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.

Should the Irish Giant be allowed to rest in peace?

That's the question swirling around the bones of Charles Byrne, a literal giant from Ireland who was an 18th century celebrity.

Scientists around the United States are getting ready to do an unprecedented experiment: They plan to march en masse in Washington, D.C., and other cities on April 22, to take a stand for the importance of public policies based on science.

Some researchers predict that this March for Science will release much needed energy and enthusiasm at a time when science is under threat; others worry it will damage science's reputation as an unbiased seeker of truth.

A small, faint star relatively close by is home to seven Earth-size planets with conditions that could be right for liquid water and maybe even life.

The discovery sets a record for both the most Earth-size planets and the most potentially habitable planets ever discovered around a single star.

The space capsule that took the first moonwalkers on their historic adventure is getting ready to take off on another trip — its first tour of the United States in more than 40 years.

Plants that feed on flesh have fascinated scientists going all the way back to Charles Darwin, and researchers now have new insight into how these meat-eaters evolved.

Even plants that evolved continents away from one another rely on strikingly similar tricks to digest their prey.

Last year, global warming reached record high temperatures — and if that news feels like déjà vu, you're not going crazy.

The planet has now had three consecutive years of record-breaking heat.

Tying a knot can be tricky. Just ask any kid struggling with shoelaces. And scientists have it even harder when they try to make knots using tiny molecules.

Now, in the journal Science, a team of chemists says it has made a huge advance — manipulating molecules to create the tightest knot ever.

Menopause is a mystery to evolutionary biologists, but new insights could come from a long-term study of killer whales.

In these whales, the explanation may lie in a combination of conflict and cooperation between older and younger females, according to a report published Thursday in the journal Current Biology.

Terrorist attacks, hurricanes, a divisive U.S. election, Brexit — 2016 has not been easy. With the year coming to an end, we thought it was time to get some serious perspective — from the scale of the entire universe.

We're tackling big questions: what scientists know, and what they have yet to learn.

So before you ring in another year, take a moment to contemplate the billions of years that led to 2017 and the billions more yet to come.

The holiday season is a time when lots of people take to the air, flying to see relatives or go on vacation. But when it comes to seasonal travel, humans are totally outnumbered by insects.

That's according to a newly published study in the journal Science, which found that more than 3 trillion migrating insects fly over south-central England each year.

In a technological tour de force, scientists have developed a new way to probe antimatter.

For the first time, researchers were able to zap antimatter atoms with a laser, then precisely measure the light let off by these strange anti-atoms. By comparing the light from anti-atoms with the light from regular atoms, they hope to answer one of the big mysteries of our universe: Why, in the early universe, did antimatter lose out to regular old matter?

If you could change the way a monkey or an ape's brain is wired, that animal would be capable of producing perfectly intelligible speech.

That's the conclusion of a study that closely tracked the movements of a monkey's mouth and throat with X-rays, to understand the full potential of its vocal tract.

The surprise find of smallpox DNA in a child mummy from the 17th century could help scientists start to trace the mysterious history of this notorious virus.

Smallpox currently only exists in secure freezers, after a global vaccination campaign eradicated the virus in the late 1970s. But much about this killer remains unknown, including its origins.

President-elect Donald Trump intends to nominate Oklahoma Attorney General Scott Pruitt to head the Environmental Protection Agency, announcing his decision in a statement Thursday.

As attorney general, Pruitt has made no secret of his disdain for the EPA.

Around the corner from the famous Diamond District in New York City, David Weinstein sorts through some envelopes on his cluttered desk. All of them are full of diamonds.

"I deal with diamonds all day long, for three decades," says Weinstein, executive director of the International Gemological Institute, a commercial testing laboratory. "To me, diamonds aren't anything spectacular. It's hard to get me to say, 'Wow!' "

ARI SHAPIRO, HOST:

The good news for those worried that the U.S. will lose its leadership role in confronting climate change: President-elect Donald Trump said Tuesday, "I have an open mind to it. ... I do have an open mind."

At a meeting Tuesday with New York Times journalists and executives, Trump said he thinks "there is some connectivity" in terms of human activity causing climate change.

A rusty-brown rock found on a beach by a fossil hunter might contain a bit of preserved dinosaur brain.

If so, it would be the first time scientists have ever found fossilized brain tissue from a dinosaur.

The fossil comes from a species closely related to Iguanodon, a large herbivore that lived about 130 million years ago. A collector named Jamie Hiscocks found it in 2004, near Bexhill in the United Kingdom.

When scientists recently announced that they had discovered a new planet orbiting our closest stellar neighbor, Proxima Centuri, they also released an artist's conception of the planet.

On Election Day this November, about 1 in 4 Americans will vote using a device that never lets the voter see a copy of his or her vote on paper.
