Nell Greenfieldboyce

Nell Greenfieldboyce joined NPR News in January 2005 to cover the media organization's newly created technology beat for NPR's science desk. The Johns Hopkins alumna has reported on topics such as pet cloning, gene therapy, ballistics, and federal laws surrounding new technology. Her primary interest is researching how applied science and technology connects with people and culture.

Greenfieldboyce's features can currently be heard on Morning Edition and All Things Considered, but before her life at NPR she worked for magazines including U.S. News & World Report and New Scientist. After working in print for ten years, Greenfieldboyce is excited to explore the field of radio and the added effects sound can bring to a piece.

In addition to receiving her B.A. in social sciences and a M.A. in science writing from Johns Hopkins, Greenfieldboyce also taught science writing for four years at the university. Greenfieldboyce was honored for her talents with the Evert Clark/Seth Payne Award for Young Science Journalists.

Greenfieldboyce lives with her husband in Washington, D.C., and does a bit of rug-hooking in her free time, creating complicated geometric patterns out of burlap and scraps of wool.

 

Scientists can get very excited about what they study, and that means they can be pretty jazzed when what they study gets turned into one of the official emojis of the world and enters our shared visual language.

But sometimes that enthusiasm is tempered by more complex feelings, which is the case with some of the latest emojis that are about to hit our smartphones.

Consider the "rock" emoji.

NASA is at a critical juncture in its push to get people back to the moon by 2024, with key decisions expected within weeks.

This effort to meet an ambitious deadline set by the Trump administration last year faces widespread skepticism in the aerospace community, even as the new head of human spaceflight at NASA insists that it can succeed.

U.S. officials are weighing the benefits and risks of proposed experiments that might make a dangerous pathogen even worse — but the details of that review, and the exact nature of the experiments, aren't being released to the public.

Later this week, officials are to hold a meeting in Bethesda, Md., to debate how much information to openly share about this kind of controversial work and how much to reveal about the reasoning behind decisions to pursue or forgo it.

Some wolf puppies are unexpectedly willing to play fetch, according to scientists who saw young wolves retrieve a ball thrown by a stranger and bring it back at that person's urging.

This behavior wouldn't be surprising in a dog. But wolves are thought to be less responsive to human cues because they haven't gone through thousands of years of domestication.

Parrots can perform impressive feats of intelligence, and a new study suggests that some of these "feathered apes" may also practice acts of kindness.

African grey parrots voluntarily helped a partner get a food reward by giving the other bird a valuable metal token that could be exchanged for a walnut, according to a newly published report in the journal Current Biology.

Special fibers that change color when they are under strain have helped scientists come up with some simple rules that can predict how a knot will perform in the real world.

Shepherds in Christmas Nativity scenes that were painted, carved or sculpted hundreds of years ago sometimes have throats with large, abnormal growths.

These are realistic depictions of goiter, an enlargement of the thyroid gland caused by iodine deficiency. The condition was common in those days in northern Italy, where the soil and water are depleted of iodine.

An unprecedented mission to venture close to the sun has revealed a strange region of space filled with rapidly flipping magnetic fields and rogue plasma waves.

These surprises are among just some of the first observations by NASA's Parker Solar Probe, which blasted off last year to get up-close-and-personal with our nearest star.

Ublester Rodriguez could not have anticipated that his life would be profoundly changed by kitchen and bathroom countertops.

He says that he grew up poor, in a small Mexican town, and came to the United States when he was 14. He spoke no English, but he immediately got a job.

"In the beginning I was working in a Chinese restaurant, from 10 a.m. to 10 p.m. It was all day, so I never had time to go to school," he recalls. "I was a dishwasher."

Vampire bats might have a nasty reputation because of the way they ruthlessly drink their victims' blood, but these bloodthirsty beasts can be both generous and loyal when it comes to their fellow bats.

Captive common vampire bats will share their food with hungry bat companions, and forge such a bond that they continue to hang out with these buddies once they're released back to the wild, according to a newly published study in the journal Current Biology.
