A new look at `strange metals`
(PHYSorg.com Physics)

Superconductors allow electrical current to flow without any resistance-but only below a certain critical temperature. Many materials have to be cooled down to almost absolute zero, while some materials keep their superconducting properties up to much higher temperatures. How this `high-temperature superconductivity` works and how it is possible to develop new materials that are superconductors even at normal room temperature is still one of the great mysteries of modern physics.
