The Problem With Superchickens

Tue, 23 Aug 2022 09:00:00 GMT

Scientists recently discovered a fascinating paradox: when they bred together superproductive, egg-laying hens, they found the chickens produced fewer eggs. We examine what went wrong with these so-called superchickens, and we look at human examples of this phenomenon—a high school Model UN team and a retail giant.

The Triumph and Tragedy of Indian Independence

Tue, 09 Aug 2022 09:00:00 GMT

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. Both countries are now approaching 75 years of independence, and the people who were there to remember it are reaching their twilight years. This may be our last chance to hear directly from the eyewitnesses who lived through the victory of independence and the subsequent tragedy of partition.

National Geographic Explorer Sparsh Ahuja has been documenting the stories of people who were forced from their homes during partition and is bringing them back to their ancestral home—if not in person then through virtual reality.

Frank Drake’s Cosmic Road Map

Tue, 02 Aug 2022 09:00:00 GMT

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.

Harnessing the Power of Yellowstone’s Supervolcano

Tue, 26 Jul 2022 09:00:00 GMT

If a major eruption ever were to occur at Yellowstone’s “supervolcano,” the event could destroy huge swaths of North America. But in recent years, some scientists have proposed that the amazing power locked beneath the caldera could be harnessed to generate renewable geothermal energy.

This Indigenous Practice Fights Fire with Fire

Tue, 14 Jun 2022 09:00:00 GMT

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.

Sonic Postcards From the Appian Way

Tue, 07 Jun 2022 09:00:00 GMT

“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.

You can see Annibale Carracci’s 17th-century painting of the event here.

Turning Old Cell Phones into Forest Guardians

Tue, 05 Apr 2022 09:00:00 GMT

What happens when a tree falls in a forest and no one is listening? The sound starts with truck engines and chainsaws and ends with a small piece of forest being silenced. Illegal logging is slowly thinning out the world’s forests, paving the way for widespread deforestation. With limited resources and difficult terrain, it’s a hard problem to tackle. National Geographic Explorer Topher White—who considers himself a war photographer for climate change—has found that by listening for the sounds of logging through hundreds of recycled cell phones nailed high in treetops from Indonesia to Eastern Europe, the stewards of the world's trees might have a chance to detect and prevent illegal logging.

Queens of the High Seas

Tue, 29 Mar 2022 09:00:00 GMT

Yo-ho, a pirate’s life for she! Legends of Blackbeard and movie buccaneers like Captain Jack Sparrow give us the impression that piracy was a man’s world. But historians and the Nat Geo book Pirate Queens: Dauntless Women Who Dared to Rule the High Seas are righting the ship. Join the fleet of Zheng Yi Sao, a woman from southern China who at her peak commanded some 70,000 pirates during the early 19th century.

First Ascent of a Sky Island

Tue, 22 Mar 2022 09:00:00 GMT

In the most remote part of Guyana, plateaus called tepuis—also known as sky islands for poking through the clouds—rise up from the jungle. They’re topped by unique ecosystems, filled with plants and animals never before seen by human eyes. That’s because getting there is no small feat. Eager to find new species but unable to scale the sheer cliff faces, 80-year-old biologist Bruce Means teamed up with professional climbers and Indigenous people to trek through the jungle and get to the top of an uncharted tepui named Weiassipu in search of frogs and adventure.

Nowruz and the Night Sky

Tue, 15 Mar 2022 09:00:00 GMT

Not everyone celebrates the New Year in the middle of winter; for 300 million people around the world, their New Year begins at the moment of the vernal equinox.

Amelia Earhart Part II: The Lady’s Legacy

Tue, 08 Mar 2022 10:00:00 GMT

Behind her modest smile and windblown charm, Amelia Earhart was a rarity in the 1930s: a fiercely confident woman with a dream to fly. Her adventurous spirit went well beyond setting records as a pilot—her true goal was perhaps equality for women. This is a different Amelia, which might explain why the mystery of her disappearance remains unsolved—explorers are looking in the wrong place.

Ever since Amelia Earhart made her last radio transmission somewhere over the Pacific, theories about her disappearance have proliferated; more than 80 years later, the constant retelling of her story shows no signs of slowing. Although the search to find a “smoking gun” has yielded little evidence, there are many who believe they know how Amelia’s story ended. Whether they’re right or wrong, one thing remains true: Their stories have little to do with Amelia herself.

