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.

A new era for living in space may be about to start.

A prototype habitat is headed to the International Space Station for a two-year trial. What makes the module unique is it's launched folded up, and it's inflated to its full size once in orbit.

On March 10, Rep. Sheila Jackson Lee held a news conference at the Good Neighbor Healthcare Center in the part of Houston she represents. The mayor and a bevy of other state and local officials stood behind her.

One of the most puzzling astronomical discoveries of the past decade has just gotten a little bit clearer. Astronomers still don't know what's producing the brief, powerful bursts of radio waves they've been detecting, but for the first time, they've been able to see where one of them is coming from.

Astronomers first detected these so-called fast radio bursts in 2007. Until now, all 16 FRBs that have been reported have been found by combing through archival data.

If this were a Sherlock Holmes story, its title would surely be "The Case of the Disappearing Quasar."

Lithium-ion batteries are extremely popular because they are lightweight and pack a lot of power.
