Physicists studying high-temperature superconductivity have tended to discount an idea that has hovered at the fringes of the field for several years--that charges percolate back and forth through these materials in a series of stripes, a few atoms wide, creating a landscape that helps current flow effortlessly through the material in all directions. But recent reports are persuading many physicists that the charge stripes are real. Whether or not they have anything to do with superconductivity, however, is still vigorously debated.
