Ultrashort light pulses for fast 'lightwave' computers
Extremely short, configurable "femtosecond" pulses of light demonstrated by an international team could lead to future computers that run up to 100,000 times faster than today's electronics.

(Phys.org)—It was another good week for physics as Ian Shoemaker, until recently with the University of Southern Denmark, proposed a new theory, suggesting that if we want to detect dark matter, we might need a different ...
It was a very interesting week for physics as experiments at the LHC showed that a particle known as the "beauty quark" behaved as has been predicted by the Standard Model and thus represented a new blow for the "supersymmetry" ...
More luminous and energy efficient than LEDs, white lasers look to be the future in lighting and light-based wireless communication.
