Just because it hasn't happened yet, doesn't mean it can't; at least that's what a Scottish research group is hoping as it attempts to create reproductive synthetic cells made completely from metal. At this stage, the idea of sentient metallic life remains a distant sci-fi dream, but researchers at the University of Glasgow have already birthed iChells -- inorganic chemical cells. These bubbles, formed from the likes of tungsten, oxygen and phosphorus, can already self-assemble, possess an internal structure, and are capable of the molecular in-and-outs expected of its biological counterparts. Researchers are still tackling how to give these little wonders the ability to self-replicate, and possibly evolve -- further cementing our doom post-Robot Apocalypse
