How Math Helps Us Map The World

Science Friday ·

2025/10/16

It’s easy to take maps for granted. After all, most of us have a pretty good map in our pockets at all times, ready to show us how to get anywhere on the globe. But to make a map useful, you have to decide what to keep in and what to leave out—and, most importantly, which mathematical equations to use. Beyond navigating from point A to point B, math and maps come together for a wide variety of things, like working out the most efficient route to deliver packages, calculating the depth of the ocean

The Science Of Replacing Body Parts, From Hair To Hearts

Science Friday ·

2025/10/15

It seems like every week, there’s a new headline about some kind of sci-fi-esque organ transplant. Think eyeballs, 3D-printed kidneys, pig hearts.In her new book, Replaceable You: Adventures in Human Anatomy, science writer Mary Roach chronicles the effort to fabricate human body parts—and where that effort sometimes breaks down. Host Flora Lichtman speaks with Roach about everything from hair transplants to 3D-printed hearts, and why our anatomy is so hard to replicate in the first place.Guest:

Remember “The Biggest Loser”—the show where people tried to lose as much weight as quickly as possible for a big cash prize? The premise of the show was that weight loss was about willpower: With enough discipline, anyone can have the body they want.The show’s approach was problematic, but how does its attitude toward weight loss match our current understanding of health and metabolism? The authors of the book Food Intelligence, nutrition scientist Kevin Hall, who studied “Biggest Loser” contestants

100 Years Later, Quantum Science Is Still Weird

Science Friday ·

2025/10/13

In July 1925, physicist Werner Heisenberg wrote a letter to Wolfgang Pauli sharing his new ideas about what would eventually become known as quantum theory. A hundred years later, that theory has been expanded into a field of science that explains aspects of chemical behavior, has become the basis of a new type of computing, and more. But it’s still really weird, and often counterintuitive. Physicist Chad Orzel joins Host Ira Flatow to celebrate 100 years of quantum science, and separate quantum

This year’s Nobel Prize in Physiology or Medicine went to three people whose combined discoveries outlined the role of the peripheral immune system—how the immune system knows to attack just foreign invaders and not its own tissues and organs. But when the phone rang for Shimone Sakaguchi, Mary E. Brunkow, and Fred Ramsdell, only two of them picked up.Host Ira Flatow talks with Nobel Prize winner Fred Ramsdell, co-founder and scientific advisor at Sonoma Biotherapeutics.Plus, Ira talks with

The Klamath River, which runs from southern Oregon to California, used to be a top salmon run. But after a series of hydroelectric dams was installed along the river around 100 years ago, salmon populations tanked.This is the prologue to a remarkable story of a coalition that fought to restore the river. Led by members of the Yurok Nation, who’ve lived along the river for millennia, a group of lawyers, biologists, and activists successfully lobbied for the removal of the dams. The fourth and final

Archeologists in movies have a reputation for being hands-on, like Indiana Jones unearthing hidden treasure, or Lara Croft running through a temple. Archeology in real life tends to be a bit more sedentary. But some archeologists are committed to getting their hands dirty—even recreating the stinky, slimy, and sometimes tasty parts of ancient life.Science writer Sam Kean enmeshed himself in the world of experimental archaeology for his new book Dinner with King Tut: How Rogue Archaeologists are

Moth Survival Strategies And A Rodent Thumbnail Mystery

2025/10/07

If you’re a moth trying to stay uneaten, there are competing strategies. Some moths rely on camouflage, trying to blend in. Other moths take the opposite approach: They’re bold and bright, with colors that say “don’t eat me, I’m poison.” Biologist Iliana Medina joins Host Flora Lichtman to describe a study that placed some 15,000 origami moths in forests around the world to investigate which strategy might work best.

Jane Goodall, renowned primatologist, conservationist, and humanitarian, died on October 1 at the age of 91. Goodall was born in London in 1934, and her curiosity about the natural world led her to the forests of Gombe, Tanzania, where she made groundbreaking observations of chimpanzee behavior, including tool use. Her research challenged the accepted scientific perceptions of our closest relatives.Host Ira Flatow shares his memories of Dr. Goodall, including an interview from 2002 in which she

What Do We Know About SSRI Antidepressant Withdrawal?

2025/10/02

Roughly 1 in 10 Americans take antidepressants. The most common type is SSRIs, or selective serotonin re-uptake inhibitors, like Prozac, Lexapro, and Zoloft. But what happens when you stop taking them? Studies don’t point to a single conclusion, and there’s ongoing debate among physicians and patients about the severity and significance of SSRI withdrawal symptoms. The discourse reached a fever pitch when Health Secretary Robert F. Kennedy Jr. compared SSRI withdrawal to heroin withdrawal in

The tropical waters of Sri Lanka, an island off the coast of India, are home to a population of blue whales unlike any other. These whales stay put, while every other known population migrates. That discovery was made by budding scientist Asha de Vos more than 20 years ago—it made a splash, and so did she. She later became the first Sri Lankan to earn a PhD studying marine mammals, charting a new scientific path in her country.Host Flora Lichtman talks with de Vos about her path into science, what

Robots are just about everywhere these days: circling the grocery store, cleaning the floor at the airport, making deliveries. Not to mention the robots on the assembly lines in factories. But how far are we from having a human-like robot at home? For example, a robot housekeeper like Rosie from “The Jetsons.” She didn’t just cook and clean, she bantered and bonded with the Jetsons.

Sift through your memories and excavate an image of a fossil. Maybe you’re picturing dinosaur bones, the imprint of an ammonite, or the fronds of a fern etched into stone. But there’s a whole other category of fossilized remains that can tell us about life way before T. rexes, or even twigs, existed on this planet. That’s fossilized evidence of microbes.Microbiologist Paula Welander uses these ancient remains to understand how life began on Earth. She joined Host Flora Lichtman for our live show at

Nigeria is home to 100 known species of bats—about a third of Africa’s bat species—but scientists don’t know much about them. Ecologists Iroro Tanshi and Benneth Obitte, collaborators and life partners, are trying to change that. In addition to studying and protecting the bats of their homeland, they’re also working to raise up a whole network of bat scientists across West Africa.

How Conservation Efforts Brought Rare Birds Back From...

2025/09/19

The overall state of birds can seem rather grim. Almost a third of North American bird species are in decline, and in the last five decades, more than 100 species have lost over half of their populations. This is primarily due to lack of food—fewer insects to eat—and habitat loss, like the development of grasslands. But there’s a bright spot: Some birds that were once rare are now abundant, like the merlin, sandhill crane, and pileated woodpecker. Host Ira Flatow talks with biologist Tom Langen, who
