"It's science fiction made real," a doctor from Tel Aviv University told Reuters, as he demonstrated how a new laser the university has developed is better than stitching up a patient. The laser allows a wound to be welded shut as opposed to sutured, which makes it far more watertight and there's less tearing. It's done by very carefully controlling the temperature of the beam, and Israeli patients treated with the laser have already enjoyed faster healing times and less scarring.
