      This important study aims to discover the mechanisms governing the switch between conventional DNA replication and the specialized mechanism of telomere end replication. Solid genetic and biochemical assays suggest an interplay between sumoylated PCNA and chromosome terminal capping proteins. The questions addressed have implications for several fields, such as genome stability.

      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. The evidence supporting this claim is convincing, based on a series of cleverly and carefully designed behavioral experiments. The results will be of interest not only to scientists who study perception, action and cognition, but also to engineers who work on developing visually guided robots and self-driving vehicles.

    1. eLife assessment

      This important work advances our understanding of the differences in locomotion-induced modulation in primate and rodent visual cortexes. The evidence in support of these differences across species is convincing, although greater use of the primate dataset with some additional analyses would have strengthened the claims. 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.

    1. eLife assessment

      This is a valuable study of the molecular basis of summer-to-winter transition in Cacopsylla chinensis. Despite the convincing molecular and organism-level experiments, evidence of cold sensitivity in the protein of interest is incomplete, with a lack of methodological detail. The results of this study will be of interest to entomologists.

    1. eLife assessment

      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.

    1. eLife assessment

      This interesting study describes the development of a three-dimensional cell culture system to investigate muscle tissue development and homeostasis. It is a solid study that could be valuable in the study of human as opposed to animal cells in studying muscular disorders.

    1. eLife assessment

      This study presents useful findings regarding the impact of forest cover and fragmentation on the prevalence of malaria in non-human primates. The evidence supporting the claims of the authors is, however, incomplete, as the sampling design cannot adequately address the geospatial issues that this study focuses on.

    1. eLife assessment

      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.

    1. eLife assessment

      This manuscript describes useful information on in vitro binding and hydrogen exchange (HDX) mass spectrometry experiments using various bacterial-expressed BRAF N-terminal fragments, to tease out domain-specific interactions with RAS proteins or wildtype and oncogenic mutant BRAF kinase fragments. The characterization of the auto-inhibitory mechanism of the regulation of BRAF is solid but several concerns remain. The data will be of interest for researchers in the RAS/RAF and general kinase regulation fields.

    1. eLife assessment

      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.

    1. eLife assessment

      Brain inflammation is a hallmark of multiple sclerosis. Using novel spatial transcriptomics methods, the authors provide convincing evidence for a gradient of immune genes and inflammatory markers from the meninges toward the adjacent brain parenchyma in a mouse model. This important study advances our understanding of the mechanisms of brain damage in this autoimmune disease.

    1. eLife assessment

      This research advance article describes a valuable image analysis method to identify individual cells (neurons) within a ‎population of fluorescently labeled cells in the nematode C. elegans. The findings are solid and the method succeeds to identify cells with high precision. The method will be valuable to the C. elegans research community.

    1. eLife assessment

      This important study characterises the involvement of condensin complexes in the segregation of telomeres in fission yeast. The authors present solid evidence in support of their claims, employing a diverse range of complementary techniques. This research will be of interest for cell biologists working on chromosome biology and cell division.

    1. eLife assessment

      This valuable study describes engineered dengue virus variants that can be used to dissect epitope specificities in polyclonal sera, and to design candidate vaccine antigens that dampen antibody responses against undesirable epitopes. The evidence supporting the major claims is solid, although experiments to distinguish the impact on antibody binding versus neutralizing activities would have strengthened the study. This work will be of interest to virologists and structural biologists working on antibody responses to flaviviruses.

    1. eLife assessment

      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.

    1. eLife assessment

      Overall, this is an interesting topic of study, and the conclusions could be of relevance more broadly. However, mechanistic support, limited TTF frequencies/timing, and visual support of the quantitative data would be critical in order to provide convincing and rigorous support for this interesting concept.

    1. eLife assessment

      This study explores the regulatory function of O-GlcNAcylation on DNA methyltransferase 1 and identifies serine 878 as the main target. This study is of interest to those in epigenetics and metabolism. The significance is important and the strength of the evidence is convincing.

    1. eLife assessment

      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.

    1. eLife assessment

      This work provides a valuable structural and functional characterization of the neurotransmitter's spatial distribution heterogeneity in cortical and subcortical regions. The authors report a systematic description and annotation of a new "layer" of brain organization that has been relatively poorly integrated with the wider neuroimaging literature to date. In sum, this paper has the potential to be of great interest to a wide audience in neurosciences.

    1. eLife assessment

      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.

    1. eLife assessment

      This study presents a valuable and elegant kinetic analysis of the GSKbeta activity as a function of phosphorylation and Axin binding - providing insights into critical steps of Wnt pathway signaling. The results will be of big use to the broader signaling community, however, the incomplete dissection of the mechanism by which Axin binding inhibits GSKbeta inhibitory phosphorylation remains a weakness of this study. The work will be of broad interest to cell biologists and biochemists.

    1. eLife assessment

      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.

    1. eLife assessment

      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

      This work provides fundamental new insight into fine axonal morphologies based solely on extracellular action potential recordings. They provide compelling evidence of fine resolution in mapping functional connections between neurons. The work may have broad use in neurobiology, bioengineering, stem cell biology, as well as tissue engineering in functional characterization.

    1. eLife assessment

      The tool developed and implemented in this study has valuable significance for the combined analysis of large, diverse omics datasets, but some of the methodology is incomplete. Regarding the strength of evidence, there are some more significant concerns regarding potentially inadequate controls for false discovery and multiple testing corrections.

    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.

    1. eLife assessment

      This important study advances our knowledge of how parasites evade the host complement immune system. The new cryo-EM structure of the the trypanosome receptor ISG65 bound to complement component C3b is highly compelling and well-supported by biochemical experiments. This work will be of broad interest to parasitologists, immunologist, and structural biologists.

    1. eLife assessment

      This important study identifies two new transporters of the apicoplast, a non-photosynthetic organelle of apicomplexan parasites. In its current state, evidence is incomplete, as it only partially reveals how important those transporters are and as it does not address the metabolic function for the parasite. 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.

