  The manuscript concerns a fundamental and controversial question in Trypanosoma brucei biology and the parasite life cycle, providing further evidence that slender bloodstream forms can indeed infect Tsetse flies. The study is solid in design and execution, and addresses several criticisms made of the authors' earlier work. Nevertheless, some of the main conclusions are only partially supported: one issue is how, precisely, a "slender" bloodstream form is defined, and discrepancies with some results from other laboratories remain unexplained.

  This valuable study uses single-molecule imaging to characterize factors controlling the localization, mobility, and function of RNase E in E. coli, a key bacterial ribonuclease central to mRNA catabolism. The supporting evidence for the differential roles of RNAse E's membrane targeting sequence (MTS) and the C-terminal domain (CTD) to RNAse E's diffusion and membrane association is convincing. It provides insight into how RNAse E shapes the spatiotemporal organization of RNA processing in bacterial cells. This interdisciplinary work will be of interest to cell biologists, microbiologists, biochemists, and biophysicists.

  This study provides important insights into bacterial genome evolution by analyzing single-cell genome sequences of cyanobacteria from Yellowstone hot springs. Using compelling evidence, the authors demonstrate that both homologous recombination within species and frequent hybridization across species are major drivers of genome diversification. Despite the challenges that are inherent to sparse and fragmented single-cell data, the analyses are thorough, carefully controlled, and supported by multiple complementary approaches, making the conclusions highly robust. This work represents a significant advance in our understanding of microbial evolution in natural environments.

  This work provides high-precision single-cell data on the relationship between DnaA activity and cell size, offering important insights for the field of cell cycle control. These findings motivate a novel and intriguing hypothesis for DNA replication initiation -the "extrusion model"- in which DNA-binding proteins modulate free DnaA availability in response to biomass-DNA imbalance. While the current indirect evidence does not fully establish the model, an experimental perturbation involving H-NS offers convincing support for its plausibility, laying the groundwork for future investigation.
