Radiolab is on a curiosity bender. We ask deep questions and use investigative journalism to get the answers. A given episode might whirl you through science, legal history, and into the home of someone halfway across the world. The show is known for innovative sound design, smashing information into music. It is hosted by Lulu Miller and Latif Nasser.
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.
We have some exciting news! In the “Zoozve” episode, Radiolab named its first-ever quasi-moon, and now it's your turn! Radiolab has teamed up with The International Astronomical Union to launch a global naming contest for one of Earth’s quasi-moons. This is your chance to make your mark on the heavens.

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 learn. And what that could mean for things like PTSD, brain disease, or strokes. And cuddle puddles. It’s a mind-bending discussion. Literally and figuratively.
This is the second episode in an ongoing series hosted by Molly Webster, in conversation with scientists and science-y people, doing work at the furthest edges of what we know. You can find the first episode here. More to come!

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, to be haunted.

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 endorsement of multiple Presidents, and polling showing that over 80% of the American public supported abolishing it, it looked like he might just pull it off. So why do we still have the electoral college? And will we actually ever get rid of it?

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 country more representative, more moderate, and most shocking of all, more civil. Could this one surprisingly do-able mathematical fix really turn political campaigning from a rude bloodsport to a campfire singalong? And even if we could do that, would we want to?
Special thanks to Rob Richie (and everyone else at Fairvote), Don Saari, Diana Leygerman, Caroline Tolbert, Bobby Agee, Edward Still, Jim Blacksher, Allen Caton, Nikolas Bowie, John Hale, and Anna Luhrmann and the rest of the team at the Varieties of Democracy Institute in Sweden.
And a very special thanks to Rick Pickren, for allowing us to use his rendition of State of Maine, Maine’s state anthem. Check that out, and all his other state anthems on Spotify or Youtube.

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 it comes to judging a candidate.
In the wake of the 2016 election, and in the throes of our current political moment, it would seem we’ve come full circle in the weirdest way. So we sat down with Brooke Gladstone, co-host of our sister show here at WNYC, On the Media, to talk about why sex scandals don’t matter anymore.

As dead as they seem, tree stumps are hubs of life and relationships.
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. Stumps hold together the forest floor, give hunting perches to birds of prey in flatlands, prevent erosion and the encroachment of invasive species, usher in sunlight, provide nutrients, store renewable fuel, and hold onto stories human beings might have forgotten. Without these ghosts of trees past, nothing would be the same. Scottish author, artist and lover of tree stumps, Dr. Amanda Thomson, leads Lulu on a “tour de stumps,” a journey across space and time to learn about some of the most magical stumps on the planet.

A mile under the ocean, we get to watch an octopus perform a heroic act of heart and determination.
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 feat that has never been equaled by any known species on Earth.
This episode was reported and produced by Annie McEwen.

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 the ground. Could anyone have survived the volcano? If they did, could they have survived what came after that: earthquakes, tsunamis, pumice stones hurtling like missiles from the sky? If someone did survive, what happened to them after that??! To find out we have to think, feel and possibly even eat like Ancient Romans.
An against-all-odds story of a disaster without warning, a mass disappearance without a trace, and oddly, a particularly stinky fish sauce, care of special guest Chef Samin Nosrat.

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 were shorter by over forty days. And astrophysicist Chis Impey helps us comprehend how the change is all to be blamed on a celestial slow dance with the moon.
Plus, Robert indulges his curiosity about stopping time and counteracting the spinning of the spheres by taking astrophysicist Neil deGrasse Tyson on a (theoretical) trip to Venus with a rooster and sprinter Usain Bolt.

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 bot loose in high-stakes situations at home and at work. Which bizarro version of him will show up? The desperately-agreeable conversationalist, the crank-yanking prank caller, the glitched out stranger who sounds like he’s in the middle of a mental breakdown, or someone else entirely? Will people believe it’s really him? And how will they act if they don’t? A gonzo journalistic experiment for the age of AI, that’s funny and eerie all at the same time.
