Situation: The enemy commands a steeply rising stretch of rocky hills some 40 miles long, providing clear fields of fire on the plains below. Three separate lines of defense run along the hillsides, one above the other. Each line has its own triple layer of mines, barbed wire and heavy fortifications, for a total of nine miniature Maginot Lines that must be breached to reach the final plateau...
Under that layer is the work of an attractively gifted singer, her husky, throbbing contralto giving off a languor that occasionally approaches drowsiness, her guitar unexceptional but sufficient. Though a newcomer to solo circles, Bobbie is clearly a pro. Her first song, composed at the age of seven, was picked out on the family's upright piano, and had to do with her English shepherd, Sergeant. Later came studies at the Los Angeles Conservatory and U.C.L.A., but not for long. Since the age of 17, Bobbie has supported herself in assorted musical jobs, working...
...layers of the skin involved in the sun-screening process are visible under a microscope. Below the skin's outermost horny layer, or stratum corneum (see diagram), lies a germinative layer where, on exposure to sunlight, the pigment-producing cells are stimulated to produce more melanin-and a suntan. The black races (Negro, Bushman-Hottentot and Australoid), with a more abundant supply of melanin, are in effect, perpetually tanned. Members of the white race are transparent-skinned in winter, when they must make the most of the limited ultraviolet avail able to synthesize vitamin D, but they take...
...helicopter pilots, he is also developing a 23-lb. vest (too heavy for infantrymen) with 14 layers; the eighth layer has stopped submachine gun slugs fired from 15 yds. In Viet Nam, helicopters are armored with titanium that stops snipers' .30-cal. bullets at 200 yds. But "any closer," says Davis, "and the bullets go right through." He proposes lining helicopters with 14-layer nylon, which can increase the amount of protection by 40% while reducing the cost of the armor by about the same amount...
...Davis-Weinberger fabric will soon be tested in Viet Nam as a boot lining to protect infantrymen against poisoned bamboo stakes set out by the V.C. At a recent Davis demonstration, a single layer of the nylon draped over a man's knee stopped a chain saw cold, indicating a wide range of possible industrial uses. Samples have since been ordered for evaluation by the Air Force, the Marines and five foreign nations. Police in several U.S. cities are also interested. During the riots, a New York City patrolman was slashed open from shoulder to waist by a looter...
