[JURIST] In a turnaround from its position just a day earlier, the Environmental Protection Agency [official website] canceled a controversial study Friday involving the effects of pesticides on children. The EPA had planned to seek the advice of outside scientific experts before making a final determination on the suspended CHEERS [EPA study website] study, but mounting pressure from Democrats willing to block the confimation of the agency's new head Stephen Johnson [EPA profile] helped to end the study before it began. Johnson, nominated last month [JURIST report], is the first person with a science background to be picked to lead the agency. The Senate Environment and Public Works Committee [Official website] announced Friday it would meet again next week to consider his nomination. JURIST's Paper Chase has background here. The CHEERS website now carries a cancellation notice from Johnson. AP has more details on the cancellation.
