      This valuable study reports improvements in methods and tools for curating complex pathogen-host interactions. A compelling framework is described, using rigorous approaches and to considerable extent validated by the biocuration community. The developed ontologies and controlled vocabularies could be extended beyond host pathogens, e.g. ecological contexts with multi-species and multilevel interactions.

      This work presents a multimodal approach to ascertain links between risk and resilience to depression and Alzheimer's disease in a large pediatric sample. The authors find two latent imaging variables that may be associated with resilience to adverse life events and disease risk, which show some spatial overlap with disease relevant gene-expression patterns and neurotransmitter expression. Such findings could be important for understanding mechanisms underlying resilience in neurological disorders, however, the analyses are inadequate for fully supporting the interpretation of the variables involved in these models, or for supporting some of the overall conclusions of the work.

      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.

      This useful study uses untargeted metabolomics to help us understand how some herbivores are able to be generalists, rather than specializing in the metabolism of specific plant species. This is an important area, since little is known about how generalist insect species metabolize their food. In its current form, the study lacks ecological relevance due to the exclusive use of refined sampling procedures, and the metabolomic analysis is incomplete.

      This important study should be of interest to vision scientists and those seeking to model naturalistic image processing for humans in simulated or real navigational [walking] situations. The experiments aim to provide information about the statistics of "retinal" motion patterns generated by human participants physically walking a straight path in real terrains that differ in "smoothness". State-of-the-art eye, head, and body tracking allowed simultaneous assessment of eye movements, head movements, and gait, with convincing evidence for an asymmetrical gradient of flow speeds during walking, tied predominantly to vertical gaze angle, together with a radial motion direction distribution tied most critically on horizontal gaze angle. While not a major weakness per se, additional details on analytical methods used and estimations of variance across observers would strengthen these results and clarify the basis of the global claims made about visual motion information across the visual field in walking humans.

    1. The central question of the Anthropocene, why did behaviorally modern humans gain the unprecedented capacity to change an entire planet, cannot be answered by genetic changes in human behavior. To explain why human societies scaled up to become a global force capable of changing the Earth and why there are so many different forms of human societies and ecologies shaped by them, explanations must be sought beyond the theories of biology, chemistry or physics. Here I introduce a new evolutionary theory, sociocultural niche construction, aimed at explaining the origins of human capacity to transform the Earth 3. As will be seen, this theory also explains why behaviorally modern human societies came to transform ecology in so many different ways over the past 50,000 years as they expanded across the Earth.

      This valuable study provides solid results on the molecular signaling mechanisms of CaM kinase kinase-1 (CKK-1) in the context of the nociceptive behaviors of C. elegans. The authors report previously undescribed elements that control the nuclear/cytoplasmic shuttling of CKK-1, suggesting a complex interplay of multiple nuclear localization and export sequences. Therefore, the work will be of broad interest to scientists studying behavior, neuronal signaling, and signal transduction in general.

      This important study proposes a phenomenologically motivated theoretical framework to explain observed patterns of the temperature dependence of microbial diversity. The methodology is overall convincing, but the explanations of approximations and assumptions, and of their regime of validity, are incomplete. The manuscript should be of interest to microbial ecologists.

      In this study, the authors made important progress in understanding bone metabolic defects of T2D. They have established a valuable model that could mimic some aspects of T2D in mice. Particularly, the study provided important evidence showing bone turnover and metabolism were in defects, and changes in glycolysis would rescue bone defects in T2D. Overall, the authors provide compelling evidence from dynamic histomorphometry, C13 isotype labeling in vivo, scRNA-seq, and metabolic assays to demonstrate that the defective glucose metabolism causes osteopenia associated with T2D.

      The current study provides important, mechanistic insight into the potential contribution of antisense C4G2 expanded RNA to disease in C9orf72-associated ALS/FTD. The authors convincingly demonstrate that expression of this RNA species activates the PKR/eIF2α-dependent integrated stress response. They further provide evidence that this can contribute to disease phenotypes using multiple models and post-mortem patient samples.

