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.

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.

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.

The global race for a coronavirus vaccine is on. And around the world, hopes for a vaccine are high.

(SOUNDBITE OF MONTAGE)

Most public health experts agree that widespread testing will be needed to bring the COVID-19 pandemic under control. But for now, most coronavirus tests require specialized laboratories and high-tech equipment to process them.

Researchers at the McGovern Institute for Brain Research at MIT hope to change that with a simpler test that could conceivably be done in someone's kitchen.

The pharmaceutical giant Pfizer has begun testing a new coronavirus vaccine in the United States. The initial trial will involve 360 volunteers, and the first subjects have already received injections.

The vaccine was developed in a partnership between Pfizer and the German biotech company BioNTech. In addition to the U.S. trials, there will be some 200 patients enrolled in trials in Germany.

There are more than 2,000 active satellites orbiting Earth. At the end of their useful lives, many will simply burn up as they reenter the atmosphere. But some will continue circling as "zombie" satellites — neither alive nor quite dead.

"Most zombie satellites are satellites that are no longer under human control, or have failed to some degree," says Scott Tilley.

Tilley, an amateur radio operator living in Canada, has a passion for hunting them down.

A panel of experts convened by the National Institute of Allergy and Infectious Diseases recommends against doctors using a combination of hydroxychloroquine and azithromycin for the treatment of COVID-19 patients because of potential toxicities.

"The combination of hydroxychloroquine and azithromycin was associated with QTc prolongation in patients with COVID-19," the panel said.

QTc prolongation increases the risk of sudden cardiac death.

Being able to test for coronavirus infections is a critical component to reopening society — even a little bit — after the initial wave of COVID-19. So there is an urgent need for faster, cheaper tests than the ones available at present.

Two of the world's largest vaccine manufacturers are joining forces to develop a new vaccine to prevent COVID-19.

Usually, the pharmaceutical behemoths GlaxoSmithKline and Sanofi are competitors, but in a conference call with reporters, GSK CEO Emma Walmsley said the coronavirus pandemic represented "an unprecedented global health threat," and, therefore, required new ways of doing business.

Gilead Sciences is reporting some preliminary results from the use of its antiviral drug remdesivir in treating patients with COVID-19.

The study, published Friday by the New England Journal of Medicine, evaluated the response of 53 patients given remdesivir on a compassionate use basis.

Thirty-six showed clinical improvement, while eight got worse. Patients who were not on a ventilator tended to do better than those who were. Seven of the 53 died.
