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.

The companies say a study of more than 10,000 volunteers showed a vaccine efficacy of 95% or greater for people receiving the booster. -
Are vaccinated people who get COVID as likely to spread the infection as unvaccinated people? Scientists don't think so. -
Can a vaccinated person with a breakthrough infection infect others? Conventional wisdom says yes, but new research says it's not all that likely.

An independent committee of experts has recommended that the Food and Drug Administration should not allow Pfizer to provide a third dose of its COVID-19 vaccine to Americans older than 16.
-
The committee of independent experts advising the FDA on vaccines meets Friday. They'll be considering Pfizer's application to start offering COVID-19 vaccine boosters to all Americans older than 16.
-
Pfizer is seeking the FDA's permission to offer a third COVID-19 vaccine dose to those 16 and older. There's data that the vaccine's efficacy is waning and evidence that a booster can reverse that.
-
After vaccination, antibody levels can help predict how much protection a COVID-19 shot offers, scientists are learning. The finding could speed up the development of future vaccines. -
The lab has access to a high-security facility that Pfizer needed to prove its COVID-19 vaccine was working. Now the scientists there are testing the vaccine's effectiveness against viral variants.
