The Age of Aquaticus

For years, scientists thought nothing could live above 73℃/163℉. At that temperature, everything boiled to death. But scientists Tom Brock and Hudson Freeze weren’t convinced. What began as their simple quest to trawl for life in some of the hottest natural springs on Earth would, decades later, change the trajectory of biological science forever, saving millions of lives—possibly even yours. This seismic, totally unpredictable discovery, was funded by the U.S. government. This week, as the Trump administration slashes scientific research budgets en masse, we tell one story, a parable about the unforeseeable miracles that basic research can yield. After that, a familiar voice raises some essential questions: what are we risking with these cuts? And can we recover? Special thanks to Joanne Padrón Carney, Erin Heath, Valeria Sabate, Gwendolyn Bogard, Meredith Asbury and Megan Cantwell at AAAS. Thank you as well to Gregor Čavlović and Derek Muller and the rest of the Veritasium team.

Ghosts in the Green Machine

In honor of our Earth, on her day, we have two stories about the overlooked, ignored, and neglected parts of nature. In the first half, we learn about an epic battle that is raging across the globe every day, every moment. It's happening in the ocean, and your very life depends on it. In the second half, we make an earnest, possibly foolhardy, attempt to figure out the dollar value of the work of bats and bees as we try to keep our careful calculations from falling apart in the face of the realities of life, and love, and loss.

Signal Hill: Caterpillar Roadshow

A couple years ago, an entomologist named Martha Weiss got a letter from a little boy in Japan saying he wanted to replicate a famous study of hers. We covered that original study on Radiolab more than a decade ago in an episode called Goo and You – check it out here – and in addition to revealing some fascinating secrets of insect life, it also raises big questions about memory, permanence and transformation. The letter Martha received about building on this study set in motion a series of spectacular events that advance her original science and show how science works when a 12-year-old boy is the one doing it. Martha’s daughter, reporter Annie Rosenthal, captured all of it and turned it into a beautiful audio story called “Caterpillar Roadshow.” It was originally published in a brand new independent audio magazine called Signal Hill, which happens to have been created in part by two former Radiolab interns (Liza Yeager and Jackson Roach, both of whom worked on this piece), and we loved it, so we’re presenting an excerpt for you here. Special thanks to Annie Rosenthal, Liza Yeager, Jackson Roach, Leo Wong, Omar Etman, the whole team at Signal Hill, Carlos Morales, John Lill, Marfa Public Radio and Emma Garschagen.

Killer Empathy

In an episode first aired in 2012, Lulu Miller introduces us to Jeff Lockwood, a professor at the University of Wyoming, who spent a part of his career studying a particularly ferocious set of insects: Gryllacrididae. Or, as Jeff describes them, "crickets on steroids." They have crushingly strong, serrated jaws, and they launch all-out attacks on anyone who gets in their way--whether it's another cricket, or the guy trying to take them out of their cages. In order to work with the gryllacridids, Jeff had to figure out how to out-maneuver them. And as he devised ways to keep from getting slashed and bitten, he felt like he was getting to know them. Maybe they weren't just mindless brutes ... but their own creatures, each with their own sense of self. And that got him wondering: what could their fierceness tell him about the nature of violence? How well could he understand the minds of these insects, and what drove them to be so bloody? That's when the alarm bells went off. Jeff would picture his mentor, Dr. LaFage, lecturing him back in college--warning him not to slip into a muddled, empathic mood ... not to let his emotions sideswipe his objectivity. And that would usually do the trick--Jeff would think of LaFage, and rein himself back in. But then one night, something happened that gave Dr. LaFage's advice a terrible new kind of significance. Tamra Carboni tells us this part of the story, and challenges Jeff's belief that there's a way to understand it.

Malthusian Swerve

Earth can sustain life for another 100 million years, but can we?In this episode, we partnered with the team at Planet Money to take stock of the essential raw materials that enable us to live as we do here on Earth—everything from sand to copper to oil— and tally up how much we have left. Are we living with reckless abandon? And if so, is there even a way to stop? This week, we bring you a conversation that’s equal parts terrifying and fascinating, featuring bird poop, daredevil drivers, and some staggering back-of-the-envelope math.

Everybody's Got One

We all think we know the story of pregnancy. Sperm meets egg, followed by nine months of nurturing, nesting, and quiet incubation. 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, which we originally released in 2021, 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. Special thanks to Diana Bianchi, Julia Katz, Sam Behjati, Celia Bardwell-Jones, Mathilde Cohen, Hannah Ingraham, Pip Lipkin, and Molly Fassler.

