In this episode, first aired in 2012, we have two stories of brains pushed off-course. We relive a surreal day in the life of a young researcher hijacked by her own brain, and hear from a librarian experiencing a bizarre and mysterious set of symptoms that she called “gravitational anarchy.” Special thanks to Sarah Montague and Ellen Horn, as well as actress Hope Davis, who read Rosemary Morton’s story. And the late Berton Roueché, who wrote that story down. EPISODE CREDITS: Produced by - Brenna...
Feb 07, 2025•26 min•Transcript available on Metacast We eat apples in the summer and enjoy bananas in the winter. When we do this, we go against the natural order of life which is towards death and decay. What gives? This week, Latif Nasser spoke with Nicola Twilley, the author of Frostbite: How Refrigeration Changed Our Food, Our Planet, and Ourselves . Twilley spent over a decade reporting about how we keep food alive as it makes its way from the farm to our table. This conversation explores the science of cold, how fruits hold a secret to etern...

Jan 29, 2025•33 sec•Transcript available on Metacast In an episode first reported in 2017, we bring you a look up and down the US nuclear chain of command to find out who gets to authorize their use and who can stand in the way of Armageddon. President Richard Nixon once boasted that at any moment he could pick up a telephone and - in 20 minutes - kill 60 million people. Such is the power of the US President over the nation’s nuclear arsenal. But what if you were the military officer on the receiving end of that phone call? Could you refuse the or...
Jan 24, 2025•52 min•Transcript available on Metacast We fall down the looking glass with Sönke Johnsen, a biologist who finds himself staring at one of the darkest things on the planet. So dark, it’s almost like he’s holding a blackhole in his hands. On his quest to understand how something could possibly be that black, we enter worlds of towering microscopic forests, where gold becomes black, the deep sea meets the moon, and places that are empty suddenly become full. Corrections/Clarifications: In this episode, dragonfish are described as having...
Jan 17, 2025•26 min•Ep 622•Transcript available on Metacast In an episode we first aired in 2018, we asked the question, do you really need a brain to sense the world around you? To remember? Or even learn? Well, it depends on who you ask. Jad and Robert, they are split on this one. Today, Robert drags Jad along on a parade for the surprising feats of brainless plants. Along with a home-inspection duo, a science writer, and some enterprising scientists at Princeton University, we dig into the work of evolutionary ecologist Monica Gagliano, who turns our ...

You never know what might happen when you sign up to donate bone marrow. You might save a life… or you might be magically transported across a cultural chasm and find yourself starring in a modern adaptation of the greatest story ever told. One day, without thinking much of it, Jennell Jenney swabbed her cheek and signed up to be a donor. Across the country, Jim Munroe desper...

First, co-host Latif Nasser, with the help of Nour Raouafi, of NASA, and an edge-cutting piece of equipment, explain how we may finally be making good on Icarus’s promise. Then, co-host Lulu Miller and Ada Limón talk about how a poet laureate goes about writing an ode to one of Jupiter’s moons. And one more thing! It is almost your last chance to make your mark on the heavens. Radiolab and The International Astronomical Union...
Dec 24, 2024•26 min•Ep 619•Transcript available on Metacast The early bird gets the worm. What goes around, comes around. It’s always darkest just before dawn. We carry these little nuggets of wisdom—these adages—with us, deep in our psyche. But recently we started wondering: are they true? Like, objectively, scientifically, provably true? So we picked a few and set out to fact check them. We talked to psychologists, neuroscientists, runners, a real estate agent, skateboarders, an ornithologist, a sociologist and an astrophysicist, among others, and we l...
Dec 20, 2024•47 min•Ep 618•Transcript available on Metacast Back in 2012, when we were putting together our live show In the Dark, Jad and Robert called up Dave Wolf to ask him if he had any stories about darkness. And boy, did he. Dave told us two stories that became the finale of our show. Back in late 1997, Dave Wolf was on his first spacewalk, to perform work on the Mir (the photo to the right was taken during that mission, courtesy of NASA.). Dave wasn't alone -- with him was veteran Russian cosmonaut Anatoly Solovyev. (That's a picture of Dave givi...
Dec 13, 2024•24 min•Ep 617•Transcript available on Metacast In August of 1973, Jan-Erik Olsson walked into the lobby of a bank in central Stockholm. He fired his submachine gun at the ceiling and yelled “The party starts now!” Then he started taking hostages. For the next six days, Swedish police and international media would tie themselves in knots trying to understand what seemed to them a sordid attachment between captor and captives. And this fixation, later pathologized as “Stockholm Syndrome,” would soon spread across the globe, becoming an easy, o...
Dec 06, 2024•1 hr 5 min•Ep 616•Transcript available on Metacast In today’s story, which originally aired in 2014, we meet a very special cylinder. It's the gold standard (or, in this case, the platinum-iridium standard) for measuring mass. For decades it's been coddled and cared for and treated like a tiny king. But, as we learn from writer Andrew Marantz, things change—even things that were specifically designed to stay the same. Special thanks to Ken Alder, Ari Adland, Eric Perlmutter, Terry Quinn and Richard Davis. And to the musical group, His Majestys S...

