Science: Israel Performed Pioneer Sunlight Surgery

Doctors in Israel have successfully used sunlight to perform surgery on rats.

The procedure would only work in sunny climates, but could one day provide a low-cost alternative to conventional laser treatments.
Laser surgery is used often to remove tumours by simply burning them out instead of traditional techniques of physically cutting them out of the body with a scalpel. This latest research shows it could be possible to produce similar results with concentrated sunlight instead of costly laser treatment.

Surgeons from Ben Gurion University in Israel transported sunlight into the operating theatre from outside through a system of optical fibres. These concentrated rays, which contained several watts of energy were then directed on to the livers of two rats for just a few minutes.
The tissue was seen to wither and die in the same way as it would after laser treatment.

The rats recovered well following the surgery and after detailed analysis of the livers scientists found the treatment had worked as well as a laser.

Not only could this solar surgery be a cheap alternative to laser therapy in sunny countries -- it also appears to be safer for the surgeons to use.
