Are Raccoons On The Road To Domestication?

Science Friday ·

2026/01/08

What does it mean to be a wild animal in a world dominated by humans? A recent study found that city-dwelling raccoons’ snouts are getting shorter—a sign of domestication. Another study on dark-eyed juncos living on a Los Angeles college campus found that their beaks changed shape during the COVID-19 lockdown, when there wasn’t as much food and trash on campus. Evolutionary biologist Pamela Yeh and animal domestication expert Raffaela Lesch join Host Flora Lichtman to discuss how wildlife is

Can The Rise In Solar Power Balance Out Clean Energy...

2026/01/05

Since President Trump returned to office, his administration has been aggressive in rolling back clean energy initiatives. Trump’s “big beautiful bill” ended tax credits for solar panels and electric vehicles. And the EPA is moving to cancel $7 billion dollars in federal grants that were intended to help low- and middle-income families install solar on their homes.But that isn’t the whole story. Texas, California, and other states are bringing so much solar and battery power online that in March,

What have we learned in recent years about black holes? Can entangled quantum particles really communicate faster than light? What’s the story behind Schrödinger’s Cat? And, in this weird liminal space between the holidays, what even IS time, really? Physicist Sean Carroll and Host Ira Flatow tackled those big questions and more at a recent event at WNYC’s Greene Space in New York City.

This year, comet 3I/Atlas broke into our solar system, but also the zeitgeist. This dirty snowball is a visitor from another solar system, and it’s only the third interstellar object we’ve ever spotted. And today, it's closer to us than ever before—just 170 million miles away.Astronomy experts Stefanie Milam and Hakeem Oluseyi join Host Flora Lichtman to dish about 3I/ATLAS and how it captured the spotlight in a way that maybe no other big hunk of rock ever has.Plus, the sun is setting on the ISS,

‘Fire Amoeba’ Likes It Hot, And A Faraway Lava Planet

2025/12/18

While on a sampling trip in California’s Lassen Volcanic National Park, researchers stopped to sample a rather boring stream on their hike to Boiling Springs Lake. But when they incubated that water sample back in the lab, they discovered an amoeba that could still move and divide at 145 F, a new record for a eukaryotic cell. Microbiologist Angela Oliverio joins Host Flora Lichtman to describe the “fire amoeba,” Incendiamoeba cascadensis.Plus, planetary scientist Johanna Teske takes us to exoplanet

A Startling Plan To Save Spotted Owls—From Barred Owls

Science Friday ·

2025/12/03

The spotted owl has been a conservation flashpoint for more than 30 years. While habitat loss has been their historic foe, their most recent threat comes from within the owl family tree: the barred owl. Barred owls have expanded into the Pacific Northwest and are now outcompeting spotted owls for food and habitat. The U.S. Fish and Wildlife Service has put forth a strategy that some experts say is the only way to save the spotted owl, and it could involve killing hundreds of thousands of barred

Can A Microbe Conservation Movement Take Off?

2025/12/02

A team of scientists is trying to jumpstart a global conservation movement, on par with efforts to save the rainforests or protect the oceans. But it might be even more ambitious because the target of their quest is invisible, everywhere, and mostly something we try to hand-sanitize away: microbes.So how do you conserve something that is everywhere and in everything? And why do microbes need protecting to begin with? Host Flora Lichtman digs into it with microbial ecologist Jack Gilbert, who is

How To Tap Into The Hidden Histories Of Rocks

When we try to commune with nature, many of us turn toward the living: a walk in the woods among swaying trees, chirping birds, blooming flowers.But earth scientist Anjana Khatwa says not to overlook the inanimate—don’t sleep on rocks. She joins Host Flora Lichtman to talk about her love for rocks beyond the scientific and her new book, The Whispers of Rock.Read an excerpt from The Whispers of Rock: The Stories That Stone Tells about Our World and Our Lives.Guest: Dr. Anjana Khatwa is a geologist

Fingernails And Indigestion At The 2025 Ig Nobel Prizes

Each year, the Ig Nobel Prizes recognize scientific research that first makes you laugh, then makes you think. For instance, researchers who investigated the pizza preferences of lizards on the island of Togo. Or a man who kept track of his fingernail growth for 35 years.As is Thanksgiving tradition, we’re sharing highlights from this year’s Ig Nobels on Science Friday.

Why Is Working Out Good For Your Mental Health?

A good workout can make you feel triumphant. And even if that isn’t your relationship with exercise, you’ve probably heard that working out can lift your mood, fight depression, and make you more resilient when life knocks back. But why exactly does exercise improve mental health? Is it all about those endorphins? Does the type or duration of a workout matter if you’re looking for a mental wellness boost?To help answer those questions and more, Host Flora Lichtman talks with Eduardo Esteban

Have you ever gotten to the end of, say, a jar of peanut butter and wondered if it should go in trash or recycling? If it’s worth rinsing out? And where will it actually end up?Journalist Alexander Clapp had those same questions, and went to great lengths to answer them—visiting five continents to chronicle how our trash travels. Along the way, he discovered a multibillion-dollar trash trade run by shady waste brokers, and a global industry powered by slimy spoons, crinkled plastic bags, and all the

Can Animal Super-Agers Teach Us Their Secrets?

2025/11/19

Some animals have a very different relationship to aging than we do: They don’t get cancer, they never go through menopause, and they live absurdly long lives. For instance, one bat species can live for more than 40 years, which may not sound like very long but that’s about nine times longer than expected based on its size. For comparison, if we aged on that scale, we’d live for hundreds of years. These bats aren’t the only animal super-agers—there’s a whole menagerie of them.So what’s their secret

How Alphafold Has Changed Biology Research, 5 Years On

2025/11/18

Proteins are crucial for life. They're made of amino acids that “fold” into millions of different shapes. And depending on their structure, they do radically different things in our cells. For a long time, predicting those shapes for research was considered a grand biological challenge.But in 2020, Google’s AI lab DeepMind released Alphafold, a tool that was able to accurately predict many of the structures necessary for understanding biological mechanisms in a matter of minutes. In 2024, the

If you’ve heard the hammering of a woodpecker in the woods, you might have wondered how the birds can be so forceful. What does it take to whack your head against a tree repeatedly, hard enough to drill a hole? A team of researchers wondered that too and set out to investigate, by putting tiny muscle monitors on eight downy woodpeckers and recording them with high-speed video as they pecked away in the lab.Integrative organismal biologist Nick Antonson, co-author of a report on the work, joins Host

Memories Change. But Can We Change Them On Purpose?

Our memories make us who we are—just ask Barbra Streisand. But despite the lyrics in many popular songs, memories aren’t frozen in time. When we call them up, the details shift and change. And neuroscience research shows that we might be able to take that a step further—to manipulate our memories and even implant false ones.Neuroscientist Steve Ramirez joins Host Ira Flatow to explain how memory manipulation could revolutionize the way we treat brain disorders.

Bearded vultures build giant, elaborate nests that are passed down from generation to generation. And according to a new study, some of these scavengers have collected bits and bobs of human history over the course of centuries. Scientists picked apart 12 vulture nests preserved in Spain and discovered a museum collection’s worth of objects, including a woven sandal that could be more than 700 years old.
