Two new joint degree programs, one designed to strengthen the science and technology backround of science writers, and a second to train students in designing computer-based educational materials
It's a tale of Down Under, set against a backdrop of international terrorism. On a dark night in May, 1993, somewhere in the empty miles of dry-as-dust Australian outback, a streak blazed through the sky and the ground shook, according to eyewitnesses, aborigines prospecting for gold.
In a major technological breakthrough, Bell Labs researchers have demonstrated continuously tunable, single-mode, high-power room-temperature QC distributed-feedback lasers operating at mid-infrared wavelengths (5 and 8.5 micron) in pulsed mode. The single-mode tuning range is typically 50 nanometers in wavelength, and the peak powers are 60 milliwatts, one and two orders of magnitude better, respectively, than commercially available mid-infrared lead-salt lasers.
In a major breakthrough, Bell Labs scientists have demonstrated the world's first laser-based semiconductor sensor that operates at room temperature and at high power to detect minute amounts -- potentially parts per billion -- of trace gases or pollutants by scanning for their optical-absorption "fingerprints."

Beta-carotene supplements can sharply reduce the risk of prostate cancer in men with low beta-carotene blood levels, according to new findings released by researchers at the Harvard Medical School. An earlier study by Harvard researchers showed that men consuming large quantities of tomatoes rich in lycopene, had only about half the risk of prostate cancer as did men who consumed little of the nutrient. Prostate cancer is the second leading cause of death from cancer in men.
