SyeA was present in the Buchnera ancestor, is secreted into the host cytoplasm, is homologous to secreted effectors of bacterial pathogens and is essential for Buchnera transmission.

Snow flies (Chionea) are small, wingless insects active on snow even at sub-freezing temperatures. Capek et al. combine comparative genomics with experiments to show that endogenous heat production, e...

Mochizuki reports a plant that lures pollinating flies by imitating the scent of ants injured by predators. This study reveals the first known case of ant mimicry in flowers and uncovers previously un...

The Drosophila Genetic Database, FlyBase, is on the brink of collapse due to the sudden termination of the FlyBase NIH grant, which includes salaries for 5 literature curators based at the University ...

Dürr et al. develop advanced genetic tools in the host specialist D. sechellia to study its olfactory system neuroanatomy. They show via single-cell labeling, tracing, and quantitative comparison of o...

The colossal squid is the largest invertebrate on the planet, but it is also surprisingly elusive. An image of a 30-centimetre-long juvenile is our first glimpse of the animal in its natural habitat

A connectome of the right optic lobe from a male fruitfly is presented together with an extensive collection of genetic drivers matched to a comprehensive neuron-type catalogue.

A study using flies of the genus Drosophila adapted to life in diverse thermal environments shows how evolution has shaped temperature preference by acting on both molecular heat receptors and th...
