Nell Greenfieldboyce

Correspondent, Science Desk

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.

Birds Got Their Colorful, Speckled Eggs From Dinosaurs

A new study found that birds' dinosaur relatives had eggs with traces of two pigments—a red-brown one and a blue-green one. In today's birds that might produce a color such as robin's egg blue.

A new analysis of what were initially thought to be microbial fossils in Greenland suggests they might instead just be mineral structures created when ancient tectonic forces squeezed stone. While most of the structures point in one direction, the red arrow shows that some point in the other direction. Courtesy of Abigail Allwood hide caption