Growth

It’s easy to take growth for granted, for it to seem expected, inevitable even. Every person starts out as a baby and grows up. Plants grow from seeds into food. The economy grows. That stack of mail on your table grows. But why does anything grow the way that it does? In this hour, we go from the Alaska State Fair, to a kitchen in Berkeley, to the deep sea, to ancient India, to South Korea, and lots of places in between, to investigate this question, and uncover the many forces that drive growth, sometimes wondrous, sometimes terrifying, and sometimes surprisingly, unnervingly fragile.

More Perfect: Sex Appeal

In 2017 our sister show, More Perfect aired an episode all about RBG, In September of 2020, we lost Supreme Court Justice Ruth Bader Ginsburg to the annals of history. She was 87. Given the atmosphere around reproductive rights, gender and law, we decided to re-air this More Perfect episode dedicated to one of her cases. Because it offers a unique portrait of how one person can make change in the world. This is the story of how Ginsburg, as a young lawyer at the ACLU, convinced an all-male Supreme Court to take discrimination against women seriously - using a case on discrimination against men. Special thanks to Stephen Wiesenfeld, Alison Keith, and Bob Darcy. Supreme Court archival audio comes from Oyez®, a free law project in collaboration with the Legal Information Institute at Cornell.

Welcome, nature lovers, to the home of the Terrestrials podcast and family-friendly Radiolab episodes about nature. Every other week, host Lulu Miller will take you on a nature walk to encounter a plant or animal behaving in ways that will surprise you. Squirrels that can regrow their brains, octopuses that can outsmart their human captors, honeybees that can predict the future. You don’t have to be a kid to listen, just someone who likes to see the world anew. You’ll hear a range of nature stories on this podcast. Sometimes these will be brand new Terrestrials episodes, full of original songs (by “The Songbud” Alan Goffinski) that tell a fantastical-sounding story about nature that is 100% true. Sometimes these will be our very best, shiniest, furriest, leafiest Radiolab episodes about animals or plants or nature. The stories that drop here will always be family-friendly and safe for kids. They will always be sound-rich and full of the vivid, gripping storytelling you’ve come to expect from Radiolab. They will always transport you to the beyond-human world: into the depths of the ocean, into jungles, prairies, forests, space, snow, wildflower fields and beyond. Sometimes we’ll encounter something so wild we just have to break out into song about it! Don’t worry, good voices not required. Join us on this adventure!

EDUCATION FOR KIDS
In this intensely divided moment, one of the few things everyone still seems to agree on is Dolly Parton—but why? That simple question leads to a deeply personal, historical, and musical rethinking of one of America’s great icons. Join us for a 9-episode journey into the Dollyverse. Hosted by Jad Abumrad. Produced and reported by Shima Oliaee. Dolly Parton’s America is a production from OSM Audio and WNYC Studios.

MUSIC HISTORY
The episodes from this mini-series can be accessed in the Radiolab podcast feed and radiolab.org for free, or access the ad-free versions here when you become a Radiolab+ subscriber. Before there was the podcast and the smartphone, there was the cassette tape and the Walkman — two devices that although not considered much today, were revolutionary. They were recordable, rewritable, spliceable, compact, mobile. For the first time they allowed you to move through the world and listen to a voice speaking only to you. These cassette tapes brought us together, pulled us apart and forever changed how we say those three simple words, "I love you." In five episodes from around the world, Mixtape explores the impact the cassette had and continues to have today.

SOCIETY & CULTURE
Radiolab reporter Latif Nasser always believed his name was uniquely his own. Until he makes a shocking discovery that he shares his name with another man: 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 an advisor 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, 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, traveled such a strikingly different path.

This podcast stands out as pretty much constantly astounding. As someone who writes about science for a living, the 'scientific' concepts here are rendered in an enviably fascinating and pretty much idiot-proof way. It's a testament to the skills of the hosts in their use of the audio format that they can cruise through really complex stuff and give the ordinary listener entertainment and learning in a single scoop. This is the best. Now if they would only get season one on itunes....
One of my fave podcasts, hands down

RadioLab has fallen off the train in terms of quality. Most of the best episodes are reruns. The newest content has just been mush for a year or so. Sad to see an old friend dying chasing dollars.
