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 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 forScience 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.

Mission To Study Mars' Climate Enters Red Planet's Orbit

In this artist concept provided by NASA, the MAVEN spacecraft approaches Mars on a mission to study its upper atmosphere.

This Sunday night, we headed back to Mars: NASA's MAVEN spacecraft fired its six main engines, slowing down enough so it could be captured by the gravity of the red planet and go into orbit.

MAVEN, which stands for Mars Atmosphere and Volatile Evolution, is a distinctly un-sexy name for a project as cool as a sojourn to Mars. But whatever it's called, the probe is on a mission that should be of interest to everyone who likes living on Earth.

Some people dream of climbing Mount Everest or riding a bicycle across the country. Mike Davidson's dream has been to create the perfect toothbrush, and now he thinks he's done it.

The saga of this brush tells a lot about the passion and persistence to take an idea and turn it into a product.

Where We Learn That Artificial Eyes Really Aren't Round At All

A prosthetic eye is a work of art custom-crafted for an individual.

Almost every time reporters go out on assignment, they run across something unexpected that they just can't fit into the story they're working on.

When science correspondent Joe Palca and producer Rebecca Davis were in Boston reporting on a boy with a rare form of cancer, they found themselves in the office of Jahrling Ocular Prosthetics, a business dedicated to making artificial eyes.

Transformer Paper Turns Itself Into A Robot. Cool!

This little guy changes from flat sheet of paper to critter in about four minutes.

Every so often, a scientific paper just begs for a sexy headline.

Consider this study in the current issue of Science: "A Method for Building Self-folding Machines." A bit bland, you'll no doubt agree. A Real-Life, Origami-Inspired Transformer is how the journal's public affairs department referred to it. Now that's more like it.

Close Encounters Of The Radio Kind? Mystery Bursts Baffle Astronomers

Scientists say a brief burst of radio activity has been detected at the Arecibo radio telescope in Puerto Rico. This new report resembles previous activity detected in Australia, which has scientist debating possible causes, including solar flares, blitzars, or something even more mysterious.

Astronomers have a mystery on their hands. Two large radio telescopes, on opposite sides of the planet, have detected very brief, very powerful bursts of radio waves.

Right now, astronomers have no idea what's causing these bursts or where they're coming from. And nothing has been ruled out at the moment — not even the kind of outrageous claims you'd expect to see in tabloid headlines.

To Make A Spacecraft That Folds And Unfolds, Try Origami

Originally published on Thu July 17, 2014 8:40 pm

Scientists and engineers at NASA are using origami techniques to help solve a fundamental dilemma facing spacecraft designers: How do you take a big object, pack it into a small container for rocket launch, and then unpack it again once it arrives in space — making sure nothing breaks in the process.
