First aired back in 2009, this episode is all about one thing, or rather a collection of things. Whether you love 'em or hate 'em, chances are you rely on numbers every day of your life. Where do they come from, and what do they really do for us? This hour: stories of how numbers confuse us, connect us, and even reveal secrets about us.

As a lifeguard, a paramedic, and then an ER doctor, Blair Bigham found his calling: saving lives. But when he started to work in the ICU, he slowly realized that sometimes keeping people (and their hopes) alive just prolongs the suffering. He wrote a book arguing that a too-late death is just as bad as a too-early one, and that physicians and the public alike need to get better at accepting the inevitability of death sooner.  As the book hit the bestseller list, Blair’s own father got diagnosed with a deadly case of pancreatic cancer. Blair’s every impulse was in direct contradiction of the book he just wrote. What should he do? And how can any of us know when to stop fighting death and when to start making peace with it?Special thanks to Lucie Howell and Heather Haley.EPISODE CREDITS:  Reported by - Latif NasserProduced by - Simon Adlerwith help from - Alyssa Jeong PerryOriginal music and sound design contributed by - Simon Adlerwith mixing help from - Arianne WackFact-checking by - Natalie Middletonand edit

In this short episode that first aired in 2011, a neurologist issues a dare to a ragtime piano player and a famous conductor. When the two men face off in an fMRI machine, the challenge is so unimaginably difficult that one man instantly gives up. But the other achieves a musical feat that ought to be impossible. Reporter Jessica Benko went to Michigan to visit Bob Milne, one of the best ragtime piano players in the world, and a preternaturally talented musician. Usually, Bob sticks to playing piano for small groups of ragtime enthusiasts, but he recently caught the attention of Penn State neuroscientist Kerstin Bettermann, who had heard that Bob had a rare talent: He can play technically challenging pieces of music on demand while carrying on a conversation and cracking jokes. According to Kerstin, our brains just aren't wired for that. So she decided to investigate Bob's brain, and along the way she discovered that Bob has an even more amazing ability—one that we could hardly believe and science can't expla

Could puberty get any more awkward? Turns out, yes. Writer Patrick Burleigh started going through puberty as a toddler. He had pubic hair before he was two years old and a mustache by middle school. All of this was thanks to a rare genetic mutation that causes testotoxicosis, also known as precocious puberty. From the moment he was born, abnormally high levels of testosterone coursed through his body, just as it had in his father’s body, his grandfather’s body, and his great-grandfather’s body. On this week’s episode, Patrick’s premature coming of age story helps us understand just why puberty is so awkward for all of us, and whether and how it helps forge us into the adults we all become.

The definition of life is in flux, complexity is overrated, and humans are shrinking. Viruses are supposed to be sleek, pared-down, dead-eyed machines. But when one microbiologist stumbled upon a GIANT virus, hundreds of times bigger than any seen before, all that went out the window.  The discovery opened the door not only to a new cast of microscopic characters with names like Mimivirus, Mamavirus, and Megavirus, but also to basic questions: How did we miss these until now? Have they been around since the beginning? What if evolution could go … backwards? In this episode from 2015,  join former co-hosts Jad Abumrad and Robert Krulwich as they grill Radiolab regular Carl Zimmer on these paradoxical viruses – they’re so big that they can get their own viruses! - and what they can tell us about the nature of life.  Our newsletter comes out every Wednesday.

In this episode we introduce you to a part of our bodies that was invisible to Western scientists until about five years ago; it’s called "the interstitium," a vast network of fluid channels inside the tissues around our organs that scientists have just begun to see, name, and understand. Along the way we look at how new technologies rub up against long-standing beliefs, and how millions of scientists and doctors failed to see what was right in front (and inside!) of their noses. We also find out how mapping the anatomy of this hidden infrastructure may help solve one of the fundamental mysteries of cancer, and perhaps provide a bridge between ancient and modern medicine.Special thanks to Aaron Wickenden, Jessica Clark, Mara Zepeda, Darryl Holliday, Dr. Amy Chang, Kate Sassoon, Guy Huntley, John Jacobson, Scotty G, and the Village Zendo EPISODE CREDITS -  Reported by - Lulu Miller and Jenn BrandelProduced by - Matt Kieltywith help from - Ekedi Fausther-Keeyswith mixing help from - Arianne WackFact-checking by

Back when Robert was kid, he had a chance encounter with then President John F. Kennedy. The interaction began with a hello and ended with a handshake. And like many of us who have touched greatness, 14 year old Robert was left wondering if maybe some of Kennedy would stay with him. Back in 2017, when this episode first aired, Robert found himself still pondering that encounter and question. And so with the help of what was brand new science back then, and a helping hand from Neil Degrasse Tyson, he set out to satisfy this curiosity once and for all.EPISODE CREDITS:Produced by - Simon Adlerwith help from - Only Human: Amanda Aronczyk, Kenny Malone, Jillian Weinberger and Elaine Chen.

Back in February of 2022, anyone who knew anything thought the War in Ukraine would be over in a few weeks. Russia simply had more bodies to fight with and more steel to kill with.Fast-forward to today, however, and the war is anything but over. Ukraine has held and regained territory with shocking resilience. Stranger still, a small, cheap gadget that up until now was little more than a toy, has been central to their success.Today on Radiolab, we track the deployment of this weapon and wonder what happens when you have to look your enemy in the eye before you pull the trigger. Special thanks to Anna Kaliusna and her team for her footage from the frontline, Yulia Tarisuk for her help with all things Ukrainian language related. And Hanna Rose Shell for her helping us understand the history of camouflage.

