Scientists learn the secret of a famous anti-superconductor

Magnetite is, as its name implies, one of the most naturally magnetic materials on earth. Millennia ago, it was what first clued scientists in to magnetism. But magnetite is also something of a mystery. At low temperatures, the rock completely stops all electricity. At last scientists have figured it out why. » 12/23/11 7:20am 12/23/11 7:20am

String theory and black holes show a possible path to practical…

A leading candidate for room temperature superconductors is the copper compound cuprate, but no one knew how cuprates facilitated superconductivity...until some brave souls looked inside a black hole and broke out the string theory to explain how they work. » 8/06/10 10:00am 8/06/10 10:00am
