. A couple hours later, to his own surprise, he saved the life of the President of the United States. In a story we reported back in 2017, we explain how in the days that followed, Sipple's split-second act of heroism turned into a rationale for making his personal life into political opportunity. What happens next makes us wonder what a moment, or a movement, or a whole society can demand of one person. And how much is too much?  Through newly unearthed archival tape, we hear Sipple himself grapple with some of the most vexing topics of his day and ours - privacy, identity, the freedom of the press - not to mention the bonds of family and friendship.  Special thanks to Jerry Pritikin, Michael Yamashita, Stan Smith, Duffy Jennings; Ann Dolan, Megan Filly and Ginale Harris at the Superior Court of San Francisco; Leah Gracik, Karyn Hunt, Jesse Hamlin, The San Francisco Bay Area Television Archive, Mike Amico, Jennifer Vanasco and Joey Plaster.EPISODE CREDITS: Reported by - Reported by Latif Nasser and Tracie Hunte Produced by - Produced by Matt Kielty, Annie McEwen, Latif Nasser and Tracie Hunte.

A couple summers ago, Radiolab reporter Alex Neason got out of the shower and almost stepped on her worst nightmare: an American Cockroach. It was flipped onto its back, struggling, and for a split second, Alex swears she felt the spiny tickle of its legs on the underside of her bare foot. And, like every other time she has come into contact with a roach, this sent her into a debilitating spiral of fear, anger, and disgust.  This week, Alex tries to understand what might be behind her fear, in the hopes she can overcome it. And in doing so, Alex learns more about these so-called pests than she could have ever wanted to.Special thanks to Jessica Ware, Timothy Marzullo, Alexandra Bell, and Changlu WangEPISODE CREDITS:  Reported by - Alex Neason Produced by - Jessica Yung and Annie McEwen with mixing help from - Jeremy Bloom Fact-checking by - Sophie Samiee and Edited by  - Pat Walters EPISODE CITATIONS: Articles -  American Cockroaches, Racism, and the Ecology of the Slave Ship (https://zpr.io/UNKsMz7ZaLvb) by Lindsay Garcia, Arcadia Books -   Pests: How Humans Create Animal Villains (https://zpr.io/6E5wJBM4Kvcv) by Bethany Brookshire The Cockroach Papers (https://zpr.io/CvKePYxEMEAW) by Richard Schweid Cockroach (https://zpr.io/UuEAjmfqKccQ)  by Marion Copeland Sign up for our newsletter!!

This episode makes three earnest, possibly foolhardy, attempts to put a price on the priceless. We figure out the dollar value for an accidental death, another day of life, and the work of bats and bees as we try to keep our careful calculations from falling apart in the face of the realities of life, and love, and loss.  In this story you'll hear references to some of the issues that were on our minds when it first came out in 2014: wars in the middle east, drug costs and health care practices. Even as the exact shapes of these issues have evolved over the past dozen years, we feel the underlying questions are relevant and timeless: What is life worth? What about the earth?

For most of human history, people went about their daily lives with a worm or two (or fifty) in their guts. Only in the past century, with pharmaceuticals and sanitation practices, have we made significant strides towards deworming the whole of humanity. And that's typically been thought of as a good thing, because having too many worms in your body can–quite literally–suck the life out of you. But is it possible to have… too few worms? Science wonders if deworming ourselves has actually led to an increase in certain chronic diseases. On this episode, we dive into Necator americanus, a.k.a. the American Hookworm, and its mysterious relationship with each of us. We trace the hookworm's 118-year journey from a demonized economic depressant, to its use as a desperate D.I.Y. immunosuppressant, to its potential as a medical treatment for a number of chronic diseases, everything from asthma to MS. We're bringing back two stories  from our 2009 episode Parasites plus new research on hookworms and autoimmune diseases, reported by Molly Webster Special thanks to Ethan Hein for the use of his remix of Mozart's Piano Concerto No. 21.

