Nell Greenfieldboyce

Nell Greenfieldboyce is a NPR science correspondent.

With reporting focused on general science, NASA, and the intersection between technology and society, Greenfieldboyce has been on the science desk's technology beat since she joined NPR in 2005.

In that time Greenfieldboyce has reported on topics including the narwhals in Greenland, the ending of the space shuttle program, and the reasons why independent truckers don't want electronic tracking in their cabs.

Much of Greenfieldboyce's reporting reflects an interest in discovering how applied science and technology connects with people and culture. She has worked on stories spanning issues such as pet cloning, gene therapy, ballistics, and federal regulation of new technology.

Prior to NPR, Greenfieldboyce spent a decade working in print, mostly magazines including U.S. News & World Report and New Scientist.

A graduate of Johns Hopkins, earning her Bachelor's of Arts degree in social sciences and a Master's of Arts degree in science writing, Greenfieldboyce taught science writing for four years at the university. She was honored for her talents with the Evert Clark/Seth Payne Award for Young Science Journalists.

A scientist whose observations of drowned polar bears raised alarms about climate change has received $100,000 to settle a whistle-blower complaint against an agency of the Department of the Interior.

Under the settlement, wildlife researcher Charles Monnett retired from his job at the federal Bureau of Ocean Energy Management on Nov. 15, and the agency agreed to remove a letter of reprimand that officials had placed in his file.

Evolution is relentless process that seems to keep going and going, even when creatures live in a stable, unchanging world.

That's the latest surprise from a unique experiment that's been underway for more than a quarter-century.

Scientists have used some new tricks and old dogs to show that thousands of years ago, wolves may have first become man's best friend in Europe.

Researchers extracted DNA from ancient wolf or dog fossils and compared it with DNA from modern dog breeds and wolves. Until recently, labs didn't have the kind of genetic tools they'd need to work with such old dog DNA and do this kind of detailed comparison.

Galaxy Quest: Just How Many Earth-Like Planets Are Out There?

A team of planet hunters estimates that about 22 percent of the sun-like stars in our galaxy may have planets about the size of Earth that are bathed in similar amounts of sunlight — and potentially habitable.

That's the conclusion of a new analysis of observations taken by NASA's Kepler Space Telescope, which was launched in 2009 to hunt for potentially habitable Earth-like planets around other stars.

The Tail's The Tell: Dog Wags Can Mean Friend Or Foe

Originally published on Fri November 1, 2013 10:41 am

Friend Or Foe? Scientists say dogs react differently to the direction of another dog's tail wag.

Dogs can pick up emotional cues from another dog by watching the direction of its wagging tail, a new study suggests.

In a series of lab experiments, dogs got anxious when they saw an image of a dog wagging its tail to its left side. But when they saw a dog wagging its tail to its right side, they stayed relaxed.
