Locomotion and transport of microorganisms in fluids is an essential aspect of life. Search
for food, orientation toward light, spreading of off-spring, and the formation of colonies are …

Bacterial swarming is a collective mode of motion in which cells migrate rapidly over
surfaces, forming dynamic patterns of whirls and jets. This review presents a physical point …

Bacteria commonly live attached to surfaces in dense collectives containing billions of cells.
While it is known that motility allows these groups to expand en masse into new territory …

Twitching motility-mediated biofilm expansion is a complex, multicellular behavior that
enables the active colonization of surfaces by many species of bacteria. In this study we …

Background The biophysical characteristics of cells determine their shape in isolation and
when packed within tissues. Cells can form regular or irregular epithelial structures, round …

Myxococcus xanthus cells self-organize into aligned groups, clusters, at various stages of
their lifecycle. Formation of these clusters is crucial for the complex dynamic multi-cellular …

Myxococcus xanthus is a model organism for studying bacterial social behaviors due to its
ability to form complex multi-cellular structures. Knowledge of M. xanthus surface gliding …

Stem cell maintenance in multilayered shoot apical meristems (SAMs) of plants requires
strict regulation of cell growth and division. Exactly how the complex milieu of chemical and …

An individual-based, mass-spring modeling framework has been developed to investigate
the effect of cell properties on the structure of biofilms and microbial aggregates through …

Cell migration is a fundamental biological phenomenon during which cells sense their
surroundings and respond to different types of signals. In presence of durotaxis, cells …
