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 Dwarf Planet Found At The Solar System's Outer Limits

Originally published on Thu March 27, 2014 6:44 am

This diagram for the outer solar system shows the orbits of Sedna (in orange) and 2012 VP113 (in red). The sun and terrestrial planets are at the center, surrounded by the orbits (in purple) of the four giant planets — Jupiter, Saturn, Uranus and Neptune. The Kuiper belt, which includes Pluto, is shown by the dotted light blue region.

Scientists have spotted a new dwarf planet at the edge of our solar system. It's a kind of pink ice ball that's way out there, far beyond Pluto.

Astronomers used to think this region of space was a no man's land. But the new findings suggest that it holds many small worlds — and there are even hints of an unseen planet bigger than Earth.

Space Thief Or Hero? One Man's Quest To Reawaken An Old Friend

More than 30 years ago, Robert Farquhar stole a spacecraft.

Now he's trying to give it back.

The green satellite, covered with solar panels, is hurtling back toward the general vicinity of Earth, after nearly three decades of traveling in a large, looping orbit around the sun.

Scientists have used a powerful new technique to prove that some tiny crystals found in Western Australia are indeed the oldest known materials formed on Earth.

Back in 2001, scientists reported that one of the zircon crystals was about 4.4 billion years old — so old that not everyone believed it.

"There have been challenges, because nothing in science goes without being questioned. It always has to be proven," says John Valley, a geochemist at the University of Wisconsin, Madison.

Termites can build huge, elaborate mounds that rise up from the ground like insect skyscrapers; scientists have now created little robots that act like termites to build a made-to-order structure.

"Termites are the real masters of construction in the insect world," says Justin Werfel of the Wyss Institute for Biologically Inspired Engineering at Harvard University. "The largest termite mound on record was 42 feet tall."

The National Institutes of Health is teaming up with major drug companies in a new effort to identify disease-related molecules and biological processes that could lead to future medicines.

The public-private partnership is called AMP, for the "Accelerating Medicines Partnership," and it will focus first on Alzheimer's disease, Type 2 diabetes, and two autoimmune disorders: rheumatoid arthritis and lupus.
