ONLINE COVER Surviving a Brush with Radiation. The brushlike structure in this illustration is that of intestinal villi, a tissue that is particularly susceptible to radiation-induced damage. Although damage to the bone marrow and hematopoietic system is the better known risk of radiation exposure, it can be overcome with a bone marrow transplant, whereas gastrointestinal damage can be just as deadly and cannot be effectively treated. Now, Taniguchi and co-authors describe a new drug that can protect the intestine of mice from the damaging effects of radiation, even when given up to 24 hours after a radioactive exposure.
