Facebook blocks unlicensed gun sales (Update)

Facebook has banned people using the social network for unlicensed gun sales after pressure from anti-gun violence groups alarmed over the ease with which firearms are sold online in the United States.

Solving problems on a quantum chessboard

Physicists at the University of Innsbruck are proposing a new model that could demonstrate the supremacy of quantum computers over classical supercomputers in solving optimization problems. In a recent paper, they demonstrate ...

Ultracold atoms point toward an intriguing magnetic behavior

Using atoms cooled to just billionths of a degree above absolute zero, a team led by researchers at Princeton University has discovered an intriguing magnetic behavior that could help explain how high-temperature superconductivity ...
