Gel Bots? Vibrated goo mimics slithery motions
The ability of soft, jellylike hydrogels to move as do snails, snakes, and inchworms may point the way to a new class of squishy robots that promise to be simple, quiet, and versatile.

Wash Those Hands!
A Florida-based company is now developing a laser-based scanning technology to scout for dirty hands. Installed in restaurant washrooms or daycare centers, it could identify fecal traces — evidence that hand washing was incomplete. Indeed, these sensors might even be coupled to a lock that allows workers back into a kitchen after a restroom break, notes Richard Stroman, vice president of eMerge Interactive, which is applying for a patent on the system. Kitchen or food-processing-plant workers who don't pass the laser test would be forced to go back and lather up again.
