The activity of Dcp-1, one of Drosophila executioner caspases, is selectively regulated by the autophagy–Bruce axis, which enables distinct non–lethal functions for promoting tissue growth independent of cell death.

Meiotic axis protein deposition and double-strand break formation near yeast chromosome ends are regulated by multiple distinct layers of regulation, including the chromatin modifiers Sir2/3 and Dot1.
Specialized anterior intestinal cells in Caenorhabditis elegans act as sentinels, regulating pathogen responses and linking food availability to gut peptide secretion through pyruvate metabolism.
Carrying 'teaching' signals and modulating movement, two highly conserved functions of the dopaminergic system across all animals, are brought about by the same individual dopaminergic neurons in an insect larva.
Perceptual metamers reveal that the visual system averages luminance over a spatial extent four times smaller than spectral energy, but such estimates depend critically on experimental design choices.

The metabolic pressure exerted by a pathogen with an intracellular lifestyle drives epigenetic modifications, which modulate the transcriptional response of the host to infection.

Juvenile brown trout rapidly respond to fine-scale temperature disturbances, demonstrating behavioral mechanisms that support resilience to sudden thermal disruptions in freshwater ecosystems.
Gluconeogenesis rescues insects from glycogen phosphorylase suppression, establishing metabolic redundancy as a key consideration for insecticide target selection.
