A superconducting material allows electrical current to flow through it with perfect efficiency, without wasting energy.

For decades, physicists have dreamed of discovering a material that could effortlessly convey electricity at everyday temperatures, a feat that would save gargantuan amounts of energy and revolutionize modern technology.

For the first time ever, scientists have demonstrated that superconductivity, a state that enables electrical charges to pass through materials with no resistance, is possible at room temperature.

First discovered in 1911, superconductivity gives materials two key properties. Electrical resistance vanishes. And any semblance of a magnetic field is expelled, due to a phenomenon called the Meissner effect.

Physicists from UNLV and the University of Rochester announced a major discovery on Wednesday.

With ballots arriving in the mail and early voting starting this weekend people across Nevada will need to dig into some voter guides.

It is superconducting, which means electrical current flows through it with perfect efficiency - with no energy wasted as heat.

Las Vegas will host an NCAA Tournament men's basketball regional for the first time after the NCAA changed a policy that prevented states with sports wagering from hosting championships.
