Tweak the Vote (Nov 5th, 2018)

Democracy is 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, just a day before the American midterm elections, 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 repr...

War of the Worlds (Oct 30th, 2018)

It's been 80 years to the day since Orson Welles' infamous radio drama "The War of the Worlds" echoed far and wide over the airwaves. So we want to bring you back to our very first live hour, where we take a deep dive into what was one of the most controversial moments in broadcasting history. "The War of the Worlds," a radio play about Martians invading New Jersey, caused panic when it originally aired, and it's continued to fool people since--from Santiago, Chile to Buffalo, New York to a p...

In the No Part 3 (Oct 26th, 2018)

In the final episode of our “In The No” series, we sat down with several different groups of college-age women to talk about their sexual experiences. And we found that despite colleges now being steeped in conversations about consent, there was another conversation in intimate moments that just wasn't happening. In search of a script, we dive into the details of BDSM negotiations and are left wondering if all of this talk about consent is ignoring a larger problem.

In the No Part 2 (Oct 19th, 2018)

In the year since accusations of sexual assault were first brought against Harvey Weinstein, our news has been flooded with stories of sexual misconduct, indicting very visible figures in our public life. Most of these cases have involved unequivocal breaches of consent, some of which have been criminal. But what have also emerged are conversations surrounding more difficult situations to parse ones that exist in a much grayer space. When we started our own reporting through this gray zone,...

In the No Part 1 (Oct 11th, 2018)

In 2017, radio-maker Kaitlin Prest released a mini-series called "No" about her personal struggle to understand and communicate about sexual consent. That show, which dives into the experience, moment by moment, of navigating sexual intimacy, struck a chord with many of us. It's gorgeous, deeply personal, and incredibly thoughtful. And it seemed to presage a much larger conversation that is happening all around us in this moment. And so we decided to embark, with Kaitlin, on our own explorati...

Breaking Bad News Bears (Sep 28th, 2018)

Today, a challenge: bear with us.


We decided to shake things up at the show so we threw our staff a curveball, Walter Matthau-style. In two weeks time we told our producers to pitch, report, and produce stories about breaking news….or bears. What emerged was a sort of love letter for our honey-loving friends and a discovery that they embody so much more than we could have imagined: a town’s symbol for hope, a celebrity, a foe, and a clue to future ways we’ll deal with our changing environment....

Infective Heredity (Sep 21st, 2018)

Today, a fast moving, sidestepping, gene-swapping free-for-all that would’ve made Darwin’s head spin.


David Quammen tells us about a shocking way that life can evolve - infective heredity. To figure it all out we go back to the earliest versions of life, and we revisit an earlier version of Radiolab. After reckoning with a scientific icon, we find ourselves in a tangle of genes that sheds new light on peppered moths, drug-resistant bugs, and a key moment in the evolution of life when mammals w...

27: The Most Perfect Album (Sep 19th, 2018)

More Perfect is back with something totally new and exciting. They just dropped an ALBUM. 27: The Most Perfect Album is like a Constitutional mix-tape, a Schoolhouse Rock for the 21st century. The album features original tracks by artists like Dolly Parton, Kash Doll, and Devendra Banhart: 27+ songs inspired by the 27 Amendments. Alongside the album they'll be releasing short stories deep-diving into each amendment's history and resonance. In this episode, we preview a few songs and dive into...

Baby Blue Blood Drive (Aug 29th, 2018)

Horseshoe crabs are not much to look at.  But beneath their unassuming catcher’s-mitt shell, they harbor a half-billion-year-old secret: a superpower that helped them outlive the dinosaurs and survive all the Earth’s mass extinctions.  And what is that secret superpower? Their blood. Their baby blue blood.  And it’s so miraculous that for decades, it hasn’t just been saving their butts, it’s been saving ours too.


But that all might be about to change.  


Follow us as we follow these ancient crit...

Post No Evil (Aug 17th, 2018)

Back in 2008 Facebook began writing a document. It was a constitution of sorts, laying out what could and what couldn’t be posted on the site. Back then, the rules were simple, outlawing nudity and gore. Today, they’re anything but. 


How do you define hate speech? Where’s the line between a joke and an attack? How much butt is too much butt? Facebook has answered these questions. And from these answers they’ve written a rulebook that all 2.2 billion of us are expected to follow. Today, we expl...