With all of the black-and-white moralizing in our world today, we decided to bring back an old show from 2011 about the little bit of bad that's in all of us...and the little bit of really, really bad that's in some of us.   Cruelty, violence, badness... in this episode we begin with a chilling statistic: 91% of men, and 84% of women, have fantasized about killing someone. We take a look at one particular fantasy lurking behind these numbers, and wonder what this shadow world might tell us about ourselves and our neighbors. Then, we reconsider what Stanley Milgram's famous experiment really revealed about human nature (it's both better and worse than we thought). Next, we meet a man who scrambles our notions of good and evil: chemist Fritz Haber, who won a Nobel Prize in 1918...around the same time officials in the US were calling him a war criminal. And we end with the story of a man who chased one of the most prolific serial killers in US history, then got a chance to ask him the question that had haunted him for years: why?

In 2017, Wayne Hsiung and a crew of animal rights activists from Direct Action Everywhere broke into a Utah pig farm run by Smithfield Foods, one of the largest pork distributors in the world. They were there to capture video of what they say were thousands of mistreated and abused animals kept in tiny metal cages barely bigger than their bodies. As they were leaving, they took two sick piglets out with them. Prosecutors in Utah charged Wayne with burglary and theft. What came next was the court battle that he wanted all along. During his trial, Wayne made a truly bizarre argument that forced the jury, and all of us, to stare straight at our complicated, sometimes uncomfortable relationship with animals. This week on the show, we grapple with the impossible question at the center of it: What is the value of a piglet?  Special thanks to Kim Nederveen Pieterse, Nathan Peereboom, Jo Eidman, Sam Kozloff, Rachel Gross, Alex Allaux, and Joan Schaffner.  EPISODE CREDITS:  Reported by - Sindhu Gnanasambandan and Jae Minard Produced by - Sindhu Gnanasambandan with help from - Pat Walters with mixing help from - Jeremy Bloom Fact-checking by - Diane A.

For much of history, tree canopies were pretty much completely ignored by science. It was as if researchers said collectively, "It's just going to be empty up there, and we've got our hands full studying the trees down here! So why bother?" But then around the mid-1980s, a few ecologists around the world got curious and started making their way up into the treetops using any means necessary (ropes, cranes, hot air dirigibles) to document all they could find. It didn't take long for them to realize not only was the forest canopy not empty, it was absolutely filled to the brim with life. You've heard of treehouses? How about tree gardens?!  This week, we bring you a story we first released in 2022. We journey up into the sky and discover forests above the forest. We learn about the secret powers of these sky gardens from ecologist Korena Mafune, and we follow Nalini Nadkarni as she makes a ground-breaking discovery that changes how we understand what trees are capable of.  P.S.

There's something rotten in the cows of Denmark. And Minnesota. And Wisconsin. And Idaho. What could cause a previously thriving herd of majestic dairy cattle to stop drinking water and start drinking … urine? A Danish farmer calls a special investigator, who takes one look at his farm and nopes the heck out of there, refusing to return, citing “bad energy” coming from something nearby … a big building covered in Viking runes.  It's not magic. It's an invisible force that's far more common. And yet deeply mysterious. This episode plunges producers Matt Kielty and Simon Adler knee-deep in a decades-old dairy farm controversy, rooted in a fundamental suspicion of the invisible streams of electrons that keep our world humming.

In an episode first aired back in 2025 on our sister show, Terrestrials, we take you on a musical journey all about beavers. Few mammals have a bigger positive impact on the planet than the beaver. With its bright orange buck teeth, the creature is an expert engineer that brings life wherever it waddles and even fights fires. Our story begins in the Bronx river, once known as the  “open sewer” of New York City. After some humans decide to clean it up, we meet one of the river's residents - José the beaver. We learn about the US government parachuting beavers out of planes into the mountains. And finally head to California where we discover how one beaver family saved acres of land from burning.  Special thanks to author Ben Goldfarb, Christian Murphy from the Bronx River Alliance and Dr. Emily Fairfax.  Terrestrials was created by Lulu Miller with WNYC Studios. This episode was produced by Ana González and sound-designed by Mira Burt-Wintonick. Our team includes Alan Goffinski, Joe Plourde and Tanya Chawla.

