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

Epithelial cells utilize a covering sheath of motile cells to migrate in confinement.

A coordinated tissue movement during C. elegans central nervous system internalization reveals a novel role for HMR-1/cadherin in maintaining cohesion, and extends the concept of neurulation beyond vertebrates.

Xenopus embryos use tissue surface tension to generate hoop-stress around the blastopore to help close it during gastrulation.

The temporal patterns of MAPK activity differentially regulate cell autonomous and non-cell autonomous effects of oncogene expression.

Analysis of axial polarity distributions shows that Wnt5a regulates collective cell migration in vivo by stabilizing vinculin at adherens junctions and fine-tuning mechanocoupling between neighbouring cells.

A computational model, based on single-cell features like contractility and polarizability, quantitatively describes cellular dynamics from the single cell level up to small cohorts and confluent tissues.

Very local molecular patterns impart precise changes in the local mechanics of individual cell-cell junctions.

Rather than complex decisions, it is the motion of individuals that allows for collective foraging regulation in ant colonies.

Fish schools showed an U-shaped metabolism-speed curve and reduced the energy use per tail beat up to 56% at high swimming speeds compared to solitary fish.
