...University of Alabama in Huntsville, physicists last month placed a chip of a green, brittle compound inside a thermos-like container, doused it with frigid liquid nitrogen and sent an electric current through it. As the temperature dropped, they took careful measurements of the compound's electrical resistance -- its opposition to the passage of current...
...most uses, however, the cost of liquid helium outweighs the benefits of superconducting technology. For that reason, scientists have long searched for a compound that would become a superconductor at less extreme temperatures -- particularly above 77 K (-320 degrees F), the point at which nitrogen gas liquefies. Reason: nitrogen is a common gas and costs no more than a tenth as much in liquid form as helium. In fact, says Iowa State University Physicist Douglas Finnemore, liquid nitrogen, priced as low as a nickel a liter, is a "heck of a lot cheaper than beer...
...much sought-after goal proved to be elusive. In the early 1970s scientists found an alloy of niobium and germanium that lost all resistance at 23 K. Then, last April, a group at the IBM Zurich Research Laboratory in Switzerland announced development of a compound of barium, lanthanum, copper and oxygen that appeared to begin the transition to superconductivity...
Most of the rebellion's drama centered on the Channel 7 TV compound in suburban Manila, where some 160 mutinous soldiers and 100 civilians huddled inside the walls while a thousand government troops waited nervously outside. Since friendships cut across the lines, the two sides opted to trade radio messages instead of shots. "Mommy, take care of my children," sobbed a female mutineer. Came the government's response, from the five-year-old daughter of Rebel Leader Colonel Oscar Canlas: "Daddy, come home. Mommy has a stomachache...
...Oueddei, who was once the country's President and has more recently been the leader of the northern rebels, and Hissene Habre, once a guerrilla leader and since 1982 the President. Three months ago, while ( visiting the Libyan capital of Tripoli, Goukouni was shot and wounded in the Gaddafi compound under circumstances that have never been explained. He is still in Libya, reportedly under house arrest...
