Physiological differentiation during symbiosis leads to division of labor between smaller and larger cells in an uncultured bacterial tubeworm symbiont population and results in remarkable metabolic diversity and complexity.

The ParABS system positions plasmids precisely within the cell but just below the threshold for oscillatory dynamics.

For initiation of cell-wall insertion, the cross-linking enzyme PBP2 stably binds to a component of the cell envelope that is different from MreB filaments.

Diffusion of differently sized proteins in bacterial cytoplasm is nearly Brownian and consistent with the Stokes-Einstein relation, once protein shape and cell geometry are taken into account, and effects of various perturbation can be described as changes in cytoplasmic viscosity.

Klebsiella pneumoniae has specific repertoires of genes required for growth in urine and serum, highlighting new targets for antimicrobial treatments of this important pathogen.

Formation and cell pole-localization of chemotactic signaling-arrays is a coupled process mediated by ParP, which drives localized array-assembly and regulates the localization-dynamics of its network constituents.

Models of chromosome compaction by condensins demonstrate that two-sided loop extrusion and long residence times are required for high compaction, suggesting a tight coupling between these two properties in vivo.

In the PomX/Y/Z cell division regulatory system, PomX is a PomZ ATPase activating protein, a scaffold for PomX/Y/Z complex formation, and important for fission of the PomX/Y/Z complex during division.

Carboxysomes, the carbon-fixation machinery of cyanobacteria, are equidistantly-positioned by dynamic gradients of the protein McdA on the nucleoid that emerge through interaction with a previously unidentified carboxysome factor, McdB.