      This important study reports a unique N-terminal motif of Staphylococcus aureus GpsB and the co-crystal structure of GpsB with the C-terminus of PBP4. It provides convincing evidence demonstrating the interactions of GpsB with PBP4 and FtsZ, shedding light on the role of GpsB in the pathogen's cell division. However, the functional characterization of GpsB's new motif caused and the structural characterization of GpsB and FtsZ's interaction is incomplete.

      This fundamental work shows the absence of links between striatal dopamine synthesis capacity and working memory capacity, spontaneous eye-blink rate, and trait impulsivity. The evidence supporting the conclusions is compelling, with rigorous PET investigations and state-of-the-art cognitive assessments in a large sample. Given the high interest in the role of dopamine, the work will be of very broad interest to basic neuroscientists, clinical neuroscientists, and clinicians including neurologists and psychiatrists.

    1. eLife assessment

      This important manuscript describes a series of cellular phenotypes associated with the depletion of TANGO2, a poorly characterized gene product but relevant to neurological and muscular disorders. The authors present solid data indicating that TANGO2 associates with membrane-bound organelles, mainly mitochondria, impacting lipid metabolism and the accumulation of reactive-oxygen species. A few additional experiments would help to understand the link between the lipid changes reported and the cellular phenotype.

      The paper is of interest to neuroscientists, developmental biologists, and those interested in mechanisms that underlie intellectual disability. The study is well executed and brings new insight into the role of WDR62 and its role in causing microcephaly. The key claims of the manuscript require additional data.

    1. eLife assessment<br /> <br /> This work provides a valuable allele-specific gene editing therapeutic approach to selectively target the human RHO-T17M mutation, one of the most frequent genetic causes of autosomal dominant retinitis pigmentosa. However, the current data are incomplete. Further validation of gene editing efficiency in rods at cellular level in vivo and use of Rho-T17M mice will strengthen the conclusion.

    1. eLife assessment

      The present manuscript addresses the controversial issue of the regeneration potential of cerebellar Purkinje cells in zebrafish and their integration into functional circuits. The authors use interesting genetic models to induce Purkinje cell-specific ablation to demonstrate regeneration of Purkinje cells can occur until adulthood and is accomplished by ptf1a+ progenitors. They further show that regenerated neurons reestablish electrophysiological properties and support appropriate behavior. These are important results that may help understand why mammalian neurons do not have similar properties and fail to regenerate. The conclusions on the source of regenerated neurons will however need additional experimental support.

      In this manuscript, Gonzalez et al investigated the dynamics of dopamine signals in the lateral shell of the nucleus accumbens (LNAc) in response to different types of carefully defined visual stimuli. Contrary to reigning theories of dopamine signaling, the authors presented convincing evidence that LNAcc dopamine transients tracked visual sensory transitions rather than any immediately apparent motivational variable. These important findings based on compelling evidence point to a potentially new role for dopamine signaling in the ventral striatum.

      Based on the Cryo-EM structure of human ETB in complex with the vasoconstricting peptide ET-1 and the inhibitory G-protein (Gi), this valuable study presents convincing data on how agonist binding is coupled to Gi-protein binding. The complex structure is solid and will appeal to the GPCR and pharmacology communities.

      Nearly all organisms require a ribonucleotide reductase (RNR) to convert ribonucleotides to their deoxyribonucleotide counterparts. In this important study, the reader learns how the model organism Escherichia coli can adapt to survive without any of its three RNRs. Compelling microbiology experiments to develop this model and analysis of compensatory mutations reveals patterns that are conserved in the few known pathogens that have also eliminated their dependence on an RNR. The manuscript will be of interest to microbiologists, biochemists, and those who work on the evolution of microbial metabolism.

      This work provides a promising first pass at providing an integrative model for how decisions arise from neural circuits. The approach is novel but lacks a more rigorous vetting against alternative model formulations to be able to determine its true significance. More stringent evaluations of the model in the context of existing work, as well as a clearer description of the goals and implementation of the approach, would help to address these concerns.

    1. eLife assessment

      The study represents an impressive effort to use atomistic simulations to probe cryptic binding sites in the envelope of six flaviviruses. Moreover, using constant pH simulations, the authors suggest that a cluster of ionizable residues contribute to the pH dependent conformational rearrangements required in the infection process. Therefore, the study provides new mechanistic insights that can be helpful in future efforts to develop drugs that target flaviviruses.

