    1. eLife assessment

      This valuable study poses a provocative mechanism of channel activation of the mechanically activated ion channel TREK-1. The data provide evidence that the application of shear to cells causes a redistribution of both TREK-1 and an associated enzyme, PhospholipaseD2 in the membrane that increases the enzyme activity. The work offers a new mechanism; however, evidence is incomplete and restricted to the over-expression system used.

    1. eLife assessment

      The aim of this valuable study is to identify novel genes involved in sleep regulation and memory consolidation. It combines transcriptomic approaches following memory induction with measurements of sleep and memory to discover molecular pathways underlying these interlinked behaviors. The authors explore transcriptional changes in specific mushroom body neurons and suggest roles for two genes involved in RNA processing, Polr1F, and Regnase-1, in the regulation of sleep and memory. At present, the strength of the evidence is incomplete to support the main claim that these two genes establish a definitive link between sleep and memory consolidation.

The paper will be of interest to those working in the field of clinical neuroscience.

    1. eLife assessment

      This article describes a useful python-based image-analysis tool for bacteria growing in the 'mother-machine' microfluidic device. This new method for image segmentation and tracking offers a user-friendly graphical interface based on the previously developed, promising environment for image analysis 'Napari'. The authors demonstrate the usefulness of their software and its robust performance by comparing it to other methods used for the same purpose. The comparison provides solid support for the new method, although it would have been even stronger if tested using data sets from other groups. This article will be of interest for scientists who utilize the 'mother machine', not least because it also provides a short overview of how to set up this widely used device.

    1. eLife assessment

      This manuscript presents valuable findings about how sphingolipids and membrane contact sites are involved in promoting vacuole fission in S. cerevisiae. While a connection between the levels of sphingolipids and vacuole homeostasis is interesting, the data pertaining to this issue are incomplete and do not fully support the claim for causality between altered lipid composition and organelle dynamics. The work will be of interest to cell biologists working on organelle biogenesis and lipid metabolism.

    1. eLife assessment

      In this important study, the rabbit was used as a non-rodent mammalian model to show that DMRT1 has a testicular promoting function as it does in humans. The experiments are meticulous and compelling, and the arguments are clear and convincing. These results may explain the gonadal dysgenesis associated with mutations in the DMRT1 locus in humans and highlight the need for mammalian models other than mice to better understand the process of gonadal sex determination in humans.

    1. eLife assessment

      In this valuable manuscript, the authors attempt to examine the role of long non-coding RNAs (lncRNAs) in human evolution, through a set of population genetics and functional genomics analyses that leverage existing datasets and tools. Although the methods are at times inadequate - for example, suitable methods and/or relevant controls are lacking at many points, and selection is inferred sometimes too quickly - the results nonetheless point towards a possible contribution of long non-coding RNAs to the evolution of human biology and they suggest clear directions for future, more rigorous study.

    1. eLife assessment

      This paper reports important findings on a potent activator of the YAP pathway, demonstrating its mechanism through alternative splicing changes. The authors provide convincing evidence to support their claims, although more consistent inhibitor concentrations would have strengthened the study. This research is of interest to biologists studying alternative splicing or the Hippo pathway, with significant implications for medical research.

    1. eLife assessment

      This study adds a valuable new perspective to a long-standing question: What controls the repair of photosystem II (PSII), a key process in maintaining and optimizing photosynthesis? The work supports a role for chemical modification in the recognition and subsequent degradation of a key protein subunit of PSII by a bacterial-type protease, suggesting that tryptophan oxidation of components of the photosynthetic apparatus after high light stress plays a critical role in initiating the PSII repair system. The evidence supporting the authors' conclusions is solid, although their arguments would be strengthened by additional experiments.

    1. eLife assessment

      This study provides valuable insights into the dynamic interplay between the starvation and hyper-osmotic stress responses in budding yeast, where the presence of one stress can impact the concurrent effects of another perturbation. Using microfluidic devices and extensive quantitative analyses of time-series responses, the authors applied concurrent (in-phase) or alternate (anti-phase) stresses. Their compelling analyses reveal some unexpected behaviors that could not have been guessed from simpler experimental designs, revealing that investigating complex environmental inputs can reveal new biological insights, even for well-studied systems.

    1. eLife assessment

      Cryo-EM has become the dominant method in structural biochemistry, and making more efficient use of expensive microscope time is therefore of broad interest to academic and industrial users. The authors identify a bottleneck in cryoEM data collection, namely path optimization, and provide a valuable machine-learning model to overcome this bottleneck. The solid data presented suggests their model can replace a human operator to automate efficient data collection.

    1. eLife assessment

      This study is of fundamental significance, providing compelling data on the mechanism by which ULK4 regulates the transcription factor GLI2 and on the ULK4/STK36 interaction promoting GLI2 phosphorylation and activation of the sonic hedgehog (SSH) pathway. The work will be of interest to cell biologists and the signaling community in general.

    1. eLife assessment

      This study presents valuable findings showing the contrasting responses of two bacteria to the phytoplankton-derived compound azelaic acid. Metabolomic and transcriptomic data provide convincing evidence for activation of the assimilation pathway in one marine bacterial species and a stress response in another species. There is also solid evidence for azelaic acid altering marine microbial community structure in mesocosm experiments, but the underlying community-level mechanisms are not investigated in this study.

    1. eLife assessment

      In this important paper, the authors report a link between brumation and tissue size in frogs, summarizing convincing evidence that extended brumation is associated with smaller brain size and increased investment in reproduction-related tissues. The research will be of broad interest to ecologists, evolutionary biologists, and those interested in global change biology. While the dataset involves significant field work and advanced statistical analyses, the manuscript would benefit from more explanation of the models, including why frogs are a good model in which to address these questions, and from general improvement in the structure and conciseness.

    1. eLife assessment

      This valuable study presents findings on the mode of action of MOTS-c (mitochondrial open reading frame from the twelve S rRNA type-c), and its impact on monocyte-derived macrophages. The authors present solid evidence for its increased expression in stimulated monocytes/macrophages, its direct bactericidal functions, as well as its role in the modulation of monocyte differentiation into macrophages. Since most of the data were generated from a cell line (THP1), future work is required to validate observations in primary cells and to further support the claims of this work.

    1. eLife assessment

      In this intriguing study, the authors offer a new metric, Codon Adaptation Index of Species (CAIS), which allows one to determine the strength of selection and effective population sizes using data on GC content and amino acid composition. This could be of broad use in molecular evolution, as it could be applied across species. The study offers important findings that may aid in our ability to compute key population genomic parameters from genomic data, and the conclusions are based on solid evidence.

    1. eLife assessment

      This important study addresses both the native role of the Plasmodium falciparum protein PfFKBP35 and whether this protein is the target of FK506, an immunosuppressant with antiplasmodial activity. The demonstration of the essentiality of FKBP35 in parasite growth relies on compelling genetic evidence. However, it remains unclear whether FK506 exerts its antimalarial activity through an FKBP35-independent mechanism.

