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

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

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

Cascades of transient pairwise interactions, stabilized by multisensory inputs, drive the formation of a well-organized social structure from a group of loosely distributed flies.

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

Collective responses of animals are generally controlled by complex biological mechanisms and in Caenorhabditis eleganscollective dynamics are purely controlled by physical parameters such as oxygen penetration and bacterial diffusion.

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.

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.
