Superconductors (materials that conduct electricity without resistance) have fascinated physicists for more than a century.

Transistors are fundamental to microchips and modern electronics. Invented by Bardeen and Brattain in 1947, their development is one of the 20th century's key scientific milestones. Transistors work ...

Researchers at the Niels Bohr Institute, University of Copenhagen, steered very thin conductors from superconductivity to insulation—creating an "impossible," strange state between the two mutually ...