This week, in an episode we first aired in 2022, we flip the Disney story of life on its head thanks to a barrel of seawater, a 1970s era computer, and underwater geysers. It's the chaos of life. Latif, Lulu, and our Senior Producer Matt Kielty were all sitting on their own little stories until they got thrown into the studio, and had their cherished beliefs about the shape of life put on a collision course. From an accidental study of sea creatures, to the ambitions of Stephen J Gould, to an undercooked theory that captured the world's imagination, we undo the seeming order of the living world and try to make some music out of the wreckage. (Bonus: Learn how Francis Crick really thought life got started on this planet).

Doctor and special correspondent Avir Mitra takes Executive Editor Soren Wheeler, plus a live studio audience, on a journey from the operating room to inside the body to the farm to the sewers and back again—searching for answers to an alarming threat to humanity's existence as we know it: antibiotic resistance in bacteria.  This live show, performed in New York City and also in Little Rock, Arkansas, is part of a series we're doing with Avir that we are calling “Viscera.” Each event is a conversation that takes the audience on a journey into a quirk or question or mystery inside of us, and gives them a visceral experience of the viscera within us. The previous installment of the series was called “The Elixir of Life.” (https://radiolab.org/podcast/the-elixir-of-life)Special thanks to all of Little Rock Public Radio (especially Grace Zafasi and Jonathan Seaborn), Thomas Patterson, The Greene Space staff, CALS Ron Robinson Theater, Tom Philpott, Stephen Roach, Kate Shaw, Alex Wong, Maryn McKenna, and Kerri McClimen.If you are a patients or a doctor, and you are interested in phage therapy, please contact IPATH@ucsd.edu EPISODE CREDITS:  Reported by - Avir Mitra Produced by - Jessica Yung Sound design contributed by - Jeremy Bloom and Jessica Yung Fact-checking by -Natalie Middleton EPISODE CITATIONS: Videos - Check out the video from the Viscera live show (and a bonus Q&A with Bruce Stewart-Brown and Steffanie Strathdee) on Radiolab's YouTube (https://zpr.io/3BK9MqJYVKQA).

A strange brew that's hard to resist, even for a modern day microbe. In the war on devilish microbes, our weapons are starting to fail us. The antibiotics we once wielded like miraculous flaming swords seem more like lukewarm butter knives. But in this episode, originally released in 2015, we follow an odd couple, of a sort, to a storied land of elves and dragons. There, they uncover a 1,000-year-old secret that makes us reconsider our most basic assumptions about human progress and wonder: what if the only way forward is backward? Special thanks to Steve Diggle, Professor Roberta Frank, Alexandra Reider and Justin Park (our Old English readers), Gene Murrow from Gotham Early Music Scene, Marcia Young for her performance on the medieval harp and Collin Monro of Tadcaster and the rest of the Barony of Iron Bog. Can't get enough of that sweet, sweet antibiotic resistance content? Then you'll be over the moon about next week's release. It's the podcast cut of our most recent installment of our live show series called Viscera. This one features executive editor Soren Wheeler and Avir Mitra, and it's all about how our millenia's-long war against bacteria came to a tipping point in this modern age.

If a species is horrible enough, do we have the right to kill it forever? Seventy years ago, a nightmare parasite feasted on the live flesh of warm-blooded creatures in North America: the screwworm. That is, until a young scientist named Edward F. Knipling discovered a crucial screwworm weakness and hatched a sweeping project to wipe them out. Knipling's seemingly zany plan to spray screwworms out of planes all over the continent— with US taxpayer money— succeeded, becoming one of humanity's biggest environmental interventions ever.  Today, screwworms have been gone so long that none of us in North America even remember them. But now, they're coming back. And they're forcing us to ask: in an era of climate change and rapid mass extinction— should we kill off a species on purpose?  Special thanks to James P.

In this episode, we consider a creature we often don't think much about—the snail. And not just snails, but their sex lives. Which, as it turns out, is epic. There is persuasion and subterfuge, spaghetti penises and co-copulation. And this very surprising habit—erm kink—of making tiny arrows (actually!) and stabbing each other with them. Known as a “love dart,” these limestone daggers aren't just a strange trick of nature—they have a deep evolutionary purpose.  Special thanks to Menno Schilthuizen and Aaron Chase.EPISODE CREDITS:  Hosted by - Molly Webster Reported by - Molly Webster Produced by - Mona Madgavkar, Annie McEwen, Molly Webster Sound design contributed by - Mona Madgavkar, Annie McEwen Fact-checking by - Diane A.

