Salad producers haven't succeeded in banishing E. coli and other dangerous microbes from fresh greens, though they've tried hard. As we've reported before, it's a major challenge to both growers and the environment. But one scientist thinks he's making progress – with a spinach spa that zaps bad bugs with ultrasound.

Call it the ponderous effect of the holidays, but today I'd like to share some reflections on our search for meaning.

Have you ever wondered whether music conductors actually influence their orchestras?
They seem important. After all, they're standing in the middle of the stage and waving their hands. But the musicians all have scores before them that tell them what to play. If you took the conductor away, could the orchestra manage on its own?
Most people try to avoid ticks. But not Tom Mather.
The University of Rhode Island researcher goes out of his way to find them.

There are several exotic snake species that have become a problem in the Everglades. But for wildlife managers, the biggest headache is the Burmese python.
Earlier this year, researchers with the U.S. Geological Survey captured the largest Burmese python yet in Everglades National Park. Three USGS staffers had to wrestle the snake out of a plastic crate to measure it. The snake was a 17-foot-7-inch female carrying 87 eggs.
Wildlife managers are working to get a handle on the problem of exotic snakes in South Florida; but the snakes have already made a big impact.
