Colorado State University researchers secured a $2 million federal grant to develop a system for genetically modifying nonfood plants, such as sorghum, for biofuel production. "Right now, most of the fuel we produce in biofuels is from materials that can serve as food for humans and animals. What we'd like to do is move to a set of feedstocks that don't compete with animals and humans," said Eric Toone, deputy director of the Advanced Research Projects Agency-Energy.
