Actively regulated immune memory differentiation, with a preference for cross-reactive receptors with moderate affinity against pathogens as opposed to high-affinity receptors, confers a long-term benefit to the host.
Minimal essential features of Rho GTPase systems are elucidated that regulate the number of distinct domains developed by a cell’s polarity machinery, which in turn governs cell shape.
For the same bacterial strain, the swarming phenotype can be biophysically discerned from swimming phenotype based on the motion pattern under circular confinement on a soft agar.

The 'spinning lasso' geometry of Euglena's beating flagellum is revealed, and a model based on the antagonistic forces exchanged by axoneme and paraflagellar rod is proposed to explain its emergence.

The amphipathic helix of perilipin 4 relies on the organization of its polar residues to form a remarkably immobile and stable protein layer on the surface of lipid droplets.

Noisy circadian clocks in Anabaena, coupled by cell-cell communication, display high spatio-temporal coherence and can be robustly described by incorporating demographic noise in a theoretical model of coupled clock arrays.

Theoretical predictions and experiments on multicellular aggregates indicate that the extracellular matrix acts as a mechanical sensor, which regulates cell proliferation and migration in a three-dimensional environment.
