Snail Sex Tape
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.
Special thanks to Menno Schilthuizen and Aaron Chase.

Black Box
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.

Gray's Donation
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 We originally made this story back in 2015, but we wanted to play it again because we love that it brings a view of science that is redemptive, tender, and unexpected.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.

Time is Honey
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://zpr.io/ePxaaYja6YF4).

Kleptotherms
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.

Song of the Cerebellum
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.

You and Me and Mr. Self-Esteem
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?

The Punchline
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.

Brain Balls
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?

Moon Trees
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.

Fertility Cliff
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.

The Good Show
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?

Shell Game: Minimum Viable Company
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. You can sign up to get the rest of the Shell Game ad-free, and the Shell Game newsletter, at shellgame.co .

Fela Kuti: Enter the Shrine
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.

Our Common Nature: West Virginia Coal
Today on the show, we’re bringing you an episode from Our Common Nature (https://link.podtrac.com/v7mx144d), a new podcast series where cellist Yo-Yo Ma and host Ana González travel around the United States to meet people, make music and better understand how culture binds us to nature. The series features a few familiar voices, including Ana González (host) and Alan Goffinski (producer), from our kids podcast, Terrestrials (https://link.podtrac.com/vysacqn1).
About the episode:
West Virginia is defined by its beauty and its coal, two things that can work against each other. Yo-Yo Ma felt this as soon as stepped foot in its hills.This episode explores how music and poetry help process the emotions of a community besieged with disaster and held together by pride and duty. We travel down the Coal River with third-generation coal miner Chris Saunders, who tells us how coal has saved and threatened his life. Poet Crystal Good shares her poetry, which channels her rage and love. And musician and granddaughter of West Virginia coal miners, Kathy Mattea, explains the beauty of belting out your home state in a chorus. The end of the episode finds host Ana floating down the New River with help from a group of high schoolers and Yo-Yo Ma.Listen to the full series Our Common Nature (https://link.podtrac.com/v7mx144d).
Featuring music by Yo-Yo Ma, Dom Flemons, and Kathy Mattea and poetry by Crystal Good.

Quantum Refuge
Qasem Waleed is a 28-year-old physicist who has lived in Gaza his whole life. In 2024, he joined a chorus of Palestinians sharing videos and pictures and writing about the chaos and violence they were living through, as Israel’s military bombardment devastated their lives. But Qasem was trying to describe his reality through the lens of the most notoriously confusing and inscrutable field of science ever, quantum mechanics. We talked to him, from a cafe near the Al-Mawasi section of Gaza, to find out why. And over the course of several conversations, he told us how this reality-breaking corner of science has helped him survive. And how such unspeakable violence actually let him understand, in a visceral way, quantum mechanics’ most counter-intuitive ideas.

The Wubi Effect
When we think of China today, we think of a technological superpower. From Huawei and 5G to TikTok and viral social media, China is stride for stride with the United States in the world of computing. However, China’s technological renaissance almost didn’t happen. And for one very basic reason: the Chinese language, with its 70,000 plus characters, couldn’t fit on a keyboard.
Today, we tell the story of Professor Wang Yongmin, a hard-headed computer programmer who solved this puzzle and laid the foundation for the China we know today.

The Glow Below
A call to oceanographer Edie Widder about a fish with a very odd immune system quickly becomes something else: a dive into the deep sea, into a world of brilliant light. But down there, the light doesn’t behave like light -- it sparkles and glows, but also drips, squirts, and dribbles. Today, find out how creatures make the light and how they use it, from hunting and hiding to maybe even … talking. And hear about a series of mysterious moments where Edie goes from studying the creatures to becoming one of them.

What Up Holmes?
Love it or hate it, the freedom to say obnoxious and subversive things is the quintessence of what makes America America. But our say-almost-anything approach to free speech is actually relatively recent, and you can trace it back to one guy: a Supreme Court justice named Oliver Wendell Holmes. Even weirder, you can trace it back to one seemingly ordinary eight-month period in Holmes’s life when he seems to have done a logical U-turn on what should be say-able. Why he changed his mind during those eight months is one of the greatest mysteries in the history of the Supreme Court. (Spoiler: the answer involves anarchists, a house of truth, and a cry for help from a dear friend.) Join us in an episode we originally released in 2021, as we investigate why he changed his mind, how that made the country change its mind, and whether it’s now time to change our minds again.

Creation Story
Ella al-Shamahi is one part Charles Darwin, one part Indiana Jones. She braves war zones and pirate-infested waters to collect fossils from prehistoric caves, fossils that help us understand the origin of our species. Her recent hit BBC / PBS series Human follows her around the globe trying to piece together the unlikely story of how early humans conquered the world. But Ella’s own origins as an evolutionary biologist are equally unlikely. She sits down with us and tells us a story she has rarely shared publicly, about how she came to believe in evolution, and how much that belief cost her.

