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.

Atop A Hawaiian Mountain, A Constant Sniff For Carbon Dioxide

Researchers use the 120-foot tower atop Mauna Loa in Hawaii to collect air samples and measure the amount of carbon dioxide in the atmosphere. Mauna Kea looms in the distance.

Climate scientists have a good reason to want to get away from it all. To get an accurate picture of the amount of carbon dioxide in the Earth's atmosphere, you have to find places where the numbers won't be distorted by cities or factories or even lots of vegetation that can have a major local impact on CO2 concentrations.

Wake Up And Smell The Tuna? Sunrise At Honolulu's Fish Auction

Among the 50,000 pounds of fish at the Honolulu auction last Friday was this opah, or moonfish, Lampris regius.

If you are up at 5 in the morning in Honolulu and are wondering what to do, I have a suggestion: Head over to Pier 38 and watch the Honolulu Fish Auction. It's quite a scene.

Getting up at 5 may seem a bit extreme, but for recent arrivals to Hawaii from the East Coast of the mainland — as I was last Friday — the six-hour time difference makes waking up early easy, if not inevitable.

Kepler Telescope Spots 3 New Planets In The 'Goldilocks Zone'

The small squares superimposed on this image of the Milky Way galaxy show where in the sky the Kepler telescope is hunting for Earth-like planets. Kepler, which launched in 2009, has identified more than 100 planets.

Astronomers have found three planets orbiting far-off stars that are close to Earth-sized and in the "habitable zone": a distance from their suns that makes the planets' surfaces neither too hot nor too cold, but just right.

One of the three planets orbits a star with the prosaic name Kepler-69.

Wanna Play? Computer Gamers Help Push Frontier Of Brain Research

This image represents a chunk, or "cube," of brain. Each different color represents a different neuron, and the goal of the EyeWire game is to figure out how these tangled neurons connect to each other. Players look at a slice from this cube and try to identify the boundaries of each cell. It isn't easy, and it takes practice. You can try it for yourself at eyewire.org.

People can get pretty addicted to computer games. By some estimates, residents of planet Earth spend 3 billion hours per week playing them. Now some scientists are hoping to make use of all that human capital and harness it for a good cause.

Right now I'm at the novice level of a game called EyeWire, trying to color in a nerve cell in a cartoon drawing of a slice of tissue. EyeWire is designed to solve a real science problem — it aims to chart the billions of nerve connections in the brain.
