Scientists Find GMO ‘Kill Switch’
Genetically modified organisms just got less scary. Biologists at Harvard and Yale say they have designed a technique to confine engineered genes found in GMOs by keeping them from intermixing with wild organisms. The researchers created bacteria that could survive only on lab-grown amino acids, a dependence that would prevent them from spreading uncontrollably into the wild via bees or the wind. The technique could be instrumental in providing a safer method for using genetically modified bacteria in the development of foods, medicines and fuels.
