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.

Meat Mummies: How Ancient Egyptians Prepared Feasts For Afterlife

Anyone up for meat mummies? Above, a mummified beef rib from the tomb of Tjuiu, an Egyptian noblewoman, and her husband, the powerful courtier Yuya, circa 1386-1349 BC.

Meat mummies.

It's a word pairing that is, I dare say, pretty rare. Who among us has heard those two words together? What, indeed, could a "meat mummy" be?

A Rancher And A Conservationist Forge An Unlikely Alliance

Trout fishing is big business in Montana, bringing in tens of millions of dollars annually.

Trout fishing is a magnet that draws people from around the world to places like Ovando, Mont. Just ask the owner of Blackfoot Angler and Supplies, Kathy Schoendoerfer.

"Every state in the nation has been through this little shop in Ovando, Montana, population 50," says Schoendoerfer with a mix of pride and perhaps a little fatigue. "And we've also had everybody from Russia, Latvia. We get a lot of Canadians, France, Finland, Brazil, Scotland, Germany, South Africa. We get a lot of business out here. You know, fly-fishing is huge."

As Climate Warms American West, Iconic Trout In Jeopardy

Native Westslope cutthroat trout and bull trout swim in the cool waters of the Flathead River near Glacier National Park, Montana.

In the mountain streams of the American West, the trout rules. People don't just catch this fish; they honor it. And spend lots of money pursuing it.

But some western trout may be in trouble. Rivers and streams are getting warmer and there's often less water in them. Scientists suspect a changing climate is threatening this iconic fish.

I joined two such scientists from the U.S. Geological Survey as they drove up a mountain road in Montana, in the northern Rockies, a place dense with stands of Douglas fir and aspen trees and braided with mountain streams.

How'd They Do That? The Story Of A Giant Rock And A Road Of Ice

The Large Stone Carving is the heaviest stone in the Forbidden City in Beijing. It was believed to have weighed more than 300 tons when it was first transported to the site between 1407 and 1420.

Great works of ancient engineering, like the Pyramids or Stonehenge, inspire awe in every beholder. But some onlookers also get inspired to figure out exactly how these structures were made.

Howard Stone, an engineer from Princeton University, had such a moment in Beijing's Forbidden City — a city-within-a-city of palaces and temples built in the 15th and 16th centuries. A carved, 300-ton slab that formed a ramp to one structure particularly caught Stone's eye. "How in the world did it get here?" he wondered.

In Sandy's Wake, Flood Zones And Insurance Rates Re-Examined

When Sandy blew into East Coast communities a year ago, it was flooding that did the most damage.

That's in part because the average sea level has risen over the past century — about a foot along the mid-Atlantic coast. That made it easier for the storm to push the ocean onto the land.

And scientists say there will be many more Sandy-style storms — that is, torrential rain and wind that create heavy coastal flooding — and they'll be more frequent than in the past. But preparing people for that means changing the way they live, and that's proving politically difficult.

Fossil Find Points To A Streamlined Human Lineage

Researchers excavated the remains of five creatures who lived 1.8 million years ago, including this adult male skull. The excavation site, in Georgia in the former Soviet Union, was home to a remarkable cache of bones.

Fossils of human ancestors are rare. You could pile all the ones that scientists have found in the back of a pickup truck.

But a remarkable site in Georgia, in the former Soviet Union, has produced a rich group of bones dating back almost 2 million years — and the discovery is shaking the family tree of human evolution.

The fossil hunters found the cache of bones more than a decade ago in a place called Dmanisi, but kept most of the find under wraps.

Now, they've lifted the veil, revealing the fossilized remains of five creatures who lived 1.8 million years ago.

Trapped In A Fossil: Remnants Of A 46-Million-Year-Old Meal

A very old squished mosquito found in fossilized rock from Montana. Analysis of the insect's gut revealed telltale chemicals found in blood.

Scientists who study why species vanish are increasingly looking for ancient DNA. They find it easily enough in the movies; remember the mosquito blood in Jurassic Park that contained dinosaur DNA from the bug's last bite? But in real life, scientists haven't turned up multi-million-year-old DNA in any useable form.

Fortunately, a team at the Smithsonian Institution has now found something unique in a 46-million-year-old, fossilized mosquito — not DNA, but the chemical remains of the insect's last bloody meal.

Flood Forensics: Why Colorado's Floods Were So Destructive

Flooding brought down a house in Jamestown, Colo., on Sept. 18.

Parts of Colorado are still drying out after floods hit the state last month. Eight people died, and damage from the worst flooding in decades is in the hundreds of millions of dollars.

Scientists are now venturing into the hardest-hit areas to do a sort of "flood forensics" to understand why the floods were so bad.

Geologist Jonathan Godt takes Peak Highway in northern Colorado up into the Rockies. The road there winds past ravines and streams where water is still rushing.

After Disasters, DNA Science Is Helpful, But Often Too Pricey

Human DNA is the ultimate fingerprint. A single hair can contain enough information to determine someone's identity — a feature that's been invaluable for identifying the unnamed casualties of natural disasters and war. But forensic scientists who use DNA say the technology isn't always available where it's most needed, like in poor countries, or in war zones like Syria.

'Rivers On Rolaids': How Acid Rain Is Changing Waterways

Originally published on Fri September 13, 2013 8:47 am

Something peculiar is happening to rivers and streams in large parts of the United States — the water's chemistry is changing. Scientists have found dozens of waterways that are becoming more alkaline. Alkaline is the opposite of acidic — think baking soda or Rolaids.

Research published in the current issue of Environmental Science and Technology shows this trend to be surprisingly widespread, with possibly harmful consequences.

What's especially odd about the finding is its cause: It seems that acid rain actually has been causing waterways to grow more alkaline.
