The hypoxia-inducible factor HIF drives transcription of the gene cyp-36A1, which encodes a cytochrome P450 enzyme that acts via a putative intercellular signal to regulate the nuclear receptor NHR-46 and consequently stress resistance and behavior.

Comprehensive analyses of how mutations in a picornavirus capsid affect viral fitness provide novel insights into viral biology, evolution, and host interactions.
A technique called mSTARR-seq sheds light on how DNA methylation may shape responses to external stimuli by altering the activity of sequences that control gene expression.

A set of adaptive mutations affect only a small number of phenotypes that matter in the evolution condition, and yet contain substantial latent functional diversity revealed in distant environments.
Single molecule DNA-binding trajectories and deterministic modeling analyses demonstrate a functional role for high energy partly folded states in Transcription Activator-Like Effectors that could improve future TALEN design.

A behavioural paradigm demonstrates that during courtship song preference by female mice relies on the temporal regularity of the male's production of song syllables.
