40 Years of Superconductor Science Just Got Turned Upside Down by a Stunning Discovery

A material that carries electricity without resistance may be held back by its own structure, challenging 40 years of assumptions about copper-based superconductors. A crystal that scientists thought had the same structure throughout is actually a patchwork of two subtly different arrangements of atoms. The boundaries between those regions are hundreds of times wider than [...]
