Cell culture-based profiling across mammals reveals DNA repair and metabolism as determinants of species longevity.

abstract：:Animals exhibit innate behaviours to a variety of sensory stimuli including olfactory cues. In Drosophila, one higher olfactory centre, the lateral horn (LH), is implicated in innate behaviour. However, our structural and functional understanding of the LH is scant, in large part due to a lack of sparse neurogenetic t...
