Scientists in Australia have applied a ghostly phenomenon called quantum entanglement to dismantle a signal - transmitted in photons, or particles of light - in one shaft of laser light and instantaneously rebuild a replica of it in a second laser beam.
Researchers at the Pacific Northwest National Laboratory have developed a lightweight space age generator that can generate 25 watts and keep going for a week. The generator will enable future soldiers and police officers to carry laser weapons and sophisticated computer, navigation, and imaging equipment.
A new eye in the sky is about to take the measure of a pollution problem that is out of this world. A US satellite to be launched today will count bits of cosmic debris 500 miles above the Earth's surface.
