Uncle Sam wants you to email your doctor. A federal law passed in 2009 says that physicians have to start offering their patients online communication, or Medicare will start docking how much it pays them in the future.

Imagine, as he does, turning dozens or hundreds of remote Pacific islands into coconut sanctuaries. Each island would contain just a few varieties of these trees. No others would be allowed, because the whole point of this exercise is to prevent uncontrolled mixing of genes from different varieties.

Scientists working on NASA's six-wheeled rover on Mars have a problem. But it's a good problem.

They have some exciting new results from one of the rover's instruments. On the one hand, they'd like to tell everybody what they found, but on the other, they have to wait because they want to make sure their results are not just some fluke or error in their instrument.
