Across primates, volumes of specific brain regions relate to specific socio-ecological factors, bridging the gap between neuro-cognitive operations from laboratory studies and challenges primates face in their natural environment.

Hypoxic accumulation of squalene, the substrate of squalene monooxygenase, triggers its proteasomal truncation to a constitutively active variant that preserves downstream sterol synthesis.

Located in the legs, the miniaturized katydid ears exhibit cuticular pinnae to only capture high-ultrasonic bat echolocation calls, but katydid also hear their own calls using alternative ear paths, which suggest that their ears operate in a colossal frequency range.

Growth of Arabidopsis seedlings at low temperatures differs between plants that hail from different parts of the world in a way that suggests climate adaptation.

Multimodal signals may evolve from unimodal one via co-option of primary signal components and associated cues that serve as by-products.

Small molecule inhibitors of gut microbial choline trimethylamine lyase activity protect against obesity.

Circadian control of neuronal excitability in the master circadian clock of a diurnal mammal as revealed by whole-cell recording and mathematical modeling.

Being active during the day requires a slow-closing ion channel that dampens the activity of neurons in a specific area of the brain.