    1. eLife assessment

      The adaptation of organs including the heart to chronic stress has interested biologists for a long time. Using an elegant model of overexpression of adenyly cyclase, the authors demonstrate posttranslational modification of the protein by phosphorylation, making an important contribution to approaches for the protection of heart performance in these transgenic mice. The convincing results open a new paradigm in understanding the biological effects of stress.

    1. eLife assessment

      This important study shows that a splice variant of the kainate receptor Glu1-1a that inserts 15 amino acids in the extracellular N-terminal region substantially changes the channel's desensitization properties, the sensitivity to glutamate and kainate, and the effects of modulatory Neto proteins. The functional data supporting the role of the 15 amino acid insert are solid, although some clarifications and more data are needed to determine the molecular mechanism by which the insert changes the functional profile of the channel. Even so, these findings substantially advance our understanding of splice variants among glutamate receptors and will be of interest to neuro- and cell-biologists and biophysicists in the field.

      This valuable study provides a comparative interactome analysis of α-arrestin in human and Drosophila. Using convincing methodology that includes affinity purification/mass spectrometry, bioinformatic tools and experimental data in human cells, the authors identify biological roles of protein-protein interactions (PPI) involving α-arrestin in the two species. This study will serve as a broadly relevant resource for understanding the PPI network of human and Drosophila α-arrestins.

    1. eLife assessment

      Using a newly developed C. elegans model of Alzheimer's disease that expresses Abeta aggregates extracellularly, the authors provide convincing evidence of a disintegrin and an ortholog of human ADAM9 that participate in removing these extracellular aggregates. The worm model presented in this important paper may be very useful to the Alzheimer Disease field.

    1. eLife assessment

      This important paper reveals distinct dynamics of two meiosis-specific cohesin complexes containing either REC-8 or CHO-3/4 in C. elegans: REC-8-cohesin is essential for sister chromatid cohesion in meiosis I and DNA double-strand break repair, while COH-3/4-cohesin, whose binding to meiotic chromosomes is stabilized by the cohesin accessory protein SCC-2, is necessary for loop-axis formation. The experimental evidence in the paper is solid based on cytological analysis using a conditional depletion of the gene. The work will be of interest to researchers working on meiosis and chromosome dynamics.

    1. eLife assessment

      This important manuscript, which describes the largest genetic association study to date, uses broadly compelling methods to address the genetic susceptibility to tuberculosis infection. A strength of the paper is that this multi-ancestry meta-analysis of genetic association studies than is more powerful than what has been done before. A weakness is that its main result is difficult to interpret due to the complexity of the genetic association signal.

    1. eLife assessment

      This is an important study on learning strategy differences in autism vs typically developing controls. The study identifies similar learning rates but different learning strategies. The evidence provided by the authors is convincing, relying on well-done tasks and fMRI analyses.

    1. eLife assessment

      This important work provides evidence regarding the impact of the COVID-19 pandemic on cervical cancer screening and precancer treatments in the USA. As there are few screening registries, the study provides solid evidence using a survey of health providers' impressions to assess whether cervical cancer screening services declined during the pandemic. The work will be of interest to public health professionals working in cancer prevention.

    1. eLife assessment

      Salmonella invades and survives in host cells via SPI-1 and SPI-2 type III secretion system mechanisms, with the SPI-2 system allowing for intracellular survival in Salmonella-containing vacuoles, which have a low-pH environment. Transcription of SPI-2 genes at low pH is activated by the DNA-binding SsrB protein, which sits at the top of the SPI-2 regulatory hierarchy. This study provides important insights as to how SsrB is allosterically affected by pH resulting in acid-dependent DNA binding. However, there are concerns about some experiments, and the evidence presented is not fully conclusive.

    1. eLife assessment

      This paper reports the fundamental discovery of adrenergic modulation of spontaneous firing through the inhibition of the Na+ leak channel NALCN in cartwheel cells in the dorsal cochlear nucleus. This study provides unequivocal evidence that the activation of alpha-2 adrenergic or GABA-B receptors inhibit NALCN currents to reduce neuronal excitability. The evidence supporting the conclusions is compelling, the electrophysiological data is high quality and the experimental design is rigorous.

    1. eLife assessment

      In this useful study, the authors explore regulatory cascades governing mammalian cochlear hair cell development and survival. They confirm previous studies that the transcription factors Pou4f3 and Gfi1 are necessary for hair cell survival, and use compelling evidence to demonstrate that the RNA binding protein gene RBM24 is regulated by Pou4f3, but not Gfi1. These findings will be of interest to those working on hearing loss, and hold significance for viral gene delivery methods aiming to manipulate gene expression.

    1. eLife assessment

      In zebrafish, primary motor neurons (PMNs) control escape movements, and a more heterogeneous population of secondary motor neurons (SMNs) regulate the speed of rhythmic swimming. Using single cell RNA sequencing (scRNAseq), the authors have obtained convincing evidence that PMNs, and two types of interneurons innervating them, express a set of three genes encoding voltage-gated ion channels enabling rapid firing. The PMNs also express high transcript levels of proteins involved in exocytosis, which would be expected to support rapid neurotransmitter release. These results will be important for those working on spinal cord function and zebrafish genomics/transcriptomics.

    1. eLife assessment

      This article presents important results describing how the gathering, integration, and broadcasting of information in the brain changes when consciousness is lost either through anesthesia or injury. They provide convincing evidence to support their conclusions, although the paper relies on a single analysis tool (partial information decomposition) and could benefit from a clearer explication of its conceptual basis, methodology, and results. The work will be of interest to both neuroscientists and clinicians interested in fundamental and clinical aspects of consciousness.

    1. eLife assessment

      This study provides valuable insights into how the brain parses the syntactic structure of a spoken sentence. A unique contribution of the work is to use a large language model to quantify how the mental representation of syntactic structure updates as a sentence unfolds in time. Solid evidence is provided that distributive cortical networks are engaged for incremental parsing of a sentence, although the contribution could be further strengthened if the authors would further highlight the main results and clarify the benefit of using a large language model.

    1. eLife assessment

      This paper describes important advances from the results of studies on atypical language lateralisation and how this might impact language behaviour, as well as its associations with reading skills and the prevalence of schizotypy and autistic traits. Despite most of the conclusions of this paper being supported by evidence, several aspects including the characteristics of participants tested, hypotheses/predictions, and data analysis, are incomplete and/or need some clarification. The work has implications for evolutionary hypotheses and our understanding of the effects of brain damage on distinct cognitive functions.

    1. eLife assessment

      This fundamental work substantially advances our understanding of retinol transport through the blood-brain barrier.

    1. eLife assessment

      This valuable study provides a comprehensive assessment of cell-free DNA methylation to explore the ability of a newly-developed so-called "multimodal" predictive model in detecting malignancies and discriminating tumor of origin. The strength of evidence is solid and the logic beneath this study is well-organized. The study sheds insights into the early detection of malignancies with noninvasive methods using a large sample size with external validation cohort. This study will be of interest to cancer geneticists and oncologists for early diagnosis of cancer.

