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.

At least one young woman suffered eye damage as a result of unsafe viewing of the recent total solar eclipse, according to a report published Thursday, but it doesn't appear that many such injuries occurred.

Doctors in New York say a woman in her 20s came in three days after looking at the Aug. 21 eclipse without protective glasses. She had peeked several times, for about six seconds, when the sun was only partially covered by the moon.

Scientists have just discovered a supermassive black hole that existed surprisingly early in the history of the universe, and the puzzling find is shedding new light on when the first stars blinked on.

Astronomers spotted the black hole, the most distant ever found, sitting inside a bright object so far away that the light had been traveling for 13 billion years before reaching Earth.

The ever-widening use of artificial lights is making the nighttime Earth glow increasingly brighter, with the amount of global light growing about 2 percent each year.

That worries advocates for the protection of dark skies, who say that artificial night glow can affect wildlife like migrating birds and keeps people from connecting to the stars. What's more, they say, all that wasted light sent out into space is effectively wasted money.

Scientists believe they may have new insights into why passenger pigeons went extinct, after analyzing DNA from the toes of birds that have been carefully preserved in museums for over a century.

The Great Pyramid of Giza has been probed with the tools of modern particle physics by scientists who say they have discovered a huge, secret space hidden within its ancient walls.

It is located above a tall, cathedral-like room known as the Grand Gallery, and this newly found space is comparable in size — about 100 feet long, according to a report in the journal Nature.

Astronomers have spotted some kind of outer space rock that's the first visitor from outside of our solar system that they've ever observed.

The discovery has set off a mad scramble to point telescopes at this fast-moving object to try to learn as much as possible before it zips out of sight.

Having police officers wear little cameras seems to have no discernible impact on citizen complaints or officers' use of force, at least in the nation's capital.

That's the conclusion of a study performed as Washington, D.C., rolled out its huge camera program. The city has one of the largest forces in the country, with some 2,600 officers now wearing cameras on their collars or shirts.

For the first time, scientists have caught two neutron stars in the act of colliding, revealing that these strange smashups are the source of heavy elements such as gold and platinum.

Today, three scientists won the Nobel Prize in Chemistry for developing a new way to image biological molecules. NPR's Nell Greenfieldboyce has more on the winners.

Irma is one of the most powerful Atlantic Ocean hurricanes ever recorded, and its wind speeds remain about 150 miles per hour, with stronger gusts. As this monster churns through the Caribbean and heads toward Florida, here is the lowdown.

How dangerous is it?

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.
