With a carefully collected dataset and compelling analyses, this fundamental manuscript demonstrates detailed links between societal and academic interest and natural species across the globe. In doing so, the authors reveal biases that may be diminishing our abilities to care for the species on our planet that may need our care the most. While some parts of this manuscript reflect previously published work, the authors are commended for putting all the puzzle pieces together for the first time. Their work highlights our uneven knowledge of biodiversity and its potential causes.

eLife assessment

This study reports the fundamental discovery of a novel structure in the developing gut that acts as a midline barrier between left and right asymmetries. The evidence supporting the dynamics, composition, and function of this novel basement membrane in the chick is in parts solid and in others convincing, but the investigation of its origin and impact on asymmetric organogenesis is not yet conclusive. This careful work is of broad relevance to anyone interested in patterning mechanisms, the importance of the extracellular matrix, and laterality disorders.

This Research Advance provides compelling evidence connecting the ancient Egyptian trade of baboons with the ancient port city of Adulis. Combining ancient DNA methods from a single mummified baboon with historical accounts, this work fundamentally advances our understanding of the ancient baboon trade in the Red Sea. Some additional reporting of DNA contamination will make the evidence provided even stronger.

The authors previously developed a tool with the goal of non-toxic trans-synaptic tracing using a modified rabies virus, an important goal for the neuroscience field. The tool has the propensity to accumulate mutations over time that promote toxicity, and the manuscript here describes techniques to avoid these mutations. It remains important to show that the non-mutated virus can serve as an effective trans-synaptic tracing tool.

This important study shows that tree shrews can detect optogenetic stimulation of the lateral geniculate nucleus (LGN) after training detection of visual stimuli. The solid evidence links optogenetic stimulation of the LGN to behavioural detection and neurophysiological responses. This paper is potentially of interest to neuroscientists and clinicians working on the visual system and visual prostheses.

eLife assessment

Secondary cell walls support vascular plants and conduct water throughout the plant body, and are crucial resources for lignocellulosic feedstocks. Here the authors present convincing genetic and biochemical evidence that secondary cell wall synthesis, known already to be under complex transcriptional control, is also controlled post-transcriptionally by MUSASHI-like RNA-binding proteins. These important results point to a new mechanism for control of secondary cell wall synthesis, which will be interesting to cell biologists and biochemists studying and attempting to manipulate plant biomass.

eLife assessment

Dolgova et al present a well-written and important manuscript focused on the mechanism of MEMO1 function in tumor cells. The authors explore whether the mechanism of MEMO1 overexpression in breast cancer, especially TNBC, is related to regulating iron given evidence that MEMO1 binds multiple proteins in the iron regulation pathway. While the data is in part compelling, the claims are based on indirect evidence for a central role of MEMO1 in tumorogenesis and perhaps metastasis via its effect on iron homeostasis.

eLife assessment

FKBP35 is the only FK506-binding protein present in the malaria-causing parasite Plasmodium falciparum, and has been considered a promising drug target due to its high affinity to the macrolide compound FK506, an immunosuppressant with antiplasmodial activity. This study demonstrates the essentiality of FKBP35 in parasite growth, based on compelling genetic evidence. The data also suggest that FK506 may exert its antimalarial activity through FKBP35-independent mechanisms that have not yet been characterised. This important study will be of interest to scientists working on the parasite biology and antimalarial drug development.

eLife assessment

This valuable study reports on a positive feedback loop between ZEB2 and ACSL4, which regulates lipid metabolism to promote breast cancer metastasis.

eLife assessment

This important study reports how heat stress affects centromere integrity by compromising the loading of the centromere protein CENH3 and by prolonging the spindle assembly checkpoint during male meiosis in Arabidopsis thaliana. The evidence supporting the claims by live cell imaging is convincing, although deeper mechanistic insight is lacking, making the study overall somewhat preliminary in nature. This work will be of interest to a broad audience of biologists working on how chromatin states are affected by stress conditions.

eLife assessment

This study identifies several modes of regulation or pathways that are valuable for understanding the entry or progression into meiosis, which implies both the repression of some mitotic cell cycle regulators and the expression of meiotic functions.

eLife assessment

This fundamental study significantly advances our understanding of the role of water influx and swelling in neutrophil migration.

