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.

Underwater Meadows Might Serve As Antacid For Acid Seas

Originally published on Tue July 15, 2014 12:45 pm

UC Santa Barbara's Jay Lunden and Andrew Brinkman, a summer intern for NOAA, prepare to deploy an instrument that measures temperature and salinity throughout the water column, and collects water samples.

The world's oceans are changing — chemically changing. As people put more carbon dioxide into the atmosphere, the oceans absorb more of it, and that's making the water more acidic.

The effects are subtle in most places, but scientists say that if this continues, it could be a disaster for marine life.

Dance Of Human Evolution Was Herky-Jerky, Fossils Suggest

Originally published on Sat July 5, 2014 1:18 am

Our popular image of Homo erectus as the proto-guy who whose human-like traits all emerged at once needs overhauling, some anthropologists say.

A trio of anthropologists has decided it's time to rewrite the story of human evolution.

That narrative has always been a work in progress, because almost every time scientists dig up a new fossil bone or a stone tool, it adds a new twist to the story. Discoveries lead to new arguments over the details of how we became who we are.

Maybe Dinosaurs Were A Coldblooded, Warmblooded Mix

Originally published on Thu June 26, 2014 5:23 am

Being a bit coldblooded has its charms, scientists say. A mammal the size of a T. rex, for example, would have to eat constantly to feed its supercharged metabolism — and would probably starve.

If you go to a zoo on a cold day and watch the snakes, you'll see what it means to be coldblooded. Not much action going on — most reptiles and other coldblooded creatures take on the temperature of their surroundings, so they tend to be most sluggish when the outside temperature is cool. The monkeys, however, act like they've had one too many cappuccinos.

Spiders Tune In To Web's Music To Size Up Meals And Mates

Some of the toughest stuff in nature is spider silk — as strong, ounce for ounce, as nylon. And a silk web makes a great trap for prey, as well as a nice place for a spider to live.

Scientists Find Africa's Longest Land Migration: Zebras' 350-Mile Trek

Originally published on Thu May 29, 2014 7:11 pm

Wildlife biologists have discovered the longest known terrestrial migration in Africa: some 350 miles across southern Africa by huge herds of zebras. Large mammal migration in Africa has generally been hindered by the subdivision and fencing of land. However, this one remains possible because it takes place in a unique, multi-country wildlife corridor.

Hybrid Trout Threaten Montana's Native Cutthroats

Many parts of the U.S. have been getting warmer over the past several decades, and also experiencing persistent drought. Wildlife often can't adjust. Among the species that are struggling is one of the American West's most highly prized fish — the cutthroat trout.

In springtime, you can find young cutthroats in the tiny streams of Montana's Shields Basin. Bend over and look closely and you might see a 2-inch fish wriggling out from under a submerged rock — the spawn of native cutthroats.

Scientists Discover Carbon Cycle Is Out Of Whack

Originally published on Thu May 22, 2014 9:39 am

Scientists who track carbon say the way it cycles from the atmosphere back to earth and into plants and animals has apparently changed. It could be the whole planetary carbon treadmill is speeding up.

In the spring of 2013, poachers looking for elephant ivory took advantage of the chaos of a civil war raging in the Central African Republic, and massacred 26 rare forest elephants at a special place called the "Dzanga bai."

Ivory poachers are killing some 22,000 African elephants a year. Among the recent casualties was a group of rare forest elephants in the Central African Republic.

Those elephants were featured in an NPR program, Radio Expeditions, in 2002, when former NPR host and correspondent Alex Chadwick and sound engineer Bill McQuay went to central Africa to record them.
