    Move over, corn, oplar trees could one day be used to make biofuels, too. 

    Researchers at the University of Maryland and Bowie State University received $3.2 million in grants to create a poplar hybrid that could be transformed into gasoline for our cars.

    The special trees would be grown and harvested on plantations so existing forests won't be wiped out.  

    Poplars are already used to make paper and timber.

    To keep up with our thirst for gas, researchers said the species would have to grow quickly.

    The National Science Foundation is funding the four-year project.
