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.

Double-Blind Violin Test: Can You Pick The Strad?

In a double-blind test by professional violinists, most couldn't determine β€” by sound alone β€” which violin was an original Stradivarius and which was a modern instrument. Above, a 1729 Stradivari known as the "Solomon, Ex-Lambert."

In the world of violins, the names Stradivari and Guarneri are sacred. For three centuries, violin-makers and scientists have studied the instruments made by these Italian craftsmen. So far no one has figured out what makes their sound different. But a new study now suggests maybe they aren't so different after all.

OK, here's a test. Clip one is a musical phrase from Tchaikovsky's Violin Concerto in D Major. Clip two is the same phrase. The same musician plays both. But one is on a Stradivarius violin, the other on a violin made in 1980. See if you can tell the difference.

Endangered Turtle Survives Trans-Atlantic Journey

A Kemp's ridley sea turtle like this one traveled 4,600 miles across the Atlantic ocean in 2008. After being rehabilitated in Portugal, it is being reintroduced into its native Gulf of Mexico waters on Tuesday.

On Florida's Gulf coast Tuesday, there will be a celebrated homecoming. For a turtle. This is no ordinary turtle: Known as Johnny Vasco da Gama, after the 15th-century Portuguese explorer, it crossed the Atlantic twice β€” by sea and by air.

Johnny, as his human friends call him, is a critically endangered Kemp's ridley turtle. Only a few thousand of these sea-turtles exist, mostly in the Gulf of Mexico. Normally, they do not migrate across the Atlantic.

After Fukushima: A Changing Climate For Nuclear

The crippled Fukushima Dai-ichi nuclear power station is seen through a bus window on Nov. 12. The four reactors that failed were stabilized this month.

This year has something unpleasant in common with the years 1979 and 1986. In 1979, a nuclear reactor at Three Mile Island in Pennsylvania melted down. In 1986, the Soviet reactor at Chernobyl blew up and burned.

This year's meltdown occurred in Fukushima in Japan, and nuclear power isn't likely to be the same as a result.

Nuclear power had enjoyed 25 years of relative quiet, but the Fukushima accident reminded people that despite improvements in safety, nuclear plants could still go horribly wrong.

For some, though, nothing has changed much.

Turbulence As Europe Passes Fee On Plane Emissions

Air travel contributes only 2 to 4 percent of carbon dioxide emissions worldwide. A new ruling says airlines flying into an out of European airports will have to pay a price for the carbon dioxide they emit from burning jet fuel. Above, a plane takes off from the Geneva airport on March 11, 2010.

A European court ruled Wednesday that airlines flying into and out of European airports will have to pay a price for the carbon dioxide they emit when they burn jet fuel.

U.S. airlines, which had been fighting the idea in court, say the European Union is trying to force other countries to reduce carbon emissions. Europe currently limits carbon dioxide emissions from its major industries to curb global warming. The ruling cannot be appealed, and the decision likely to end the dispute.

U.S. Nuclear Agency Suffers Leadership Meltdown

The government organization charged with keeping nuclear power safe is having a meltdown. The Nuclear Regulatory Commission consists of five commissioners who direct the work of hundreds of nuclear engineers and other experts. They write the rules for how nuclear reactors operate.

Now four of those commissioners say the chairman of the NRC is a bully who's destroying their ability to do their job.

Climate Activists: To Cut Emissions, Focus On Forests

The world's forests act as massive sponges, sucking carbon from the atmosphere. Above, an aerial photo from 2009 shows massive deforestation in the Brazilian state of Para.

Some climate strategists are looking beyond the United Nations and the idea of remaking the energy economy β€” and toward the world's tropical forests.

The basic idea is to provide rich countries that emit lots of climate-warming gases another way to reduce their carbon footprint besides replacing or retrofitting factories and power plants. Instead, they could just pay poorer countries to keep their forests, or even expand them. Forests suck carbon out of the atmosphere. It's like paying someone to put carbon in a storehouse.

Grass Mattress Was A Stone Age Bed And Breakfast

Christopher Miller samples sediments from an excavation site in South Africa. Archaeologists found layers upon layers of burned bedding material, indicating that the hunter-gatherers who lived here 77,000 years ago stayed for a long time.

In archaeology, you get special bragging rights when you can lay claim to the oldest specimen of something.

Scientists in South Africa may now qualify for what they say is the world's oldest bed. Well, not a bed exactly, but more like a mattress made of grass.

What Lyn Wadley, an archaeologist at the University of Witswatersrand, found were mats of grass and sedge piled half an inch thick on the floor of a cavelike rock shelter in South Africa.

Can 'Carbon Ranching' Offset Emissions In Calif.?

Tall grasses in the San Joaquin valley in California suck carbon dioxide out of the air and store it in the soil. It's one option that environmentalists are pursuing for greenhouse gas "offsets" that can be bought and sold in the state.
Christopher Joyce NPR

Second of a two-part series on California's climate policies. Read part 1.

Climate experts are exploring the concept of growing dense fields of weeds to help soak up carbon dioxide from the atmosphere.

Just over a year from now, California will begin enforcing a set of laws that limit emissions of greenhouse gases from factories, power plants and, eventually, from vehicles.
