| HIDING IN THE NOISE AND CHAOS |
| A new and novel way of communicating over fiber optics is being developed by physicists supported by the Office of Naval Research. Rather than using the amplitude and frequency of electromagnetic waves, they're using the polarization of the wave to carry the signal. Such a method offers a novel and elegant method of secure communication over fiber optic lines. |

| LASER-LIKE BEAM MAY BREAK BARRIERS TO TECHNOLOGICAL PROGRESS |
| Researchers have created a sharply focused, laser-like beam of ultraviolet light using a device that could fit on a dining room table. Scientists and engineers will be able to use this extreme ultraviolet (EUV) light source to measure and manipulate objects at the scale of nanometers (billionths of a meter). |

| LIGHT COULD REPAIR EYE INJURIES |
| HOW do you treat people blinded by light? With more light. Shining near-infrared radiation on damaged retinal cells can keep them alive and prevent permanent blindness.
The US Defense Advance Research Projects Agency is funding research into the method and hopes to use it to treat people whose eyes are damaged by lasers. A number of US military personnel, including a helicopter pilot over Bosnia in 1998, have suffered laser eye injuries. |
