The nearby star system Fomalhaut – of special interest for its unusual exoplanet and dusty debris disk – has been discovered to be not just a double star, as astronomers had thought, but one of the widest triple stars known.

Bright, laser-based lighting devices

As a modern culture, we crave artificial white lights - the brighter the better, and ideally using less energy than ever before. To meet the ever-escalating demand for more lighting in more places and to improve the bulbs used in sports stadiums, car headlights and street lamps, scientists are scrambling to create better light-emitting diodes (LEDs) -- solid state lighting devices that are more energy efficient than conventional incandescent or fluorescent light sources.
