Israelis Shed New Light on Fighting Tumors

Scientists in Israel say they hope to use highly concentrated light from commercial light bulbs to fight tumors, providing an effective and cheap replacement for laser surgery. In a study recently published in the Journal of Biomedical Optics, Jeffrey Gordon of Ben-Gurion University showed that light from an ultra-bright commercial bulb, similar to that used in movie projectors, could be concentrated by a special optical system to burn away tissue in rats.
