Outside/In

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

Decoding nature's symphony

Outside/In ·

2026/09/30

In 1985, electronic music pioneer Bernie Krause was asked to step in to help save a stranded humpback whale. Krause was known back then for being an evangelist of Moog synthesizers, not a whale whisperer. But from that moment he would go on to become a foundational scientist in the new field of ecoacoustics, or soundscape ecology.In this episode producer Patrick McNameeKing talks to three scientists from the growing field of ecoacoustics. From saving Humphrey the humpback whale, to eavesdropping

A dry river runs through it

Albuquerque and the Rio Grande go hand in hand. The river cuts right through town, which means if you leave your office at closing time, you could have your feet in the water before 6.But, not this past summer. This August, along the river’s middle section, more than a hundred miles ran dry. What scientists have been warning about for decades – the gradual aridification of the desert Southwest – has finally arrived in Albuquerque. So, what was it like for the people who flocked to the river

You might associate it with the foil that wraps leftover pizza and the shiny craft beer cans sold in breweries, but aluminum is literally everywhere. Scoop up a handful of soil or gravel anywhere on Earth and you’ll find atoms of bonded aluminum hidden inside.But even before it was used in everything from airplanes to deodorant, the trade of aluminum minerals helped color the world, finance the Vatican, and led to the mass collection of human urine. In this installment of “The Element of

Noah Wilson-Rich has made it his mission to save the bees — from colony collapse disorder, loss of habitat, and disease. He’s doing this not just as a scientist, but also as an entrepreneur.But is that a good thing? And what happens when you think you know the answer to a solution, only to realize that you got it wrong? “The ‘save the bees’ movement is canceled,” he says. But what should we do in its place?

Cosmic earthquake pizza

When an Outside/In listener asked the team to weigh in on a debate between him and his wife, perhaps we should have hesitated. But it was too good to resist.“We have eighteen-year old twin boys, and sometimes they leave pizza out on the counter. She's convinced it's bad for your health — and I don't think so! Is pizza left overnight on the counter bad for you?” Anthony asked. For some members of the team, the answer was vindicating. For others, it was unmooring. Beyond settling this marital

Scientists spoke up against a de-extinction company....

2026/08/26

When evolutionary biologist Vincent Lynch heard the news that a $10 billion biotech company had brought the once extinct dire wolf back to life, he called foul. He took to the media to argue that these overhyped headlines threatened public trust in science.And that's when things started to get weird. In a story that feels like it came right out of Jurassic Park, we look into the murky world of "dark PR" and discover what happens when the principle of scientific discourse challenges the power of

City Summer, Country Summer

Growing up, Kiese Laymon thought of himself as a city kid. But he spent his childhood with a foot in two worlds: his mom’s house in the capital city of Jackson, Mississippi and his grandma’s house in a rural country town.It wasn’t until Kiese left Mississippi that he came to understand that this question of city versus country actually meant a lot more. It carries a lot of baggage: the tensions between north and south, tectonic historical forces, and the contradictions of life in Mississippi. In

Dean Russell had just wrapped several reporting projects on climate change, mental health, and COVID. “My world was just so serious,” he said. That’s when his boss approached Dean with an idea. What if they made a fiction podcast about climate change?At first Dean wasn’t sold, but a few years later he’s become a full believer, and is the co-creator of WBUR’s The Midnight Rebellion, a choose-your-own-adventure podcast set in a futuristic climate-ravaged Boston.

The sunscreen episode

2026/07/15

As consumers, we’re looking for a lot in our sunscreen. Not only do we want it to protect us from sunburns and skin cancer, we also want it to be invisible, lightweight, waterproof, nontoxic, shelf-stable, and cheap. Can we have it all in one product? Sometimes, the answer might be no. It’s high time for the Outside/In team to take a closer look at this surprisingly high-tech lotion that we apply every day (in theory). We review the definition of SPF, the choice between mineral and chemical

How far would you go for a crow?

2026/07/08

To the American birder, spotting the Tamaulipas Crow is potentially a once-in-a-lifetime event. The crow's range is mostly in Mexico and extends ever so slightly into Texas, specifically in and around a dump called the Brownsville Landfill. Spotting the Tamaulipas — north of the border — means being able to check it off your American Bird Association Checklist. So just how far will die-hard birders go to see this bird? In this episode producer (and first-time birder) Michaela Elias sets out to the

The problem with pickleball

2026/07/01

Pickleball is the fastest growing sport in America. It may also be the most hated. Tennis and basketball players are complaining about losing court space because of an “invasion” of pickleballers. Residents are losing sleep because of the incessant noise. Fights over pickleball have led to a slew of petitions, calls to the police, and even lawsuits. So why do pickleball players love this sport so much? Just how annoying is it to everyone else? And what will it take for everyone to just get

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

In defense of darkness

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
