The protozoan parasite Trypanosoma brucei gambiense has undergone recent clonal evolution that reveals the theoretically predicted Meselson effect at a genome-wide level.

An investigation of transposable element evolution in a group of long-term asexual animals shows that many of the predicted effects of asexuality are not observed.

Sexual reproduction is responsible for the evolutionary success of selfish transposable elements.

Arbuscular mycorrhizal fungi generate nuclear diversity in the dikaryotic life-stage stage via inter-nucleus recombination.

A better understanding of the remarkable diversity, natural history and complex ecology of E. coli in the wild could shed new light on its biology and role in disease, and further expand its many uses as a model organism.

Meiotic chromosome segregation in mature Drosophila oocytes is sensitive to prolonged quiescence, suggesting that human oocyte instability may result from storage of mature rather than primordial oocytes and be modifiable.

The ability of transposable elements to epigenetically influence adjacent genes impacts genome evolution by driving substantial variation in transposon numbers between species.

Genome-wide analysis of sister chromatid exchange using single-cell sequencing reveals that most spontaneous sister chromatid exchange events are not due to the repair of double-strand DNA breaks in wild-type yeast cells.

Biochemical analysis in Xenopus egg extracts reveals that the MutSα mismatch sensor retains the DNA-bound replication clamp to maintain a post-replicative temporal window permissive to strand-specific repair of mismatches.
