Alchemy! Superman-strength bacteria produce 24-karat gold

Posted on by Robin Edgar

the metal-tolerant bacteria Cupriavidus metallidurans can grow on massive concentrations of gold chloride — or liquid gold, a toxic chemical compound found in nature. Brown and Kashefi fed the bacteria unprecedented amounts of gold chloride, mimicking the process they believe happens in nature. In about a week, the bacteria transformed the toxins and produced a Read more about Alchemy! Superman-strength bacteria produce 24-karat gold[…]

Authentication Implications in Uniquely Identifiable Graphics Cards | threatpost

The researchers realized that apparently identical graphics processors are actually different in subtle, unforgeable ways. A piece of software developed by the researchers is capable of discerning these fine differences. The order of magnitude of these differences is so minute, in fact, that manufacturing equipment is incapable of manipulating or replicating them. Thus, the fine-grained Read more about Authentication Implications in Uniquely Identifiable Graphics Cards | threatpost[…]
