...unspoken factor that has kept the women's movement from becoming a consistent force in American politics: class. In office after office last week, informal polls often turned up the same split: secretaries sided with Thomas while their male and female bosses took Hill's side. When J.C. Alvarez came forward as a witness for the judge and described Hill as aloof and ambitious, she played a real-life version of Tess, the secretary pitted against a Wall Street shrew in the movie Working Girl.

It was this discovery that led Luis Alvarez to his momentous - insight. Comets and asteroids have high iridium content, he reasoned, and the clay layer could have been formed by the worldwide fallout of the material vaporized when an errant asteroid or, as most scientists now suspect, a giant comet smacked into the earth...
This week, at an astronomy conference in Flagstaff, Ariz., scientists will add an intriguing twist to the Alvarez scenario. Their interpretation is based on new evidence that the Cretaceous-clay boundary actually consists of two parts: a thin layer overlying a more substantial one. To Eugene Shoemaker, of the U.S. Geological Survey and a co-author of the report, two layers indicate not one but two impacts...
...necessary. Shoemaker points to a well-known crater, 35 km (22 miles) across, that lies partly buried near Manson, Iowa. Its age, established by radioactive dating: 65 million years. / Shoemaker believes the new findings will help persuade more scientists to "get off the fence" and side with the Alvarez theory. "Chicxulub is the smoking cannon," he says, "and Manson is the smoking pistol...