    1. eLife assessment

      This fundamental study identifies the components of the N6-methyladenosine methyltransferase complexes in yeasts, with major differences with the same complexes in mammals and flies. The evidence supporting the conclusions is convincing, with rigorous high-throughput sequencing approaches and detailed functional analysis. This work will be of broad interest to colleagues in the RNA modification and meiosis fields.

    1. eLife assessment

      This valuable study examined the use of dantrolene, a Ryanodine Receptor stabilizer, in slowing pathological progression of pressure-overload heart failure in a guinea pig model and reducing arrhythmias. The data were collected and analyzed using solid and validated methodology and can be used as a starting point for future studies of dantrolene in Ca2+ handling in ROS production and further deterioration of cardiac function in chronic heart failure.

    1. eLife assessment

      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.

    1. eLife assessment

      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.

    1. eLife assessment

      This study represents an important contribution to the field by supporting the utility of functional ultrasound imaging for evaluating cerebral hemodynamics in rat models of brain injury. Solid evidence is presented supporting the possibility of imaging the effect of thrombolysis during stroke in awake rats. This work will be of interest to researchers working in functional neuroimaging and more precisely with preclinical models of stroke in rodents.

    1. eLife assessment

      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 important work examines the potential utility of socio-emotional and socio-cognitive mental training on hippocampal subfield structure and function, and cortisol levels. The evidence provided here is solid, but additional methodological considerations are needed to strengthen the evidence in support of their claims. The work will be of broad interest to neuroscience researchers including those in cognitive, social, and clinical neuroscience.

    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. After providing more detail on reproducibility, comparative performance of the models, and reuse, these resources are now published and are available for reuse by the global scientific community via the GigaDB, Biomodels, and PatMeDB repositories.

      This assessment refers to version 1 of this preprint.

    1. eLife assessment

      This study demonstrates that vitamin D-bound VDR increased the expression of SIRT1 and that vitamin D-bound VDR interacts with SIRT1 to cause auto-deacetylation on Lys610 and activation of SIRT1 catalytic activity. This is an important finding that is relevant to the actions of VDR on colorectal cancer. The data presented to support the presented conclusion are convincing.

    1. eLife assessment

      This valuable study provides solid evidence that acute experimental pain induces changes in cortical excitability and GABAergic neurotransmission. The findings will be of interest to researchers interested in the brain mechanisms of pain and may lay the ground for future studies on acute pain-related excitability changes as probed by TMS and EEG.

    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.

    1. eLife assessment

      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.

    1. eLife assessment

      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.

    1. eLife assessment

      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.

      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.

      This valuable study provides insights into mechanisms of placental aging and its relationship to labor initiation. The authors provide solid evidence and have thoroughly investigated the molecular characteristics of normal placental aging using in vivo and in vitro model systems and human placental tissue analysis to corroborate their findings. This work contributes to existing work in placental aging and preterm birth and will be of interest to reproductive scientists.

    1. Editor’s Assessment

      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.

      This assessment refers to version 2 of this preprint.

      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.

      The primary goal of this paper is to examine microtubule detyrosination as a potential therapeutic target for axon regeneration. The valuable findings of this study provide convincing evidence for mechanistic links between microtubule detyrosination and neurite outgrowth in vitro and some evidence for axon regeneration in vivo.

    1. eLife assessment

      This fundamental study provides a framework for leveraging systems genetics data to dissect mechanisms of gut physiology. The authors provide compelling analyses to highlight diverse modes of interrogating intestinal inflammation, dietary response, and consequent impacts on inflammatory bowel disease. As a resource, it will have great utility for linking genetic variation and diet to gut-related pathophysiologies.

    1. eLife assessment

      This study presents an important description on the dynamics of histone variant exchange controlling the organization of the chromatin state of the Arabidopsis genome, combining the analysis of histone variants, histone modification, and chromatin states. The evidence supporting the claims of the authors is compelling. This work will be of great interest to those in the field of epigenetics and chromatin biology.

    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.

      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.

    1. eLife assessment

      This is an important study reanalysing previously published datasets to understand methylation changes during aging. The evidence supporting the conclusions is solid and sheds new light on features of aging in cells, highlighting the concept of cell-specific methylation changes and their relationship to other physiological changes such as inflammation that may impact methylation patterns. This work will be of broad interest to cell and molecular biologists.

      This work examines a role for altered splicing in pancreatic tumorigenesis by interrogating effects of a specific mutation in the Sf3b splicing factor in pancreatic organoid and cell line growth primarily, with some in vivo work also performed. There is significant potential in the study but there is a concern about the lack of in vivo validation of claims that are most relevant to metastatic progression and the focus on one specific mechanism at the expense of other possible effects on splicing of factors important for disease progression.

    1. eLife assessment:

      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.

      Using C. elegans as a model organism, the study hones in on the role of ether lipid biosynthesis as an effector of metformin--a process previously implicated in extending lifespan in response to diet--, TOR signalling, and mitochondrial interventions. The data in this paper are compelling, and a better understanding of biguanide impact on metabolism is highly important in the field.

    1. eLife assessment

      This study presents valuable insights into the circuits that are common for innate and learned threat. The evidence supporting the author's conclusions is solid, but the specificity of the circuit targeting methods requires further histological assessment and clarification. 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.

    1. eLife assessment

      This study presents a valuable finding on the impact of metformin-induced shifts in gut microbial community structure and metabolite levels for drug efficacy in a mouse model of liver injury. The current evidence supporting the claims of the authors is incomplete, although inclusion of additional controls and a revision to clarify the reviewer's methodological concerns could strengthen the study. This paper could be of broad interest to researchers across multiple disciplines, including the study of the microbiome, liver disease, and pharmacology.

    1. eLife assessment

      This manuscript provides important evidence on the association between sleep regularity and mortality in the UK Biobank, which is a popular topic in recent sleep and circadian research in population-based studies. The study is based on a large accelerometer study with validated follow-up of incident diseases and deaths, and the data quality and large sample size strengthen the credibility of the conclusion. Overall, the analyses are appropriately done, the manuscript is clearly written, and the strength of the evidence is convincing.

    1. eLife assessment

      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.

