New microchip technology may accelerate drug discovery for cancer, other diseases

Flasks, beakers and hot plates may soon be a thing of the past in chemistry labs. Instead of handling a few experiments on a bench top, scientists may simply pop a microchip into a computer and instantly run thousands of chemical reactions, with results - literally shrinking the lab down to the size of a thumbnail.
