This study provides valuable insights into the role of MATR3 in oocyte maturation and folliculogenesis, using conditional knockout mice and in vitro follicle culture systems to show that MATR3 is required for oocyte growth and gene transcription, with downstream effects on follicle development. The strength of the evidence is incomplete, as key findings lack independent validation, methodological details are insufficient, and inconsistencies in data presentation reduce confidence in the conclusions. The work will be of interest to researchers in reproductive biology and fertility.

eLife Assessment

This important study combines cryo-EM, biochemical, and cell-based assays to examine how Gβγ interacts with and potentiates PLCβ3. The authors present evidence for multiple Gβγ interaction surfaces and argue that Gβγ primarily enhances PLCβ3 activity after membrane recruitment rather than serving mainly as a membrane-recruitment factor. The evidence is solid overall, although uncertainty remains about the physiological relevance and precise arrangement of the proposed interfaces because the structural model relies on engineered crosslinking.

eLife Assessment

Kim et al. provide important findings explaining how T3SS assembly is regulated by a conserved genetic context. The evidence supporting the conclusions is compelling, with numerous experiments demonstrating the validity of the findings. The work will be of interest to molecular biologists, biochemists, and microbiologists working on secretion systems or similar complexes. Further studies revealing similar mechanisms in other systems would enhance the impact of the current study.

eLife Assessment

This valuable study presents a comparative dataset on crab locomotion to examine the evolution of sideways walking. The evidence supporting the authors' claims is largely convincing. This work will be of interest to researchers in animal locomotion.

eLife Assessment

This important study shows that orientation tuning of V1 neurons is suppressed during a continuous flash suppression paradigm, especially in neurons with binocular receptive fields. These findings, made using cutting-edge imaging techniques, convincingly implicate early visual processing in continuous flash suppression, in agreement with previous studies suggesting reduced effective contrast of such stimuli in V1.

eLife Assessment

The authors adapt sequencing of nascent DNA (DNA linked to an RNA primer, "SNS-Seq") to map DNA replication origins in Trypanosoma brucei. The main impact of this work is reporting a new set of putative origins, which do not overlap with previously reported origins, but which appear to overlap with previously mapped DNA-RNA hybrid (R-loops). Thus, these valuable findings open up new avenues for further investigation into the mechanistic basis for firing of replication forks in this organism. However, the supporting evidence remains incomplete and would benefit from orthogonal validation. This work will be of interest to those studying DNA replication and epigenetic regulation of fork origins.

eLife Assessment

This important work provides a new method to extract cfDNA from residual plasma from heparin separators for molecular testing. The evidence supporting the authors' claims is convincing, although some further metrics should also be evaluated. This finding will be interesting to people working in epigenomics and infectious disease diagnostics.

eLife Assessment

Ge et al here report a structural study of the native tripartite multidrug efflux pump complexes from Escherichia coli that identifies a novel accessory subunit, YbjP, the structure of the native TolC-YbjP-AcrABZ complex, as well as structures of the AcrB protein in L, T, and O conformations. The strength of the structural data is compelling, and the importance of the findings is potentially fundamental. In the revised manuscript, the authors have included additional analysis and made comparisons with pre-existing data which has helped place the data and its impact in the proper context.

eLife Assessment

This important study examined age-related changes in cerebellar function by testing a large sample of younger and older adults, including 30 over 80 years old, on motor and cognitive tasks linked to the cerebellum and conducting structural imaging. Their findings show that cerebellar-dependent functions are mostly maintained or even enhanced across the lifespan, with cerebellar-mediated motor abilities remaining intact despite degeneration, in contrast to non-cerebellar measures. Overall, the authors provide compelling evidence in support of preserved cerebellar function with age. These results highlight the resilience and redundancy of cerebellar circuits and offer key insights into aging and motor behavior.

eLife Assessment

This valuable article provides a convincing and very detailed model of the process regulating the assembly of the spore coat in the model spore-forming bacterium Bacillus subtilis. It focuses on SafA, a morphogenetic coat protein involved in the assembly of the spore coat inner layer, deciphering the contributions of disulfide bond formation and crosslinking reactions catalyzed by a transglutaminase. The process had been studied with a combination of genetics and microscopy, but this is the first complete assessment incorporating detailed biochemical approaches.

eLife Assessment

This valuable study aims to determine mechanisms underlying breast cancer initiation and tumour progression. The manuscript includes a solid set of transcriptomic and proteomic datasets from tumour samples and examines mitochondrial function within the tumours. While the underlying mechanisms linking expression changes to functional effects remain speculative. This paper provides a resource for researchers working on breast cancer and/or HER2-driven bioenergetics changes.

eLife Assessment

This important study addresses the contribution of pericytes to the organization and permeability control of the zebrafish blood-brain barrier (BBB). By analyzing pdgfrb mutant zebrafish that lack brain pericytes, the authors reveal that the resulting cerebrovascular network is abnormally patterned. Remarkably, however, the barrier retains its restrictive permeability during larval and juvenile stages. More pronounced vascular defects become evident in adults, where localized BBB leakage coincides with hemorrhages and aneurysm formation. Based on convincing and beautifully documented imaging data, the authors argue that, unlike what has been reported in rodent systems, pdgfrb-dependent pericytes are not essential for maintaining BBB integrity in the zebrafish brain.

eLife Assessment

The authors aim to understand why Kupffer cells (KCs) die in metabolic-associated steatotic liver disease (MASLD). This is a valuable study using in vitro studies and an in vivo genetic mouse model, suggesting that increased glycolysis contributes to KC death in MASLD. The data presented are now convincing and adequately revised. This work will be of interest to researchers in the immunology and metabolism fields.

eLife Assessment

The present manuscript by Cordeiro et al., shows convincing evidence that α-mangostin, a xanthone obtained from the fruit of the Garcinia mangostana tree, behaves as a strong activator of the large-conductance (BK) potassium channels. The authors suggest that α-mangostin activation of the BK channel is state-independent, and molecular docking and mutagenesis suggest that α-mangostin binds to a site in the internal cavity. Additionally, the authors show that α-mangostin can relax arteries, further suggesting the plausibility of the proposed effects of this compound. These are valuable findings that should be of interest to channel biophysicists and physiologists alike.

eLife Assessment

This study introduces a valuable toolkit for zebrafish transgenesis, significantly enhancing the flexibility and efficiency of transgene generation for immunological applications. The authors provide convincing evidence through well-designed experiments, demonstrating the toolkit's utility in generating diverse and functional transgenic lines.

