Radiolab

A mile under the ocean, we get to watch an octopus perform a heroic act of heart and determination.

What if the smell of death is actually the smell of life?

Machines are answering our hardest problems... Does it matter if we don’t understand how?

A neurologist issues a dare to a ragtime piano player and a famous conductor, then the impossible happens.

A tiny ode to grass, for its epic role in human history.

What is the sweetest thing in the world?

A tiny baby, born at 23 Weeks and 6 days—roughly halfway to full term. And a whole universe of medical and moral questions.

It’s been 25 years since 9/11. Today we talk about the 60 words that ushered in everything that came after.

We will always love you, Dolly.

The greatest mysteries have a shadowy figure at the center, Patient Zero. We hunt for Patient Zeroes from all over the map.

A love story about a rogue bird and his concrete lover.

A deep-sea Cold War mystery with subs and bombs and science.

The world around you is falling apart, and no one is listening. How far do you go to be heard?

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.

Whether it comes from government spokespeople or celebrity publicists, the phrase “can neither confirm nor deny” is the perfect non-denial denial.

What your body knows that your brain doesn’t … yet.

America represents many different things to many different people. What if you could only choose one thing, one physical object, to represent it all?

What happens when doing what you love means giving up who you really are?

We don’t have hormones, hormones have us.

Father nature.

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.

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.

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 NeasonProduced by - Jessica Yung and Annie McEwenwith mixing help from - Jeremy BloomFact-checking by - Sophie Samieeand 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 Other cool stuff - Have fun with neuroscience and ...

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?

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. This episode is a layer cake of arboreal surprises (including the reappearance of a certain retired host.

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.

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.

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 MitraProduced by - Jessica YungSound design contributed by - Jeremy Bloom and Jessica YungFact-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?

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. Collins, Max Scott, Amy Murillo, Daniel Griffin, Phil Kaufman, Katie Barnhill, Arthur Caplan, Ron Sandler, Yasha Rohwer, Aaron Keefe, Gwendolyn Bogard, Maria Sabate, Meredith Asbury, and Joanne Padrón Carney

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.

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 Abumradwith 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. The Honeybee Algorithm won a Golden Goose Award back in 2016 (https://www.goldengooseaward.org/01awardees/honey-bee-algorithm).

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.

One spring evening in 2024, a science journalist named Rachel Gross bombed at karaoke. The culprit was a bleed in a fist-sized clump of neurons tucked down in the back of her brain called the cerebellum. A couple weeks later, her doctors took a bit of it out, assuring her it was just helping her with motor coordination — she might be a bit clumsy for a while, but she’d still be herself. But afterwards, she didn't feel like herself. So she dove into the dusty basement of the brain (and brain science) to figure out why. What Rachel found was a burgeoning new frontier in neuroscience. We learn what singing Shakira on stage has to do with reaching for a cup of coffee — and how the surprising relationship between the two is making us rethink what we think about thinking. Special thanks to Warzone Karaoke at Branded Saloon, Dr. Joanne Loewy and the Singing Together, Measure by Measure choir at the Louis Armstrong Center for Music and Medicine (http://musicandmedicine.org/) at Mount Sinai Union Square, Dag Spicer and the Computer History Museum, Désirée Lie, Mark Gross, 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?

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.

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?

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.

After 35, does fertility tank? 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 live event was produced by Rachael Cusick and edited by Pat Walters. Special thanks to epidemiologist Lauren Wise, at Boston University. Plus, Emily, Chloe, and Bianca.

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 Gnanasambandan Sign up for our newsletter!!

In the weeks following the full-scale invasion of Ukraine, a young doctor in Germany sees that abortion pills are urgently needed in Ukraine. And she wants to help. But getting the drugs into the country means going through Poland, which has some of the strictest abortion laws in Europe. So, she gets creative. What unfolds is a high-stakes, covert-operation run by a group of strangers. With everyone deciding: who to trust?

In this episode, first aired in 2011, we talk about the meaning of a good game — whether it's a pro football playoff, or a family showdown on the kitchen table. And how some games can make you feel, at least for a little while, like your whole life hangs in the balance. This hour of Radiolab, Jad and Robert wonder why we get so invested in something so trivial. What is it about games that make them feel so pivotal? We hear how a recurring dream about football turned into a real-life lesson for Stephen Dubner, we watch a chessboard turn into a playground where by-the-book moves give way to totally unpredictable possibilities, and we talk to Dan Engber, a one time senior editor at Slate, now at The Atlantic, and a bunch of scientists about why betting on a longshot is so much fun. And finally, we talk to Malcolm Gladwell about why he loves the overdog. CITATIONS: Videos -  The Immaculate Reception (https://zpr.io/izhV3Sm88SWF) by Franco Harris on December 23, 1972.

