Interplay of mechanics, growth and viral infection dynamics in a spatially expanding bacterial colony

The paper studies how mechanical forces, bacterial growth, and viral infection dynamics interact during the expansion of an E. coli colony, revealing phage hitchhiking and anisotropic spread.

Active geometrodynamics predicts the emergence of cytokinesis

The paper uses a theory of active geometrodynamics and C. elegans zygote data to show that cytokinesis emerges from self-organized patterns of myosin concentration and cell shape.
