     This auhors present findings on the role of the sirtuins SIRT1 and SIRT3 during Salmonella Typhimurium infection. This valuable study increases our understanding of the mechanisms used by this pathogen to interact with its host and may have implications for other intracellular pathogens. The reviewers disagreed on the strength of the evidence to support the claims. Although one reviewer found the strength of the evidence convincing, the other found that it was incomplete, and that the main claims are only partially supported, as can be seen from the public reviews.

     This study provides valuable observations indicating that human pyramidal neurons propagate information as fast as rat pyramidal neurons despite their larger size. Convincing evidence demonstrates that this property is due to several biophysical properties of human neurons. This study will be of interest to neurophysiologists.

     This valuable study demonstrates that the behavior of the cells in the presomitic mesoderm in zebrafish embryos depend on both an intrinsic program and external information, providing new insight into the biology underlying embryo axis segmentation. There is convincing support for the findings with a thorough and quantitative single-cell real-time imaging approach, both in vitro and in vivo, developed by the authors.

     The authors observed a positive correlation between FSH and fat mass, as well as a negative association with the appendicular lean mass/fat mass ratio. These valuable findings in male subjects within a hypogonadal setting following Degarelix treatment imply that FSH might function as a predictor, similar to observations in women. However, it's important to note that the analysis is incomplete, as other major confounding factors such as testosterone were not included.

     This landmark study presents MetaPathPredict, a method that uses a stacked ensemble of neural networks to predict the presence or absence of KEGG modules based on annotated features in the genome. The evidence supporting the conclusions is compelling, with a tool that allows for prediction of KEGG modules in sparse gene sequence datasets.

     Using single-cell sequencing, high-resolution imaging, and inducible genetic deletion of yolk-sac (YS) derived macrophages, the authors present a useful map of fetal liver macrophage subpopulations and provide important data demonstrating that heterogeneous fetal liver macrophages regulate erythrocyte enucleation, interact physically with fetal HSCs, and may regulate neutrophil accumulation in the fetal liver. These novel findings, although yet incomplete, might provide a solid foundation for further investigating the effects of macrophages on HSC function during fetal hematopoiesis and into adulthood and will be useful for the field of macrophage biology and developmental hematopoiesis.

     The findings are important and would potentially have theoretical and practical implications outside the field. However the strength of evidence presented was assessed as being incomplete in several respects. Major strengths are (1) genetic factors in facial appearance are of broad interest, and the potential influence of possibly identical factors in a serious congenital disorder (cleft lip/palate) heightens that interest further; (2) proving which single nucleotide variants influence phenotypes, and by what mechanisms, is a major challenge for the field as a whole. The weakness, as assessed, was that in its present form the experimental approach was not sufficiently rigorous to support the conclusions unambiguously.

     This important study presents data suggesting that HFD-induced histone epimutations in sperm may impact the transcriptome of the placenta, thereby contributing to the paternal transmission of paternal metabolic disorders to offspring. Although the hypothesis is interesting and the evidence presented is compelling, more careful statistical analyses and functional validation experiments are needed to further strengthen the conclusion.

     In this important study, the authors explore the importance of developmental changes in cortico-DRN innervation in the balance of behavioral control in a foraging task. The authors report somewhat convincing evidence that while juvenile mice and adult mice both perform the task, juveniles exhibit more impulsive behavior due to reduced efficacy of cortico-DRN projections. The authors conclude that the development of cortico-DRN (esp mPFC) projections allows 5HT input to promote perseveration (or exploitation) in the balance of behavioral control. However, reviewers raised issues regarding the strength of the evidence without further experiments.

      This manuscript addresses a non-canonical function of the Class 2 ribonuclease III Drosha in the regulation of adult neural stem cell fate, important for understanding how these cells generate neurons or oligodendrocytic cells.
      Overall, this manuscript has many strengths. The authors identify 165 proteins, several of them enriched in neural stem cells, and potentially specific for miRNA dependent or independent Drosha macromolecular complexes.
      While the authors provide systematic and convincing evidence on the biochemical interactions among the key players in this cascade, the significance of these interactions for neural stem cell fate determination in vivo remains unclear, as the in vitro cellular systems used to document most of the data reported in the paper may not (fully) represent resident neural stem cells in the adult hippocampus. The in vivo function mediated by Drosha/ Safb1 needs to be substantiated by more evidence and/or complementary approaches.