eLife Assessment

This study maps the genotype-phenotype landscapes of three E. coli transcription factors and the topographical features of these landscapes. It shows that ruggedness and epistasis do not hinder the evolution of strong transcription factor binding sites. These convincing findings contribute important insights into fitness landscape theories and highlight the role of chance, contingency, and evolutionary biases in gene regulation. The authors then study the topographical features of these landscapes, especially the number and distribution of local maxima, as well as the statistical properties of evolutionary paths on these landscapes.

eLife Assessment

Findings from this study are considered fundamental because they identify amino acid uptake, cholesterol synthesis, and protein prenylation as key metabolic regulators of B cell activation, proliferation, and survival, advancing understanding of T-independent immune responses. The study links metabolic reprogramming directly to B cell function, highlighting how cellular metabolism supports immune fitness. The evidence is compelling, combining unbiased proteomic profiling with genetic and pharmacological validation to demonstrate causal roles for these pathways.

eLife Assessment

This study represents a useful finding on the social modulation of the complex repertoire of vocalizations made across a variety of strains of lab mice. The evidence supporting the claims is, at present, incomplete, as numerous concerns regarding the appropriate categorization of vocalizations, the averaging of data points with disparate levels of occurrence, the interpretation of the function of noisy calls, and a general lack of adequate analyses of experimental data were raised. With these issues addressed, the work will be of importance to scientists studying rodent vocal communication.

eLife Assessment

This important paper substantially advances our understanding of how Molidustat may work, beyond its canonical role, by identifying its therapeutic targets in cancer. This study presents a compelling and well-structured investigation into the therapeutic vulnerabilities of APC-mutant colorectal cancer. This work will be of broad interest to the cancer community in studying small molecules and their therapeutic targets.

eLife Assessment

This study offers valuable insights into how humans detect and adapt to regime shifts, highlighting dissociable contributions of the frontoparietal network and ventromedial prefrontal cortex to sensitivity to signal diagnosticity and transition probabilities. The combination of an innovative instructed-probability task, Bayesian behavioural modelling, and model-based fMRI analyses provides solid support for the main claims. The addition of new model-comparison figures in revision effectively addresses the previously noted potential confound between posterior switch probability and time in the neuroimaging results. At the behavioural level, while the computational model captures the pattern of "system neglect" well, qualitatively distinct mechanisms, such as hyper-prior attraction toward experiment-wise mean parameters, reporting biases, or probability-outlier underweighting, could produce similar behavioural signatures and cannot be fully disambiguated with the current design alone; however, converging evidence from the authors' prior work partially mitigates this concern.

eLife Assessment

This study represents an important advance in our understanding of how certain inhibitors affect the behavior of voltage gated potassium channels. Robust molecular dynamics simulation and analysis methods lead to a new proposed inhibition mechanism with convincing strength of support. This study has considerable significance for the fields of ion channel physiology and pharmacology and could aid in development of selective inhibitors for protein targets.

eLife Assessment

In this manuscript, based on electron microscopy observations of C. elegans embryos, the authors make the bold claim that the plasma membrane ruptures during cell division and that closure of this opening by membrane extension contributes to cytokinesis. Although the findings are potentially valuable, the evidence in support of the authors' claims is inadequate.

eLife Assessment

This manuscript uncovers the importance of Vinculin in the maintenance of junctional integrity during neural tube closure in regions of increased mechanical stress, by using sophisticated methods such as laser ablation and live imaging. The manuscript also reports a novel application of an established embryonic stem cell protocol to efficiently generate mutant and transgenic embryos for analysis. The findings are fundamental in nature, significantly improve our understanding of a major research question, and are backed by compelling evidence. Whilst there is much to appreciate in this work, exactly how Vinculin mediates neural fold elevation remains unclear, and addressing this lacuna will significantly improve the strength of the manuscript; in addition, some rewriting for better clarity (including technical/methodological details) and inclusion of possible consequences of the increased number of tight junction gaps in the vinculin mutant would be pertinent.

eLife Assessment

This important study explores how the phase of neural oscillations in the alpha band affects visual perception, indicating that perceptual performance varies due to changes in sensory precision rather than decision bias. The evidence is convincing in its experimental design and analytical approach. This work should interest cognitive neuroscientists who study perception and decision-making.

eLife Assessment

This is an important study that addresses the role of fever as a conserved response to viral infection. It demonstrates that the heat-shock factor, HSF1, is activated by increased temperature during fever to enhance the anti-viral immune response. The data provides compelling evidence for the conclusions and the work will be of interest to virologists, immunologists, and cell biologists.

eLife Assessment

This article presents valuable findings on how the timing of cooling affects autumn bud set in European beech saplings. The study leverages extensive experimental data and provides an interesting conceptual framework for the various ways in which warming can affect bud set timing. The statistical analysis is very well considered, while indicating some factors that may temper the authors' claims. The factorial experiments offer solid support.

eLife Assessment

This important study combined careful computational modeling, a large patient sample, and replication in an independent general population sample to provide convincing evidence in support of a computational account of a difference in risk-taking between people who have attempted suicide and those who have not. It is proposed that this difference reflects a general change in the approach to risky (high-reward) options and a lower emotional response to certain rewards. While the findings advance our understanding of cognitive mechanisms at the group level, the observation that computational phenotype is predictive of suicidal behavior only in the clinical sample and not in the online sample limits its applicability for individual prediction, early detection and prevention of suicidality.

eLife Assessment

Using single-cell transcriptomic data from mouse inner ear hair cells, the authors compare for the first time gene expression across the four recognized hair cell types in adults, generating information fundamental to understanding hair cell relationships between the ancient vestibular compartment and the more recent cochlea. Among observed differences, compelling evidence is provided for the expression in vestibular hair cells but not cochlear hair cells of certain ciliary motility-related genes, suggesting that the kinocilium of vestibular hair cells may function as an active force generator to increase sensitivity.

eLife Assessment

This important work delineates layered glucose-responsive neuropeptidergic mechanisms that regulate sugar intake. Using a combination of genetic, physiological, and behavioral experiments, the authors convincingly show that Hugin- and Allatostatin A-releasing neurons suppress sugar feeding by reducing the sensitivity of Gr5a-expressing gustatory neurons. They further demonstrate that Neuromedin U neurons share key physiological properties with fly Hugin neurons, highlighting conserved peptide functions across animal phyla.

