This is an amazing story of accidental discovery and it could potentially lead to far-reaching advances in understanding superconductors.

A team of researchers from the University of Illinois Urbana-Champaign and Kyoto University found a weird effect while studying a compound called strontium ruthenate (Sr2RuO4), a crystalline combination of two metals, strontium and ruthenium.

Researchers were shooting electrons at strontium ruthenate, and measuring the energies bouncing off
