St. Patricks day is coming up. People worldwide will wear leprechaun hats and celebrate the luck of the Irish. But what about the luck of lobsters? Today we have a story about the biggest, luckiest lobster we have ever heard of — Nick. As lobsters age, they keep growing bigger and bigger. They don’t wear out or get sick like most other creatures do. The most common way they die is through accidents. One day a woman named Bonnie went to her nearby grocery store and saw behemoth Nick cramped in a ...
Mar 06, 2025•15 min•Transcript available on Metacast When wildlife conservationist Alan Rabinowitz was a boy, he had a stutter. Strangely, his stutter vanished when he spoke to animals. One day, when his father took him to the Bronx Zoo, Alan saw a majestic jaguar and made a promise to it. He spent the rest of his life fulfilling that promise. Read Alan Rabinowitz’s picture book: “ A Boy and a Jaguar .” Radiolab was created by Jad Abumrad and is edited by Soren Wheeler. Lulu Miller and Latif Nasser are our co-hosts. Dylan Keefe is our director of ...
Feb 20, 2025•16 min•Transcript available on Metacast Next week is Valentine’s Day, but instead of talking about falling in love, we’re going to talk about falling cats and barrels. First, writer David Quammen tells us about a strange observation: cats are falling out of buildings in New York City. When a cat falls from less than five stories or more than nine stories, it usually survives. But when it falls from between five and nine stories, it suffers serious injury. Why? Physics has the answer. Then we meet Annie Taylor, the first person who wen...
Feb 06, 2025•17 min•Transcript available on Metacast On January 29, in places like China, Malaysia, Korea and Chinatowns across the globe, dragons will rise in the form of massive puppets. Today we bring you a special Terrestrials episode on dragons to understand what they have to do with the New Year, what the dragon myth means, and explore the tiny chance that dragons could have ever been real.

Jan 23, 2025•26 min•Ep 14•Transcript available on Metacast Today we bring you an episode from our friends over at The Big Fib . In the era of fake news, kids need to learn to be able to tell what’s true from what’s false. And what better way to do that than a game show that puts kids in the driver’s seat, adults in the hot seat, and a sound-effects robot strapped to the roof? Each week, a kid interviews one fake and one real expert on a particular topic and they have to figure out who’s the true expert and who’s a liar. In this episode, they interview t...
Jan 16, 2025•36 min•Transcript available on Metacast For centuries, the stomach was a black box to humans. We didn’t understand the mystery of what happened to food after it went inside us. That is, until the early 1800s, when Dr. William Beaumont found a boy, Alexis St. Martin, with a hole in his stomach. Writer Mary Roach brings us that story. She first sticks her hand inside the stomach of a live cow and then tells us how Beaumont conducted experiments on St. Martin to understand how the stomach breaks down food. This strange relationship betwe...
Jan 09, 2025•21 min•Transcript available on Metacast To celebrate New Year’s Day, there are all kinds of traditions. Some people eat black eyed peas for good luck, some list out resolutions. But here at Terrestrials, we are taking a cue from the wisdom of pets, who are so, so, so good at sleeping. After a short preamble from Lulu, we’ll turn the microphone over to listeners’ furry friends snoring and snoozing in various positions, places, and locations. The piece will be largely wordless, with some narration from listeners describing their pets, a...
Jan 01, 2025•29 min•Transcript available on Metacast The year’s best celestial event was, without a doubt, April’s solar eclipse. The moon went in front of the sun to cast a 115 mile wide shadow on Earth. A swathe of North America was showered in sudden darkness. In honor of the eclipse, the Radiolab team made a show about the star of the show: the moon. We think we know the moon — we know that humanity visited it, that it’s a shiny white rotating rock in the sky. But what else really? In today’s episode, the team tells us about the moon’s formati...
Dec 26, 2024•30 min•Transcript available on Metacast Today we bring you an episode from our friends over at Atlas Obscura . It's about something that for centuries people thought was a tall tale, something sailors would occasionally spot out in the waves like mermaids or the Loch Ness monster, but most people on the land didn't think was real. Until one day, when a satellite in the sky was able to solve the case. Host Dylan Thuras tells us the story of a satellite scientist and a ship captain in search of gigantic swaths of bioluminescence that ra...
Dec 19, 2024•19 min•Transcript available on Metacast In less than 10 days, the world will witness the winter solstice, or the shortest day of the year. Half of the Earth will be tilted the farthest away from the sun, and we will plunge into the dark. So today we thought we’d play another story about the dark. One of the darkest places in the universe actually: a black hole. But not just any black hole, a really tiny black hole, the size of an atom. We start the story on a calm morning in Siberia. All of a sudden, a large ball of fire appears in th...
Dec 12, 2024•29 min•Transcript available on Metacast Radiolab co-host Latif Nasser was putting his child to sleep one day when he noticed a poster of the solar system on the wall. It showed that Venus had a moon called Zoozve. When he looked it up, the internet told him that Venus did not have a moon. And searching “Zoozve” gave him a bunch of Czech results about zoos. This moment sets Latif off on a curiosity odyssey. What is the mystery behind this moon? Turns out, it’s both a moon and not a moon. And we get to name one. And now that you know al...
