...OZONE LAYER THINS, PEOPLE MAY SPEND more time indoors to avoid the skin cancers and cataracts likely to result from more ultraviolet light reaching the earth's surface. That strategy could backfire. Like the sun, the high- intensity quartz-halogen lights used increasingly in homes and offices emit ultraviolet as well as visible light, and there is now evidence that they, too, can cause skin cancer...
...having helped murder hundreds of thousands of Jews as a Nazi death-camp guard known as Ivan the Terrible. There is considerable evidence that Buchanan may be right that Demjanjuk could not have been the mass murderer of Treblinka. But Buchanan has also claimed that diesel engines do not emit enough carbon monoxide to kill anybody, much less 850,000 people at Treblinka; that the U.S. should not have apologized to France for protecting Nazi war criminal Klaus Barbie; and that Arthur Rudolph, the ex-Nazi rocket scientist forced to leave the U.S. after the Justice Department accused...
Pulsars are fast-spinning, ultra-dense clumps of neutrons -- generally the husks of stars that have exploded. They get their name from the powerful radio pulses that they emit at precisely regular intervals. It was an anomaly in these pulses that led the Manchester astronomers to focus on one particular pulsar -- and convinced them that a planet whirled around it. The pulsar spins on its axis three times a second, raking the earth with a beam of radio waves each time. But, says Lyne, periodically "the pulses would arrive about one- hundredth of a second earlier than they should...
...road. It doesn't have a gas tank. It uses little oil. And it gets 120 miles with each fill-up. Miles ahead of its time, the Impact is an electric car that runs on 32 10-volt batteries. Since it burns no fuel, no tail pipes emit noxious fumes into the atmosphere. Though the car is experimental, GM last week announced it would produce it in a plant that can turn out 25,000 autos a year, signaling the company's most ambitious venture yet in electric vehicles...
...government is paying $210,000 to find out whether burping cows contribute to global warming. Researchers will strap monitors near the cud-chewing creatures' mouths to measure how much methane they emit. Flatulence is considered a comparatively minor source...
