  • The authors show microtubule motion along concentration gradients of proteins and salts similar to those found in the cytoplasm. Based on their observations they propose diffusiophoresis as a potential motorless transport mechanism for cytoplasmic particles along intracellular solute gradients.

  • The E. coli MinCDE system oscillates between cell poles to position the main division protein FtsZ. Here authors use in vitro reconstitution to show that MinDE oscillations also regulate unrelated membrane proteins spatiotemporally into patterns and gradients by forming a moving physical barrier.

  • How cell division is regulated with spatiotemporal precision is not fully understood. Here the authors show that a bacterial protein undergoes phase separation through surface-assisted condensation to enrich the tubulin homolog FtsZ in M. xanthus cell division.

  • Protein oscillations linked to cell division in Escherichia coli are shown to localize unrelated molecules on the cell membrane via a diffusiophoretic mechanism, in which an effective friction fosters cargo transport along the fluxes set up by the proteins.
