The Unusual Insulating Properties of a Superconductor

Since their discovery, high-temperature superconductors, a class of remarkable materials that conduct electricity with almost zero resistance, have perplexed scientists. Despite many, many studies, how these materials do what they do is still not well understood. At the National Synchrotron Light Source, scientists have discovered a perhaps odd, yet important clue to the puzzle - that a common high-temperature superconductor actually has distinct insulating properties.
