...country in which medical breakthroughs occur with dizzying regularity, the U.S. has been disturbingly backward in the field of contraception research. Not a single fundamentally new birth-control method has been introduced since the Pill and the IUD, or intrauterine device, came out in the early 1960s. Meanwhile, in several European countries, a series of contraceptive innovations has broadened the range of methods far beyond what is available in the U.S. -- and sharply reduced the number of unwanted pregnancies...
...Protection Agency. In the executive summary of a new scientific review, released in draft form late last week, the EPA has put forward what amounts to the most serious government warning to date. The agency tentatively concludes that scientific evidence "suggests a causal link" between extremely low- frequency electromagnetic fields -- those having very long wavelengths -- and leukemia, lymphoma and brain cancer. While the report falls short of classifying ELF fields as probable carcinogens, it does identify the common 60-hertz magnetic field as "a possible, but not proven, cause of cancer in humans...
...heart of the debate is a simple and well-understood physical phenomenon: when an electric current passes through a wire, it generates an electromagnetic field that exerts forces on surrounding objects. For many years, scientists dismissed any suggestion that such forces might be harmful, primarily because they are so extraordinarily weak. The ELF magnetic field generated by a video terminal measures only a few milligauss, or about one- hundredth the strength of the earth's own magnetic field. The electric fields surrounding a power line can be as high as 10 kilovolts per meter, but the corresponding field induced...
Kuwait could also acquiesce to a final fixing of the disputed Iraq-Kuwait border that would put its two-mile-long share of Rumaila squarely on Iraqi turf. Alternatively, Kuwait could agree to turn its proceeds from Rumaila over to Baghdad. Though the field is extraordinarily bountiful, its loss would not seriously dent Kuwait's oil riches. Prior to the invasion, Kuwait was extracting some 10,000 bbl. a day from Rumaila, just 0.5% of its total production of 2 million...
...drugs. This fall a pair of psychologists at the Walter Reed Army Medical Center in Washington began selecting and dispensing medications to a handful of patients in an experiment to see if novice prescribers can do the job safely and effectively. The test marks the first time in the field of mental health that non-M.D.s have been permitted to prescribe medication. Last week the American Psychological Association showed its confidence that the experiment will be a success by appointing a study group to explore university curriculum changes that would teach psychology students the art of prescribing...
