Physicists have demonstrated with unprecedented accuracy that the speed of light remains constant. In 1887, a landmark physics experiment was carried out by American researchers Michelson and Morley.

In a cafe at CERN in 1992, three physicists realized they disagreed about how many constants are needed to describe all of nature. A recent paper suggests only one – time – is necessary.

For experimental physicists, the latest measurement of the muon is the best of times. For theorists there's still work to do.

In 1887, one of the most important experiments in the history of physics took place. American scientists Michelson and Morley ...

A woman says she’s been left terrified to ever visit the dentist again after a botched dental job left her in constant pain and too ashamed to show her teeth. Sadie Hobson, 47, claims her mouth was ...
