Outside/In: Where curiosity and the natural world collide. Look around, and you’ll find everything is connected to the natural world. At Outside/In, we explore that idea with boundless curiosity. We report from disaster zones, pickleball courts, and dog sled kennels, and talk about policy, pop culture, science, and everything in between. From the backcountry to your backyard, we tell stories that expand the boundaries of environmental journalism. Outside/In is a production of NHPR. Learn more at outsideinradio.org

In Challenger's wake: The ethics of sending citizens to space 21.01.2026

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 c...

Bill McKibben has changed (but not that much) 14.01.2026

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...

nom nom nom 07.01.2026

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...

Return of the Kiwi Apocalypse: 10 years of Outside/In 31.12.2025

How Broadway’s SFX designers make it rain (and snow) on stage 24.12.2025

Over the past few decades, CGI has allowed directors to put virtually anything they can imagine onto the big screen. But in the world of theater, practical effects still rule supreme.  So how do these special effects wizards make it snow, rain, and gust inside the confines of a theater, where real live audiences are sitting just feet away? And what are the challenges to dumping more than 100 gallo...

The FernGully Effect 17.12.2025

When Avatar came out in 2009, it shattered box-office records.  And even though it was billed as a sci-fi epic featuring blue aliens on a far-away moon, the movie didn’t shy away from a pretty Earth-based message of environmental conservation. So, with a third Avatar hitting theaters this weekend, we were inspired to bust out the popcorn, dim the lights, and play the part of pop culture critics. ...

Time heals all wounds 10.12.2025

Did you know that some species of worms can be cut into multiple pieces and each piece will make a new worm? Some can even make a whole new brain. Wild, right? While not all forms of healing are quite as miraculous as this, the body’s ability to repair itself is pretty darned cool. So today, we’re answering your questions about healing. Like… Why do we pick at scabs? Why do animals lick their woun...

Of Men and Mice 03.12.2025

At any given time, millions of lab mice are being used in research facilities nationwide. And yet nearly all of them can be connected back to a single source: The Jackson Laboratory in Bar Harbor, Maine, where the modern lab mouse was invented. What started as a research project aimed at understanding heredity is now a global business. Research on lab mice has led to more than two dozen Nobel priz...

On the mend: 8 tips on how to repair your clothes 26.11.2025

The garment industry has a giant carbon footprint, labor issues, and a massive waste problem. We have the power to change how and where we shop, but there’s another way to shift our consumption: the practice of repairing our clothes. After all, the most sustainable garment is always the one already hanging in your closet.  But mending is more than a household chore: it can also infuse new joy in o...

Introducing a special three-part series from NHPR’s Document team and Outside/In: Operation Night Cat.  A New Hampshire Fish and Game warden follows a tip to a man’s backyard.

Time flies like an arrow. Fruit flies like a banana. 29.10.2025

According to our unscientific office poll, the annual changing of the clocks has all the popularity of a root canal. With few exceptions, people described the shift to and from Daylight Saving Time as disorienting, arbitrary, and unwelcome. On a more existential level, winding the clocks back and forth reminds us that no matter how concrete minutes and hours may feel, the way we perceive time is f...

Critical Mast 22.10.2025

Every so often, oak trees go into overdrive. During these so-called mast years, the gentle patter of falling acorns grows into a mighty downpour and ripples across and over ecosystems like a flood.  What happens when a small thing goes from scarce to plentiful? When a player usually hidden behind the scenes vaults onto the main stage?   From swimming squirrels and bug-infested weddings, to an expl...

On the edge of the ice 15.10.2025

Thwaites Glacier in Antarctica is massive, bigger than the state of Florida. If it collapses, it could reshape every coast on this planet during this century. That’s why it’s sometimes known as “the Doomsday Glacier.” And yet, until recently, we knew very little about it. Because Thwaites is extremely remote, reachable only by crossing the wildest ocean on the planet, scientists had never observed...

The Brick Lady of St. Louis 08.10.2025

Ever since a tornado tore through one of St. Louis, Missouri’s poorest neighborhoods, there are piles of bricks all over the place.  It’s not just a debris problem. Bricks in St. Louis have a long and complicated history here – the darling of many historic preservationists and a good source of profit to just as many demolition crews.  Producer Marina Henke spent a week in North City, tagging along...

O/I Trivia: Natural Selection 01.10.2025

What do pastries have to do with environmental justice? Cat butts with the climate crisis? And what US president ate a half-chewed piece of salmon leftover from a bear on reality TV? Grab a pencil (and maybe a pint?) and get ready for the inaugural Outside/In trivia episode we’re calling “Natural Selection.” We’ve got a game called “Guess That Animal!” We’re testing our panel’s knowledge on the en...

How to solve the climate crisis in 60-90 minutes 24.09.2025

When designer Matt Leacock decided to make a board game about climate action, he knew he wanted to make it – first and foremost – fun to play. “If we sold anything as an educational game… people would run screaming and running for the hills,” he told us.  But can simulating the climate crisis really make for a good Friday night with your friends? What are the limits to gamifying social issues as c...

Why is there so much roadkill? 17.09.2025

For humans, roads epitomize freedom. For wildlife, it’s a different story: a million animals are killed by cars every day in the US alone. How did our infrastructure turn so deadly? And what are people trying to do about it? In this episode, we look at how two very different species are impacted by roads. Along the way, we visit a turtle rescue clinic, and hear about a celebrity cougar that was tr...

The cold truth about refrigeration 10.09.2025

In the early 1900s, people didn’t trust refrigerated food. Fruits and vegetables, cuts of meat… these things are supposed to decay, right? As Nicola Twilley writes, “What kind of unnatural technology could deliver a two-year old chicken carcass that still looked as though it was slaughtered yesterday?” But just a few decades later, Americans have done a full one-eighty. Livestock can be slaughtere...

All Wings Considered 03.09.2025

We’re catching some air this week, and talking things with wings!   Quandaries range from the practical (how do different animal and insect wings differ?) to the ethereal (this includes dragons). Here’s the questions we’ll be answering… What makes wings different? How have wings in nature inspired human flight?  Did we ever solve the colony collapse problem with bees? Why do so many cultures have...

Saving the shipwrecks of Stellwagen Bank 27.08.2025

Shipwrecks captivate our imagination, and are the subject of many books, academic papers, and movies—from the world-famous Titanic, to sunken World War II warships, to ancient fishing canoes. Some describe them as time capsules of our maritime history, waiting to be discovered and opened. But there’s a group of people who are drawn to shipwrecks for very different reasons, and it sometimes leads t...

Your brain on GPS 20.08.2025

GPS is essential these days. We use it for everything, from a hunter figuring out where the heck they are in the backcountry, to a delivery truck finding a grocery store, to keeping clocks in sync. But our reliance on GPS may also be changing our brains. Old school navigation strengthens the hippocampus, and multiple studies suggest that our new reliance on satellite navigation may put us at highe...

Taxonomy's 200-Year Mistake 13.08.2025

Fungi used to be considered plants. Bad plants. Carl Linnaeus even referred to them as “the poorest peasants” of the vegetable class. This reputation stuck, and fungi were considered a nuisance in the Western world well into the 20th century. Patricia Ononiwu Kaishian is trying to rewrite that narrative. Her new book, Forest Euphoria: The Abounding Queerness of Nature catalogs fungi that sprout fr...
