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.

Researchers in Switzerland say they've solved a nearly 100-year-old astronomical mystery by discovering what's in the wispy cloud of gas that floats in the space between the stars.

Engineers at Sandia National Laboratory have come up with what they think is a safer diagnostic test for anthrax bacteria — a test that would prevent the "bad guys" from getting their hands on this dangerous pathogen.

Sandia is home to the International Biological Threat Reduction Program. "Our interest is in safety and security of pathogens," says Melissa Finley. Finley isn't a bioweapons expert. She's a veterinarian.

A team of Indian physicists has made a mathematical model that purports to explain why ants don't have traffic jams. NPR's Joe Palca explains as part of his series, Joe's Big Idea.

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.