Dec 05, 2024•29 min•Transcript available on Metacast We start this story off with a question. Are human beings innately violent? Then we head to East Africa with Stanford neuroscientist Robert Sapolsky , who spent his summers studying wild baboons there. Baboons are a textbook example of a hierarchical, male-dominated, and aggressive society. But one day, Sapolsky noticed that a troop of baboons became unexpectedly gentle. They deviated from the usual aggressiveness so characteristic of them and groomed each other. The key question was how do thes...
Nov 28, 2024•16 min•Transcript available on Metacast We start off in a cathedral full of animals – hermit crabs, parrots, hamsters, dogs, cats and bunnies – being blessed. We then wonder, do the animals feel grace? What do we really know about what goes on inside an animal’s mind? Do they also experience gratitude, despair or anger? How much emotionality do humans and animals share? And can we measure it? We get the story of a rescued whale that may have found a way to say thanks to its rescuers. And then we speak to behavioral scientist Clive Wyn...
Nov 14, 2024•24 min•Transcript available on Metacast Artist Ashley (Ash) Eliza Williams was so shy growing up that they found it hard to speak to people. Instead, they withdrew from the world of humans and found comfort in the forest, where they spent hours exploring, scavenging, and collecting — eventually discovering lichen. They began painting portraits of lichen’s wild, colorful, and fuzzy shapes. In time, Ash learned that lichen is actually a composite organism, a mixture of two species — algae and fungi — working together to live. This idea ...
Oct 31, 2024•27 min•Ep 13•Transcript available on Metacast Have you ever seen an island on a lake? On an island? On a lake? On another island? Josh Calder has. Working in a dusty room of a library, he first saw one on a map, and has been fascinated with these “recursive islands” ever since. Song bud Alan Goffinski takes us on a wild journey into these secret bullseyes hiding all over planet Earth. We learn from ecologist Elba Montes why recursive islands breed species found nowhere else on Earth, and thus are hotbeds of evolution. Check out Josh Calder’...
Oct 24, 2024•25 min•Ep 12•Transcript available on Metacast BLAST OFF! NASA just sent a spacecraft to Europa, one of Jupiter's moons, and on the side of that spacecraft, they included a poem. Not just any poem — a poem by U.S. Poet Laureate Ada Limón. A poem that’s supposed to represent all of humanity to the universe. No biggie. Host Lulu Miller opens up the floor to kids from all over the country to ask Limón and NASA scientist Cynthia Phillips questions about the mission, outer space, poetry and what a space slushie might taste like. Listen to find ou...
Oct 17, 2024•42 min•Ep 11•Transcript available on Metacast The Greenland shark is ugly. Its eyes look cloudy and dead. Its snout and fins are stubby. Its meat is poisonous. And that may be part of why most people have overlooked these sharks for so long. But there was a rumor circulating among Greenland villagers that this deepsea dweller could survive for centuries. Scientist John Steffensen went on a hunt to see if this was true and discovered that the Greenland shark can live for more than 500 years, making it the longest living vertebrate on the pla...
Oct 10, 2024•27 min•Ep 10•Transcript available on Metacast The honeybee. The ever-important pollinator for our plants is disappearing. Some call it the silence of the bees, others call it colony collapse disorder. Dr. Sammy Ramsey, our official bug correspondent, wondered, could it be due to parasites? And if so, how do we catch all of them? This question takes Dr. Sammy to the heart of a jungle in Bangladesh to look for overlooked honeybees impervious to parasites. The only problem? He can't find them. With help from a local guide named Babulall, he le...
Oct 03, 2024•27 min•Ep 9•Transcript available on Metacast Middle schooler, Aanya, has an up-close encounter with a squirrel in the school yard, which leads her to an obsession with one of North America's most common critters. She tells host Lulu Miller all about the overlooked superpowers of squirrels, including one squirrel who lives way up in the Arctic, where the weather gets so cold the squirrels who live there drop their body temperatures down below freezing and somehow, miraculously, survive. Host Lulu travels to Alaska to meet one of these squir...
Sep 26, 2024•24 min•Ep 8•Transcript available on Metacast As dead as they seem, tree stumps are hubs of life and relationships. From stumps to snags, deadwood 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, can be wells of renewable fuel, and hold onto stories human beings might have forgotten. Without these ghosts of trees past, nothing would be the s...

May 09, 2024•2 min•Ep 8•Transcript available on Metacast In the game of life, every species is like an action figure. You got your dogs and your dung beetles, your bald eagles and your blueberries. And for a long time scientists believed it was pretty much impossible for those action figures to mix and make a new kind of action figure that was able to have its own babies (dog beetles? Baldberries? Nah). But, today we tell the story of a four-legged beast in Kentucky whose existence is upending scientific beliefs. If you want a big fat SPOILER, here it...
