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.

When Did Humans Start Shaping Earth's Fate? An Epoch Debate

Originally published on Mon April 6, 2015 11:35 am

Humans have had such a huge impact on the Earth that some geologists think the human era should be enshrined in the official timeline of our planet.

They want to give the age of humans a formal name, just as scientists use terms like the Jurassic or the Cretaceous to talk about the age of dinosaurs.

But some researchers think that formally establishing an "Anthropocene" — as many call it — as part of the geologic time scale would be a big mistake.

NASA To Study A Twin In Space And His Brother On Earth

NASA astronaut Scott Kelly is seen inside a Soyuz simulator at the Gagarin Cosmonaut Training Center on March 4 in Star City, Russia. Kelly, along with Russian cosmonaut Mikhail Kornienko of the Russian Federal Space Agency, are scheduled for launch Friday aboard a Soyuz TMA-16M spacecraft from the Baikonur Cosmodrome in Kazakhstan.

A Russian rocket has carried a Russian cosmonaut and an American astronaut to the International Space Station, where they will live for a full year, twice as long as people usually stay.

No American has remained in space longer than 215 days. Only a few people have ever gone on space trips lasting a year or more — the longest was 437 days — and they're all Russian cosmonauts. The last year-plus stay in space occurred nearly two decades ago.

With recent news headlines proclaiming that dozens of people have been selected as finalists for a Martian astronaut corps, it might seem like a trip to this alien world might finally be close at hand.

But let's have a little reality check. What are the chances that we really will see people on the Red Planet in the next couple of decades?