eLife Assessment

This important study developed a new sensor for TDP-43 activity that is sensitive and robust that should strongly impact the field's ability to monitor whether TDP-43 is functional or not. The evidence, though limited to cell culture, is compelling and is the first demonstration that a GFP on/off system can be used to assess genetic TDP-43 mutants as well as loss of soluble TDP-43.

eLife Assessment

This valuable study addresses mechanisms of feedback inhibition between planar cell polarity protein complexes during convergent extension movements in Xenopus embryos. The authors propose a conceptually new model, in which non-canonical Wnt ligand stimulates transition of Dishevelled from its complex with Vangl to Frizzled, with essential roles of Prickle and Ror in this process. The main observations supporting molecular interactions rely on modest but significant changes in protein association in response to Wnt11. While the study is limited due to insufficient phenotypic analysis at the cellular level and the use of exogenously supplied proteins, this work is convincing and will be of broad interest to cell and developmental biologists.

eLife Assessment

In this important study, a new multi-scale imaging workflow promises to accelerate and democratize comparative connectomics, with projectome-level data informing synapse-level connectivity. While the pipeline and time savings are convincing, the evidence for the segmentation methodology as a reusable community resource is incomplete, with key metrics like error rates, annotation times, and proof-reading times not reported. Furthermore, the evidence on the utility of projectome-level information for analysing brains appears misleading. By clarifying the findings and ensuring that the complete software pipeline is available in online open source repositories alongside precise documentation, the authors would deliver on their vision to enable any laboratory to map and analyse brain connectomes.

eLife Assessment

This manuscript demonstrates the feasibility and potential value of using functional MRI in awake, behaving mice, enabling assessment of distributed brain activity during ongoing behavior in a manner analogous to human fMRI. The valuable findings suggest that the periaqueductal gray (PAG), a midbrain structure classically linked to threat processing and aversive learning, also contributes to reversal learning. If supported, this result would carry theoretical and practical implications for our subfield by expanding the computational roles attributed to the PAG and motivating cross-species circuit-level investigations. However, the strength of evidence is, at present, incomplete, and several key claims are only partially supported by the current analyses.

eLife Assessment

This multi-omics study provides a comprehensive characterization of the context-dependent roles of the JAK-STAT pathway (JSP) across different cellular compartments within the breast cancer microenvironment. The authors present convincing evidence that high JSP activity paradoxically drives anti-tumor cytotoxicity in T cells but promotes malignancy and immunosuppression in tumor epithelial cells, leading to the fundamental discovery that broad JAK-STAT inhibition could be therapeutically counterproductive. Ultimately, the identification of the immune-related JSP score and the STAT4 axis as predictive biomarkers for anti-PD-1 immunotherapy response, particularly in triple-negative breast cancer, offers critical insights for precise patient stratification and targeted therapeutic interventions.

eLife Assessment

It remains unclear how human antibody-secreting cells (ASCs) differentiate. In this study, the authors discovered a CD30⁺ intermediate subset that appears during the transition from B cells to ASCs, providing a potential ontogeny for extra-germinal center B cell differentiation. This study is useful because it identifies novel intermediate markers that enable tracking of human ASC ontogeny, offering new insights into ASC development. However, the evidence is incomplete, and we see three major limitations: (1) the data are largely representative, requiring additional reproducibility; (2) the bioinformatics analysis is limited; and (3) step-wise phenotypic validation would require lineage-tracing experiments on sorted populations.

eLife Assessment

This important study offers insights into the anatomical and physiological features of cold-selective lamina I spinal projection neurons. The evidence supporting the authors' claims is convincing, although including a larger sample size and more quantification would have strengthened the study, and the claims of monosynaptic connectivity would benefit from further experimental evidence. The work will interest those in the field of somatosensory biology, especially researchers studying spinal cord dorsal horn circuits and projection neuron cell types.

eLife Assessment

This study offers valuable insights into the anatomical and physiological features of cold-selective lamina I spinal projection neurons. The evidence supporting the authors' claims is convincing, although including a larger sample size and more quantification would have strengthened the study further, and the claims of monosynaptic connectivity would benefit from being stated more cautiously. The work will interest those in the field of somatosensory biology, especially researchers studying spinal cord dorsal horn circuits and projection neuron cell types.

eLife Assessment

This study presents data suggesting that excitatory cholecystokinin (CCK)-expressing neurons in hippocampal area CA3 influence hippocampal-dependent memory using multiple methods to manipulate excitatory CCK-expressing CA3 neurons. The study is valuable, particularly considering that most past studies of CCK-expressing neurons have focused on those neurons that co-express CCK and GABA. Currently, the strength of evidence is incomplete, but it would improve if evidence of specificity was provided and other concerns were addressed. If this is not possible, the conclusions, particularly those requiring evidence of specific targeting of excitatory neurons, should be modified accordingly.

eLife Assessment

Using isolated frog brainstem preparations, pharmacological manipulation of excitability, systematic extracellular unit mapping, and focal microinjections, this study provides important findings on whether the buccal rhythm generator is a discrete anatomical nucleus or a distributed, state-dependent network. The question is conceptually significant and of interest to researchers working within respiratory neurobiology and rhythmogenicity in general, and the preparation and experimental strategy are generally appropriate. However, the evidence for the strongest architectural claims is incomplete, with pseudoreplication in pooled unit-mapping analyses, inconsistent statistical reporting, and limited controls in necessity/sufficiency experiments. Overall, although data are largely convincing, substantial revision and more nuanced interpretation of the results are required before claims of state-dependent architectural reorganization can be considered well-supported.

eLife Assessment

This valuable study addresses a timely question regarding the contribution of transposable elements to splice isoform diversity in the Drosophila brain, directly engaging with recent conflicting findings in the field. The work provides convincing evidence that TE-gene chimeric transcripts are detectable and that prior discrepancies largely arise from methodological differences in computational pipelines and experimental design. The combination of reanalysis, methodological clarification, and targeted validation represents a technical contribution that will be of interest to researchers studying transcriptome complexity and transposable elements. However, the strength of evidence would be further enhanced by increased methodological transparency, more rigorous experimental controls, and a more cautious interpretation of functional implications.

eLife Assessment

This study presents an important methodological advance-Liver-CUBIC combined with multicolor metallic nanoparticle perfusion-that enables high-resolution 3D visualization of the liver's complex multi-ductal architecture. The identification of the Periportal Lamellar Complex (PLC) as a novel perivascular structure with distinct cellular composition and low-permeability characteristics is convincing, supported by rigorous imaging data. The observed scaffolding role during fibrosis offers intriguing biological insights, though the functional claims would benefit from direct experimental validation.

