When real ants confront the classical 'Ant-in-a-labyrinth' physics problem where a random walker traverses a percolated environment, they employ active extended sensing and collective cognition to outperform passive physical solutions.
In stau-mutants, the Hunchback boundary shifts posteriorly by 10% EL but shows comparable variability to that of the wild type in short time windows in nuclear cycle 14.
Four species of seabird produce efficient propulsive wakes while flying in the air and while swimming underwater suggesting that selection has optimized these species for locomotion in remarkably different fluids.

An adenylyl cyclase isoform is shown to dynamically traffic to endosomes after activation by G protein in mammalian cells, contributing to cellular cAMP signaling by internalized GPCRs.
Computational models demonstrate that circuit resilience to temperature perturbations are associated with smooth transitions between cellular mechanisms as the contributions of different currents are altered while activity is maintained.

The global sleep homeostatic process tracks sleep-wake history by integrating local cortical neuronal activity over time and space, rather than directly reflecting changes in specific homeostatically regulated physiological variables.
