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 st...

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. Special thanks to Grace Gilbert for voice acting and episode art, and to Professors Erin Anderson and Maggie Jones for edito...

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 l...

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...

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 Pri...

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. Special tha...

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 vaccin...

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 scien...

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...

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 a...

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, o...

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...

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...

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 spandexed 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. Thanks to Nick Hakim for the use of  his song "The...

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 her...

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 Cit...

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 disea...

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 n...

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 membersh...

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 h...

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.    ...

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 e...

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 i...

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...

This week, we flip the Disney story of life on its head thanks to a barrel of seawater, a 1970's-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...