    1. eLife assessment

      This important study advances our understanding of the ways in which different types of communication signals differentially affect mouse behaviors and amygdala cholinergic/dopaminergic neuromodulation. Researchers interested in the complex interaction between prior experience, sex, behavior, hormonal status, and neuromodulation should benefit from this study. Nevertheless, the data analysis is incomplete at this stage, requiring additional analysis and description, justification, and - potentially - power to support the conclusions fully. With the analytical part strengthened, this paper will be of interest to neuroscientists and ethologists.

    1. eLife assessment

      This study provides a valuable tool for predicting binding between immune cells receptors and antigens based on protein sequence data. Its improvement over existing methods is supported by solid analysis, though more details on data, architectures and benchmarking are needed to fully justify this claim. This study will be of interest to immunologists and computational biologists.

    1. eLife assessment

      In Drosophila melanogater, the Store-operated Ca2+ entry (SOCE) channel, Orai, is required for the development of flight-promoting dopaminergic neurons. Here, Mitra et al. determine that expression of a loss-of-function Orai1 mutant during the 72-96 hour window of pupal development impairs gene expression in dopaminergic flight neurons in part through the expression of Set2, a histone methyltransferase. The authors identify a large number of genes that are controlled by Set2, and show that Set2 is controlled by the trl transcription factor. Although the findings reported here are important, the evidence supporting some of the claims is incomplete.

    1. eLife assessment

      This manuscript supports the intriguing idea that some aspects of novel learning can occur during sleep and outside of awareness. The authors provide solid evidence that presenting participants with novel words and their translations during sleep, especially during slow oscillation troughs, leads to the ability to categorize the semantic meaning of those words during awake testing 36 hours later. These findings represent a valuable contribution to the literature on unconscious processing and learning during sleep, although the claim that the results reflect episodic memory formation, in particular, deviates from typical use of this term in the literature.

    1. eLife assessment

      In this manuscript, Chakraborty et al address the role of IP3R1 in regulating store-operated calcium entry in neurons and neural progenitors. Long-standing observations in non-neuronal cells have shown that IP3Rs are not required for SOCE. In contrast to those findings, this manuscript determines that in neuronal cells, knockdown of IP3R1 suppresses SOCE by disrupting ER-plasma membrane contact sites. The paper supports a novel role for IP3R1 as a tether in promoting membrane contact sites which would have broad implications for a range of physiological processes including SOCE and lipid metabolism.

    1. eLife assessment

      This study reports valuable behavioral and computational observations regarding how passive exposure to auditory stimuli can facilitate auditory categorization. The combination of behavioral results in mice with a study of artificial neural network models provides solid evidence for the authors' conclusions. This paper will likely be of broad interest to the general neuroscience community.

    1. eLife assessment

      This is an important study on the role of the Ras/MEK/Erk signaling cascade in brain development, with both theoretical and practical implications in multiple fields. The authors reveal functional redundancy and shared function for Erk1 and Erk2 in determining medial ganglionic eminence derived glial number, and exclude a role for Erk1 and Erk2 in the regulation of GABAergic neuron number or initial specification of GABAergic identity. They combine multiple methods including Ribotags, electrophysiology, and chemogenetic stimulation using DREADDs towards comprehensive conclusions. Reviewers expressed concerns about the coherence of the findings, and about the selection of controls mouse lines. Heterozygous ERK1/2 mice are used as 'het controls' throughout the manuscript, however, reviewers felt that there was not sufficient evidence that ERK levels in heterozygous mice are similar to wildtype mice. Nevertheless, these compelling findings will be of interest to a broad readership, and especially readers interested in kinase function and neurodevelopmental syndromes.

    1. eLife assessment

      The work examines the effect of transcranial alternating current stimulation on the perception of specific features in sound: gaps in a frequency modulated noise. Several theories link the phase of brain oscillations to perception: the work is important in suggesting direct support for the link. The work is technically well executed on a good size cohort. Still one reviewer raised concerns that the effect seen might be an artifact of the analysis used, so the strength of evidence is incomplete at this stage . We encourage the authors to respond to this issue.

    1. eLife assessment

      fMRI was used to address an important aspect of human cognition - the capacity for structured representations and symbolic processing - in a cross-species comparison with non-human primates (macaques); the experimental design probed implicit symbolic processing through reversal of learned stimulus pairs. The authors present solid evidence in humans that helps elucidate the role of brain networks in symbolic processing, however the evidence from macaques was incomplete (e.g., sample size constraints, potential and hard-to-quantify differences in attention allocation, motivation, and lived experience between species).

    1. eLife assessment

    1. eLife assessment

      This valuable study provides solid evidence that the stability and function of the Eph-B2 receptor (EPHB2) are affected by interactions with the multifunctional MYCBP2 and Fbxo45 proteins, extending our knowledge of how members of this key family of receptors are regulated, in particular in regard to their forward signaling. The biochemical binding evidence is generally convincing, but the evidence from the C. elegans experiments is still incomplete.

This work will be of interest to computational and molecular biologists working on transcription factors.

    1. eLife assessment

      This valuable study combines in vitro experiments with simulations to identify the mechanisms governing modulation of microtubule dynamics by GTP hydrolysis. The authors introduce a solid new approach by using a mixed GDP/GMPCPP lattice and varying GDP concentration to reveal that the nucleotide at the interface of two tubulin dimers determines the strength of the interaction between two dimers. Overall, the findings will be of interest to biophysicists and cell biologists, especially in the field of microtubule biology.

    1. eLife assessment

      This study presents a valuable finding on the optimal prioritization in different malaria transmission settings for the distribution of insecticide-treated nets to reduce the malaria burden. The evidence supporting the claims of the authors is solid, although the authors have made various simplifications to enable the identification of optimal strategies. The work will be of interest from a global funder perspective, though somewhat less relevant for individual countries.

    1. eLife assessment

      This is important work analyzing the trial-by-trial progression of learning, and how the outcome of one trial influences cortex-wide neural responses on the next trial. However, the evidence for the central claims is incomplete because the potential confounds of slow hemodynamic effects and behavioral changes induced by the previous trial were not adequately addressed.

    1. eLife assessment

      In this paper, the authors demonstrate an interesting link between mitofusin function (MFN2) and PARKIN recruitment and mitophagy, underlying cardiomyopathy. This is a valuable finding with broad implications for understanding the mitochondrial biology as well as mechanisms involved in heart pathologies. However, the analyses are incomplete and the main conclusions are only partially supported and need to be further evidenced.

    1. eLife assessment

      This useful manuscript describes the TOR signaling pathway in the human and plant pathogen Aspergillus flavus. While the authors provide a large amount of descriptive and often confirmative data, the evidence for the new claims made here for the TOR pathway in this species is incomplete.

    1. eLife assessment

      How the genome is folded three dimensionally is thought to control gene regulatory pathways during critical processes such as cellular differentiation. Using multiple assays, the authors of this important study probe topologically associated domains (TADs) and report involvement of a protein arginine methyltransferase 5 in chromatin organization and transcriptional regulation. The data gathered are generally solid and broadly support the role of this protein in organization of the adipocytic lineage, but additional control experiments would make the inferences stronger.

