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.

Three college-age scientists think they know how to solve a huge problem facing medicine. They think they've found a way to overcome antibiotic resistance.

Many of the most powerful antibiotics have lost their efficacy against dangerous bacteria, so finding new antibiotics is a priority.

It's too soon to say for sure if the young researchers are right, but if gumption and enthusiasm count for anything, they stand a fighting chance.

This summer, NPR's science desk is thinking about waves, of all kinds — ocean, gravitational, even stadium waves. But what is a wave, anyway? My editor asked me to puzzle that one out. And, to be honest, I was puzzled.

Is a wave a thing? Or is it the description of a thing? Or is it a mathematical formula that produces a curve that gives you the description of a thing?

NASA has released the first picture of Jupiter taken since the Juno spacecraft went into orbit around the planet on July 4.

The picture was taken on July 10. Juno was 2.7 million miles from Jupiter at the time. The color image shows some of the atmospheric features of the planet, including the giant red spot. You can also see three of Jupiter's moons in the picture: Io, Europa and Ganymede.

After a five-year journey through the solar system, NASA's $1.1 billion Juno mission is set to begin its orbit around Jupiter on Monday. But for the probe to be captured by the giant planet's gravity and go into the desired orbit, Juno's main engine has to fire for 35 minutes.

In 1975, I was living in San Diego and needed a job. The roommate of a friend of mine was a scientist at Scripps Clinic and Research Foundation. He said a colleague of his was looking to hire a lab technician, so I applied and got the job. The scientist I worked for was some guy from a small town in Texas. His name? Jim Allison.
