The cliche goes that women spend hours, weeks, years, even entire lifetimes trying to figure out how to land a man. Well, there's one item every lady looking to impress a fellow can cross off her list: Drinking. As drinking becomes the pastime of choice across college campuses, many women have started trying to match their male counterparts drink for drink in an effort to make an impression. An impression she might make, but a new study shows it isn't a good one.

Dartmouth College researchers have created a robot so small that 200 of them could fit on the tip of your finger. The tiny machine crawls like an inchworm across a grid at the breakneck speed of 200 microns per second. Its goal: to fix really little things. Dartmouth engineer Bruce Donald says swarms of such devices could one day repair circuitry in computer chips.
