Radiolab

This is an episode that first aired in 2018 and then again in the thick of the pandemic in 2020. Why? Because though Horseshoe crabs are not much to look at, beneath their unassuming catcher’s-mitt shell, they harbor a half-billion-year-old secret: a superpower that helped them outlive the dinosaurs, survive all the Earth’s mass extinctions, and was essential in the development of the COVID vaccines.  And what is that secret superpower? Their blood. Their baby blue blood.  And it’s so miraculous that for decades, it hasn’t just been saving their butts, it’s been saving ours too. But that all might be about to change.   Follow us as we follow these ancient critters - from a raunchy beach orgy to a marine blood drive to the most secluded waterslide - and learn a thing or two from them about how much we depend on nature and how much it depends on us.

Today, we go to a spot that may be one of the most philosophical places in the universe: the thymus, an organ that knows what is you, and what is not you. Its mood may be existential, but its role is practical — the thymus is the biological training ground where the body learns to protect itself from outside invaders (think: bacteria, coronaviruses). But this training is not the humdrum bit of science you might expect. It’s a magical shadowland with dire consequences.  Then, we’ll leave the thymus to visit a team of doctors who are using this organ that protects you as a way to protect someone… else. Their work could change everything. Special Thanks:  One thousand thanks to Hannah Meyer, Salomé Carcy, Josh Torres, and Cold Spring Harbor Laboratory for showing us a real-life (mouse) thymus for this episode. Special thanks also go to Diane Mathis and Kate Webb. Further reading: Wanna do a little light reading?

As our co-Hosts Lulu Miller and Latif Nasser are out this week, we are re-sharing the perfect episode to start the summer season! This one, which first aired in 2014, tells the strange story of a small group of islands that keeps us wondering: will our most sacred natural landscapes inevitably get swallowed up by humans? How far are we willing to go to stop that from happening? This hour is about the Galápagos archipelago, which inspired Darwin’s theory of evolution and natural selection. Nearly 200 years later, the Galápagos are undergoing rapid changes that continue to pose — and perhaps answer — critical questions about the fragility and resilience of life on Earth.

Since the massacre that took the lives of 19 schoolchildren in Uvalde, Texas, people across the world began to ask versions of one question: why did police wait outside the door instead of protecting the kids? It's not the first time this question has come up. Two years ago, as she watched police respond to the protests that followed the death of George Floyd, Producer B.A. Parker wondered: what are police for? With the help of our Producer Sarah Qari, she found that the United States’ Supreme Court had given this a most consequential and bewildering answer. We decided to re-air this episode to shed light on how a case from 2005 upended our assumptions about the role police are meant to play in our lives.

A few months ago, co-Host Latif Nasser, who was otherwise healthy, saw blood in his poop. It was the start of a medical journey that made him not only question what was going on in his body, but also dig into the secret genetic story of how we became human. Curled up in a hospital bathroom, Latif tries to sort out whether his ordeal is the result of a long-lost sibling knifing him in the gut or, on the contrary, a long-forgotten kindness shared between two human-ish travelers.  Special thanks to Azra Premiji, Avir Mitra, Suzanne Lehrer, David Reich, Sriram Sankararaman, Ainara Sistiaga, Carl Zimmer, Carly Mensch, Nihal Kaur, Charlotte Hsu and Bert Gambini at the University at Buffalo Media Relations, and Latif's GI Doctor Florence Damilola Odufalu and her entire team, as well as all the staff at LA County-USC Medical Center and Keck USC hospitals who looked after Latif during his hospitalization.

We’re all in a tizzy here at Radiolab on account of our 20-year anniversary. And, as one does upon passing a milestone, we’ve been looking back in all kinds of ways. Two weeks ago, we went out over the airwaves, “Live on your FM dial,” a callback to our origins as a radio show. We revamped our logo and redid our website (get your Freq on, people!). More recently, Lulu's and Latif’s first stories came up in a meeting. They weren’t always the intrepid hosts of our collective journey in wonder. Soren Wheeler, our editor, thought it would be fun to highlight those firsts for you.  So here they are, baby Latif and Lulu, doing their darndest to make audio magic.

Back in 2002, Jad Abumrad started Radiolab as a live radio show. He DJ’d out into the ether and 20 years later we do the same. To commemorate the 20-year anniversary of the show, the Radiolab team went old school and took over WNYC Radio, live on the FM band. We answered the phones, played some wonderfully weird audio, including one piece where Kurt Vonnegut—yes, that Kurt Vonnegut—interviews the dead, took part in some games and tomfoolery, and did everything we could to have and to share in our good time.

