   Surface-to-volume scaling and aspect ratio preservation in rod-shaped bacteria

   Nikola Ojkic et al.

   Rod-shaped bacteria preserve their aspect ratios and surface-to-volume scaling by maintaining a homeostatic balance between the rates of cell elongation and division protein synthesis.

   Pressure-driven release of viral genome into a host nucleus is a mechanism leading to herpes infection

   Alberto Brandariz-Nuñez et al.

   Internal DNA pressure of tens of atmospheres inside a herpesvirus capsid powers ejection of the viral genome into a cell nucleus, causing infection.

   Cell-sized confinement controls generation and stability of a protein wave for spatiotemporal regulation in cells

   Shunshi Kohyama et al.

   A cell-sized fully confined space significantly controls the emergence and stability of a protein wave, resulting in intracellular spatiotemporal regulation driven by a reaction-diffusion mechanism.

   Metabolic constraints drive self-organization of specialized cell groups

   Sriram Varahan et al.

   In a developing yeast colony, cells go from homogeneous states to spatially organized, specialized metabolic states, and the new metabolic states depend on resources produced by the original state.

   Swimming eukaryotic microorganisms exhibit a universal speed distribution

   Maciej Lisicki et al.

   Analysis of published studies reveals that flagellates and ciliates separately exhibit log-normal distributions of swimming speeds, and rescaling by the mean speed of each collapses them to a universal relationship.

    A microfluidic device for inferring metabolic landscapes in yeast monolayer colonies

    Zoran S Marinkovic et al.

    Metabolic gradients underlie gene expression patterns within spatially controlled expanding 2D microbial colonies.
