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.

You Can't See It, But You'll Be A Different Person In 10 Years

No matter how old people are, they seem to believe that who they are today is essentially who they'll be tomorrow.

That's according to fresh research that suggests that people generally fail to appreciate how much their personality and values will change in the years ahead — even though they recognize that they have changed in the past.

Daniel Gilbert, a psychology researcher at Harvard University who did this study with two colleagues, says that he's no exception to this rule.

Research Moratoriums And Recipes For Superbugs: Bird Flu In 2012

For scientists who study a dangerous form of bird flu, 2012 is ending as it began — with uncertainty about what the future holds for their research, but a hope that some contentious issues will soon be resolved.

NIH Moving To Revamp Funding Process For Bird Flu Research

Flu researchers may be close to ending an unusual moratorium on some controversial scientific work that has lasted almost a year.

That's because officials at the National Institutes of Health say they will be moving swiftly to finalize a new process for deciding whether or not to fund proposed experiments that could potentially create more dangerous forms of the bird flu virus H5N1.

NIH Revisits Debate On Controversial Bird Flu Research

On Tuesday, the National Institutes of Health in Maryland is holding a second day of talks about whether and how to continue funding some controversial scientific experiments.

Back in January, virologists agreed to temporarily stop research that was creating new forms of bird flu because critics argued that the work was too dangerous. NIH officials are now seeking input from scientists and the public about how to proceed.

50 Years After First Interplanetary Probe, NASA Looks To Future

Fifty years ago, on Dec. 14, 1962, reporters gathered for a press briefing at NASA headquarters and heard an unearthly sound: radio signals being beamed back by a spacecraft flying within 22,000 miles of Venus.

The Mariner 2 mission to Venus was the first time any spacecraft had ever gone to another planet.

These days, vivid photographs showing scenes from all around the solar system are so ubiquitous that people might easily forget how mysterious our planetary neighbors used to be.

Is Another Moon Mission Written In The Stars?

Apollo 17 was the sixth and final Apollo mission to the moon. Here, lunar module pilot Harrison "Jack" Schmitt, Cmdr. Eugene Cernan and command module pilot Ron Evans pose in the lunar vehicle.

On Dec. 7, 1972, NASA launched its final human mission to the moon. Forty years later, Apollo 17 commander Eugene Cernan says he'd love to give up his claim to fame as "the last man on the moon."

"I'd like to be able to shake the hand of that young man or young woman who replaces me in that category," Cernan told NPR. "But unfortunately, the way things have gone and the way things are looking for the future, at least the near-term future, that won't happen in my lifetime. And that truly is disappointing."

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

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.
