A second day of violence in Vietnam has seen mobs singling out Chinese workers for attack, killing at least one and injuring dozens, as hundreds of Chinese nationals fled the country by land and air. A major foreign-owned steel operation was set ablaze in the country's north.

Many potential new drugs look like they could be big winners — at least when judged by how well they work in mice or other lab animals. Over the years, there have been a number of promising cancer "cures," possible Alzheimer's treatments, and candidate drugs for holding back the ravages of various degenerative diseases.

Octopus arms keep from getting all tangled up in part because some kind of chemical in octopus skin prevents the tentacles' suckers from grabbing on.
That was the surprise discovery of scientists who were trying to understand how octopuses manage to move all their weird appendages without getting tied in knots.
