The amazing camera that can see around corners (w/ video)

How can a person see around a blind corner? One answer is to develop X-ray vision. A more mundane approach is to use a mirror. But if neither are an option, a group of scientists led by Genevieve Gariepy have developed a ...

First germanium laser brings us closer to 'optical computers'

(PhysOrg.com) -- MIT researchers have demonstrated the first laser built from germanium that can produce wavelengths of light useful for optical communication. It’s also the first germanium laser to operate at room temperature. ...

Physicists show that superfluid light is possible

(PhysOrg.com) -- Superfluidity – the phase of matter that enables a fluid to move up the sides of its container – has been known about since the 1930s. Since then, superfluidity has become a prime example of how ...

Physicists discover 'smoke rings' made of laser light

Most basic physics textbooks describe laser light in fairly simple terms: a beam travels directly from one point to another and, unless it strikes a mirror or other reflective surface, will continue traveling along an arrow-straight ...