    1. eLife assessment

      This is an important study that investigates the impact of tyrosine kinase inhibitors (TKIs) in chronic myeloid leukemia. Through a combination of pre-clinical in vivo measurements, clinical data, and computational modeling, the authors present solid evidence regarding the heterogeneous effects of TKIs in patients and how the response to treatment may be improved. With the assumptions about differences between normal and leukemic cells addressed, this study would be of interest to those working in the fields of mathematical oncology and cancer biology.

    1. eLife assessment

      The authors revisit fundamentals of synaptic transmission using a combination of advanced optical methods capable of visualizing calcium influx and neurotransmitter release at single release sites. By doing so, the authors present evidence for silencing of neurotransmitter release at single release sites as a function of external calcium. The data have relevance to a wide range of phenomena including neural plasticity and inhibitory modulation of synaptic communication.

    1. eLife assessment

      This important study presents a machine learning-based classifier that can accurately determine the geographic origin of a Salmonella enterica sample from its whole-genome sequencing data in under five minutes leading to actionable public health insights. Applying the method to 2,313 whole genome sequences collected in the United Kingdom and several external validation datasets, the authors provide convincing evidence that Salmonella genomic data can be used to identify the likely geographic source of a food-borne outbreak and, in most cases, correctly identify the country of origin of an infection acquired overseas. The work presents an excellent case for the potential utility of routine genomics coupled with machine learning for public health microbiology and the methods are likely to be applicable to other pathogens besides Salmonella enterica.

    1. eLife assessment

      The findings in this study are important as they establish a rat model of a classic form of early-onset osteoporosis and demonstrate that osteoporosis medications are effective in the model. The evidence supporting the authors' claims is compelling.

    1. eLife assessment

      This important landmark paper identifies three distinct stellate ganglion nerve cell subtypes stratifiable in terms of their neuropeptide Y expression correlating these with gene expression and electrophysiological properties. Their innovative use of viral tracing techniques compellingly established their conclusions. This major contribution to cardiac sympathetic excitation is relevant to a wide scientific and clinical audience.

      This important work demonstrates a significant asymmetry between the connectivity statistics of the left and right hemispheres of the Drosophila larva brain. The evidence supporting the conclusions is compelling and represents a first step toward the development of statistical tests for comparing pairs of connectomes more generally. This work will therefore be of interest to the broad neuroscience community.

    1. eLife assessment

      This paper will be of interest to scientists involved in understanding the function of long non-coding RNAs. The authors found two genes previously reported as lincRNAs in early studies encode micropeptides in zebrafish. Zebrafish mutants lacking these micro-peptides show altered gene regulatory networks that preferentially affect oligodendrocytes and cerebellar cells in the embryonic brain. The data presented in the study are solid and present convincing additional evidence for the versatile functions of micro-peptides.

      This study is an important contribution to the understanding of Buruli ulcer transmission in Australia. The authors provide compelling evidence that the carriage of Mycobacterium ulcerans by possums, within their small home range, can predict cases of Buruli ulcer disease in individuals who visit those areas. While not directly relevant to the transmission of Buruli ulcer in West and Central Africa, the work will be of great interest to those studying the transmission of opportunistic environmental pathogens.

    1. eLife assessment

      This study employs live imaging to investigate the movement of mesodermal cells in early mouse embryos. By examining the dynamics of cell behavior in normal and mutant embryos, the authors propose that apical constriction of cells results from pulsed contraction guided by crumbs2 signals. The paper presents beautiful images and adds to the molecular understanding of cell migration during early development.

      In this Tools and Resources article, Sapiro et al. overcome the technical burden of low Borrelia burgdorferi numbers during infection by physically enriching for spirochetes prior to RNA-sequencing/mass spectrometry. This work is important as it provides technical advances for the study of global transcriptomic changes of B. burgdorferi during tick feeding and builds on the knowledge already collected by the field. The evidence presented is compelling, and the strategy described here could benefit researchers in the field and possibly support broader applications.

