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.

DAVID GREENE, HOST:

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.

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.

When Neil Armstrong set foot on the moon 50 years ago, it was an inspiring moment for people around the world.

But another kind of explorer is responsible for much of the modern enthusiasm for space exploration.

"Since the days of Apollo, the greatest adventures in space have been these robots that have gone all over the solar system," says Emily Lakdawalla, a self-described planetary evangelist at the Planetary Society.

MICHEL MARTIN, HOST:

Much of South America experienced a solar eclipse this week. NPR's Joe Palca went to Chile to see it in its totality. And because half of the world's major telescopes are in Chile, he decided to stick around and see what researchers are studying. And Joe Palca is with us now from 17,000 feet.

Hi, Joe.

JOE PALCA, BYLINE: Hey, Michel. How are you doing?

MARTIN: OK. So where are you right now, exactly?

MARY LOUISE KELLY, HOST:

The path of a total solar eclipse passed over a major observatory in Chile this afternoon. NPR science correspondent Joe Palca was there. He saw the eclipse from the Cerro Tololo Inter-American Observatory from where he joins us now live.

Hey, Joe.

JOE PALCA, BYLINE: Hey, Mary Louise. How are you doing?

KELLY: I'm well. Thank you. And I'm thinking, I have actually - I have seen a couple of total solar eclipses. I have never seen one from an observatory, which I'm guessing is a pretty darn good place to see one.

RACHEL MARTIN, HOST:

There's a mole stuck in the ground on Mars - not the small, furry animal but a probe on NASA's Mars InSight lander called the mole. It's a probe that was supposed to go 15 feet beneath the Martian surface, but it got stuck after only going one.

NPR's Joe Palca has more.

Small drones can do big jobs: Firefighters can use them to find hot spots in blazes, environmental monitors can find the source of hazardous chemical leaks. One just delivered a human kidney for transplant surgery.

But it takes lots of power to spin four helicopter blades fast enough to keep a quadcopter-type drone in the air. Most can only stay aloft for about 30 minutes.

A team of astronomers led by an undergraduate student in Texas has discovered two planets orbiting stars more than 1,200 light-years from Earth.

Astronomers already knew of about 4,000 exoplanets, so finding two more might not seem like huge news. But it's who found them and how that's getting attention.

Is there an efficient way to tinker with the genes of plants? Being able to do that would make breeding new varieties of crop plants faster and easier, but figuring out exactly how to do it has stumped plant scientists for decades.

Now researchers may have cracked it.

Modifying the genetics of a plant requires getting DNA into its cells. That's fairly easy to do with animal cells, but with plants it's a different matter.
