We've figured out how to harness renewable energy from many natural systems, like solar, wind, and geothermal power. But what about the ocean’s waves? It might seem like converting wave power into electricity on a large scale would’ve been figured out by now, but the tech is actually just getting its sea legs. Why has it been so hard to develop? And just how promising is it?Host Flora Lichtman talks with Oregon Public Broadcasting reporter Jes Burns, who reported on Oregon’s massive wave energy test site; and then she checks in with Deborah Greaves, an offshore renewable energy researcher, for a look at what’s happening in the rest of the world.Guests: Jes Burns is a science and environment reporter and host of "All Science. No Fiction." at Oregon Public Broadcasting.Dr. Deborah Greaves is a professor of ocean engineering at the University of Plymouth in England.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

For Halloween, we bring you an ode to three quintessentially creepy creatures: bats, arachnids, and snakes. First, bat researcher Elena Tena joins Host Flora Lichtman to describe tracking the greater noctule bat in flight and learning that it can feed on migratory birds. Then, arachnologist Paula Cushing describes the camel spider, which is neither a camel nor a spider. And herpetologist Sara Ruane highlights one of her favorite snakes, the tiger keelback, which is both venomous and poisonous. Plus, what makes a lake spooky? A pond possessed? Flora talks with Geo Rutherford, creator of the Spooky Lake Month series on TikTok and Instagram, to learn about some of the spookiest, most mysterious lakes on the planet. Guests:Dr. Elena Tena is the national coordinator for the Spanish Bat Atlas project.Dr. Paula Cushing is senior curator of invertebrate zoology at the Denver Museum of Nature and Science in Denver, Colorado. Dr. Sara Ruane is curator of herpetology at the Field Museum in Chicago, Illinois.

There’s an established playbook for getting one’s affairs in order before death—create a will, name legal guardians, and so on. But there’s also a newer consideration: what will happen to our digital presences, like social media accounts, files, photos, videos, and more. So how do we manage them, and make sure we’re not turned into AI chatbots without permission? (It does happen.) Information scientist Jed Brubaker studies digital afterlives, and joins Host Flora Lichtman to discuss how we can manage our digital legacies. Guest: Jed Brubaker is an information scientist and head of the Digital Legacy Clinic at the University of Colorado, Boulder.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

At first blush, the plots of many horror movies don’t seem particularly appealing. Take “The Shining”: A murderous psychopath tries to kill his family in a haunted, secluded hotel. But horror movies have had devoted fans for as long as they’ve been around, and lately, scary movies and television shows like “Sinners” or “The Walking Dead” have made a big splash. Why? What draws us to horror? And why are some people more thrill-seeking or morbidly curious than others? Host Flora Lichtman talks with two psychologists on opposite poles of horror fandom to flesh out some of the answers: horrorphile and behavioral scientist Coltan Scriver, and psychology professor Ken Carter, who’s horrified by horror. Guests: Dr. Ken Carter is a psychology professor at Emory University and the author of Buzz!: Inside the Minds of Thrill-Seekers, Daredevils, and Adrenaline Junkies. Dr. Coltan Scrivner is a behavioral scientist at Arizona State University and the author of Morbidly Curious: A Scientist Explains Why We Can’t Look Away.

For decades, peanut allergies were on the rise in the US. But a study released on October 20 found that peanut allergies in babies and young children are now decreasing. This drop correlates with a change in guidance from the National Institute of Allergy and Infectious Diseases. In 2017, the agency started recommending exposing children to peanuts “early and often.” Since that recommendation, the prevalence of peanut allergies has dropped significantly.Sharon Chinthrajah, a physician specializing in allergies and immunology, churns through the findings with Host Flora Lichtman. Guest: Dr. Sharon Chinthrajah is a physician specializing in allergy and immunology at the Sean N. Parker Center at Stanford University.Transcripts for each episode are available within 1-3 days at sciencefriday.com. Subscribe to this podcast.