While scouring the Sonoran Desert for objects left behind by migrants crossing into the United States, anthropologist Jason De León happened upon something he didn't expect to get left behind: a human arm, stripped of flesh. This macabre discovery sent him reeling, needing to know what exactly happened to the body, and how many migrants die that way in the wilderness. In researching border-crosser deaths in the Arizona desert, he noticed something surprising. Sometime in the late-1990s, the number of migrant deaths shot up dramatically and have stayed high since. Jason traced this increase to a Border Patrol policy still in effect, called “Prevention Through Deterrence.” First aired in 2018 and over three episodes, Radiolab investigates this policy, its surprising origins, and the people whose lives were changed forever because of it.

Originally aired in 2018, this episode features reporter Brena Farrell as 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 connection can tell us about ourselves in this cultural moment of anxiety and information-overload.

Summer 2023 was a pretty scary one for the planet. Global temperatures in June and July reached record highs. And over in the North Atlantic Sea, the water temperature spiked to off-the-chart levels. Some people figured that meant we were about to go over the edge, doomsday. In the face of this, Hank Green (a long time environmentalist and science educator behind SciShow, Crash Course, and more), took to social media to put things in context, to keep people focused on what we can do about climate change. In the process, he came across a couple studies that suggested a reduction in sulfurous smog from cargo ships may have accidentally warmed the waters. And while Hank saw a silver lining around those smog clouds, the story he told—about smog clouds and cooling waters and the problem of geoengineering—took us on a rollercoaster ride of hope and terror. Ultimately, we had to wrestle with the question of what we should be doing about climate change, or what we should even talk about.Special thanks to Dr. Colin Ca

Most of us would sacrifice one person to save five. It’s a pretty straightforward bit of moral math. But if we have to actually kill that person ourselves, the math gets fuzzy. That’s the lesson of the classic Trolley Problem, a moral puzzle that fried our brains in an episode we did almost 20 years ago, then updated again in 2017. Historically, the questions posed by The Trolley Problem are great for thought experimentation and conversations at a certain kind of cocktail party. Now, new technologies are forcing that moral quandary out of our philosophy departments and onto our streets. So today, we revisit the Trolley Problem and wonder how a two-ton hunk of speeding metal will make moral calculations about life and death that still baffle its creators.

In this episode from 2007, we take you on a tour of language, music, and the properties of sound. We look at what sound does to our bodies, our brains, our feelings… and we go back to the reason we at Radiolab tell you stories the way we do.  First, we look at Diana Deutsch’s work on language and music, and how certain languages seem to promote musicality in humans. Then we meet Psychologist Anne Fernald and listen to parents as they talk to their babies across languages and cultures. Last, we go to 1913 Paris and sneak into the premiere of Igor Stravinsky’s score of The Rite of Spring.  Check out Diana Deutsch's 'Audio Illusions' here (https://deutsch.ucsd.edu/psychology/pages.php?i=201).  Our newsletter comes out every Wednesday.

A couple years ago, our producer Annie McEwen listened to an audio documentary that, she said, “tore my heart wide open.” That episode , “Finn and the Bell,” (https://zpr.io/TDjwQuXFDSz6) by independent producer Erica Heilman (maker of the podcast  Rumble Strip), went on to win some of the biggest awards in audio (including a Peabody, https://zpr.io/tu4hwhKQ3TWN), and the rest of the staff finally got around to listening, and it tore our hearts wide open, too. It’s a story about a death, but as so many of the best stories about death tend to be, it ends up mainly being about life, in this case, the life of a small town in far northern Vermont, the town where Erica lives and makes her show. We think you’ll like it. You can find more than 200 other episodes of Rumble Strip here (https://zpr.io/dwGNnSFmAEFX). Erica’s episode about The Civic Standard (https://zpr.io/GJMP95QENFKq), the community organization started by Finn’s mom Tara Reese and her friend Rose Friedman, is here (https://zpr.io/9HL9mpZT4LTM).

When we think of China today, we think of a technological superpower. From Huawei and 5G to TikTok and viral social media, China is stride for stride with the United States in the world of computing. However, China’s technological renaissance almost didn’t happen. And for one very basic reason: The Chinese language, with its 70,000 plus characters, couldn’t fit on a keyboard.  Today, we tell the story of Professor Wang Yongmin, a hard headed computer programmer who solved this puzzle and laid the foundation for the China we know today.

Matthew Herrick was sitting on his stoop in Harlem when something weird happened. Then, it happened again. And again. It happened so many times that it became an absolute nightmare—a nightmare that haunted his life daily and flipped it completely upside down. What stood between Matthew and help were 26 little words. These 26 words, known as Section 230, are the core of an Internet law that coats the tech industry in Teflon. No matter what happens, who gets hurt, or what harm is done, tech companies can’t be held responsible for the things that happen on their platforms. Section 230 affects the lives of an untold number of people like Matthew, and makes the Internet a far more ominous place for all of us. But also, in a strange twist, it’s what keeps the whole thing up and running in the first place. Why do we have this law? And more importantly, why can’t we just delete it?