In this episode, first aired in 2014, we examine three very different kinds of black boxes—spaces where we know what's going in, we know what's coming out, but can't see what happens in-between. From the darkest parts of metamorphosis to a sixty-year-old secret among magicians, and the nature of consciousness itself, we shine some light on three questions. But for each, we contend with an answerless space, leaving just enough room for the mystery and magic, always wondering what's inside the Black Box.

Before he was even born, Sarah and Ross Gray knew that their son Thomas wouldn't live long. But as they let go of him, they made a decision that reverberated through a world that they never bothered to think about. Years later, after a couple of awkward phone calls, they go on a quest and manage to meet the people and places for whom Thomas' short life was an altogether different kind of gift. We originally made this story back in 2015, but we wanted to play it again because we love that it brings a view of science that is redemptive, tender, and unexpected. Since we first released this episode, Sarah Gray wrote a book called A Life Everlasting (https://zpr.io/GVYisRaqe9d6), it's a memoir about Thomas that dives into the world of organ donation and medical science. She's also written a beautiful short story about shame called The Lacemaker Fairy Tale (https://zpr.io/Li5BMtfHmf92). And, right now she's working on a script for a movie called Raincheck.EPISODE CREDITS: Reported by - Jad Abumrad with help from - Latif NasserLATERAL CUTS - The Cathedral (https://radiolab.org/podcast/cathedral) The Immortal Life of Henrietta Lacks (https://radiolab.org/podcast/the-immortal-life-of-henrietta-lacks)  Signup for our newsletter!!

In the early 2000s, Sunil Nakrani felt stuck. Back then, websites crashed all the time. When Sunil noticed this, he decided he was going to fix the internet. But after nearly a year of studying the architecture of the web, he was no closer to an answer. In desperation, Sunil sent out a raft of cold emails to engineering professors. He hoped someone, anyone, could help him figure this out. Eventually, he learned that the internet could only be fixed if he paid attention to the humble honeybee. This is the story of the Honeybee Algorithm: How tech used honeybees to build the internet as we know it.Special thanks to John Bartholdi, John Vande Vate, Sammy Ramsey, James Marshall, Steve Strogatz, Duc Pham, and Heiko Hamann.We found out about this story thanks to our friends at AAAS, who run the one and only Golden Goose Awards. The award goes to government funded science that sounds trivial or bizarre, but goes on to change the world.

In this episode, we break the thermometer and watch the mercury spill out as we discover that temperature is far stranger than it seems. We first ran this episode in 2021: Five stories that run the gamut from snakes to stars. We start out underwater, with a species of snake that has evolved a devious trick for keeping warm. Then we hear the tale of a young man whose seemingly simple method of warming up might be the very thing making him cold. And Senior Correspondent Molly Webster blows the lid off the idea that 98.6 degrees Fahrenheit is a sound marker of health. In this episode, we break the thermometer and watch the mercury spill out as we discover that temperature is far stranger than it seems.

One spring evening in 2024, science journalist Rachel Gross bombed at karaoke. The culprit was a bleed in a fist-sized clump of neurons tucked down in the back and bottom of her brain called the Cerebellum. A couple weeks later, her doctors took a piece of it out, assuring her it just did basic motor control - she might be a bit clumsy for a while, but she'd still be herself. But after that surgery Rachel did not feel quite like herself. So she dove into the dusty basement of the brain (and brain science)  to figure out why. What Rachel found was a new frontier in neuroscience. We learn what singing Shakira on stage has to do with reaching for a cup of coffee  — and why the surprising relationship between those two things means we may need to rethink what we think about thinking.Special thanks to Warzone Karaoke at Branded Saloon, the Computer History Museum for their archival interview with Henrietta Leiner, either the choir “Singing Together, Measure by Measure” or the Louis Armstrong Department of Music Therapy which houses it, Daniel A.

