Scientists from Australia's Commonwealth Scientific and Industrial Research Organisation have discovered that eucalyptus trees in the Australian outback are drawing up gold particles from deep underground through their root system and depositing the precious metal in their leaves and branches. Rather than being a new source of "gold leaf," the discovery could provide a cheaper, more environmentally friendly way to uncover valuable gold ore deposits.
