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.

Two NASA astronauts are back on Earth after their space capsule splashed down in the Gulf of Mexico, off the coast of Pensacola, Fla.

The last time any NASA astronauts came home by splashing down was in 1975 — and back then, they were in an Apollo space vehicle. This time, the astronauts were in a white, bell-shaped capsule owned by SpaceX.

The first genetically-altered squid has scientists excited about a potential new way to study marine critters that are so weird, they've sometimes been compared to alien life forms.

A mosquito that transmits dangerous viruses like dengue and Zika seems to have developed a taste for human blood because of the way that people store water — which mosquitoes need for laying eggs — in hot, dry climates.

That's according to a new study in Current Biology that tested the biting preferences of Aedes aegypti populations from 27 locations across sub-Saharan Africa, the ancestral home of this mosquito species.

Rats will enthusiastically work to free a rat caught in a trap — and it turns out that they are especially eager to be a good Samaritan when they're in the company of other willing helpers.

But that urge to come to the rescue quickly disappears if a potential hero is surrounded by indifferent rat pals that make no move to assist the unfortunate, trapped rodent.

Almost 40 years have passed since the last time NASA astronauts blasted off into space on a brand new spaceship.

Now, as NASA looks forward to Wednesday's planned test flight of the SpaceX Crew Dragon with a pair of astronauts on board, some in the spaceflight community have a little bit of déjà vu.
