  • Bacteria move along gradients of chemical attractants. Two studies find that, in nutrient-rich environments, bacteria can grow rapidly by following a non-nutritious attractant — but expanding too fast leaves them vulnerable.

  • In living systems, chemical reactions and the geometry of cells feed back on each other. Methods for computational modeling are beginning to take this complexity into account.

  • Odour motion contains valuable directional information that is absent from the airflow alone, and Drosophila use this directional information to shape their navigational decisions.

  • Information theory sets an upper limit on the ability of bacteria to navigate up chemical gradients. Experiments reveal that cells do so at speeds within a factor of two of the limit, suggesting they are selected to efficiently use information.

  • How bacteria migrate collectively despite individual phenotypic variation is not understood. Here, the authors show that cells spontaneously sort themselves within moving bands such that variations in individual tumble bias, a determinant of gradient climbing speed, are compensated by the local gradient steepness experienced by individuals.

  • In bacteria, the lack of compartmentalization within membrane-enclosed compartments has made it difficult to determine how mature messenger RNAs are spatially distributed. Here the authors use fluorescence experiments in bacteria to follow mRNA dispersal after transcription. They find, surprisingly, that the newly transcribed mRNAs show limited diffusion, and speculate that the packed chromosomal material may itself act as a partition to separate translation from mRNA degradation.

  • In his study of Brownian motion, Einstein realized that the same random molecular movements characterizing a substance at rest should affect, for example, the drag it opposes to a particle pushed through it. This was later generalized as the fluctuation–response theorem (FRT), but whether and how it may apply to biological systems, which operate far from equilibrium, has remained an open question. Based on the unmatched fine-scale measurements possible in the study of bacterial chemotaxis, it is now revealed that the FRT does apply in this case, and ways to dissect which features in the biochemical network couple its internal states with its responses to external stimuli are suggested.
