A cause for 'strange' behavior of cuprates discovered, with superconductor ramifications

A recent study published in Nature Communications by researchers from Politecnico di Milano, Chalmers University of Technology in Göteborg and Sapienza University of Rome sheds light on one of the many mysteries of high-critical-temperature copper-based superconductors. Even at temperatures above the critical temperature, they are special, behaving like "strange" metals. This means that their electrical resistance changes with temperature differently than that of normal metals.
