Raising the Fundamental Power Conversion Limit of Solar Cells

A team of Los Alamos researchers led by Victor Klimov has shown that carrier multiplication-when a photon creates multiple electrons-is a real phenomenon in tiny semiconductor crystals and not a false observation born of extraneous effects that mimic carrier multiplication. The research, explained in a recent issue of Accounts of Chemical Research, shows the possibility of solar cells that create more than one unit of energy per photon.

More Light While Consuming Less

More light while consuming less - the new star in industrial lighting is the LUMILUX T5. No wonder global businesses such as logistics provider DHL rely on these cost-effective fluorescent lamps. They light up DHL's new aviation hub at Leipzig/Halle, for example. The result is low energy costs while maintaining the best lighting conditions in offices, the distribution centre and outside areas.

Vigorous Exercise May Help Prevent Both Cataracts and Age-Related Macular Degeneration

There's another reason to dust off those running shoes. Vigorous exercise may help prevent vision loss, according to a pair of studies from the U.S. Department of Energy's Lawrence Berkeley National Laboratory. The studies tracked approximately 31,000 runners for more than seven years, and found that running reduced the risk of both cataracts and age-related macular degeneration.
