Radiolab Podcasts (Radiolab)

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 m...

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 orig...

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...

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...

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...

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...

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 se...

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...

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 ben...

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...

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 w...

In tape five, three stories: first, a tale of how the cassette tape supercharged the self-help industry. Second, cassettes filled with history make an epic journey across Africa with a group of Lost Boys. And finally, Simon meets up with fellow Radiolabber David Gebel to dig through an old box of mixtapes and rediscover the unique power of these bygone love letters. Mixtape was reported, produced,...

In 1983, Simon Goodwin had a strange thought: Would it be possible to broadcast computer software over the radio? If so, could listeners record it off the air and onto a cassette tape? This experiment and dozens of others in the early 80s created a series of cassette fueled, analog internets. They copied and moved information like never before, upended power structures and created a poisonous soci...

As the Vietnam war dragged on, the US military began desperately searching for any vulnerability in their North Vietnamese enemy. In 1964, they found it. It was an old Vietnamese folktale involving a ghost, eternal damnation and fear - a tailor made weaponizable myth. And so, armed with tape recorders and microphones, the military set out to win the war by bringing this ghost story to life. Today,...

In 1946 Bing Crosby was the king of media. He was the movie star, the pop star and his radio show was reaching a third of American living rooms each week.  But then, it all started to fall apart. His ratings were plummeting and his fans were fleeing. Bing however, was not going down without a fight.  Today, the story of how Bing Crosby and some stolen Nazi technology won his audience back, changed...

Through the 1980s, the vast majority of people in China had never heard Western music, save for John Denver, the Carpenters, and a few other artists included on the hand-picked list of songs sanctioned by the Communist Party. But in the late '90s, a mysterious man named Professor Ye made a discovery at a plastic recycling center in Heping. In episode 1 of Mixtape, we talk to Chinese historians, mu...

Ecologist Nick Haddad was sitting in his new office at North Carolina State University when the phone rang. On the other end of the line was... The U.S. Army. The Army folks told him, “Look, there’s this endangered butterfly on our base at Fort Bragg, and it’s the only place in the world that it exists. But it’s about to go extinct. And we need your help to save it.”  Nick had never even heard of...

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. But 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 pe...

Today we have a story about the sometimes obvious but sometimes sneaky effects of the way that we humans rearrange the elemental stuff around us. Reporter Avir Mitra and science journalist Lydia Denworth bring us a story about how one man’s relentless pursuit of a deep truth about the Earth led to an obsession that really changed the very air we breathe. This episode was reported by Avir Mitra, an...

Diane Van Deren is one of the best ultra-runners in the world, and it all started with a seizure. In this short, Diane tells us how her disability gave rise to an extraordinary ability. For Van Deren, a charming mother of three, daily life is a struggle. But as soon as she steps outdoors, she's capable of amazing feats. She can run for days on end with no sleep, covering hundreds of miles in extre...

It has now been 20 years since September 11th, 2001. So we’re bringing you a Peabody Award-winning story from our archives about one sentence, written in the hours after the attacks, that has led to the longest war in U.S. history. We examine how just 60 words of legal language have blurred the line between war and peace. In the hours after the attacks of Sept. 11, 2001, a lawyer sat down in front...

Multiple sclerosis, lupus, rheumatoid arthritis, even psoriasis—these are diseases in which the body begins to attack itself, and they all have one thing in common: they affect women more than men. Most autoimmune disorders do. And not just by a little bit, often by a lot; in some cases, as much as sixteen times more. But why? On today’s episode, we talk to scientists trying to answer that questio...

We all think we know the story of pregnancy. Sperm meets egg, f ollowed by nine months of nurturing, nesting, and quiet incubation . But this story isn’t the nursery rhyme we think it is. In a way, it’s a struggle, almost like a tiny war. And right on the front lines of that battle is another major player on the stage of pregnancy that not a single person on the planet would be here without. An en...

In 2014, India’s Dutee Chand was a rising female track and field star, crushing national records. But then, that summer, something unexpected happened: she failed a gender test. And was banned from the sport. Before she knew it, Dutee was thrown into the middle of a controversy that started long before her, and continues on today: how to separate males and females in sport. First aired in 2018, Du...

If you’ve ever lost someone, or watched a medical drama in the last 15 years, you’ve probably heard of The Five Stages of Grief. They’re sort of the world’s worst consolation prize for loss. But last year, we began wondering… Where did these stages come from in the first place? Turns out, Elisabeth Kübler-Ross. But the story is much, much more complicated than that. T hose stages of grieving? They...