    1. eLife assessment

      This study provides an important investigation of the role that alpha-band activity modulations play in the generation of the P300. The data offer solid evidence in favour of such a role although further analyses may be required to determine whether the observed relationships may be driven by inter-individual differences in factors that may modulate both signals in tandem such as skull thickness.

    1. eLife assessment

      This important study dissects the interplay between internal energy homeostasis, food intake and food-related memories, focusing on the role played in Drosophila by Octopamine, a monoamine functionally related to noradrenalin. This work will help interpret previously published work on the function of Octopamine, and should be of interest to the growing community of biologists interested in how internal state shapes behavior, including decision making processes, learning and memory. The experimental evidence is solid, but additional evidence using, for instance, tissue-specific and effector-specific manipulation, and a unifying model would strengthen the present study.

      This valuable study reports on the structure and function of capsid size-determining external scaffolding protein encoded by a Vibrio phage satellite. The structural work is of high quality and the presented reconstructions are compelling, but some of the experiments could benefit from a more rigorous statistical analysis of capsid sizes and shapes. The paper offers an important advance in the field of phage and virus structure and assembly with implications for understanding the evolution of phage satellites.

    1. eLife assessment

      This work presents valuable findings on the non-breeding itinerant behavior of a migratory raptor. With its extensive dataset and solid analytical framework, this work will be of broad interest to researchers investigating the ecological drivers of bird migration. However, the main claim on a novel migration pattern (so-called 'fox-trot migration') is incomplete in light of current knowledge on bird migratory behavior.

    1. eLife assessment

      Wang et al present a useful manuscript that builds modestly on the group's previous publication on KLF1 (EKLF) K47R mice focused on understanding how Eklf mutation confers anticancer and longevity advantages in vivo (Shyu et al., Adv Sci (Weinh). 2022). The data demonstrates that Eklf (K74R) imparts these advantages in a background, age, and gender independent manner, not the consequence of the specific amino acid substitution, and transferable by BMT. However, the authors overstate the meaning of these results and the strength of evidence is incomplete, since only a melanoma model of cancer is used, it is unclear why only homozygous mutation is needed when only a small fraction of cells during BMT confer benefit, they do not show EKLF expression in any cells analyzed, and the PD-1 and PDL-1 experiments are not conclusive. The definitive mechanism relative to the prior publication from this group on this topic remains unclear.

    1. eLife assessment

      The authors analyze a comprehensive cohort of human plasma samples to identify an extracellular vesicles protein signature for earlier diagnosis of pancreatic cancer. Application of liquid biopsies is valuable, and it addresses a significant clinical problem as pancreas cancer is often diagnosed in late stage with standard biopsies often nondiagnostic. The strength of evidence is largely solid; however, certain aspects of the data were deemed incomplete, given the broad manuscript claims. This work supports the use of extracellular vesicles in clinical settings, with potential interest to scientists and clinicians.

    1. eLife assessment

      This important study reports that a long non-coding RNA disrupts the activity of the tumor suppressor p53 to contribute to the growth and therapeutic response of glioblastoma. Most evidence supporting the claims of the authors is solid, but the conclusions would benefit from more rigorous approaches. The work will be of interest to biologists working on the non-coding RNA and brain tumors.

    1. eLife assessment

      This represents an important study that demonstrates a high degree of heterogeneity within trailblazer cells in clusters that participate in collective migration. Solid methods highlight this heterogeneity and show that in TNBC cancers, trailblazer cells are defined by vimentin (and not Keratin 14) and are dependent on both TGFbeta and EGFR signaling.

    1. eLife assessment

      This important manuscript presents several structures of the Kv1.2 voltage-gated potassium channel, based on state-of-the-art cryoEM techniques and algorithms. The authors present solid evidence for structures of DTX-bound Kv1.2 and of Kv1.2 in potassium-free solution (with presumably sodium ions bound within the selectivity filter). These structures advance our knowledge of the molecular basis of the channel inactivation process.

    1. eLife assessment

      This valuable study adds to our understanding of the DNA replication origin selection process in budding yeast. The authors provide convincing evidence that the number of possible origins of replication is much higher than previously appreciated, although many of the newly identified origins probably direct replication initiation only very rarely. This work will be of interest to those studying DNA replication and investigating protein-DNA interactions across the genome.

    1. eLife assessment

      This important work substantially advances our understanding of the interplay between genetic variation, chromatin, and genes within topologically associated domains and how this interplay regulates gene expression. The evidence supporting the conclusions is convincing, with appropriate and validated methodology in line with current state-of-the-art genomic and epigenomic techniques. The work will be of broad interest to geneticists and those working to understand the basic mechanisms of gene expression.

    1. eLife assessment

      This study presents valuable findings regarding the role of the transcription factor BATF and its target PD1 in lipid metabolism including a model of nonalcoholic fatty liver disease (NAFLD).

    1. eLife assessment

      The mechanisms that determine when neural stem cells should stop dividing after having generated their full repertoire of progeny remain not completely understood. The authors present useful findings on how Notch activity regulates the termination of neurogenesis in central brain of Drosophila. The evidence supporting the claims of the author is solid, although other complementary approaches could have been used to probe more deeply into the underlying molecular mechanisms. This work will be of interest to developmental neurobiologists.

    1. eLife assessment

      This is a useful investigation of the changes in gene expression and some of the physiological consequences of sublethal exposures to the neonicotinoid insecticide imidacloprid in honeybee larvae. While the study adds to our understanding of how this insecticide impacts development and growth of honeybees, the evidence supporting the major claims is incomplete. The study would benefit from a more thorough mechanistic characterization of the phenotypes to substantiate the conclusions.

    1. eLife assessment

      This valuable study is of relevance for those interested in mechanism required for infections of humans by Klebsiella pneumoniae. The authors apply TraDIS (high-density TnSeq) to K. pneumoniae with the goal of identifying genes required for survival under various infection-relevant conditions. In general, the evidence supporting the identity of the identified genes is convincing, but testing additional individual genes to validate the list inferred from TraDIS data, in addition to complementing the mutants, would be important to provide full support for the claims made. Additional work would also help to unravel novel mechanisms beyond the ones reported.