    1. eLife assessment

      This useful study emphasizes some previously ignored aspects of synaptic communication between Purkinje neurons and their targets in the cerebellar nuclei. Reviewers felt that some aspects of the evidence were solid but that others were incomplete.

    1. eLife assessment

      This manuscript compiles existing algorithms into an open-source software package that enables real-time motor unit decomposition from muscle activity collected via grids of surface electrodes and indwelling electrode arrays. The software package is valuable given that many motor neuroscience labs are using such algorithms and that there exist a host of potential real-time applications for such data. Validation of the software package is generally solid but incomplete in some significant areas: the primary data is narrow in scope and only from male participants, and there is a lack of ground truth tests on synthetic data. The impact of the software package could be strengthened by making it less tied to specific electrode hardware and by expanding it to easily permit offline analysis.

    1. eLife assessment

      This valuable study presents a large experimental study to examine the effects of plant species richness, plant genotypic richness, and soil water availability on herbivory patterns on Piper species in several tropical sites. The authors find that water availability and both intra- and interspecific plant diversity influence herbivory and herbivore diversity, but that the effects differ in significant ways across sites. The major weakness lies in findings that can be better presented in a less complicated fashion. The major claims are currently supported by a combination of solid and incomplete evidence, and the manuscript would benefit from better organization.

    1. eLife assessment

      The authors have used a 'digital twin' strategy to recapitulate human pathophysiology of arrhythmia. These important findings have theoretical and practical implications beyond the single subfield of cardiovascular science for personalised medicine. The experimental design relies on state-of-the-art methodologies, with compelling results. The work will be of broad interest to colleagues in the general area of computational biology.

    1. eLife assessment

      This study by Chiu and colleagues is an important contribution to the study of the circuitry of aggressive behaviours and of mechanisms that generate persistent states. The data ruling out current ideas in the field are convincing.

    1. eLife assessment

      This valuable study considers the relationship between performance in a path-integration-based navigation task and the degree to which medial entorhinal grid cells encode the animal's position. Using a virtual reality environment combined with neural recordings, the work presents solid evidence that the variability in the spatial firing of grid cells correlates with the behavioral performance of the mouse on the navigational task.

    1. eLife assessment

      The authors tested the hypothesis that age-dependent factors in human sera affect the core circadian clock or its outputs in cultured fibroblasts. While the paper does not provide molecular mechanistic insight how sera from young versus old donors lead to differences in cyclic gene expression, it does provide fundamental insights and a possible explanation for previous observations showing that circadian gene expression in peripheral tissues tend to dampened or phase-shift with age. As presented, the strength of the evidence is, however, incomplete.

    1. eLife assessment

      This study provides important new insights into the structural diversity of effectors - proteins secreted by pathogens and symbionts into host cells - from the plant-associated fungus Fusarium oxysporum f. sp. lycopersici. The study provides a convincing approach to understand how effectors navigate their host environment using both computational and experimental approaches to understand how their structure influences binding partners. The work will be of interest to those studying molecular host-microbe interactions and disease protection.

    1. eLife assessment

      This valuable study presents findings on how the hypoxia response pathway senses and responds to changes in the homeostasis of the amino acid cysteine and other sulfur-containing molecules, with compelling and rigorous genetic analyses. The works adds to a growing body of literature showing that prolyl hydroxylation is not the only mechanism by which the hypoxia response pathway can act. Although the paper does not reveal new biochemical insight into the mechanism, it opens up new areas of investigation that will be of interest to cell biologists and biomedical researchers studying the many pathologies involving hypoxia and/or cysteine metabolism.

      By developing a novel method for detecting genetic variants associated with germline mutation spectrum variation, this important study identifies a new "mutator" locus in a population of inbred mouse strains, although the causal gene(s) within this locus remains uncertain. The authors further demonstrate that this new mutator locus interacts epistatically with a previously identified mutator allele on C>A mutation rate, showcasing the complexity of the genetic basis underlying variation in mutation rate and spectrum. Evidence for major findings in this paper is convincing, but the power, statistical properties and limitations of the new method need to be further characterized to support its broader applicability to other systems.

      In this useful study, a solid machine learning approach based on a broad set of systems to predict the R2 relaxation rates of residues in intrinsically disordered proteins (IDPs) is described. The ability to predict the patterns of R2 will be helpful to guide experimental studies of IDPs. A potential weakness is that the predicted R2 values may include both fast and slow motions, thus the predictions provide only limited new physical insights into the nature of the relevant protein dynamics.

      In this valuable report, the authors explore the connection between mTORC signaling and APA regulated by the CFIm complex. Using a combination of genetic and functional genomics approaches, the study reveals that a twin UGUA motif is a potent cis acting regulation of PAS usage that is recognized by CFIm. Overall, the evidence in general is convincing and supports the conclusions and provides the field with additional mechanistic insight of how signaling connects to APA regulatory machinery.

    1. eLife assessment

      This is an important study of the dimensionality and synchrony of calcium responses in Purkinje cells measured across a large region of the cerebellar cortex over the course of learning. This work has the potential to inform our understanding of the functional organization of the cerebellum and longstanding hypotheses about the role of cerebellar climbing fibers in the induction of learning and in the timing of movement, but the evidence provided for the many sweeping claims is incomplete. The paper would benefit from additional statistical analyses to more rigorously evaluate the central claims, with consideration of appropriate comparison groups and potential confounds.

    1. eLife assessment

      This important study uses mathematical modelling to demonstrate that conformational autoinhibition of the RAF kinase is an important feature of its paradoxical activation by pharmacological inhibitors. This part of the theoretical analysis is highly compelling but its extension to the investigation of how the binding of 14-3-3 adaptors additionally contributes to the paradoxical activation phenomenon is incomplete and would benefit from more rigorous experimental validation. With the experimental part addressing 14-3-3-dependent regulation strengthened or the 14-3-3 part completely removed, this paper would be of considerable interest to cell biologists and cancer biologists, ultimately paving the way for improved RAF therapeutics.

      In this important study, the authors present evidence for the novel involvement of a scavenger receptor in tubular morphogenesis. Using a convincing set of data, the authors propose that the Drosophila scavenger receptor Emp (homologous to human CD36 ) couples endocytosis of luminal molecules and regulates tube length via controlling Crumbs and Src. This work will be of broad interest to cell and development biologists as well as cancer biologists.

      This valuable Tools and Resources paper presents new tools for investigating GLP-1 signaling: a genetically-encoded sensor constructed from a mutated GLP1R receptor as well as a caged agonist peptide. The evidence for these tools working as advertised is largely convincing and they may be helpful for screening compounds that bind to GLP1R. On the other hand, their overall utility is limited by their very weak apparent affinity relative to the likely biological concentration and response. Incomplete characterization of the properties of the tools makes it difficult to anticipate which applications are most likely to succeed.

      This study examines the role of the locus coeruleus in the extinction of instrumental behaviors. The work is valuable to highlight the function of this part of the brain. Evidence is incomplete as spontaneous recovery is not demonstrated in control subjects. Further analyses on the effect of the manipulations on baseline lever pressing, magazine entries, and the coupling of lever-presses and magazine entries help capture the function of the locus coeruleus.

