MOMA Online has an exhibit entitled Design and the Elastic Mind which is a bunch of different projects combining art and science. The Bee's Project is one of these. Basically it consists of a number of glass vessels with bees inside. Taking advantage of a bee's highly sophisticated sense of smell, they are trained to detect different diseases, from cancer to pregnancy (which, in my wife's case, IS a disease). If the bees sense a certain odor when a user blows into the device they will fly into a corresponding chamber, indicating the presence of whatever disease they've been trained to detect. Or if you have shit-breath then the bees all congregate in the bottom. You know, because you killed them all.
A couple more pictures and a link to the exhibit after the jump.