    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. While the main method used is state of the art and the supporting data are solid, the vigor of the biochemical assays and function validation is inadequate. This work will be of interest to developmental and reproductive biologists working on fertilization.

    1. eLife assessment

      This study provides valuable insights into the role of two under-researched sperm-specific proteins (Cylicin 1 and Cylicin 2). The authors provide convincing evidence that they have an essential role in sperm head structure during spermatogenesis, and that their loss leads to subfertility or infertility, with a dose-dependent phenotype. The authors identify infertile males with mutations in both Cylicin1 and Cylicin2: thus the findings from the mouse models might be applicable to understanding human male infertility with similar structural defects.

      Gordon-Fennell et al. present a low-cost, open-source platform for measuring action elicitation and consummatory behavior in head-fixed animals. The findings are important because they allow animals to perform a truly voluntary action whilst their head is held still, and the evidence supporting them is both comprehensive and compelling (in some cases even exceptional). The results have the potential to have a broad impact in the field as many labs start to move towards measuring head-fixed behavior effectively, although this is said with the caveat that such behavior will never be an ideal replication of naturalistic behavior.

      This manuscript describes an approach to creating fat tissue in culture for food applications. Specifically, the efforts of growing cultivated meat focus mostly on growing skeletal muscle. However, the taste component of such artificial meat would be determined by fat content. There is a significant desire and motivation to cultivate fat tissues in vitro for the purpose of the replacement of animal products. This paper provides new technological approaches to expand adipocytes and aggregate them into structures that resemble fat.

      This important manuscript employs a rigorous and multi-pronged comparative genomics approach to unravel how lifestyle modulates the acquisition and domestication of viral genetic elements in the genomes of hymenopteran insects. Using an extensive dataset of over 120 hymenopteran genomes, the authors provide convincing evidence that endoparasitism (where parasite development occurs within hosts) facilitates the uptake and domestication of double-stranded DNA viral elements.

      This valuable paper examines the effect of deiodinase polymorphism on thyroid hormone signaling in the brain by employing a transgenic animal model and then switching to studying T3 axonal transport using microfluid devices. Although methodologically extensive this paper has several claims that are not convincingly supported by the current experiments and furthermore some disjoint is observed between the two halves of the study. The therapeutic implications of understanding T3 signaling in the brain makes it a potentially important manuscript.

    1. eLife assessment

      The authors use analytic calculations and numerical simulations to convincingly show that the purported benefits of nonlinear decay in morphogen gradients may be marginal in some cases and completely reversed in others (far from the concentration source). This is a valuable contribution to the field, as it questions common assumptions about the biological function of non-linear morphogen decays during development.

    1. eLife assessment

      This important study presents valuable findings on the dissemination of plasmids. In an analysis of five major Enterobacterales genera, the authors convincingly demonstrate that similar plasmids are shared between genera, species, and clones, both within and between ecological niches. Given the size of the dataset and the very detailed level of analysis this study importantly contributes to insights into to the flow of plasmids, including those carrying antimicrobial resistance genes, across niches.

      The authors characterize an H3N2 influenza A virus that jumped from birds into dogs in 2006. Through its evolutionary adaptation to dogs, the virus is now gaining properties that are increasingly consistent with the potential to infect humans. Using experiments with canine H3N2 influenza isolates, the authors found that more recent viruses have acquired receptor specificity for both avian- and human-like receptors, enhanced low-pH stability and in vitro growth, as well as improved replication and transmission in the dog and ferret models.

    1. eLife assessment

      This valuable study reveals that patient-derived organoids recapitulate similar genomic signatures as that of the parental tissue, which could be a useful model to evaluate chromosome instability, drug sensitivity, and intratumoral heterogeneity. However, whereas some of the sequencing data are compelling, the theoretical analysis is incomplete and would benefit from a more rigorous definition. With the theoretical part strengthened, the work will be of interest to medical biologists working on ovarian carcinoma.

      Only few species of Leishmania, an important human pathogen, have an RNAi machinery, alternative methods are needed for genetic screens. The authors resent and validate a valuable method, based on the introduction of premature stop codons, that can be used for several different species. The results are very convincing, the data are solid, and the approach will be of interest to researchers studying any eukaryote that lacks the RNAi machinery.

