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.

Giant flares and eruptions from the Sun can cause space weather--and stormy space weather can interfere with everything from satellites to the electrical grid to airplane communications. Now, though, there's good news for people who monitor the phenomenon--the Sun has passed from one of its 11-year activity cycles into another, and scientists predict that the new cycle should be just about as calm as the last.

Scientists say they've detected a gas in the clouds of Venus that, on Earth, is produced by microbial life.

The researchers have racked their brains trying to understand why this toxic gas, phosphine, is there in such quantities, but they can't think of any geologic or chemical explanation.

The mystery raises the astonishing possibility that Venus, the planet that comes closest to Earth as it whizzes around the sun, might have some kind of life flourishing more than 30 miles up in its yellow, hazy clouds.

Mike Brown has been using the Hubble Space Telescope pretty consistently for most of the past three decades since it launched in 1990. But recently he had an experience with Hubble that he never had before.

With the annual flu season about to start, it's still unclear exactly how influenza virus will interact with the coronavirus if a person has both viruses.

Water is everywhere on Earth - the clouds, the rain, the oceans and rivers, even our own bodies. Where all that water originally came from is a bit of a mystery. NPR's Nell Greenfieldboyce reports that scientists may have found the answer inside some rare meteorites.
