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.

Former research chimps owned by the National Institutes of Health should be moved from laboratories to retirement sanctuaries unless that relocation is "extremely likely" to shorten their lives, a report issued Friday says.

Kermit the Frog used to sing that it wasn't easy being green, but that isn't the case for some real-life lizards. They apparently find being green so easy that even their blood is green.

A study published Tuesday suggests seems that this lime-green blood has evolved independently several times in lizards.

Scientists are now trying to understand how these lizards might benefit from blood that's green. The answer could provide new insights into human illnesses like jaundice and malaria.

Ever since astronomers started to detect planets beyond our solar system, they've been trying to find another world just like Earth. And few years ago, they announced that they'd found a planet that was the closest match yet — Kepler-452b.

Trouble is, some astronomers now say it's not possible to know for sure that this planet actually exists.

If signs of life are found on a planet beyond our solar system sometime in the next decade, they'll most likely be on a planet discovered by a NASA satellite that's scheduled to launch on Monday.

Government health agencies have spent more than two decades shying away from gun violence research, but some say the new spending bill, signed by President Trump on Friday, will change that.

That is because, in agency instructions that accompany the bill, there is a sentence noting that the Centers for Disease Control and Prevention has the authority to conduct research on the causes of gun violence.