      This convincing work reviews and synthesizes evidence of the impact of the COVID-19 pandemic on a variety of cancer outcomes. The results have potentially useful implications for various fields of cancer research as they review evidence spanning from cancer prevention efforts to changes in diagnoses and cancer treatment modalities.

    1. eLife Assessment:

      Mutations in a variety of intermediate filament proteins and their regulators lead to abnormal development, reduced lifetime, and increased stress sensitivity. This manuscript rigorously demonstrates that such defects result from inappropriate assembly of intermediate filament networks, as mutations in a central intermediate filament protein prevent assembly of both the normal network and these inappropriate assemblages and largely rescue most of the defects. This has important implications for our understanding of the assembly of intermediate filament structures and for understanding and potentially treating diseases resulting from mutations in intermediate filament protein genes.

    1. eLife assessment

      This important study significantly advances our understanding of the calcium signaling pathway mediated by the kinase CDPK1, in the protozoan parasite Toxoplasma gondii. The evidence supporting the authors' conclusions is in many parts convincing, with rigorous biochemical and microscopy analysis. The work will be of broad interest to researchers in the field of signal transduction and protozoan biology.

    1. eLife assessment

      This is an important study that asks why odors smell similar even though their chemical structures appear quite different. The authors use machine-learning to make a compelling case to map the odor-relatedness of compounds to their place in metabolic pathways and propose that this is a general feature of odor perception across the animal kingdom. The conclusions could be strengthened by considering published physiological data.

      Antibodies perform a critical function in host defense against viruses and have emerged as major therapeutic tools in modern medicine, as evidenced by the large scale use antibody-based therapies during the COVID-19 pandemic. This paper describes the characterization of human antibodies to hantaviruses that have the potential to create devastating epidemics. The results teach us about the viral structures that are targets for neutralization and the results are relevant for vaccine development and antibody therapeutic design.

    1. eLife assessment

      This study uses behavioral monitoring and cutting-edge calcium imaging approaches to track the activity of cholinergic and noradrenergic axons in cortex of head-fixed mice, and correlate activity with behavioral state. While the evidence that behaviorally related signals are broadly broadcasted to the dorsal cortex is clear from the data, the conclusion that there is also heterogeneity across axons and areas is of less certain significance and might be undermined by methodological artifacts.

    1. eLife assessment

      In this work Frantz et al. assess transcriptomic states of melanocyte stem cells that are recruited to differentiate during the process of melanocyte regeneration in zebrafish and they analyze roles for Kit signaling in this process. The analyses are nicely done, and the paper requires only relatively minor modifications and clarifications. The study will provide new insights into melanocyte stem cell biology that should be of interest to those studying pigmentation, regeneration, and melanoma biology using zebrafish and other systems.

    1. eLife assessment

      This important study employs auxin-induced degradation to show that the TATA-binding protein (TBP) is not required for ongoing RNA polymerase II transcription nor heat-shock or retinoic acid-induced transcription, but that TBP is essential for RNA polymerase III transcription, with TBP-independent TFIID complexes being assembled and present at the transcription start sites of polymerase II-transcribed promoters. The evidence for the major claims is currently incomplete.

    1. eLife assessment

      The authors have developed a useful and user-friendly software to analyse gene expression data from four datasets representing premalignant lung lesions. This software would be of interest to those working in lung cancer and specifically the pre-malignant space. The major strength is the ease of use while the major limitation is the inability for the user to integrate other datasets.

      Determination of the biomechanical forces and downstream pathways that direct heart valve morphogenesis is an important area of research. In the current study, potential functions of localized Yap signaling in cardiac valve morphogenesis were examined. However, the evidence for Yap pathway activation and localization relative to areas of the valve subject to different mechanical stresses is not convincing.

    1. eLife assessment

      This is a well-explained and potentially useful study that describes the generation and use of pYtags, recombinant proteins that, if properly used, should allow spatiotemporal monitoring of the activation of different receptor tyrosine kinases in living cells. Although this study has generated new tools to evaluate receptor localization and activation in different cells, the broad concept showing that different receptor dimers generate specific stimuli, and downstream signaling pathways, is quite limited in terms of novelty. Although it is felt that the study is technologically innovative, the analysis of receptor spatial signaling is incomplete and should be improved.

