Christopher Joyce

Christopher Joyce is a correspondent on the science desk at NPR. His stories can be heard on all of NPR's news programs, including NPR's Morning Edition, All Things Considered, and Weekend Edition.

Joyce seeks out stories in some of the world's most inaccessible places. He has reported from remote villages in the Amazon and Central American rainforests, Tibetan outposts in the mountains of western China, and the bottom of an abandoned copper mine in Michigan's Upper Peninsula. Over the course of his career, Joyce has written stories about volcanoes, hurricanes, human evolution, tagging giant blue-fin tuna, climate change, wars in Kosovo and Iraq and the artificial insemination of an African elephant.

For several years, Joyce was an editor and correspondent for NPR's Radio Expeditions, a documentary program on natural history and disappearing cultures produced in collaboration with the National Geographic Society that was heard frequently on Morning Edition.

Joyce came to NPR in 1993 as a part-time editor while finishing a book about tropical rainforests and, as he says, "I just fell in love with radio." For two years, Joyce worked on NPR's national desk and was responsible for NPR's Western coverage. But his interest in science and technology soon launched him into parallel work on NPR's science desk.

In addition, Joyce has written two non-fiction books on scientific topics for the popular market: Witnesses from the Grave: The Stories Bones Tell (with co-author Eric Stover); and Earthly Goods: Medicine-Hunting in the Rainforest.

Before coming to NPR, Joyce worked for ten years as the U.S. correspondent and editor for the British weekly magazine New Scientist.

Joyce's stories on forensic investigations into the massacres in Kosovo and Bosnia were part of NPR's war coverage that won a 1999 Overseas Press Club award. He was part of the Radio Expeditions reporting and editing team that won the 2001 Alfred I. duPont-Columbia University journalism award and the 2001 Sigma Delta Chi award from the Society of Professional Journalists. Joyce won the 2001 American Association for the Advancement of Science excellence in journalism award.

Hey, Sexy Dino, Show Me Your Feathers

This artistic interpretation shows an adult and juvenile feathered ornithomimid dinosaurs.

Some of the weirdest animal behavior is about romance. That's especially true with birds — they croon or dance or display brilliant feathers to seduce the reluctant.

This sort of sexual display apparently has a long pedigree: There's now new evidence that some dinosaurs may have used the same come-on.

The source is a kind of dinosaur that was built like a 400-pound ostrich. It lived about 75 million years ago and is called ornithomimus, meaning "bird mimic."

When Fire Met Meat, The Brains Of Early Humans Grew Bigger

If you're reading this blog, you're probably into food. Perhaps you're even one of those people whose world revolves around your Viking stove and who believes that cooking defines us as civilized creatures.

Well, on the latter part, you'd be right. At least according to some neuroscientists from Brazil.

Baby Beluga, Swim So Wild And Sing For Me

Whales are among the great communicators of the animal world. They produce all sorts of sounds: squeaks, whistles and even epic arias worthy of an opera house.

And one whale in particular has apparently done something that's never been documented before: He imitated human speech.

The beluga, or white whale, is smallish as whales go and very cute, if you're into marine mammals. Belugas are called the "canaries of the sea" because they're very vocal.

Scientists Solve Mystery Of Disappearing Salt Marshes

Originally published on Thu October 18, 2012 11:11 am

DAVID GREENE, HOST:

Let's pay a visit now to one of the crucial parts of our country's ecosystem. Along U.S. coastlines, there are salt marshes that serve as nurseries for fish, crabs and other shellfish. They also protect coastal areas against flooding. Scientists warn that some salt marshes are disintegrating, and researchers have a pretty surprising theory about why that is. Here's NPR's Christopher Joyce.

Few things are as rare as a piece of rock that falls from outer space and crashes onto Earth.

Among the most prized of these meteorites are from Mars. Friday, scientists describe the latest one discovered: It's called Tissint, and this weekend you can buy a piece of it.

AUDIE CORNISH, HOST:

And now to one more rare thing that came from space: a meteorite. Some of the most unusual and prized meteorites fell to Earth from Mars. In a new journal article, scientists describe the latest one that was discovered, and this weekend, you can buy a piece of it. NPR's Christopher Joyce has this story of a journey from Mars to a Manhattan auction house.

CHRISTOPHER JOYCE, BYLINE: The meteorite is called Tissint, and it contains a unique story about Mars.

Software Calculates City-Specific Carbon Footprint

Bedrich Benes and Michel Abdul-Massih

Originally published on Thu October 11, 2012 2:58 pm

One way to measure greenhouse gases is simply to capture them at the source: You put an instrument on a smokestack, for example. Cities, however, are full of cars, buses, factories and homes that all use fuel or electricity. No one really knows how much carbon dioxide, the main greenhouse gas, comes from each.

Ecologist Kevin Gurney says he can find out.

Hungry Snakes Trap Guam In Spidery Web

Invasive brown tree snakes have gobbled up most of Guam's native forest birds. Without these avian predators to keep their numbers in check, the island's spider population has exploded.

The Pacific Island of Guam is experiencing a population explosion — of spiders.

There are more spiders there now than anyone can remember. To get a sense of how weird the situation is, I started out in Maryland. On my front porch, overlooking the Severn River.

At 6:30 in the morning on a cool fall day, I find two spider webs in a matter of five minutes. But if I were on the island of Guam, I might find 70 or 80 spider webs in five minutes.

What Drove Early Man Across Globe? Climate Change

Anthropologists believe early humans evolved in Africa and then moved out from there in successive waves. However, what drove their migrations has been a matter of conjecture.

One new explanation is climate change.

Anthropologist Anders Erikkson of Cambridge University in England says the first few hardy humans who left Africa might've gone earlier but couldn't. Northeastern Africa — the only route to Asia and beyond — was literally a no man's land.

A Berry So Shiny, It's Irresistible (And Inedible)

The shiny blue berries of the tropical Pollia condensata plant rely on their looks, not nutritional content, to attract birds to spread their seeds.

That fake fruit in the wooden bowls that hotels love to decorate their lobbies with never looks quite right. No, apparently it takes nature to make a fake that looks even better than the real thing.
