Maybe the color of the Nobel Prize medal should be changed from gold to red, white and blue. U.S. researchers swept the science awards for the first time since 1983. But the joy came with a warning from many in the U.S. scientific community: the kind of basic research that won Nobels is no longer getting adequate funding. Without more funds, they argue, U.S. scientific dominance won’t last, as other nations become more competitive in these cutting-edge fields.
