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.

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.
