The earliest fossil evidence of a mimetic relationship between the Jurassic moth lacewing Lichenipolystoechotes and its co-occurring fossil lichen Daohugouthallus predates modern lichen-insect associations by 165 million years.

Population genetics in turquoise killifish wild populations reveals how small population size and genetic drift determine the accumulation of deleterious gene variants leading to short lifespan.
GABA-A receptors on dopamine neuron axons not only depolarize the membrane but also limit action potential propagation, an effect potentiated by positive allosteric modulators of GABA-A receptors like diazepam (Valium).
KATANIN1 in stigma papilla cells prevents disordered pollen tube growth and straightens pollen tube direction, allowing the pollen tube to find its correct path to the underlying female tissues.

Human vitamin K epoxide reductase (VKOR) has a four transmembrane domain topology that supports the use of a homology model, enabling identification of active site residues and human variant impact.
Bonobo groups that share overlapping ranging areas and engage in regular social exchange show "behavioural group identity" of hunting techniques in the absence of local ecological variation.
Amphetamine reduces reward signaling by neurons in rat prefrontal cortex, but increases the stability of population dynamics, which account for animals’ increased task engagement, despite reduced reward motivation.

Instant performance recovery is possible following general anesthesia-induced unconsciousness using antagonist, and the brain dynamics return abruptly to the awake state without intermediate recovery states.
