Plants have been using a green pigment for billions of years to capture sunlight, turning it into a flow of electrons and storing its energy in the chemical bonds of big organic molecules (also known as food). Given that successful history, chemist Michael Graetzel of the Swiss Federal Institute of Technology in Lausanne and his colleagues turned to a compound similar in shape and color to chlorophyll when they set out to build a better solar cell.

New experiments find that cell phone signals don't just confuse bees, they off them.

Scientists at CalTech are perfecting a technique that converts water, air, and sunlight into different kinds of fuel that could power everything from car engines to fuel cells in cell phones. It sounds almost too good to be true, from an environmental stand-point.

Neuromarketing goes mobile with this lightweight, dry, and iPhone- or iPad-compatible new device from NeuroFocus.
