Yale researchers have discovered how the "guardian of the genome'' oversees quality control in the production of sperm - and perhaps in many other cells as well. The research published online in the journal Current Biology opens up the potential of developing new forms of birth control and fertility treatment - and even new ways to combat many forms of cancer. Sperm and other cells go through a sort of inspection process triggered by a key regulatory gene, p53, which orders the destruction of cells with damaged DNA...
