The sense of smell of female hawkmoths has evolved to find the intense odor of floral nectar sources as well as inconspicuous scents of oviposition sites within a complex olfactory landscape.

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.

The mushroom body neuropils of the larval brain have regions that share neurons and functions with the adult and larval-specific regions built with 'doomed' neurons or cells that trans-differentiate for temporary larval function before assuming their adult phenotypes at metamorphosis.

A screen of lactic acid bacteria reveals that diet modulates the age-dependent decline of thermotaxis behavior in C. elegans without changing the organismal lifespan.

The Drosophila lateral horn, a higher olfactory brain area, contains >165 genetically defined cell types with stereotyped odour responses across animals and improved odor categorisation compared with their inputs.

A previously unrecognized group of metalloenzymes enables human gut microbes to metabolize dietary molecules and neurotransmitters and likely mediates interactions and metabolism among environmental microorganisms.

Motor neurons controlling the leg of the fruit fly exhibit a gradient of physiological and functional properties that correlate with the order in which they fire during behavior.

A transcriptome-based metric for aging reveals a longevity mechanism that specifically prolongs the duration of young adulthood rather than slowing overall aging.

A discrete group of interconnected neurons are shown to drive aggressive social interactions in Drosophila females and genetic tools to manipulate these neuronal cell types are provided.
