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.

New York City is set to begin giving body cameras to its police officers on Thursday.

Under the police department's pilot program, 1,200 officers in 20 precincts will receive the cameras. The officers will also be studied by scientists to see what effect the cameras have on policing.

As police don body cameras across the country, scientists are increasingly working with departments to figure out how the cameras change behavior — of officers and the public.

Baby humpback whales seem to whisper to their mothers, according to scientists who have captured the infant whales' quiet grunts and squeaks.

The recordings, described in the journal Functional Ecology, are the first ever made with devices attached directly to the calves.

Leave no man behind. That's an old idea in warfare — it's even part of the Soldier's Creed that Army recruits learn in basic training.

And never leaving a fallen comrade is also the rule for some warriors who are ants, according to a report published Wednesday in the journal Science Advances.

President Trump issued a sweeping executive order on Tuesday that will begin to undo a slew of government efforts to fight global warming.

Among those worrying and watching to see how the executive order plays out are scientists who actually are in favor of exploring bold interventions to artificially cool the climate.

Safety advocates are worried that lawmakers are getting ready to make it harder to penalize companies that don't keep track of workers' injuries.

Since 1971, the Occupational Safety and Health Administration has required many employers to keep careful records of any worker injuries or illnesses.

If there was any doubt over President Trump's views on climate change, those doubts evaporated with the unveiling of his proposed federal budget on Thursday.

The budget would end programs to lower domestic greenhouse gas emissions, slash diplomatic efforts to slow climate change and cut scientific missions to study the climate.

ARI SHAPIRO, HOST:

Scientists around the United States are getting ready to do an unprecedented experiment: They plan to march en masse in Washington, D.C., and other cities on April 22, to take a stand for the importance of public policies based on science.

Some researchers predict that this March for Science will release much needed energy and enthusiasm at a time when science is under threat; others worry it will damage science's reputation as an unbiased seeker of truth.

A small, faint star relatively close by is home to seven Earth-size planets with conditions that could be right for liquid water and maybe even life.

The discovery sets a record for both the most Earth-size planets and the most potentially habitable planets ever discovered around a single star.

The space capsule that took the first moonwalkers on their historic adventure is getting ready to take off on another trip — its first tour of the United States in more than 40 years.
