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.

Palca lives in Washington, D.C, with his wife and two sons.

On a daily basis, she produces, edits and reports arts and cultural segments that air on NPR News magazines including Morning Edition and All Things Considered. Her recent stories explored the rise of public humiliation in popular culture, consumers' changing media habits and the late night TV wars.

In this position that she has held since 2003, Blair's varied work has included profiles of actor Neil Patrick Harris, rapper K'Naan, and the band Pearl Jam. She has written and produced long-form documentaries on such cultural icons as Paul Robeson and Billie Holiday. Blair oversaw the production of some of NPR's most popular special projects including "50 Great Voices," the NPR series on awe-inspiring voices from around the world and across time in, and the "In Character" series which explored famous American fictional characters. Blair is especially proud of her interview with Cookie Monster and her reporting on the 10^th anniversary of SpongeBob.

Over the years, Blair has received several honors for her work including two Peabody Awards and a Gracie.

For three and a half years, Blair lived in Paris, France, where she co-produced Le Jazz Club From Paris with Dee Dee Bridgewater, and the monthly magazine Postcard From Paris.