    1. eLife assessment

      This study aggregates across five fMRI datasets and reports that a network of brain areas previously associated with response inhibition processes, including several in the basal ganglia, are more active on failed stop than successful stop trials. This study is valuable as a well-powered investigation of fMRI measures of stopping. However, evidence for the authors' conclusions regarding the role of subcortical nodes in stopping is incomplete, due to the limitations of fMRI and a lack of theoretical synthesis.

    1. eLife assessment

      Based on a technological advance which couples onboard calcium imaging with in vivo electrophysiology in freely behaving mice, this work presents important insights about the brain circuits through which the cerebellum could participate to social interactions. In particular, correlative measurements provide interesting but incomplete evidence that connections between cerebellum and cingulate cortex connections specifically contribute to the complex sensory-motor computations underlying social contacts. This study is of interest for a broad range of neurophysiologists.

    1. eLife assessment

      This important study reveals the use of an allocentric spatial reference frame in how the perception of the location of a dimly lit target is updated during locomotion.

This work will be of broad interest to neuroscientists.

    1. eLife assessment

      The study provides valuable insights into allosteric regulation of BTK, a non-receptor protein kinase, challenging previous models. Using a variety of biophysical and functional techniques, the paper presents evidence that the N-terminal PH-TH domain of BTK exists in a conformational ensemble surrounding a compact SH3-SH2-kinase core, that the BTK kinase domain can form partially active dimers, and that the PH domain can form a novel inhibitory interface after SH2/SH3 disengagement. Overall the presented evidence is solid, but the EM results may be over-interpreted and the work would benefit from additional functional validation.

      The manuscript describes a valuable theoretical calculation focusing on the structural changes in the photosynthetic reaction center postulated by others based on time-resolved crystallography using X-ray free-electron laser (XFEL) (Dods et al., Nature, 2021). The authors argue that calculated changes in redox potential Em and deformations using the XEFL structures may reflect experimental errors rather than real structural changes. The study is still incomplete in the sense that it focuses on explaining why the proposed structural changes do not match the theoretical calculations, but it does not yet provide an alternative model.

      This study and associated data is compelling, novel, important, and well-carried out. The study demonstrates a novel finding that different chemotherapeutic agents can induce nucleolar stress, which manifests with varying cellular and molecular characteristics. The study also proposes a mechanism for how a novel type of nucleolar stress driven by CDK inhibitors may be regulated. The study sheds light on the importance of nucleolar stress in defining the on-target and off-target effects of chemotherapy in normal and cancer cells.

      This study by Verdikt et al. provided solid evidence demonstrating the potential impacts of Δ9-tetrahydrocannabinol (Δ9-THC) on early embryonic development using mouse embryonic stem cells (mESCs) and in vitro differentiation. Their results revealed that Δ9-THC enhanced mESCs proliferation and metabolic adaptation, possibly persisting through differentiation to Primordial Germ Cell-Like Cells (PGCLCs), though the evidence supporting this persistence was incomplete. Although the study is important, it was limited by being conducted solely in vitro and lacking parallel human model experiments.

      The study by Gu et al. presents direct evidence on the role of microglia morphological dynamics during sleep/wake cycles and the modulatory effect of sleep deprivation, making it a valuable contribution to the ongoing investigation of microglial function. The use of a novel miniature two-photon microscope technique adds strength to the evidence supporting the conclusions. However, concerns remain about certain methodological and experimental aspects of the study, indicating that further validation is necessary and that the evidence presented is currently incomplete.

    1. eLife assessment

      The discovery of Homo naledi-associated evidence for intentional burial and engravings would undoubtedly have important implications for our understanding of the evolution of complex cognition and behavior. Based on claims made in two related preprints by Berger et al., this study discusses the potential implications of the purported mortuary practice and symbolic behaviors claimed to be associated with the small-brained H. naledi remains. Unfortunately, the evidence presented in the two related submissions that the current paper entirely relies on is incomplete at this stage.

    1. eLife assessment

      This paper presents important information about potentially Homo naledi-associated markings discovered on the walls of the Hill Antechamber of the Rising Star Cave system, South Africa. If confirmed, the antiquity, intentionality, and authorship of the reported markings will have profound archaeological implications, as such behaviors are otherwise widely considered to be unique to our species, Homo sapiens. As it stands, the study is incomplete, and the evidence presented does not support the claims about the anthropogenic nature, age, and author of the engravings. While it is appreciated that this report concerns preliminary findings, all reviewers agree that: a) the initial nature of the reported results must be more clearly indicated, b) the anthropogenic nature of the engravings must be adequately demonstrated, c) ideally the chronology of the claimed engravings has to be established for any age estimate to be reliable, and d) the claim about H. naledi being the author of the reported engravings requires robust association.

    1. eLife assessment

      The authors study the context of the skeletal remains of three individuals and associated sediment samples to conclude that the hominin species Homo naledi intentionally buried their dead. Demonstration of the earliest known instance of intentional funerary practice – with a relatively small-brained hominin engaging in a highly complex behavior that has otherwise been observed from Homo sapiens and Homo neanderthalensis – would be a landmark finding. However, the evidence for these claims is considered inadequate in the current version of the study. The four reviewers were in strong consensus that the methods, data, and analyses do not support the primary conclusions. Without full excavations, the study is missing crucial geoarchaeology (especially micromorphology) and taphonomic components, among other limitations, that make premature the conclusion that H. naledi intentionally buried their dead. The null hypothesis must be that these skeletons accumulated naturally and the research must then reject the null hypothesis and robustly exclude equifinality in order to justifiably draw the remarkable conclusions made in the present version of the paper.

    1. eLife assessment

      This important study illustrates the value of museum samples for understanding past genetic variability in the genomes of populations and species, including those that no longer exist. The authors present genomic sequencing data for the extinct Xerces Blue butterfly and report convincing evidence of declining population sizes and increases in inbreeding beginning 75,000 years ago, which strongly contrasts to the patterns observed in similar data from its closest relative, the extant Silvery Blue butterfly. Such long-term population health indicators may be useful for highlighting still extant but especially vulnerable-to-extinction insect species -- irrespective of their current census population size abundance.

      This important article provides insights into the neural centres in the Japanese quail brain that are associated with photoperiod-induced life-history states. The physiological and transcriptomic analyses of the mediobasal hypothalamus and pituitary gland offer evidence for a coincidence timing mechanism for measuring day length, which is relevant for the field of circannual biology. Despite some shortcomings in data analysis, the study's convincing experiments and findings have the potential to captivate the attention of molecular and organismal endocrinologists.

    1. eLife assessment:

      This important study describes spatial RNA processing events by combining methods for single-cell transcriptomics data with spatial transcriptomics data. The evidence supporting the claims of the authors is solid, although the analysis could be further strengthened by including a broader range of samples as well as orthogonal validation either by experimental methods or simulated data. The work will be of general interest to researchers in the spatial transcriptomics field as well as researchers investigating alternative pre-mRNA processing across diverse tissues.

