...machines offered such innovations as ultradense clusters of circuit boards cooled by liquid nitrogen, but lacked adequate software. Control Data lost about $200 million on supercomputers during the past three years, and Chairman Robert Price thinks the venture would have consumed plenty more. Said he: "Let's put it this way: there are less risky ways to bet $200 million in the computer industry...
...Italian researchers forced deuterium gas to diffuse into scraps of titanium at high pressure and at several different temperatures, ranging from 73 degrees below zero Centigrade--the temperature of liquid nitrogen--to room temperature. All other experiments have used either heavy water or liquid deuterium...
...tiny, fuzzy green ball of light, and its major moon, Triton, as an orange dot. Voyager will provide the first closeup view of both. Triton is especially tantalizing, since it is believed to have its own thin atmosphere of methane, and may be partly covered by oceans of liquid nitrogen...
...Federal Aviation Administration has been working with two U.S. companies to solve the problem. Starting next summer, the FAA will receive five new devices developed by San Diego-based Science Applications International Corp. for screening checked luggage. The machine bombards luggage with neutrons that interact with the nitrogen in explosives, touching off a characteristic pattern of gamma rays. In tests conducted last summer at Los Angeles and San Francisco airports, the devices spotted more than 95% of suitcases containing test samples of explosive materials. But because they employ dangerous radiation, the machines, which cost as much as $1 million each...
...energy, the U.S. produces less than half as much economic output as Japan and West Germany. Meanwhile, the commitment to reduce pollution has flagged. Although the U.S. accounts for less than 5% of the global population, it generates 15% of the world's sulfur dioxide emissions and 25% of nitrogen oxides and carbon dioxide. Each American produces an average of 3 1/2 lbs. of trash...