This episode —first released in 2009 and then again in 2015, with an update — asks, what is “normal”? Maybe it exists, maybe not. We examine peace-loving baboons with Stanford neuroscientist Robert Sapolsky, talk to Stu Rasmussen, whose preferred pronouns were he/him (https://zpr.io/nUdsZawNmhwt), and his neighbors in Silverton, Oregon about how a town chooses its community over outsider opinions. And lastly, we speak with an evolutionary anthropologist, Duke University’s own Brian Hare, and an evolutionary biologist Tecumseh Fitch, then at the University of St. Andrews, Scotland, now at the University of Vienna, Austria, about foxes who love to snuggle.And what we find is that normal — maybe the only normal — is change.

This episode, first aired in 2017, has Reporter Tracie Hunte and Editor Soren Wheeler exploring a hidden power in the U.S. Court System that is either the cornerstone of our democracy or a trapdoor to anarchy. Should a juror be able to ignore the law? From a Quaker prayer meeting in the streets of London to riots in the streets of Los Angeles, we trace the history of a quiet act of rebellion and struggle with how much power “We the People” should really have.Special thanks to Darryl K.

After graduating from high school, without a clear plan for what to do next, Laura Andrews started asking herself a lot of questions. A spiral of big philosophical thoughts that led her to sit down and write to us with a question that was… oddly mathematical.  What is the most average size thing, if you take into account everything in the universe. So, along with mathematician Steven Strogatz, we decided to see if we could sit down and, in a friendly throwdown of guesstimates and quick calculations, rough out an answer.  Special thanks to all the listeners who sent in their responses to this question.

A global pandemic. Thousands dying. A passive government. An afflicted group fueled by grief and anger. In this episode, first aired in 2020, Reporter Tracie Hunte wanted to understand this moment of pain and confusion. As she looked back three decades, she found a complicated answer to a simple question: when nothing seems to work, how do you make change? Special thanks to Dr. Anthony Fauci.

When U.S. Supreme Court Chief Justice Earl Warren was asked at the end of his career, “What was the most important case of your tenure?”, there were a lot of answers he could have given. He had presided over some of the most important decisions in the court’s history — cases that dealt with segregation in schools, the right to an attorney, the right to remain silent, just to name a few. But his answer was a surprise: he said “Baker v. Carr,” a 1962 redistricting case.  On this 2016 episode, part of our series More Perfect, we talk about why this case was so important. Important enough that it pushed one Supreme Court justice to a nervous breakdown, brought a boiling feud to a head, gave another justice a stroke, and changed the course of the Supreme Court — and the nation — forever.This episode is the one of the few times you can hear the voice of our Executive Producer Suzie Lechtenberg. After years of leading the team, Suzie will leave WNYC to start her new adventure. Suzie: re-publishing this episode is our way of saying thank you for all you’ve done — for the show and for each of us.

Mel Blanc was known as “the man of 1,000 voices,” but, to hear his son tell it, the actual number was closer to 1,500. Bugs Bunny, Porky Pig, Daffy Duck, Tweety, Barney Rubble, Woody Woodpecker, Sylvester, Foghorn Leghorn — all Mel. These characters made him one of the most beloved men in the United States. In this episode from 2012, Mel Blanc’s son Noel tells Producer Sean Cole how his father’s entire body would transform to bring life to these characters. But on a fateful day of 1961, after a crash left Mel in a lengthy coma, it was the characters who brought life to him.Episode Credits:Reported by Sean Cole Our newsletter comes out every Wednesday.

Why do we have a butt? Well, it’s not just for the convenience of a portable seat cushion. This week, we have a conversation with our Contributing Editor Heather Radke, who has spent the last several years going deep on one of our most noticeable surface features. She’s been working on a book called Butts, a Backstory and in this episode, she tells us about a fascinating history she uncovered that takes us from a eugenicist’s attempt in the late 1930s to concretize the most average human, to the rise of the garment industry, and the pain and shame we often feel today when we go looking for a pair of pants that actually fit.

This hour, we dive into the messy mystery in the middle of us. What's going on down there? And what can the rumblings deep in our bellies tell us about ourselves?  We join author Mary Roach and reach inside a live cow's stomach. Talk with writer Frederick Kaufman about our first peek into the wonderful world of human digestion that came about thanks to a hunting accident. And explore with show regular, science writer, and fellow water drinker, Carl Zimmer, about the trillions of microscopic creatures that keep us regulated, physically, but also, maybe, emotionally and spiritually.

