Scientists detect 'fingerprint' of high-temp superconductivity above transition temperature

A team of U.S. and Japanese scientists has shown for the first time that the spectroscopic 'fingerprint' of high-temperature superconductivity remains intact well above the super chilly temperatures at which these materials carry current with no resistance. This confirms that certain conditions necessary for superconductivity exist at the warmer temperatures that would make these materials practical for energy-saving applications - if scientists can figure out how to get the current flowing...
