A sexually dimorphic circuit node controls a persistent, internal state that promotes fighting and mating in Drosophila, revealing parallels with mammalian systems suggestive of a conserved circuit "motif" controlling social behaviors.

A genetic pathway involved in development works together with the sex-determination pathway to control the timing of sexually dimorphic neural development in C. elegans.

The balance between sleep and sex drives determines whether male flies sleep or court, and a subset of octopaminergic neurons interact with the Fruitless-expressing courtship circuit to suppress sleep for sustained courtship.

The relentless expansion that threatens the sustainability of biomedical research in the US takes a heavy toll on young researchers.

A better understanding of the mechanisms underpinning the growth of mycobacteria could help identify targets for new antibiotics.

Gaining genetic control over neural modules that drive the grooming of each Drosophila body part reveals how mechanisms for selecting among competing behavioral choices are used to generate sequences of actions.

The cellular and molecular substrates that underlie the programmed behavioral response to a gustatory sex pheromone have been identified.

The timing of sexual differentiation in the brain of the nematode Caenorhabditis elegans is controlled by a phylogenetically conserved pathway of gene regulatory factors.

The generation and systematic characterisation of driver lines labelling a large number of neurons in the Drosophila innate olfactory processing centre bridges electron microscopy neuronal reconstructions, circuits and behaviour.
