A phenomenon of solid-state physics known as "pseudogaps," suspected by some scientists of playing a key role in the mystery of high-temperature superconductors, has now been found to occur in materials of a completely different nature. This discovery casts new doubts on any direct link between pseudogaps and high-temperature superconductivity.
