Of all the contamination events involving genetically engineered crops, few have received more attention than a UC-Berkely study that brought to light contamination of indigenous Mexican maize varieties. The study was published in Nature magazine in 2001, and ignited so much controversy around its accuracy that Nature rescinded its support of the article, a decision that many believe was a result of industry pressure. But new research shows that the Berkely researchers' findings weren't off base. Last week, Nature published another study that identified contaminated "landrace" maize varieties in the Mexican heartland, this time by researchers at the National Autonomous University of Mexico. Nature reports that the study "largely confirms a similar, controversial result published in Nature in 2001 and may reignite the debate in Mexico over GM crops." Transgenic varieties are currently not approved for commercial planting in Mexico, the center of origin for maize. Acknowledging this fact, the Mexican government banned the cultivation of transgenic maize in 1998 to protect the 60-some native varieties. This hasn't stopped contamination, however, since corn is imported to the country, most of which is genetically engineered, and some Mexican farmers illegaly plant transgenic seed. Ensuring the genetic integrity of native seed is crucial to future research in the face of climate change. It's also important to sustaining a diversity of food sources. Evidence for contamination highlights an important question: do seed technologies have the right to exist at the expense of other varieties? Source: Nature

MBTs are a great tool for athletes. they improve post-workout recovery, reinforce proper posture, and help athletes engage muscles that are often neglected in traditional, sport-specific training.
