...past times, the area teemed with thousands of breeding gulls. Wheeling overhead, they scavenged for dead fish and refuse-and picked the beaches clean. In 1962, William C. Scharf, a biologist at Northwestern Michigan College, counted 2,500 gulls' nests on nearby Bellows Island alone. This spring he found only 300. Why? Scharf partly blames dune-buggy drivers who careen through nesting grounds, plus harmful human discards like pop-top beer-can rings, which can injure hungry gulls. But the chief reason is heavy use of chlorinated hydrocarbons: DDT and its chemical cousins, dieldrin and chlordane...
Matthew Meselson, Sc.D., molecular biologist, Harvard professor and opponent of biological warfare. As a founder of modern genetics and social conscience for those who advance scientific knowledge, you have demonstrated the power of sustained effort to assure that the science of life does not cause death or destruction anywhere on the globe...
...soil, and at other times when the grasshopper is vulnerable to attack by ants, it noisily emits from openings in its thorax a foul-smelling, brownish froth that halts predator ants in their tracks. To find out why the liquid is so effective, the scientists, led by Biologist Thomas Eisner, extracted it from several hundred grasshoppers and analyzed its contents. In addition to quinones, phenols, terpenes and other chemicals that are often used in insect warfare, they found an unexpected ingredient: 2,5-dichlorophenol, a derivative of a man-made herbicide...

MULTILEVEL PLATFORMS. Architect Michael Black was called in by Harold Slavkin, a Los Angeles molecular biologist, to plan a vacation house. He disposed of all furniture, building a complex of multilevel platforms covered with carpeting. Now guests sit, lie or sprawl, and flop from one tier to another as conversations catch their interest. "In a 10-ft. by 12-ft. area," says Slavkin's wife Kay, "we've had as many as twelve people in practically as many postures." Black also revamped the Slavkins' staid, traditional Los Angeles house. "The problem," he says, "was a cold, formal...
