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.

Scientists have found a "new" horned dinosaur that lived about 79 million years ago — and they say the discovery helps them understand the early evolution of the family that includes Triceratops.

The new dinosaur, which was named Wendiceratops pinhornensis after a famous fossil hunter who discovered the bone bed in Canada where these fossils were buried, is one of the oldest known horned dinosaurs.

Scientists say they've found a bit of DNA in woolly mammoths that could help explain how these huge beasts were so well-adapted to live in the cold of the last ice age.

Woolly mammoths had long shaggy fur, small tails and ears to minimize frostbite, and a lot of fat to help stay warm as they roamed the tundra more than 12,000 years ago.

When giant icebergs break off of huge, fast-moving glaciers, they essentially push back on those rivers of ice and temporarily reverse the flow.

That's according to a new study of "glacial earthquakes," an unusual kind of temblor discovered just over a decade ago.