Most of us spend some part of our lives feeling bad about ourselves and wanting to feel better. But this preoccupation is a surprisingly new one in the history of the world, and can largely be traced back to one man: a rumpled, convertible-driving California state representative named John Vasconcellos who helped spark a movement that took over schools, board rooms, and social-service offices across America in the 1990s. This week, we look at the rise and fall of the self-esteem movement and ask: is it possible to raise your self-esteem? And is trying to do so even a good idea?Special thanks to big thank you to the University of California, Santa Barbara Library for use of audio material from their Humanistic Psychology Archives and to their staff for helping located so many audio recordings. EPISODE CREDITS: Reported by - Heather Radke and Matt Kielty Produced by - Matt KietlyFlute performance and compositions by -  Ben BatchelderVoiceover work by - Dann FinkFact-checking by - Anna Pujol-Mazzini and  Angely Mercadoand Edited by  - Pat WaltersEPISODE CITATIONS:Articles - UCSB Humanistic Psychology Archive (https://zpr.io/HfVjUmvcVevE)Books - Selfie: How We Became So Self-Obsessed and What It's Doing to Us (https://zpr.io/eGRyqz9zNQHu) by Will Storr.

This episode, first aired in 2019, brings you the story of John Scott, the professional hockey player that every fan loved to hate.  A tough guy. A brawler. A goon. But when an impish pundit named Puck Daddy called on fans to vote for Scott to play alongside the world's greatest players in the NHL All-Star Game, Scott found himself facing off against fans, commentators, and the powers that be.  Was this the realization of Scott's childhood dreams? Or a nightmarish prank gone too far? Today on Radiolab, a goof on a goon turns into a parable of the agony and the ecstasy of the internet, and democracy in the age of Boaty McBoatface.Special thanks to Larry Lynch and Morgan Springer. Check out John Scott's "Dropping the Gloves" podcast (https://www.droppingthegloves.com/) and his book (https://www.simonandschuster.com/books/A-Guy-Like-Me/John-Scott/9781501159657) "A Guy Like Me". EPISODE CREDITS: Reported by - Latif NasserProduced by - Matt KieltyOriginal music and sound design contributed by -John Dryden, Thee Oh Sees, Weedeater and Bongzilla.Sign up for our newsletter!!

When neuroscientist Madeline Lancaster was a brand new postdoc, she accidentally used an expired protein gel in a lab experiment and noticed something weird. The stem cells she was trying to grow in a dish were self-assembling. The result? Madeline was the first person ever to grow what she called a “cerebral organoid,” a tiny, 3D version of a human brain the size of a peppercorn.In about a decade, these mini human brain balls were everywhere. They were revealing bombshell secrets about how our brains develop in the womb, helping treat advanced cancer patients, being implanted into animals, even playing the video game Pong. But what are they? Are these brain balls capable of sensing, feeling, learning, being? Are they tiny, trapped humans? And if they were, how would we know?Special thanks to Lynn Levy, Jason Yamada-Hanff, David Fajgenbaum, Andrew Verstein, Anne Hamilton, Christopher Mason, Madeline Mason-Mariarty, the team at the Boston Museum of Science, and Howard Fine, Stefano Cirigliano, and the team at Weill-Cornell. EPISODE CREDITS: Reported by - Latif Nasserwith help from - Mona MadgavkarProduced by - Annie McEwen, Mona Madgavkar, and Pat Walterswith mixing help from - Jeremy BloomFact-checking by - Natalie Middleton and Rebecca Randand Edited by  - Alex Neason and Pat WaltersEPISODE CITATIONS:Videos - “Growing Mini Brains to Discover What Makes Us Human,” Madeline Lancaster's TEDxCERN Talk, Nov 2015 (https://zpr.io/6WP7xfA27auR)Brain cells playing Pong (https://zpr.io/pqgSqguJeAPK)Reuters report on CL1 computer launch in March 2025 (https://zpr.io/cdMf8Yjvayyd) Articles - Madeline Lancaster: The accidental organoid – mini-brains as models for human brain development (https://zpr.io/nnwFwUwnm2p6), MRC Laboratory of Molecular Biology What We Can Learn From Brain Organoids (https://zpr.io/frUfsg4pxKsb), by Carl Zimmer.

