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.

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.
He looks for deer ticks — poppy seed-sized skin burrowers — in the woods of southern Rhode Island. These are the teeny-tiny carriers of Lyme disease, an illness that can lead to symptoms ranging from nasty rashes to memory loss.

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.

STEVE INSKEEP, HOST:
Just over a couple of decades ago, there were fewer than 100 otters remaining in the state of Illinois. Today, there are at least 15,000. They're furry and cute and a nuisance to some, often called the raccoons of Illinois waterways. What's wrong with raccoons? Anyway. So for the first time in almost 90 years, Illinois has reinstated otter trapping season. We called Bob Bluett, a biologist with the Illinois Department of Natural Resources.
