A Stanford mechanical engineer is using the biology of a gecko's sticky foot to create a robot that climbs.

ALBUQUERQUE, N.M.— Solid-state lighting pioneers long have held that replacing the inefficient Edison light bulb with more efficient solid-state light-emitting devices (LEDs) would lower electrical usage worldwide, not only "greenly" decreasing the need for new power plants but even permitting some to be decommissioned.

A new approach to building an "artificial nose" – using fluorescent compounds and DNA – could accelerate the use of sniffing sensors into the realm of mass production and widespread use, say Stanford chemists.

Faced with rising electricity and heating costs, more and more consumers are opting to save energy, and now the government is beginning to help them. As from 2011, energy suppliers will be required to offer electricity at variable rates under the German Energy Act (EnWG § 40,3).
