Roger may find interesting this story that is at the nexus of microbiology and metal-love. Science story at The Week out today , excerpt:
Researchers at Michigan State University have discovered bacteria with the remarkable ability to turn toxic chemical compounds into 24-karat gold. The breakthrough, detailed in a combination art and biotechnology exhibition called "The Great Work of the Metal Lover," [Ed: You can't make this up.] is described by researcher Adam Brown as modern day "neo-alchemy."This part is interesting:
Hmmmmm... imagine gold reduced to bacterial excrement... yuck! State currency doesn't look that bad now does it metal-lovers? At least state currency can never take the form of biological excrement.The details are a bit complicated, says Jesus Diaz at Gizmodo, but basically, "Cupriavidus metallidurans can eat toxins and poop out gold nuggets."
This project interestingly is part of a combination biotechnology and art exhibit that I wonder if Ron Paul perhaps funded with an earmark to the National Endowment of the Arts.