This paper will be of interest to cell biologists and biophysicists working on cell migration.

eLife assessment

In this fundamental work, the authors demonstrated that maternal choline supplementation improved spatial memory, reduced hyperexcitability, and restored NeuN expression in a familial Alzheimer's disease mouse model. Interestingly, choline deficiency increased mortality, while paradoxically reduced hyperexcitability. Using behavior, electrophysiological, and histological measures, the authors present solid and convincing evidence supporting the significant role of maternal choline supplementation in protecting hippocampal functions vulnerable to Alzheimer's disease.

eLife assessment

This study reports the discovery of a new circuit mechanism for light-avoidance behavior in the marine annelid, Platynereis dumerilii. Using calcium imaging, molecular perturbations, behavioral measurements, and modeling, the authors provide compelling evidence that nitric oxide is released by postsynaptic neurons onto ciliary photoreceptors to prolong and enhance their response to ultraviolet light. The fundamental new role of nitric oxide described in this study may be conserved across animal phyla and thus will be of broad interests to neuroscientists and neuroendocrinologists.

eLife assessment

This important manuscript reveals signatures of co-evolution of two nucleosome remodeling factors, Lsh/HELLS and CDCA7, which are involved in the regulation of eukaryotic DNA methylation. The results suggest that the roles for the two factors in DNA methylation maintenance pathways can be traced back to the last eukaryotic common ancestor and that the CDC7A-HELLS-DNMT axis shaped the evolutionary retention of DNA methylation in eukaryotes. The solid evolutionary analyses form a strong basis for experimental follow-up studies. The work should be of interest to colleagues in the fields of evolutionary biology, chromatin biology and genome biology.

The convincing data substantially support the conclusions, and the work is important for understanding islet cell function and glucose homeostasis.

eLife assessment

The authors describe a method to decouple the mechanisms supporting pancreatic progenitor self-renewal and expansion from feed-forward mechanisms promoting their differentiation.

The strength of evidence is solid in that the methods, data and analyses broadly support the claims with only minor weaknesses.

eLife assessment

This study highlights new insights into the mechanism of pheochromocytoma pathogenesis that remains poorly understood. In the context of hereditary syndromes, such as multiple endocrine neoplasia 2 (MEN-2), where RET mutation is the major driver of thyroid, parathyroid, and adrenal pathologies, including pheochromocytoma, this mechanistic dissection of RET and TMEM127 is fundamentally sound. While the significance was deemed important, the strength of the evidence was found to be solid, although additional validation work would strengthen the findings.

eLife assessment

This study provides insights into the early detection of malignancies with noninvasive methods by developing a framework, which assesses methylation, CNA, and other genomic features.

This important study will demonstrate its practical impacts in the clinic and other researchers of the field.

eLife assessment

This manuscript reports a useful computational study of information encoding across the monkey prefrontal and pre-motor cortices during decision making. While many of the conclusions are supported with solid analyses, the evidence for the main claim, the role of an information bottleneck across areas, is incomplete. Refocusing the paper as an RNN modeling study would increase its appeal to a systems and computational neuroscience audience.

eLife assessment

This study develops valuable tools for optogenetic control of neuronal activity. The basic characterization of the activation of a red-shifted channelrhodopsin paired with a blue-light sensitive anion channel engineered to obtain desired inhibitory current kinetics is solid. However, guidelines and feasibility for their practical use under simultaneous multi-color stimulation are incomplete, as are comparisons with current state-of-the-art tools.

eLife assessment

The study used slice physiology and modeling to investigate neurotransmitter release at the cerebellar parallel fiber-to-molecular layer interneuron synapse, revealing that each docking site can accommodate up to two synaptic vesicles simultaneously. The authors have provided convincing evidence addressing how many vesicles can be released by a single release site in a short time. These findings are important for the validation of a two-step docking model and shed light on the mechanisms underlying short-term synaptic plasticity and strategies for achieving synaptic reliability, which plays a critical role in information processing in the brain.

eLife assessment

Pak et al. examined the relationship between the most common spatial patterns of neurodegeneration and the density of different cell types in the cerebral cortex. The study uses innovative methods but the main claims are incompletely supported due to some limitations. While the results might be considered preliminary, this work provides valuable findings and takes a step in the right direction by highlighting the contribution of non-neuronal cell type to the pathobiology of neurodegeneration.

