<description><![CDATA[ Gold is a unique element that has been almost universally treasured. It's rare, but it isn't the hardest element to find. Gold has a remarkable property of not reacting with its environment, so it doesn't tarnish or burn. There aren't that many practical uses for it, compared to other metals, though, but here are a few links on some gold-related items.

<ul>

<li> <a title="http://news.msu.edu/story/superman-strength-bacteria-produces-gold/" href="http://bit.ly/OPjMvQ">Microbial alchemy doesn't transmute lead into gold, but it does metabolize gold chloride (aqueous) into solid 24-karat gold.</a> <i>Cupriavidus metallidurans</i> can tolerate highly toxic concentrations of gold chloride and reduce the metal so that it precipitates.

<li> <a title="http://www.economist.com/node/21552218?fsrc=scn/fb/wl/ar/allthatglisters" href="http://econ.st/SJW8Ss">Gold medalists at the last Olympics didn't receive solid gold for their efforts but mostly silver with a gold coating.</a> So in all those pictures of the athletes biting on their gold medals, that bite test for metal purity had a pretty good chance of failing.

<li> <a title="http://creativetime.org/projects/the-last-pictures/" href="http://bit.ly/RMdgV0">The Last Pictures project is planning to preserve a visual record of human civilization on a silicon disc encased in gold -- for billions of years.</a> This archival disc will be launched with the EchoStar XVI satellite and should remain in orbit for longer than our planet, as we know it, will exist.