A few months ago, Wendy Zukerman invited our own Latif Nasser to come on her show, and, of course, he jumped at the chance. Laughter ensued, as they set off to find the "The Funniest Joke in the World." When you just Google something like that, the internet might serve you, "What has many keys but can't open a single lock??” (Answer: A piano). So they had to dig deeper. According to science. And for this quest they interviewed a bunch of amazing comics incl...
Nov 22, 2024•43 min•Ep 614•Transcript available on Metacast 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 t...
Nov 15, 2024•47 min•Ep 613•Transcript available on Metacast As we grow up, there are little windows of time when we can learn very, very fast, and very, very deeply. Scientists call these moments, critical periods. Real, neurological, biological states when our brain can soak up information like a sponge. Then, these windows of learning close. Locking us in to certain behaviors and skills for the rest of our lives. But … what if we could reopen them? Today, we consider a series of discoveries that are reshaping our understanding of when and how we can le...
Nov 08, 2024•36 min•Ep 612•Transcript available on Metacast In an episode we first aired in 2014, we meet a man named Dennis Conrow, who was stuck. After a brief stint at college, he’d spent most of his 20’s back home with his parents, sleeping in his childhood room. And just when he finally struck out on his own, fate intervened. He lost both his parents to cancer. So Dennis was left, back in the house, alone. Until one night when a group of paranormal investigators showed up at his door and made him realize what it really means for a house, or a man, t...
Oct 31, 2024•31 min•Ep 611•Transcript available on Metacast As the US Presidential Election nears, Radiolab covers the closest we ever came to abolishing the Electoral College. In the 1960s, then-President Lyndon Johnson approached an ambitious young Senator known as the Kennedy of the Midwest to tweak the way Americans elect their President. The more Senator Birch Bayh looked into the electoral college the more he believed it was a ticking time bomb hidden in the constitution, that someone needed to defuse. With overwhelming support in Congress, the end...
Oct 25, 2024•1 hr•Ep 610•Transcript available on Metacast Back in 2018, when this episode first aired, there was a feeling that democracy was on the ropes. In the United States and abroad, citizens of democracies are feeling increasingly alienated, disaffected, and powerless. Some are even asking themselves a question that feels almost too dangerous to say out loud: is democracy fundamentally broken? Today on Radiolab, we ask a different question: how do we fix it? We scrutinize one proposed tweak to the way we vote that could make politics in this cou...
Oct 18, 2024•1 hr 10 min•Ep 608•Transcript available on Metacast In 1987, Gary Hart was a young charismatic Democrat, poised to win his party’s nomination and possibly the presidency. Many of us know the story of what happened next, and even if you don’t, it’s a familiar tale. Back in 2016, we examined how, when this happened, politicians and political reporters found themselves in uncharted territory. And with help from author Matt Bai, we looked at how the events of that May shaped the way we cover politics, and expanded our sense of what's appropriate when...

