O/I Trivia: Natural Selection
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 i
How to solve the climate crisis in 60-90 minutes
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
Why is there so much roadkill?
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
The cold truth about refrigeration
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 car
All Wings Considered
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… • Wha
Saving the shipwrecks of Stellwagen Bank
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 marit
Your brain on GPS
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 changi
Taxonomy's 200-Year Mistake
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 centur
People are buying coyote urine. Where does it come from?
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 thi
Field reports from the cutting edge of science
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 man
The Element of Surprise: The $1,000 Balloon
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
A Map to the Next World
“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’
The Trojan Seahorse
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
A 2,200 Mile Podcast
Today on Outside/In, we’re sharing an episode from our friends and partners at Common Land. (https://commonland.wildlensinc.org/season-two) Common Land (https://commonland.wildlensinc.org/season-two) explores the creation stories behind pro
What Jurassic Park got wrong (and right) about dinosaurs
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 popular
Phallic windchimes and ASMR: the magic of sound
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
Lawn and Order
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.
Cruise-o-nomics
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
Where the Wild Things Grow
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 Ki
A Righteous Gemstone
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,
Foraging made her famous
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
The future was hydrogen
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,
Black Sheep Metal
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
The Cold War Ice Core of Greenland
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-ze
Dark Magic Rabbit
A magician spins a black top hat to show their audience it’s empty. Then, with the wave of a wand and a few magic words, PRESTO: a snow white rabbit pokes its ears over the brim. Compared to sawing a person in half, pulling a rabbit out of
The Bee’s Sneeze: Why allergies are getting worse
Allergies have been documented in historical records dating as far back as 2,400 years ago, when Hippocrates wrote about “hostile humors” in some people who suffered badly after eating cheese. But why do we experience them to begin with? Wh
Venom and the cure
Venom is full of dualities. According to the UN’s World Health Organization, snakebite envenoming causes somewhere between 81,000 and 138,000 deaths per year, and even that is likely an undercount. Yet research into venom has yielded treatm
Tasting the forbidden fruit
A few months ago we got an email from a listener who tried a bit of a very poisonous apple and lived to tell the tale. Ultimately, he was fine, but the incident left him full of questions. We figured, why not run with that curiosity? We put
The Final Days of Sgt. Tibbs
Sgt. Tibbs, a fluffy, 19-year-old Maine Coon with tiger stripes, soft eyes, and a chipped tooth, is missing on the streets of Manchester, New Hampshire. His owner, Rose, fears the worst. But when she finds out her cat was never missing at a
The Emerald Forest: Why Irish farmers aren’t happy about some American trees
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 pl