    1. eLife assessment:

      Trypanosoma brucei evades mammalian humoral immunity through the expression of different variant surface glycoprotein genes. In this fundamental paper, the authors extend previous observations that TbRAP1 both interacts with PIP5Pase and binds PI(3,4,5)P3, indicating a role for PI(3,4,5)P3 binding and suggesting that antigen switching is signal dependent. While much of the evidence is compelling, one reviewer suggested that the work would benefit from further controls.

    1. eLife assessment

      This paper describes an important, well-organized study into an under-exploited area of spatial transcriptomics. The limitations of the approach are generally made clear, but there is insufficient orthogonal validation to demonstrate the biological significance of the results, which leads to the evidence for the claims being currently incomplete. Nevertheless, the tools presented will provide a resource to researchers wishing to characterise spatial patterning of mRNAs, and the paper will be of interest to researchers studying cell biology, RNA biology, and method development for spatial transcriptomics/proteomics.

    1. eLife assessment

      This important paper reports a novel, compelling method, based on barcoding viral genes and next-generation sequencing, to quantify both viral transcription levels and progeny virus production in influenza virus-infected cells at the single-cell level. The authors show that viral transcription and progeny virus production are unexpectedly poorly correlated, and that cells in which viral RNAs are transcribed at high levels are not necessarily those producing the most progeny virions. Because of its novelty, the study will be of interest to the broader virology community.

    1. eLife assessment

      This is an important study that reports the discovery of a new pathway of miRNA sorting to exosomes, involving a mitochondrially-localized protein. The evidence provided by some of the biochemical data is convincing. However, the major body of evidence is still incomplete.

      This US study presents findings from an online survey and in-person interviews of healthcare providers in areas associated with cervical screening provision during the post-acute phase of the pandemic. The findings are valuable as they provide insights into a range of areas, from healthcare characteristics to screening barriers and HPV self-sampling. The evidence supporting the claims of the authors is solid, although the inclusion of a nationally-representative sample of healthcare providers and a greater gender/ethnicity/racial mix of interviewees would have strengthened the study. The work will be of interest to public health scientists and a cancer prevention and control audience.

    1. eLife assessment

      This manuscript suggests a novel mechanism of purifying selection by which programmed cell death contributes to the selective removal of mtDNA deletion mutations in C. elegans. The evidence for this mechanism of removal is strong although questions remain regarding the underlying mechanism and the role of canonical ageing pathways. Because of the likely central role of mtDNA deletions in ageing and age-dependent diseases, this work will be of interest to scientists in the field of mitochondrial biology as well as ageing.

      This important paper describes a valuable systematic review and meta-analysis of mental health problems in polycystic ovary syndrome (PCOS) that drive the excess economic burden associated with this common endocrine disorder. Interestingly, the cost of the diagnostic evaluation is only a relatively minor part of the total costs, but mental health disorders were identified as a significant component of the economic burden. These solid findings could not have been anticipated intuitively and are of considerable value for public health prioritization of PCOS.

      This important study used high-resolution brain imaging methods to visualize and index non-invasively auditory and language pathways of young children born with inner ear malformations or cochlear nerve dysfunction resulting in profound hearing loss. Nerve fiber impairments were compellingly demonstrated in subcortical auditory and cortical language pathways relative to typically-hearing controls. The results suggested novel approaches for clinical assessment of central auditory and language pathways that may influence different intervention strategies, pending further evidence linking these structural findings with functional outcomes.

      Rodberg et al. show systemic β adrenergic antagonism reduces engagement in decision-making, particularly in female rats, and reduces task-related encoding in neural activity. This is a valuable finding that addresses a gap in the field, however, the understanding of the direct contribution of β adrenergic receptors to the observed effects is incomplete. Further, the theoretical grounds, data analyses, and results could be improved in several ways.

    1. eLife assessment

      The manuscript represents a valuable contribution to an ongoing discussion about the substrate binding site and mechanism of the Bile Acid Sodium Symporter (BASS) family of transporters. Structural and biochemical analysis of a bacterial homolog, ASTBnm, in complex with its native substrate (not bile acids, but a vitamin A precursor, pantoate) show a new binding site that is consistent with classical proposals for elevator-type transport mechanisms. Molecular simulations highlight the improved stability for the substrate in the active site when ions are present, suggesting a binding order during the transport cycle. The structural studies, binding assays, and MD simulations are convincing, although support for the transport mechanism is incomplete without a pantoate transport assay.

The results should be of interest to parasitologists and eukaryotic cell biologists.

    1. eLife assessment

      This study includes important findings on protein evolution, namely that changes in function are largely attributable to pairwise rather than higher-order interactions, and that epistasis potentiates rather than constrains evolutionary paths. Compelling evidence supporting the conclusions is provided by applying a new model to a previously generated experimental dataset on deep mutational scanning of the DNA-binding domain (DBD) of steroid hormone receptor. The implications of this work are of considerable interest to protein biochemistry, evolutionary biology, and numerous other fields.

      The paper provides a useful and novel application of recursion theory to the long call vocalisations of orangutans to demonstrate repetitive, rhythmic sub-structuring. However the evidence provided to support the major claims of the paper is currently incomplete. Specifically, it is not yet clear how the rhythmic structuring found in these long calls is more similar to human language recursion per se rather than isochrony as a broader, more common phenomenon.

      This important study describes a combination of in vitro and in vivo results implicating Dyrk1a in the regulation of mTOR. Strengths include the combination of cell and whole-animal (Drosophila) based studies. However, the evidence supporting the conclusions is incomplete and additional experimentation (which could include IPs, more confirmation of the T1462 phosphorylation, and more information about Akt) would strengthen the main conclusions.

    1. eLife assessment

      This study reports important findings about new locomotory dynamics of crawling Drosophila larva based on imaging the reaction forces during larval crawling. The new high-resolution microscopy method is compelling, as it significantly improves the spatial, temporal, and force resolution compared to previous methods for studying Drosophila larva and could be applied to other crawling organisms. The manuscript would nevertheless benefit from more details explaining the new technology, limitations, and justifications for the choice of technology and certain experimental details. The work will be of interest to the broad neuroscience community interested in the mechanisms of locomotion in a highly tractable model.

    1. eLife assessment

      This study reports the important finding that there appears to be a timer that monitors the repair of DNA after damage and regulates whether cells are subsequently able to enter mitosis. The authors identify proteins important for this decision and propose a mechanism supported by solid but not conclusive data. This study will be of interest to researchers in the fields of DNA damage repair and cell cycle control.

    1. eLife assessment

      In this important study, the human membrane receptor guanyl cyclase GC-C was expressed in hamster cells, co-purified in complex with endogenous HSP90 and CDC37 proteins, and the structure of the complex was determined by cryo-EM. The study shows that the pseudo-kinase domain of GC-C associates with CDC37 and HSP90, similarly to how the bona fide protein kinases CDK4, CRAF and BRAF have been shown to interact. The methodology used is state of the art and the evidence presented is compelling.

