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.

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.

India's space agency says that four astronaut candidates have been selected for its first human mission, targeted to launch by 2022, but they've not been publicly named or identified.

India hopes to join the United States, Russia and China as the world's fourth nation capable of sending people to space. It has been developing its own crewed spacecraft, called Gaganyaan (or "sky vehicle" in Sanskrit), that would let two to three people orbit Earth on a weeklong spaceflight.

An enormous number of tumbleweeds blew onto a road in eastern Washington state on New Year's Eve, piling up into a mountain of tangled branches that blocked traffic and even buried some cars, trapping travelers inside.

"In the 20 years that I have worked here, I have never seen it as bad as this," says Washington State Patrol trooper Chris Thorson. "I've never seen six to eight cars, including a semi-truck, actually stopped and trapped on a highway because of tumbleweeds."

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.

Steamboat Geyser, the tallest active geyser in the world, erupted more times in 2019 than in any other year, baffling scientists who are trying to understand what triggered this unusual streak of activity.

The geyser can shoot water more than 300 feet into the air, and this year it has erupted more than 45 times, surpassing the 32 eruptions recorded in 2018.

The Department of Labor's workplace safety agency is getting ready to take new action to reduce workers' exposure to dangerous silica dust that can irreparably damage the lungs.

Every day, 20 to 30 trucks roll into a factory in Minnesota. They're filled with quartz — some of it like a powder, and some of it like sparkling little pebbles, in big white sacks.

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."