eLife assessment

This fundamental study substantially advances our understanding of the role of zinc in metabolism, specifically a newly established clinical link between mutations in the zinc transporter SLC39A5, elevated serum zinc levels, and a reduction in the risk of Type 2 Diabetes. The provided evidence is solid with state-of-the-art genetic analysis of large human cohorts followed by a comprehensive analysis of a mouse SLC39A5 knockout mutant, establishing that SLC39A5 plays a role in hepatic lipid handling through AMPK signaling, although the limited analysis of a pancreatic phenotype that has previously been described constitutes a weakness. This study will be of relevance to researchers interested in metabolism, fatty liver disease, and the biology of trace elements.

eLife assessment

This valuable study provides a new perspective on preparatory activity occurring before the onset of movement. The authors report that, for a wide variety of recurrent networks, the optimal inputs should start before the desired network output. The authors present convincing evidence by combining mathematically tractable analyses in linear networks and numerical simulation in nonlinear networks. One limitation is that the only cost function considered for the input is that of magnitude. While this constraint is reasonable, it is suspected that other cost functions could lead to greater realism of model responses.

eLife assessment

This valuable study advances our knowledge of the effects of anxiety/depression treatment on metacognition, demonstrating that treatment increases metacognitive confidence alongside improving symptoms. The authors provide convincing evidence for the state-dependency of metacognitive confidence, based on a large longitudinal treatment dataset. However, it is unclear to what extent this effect is truly specific to treatment, as changes in metacognitive confidence in the group receiving online CBT were not statistically different from those in the control group.

eLife assessment

In this fundamental study, the authors propose analytical methods for inferring evolutionary parameters of interest from sequencing data in healthy tissue relevant to hematopoiesis. By combining analyses of single cell and bulk sequencing data, the authors can use a stochastic process to inform different aspects of genetic heterogeneity. The strength of evidence in support of the authors' claim is thus compelling. The work will be of broad interest to cell biologists and theoretical biologists.

eLife assessment

This important study identifies a spatial pattern of neural activity that corresponds to trust in an investment game. It provides a compelling assessment of the validity of this pattern by assessing its expression, or lack thereof, in a variety of datasets.

eLife assessment

This important study advances our understanding of how listeners understand speech when there are multiple talkers by showing that the content of the speech affects acoustic processing.

The work will be of use to researchers interested in the neuroscience of speech and language processing.

eLife assessment

This is an important contribution that extends earlier single-unit work on orientation-specific center-surround interactions to the domain of population responses measured with Voltage Sensitive Dye (VSD) imaging and the first to relate these interactions to orientation-specific perceptual effects of masking. The authors provide convincing evidence of a pattern of results in which the initial effect of the mask seems to run counter to the behavioral effects of the mask, a pattern that reversed in the latter phase of the response. It seems likely that the physiological effects of masking reported here can be attributed to previously described signals from the receptive field surround.

eLife assessment

This is an important study that improves gene models for the ferret genome and identifies neural progenitors that are comparable to those found in developing human brains. The data are convincing and clearly presented. Of particular interest to the field, the work identifies enriched expression of FOXJ1 in late truncated radial glia, strongly indicating that towards the end of neurogenesis, these cells likely give rise to ependymal cells. The work is of interest to anyone studying the development of the nervous system, especially colleagues studying the evolution of development.

eLife assessment

This manuscript will provide a valuable method to evaluate the safety of MR in patients with orthopaedic implants, which is required in clinics.

eLife assessment

This is important work that examines hepatic acetate production via ACOT12/18 in starvation and diabetes. The investigators use solid loss of function strategies in cells, including mouse primary hepatocytes, and in vivo mouse experiments to show that ACOTs are necessary for normal acetate production in the context of fasting and type 1 diabetes. Given that acetate is commonly thought to primarily represent a fermentation product, this study is of interest as it describes hepatic pathways converting fatty acids to acetate.

eLife assessment

This useful study presents convincing evidence that blood meal source and season affect Culex quinquefasciatus mosquito reproduction. Its unique focus on the interactive effects of both factors on mosquito fitness is of considerable relevance for the field, but the work suffers from inadequate experimental design - no replication, a population mismatch with the hypothesis region, and small sample sizes, limitations that were not sufficiently acknowledged in the discussion. The work will be of interest to those studying malaria and vector-borne diseases.

