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.

Mayan Artwork Uncovered In A Guatemalan Forest

Conservator Angelyn Bass cleans and stabilizes the surface of a wall of a Mayan house that dates to the ninth century. The figure of a man who may have been the town scribe appears on the wall to her left.

Archaeologists working in one of the most impenetrable rain forests in Guatemala have stumbled on a remarkable discovery: a room full of wall paintings and numerical calculations.

The buried room apparently was a workshop used by scribes or astronomers working for a Mayan king. The paintings depict the king and members of his court. The numbers mark important periods in the Mayan calendar.

'Wired To Run': Runner's High May Have Been Evolutionary Advantage

Researchers say our brains are probably wired from an evolutionary sense to encourage running and high aerobic activities. Above, a man runs past the Sydney Harbour Bridge on April 22.

Endurance athletes sometimes say they're "addicted" to exercise. In fact, scientists have shown that rhythmic, continuous exercise — aerobic exercise — can in fact produce narcoticlike chemicals in the body.

Now researchers suggest that those chemicals may have helped turn humans, as well as other animals, into long-distance runners.

The man behind the research is University of Arizona anthropologist David Raichlen, a runner himself. He does about 25 miles a week.

Fossil-hunting scientists are coming to grips with a new discovery that could change forever how we think of dinosaurs. What they've found is that dinosaurs may well have been tortured by large, flealike bloodsucking insects.

Yes, it appears that the greatest predators that ever roamed Earth suffered just as we mammals did — and as we still do. Fleas were thought to have evolved along with mammals — they like our soft skins and a diet of warm blood.

Scientists Link Rise In Quakes To Wastewater Wells

Originally published on Fri April 13, 2012 9:22 am

Scientists who watch for earthquakes have discovered a big increase in the number of small quakes in the middle of the country. It's an area that's usually pretty quiet geologically.

The scientists suspect the quakes are caused by wastewater wells. They plan to discuss their findings later this month at a seismology conference, but they've shared the basics with NPR.

Bill Ellsworth, a seismologist at the U.S. Geological Survey, says new technology over the past decade has given scientists a much better feel for when the Earth shakes.

Quakes Caused By Waste From Gas Wells, Study Finds

David Gilkey NPR

The U.S. Geological Survey will soon confirm that the oil and gas industry is creating earthquakes, and new data from the Midwest finds that these man-made quakes are happening more often than originally thought.

Earthquakes happen when faults in the Earth slip and slide against each other. There's continuous stress on innumerable faults on our continent, but seismologists like Bill Ellsworth, from the U.S. Geological Survey, started seeing something odd about 12 years ago.
