     Evaluation Summary:

     This paper is of outstanding interest to the broad community of scientists interested in biological energy conversion in general and rotary ATPases in particular. The authors show that the 36{degree sign} power stroke in ATP synthesis is subdivided into two steps of 11{degree sign} and 25{degree sign} in the E. coli enzyme, which serves as a comparatively simple model of the fundamental and universally important process of ATP production in mitochondria and chloroplasts. By combining precise and sophisticated single-molecule studies with directed mutagenesis, this work provides the much-needed functional context for recent high-resolution cryo-EM structures of rotary ATPases.

     Evaluation Summary:

     This paper is of interest not only for immunologists studying the inflammation, but also for biomedical researchers studying various biological processes using C57BL/6 mice. The data in this paper indicate that genetic differences between C57BL/6 substrains can affect reproducibility and generalizability in a broad range of biological studies with mouse models reported to date.

     Evaluation Summary:

     This work identifies the primary genetic mechanism underlying UV-absorbance variation across the geographic range of sunflower (Helianthus annuus) and provides evidence that suggests that abiotic variables, rather than pollinators, may maintain this variation in H. annuus and perhaps Helianthus broadly. While claims about direct links to fitness in natural population remain untested, the authors synthesize an ambitious amount of work from an impressive breadth of methods (from transgenics to ecology) that will be of high interest to ecologists and evolutionary biologists.

4. Respiration aligns perception with neural excitability

     Evaluation Summary:

     Kluger and colleagues investigated the influence of respiration on visual sensory perception in a near-threshold task and argue that the detected correlation between respiration phase and detection precision is liked to alpha power, which in turn is modulated by the phase of respiration. The main finding - that the moment-to-moment relationship between excitability and perception is coupled to the body's slower respiratory oscillation - poses a potentially important advance for advancing our understanding of how the brain-body system works as a whole.

     Evaluation Summary:

     Campylobacter jejuni is serious food-borne pathogen and understanding how the various products necessary for pathogenesis are regulated is a key step in preventing its growth and/or treating disease. Here, Sharma and coworkers describe the complex pathway that leads to the maturation of two complementary regulatory RNAs and how one of the RNAs antagonizes the other to relieve repression of a virulence-related gene.

     Evaluation Summary:

     In this study, the authors develop a model to understand the simplest form of collective migration represented by a pair of cardiopharyngeal progenitor cells. They propose that the collective migrates as a "supracell", with leader cells assuming a greater protrusive capability and trailer cells assuming greater retractive capability. They meticulously study the effects of leader-trailer and cell-matrix adhesivity, intracellular force distributions and noise on robustness of cell migration. They corroborate their simulation results with experiments. Overall, this study comprehensively demonstrates that migrating as a collective leads to more mechanically efficient and persistent migration than as a single motile cell.

     Evaluation Summary:

     This manuscript by Jayaram and colleagues uses computational modeling approaches to examine how temporal filtering of an odor signal contributes to navigation success in different odor environments. The manuscript advances the literature in considering how different algorithms may be optimal for different environments. Further evidence is required to more convincingly prove the intriguing trade-off between frequency and "intermittency" sensing described here.

     Evaluation Summary:

     Mejias and Wang propose here the first large-scale model of the brain that actually performs a cognitive task. Previous models have focused on neural dynamics during the so-called "resting state", in which subjects are not performing any cognitive task - thus, resting. This study is therefore an important improvement in the field of large-scale modelling and will certainly become an influential reference for future modelling efforts.

      The paper is of interest to RNA biologists, especially to those who study small RNAs. The findings deepen our understanding of the rules of DCL3 dicing and explain how 23-nt and 24-nt siRNAs in the RNA-directed DNA methylation pathway are produced. Overall, the data are of high quality and support the paper's conclusions.
