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 for Science 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.

Let's say you're a scientist, and you've invented what you think is a useful treatment for pain. But you have a problem. You don't have the money to go through the regulatory approval process. Should you try to sell it to consumers anyway, and run the risk of being accused of selling snake-oil?

MARY LOUISE KELLY, HOST:

After 13 years in orbit around Saturn, NASA's Cassini spacecraft is about to plunge itself into the planet's atmosphere and disintegrate. NASA decided to put an end to the mission on Friday because the probe is almost out of fuel.

Cassini has provided exquisite details about the second-largest planet in our solar system.

Sometimes the true value of an invention isn't obvious until people start using it.

Consider what happened to inventor Nate Ball and his powered ascender. About 15 years ago, Ball was an undergraduate at the Massachusetts Institute of Technology when the U.S. Army approached MIT with a request: Can somebody build a powered device that can pull somebody up a rope, like Batman does?

There is a lifesaving drug that owes its existence to moldy hay, sick cows and rat poison.

When you want to change the world, a good invention helps. But that is just the start.

Take the story of Mike Davidson and Mike Smith: They wanted to change the world of dental hygiene with a new kind of toothbrush.

Three years ago, their brushes were rolling off the assembly line, ready for consumers. But then the pair ran into a business buzz saw, and it changed the way they saw the business of invention forever.

A prototype of what could be the next generation of space stations is currently in orbit around the Earth.

The prototype is unusual. Instead of arriving in space fully assembled, it was folded up and then expanded to its full size once in orbit.
