The socially exchanged fluid passed mouth-to-mouth during trophallaxis contains molecules that can influence development, potentially mediating communal control of colony phenotypes.

Genes associated with age-based division of labor in ants exist in distinct regulatory and evolutionary contexts; genes up-regulated in young nurses are loosely connected and rapidly evolving while genes up-regulated in old foragers are highly connected and conserved.

During initiation factor-independent RNA structure-driven translation initiation, a flexible RNA element drives the movement of a viral IRES through the ribosome's tRNA binding sites and promotes tRNA binding.

Tapeworms grow and regenerate using stem cells distributed throughout their bodies, but their regeneration competence relies upon the unique micro-environment created by the head and neck.

Triacylglycerides found in the males of 11 species of Drosophila form a largely overlooked, novel, sex-specific class of pheromones that act to suppress courtship behaviour.

A Internal Ribosomal Entry Site RNA has been visualised by high resolution cryoEM, trapped in the ribosome in an intermediate state of translocation.
