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.

The largest research hospital in the world, the National Institutes of Health Clinical Center in Bethesda, Md., needs reform so that patient safety is always the priority — and never subservient to the demands of science.

The National Institutes of Health has suspended work in two facilities that manufacture products given to people who are enrolled in research studies, saying the facilities haven't complied with safety standards designed to protect already-sick people from inappropriate risks.

Finding a new planet that orbits a distant star isn't such a big deal anymore — astronomers have discovered around 2,000. But no one knows if any of these planets has a moon.

That might change this year, if a moon-hunting project goes as planned.

Scientists have discovered a supermassive black hole that may be the biggest ever spotted — and its location in a ho-hum group of galaxies suggests that cosmic monsters like this one might be more common than astronomers previously thought.

The Department of Labor is issuing a long-awaited and controversial rule Thursday aimed at better protecting workers from inhaling silica dust.

The new rule dramatically reduces the allowed exposure limits for workers in a slew of industries, from construction to manufacturing to fracking.