All the world’s a stage. Or, sometimes it feels that way, especially these days. In this episode, originally aired in 2015, we push through the fourth wall, pierce the spandex-ed heart of professional wrestling, and travel 400 years into the past to unmask our obsession with authenticity and our desire to walk the line between reality and fantasy.

This week, we bring you two stories about little guys trying to do big big things. First, self-proclaimed animal grinch producer Becca Bressler introduces us to perhaps the one creature that has warmed her heart: a cricket. And more specifically, a male cricket. This is a tale about a tiny Romeo insect trying to find a mate, and the ingenious lengths he’ll go to have his beckoning heard. The hero of our story   And second, producer Annie McEwen journeys through perhaps the zaniest game of football that has ever been played. When a ragtag group of players take on the top team, will it be an underdog tale for the ages or an absolute disaster? Special thanks to Stephen Spann and Joshua Baxter at the Doris and Harry Vice University Library at Cumberland University as well as Alison Reynolds at Georgia Tech Library. Thanks also to Rick Bell, and to Scott Larson who wrote a book all about this game called Cumberland: The True Story of the Highest Scoring Football Game in History. And finally, thanks so much to our

In competitive debate future presidents, supreme court justices, and titans of industry pummel each other with logic and rhetoric.  Unclasp your briefcase. It’s time for a showdown. Looking back on an episode originally aired in 2016, we take a good long look at the world of competitive college debate. This is Ryan Wash's story. He's a queer, Black, first-generation college student from Kansas City, Missouri who joined the debate team at Emporia State University on a whim. When he started going up against fast-talking, well-funded, “name-brand” teams, from places like Northwestern and Harvard, it was clear he wasn’t in Kansas anymore. So Ryan became the vanguard of a movement that made everything about debate debatable. In the end, he made himself a home in a strange and hostile land. Whether he was able to change what counts as rigorous academic argument … well, that’s still up for debate. Special thanks to Will Baker, Myra Milam, John Dellamore, Sam Mauer, Tiffany Dillard Knox, Mary Mudd, Darren "Chief" Ell

As a species, we’re obsessed with names. They’re one of the first labels we get as kids. We name and rename absolutely everything around us. And these names carry our histories, they can open and close our eyes to the world around us, and they drag the weight of expectation and even irony along with them. This week on Radiolab, we’ve got six stories all about names. Horse names, the names of diseases, names for the beginning, and names for the end. Listen to “Hello, My Name Is” on Radiolab, wherever you find podcasts.  Special thanks to Jim Wright, author of “The Real James Bond”, Tad Davis, Cole delCharco, Peter Frick-Wright, Alexa Rose Miller, Katherine De La Cruz, and Fahima Haque.Members of The Lab, watch for an audio extra on your exclusive feeds, a poem written and read by Mary Szybist, whom Molly Webster interviewed for her story in this episode about endlings.

Almost exactly twenty years ago, detainee 244 got transferred to Guantanamo Bay. Captured by American forces at the battle Tora Bora five months previous, Abdul Latif Nasser was shaved, hooded, shackled, diapered, and flown halfway across the world. The Radiolab special series, The Other Latif, kicked off when one of our hosts, Latif Nasser, made a bizarre and shocking discovery. He shares his name with detainee 244. A man the U.S. government paints a terrifying picture of as Al-Qaeda’s top explosives expert, and one of the most important advisors to Osama bin Laden. Nasser’s lawyer claims, on the other hand, that he was at the wrong place at the wrong time, and that he was never even in Al-Qaeda. This clash launched our Latif into a years-long investigation, picking apart evidence, attempting to separate fact from fiction, and trying to uncover what the man with whom he shares a name actually did or didn’t do. Along the way, Radiolab’s Latif reflects on American values and his own religious past, and wonders

A one-word magical spell. Several years back, that’s exactly what Joseph Tartaro thought he’d discovered. It was a spell that, if used properly, promised to make one’s problems disappear. And so he crossed his fingers, uttered the word and cast the enchantment on himself. The result, however, was anything but magical. Unbeknownst to Joseph, by unleashing this spell, he’d earned a lifetime membership into a cursed community. A clan made up of folks who, through no fault of their own, had become nameless and invisible. Today, the story of these unfortunate souls, the dark digital arts that took so much from them and the wizardry needed to give them new life. Special thanks to Sarah Chasins, Tony Hoare, Brian Kernighan and to Patrick McKenzie for writing that wonderful list of assumptions programmers believe about names. And also to all the folks who spoke to us and emailed us with stories of their own ‘problematic’ names. DOWNLOAD BRAILLE READY FILE HERE Support Radiolab by becoming a member of The Lab today.  

