Kids get cavities. Dentists fill them. It's a fairly old arrangement, but it may soon come to an end if cavities go the way of smallpox. Jeffrey Hillman's company, Oragenics, has patented a simple swab of bacteria that when wiped across a set of teeth will (allegedly) grant a lifetime of protection from tooth decay. By this fall, Hillman, a dental researcher at the University of Florida, will begin testing the new strain on 15 to 30 volunteers.
The Vision: "Print media doesn´t have to be static," says Syracuse University´s Ryan Bednar, who with fellow student Nate Schaal designed a device that can "print" a multilayer electronic display-think 20 pages on a single sheet, with a Web-like interface. Key tech: Ink is embedded in layers of resin-apply a current and the desired page appears.
