Subatomic particles clocked at speeds exceeding the speed of light may have been going even faster than they appeared, physicists say.

Physicists hunting for the elusive Higgs boson at an American accelerator have come up with similar findings to researchers at the Large Hadron Collider in Europe.

European researchers say they have discovered a new subatomic particle that helps confirm our knowledge about how quarks bind – one of the basic forces in the shaping of matter.
