One hundred one high-quality drosophilid genomes are released, along with low-cost assembly workflows, as an open community resource for studying genetics, ecology, and evolution in this important model system.

Gene expression timing during Drosophila development is specified by multiple classes of RNA polymerase II core promoters, and the embryonic transcriptome includes thousands of evolutionarily conserved long noncoding RNAs.

Drosophila grooming is driven by two internal programs.

Molecular structure of mitochondrial complex I from Drosophila melanogaster reveals a structural element not seen in other organisms to date that may regulate the transition between an off-pathway resting state and the active state of the complex.

The circadian clock gates sleep drive by modulating sleep homeostat neurons.

Alternative splicing provides a mechanism to maintain oscillations of the circadian clock.

The intestine contains distinct subregions specialized for digestion along its anterior-posterior axis, and the stem cells that constantly renew these subregions are not interchangeable.

Drosophila renal stem cells are exceptional in abundance, require induction to produce a single cell type, principal cells, and mitigate damage during adulthood associated with external stresses.

Profiling of mRNA poly(A)-tail lengths and translational efficiencies provides new insights into posttranscriptional gene regulation in early Drosophila development.

New experiments and theory reveal how the ability to see image details depends upon photoreceptor function and eye movements, and how fruit flies (Drosophila) see spatial details beyond the optical limit of their compound eyes.
