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 to the demise of the wrecks themselve...

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 higher risk for conditions like dementia.

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 from the shells of beetles, morph with...

Last spring, a curious listener called with an unusual question about coyote urine. Is it – as advertised by companies who sell it – an effective, all natural pest deterrent? And more importantly: “Who are the coyotes that are providing this urine?”

Since then, producer Taylor Quimby has been trying to find out… and with literal gallons of the stuff available online, he discovered the answers aren’t pretty. 

Today on Outside/In, we p...

It’s a weird time to be an environmental scientist. The proposed cuts to federal science funding in the United States are profound, and if they come to pass, it’s not clear what American science will look like on the other side. But for many researchers, science is much more than a career: it’s a community, lifestyle, and sometimes even a family business. 

Outside/In producer Justine Paradis tagged along with researchers in the fiel...

Helium is full of contradictions. It’s the second most abundant element in the universe, but is relatively rare on Earth. It’s non-reactive, totally inert—yet the most valuable helium isotope is sourced from thermonuclear warheads. 

And even though we treat it as a disposable gas, often for making funny voices and single-use party balloons, our global supply of helium will eventually run out. That’s because, at a rate of about 50 gr...

“In the last days of the fourth world I wished to make a map for those who would climb through the hole in the sky.”

That’s the first line of the poem “A Map to the Next World” by Muscogee writer and former U.S. Poet Laureate Joy Harjo. It’s a piece that’s inspired Aquinnah Wampanoag writer Joseph Lee as he undertakes one of journalism's most nuanced beats: covering hundreds of unique tribal communities. 

Sometimes those stories fit ...

In 1970, marine architect Charlie Canby got an odd assignment: Design a 600-foot ship for an undisclosed purpose and an undisclosed customer. Only after it was built did he finally find out what it was for. 

“I was dumbfounded,” he said. “I drove away in a daze. I could not believe what we were really doing.”

In this episode, reporter Daniel Ackerman tells the unbelievable story of a boat, a government conspiracy, and the birth of a ...

Today on Outside/In, we’re sharing an episode from our friends and partners at Common Land.

Common Land explores the creation stories behind protected land. Each season takes a deep dive into the history, science and politics behind the creation of one particular patch of protected, common land.

Season two of Common Land, produced in partnership with New Hampshire Public Radio, follows documentarian Matthew Podolsky as he attempts to...

When the smash-success Jurassic Park first hit theaters in 1993, it inspired a generation of dinophiliacs and helped to usher in a new “golden age of paleontology.” 

But it also froze the public’s perception of dinosaurs in time, and popularized inaccuracies that people still believe are true today. 

So what happens when the biggest source of information on a scientific field comes from a fictional monster movie? In this episode, thr...

In this episode, we’re taking your questions on the subject of sound. We talk about tinnitus, “the mind’s ear,” and the celebrity voices we have strong feelings about, from Bob Ross to President Obama, Michael Barbaro to Ira Glass.

So strap your earbuds in, we’re going for a ride!

1. What are tintinnabula, and the first wind chimes in the world?
2. What exactly is ASMR, and what makes it feel good?
3. Why does my cat make twitter sounds whe...

Green grass grows everywhere: on baseball fields, in backyards, in front of strip malls. Collectively, we spend billions of dollars every year keeping them fertilized and watered.

But lawns cost more than money in Western states like Utah. Despite a severe drought, residents of Utah’s towns and cities use more water per capita than any other place in the nation, and a majority of that water goes right into lawns. That’s helping fuel...

This summer, more than 100 cruise ships will visit the small city of Portland, Maine, dropping thousands of passengers onto the city’s commercial waterfront for lobster rolls, local souvenirs and a quintessential New England experience. 

But as Portland has rapidly become a landmark destination for cruise lines, a group of activists are calling into question the long held narrative that cruise ships provide a dependable economic boo...

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 his...

One of our listeners is in a pickle. He’s looking to buy an engagement ring but wants to make sure the diamond comes from an ethical and sustainable source. So he sent us an email asking for help. 

This is our latest addition of “This, That, or the Other Thing.” It's a series about the choices we make in our lives to try and build a more sustainable world, whether they have any effect, and what we can do instead if they don't.

Alexis Nikole Nelson, better known to her millions of fans as @blackforager, was raised by a mother who is an avid gardener and a father who loves to cook. Foraging allowed Alexis to fuse her love for wild plants and food from a very young age.

But before Alexis became the @blackforager many know today, there was a period in her life where Alexis lost that love and connection to foraging, and where food became very much the enemy.

Mike Strizki drives the only hydrogen-powered car on the East Coast. That’s because he’s the only person with access to fuel… which he makes, by himself, in his backyard in New Jersey. 

And it’s not just his car. Mike’s house, his lawnmower, even his bicycle are all powered by hydrogen. He’s convinced that this element could be the single most important solution to the climate crisis, if only people and governments would just get on...

Lead is a study in contradictions. It’s dense enough to stop an X-ray, but soft enough to scratch with your fingernail. It’s heavier than steel and iron, but also more flexible. 

And, despite evidence of its toxicity, humans have been using it for all sorts of things for thousands of years. 

In this edition of our series “The Element of Surprise,” we hone in on this notorious heavy metal. What chemical properties make lead so harmful...

In the late 1950s, engineer Herb Ueda Sr. traveled to a remote Arctic military base. His mission? To drill through nearly a mile of ice, and extract the world’s first complete ice core.

To finish the job, he and his team would endure sub-zero weather, toxic chemicals, and life inside a military base… which was slowly being crushed by the glacier from which it was carved. 

In this episode (first released in 2023) Daniel Ackerman takes...
