...composer Philip Glass, 57, has been inviting comparison with Wagner ever since the 1976 debut of his four-hour epic Einstein on the Beach, Wagnerian in length and scope if not in idiom; and the Wagnerian ideal has been evident in much of his later work as well -- in Hydrogen Jukebox's marriage of Minimalism to the poetry of Allen Ginsberg (1990), and in 1,000 Airplanes on the Roof (1988), which combined David Henry Hwang's text and Jerome Sirlin's images...
...fundamental tenet of atmospheric chemistry is that ozone depletion is controlled by nitrogen oxide radicals and the hydrogen oxide and halogen radicals play a much smaller part," Anderson says. "We have experimentally shown that in the lower ozone layer, the hydrogen oxide radicals are on top and the halogen radicals are dominant. The nitrogen oxide radicals play the smallest role at less than 20 percent...
...Most of the nitrogen and hydrogen radicals are produced by natural activities," says Salawitch. "But the halogen radicals, primarily bromine and chlorine, are primarily due to industrial activity...
Fatty acids, the building blocks for fat, are divided into three chemical classes according to their hydrogen content: saturated, mono-unsaturated and polyunsaturated. Only the polyunsaturated ones are considered "essential," meaning they cannot be manufactured by the body. Like minerals and vitamins, they must be ingested as food. "If we don't eat enough," says Siguel, "then we won't have enough." And that would be unfortunate, for these compounds -- principally linoleic acid and linolenic acid -- are vital to the maintenance of cell membranes and to the manufacture of potent chemical messengers that regulate everything from blood pressure...
...active Mount Spurr volcano that included a 3-D survey of the hellish terrain and an analysis of gases issuing from belching vents. Among the significant results: the first maps of the crater's surface, normally hidden by outcroppings and haze. Dante also discovered scant sulfur dioxide and hydrogen sulfide in the noxious air, implying that the volcano, which erupted in 1992, will probably stay quiet for a while...
