Report on Contaminated Wild Maize Rejected

Scientists have cast doubt on claims that genetically modified corn has contaminated wild maize grown in a remote area of Mexico. Ignacio Chapela and David Quist of UC Berkeley had reported in the journal Nature about finding traces of transgenic DNA in the maize. The research sparked calls for a global ban on genetically modified crops. But other researchers said last week that the study was flawed and the conclusions wrong. The editors of Nature said the study should never have been published because of flaws in its methodology.
