Nell Greenfieldboyce

Nell Greenfieldboyce joined NPR News in January 2005 to cover the media organization's newly created technology beat for NPR's science desk. The Johns Hopkins alumna has reported on topics such as pet cloning, gene therapy, ballistics, and federal laws surrounding new technology. Her primary interest is researching how applied science and technology connects with people and culture.

Greenfieldboyce's features can currently be heard on Morning Edition and All Things Considered, but before her life at NPR she worked for magazines including U.S. News & World Report and New Scientist. After working in print for ten years, Greenfieldboyce is excited to explore the field of radio and the added effects sound can bring to a piece.

In addition to receiving her B.A. in social sciences and a M.A. in science writing from Johns Hopkins, Greenfieldboyce also taught science writing for four years at the university. Greenfieldboyce was honored for her talents with the Evert Clark/Seth Payne Award for Young Science Journalists.

Greenfieldboyce lives with her husband in Washington, D.C., and does a bit of rug-hooking in her free time, creating complicated geometric patterns out of burlap and scraps of wool.

For the scientists who have emotionally traveled with NASA's Voyager mission for decades, 2013 will be remembered as the year they knew Voyager 1 had finally become the first explorer from Earth to enter the mysterious realm of interstellar space.

Voyager 1 and its twin, Voyager 2, both blasted off in 1977, more than 35 years ago. Voyager 1 flew by Jupiter, then Saturn — and then on toward the unknown region that lies between stars.

For Matthew and Brianne Wojtesta, it all started about a week after the birth of their daughter Vera. Matthew was picking up his son from kindergarten when he got a phone call.

It was their pediatrician, with some shocking news. Vera had been flagged by New York's newborn screening program as possibly having a potentially deadly disease, and would need to go see a neurologist the next day.

Evolution is relentless process that seems to keep going and going, even when creatures live in a stable, unchanging world.

That's the latest surprise from a unique experiment that's been underway for more than a quarter-century.

Scientists have used some new tricks and old dogs to show that thousands of years ago, wolves may have first become man's best friend in Europe.

Researchers extracted DNA from ancient wolf or dog fossils and compared it with DNA from modern dog breeds and wolves. Until recently, labs didn't have the kind of genetic tools they'd need to work with such old dog DNA and do this kind of detailed comparison.

Galaxy Quest: Just How Many Earth-Like Planets Are Out There?

A team of planet hunters estimates that about 22 percent of the sun-like stars in our galaxy may have planets about the size of Earth that are bathed in similar amounts of sunlight — and potentially habitable.

That's the conclusion of a new analysis of observations taken by NASA's Kepler Space Telescope, which was launched in 2009 to hunt for potentially habitable Earth-like planets around other stars.
