...addition to the occasional painful sunburn, long-term exposure to the sun, especially between 10 a.m. and 3 p.m., weakens the skin's elasticity and brings on premature wrinkling and sagging. Of greater concern, it causes as many as half a million new cases of skin cancer every year. Most of these are basal or squamous cell carcinomas, which have high cure rates. But solar radiation may be a cause of melanoma, which can be fatal. Ultraviolet light apparently weakens the immune system; after a severe sunburn, some people suffer outbreaks of oral herpes or other disorders. Excessive exposure aggravates...
More important, the plan might actually lead to more breathable air. It calls for a 50% slash in acid-rain-producing sulfur-dioxide emissions by the turn of the century, a 40% tightening of emissions standards for hydrocarbons from automobile tail pipes, a 75% cut in cancer-causing toxic chemicals poured into the atmosphere over an unspecified period, and in its most visionary -- perhaps pie-in-the-sky -- aspect, a fleet of cars that run on fuels cleaner than gasoline (probably methanol, though ethanol or compressed natural gas could also be used). Some 500,000 such cars would...
...biology." Maybe so, but it will hardly make genetic engineering a kitchen-table technology. Advocates of gene transplants have long pointed to the potential benefits of altered animals -- disease-resistant pigs, fast-growing cows and the like. Medical researchers are already using engineered mice to study the mechanics of cancer and heart disease. But genetic engineering is a process that involves many difficult steps, and the new breakthrough will at best simplify just one of them...
...most promising medical application, doctors are beginning to time medication to match biological cycles. Some experts believe the effectiveness + of cancer treatments can be boosted -- and the harmful complications of the often toxic drugs lessened -- by taking advantage of daily rhythms in the immune system and cell division. Painful bouts of rheumatoid arthritis occur most frequently in the morning, when natural anti-inflammatory agents are least active; aspirin affords the best relief when taken the night before. On the other hand, the time to take medication for osteoid arthritis is midday; joints become inflamed with movement, and pain occurs later...
...been rumored to be dying of a heart condition or cancer for much of the past decade, the Ayatullah Ruhollah Khomeini, 89, has displayed remarkable longevity. Last week, though, doctors performed surgery on the religious leader to stop what was officially described as "bleeding in his digestive system." Providing a rare and somewhat bizarre glimpse at the Imam's private life, Iranian television actually broadcast scenes from the operating room...
