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 8-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...

Scientists took about 300 years to lay out the Periodic Table into neat rows and columns. In one hour, we’re going to mess it all up.  This episode, we enlist journalists, poets, musicians, and even a physicist to help us tell stories of matter that matters. You’ll never look at that chart the same way again. Special thanks to Emotive Fruition for organizing poetry performances and to the mighty Sylvan Esso for composing 'Jaime's Song', both inspired by this episode. Thanks also to Sam Kean,...

As we hit the one year mark since the first U.S. state (California) issued a stay-at-home order to prevent the spread of COVID-19, we put out a call to see if any of you would take us to your secret escape spot and record audio there. And you astounded us with what you brought in.  In this soundrich, kaleidoscopic episode, we journey around the planet and then, quite literally, beyond it. Listen only if you want a boatload of fresh air, fields of wildflowers, stars, birds, frogs, and a...

Last summer, at a hospital in England, a man in his 70s being treated for complications with cancer tested positive for covid-19. He had lymphoma, and the disease plus his drugs weakened his immune system, making him particularly susceptible to the virus. He wasn’t too bad off, considering, and was sent home. That was Day 1. This is the story of what the doctors witnessed, over the course of his illness: the evolution of covid-19 inside his body. Before their eyes, they get a hint of what...

In November of 2016, journalist Morgen Peck showed up at her friend Molly Webster's apartment in Brooklyn, told her to take her battery out of her phone, and began to tell her about The Ceremony, a moment last fall when a group of, well, let's just call them wizards, came together in an undisclosed location to launch a new currency. It's an undertaking that involves some of the most elaborate security and cryptography ever done (so we've been told). And math. Lots of math. It was all going...

It was the early 80s, the height of the Cold War, when something strange began happening off the coast of Sweden. The navy reported a mysterious sound deep below the surface of the ocean. Again, and again, and again they would hear it near their secret military bases, in their harbors, and up and down the Swedish coastline.  After thorough analysis the navy was certain. The sound was an invasion into their waters, an act of war, the opening salvos of a possible nuclear annihilation.  Or was...

Since its inception, the perennial thorn in Facebook’s side has been content moderation. That is, deciding what you and I are allowed to post on the site and what we’re not. Missteps by Facebook in this area have fueled everything from a genocide in Myanmar to viral disinformation surrounding politics and the coronavirus. However, just this past year, conceding their failings, Facebook shifted its approach. They erected an independent body of twenty jurors that will make the final call on...

Candid Camera is one of the most original – and one of the most mischievous – TV shows of all time.  Admirers hailed its creator Allen Funt as a poet of the everyday. Critics denounced him as a Peeping Tom.  Funt sought to capture people at their most unguarded, their most spontaneous, their most natural.  And he did. But as the show succeeded, it started to change the way we thought not only of reality television, but also of reality itself.  Looking back at the show now, a half century...

We’re all still processing what happened on January 6th. Despite the hours and hours of video circulating online, we still didn’t feel like we had a visceral, on-the-ground sense of what happened that day. Until we heard the piece we’re featuring today. The Washington Post’s daily podcast Post Reports built a minute-by-minute replay of that day, from the rally, to the invasion, to the aftermath, told through the voices of people who were in the building that day -- reporters,...

Back in March 2020, when the COVID-19 pandemic was just beginning and the shelter-in-place orders brought the economy to a screeching halt, a quirky-but-clever idea to save the economy made its way up to some of the highest levels of government. Congresswoman Rashida Tlaib proposed an ambitious relief bill to keep the country’s metaphorical lights on: recurring payments to people to help them stay afloat during the crisis. And the way Congress would pay for it? By minting two platinum $1...

As the attacks were unfolding on the Capitol, a steady stream of images poured onto our screens. Photo editor Kainaz Amaria tells us what she was looking for--and seeing--that afternoon. And she runs into a dilemma we've talked about before. In December of 2009, photojournalist Lynsey Addario, in was embedded with a medevac team in Afghanistan. After days of waiting, one night they got the call - a marine was gravely wounded. What happened next happens all the time. But this time it was...

This year was the worst. And as our staff tried to figure out what to do for our last episode of 2020, co-host Latif Nasser thought, what if we stare straight into the darkness … and make a damn Christmas special about it. Latif begins with a story about Santa, and a back-room deal he made with the Trump administration to jump to the front of the vaccine line, a tale that travels from an absurd quid-pro-quo to a deep question: who really is an essential worker?  From there, we take a...

