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.

NASA is building a new space telescope with astounding capabilities. The James Webb Space Telescope, scheduled for launch in 2018, will replace the aging Hubble Space Telescope and will provide unprecedented views of the first galaxies to form in the early universe. It might even offer the first clear glimpse of an Earth-like planet orbiting a distant star.

The search for the massive star explosions called supernovae is about to get a big boost. Astronomers at Caltech in Pasadena are building a new camera that will let them survey the entire night sky in three nights.

The problem with looking for supernovae is you can't really be sure when and where to look for them. Most telescope cameras can only capture a small patch of sky at a time. But the new camera, to be mounted on a telescope at the Palomar Observatory, has a much larger field of view.

There's a project in the neighborhood of Harlem in New York that has a through-the-looking-glass quality. An organization called City Health Works is trying to bring an African model of health care delivery to the United States. Usually it works the other way around.

If City Health Works' approach is successful, it could help change the way chronic diseases are managed in poverty-stricken communities, where people suffer disproportionately from HIV/AIDS, obesity and diabetes.