eLife Assessment

This manuscript presents a valuable study of the activity and functional relevance of different circuits in the dentate gyrus of mice performing a pattern separation task. Solid evidence is presented to support the paper's central conclusions. The study is likely to be of interest to those studying the subregional organization and cell type-specific functions of the dentate gyrus.

eLife Assessment

This paper describes Unbend - a new method for measuring and correcting motions in cryo-EM images, with a particular emphasis on more challenging in situ samples such as lamellae and whole cells. The method, which fits a B-spline model using cross-correlation-based local patch alignment of micrograph frames, represents an important tool for the cryo-EM community. The authors elegantly use 2D template matching to provide convincing evidence that Unbend outperforms the previously reported method of Unblur by the same authors. Comparison to alternative programs for motion correction shows smaller gains, but with interesting differences between data sets.

eLife Assessment

This is a valuable study that integrates behavioral and molecular approaches to identify neuromodulators influencing blood-feeding behavior in the disease vector Anopheles stephensi. Through gene expression analyses across blood-seeking life stages and RNA interference experiments, the authors present solid evidence that co-knockdown of the neuromodulators short Neuropeptide F and RYamide affects blood-seeking states in A. stephensi. However, evidence demonstrating that these neuropeptides are sufficient to promote host-seeking is lacking.

eLife Assessment

This study presents valuable findings and employs modern analytical approaches on how transient absence of visual input (darkness) affects tactile encoding in the rat somatosensory cortex (S1). The evidence supporting the authors' claims is solid, as population-level neural activity recorded in S1 and decoded by a CNN carries more discriminable texture information in darkness. The underlying basis of this effect remains only partly resolved, however, because it is still unclear which neural features from the CNN drive the decoding and if visual interference is appropriately accounted for, which might confound true neural representational change.

eLife Assessment

The authors test the hypothesis that gonadal steroid signaling influences the transcriptional development of specific neurons in the mPOA during adolescence, and that such adolescent development of the mPOA is necessary for mating behaviors. The valuable findings are supported by convincing evidence. This work contributes new insight into hormone-sensitive transcriptional profiles within genetically defined neuron clusters in the mPOA during adolescence and will be of interest to systems and molecular neuroscientists and those interested in development, sex differences, and/or hormonal regulation.

eLife Assessment

Using the clownfish model, this study examines how growth, feeding, and agonistic behavior result in socially dominant or subordinate states in size- and age-matched individuals of the clownfish, Amphiprion percula. The authors complement this work with whole-body transcriptomics and find significant variation in genes and gene co-expression modules related to growth and satiety-related pathways, as well as ossification-related genes. They provide solid evidence that emerging dominants grow more, eat more, and behave more aggressively than subordinate or solitary individuals; these phenotypic differences are accompanied by distinct gene expression profiles, including variation in growth- and satiety-related pathways. The work is valuable in advancing our understanding of how the social environment regulates phenotypic change; however, claims regarding the mechanistic role of gene expression are only partially supported by the current analyses.

eLife Assessment

In this important study, Bready et al. investigate how a highly conserved long-range enhancer mediates neural-specific SOX2 regulation during neural differentiation using human neural stem cells. This study has broad appeal to developmental neuroscience; however, the data remain incomplete given the need for homozygous enhancer knockouts and biological replicates in the scRNAseq assays.

eLife Assessment

This fundamental work substantially advances our understanding of short-term plasticity mechanisms by providing evidence for release-independent low-frequency synaptic depression that reflects a redistribution of vesicles within the readily releasable pool, via a reduction in docking site occupancy due to vesicle undocking. The evidence supporting this model is convincing, with rigorous electrophysiological and computational analysis. The work will be of broad interest to cellular neuroscientists and synaptic physiologists.

eLife Assessment

Mechanical transduction channels of sensory hair cells possess lipid scramblase activity. Membrane lipid disruption resulting from mechanical transduction is thought to be restored by flippase activities. This fundamental study provides compelling evidence that ATP8B1, a P4-ATP flippase and its subunit TMEM30B, are key in mediating this restorative function in outer hair cells of the mammalian cochlea.

eLife Assessment

This important study examines the stability and compensatory plasticity in the retinotopic mapping in patients with congenital achromatopsia. It provides convincing evidence for a stable mapping of the visual field in V1, alongside changes of the readout from V1 into V3, which shows revised receptive field location and size. This paper would be of interest to scientists studying the visual system, brain plasticity, and development.

eLife Assessment

This valuable study presents a hierarchical computational model that integrates locomotion, navigation, and learning in Drosophila larvae. The evidence supporting the model is convincing, as it qualitatively replicates empirical behavioral data. While some simplifications in neuromechanical representation and sensory-motor integration are limiting factors, the reported modular framework will be of interest for computational modeling of biological movement and adaptive behavior.

eLife Assessment

This important study combines behavioural psychophysics with image-computable modelling to test whether face recognition relies on view-selective or view-tolerant mechanisms. Although the diagnostic orientation content of faces varies with viewpoint (more horizontal for frontal views, more vertical for profiles), human recognition remains predominantly tuned to horizontal information, consistent with the predictions of a view-tolerant model. The evidence for view-tolerant tuning to horizontal orientations is compelling, although questions remain about the plausibility of the computations implemented in the view-tolerant model and how they map onto mechanisms of everyday face recognition.

eLife Assessment

This Review Article provides a compendium of advice for MD-PhD students to consider when deciding which, if any, clinical field they will select for residency training. It is grounded in published data and effectively considers factors including the potential for clinical disciplines to sustain research integration, provide mentorship, meet lifestyle expectations, and foster a long-term career as a research-focused physician-scientist.

eLife Assessment

This valuable paper provides convincing evidence that humans can navigate better through maps whose local transitions were learned in an intermixed order than maps whose local transitions were learned in neighboring groups. The authors put forward a potential mechanism in which the grouped learning resulted in mental fragmentation, though evidence for this mechanism is incomplete. The work will be of interest to researchers studying cognitive maps and curriculum learning.

