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.

Space shuttle Endeavour begins a kind of farewell tour this week. The shuttle will set off on a cross-country trip to its retirement home, flying from Florida to Los Angeles on the back of a modified jumbo jet.

Along the way, the spaceship will stop off in Houston, home of NASA's Mission Control and, weather permitting, fly over NASA centers and various landmarks in cities that include San Francisco and Sacramento.

After 35 Years, Voyager Nears Edge Of Solar System

In addition to surveying the planets, the Voyager mission also spent time studying the planets' satellites, or moons. This mosaic image, taken in 1989, shows Neptune's largest satellite, Triton. Triton has the coldest surface temperature known anywhere in the solar system.

The Voyager 1 spacecraft's 35th anniversary is proving to be unexpectedly exciting, as scientists gathered this week to examine new hints that the spacecraft is on the verge of leaving our solar system.

Voyager 1 is now more than 11 billion miles away from Earth. It blasted off in September 1977, on a mission to Jupiter and Saturn. But it also carried a Golden Record filled with music and the sounds of our planet, in case it encountered intelligent life as it moved out toward the stars.

Subtracting Calories May Not Add Years To Life

Scientists have known for decades that lab rats and mice will live far longer than normal if they're fed a super-low-calorie diet, and that's led some people to eat a near-starvation diet in the hopes that it will extend the human life span, too.

But a new study in monkeys suggests they may be disappointed.

The long-awaited results of this study, which started back in 1987, show that rhesus monkeys fed a diet with 30 percent fewer calories than normal did not live unusually long lives.

The only remaining laboratory of one of the greatest American inventors may soon be purchased so that it can be turned into a museum, thanks to an Internet campaign that raised nearly a million dollars in about a week.

The lab was called Wardenclyffe, and it was built by Nikola Tesla, a wizard of electrical engineering whose power systems lit up the Chicago World's Fair in 1893 and harnessed the mighty Niagara Falls.

Swarming Up A Storm: Why Animals School And Flock

A school of Blue Tang fish swimming together off the Caribbean island of Bonaire. It has long been assumed that the schooling behavior of fish evolved in part to protect animals from being attacked by predators.

By tricking live fish into attacking computer-generated "prey," scientists have learned that animals like birds and fish may indeed have evolved to swarm together to protect themselves from the threat of predators.

"Effectively, what we're doing here is we're getting predatory fish to play a video game," says Iain Couzin, who studies collective animal behavior at Princeton University. "And through playing that game, through seeing which virtual prey items they attack, we can get a very deep understanding of as to how behavioral interactions among prey affect their survival."

A federal investigation into two researchers who wrote a famous report on drowned polar bears is finally over, according to their lawyer.

But the scientists still haven't been allowed to see a copy of the investigation report or its conclusions, says attorney Jeff Ruch of Public Employees for Environmental Responsibility.

Critics have charged that the two-year investigation was a witch hunt into researchers whose work had political implications.

NIH Official Calls For Extension Of Moratorium On Bird Flu Experiments

National Institute of Allergy and Infectious Diseases Director Dr. Anthony Fauci said a voluntary halt to bird flu research should stay in effect.

A voluntary moratorium on certain experiments involving forms of bird flu altered in laboratories should continue until there can be more public discussion of safety concerns, a prominent government official told flu researchers at a meeting in New York City Tuesday.

What Does The Future Hold For Bird Flu Research?

In a hotel ballroom in New York City, a couple hundred flu researchers watched with interest Monday as a government official ran down a list of seven kinds of experiments that could raise special security risks.

The official noted that one item on the list was any experiment that could make an infectious agent more transmissible, or contagious. "It wouldn't take long for this audience to come up with an example of that," he noted wryly.

Bird Flu Researchers To Meet About Research Moratorium

Chickens are under quarantine in Tepatitlan, Jalisco State, Mexico. The Mexican government declared a national animal health emergency July 2 in the face of an aggressive bird flu epidemic that has infected nearly 1.7 million poultry.

Top influenza researchers around the world published a statement back in January saying they would temporarily hold off on any work with contagious, lab-altered forms of a particularly worrisome form of bird flu.

The unusual voluntary moratorium was supposed to last only 60 days, but it's been more than six months. And scientists don't agree on what should happen next.

Fledgling NASA Nonprofit Starts To Liftoff

Originally published on Tue July 3, 2012 8:24 am

A new nonprofit organization that's supposed to take charge of expanding scientific research on the International Space Station has had a rocky first year but now is starting to show what it can do.

The Center for the Advancement of Science in Space just signed one agreement with a company not traditionally linked to research in space: the sporting goods company Cobra Puma Golf.
