...from the emerging technology of cryogenics (application of temperatures close to absolute zero*) and helped to adapt an extremely cold probe to destroy hard-to-reach pituitary tissue in brain operations. Now Rand is making use of another recently utilized phenomenon: superconductivity. With the help of a powerful "superconductive" magnet, he is accomplishing knifeless, bloodless destruction of tumors...
Rand had previously employed magnetism in the operating room. In 1966, he injected microscopic iron spheres into blood vessels of patients who had suffered aneurysms, or "blowouts" in blood vessels in the brain. He used the magnet to hold the filings in place at the site of the rupture until new tissue grew over them to close the hole...
Rand's plan for destroying tumors required an even more powerful magnetic field. To get it, he used an electromagnet cooled by liquid helium to near absolute zero. That produced superconductivity: the virtual disappearance of electrical resistance in the magnet. This allowed a greatly increased flow of current and boosted the strength of the magnet to 3½ times that of the best alternate magnet available...
Richard Nixon is banking that a future coalition of previously contending nations will act like a magnet, and that soon even irascible India will be drawn in for her own good. Nixon understands the world. "It's a street scene to him," Kissinger once said in admiration. "You talk of Saigon or Karachi or almost any place, and he has been there. He can see it and hear it and smell...
...last week's B-26 mission, part of a six-week test being conducted by the National Oceanic and Atmospheric Administration (NOAA), was to prevent the buildup of electrical potential during a storm, and thus to prevent the occurrence of damaging lightning. Like iron filings near a bar magnet, the 4-in.-long, hair-thin fibers, when released in a thunderhead, align themselves with the lines of force in the electrical field of the cloud. What is more, negative and positive charges build up at opposite ends of the fibers, creating miniature electrical fields and ionizing the air around...