eLife assessment

This important study introduces a new therapeutic cell targeting system, where an active molecule is divided into inactive or less active parts that are subsequently linked via a bridging receptor on a target cell. Solid experimental proof of concept involving the activation of Wnt signaling in hepatocytes is presented, which could be further strengthened by demonstrating the specificity of the effect when applied to a mix of different cell types. This study may be of substantial interest to medical biologists focused on targeted therapeutics or seeking to utilize cell type-specific pathway modulation in their research.

eLife assessment

This study provides an important demonstration of how the false-positive rate of high-resolution 2D template matching to find particles of a given target structure in 2D cryo-EM images (2DTM) relates to overfitting the data towards the template. The authors present new methods to measure the amount of model bias that gets introduced in high-resolution features of such maps, with compelling evidence that high-resolution features that are not present in the template can still be reconstructed in 3D from images obtained by 2DTM. The paper could be strengthened by the inclusion of a more elaborate discussion (and possibly additional experiments) to describe the limitations of 2DTM for smaller target structures.

eLife assessment

This study presents valuable findings on the role of the small GTPase Rab3A in homeostatic plasticity. While the study demonstrates that Rab3A is required for homeostatic scaling, the evidence supporting the model put forward by the authors is incomplete. The work will be of interest to researchers in the field of synaptic transmission and plasticity.

eLife assessment

This is an important study that addresses a significant question in microbiome research. The authors provide convincing evidence that certain bacterial groups within the fly microbiome have critical functions for host development. Additionally, dietary aspects such as microbial community progression in a natural food source are integrated into their host-microbe interaction analyses.

eLife assessment

This manuscript analyzes large-scale Neuropixels recordings from visual areas and hippocampus of mice passively viewing repeated clips of a movie and reports that neurons respond with elevated firing activities to specific, continuous sequences of movie frames. The important results support a role of rodent hippocampal neurons in general episode encoding and advance understanding of visual information processing across different brain regions. The strength of evidence for the primary conclusion was found to be convincing.

eLife assessment

This is an important study that tests the effects of using neurofeedback, in the form of reward delivery when large sharp wave-ripples (SWRs) are detected, on neurophysiological and behavioral measures. The authors provide convincing evidence that the rate of SWRs increased prior to reward delivery and decreased in the period after reward delivery, with no significant effect on memory performance. The ability to manipulate SWR rate in a naturalistic way is a potentially exciting new tool for studies that seek to understand the function of SWRs.

eLife assessment

This manuscript represents a cleanly designed experiment for assessing biological motion processing in children (mean age = 9) with and without ADHD. The group differences concerning accuracy in global and local motion processing abilities are solid, but the analyses suggesting dissociable relationships between global and local processing and social skills, age, and IQ need further interrogation. The results are useful in terms of understanding ADHD and the ontogenesis of different components of the processing of biological motion.

eLife assessment

In this important study, the authors develop a promising experimental approach to a central question in ecology: What are the contributions of resource use and interactions in the shaping of an ecosystem? For this, they develop a synthetic ecosystem set-up, a variant of SELEX that allows very detailed control over ecological variables. The evidence is convincing, and the work should be of broad interest to the ecology community, leading to further quantitative studies.

eLife assessment

This important paper reports on the redistribution of Pol V and DNA methylation from euchromatic to heterochromatic regions in H1 mutants. While some of the evidence is solid, other parts of the genome-level model proposed to explain the molecular phenotype of H1 mutants (which includes a reduction of DNA methylation at some euchromatic sites) would benefit from additional experimental support. The work will be of broad interest to individuals interested in the mechanisms that have evolved to partition eukaryotic genomes into euchromatic and heterochromatic regions.

eLife assessment

This important study combines experiments and theory to develop a sex-based in silico model of arterial myocytes. The ionic currents of the model and its sex difference based on experimental data and comparisons of model properties with experimental data at the single cell and tissue scale are convincing. If the rigor used to assess the model (specifically the simplicity of the 1D vessel model) was improved, and there was an addition of quantitative analysis of the data examining similarity between male/female experimental/simulation, the paper would be improved.

eLife assessment

The study by Deichsel et al. reports valuable findings that suggest a new, possibly conserved, mechanism by which post-translational modification of a Notch regulator mediates the cellular immune response. However, the claims are only partially supported as the data and analysis are incomplete. The work will be of interest to biologists working on immune cell development or regulation of Notch.

eLife assessment

In this valuable study, patients homozygous for both minor frequency alleles of the APOL1 gene are shown to be at significant risk for progression into sepsis after infection.

