Evolution has taken a turn that would make Rumpelstiltskin jealous.  Michigan State has produced a bacteria that takes a highly toxic substance, Gold Chloride and turns it into pure gold.  How amazing is that?  Its almost like in Superman where Mr. S takes a piece of coal and squeezes it until it’s a diamond.  Before you go investing in a bioengineering degree, Gold Chloride is hard to produce and is expensive.  Still, this is pretty amazing stuff.