    1. eLife assessment

      The manuscript by Eyraud and colleagues examines the role of interactions between fibrocytes and CD8 cells as drivers of disease progression in COPD (chronic obstructive pulmonary disease). The findings that there exist bidirectional interactions between CD8 cells and fibrocytes are supported by solid evidence that combines histology of clinical lung samples, in vitro studies obtained from circulating blood fibrocytes and CD8 cells, as well as a computational model that predicts how bidirectional interactions could promote disease progression over the course of 20 years. The study, which is based on patient samples, thus provides fundamental insights on COPD progression.

    1. eLife assessment

      This important study uses the brain endocast of a ~1.9-million-year-old hominin fossil from Kenya, attributed to genus Homo, to show that the organization of the Broca's area in members of early Homo was primitive. Specifically, the prefrontal sulcal pattern in this early Homo specimen more closely resembles that of chimpanzees than of modern humans. Because Broca's area is associated with speech function, the compelling evidence from this study has relevant for understanding the timing and trajectory of evolution of speech related traits in our genus. Coupled with its potential implications for taxonomic classification, this study will be of interest to paleoanthropologists, paleontologists, archaeologists, and neuroscientists.

    1. eLife assessment

      This important study reports that Foxc2+ cells in the testis represent the quiescent spermatogonial stem cells (SSCs). The data supporting this claim are solid. The finding is of great significance to reproductive and stem-cell biology as male fertility depends on the fine balance between self-renewal and differentiation activities of the male germline stem cells, i.e., SSCs.

    1. eLife assessment

      In this valuable study, patients homozygous for both minor frequency alleles of the APOL1 gene are shown to be at significant risk for progression into sepsis after infection. The study has enrolled a significant number of subjects and provides solid results. The study addresses to infectious diseases and critical care experts and one major weakness is the lack of inclusion of non-Black patients.

    1. eLife assessment

      This study presents a valuable finding on the putative molecular patterns underlying characteristic morphological regions observed in colorectal cancer (CRC) and the extent to which morphotype heterogeneity impedes prognostic and predictive expression-based classifiers. The evidence supporting the claims of the authors is solid, although clarity in terms of patient selection and subtype definition would have strengthened the study. The work will be of interest to medical biologists working on colorectal cancer (CRC).

    1. eLife assessment

      This study follows the career trajectories of the winners of an early-career funding award in the United States, and finds that researchers with greater mobility, men, and those hired at well-funded institutions experience greater subsequent funding success. Using data on K99/R00 awards from the National Institutes of Health's grants management database, the authors provide convincing evidence documenting the inequalities that shape faculty funding opportunities and career pathways, and show that these inequalities disproportionately impact women and faculty working at particular institutions, including historically black colleges and universities. Overall, the article is an important addition to the literature examining inequality in biomedical research in the United States.

    1. eLife assessment

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

    1. eLife assessment

      This important study provides a panoramic view of the spectrum of natural variation in C. elegans egglaying behavior, begins to illuminate molecular and genetic influences underlying this variation, and reveals how distinct egglaying behaviors might impact maternal and offspring fitness in diverse environmental conditions. The evidence supporting the authors' conclusions is convincing. This work establishes intraspecific variation in C. elegans egglaying behavior as a model for elucidating the genetic basis for evolutionary transitions between oviparity and viviparity. As such, it will be of interest to evolutionary biologists studying molecular mechanisms underlying fitness tradeoffs between parent and offspring that influence adaptation to changing environments.

    1. eLife assessment

      Scheer and Bargmann provide an important behavioral genetics study on how behavioral context affects decision making of C. elegans. The results and interpretations are overall convincing; the behavioral analysis at multiple time scales combined with genetic and neuronal manipulations revealed how arousal states affect decision making. However, alternative interpretations should be considered and statistical methods should be justified. This work will be of interest to both neuroscientists and ecologists.

    1. eLife assessment

      This important work reports the identification of a list of proteins that may participate in the clearance of paternal mitochondria during fertilization, which is known as essential for normal fertilization and embryonic and fetal development.

      Boyle et al identify Npy-expressing dorsal horn neurons as powerfully inhibiting pain and itch under normal and pathological conditions. The valuable data are convincing, and the effect sizes are robust and directly challenge previous work.

    1. eLife assessment

      This manuscript describes a compelling study demonstrating an important mechanistic role for zinc fluctuations during fertilization. The results show strong evidence that zinc availability modulates inositol triphosphate receptor and that the cytosolic zinc concentration is critical for calcium oscillations that are required for egg activation and fertilization.

    1. eLife assessment

      This work describes the generation of a mouse reporter line dedicated to the visualization and study of the axon initial segment (AIS). This reporter line could be a valuable tool for molecular and cellular studies in neuroscience. In this work, the authors have made an exhaustive characterization of the structural and electrophysiological properties of the labelled neurons and convincingly show that they are unaffected by the expression of the reporter protein.

    1. eLife assessment

      This is an important study examining the behavioural and neural profile of weak and strong fear memories. The data presented provide solid evidence in support of the conclusion that weak but not strong fear memories are more easily modified using behavioural and pharmacological approaches potentially as a result of differential connectivity with the amygdala showing greater connectivity through the brain in weak compared to strong memories. This conclusion would be strengthened if the possible effect of extinction during training was eliminated. This paper is of interest to behavioural and neuroscience researchers studying learning, memory, and neural networks.

    1. eLife assessment

      This important study correlates the size of various prefrontal brain regions in primate species with socioecological variables like foraging distance and population density. The evidence presented in solid but needs to be strengthened with additional analyses that show the robustness of the results to delineation of the brain regions as well as including confounding variables like brain mass. Further the authors should clarify how this approach would generalize to lissencephalic primates which do not have the clear anatomical landmarks used in this study.

    1. eLife assessment

      This important study reports vastly different object recognition performance in rats and humans using comparable and rigorous behavioural testing, showing that rats performance is driven by low-level visual features whereas human performance is driven by more complex features. The evidence in support of these claims is intriguing but incomplete, and additional analyses are needed to elucidate the visual features that drive these differences and investigate inter-individual variability. The authors also need to acknowledge and discuss other factors such as visual acuity and training paradigm (extensive training on only two objects) that could have led to these different patterns of performance.

