...clue to the activity of viruses emerged during World War I, when a British and a French scientist independently noticed the appearance of clear circular spots in laboratory cultures grown over with bacteria. When material from a clear spot was applied to a different location in the bacteria culture, another circular area devoid of bacteria soon appeared. Felix d'Herelle, the French bacteriologist, thought he knew why. "What caused my clear spots," he wrote, "was in fact an invisible microbe, a filterable virus, but a virus parasitic on bacteria." D'Herelle named the unseen bug a bacteriophage (from the Greek...
Antarctica is not the only spot where ozone levels are low, says Donald Heath, a NASA scientist. Tests over Arosa, Switzerland, since the 1920s have shown an average ozone loss of 3%, mostly in the past ten years. And Heath believes he has found another hole. Centered over Spitsbergen, Norway, 700 miles from the North Pole, it is one-third the size of the Antarctic hole. Heath claims the region's ozone loss has been 1.5% a year for the past six years and says this location fits models of CFC-caused loss...
...Antarctic team's assertions are bold, since the tests are not completed. But even if the ozone change is not induced by man, says NASA Research Scientist Richard Stolarski, "it would do us well to understand, because we're going to have to react whether it's natural or man-made. We need to know if these changes are greater than in the past or if we are just paying more attention to them now. And we should know that as soon as possible...

Weary, pale and on a stretcher, the white-haired 67-year-old scientist offered his explanation: "A miracle happened...
