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.

Fresh Allegations Leveled Against Polar Bear Scientist

The polar bear researcher who was suspended from his government job last month has received a new letter from investigators that lays out actions he took that are described as being "highly inappropriate" under the rules that apply to managing federal contracts.

According to the letter, wildlife biologist Charles Monnett told investigators that he assisted a scientist in preparing that scientist's proposal for a government contract. Monnett then served as chair of a committee that reviewed that proposal.

Polar Bear Scientist Faces New Questions

A wildlife biologist is continuing to face questions about an influential paper he wrote on apparently drowned polar bears, with government investigators reportedly asking whether he improperly steered a research contract to another scientist as a reward for reviewing that paper.

"They seem to be suggesting that there is some sort of conspiracy that involves global warming and back scratching that appears to be frankly just nuts," says Jeff Ruch, a lawyer with Public Employees for Environmental Responsibility.

Early Earth May Have Been Orbited By Two Moons

The early Earth had two moons instead of just one — our familiar moon, as well as a smaller companion moon that also rose and set in the sky for tens of millions of years.

That's according to a new theory that says this smaller moon eventually went careening into our moon and is still there, in the form of mountains on its far side.

Scientists have long puzzled over those mountains, and the fact that the two sides of our moon are very different. The near side has flat lowlands, while the far side is high and mountainous.
