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 forScience 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.

To Make A Spacecraft That Folds And Unfolds, Try Origami

Originally published on Thu July 17, 2014 8:40 pm

Scientists and engineers at NASA are using origami techniques to help solve a fundamental dilemma facing spacecraft designers: How do you take a big object, pack it into a small container for rocket launch, and then unpack it again once it arrives in space — making sure nothing breaks in the process.

There are smartphone apps for monitoring your diet, your drugs, even your heart. And now a Michigan psychiatrist is developing an app he hopes doctors will someday use to predict when a manic episode is imminent in patients with bipolar disorder.

People with the disorder alternate between crushing depression and wild manic episodes that come with the dangerous mix of uncontrollable energy and impaired judgment.

TESS VIGELAND, HOST:

From the studios of NPR West in Culver City, California it's ALL THINGS CONSIDERED. I'M Tess Vigeland. Let us contemplate the American teenage girl, perhaps the very first one. Apparently, there's been some scientific debate about who she is and whether she hails from the same gene sequence as what we think of as the first Americans, American Indians. And when I say gene sequence, we're not talking about Skinnies from Urban Outfitters. NPR's science correspondent Joe Palca has the story of a very old American teenage identity crisis.

AUDIE CORNISH, HOST:

From NPR News, this is ALL THINGS CONSIDERED. I'm Audie Cornish.

On the outskirts of Albuquerque, New Mexico, scientists are doing something astonishing. They're creating a white dwarf star - not a whole star but enough of one to study in minute detail. As part of his series, "Joe's Big Idea," NPR's Joe Palca introduces us to the astronomer behind this exotic project and explains why he's determined to learn all he can about this interesting stellar object.

Removing all the dangerous bacteria from drinking water would have enormous health benefits for people around the world.

The technologies exist for doing that, but there's a problem: cost.

Now a scientist at the Massachusetts Institute of Technology thinks he's on to a much less expensive way to clean up water.
