Lunar Bombardment. Writing in Nature, Physicist Kuan-Han Sun suggests that a combination of the solar wind, meteorites, and lunar temperature changes provide ideal conditions for thermoluminescence-the release of stored-up energy in the form of visible light during a rapid temperature rise. Like other bodies in the solar system, Sun points out, the moon is constantly bombarded by a solar wind consisting of charged, low-energy particles boiled off the solar surface and "blown" into space. Because these particles, which are mostly protons, follow magnetic lines of force, they can strike the moon from all directions, hitting...
...bombarded them with high-energy electrons that simulated the impact of solar-wind protons for a 14-day period. No glow was produced. When Sun removed the liquid nitrogen and rapidly heated the samples, however, they began to give off vivid and pulsating light. The Westinghouse physicist is now working on further laboratory tests to support his theory. He believes that it can also be confirmed by careful telescopic analysis of light emanating from the vicinity of the lunar terminator. If, as he suggests, that band of moonlight is noticeably brighter than the rest of the moon's daytime...
...commission's prescription: a new medical specialty composed of "primary physicians"-so called because they would have first and continuing contact with the patient. Their training, said Dr. Millis, who is a physicist, not a physician, would involve abolition of the present system that calls for medical graduates to serve an internship of a year or more before going into practice. Future primary physicians, like candidates for all other medical specialties, would have to go into a three-year residency program immediately after graduation...
...least gone a long way toward pin pointing his presence. They have built detectors that spot guerrillas by their slightest sounds or movements. They can literally sniff an enemy's presence by the very odors of his body, food or clothing. "What we are trying here," says Physicist R. D. Holbrook, who heads the U.S. contingent at MRDC, "is noth ing less than a systematic approach to the entire counterinsurgency problem. There's time to do in Thailand what we could have done elsewhere - including Viet Nam - if only we had started soon enough...
...retrieve ancient ice, Army engi neers, led by Physicist B. Lyle Hansen, used a thermal drill with a hollow, elec trically heated head that melted its way down through the sheet, while leaving a 51-in. ice core intact inside it. Every 5 ft. the drill was stopped so that the core could be returned to the surface for study...