      This fundamental study substantially advances our understanding of the process of ribosome maturation. The authors have purified and determined the structures of several nucleolar ribosome assembly intermediates in yeast using cryo-electron microscopy (cryo-EM). The study combines genetic, biochemical, and structural analysis to provide compelling support for the conclusions the authors wish to draw. The work will be of broad interest to cell biologists, biochemists, and structural biologists.

    1. eLife assessment

      This is an intriguing study investigating the molecular mechanisms of neural circuit developmental organization. Using a defined hippocampal circuit, the authors find that ectopic expression of an adhesion G protein-receptor leads to axon mistargeting. This work defines new mechanisms of axon target specificity.

      Russel et al. study and reveal compelling evidence for potential sequence-based factors that may drive VDJ trimming, a mechanism involved in VDJ recombination that shapes adaptive immune repertoire generation. The work is based on a rigorous statistical comparison of logistic regression models to reveal the role and function of cutting enzymes in shaping T- and B-cell receptor diversity. It could provide fundamental new insights into these processes with some claims being currently incomplete.

    1. eLife assessment

      This study investigates the spatiotemporal characteristics of human brain activities during object recognition under noisy and ambiguous conditions. By using state-of-the-art data analysis and model-driven fusion of MEG and 7T, this work demonstrates distinct representational profiles in ventral and dorsal pathways, contributing new perspectives to our understanding of the neural implementation of object recognition under uncertainty.

      Siglec-1 (CD169), a plasma membrane-associated sialic acid-binding lectin, has been implicated in the capture of HIV and other viruses by dendritic cells and macrophages. However, the molecular details of how HIV particles are captured by Siglec-1 are poorly understood. In this paper, the authors use advanced imaging methods to analyse the cell surface distribution of Siglec-1 on immature and mature dendritic cells to study the regulation of Siglec-1 distribution by actin and regulators of actin polymerization and to understand how virus-Siglec-1 engagement leads to virus sequestration within so-called virus containing compartments. These types of analyses have only recently become feasible with the implementation of super-resolution imaging and as yet few virus-host cell systems have been examined in detail. Thus, this study has relevance for researchers studying the engagement of HIV and many other viruses with cells, as well as researchers interested in the mechanisms regulating receptor distribution and function on cells.

      Poison frogs sequester alkaloids to make themselves toxic or unpalatable to predators, but how this sequestration occurs is not well understood. This valuable study identifies an alkaloid-binding protein in the plasma of poison frogs, which may help explain how these animals are able to sequester a diversity of alkaloids with different target sites. The supporting evidence is solid and the study adds to our understanding of how toxic animals resist the effects of their own defenses.

      Elbaz-Hayoun et al. investigate the role of macrophages in the gliotic response of retinal Müller glia and photoreceptor cell death. The authors find that macrophages play a role in inducing retinal damage. A role for the muller glia expressed, C-C chemokine receptor axis was identified as a causative factor in promoting retinal degeneration. These important data identify a new link between cells of the immune system and those within the retina which contribute to the progression of retinal degeneration.

      In this important work, the authors describe a recombinant CRISPR/Cas9 construct, CRISPR-nuPin, that has the reported capacity to rapidly tether DNA to the inner nuclear membrane of cells. They then evaluate the effect of this construct on Herpes Simplex virus type 1 infection, identifying different phases of viral replication susceptible to inner nuclear membrane tethering. This work provides convincing evidence for the effects of intranuclear DNA localization on viral gene expression and replication, using a method applicable to nonviral genes as well.

    1. eLife assessment:

      In this fundamental manuscript, the authors provide compelling evidence that a housekeeping ATPase is required for heme utilization in the important pathogen Staphylococcus aureus through its interaction with the canonical heme transporter in this organism. The authors convincingly show that this complex associates with functional membrane microdomains and thus establishes a new paradigm for regional localization of the heme transport system in the staphylococci. The work will be of interest to microbiologists, particularly those studying transport for macromolecules.

