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.

Telescope Innovator Shines His Genius On New Fields

Originally published on Thu August 23, 2012 11:23 am

Roger Angel, an astronomer at the University of Arizona, stands in front of his new project: a solar tracker. Angel wants to use the device to harness Arizona's abundant sunlight and turn it into usable energy.
Jason Millstein for NPR

You may not be familiar with the name Roger Angel, but if there were ever a scientist with a creative streak a mile wide, it would be he.

Angel is an astronomer. He's famous for developing an entirely new way of making really large, incredibly precise telescope mirrors. But his creativity doesn't stop there. He's now turned his attention to solar power, hoping to use the tricks he learned from capturing distant light from stars to do a more cost-efficient job of capturing light from the Sun.

The Mars rover Curiosity is beginning its fifth day on the red planet, and it's been performing flawlessly from the moment it landed.

That's been especially gratifying for NASA landing engineer Adam Steltzner. Last Friday, while Steltzner was still on pins and needles waiting for the landing to take place, I told the story of Steltzner's decision as a young man to give up his life as a rocker and go for a career in space engineering.

After A Historic Landing, A Postcard From The Jet Propulsion Laboratory

The newsroom at NASA's Jet Propulsion Laboratory is beginning to thin out as the Mars Science Laboratory transitions from an exciting news story, to a long duration — possibly very long duration — exploration of the geologic and environmental history of Mars.

For the reporters still in the newsroom, fatigue is beginning to set in. BBC science correspondent Jonathan Amos has been at it nonstop for 30 hours. I feel a bit guilty for stepping out and getting a few hours sleep.
