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.

Victory Or Defeat? Emotions Aren't All In The Face

Originally published on Fri November 30, 2012 7:20 pm

Can You Tell Emotion From Faces Alone? A new study suggests that when people evaluated just facial expressions — without cues from the rest of the body — they couldn't tell if the face was showing a positive or negative emotion. Enlarge this photo to see the answers.

Photos of athletes in their moment of victory or defeat usually show faces contorted with intense emotion. But a new study suggests that people actually don't use those kinds of extreme facial expressions to judge how a person is feeling.

Instead, surprisingly, people rely on body cues.

Hillel Aviezer, a psychology researcher at Hebrew University of Jerusalem in Israel, wanted to see how accurately people can read intense, real-world facial expressions — instead of the standardized, posed images of facial expressions that are usually used in lab tests.

Experiments That Keep Going And Going And Going

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.

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

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.
