COVER To make mice better mirrors of human cancer, researchers are building "avatars" with the cancer of a particular patient, or engineering mice to spontaneously develop tumors just like people do. The work marks a sea change in cancer biology and is stirring hope that new mouse models will pave the way to more personalized care. See pages 24 and 28.