    1. eLife assessment

      This study is useful to scientists studying cell polarity, epithelial morphogenesis, cancer, and primary cilia. The authors confirm the need for CRB3A/B in regulating ciliogenesis by using a combination of a mammary epithelial cell-specific conditional Crb3 knockout mouse model, and cellular, molecular and biochemical approaches. The results are solid, supporting and extending previous findings; the results also indicate that CRB3 affects ciliogenesis by a still incompletely understood mechanism involving Rab11 and gamma-TuRC.

      This important paper reports technical advances for in vivo intramuscular electrical recording from multiple motor units in behaving animals. This new muscle recording method has the potential to provide new insight into a range of questions in motor neuroscience. The paper includes compelling demonstrations of the efficacy of this new technique in multiple animal species, although further evidence is needed to support the claim that electromyogram "spike sorting" can reliably disambiguate individual motor units.

    1. eLife assessment

      This study documents valuable findings on three variants in SNAP25 that are associated with developmental and epileptic encephalopathy. The thorough characterization of synaptic release and in vitro vesicle fusion phenotypes provides interesting information about the nature of the SNAP25 variants. The evidence supporting the claims is compelling, and this work will be of interest to neuroscientists working on SNAP25, SNAP25-associated encephalopathy, and synaptic vesicle exocytosis.

    1. eLife assessment

      This study examines how self-citations in the neuroscience literature differ according to geography, gender, seniority, and subfield within neuroscience. The evidence supporting the claims is mostly solid, but aspects of the analysis - notably concerning estimates of uncertainty, and the exact interpretation of the results - would benefit from further work. Overall, the article is a valuable addition to the literature on self-citations

    1. Editor’s Assessment

      This work has generated metabolic models for the human pathogens Mycobacterium leprae and Mycobacteroides abscessus, alongside a new computational tool that can be used to identify potential drug targets. The standardised genomic scale metabolic models have been developed using the systems biology community standards for quality control and evaluation of models.

    1. eLife assessment

      This manuscript addresses an important question, that in countries endemic for P. vivax the need to administer a primaquine (PQ) course adequate to prevent relapse in G6PD deficient persons poses a real dilemma. On one hand PQ will cause haemolysis; on the other hand, without PQ the chance of relapse is very high. As a result, out of fear of severe haemolysis, PQ has been under-used. This manuscript is convincing that regimen (1) can be used successfully to deliver within 3 weeks, under hospital conditions, the dose of PQ required to prevent P. vivax relapse.

    1. eLife assessment

      This important study tested the hypothesis that liver-derived but not serum-derived antibodies that are cross-reactive to E.coli and to host proteins can play a role in the hepatic damage found in severe alcoholic hepatitis (SAH). Using a solid methodology that includes state-of-the-art microscopy, proteome arrays, and gene ontology assays, it provides strong evidence that liver-derived IgG and IgA with cytotoxic properties and reactivity to both gut-derived E.coli and autoantigens accumulated in hepatocytes of SAH patients but not of healthy controls. The study would benefit from a broader analysis of gut microbiota proteome and further characterization of B cells infiltrating the liver tissue including their numbers/field and their origin (infiltrating versus resident cells). The work opens new avenues of understanding for the pathogenesis of severe alcoholic hepatitis and is of great interest to researchers and clinicians in the field.

    1. eLife assessment

      This paper presents a useful study regarding the meiotic functions of ARID1A, the DNA-binding component of the SWI/SNF chromatin remodeler BAF. Whereas this work suggests that ARID1A regulates chromatin composition of the sex body relative to the autosomes, the reviewers raised substantial issues with the data and interpretation. The efficiency of the conditional deletion allele seems low and the CUT&RUN experiments are inadequate.

      The OpenApePose dataset presented in this manuscript represents an important contribution to the field of primate behaviour and computer-vision science with methodological applications that are sure to be applicable for a wide variety of taxa. The analysis supporting the utility of this database is solid and compelling but would benefit from some additional clarity, particularly with regards to the landmark annotations, model parameters and division of the dataset for training, validation and testing.

    1. eLife assessment

      This study presents a valuable finding on the role of fragile X messenger ribonucleoprotein (FMRP) and its target the microtubule associated protein 18 (MAP1B) in postnatal tangential migration of neuroblasts. The study combined molecular genetics (FMRP knock-out mice) with acute inactivation of FRMP and MAP1B to conclusively support the notion that FMRP-dependent regulation of MAP1B is necessary for proper neuronal migration toward the olfactory bulb using the rostral migratory stream. The evidence supporting the claims of the authors is solid, although inclusion of additional controls for experiments and/or more rigorous description of the finding and conclusions would have strengthened the study. The work improves our knowledge of the molecular mechanisms that control how neurons migrate in the brain to reach their final destinations and confirms that cytoskeleton regulators are key players in this process. will be of interest to developmental neurobiologists.

      This important study unravels the interaction between effort cost, pupil-indexed brain state, and movement (saccadic) vigor during foraging decisions in marmoset monkeys. Based on a computational model, the authors derive the prediction that anticipated effort should affect both decisions and movement vigor during foraging; and then provide solid behavioural and pupillometric evidence for this prediction in a foraging task. This paper will be of interest to decision and motor neuroscience as well as to all researchers studying animal behavior.

    1. eLife assessment

      This is an important paper that links distinctive stinging behavior of two related anemones occupying different ecological niches to varying inactivation properties of voltage-gated calcium channels conferred by auxiliary Cavβ subunits. Further convincing evidence is provided that these differences are mediated by alternative splicing of Cavβ subunit of the calcium channel. The study will be of interest to scientists studying Ca2+ signaling, ion channel biophysicists, and marine biologists.

      Gap junctions, formed from connexins, are important in cell communication, allowing ions and small molecules to move directly between cells. By determining the Cryo EM structure of the structure of connexin 43 in a putative closed state involving lipids, the study makes an important contribution to the development of a mechanistic model for connexin activation. The connexin 43 structure is solid and its presentation will appeal to the channel and membrane protein communities.

    1. eLife assessment

      This important paper uses a genome-wide, massively parallel reporter assay to determine how CpG methylation affects regulatory sequences that control the expression of human genes. The authors provide compelling evidence that methylation not only influences baseline activity of regulatory sequences but also the magnitude of acute responses to environmental stimuli. The findings are of broad interest, and the extensive data set will likely become a key resource for the community.

    1. eLife assessment

      This study describes important findings on how a core component of the circadian clock impacts the effect of dietary restriction (DR) on longevity and fecundity in Drosophila, which lead the authors to postulate rhythmic control of proteostasis in the fat body as a critical aspect of DR effects. The evidence presented is still incomplete, not fully supporting the conclusions of the study, as alternative hypotheses/explanations have not yet been systematically explored. The work will nevertheless be of substantial interest to researchers working in circadian and cell biology, metabolism, and aging, with an interesting hypothesis to be explored further.

      Like other mollusc species, the freshwater pearl mussel (Margaritifera margaritifera) has a challenging genome to assemble owing to the large size of their genomes, heterozygosity, and repetitive sequence. The first published M. margaritifera genome was highly fragmented, but here an improved reference genome assembly was generated using PacBio CLR long reads to reduce fragmentation levels, missing and truncated genes, and chimerically assembled regions. The number of gene models predicted is a bit higher compared than other molluscan genomes, but after clarification and double checking these seem in line with some Mollusca and Bivalvia with similar and higher numbers of gene predictions. This new genome represents a new resource to start exploring the many biological, ecological, and evolutionary features of this threatened and commercially important group of organisms.

