Joe Palca

Joe Palca is a science correspondent for NPR. Since joining NPR in 1992, Palca has covered a range of science topics — everything from biomedical research to astronomy. He is currently focused on the eponymous series, "Joe's Big Idea." Stories in the series explore the minds and motivations of scientists and inventors.

Palca began his journalism career in television in 1982, working as a health producer for the CBS affiliate in Washington, DC. In 1986, he left television for a seven-year stint as a print journalist, first as the Washington news editor for Nature, and then as a senior correspondent for Science Magazine.

In October 2009, Palca took a six-month leave from NPR to become science writer in residence at the Huntington Library and The Huntington Library, Art Collections, and Botanical Gardens.

Palca has won numerous awards, including the National Academies Communications Award, the Science-in-Society Award of the National Association of Science Writers, the American Chemical Society James T. Grady-James H. Stack Award for Interpreting Chemistry for the Public, the American Association for the Advancement of Science Journalism Prize, and the Victor Cohn Prize for Excellence in Medical Writing.

With Flora Lichtman, Palca is the co-author of Annoying: The Science of What Bugs Us (Wiley, 2011).

He comes to journalism from a science background, having received a Ph.D. in psychology from the University of California at Santa Cruz where he worked on human sleep physiology.

Three engineering undergrads at Rice University gave a teenager with a rare genetic disease something he'd always wished for: the ability to turn off the light in his room.

It may not seem like much, but for 17-year-old Dee Faught, it represents a new kind of independence.

Bryan Shaw never expected to write a research paper about a rare eye cancer.

Try to imagine someone who is supremely calm while at the same time bursting with energy, and you've got a pretty good idea of what Jim Olson is like.

He's a cancer researcher, physician, cyclist, kayaker and cook, not always in that order. He approaches each activity with incredible passion.

But to really understand Olson, you have to watch him in action with patients.

Perhaps one of the most uncomfortable things a doctor has to tell patients is that their medical problems are iatrogenic. What that means is they were caused by a doctor in the course of the treatment.

Sometime these iatrogenic injuries are accidental. But sometimes, because of the limits of medical technology, they can be inevitable. Now, a medical researcher in Seattle thinks he has a way to eliminate some of the inevitable ones.

There's a hole in the sun's corona. But don't worry — that happens from time to time.

"A coronal hole is just a big, dark blotch that we see on the sun in our images," says Dean Pesnell, project scientist for NASA's Solar Dynamics Observatory. "We can only see them from space, because when we look at them [through] a regular telescope, they don't appear."

Late summer tends to be a slow month for news. But at All Things Considered, we put on a two hour program, no matter what. So — without a trace of irony — one of our science correspondents offered to help fill some holes in the show with a series of stories about holes. In this edition: Black holes.

From NPR News, this is ALL THINGS CONSIDERED. I'm Robert Siegel.

A program such as ours is timed to the exact second, and occasionally, there are small holes when our mix of news and features doesn't quite fill up our two-hour slot.

The big idea behind Joe's Big Idea is to report on interesting inventions and inventors. When I saw the headline "An Environmentally Friendly Battery Made From Wood," on a press release recently, I figured it fit the bill, so went to investigate.

Climate scientists have a good reason to want to get away from it all. To get an accurate picture of the amount of carbon dioxide in the Earth's atmosphere, you have to find places where the numbers won't be distorted by cities or factories or even lots of vegetation that can have a major local impact on CO2 concentrations.

Astronomers have found three planets orbiting far-off stars that are close to Earth-sized and in the "habitable zone": a distance from their suns that makes the planets' surfaces neither too hot nor too cold, but just right.

One of the three planets orbits a star with the prosaic name Kepler-69.

What do you do when you're a scientist and you have no job and no money for your research? If you're Ethan Perlstein, you try crowd funding. He raised $25,000 to investigate where the drug methamphetamine is stored in the brain.
