...minute drive from Reykjavik, and set dramatically in a wilderness of moss-covered rocks. On a cold day its milky blue waters resemble a misty version of Heaven. Spa options range from massages on a float in the water to a facial with the lagoon's silvery-gray silt, which is said to have healing properties. Inevitably, there's also a boutique selling the Blue Lagoon's very own cosmetics, and an excellent seafood restaurant. Warning: stray too close to the lagoon's source while having a soak, and you'll quickly learn just how hot Iceland is beneath...

Poorly maintained embankments burst, and irrigation channels and dams that had been allowed to choke with silt trapped the flood on the land...
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...
