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.

For years, the government has been trying to reduce the risk that legitimate biological research could be misused to threaten the public's health, but those efforts have serious shortcomings.

That's the conclusion of a report released Thursday by the prestigious National Academies of Sciences, Engineering, and Medicine that examined existing practices and policies on so-called dual-use biological research.

President Trump's pick for the next leader of NASA is a fighter pilot who wants Americans to return to the moon but doesn't believe that humans are causing climate change.

The day of the long-awaited coast-to-coast solar eclipse has arrived — and if history is any guide, it's likely that somebody's eyes are going to get hurt.

Anyone who gets to see the total solar eclipse on August 21 will be lucky — and humanity is lucky to live on a planet that even has this kind of celestial event.

Mercury and Venus, after all, don't even have moons. Mars has a couple, but they're too small to completely blot out the sun. Gas giants like Jupiter do have big moons, but they don't have solid surfaces where you could stand and enjoy an eclipse.

And, even with solid land and a moon, Earth only gets its gorgeous total solar eclipses because of a cosmic coincidence.

To see this month's total solar eclipse, the first one to be visible from the contiguous United States in nearly 40 years, all Donald Liebenberg will have to do is open his front door and step outside.

"It's a really special treat to be able to have one in my driveway," says Liebenberg, who has trekked to Turkey, Zambia, China and Pukapuka, a remote island in the Pacific, to see past eclipses.

You might think that, after thousands of years of observing total solar eclipses, science-minded folks would have exhausted what can be learned from this awesome natural spectacle.

You would be wrong.

When Ralph Chou was about 12 years old, he took all the right precautions to watch his first solar eclipse.

"I did other stupid things, but when it came to looking at that eclipse, I was being very careful," says Chou, a professor emeritus of optometry and vision science at the University of Waterloo, who's a leading authority on eye damage from eclipse viewing.

Groups that represent industries from farming to fracking are supporting a legislative push to rewrite how government handles science when drawing up regulations.

And the whole effort has scientists worried.

Consider, for example, the Honest and Open New EPA Science Treatment Act, or HONEST Act, which passed the House in the spring and now is with the Senate. Just how "honest" it is depends on whom you ask.

There is a little room at the University of Wisconsin-Madison that is filled with the eyeballs of animals — everything from the duck-billed platypus to the two-toed sloth to the boa constrictor.

The Apollo 11 command module, which took the first moonwalkers to lunar orbit and back in 1969, is undergoing a painstaking restoration, in preparation for an unusual national tour later this year.

A study published Thursday shows how a bird flu virus that's sickening and killing people in China could mutate to potentially become more contagious.

Just three changes could be enough to do the trick, scientists report in the journal PLOS Pathogens.

And the news comes just as federal officials are getting ready to lift a moratorium on controversial lab experiments that would deliberately create flu viruses with mutations like these.

Scientists have found a shockingly hot, massive, Jupiter-like planet that has a tail like a comet.

"It is so hot that it is hotter than most stars that we know of out there," says Scott Gaudi of Ohio State University in Columbus, Ohio, whose team describes the scorching world called KELT-9b in the journal Nature.

Common blood tests for lead can give falsely-low results in certain cases, according to a new warning from the Food and Drug Administration.

The tests, manufactured by Magellan Diagnostics, are commonly used in doctors' offices and clinics, and on its website the company calls itself "the most trusted name in lead testing." But the FDA now says that its tests can give inaccurate results when used to test blood drawn from a vein.

The teeth of Tyrannosaurus rex have been called "killer bananas," and a new study in the journal Scientific Reports shows just how hard those fearsome chompers could clamp down.

"What we came up with were bite forces of around 8,000 pounds," says Gregory Erickson of Florida State University. "That's like setting three small cars on top of the jaws of a T. rex — that's basically what was pushing down."

New York City is set to begin giving body cameras to its police officers on Thursday.

Under the police department's pilot program, 1,200 officers in 20 precincts will receive the cameras. The officers will also be studied by scientists to see what effect the cameras have on policing.

As police don body cameras across the country, scientists are increasingly working with departments to figure out how the cameras change behavior — of officers and the public.
