    Hmm, seems like it's not as amazing as it sounds. The compound they are transforming into gold is "gold chloride".

    "The team was led by Kazem Kashefi, assistant professor of microbiology and molecular genetics. Working along with Adam Brown, associate professor of electronic art and intermedia, the team discovered that the metal-tolerant bacteria Cupriavidus metallidurans can grow on massive concentrations of gold chloride – or liquid gold, a toxic chemical compound found in nature."

    The dream of alchemy was to turn base metals like lead into noble metals like gold. I'm not sure transforming a compound containing gold and chlorine into pure gold is the same kind of thing. Pretty cool though.

    "Alchemy is an influential philosophical tradition whose early practitioners' claims to profound powers were known from antiquity. The defining objectives of alchemy are varied; these include the creation of the fabled philosopher's stone possessing powers including the capability of turning base metals into the noble metals gold or silver, as well as an elixir of life conferring youth and immortality."

    This will make the price of "real" gold skyrocket.

    This is only a miracle for morons . Gold chloride is a gold solution. It's easy to have it precipitate out of solution and it's more expensive than gold.

    er... not. This was "discovered" back in the 90's. It's now thought that most placer gold is probably produced in stream sediments by microbes. Generations of minors were on the wrong track, trying to follow the stream back to "the mother load." (Except that there had to be gold-rich rocks upstream somewhere, to supply the microbes in the first place.)
