...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...
...degrees F) and discovered that it had lost its resistance to electric current. Since then more than two dozen chemical elements and hundreds of compounds have been found to be superconductors near that temperature extreme. The only practical way to make something that cold is to bathe it in liquid helium, which exists only at temperatures below 4 K. But helium is rare, and expensive to liquefy. Even so, the efficiency of electromagnets wound with superconducting wires is so great that in certain situations the expense is justified...
...example, giant particle accelerators require extremely powerful magnets to keep the particles confined to a circular track as they move at nearly the speed of light. At Fermilab, near Chicago, the world's most powerful accelerator, known as Tevatron, uses more than 1,000 superconducting magnets cooled with liquid helium at a cost of $5 million a year. But the efficiency of the magnets saves Fermilab an estimated $185 million annually in electric energy costs. The superconducting super collider, a mammoth accelerator 52 miles in circumference, endorsed last month by President Reagan for completion in the 1990s at a projected...
...naturalists want Governor Michael Dukakis to put a halt to the renovation and declare the park a sanctuary, with only guided tours permitted. That would restore the pristine conditions Thoreau loved -- but would reduce the number who could share his fascination with a spot that, in his words, radiated "liquid joy and happiness...
...gunmen who were actually aboard TWA Flight 847 when it was commandeered and who savagely beat and then shot the American sailor. Hamadei was detained at Frankfurt's international airport after officials discovered he was carrying a false passport and bottles packed with liquid explosives...
