Febuary 26 2007, Weizmann institute scientist discover a group of genes that slow cell division and prevent cancer. In Rehovot, Israel Cancer and normal cells divide diffrently. When a normal cell gets a signal to divide, It activates a Braking system. That stops cell division and returns the cell to a resting state. When the braking system is faulty, uncontrolled cell division and growth of cancer can begin. Weizmann institute scientist studied this system of brakes, and identified the number of genes involved.
