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.

NASA has announced the names of the astronauts who will be the first people in history to ride to orbit in private space taxis next year, if all goes as planned.

Leaders can have many different styles — just compare President Donald Trump to Malala Yousafzai to your boss or the coach of your kid's soccer team.

Many spiders fly long distances by riding "balloons" of silk, and a new study suggests that they're propelled by more than just the wind.

Electric fields at strengths found in nature can also trigger the spiders' ballooning behavior. And electrostatic forces can lift up the spiders even when the air is still, according to a newly published report in the journal Current Biology.

Rhino embryos created in a lab are raising hopes that high-tech assisted reproduction may help save the northern white rhino, the most endangered mammal in the world.

Only two of these rhinos are still alive, both females living in a sanctuary in Kenya and protected around the clock by armed guards.

New genetic tools are making it easier and cheaper to engineer viruses and bacteria, and a report commissioned by the Department of Defense has now ranked the top threats posed by the rapidly advancing field of "synthetic biology."

One of the biggest concerns is the ability to recreate known viruses from scratch in the lab. That means a lab could make a deadly virus that is normally kept under lock and key, such as smallpox.

A huge study on the possible health benefits of drinking alcohol will be completely shut down, because its credibility was compromised by frequent and early interactions between alcohol industry executives, scientists and government officials.

Honeybees understand that "nothing" can be "something" that has numerical meaning, showing that they have a primitive grasp of the concept of zero.

That's according to a newly published study in Science, which shows that bees possess a mathematical ability once thought to exist only in dolphins, primates, birds and humans who are beyond the preschool years.

Suicide rates have increased in nearly every state over the past two decades, and half of the states have seen suicide rates go up more than 30 percent.

Suicide is a major public health issue, accounting for nearly 45,000 deaths in 2016 alone. That is why the Centers for Disease Control and Prevention in Atlanta decided to take a comprehensive look at suicides from 1999 to 2016.

The asteroid impact that ended the age of the dinosaurs also released so much carbon dioxide into the atmosphere that the planet warmed up by about 5 degrees Celsius — and the hot spell persisted for roughly 100,000 years.

That's according to a new study in the journal Science that offers a cautionary tale about how Earth's climate will react to the carbon dioxide that's being pumped into the atmosphere now by the burning of fossil fuels.

Chimps owned by the National Institutes of Health should be moved from research facilities to retirement sanctuaries unless that relocation is "extremely likely" to shorten their lives, a report issued Friday says.

"Chimpanzees should be relocated to the federal sanctuary system unless relocation would place the chimpanzee's life, safety, and welfare at extreme risk," says the report from a working group convened by the NIH to examine the safety of transferring chimps to retirement homes.
