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 around the United States are getting ready to do an unprecedented experiment: They plan to march en masse in Washington, D.C., and other cities on April 22, to take a stand for the importance of public policies based on science.

Some researchers predict that this March for Science will release much needed energy and enthusiasm at a time when science is under threat; others worry it will damage science's reputation as an unbiased seeker of truth.

A small, faint star relatively close by is home to seven Earth-size planets with conditions that could be right for liquid water and maybe even life.

The discovery sets a record for both the most Earth-size planets and the most potentially habitable planets ever discovered around a single star.

When you praise a dog, it's listening not just to the words you say but also how you say them.

That might not be huge news to dog owners. But now scientists have explored this phenomenon by using an imaging machine to peek inside the brains of 13 dogs as they listened to their trainer's voice.
