Novembfr 12. 178 SUNDAY, Binghamton, N.V. 9-A I WINTER Star blast theory for dinosaur fall When cosmic rays hit the atmosphere, they release nitrogen atoms that react with oxygen and produce nitrogen oxide compounds. These are efficient destroyers of ozone, the form of oxygen 10 to 30 miles high that screens out much of the sun's harmful ultraviolet radiation. Based on today's understanding of atmospheric chemistry, the three scientists calculated that a thousand-fold increase in cosmic radiation would reduce the total ozone by 80 percent.

Nitrogen dioxide would be 130 times more abundant. I Their report, released yesterday, said such decreases in ozone would allow 10 times more ultraviolet radiation to reach Earth's surface. was a very big wipe out. It affected almost everything." Dr. George Reid The nitrogen dioxide would filter out much of the blue and green parts of visible light, with this overall chain reaction effect: A significant drop in global surface temperature, drastic reductions in atmospheric water vapor and, finally, widespread drought In addition, the scientists said reduction in light reaching Earth would cut photosynethesis, the process by which green plants manufacture their food from carbon dioxide and water.

These effects could cause a severe decrease in the abundance of plant life the food for dinosaurs and many other animals. Whether all this happened and caused the sweeping extinctions is speculation. But the scientists said a nearby supernova is an event that "may well have occurred several times within the billion-year existence of life on "I think our contribution is to raise the whole question again because of the climatic effects," Reid said. By AL ROSSITER JR. UPI Science Editor WASHINGTON The extinction of the dinosaur 65 million years ago may have resulted from environmental changes brought about by the explosion.

of a star, scientists suggested yesterday. The theory is a new twist to an idea debated and then discounted in the 1960s, suggesting Earth may have passed through the radioactive remains of a supernova a large star that exploded and left an expanding cloud of turbulent gases. believe supernova remnants are the sources of galactic cosmic rays that constantly bombard Earth's upper atmosphere. was originally suggested that, if Earth passed through a supernova remnant, the cosmic rays might have been strong enough to kill many forms of life. Or.

George Reid of the National Oceanic and Atmospheric Administration said estimates from geologic evidence indicate perhaps 75 percent of all species -r including thousands of other animal types besides dinosaurs became extinct at roughly the same time. "It was a very big wipe out," he said in a telephone interview from his office at the agency's Aeronomy Laboratory at Boulder, Colo. "It affected almost everything." 'Reid said, however, that direct radiation from supernova remains would not account for the wholesale extinction. Even if the cosmic ray barrage were increased 1,000 fold, not enough would penetrate Earth's atmosphere to be so lethal. But Reid, Dr.

John McAfee of the Aeronomy Lab and Dr. Paul Crutzen of the National Center for Atmospheric Research suggest the cosmic rays could have the same impact by working a different way. 11 mtmmrmmmmmmtmmmm wi'w "IV.

"We thank him for his greater vision that did not let the world pass by under clouds of ugliness." Approximately 100 townspeople attended the ceremony. Officiating was the Rev. Theodore H.

Evans, rector of St. Paul's. Out-of-towners present included Ernest Hall, whom Rockwell depicted in a 1959 painting titled "Expense Account," and Frank Tchiskie who in 1919 appeared on a Rockwell canvas as a little boy taking a dip in a "No Swimming" area. Rockwell's third wife, Molly, and his three sons, Thomas Peter and Jarvis and several grandchildren, sat near the artist's coffin, which was covered with a cross of white silk and red velvet. STOCKBRIDGE, Mass.

(UPI) Artist Norman Rockwell, who captured the American ideal with often whimsical illustrations, was eulogized at his funeral yesterday as a man who "did not let the world pass by under clouds of ugliness." Every seat at St. Paul's Episcopal Church, a small greystone house of worship in the center of this picturesque Berkshire County community, was filled while an estimated 200 other persons stood outside in quiet tribute to one of America's most beloved artists. Rockwell, who had been in poor health for the last several years, died in his sleep Wednesday night at the age of 84. His final painting, titled "John Sargeant and the Indian" was left resting on his easel unfinished. "Our friend and neighbor has died, and as Christians we can only rejoice that all game variations and options than anyone else.
