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.

Drugmakers And NIH Band Together To Speed Up Research

The National Institutes of Health is teaming up with major drug companies in a new effort to identify disease-related molecules and biological processes that could lead to future medicines.

The public-private partnership is called AMP, for the "Accelerating Medicines Partnership," and it will focus first on Alzheimer's disease, Type 2 diabetes, and two autoimmune disorders: rheumatoid arthritis and lupus.

Ancient Plague's DNA Revived From A 1,500-Year-Old Tooth

Scientists have reconstructed the genetic code of a strain of bacteria that caused one of the most deadly pandemics in history nearly 1,500 years ago.

They did it by finding the skeletons of people killed by the plague and extracting DNA from traces of blood inside their teeth.

This plague struck in the year 541, under the reign of the Roman emperor Justinian, so it's usually called the Justinian plague. The emperor actually got sick himself but recovered. He was one of the lucky ones.

Grand Canyon May Be Older (And Younger) Than You Think

The eastern Grand Canyon was about half-carved (to the level of the red cliffs above the hiker) from 15 million to 25 million years ago, an analysis published Sunday suggests. But the inner gorge was likely scooped out by the Colorado River in just the past 6 million years.

In recent years geologists have hotly debated the age of the Grand Canyon. Some think it's young (just 6 million years old), while others argue that it dates back 70 million years — to the days of dinosaurs.

Now one group says the Grand Canyon is neither young nor old. Instead, these geologists say, it's both.

Tickety-Tock! An Even More Accurate Atomic Clock

Computer networks and GPS systems are only possible because of the precision timekeeping of atomic clocks like the one above, says clockmaker and physicist Jun Ye.

Scientists announced this week that they have created the most advanced clock in the world.

The clock, described this week in the journal Nature, is so precise that it would neither lose nor gain one second in about 5 billion years of continuous operation. That's pretty good, considering that the Earth itself is only around 4.5 billion years old.

In Search For Habitable Planets, Why Stop At 'Earth-Like'?

Kepler-22b, seen in this artist's rendering, is a planet a bit larger than Earth that orbits in the habitable zone of its star. Some researchers think there might be "superhabitable" worlds that may not resemble Earth.

In their hunt for potentially habitable planets around distant stars, scientists have been so focused on finding Earth-like planets that they're ignoring the possibility that other kinds of planets might be even friendlier to life, a new report says.

So-called superhabitable worlds wouldn't necessarily look like Earth but would nonetheless have conditions that are more suitable for life to emerge and evolve, according to the study published this month in the journal Astrobiology.

A new study of volcanic rocks suggests that an ancient mural may indeed depict an erupting volcano, adding new weight to a theory that this image is a contender for the world's oldest known landscape painting or map.

Transcript

AUDIE CORNISH, HOST:

In recent years, scientists have discovered around a thousand planets orbiting other distant stars, including some called super-Earths. These planets are bigger than our rocky hole but smaller than any of our solar system's gas giants. Not much is known about these mysterious worlds.

NPR is Nell Greenfieldboyce reports on new evidence that one super-Earth is shrouded in clouds.

Bon Voyage, Voyager: Old Friends Take Stock

NASA/JPL-Caltech

Originally published on Tue December 31, 2013 9:37 am

For the scientists who have emotionally traveled with NASA's Voyager mission for decades, 2013 will be remembered as the year they knew Voyager 1 had finally become the first explorer from Earth to enter the mysterious realm of interstellar space.

Voyager 1 and its twin, Voyager 2, both blasted off in 1977, more than 35 years ago. Voyager 1 flew by Jupiter, then Saturn — and then on toward the unknown region that lies between stars.

Supercamera: More Pixels Than You Know What To Do With

When a small team of researchers recently wheeled a supercamera up to the edge of a bay at Mason Neck State Park in Northern Virginia, there was no need to point the camera at anything specific.

That's because this camera could see everything we could see, only better.

For Matthew and Brianne Wojtesta, it all started about a week after the birth of their daughter Vera. Matthew was picking up his son from kindergarten when he got a phone call.

It was their pediatrician, with some shocking news. Vera had been flagged by New York's newborn screening program as possibly having a potentially deadly disease, and would need to go see a neurologist the next day.