In 1971, a red-headed, tree-loving astronaut named Stu ‘Smokey' Roosa was asked to take something to the moon with him. Of all things, he chose to take a canister of 500 tree seeds. After orbiting the moon 34 times, the seeds made it back to Earth. NASA decided to plant the seeds all across the country and then… everyone forgot about them. Until one day, a third grader from Indiana stumbled on a tree with a strange plaque: "Moon Tree." This discovery set off a cascading search for all the trees that visited the moon across the United States. Science writer, and our very own factchecker, Natalie Middleton (https://www.nataliemiddleton.org/) tells us the tale.Read Lulu's remembrance of Alice Wong for Transom.org: 13 questions I'll never get to ask Alice Wong (https://transom.org/2025/13-questions-ill-never-get-to-ask-alice-wong/). Check out Natalie's map to find your nearest moon tree on our show page (https://radiolab.org/podcast/the-travelers-how-moon-trees-hide-among-us)!Help us hunt for more moon trees.

As she -- and her friends — approached the age of 35, senior correspondent Molly Webster kept hearing a phrase over and over: “fertility cliff.” It was a short-hand term to describe what she was told would happen to her fertility after she turned 35 — that is, it would drop off. Suddenly, sharply, dramatically. And this was well before she was supposed to hit menopause. Intrigued, Molly decided to look into it — what was the truth behind this so-called cliff, and when, if so, would she topple? This story first premiered in “Thirty Something,” a 2018 Radiolab live show that was part of, Gonads, (https://radiolab.org/series/radiolab-presents-gonads)a six-episode audio and live event series all about reproduction and the parts of us that make more of us.

The standard view of evolution is that living things are shaped by cold-hearted competition. And there is no doubt that today's plants and animals carry the genetic legacy of ancestors who fought fiercely to survive and reproduce. But in this hour that we first broadcast back in 2010, we wonder whether there might also be a logic behind sharing, niceness, kindness ... or even, self-sacrifice. Is altruism an aberration, or just an elaborate guise for sneaky self-interest? Do we really live in a selfish, dog-eat-dog world? Or has evolution carved out a hidden code that rewards genuine cooperation?Sign up for our newsletter!!

A year ago we brought you a show called Shell Game where a journalist named Evan Ratliff made an AI copy of himself. Now on season 2 of the show, Evan's using AI to do more than just mimic himself — he's starting a company staffed entirely by AI agents, and making a podcast about the experience. The show is a smart, funny, and truly bizarre look at what AI can do—and what it can't. This week we bring you the first episode of Shell Game Season Two, Minimum Viable Company.

Our original host Jad Abumrad returns to share a new podcast series he's just released. It's all about Fela Kuti, a Nigerian musician who created a genre, then a movement, then tried to use his hypnotic beats to topple a military dictatorship. Jad tells us about the series and why he made it, and we play the episode that, for us at least, gets to the heart of the matter: How exactly does his music work? What actually happens to the people who hear it and how does it move them to action?You can find Jad's entire nine-part series, Fela Kuti: Fear No Man, on Apple or Spotify, or wherever you get your podcasts.EPISODE CREDITS: Reported by - Jad AbumradRadiolab portions produced by - Sindhu GnanasambandanSign up for our newsletter!!

Today on the show, we're bringing you an episode from Our Common Nature (https://link.podtrac.com/v7mx144d), a new podcast series where cellist Yo-Yo Ma and host Ana González travel around the United States to meet people, make music and better understand how culture binds us to nature. The series features a few familiar voices, including Ana González (host) and Alan Goffinski (producer), from our kids podcast, Terrestrials (https://link.podtrac.com/vysacqn1). About the episode: West Virginia is defined by its beauty and its coal, two things that can work against each other. Yo-Yo Ma felt this as soon as stepped foot in its hills.This episode explores how music and poetry help process the emotions of a community besieged with disaster and held together by pride and duty. We travel down the Coal River with third-generation coal miner Chris Saunders, who tells us how coal has saved and threatened his life. Poet Crystal Good shares her poetry, which channels her rage and love. And musician and granddaughter of West Virginia coal miners, Kathy Mattea, explains the beauty of belting out your home state in a chorus. The end of the episode finds host Ana floating down the New River with help from a group of high schoolers and Yo-Yo Ma. Listen to the full series Our Common Nature (https://link.podtrac.com/v7mx144d). Featuring music by Yo-Yo Ma, Dom Flemons, and Kathy Mattea and poetry by Crystal Good.EPISODE CREDITS: Radiolab Bits Produced - Anisa Vietze (Radiolab bits)Signup for our newsletter!!

