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.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

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. Transcripts for each episode are available within 1-3 days at sciencefriday.com.  Subscribe to this podcast.

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.Transcripts for each episode are available within 1-3 days at sciencefriday.com.  Subscribe to this podcast.

It’s winter, and the SciFri team is already dreaming of warmer weather. How about a mind vacation to one of the hottest places on earth, an erupting volcano? Tamsin Mather has trekked to volcanoes in Chile, Guatemala, Italy, and beyond to learn their secrets. She joins Host Flora Lichtman to field your burning volcano questions, like what’s the deal with glass shards that look like hairballs? Guest: Dr. Tamsin Mather is a professor of Earth sciences at the University of Oxford in the UK.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

The sound of a choir performing in a cathedral is iconic for a reason. It’s this beautiful human experience: being side-by-side with other people, feeling the sound vibrate through you, reverberating around the space.But how long has that been a part of our culture? And what role did sound play in the lives of people who lived during the Ice Age or the Stone Age? That’s the focus of a growing field of archaeology called archaeoacoustics, where researchers use the scientific tools of today to investigate the role of sound and music in the past.To learn more, Host Flora Lichtman is joined by Margarita Díaz-Andreu, principal investigator of the Art Soundscapes project, and Rupert Till, head of the department of humanities at the University of Huddersfield in the UK.Guests: Dr. Margarita Díaz-Andreu is an ICREA professor at the University of Barcelona in Spain and principal investigator of the Art Soundscapes project. Dr. Rupert Till is a professor of music and head of the department humanities at the University of Huddersfield in the UK.Transcripts for each episode are available within 1-3 days at sciencefriday.com.
