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.

Study Reveals What Happens During A 'Glacial Earthquake'

When giant icebergs break off of huge, fast-moving glaciers, they essentially push back on those rivers of ice and temporarily reverse the flow.

That's according to a new study of "glacial earthquakes," an unusual kind of temblor discovered just over a decade ago.

How The Turtle Got Its Shell

The fossilized remains of a bizarre-looking reptile are giving scientists new insights into how turtles got their distinctive shells.

Some 240 million years ago, this early turtle-like creature lived in a large lake, in a fairly warm, subtropical climate. But it didn't have the kind of shell modern turtles have, says Hans-Dieter Sues, a curator at the Smithsonian's National Museum of Natural History in Washington, D.C.

Instead Of Replacing Missing Body Parts, Moon Jellies Recycle

Upon injury, juvenile jellyfish reorganize their bodies to regain symmetry.

Moon jellies have an unusual self-repair strategy, scientists have learned. If one of these young jellies loses some limbs, it simply rearranges what's left until its body is once again symmetrical.

"We were not expecting to see that," says Michael Abrams, a graduate student in biology at the California Institute of Technology.

All creatures have tricks to heal themselves. If you get a cut, your skin will form a scar. And some sea creatures, like starfish and sea cucumbers, can regenerate lost body parts.

Saturn's Dark And Mysterious Outer Ring Is Even Bigger Than Expected

Saturn is famous for its lovely rings, but this gas giant has another ring that people normally don't see — and some new observations with an infrared telescope show that this mysterious ring is even bigger than scientists thought.

The first hint that Saturn had this secret ring came back in 1671, when the Italian astronomer Giovanni Domenico Cassini looked through a telescope and discovered the moon now known as Iapetus.

How Many Viruses Have Infected You?

Originally published on Fri June 5, 2015 3:12 pm

A cheap new lab test can use just a drop of blood to reveal the different kinds of viruses you've been exposed to over your lifetime.

The test suggests that, on average, people have been infected with about ten different types of known virus families, including influenzas, and rhinoviruses that cause the common cold, according to a report published Thursday in Science.
