Meet author Dr. Cocucci: experiments show how cells ‘eat’

A new study shows how cell membranes curve to create the "mouths" that allow the cells to consume things that surround them. The study, published last month in the journal Developmental Cell, found that the intercellular machinery of a cell assembles into a highly curved basket-like structure that eventually grows into a closed cage. Scientists had previously believed that structure began as a flat lattice. Membrane curvature is important, Kural said: It controls the formation of the pockets that carry substances into and out of a cell.
