INVASIVES -- In the most convincing proof to date that there IS a God -- scientists say they've found a super hero capable of turning the tide against cheatgrass.

USDA researcher finds soil bacteria that is the scourge of cheatgrass
Cheatgrass is the single worse invasive species in the American West, colonizing so many acres that it can be seen from space, but a U.S. Department of Agriculture researcher has found a way to take on the intruder. After three decades of research,  a soil bacteria that can attack cheatgrass at its roots has been detected. Now the challenge is finding a delivery system of the live bacteria that works for the hundreds of millions of acres where cheatgrass rules.
