Materials Hold Secret to Better LED Performance, Efficiency, Value
There’s little doubt that LEDs save energy, but the high initial cost of LED lamps is preventing mass adoption by lighting consumers. New materials are crucial to driving down the price tag and driving up market acceptance. The price of LEDs has come down rapidly over the past three years, and this trend is expected to continue over the next couple of years until LED lamps reach mass...

Celestial light switch reveals lunar ranging data
When certain members of the universe play a linear game of hide-and-seek, humans pay attention: Many don special solar glasses; others stay up late to catch sight of a burnt-orange moon. Solar and lunar eclipses are sights to behold, appearing just a few times a year and visible only to certain geographies. The power of an eclipse, however, can be harnessed for uses other than wonder: On Dec. 21,...
