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.

A panel of experts that advises the Centers for Disease Control and Prevention has given its blessing to a new one-shot vaccine for COVID-19.

Tattoo artists in Europe are fighting a new ban on two commonly-used green and blue pigments, saying that losing these ink ingredients would be a disaster for their industry and their art.

A NASA spacecraft successfully touched down on a skyscraper-sized asteroid 200 million miles away, in order to collect a small amount of rock and dust that can then be returned to Earth.

The probe, called OSIRIS-REx, is about as big as a 15-passenger van, and it was aiming for a specific spot inside a boulder-strewn crater. The maneuver was tricky and fraught with peril, as the spacecraft had to reach a safe area that's only the size of a few parking spaces.

Last week, craving sweets, Colin Purrington remembered the Twinkies.

He'd purchased them back in 2012 for sentimental reasons when he heard that Hostess Brands was going bankrupt and Twinkies might disappear forever.

"When there's no desserts in the house, you get desperate," says Purrington, who went down to the basement and retrieved the old box of snack cakes, fully intending to enjoy several.

The Nobel Prize in chemistry was awarded this year to Emmanuelle Charpentier and Jennifer Doudna for their work on "genetic scissors" that can cut DNA at a precise location, allowing scientists to make specific changes to specific genes.

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.

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 on Earth is omnipresent and essential for life as we know it, and yet scientists remain a bit baffled about where all of this water came from: Was it present when the planet formed, or did the planet form dry and only later get its water from impacts with water-rich objects such as comets?

This year's flu season in the Southern Hemisphere was weirdly mild.

A surprisingly small number of people in the Southern Hemisphere have gotten the flu this year, probably because the public health measures put in place to fight COVID-19 have also limited the spread of influenza.

That makes public health experts hopeful that the U. S. and other northern countries might be spared the double whammy of COVID-19 and a bad flu season this winter.

Still, they warn against complacency and say people still need to get vaccinated against the flu.

When a weather station in Death Valley, Calif., registered an astonishing 130 degrees Fahrenheit this week, it got meteorologists' attention.

After all, there's a possibility that this is the highest such temperature ever reliably recorded on Earth — if it's for real.
