chinese scientists charged toxic fungus.

Two scientists from China have been charged in Michigan in what the FBI says was an effort to bring a toxic fungus to the U.S. Investigators say the pathogen can attack wheat, barley, maize and rice and sicken livestock and people. The scientists are charged with conspiracy, smuggling and other crimes. Only one is still in Michigan. The other was turned away at the Detroit airport last July and sent back to China after red plant material was discovered in his backpack.
