Newspaper office computers are frequent targets for prying. One reason: news organizations make extensive use of open telephone lines to transmit and receive electronic messages. In addition, notes Geoffrey Stokes, press columnist for New York City's Village Voice, "We are all professional snoops." Stokes' columns frequently contain items leaked to him from the computers of the large New York dailies. Last year he gleefully printed a memo purloined from the New York Times revealing that Arthur Gelb, one of that paper's top editors, asked a Paris reporter to investigate the effects of the Chernobyl nuclear accident on Russian...
...chief advantage of ISDN, especially for businesses, is that it enables phone users to transmit voices, video images and computer data along the same line simultaneously. In analog systems, separate lines are required for each of these functions. But with ISDN, callers can easily exchange documents, see each other and talk all at the same time. Moreover, ISDN will enable otherwise incompatible computer systems to communicate with one another. And greater amounts of data can be transmitted much more rapidly through ISDN than with analog equipment...
...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...
