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.

Jupiter Or Bust, But First A Quick Fly-By Of Home

After traveling for more than two years and some 1 billion miles, NASA's Juno mission to Jupiter is back where it started. Almost. At 3:21 p.m. ET Wednesday, the Juno space probe will be 347 miles away from Earth, just above the southern tip of Africa.

(As an aside, at around 11:30 a.m. ET, it was more than 90,000 miles away.)

Try to imagine someone who is supremely calm while at the same time bursting with energy, and you've got a pretty good idea of what Jim Olson is like.

He's a cancer researcher, physician, cyclist, kayaker and cook, not always in that order. He approaches each activity with incredible passion.

Perhaps one of the most uncomfortable things a doctor has to tell patients is that their medical problems are iatrogenic. What that means is they were caused by a doctor in the course of the treatment.

Sometime these iatrogenic injuries are accidental. But sometimes, because of the limits of medical technology, they can be inevitable. Now, a medical researcher in Seattle thinks he has a way to eliminate some of the inevitable ones.

Trypophobia may be moving out of the urban dictionary and into the scientific literature.

A recent study in the peer-review journal Psychological Science takes a first crack at explaining why some people may suffer from a fear of holes.

Trypophobia may be hard to find in textbooks and diagnostic manuals, but a brief Web search will show that plenty of people appear to have it.
