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.

If signs of life are found on a planet beyond our solar system sometime in the next decade, they'll most likely be on a planet discovered by a NASA satellite that's scheduled to launch on Monday.

The supermassive black hole lurking at the center of our galaxy appears to have a lot of company, according to a new study that suggests the monster is surrounded by about 10,000 other black holes.

For decades, scientists have thought that black holes should sink to the center of galaxies and accumulate there, says Chuck Hailey, an astrophysicist at Columbia University. But scientists had no proof that these exotic objects had actually gathered together in the center of the Milky Way.

Government health agencies have spent more than two decades shying away from gun violence research, but some say the new spending bill, signed by President Trump on Friday, will change that.

That is because, in agency instructions that accompany the bill, there is a sentence noting that the Centers for Disease Control and Prevention has the authority to conduct research on the causes of gun violence.

A Chinese space lab the size of a city bus will soon be falling back to Earth, and no one knows exactly where bits of it might crash down.

Genetic mutations are the driving force of evolution, and now scientists have managed to study the effect of mutations in exquisite detail by watching what happens as they pop up in single cells.

Only about one percent of mutations were bad enough to kill off the cell, according to a report published Thursday in Science. Most of the time, these small changes in its DNA appeared to have no effect at all.

Everyone from NASA to the cast of The Big Bang Theory is reacting Wednesday to the death of acclaimed physicist Stephen Hawking, known for his work on understanding the nature of black holes.

In the brave new world of synthetic biology, scientists can now brew up viruses from scratch using the tools of DNA technology.

The latest such feat, published last month, involves horsepox, a cousin of the feared virus that causes smallpox in people. Critics charge that making horsepox in the lab has endangered the public by basically revealing the recipe for how any lab could manufacture smallpox to use as a bioweapon.

A rocket more powerful than any other flying today is scheduled to blast off Tuesday for the first time, if all goes well.

Even very young babies can tell the difference between someone who's helpful and someone who's mean — and lab studies show that babies consistently prefer the helpers.

But one of humans' closest relatives — the bonobo — makes a different choice, preferring to cozy up to the meanies.

That's according to experiments described Thursday in the journal Current Biology, by scientists who wanted to explore the evolutionary origins of humans' unusually cooperative behavior.

This is Lauren's log, stardate December 31, 2017. Captain Lulu Garcia-Navarro is away, but we continue the mission to explore matters of space, the stars and the universe.

The end of the year is a time of holiday gift giving, and finding just the right gift can sometimes feel like an impossible task. But folks at an animal eyeball lab say that a gift they've just received, partly thanks to NPR, has made this the "best Christmas ever."

It's a massive whale eye, probably from a blue whale, and the story of how it ended up at the lab starts in the 1960s.

Scientists could soon resume controversial experiments on germs with the potential to cause pandemics, as government officials have decided to finally lift an unusual three-year moratorium on federal funding for the work.

The research involves three viruses — influenza, SARS, and MERS — that could kill millions if they mutated in a way that let the germs spread quickly among people.