    1. eLife assessment

      This study presents valuable findings on the impact of C-natriuretic peptide (CNP) treatment in vivo on the fertility of aged mice. Solid data indicate CNP induces the cAMP-PKA pathway, causing reduced recruitment of Parkin protein to mitochondria in oocytes, resulting in reduced mitophagy which may be significant for increased mitochondrial bioenergetics and improved cytoplasmic and nuclear maturation. The authors make additional claims regarding the mechanisms by which CNP impacts oocyte quality in vivo for which the evidence is incomplete. This work will be of interest to reproductive biologists and clinical infertility specialists.

    1. eLife assessment

      This study explores how Ebola virus evades human immune responses. The study reports a potential new mechanism wherein Ebola virus traps human IRF3, a key transcription factor involved in immune signaling, into virus-produced "inclusion bodies." While overall the topic is important and the paper has many merits, readers should note that the reviewers identified some flaws in the experimentation, analyses, and description of methods, which means the strength of evidence is currently incomplete.

    1. eLife assessment

      The presence or absence of a surrounding envelope, previously a clear distinguishing feature of different viruses, has been blurred by the recent recognition that many so-called 'nonenveloped' viruses are released from cells as quasi-enveloped virions cloaked in host cell membranes. This mechanism of viral egress allows for non-lytic infection, and has potentially important implications for pathogenesis. In this manuscript, Jassey and colleagues provide solid evidence that the protein deacetylase SIRT-1 is required for the non-lytic release of enteroviruses in extracellular vesicles.

    1. eLife assessment:

      Autosomal dominant optic atrophy (DOA) in humans is associated with mutations in OPA1, a mitochondrial dynamin like GTPase. This study uses Drosophila as a model to recapitulate some aspects of the disease phenotype, and it supports and extends previously published data to provide valuable findings that have theoretical or practical implications in the field of rare retinal diseases. The approaches used are solid and allow to investigate differences between mutations that are supposed to be loss-of-function or acting as dominant negative with consequences in the optic system or in a version of DOA, in which other tissues are also affected. However, the main claims are only partially supported and additional information in the materials and methods and several figure legends is needed to complete the study.

    1. eLife assessment

      This study presents convincing evidence that metabolite levels in Escherichia coli bacteria from a long-term evolution experiment have changed in consistent ways, which in turn can be explained by recurrent mutations in regulatory genes that affect enzyme expression levels. The use of high-resolution mass spectrometry measuring bulk metabolite levels, in combination with existing gene expression and DNA sequencing datasets provides valuable information linking changes in an organism's genome, transcriptome, and metabolome.

      This study presents a computational model to explore how neurostimulation could impact hippocampal theta oscillations. The computational model combines a detailed physiologically realistic hippocampus model and an abstract theta oscillator. If confirmed, the study could be a useful tool that provides useful predictions on pathological changes in this network. The modelling is based on solid approaches that could be significantly improved with experimental validation.

      This important paper provides new insight into how asexual reproduction can arise in interspecific hybrids, an empirical example of the "extended speciation continuum." The molecular cytogenetic evidence supporting the conclusions is solid, but additional replicates within each species would strengthen the overall findings. By highlighting the potential for asexuality to evolve in hybrids during a narrow window of species divergence, this work will be of broad interest to evolutionary biologists.

      This manuscript presents a valuable analysis of allosteric communication in the CFTR protein using a coarse-grained dynamic model and characterized the role of disease-causing mutations. Some of the results are convincing and make a contribution to understanding the mechanism of CFTR, the discussion of the allostery mechanism is incomplete. Further discussion and validation of the computational approach will help strengthen the manuscript.

      This study presents findings on changes in brain network asymmetry in infants with congenital hearing loss. The findings are valuable but the evidence supporting the claims is incomplete and needs more appropriate and strict statistical analyses. The findings will be of interest to psychologists, neuroscientists, and clinicians.

    1. eLife assessment

      This paper reports the fundamental discovery of a new function of neutrophil in specifically clearing apoptotic hepatocytes by penetrating the cells rather than engulfing them without causing inflammation as a part of tissue homeostasis. This solid study transforms the way we think about role of neutrophil in pathogenesis of autoimmune liver disease.

    1. eLife assessment

      The authors present "MotorNet", a useful software package to train artificial neural networks to control a biomechanical model of an effector. The manuscript provides solid evidence that MotorNet is easy to use and can reproduce past results in the field, both at the neural and behavioural levels. Validation is limited to planar arm-like plants or point-masses, so future work exploring three-dimensional movements and other types of plants would strengthen the impact of the tool.

    1. eLife assessment

      This study presents a valuable set of findings on how prior expectations modulate tactile sensory processing. The neuroimaging evidence supporting the main conclusions is solid, although the nature of the experimental task somewhat limits the interpretation of the findings. This work will be of interest to neuroscientists working on sensory processing and perception.

    1. eLife assessment

      This useful study investigated the appearance of a "new-type" ultrasonic vocalization around 44 kHz that occurs in response to prolonged fear conditioning in rats. While the descriptive approach applied may be of interest to some researchers, evidence in support of the conclusions is incomplete.

    1. eLife assessment

      Using sophisticated reinforcement learning modeling, authors provide a valuable and convincing result that acute ketamine reduces the strength of the impact of losses vs neutral/gains on performance of a token-based matching-pennies task. However, authors provide incomplete evidence that this interesting acute effect may be a mechanism whereby ketamine is a rapid-acting antidepressant.

    1. eLife assessment

      This study involves a valuable investigation of habit-learning in obsessive-compulsive disorder versus controls with participants engaging in a month of motor-sequence task practice administered via a smartphone app. Currently the results are inadequate to support the authors' key claims as not all of the criteria were met to establish that habit learning occurred.

