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.

Electric eels sometimes leap out of the water to increase the power of their jolt — and one scientist has been trying to understand this behavior more fully by letting a small eel repeatedly shock his arm.

Ken Catania, a Vanderbilt University neurobiologist who has been studying electric eels in his lab, recently noticed something strange whenever he tried to fish them out with a net that had a metal rim and handle. The eels would leap out of the water to attack it.

For years, the government has been trying to reduce the risk that legitimate biological research could be misused to threaten the public's health, but those efforts have serious shortcomings.

That's the conclusion of a report released Thursday by the prestigious National Academies of Sciences, Engineering, and Medicine that examined existing practices and policies on so-called dual-use biological research.

Irma is one of the most powerful Atlantic Ocean hurricanes ever recorded, and its wind speeds remain about 150 miles per hour, with stronger gusts. As this monster churns through the Caribbean and heads toward Florida, here is the lowdown.

How dangerous is it?

President Trump's pick for the next leader of NASA is a fighter pilot who wants Americans to return to the moon but doesn't believe that humans are causing climate change.

The day of the long-awaited coast-to-coast solar eclipse has arrived — and if history is any guide, it's likely that somebody's eyes are going to get hurt.
