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.

Sand From Fracking Could Pose Lung Disease Risk To Workers

A worker stands on top of a storage bin on July 27, 2011, at a drilling operation in Claysville, Pa. The dust is from powder mixed with water for hydraulic fracturing.

When workplace safety expert Eric Esswein got a chance to see fracking in action not too long ago, what he noticed was all the dust.

It was coming off big machines used to haul around huge loads of sand. The sand is a critical part of the hydraulic fracturing method of oil and gas extraction. After workers drill down into rock, they create fractures in that rock by pumping in a mixture of water, chemicals and sand. The sand keeps the cracks propped open so that oil and gas are released.

Feds Set New Rules For Controversial Bird Flu Research

Health officials around the world are on constant lookout for the deadly bird flu. Here a worker collects chickens on a farm in Kathamndu, Nepal, where the virus was suspected of infecting poultry last October.

Close Shave: Asteroid To Buzz Earth Next Week

An asteroid the size of an office building will zoom close by Earth next week, but it's not on a collision course, NASA says.

Still, some people think this near-miss should serve as a wake-up call.

"It's a warning shot across our bow that we are flying around the solar system in a shooting gallery," says Ed Lu, a former astronaut and head of the B612 Foundation, a nonprofit dedicated to protecting humanity from asteroids.

The asteroid known as 2012 DA14 was first spotted last year by astronomers in Spain. It's thought to be about 150 feet across and made of rock.

Silica Rule Changes Delayed While Workers Face Health Risks

Scientists Put An End To Moratorium On Bird Flu Research

Controversial experiments on bird flu could resume within weeks because leading influenza researchers around the world have finally called a halt to an unusual moratorium that has lasted more than a year.

The voluntary pause in the research started back in January 2012. Scientists had genetically altered the bird flu virus H5N1, changing it in ways that allowed it to spread through the coughs and sneezes of ferrets — the lab stand-in for people.
