Gamma ray bursts turn out not to be the cause of the strongest cosmic rays, leaving scientists scratching their heads.
As expected, CERN scientists measuring the speed of neutrinos have discovered that the particles aren't traveling faster than light after all.
Scientists have for the first time sent a message using a beam of neutrinos, through 240 meters of solid stone.
An improved re-run of the experiment that appeared to show faster-than-light travel was possible has produced the same result.
European scientists believe they've observed subatomic particles traveling faster than the speed of light - something that Einstein's theory of relativity says should be impossible.
Two new detectors in China have started recording the interaction of antineutrinos in an experiment that could help explain why matter predominates over antimatter in the universe.
