When electricity moves through wires, some of its energy is lost along the way. That loss, however, might not be inevitable. Researchers at Penn State have developed a new way to identify materials known as superconductors — substances that can carry electric current with zero resistance, meaning no energy is wasted during transmission. The Challenge…
