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.

Climate Change Adjustments Must Be Fast And Major, U.N. Panel Says

The world must cut its greenhouse gas emissions to meet its goals, climate experts said Sunday. Members of the Intergovernmental Panel on Climate Change (left to right) Youba Sakona, Ramon Pichs Madruga, Ottmar Edenhofer and Rajendra Pachauri hold copies of their new report in Berlin.

A new report from the United Nations' panel on climate change says major action is needed, and fast, if policymakers want to limit global warming to acceptable levels.

There's an international target to control climate change: keeping the global temperature rise to just 2 degrees Celsius above pre-industrial levels — that's 3.6 degrees Fahrenheit. The Intergovernmental Panel on Climate Change now says it's technically possible to meet that goal. But doing so will require rapid, large-scale shifts in energy production and use.

The Dutch virologist accused of engineering a dangerous superflu a few years ago is back with more contentious research.

In 2011, Ron Fouchier and his team at Erasmus Medical Center took the H5N1 flu virus and made it more contagious. Now the team has published another study with more details on the exact genetic changes needed to do the trick.

Smithsonian's Air And Space Museum To Get $30 Million Spiffier

Where's the moon rock? Curators say national treasures are often overlooked in the museum's current display, which hasn't changed much since 1976.

Throngs of museum-goers mill through the grand entrance hall of the Smithsonian's National Air and Space Museum in Washington, D.C., every day, gawking at such treasures as the Apollo 11 capsule that carried Neil Armstrong's crew to the moon and back, as well as Charles Lindbergh's Spirit of St. Louis airplane.

But the famous Milestones of Flight exhibit hasn't significantly changed since the museum opened in 1976.

NASA is hoping to soon venture out farther into space than ever before. But these long journeys mean astronauts could face greater risks to their physical and mental health than the space agency currently allows.

Now, an independent group of experts convened by the Institute of Medicine, the health arm of the National Academy of Sciences, has weighed in on how NASA should make decisions about the kinds of risks that are acceptable for missions that venture outside low Earth orbit or extend beyond 30 days.

New Dwarf Planet Found At The Solar System's Outer Limits

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.
