The theory - that the dinosaurs died out about 65 million years ago because of global darkness caused by atmospheric dust - has been questioned partly because of the large number of diatoms, a photosynthetic plankton, that survived. According to University geology Prof. Jennifer Kitchell, however, diatoms possess the ability to survive long periods without light or nutrients that could mean extinction for other forms of life. In a paper on mollusks delivered at the Fourth North American Paleontological Convention last August, Kitchell noted that a seasonal survival mechanism in diatoms could be useful in a catastrophic event such as global darkness. D I A T O M S have three life stages, depending on the availability of light and nutrients: vegetative, resting and reproductive. In a seasonal process, diatoms enter a resting stage when there is too much light and too few nutrients, which causes them to sink to the ocean floor until conditions return to normal. A complex process called up-welling, which brings nutrients up from the ocean floor, determines the availability of nutrients for diatoms, and global darkness would affect this process. The decreased availability of nutrients would cause the diatoms to enter the resting stage, said Kitchell. The uneven extinction rate of photosynthetic plankton evident in core samples from that era has been one objection to theories of global darkness. Studies say that on average, only 17 percent of most planktons survived, but the survival rate for diatoms was 77 percent. Scientists have claimed global darkness would have caused these extinction rates to be more equal. Kitchell's discovery provides an explanation for the discrepancy. GLOBAL darkness would have occured if a comet or meteor had struck the earth, according to a theory on the extinction of dinosaurs put forward by Walter Alvarez at the University of California at Berkeley in 1980. In his theory Alvarez suggested that a comet or meteor hit the earth, raising a large cloud of dust that blocked the sun's rays. During this period of darkness photosynthetic plants died, causing extinction all the way up the food chain. Another global darkness theory is that volcanoes spewed ash into the atmosphere. However, according to Philip Gingerich, a University professor of biological and geological sciences, some scientists think dinosaurs began dying out gradually before a S period of global darkness.

Compiled from Associated Press reports UAW ends strike against GM DETROIT - United Auto Workers members at three General Motors Corp. plants yesterday overwhelmingly ratified a tentative local agreement, ending a four-day strike that halted truck and bus production, a UAW spokesman said. Members of Local 594 in Pontiac approved the agreement by a vote of 1,314-25 said Bob Schroeder, the local's education director. "I don't think there was really much doubt about it," Schroeder said. The settlement covered about 9,000 UAW members with GM's Truck & Bus Group in Pontiac. Production of GM's new full-sized pickups and popular sport utility vehicles would resume today, GM said in a written release. "We got everything we wanted on the strike issues and most ev - erything we wanted on the other issues," Schroeder said. Frank Cronin, a GM Truck & Bus Group spokesman said he did not know how much production was lost during the strike. Aquino backs 'people power' DAVAO CITY, Philippines - President Corazon Aquino endorsed unarmed anti-communist citizens groups yesterday as a legitimate example of "people power" and blamed leftist and rightist extremists for national instability. The role of such groups has stirred national debate. Supporters be - lieve the groups can contribute to combating communism. Critics fear they will become a threat to law and order. The military meanwhile remained on full alert against rebel attacks as the Communist New People's Army commemorated the 18th an - niversary of its founding. The military said the rebels threatened to kill a general to mark the date, but there were no reports of attacks. Aquino told about 30,000 people in Zamboanga City that "I blame the leftists and the rightists for the present problems in the country." Greece-Turkey standoff ends ATHENS, Greece - Greeks rallied around the government yesterday and labor unions canceled strikes as a standoff with Turkey over Aegean Sea oil rights ended in what Greece saw as a victory for Prime Minister Andreas Papandreou. A 48-hour military alert was wound down yesterday, but officers could not leave their units, said military sources, speaking on condition of anonymity. Greece planned a show of military strength with a five-day, air-sea, exercise starting today in the northeastern Aegean, where a Turkish re - search ship had planned oil exploration in a continental shelf area claim ed by Greece. Turkey stepped back from a military confrontation with fellow NATO member Greece over mineral rights in the Aegean when it changed the ship's course at the last minute Friday. Protesters decry contra aid DETROIT - An estimated 6,000 people marched peaceably yesterday to protest U.S. intervention in Central America, Detroit po - lice said. No arrests or clashes were reported during the downtown rally de - spite the presence of a few counter-demonstrators, said Sgt. Christopher Buck, a police spokesman. The crowd gathered at the McNamara Federal Building under cloudy skies and marched several blocks to a plaza. Speakers, including actor Edward Asner, criticized Reagan Administration policies in Central A - merica, including support for the Contra rebels seeking to overthrow, the government of Nicaragua. EXTRAS Money machine mixup profits perplexed patrons Students who went to withdraw money from the money machine at the corner of South University and East University over the weekend received quite a shock. A bank employee mistakenly put $20 bills into the $10 bill slot. As a result, students received several hundred dollars in free money before the bank caught its error, yesterday afternoon. Many students apparently knew about the mistake as the line to withdraw money remained very long all day yesterday. From dead cats to aerobics: Our elixirs haven't changed CHICAGO - Bran for breakfast and aerobics in the afternoon may not sound like folk medicine, but one researcher says they're simply the latest in a long line of remedies that includes Huck Finn's cure for warts - throw a dead cat at the devil. Huck's cure, first shared by Mark Twain in "The Adventures of Tom Sawyer," is recounted by researcher James Whorton in a review of America's fascination with folk remedies in last week's Journal of the American Medical Association.