Horror, fashion, and the end of the world … In this episode, first aired in 2014, but maybe even more relevant today, things get weird as we explore the undercurrents of thought that link nihilists, beard-stroking philosophers, Jay-Z, and True Detective. Today on Radiolab, a puzzle. Jad’s brother-in-law wrote a book called 'In The Dust of This Planet'. It’s an academic treatise about the horror humanity feels as we realize that we are nothing but a speck in the universe. For a few years nobody read it. But then … It seemed to show up on True Detective.   Then in a fashion magazine.   And then on Jay-Z's back. How?  We talk nihilism with Eugene Thacker & Simon Critchley, leather jackets with June Ambrose, climate change with David Victor, and hope with the father of Transcendental Black Metal - Hunter Hunt Hendrix of the band Liturgy. Also, check out WNYC Studio's On the Media episode Staring into the Abyss, in it Brooke Gladstone and Jad Abumrad continue their discussion of nihilism and its place in hist

Once a kid is born, their genetic fate is pretty much sealed. Or is it? In this episode, originally aired in 2012, we put nature and nurture on a collision course and discover how outside forces can find a way inside us, and change not just our hearts and minds, but the basic biological blueprint that we pass on to future generations.Support Radiolab by becoming a member of The Lab today.     Radiolab is on YouTube! Catch up with new episodes and hear classics from our archive.

Since the beginning of the space program, we’ve always expected astronauts to be fully abled athletic overachievers who are one-part science-geek, two-parts triathlete – a mix the writer Tom Wolfe famously called “the right stuff.” But what if, this whole time, we’ve had it all wrong? In this episode, reporter Andrew Leland joins a blind linguistics professor named Sheri Wells-Jensen and a crew of eleven other disabled people on a mission to prove that disabled people have what it takes to go to space. And not only that, but that they may have an edge over non-disabled people. We follow the Mission AstroAccess crew members to Long Beach, California, where they hop on an airplane to take an electrifying flight that simulates zero-gravity – a method used by NASA to train astronauts – and afterwards learn that the biggest challenges to a future where space is accessible to all people may not be where they expected to find them. And our reporter Andrew, who is legally blind himself, confronts some unexpected conc

Stress can give your body a boost - raising adrenaline levels, pumping blood to the muscles, heightening our senses. And those sudden superpowers can be a boon when you’re running from a lion. But repeatedly dipping into that well can make you sick, even kill you. Since it feels like there’s been an extra bit of stress going around lately, we decided to replay this episode, originally aired back in 2005, which takes a long hard look at the body's system for getting out of trouble. And how in our modern, hyper-connected world, that system misfires and takes us from the frying pan, right into another, albeit entirely different, frying pan. Stanford University neurologist (and part-time "baboonologist") Dr. Robert Sapolsky takes us through what happens on our insides when we stand in the wrong line at the supermarket, and offers a few coping strategies: gnawing on wood, beating the crap out of somebody, and having friends. Plus: the story of a singer who lost her voice, and an author stuck in a body that never g

Fantasy writer Elsa Sjunneson has been haunted by Helen Keller for nearly her entire life. Like Helen, Elsa is Deafblind, and growing up she was constantly compared to her. But for a million different reasons she hated that, because she felt different from her in a million different ways. Then, a year ago, an online conspiracy theory claiming Helen was a fraud exploded on TikTok, and suddenly Elsa found herself drawing her sword and jumping to Helen’s defense, setting off a chain of events that would bring her closer to the disability icon than she ever dreamt. For over a year, Elsa, Lulu and the Radiolab team dug through primary sources, talked to experts, even visited Helen’s birthplace Ivy Green, and discovered the real story of Helen Keller is far more complicated, mysterious and confounding than the simple myth of a young Deafblind girl rescued by her teacher Annie Sullivan. It’s a story of ghosts, surprises, a few tears, a bit of romance, some hard conversations, and a possibly psychic dog.This episode

This week, 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). This episode was reported by Latif Nasser, Matt Kielty, Heather Radke, Lulu Miller and Candice Wang. It was produced by Matt Kielty and Simon Adler. Sound and music from Matt Kielty, Simon Adler, and Jeremy Bloom, and dialogue mix by Arianne Wack.Special thanks to Alan and Alida Goffinski for giving our chaos musical life in the

We live our lives at human speed, we experience and interact with the world on a human time scale. In this episode, which first aired in its entirety in the winter of 2013, we put ourselves through the paces. We examine a material that exists between two states of matter, take a ride on the death-defying roller coaster that is the stock market, open up our internal clocks of thought, and achieve mastery over the fastest thing in the universe.
