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.

The Latest Word From WHO On Experimental Ebola Therapies

Originally published on Fri September 5, 2014 2:21 pm

Proteins and enzymes that will produce antibodies for the experimental Ebola drug ZMapp are developed on the leaves of the nicotiana benthamiana plant, a relative of tobacco. Here, indicator proteins glow under ultraviolet light — a way to assess the success of bacteria spread.

One of the reasons Ebola is so terrifying is that there's no vaccine and no cure. But the World Health Organization hopes to change that, with plans to quickly test experimental products during this outbreak.

By November, two promising vaccines will have been tested on people to see if they're safe, says Marie-Paule Kieny, assistant director-general at WHO.

How Much Bigger Is The Ebola Outbreak Than Official Reports Show?

Originally published on Thu August 21, 2014 2:05 pm

Workers with the aid group Doctors Without Borders prepare a new Ebola treatment center near Monrovia, Liberia, on Sunday. The facility has 120 beds, making it the largest Ebola isolation clinic in history.

The latest numbers on the Ebola outbreak are grim: 2,473 people infected and 1,350 deaths.

That's the World Health Organization's official tally of confirmed, probable and suspect cases across Guinea, Liberia, Sierra Leone and Nigeria. But the WHO has previously warned that its official figures may "vastly underestimate the magnitude of the outbreak."

So how bad is it really?

A Virtual Outbreak Offers Hints Of Ebola's Future

While the Ebola outbreak continues to rage in West Africa, it is also unfolding — in a virtual sense — inside the computers of researchers who study the dynamics of epidemics.

Policymakers look to these simulations to get a sense of how the outbreak might spread. They also can use them to run experiments to see which public health measures should take priority.

The World Health Organization Says Yes To An Experimental Ebola Drug

A panel of experts convened by the World Health Organization has unanimously endorsed the idea of offering unproven vaccines or treatments to help combat the unprecedented Ebola outbreak in West Africa.

This outbreak is unusual not just because it has spread to four countries and involves so many people, says Dr. Marie-Paule Kieny, Assistant Director-General at the World Health Organization. It is also the first Ebola outbreak that could possibly benefit from a range of potential experimental treatments and vaccines.

Big Data Peeps At Your Medical Records To Find Drug Problems

Originally published on Tue July 22, 2014 1:43 pm

Katherine Streeter for NPR

No one likes it when a new drug in people's medicine cabinets turns out to have problems — just remember the Vioxx debacle a decade ago, when the painkiller was removed from the market over concerns that it increased the risk of heart attack and stroke.

To do a better job of spotting unforeseen risks and side effects, the Food and Drug Administration is trying something new — and there's a decent chance that it involves your medical records.

The Little Spacecraft That Couldn't

Originally published on Thu July 10, 2014 2:03 pm

Early days: NASA's International Sun-Earth Explorer C (also known as ISEE-3 and ICE) was undergoing testing and evaluation inside the Goddard Space Flight Center's dynamic test chamber when this photo was snapped in 1976.

An audacious quest to reconnect with a vintage NASA spacecraft has suffered a serious setback and is now pretty much over.

The satellite launched in 1978 and has been in a long, looping orbit around the sun for about three decades. Earlier this year, NPR told you about an effort to get in touch with this venerable piece of NASA hardware and send it on one more adventure.

But there are no guarantees when you try to recapture the past.

A Shocking Fish Tale Surprises Evolutionary Biologists

Originally published on Sat July 12, 2014 11:39 am

A 6-foot-long electric eel is basically a 6-inch fish attached to a 5-1/2-foot cattle prod, researchers say. The long tail is packed with special cells that pump electricity without shocking the fish.

The electric eel's powerful ability to deliver deadly shocks — up to 600 volts — makes it the most famous electric fish, but hundreds of other species produce weaker electric fields. Now, a new genetic study of electric fish has revealed the surprising way they got electrified.

How To Become A Neanderthal: Chew Before Thinking

Originally published on Fri June 20, 2014 9:54 am

By comparing "Skull 17" from the Sima de los Huesos site with many others found in the same cave, researchers were able to discern the common facial features of the era.
Javier Trueba Madrid Scientific Films

Scientists have long puzzled over the origin and evolution of our closest relative, the Neanderthal. Now, researchers say Neanderthals seem to have developed their distinctive jaws and other facial features first, before they evolved to have big brains.

That's according to an analysis of 17 skulls, all taken from one excavation site in a mountain cave in Atapuerca, Spain, known as the Sima de los Huesos — the "pit of bones."

Is Collecting Animals For Science A Noble Mission Or A Threat?

Originally published on Wed June 18, 2014 7:29 am

DNA from these crab plovers, collected in Djibouti, Africa, should help scientists figure out how the unusual species fits into the family tree, says the Smithsonian's Helen James.
Maggie Starbard NPR

Behind the scenes at the Smithsonian's National Museum of Natural History, there's a vast, warehouse-like room that's filled with metal cabinets painted a drab institutional green. Inside the cabinets are more than a half-million birds — and these birds are not drab. Their colorful feathers make them seem to almost glow.

Big Flightless Birds Come From High-Flying Ancestors

Originally published on Thu May 22, 2014 7:06 pm

The egg definitely came before the chicken in this case — the skeleton is from a modern adult kiwi, the egg from its much bigger, long-extinct cousin, Aepyornis maximus.
Kyle Davis and Paul Scofield Canterbury Museum

Big, flightless birds like the ostrich, the emu and the rhea are scattered around the Southern Hemisphere because their ancestors once flew around the world, a new study suggests.

That's a surprise, because it means birds in Australia, Africa and South America independently evolved in ways that made them all lose the ability to fly.

Why This Octopus Isn't Stuck-Up

Originally published on Thu May 15, 2014 7:18 pm

Octopus arms keep from getting all tangled up in part because some kind of chemical in octopus skin prevents the tentacles' suckers from grabbing on.

That was the surprise discovery of scientists who were trying to understand how octopuses manage to move all their weird appendages without getting tied in knots.

Unlike humans, octopuses don't have a constant awareness of their arms' locations. It's kind of like the eight arms have minds of their own. And as an octopus arm travels through the water, its neighboring arms are constantly in reach.

'Past The Point Of No Return:' An Antarctic Ice Sheet's Slow Collapse

Originally published on Tue May 13, 2014 9:04 am

Transcript

MELISSA BLOCK, HOST:

Antarctica is covered with the biggest mass of ice on earth. The part of the ice sheath that's over West Antarctica is thought to be especially vulnerable to climate change. Scientists now say a slow collapse of the West Antarctic ice sheet is both underway and irreversible. And as NPR's Nell Greenfieldboyce reports, this could eventually raise sea levels more than 10 feet.

NELL GREENFIELDBOYCE, BYLINE: For decades, scientists have worried about the West Antarctic ice sheet.
