From the perspective of Western science, plants have long been considered unaware, passive life forms; essentially, rocks that happen to grow.  But there’s something in the air in the world of plant science. New research suggests that plants are aware of the world around them to a far greater extent than previously understood. Plants may be able to sense acoustics, communicate with each other, and...

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 high...

Once again, it’s that wonderful time when scientists everywhere hold their breath as the team opens the Outside/Inbox to answer listener questions about the natural world. Today’s theme is smell: how it works in the nose, the mind, and how much is still unknown about the fifth sense. Question 1: Does it gross you out to know that every time you smell something, a little bit of that thing… is in yo...

Redwood National and State Parks are home to giants: coast redwoods that can grow as tall as a thirty-story building. These ancient California forests support hundreds of different species, and store more carbon than any other forest on the planet. But in the last century, 95% of them were felled by loggers.  Now, scientists have discovered a surprising strategy to foster the next generation of ol...

Will Simone Biles live up to her moniker as greatest gymnast of all time? Will Lebron James and Team USA continue to dominate men's  basketball? And will the Paris 2024 Games be the most sustainable in modern Olympic history? While billions of viewers tune in for the drama of athletes competing on a global stage, climate scientists are tuning in to Paris's climate promises – from the locally sourc...

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...

Introducing the newest series from NHPR’s award-winning Document team: “The Youth Development Center.” New Hampshire has sent its most troubled kids to the same juvenile detention center for more than a century. It's a place that was supposed to nurture them, that instead hurt them – in some of the worst ways imaginable. It's now at the center of one of the biggest youth detention scandals in Amer...

Maybe you’ve looked at the sky on a clear night and spotted the International Space Station, a tiny white dot gliding through the stars. Maybe it felt special, a rare glimpse of a human-made satellite in space.  But what if you were to look up at the sky and see more visible satellites than stars? What if the Big Dipper and Orion were drowned out by  a satellite traffic jam, criss-crossing through...

Consider the potato.  The typical potato is not all that pretty. They can be beige and lumpy, dusty and speckled, and on top of that, they even sprout alien-like tentacles. Further, no one really knows what to make of the potato. Is it a vegetable, or so starchy that we should really consider it a grain?  It’s time for answers. The Outside/In team ventures into the potato patch and presents three...

Ed Yong’s writing about the pandemic in Atlantic Magazine was read by millions of Americans. He won a Pulitzer Prize in 2021 for his coverage.  But behind the scenes, he was struggling with burnout, anxiety and depression.  Host Nate Hegyi sits down with Ed for a conversation about how he decided to step back from pandemic reporting, the benefits (and possible drawbacks) of birdwatching for mental...

What do wolves, waste-water treatment plants, and the Gulf Stream have in common? This episode, that’s what! It’s that wonderful time when we comb through all your wonderful questions and call up some scientists to help us answer them. Some of the more unlikely things that get brought up include dinosaur pee, abandoned shopping carts, and wolves preying on cheese curds.  Here’s what’s on the docke...

Every December, during the Christmas Bird Count, 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 volunte...

The Smithsonian National Zoological Park in Washington, DC is sometimes called “the people’s zoo.” That’s because it’s the only zoo in the country to be created by an act of US Congress, and admission is free. But why did our federal government create a national zoo in the first place? Producer Felix Poon has the scoop – from its surprising origins in the near-extinction of bison, to a look at its...

While digging a well in 1750, a group of workers accidentally discovered an ancient Roman villa containing over a thousand papyrus scrolls. This was a stunning discovery: the only library from antiquity ever found in situ. But the scrolls were blackened and fragile, turned almost to ash by the eruption of Mount Vesuvius. Over the centuries, scholars’ many attempts to unroll the fragile scrolls hav...

The Colorado River – and the people that rely on it – are in a state of crisis. Climate change and overuse are taking a significant toll. Seven states must compromise and reach a solution to prevent the river from collapsing. In late 2023, tensions were running high between the major players in the water world as they convened at the annual Colorado River conference in Las Vegas. LAist Corresponde...

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. Over the past 150 years, that abundance has led production of the silvery metal to skyrocket (pun intended) and created an industry respon...

When officials commissioned a set of updated hazard maps for Juneau, Alaska, they thought the information would help save lives and spur new development. Instead, the new maps drew public outcry from people who woke up to discover their homes were at risk of being wiped out by landslides. What’s followed has been a multiyear project – not to address the challenges posed by climate-fueled landslide...

When it comes to protecting the biodiversity of Planet Earth, there is no greater failure than extinction. Thankfully, only a few dozen species have been officially declared extinct by the US Fish and Wildlife Service in the half-century since the passage of the Endangered Species Act.  But, hold on. Aren’t we in the middle of the sixth mass extinction? Shouldn’t the list of extinct species be… wa...

Shirtless influencers on TikTok and Instagram have acquired millions of followers promoting the carnivore diet. They say studies linking meat consumption and heart disease are flawed — and plant foods are making people sick. "Western medicine is lying to you," says content-creator Dr. Paul Saladino, who co-owns a company selling desiccated cattle organs. The online popularity of the carnivore diet...

Hemp used to be a staple of life in America. King James I demanded that colonists produce it. Hemp rope and fabric were ubiquitous throughout the 18th and 19th centuries. The USDA even produced a WWII newsreel called “Hemp for Victory.” But other materials came to replace hemp – wood pulp for paper, and cotton and synthetics for fabric. Why? For that matter, what is hemp? Is it different from weed...

It’s that special time again! Scientists everywhere hold their breath as the team opens the Outside/Inbox and answers listener questions about the natural world. In this episode, we consider Flaco the Eurasian eagle owl, an impulsive goat purchase, and a big night for salamanders. Plus, we’re graced with Nate’s rendition of a Tom Waits song.  Questions: What would NYC look like in 50 years if huma...

To save for retirement, common knowledge says to “diversify your portfolio.” Give your cash to a company so they can invest it into hundreds of other companies on the stock market. But unless you’ve gone out of your way to change it, your portfolio probably has little to do with your values.  For example, there are climate activists invested in fossil fuel companies. Staunch vegans putting some of...

Editor's Note: This episode first aired in July, 2023 With 'Oppenheimer,' director Christopher Nolan turned the Manhattan Project into an Academy-Award-winning blockbuster. The film is set in Los Alamos, where the first atomic bomb was tested. But few people know the history of Carrizozo, a rural farming area downwind of the test. Radioactive fallout from the bomb settled on everything: the soil,...

If you grew up with family members who pushed (or dragged) you onto the trail, chances are you have strong memories associated with hiking. Epic vistas… swarms of black flies… and your dad’s terrible homemade gorp.  Whether you grow up to see them as personal triumphs or family fiascos, those early adventures can shape your perception of the outdoors for life. Can parents shape kids into hardcore...
