      This important study identifies and partially characterises two proteins optimised for coordinated peptidoglycan degradation during two spore morphogenesis programs in the bacterium Myxococcus xanthus. The evidence supporting the conclusions is solid, although the description of the data is somewhat overstated. After some editing, the paper will be of interest to those studying peptidoglycan synthesis and reorganisation, which is a central aspect of microbial cell biology.

      This study is a fundamental advance in the field of developmental biology and transcriptional regulation that demonstrates the use of hPSC-derived organoids to generate reproducible organoids to study the mechanisms that drive neural tube closure. The work is exceptional in its development of tools to use CRISPR interference to screen for genes that regulate morphogenesis in human PSC organoids. The additional characterization of the role of specific transcription factors in neural tube formation is solid. The work provides both technical advances and new knowledge on human development through embryo models.

      In this important study, the authors engineered and characterised novel genetically encoded calcium indicators (GECIs) and an analytical tool (CaFire) capable of reporting and quantifying various sub-synaptic events, including miniature synaptic events, with a speed and sensitivity approaching that of intracellular electrophysiological recordings. While the evidence supporting the improvements in the speed and accuracy of these tools is convincing, including additional information about key imaging parameters, the Bar8f experiments, and CaFire would strengthen the study. This work will be of interest to neurobiologists studying synaptic calcium dynamics in various model systems.

      This valuable work shows that subcortically-generated behaviors, like grooming, can have widespread representations in cortical activity. While the evidence is solid, additional analyses are necessary to strengthen the claims associated with outsized cortical representations of grooming onsets, as well as to address atypical grooming events. This work will be of interest to neuroscientists interested in how subcortically-generated behaviors are represented across the cortex.

The strength of the evidence is largely convincing, as the authors establish the necessity and causality of key neuronal components using multiple genetic tools and functional dissection in a well-validated model organism.

However, the experimental evidence is incomplete and does not robustly support these claims, and the lack of a cohesive model connecting the findings weakens the overall impact. While the data suggest that Shot, actin, and microtubule nucleation contribute to dendritic pruning, their precise interplay remains unresolved.

      In this useful study, the authors conducted a set of computational and experimental investigations of the mechanism of cholesterol transport in the smoothened (SMO) protein. The computational component integrated multiple state-of-the-art approaches such as adaptive sampling, free energy simulations, and Markov state modeling, providing support for the proposed mechanistic model, which is also consistent with the experimental mutagenesis data. However, substantial revisions are needed for the discussion of the computational results and interpretation of the literature to provide a more balanced and accurate perspective on cholesterol-mediated SMO regulation. In the current form, therefore, the strength of evidence of the study is considered incomplete.

Much of the analysis is solid, but a more fine-scale analysis of demographic history could have led to more interesting findings. In addition, there are concerns about the selection analyses, given the special nature of the studied population and sampling scheme. Finally, lack of data availability limits the broader value of the paper.
