In 1908, on a sunny, clear, quiet morning in Siberia, witnesses recall seeing a blinding light streak across the sky, and then … the earth shook, a forest was flattened, fish were thrown from streams, and roofs were blown off houses. The “Tunguska event,” as it came to be known, was one of the largest extraterrestrial impact events in Earth’s history. But what kind of impact—what exactly struck the earth in the middle of Siberia—is still up for debate. Producer Annie McEwen dives into one idea that suggests a culprit so mysterious, so powerful, so … tiny, you won’t believe your ears. And stranger still, it may be in you right now. Or, according to Senior Correspondent Molly Webster, it could be you.EPISODE CREDITS Reported by - Annie McEwen and Molly WebsterProduced by - Annie McEwen and Becca Bresslerwith help from - Matt KieltyOriginal music and sound design contributed by - Jeremy Bloom, Annie McEwen, Matt KieltyMixing by - Jeremy Bloomwith dialogue mixing by - Arianne WackFact-checking by - Diane Kellyand edited by - Alex Neason

Since the beginning of the space program, we’ve expected astronauts to be fully-abled athletic overachievers—one-part science geeks, two-part triathletes—a mix the writer Tom Wolfe called “the right stuff.”
But what if, this whole time, we’ve had it wrong?
In this episode from 2022, reporter Andrew Leland joins blind Linguistics Professor Sheri Wells-Jensen and a crew of 11 other disabled people. They embark on a mission to prove not just that they have what it takes to go to space, but that disability gives them an edge. On Mission AstroAccess, the crew members hop on an airplane to take a zero-gravity flight—the same NASA uses to train astronauts. With them, we learn that the challenges to making space accessible may not be the ones we thought. And Andrew, who is legally blind, confronts unexpected conclusions of his own.
By the way, Andrew’s new book is out. In The Country of the Blind: A Memoir at the End of Sight (https://zpr.io/nLZ8H), Andrew recounts his transition from sighted to blind. Suspended between anxiety and anticipation, he also begins to explore the many facets of blindness as a culture. It’s well worth a read.
Read the article by Sheri Wells-Jensen, published in The Scientific American in 2018. “The Case for Disabled Astronaut” (https://zpr.io/nLZ8H).

At a tree ring conference in the relatively treeless city of Tucson, Arizona, three scientists walk into a bar. The trio gets to talking, trying to explain a mysterious set of core samples from the Florida Keys. At some point, they come up with a harebrained idea: put the tree rings next to a seemingly unrelated dataset. Once they do, they notice something that no one has ever noticed before, a force of nature that helped shape modern human history and that is eerily similar to what’s happening on our planet right now. With help from pirates, astronomers and an 80-year-old bartender, this episode will change the way you look at the sun. (Warning: Do not look at the sun.)

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.
In this episode from 2019, Reporter Heather Radke and Producer Matt Kielty talk to two researchers who followed the butt from our ancient beginnings through millions of years of evolution, all the way to today, out to a valley in Arizona, where our butts are put to the ultimate test.
Special thanks to Michelle Legro.

Sad news for all of us: producer Rachael Cusick, who brought us soul-stirring stories rethinking grief and solitude, as well as colorful musings on airplane farts and belly flops and Blueberry Earths, is leaving the show. So we thought it perfect timing to sit down with her and revisit another brainchild of hers, The Cataclysm Sentence, a collection of advice for The End.
To explain: one day in 1961, the famous physicist Richard Feynman stepped in front of a Caltech lecture hall and posed this question to a group of undergraduate students: “If, in some cataclysm, all of scientific knowledge were to be destroyed, and only one sentence was passed on to the next generation of creatures, what statement would contain the most information in the fewest words?” Now, Feynman had an answer to his own question—a good one. But his question got the entire team at Radiolab wondering, what did his sentence leave out? So we posed Feynman’s cataclysm question to some of our favorite writers, artists, historians, futurists—all kinds of great thinkers. We asked them “What’s the one sentence you would want to pass on to the next generation that would contain the most information in the fewest words?” What came back was an explosive collage of what it means to be alive right here and now, and what we want to say before we go.

First, an evolutionary nightmare inside a single Covid patient. Then, the story of an ancient showdown between fungus and mammals that started when dinosaurs disappeared from the earth. Back then, the battle swung in our favor (spoiler alert!) and we’ve been hanging onto that win ever since. But one scientist suggests that the rise of this new infectious fungus indicates our edge is slipping, degree by increasing degree.
Given reporter Julia Longoria’s long love affair with the Supreme Court, it’s no surprise she’s become the new host of More Perfect (https://zpr.io/4R9fMg9gJ96k), a show all about how the Supreme Court got to be so… supreme. This week, we talk to Julia about her journey to the host seat, and we highlight an episode she produced for Radiolab in 2019 about a specific case: González v. Williams.
In 1903 the U.S. Supreme Court refused to say that Isabel González was a citizen of the United States. Then again, they said, she wasn’t exactly an immigrant either. And they said that the U.S. territory of Puerto Rico, Isabel’s home, was “foreign to the United States in a domestic sense.” Since then, the U.S. has cleared up at least some of the confusion about U.S. territories and the status of people born in them.
But, more than a hundred years later, there is still a U.S. territory that has been left in limbo: American Samoa. It is the only place on Earth that is U.S. soil, but people who are born there are not automatically U.S. citizens. When we visit American Samoa, we discover that there are some pretty surprising reasons why many American Samoans prefer it that way.

Love is in the air as we take to the skies this week, following a group of seagulls from the 1970s that rocked our understanding of what's natural in animals, and in us. Then, high above the banks of the Mississippi River, a nest holds the secret life of one of America's most patriotic creatures.
Shipworms. Hairy Chested Yeti Crabs. Parasitic Barnacles in the cloaca of Greenland Sharks. These are the types of creatures Sabrina Imbler, a columnist at Defector, likes to write about. The stranger, the better.
In this episode, Imbler discusses how they balance maintaining scientific rigor while also drawing inspiration and metaphor from the animal world. Then they read a stirring essay from their new book, How Far the Light Reaches: A Life in Ten Sea Creatures . It’s about the sand striker, one of the ocean’s most gruesome predators, and the various prey that surround it. In learning about the relationships between predator and prey lurking in the murky bottom, Imbler ends up unearthing new insights about predation in human society. The essay deals with sexual assault so listen with care.

Ross McNutt has a superpower: he can zoom in on everyday life, then rewind and fast-forward to solve crimes in a shutter-flash. But should he?
In 2004, when casualties in Iraq were rising due to roadside bombs, Ross McNutt and his team came up with an idea. With a small plane and a 44 megapixel camera, they figured out how to watch an entire city all at once, all day long. Whenever a bomb detonated, they could zoom into that spot and then, because this eye in the sky had been there all along, they could scroll back in time and see—literally see—who planted it. After the war, Ross McNutt retired from the Air Force, and brought this technology back home with him. Manoush Zomorodi and Alex Goldmark (from the podcast Note to Self) give us the lowdown on Ross’ unique brand of persistent surveillance, from Juarez, Mexico to Dayton, Ohio. Then, once we realize what we can do, we wonder whether we should.
