Scientists have demonstrated, for the first time, highly directional semiconductor lasers with a much smaller beam divergence than conventional ones. The innovation opens the door to a wide range of applications in photonics and communications.

Researchers at the California Institute of Technology have turned science fiction into reality with their development of a super-compact high-resolution microscope, small enough to fit on a finger tip.

Cut off one finger from a salamander and one will grow back. Cut off two and two will grow back. It sounds logical, but how the salamander always regenerates the right number of fingers is still a biological mystery.

University have found that birds such as the Cirl Bunting and Dartford Warbler are becoming more common across a wide range of habitats in Britain as temperatures rise.

A new technique allows pictures which were later painted over to be revealed once more.

Cardiff University experts have led an international team in unravelling the secrets of a 2,000-year-old computer which could transform the way we think about the ancient world.

Hundreds of insect species spend much of their time underwater, where food may be more plentiful. MIT mathematicians have now figured out exactly how those insects breathe underwater.
