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 is also the founder of NPR Scicommers – A science communication collective.

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, 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's 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. In 2019, Palca was elected to the American Academy of Arts and Sciences for outstanding achievement in journalism.

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.

Locusts are not just a biblical plague. They're swarming around the world. Still. Again.

According to the Food and Agriculture Organization of the United Nations, the desert locust situation is serious in Yemen and at the Indo-Pakistan border.

What To Feed Locusts

Aug 9, 2019

RACHEL MARTIN, HOST:

Here at NPR, we've been trying to do more stories that answer people's questions about issues they face in their daily lives. NPR's Joe Palca apparently didn't get the memo because he's got a story with the answer to a question almost nobody has - what to feed a colony of captive locusts.

JOE PALCA, BYLINE: To answer that question, it helps to go to Tempe, Ariz.

RICK OVERSON: We are inside one of the two main rooms of the locust lab here at Arizona State University. We affectionately refer to it as Hopper Town.

STEVE INSKEEP, HOST:

A telescope now under construction promises to revolutionize astronomy. It's being built atop a mountain in Chile, in the Andes. It's called the LSST. It is a survey telescope taking wide-angle views of the sky. And this telescope is expected to spot rare events that previously have been hard or impossible to find. NPR science correspondent Joe Palca toured the telescope's construction site.

ARI SHAPIRO, HOST:

There's a telescope high up in the mountains of Chile that's looking for signals from the earliest moments of the universe. Finding these signals would be key to explaining how the universe began. NPR's Joe Palca has just returned from a visit to the telescope, and he has this report on a remarkable facility in a remarkable location.

JOE PALCA, BYLINE: The telescope is called CLASS. It's located on top of Cerro Toco in the Atacama Desert, one of the driest places on Earth. And at 17,000 feet, it's one of the highest telescopes in the world.
