ONLINE COVER Tumors, Take Your Mark…Get Set…Glow! Tiny tumors light up in the mesentery of the peritoneal cavity—a location where ovarian cancers typically relocate in a process called metastasis. In this issue of Science Translational Medicine, Urano and colleagues describe an enzyme-activatable fluorescent probe that only glows when it encounters human ovarian cancer cells. Because the probe can be sprayed on a tumor-ridden region, surgeons can use this to illuminate hard-to-see tumors, for more complete removal.  See related Focus by Bouvet and Hoffman.