This study presents a valuable finding for the treatment of PCCs by sequencing 16 tumor specimens from five patients with pheochromocytomas by single-cell transcriptomics and proposing a new molecular classification criterion based on the sequencing results and characterization of tumor microenvironmental features. The evidence supporting the claims of the authors is solid, although the inclusion of more patient samples would strengthen the study's conclusions. The work will be of interest to clinicians or medical biologists working on rare pheochromocytomas (PCCs).

eLife assessment

The authors present a potentially useful model involving Ca2+ signaling in inflammasome activation. As it stands, it was felt that the data were not sufficient to support the model and the claims of the study are inadequately presented.

eLife assessment

This important study describes the discovery and further engineering of a red light-activated, chloride-conducting Channelrhodopsin (ACR) that could be used to inhibit neuronal activity. The authors were able to demonstrate some inhibition of neuronal activities in vitro and in vivo with 635 nm light, however the study was incomplete. Adequate controls and direct comparisons to the performance of already-established variants were missing, making it difficult to confirm the future utility of MsACR1 and raACR1.

eLife assessment

This paper describes a new complexity estimator for time series based on state-space modeling, which can directly decompose signal entropy in both time and frequency. The authors compare their estimator to Lempel-Ziv (LZ) complexity using a variety of time series neurophysiological data from humans and non-human primates. This represents a potentially valuable methodological contribution for existing studies using LZ complexity in their analyses, although the paper currently ignores much of the existing literature which has already developed related solutions to the same issues. The strength of the evidence supporting the superiority of the new complexity metric is currently incomplete, and should be backed by additional analyses.

eLife assessment

This paper presents an important contribution to the field of hippocampal registration by introducing a novel surface-based approach that utilizes the topological and morphological features of the hippocampus for anatomical registration across individuals, rather than volumetric-based methods commonly used in the literature. The study provides compelling evidence for the efficacy of this approach using histological samples from three different datasets and offers validation of the method through comparison with traditional volumetric registration. This is important work given the large number of studies that examine hippocampal shape, thickness, and function in large cohorts, providing strong support for the use of hippocampal unfolding methods in future studies.

eLife assessment

This important and compelling study investigates the problem of intracellular acidification induced by commonly-used optogenetic stimulating opsins. The low proton permeability of two high-performance opsins is shown to reduce photostimulated acidification. The findings may be of broad interest in the fields of neuroscience research and optogenetic therapies.

eLife assessment

This study presents important findings indicating that gradients of functional connectivity are present in the human foetal brain, and that these gradients develop further during gestation, particularly in multisensory brain regions. The study uses state-of-the-art connectomic mapping techniques. However, recent findings suggest that such gradients may reflect confounds within the analysis technique more than underlying brain functions. The evidence for the authors' claims therefore currently appears inadequate as it does not account for these potential confounds.

eLife assessment

This important study uses a combination of computational modeling and glutamate imaging to show how a particular synaptic organization referred to as space-time wiring has a limited contribution to a dendritic computation that occurs in the retina. The evidence supporting the claims of the authors is convincing, although the findings are largely confirmatory of previous modeling and experimental results. The work will be of interest to retinal neurobiologists and neurophysiologists interested in dendritic computations.

eLife assessment

The finding that Fusicoccin promotes locomotor recovery after spinal cord injury is useful, and the idea of harnessing small molecules that may affect protein-protein interactions to promote axon regeneration is interesting and worthy of study. However, the main methods, data, and analyses are inadequate to support the primary claim of the manuscript that a 14-3-3-Spastin complex is necessary for the observed Fusicoccin effects.

eLife assessment

Franke et al. explore and characterize the color response properties in the mouse primary visual cortex, revealing specific color opponent encoding strategies across the visual field.

eLife assessment

This study presents valuable findings on the roles of the axon growth regulator Sema7a in the formation of peripheral sensory circuits in the lateral line system of zebrafish.

