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...
...nature is often, necessarily, more than somewhat bizarre. Thus we see the attempt by Mountaineer Tabin's group to climb Everest by an approach once thought foolhardy, and the astonishing accomplishment of Italian Superclimber Reinhold Messner three years ago of reaching Everest's summit alone and without oxygen...
...fragile as moths, and transatlantic crossings are made in sailboats only marginally longer than their pilots. There are specialists in climbing frozen waterfalls and skiing slopes too steep to stand on, and in exploring underwater, with scuba gear, caves so deep that helium must be mixed with the oxygen that is breathed, to forestall nitrogen narcosis. A couple of canoeists have just lined their craft up the Grand Canyon and portaged the Rockies. An unemployed actress named Julie Ridge swam twice around Manhattan Island this summer (about 28 miles); although the publicity did not bring her a job, she said...
...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...
