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.

For a scientist, few things are sweeter than data from an experiment that confirms a theoretical prediction.

Frequently, however, scientists don't live long enough to savor that reward. Take Albert Einstein's prediction about gravitational waves. Einstein postulated their existence in 1916, but they weren't detected until a hundred years later, long after the great physicist had died.

Pfizer is ready to ask the Food and Drug Administration to authorize emergency use of the company's COVID-19 vaccine, after an updated analysis of the clinical trial data found the vaccine to be 95% effective.

A second COVID-19 vaccine now also appears highly effective in preventing illness following exposure to the virus that causes the disease.

The biotech company Moderna Inc. said Monday that its experimental vaccine was 94.5% effective in preventing disease, according to an analysis of its clinical trial.

The news comes a week after Pfizer and BioNTech said their vaccine was more than 90% effective.

Historically, tobacco plants are responsible for their share of illness and death. Now they may help control the COVID-19 pandemic.

Two biotech companies are using the tobacco plant, Nicotiana benthamiana, as bio-factories to produce a key protein from the coronavirus that can be used in a vaccine.

Companies trying to make a vaccine for COVID-19 are trying a variety of approaches. Most involve laboratories capable of sophisticated biotechnology, but NPR's Joe Palca has this report about one approach for creating a vaccine which starts in a greenhouse.

All right, now let's work through what treatments the president is getting and what they tell us with NPR science correspondent Joe Palca. Good morning, Joe.

JOE PALCA, BYLINE: Good morning.

White House physician Sean Conley says that President Trump was doing "very well" and that the symptoms he had are resolving and improving.

Scientists and engineers in California are building a unique camera for a unique telescope.

The Rubin Observatory telescope going up on Cerro Pachón in north-central Chile can capture an unusually large swath of sky in a single image.

The camera capable of capturing those images has to be enormous. The one researchers are building at the SLAC National Accelerator Laboratory in Menlo Park, Calif., certainly is.

Under normal circumstances, it could take years — if not decades — to bring a new vaccine to market. The COVID-19 pandemic has changed all that. In May, the Trump administration launched Operation Warp Speed with the goal of delivering initial doses of a safe and effective vaccine by January 2021 — shortening the development time from years to months.

Turns out that cows may be helpful to us in the pandemic. There's a biotech company in South Dakota using cows to make antibodies for treating human disease. And lately, they've been making antibodies for COVID-19. Here's NPR's Joe Palca.

In an unusual move, the Food and Drug Administration today announced that is making it easier for doctors to try an experimental treatment for COVID-19 patients that uses plasma from people who had the disease and recovered.

There is scant evidence it works in people infected with the coronavirus, but the approach has been tried for other illnesses.

The federal government is now adding supercomputers to its tool set in the hunt for ways to stop COVID-19.
