A clever nanoscale redesign may have solved one of superconductivity’s biggest problems. Researchers in Sweden discovered that by subtly sculpting the surface beneath an ultrathin superconducting material, they could make it stay superconducting at higher temperatures and under much stronger magnetic fields. The advance could help move superconducting technologies closer to practical use in electronics, energy systems, and quantum devices. Modern digital devices, data centers, and information and communications technology (ICT) networks are responsible f... [5821 chars]
