Next year Great Wall plans to launch its first commercial payload, a Westar 6-S communications satellite for New York-based Terasat. It will transmit television programming and business data for Western Union and other users. The Chinese have also signed an agreement to launch a Swedish satellite, and are holding talks with 17 other nations. For customers who are concerned that China may copy the technology in satellites, Great Wall suggests that they package the payload in a sealed container and send along representatives to escort the cargo to the launch site...
...test means that an individual has been exposed to the AIDS virus and has developed antibodies to it, not necessarily that a person has -- or will fall victim to -- the disease. Scientists assume, but have not proved, that those who test positive are still carrying the virus and can transmit it. Moreover, additional testing is needed to confirm a positive result. Negative results can also be deceiving. Since the virus apparently takes from six to twelve weeks to provoke antibody production, an individual may have been exposed and still not show antibodies...
Suddenly, at 93 Kelvin (-292 degrees F), the resistance dropped precipitously. The substance had become a superconductor, able to transmit current with virtually no loss of energy. "We were so excited and so nervous that our hands were shaking," says Physicist Maw-kuen Wu. "At first we were suspicious that it was an error...
...Science Foundation announced last week that Chu's Houston lab had pushed that temperature 5 degrees higher -- to 98 K. Under such conditions -- far less extreme than those required only a few years ago -- superconducting technology might eventually become inexpensive and even commonplace. Possible applications: superconducting cables that could transmit electricity from a power plant to a distant city with essentially no energy loss; practical versions of trains that "fly" ) just above their tracks at hundreds of miles an hour, cushioned on magnetic fields; more widespread use of magnetic resonance imaging machines, which take sharp pictures of the soft tissues...
...adept at fund raising and politicking as they are at probing the subatomic world. Author Gary Taubes provides that view while chronicling the research that won Italian Physicist Carlo Rubbia a share of the 1984 Nobel Prize in Physics for discovering the W and Z particles, which transmit the so- called weak nuclear force...
