Science Friday and WNYC Studios

Covering the outer reaches of space to the tiniest microbes in our bodies, Science Friday is the source for entertaining and educational stories about science, technology, and other cool stuff.

Science Friday

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. Carroll’s book The Biggest Ideas in the Universe: Space, Time, and Motion is the SciFri Book Club pick for December. 

Guest: Dr. Sean Carroll is the Homewood Professor of Natural Philosophy at Johns Hopkins University in Baltimore.

Tangling With Entanglement And Other Big Ideas In Physics

Health psychologist Dr. Kari Leibowitz traveled to some of the coldest, darkest places on earth to learn how people there don’t just survive, but thrive in winter. She says that one of the key ingredients is adopting a positive wintertime mindset by focusing on and celebrating the good parts of winter.

In a conversation from January, Flora Lichtman talks with Dr. Kari Leibowitz, author of How to Winter: Harness Your Mindset to Thrive on Cold, Dark, or Difficult Days, about saunas, cold plunges, candles, and other small ways to make winter a season to look forward to rather than dread. Plus, she responds to some of our audience’s own tips to make the season enjoyable.

Guest: Dr. Kari Leibowitz is a health psychologist and author of How to Winter: Harness Your Mindset to Thrive on Cold, Dark, or Difficult Days. She’s based in Amsterdam, The Netherlands.

The Science Of Thriving In Winter—By Embracing It

Imagine sitting at home and then all of a sudden you hear a men’s choir belting out “The Star Spangled Banner.” You check your phone, computer, radio. Nothing’s playing. You look outside, no one’s there. That’s what happened to neurologist Bruce Dobkin after he received a cochlear implant. He set out to learn everything he could about the condition, called musical hallucinosis.

In a story from August, Host Ira Flatow talks with Dobkin about his decision to publish his account in a medical journal and why the condition is more common than he realized.

Guest: Dr. Bruce Dobkin is a neurologist at UCLA Health.

A Neurologist Investigates His Own Musical Hallucinations

Koalas with the bodies of lions. Elephants the size of your dog. Gigantic, 8-foot-tall sloths. These aren’t creatures found in science fiction: They walked our planet a million years ago, during the Ice Age.

That’s the focus of the third season of the Apple TV series “Prehistoric Planet,” which uses the latest paleontology research and photorealistic CGI to reimagine the lives of ancient creatures. So far, the series has focused on dinosaurs, but now it’s taking that same approach to the huge and strange-looking animals that roamed the tundras and deserts of the Ice Age.

Joining Host Ira Flatow to thaw out the new research featured in the show are two of its scientific consultants, paleontologist Darren Naish and La Brea Tar Pits curator Emily Lindsey.

Guests: Dr. Darren Naish is a paleozoologist and author based in Southampton, U.K.

Dr. Emily Lindsey is a paleoecologist, curator, and excavation site director at the La Brea Tar Pits and Museum in Los Angeles, California.

‘Prehistoric Planet’ Defrosts Strange Animals Of The Ice Age

Since 1955, when Congress passed the Polio Vaccination Assistance Act, the federal government has been in the business of expanding access to vaccines. That is, until this year.

2025 has been filled with almost daily news stories about federal agencies, under the direction of Health Secretary Robert F. Kennedy Jr., casting doubts about vaccine safety, including unsubstantiated claims about links to autism. These agencies have also been taking steps that could roll back access to vaccines, including for hepatitis B and COVID-19.

But we’ve found it very hard to sort out what these talking points and recommendations mean in practice. KFF Health News journalists Jackie Fortiér and Arthur Allen join Host Flora Lichtman to discuss, one year in, what this administration’s stance on vaccines has meant practically—for vaccine access, and vaccine uptake.

Guests: Arthur Allen is senior correspondent at KFF Health News and author of Vaccine: The Controversial Story of Medicine's Greatest Lifesaver.

Jackie Fortiér is a Peggy Girshman fellow covering health policy at KFF Health News.

How Did Vaccine Policies Actually Change In 2025?

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, and the plan is to eventually crash it into the ocean. But wouldn’t it be cooler to send it into deep space instead? A listener pleads his case.

Guests: Dr. Stefanie Milam is an astrochemist at NASA and a project scientist for the James Webb Space Telescope. She studies comets and interstellar objects.

Dr. Hakeem Oluseyi is an astrophysicist and CEO of the Astronomical Society of the Pacific.

Why Astronomers Are Excited About Comet 3I/ATLAS’ Close Approach

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 TOI-561b, a far-off “wet lava ball” which was recently observed by the James Webb Space Telescope. Researchers believe that the planet has the strongest evidence yet of an atmosphere on a rocky planet outside our solar system.

Guests:
Dr. Angela Oliverio is an assistant professor in the department of biology at Syracuse University. 
Dr. Johanna Teske is a staff scientist at Carnegie Science Earth and Planets Laboratory in Washington, D.C.

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

Videos of humanoid robots dancing, doing cartwheels, putting clothes in a washing machine, and serving drinks are all over social media. And tech CEOs are telling us to prepare for the forthcoming humanoid army that’s going to totally change our lives for the better.

But what’s real? Where are we with this technology? Are these humanoids robots ready to take washing the dishes off our plates, or work beside us in warehouses?

Tech journalist James Vincent became an expert on the subject when he toured humanoid robot factories and rubbed shoulders with robots themselves for a feature story he wrote for Harper’s Magazine. He joins Host Flora Lichtman with perspective on the hype.

Guest: James Vincent is a journalist who’s written for The Verge and The Guardian, and author of the book Beyond Measure: The Hidden History of Measurement.

What’s The Reality Behind The Humanoid Robot Hype?

It’s that time of year: the Christmas Bird Count, when birders go out in flocks to record all the birds they see in a single day. The data collected during this annual tradition gets compiled by the National Audubon Society, and helps scientists understand bird population trends across the Americas. 

If you participate in the bird count, chances are you’ll see a lot of the same birds you’d see any other day of the year—think sparrows, blue jays, blackbirds, cardinals. But that doesn’t make them any less special. So this year we’re turning our binoculars on a few (wrongfully) overlooked common birds. 

Producer Kathleen Davis talks with two of our favorite birders, author and illustrator Rosemary Mosco, and conservation scientist Corina Newsome, to share some surprising facts about birds that don’t often make it to the top of pecking order.

Guests:
Rosemary Mosco is an author, illustrator, and speaker whose work connects people with the natural world.
Corina Newsome is a birder and conservation scientist at the National Wildlife Federation, based in Atlanta, Georgia.

Can We Just Throw Our Plastic Garbage Into A Volcano?

The mechanisms behind Alzheimer’s disease have eluded scientists for decades. But a new breakthrough points to lithium as a possible explanation—not only does it occur naturally in the brain, but a deficiency causes dementia in mice. This research is one of thousands of projects that have lost funding due to President Trump’s cuts to the National Institutes of Health (NIH). 

Host Ira Flatow speaks with Alzheimer’s researcher Bruce Yankner about this new finding, and then to epidemiologist Katelyn Jetelina and immunologist Elisabeth Marnik about the country’s “quiet engine of science,” the NIH.

Guests: 
Dr. Bruce Yankner is professor of genetics and neurology at Harvard Medical School in Boston, Massachusetts.
Dr. Katelyn Jetelina, epidemiologist and author of the Your Local Epidemiologist newsletter. She’s based in San Diego.
Dr. Elisabeth Marnik is an immunologist and Director of Science Education & Outreach at the MDI Biological Laboratory in Bar Harbor, Maine.