The Bad Show (Jul 28th, 2018)

With all of the black-and-white moralizing in our world today, we decided to bring back an old show about the little bit of bad that's in all of us...and the little bit of really, really bad that's in some of us.  


Cruelty, violence, badness... in this episode we begin with a chilling statistic: 91% of men, and 84% of women, have fantasized about killing someone. We take a look at one particular fantasy lurking behind these numbers, and wonder what this shadow world might tell us about ourselv...

Gonads: Sex Ed (Jul 27th, 2018)

If there’s one thing Gonads taught us, it’s just how complicated human reproduction is. All the things we thought we knew about biology and sex determination are up for debate in a way that feels both daunting and full of potential. At the same time, we're at a moment where we’re wrestling with how to approach conversations around sex, consent, and boundaries, at a time that may be more divisive than ever. So host Molly Webster thought: what if we took on sex ed, and tried to tackle questions...

Gonads: Dana (Jul 22nd, 2018)

When Dana Zzyym applied for their first passport back in 2014, they were handed a pretty straightforward application. Name, place of birth, photo ID -- the usual. But one question on the application stopped Dana in their tracks: male or female? Dana, technically, wasn’t either.


In this episode, we follow the story of Dana Zzyym, Navy veteran and activist, which starts long before they scribble the word "intersex” on their passport application. Along the way, we see what happens when our inner ...

Gonads: Dutee (Jul 22nd, 2018)

In 2014, India’s Dutee Chand was a rising female track and field star, crushing national records. But then, that summer, something unexpected happened: she failed a gender test. And was banned from the sport. Before she knew it, Dutee was thrown into the middle of a controversy that started long before her, and continues on today: how to separate males and females in sport.


This story is a companion piece to Gonads, Episode 5, Dana


"Dutee" was reported by Molly Webster, with co-reporting and ...

Gonads: X & Y (Jun 30th, 2018)

A lot of us understand biological sex with a pretty fateful underpinning: if you’re born with XX chromosomes, you’re female; if you’re born with XY chromosomes, you’re male. But it turns out, our relationship to the opposite sex is more complicated than we think.


This episode was reported by Molly Webster, and produced by Matt Kielty. With scoring, original composition and mixing by Matt Kielty and Alex Overington. Additional production by Rachael Cusick, and editing by Pat Walters. The “Balla...

Gonads: Fronads (Jun 23rd, 2018)

At 28 years old, Annie Dauer was living a full life. She had a job she loved as a highschool PE teacher, a big family who lived nearby, and a serious boyfriend. Then, cancer struck. Annie would come to find out she had Stage 4 non-Hodgkin's lymphoma. It was so aggressive, there was a real chance she might die. Her oncologists wanted her to start treatment immediately. Like, end-of-the-week immediately. But before Annie started treatment, she walked out of the doctor’s office and crossed the s...

Gonads: The Primordial Journey (Jun 15th, 2018)

At two weeks old, the human embryo has only just begun its months-long journey to become a baby. The embryo is tiny, still invisible to the naked eye. But inside it, an epic struggle plays out, as a nomadic band of cells marches toward a mysterious destiny, with the future of humanity resting on their microscopic shoulders.

Birthstory (Jun 8th, 2018)


We originally posted this episode in 2015, and it inspired producer Molly Webster to take a deep dive into the wild and mysterious world of human reproduction. Starting next week, she’ll be taking over the Radiolab podcast feed for a month to present a series of mind-bending stories that make us rethink the ways we make more of us.



You know the drill - all it takes is one sperm, one egg, and blammo - you got yourself a baby. Right? Well, in this episode, conception takes on a new form - it’s t...

Poison Control (Jun 1st, 2018)

When reporter Brenna Farrell was a new mom, her son gave her and her husband a scare -- prompting them to call Poison Control. For Brenna, the experience was so odd, and oddly comforting, that she decided to dive into the birth story of this invisible network of poison experts, and try to understand the evolving relationship we humans have with our poisonous planet. As we learn about how poison control has changed over the years, we end up wondering what a place devoted to data and human conn...

Unraveling Bolero (May 22nd, 2018)

This week, we're throwing it back to an old favorite: a story about obsession, creativity, and a strange symmetry between a biologist and a composer that revolves around one famously repetitive piece of music.


Anne Adams was a brilliant biologist. But when her son Alex was in a bad car accident, she decided to stay home to help him recover. And then, rather suddenly, she decided to quit science altogether and become a full-time artist. After that, her husband Robert Adams tells us, she just pa...
