Promising New Material Could Improve Gas Mileage
10 10 2008 With gasoline at high prices, it's disheartening to know that up to three-quarters of the potential energy you are paying for is wasted. Now researchers have identified a promising new material that could transform a technology that currently cools and heats car seats -- thermoelectrics -- into one that also efficiently converts waste heat into electricity to help power the car and improve gas mileage.

New Material Could Act As Nanofridge For Microchips In Smaller And Faster Computers
09 10 2008 Researchers in Spain have developed a material which could act as a nanofridge for computers, thus eliminating the barrier posed by overheating in ever smaller chips. The material is based on germanium nanostructures, presents a significant reduction in thermal conductivity and therefore could be a potential candidate in the development of thermoelectric systems compatible with silicon.

Highest Power Tabletop Laser Ever Built
09 10 2008 Physicists at the University of Texas have built a tabletop laser that produces, at the present time, the largest peak power of any laser in the world: 1.1 petawatts (PW), or 1,100 terawatts (1.1 x 10^15 watts).
