Gov. Kathy Hochul must decide by year’s end whether to sign a law that would mandate two-person crews on all trains, a ...

The world’s growing need for cleaner travel comes from worsening environmental problems. Though electric cars powered by ...

Superconductivity occurs when electrons pair up, rather than scattering apart as they do in normal conductors or in everyday ...

Physicists have discovered how to make electrons “freeze” and “melt” into bizarre quantum patterns, forming a new kind of matter where solid and liquid coexist. Electricity drives nearly every aspect ...

Thinking of tackling electrical repairs but don’t know where to start? With just a little knowledge–and less than $100 worth ...

A grid is considered resilient when it can either withstand the effects of severe weather or, if severe weather does stop it from functioning, when it is able to “bounce back” and restore electricity ...

Major battery breakthroughs seemingly happen every day, but only some of that tech ever leaves the lab. WIRED breaks down ...

In 1851, physicist William Thomson (also known as Lord Kelvin) noticed that when an electric current runs through a conductor ...

In a metal like copper, however, the outer electrons swim around freely and are shared by all the atoms. That’s why ...

Penn State scientists have devised a new method to predict superconducting materials that could work at higher temperatures.

Liquid metal embedded with dormant bacterial spores forms a living conductor that heals itself, resists oxidation, and boosts ...
