Maybe, I fear, I have seen more than just some early-season rust, or a pure statistical anomaly...
Lovley's dual pursuits of scientific exploration and natural surroundings led him straight to the discovery of a group of remarkable microbes he named Geobacter, which breathes rust instead of oxygen, thrives in polluted earth and can even generate electricity. When Lovley first found Geobacter in silt beneath the Potomac River in 1987, he had no idea how capable it was. "I never thought it would go this far," says Lovley. "But Geobacter can do so many things...
Geobacter's secret is its unique metabolism: the microbes expel electrons outside their cell walls without needing to convert them to water, as human cells do. Geobacter needs only an outside compound--usually iron oxide, or rust--to accept the excess electrons. Lovley discovered how to coax Geobacter into not only dumping electrons onto uranium waste but also consuming petroleum by-products. Geobacter has already effectively decontaminated a uranium mine in Colorado and an oil spill in Minnesota...
...combination of the rust Harvard accumulated over its nearly two-month layoff for winter break, reading period and finals and its surprise at Dartmouth’s strength made the match somewhat tougher than it otherwise might have been...
