There’s a lost continent waiting to be explored, and it’s right below our feet. We’ll dig into the deep human relationship to the underground—and why we understand it from an instinctive point of view, but not so much from a physical one. (Hint: We’re afraid of the dark.) In an episode originally published November 2021, National Geographic photographer Tamara Merino will take us subterranean in Utah, Australia, and Spain, where modern-day cave dwellers teach us how to escape the heat.

In Vietnam photojournalist and National Geographic Explorer Martin Edström created 360 images of the world’s largest cave, Son Doong. It’s so big that a forest grows inside of it. Ever zip-line to a remote island? Cartographers did, 30 miles west of San Francisco. What did they see when they mapped the hard-to-reach landform known as the Farallon Islands? Caves. China is home to some of the most intricate cave systems on the planet. These explorers used a laser scanner to capture never before seen images of undocumented caves.

For decades, the U.S. government evangelized fire suppression, most famously through Smokey Bear’s wildfire prevention campaign. But as climate change continues to exacerbate wildfire seasons and a growing body of scientific research supports using fire to fight fire, Indigenous groups in the Klamath Basin are reviving cultural burning practices that effectively controlled forest fires for centuries. In an episode originally published June 2022, National Geographic photographer Kiliii Yüyan introduces us to people bringing back this cultural practice and teaching the next generation how to use fire.

National Geographic Explorer Tara Roberts is inspired by the stories of the Clotilda, a ship that illegally arrived in Mobile, Alabama, in 1860, and of Africatown, created by those on the vessel—a community that still exists today. The archaeologists and divers leading the search for the Clotilda lay out the steps it took to find it. In this last episode of the Into the Depths podcast, which published in March 2022, Tara talks to the living descendants of those aboard the ship. She admires their enormous pride in knowing their ancestry, and wonders if she can trace her own ancestors back to a ship. She hires a genealogist and visits her family’s small hometown in North Carolina. The surprising results bring a sense of belonging to a place that she never could have imagined. Want more?

Sound on! From conch shells to bone flutes, humans have been making musical instruments for tens of thousands of years. What did prehistoric music sound like?

When Nat Geo Explorer Gibbs Kuguru was in college, he found himself trying to choose between two terrifying futures: going free diving with sharks off the coast of South Africa or, even scarier, studying for the MCAT. Since then, he’s become devoted to sharks. His genetic research has shown they can do remarkable things, like change color to become more effective predators. And he’s also become a staunch advocate for shark species as they grow more vulnerable to overfishing and the effects of climate change.

When India and Pakistan gained their independence from Britain, a border was drawn between the two new countries. The split started a chain reaction of violence that led to one of the largest forced migrations in human history. More than 1 million people died in the tragedy.

Are we alone in the universe? It’s a question we’ve been asking for millennia. Now we’re on the cusp of learning the answer. Frank Drake—one of the most vocal (and brilliant) askers—has spent the past six decades inspiring others to join him in this quest. Now, a new generation of scientists is carrying his work forward. They’re finally being taken seriously, and they’re about to change the way we think about our place in the cosmos. For more information on this episode, visit natgeo.com/overheard. Want more?

Meet Kari. Now meet the other Kari. One played college lacrosse in the 1980s; the other currently plays at the same school for the same coach. College sports have radically evolved during that time—take the high-tech clothes that emit infrared radiation to maximize performance—but there’s one constant: Title IX of the Higher Education Act ensures that no person is excluded from university programs “on the basis of sex.” In collaboration with ESPN and The Walt Disney Company, we examine how Title IX continues to ripple across American society. For more information on this episode, visit natgeo.com/overheard. Want more?

For decades, the U.S. government evangelized fire suppression, most famously through Smokey Bear’s wildfire prevention campaign. But as climate change continues to exacerbate wildfire seasons and a growing body of scientific research supports using fire to fight fire, Indigenous groups in the Klamath Basin are reviving cultural burning practices that effectively controlled forest fires for centuries. National Geographic photographer Kiliii Yüyan introduces us to people bringing back this cultural practice and teaching the next generation how to use fire. SHOW NOTES Want more?

“All roads lead to Rome” was once more than a saying; it was a fact. The first of the great roads of ancient Rome, the Appian Way was the most important of them all. Italians still travel what’s left of the Queen of Roads, even if they don’t always know it. National Geographic writer Nina Strochlic and photographer Andrea Frazzetta take us on an immersive trip down the venerable road. The soundscapes they travel through—the voices and vibrations of modern and ancient life—reveal something essential about the Italian identity. For more information on this episode, visit natgeo.com/overheard. Want more? So, how did the Romans build 200,000 miles of roads? It wasn’t easy. You’ll find out more here in an issue of National Geographic History. St. Peter fled Rome, so the story goes, along the Appian Way. As he left, he encountered Jesus Christ—resurrected. There is still a church on that site, aptly named Domine Quo Vadis, for the famous phrase St. Peter uttered before he returned to Rome and was crucified himself. You can see Annibale Carracci’s 17th-century painting of the event here. If going underground and being surrounded by bones doesn’t give you the willies, then you’ll love visiting the catacombs in Italy. Or you can take a look here, and read about why Romans buried their dead this way.

Social media is not just for modern folk.

For more information on this episode, visit nationalgeographic.com/overheard Want more? The new book Lost Cities, Ancient Tombs: A History of the World in 100 Discoveries details the story of Pompeii and other milestones in the human journey. Pompeii is not just an archaeological site; it's one huge graveyard. But it was very much a living city right up until it was snuffed out by Mt. Vesuvius. When you think of an avalanche, you probably think of snow. But volcanoes also cause avalanches. Archaeologists believe that it was an avalanche of rocketing, boiling gas and sediment that cooked Pompeiians alive in 79 A.D. In the late 1800s, archaeologists started pouring plaster into voids left in the hardened volcanic ash covering Pompeii. The result? Full-sized casts of Vesuvius' victims—human and otherwise. Do you live in the shadow of a volcano? Here are a few safety tips for when that telltale rumbling begins. Could Chernobyl be our contemporary version of Pompeii? Some archaeologists think so. Also explore: Curious about how Pompeii's graffiti compares to the stuff in your own backyard? Check out images of ancient Pompeiian graffiti at the Ancient Graffiti Project.

San Diego is home to the world’s first frozen zoo—a genetic library where scientists are racing to bank the tissues and stem cells of disappearing animals.

How did the planets form? How did life happen? Where did Earth’s water come from? To answer questions like these, scientists used to go big—looking at planets, dwarf planets, and moons—but now small is the new big. Technology is zooming in on the pint-size stuff—asteroids, comets, meteors, and other chunks of space rock—that couldn’t be studied before, and Lucy, a spacecraft designed to visit eight asteroids near Jupiter, is poised to learn how the secrets inside these small bodies are reshaping ideas about the big old solar system.

Trees provide much-needed shade for urban Americans on a hot day, but not everyone gets to enjoy it. New research illuminates how decades of U.S. housing policy created cities where prosperous, white neighborhoods are more likely to be lush, and low-income communities of color have little respite from the sun. National Geographic writer Alejandra Borunda explains how activists are trying to make Los Angeles greener and healthier for everyone, and why the solution isn’t just to plant more trees. For more information on this episode, visit natgeo.com/overheard Want more? Research shows how racist housing practices created oppressively hot neighborhoods.
