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.

It's the epic quest of campers everywhere: How do you get the perfectly toasted marshmallow? In our inaugural installment of NPR's Summer Science series, we gave some guidance on the first key ingredient: how to build the campfire. (Later this summer, we'll attempt to answer the vexing question of how to stave off brain freeze.)

Every profession has its symbols of success. For opera singers, it's performing at La Scala or the Met. For mountain climbers it's making it to the top of Everest. For scientists, if you get two papers published in the same issue of a prestigious journal like Nature, you're hot.

This summer, my big idea is to explore the big ideas of science. Instead of just reporting science as results — the stuff that's published in scientific journals and covered as news — I want to take you inside the world of science. I hope I'll make it easier to understand how science works, and just how cool the process of discovery and innovation really is.

A lot of science involves failure, but there are also the brilliant successes, successes that can lead to new inventions, new tools, new drugs — things that can change the world

Summer living is supposed to be easy — school is out, the days are long, the traffic eases. But it's not all inner tubes and lemonade: Summer can throw us some curveballs, too. How can I avoid sunburn? What can I do to stave off that brain freeze? Why do my s'mores always burn?

Fear not; NPR is here to help. As part of our new Summer Science series, we'll turn to science to tackle these vexing questions, starting with how to build the perfect campfire.
