| 6/17/26 | ![]() Big porpoise energy | Whales have Free Willy. Dolphins have Flipper. But what about the humble porpoise? The porpoise doesn’t star in any Hollywood blockbusters. These shy, elusive “deer of the sea” are often overshadowed by their more charismatic cousins – but don’t let their social anxiety fool you. In fact, porpoises are speed-fiends with an insane metabolism and an outrageous sex drive. Host Nate Hegyi and producer Marina Henke explore the Olympic sprinters of the sea and wonder if the fate of the endangered vaquita might hinge on being oh-so-very-cute. Featuring Michelle Dutro, Barb Lake and Ruxandra Guidi. Produced by Nate Hegyi. For full credits and transcript, visit outsideinradio.org.

| 2/11/26 | ![]() That's so raven | Ravens get a bad rap in western culture. They’re an ominous symbol of death, considered “unclean” by the bible, and star in Edgar Allen Poe’s haunting gothic poem, “The Raven.” A group of ravens is called an “unkindness.” What a burn. But host Nate Hegyi is on a mission to show that we should give the raven a bit more credit. It’s one of the most intelligent creatures on earth — an animal that can use tools like a chimpanzee, speak like a parrot, do tricks like a dog, and investigate murders like Sherlock Holmes. So today on the show, another edition of our ongoing series, Holy Scat: raven edition. Featuring Sophie Nilles and Will Geiger. Produced by Nate Hegyi.

LINKS Dr. Kaeli Swift is one of the foremost corvid researchers on the planet, and she’s done a deep dive into corvid funerals. Here’s the study that shows ravens parallel great apes in terms of intelligence.

| 2/4/26 | ![]() The Emerald Forest | After the Irish fought for and won their independence from the British in 1921, they had a problem. Centuries of exploitation had left the island one of the least forested nations in Europe, with less than 2% tree cover. So, they started planting a non-native American tree: fast-growing Sitka spruce capable of rebuilding their timber resources in record time. And it worked. Today, about 17% of the island is forested. But in the rural areas where iconic rolling hills have been replaced by rows and rows of conifers, farmers are not happy. Outside/In host Nate Hegyi takes us to County Leitrim, an area of Ireland hit hard by the Troubles and the Great Famine, to meet the townspeople who are fighting what they say is a new wave of colonialism: Sitka spruce plantations. Featuring Justin Warnock, Brian Smyth, Donal Magner, Liam Byrne and Jodie Asselin. This episode originally aired in March 2025. Produced by Nate Hegyi.

Sitka spruce plantations are controversial in other parts of Ireland as well, including Cork. There are also efforts to rewild parts of Ireland with entirely native trees and to protect and restore carbon-sequestering bogs. It can be really tough to figure out exactly what was growing in Ireland thousands of years ago – but these scientists used ancient pollen counts to figure it out. Researchers at University College Dublin produced a detailed socio-economic impact report on Sitka spruce plantations and County Leitrim in 2019. Learn more about your ad choices.

| 1/29/26 | ![]() Safe to Drink, Episode 1: You don’t know about this? | A New Hampshire town finds out its water has been contaminated by a chemical. The most basic question — whether the water is safe to drink — doesn’t have a clear answer. Nobody seems to know much about this so-called forever chemical, which is weird… because all of this has all happened before. From the Document team at New Hampshire Public Radio, Safe to Drink is a four-part series about a water contamination story that keeps repeating in town after town — and about the people who fought for answers through a maze of chemistry, regulations, and illnesses. You can binge the whole series now: subscribe to Safe to Drink on Apple Podcasts, or check out their page on NHPR’s website. Reported by Mara Hoplamazian.

| 1/28/26 | ![]() Remembering Christa | Last week, we talked about the ethics and regulations around sending private citizens to space, but one thing we didn’t linger on much was the lasting impact of Christa McAuliffe; the teacher slated to become the first private citizen to space before she was killed in the Challenger disaster. So today, we’ve got a series of stories and interviews that are all part of NHPR’s series “Remembering Christa: 40 Years After the Challenger.” We’ll hear from a local journalist that covered her story, the students she mentored, and the community charged with remembering her legacy.

| 1/21/26 | ![]() In Challenger's wake: The ethics of sending citizens to space | In 1985, high school teacher Christa McAuliffe was selected to become the first private citizen to travel to space. After the Challenger explosion that killed her and 6 other astronauts, NASA scrapped its Teacher in Space Project; it was still too risky to send private citizens to space. 40 years later, things are looking very different. Today, celebrities and billionaires are buying trips on commercial rockets. Private companies are designing new, private space stations. How is safety being regulated for these private space companies? And what happens if – or when – something goes wrong?

| 1/14/26 | ![]() Bill McKibben has changed (but not that much) | One of the very first books for the general public about climate change was written and published by Bill McKibben in 1989. In The End of Nature, Bill wrote that continuing to burn fossil fuels would “lead us, if not straight to hell, then straight to a place with a similar temperature.” Bill was right. The planet is hotter. Climate disasters are everywhere. You’d think he’d be more upset now than ever. But in his latest book, Here Comes the Sun, Bill sounds optimistic. In it he writes “For the first time, I can see a path forward. A path lit by the sun.” Host Nate Hegyi talks to journalist and activist Bill McKibben, about how he’s changed, how he’s stayed the same, and what his story tells us about the state of the climate crisis.

| 1/7/26 | ![]() nom nom nom | You might not think much about the sticky bottle of vanilla sitting in the back of your pantry. But that flavor – one of the most common in the world – has a fascinating history, involving a fickle orchid and a 12-year-old enslaved boy who made the discovery of a lifetime. That’s the sort of tale that attracts poet Aimee Nezhukumatathil. From peacock feathers to the sounds of garden insects, her work is known for magnifying the wonders of the natural world. Her latest book of essays, “Bite by Bite: Nourishments and Jamborees,” explores the unexpected connections between food, memory, and community. So take a seat and pour yourself an aperitif, as Aimee Nezhukumatathil shares a few of these miniature morsels with Outside/In host Nate Hegyi: a three-course meal of grape jelly, sweet nostalgia, and just a hint of vanilla bean.
