Publicity is the life's-breath of a demagogue. Without it. his inflamatory shenanigans are extinguished like candles without oxygen. We should therefore be wary of the ease with which these provocateurs gain widespread exposure...
...scientists flew into McMurdo Station, Antarctica, to investigate a mystery: What causes a thinning in atmospheric ozone above the frigid continent, a phenomenon that has peaked each October since it was first observed in 1983? It was hardly an academic question; the ozone layer is a blanket of oxygen molecules that protects the earth's surface from the sun's harmful ultraviolet radiation, a form of light just beyond the human range of vision. Speculation on the reason for these "holes" has ranged from weather patterns and solar activity to the action of man-made chlorofluorocarbons (CFCs), chemicals used...
...reason for concern is that without ozone, life on earth would be impossible. Ozone is oxygen but in an unusual form. Most oxygen comes in two- atom molecules, but external energy -- in this case, the sun's ultraviolet radiation -- can split some of them apart. The single oxygen atoms tend to attach themselves to the remaining molecules, forming an oxygen-atom triplet. The result: a layer, from six to 30 miles up, of ozone-enriched air. Once formed, an ozone molecule is a good absorber of ultraviolet. But when CFCs rise to the ozone layer, sunlight decomposes them, releasing...
...chain to Sikkim, exceed this mysterious boundary between life and death. To climbers they are known as the eight-thousanders. And many of them, including Mount Everest, were conquered by mountaineers who fudged a little: they used bottled air. No one had ever conquered all 14 -- much less without oxygen -- until last week, when Reinhold Messner, 42, a brash, blond-bearded native of Italy's South Tirol, stood triumphantly atop Lhotse, the world's fourth highest mountain. Having conquered 13 other eight-thousanders in the past 16 years, all without oxygen, Messner had completed mountaineering's grand slam...
...Gloved One looking like the star of a B-grade sci-fi flick. Jackson got interested in the idea after he was hospitalized for burns two years ago and learned that hyperbaric chambers could speed up the healing of damaged tissue by enabling a patient to breathe oxygen for an hour or two under double the barometric pressure at sea level. "Michael says it is good for his body," Manager Frank DiLeo told USA Today. "I don't think so and neither does his doctor. I can't figure him out sometimes." Strange goings-on indeed...