eLife Assessment

The authors combined human assembloids, fetal brain tissue, bulk and single cell RNA sequencing, and live imaging to understand the molecular mechanisms affected by hypoxia during cortical development. The findings are very important to the neurodevelopmental field, They reveal new insights into how migration of cortical interneurons can be affected in hypoxic conditions, and provide exciting models to probe broad neurodevelopmental processes in health and disease. The evidence is compelling. The data and analyses are very rigorous and go beyond the state-of-the-art.

eLife Assessment

This valuable study proposes a novel rapid-entry mechanism for Staphylococcus aureus, involving the rapid release of calcium from lysosomes. The paper's strength lies in its very interesting hypothesis. The methods used are solid and adequately support the conclusions.

eLife Assessment

This important study shows that the Nora virus, a natural Drosophila pathogen that also persistently infects many laboratory fly stocks, infects intestinal stem cells (ISCs), leading to a shorter life span and increased sensitivity to intestinal infection with the bacterium Pseudomonas. The authors provide convincing data to support their conclusions. The paper provides new insights into virus-host interactions in the Drosophila gut and serves as a warning for scientists who use the fruit fly as a model to study gut physiology.

eLife Assessment

This valuable study identifies and characterizes probe binding errors in a widely used commercial platform for spatial transcriptomics, discovering that at least 21 out of 280 genes in a human breast cancer panel are not accurately detected. The authors provide convincing evidence for their findings through validation against multiple independent sequencing technologies and reference datasets, and they introduce a computational tool to help predict potential off-target probe binding. Given the broad adoption of this platform in biomedical research, this work provides an essential quality control resource that will improve data interpretation across numerous studies.

eLife Assessment

This important study developed a novel paradigm combined with EEG recordings to examine the neural mechanisms underlying temporal integration in perception and its modulation by prior history (i.e., the serial dependence effect). The results provide solid evidence that two key EEG features, namely the individual alpha frequency and the aperiodic slope, jointly and independently shape perceptual integration and its reliance on prior information. While additional control analyses would further strengthen the main conclusions, the findings will be of broad interest to researchers studying perception, decision-making, inter-individual differences, and brain rhythms.

eLife Assessment

This important study presents convincing evidence that uncovers a novel signaling axis impacting the post-mating response in females of the brown planthopper. The findings open several avenues for testing the molecular and neurobiological mechanisms of mating behavior in insects, and in the revised version the authors provide further evidence supporting their conclusions.

eLife Assessment

This study addresses an important question about how large-scale brain networks interact, and specifically how the default mode network exchanges information with the sensory cortex. The analyses are sophisticated, but at present provide incomplete evidence for the claims made in the paper.

eLife Assessment

This important study addresses a discrepancy between population-level growth laws and single-cell correlations. It shows, for flagellar and synthetic genes in E. coli, that while gene expression of certain genes reduces population-average growth, expression levels positively correlate with growth at the single-cell level. The measurements are mostly convincing, and the proposed mechanism-inheritance of growth factors such as ribosomes during asymmetric division- explains this observation. The theoretical analysis would benefit from clearer explanations and robustness checks.

eLife Assessment

This important study measures single-unit activity in the middle temporal area (MT) of awake-behaving monkeys to test the idea that sensory adaptation contributes to flexible evidence accumulation during decision-making. Solid evidence is provided, showing that adaptation to different temporal contexts shapes both perceptual judgements and neural responses, but analyses aimed at establishing a direct link between them are less persuasive. This work has the potential to be of interest to a broad range of researchers working on visual perception, plasticity, and decision making.

eLife Assessment

The valuable study aims to differentiate between foveal and peripheral attentional mechanisms in visual and frontal brain regions in monkeys engaged in a free-gaze visual search task. The authors interpret differences in responses between target and nontarget conditions as feature-based attention; however, this may not be the correct interpretation. The authors do not provide enough information on how they distinguish foveal and peripheral RFs. Consequently, the study provides only incomplete evidence that does not support the authors' conclusions, and the significance of the findings is not strong.

eLife Assessment

This valuable study introduces a new framework for improving the automated sorting of extracellular action potentials. However, the evidence is incomplete; the biophysical model used for simulation is based on one simulation that does not necessarily reflect real experimental data, the test datasets are insufficiently diverse, and essential algorithmic details are currently missing. This work will be of interest to neuroscientists using high-density multichannel electrophysiology.

eLife Assessment

This valuable study presents a real-time system for identifying multiple unrestrained marmosets in a home cage setting using a combination of face detection and color-coded beads. However, there is incomplete evidence regarding the generalizability and robustness of the system to unconstrained multi-animal environments.

eLife Assessment

This useful study addresses the interesting question of how immune cells recognise infected erythrocytes in malaria. It proposes the parasite protein PfGBP-130 as an interaction partner of the human cell surface protein LFA 1, which could help explain how NK cells recognize infected erythrocytes. The conclusions are partially supported by pull-down and cell-based activation data. However, the overall evidence of direct interaction at the cell-cell interface and downstream effects is incomplete; stronger evidence is required to demonstrate surface exposure of PfGBP-130, as well as a direct role of this antigen in killing.

eLife Assessment

This article presents valuable findings on how the timing of cooling affects the timing of autumn bud set in European beech saplings. The study leverages extensive experimental data and provides an interesting conceptual framework for the various ways in which warming can affect but set timing. The statistical analysis is compelling, but indicates some factors that may temper the authors' claims, while the designs of experiments offer incomplete support for the current claims as they rely on one population under extreme conditions for only one year each while a confounding effect (time in a chamber) sometimes lacks a control.

eLife Assessment

The authors previously identified SLAP as a key suppressor of the Src tyrosine kinase and a tumor suppressor. In this important study, the authors show SLAP functions in a cell-autonomous fashion in colon stem cells and propose solid evidence that SLAP reduces tumorigenesis by inhibiting an EphB2-SRC axis.

eLife Assessment

This study presents an important study of the relationship between morphogen signaling and cell fate choices in the forming zebrafish neural tube, addressing a topical question in developmental biology. The authors provide a solid characterization of the precision limit for gene regulatory networks interpreting Shh, with single-cell resolution and state-of-the-art in vivo approaches. While the depth of analysis is restricted, particularly by the number of cell traces, the study will be of interest to developmental biologists interested in cellular decision-making.

eLife Assessment

In this important study, DNA and RNA are co-imaged in single cells to show that the proximity of topologically associated domain (TAD) boundaries is uncoupled from the transcriptional activity of nearby genes. The evidence supporting these conclusions is convincing for the regions examined, with high-throughput imaging providing robust statistics. This work will be of interest to researchers studying genome architecture and its relationship to gene regulation.

