Experiments in zebrafish reveal a new role for a critical hypothalamic transcription factor, orthopedia, in controlling developmental neuropeptide balance in a discrete oxytocin-producing neuronal circuit whose disrupted development affects social behavior.

A mimetic complex composed of at least 140 species of ants, wasps, spiders, true bugs and treehoppers, all with conspicuous golden bodies, has been discovered.
Multicellular and socially aggregating prokaryotes contain previously undescribed, chaperone-based systems predicted to mediate defensive biological conflicts, several components of which are thematically similar antecedents of eukaryotic apoptosis pathways.

Demonstrating extreme diversity across crustaceans while contrasting with evolutionary stability in insects, mushroom body homologues further underpin the unity of Pancrustacea and shed new light on arthropod brain evolution.

A synthetic, prospective article considers how the fields of sensory ecology and collective behaviour can combine when considering animal collective movements and interactions, and how these fields can inspire each other to advance understanding of animal behaviour, adaptation and evolution.
Oxytocin, but not the structurally similar vasopressin, modulates both the chemosensory decoding of femininity in straight men and that of masculinity in gay men in an inverted-U-shaped manner.
