In the new movie “Whalefall,” a scuba diver (Austin Abrams) gets accidentally swallowed by a sperm whale. What follows is a tense battle against time and the whale’s digestive system, to escape before his air supply runs out.  But could a whale actually swallow a human? And how might this play out in real life? Joining Flora to weigh in are sperm whale biologist Shane Gero, and “Whalefall” director Brian Duffield.  Wondering how you’d fare inside a sperm whale’s stomach? Read more here. Guests: Brian Duffield is the director of “Whalefall.” He is based in Los Angeles, California. Dr. Shane Gero is a whale biologist and biology lead for Project CETI based in Ottawa, Ontario.  Transcripts for each episode are available within 1-3 days at sciencefriday.com.  Subscribe to this podcast.

With the midterms approaching, politicians are out in full force to convince voters to elect them. And that means that we’re hearing a lot of “politician speak.” You know it when you hear it: those folksy turns of phrase, the vague promises.  But what do linguists have to say about this vocal register? How has politician speak changed over time? Does the way someone pronounces their As signal something about their values? Sociolinguist Valerie Fridland joins Flora to decode politician speak. Guest: Dr. Valerie Fridland is a professor of linguistics at University of Nevada, Reno. Transcripts for each episode are available within 1-3 days at sciencefriday.com. Subscribe to this podcast.

An unwelcome visitor is arriving on beaches from West Africa to the Caribbean, and Brazil to Florida. It’s brown, it’s stinky, and it’s more abundant than ever: sargassum. This free-floating seaweed has become a major problem for coastal ecosystems, communities, tourism, and infrastructure.  So what is fueling the sargassum superbloom? And is there anything to do about it? Flora chats with satellite oceanographer Brian Barnes about sargassum biology, why the blooms are so hard to deal with, and what we could do about it. Guest: Dr. Brian Barnes is an oceanographer and associate professor at the University of South Florida.  Transcripts for each episode are available within 1-3 days at sciencefriday.com.

In the past few years, the idea of attachment styles has taken off, both online and in therapy offices. It’s gone from a niche psychological concept to a shorthand to describe how we show up in relationships. Here’s a crash course: Anxious attachment is when you seek constant reassurance. Avoidant attachment is when you flee when someone tries to get close. Fearful-avoidant, also called disorganized, is some combination of the two. And secure attachment is a more regulated approach to relationship stress.  But where does your attachment style come from? Do you have more than one? Can it change? And are the ideas we hear from influencers at odds with how psychologists understand attachment theory? Flora talks with neuroscientist Amir Levine, who has written two books about attachment styles, “Attached” and “Secure.”  Want to learn more about your attachment styles? Take this survey.  Transcripts for each episode are available within 1-3 days at sciencefriday.com. Subscribe to this podcast.

A new mRNA flu vaccine made by Moderna was approved by the FDA in August, and is currently available for people aged 50 and over. The promise of an mRNA vaccine for flu is that it can be spun up more quickly than a traditional vaccine, meaning it could better match the flu strain that’s circulating.   Is that what happened this year? How are the side effects? And how has dysfunction at the health agencies impacted rollout? Flora discusses these questions and more with vaccine researcher Anna Durbin. Guest: Dr. Anna Durbin is a vaccine researcher, professor of international health, and director of the Center for Immunization Research at the Johns Hopkins Bloomberg School of Public Health.

A Kelvin wave has reached California and is creeping up the West Coast, raising both sea levels and concerns from government officials. This kind of massive internal wave begins in the western Pacific Ocean and then travels eastward to the Americas along the equator, and then up and down the coastline. While it might raise sea levels up to 12 inches, it stays below the surface instead of crashing on the shore. Host Flora Lichtman speaks to oceanographer Andrew Leising to get the lowdown on what exactly a Kelvin wave is, and how wary West Coasters should be. Guest: Dr. Andrew Leising is a research oceanographer at NOAA Southwest Fisheries Science Center in San Diego, California.

On Science Friday, we love to talk about ideas, especially ideas that have the power to shape the future. But there are plenty of groundbreaking ideas that almost don’t make it out of the lab or the art studio: ideas that are birthed but then fall into a deep slumber until, years later, they’re reawakened. Why this happens is the subject of the new book, “Sleeping Beauties: Why Good Ideas Go Dormant and How They Wake Up,” by David Bryne, artist, musician, and lead singer for Talking Heads. He joins Flora to explain.  Watch the interview on YouTube. Read an excerpt from “Sleeping Beauties.” Guest: David Byrne is an artist, musician, and the lead singer for Talking Heads.

John Wilson’s new documentary, “The History of Concrete,” has a subject matter that to most people may seem gray, drab, and boring. The film is anything but. Alongside facts about concrete’s reliance on dwindling sand reserves and New York City’s crumbling infrastructure, there are unexpected tangents. Following the idiosyncratic format of Wilson’s hit HBO show “How To,” he tells the stories of a struggling musician, a man who preserves tattoos, and a group of runners looping the same block for two months. Ira talks with documentarian John Wilson about the documentary and their shared appreciation of concrete. Guest: John Wilson is an NYC-based documentarian best known for his HBO series “How To with John Wilson.”  Transcripts for each episode are available within 1-3 days at sciencefriday.com.

Big news for tiny cats: an itty-bitty three-pound spotted cat from Bolivia—called the tilcayo—is the first new wild cat species described in more than a hundred years.  Tilcayo pics have been all over the news and social media, but there’s much more to tilcayo’s tale, including the surprising story behind its discovery.  Flora chats with Paola Nogales-Ascarrunz, the biologist who worked for nearly 10 years to describe this flashy feline. They also discuss how Paola met the tilcayo, why it was so hard to classify, and what the reaction has been in Bolivia. Guest: Paola Nogales-Ascarrunz is a National Geographic Explorer and biologist leading the Bolivian Felid Research and Conservation Program. She’s based in Bolivia.  Transcripts for each episode are available within 1-3 days at sciencefriday.com.  Subscribe to this podcast.

In 2024, scientists using instruments on board the Lunar Reconnaissance Orbiter spacecraft spotted a new large impact crater on the surface of the moon. Tyler Powell joins host Flora Lichtman to describe what they found, and what scientists are learning about the lunar surface from studying it.  After, Sofia Sheikh describes different approaches to hunting for intelligent alien life through ‘technosignatures’. These are technological traces that could only be produced by intelligent life, like radio transmissions, industrial pollution, or city lights at night. Researchers from the SETI Institute have proposed sifting through lunar dust to look for tiny traces of a long-gone super advanced galactic civilization. Guests: Dr Tyler Powell is a planetary scientist at the Johns Hopkins Applied Physics Laboratory.  Dr. Sofia Sheikh is a Technosignature Research Scientist at the SETI Institute.
