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.

DNA Blood Test Gives Women A New Option For Prenatal Screening

Ultrasound is often used for prenatal screening. It's just one of several prenatal screenings available to pregnant women.

When Amy Seitz got pregnant with her second child last year, she knew that being 35 years old meant there was an increased chance of chromosomal disorders like Down syndrome. She wanted to be screened, and she knew just what kind of screening she wanted — a test that's so new, some women and doctors don't quite realize what they've signed up for.

Maybe Early Humans Weren't The First To Get A Good Grip

An example of a human precision grip — grasping a first metacarpal from the thumb of a specimen of Australopithecus africanus that's thought to be 2 to 3 million years old.

The special tool-wielding power of human hands may go back farther in evolutionary history than scientists have thought.

That's according to a new study of hand bones from an early relative of humans called Australopithecus africanus. Researchers used a powerful X-ray technique to scan the interior of the bones, and they detected a telltale structure that's associated with a forceful precision grip.

The bar-headed goose is famous for its long, annual migration from the Indian subcontinent to central Asia, a flight that takes it over snowcapped Himalaya Mountains so high and dangerous that human climbers struggle just to stay alive.

How A Position Of Power Can Change Your Voice

How would you sound in front of an NPR microphone?
Meredith Rizzo NPR

Originally published on Mon February 9, 2015 5:37 pm

Most radio reporters, I think it's fair to say, think about their voices a lot, and work to sound powerful and authoritative. I know my voice has changed since my very first radio story 10 years ago:

Compare that with how I sound these days:

These Froggies Went A Courtin' And Gave Birth To Live Tadpoles

The newly described L. larvaepartus (male, left, and female) from Indonesia's island of Sulawesi. Odd, sure, but at least they don't use their stomachs as breeding chambers, as some other frogs do.

When Jim McGuire and some colleagues recently cut open a frog that they'd collected and euthanized on an Indonesian island, they got quite a shock.

"Out came the tadpoles, and they were alive!" recalls McGuire, a herpetologist at the University of California, Berkeley.

The researchers had just found the first frog known to give birth to live tadpoles.

When Humans Quit Hunting And Gathering, Their Bones Got Wimpy

Farming helped fuel the rise of civilizations, but it may also have given us less robust bones.

Compared with other primates and our early human ancestors, we modern humans have skeletons that are relatively lightweight — and scientists say that basically may be because we got lazy.

Worries About Unusual Botulinum Toxin Prove Unfounded

Originally published on Fri December 19, 2014 3:12 pm

Remember that worrisome new form of botulinum toxin we told you about in late 2013, the one that supposedly had to be kept secret out of fear it could be used as a bioweapon that would evade all of our medical defenses?

Well, as it turns out, it's not that scary after all. The antitoxin stored in the government's emergency stockpile works and would neutralize the toxin just fine.

Imagine that scientists wanted to take Ebola virus and see if it could ever become airborne by deliberately causing mutations in the lab and then searching through those new viruses to see if any spread easily through the air.

Would that be OK?

Earliest Human Engraving Or Trash From An Ancient Lunch?

An inside view of this fossil Pseudodon shell shows that the hole made by Homo erectus is exactly at the spot where the muscle attached to the shell. Poking at that spot would force the shell open.
Henk Caspers Naturalis Leiden/The Netherlands

Scientists have discovered enigmatic markings on an ancient shell that's been sitting in a museum for more than a century — and they believe this may be the oldest known example of a deliberate geometric engraving made by a human hand.

These X's Are The Same Shade, So What Does That Say About Color?

This is a re-creation of a color plate from Interaction of Color, by Josef Albers. The two X's are are exactly the same — it's the different backgrounds that make them look like very different colors.

Learning to name the colors is a ritual of childhood. At first kids have no clue; often they'll just say everything is "boo." Pretty soon, though, they can rattle off Roy G. Biv with aplomb. Still, that doesn't mean they understand what color actually is.

Mark Fairchild, who studies color and vision science at the Rochester Institute of Technology, says that even physicists get it wrong when they confidently assert that color is just a wavelength of light.
