Figure skating is a fan favorite at the Winter Olympics—for every event, the stands are packed to watch competitors glide, jump, and spin. But what does it take to pull off these seemingly effortless moves? Figure skating researcher Deborah King joins Host Ira Flatow to unfold the science of the sport, from the impressive jumps of US skater Ilia Malinin, to the g-forces endured by the ankles of a...

In Oregon and Colorado, you can book an appointment for psilocybin therapy, where a licensed therapist takes you on a guided trip using the drug that makes “magic” mushrooms hallucinogenic.Under federal law, psilocybin is illegal. But within the past few years, both states greenlit the drug for supervised medical use, and New Mexico may soon follow. It’s being used to treat certain conditions,...

You may have heard that a little dirt is good for kids. It helps them build up their immune systems, and sets them on a path to future health. But what kind of filth does the trick? Producer Kathleen Davis digs into the latest science on the benefits of exposing kids to the outdoors with microbiologist Jack Gilbert and pediatric epidemiologist Amber Fyfe-Johnson.Guests:Dr. Jack Gilbert is a...

With so many dating apps—and so many people using them—why are a record number of American adults single? Is marriage as important as it was a generation or two ago? Evolutionary biologist and sex researcher Justin Garcia joins Host Flora Lichtman to talk about dating and mating, and what evolutionary biology can tell us about our need to form a “pair bond” … or not.Read an excerpt from Justin’s...

Our ability to imagine is part of what makes us who we are—not just as individuals, but also as humans. It turns out, though, that we may not be the only species capable of playing pretend. In a string of experiments, scientists sat down, set the table, and hosted pretend tea parties with a bonobo named Kanzi to see if he’d play along—and he did.Producer Kathleen Davis chats with study author...

Screens are ubiquitous in today’s world, and concerns about how they affect kids are mounting. Last month, Australia banned social media use for kids under 16, with some European countries poised to follow. But what’s the science on how neverending YouTube videos or TikToks affect kids’ brains and bodies? Joining Host Flora Lichtman to discuss are neuroscientist John Foxe and behavioral...

Wandering through a museum, you can get a glimpse of what life in ancient societies looked like. But what did it smell like? And is it even possible to get a whiff of, say, a freshly embalmed mummy, or a 5,000-year-old Saudi Arabian incense burner? That’s exactly what some chemists and olfactory designers are trying to do.Producer Kathleen Davis talks with archeo-chemist Barbara Huber and...

Cyanobacteria may be the ultimate lesson in resilience. These 3.5 billion-year-old organisms have lived through hell-on-earth conditions, and found creative ways to persevere. While the state of the world feels out of control, Host Flora Lichtman talks to molecular microbiologist Devaki Bhaya about the planet’s ultimate survivalists.Guest: Dr. Devaki Bhaya is a molecular microbiologist at...

The Relativistic Heavy Ion Collider (RHIC), the largest particle collider in the United States, collided its last particles in early February. RHIC is a massive accelerator ring and set of instruments based at New York’s Brookhaven National Laboratory, and was designed to accelerate gold ions to near-light speed before collision. It was the second most powerful accelerator on the planet, second...

This year’s Winter Olympics feature a new event called “skimo,” or ski mountaineering. The racing event involves periods of skiing uphill using “skins” for traction, sprinting uphill on foot, and a downhill ski slalom to the finish. Mountaineering historian Peter Hansen joins Host Flora Lichtman for an introduction to skimo, and the scientific connections of early modern mountaineers. Then,...
