...line Bible and the Sibyllenbuch fragment, the Davis team exposed them, one at a time, to the proton beam. The results of those tests, begun in 1982, are still being evaluated, but most of the doubts about Gutenberg's role have vanished. The Davis tests established that instead of carbon-based ink, the German printer employed a slurry of copper and lead for his famous Bible. Printed characters in both of the 36-line works, the X-ray patterns showed, consisted of an almost identical mixture. The conclusion: Gutenberg printed all the works, and the 36-liners were his earlier...
...time of Columbus. In 1974, however, some particles of ink from the map were found to be titanium-based. This meant, experts said, that the ink was of 20th century vintage and the map a fraud. But the Davis team, using their cyclotron technique, proved the ink was carbon based, with titanium present only in trace amounts. Says Cahill: "We feel that the question of the map's authenticity is once again open...
...Omaha deaths raise an obvious question: Is suicide contagious? Recent clusters of adolescent suicides suggest that the answer is yes. In a twelve- month period beginning in February 1983, seven teenagers in Plano, Texas, committed suicide, four by carbon-monoxide poisoning, three by guns. Five boys in New York's Westchester and Putnam counties died by their own hand in February 1984, four of them by hanging. Within the past two weeks, one student at David Prouty High School in Spencer, Mass., committed suicide; at least two schoolmates, possibly four, tried to kill themselves and failed...
Hollywood must make movies that speak to the present, not concepts or carbon copies but reverberant stories and demanding images. Says Robert Benton, whose Kramer vs. Kramer was the top-grossing film of 1979: "The most interesting development of the past year was the success of the old-fashioned thriller: Witness, Prizzi's Honor, Jagged Edge. They didn't have a teenager among them. Maybe studios will begin to rethink their policies." Kaufman dares to predict "a return to movies about relationships. The mood has changed; the divorce rate is dropping. I see 40-year-old couples standing in movie...
...expanded. By studying the spectra of light emitted from molecules broken down in the gaseous coma, scientists have estimated that a comet's nucleus consists of two-thirds water, one-fifth dust (particles averaging one-thousandth the width of a pinhead) and the rest a mixture of methane, ammonia, carbon dioxide and trace elements...
