Tissue-specific temporal regulators impinge on the VEGF/Delta-Notch pathway to vary tip cell selection pace yielding diverse densities of vascular network.

Migrating skin carries the amphid rosette vertex anteriorly to extrude and position dendrites.

Two seemingly distinct behaviors in social C. elegans worms, namely aggregating into groups and swarming over food, are driven by the same underlying mechanisms.

Behavioral experiments reveal that ants, contrary to humans, avoid the formation of traffic jams at extreme density.

A computational model shows that natural selection can cause populations to evolve a distinctive population-level phenotype: the ability to transition between collective states in response to the environment.

The socially exchanged fluid passed mouth-to-mouth during trophallaxis contains molecules that can influence development, potentially mediating communal control of colony phenotypes.

For baboons on the move, habitat features across multiple spatial scales combine with social interactions to impact the movements of individuals, ultimately shaping the structure of the whole group.

Cell movement toward and away from the midline of an epithelium over tens of hours are caused by spontaneous or externally-applied shear forces to eliminate force imbalances within the tissue.

Shorebird flocks fly in a formation that re-creates the neighbor positioning relationship of a V-formation in cluster flocks of more than 1000 birds.
