The Daily Princetonian reports on a study measuring the effects of years of anti-research politics in the US: "The United States' share of new publications in stem cell research is unexpectedly low and declining, according to a recent paper by Aaron Levine, a doctoral candidate in the Wilson School. The paper speculates that the U.S. political environment may be a factor. ... The United States' share of embryonic stem cell publications was 30 percent, compared to an average of 51 percent for five other biomedical technologies including DNA microarrays, polymerase chain reaction, yeast two-hybrid screening, green fluorescent protein expression tagging and RNA interference."