Meteorologists are as common as the clouds these days. Rolling onto the airwaves at morning, noon and night they tell us what to wear and where to plan our picnics. They’re local celebrities with an outsized influence. But in the 1940s, there was really only one of them: Irving P. Krick. He was suave and dapper, with the charm of a sunbeam and the boldness of a thunderclap. He was a salesman who turned the weather into a product. Today, listen to the story of Krick and his descendants, a crew of profit prophets who have found fame and fortune staring at the sky and seeing the future. We follow them from the bloody beaches of World War II to the climate changed coasts of today, exploring their impact and predicting what they’ll mean in our wackier weather world.  Special Thanks:Special thanks to Xandra Clark, Homa Sarabi, Santi Dharmawan, Francisco Alvarez, Maureen O’Leary and everyone at NOAA, Shimon Elkabetz, Jack Neff, Joe Pennington, Brad Colman, Morgan Yarker, Megan Walker, Eric Bramford, Jay Cohen and Irving Krick Jr for supplying us with tons of great archival footage and audio.  Episode Credits: Reported by Simon Adler and Annie McEwenProduced by Annie McEwen and Simon AdlerSound & Music by Simon Adler and Annie McEwen and Jeremy BloomMixing help from Arianne WackFact-checking by Diane KellyEdited by Soren Wheeler Citations: Books:  If you’re curious to know more about the history of weather forecasting, go check out Kris Harper’s book Weather by the Numbers.

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 that in-between space. 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.

When the Dobbs decision went down, ER doctor Avir Mitra started to prepare for the worst — botched, at-home abortions that would land pregnant people in the emergency room. To prepare himself and his colleagues for the patients they might see, and to think through how best to treat them, Avir asked Laura MacIsaac, one of New York City’s leading gynecologists and abortion experts, to come talk to his ER department. But what Dr. MacIsaac had to say in her lecture wasn’t what Avir expected: she didn’t talk about how we’re going back in time and the horrors of self-harm as a means to an abortion. Instead, she painted a picture of progress — how in the last 40 years, through private practice and clinical trials all around the world, the process and science of providing and having an abortion has changed dramatically, mostly because of two types of pills: misoprostol and mifepristone. On this episode, Avir and Senior Correspondent Molly Webster visit Dr. MacIsaac to hear more, and also learn about a new study that indicates the process of abortion is on the precipice of even further change.  Special thanks to Mariana Prandini Assis and Pam Belluck.

It all started when the rockstar David Byrne did a Freaky-Friday-like body-swap with a Barbie Doll. That’s what inspired him — along with his collaborator Mala Gaonkar — to transform a 15,000 square-foot warehouse in Denver, Colorado into a brainy funhouse known as the Theater of the Mind. This episode, co-Host Latif Nasser moderates a live conversation between Byrne and Neuroscientist Thalia Wheatley at the Denver Center for the Performing Arts. The trio talk about how we don’t see what we think we see, don’t hear what we think we hear, and don’t know what we think we know, but also how all that… might actually be a good thing.

When people are dying and you can only save some, how do you choose? Maybe you save the youngest. Or the sickest. Maybe you even just put all the names in a hat and pick at random. Would your answer change if a sick person was right in front of you? In this episode, first aired back in 2016, we follow New York Times reporter Sheri Fink as she searches for the answer. In a warzone, a hurricane, a church basement, and an earthquake, the question remains the same. What happens, what should happen, when humans are forced to play God?

Lulu Miller, intrepid host and fearless mother of two, went off on her own and put together a little something for kids. All kids: hers, yours, and the one still living inside us all.  Radiolab for Kids Presents: Terrestrials And it’s spellbinding. So much so, that we wanted to put this audio goodness in front of as many ears as possible.  Which is why we’re running the first episode of that series here for you today.  It’s called The Mastermind. In it, Sy Montgomery, an author and naturalist, shares the story of a color-changing creature many people assumed to be brainless who outsmarts his human captors. If you want a SPOILER of what the creature is, read on: It’s an octopus. We hear the story of one particularly devious octopus who lost a limb, was captured by humans, and then managed to make an escape from its aquarium tank—back into the ocean! The tale of “Inky” the octopus calls into question who we think of as intelligent (and kissable) in the animal kingdom.

For many of us, quicksand was once a real fear — it held a vise grip on our imaginations, from childish sandbox games to grown-up anxieties about venturing into unknown lands. But these days, quicksand can't even scare an 8-year-old. In this short, we try to find out why.  Then-Producer Soren Wheeler introduces us to Dan Engber, writer and columnist for Slate, now with The Atlantic. Dan became obsessed with quicksand after happening upon a strange fact: kids are no longer afraid of it. In this episode, Dan recounts for Soren and Robert Krulwich the story of his obsession. He immersed himself in research, compiled mountains of data, met with quicksand fetishists and, in the end, formulated a theory about why the terror of his childhood seems to have lost its menacing allure. Then Carlton Cuse, who at the time we first aired this episode was best-known as the writer and executive producer of Lost, helps us think about whether giant pits of hero-swallowing mud might one day creep back into the spotlight.And, as this episode first aired in 2013, we can see if we were right.   Episode Credits:Reported and produced by Soren Wheeler Our newsletter comes out every Wednesday.

