Doing a broader take on the "frog story", the Chronicle investigates the story of corporate influence in conflict with the values of scientific integrity and independent academic research. The "frog story" goes thus : After being hired by a pesticide manufacturer to study the effect of atrazine on frogs, Tyron Hayes - a Univ. of California professor- began to suspect that the company was trying to suppress his findings because they might threaten the re-approval of the product by the Environmental Protection Agency. After Mr. Hayes broke with his research sponsor, Syngenta, other academic scientists who continued to work for the company attacked his work. Allies of the company from the agriculture industry and critics of the environmental regulation also moved to discredit him.
