Superconductivity: Lifting the gossamer veil
Piers Coleman1

Abstract
Copper oxides become superconductors at much higher temperatures than conventional metals. This transition might involve a state of 'gossamer' superconductivity, and new work shows how.
One of the outstanding mysteries in condensed-matter physics is that the most perfect conductors so far discovered — the high-temperature superconductors — are more like insulators than metals. Superconductivity, the flow without resistance of current through some materials, usually only occurs at very low temperatures.
