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. 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 tape syncer Ambriehl Crutchfield for her help with this episode.  If you’re still interested in learning more about this epic football game, be sure to check out this brilliant and hilarious video by sportswriter Jon Bois. Lastly, don't forget to check out Death Sex and Money. We recommend episode titled Hard, which is deep dive into our relationship with erectile dysfunction, and the drugs developed to treat it.   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.

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.

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 how a fellow nerdy, suburban Muslim kid, may have gone down such a strikingly different path. Episode 5: Cuba-ish  To mark the solemn occasion of the other Latif's transfer to, "the legal equivalent of outer space," we thought we'd replay Cuba-ish, the fifth episode of our special series which first aired back in 2020. In this episode, our Latif heads to Guantanamo Bay to try to speak to his namesake. Before he gets there, he dives deep, seeking the answer to what seems like a simple question: why Cuba? Why in the world did the United States pick this sleepy military base in the Caribbean to house “the worst of the worst”?  Support Radiolab by becoming a member of The Lab today.     Radiolab is on YouTube!

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.

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 history.

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 conclusions of his own.This episode was reported by Andrew Leland and produced by Maria Paz Gutierrez, Matt Kielty and Pat Walters.

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 grew up.

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 was reported by Elsa Sjunneson and Lulu Miller. It was produced by Sindhu Gnanasambandan and Rachel Cusick, with help from Sarah Qari, Tanya Chawla, and Carolyn McClusker. Jeremy Bloom contributed music and sound design.

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.

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.

This week, we turn to an expert who tromps the wilds of wordlessness. Lulu’s young son. In this essay, originally published for The Paris Review under the title “The Eleventh Word,” Lulu explores what is lost with the gaining of language. And how, in a very odd way, a fear of confusion and the unknown may begin with the advent of words. The Radiolab sound team brings this piece to life with original music, and at one point the words melt right out of the air. Support Radiolab by becoming a member of The Lab today.

It's hard to start a conversation with a stranger—especially when that stranger is, well, different. He doesn't share your customs, celebrate your holidays, watch your TV shows, or even speak your language. Plus he has a blowhole. In this episode, which originally aired in the summer of 2014, we try to make contact with some of the strangest strangers on our little planet: dolphins. Producer Lynn Levy eavesdrops on some human-dolphin conversations, from a studio apartment in the Virgin Islands to a research vessel in the Bermuda Triangle.

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 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. This episode is a layer cake of arboreal surprises (including the reappearance of a certain retired host).  A few visual tre(e)ats:  We first learned about the magical world of the canopy from this beautiful video from Michael Werner, Joe Hanson, and the PBS Overview team. It features Korena Mafune’s research up in the treetops, as well as the people who have dedicated their lives to saving what’s left of the old growth forests. We highly recommend checking it out! And, if you’re hankering to go climb a tree after this episode, you might enjoy browsing Hallie Bateman’s wonderfully illustrated guide to the best climbing trees in NYC for a little inspiration.Support Radiolab by becoming a member today at Radiolab.org/donate.Radiolab is on YouTube!

Jad started Radiolab roughly 20 years ago. And now he is stepping aside from hosting and producing the show to replenish, to think, to rock in his chair and be with his kids and wife, and maybe make some music. The news has been all over twitter and there’s a letter from Jad and our hosts Latif and Lulu on the website. But in this episode, Jad talks through his decision to leave and the future of the show with Lulu and Latif. And then, as a parting gift, we play him the very first episode of Radiolab (“The Radio Lab” as he called it then). He tells us about biking the CDs over the Brooklyn bridge just before the show was supposed to air, reading the news and weather between segments, and then we just sit back together and listen to where it all began. Jad, for those of us who have been radically changed by the thing you put out into the world, we are both sad to lose you in our ears and endlessly grateful for what you’ve given us.

Last week, Lulu heard an interview that trapped her in her car. She decided to play it for Latif. The interview – originally from a podcast called The Relentless Picnic, but presented by one of Lulu’s current podcast faves, The 11th – is part of an episode of mini pep talks designed to help us all get through this cold, dark, second-pandemic-winter-in-a-row. But the segment that Lulu brings Latif is about someone trying to get through something arguably much more difficult, something a pep talk can’t solve, but that a couple friends — and one very generous stranger — might be able to help make a little more bearable. The episode of The 11th this comes from is “I’m Here to Pep You Up.” The Relentless Picnic is currently running a series of episodes called CABIN, an audio exploration of isolation, which you can listen to here. The organization where Matt volunteers as a counselor is called SUDEP. The Lu Olkowski story Lulu recommends at the end of the episode is “Grandpa,” and the lobster story Latif recommends is “The Luckiest Lobster.” Special Thanks: Eric Mennel, senior producer at The 11th, and host of the podcast Stay Away from Matthew Magill.Lu Olkowski, voracious listener, super reporter, and host of the podcast Love Me.Radiolab is on YouTube!

It would seem that hackers today can do just about anything they want - from turning on the cellphone in your pocket to holding your life's work hostage. Cyber criminals today have more sophisticated tools, have learned to work collaboratively around the world and have found innovative ways to remain deep undercover in the internet's shadows. This episode, we shine a light into those shadows to see the world from the perspectives of both cybercrime victims and perpetrators. First we meet mother-daughter duo Alina and Inna Simone, who tell us about being held hostage by criminals who have burrowed into their lives from half a world away. Along the way we learn about the legally sticky spot that unwitting accomplices like Will Wheeler find themselves in. Then reporter and author Joseph Menn tells us about the surprisingly lucrative professional hacker structure in places throughout the former Soviet Union. Finally, the co-creator of one of the most notorious online marketplaces to ever exist speaks to us and NPR cyber-crime expert Dina Temple-Raston about how a young suburban Boy Scout can turn into a world renowned black hat hacker.

What was the worst year to be alive on planet Earth?   We make the case for 536 AD, which set off a cascade of catastrophes that is almost too horrible to imagine. A supervolcano. The disappearance of shadows. A failure of bread. Plague rats. Using evidence painstakingly gathered around the world - from Mongolian tree rings to Greenlandic ice cores to Mayan artifacts - we paint a portrait of what scientists and historians think went wrong, and what we think it felt like to be there in real time. (Spoiler: not so hot.)  We hear a hymn for the dead from the ancient kingdom of Axum, the closest we can get to the sound of grief from a millennium and a half ago. The horrors of 536 make us wonder about the parallels and perpendiculars with our own time: does it make you feel any better knowing that your suffering is part of a global crisis? Or does it just make things worse?"Thanks to reporter Ann Gibbons whose Science article "Eruption made 536 ‘the worst year to be alive" got us interested in the first place. In case you want to learn more about 536, here are some other sources: Timothy P.
