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.

Shortly after NASA astronauts blasted off from U.S. soil for the first time since 2011, President Trump painted a dire picture of what the space agency had looked like when he first came to office.

"There was grass growing through the cracks of your concrete runways — not a pretty sight, not a pretty sight at all," he said at NASA's enormous Vehicle Assembly Building at Kennedy Space Center in Florida, where he had come to watch two astronauts launch to orbit in a vehicle owned and operated by SpaceX.

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.

In 2006, while hiking around the Root Glacier in Alaska to set up scientific instruments, researcher Tim Bartholomaus encountered something unexpected.

"What the heck is this!" Bartholomaus recalls thinking. He's a glaciologist at the University of Idaho.

The White House has touted the fact that its coronavirus task force provided each state with a list of labs that could potentially test for the virus, but officials in a number of states told NPR that the lists did not actually help them increase testing.

Because of the coronavirus, NASA's top official is asking space fans not to travel to Florida later this month to watch astronauts blast off from American soil for the first time since the retirement of the space shuttles in 2011.

As the coronavirus sweeps across the globe, one pattern remains consistent: Men seem harder hit by the virus than women and are more likely to have severe illness or die.

At least in the United States, however, it seems that men are less likely to seek out testing for the virus when they feel sick.

Tiny bits of twisted plant fibers found on an ancient stone tool suggest that Neanderthals were able to make and use sophisticated cords like string and rope.

Cords made from twisted fibers are so ubiquitous today that it's easy to take them for granted. But they're a key survival technology that can be used to make everything from clothes to bags to shelters.

The Trump administration has issued new guidelines in a small first step towards reopening the country. These guidelines should make it easier for essential workers to stay on the job. NPR science correspondent Nell Greenfieldboyce is here. Hi, Nell.

When researcher Josh Santarpia stands at the foot of a bed, taking measurements with a device that can detect tiny, invisible particles of mucus or saliva that come out of someone's mouth and move through the air, he can tell whether the bedridden person is speaking or not just by looking at the read-out on his instrument.

The World Health Organization says the virus that causes COVID-19 doesn't seem to linger in the air or be capable of spreading through the air over distances of more than about 3 feet.

But at least one expert in virus transmission said it's way too soon to know that.

The latest figures on coronavirus tests run so far in the U.S. were put at about 552,000, according to government officials during the Thursday's briefing of the White House Coronavirus Task Force.

"The testing is going very, very well," President Trump said.

At a time when the nation is desperate for authoritative information about the coronavirus pandemic, the country's foremost agency for fighting infectious disease outbreaks has gone conspicuously silent.

"I want to assure Americans that we have a team of public health experts," President Trump said at Tuesday evening's coronavirus task force briefing — a bit of reassurance that probably would not have been necessary if that briefing had included anyone from the Centers for Disease Control and Prevention.
