CONTAMINANTES

U.S. Is Losing Its Dominance in the Sciences: Foreign advances in basic science now often rival or even exceed America's, apparently with little public awareness of the trend or its implications for jobs, industry, national security or the vigor of the nation's intellectual and cultural life.
"The rest of the world is catching up," said John E. Jankowski, a senior analyst at the National Science Foundation, the federal agency that tracks science trends. "Science excellence is no longer the domain of just the U.S." [...]
One area of international competition involves patents. Americans still win large numbers of them, but the percentage is falling as foreigners, especially Asians, have become more active and in some fields have seized the innovation lead. The United States' share of its own industrial patents has fallen steadily over the decades and now stands at 52 percent.
A more concrete decline can be seen in published research. Physical Review, a series of top physics journals, recently tracked a reversal in which American papers, in two decades, fell from the most to a minority. Last year the total was just 29 percent, down from 61 percent in 1983.
Another downturn centers on the Nobel Prizes, an icon of scientific excellence. Traditionally, the United States, powered by heavy federal investments in basic research, the kind that pursues fundamental questions of nature, dominated the awards.
But the American share, after peaking from the 1960's through the 1990's, has fallen in the 2000's to about half, 51 percent. The rest went to Britain, Japan, Russia, Germany, Sweden, Switzerland and New Zealand.
China, said Martin Blume, the journals' editor, has surged ahead by submitting more than 1,000 papers a year. "Other scientific publishers are seeing the same kind of thing," he added.
