For decades, scientists quested after a room-temperature superconductor. Now that they’ve finally found one, the hunt is on for an even better material. Until last year, all known superconductors — ...

Have you ever heard of metallic hydrogen? Probably not, because it has only ever existed in theory. Harvard scientists have recently created metallic hydrogen from applying extremely high pressure to ...
