Super Sunglasses

Researchers have developed a material that almost instantaneously changes from clear to dark blue when exposed to ultraviolet (UV) light, and it just as quickly reverts to clear when the light is turned off. The new material, one of a class called photochromics, could be useful in optical data storage as well as in super-fancy sunglasses.

Composite Plastic-Metal Conductor

Researchers at the Fraunhofer Institute for Manufacturing Technology and Applied Materials Research in Bremen, Germany have successfully created a plastic and metal composite conductive material. Cheaper and lighter than traditional metal conductors, this new material could significantly reduce the cost of printed circuit boards as well as decrease their size and weight with particular applications in the automobile and aircraft manufacturing industries.
