A new study has found that exposure to arsenic -- a cancer-causing element emitted in large quantities by coal-burning power plants and other industrial facilities -- made mice more likely to experience the most severe effects of swine flu. So why are some lawmakers fighting regulations that would better protect Americans from arsenic pollution? More...