The work will be of interest to developmental neuroscientists studying circuit formation.

eLife assessment

This valuable study has the potential to shed mechanistic light on how attention mechanisms that influence competition between multiple visual stimuli are modulated by the relative neural similarity of these stimuli.

The evidence supporting the claims of the authors is solid, although validation of the results is needed to further strengthen the major conclusions of the work. The work will be of broad interest to biophysicists and biochemists.

eLife assessment

This paper presents data suggesting the novel finding that stimulating the senses can open the normal barrier to the brain and lead to changes in the brain.

However, the reviewers considered the potential significance of the study to be important.

eLife assessment

This study suggests that PAK3 may play a critical role in cognitive function after cranial irradiation, highlighting a potential therapeutic target to mitigate the adverse effects of radiotherapy.

eLife assessment

This paper presents a valuable pipeline based on state-of-the-art analytical software that was used to study genetic pleiotropy between neuropsychiatric disorders. The presented evidence supporting the claims is solid, although the paper is lacking an appropriate comparison to previously published methods as well as a more detailed exploration of some of the findings. The created pipeline is made publicly available and can thus be used by researchers from diverse fields to study different combinations of diseases and traits.

eLife assessment

Chang et al. provide glutamate co-expression profiles in the central noradrenergic system and test the requirement of Vglut2-based glutamatergic release in respiratory and metabolic activity under physiologically relevant gas challenges. Their experiments provide compelling evidence that conditional deletion of Vglut2 in noradrenergic neurons does not impact steady-state breathing or metabolic activity in room air, hypercapnia, or hypoxia. This study provides an important contribution to our understanding of how noradrenergic neurons regulate respiratory homeostasis in conscious adult mice.

eLife assessment

Multimodal experiences that for example contain both visual and tactile components are encoded as associative memories. This manuscript is a valuable contribution supporting structural and functional brain plasticity following associative training protocols that pair together different types of sensory stimuli. The results provide solid support for this plasticity being a basis for cross-modal associative memories.

eLife assessment

This fundamental study provides a unique tool for assessing the range of phosphorylation in insulin reactions due to genetic variation and dietary influence through the utilization of genetically distinct mouse strains. The discoveries of this study hold substantial importance, as they shed light on the interplay between genetic attributes and environmental conditions in shaping the insulin-signaling network within skeletal muscle, a crucial regulator of metabolism.

eLife assessment

This study presents valuable new insights from the protist Tetrahymena regarding radial spokes, conserved protein complexes that are important for cilia motility. The work employs interdisciplinary approaches to provide convincing support for radial spoke composition with some experiments, but there are weaker areas with partially incomplete support, such as relying on knockouts alone rather than including localization studies of tagged proteins.

This valuable work explores how transcription factors regulate transcription through cooperative binding to enhancers. Through experiments and modeling, the authors show convincingly that the cooperativity of transcription factor binding regulates transcriptional bursting and the extent of the amount of time that the target promoter remains in an active state.

eLife assessment

This manuscript reports important new results, but it provides incomplete support for its claims. Recent data has shown that schizophrenia-related synaptic alterations induce changes in neural network synchrony, and this manuscript provides the first theoretical understanding of the underlying network mechanisms. Proper support for this result, however, requires a tighter link between the computational model and the experimental data and a more in-depth understanding of the model mechanisms.

eLife assessment

In this important study, Esmaily and colleagues investigate the "confidence matching" between two agents and present a useful exploration of its computational and physiological correlates. Further analyses would be helpful to provide a tighter link between fluctuations of confidence, pupil size, EEG response, and computational variables, to delineate the causal relations between these quantities, which are nevertheless incompletely documented at present.

eLife assessment

This elegantly performed and rigorous study generates new and conceptually important insights into the interaction between an essential malaria parasite invasion ligand (and vaccine candidate) called PfRH5, and its erythrocyte surface integral membrane receptor basigin. The authors provide compelling evidence based on rigorous biochemical assays that erythrocyte basigin is predominantly expressed in a complex with one of two distinct erythrocyte membrane proteins called PMCA and MCT1 and that PfRH5 binds to these complexes better than to isolated basigin. Certain invasion-inhibitory antibodies, that do not prevent binding of PfRH5 to isolated basigin, do in contrast prevent binding to the basigin complexes, explaining the mode of action of these previously enigmatic antibodies and providing valuable data towards the improved design of vaccines based on PfRH5.