Qasem Waleed is a 28-year-old physicist who has lived in Gaza his whole life. In 2024, he joined a chorus of Palestinians sharing videos and pictures and writing about the chaos and violence they were living through, as Israel's military bombardment devastated their lives. But Qasem was trying to describe his reality through the lens of the most notoriously confusing and inscrutable field of science ever, quantum mechanics. We talked to him, from a cafe near the Al-Mawasi section of Gaza, to find out why. And over the course of several conversations, he told us how this reality-breaking corner of science has helped him survive. And how such unspeakable violence actually let him understand, in a visceral way, quantum mechanics' most counter-intuitive ideas. Special thanks to Katya Rogers, Karim Kattan, Allan Adams, Sarah Qari, Soren Wheeler, and Pat WaltersEPISODE CREDITS: Reported by - Lulu MillerProduced by - Jessica Yungwith mixing help from - Jeremy BloomFact-checking by - Emily Kreigerand Edited by  - Alex NeasonEPISODE CITATIONS:Videos - A Brief History of Quantum Mechanics with Sean Carroll, The Royal Institution (https://www.youtube.com/watch?v=5hVmeOCJjOU)Introduction to Superposition, with MIT's Allan Adams (https://www.youtube.com/watch?v=lZ3bPUKo5zc)The Quantum Wavefunction, Explained (https://www.youtube.com/watch?v=sOI4DlWQ_1w)Articles - Read a selection of Qasem's published essays about his life in Gaza and the quantum world: I am stuck in a box like Schrodinger's in Gaza (https://zpr.io/ALDVi9E5bRt8) Israel has turned Gaza's summer into a weapon (https://zpr.io/YS4WK4hVQC5T)The Physics of Death in Gaza (https://zpr.io/hxsgxicVqPAd) Signup for our newsletter!!

When we think of China today, we think of a technological superpower. From Huawei and 5G to TikTok and viral social media, China is stride for stride with the United States in the world of computing. However, China's technological renaissance almost didn't happen. And for one very basic reason: the Chinese language, with its 70,000 plus characters, couldn't fit on a keyboard.Today, we tell the story of Professor Wang Yongmin, a hard-headed computer programmer who solved this puzzle and laid the foundation for the China we know today.Special thanks to Martin Howard.

A call to oceanographer Edie Widder about a fish with a very odd immune system quickly becomes something else: a dive into the deep sea, into a world of brilliant light. But down there, the light doesn't behave like light -- it sparkles and glows, but also drips, squirts, and dribbles. Today, find out how creatures make the light and how they use it, from hunting and hiding to maybe even … talking. And hear about a series of mysterious moments where Edie goes from studying the creatures to becoming one of them. EPISODE CREDITS: Hosted by - Molly WebsterReported by - Molly WebsterProduced by - Maria Paz Gutierrezwith help from - Molly WebsterFact-checking by - Diane A.

Love it or hate it, the freedom to say obnoxious and subversive things is the quintessence of what makes America America. But our say-almost-anything approach to free speech is actually relatively recent, and you can trace it back to one guy: a Supreme Court justice named Oliver Wendell Holmes. Even weirder, you can trace it back to one seemingly ordinary eight-month period in Holmes's life when he seems to have done a logical U-turn on what should be say-able.  Why he changed his mind during those eight months is one of the greatest mysteries in the history of the Supreme Court. (Spoiler: the answer involves anarchists, a house of truth, and a cry for help from a dear friend.)  Join us in an episode we originally released in 2021, as we investigate why he changed his mind, how that made the country change its mind, and whether it's now time to change our minds again.Special thanks to Jenny Lawton, Soren Shade, Kelsey Padgett, Mahyad Tousi and Soroush Vosughi.LATERAL CUTS:Content WarningFacebook Supreme CourtThe Trust EngineersEPISODE CREDITS: Reported by - Latif NasserProduced by - Sarah Qariwith help from - Anisa Vietze Signup for our newsletter!!
