TL;DR: A single-cell atlas of the adult fly, Tabula Drosophilae, that includes 580,000 nuclei from 15 individually dissected sexed tissues as well as the entire head and body, annotated to >250 distinct cell types is presented, providing an in-depth analysis of cell type–related gene signatures and transcription factor markers, as as sexual dimorphism, across the whole animal.

TL;DR: It is shown that ssm is a point mutation in the Hira gene, thus demonstrating that the histone chaperone protein HIRA is required for nucleosome assembly during sperm nucleus decondensation, and that nucleosomes containing H3.3, and not H3, are specifically assembled in paternal Drosophila chromatin before the first round of DNA replication.

TL;DR: It is suggested that a threshold level of infection is required for normal expression of CI and that host factors help determine the density of the symbiont in the host.

TL;DR: It is reported that an undescribed bacterium is vertically transmitted and associated with thelytokous parthenogenetic reproduction in Encarsia, a genus of parasitoid wasps and suggested that EB may modify the behavior of its wasp carrier in a way that enhances its transmission.