    1. eLife assessment

      This study provides a valuable contribution to the study of eye-movements in reading, revealing that attention-weights from a deep neural network show a statistically reliable fit to the word-level reading patterns of humans. Its evidence is solid and strengthens a line of research arguing that attention in reading reflects task optimization, although the work may further benefit from a more specific attribution of the predictive power of the models. The work would be of interest to psychologists, neuroscientists, and machine learning researchers.

    1. eLife assessment

      This fundamental study has successfully identified four key transcription factors (MECOM, PAX8, SOX17, and WT1) that exhibit synergistic effects and are potentially responsible for the transformation of fallopian tube secretory epithelial cells into high-grade serous 'ovarian' cancer cells. Convincing data strongly support the drawn conclusion and significantly contribute to our understanding of the etiology of this devastating cancer. The implications of this finding are substantial, as it provides valuable molecular insights that can potentially pave the way for innovative diagnostics and therapeutics in the field of gynecological oncology. Enhancing the clarity and impact of this study would be achieved through improvements in data presentation.

    1. eLife assessment

      This useful study identifies several gain-of-function division protein variants that can suppress the lethality caused by depletion of Aeg1/AdvA in Acinetobacter baumannii, but characterization and description of AdvA in its localization patterns and interactions with other divisome proteins are inadequate. Since a role of AdvA in cell division has been shown before, the claim that a "novel cell division protein" has been identified is incorrect. The evidence provided also does not support the claim that AdvA plays a critical role in the assembly of the A. baumannii divisome.

    1. eLife assessment

      This study has uncovered some important initial findings about how certain extracellular vehicles (EVs) from the mother might impact the energy usage of an embryo. While the study's findings are in general solid, some experiments lack statistical power due to small sample sizes. The study's title might be a bit too assertive as the evidence linking maternal mtDNA transmission to changes in embryo energy use is still correlative.

    1. eLife assessment

      This study presents a valuable finding on variations within the RNA synthesis protein of SARS-CoV-2, the virus that is responsible for COVID 19. The evidence supporting the claims of the authors is solid, although a more in-depth analysis of the structures and simulations would have strengthened the conclusions of the work. This work has implications for drug design and will be of broad interest to the general biophysics and structural biology community.

    1. eLife assessment

      In this valuable paper, the authors use an existing theoretical framework relying on information theory and maximum entropy inference in order to quantify how much information single cells can carry, taking into account their internal state. They reanalyze experimental data in this light. Despite some limitations of the data, the study convincingly highlights the difference between single-cell and population channel capacities. This result should be of interest to the quantitative biology community, as it contributes to explaining why channel capacities are apparently low in cells.

    1. eLife assessment

      This study presents a novel fluorescence based imaging strategy to investigate the folding status of RNA-binding proteins (RBPs) and their association with molecular chaperones under stress. It provides fundamental findings that will potentially advance our understanding in the folding and aggregation status of RBPs in nuclear stress bodies in a significant manner. However, there is also the concern that the evidence regarding protein fate is incomplete and additional controls are needed to fully support the conclusion. The imaging methodology can be adapted to study many other proteins that undergo liquid-liquid phase separation under specific cellular conditions.

    1. eLife assessment

      This study assesses homeostatic plasticity mechanisms driven by inhibitory GABAergic synapses in cultured cortical neurons. The authors report that up- or down-regulation of GABAergic synaptic strength, rather than excitatory glutamatergic synaptic strength, is critical for homeostatic regulation of neuronal firing rates. The reviewers noted that the findings are potentially important, but they also raised questions. In particular, the evidence supporting the findings is currently incomplete and demonstration of independent regulation of mEPSCs and mIPSCs is a necessary experiment to support the major claims of the study.

    1. eLife assessment

      The manuscript represents an important study on the pathogenesis of rubella virus tropism and neuropathology in human microglia-containing human stem cell derived organoids and human fetal brain slices. The strength of evidence is compelling, employing two different human-relevant models. The findings will be of broad interest to virologists and infectious disease experts, as well as neurodevelopmental biologists. The findings could also be of interest to pediatrics and obstetrics clinical colleagues.

    1. eLife assessment

      This manuscript describes important findings that will impact our understanding of nuclear pore complex (NPC)-genome interactions and how nuclear pore proteins (nucleoporins) impact super enhancer function. The authors develop a clever new approach termed NPC-DamID to map chromatin-NPC interactions that has several important advantages over existing techniques and may be used in contexts that are incompatible with genetic manipulation. The authors provide compelling evidence that nucleoporins interact with super enhancers in multiple cell types and also suggest that the phase separation behavior of nucleoporins contributes to the hierarchical organization of super enhancers, which is exciting and will stimulate additional work.

    1. eLife assessment

      This study addresses the long-standing question as to how different functional pools of synaptic vesicles are organized in presynaptic terminals to mediate different modes of neurotransmitter release. Based on imaging of active synapses with recycling synaptic vesicles labeled by FM-styryl dyes, the authors provide data that are compatible with the hypothesis that two separate reserve pools of vesicles - slowly vs. rapidly mobilizing - feed two distinct releasable pools - reluctantly vs. rapidly releasing. Overall, this study represents a valuable contribution to the field of synapse biology, specifically to presynaptic dynamics and plasticity. However, the authors' methodological approach of using bulk FM-styryl dye destaining as a readout of precise vesicle arrangements and pools in a population of functionally very diverse synapses has limitations. Consequently, the evidence that directly supports the authors' two-pool-interpretation of their data is incomplete, and alternative interpretations of the data remain possible.

    1. eLife assessment

      This is an important study that demonstrates a role of the murine thalamus in ocular dominance plasticity. The evidence supporting the authors' claims is solid, although the inclusion of a conditional KO in which synaptic inhibition was only interfered with in adulthood could better support the authors' conclusions. This work will interest those in the field of ocular dominance plasticity in the visual system as well as scientists investigating the function of synaptic plasticity in the brain.

    1. eLife assessment

      The bacterial neurotransmitter:sodium symporter homoglogue LeuT is an well-established model system for understanding the fundamental basis for how human monoamine transporters, such as the dopamine and serotonin, couple ions with neurotransmitter uptake. Here the authors provide convincing data to show that the K+ catalyses the return step of the transport cycle in LeuT by binding to one of the two sodium sites. The paper is an important contribution, but it's still unclear exactly where K+ binds in LeuT, and how to incorporate K+ binding into a transport cycle mechanism.

