High-resolution simulations of evolving microbial populations reveal that microscopic epistasis slows the rate of adaptation, while clonal interference can either speed it up or leave it fixed.
When crowded bacterial colonies invade a closed area, flow-induced alignment creates strong radial orientation and leads to the formation of aster defects.

Light-seeking strategies in Zebrafish larvae are dissected using a virtual-reality assay, and these data are used to establish minimal stochastic and neural-circuits models that quantitatively capture this behavior.

A simple efficient coding model predicts complex trade-offs in resource allocation for sensory inputs with heterogeneous receptor densities and activation levels.

The combination of data and modelling shows the mechanisms underlying bidirectional flow of cerebrospinal fluid and its impact on long range transport in the CSF between brain and spinal cord.

A quantitative analysis of glucose-dependent transport regulation indicates that mitochondrial accumulation in regions of high nutrient availability can enhance metabolism in neuronal axons under physiologically relevant conditions.
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.
