     The work is interesting in its characterization of a large number of antibiotic persisters from a wild-type strain. Previous work was typically limited to directly observe either high persister strains or a smaller number of wt persisters. Therefore, it sheds new light on the elusive non-dormant persisters present in exponentially growing cultures and should help resolve previous conflicting observations.

     This important study shows that the Nora virus, a natural Drosophila pathogen that also persistently infects many laboratory fly stocks, infects intestinal stem cells (ISCs), leading to a shorter life span and increased sensitivity to intestinal infection with the Pseudomonas bacterium. The authors provide convincing data to support their conclusions. The paper provides new insights into virus-host interactions in the Drosophila gut and serves as a warning for scientists who use the fruit fly as a model to study gut physiology.

     This important research addresses the effects of subjective control and task difficulty on experienced stress using a novel behavioral task in two, large online samples. Convincing evidence is provided, establishing internal and external task validity and a relationship with individual differences in relevant mental health constructs. Evidence for the core claims could be strengthened by disentangling the effects of controllability from those of reward rate and adjusting data parcellation for computing internal consistency. This work will be of interest to psychologists and clinicians studying controllability, stress, and psychopathology.

     The manuscript provides valuable findings in the field for understanding the RNAi regulation in plants at the molecular level with a model of how DRB7.2 and DRB4 form a heterodimer and protect dsRNA from DICER activity. The presented data provide a solid basis for the model, but certain measurements could benefit from replicates for robust statistics.

     In this manuscript, Franco and colleagues describe valuable findings about the chemotactic response of Salmonella to serine and indole, conflicting chemotactic signals. Although the evidence presented is solid, concerns were raised about the novelty of the chemotactic phenomena observed with these two compounds. Also, although the induction of invasion by feces is a novel and interesting finding, the lack of follow-up to this observation was also noted.

6. C-terminal tagging, transmembrane domain hydrophobicity, and an ER retention motif influence the secretory trafficking of the inner nuclear membrane protein emerin

     This solid work, a Research Advance linked to Buchwalter et al., 2019, demonstrates that epitope tagging influences protein fate, serving as a cautionary example of how different tagging and imaging strategies may alter the pattern of endogenous protein trafficking. The information presented will be useful for researchers in the field of membrane trafficking, particularly in guiding their experimental designs. That being said, the study offers limited new insights into the biogenesis or disposal of endogenous Emerin.

     This potentially important model-based study seeks to mimic bat echolocation behavior and flight under high-density conditions. The simulations convincingly suggest that the problem of acoustic jamming in these situations may be less severe than previously thought, a finding that would be of broad interest to scientists working in the fields of bat biology and collective behaviour. However, some aspects of the manuscript were found to lack clarity and concerns were raised about some of the assumptions underlying the parameters used for the simulations, which impact both the modeling results and the conclusions that can be made from the data.

     The authors propose that the kinase MARK2 regulates the Golgi's reorientation towards the cell's leading edge through the regulation of microtubule binding protein CAMSAP2 and its binding to USO1. While the model is interesting and the study is useful, the quantification of an insufficient number of cells and insufficient description of the methods and biological replicates mean the results are inadequate to support the model.

     This study provides compelling evidence that kinesin's stepping mechanism is governed by strain-induced conformational changes in its nucleotide-binding pockets. Using pre-steady state kinetics and single-molecule assays, the authors demonstrate that the neck linker's conformation differentially modulates nucleotide affinity and detachment rates, establishing an asynchronous chemo-mechanical cycle that prevents simultaneous detachment. Supported by cryo-EM structural data, the work presents an important advance in our understanding of kinesin's hand-over-hand movement.
