Slashdot links to a Thinq article that explains researchers led by the University of Ohio have discovered a superconductor made up of as few as four pairs of molecules. As the story goes on to explain, one of the problems with building devices at the nanoscale is that traditional interconnects produce too much heat as the element size shrinks, a function of electrical resistance. The heat produced by such traditional metallic interconnects can melt the components to which they connect.
A superconductor as an alternative makes sense as resistance is exactly zero, eliminating this overheating problem. What the article does not explain is at which temperature this material superconducts. Traditionally, superconductors only exhibit this much desired quality at very low temperatures. If true, here, it would sort of defeat the point.