This study provides a potentially useful assessment of the effect of testing contacts of cases in school classes when identified, rather than at the end of quarantine, on both the number of secondary infections and other outcomes including tracing delay and identification of the possible source of infection. The authors find that the intervention likely led to a decrease in tracing delay and an increase in the number of possible sources of infection, though were unable to determine whether secondary transmission decreased, due in part to unmeasured confounding. While the surveillance system described provides a solid dataset appropriate for this analysis, the description of methods, study outcomes, and consideration of potential confounding factors is incomplete.

The manuscript describes a set of detailed modeling and experimental studies to disentangle the respective roles of gap junctional electrical vs. metabolic coupling mechanisms in the synchronization of islet activity. This is of interest due to the importance of islet synchronization and generally islet network properties in the regulation of insulin secretion from the pancreas. The significance of the findings was judged to be mostly important and the strength of evidence provided was judged to be mostly solid overall.

In this study, Sparta et al., generated and employed a battery of fluorescent reporters that allowed them to perform time-resolved monitoring of mechanistic target of rapamycin complex 1 (mTORC1) responses to stimuli including glucose, amino acids, and insulin at the single cell resolution. The results of this elegant approach support a model of graded mTORC1 activation in response to the aforementioned stimuli when applied individually or in combination. This model is consistent with continuous adjustment of mTORC1 signaling to changes in cellular environment and opposed to the "on/off" model of mTORC1 function. Considering the pivotal role of mTORC1 in integrating signals such as nutrients, hormones, growth factors, oxygen, and energy status with a plethora of outputs that affect cell fate and organismal physiology, it was thought that this study will be of interests across a variety of biomedical disciplines. Overall, the elegance and robustness of the approach was highly appreciated, though the paper would be strengthened by addressing some technical issues and concerns regarding the positioning of the proposed model of mTORC1 regulation in the field.

Large scale cell movements occur during gastrulation in vertebrate embryos but their role in this major morphogenetic transition in formation of the body plan is poorly understood. Using the chick embryo model system, this study makes important advances using elegant methods to show that extension of the primitive streak during gastrulation, occurring through cell proliferation, polarisation and intercalation, and large-scale polonaise cell movements, can be uncoupled. Although the driving mechanism and precise role of these movements remains a mystery, the study provides convincing evidence for the uncoupling through independent approaches, the most creative of which are the effects shown after induction of a supernumerary primitive streak.

This important study reports a new mutant mouse with compromised function of one of the BRCT repeats of TOPBP1, a DNA damage response protein. Mutant mice are viable but males are sterile, owing to the lack of spermatocytes beyond the late pachynema stage of the first meiotic prophase. Using immunofluorescence, phospho-proteomics and single-cell sequencing of cells in the testis, the authors provide solid evidence that the animals are defective in the maintenance (but not the initiation) of sex chromosome inactivation in pachynema. The report is of interest to researchers in the fields of meiosis as well as gene silencing/sex chromosome inactivation.

The role of CRB3A/B in ciliogenesis was discovered several years ago in epithelial cells and in vivo, but the mechanism by which CRB3A/B regulates ciliogenesis has been unknown. Here, the authors confirm the requirement of CRB3A/B expression for primary ciliogenesis in both mouse and human cells and propose a mechanism by which CRB3A/B promotes ciliogenesis. The results are useful but currently incomplete: further experimentation and data analysis are needed to support some of the authors' central claims.

This paper demonstrates valuable evidence for genetic redundancy of the COUPTF transcription factors in hippocampal development by creating conditional compound knockouts in combination. Authors aim to demonstrate specific and complementary roles of the two COUPTF homologues. The paper uses convincing methods that includes both anatomic and behavioral studies for the roles of these factors. However, the strength of evidence was incomplete, due to the use of a Cre line that was not adequately described, and lack of concordance with expression domains of the COUPTF factors with the published literature dampened enthusiasm. This concern is expressed by reviewers in the interpretation of some of the finding that may require additional experiments in the future.
