Last year, researchers at the University of Pennsylvania Medical Center found that brain cells continue to die for weeks to months after sustaining injury. Now, these investigators have found that a cell's ability to detect damage to DNA in its nucleus is also impaired for months after an injury. The DNA in human cells is assaulted everyday by all sorts of damaging agents -- ultraviolet radiation, chemicals, and heat, for example -- but normally the body has a vigilant surveillance system in place to detect damage and quickly repair it.