Co-host Lulu Miller is back with another season of her hit spinoff show Terrestrials , and to celebrate, we’re sharing the first episode with you. From stumps to snags, dead wood provides habitat for rodents, falcons, insects, and even humans.

First aired back in 2020, this episode follows the story of an octopus living one mile under the ocean as she performs a heroic act of heart and determination. In 2007, Bruce Robison’s robot submarine stumbled across an octopus settling in to brood her eggs. It seemed like a small moment. But as he went back to visit her, month after month, what began as a simple act of motherhood became a heroic ...
Sep 27, 2024•34 min•Ep 604•Transcript available on Metacast Today we follow a sleuth who has spent over a decade working to solve an epic mystery hiding in plain historical sight: did anyone survive the eruption of Mount Vesuvius in 79AD? Tired of hearing the conventional narrative that every Pompeiian perished without any evidence to back it up, Classicist Steven Tuck decides to look into it himself. Although he is nearly two millennia late to ground zero, he uses all the available evidence to reimagine the disaster from the perspective of the people on...
Sep 20, 2024•39 min•Ep 603•Transcript available on Metacast This episode first aired back in December of 2013, and at the start of that new year, the team was cracking open fossils, peering back into ancient seas, and looking up at lunar skies only to find that a year is not quite as fixed as we thought it was. With the help of paleontologist Neil Shubin, reporter Emily Graslie and the Field Museum's Paul Mayer we discover that our world is full of ancient coral calendars. Each one of these sea skeletons reveals that once upon a very-long-time-ago, years...
Sep 13, 2024•25 min•Ep 601•Transcript available on Metacast One man secretly hands off more and more of his life to an AI voice clone. Today, we feature veteran journalist Evan Ratliff who - for his new podcast Shell Game - decided to slowly replace himself bit by bit with an AI voice clone, to see how far he could actually take it. Could it do the mundane phone calls he’d prefer to skip? Could it get legal advice for him? Could it go to therapy for him? Could it parent his kids? Evan feeds his bot the most intimate details about his life, and lets the b...
Sep 06, 2024•54 min•Transcript available on Metacast First aired back in 2017, here’s a show of questions and, sometimes, answers. Cause, we get a lot of questions. Like, A LOT of questions. Tiny questions, big questions, short questions, long questions. Weird questions. Poop questions. We get them all. And over the years, as more and more of these questions arrived in our inbox, what happened was, guiltily, we put them off to the side, in a bucket of sorts, where they just sat around, unanswered. But now, we’re dumping the bucket out. Today, our ...

What happened that night at the local hospital, and crucially, what went wrong, would inspire a global sea-change in how emergency rooms operate and fundamentally alter the way doctors think in a crisis.

Today, we’re re-releasing a More Perfect episode that aired just after the October 2017 Las Vegas shooting. It is an episode that attempts to make sense of our country’s fraught relationship with the Second Amendment. For nearly 200 years of our nation’s history, the Second Amendment was an all-but-forgotten rule about the importance of militias. But in ...

In the first, a doctor gets a call — the hospital she works at is having an outbreak of unknown origin, in the middle of the worst wildfire season on record. In the second, an ecologist stands in a forest, watching it burn. Through very different circumstances, they both find themselves asking the same question: is there something in the smoke? This question will bring them together, and reveal – to all of us – a world we never saw before. This is the first episode in an ongoing seri...
Aug 09, 2024•27 min•Ep 594•Transcript available on Metacast We had a question back in 2007, about a thing every creature on the planet does--from giant humpback whales to teeny fruit flies. Why do we all sleep? What does it do for us, and what happens when we go without? We take a peek at iguanas sleeping with one eye open, get in bed with a pair of sleep-deprived new parents, and eavesdrop on the uneasy dreams of rats. We have some exciting news! In the “ Zoozve ” episode, Radiolab named its first-ever quasi-moon, and now it's your turn! Radiolab has te...
