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.

An Arbor Embolism? Why Trees Die In Drought

A forest near Trieste, Italy, is largely dead owing to drought stress during the summer of 2012.

Scientists who study forests say they've discovered something disturbing about the way prolonged drought affects trees.

It has to do with the way trees drink. They don't do it the way we do — they suck water up from the ground all the way to their leaves, through a bundle of channels in a part of the trunk called the xylem. The bundles are like blood vessels.

When drought dries out the soil, a tree has to suck harder. And that can actually be dangerous, because sucking harder increases the risk of drawing air bubbles into the tree's plumbing.

A 'Green' Gold Rush? Calif. Firm Turns Trash To Gas

Energy Of The Future? California company Sierra Energy is testing out a reactor that turns garbage — like these wood chips, metal fragments and plastics — into synthetic gas that can then be turned into a low-carbon diesel fuel.

California starts the ball rolling Wednesday on a controversial scheme to keep the planet from overheating. Businesses will have to get a permit if they emit greenhouse gases.

Some permits will be auctioned today; the rest are free. The big idea here is the state is putting a ceiling on emissions.

It's a gamble. And for this top-down climate plan to work, it has to usher in a greener, more efficient economy.

Calif. To Begin Rationing Greenhouse Gas Emissions

California begins a new plan to ration greenhouse gas emissions from large companies on Wednesday. Big companies must limit the greenhouse gases they emit and get permits for those emissions.

California begins a controversial experiment to curb climate change on Wednesday: The state will start rationing the amount of greenhouse gases companies can emit.

It's the most ambitious effort to control climate change in the country. Some say the plan will cost dearly; supporters say it's the route to a cleaner economy.

Here's how the climate deal works. Big companies must limit the greenhouse gases they emit — from smokestacks to tailpipes — and they have to get permits for those emissions. The clock starts Jan. 1.

Fixing NYC's Underground Power Grid Is No Easy Task

The fury of the great storm Sandy shocked a lot of people, like John Miksad, vice president of the New York electric utility Consolidated Edison. "We hit 14-foot tides — that was the biggest surprise," he told a press conference this week. "The water just kept rising and rising and rising."

That rising water flooded streets, buildings and parts of the city's underground electricity grid. Hundreds of thousands of New Yorkers lost power. But it might have been worse if the power lines had not been underground.

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

This image, from an archival video, shows the white whale NOC swimming around and under researchers' boats.

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 12:11 pm

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.