    1. eLife assessment

      This important study examines whether synaptic cell adhesion molecules neuroligin 1-3 resident on astrocytes, rather than neurons, exert effect on synaptic structure and function. With convincing evidence, the authors report that deletion of neuroligins 1-3 specifically in astrocytes does not alter synapse formation or astrocyte morphology in the hippocampus or visual cortex. This study highlights the specific role of neuronal neuroligins rather than their astrocytic counterparts in synaptogenesis.

    1. eLife assessment

      This valuable study investigates how hierarchies are processed in the brain, using a paradigm that intends to bridge disparate domains (e.g., language/music and memory). The main findings are that hippocampus and medial prefrontal cortex are sensitive to hierarchy position, while the response in inferior frontal gyrus seems to vary with amount of experience with the hierarchy. Evidence supporting these claims is solid, and would be strengthened by additional methodological clarifications (e.g., as to why the particular analyses are most appropriate for the research question) and further discussion of limitations related to the study design (e.g., the possibility that the task does not require hierarchical representations).

    1. eLife assessment

      This manuscript describes a fundamental strategy for developing isozyme-selective inhibitors of inositol hexakisphosphate kinases. The compelling evidence that subtle changes to the gatekeeper position can sensitize the inositol hexakisphosphate kinase mutant to allosteric inhibitors will undoubtedly inspire other analog-sensitive inhibitor studies. This manuscript will be of interest to researchers focusing on kinase regulation and inhibitor design.

    1. eLife assessment

      The authors pair single-cell sequencing technology with the LoopSeq synthetic long-read method to examine samples of hepatocellular carcinoma and benign liver, with the goal of identifying mutations and fusion transcripts specific to cancer cells. The authors present a valuable resource, but the overall support for the major claims remains incomplete. In particular, the authors could have provided stronger support for the combination of technologies and interpretation regarding cancer-associated genomic changes.

    1. eLife assessment

      The authors present valuable findings on how to determine the genetic architecture of extreme phenotype values by using data on sibling pairs. While the authors' derivations of the method are correct, the scenarios considered are incomplete, making it difficult to have confidence in the interpretation of the results as demonstrating the influence of de-novo or Mendelian (rare, penetrant-variant) architectures. The method shows nevertheless promise and will be of interest to researchers studying complex trait genetics.

    1. eLife assessment

      In this study, the authors discuss the relevance of the tumor mutational burden (TMB) as an appropriate predictive biomarker for the effectiveness of immunotherapy. The study offers important findings that will contribute to current dialogues around the biomarkers used for therapy in cancer (and perhaps, other diseases). This is an area of substantial controversy, and the authors have gone to great lengths to support their claims with convincing evidence.

    1. eLife assessment

      This work presents valuable findings on the cellular and ultrastructural organization of the nervous system in the freshwater polyp Hydra.

    1. eLife assessment

      This important study reports on a novel read-out methodology and fabrication strategy to mimic nuclear pore complexes, without the drawbacks of usual techniques, revealing a clear correlation between the size of the nuclear pore complex mimic and its transport selectivity. The methods are compelling, and the data, analyses and interpretation with coarse grained simulations and phenomenological models are solid, supporting the claims with minor weaknesses that would benefit from further clarification. This approach has important potential implications for further understanding of transport by the Nuclear Pore Complex.

    1. eLife assessment

      This valuable study examines the effects of different co-stimulatory pathways on gene expression and chromatin accessibility in T cells, in order to link the role of co-stimulatory proteins to genetic variants associated with inflammatory bowl disease (IBD). The work provides valuable insight into the role of alternative co-stimulatory proteins in controlling T cell responses. However, the data presented and the analyses performed are still incomplete and inconclusive with regards to IBD risk factors.

    1. eLife assessment

      The authors present a useful analysis of the phenotype of sheep in which the muscle developmental regulator myostatin has been mutated in a FGF5 knockout background. The goal was to produce sheep with a "double-muscled" phenotype, yet the genetically engineered sheep exhibited meat with a smaller cross-sectional area and higher number of muscle fibers. The work extends the extensive body of knowledge already published in this area. The authors provide evidence using in vitro experiments that Fosl1 regulates myogenesis, but the strength of evidence relating to the muscle phenotype and underlying cellular and molecular mechanism is inadequate.

    1. eLife assessment

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

      This paper will be of interest to scientists in the fields of virology, entomology, ecology and epidemiology as the paper explores the drivers of viral and host composition in natural and disturbed ecosystems. The data are of high quality and have been rigorously assessed.However, important additional information on the transmission ecology of these viruses and their relationship with the environment is lacking, making it difficult to interpret the results from a disease ecology perspective.

    1. eLife assessment

      The authors compellingly demonstrate that k-fiber length and dynamics are regulated at the level of individual fibers, even in the absence of focused poles, but that unfocused spindles fail to accurately segregate chromosomes, suggesting that coordination of k-fiber length by pole focusing is important for spindle function. This study provides important new information on spindle scaling, extending in an original manner previous work on this topic.

    1. eLife assessment

      This valuable paper uses representative samples of micro-census data from Botswana to describe migration rates over four points in time, from 1981 to 2011. The authors use compelling descriptive data to present migration characteristics where roughly 10% of the population moved in the past year - with equal numbers of men and women, and with migration between districts more common than within districts. Preliminary data indicated migration patterns could have supported HIV diffusion, this can be a starting point for more in-depth analyses. The work will be of interest to those studying human movement and its impact on diseases.

      This important study gives novel insight into the folding diversity of the cerebellum compared to the cerebrum among 56 mammalian species. Based on impressive data, the analyses performed for anatomical descriptions and phylogenetic comparisons are solid, although some issues need to be addressed regarding the choice of statistical models, and the sample size versus the number of explanatory variables. This study will be of interest to neuroscientists, evolutionary and developmental biologists, and physicists interested in biomechanics, as these observations provide a basis for models of brain folding mechanisms.