eLife Assessment

The manuscript presents important findings on how C. elegans can utilize distinct molecular mechanisms and circuit engagements to regulate tactile-dependent locomotory behaviours through the AFD thermosensory neuron. The authors use multiple techniques including microfluidics, genetic manipulations and single-copy rescue experiments, to provide compelling evidence for the role of AFD/AIB electrical synaptic connections in this behaviour. The reviewers are satisfied with the comprehensive revisions made by the authors.

eLife Assessment

This important study deepens our understanding of how populations of a given species may diverge in their molecular and physiological patterns as a result of adaptation to different thermal regimes. By approaching this question from multiple directions, the authors provide solid evidence for adaptive changes in three strains of the diamondback moth after only three years of experimental evolution, and support the causal involvement of the PxSODC gene in thermal adaptation to both cold and hot temperatures. This work would benefit from more sophisticated phylogenetic analyses, better statistical support, and a more detailed discussion of the differences in the three strains at the pathway level.

eLife Assessment

This is a potentially important work on the organization of visual information in the rodent superior colliculus. It reports that the selectivity of neurons to line orientation and motion in the visual image is largely governed by the sensitivities of retinal neurons and their ordered projection to the superior colliculus. If confirmed, these conclusions could substantially revise prior thinking in this field. However, in the present state, the methods and analysis are incomplete and cannot justify all the claims.

This important study advances our understanding of the neural substrate of planning trajectories towards a goal by using recurrent neural networks. The manuscript provides solid evidence for most of the claims, but it remains unclear whether the dynamics do indeed bear the defining characteristics of attractors, and the interpretation and scope of some claims may need to be reassessed in light of prior work. The work will be of broad interest to theoretical and systems neuroscientists and to cognitive scientists.

eLife Assessment

This important study presents evidence that the Chromatin-linked adaptor for MSL complex proteins (CLAMP) GA-binding transcription factor (TF) regulates ~75% of HS-induced repression in Drosophila and suggests that CLAMP is the first known transcription factor to induce heat-stress-mediated repression of gene expression. While mechanistic details remain to be sorted out, this manuscript provides convincing evidence that novel pathways involving the CLAMP transcription factor repress gene expression during heat shock stress.

eLife Assessment

This study investigates how the HIV inhibitor lenacapavir influences capsid mechanics and interactions with the nuclear pore complex.

The modeling is technically sophisticated, and the analyses provide solid support for the mechanistic conclusions.

eLife Assessment

In this fundamental work Horne et al present compelling evidence that YbjP is a novel binding partner of the TolC channel protein. The YbjP is characterized using cryo-EM, and its role probed using pull-down experiments, in vivo crosslinking, functional assays along with phylogenetic analysis which are all properly performed and presented and support the main conclusions. While the study does not identify a clear role for this protein, the revised manuscript offers improved clarity and contributes invaluable insight into membrane transport and antimicrobial resistance.

eLife Assessment

This is an important study that takes a key step towards understanding developmental disorders linked to mutations in the O-GlcNAc transferase enzyme by generating a mouse model harboring the C921Y mutation. While the mechanisms remain open, the study thoroughly examines behavioral and anatomical differences in these mice and provides convincing evidence for behavioral hyperactivity and learning/memory deficits, as well as phenotypic differences in skull and brain formation. This study will be of interest to those studying neurodevelopmental disorders and associated mechanisms.

eLife Assessment

This important study presents a compelling link between nutrient signaling and chromosome regulation, demonstrating that reduced activity in a central nutrient-sensing pathway improves chromosome stability and alters gene expression through effects on cohesin. The convincing evidence from a combination of genetic, biochemical and cell biological approaches supports a model in which TORC1-dependent phosphorylation of Mis4 and the cohesin subunit Psm1/Smc1 can modulate cohesin loading to enhance faithful chromosome transmission. While the underlying mechanisms and biological importance of this newly described circuit are not yet fully known, the overall body of evidence is strong and supports the main conclusions.

eLife Assessment

This convincing study examines a novel interaction of RAB5 with VPS34 complex II. Structural data are combined with site-directed mutagenesis, sequence analysis, biochemistry, yeast mutant analysis, and prior data on RAB1-VPS34 and RAB5-VPS34 interactions to provide a new perspective on how RAB GTPases recruit related but distinct VPS34 complexes to different organelles. The judgment is that this work represents a fundamental advance in our understanding of VPS34 localization and regulation.

eLife Assessment

This important study provides compelling evidence that fever-like temperatures enhance the export of Plasmodium falciparum transmembrane proteins, including the cytoadherence protein PfEMP1 and the nutrient channel PSAC, to the red blood cell surface, thereby increasing cytoadhesion. Using rigorous and well-controlled experiments, the authors convincingly demonstrate that this effect results from accelerated protein trafficking rather than changes in protein production or parasite development. These findings significantly advance our understanding of parasite virulence mechanisms and offer insights into how febrile episodes may exacerbate malaria severity.

eLife Assessment

Du et al. present a valuable study examining neural activation in medial prefrontal cortex (mPFC) subpopulations projecting to the basolateral amygdala (BLA) and nucleus accumbens (NAc) during behavioral tasks assessing anxiety, social preference, and social dominance. The strength of the evidence linking in vivo neural physiology to behavioral outcomes was considered solid; however, the electrophysiology data and their interpretation were less well received. Overall, the reviewers felt that the revised work provides insight into how distinct mPFC→BLA and mPFC→NAc pathways influence anxiety, exploration, and social behaviors.

eLife Assessment

This is a detailed and well-designed simulation study of the utility of replication metrics in animal-to-human study translations in bridging the gap between laboratory discoveries and health practice, a critical consideration in turning laboratory scientific research findings into tangible, real-world applications, to directly help human health.

There is some potential for the strength and applicability of the presented evidence to be improved upon revision.

eLife Assessment

The study investigates how CD1c-restricted T cells respond to Mtb-infected APCs, leading to increased cytokine production and cytotoxic activity that may help control Mtb infection. While the work is important and will interest researchers in the field, the supporting evidence is incomplete and could be strengthened by additional experiments. Experiments would: (i) evaluate THP1-CD1c cells to determine whether MHC surface expression is reduced or entirely abolished, (ii) enhance confidence in the purity of the CD1c-specific T cell population isolated from blood, and (iii) suggest what additional signal THP1-CD1c cells treated with Mtb express that is absent from the untreated cells.

eLife Assessment

This study provides valuable findings regarding potential correlates of protection against the African swine fever virus. The evidence supporting the claims is solid, and the results are highly relevant to the field.

