Hewlett Packard technicians work on nanotechnology research in a clean room at HP headquarters in Palo Alto, Calif., Tuesday, Jan. 16, 2007. HP researchers say they have developed a way to integrate nanotechnology and traditional circuitry designs in a specific kind of programmable computer chip, an advance that could help companies dramatically reduce the amount of energy their chips use to process information while continuing to manufacture ever-smaller devices.
