Radiolab

It began with a tweet: “EVERY DAY IS IGNAZ SEMMELWEIS DAY.” Carl Zimmer — tweet author, acclaimed science writer and friend of the show — tells the story of a mysterious, deadly illness that struck 19th century Vienna, and the ill-fated hero who uncovered its cure … and gave us our best weapon (so far) against the current global pandemic. This episode was reported and produced with help from Bethel Habte and Latif Nasser. Support Radiolab today at Radiolab.org/donate. 

In a recent Radiolab group huddle, with coronavirus unraveling around us, the team found themselves grappling with all the numbers connected to COVID-19. Our new found 6 foot bubbles of personal space. Three percent mortality rate (or 1, or 2, or 4). 7,000 cases (now, much much more). So in the wake of that meeting, we reflect on the onslaught of numbers - what they reveal, and what they hide.  Support Radiolab today at Radiolab.org/donate. 

The Other Latif Radiolab’s Latif Nasser always believed his name was unique, singular, completely his own. Until one day when he makes a bizarre and shocking discovery. He shares his name with another man: Abdul Latif Nasser, detainee 244 at Guantanamo Bay. The U.S. government paints a terrifying picture of The Other Latif as Al-Qaeda’s top explosives expert, and one of the most important advisors to Osama bin Laden. Nasser’s lawyer claims that he was at the wrong place at the wrong time, and that he was never even in Al-Qaeda. This clash leads Radiolab’s Latif into a years-long investigation, picking apart evidence, attempting to separate fact from fiction, and trying to uncover what this man actually did or didn’t do. Along the way, Radiolab’s Latif reflects on American values and his own religious past, and wonders how his namesake, a fellow nerdy, suburban Muslim kid, may have gone down such a strikingly different path.   Episode 6: Washington, D.C.

On the occasion of his retirement as cohost of Radiolab, Robert sat down with Jad to reflect on his long and storied career in radio and television, and their work together over the past decade and a half. And we pay tribute to Robert, inspired by a peculiar tradition of his. This episode was produced by Matt Kielty. Sound design & mix by Jeremy Bloom. Support Radiolab today at Radiolab.org/donate. 

Right now, at this very moment, all across the planet, there are 7.6 billion human beings eating, breathing, sleeping, brushing their teeth, walking their dogs, drinking coffee, walking down the street or running onto the subway or hopping in their car, maybe reading a summary of a podcast they’re about to hit play on … and the number is only going up. Everyday 386,000 babies are born (16,000 an hour). We’re adding a billion new people every 12 years. So here’s a question you’ve probably never thought about: Are there more people alive right now than have ever lived on the planet in history? Do the living outnumber the dead? Robert got obsessed with this odd question, and in this episode we bring you the answer. Or, well, answers. This episode was reported by Robert Krulwich and produced by Annie McEwen and Pat Walters, with help from Neel Dhanesha. Fact-checking by Michelle Harris. Music and mixing by Jeremy Bloom.

This hour we pull apart one sentence, written in the hours after September 11th, 2001, 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.

This is a story about your butt. It’s a story about how you got your butt, why you have your butt, and how your butt might be one of the most important and essential things for you being you, for being human.  Today, reporters Heather Radke and Matt Kielty talk to two researchers who followed the butt from our ancient beginnings, through millions of years of evolution, and all the way to today, out to a valley in Arizona, where our butts are put to the ultimate test.   This episode was reported by Heather Radke and Matt Kielty and was produced by Matt Kielty, Rachael Cusick and Simon Adler.

Here's a simple question: When an animal disappears in the winter, where does it go? Oddly enough, this question completely stumped European scientists for thousands of years. And even today, the more we learn about the comings and goings of the animals, the deeper the mystery seems to get. We visit a Bavarian farm with an 11 year old, follow warblers and wildebeests around the world, and get a totally new kind of view of the pulsing flow of animals across the globe.   This episode was reported by Robert Krulwich and Jackson Roach and produced by Pat Walters, Matt Kielty, and Jackson Roach. Mix & original music by Jeremy Bloom.   Special thanks to Allison Shaw, David Barrie, Auriel Fournier, and Moritz Matschke.

From a piece of the Wright brother's plane to a child’s sugar egg, today: Things! Important things, little things, personal things, things you can hold and things that can take hold of you. This hour, we investigate the objects around us, their power to move us, and whether it's better to look back or move on, hold on tight or just let go.

Deep fake videos have the potential to make it impossible to sort fact from fiction. And some have argued that this blackhole of doubt will eventually send truth itself into a death spiral. But a series of recent events in the small African nation of Gabon suggest it's already happening.  Today, we follow a ragtag group of freedom fighters as they troll Gabon’s president - Ali Bongo - from afar. Using tweets, videos and the uncertainty they can carry, these insurgents test the limits of using truth to create political change and, confusingly, force us to ask: Can fake news be used for good?

Today on Radiolab, we're bringing you the fourth episode of Jad's special series, Dolly Parton's America. In this episode, Jad goes back up the mountain to visit Dolly’s actual Tennessee mountain home, where she tells stories about her first trips out of the holler. Back on the mountaintop, standing under the rain by the Little Pigeon River, the trip triggers memories of Jad’s first visit to his father's childhood home, and opens the gateway to dizzying stories of music and migration.

Coming off our adventures with Square Dancing, and Jad's dive into the world of Dolly Parton, we look back at one our favorites. About a decade ago, we found out that American country music is surprising popular in places like Zimbabwe, Thailand, and South Africa. Aaron Fox, an anthropologist of music at Columbia University, tells us that quite simply, country music tells a story that a lot of us get. Then, intrepid international reporter Gregory Warner takes us along on one of his very first forays into another country, where he discovers an unexpected taste of home.

People have been doing the square dance since before the Declaration of Independence. But does that mean it should be THE American folk dance? That question took us on a journey from Appalachian front porches, to dance classes across our nation, to the halls of Congress, and finally a Kansas City convention center. And along the way, we uncovered a secret history of square dancing that made us see how much of our national identity we could stuff into that square, and what it means for a dance to be of the people, by the people, and for the people.  Special thanks to Jim Mayo, Claude Fowler, Paul Gifford, Jim Maczko, Jim Davis, Paul Moore, Jack Pladdys, Mary Jane Wegener, Kinsey Brooke and Connie Keener.  This episode was reported by Tracie Hunte and produced by Annie McEwen, Tracie Hunte, and Matt Kielty. Mix by Jeremy Bloom.
