Superconductivity is a remarkable phenomenon: superconductors can transport electric current without any resistance and thus without any losses whatsoever. It is already in use in some niche areas, for example as magnets ...

(PhysOrg.com) -- An infrared laser developed by Arizona company Raytheon Missile Systems has been demonstrated shooting down incoming drones over the ocean off the coast of California.
Unlike fictional laser swords, real laser beams do not interact with each other when they cross—unless the beams meet within a suitable material allowing for nonlinear light-matter interaction. In such a case, wave mixing ...
