Self-organization keeps schools of fish, flocks of birds and colonies of termites in sync. It`s also, according to new research, the way cells regulate the final stage of cell division. Scientists at Rockefeller University have shown that a protein-chemistry-based contour map, which helps individual proteins locate the center of their cell without direction from a “master organizer,” is key to ensuring accurate division during mitosis.
