Protracted neuronal maturation in a long-lived, highly social rodent.

Naked mole-rats are a long-lived rodent species (current lifespan >37 years) and an increasingly popular biomedical model. Naked mole-rats exhibit neuroplasticity across their long lifespan. Previous studies have begun to investigate their neurogenic patterns.

A death pheromone, oleic acid, triggers hygienic behavior in honey bees (Apis mellifera L.).

Eusocial insects live in teeming societies with thousands of their kin. In this crowded environment, workers combat disease by removing or burying their dead or diseased nestmates. For honey bees, we found that hygienic brood-removal behavior is triggered by two odorants - β-ocimene and oleic acid - which are released from brood upon freeze-killing.

Odorant cues linked to social immunity induce lateralized antenna stimulation in honey bees (Apis mellifera L.).

Hygienic behaviour (HB) is a social immunity trait in honey bees (Apis mellifera L.) whereby workers detect, uncap and remove unhealthy brood, improving disease resistance in the colony. This is clearly economically valuable; however, the molecular mechanism behind it is not well understood.