Playback: The Battle for the Soul of Artificial Intelligence

Tue, 22 Feb 2022 10:00:00 GMT

With every breakthrough, computer scientists are pushing the boundaries of artificial intelligence (AI). We see it in everything from predictive text to facial recognition to mapping disease incidence. But increasingly machines show many of the same biases as humans, particularly with communities of color and vulnerable populations. In this episode, we learn how leading technologists are disrupting their own inventions to create a more humane AI.

In 2020 widespread use of medical masks has created a new niche—face-mask recognition. The technology would help local governments enforce mask mandates, but is it worth it?

Thanks to evolution, human faces are much more variable than other body parts. In the words of one researcher, “It's like evolving a name tag.”

Most people have difficulty accurately recognizing strangers. But a few individuals—called super-recognizers—excel at the task. London police have employed some of these people to help find criminal suspects.

Playback: If These Walls Could Talk

Tue, 05 Oct 2021 09:00:00 GMT

Social media is not just for modern folk. In this episode from the Overheard archives, we’ll look at how in ancient Pompeii, people also shared what they thought, who they met with, what they ate—just with different technology.

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.

Playback: The Frozen Zoo

Tue, 28 Sep 2021 09:00:00 GMT

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. As scientists begin to clone endangered species, we revisit an episode from our archives that delves into what conservation looks like, as we head into a period that some scientists believe is our next great extinction.

More information about Elizabeth Ann, the cloned black-footed ferret can be found here.

National Geographic photographer Ami Vitale has covered conflict and nature. She was with Sudan when he died and she believes that the survival of creatures like the northern white rhino is intertwined with our own.

Move over, Noah. Joel Sartore is building his own ark — out of photographs. He’s on a decades-long mission to take portraits of more than 15,000 endangered species before it’s too late.

Stuart Pimm has a lot more to say about species revival. In this editorial he makes a case against de-extinction — and explains why bringing back extinct creatures could do more harm than good.

It’s been a long time since Jurassic Park hit theatres. Today, our revival technology straddles the line between science fact and science fiction — but do we want to go there?

Read Kate Gammon’s original reporting for InsideScience, which inspired this conversation here at Overheard HQ.

Want to dive further into the debate? Hear George Church’s talk — and talks by some of the greatest minds in conservation — at the TedxDeExtinction conference.

The Frozen Zoo is working on a lot of exciting research that didn’t make it into the episode. For example, they’ve already managed to turn rhino skin cells into beating heart cells. To learn more about what they’re up to, check out the San Diego Zoo’s Institute for Conservation Research for yourself.

Some of the most promising applications for the Frozen Zoo come from new technology that lets us turn one kind of cell into any other kind of cell. Read more about the first mouse that was created from skin cells.

Lucy in the Sky With Asteroids

Tue, 24 Aug 2021 09:00:00 GMT

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.

Cooling Cities By Throwing Shade

Tue, 03 Aug 2021 09:00:00 GMT

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.

An Accidental Case of the Blues

Tue, 08 Dec 2020 10:00:00 GMT

Pigments color the world all around us, but where do those colors come from? Historically, they’ve come from crushed sea snails, beetles, and even ground-up mummies. But new pigments are still being discovered in unexpected places, and for researcher Mas Subramanian, a new color came, well, out of the blue. Overheard’s Amy Briggs ventured into the National Geographic photo studio to see the new color—the first blue pigment of its kind discovered since Thomas Jefferson was president.

The Strange Tail of Spinosaurus

Tue, 24 Nov 2020 10:00:00 GMT

Spinosaurus has long been a superstar among dinosaur fans, with its massive alligator-like body and a huge “sail” of skin running the length of its spine.

The Frozen Zoo

Tue, 10 Dec 2019 09:26:00 GMT

Right now, one million animal and plant species are threatened with extinction. Conservation scientists are doing whatever they can to save them, or at least of piece of them. For the last 45 years, a team of researchers at the San Diego Zoo has been freezing the cells of endangered animals. With these time capsules of DNA, researchers continue to study endangered animals, and hope to maybe even bring some back from the brink of extinction.

If These Walls Could Talk

Tue, 26 Nov 2019 10:10:00 GMT

Social Media is not just for modern folk. In ancient Pompeii, people also shared what they thought, who they met with, what they ate... It's just, they had to use different technology. For more information on this episode, visit nationalgeographic.com/overheard

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.

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.

March of the Beaver

Tue, 12 Nov 2019 09:31:00 GMT

The desolate Alaskan tundra - a landscape that has literally been frozen solid for thousands of years - is suddenly caving in on itself. Colonizing beavers are engineering new wetlands that thaw the soil, rapidly releasing greenhouse methane into the atmosphere. Beavers can survive in the arctic because - like people - they change the environment to make homes for themselves, and their carbon footprint can be seen from space.
