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.

Experiments That Keep Going And Going And Going

William Beal, standing at center, started a long-term study on seed germination in 1879. He buried 20 bottles with seeds in them for later researchers to unearth and plant.

A biologist who has been watching a dozen bottles of bacteria evolve for nearly a quarter of a century is hoping he can find someone to keep his lab experiment going long after he dies.

Meanwhile, just by coincidence, a botanist who works across campus is carefully tending an experiment that started before he was born, all the way back in 1879.

These two researchers, both at Michigan State University in East Lansing, represent different sides of an unusual phenomenon in science: experiments that outlive the people who started them.

Ingredients For A Homestyle Thanksgiving, 200 Miles Above The Earth

For Thanksgiving, NASA's space food experts always try to make sure astronauts get to enjoy traditional holiday fare, even if its not exactly home cooking. And being so far from home, astronauts can get pretty attached to their comfort foods.

This year, Kevin Ford, the commander of Expedition 34 and currently working at the International Space Station, says he has the ingredients to make one favorite Thanksgiving dish the NASA nutritionists may not have anticipated: Candied yams with marshmallows.

The yams are thermostablized and come in a plastic pouch.

When Fetuses Yawn In The Womb

Could that be a yawn? An ultrasound scan catches an opened-mouth fetus.

Why people yawn is a mystery. But yawning starts in the womb.

Past studies have used ultrasound images to show fetuses yawning, but some scientists have argued that real yawns were getting confused with fetuses simply opening their mouths.

So Nadja Reissland, a researcher at the University of Durham in the United Kingdom, used a more detailed ultrasound technique to get images of fetal faces that could distinguish a true yawn from just an open mouth.

Move Over, Parrot: Elephant Mimics Trainer At Zoo

Koshi, an elephant, makes sounds that imitate Korean words.

Scientists say an Asian elephant at a South Korean zoo can imitate human speech, saying five Korean words that are readily understood by people who speak the language.

The male elephant, named Koshik, invented an unusual method of sound production that involves putting his trunk in his mouth and manipulating his vocal tract.

"This is not the kind of sound that Asian elephants normally make, and it's a dead-on match of the speech of his trainers," says Tecumseh Fitch of the University of Vienna in Austria.

Two Americans Share Nobel Prize In Chemistry

Originally published on Wed October 10, 2012 6:57 pm

Two Americans have won the 2012 Nobel Prize in Chemistry. Robert Lefkowitz and Brian Koblika were awarded the prize for their work on protein receptors that tell cells what's going on around the human body. Their research has allowed drug makers to develop medication with fewer side effects. The pair with share the $1.2 million award.

Debate Heats Up About Contentious Bird Flu Research

When a case of the potentially lethal H5N1 bird flu was found in British poultry in 2007, Dutch farmers were told to keep their poultry away from wild birds by closing off outdoor areas with wire mesh.

What was supposed to be a 60-day moratorium on certain experiments involving lab-altered bird flu has now lasted more than eight months. And there's no clear end in sight.

Researchers still disagree on how to best manage the risks posed by mutant forms of highly pathogenic H5N1 bird flu. The altered viruses are contagious between ferrets, which are the lab stand-in for humans. The fear is that these germs could potentially cause a deadly flu pandemic in people if they ever escaped the lab.

Scientist Cleared In Polar Bear Controversy

Polar bears in the Beaufort Sea in northern Alaska. Scientist Charles Monnett caused a stir with a 2006 report on polar bears that were drowning, apparently owing to a lack of ice.

A long, controversial investigation of a polar bear scientist has ended with his government employer saying it does not look like he engaged in any scientific misconduct.

Charles Monnett is a wildlife researcher with the Bureau of Ocean Energy Management, part of the Department of the Interior. He and a colleague, Jeffrey Gleason, wrote an influential 2006 report describing apparently drowned polar bears floating in the Arctic, which they saw during a routine aerial survey of whales.

NASA's Curiosity Finds Water Once Flowed On Mars

NASA says it has found proof that water shaped the rocks on the left, in a photograph taken by the Mars rover Curiosity (left). For comparison, the agency released an image of rocks from Earth (right).

NASA's newest Mars rover, Curiosity, has snapped photos of rocky outcroppings that jut out from the alien soil, and scientists say they look like the remnants of an ancient stream bed where water once flowed on the surface of the red planet.

The exposed rocks look like broken slabs of concrete sidewalk, about four inches thick, and are made of rounded bits of gravel in a sandy matrix. The rock has eroded a little bit, and some of the smooth pebbles — about the size of M&M candies — have fallen down into a little pile.
