Nanotechnology cuts water use, energy costs

As part of a larger consortium involving partners from several energy companies, universities, and government agencies, researchers at the U.S. Department of Energy's Argonne National Laboratory are developing a special class of nanoparticles that partially melt as steam evaporates from a plant's cooling towers, absorbing a significant percentage of the diffused heat in the system.

New frontier: Chips transfer data at light speed

The computer industry is nearing a crisis: microchips get smaller and faster but they struggle to transfer data at sufficient speeds. Electrons flowing through standard chip connections are just too slow. Now EU-funded researchers have shown how chips with built-in lasers which use multiple wavelengths of light could in the future transmit data at terabit speeds.
