Signal Hill: Caterpillar Roadshow

A couple years ago, an entomologist named Martha Weiss got a letter from a little boy in Japan saying he wanted to replicate a famous study of hers. We covered that original study on Radiolab more than a decade ago in an episode called Goo and You – check it out here – and in addition to revealing some fascinating secrets of insect life, it also raises big questions about memory, permanence and transformation. The letter Martha received about building on this study set in motion a series of spec...

Killer Empathy

In an episode first aired in 2012, Lulu Miller introduces us to Jeff Lockwood, a professor at the University of Wyoming, who spent a part of his career studying a particularly ferocious set of insects: Gryllacrididae. Or, as Jeff describes them, "crickets on steroids." They have crushingly strong, serrated jaws, and they launch all-out attacks on anyone who gets in their way--whether it's another cricket, or the guy trying to take them out of their cages. In order to work with the gryllacridids,...

Malthusian Swerve

Earth can sustain life for another 100 million years, but can we? In this episode, we partnered with the team at Planet Money to take stock of the essential raw materials that enable us to live as we do here on Earth—everything from sand to copper to oil— and tally up how much we have left. Are we living with reckless abandon? And if so, is there even a way to stop? This week, we bring you a conversation that’s equal parts terrifying and fascinating, featuring bird poop, daredevil drivers, and s...

Everybody's Got One

We all think we know the story of pregnancy. Sperm meets egg, followed by nine months of nurturing, nesting, and quiet incubation. this story isn’t the nursery rhyme we think it is. In a way, it’s a struggle, almost like a tiny war. And right on the front lines of that battle is another major player on the stage of pregnancy that not a single person on the planet would be here without. An entirely new organ: the placenta. In this episode, which we originally released in 2021, we take you on a jo...

Growth

It’s easy to take growth for granted, for it to seem expected, inevitable even. Every person starts out as a baby and grows up. Plants grow from seeds into food. The economy grows. That stack of mail on your table grows. But why does anything grow the way that it does? In this hour, we go from the Alaska State Fair, to a kitchen in Berkeley, to the deep sea, to ancient India, to South Korea, and lots of places in between, to investigate this question, and uncover the many forces that drive growt...

More Perfect: Sex Appeal

This episode explores Ruth Bader Ginsburg's strategic approach to achieving gender equality through law, focusing on the Craig v. Boren beer case. By challenging discriminatory laws against men, Ginsburg exposed underlying biases against women and subtly advanced women's rights. The story also highlights the personal journey of Carolyn Whitener, whose involvement in the case led to significant personal growth.

Revenge of the Miasma

Today we uncover an invisible killer hidden, for over a hundred years, by reasonable disbelief. Science journalist extraordinaire Carl Zimmer tells us the story of a centuries-long battle of ideas that came to a head, with tragic consequences, in the very recent past. His latest book, called Airborne, details a largely forgotten history of science that never quite managed to get off the ground. Along the way, Carl helps us understand how we can fail, over and over again, to see a truth right in ...

The Immortal Life of Henrietta Lacks

Today, a story that starts small and private, with one woman alone in her bathroom, as she makes a quiet, startling discovery about her own body. But that small, private moment grows and grows, and pretty soon it becomes something so big that it has impacted the life of every person reading this right now… and all that without the woman ever even knowing the impact she had. We originally aired this story back in 2010, but we thought we’d bring it back today, as questions about bodily autonomy ci...

Quantum Birds

Annie McEwen went to a mountain in Pennsylvania to help catch some migratory owls. Then Scott Weidensaul peeled back the owl’s feathery face disc, so that she could look at the back of its eyeball. No owls were harmed in the process, but this brief glimpse into the inner workings of a bird sent her off on a journey to a place where fleshy animal business bumps into the mathematics of subatomic particles. With help from Henrik Mouristen, we hear how one of the biggest mysteries in biology might f...

Vertigogo

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...

Forever Fresh

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...

Nukes

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...

The Darkest Dark

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...

Smarty Plants

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 ...

Match Made in Marrow

In an episode first reported in 2017, we bring you what may be, maybe the greatest gift one person could give to another. 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...

Curiosity Killed the Adage

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...

Dark Side of the Earth

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...

How Stockholm Stuck

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...

Less Than Kilogram

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...

Science Vs: The Funniest Joke in the World

When he rounded them up, he had a 100. 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...

Hello

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...

The Ecstasy of an Open Brain

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...

Haunted

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...

The Unpopular Vote

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...

Tweak the Vote

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...

Why Don't Sex Scandals Matter Anymore?

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...

Terrestrials: Stumpisode

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,...

Octomom

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 ...

A Little Pompeiian Fish Sauce Goes a Long Way

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...
