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.

Decoded DNA Reveals Details Of Black Death Germ

Victims of the plague are consigned to a communal burial during the Plague of London in 1665.

Scientists have used DNA lurking inside the teeth of medieval Black Death victims to figure out the entire genetic code of the deadly bacterium that swept across Europe more than 600 years ago, killing an estimated half of the population.

The researchers didn't find any genetic feature that could explain why the plague was so virulent, according to a report just published in the journal Nature.

Asteroids Pose Less Risk To Earth Than Thought

Our planet's risk of being hit by a dangerous outer space rock may be smaller than scientists previously thought. That's according to a survey of the sky that NASA is calling the most accurate census yet of near-Earth asteroids.

A NASA space telescope called the Wide-field Infrared Survey Explorer, or WISE, recently went searching for asteroids lurking nearby — and found far fewer than astronomers had expected.

Health Officials: Listeria Outbreak Linked To 13 Deaths

A listeria outbreak linked to cantaloupes from Colorado has infected 72 people in the United States and killed 13, U.S. health officials said on Tuesday. The food-borne outbreak is the deadliest in the United States in more than a decade, according to the U.S. Centers for Disease Control and Prevention.

Where Falling Satellite Lands Is Anyone's Guess

This artist's conceptual image shows the Upper Atmosphere Research Satellite, or UARS. After two decades in orbit, the satellite will make an uncontrolled re-entry into the Earth's atmosphere.

Later this week, a retired NASA satellite the size of a school bus will finally fall back towards Earth after orbiting the planet for two decades. Most of it will burn up in the atmosphere. But about two dozen pieces are expected to hit the ground — somewhere.

And the biggest piece will weigh about 300 pounds.

If that's got you worried, NASA emphasizes that in the history of the space age, there have been no confirmed reports of falling space junk hurting anyone. But that doesn't mean no one has ever been hit.