      Hybrid genomes are tricky to assemble, and few genomic resources are available for hybrid grapevines such as ‘Chambourcin’, a French-American interspecific hybrid grape grown in the eastern and midwestern United States. Here is an attempt to assemble Chambourcin’ using a combination of PacBio HiFi long-reads, Bionano optical maps, and Illumina short-read sequencing technologies. Producing an assembly with 26 scaffolds, an N50 length 23.3 Mb and an estimated BUSCO completeness of 97.9% that can be used for genome comparisons, functional genomic analyses, and genome-assisted breeding research. Error correction and pilon polishing was a challenge with this hybrid assembly, but after trying a few different approaches in the review process have improved it, and as they have documented what they did and are clear about the final metrics, users can assess the quality themselves.

      In this valuable study, advanced simulation methodologies are used to extract the mechanisms of inactivation for the potassium ion channel KcsA. The string method approach provides solid evidence that reveal features associated with the interplay between gate size and collapse of the selectivity filter, as well as remarkable differences between different force fields. While this manuscript does not address recent discoveries in K channel inactivation involving dilated selectivity filter structures obtained by Xray and cryo-EM, it does help us understand the KcsA constriction process. With added descriptions and analysis of collective variables, improved reproducibility of results, consistency between string method free energies and unbiased simulations, and improved transition rate calculation, this manuscript will be of interest to the ion channel field.

    1. eLife assessment

      This important study uses machine learning-based network analysis on transcriptomic data from different tissue cell types to identify a small set of conserved (pan-tissue) genes associated with changes in cell mechanics. The new method is compelling and, together with rigorous in silico and experimental validation, provides convincing evidence for the claims. The study would be strengthened with an expanded set of validation (e.g. testing genes with hitherto unknown roles and different perturbation techniques), but will nonetheless be of broad interest to cell biologists, biophysicists, and bioengineers.

    1. eLife assessment

      This important study combines virology experiments and mathematical modeling to determine the nuclear export rate of each of the eight RNA segments of the influenza A virus, leading to the proposal that a specific retention of mRNA within the nucleus delays the expression of antigenic viral proteins. The proposed model for explaining the differential rate of export is compelling, going beyond the state of the art, but the experimental setup is incomplete and would benefit from additional approaches. The insight so far is interesting, but because in the end it is left as an observation, the overall advance remains limited.

    1. eLife assessment

      This study presents the valuable finding that sustained calcium signaling in induced-Treg (iTreg) cells can lead to the loss of Foxp3 expression and iTreg identity by altering the chromatin landscape. The evidence supporting the claims of the authors is solid, but alternative interpretations of the data should be considered and tested. The work will be of interest to immunologists working on Treg cell therapy.

    1. eLife assessment

      This study provides useful findings regarding the capacity for mental state attribution on the Frith-Happé task in a highly social non-human primate species, the marmoset. The methods are solid, integrating validated brain imaging and eye-tracking techniques, however, the theoretical analysis is incomplete due to the omission of a "goal-directed condition." The inclusion of the goal-directed condition would enable a stronger interpretation of the findings and would be of broad interest to neuroscientists working in social and affective sciences.

      This study provides important new insights into how learning affects behavior in the Drosophila model. Using a combination of connectomics, neurophysiology, and behavioral analysis, a small group of neurons in the Drosophila brain that integrates learned odor valences and promotes odor tracking by driving upwind orientation and movement is described. The study's conclusion is supported by convincing evidence and rigorous quantitative analysis. Insights from the neural circuit mechanism that translates learning-induced plasticity into appropriate behavioral actions will be of broad interest to neuroscientists.

    1. eLife assessment

      This simulation work with open source code will be of interest to those developing visual prostheses and demonstrates useful improvements over past visual prosthesis simulations. While the authors provide compelling evidence to support the generation of individual phosphenes and integration into deep-learning algorithms, the assumptions beyond individual phosphenes and the overall validation process are inadequate to support the claim of fitting the needs of cortical neuroprosthetic vision development.

    1. eLife assessment

      This study provides useful information on the impact of the pandemic on the quantity of healthcare delivered to patients with pancreatic cancer in England. The authors showed that there was no difference in the number of diagnoses of pancreatic cancer during the pandemic compared to the preceding 5-year period, but a reduction in surgical resections by nearly 25%. They reported no difference in deaths between the two periods. They show no differences in rates of diagnosis, but the clinical relevance is incomplete as they have not compared survival from cancer between those time periods.

      This fundamental study provides compelling evidence that long-range resection is important for recombination between distal, but not proximal, homologous sequences. It is thus proposed that a major role of long resection of a double-strand break mediated by Sgs1 and Exo1 is to activate the DNA damage checkpoint to allow the chromosomal mobility needed for the DNA ends to find a distant homologous sequence with which repair via homologous recombination, adding a new biological meaning to the role of long DNA resection in homologous recombination.

      The mechanisms underlying mirror neurons are a topic of wide interest for all who study the workings of the brain. The authors use an elegant decoding approach to test whether mirror neurons encode action categories in the same framework regardless of whether actions are executed in the dark or observed in the light. This new approach identifies only a small subset of mirror neurons with fully matched coding among a larger set showing partial matches. The thought-provoking study opens up new principled avenues to probe the mechanics of matching action and perception.

Deeper interpretation of novel mechanistic insights that are gained would benefit the study.

    1. 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 therapy were not statistically different from those in the control group.

    1. eLife assessment

      This fundamental study substantially advances our physical understanding of the sharp increase and saturation of the viscosity of non-confluent tissues with increasing cell density. Through the analysis of a simplified model this study provides compelling evidence that polydispersity in cell size and the softness of cells together can lead to this phenomenon. The work will be of general interest to biologists and biophysicists working on development.

      This study presents valuable findings describing how two brain regions, the midbrain periaqueductal gray matter and basolateral amygdala, communicate when a robotic predator threat is detected. While the experimental design and data collection methods are solid, the main claims are only partially supported by the data and would benefit from more rigorous anatomical approaches as well as functional validation of the role of the paraventricular nucleus of the thalamus as the critical connection between the periaqueductal gray and basolateral amygdala. The study will appeal to a broad audience, including basic scientists interested in neural circuits, basic and clinical researchers interested in fear, and behavioral ecologists interested in foraging.

    1. eLife assessment

      This potentially important study used single-cell whole-brain imaging of the immediate early gene Fos to identify the brain areas recruited by two anesthetics, ketamine and isoflurane. The results suggest these anesthetics might induce anesthesia via different brain regions and pathways. However, the support for the primary conclusions is incomplete owing to differences in route of administration between the drugs, lack of a dose response curve and behavioral/physiological measures of the depth of anesthesia, and statistical analysis that does not correct for multiple comparisons. With these issues addressed, this paper would be of interest to preclinical and clinical scientists working with anesthetic and dissociative drugs.
