It's not been a good year for Florida's citrus industry. The U.S. Department of Agriculture reports that, for the second year running, the orange crop is expected to be almost 10 percent lower than the previous year.

The culprit is citrus greening, a disease that has devastated Florida's oranges and grapefruits, and has now begun to spread in Texas and California.

Stretch Or Splat? How A Black Hole Kills You Matters ... A Lot

Never mind holiday stress. Steer clear of black holes, or risk "spaghettification" — or worse.

It could rightly be called the most massive debate of the year: Physicists are locked in an argument over what happens if you fall into a black hole.

On one side are those who support the traditional view from Albert Einstein. On the other, backers of a radical new theory that preserves the very core of modern physics by destroying space itself.

Ranchers and hunters strongly opposed the move and now the federal government wants to take the gray wolf off the endangered species list. NPR's Elizabeth Shogren reports, this time, it is the scientists who are protesting loudly.

To Make Intersections Smarter, We Need Cars To Be Smarter, Too

Originally published on Fri December 27, 2013 6:15 pm

ROBERT SIEGEL, HOST:

From NPR News, this is ALL THINGS CONSIDERED. I'm Robert Siegel.

Car companies have already begun to design cars that can drive themselves. But to make these smart cars really useful, they'll also need smart roads. As part of his series, "Joe's Big Idea," NPR science correspondent Joe Palca has this story about some computer scientists who were designing a smart traffic intersection. How smart? Well, it can keep traffic flowing at least 10 times faster than old-fashioned intersections.
