  • The Other Latif: Cuba-ish

    22/04/2022 Duration: 01h04min

    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.  

  • In the Dust of This Planet

    08/04/2022 Duration: 28min

    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

    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.

  • The Right Stuff

    25/03/2022 Duration: 41min

    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

    18/03/2022 Duration: 57min

    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

  • The Helen Keller Exorcism

    11/03/2022 Duration: 01h03min

    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

  • Life in a Barrel

    04/03/2022 Duration: 53min

    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

  • Speed

    25/02/2022 Duration: 56min

    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.

  • The Wordless Place

    18/02/2022 Duration: 26min

    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.

  • Hello

    11/02/2022 Duration: 46min

    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.

  • Forests on Forests

    04/02/2022 Duration: 24min

    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 o

  • The First Radiolab

    28/01/2022 Duration: 01h24min

    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.

  • The 11th: A Letter From George

    21/01/2022 Duration: 23min

    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

  • Darkode

    14/01/2022 Duration: 38min

    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 NP

  • Worst. Year. Ever.

    07/01/2022 Duration: 24min

    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

  • Flop Off

    31/12/2021 Duration: 01h15min

    This past year was a flop. From questionable blockbuster reboots to supply chain shenanigans to worst of all, omnipresent COVID variants. But, in a last ditch effort to flip the flop, we at Radiolab have dredged up the most mortifying, most cringeworthy, most gravity-defying flops we could find. From flops at a community pool to flops at the White House, from a flop that derails a career to flops that give NBA players a sneaky edge, from flops that’ll send you seeking medical advice to THE flopped flop that in a way enabled us all.

  • Vanishing Words

    17/12/2021 Duration: 24min

    When Alana Casanova-Burgess set out to make a podcast series about Puerto Rico, she struggled with what to call it. Until one word came to mind, a word that captures a certain essence of life in Puerto Rico, but eludes easy translation into English. We talk to Alana about her series, and that particular word, then turn to an old story about treating words as signals of something happening just beneath the surface.  Agatha Christie's clever detective novels may reveal more about the inner workings of the human mind than she intended. According to Dr. Ian Lancashire at the University of Toronto, the Queen of Crime left behind hidden clues to the real-life mysteries of human aging in her writing. Meanwhile, Dr. Kelvin Lim and Dr. Serguei Pakhomov from the University of Minnesota add to the intrigue with the story of an unexpected find in a convent archive that could someday help pinpoint very early warning signs for Alzheimer's disease and dementia. Sister Alberta Sheridan, a 94-year-old Nun Study participant, r

  • Return of Alpha Gal

    10/12/2021 Duration: 57min

    Tuck your napkin under your chin.  We’re about to serve up a tale of love, loss, and lamb chops - with a side of genetic modification. Several years ago 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 b

  • Animal Minds

    26/11/2021 Duration: 59min

    In this hour of Radiolab, stories of cross-species communication. When we gaze into the eyes of a wild animal, or even a beloved pet, can we ever really know what they might be thinking? Is it naive to assume they're experiencing something close to human emotions? Or is it ridiculous to assume that they AREN'T feeling something like that? We get the story of a rescued whale that may have found a way to say thanks, ask whether dogs feel guilt, and wonder if a successful predator may have fallen in love with a photographer.
