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.

Scientists have discovered how a tiny worm-like creature with no arms, legs or wings nonetheless manages to perform stupendous leaps through the air.

The acrobatic feats of these larvae were first noticed by Mike Wise of Roanoke College a few years ago, and now, in the Journal of Experimental Biology, he and some colleagues explain this critter's unusual trick.

Science has some bad news for the bearded: young children think you're really, really unattractive.

A new study suggests that, until they reach puberty, kids are strongly anti-beard — although children with bearded fathers did feel more warmly toward facial hair.

Ocean-dwelling sharks often like to hang out in areas that also get frequented by industrial fishing ships, which puts them at grave risk of being caught either for food or as bycatch.

That's according to a new study in the journal Nature that mapped the activity of 23 shark species and fishing vessels around the globe.

When a rocket carrying the first module of the International Space Station blasted off from Kazakhstan in November of 1998, NASA officials said the station would serve as an orbiting home for astronauts and cosmonauts for at least 15 years.

Mike Morrison hardly looks like a revolutionary. He's wearing a dark suit and has short hair. But we're about to enter a world of conformity that hasn't changed in decades — maybe even a century. And in there, his vision seems radical.

"We are about to walk into a room full of 100 scientific posters, where researchers are trying to display their findings on a big poster board," says Morrison, a doctoral student in psychology at Michigan State University.

At the Marine Biological Laboratory in Woods Hole, Mass., there's a room filled with burbling aquariums. A lot of them have lids weighed down with big rocks.

"Octopuses are notorious for being able to, kind of, escape out of their enclosures," says Bret Grasse, whose official title at MBL is "manager of cephalopod operations" — cephalopods being squid, cuttlefish and octopuses.

Imagine spending 40 years and more than a billion dollars on a gamble.

That's what one U.S. government science agency did. It's now paying off big time, with new discoveries about black holes and exotic neutron stars coming almost every week.

AILSA CHANG, HOST:

The asteroid is in a horrible orbit and has a 1% chance of striking Earth in just eight years. And — thank goodness — it doesn't really exist.

It's a fictitious asteroid that's the focus of a realistic exercise devised for scientists and engineers from around the world who are attending the 2019 Planetary Defense Conference being held this week outside Washington, D.C.

A real asteroid of this size, should it ever hit the planet, could wipe out an entire city.

The brains of dead pigs have been somewhat revived by scientists hours after the animals were killed in a slaughterhouse.

The Yale University research team is careful to say that none of the brains regained the kind of organized electrical activity associated with consciousness or awareness. Still, the experiment described Wednesday in the journal Nature showed that a surprising amount of cellular function was either preserved or restored.

Salt has existed for millions of years. The Salt Institute has existed for just over a century. And now it has dissolved.

Mosquitoes searching for a meal of blood use a variety of clues to track down humans, including our body heat and the carbon dioxide in our breath. Now, research shows that a certain olfactory receptor in their antennae also serves as a detector of humans, responding to smelly chemicals in our sweat.

Scientists are about to restart the two giant facilities in the United States that register gravitational waves, the ripples in the very fabric of the universe that were predicted by Albert Einstein more than a century ago.

Einstein realized that when massive objects such as black holes collide, the impact sends shock waves through space-time that are like the ripples in water created by tossing a pebble in a pond.
