News : Sci-fi laser stiches wounds

It could be a scene from a sci-fi movie -- doctors instantly sealing a patient's wounds using little more than a laser beam.

A group of scientists from Tel Aviv University have discovered that by meticulously controlling a laser's heat they can use it to weld the skin shut.

This method of mending means the skin is less likely to tear and is more watertight than traditional needle and thread stitching of a wound.

Experiments on real patients in Israeli operating rooms have proven successful. Their wounds have healed faster and with less scarring.

The scientists hope to see their invention in operating rooms around the world in a few years time.
