Today we have a story about the sometimes obvious but sometimes sneaky effects of the way that we humans rearrange the elemental stuff around us. Reporter Avir Mitra and science journalist Lydia Denworth bring us a story about how one man’s relentless pursuit of a deep truth about the Earth led to an obsession that really changed the very air we breathe. This episode was reported by Avir Mitra, and produced by Matt Kielty, Becca Bressler, Rachael Cusick, and Maria Paz Gutiérrez. Special thanks to Cliff Davidson, Paul M.

It has now been 20 years since September 11th, 2001. So we’re bringing you a Peabody Award-winning story from our archives about one sentence, written in the hours after the attacks, that has led to the longest war in U.S. history. We examine how just 60 words of legal language have blurred the line between war and peace. In the hours after the attacks of Sept. 11, 2001, a lawyer sat down in front of a computer and started writing a legal justification for taking action against those responsible. The language that he drafted and that President George W. Bush signed into law - called the Authorization for Use of Military Force (AUMF) -  has at its heart one single sentence, 60 words long. Over the last decade, those 60 words have become the legal foundation for the "war on terror." In this collaboration with BuzzFeed, reporter Gregory Johnsen tells us the story of how this has come to be one of the most important, confusing, troubling sentences of the last two decades. We go into the meetings that took place i

Multiple sclerosis, lupus, rheumatoid arthritis, even psoriasis — these are diseases in which the body begins to attack itself, and they all have one thing in common: they affect women more than men. Most autoimmune disorders do. And not just by a little bit, often by a lot; in some cases, as much as sixteen times more. But why? On today’s episode, we talk to scientists trying to answer that question. We go back 100 million years, to when our placenta first evolved and consider how it might have shaped our immune system. We dive deep into the genome, to stare at one of the most famous chromosomes: the X. And we also try to unravel a mystery — why is it that for some females, autoimmune disorders seemingly disappear during pregnancy? This episode was reported by Molly Webster, and produced by Sindhu Gnanasambandan and Molly Webster. The Gonads theme song was written, performed, and produced by Majel Connery and Alex Overington.  Looking for something else to listen to? We suggest pairing “The Unsilencing” with

We all think we know the story of pregnancy. Sperm meets egg, followed by nine months of nurturing, nesting, and quiet incubation. But 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 we take you on a journey through the 270-day life of this weird, squishy, gelatinous orb, and discover that it is so much more than an organ. It’s a foreign invader. A piece of meat. A friend and parent. And it’s perhaps the most essential piece in the survival of our kind. This episode was reported by Heather Radke and Becca Bressler, and produced by Becca Bressler and Pat Walters, with help from Matt Kielty and Maria Paz Gutierrez.

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. First aired in 2018, Dutee and the story of female athletes in sport are back in the spotlight this week, at the Tokyo Olympics. Join us for an update on Dutee’s second Olympic games, and the continued role testosterone has in shaping who is on the track, and who is off.  This story was originally released as part of Gonads, a six-part series on the parts of us that make more of us. It is a companion piece to Gonads, episode 5: Dana. This update was reported by Molly Webster, with reporting and producing by Sarah Qari. "Dutee" was reported by Molly Webster, with co-reporting and translation by Sarah Qari. It was produced by Pat Walters, wi

If you’ve ever lost someone, or watched a medical drama in the last 15 years, you’ve probably heard of The Five Stages of Grief. They’re sort of the world’s worst consolation prize for loss. But last year, we began wondering… Where did these stages come from in the first place? Turns out, Elisabeth Kübler-Ross. But the story is much, much more complicated than that. Those stages of grieving? They actually started as stages of dying. After learning that, producer Rachael Cusick tumbled into a year-long journey through the life and work of the incredibly complicated and misunderstood woman who single-handedly changed the way all of us face dying, and the way we deal with being left behind. Special Note: Our friends over at Death Sex and Money have put together a very special companion to this story, featuring Rachael talking about this story with her grandmother.  Check it out here. This episode was reported and produced by Rachael Cusick, with production help from Carin Leong. This story wouldn’t have been pos

In the past few weeks, most people have probably seen Britney Spears' name or face everywhere. When she stood in front of a judge (virtually) and protested the conservatorship she's been living under for the past 13 years, one harrowing detail in particular stood out. She told the judge, "I was told right now in the conservatorship, I'm not able to get married or have a baby." Today, we look back at an old episode where we explore why it is that hundreds of thousands of people can have their reproductive rights denied...and spoiler: it goes back to Darwin. When a law student named Mark Bold came across a Supreme Court decision from the 1920s that allowed for the forced sterilization of people deemed “unfit,” he was shocked to discover that it had never been overturned. His law professors told him the case, Buck v Bell, was nothing to worry about, that the ruling was in a kind of legal limbo and could never be used against people. But he didn’t buy it. In this episode we follow Mark on a journey to one of the

We’ve just barely made it to the other side of a year that took our collective breaths away. So more than ever we felt that this was the time to go deep on life’s rhythmic dance partner. Today we huff and we puff through a whole stack of stories about breath. We talk to scientists, musicians, activists, and breath mint experts, and try to climb into the very center of this thing we all do, are all doing right now, and now, and now.  This episode was reported and produced by Annie McEwen, Matt Kielty, and Molly Webster.

Back in 2014, Corey Knowlton paid $350,000 for a hunting trip to Namibia to shoot and kill an endangered species.  He’s a professional hunter, who guides hunts all around the world, so going to Africa would be nothing new.  The target on the other hand would be. And so too, he quickly found, would be the attention.  This episode, producer Simon Adler follows Corey as he dodges death threats and prepares to pull the trigger.  Along the way we stop to talk with Namibian hunters and government officials, American activists, and someone who's been here before - Kenya’s former Director of Wildlife, Richard Leakey.   All the while, we try to uncover what conservation really means in the 21st century. Reported & produced by Simon Adler with production help from Matthew Kielty.

In this episode, we break the thermometer watch the mercury spill out as we discover temperature is far stranger than it seems.
