Stitching Wounds Using Lasers

We know lasers cut things, but now they're being used to stitch things up too? Doctors at Tel Aviv University have figured out a way to weld skin shut by meticulously control a laser's heat.


The scientists discovered that this method of mending makes the skin less likely to tear and is much more watertight than traditional needle and thread stitches. So far, experiments on real patients have found that the wounds heal faster and with less scaring.

They're hoping that their invention will be in operating rooms around the world in a few years. [Reuters]
