Unexpected Boost: A superconductivity killer’s silver lining

A bad neighbor sometimes has a good influence on the folks next door. Superconductivity researchers are discovering their own version of this experience.

Physicists have long been wary of ordinary metals that, when they share physical borders with superconductors, sap their neighbors of their no-resistance conductivity. This phenomenon is known as the proximity effect, and scientists have now found its opposite.
