title: The clammy grip of parasitic tumors.
abstract: An epidemic of leukemia among bivalve molluscs is spreading along the Atlantic coast of North America, with a serious population decline of soft-shelled clams. In this issue of Cell, Metzger et al. use forensic DNA markers to demonstrate that the leukemia cells have a clonal origin and appear to be transmitted through sea water.
