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.

Taking hydroxychloroquine after being exposed to someone with COVID-19 does not protect someone from getting the disease.

That's the conclusion of a study published Wednesday involving 821 participants. All had direct exposure to a COVID-19 patient, either because they lived with one, or were a health care provider or first responder.

COVID-19 isn't the first health crisis the United States has faced that experts say a vaccine will be needed to resolve: In the 1950s, people lived in fear their children might be stricken with infantile paralysis, better known as polio — and they were eager for scientists to find a solution.

"There was a lot of anxiety," says New York University medical historian David Oshinsky, author of Polio, An American Story.

Encouraging news today about the prospects for a vaccine to prevent COVID-19. NPR science correspondent Joe Palca has more.

NPR's science correspondent answers listener questions about the latest in the hunt for a coronavirus vaccine.

A vaccine manufacturer is reporting preliminary data suggesting its COVID-19 vaccine is safe, and appears to be eliciting in test subjects the kind of immune response capable of preventing disease.

Moderna, Inc., of Cambridge, Mass., developed the vaccine in collaboration with the National Institute of Allergy and Infectious Diseases. The results reported Monday come from an initial analysis of a Phase I study primarily designed to see if the vaccine is safe.

NOEL KING, HOST:

NPR's science correspondent answers listener questions about the antiviral drug remdesivir and other COVID-19 treatment possibilities.

Most health experts agree that the need for a vaccine to prevent COVID-19 is clear.

"To return to a semblance of previous normality, the development of SARS-CoV-2 vaccines is an absolute necessity" is how a perspective in Science magazine puts it.

While authorities across the U.S. struggle to make policy without any hard numbers for how many people are actually infected with the coronavirus, Oregon State University has launched a project to change that — at least for one small city.