A global pandemic. An afflicted, angry group. A seemingly indifferent government. Reporter Tracie Hunte wanted to understand this moment of pain and confusion by looking back 30 years, and she found a complicated answer to a simple question: When nothing seems to work, how do you make change? This episode was reported by Tracie Hunte, and produced by Annie McEwen and Tobin Low. Fact-checking by Diane Kelly.  Support Radiolab by becoming a member today at Radiolab.org/donate.    

Should the U.S. Supreme Court be the court of the world? In the 18th century, two feuding Frenchmen inspired a one-sentence law that helped launch American human rights litigation into the 20th century. The Alien Tort Statute allowed a Paraguayan woman to find justice for a terrible crime committed in her homeland. But as America reached further and further out into the world, the court was forced to confront the contradictions in our country’s ideology: sympathy vs. sovereignty. Earlier this...

Until now, the fastest vaccine ever made - for mumps - took four years. And while our current effort to develop a covid-19 vaccine involves thousands of people working around the clock, the mumps vaccine was developed almost exclusively by one person: Maurice Hilleman. Hilleman cranked out more than 40 other vaccines over the course of his career, including 8 of the 14 routinely given to children. He arguably saved more lives than any other single person. And through his work, Hilleman...

What if someone asked you to get infected with the COVID-19 virus, deliberately, in order to speed up the development of a vaccine? Would you do it? Would you risk your life to save others? For months, dozens of companies have been racing to create coronavirus vaccines. Finally, three have done it. But according to the experts, we’re not out of the woods yet; we’ll need several vaccines to satisfy the global demand. One way to speed up the development process is a controversial technique...

Lies, liars, and lie catchers. This hour of Radiolab asks if it's possible for anyone to lead a life without deception.

In the days after the US Presidential election was called for Joe Biden, many supporters of Donald Trump are crying foul.  Voter fraud. And a key piece of evidence? A century-old quirk of math called Benford’s Law.  We at Radiolab know Benford’s Law well, and have covered it before.  In this political dispatch, Latif and Soren Sherlock their way through the precinct numbers to see if these claims hold up. Spoiler: they don’t. But the reason why is more interesting than you’d expect. This...

In the 1996 election, Bill Clinton had a problem. The women who came out in droves for him in ‘92, split their vote in the ‘94 midterms, handing over control of the House and the Senate to the Republican Party. As his team stared ahead at his re-election bid, they knew they had to win those women back. So, after a major polling effort to determine who exactly their undecided ladies were, Clinton turned his focus toward the most important swing vote in the election: the soccer moms.  The...

Baboon troops. We all know they’re hierarchical. There’s the big brutish alpha male who rules with a hairy iron fist, and then there’s everybody else. Which is what Meg Crofoot thought too, before she used GPS collars to track the movements of a troop of baboons for a whole month. What she and her team learned from this data gave them a whole new understanding of baboon troop dynamics, and, moment to moment, who really has the power.  This episode was reported and produced by Annie...

There’s plenty of speculation about what Donald Trump might do in the wake of the election. Would he dispute the results if he loses? Would he simply refuse to leave office, or even try to use the military to maintain control? Last summer, Rosa Brooks got together a team of experts and political operatives from both sides of the aisle to ask a slightly different question. Rather than arguing about whether he’d do those things, they dug into what exactly would happen if he did. Part war game...

With the recent passing of Ruth Bader Ginsburg, there's been a lot of debate about how much power the Supreme Court should really have. We think of the Supreme Court justices as all-powerful beings, issuing momentous rulings from on high. But they haven’t always been so, you know, supreme. On this episode, we go all the way back to the case that, in a lot of ways, started it all.  Support Radiolab by becoming a member today at Radiolab.org/donate.    

What are the police for? Producer B.A. Parker started wondering this back in June, as Black Lives Matter protests and calls to “defund the police” ramped up. The question led her to a wild story of a stabbing on a New York City subway train, and the realization that, according to the law, the police don’t always have to protect us. Producer Sarah Qari joins Parker to dig into the legal background, which takes her all the way up to the Supreme Court... and then all the way back down to on-duty...

Coronasomnia is a not-so-surprising side-effect of the global pandemic. More and more of us are having trouble falling asleep. We wanted to find a way to get inside that nighttime world, to see why people are awake and what they are thinking about. So what’d Radiolab decide to do?  Open up the phone lines and talk to you. We created an insomnia hotline and on this week’s experimental episode, we stayed up all night, taking hundreds of calls, spilling secrets, and at long last, watching the...
