One morning, Oliver Sipple went out for a walk. A couple hours later, to his own surprise, he saved the life of the President of the United States. In a story we reported back in 2017, we explain how in the days that followed, Sipple’s split-second act of heroism turned into a ra

A couple summers ago, Radiolab reporter Alex Neason got out of the shower and almost stepped on her worst nightmare: an American Cockroach. It was flipped onto its back, struggling, and for a split second, Alex swears she felt the spiny tickle of its legs on the underside of her

This episode makes three earnest, possibly foolhardy, attempts to put a price on the priceless. We figure out the dollar value for an accidental death, another day of life, and the work of bats and bees as we try to keep our careful calculations from falling apart in the face of

For most of human history, people went about their daily lives with a worm or two (or fifty) in their guts. Only in the past century, with pharmaceuticals and sanitation practices, have we made significant strides towards deworming the whole of humanity. And that’s typically been

With all of the black-and-white moralizing in our world today, we decided to bring back an old show from 2011 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

There’s something rotten in the cows of Denmark. And Minnesota. And Wisconsin. And Idaho. What could cause a previously thriving herd of majestic dairy cattle to stop drinking water and start drinking … urine? A Danish farmer calls a special investigator, who takes one look at hi

This week, in an episode we first aired in 2022, we flip the Disney story of life on its head thanks to a barrel of seawater, a 1970s era computer, and underwater geysers. It’s the chaos of life. Latif, Lulu, and our Senior Producer Matt Kielty were all sitting on their own littl

Doctor and special correspondent Avir Mitra takes Executive Editor Soren Wheeler, plus a live studio audience, on a journey from the operating room to inside the body to the farm to the sewers and back again—searching for answers to an alarming threat to humanity’s existence as w

A strange brew that's hard to resist, even for a modern day microbe. In the war on devilish microbes, our weapons are starting to fail us. The antibiotics we once wielded like miraculous flaming swords seem more like lukewarm butter knives. But in this episode, originally releas
