Long Shot It sounds too good to be true: high-quality flat lenses that focus light and can be made in sheets and cut to size. That's the promise of a new class of materials with a negative refractive index that bend light in the opposite direction from conventional materials. |

Crystal bends light back Being able to bend light backwards is extremely useful. This negative refraction is controversial in physics circles and has only been demonstrated using artificial materials containing metal loops. It turns out that a common natural crystal has harbored this capability all along. |

Light clock promises finer time Researchers have made a prototype atomic clock that divides time on optical radiation, rather than microwave radiation. Such clocks could eventually improve global positioning systems, make space exploration more accurate, and more accurately test the laws of physics. |
