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.

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.

The nation's foremost public health agency shies away from discussing the important link in this country between suicide and access to guns.

That's according to documents obtained by NPR that suggest the Centers for Disease Control and Prevention instead relies on vague language and messages about suicide that effectively downplay and obscure the risk posed by firearms.

Guns in the United States kill more people through suicide than homicide.

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.

A drone called Dragonfly will be buzzing around Saturn's largest moon in 2034, if all goes according to plan.

That's because NASA has picked a mission to the icy moon Titan for its next major foray out into the solar system.

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.

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.

Scientists have taken the first photo of something invisible - a black hole. For decades, black holes have captured people's imaginations.

On April 1, scientists will officially restart their search for gravitational waves after a year spent making improvements to massive twin detectors. Discoveries should soon start rolling in, and when they do, there's a good chance the news will be translated into a Native American language called Blackfoot, or Siksika.

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.

On a launch pad in Florida, SpaceX is getting ready for the first flight test of its new space capsule designed to carry astronauts.

Even though the Crew Dragon capsule won't have any people on board when SpaceX's Falcon 9 rocket blasts off Saturday morning, assuming the schedule doesn't slip, it's still a huge deal for U.S. spaceflight.

Historic preservationists are hoping that the upcoming 50th anniversary of the Apollo 11 moon landing this summer will persuade the United Nations to do something to protect Neil Armstrong's footprints in the lunar dust.

When Martin Luther King, Jr. was in high school, he won an oratorical contest sponsored by the Negro Elks. He and a beloved teacher were returning home in triumph, riding on a bus, when some white passengers got on. The white bus driver ordered King and his teacher to give up their seats, and cursed them. King wanted to stay seated, but his teacher urged him to obey the law. They had to stand in the aisle for the 90 miles back to Atlanta, Ga.

Hungry deer in the northeastern U. S. are likely changing the acoustics of their forests by eating up bushes, small trees and other leafy plants that normally would affect the transmission of natural sounds such as bird calls.

Registered nurse Ebony Monroe of Houston recently went through a period of being quick to anger about every little thing. She didn't realize then what it might mean for her health.

"If you had told me in the beginning that my irritability was related to depression, I would probably be livid," Monroe says with a laugh. "I did not think irritability aligned with depression."

Saturn is famous for its lovely rings, but a new study suggests the planet has spent most of its 4.5 billion years without them.

That's because the rings are likely only 10 million to 100 million years old, according to a newly published report in the journal Science that's based on findings from NASA's Cassini probe.

Tiny bits of blue pigment found in the teeth of a medieval skeleton reveal that more than 850 years ago, this seemingly ordinary woman was very likely involved in the production of lavishly illustrated sacred texts.

China has landed a spacecraft on the side of the moon that's never seen from Earth. And NPR's Nell Greenfieldboyce reports it's part of a methodical plan that China has laid out for space exploration.

New images of a mysterious world at the far reaches of our solar system show that it's shaped much like a snowman, with one large icy sphere attached to a smaller one.

The shape indicates that a rotating cloud of innumerable tiny objects must have coalesced into two balls that slowly spiraled closer and closer together until they gently touched, forming the object out beyond Pluto that scientists have nicknamed "Ultima Thule," which means "beyond the known world."