    1. eLife assessment

      This study presents valuable findings that relate the pH pattern along the root surface of the plant Arabidopsis thaliana to the auxin response and gravitropic (changes in growth orientation) response. The evidence supporting the claims of the authors is solid, based on the observation of dynamic responses at a second-to-minute time scale and the systematic correlation between the observed changes in the longitudinal surface pH profile and changes in growth rate. The work will be of interest to a wide range of plant biologists working on plant development and responses to the environment.

    1. eLife assessment

      This paper studies color vision in anemonefish. The central conclusion of the paper is that anemonefish use signals from their UV cones to discriminate colors that would not otherwise be distinguishable; this differs from other fish in which UV cones extend the range of wavelengths of sensitivity but do not add a dimension to color vision. The work fits into a rich history of studies investigating how color vision fits into an animal's ecological niche. At the same time, the manuscript needs to more clearly establish and convey the degree to which each conclusion is supported by the data and where the limits of certainty lie.

      This manuscript presents a valuable new microfluidic tool that will allow researchers from different fields to rapidly quantify the chemotactic response of microbes to chemical gradients that have different strengths. Using planktonic bacteria, this paper convincingly shows that a multiplexed microfluidic device produces similar results to previously described microfluidic devices that generate only one gradient at a time. By performing on-chip dilutions, this device allows data for six different gradient strengths to be generated simultaneously, potentially reducing both experimental effort and biological variability.

    1. eLife assessment:

      This manuscript uses an innovative combination of spatial profiling with single-cell transcriptomics to define expression profiles of stromal components in proximal tumor regions compared to those in distal regions in pancreatic ductal adenocarcinoma (PDAC). Based on this, the authors claim that the presence of a proximal fibroblast population predicts worse outcomes for PDAC patients than the presence of a distal fibroblast population. While the work provides valuable insight into how different types of tumor stromal fibroblasts may affect PDAC outcomes, the work is currently incomplete and will benefit from more extended use of fibroblast and myeloid cell markers and efforts to better define the transcriptomic data generated.

      This study of human perceptual decision-making provides important insights into the sources of suboptimality in human inference. The authors provide solid evidence by combining psychophysics in an audiovisual causal inference task with detailed modeling of the observed behavior. Additional control analyses should be carried out to validate the identifiability of distinct suboptimalities using the authors' modeling framework, and the generalizability of their findings in other conditions should be tested or discussed more explicitly.

    1. eLife assessment:

      This important study convincingly shows that the endopeptidases ECS1 and ECS2 repress the formation of polyspermy-derived triparental offspring and haploid induction by promoting double fertilization. While the underlying mechanisms remain to be further elucidated, the data presented in this study represent a valuable foundation for understanding the regulation of offspring genome size. This study will be of particular interest to the large community of scientists who are interested in plant reproduction and breeding.

      This study presents valuable structures of a pentameric ligand-gated ion channel from a thermophilic worm that is a homologue of the well-known mammalian nicotinic receptors. Although the function of the worm receptor is unknown, the authors convincingly identify interesting features for this class of receptors including a steroid detergent that is bound in the canonical neurotransmitter site and that induces conformational changes of the extracellular domains. These observations will be of broad interest to the ligand-gated ion channel community, although it is difficult at this moment to relate these observations to channel function as the channel's activating ligand remains unknown.

    1. eLife assessment

      This research provides convincing evidence that standard behavioral modeling and EEG-derived signatures of the decision process may not agree on mechanisms underlying changes in decision strategy. The authors make a strong case for the importance of informing behavioral modeling with putative neural signatures of the corresponding decision processes. The assumptions of this neurally-informed modeling approach should be further explored and clarified to highlight not only its benefits but also potential caveats.

    1. eLife assessment

      Models of cerebellar function and the coding of inputs in the cerebellum often assume that random stimuli are a reasonable stand-in for real stimuli. However, the important contribution of this paper is that conclusions about optimality and sparseness in these models do not generalize to potentially more realistic sets of stimuli, for example, those drawn from a low-dimensional manifold. While the mathematical modelling and analysis in the paper are convincing, one important limitation of the paper is that the neural dynamics and circuit architecture are not very specific to the cerebellum, and lack important biological detail.

      This manuscript by Combe et al. presents the role of cholinergic modulation in the spike rate adaptation in pyramidal place cells. Using combined electrophysiology, pharmacological, and multi-compartment computational modeling, the authors identify the downstream pathway (e.g. activation of TRPM4 channel) that shapes the firing pattern under the triangular-shaped ramps. The study demonstrates solid evidence, and the findings are important for bridging pyramidal neurons' molecular/channel properties to behavior-level implications (place field firing).

      This important work studies the spontaneous contractions (SC) of the Hydra body wall and presents a mathematical model of nutrient transport to hypothesize the role of SC on maintaining the microbiota. The solid evidence presented yields insights on the functional implications of the SC and the increased nutrient update obtained from mixing the local fluid environment through body wall contractions. The main result represents an important observation about the role of hydrodynamics on organism behavior and its relation to diffusive chemical transport processes.

      The manuscript by Brunetti et al. represents an important contribution where SARS-CoV-2 infection of T-helper cells is implicated and found to be mediated by CD4. The work progressed through a computationally driven hypothesis, by analyzing the interaction partners of SARS-CoV-2 spike glycoprotein (as initially modelled through similar SARS-CoV-1), followed by experimental validations, and further computational and experimental insights on the mechanism of binding. The study identifies the interaction between spike RBD domain and N Terminal domain of CD4 molecule as the specific viral attachment strategy. The evidence supporting the claims of the authors is solid, the results look significant and the data is clear and enough for understanding the manuscript. It also provides a potential usefulness of their approach in future work in understanding how viruses mediate infection of T cells. The work will be of interest to medical biologists working on SARS-CoV-2.

      This fundamental work advances our understanding of the effects of metformin on bone healing in hyperglycemic conditions. The evidence supporting the conclusion is convincing, using three different types of bone fracture models in type-2 diabetes (T2D) mice. This paper is of potential interest to skeletal biologists, orthopaedic surgeons, and endocrinologists who study the effects of metformin on fracture healing.