The authors provide convincing evidence for the functional roles of the salivary effectors.

eLife Assessment

This study uses a Bayesian framework to characterize latent brain state dynamics associated with memory encoding and performance in children, as measured with functional magnetic resonance imaging. The novelty of the approach offers valuable insights into memory-related brain activity, but the consideration of developmental changes in memory and brain dynamics, and the evidence to support the proposed mapping between specific states and distinct aspects of memory, are incomplete. This work will be of interest to researchers interested in cognitive neuroscience and the development of memory.

eLife Assessment

This important study elucidates the role of the exocyst component EXOC6A at distinct stages of ciliogenesis, which advances our understanding of ciliary membrane remodeling and cilium formation. The authors provide compelling evidence through high quality light and electron microscopic imaging, and careful analysis of knockout cell lines, that EXOC6A interacts with myosin-Va and is dynamically recruited via dynein-, microtubule-, and actin-dependent mechanisms, to support proper formation of the ciliary membrane. The study will be of interest to cell biologists and other researchers interested in vesicular trafficking, organellar membrane dynamics, and ciliogenesis.

eLife Assessment

This fundamental study combines in vitro reconstitution experiments and molecular dynamics simulations to elucidate how membrane lipids are transported from the outer to the inner membrane of mitochondria.

This is a valuable study that provides essential groundwork for the further genetic dissection of dosage-sensitive genes causing metabolic dysregulation in Down Syndrome.

eLife Assessment

The use of DNA tethers is a useful advance for studying how motor proteins respond to load. The authors use a convincing methodology to investigate the detachment and reattachment kinetics of kinesin-1, 2, and 3 motors against loads oriented parallel to the microtubule. As the manuscript stands, the conclusions drawn from the experiments, as well as the overall interpretation of the results, are incompletely supported by the presented data, and the novelty over previous reports appears less clear.

eLife Assessment

The nematode C. elegans is an ideal model in which to achieve the ambitious goal of a genome-wide atlas of protein expression and localization. In this paper, the authors explore the utility of a new and efficient method for labeling proteins with fluorescent tags, evaluating its potential to be the basis for a larger, genome-wide effort that is likely to be very useful for the community. While the evidence for the method itself is solid, carrying out this project at a large scale will require significant additional feasibility studies.

eLife Assessment

This important study reports that genome-wide signatures of relaxed purifying selection in genes associated with male fertility may reflect an evolutionary response to reduced sperm competition in the gorilla mating system.

eLife Assessment

The authors use a convincing methodology to investigate the detachment and reattachment kinetics of kinesin-1, 2, and 3 motors against loads oriented parallel to the microtubule. The findings are useful to the field in providing a clearer view of kinesin function under load. However, as the manuscript stands, the conclusions drawn from the experiments, as well as the overall interpretation of the results, are only partially supported by the presented data, and the novelty relative to previous reports appears less clear.

eLife Assessment

This important study demonstrates the power of the UniDesign computational framework in prospectively engineering a PAM-relaxed Staphylococcus aureus Cas9 variant with editing performance comparable to evolution-derived counterparts. The authors provide convincing evidence through rigorous biochemical validation across multiple human cell types, comprehensive deep-sequencing analyses, and direct comparisons with established variants, providing mechanistic insights into PAM specificity remodeling and Cas9 optimization. By establishing computational design as a viable alternative to directed evolution for CRISPR systems, this work will be of broad interest to the protein engineering, genome engineering, synthetic biology, and computational protein design communities.

eLife Assessment

The authors provide valuable data linking NAD+ dependent HSD3b6 gene expression in the eyelid to a vicious cycle involving decreased steroidogenesis and AR signaling, pro-inflammatory cytokine release, inflammation, CD38 activation, and further NAD+ decline, which induces meibomian gland atrophy leading to dry eye disease. Overall, the presented work provides evidence for the pathologic relationship between a pro-inflammatory environment, intracrine activity, and the NAD+ cofactor. However, the current study does not clearly establish the proposed intracrine mechanism and may largely reflect systemic hormonal effects resulting from the global Had3b6 knockout, leading to an incomplete narrative.

Editors Assessment:

In this new methodological work researchers investigate the genetic structure and admixture patterns among dog breeds through a comprehensive analysis using whole genome sequencing data. A reference population was established comprising 349 individuals across 65 breeds, from which breed-informative single nucleotide polymorphisms (SNPs) were derived. Using the SCOPE algorithm previously employed in many global ancestry studies to estimate admixture proportions effectively, this demonstrated strong accuracy even at low sequencing depths (<1x). After peer review suggested changes to data processing the work was suitably solid to make some interesting findings using this approach. Results indicate that specific breeds, such as Catahoula Leopard Dogs and Greek Tracers, present unique challenges in admixture inference due to their genetic proximity to other breeds. With challenges in estimating Pit Bull Terrier ancestry/admixture, suggesting that there could be several genotypes associated with the Pit Bull Terrier breed . The methods provide a robust framework for future assessments of canine genetic diversity and health implications in canid populations. And processed reference population data is also available in the Github repository for reuse.

eLife Assessment

This study provides valuable insights into aged muscle stem cell biology by revealing phenotypic and functional heterogeneity within the geriatric MuSC pool and proposing a VCam-low/negative subpopulation that may account for the reported decline in MuSC numbers with age. These findings have implications for understanding aging-related changes in stem cell maintenance and for improving strategies to isolate or rejuvenate aged MuSCs. However, the evidence supporting the main claims is incomplete, key analyses such as absolute MuSC quantification, fate assessment of VCam-low/negative cells, inclusion of standard aged cohorts, and validation of proposed surface markers are still needed to confirm that overall MuSC abundance is maintained and that a distinct subpopulation has been identified.

eLife Assessment

This study illustrates a valuable application of BID-seq to bacterial RNA, allowing transcriptome-wide mapping of pseudouridine modifications across various bacterial species. The evidence presented includes solid data and analyses that would benefit from additional experimental validation. The work will interest a specialized audience involved in RNA biology.

