Two China-based researchers were charged with smuggling Fusarium graminearum, a toxic crop fungus considered a potential agroterrorism weapon, into the U.S. for research at a University of Michigan lab. The case involves Chinese government funding, visa fraud, and CCP ties. The university says it had no knowledge or funding link, and is cooperating with federal authorities. The fungus causes major crop damage and health risks, triggering national security concerns and renewed scrutiny of foreign research access at U.S. institutions.
