    In defense of darkness
    2026/05/20
    Megan Eaves-Egenes grew up under the very starry skies of rural New Mexico. During those years, she developed a deep appreciation for astronomy. The fascination is, of course, not hers alone. But, a starry sky requires one pretty important ingredient: darkness. One study recently reported that since 2011, the night sky has gotten brighter at about 10% per year. All that light pollution has brought dire consequences to life on planet earth. Crickets can’t tell whether it’s day or night, bird migrations have gone haywire, and our own natural alarm clocks are constantly confused. In a world where switching on a lamp during evening hours is, as Megan writes, “almost as basic as breathing” is there hope for our night skies? Or have we illuminated our way to a point of no return? Featuring Megan Eaves-Egenes. SUPPORT To share your questions and feedback with Outside/In, call the show’s hotline and leave us a voicemail.

  • Life and death and psilocybin

    Life and death and psilocybin
    2026/05/13
    President Trump recently signed an executive order to make certain psychedelic drugs more available to treat mental health conditions like depression and PTSD. Robert F. Kennedy Jr. and Joe Rogan were in the oval office, and President Trump even joked during the signing ceremony, “can I have some, please?” Maybe this executive order wasn’t on your 2026 political bingo card… but interest in these substances for mental health isn’t new. In this episode, we’re revisiting the story of Kathy Kral. In the midst of her battle with cancer, Kathy found herself facing a diagnosis of major depression. So, she signed up for a clinical study to see if psilocybin – the psychedelic compound found in “magic mushrooms” – could help her confront her fears about cancer and death, as well as her deepest inner demons. This episode was first published in 2023. Featuring Kathleen Kral, Manish Agrawal, and Norma Stevens. Produced by Felix Poon. For full credits and transcript, visit ⁠outsideinradio.org⁠.

  • Silicon Planet

    Silicon Planet
    2026/05/06
    Like a typecast actor who can’t escape the blockbuster franchise they’re known for, the element of silicon is inescapably associated with Silicon Valley. But that association undersells just how important, how foundational silicon is for human civilization. It’s another edition of “The Element of Surprise,” our occasional series about the hidden stories behind the periodic table’s most unassuming atoms, isotopes, and molecules. And this time, it’s all about silicon. From humankind’s early tools, to the quartz crystal hidden in your digital watch, we’ll cover how this underrated element has a lot more to offer than one California valley might suggest. Featuring Vince Beiser, Megan Brewster, and Rachel Maines. Produced by Taylor Quimby. For full credits and transcript, visit outsideinradio.org.

  • A Dry Hot American Summer

    A Dry Hot American Summer
    2026/04/29
    In the spring of 1936, the producer of King Kong hauled a film crew to the desert of Arizona to shoot a sweeping romantic epic. But the heat was so punishing that it melted film stock, caused the lead actress to pass out, and killed the production’s mascot – a baby camel. It was the beginning of a heat wave that parked itself over America for months, quickly becoming one of the deadliest natural disasters in our country’s history. It blew up sidewalks, cooked onions in the ground, claimed at least 12,000 lives, and turned the United States into a literal frying pan. Host Nate Hegyi talks with Geoff Williams, author of the forthcoming book The Summer of Death, about a ‘heat horror show’ that transformed American life 90 years ago, and what lessons it gives us on how to survive a hotter world today.

  • Like a Dirty Rotten Whale

    Like a Dirty Rotten Whale
    2026/04/22
    We’re cleaning out the proverbial fridge, but instead of old food, it’s fantastic and forgotten questions from the Outside/Inbox. Conversation topics include Taylor’s humiliatingly old headlamp, the olfactory experience of a dead whale and, of course, the answers to the following queries… Why do dogs like to roll in dead stuff? Do humans have a mating season? Why do so many deer collisions happen in November? When did headlamps start to have red light? I live next to a highway. What can I do about the noise pollution? In the final Lord of the Rings movie, there’s a crust that forms on top of the lava that the ring is thrown onto. Is that legit? Featuring Christopher Schell, Eric Nystrom, and Erica Walker. Thanks to our listeners who called in: Dusty, Kyle, Claire, Amanda, Gretchen, Zach, and Sabrina. We’re looking for new submissions to the Outside/Inbox!

  • The Dead Bird Rabbit Hole

    The Dead Bird Rabbit Hole
    2026/04/15
    Every December, tens of thousands of volunteers look to the skies for an international census of wild birds. But during migration season, a much smaller squad of New York City volunteers take on a more sobering experience: counting dead birds that have collided with glass buildings and fallen back to Earth. In this episode, we find out what kind of people volunteer for this grisly job, visit the New York City rehab center that takes in injured pigeons, and find out how to stop glass from killing an estimated one billion birds nationwide every year. This episode was first produced and published in the spring of 2024. Featuring Melissa Breyer, Linda LaBella, Gitanjali Bhattacharjee, Katherine Chen, and Tristan Higginbotham.

  • The Microplastics Cleanse

    The Microplastics Cleanse
    2026/04/08
    With the ubiquity of plastic products, it’s maybe no surprise that a growing body of research shows tiny pieces of plastic are getting inside of us. But what is all this plastic doing to our bodies? And once it’s there… is there any way to get it out? Producer Haleema Shah looks at what the research says (and doesn’t say) about plastic and health, and explores a new trend in wellness: the microplastics cleanse. Featuring Charmaine Dahlenburg, Marcus Garcia, Yael Cohen, and Sarah Morath. Produced by Haleema Shah. For full credits and transcript, visit outsideinradio.org. Learn more about your ad choices.

So what brought this improbable duo together? The answer is under your feet.
