Like most comets, I-A-A contains molecules of ammonia and nitrogen, along with water, presumed building blocks of the solar system. But another satellite, the International Ultraviolet Explorer, also found surprising indications of sulfur molecules. Said University of Maryland Astronomer Michael A'Hearn: "The sulfur may be one of the few things we see that actually reside in the comet's nucleus." The most stunning observational feat came when the big, 1,000-ft. radio telescope in Arecibo, PR., managed to bounce radar waves off the fleeting object and perhaps settled the old argument over whether cometary...
ACCORDING TO MOST REPORTS, the two films dealing with acid rain--"Acid From Heaven" and "Acid Rain: Requiem or Recovery"--present a low-key, moderate account of one of the most highly injurious forms of air pollution. Acid rain, which results from sulfur dioxide emissions from coal and some power plants, poses a tremendous threat to the environment. Produced mainly in the Eastern U.S., it acidifies lakes and streams, killing fish and other aquatic wildlife, and has been found to cause excessive root decay to forests and crops and to corrode man-made structures. The human dangers of acid rain...
...large swatches of the earth in a multiplicity of colors, some of them beyond the range of human vision. Returning to the same site every 16 days, it can sound the alarm to changes in the health of crops, spot flows of pollutants into bodies of water, or track sulfur-laden clouds from fuming volcanoes...
...penalty unless it was preceded by terror, torture and humiliation, preferably in public. One of history's most spectacular executions was that of Damiens, the unsuccessful assassin of Louis XV, in Paris in 1757. His flesh was torn with red-hot pincers, his right hand was burned with sulfur, his wounds were drenched with molten lead, his body was drawn and quartered by four horses, his parts were set afire and his ashes scattered to the winds. The execution was accomplished before a large crowd...
Most utilities are vociferously opposed to any emission-control program without further research into the causes of acid rain. The industry argues that 1) scientific data on acid rain are still fuzzy, especially in the crucial matter of precisely who is responsible; 2) costs of eliminating sulfur-dioxide emissions by installing expensive "scrubbers" (which collect harmful substances before they are expelled) are prohibitive; and 3) it is questionable whether the situation is critical enough to justify immediate action. Says Joseph Dowd, general counsel for American Electric Power, which serves 2.5 million customers in the Midwest: "Installing scrubbers could break...