In the fall of 2004, Jeanna Giese checked into the Children's Hospital of Wisconsin with a set of puzzling symptoms... and her condition was deteriorating fast. By the time Dr. Rodney Willoughby saw her, he only knew one thing for sure: if Jeanna's disturbing breakdown turned out to be rabies, she was doomed to die. What happened next seemed like a medical impossibility. In this episode, originally aired in 2013, Producer Tim Howard tells Jeanna's story and talks to authors Monica Murphy and Bill Wasik, and scientists Amy Gilbert and Sergio Recuenco, while trying to unravel the mystery of an unusual patient and the doctor who dared to take on certain death.

Learn a new language faster than ever! Leave doubt in the dust! Be a better sniper! Could you do all that and more with just a zap to the noggin? Maybe. Back in the early 2010s, Sally Adee, then an editor at New Scientist Magazine, went to a DARPA (Defense Advanced Research Projects Agency) conference and heard about a way to speed up learning with something called trans-cranial direct current stimulation (tDCS). A couple of years later, Sally found herself wielding an M4 assault rifle to pick off simulated enemy combatants with a battery wired to her temple. But that got then-producer Soren Wheeler thinking about this burgeoning world of electroceuticals, and if real, what limits will it reach. For this episode, first aired back in 2014, we brought in Michael Weisend, then a neuroscientist at Wright State Research Institute, to tell us how it works (Bonus: you get to hear Jad get his brain zapped). And sat down with Peter Reiner and Nick Fitz, then at the University of British Columbia, to help us think through the consequences of a world where anyone with 20 dollars and access to a circuit board and a soldering iron, can make their own brain zapper. And then checked-in again to hear about the unexpected after-effects a day of super-charged sniper training can have on one mild-mannered science journalist.

In August 2018, Boen Wang was at a work retreat for a new job. Surrounded by mosquitoes and swampland in a tiny campsite in West Virginia, Boen’s mind underwent a sudden, dramatic transformation that would have profound consequences—for his work, his colleagues, and himself.

This episode originally aired in 2012. An all-star lineup of producers — Pat Walters, Lynn Levy, and Sean Cole — bring you stories about traps, getaways, perpetual cycles, and staggering breakthroughs.  We kick things off with a true escape artist — a man who’s broken out of jail more times than anyone alive. Why does he keep running... and will he ever stop? Next, the ingeniously simple question that led Isaac Newton to an enormous intellectual breakthrough: why doesn’t the moon fall out of the sky? In the wake of Newton's new idea, we find ourselves in a strange space at the edge of the solar system, about to cross a boundary beyond which we know nothing. Finally, we hear the story of a blind kid who freed himself from an unhappy childhood by climbing into the telephone system, and bending it to his will. Now sit back, relax and enjoy what we hope will prove to be a welcomed Escape.Episode Credits:Reported and produced by Pat Walters, Lynn Levy, and Sean Cole Leadership support for Radiolab’s science programming is provided by the Gordon and Betty Moore Foundation, Science Sandbox, a Simons Foundation Initiative, and the John Templeton Foundation.

Killer whales — orcas — eat all sorts of animals, including humpback calves. But one day, biologists saw a group of humpback whales trying to stop some killer whales from eating… a seal. And then it happened again. And again. It turns out, all across the oceans, humpback whales are swimming around stopping killer whales from hunting all kinds of animals — from seals to gray whales to sunfish. And of course while many scientists explain this behavior as the result of blind instincts that are ultimately selfish, much of the world celebrates humpbacks as superhero vigilantes of the sea. But when Annie McEwen dug into what was really going on between humpbacks and killer whales, she found a set of stories that refused to fit in either of those two ways of seeing the world.Special thanks to Eric J.

This episode, originally aired more than a decade ago, attempts to answer one question: how do you win against your worst impulses? Zelda Gamson tried for decades to stop smoking, but the part of her that wanted to quit couldn’t beat the part of her that refused to let go. Adam Davidson, a co-founder of the NPR podcast Planet Money, talked to one of the greatest negotiators of all time, Nobel Prize-winning Economist Thomas Schelling, whose tactical skills saw him through high-stakes conflicts during the Cold War but fell apart when he tried them on himself in his battle to quit smoking. And a baby Pat Walters complicates things — in a good way — with the story of two brothers, Dennis and Kai Woo, who forged a deal with each other that wound up determining both of their futures.

This week, Reporter Peter Smith and Senior Producer Matt Kielty tell the story of the U.S. Supreme Court decision that set the standard for scientific expertise in a courtroom, i.e., whether an expert can testify in a lawsuit. They also tell the story of the Daubert family — yes, the Dauberts of “Daubert v Merrell Dow” — whose win before the nine justices translated into a deeper loss.

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.

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.

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.

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.

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. 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 song at the end of the episode.

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.
