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.

The Apollo 11 command module, which took the first moonwalkers to lunar orbit and back in 1969, is undergoing a painstaking restoration, in preparation for an unusual national tour later this year.

A study published Thursday shows how a bird flu virus that's sickening and killing people in China could mutate to potentially become more contagious.

Just three changes could be enough to do the trick, scientists report in the journal PLOS Pathogens.

And the news comes just as federal officials are getting ready to lift a moratorium on controversial lab experiments that would deliberately create flu viruses with mutations like these.

Scientists have found a shockingly hot, massive, Jupiter-like planet that has a tail like a comet.

"It is so hot that it is hotter than most stars that we know of out there," says Scott Gaudi of Ohio State University in Columbus, Ohio, whose team describes the scorching world called KELT-9b in the journal Nature.

Common blood tests for lead can give falsely-low results in certain cases, according to a new warning from the Food and Drug Administration.

The tests, manufactured by Magellan Diagnostics, are commonly used in doctors' offices and clinics, and on its website the company calls itself "the most trusted name in lead testing." But the FDA now says that its tests can give inaccurate results when used to test blood drawn from a vein.

The teeth of Tyrannosaurus rex have been called "killer bananas," and a new study in the journal Scientific Reports shows just how hard those fearsome chompers could clamp down.

"What we came up with were bite forces of around 8,000 pounds," says Gregory Erickson of Florida State University. "That's like setting three small cars on top of the jaws of a T. rex — that's basically what was pushing down."