eLife Assessment

The study curated a set of Liver X receptor ligands that may guide the design of future drugs that activate the Liver X receptor as potential therapeutics for cardiovascular disease, Alzheimer's and type 2 diabetes, without inducing mechanisms that promote fat/lipid production. The authors also present improved multiplexed precision CRT (coregulator TR-FRET) and cellular assays which allows measurement of ligand potencies to displace corepressors in the presence of coactivators, which cannot be achieved in a regular CRT assay. This makes the evidence presented compelling as it stretches beyond the current state-of-the-art, and these important findings are expected to have practical implications in many sub-fields and remain of interest to scientists working in cell and molecular biology, drug discovery, medicinal chemistry and pharmacology.

eLife Assessment

This study presents results supporting a model that tumorous germline stem cells (GSCs) in the Drosophila ovary mimic the stem cell niche and inhibit the differentiation of neighboring cells. The valuable findings show that GSC tumors often contain non-mutant cells whose differentiation is suppressed by the GSC tumorous cells. However, the evidence showing that the GSC tumors produce BMP ligands to suppress differentiation of non-mutant cells is incomplete due to concerns about the new HCR data.

eLife Assessment

The manuscript concerns a fundamental and controversial question in Trypanosoma brucei biology and the parasite life cycle, providing further evidence that slender bloodstream forms can indeed infect Tsetse flies. The study is solid in design and execution, and addresses several criticisms made of the authors' earlier work. Nevertheless, some of the main conclusions are only partially supported: one issue is how, precisely, a "slender" bloodstream form is defined, and discrepancies with some results from other laboratories remain unexplained.

eLife Assessment

This study provides a valuable contribution to the field of zebrafish immunology by demonstrating that the two TNF paralogs tnfa and tnfb show distinct cellular sources and temporal expression patterns during inflammation. These findings are potentially significant because they suggest regulatory divergence and functional specialization within the TNF signaling system in teleosts. While the evidence supporting differential expression is convincing, the work remains largely observational and would benefit from functional experiments and deeper mechanistic insight to determine whether these differences translate into distinct roles in inflammatory signaling. This work will be of interest to immunologists interested in inflammatory cytokine evolution and immune regulation in vertebrates.

eLife assessment

The study provides an important advance towards understanding how spatial and temporal transcriptional programs are integrated to regulate lineage-specific chromatin and enhancer activation. The functional evidence is currently incomplete, but the current data provide a solid correlative and conceptual foundation. Functional experiments directly linking Gsb occupancy to chromatin state and regulation of some lineage-specific targets would further strengthen the causal interpretation of the model. Clarifying the scope of conclusions and explicitly acknowledging the technical limitations of current chromatin assays would provide a more balanced interpretation of the manuscript.

eLife assessment:

This important study presents a novel and technically robust framework that combines deep learning and optimized patch‑clamp protocols to infer biophysical parameters and generate electrophysiology‑based digital twins, with the inclusion of convincing experimental data being a clear strength; there is methodological innovation and potential impact for understanding cellular heterogeneity, drug response, and arrhythmia risk prediction. Concerns remain about clarity and validation, particularly regarding the biological meaning of the modeled heterogeneity, the selection and sufficiency of large synthetic training populations, and the robustness and uniqueness of inferred parameter sets. Most notably, key translational claims (e.g., replacing large‑scale wet experiments and predicting rare arrhythmic events) lack direct experimental validation and head‑to‑head comparisons with conventional protocols. Overall, while the approach is promising and timely, stronger biological grounding, clearer framing, and additional experimental validation are needed to support the manuscript's broad claims.

eLife Assessment

This important study by Mattenburger et al. employs structural biology, biochemistry, and genetics to advance understanding of how bacteriophage contractile injection systems mediate host recognition and DNA delivery, yielding a remarkable 1.15 A crystal structure of the T4 spike tip complex (gp5-gp5.4). The compelling evidence presented demonstrates that the spike tip protein gp5.4 is essential for phage fitness and successful infection of Escherichia coli strains bearing truncated lipopolysaccharide; however, direct proof regarding interaction with the cell wall or its components is lacking. The study further provides biochemical evidence that the analogous spike tip protein from phage P2 (GpV) is translocated into the host periplasm during infection, together establishing the spike tip as a critical and active component of the phage infection machinery.

eLife Assessment

In their study, Brown et. al. provide an important advance in understanding the architecture of the mycobacterial outer membrane. Using all-atom simulations of model mycomembranes, the work reports compelling structural insights into how α-mycolic acids and outer leaflet lipids (PDIM and PAT) shape membrane organisation. The work revealed membrane heterogeneity with ordered inner leaflets and disordered outer leaflets that provide a molecular explanation for the resilience of the mycobacterial envelope.

eLife Assessment

This important study introduces an innovative synthetic nanobody approach to probe the function of the bacterial SMC complex.

eLife Assessment

This paper's biochemical studies of the mechanisms underlying paradoxical activation of RAF family kinases by small-molecule inhibitors have uncovered some important new features of this process by establishing a role for the N-terminal acidic (NtA) motif and showing that CRAF and ARAF can also exhibit paradoxical activation. However, there are substantial criticisms that can be made regarding the data analysis and the evidence for the authors' new model that paradoxical activation does not rely on negative allostery is considered incomplete.

eLife Assessment

This important study presents a convincing methodological approach to probe the structural features of the full-length human Hv1 channel as a purified protein. The method is supported by rigorous biochemical assays and spectral FRET analysis, which will interest biophysicists and physiologists studying Hv1 and other ion channels and membrane proteins. Overall, the work introduces an interesting labeling strategy and provides a methodology that is of value in investigating hHV1 in particular and can be extended to other ion channels. The authors also provide preliminary observations regarding conformational changes induced by zinc.

This is an important study that addresses the temporal aspects of cell non-autonomous regulation of lifespan. It demonstrates that the same neurons and neurotransmitter have distinct impacts on longevity at different ages. The data convincingly supports the authors' claims.

eLife Assessment

In this valuable study, the authors examine transcription and chromatin dynamics during early zebrafish development by simultaneously profiling histone modifications and full-length transcriptomes in thousands of single cells, providing solid analysis that chromatin and transcriptional states are initially weakly correlated in early embryonic cells and become progressively more aligned as differentiation proceeds. The work also supports a model in which promoter-anchored cis-spreading of H3K27me3 contributes to stable gene silencing during development. Future functional perturbations and orthogonal validations will be needed to determine the causal contribution of Polycomb spreading to fate commitment. Overall, the dataset and accompanying analyses provide a robust resource and a quantitative framework for studying chromatin-transcription relationships during vertebrate embryogenesis.
