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.

Some researchers who study the virus that causes Middle East respiratory syndrome got an early Christmas present: permission to resume experiments that the federal government abruptly halted in October.

Worries About Unusual Botulinum Toxin Prove Unfounded

Remember that worrisome new form of botulinum toxin we told you about in late 2013, the one that supposedly had to be kept secret out of fear it could be used as a bioweapon that would evade all of our medical defenses?

Well, as it turns out, it's not that scary after all. The antitoxin stored in the government's emergency stockpile works and would neutralize the toxin just fine.

Scientists Debate If It's OK To Make Viruses More Dangerous In The Lab

Imagine that scientists wanted to take Ebola virus and see if it could ever become airborne by deliberately causing mutations in the lab and then searching through those new viruses to see if any spread easily through the air.

Would that be OK?

Earliest Human Engraving Or Trash From An Ancient Lunch?

An inside view of this fossil Pseudodon shell shows that the hole made by Homo erectus is exactly at the spot where the muscle attached to the shell. Poking at that spot would force the shell open.

Scientists have discovered enigmatic markings on an ancient shell that's been sitting in a museum for more than a century — and they believe this may be the oldest known example of a deliberate geometric engraving made by a human hand.

These X's Are The Same Shade, So What Does That Say About Color?

This is a re-creation of a color plate from Interaction of Color, by Josef Albers. The two X's are are exactly the same — it's the different backgrounds that make them look like very different colors.

Learning to name the colors is a ritual of childhood. At first kids have no clue; often they'll just say everything is "boo." Pretty soon, though, they can rattle off Roy G. Biv with aplomb. Still, that doesn't mean they understand what color actually is.

Mark Fairchild, who studies color and vision science at the Rochester Institute of Technology, says that even physicists get it wrong when they confidently assert that color is just a wavelength of light.

As cases of a worrisome respiratory virus continue to pop up in the Middle East, scientists who study it in the U.S. are struggling to understand how they'll be affected by a government moratorium on certain kinds of experiments.

Vincent Racaniello, who studies viruses at Columbia University, says Ebola has recently become his obsession.

"I find myself reading incessantly about Ebola when I should be doing other things," says Racaniello, host of the online show This Week in Virology, which has devoted several recent programs to Ebola.

When Reassuring Isn't: The Rush To Test Cruise Passenger For Ebola

The cruise ship Carnival Magic floats behind a catamaran off Cozumel, Mexico on Oct. 17. The ship skipped a planned stop there Friday, the cruise line says, after Mexican authorities delayed granting permission to dock.

Here's a question about the fine line between a prudent response and worrisome overkill: Is the sight of a U.S. Coast Guard helicopter hovering over a cruise ship to pick up a blood sample (which is to be tested for Ebola) a sight that should inspire feelings of reassurance, or a nagging sense that something is not quite right?

The question is still in the air after the weekend's effort to airlift a few milliliters of blood from a passenger who was on board what is now being called the Ebola Cruise.

Why Won't The Fear Of Airborne Ebola Go Away?

How many times do top officials have to say that the Ebola virus is not airborne?

A lot, apparently.

Here is President Obama Thursday: "This is not an airborne disease. It is not easy to catch."

And the day before: "It is not like the flu. It is not airborne."

And Friday, a reporter asked the inevitable question about airborne Ebola when Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, held a press briefing about nurse Nina Pham's transfer to the National Institute of Health.
