Meanwhile, clinical and molecular researchers are launching a biological attack on the virus. Their objective: the development of vaccines to prevent its spread and drugs to treat those already infected. But the AIDS virus is a formidable adversary. Because it can reproduce so rapidly, says Harvard's Haseltine, it can mutate frequently, changing its outer coat (the essential ingredient in making a vaccine) 100 to 1,000 times as fast as quick-changing flu viruses. As a result, he says, "trying to develop a vaccine for AIDS is like trying to hit a rapidly moving target." Scientists are now searching...
Many impostors develop these fears after early successes. When Eleanor, a nuclear engineer cited by Clance, became one of the first women to obtain a top position in her field, she refused to accept her accomplishments. "I'm not very bright at all," she says. "I don't really belong here...
Many of these experimental weapons, of course, may never find their way into the American arsenal. Some may prove impractical, while others may fail to win congressional funding. Only a fraction of past DARPA projects have been deployed. But the 27-year-old agency, which helped develop the cruise missile and the Stealth bomber, has had a powerful impact on strategic thinking. Among the sophisticated systems now under...

...common, in fact, that Reagan was not the only American leader reported last week to be afflicted with it. Former President Richard Nixon, it was revealed, underwent treatment two weeks ago to excise a basal-cell growth behind his left ear. In all, approximately 500,000 Americans a year develop skin cancer, and the overwhelming majority of these are basal-cell carcinomas, usually small, pearly nodules that sometimes become red, crusty lesions and appear most often on the face. "The sun is responsible for almost all of them," says Dr. Perry Robins, a New York University dermatologist and president...
