     Evaluation Summary:

     This paper is of potential interest to a broad audience of neuroscientists. By concluding that fear conditioning does not occur in a semi-naturalistic experimental setup, the study implies a major adjustment in our current understanding of Pavlovian fear conditioning and associative learning. However, additional controls and data analyses are required to validate the authors' conclusions.

     Evaluation Summary:

     In this paper the authors study the Rolle of small chain fatty acids receptors FFA2 and FFA3 in the dorsal root ganglia with the goal to define molecularly a gut to brain axis. They identified MOMBA as a compound that binds to FFA2. This paper presents a powerful screening strategy to identify receptor agonists. The main concerns are the specificity of the model, and the functional purpose of this gut to brain axis.

     Evaluation Summary:

     This work develops a multistage/component mathematical model to analyze advanced colorectal adenomas and the impact that aspirin therapy has on adenoma formation rates. This study will be interesting to the cancer evolution community and in particular those interested in colorectal cancer incidence. While the model is mainly focused on aspirin chemoprevention, the model could be adapted to test other putative preventative agents, and thus could have a broad impact.

     Evaluation Summary:

     This paper presents groundbreaking data on the effects of antimicrobial peptides on bacterial cells, obtained by time resolved small angle X-ray and neutron scattering experiments coupled to stopped-flow mixing. Application of this approach to cells is highly innovative and provides ms time resolution, and information on multiple length scales (from conformational changes in the cell, to structural changes in the membranes). This is an important extension of the effort of the scientific community to study model membranes. The main result is that the peptides reach the cytosol in a few seconds, accumulating to high concentrations. The data analysis should be improved, and many conclusions are speculative, in particular on the mechanism of entry of the peptides.

     This manuscript will be of interest to community ecologists working on the impact of predators on prey populations, as well as disease ecologists interested in understanding the potential role of predators on vector traits. The authors uncovered trends in the research that support beneficial impacts of predators on mosquito traits, from the standpoint of vector control.

     Evaluation Summary:

     This paper uses a powerful combination of imaging techniques to provide a thorough view of the structure of the gap junction network connecting rod and cone photoreceptors in the mouse retina. The main conclusion - that rod-cone coupling is much more prevalent than rod-rod or cone-cone coupling - is well supported by the data although some results require qualification. The main concern in review centers around the importance of this result beyond the retina community.

     Evaluation Summary:

     The authors of this study investigate the consequences of acute or chronic disruption of parts of the TCA cycle, and how different interventions can drive different transcriptional responses. Specifically, the authors use both pharmacological and genetic methods to disrupt succinate dehydrogenase or fumarate hydratase, and characterize the effect of each on metabolism. They also find that disruption of these enzymes elicits a transcriptional response through ATF4. This work provides insight into how metabolism is affected by TCA cycle loss, and how how this affects metabolic stress signaling.

     Evaluation Summary:

     This manuscript features high quality experimental data with a detailed and clear analysis, combined with a neural network model to address the concept of differentiation in cerebellar functioning. This is an intensively debated topic currently and this work has an important, clear message to add to that debate. The data is very exciting, and the analyses and computational modeling very revealing and insightful. This stands on its own as a major contribution. The authors also raise an extremely interesting mechanistic interpretation of these data, which is tantalising but requires further support.

     Evaluation Summary:

     Baker et al. investigates the molecular evolution in primates of one protein family, the CEACAMs, that are a recurrent target of bacterial surface adhesions at epithelial surfaces. They show that multiple members of this gene family have experienced repeated episodes of positive selection in primates, especially in the N-terminal domains that are associated with protein binding and go on to evaluate the functional consequences of these evolutionary changes.

      Evaluation Summary:

      This paper is of interest to scientists within the field of motor learning. Converging evidence from several behavioural experiments support key claims of the paper. However, it is unclear to what degree the reported effects can be strongly linked to motor versus cognitive systems, and to what degree they novel demand revision of existing theoretical frameworks.
