...rocket either exploded or caught fire when its fuel tank, containing some 270 tons of kerosene and liquid oxygen, suddenly ignited and turned the launching pad into a flaming ball. In such emergencies, the capsule, its crew snugly strapped inside, blasts away from the pad within milliseconds after the blowup. The rocket tip arcs up to an altitude of several thousand feet, where the capsule then rolls out of its casing (much like a tennis ball out of a tin can) and parachutes safely back to earth...
Whether they prefer glamorous health club or old-fashioned gym, the new Spartans strive for improvement at each workout. This objective, which is achieved by exerting the muscles to their limits, paradoxically expands those limits, improving strength, flexibility and the capacity to use oxygen efficiently. Recent studies advise that regular exercise may help stave off heart attacks and clogged arteries; it is now being suggested as therapy for such noncardiovascular diseases as certain types of diabetes (the body's cells make better use of insulin) and asthma. For some people, heavy exercise like weight training seems to slow down...
Forced into the ground, the water will help push oil to the surface, its low oxygen content ensuring that microorganisms do not grow to inhibit the oil flow. Currently, the wells produce 1.5 million bbl. daily. The STP-processed water will guarantee that an additional 1 billion bbl. can be extracted from the sandstone beneath the Beaufort Sea before production slacks off in the 1990s...
...fame as the world's strongest expedition climber. He talks with the rocklike confidence of all the mountain world's hard men, saying, for instance, that Everest by the traditional Hillary-Tenzing route is "a good holiday, but not really challenging." Messner has never used oxygen in his life, he says with a trace of pride. But he offers freely the opinion that his memory has been dulled by long periods of oxygen deprivation. There have been other prices. His brother Gunther died in an avalanche while climbing with him on Nanga Parbat, in the Himalayas. Messner...
...catheter between the lining of the uterus and the chorion, a layer of tissue that surrounds the embryo during the first two months and later develops into the placenta. The goal is to suction up a sample of the chorionic villi, finger-like projections of tissue that transfer oxygen, nutrients and waste between mother and embryo. "It's like vacuuming a shag rug; you get about half a dozen villi," explains Dr. Laird Jackson of Philadelphia's Jefferson Medical College, which has helped pioneer the technique in the U.S. Since the tiny chorion sample is composed...