Adoptive Couple v. Baby Girl
This is the story of a three-year-old girl and the highest court in the land. The Supreme Court case Adoptive Couple v. Baby Girl is a legal battle that has entangled a biological father, a heart-broken couple, and the tragic history of Native American children taken from their families. We originally released this story back in 2013, when that girl’s fate was still in the balance of various legal decisions. We thought now was a good time to bring the story back, because the Act at the center of the story is still being questioned.
When then-producer Tim Howard first read about this case, it struck him as a sad but seemingly straightforward custody dispute. But, as he started talking to lawyers and historians and the families involved in the case, it became clear that it was much more than that. Because Adoptive Couple v. Baby Girl challenges parts of the 1978 Indian Child Welfare Act, this case puts one little girl at the center of a storm of legal intricacies, Native American tribal culture, and heart-wrenching personal stakes.

Voice
Over the course of millions of years, human voices have evolved to hold startling power. These clouds of vibrating air carry crucial information about who we are–and we rely on them to push ourselves up and out into the physical world.
This week, we’re on a journey to understand how we got our unique sonic fingerprint, the power it affords us, and what happens when it’s taken away.

The Spark of Life
In the 1920s, a Russian biologist studying onion roots made a surprising discovery: underground, down in the darkness, it seemed like the cells inside the onion roots were making their own … light.
The “onion root experiment” went on to become something of a cult classic in science, and eventually the biologically-made light was dubbed “biophotons.” In the ensuing century, biophoton discoveries moved from onion roots to bacteria, frog embryos, and humans. Today, scientist Nirosha Murugan is on a career-defining journey to learn more about the light. As she and her colleagues study this mysterious phenomenon, they find themselves racing from question to question, wondering what gives off light, where it might be coming from, and what, if anything, it could tell us about life, disease, and even death.
Correction: In this episode, when Nirosha spoke about her melanoma study, she misstated the lab animal involved in the study. It was mice.

Los Frikis
How a group of 80’s Cuban misfits found rock-and-roll and created a revolution within a revolution, going into exile without ever leaving home. Reporter Luis Trelles brings us the story of punk rock’s arrival in Cuba and a small band of outsiders who sentenced themselves to death and set themselves free. We originally released this episode back in 2015 in a collaboration with Radio Ambulante, but the story is so fascinating (and, in many ways, still relevant) that we haven’t stopped thinking about it.
Special thanks to the bands VIH, Eskoria, Metamorfosis and Alio Die & Mariolina Zitta for the use of their music.

Screaming Into the Void
In August we performed a live taping of the show from a theater perched on the edge of Manhattan, overlooking the Hudson River, overshadowed by the wide open night sky. Three stories about voids. One about a fish that screams into the night – and the mystery of its counterpart that doesn’t. Another about a group of women who gazed at the night sky and taught us just how vast the universe is, and a third about a man who talk to aliens – and the people who tell him he’s putting human civilization at risk by doing so. Finally, we turn back to Earth with the help of a reading from Samantha Harvey’s hit novel Orbital (https://zpr.io/RNi4sY2JVKxK) performed by the artist, actor and podcast host Helga Davis (https://zpr.io/TKGuzzDFnVjN). What does it mean to stand on the edge of a void, and what happens when you scream into it, or choose not to?

Music Hat
With this episode, we’re putting on our music hat. For a program that relies so much on scoring and sound, it’s not often we talk about the musicians and the music they make that inspire us. Today, that changes. Today, we bring you two stories. Each about musicians that our former host and creator of Radiolab, Jad Abumrad, loves.
We originally released these stories many years ago, and both start deep in music itself. Then quickly, they dig deeper — into our relationships with technology, and ourselves.We start with the band Dawn of Midi, who straddle the intersection between acoustic and electronic sounds. Jad talks to the band about their album, Dysnomia, and how it's filled with heavily-layered rhythms that feel both mechanistic and deeply human, at the same time.
Then, Jad talks with Juana Molina, an Argentine singer who accidentally became a famous actress, when all along all she really wanted was to be a musician.
Special thanks to Dawn of Midi and Juana Molina.

The Medical Matchmaking Machine
As he finished his medical school exam, David Fajgenbaum felt off. He walked down to the ER and checked himself in. Soon he was in the ICU with multiple organ failure. The only drug for his condition didn’t work. He had months to live, if that. If he was going to survive, he was going to have to find his own cure. Miraculously, he pulled it off in the nick of time. From that ordeal, he realized that our system of discovering and approving drugs is far from perfect, and that he might be able to use AI to find dozens, hundreds, even thousands of cures, hidden in plain sight, for as-yet untreatable diseases.

Weighing Good Intentions
In an episode first released in 2010, then-producer Lulu Miller drives to Michigan to track down the endangered Kirtland’s warbler. Efforts to protect the bird have lead to the killing of cowbirds (a species that commandeers warbler nests), and a prescribed burn aimed at creating a new habitat. Tragically, this burn led to the death of a 29-year-old wildlife technician who was dedicated to warbler restoration. Forest Service employee Rita Halbeisen, local Michiganders skeptical of the resources put toward protecting the warbler, and the family of James Swiderski (the man killed in the fire), weigh in on how far we should go to protect one species.
