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.

On Election Day this November, about 1 in 4 Americans will vote using a device that never lets the voter see a copy of his or her vote on paper.

On Friday, the Rosetta spacecraft will smack into the icy surface of the comet 67P/Churyumov-Gerasimenko and go silent. Scientists with the historic mission are wondering how they'll feel as the orbiter makes its death-dive toward the comet that has been its traveling companion for more than two years.

Scientists have seen what might be plumes of water vapor erupting out of the icy surface of Jupiter's moon Europa, suggesting that its subsurface ocean could be probed without having to drill through miles of ice.

That's according to new findings from images captured by NASA's Hubble Space Telescope that were released Monday and that will be published this week in The Astrophysical Journal.

A mysterious glowing "blob" in outer space has puzzled astronomers for more than 15 years. Now, a team of researchers says it has uncovered the secret behind the blob's eerie light.

The blob was first spotted back in the late 1990s by Chuck Steidel, an astronomer at Caltech, and some colleagues. They were observing a bunch of galaxies in the distant reaches of the universe, he recalls, "but we also saw these big blotchy things."

NASA sent a robotic spacecraft from Florida out to an asteroid Thursday, but that's not the only asteroid mission the space agency has in the works.

Most populations of humpback whales no longer need endangered species protections, according to a decision by the National Marine Fisheries Service.

The U.S. government listed all humpback whales as endangered back in 1970, after commercial whaling had drastically reduced their numbers.

Lizards are expected to be hard hit by climate change — and a new study suggests it might be even worse for some lizards than scientists thought.

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.

A potentially habitable planet about the size of Earth is orbiting the star that is nearest our solar system, according to scientists who describe the find Wednesday in the journal Nature.

"The wave" has been a popular diversion among spectators at stadium sporting events since at least the early 1980s, and over the years this pastime has caught the attention of physicists.
