How do cats drink? Is the "wet dog shake" an effective drying mechanism? These may have fleetingly crossed your mind, but it took an engineer to get to the bottom of such creature curiosities.

The ability of felines to lap up an entire bowl of liquid may seem to defy gravity. But four engineers at MIT, Virginia Polytechnic Institute, and Princeton have proven that it's not so. Meanwhile, another team at Georgia Tech is busy analyzing the efficiency of the "wet dog shake."

This brings a whole new meaning to "freeze frame": a team of engineers in Finland has created the world's first ice touchscreen.
