What A Snow Drought In The West Means For The Rest Of 2026

While parts of the eastern and southern US have had unusually high snowfall this year, the West is in a snow drought. The abysmal winter sports season is just the tip of the melting iceberg: Snowpack is key to providing water throughout the year for the drought-stricken region. Joining Host Flora Lichtman to talk about this unusual winter are reporter David Condos and climate scientist Brad Udall. Guests: David Condos is the Southern Utah Reporter at KUER based in St. George. Brad Udall is a senior water and climate research scientist at Colorado State University’s Colorado Water Center.

Jump, Spin, Glide: The Science Of Figure Skating

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 speeding skater. Guest: Dr. Deborah King is a professor of exercise science and athletic training at Ithaca College in Ithaca, New York.

How Are State-Run Psilocybin Therapy Programs Going?

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, including drug-resistant depression and PTSD. With a lot more people taking the drug under state supervision, what are we learning about its safety and efficacy? Who is taking it, and can clinics make money? Host Flora Lichtman checks in on the state of these programs with Colorado Public Radio journalist Alejandro Galva. Then, she sits down with geriatric and palliative care specialist Stacy Fischer for a research update on the therapeutic use of the drug, and the nation’s largest clinical trial for psilocybin use for advanced cancer patients facing mental health challenges. Guests: Alejandro Galva is the afternoon editor at Colorado Public Radio. He’s also the editor of their series “The Trip,” which covers the psychedelic therapy landscape in the state. Dr. Stacy Fischer is a geriatric and palliative care specialist at UCHealth University of Colorado Hospital. Transcripts for each episode are available within 1-3 days at sciencefriday.com.

A Little Grime Can Boost Kids’ Health. But What Kind?

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 microbiologist and professor at the Scripps Institution of Oceanography and in the department of pediatrics in UC San Diego School of Medicine. Dr. Amber Fyfe-Johnson is an associate professor and pediatric epidemiologist at Institute for Research and Education to Advance Community Health at Washington State University.

Mating, Marriage, And Monogamy In The Age Of Apps

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 new book, The Intimate Animal: The Science of Sex, Fidelity, and Why We Live and Die for Love. Guest: Dr. Justin Garcia is an evolutionary biologist and executive director of the Kinsey Institute. He is the author of The Intimate Animal.

What A Tea Party With A Bonobo Taught Us About Imagination

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 Amalia Bastos about Kanzi, what it means to imagine, and how our definition of “humanness” keeps changing. Guest: Dr. Amalia Bastos is a cognitive scientist at the University of St. Andrews in Scotland. Transcripts for each episode are available within 1-3 days at sciencefriday.com.

How Is Screen Time Affecting My Kid?

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 developmental pediatrician Jenny Radesky. Guests: Dr. John Foxe is Director of The Del Monte Institute for Neuroscience at the University of Rochester in New York. Dr. Jenny Radesky is a developmental behavioral pediatrician at the University of Michigan in Ann Arbor. She’s also co-Medical Director of the American Academy of Pediatrics Center of Excellence on Social Media and Youth Mental Health.

Who Wants To Smell An Ancient Embalmed Mummy?

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 perfumer Carole Calvez about how they scientifically recreated the scent of ancient Egyptian mummies and brought that smell to museums on special cards. Guests: Dr. Barbara Huber is an archeo-chemist at the University of Tübingen in Germany. Carole Calvez is a perfumer and olfactory designer and a cofounder of Iris & Morphée in Paris, France.
