Experimental results in Drosophila support a model in which gene expression is fundamentally controlled by morphogens tuning the same transcription parameter for genes that are expressed in highly diverse patterns.
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.
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.
Horizontal gene transfer (HGT) helps slightly beneficial genes persist in microbial populations, incentivising cells to invest in costly DNA uptake, even in the presence of harmful selfish genetic elements.
Customization of ion channel gating enhances homeostatic regulation through automatic detection and correction of abnormal physiological changes, as illustrated by self-restoration of excitation rhythm in cardiac arrhythmias.
