Last week the Union of Concerned Scientists (UCS) released updated evidence that the Bush administration continues to manipulate and control science for political reasons. UCS has now collected the signatures of more than 4,000 scientists supporting a statement urging the Bush administration to discontinue these troubling practices, and to restore scientific integrity in federal policymaking. The prestigious list of scientists taking this unprecedented stand includes 48 Nobel laureates, 62 national medal of science recipients, and 127 members of the National Academy of Sciences.
