The U.S. science Ph.D. seems to have hit a wall--hard. After decades of
expansion, the number of scientists seeking research grants and research jobs
appears, in the eyes of many, to have outstripped the money available to supply
them. Cell biologist Richard McIntosh, former president of the American Society
for Cell Biology, has described the situation as a "Malthusian crisis." This
special issue of Science examines the many effects of this crisis, from calls for
Ph.D. "population control" to changes in graduate programs to make their
graduates more marketable in an uncertain future.