      This paper is of potential interest to scientists within the field of drug-induced liver injury. The concept of the study is interesting by generating mitochondrial genotype-specific liver cell lines to evaluate idiosyncratic hepatotoxicity. While the proof-of-concept is clearly presented, the current data do not yet allow to draw broad conclusions about the significance of the study in terms of drug effects.

      The precise cellular and molecular mechanisms and signaling mediators underpinning the development of cardiomyopathy and heart failure in diabetes still remains unclear. In-depth investigations of the cardiac heterogeneity and cell-to-cell interactions could be of use to reveal the pathogenesis of diabetic myocardial fibrosis and thereby identify potential targets for the treatment of cardiac myopathy and heart failure. Utilizing a mouse model as well as in-vitro studies, this manuscript demonstrates cardiac cell mapping that provides novel insights into novel drivers of intercellular communication contributing to pathological extracellular matrix remodeling during diabetic myocardial fibrosis. The work provides compelling and convincing evidence to improve the understanding the cellular and molecular mechanisms of diabetes-induced cardiac pathology.

      Leptin is a fat-derived hormone that curbs appetite, and mutation of leptin causes obesity and diabetes. This manuscript investigates leptin-responsive neural circuits, revealing a key inhibitory connection from leptin-sensitive neurons in the arcuate nucleus of the hypothalamus (AGRP neurons) to neurons in the dorsomedial hypothalamus. Toggling this inhibitory connection impacted leptin effects on feeding and metabolism. The study contains valuable data, including several interesting molecular genetic systems and the demonstration of GABA signaling in the DMH for the control of food intake, however, there is inadequate information about experimental design, including a lack of quantification and controls, and unjustified assumptions.

      This fundamental study by Rose and colleagues addresses key challenges in demographic inference in non-model systems with an innovative approach to model parameter calibration based on known historical events. Using this approach, they convincingly show that human specialization in Ae. aegypti mosquitoes likely evolved due to a past climate event around 5,000 years ago, and that recent rapid urbanization has continued to fuel its spread in West Africa in the past 20-40 years. This work will be of broad interest to population geneticists working on demographic inference, and to mosquito biologists working on the monitoring and control of this important vector species.

      The fundamental work represents an important contribution to our understanding of the diversity of photosynthetic mechanisms across the branches of phototrophic life, with the first high-resolution structure (2.9 Å) of a photosynthetic complex from a primitive green alga. This is a valuable resource for understanding function and evolution of light-harvesting antennas. The evidence is convincing in suggesting that the mechanism found here is distinct from the classical antenna state transitions seen in other organisms studied thus far.

      This important study of mouse genetic variation in atrial septum formation, a trait correlated with the patent foramen ovale (PFO) cardiac defect, provides convincing evidence for 37 quantitative trait loci (QTL) affecting this trait, combining genetic mapping with transcriptome analysis to zero in on relevant pathways and candidate genes within the QTL, and validating the role of one gene in tissue culture. The paper provides an important resource for hypothesis generation and future studies, which could lead to novel diagnostic or therapeutic approaches that target atrial septal defects in common congenital heart disease.

      In this study, neurons were recorded and combined across the parahippocampal area while rats performed a memory-guided spatial navigation task. Sophisticated analytical tools were used to provide convincing evidence that neuronal populations in these areas show behavior-related changes that might indicate the encoding of errors by the system. The valuable results suggest that rate remapping is a likely mechanism to support changes in representations that support memory-guided behavior in these regions, most interestingly in neurons that code head direction.

    1. eLife assessment

      This important paper advances our understanding of the role of lipid peroxidation in loss of muscle mass and force-generating capacity during aging and hind-limb suspension. The evidence is in general solid, drawing from experiments in vivo and cell culture using multiple types of manipulations of the formation of lipid peroxides although some weaknesses were identified. The results should be of interest to those who study the molecular basis for sarcopenia and disuse atrophy of skeletal muscle.

      In this manuscript, the authors investigate the role of histone deacetylases in the spatial epigenetic control of zygotic gene expression in early gastrulation. They discover HDAC1 binding is maternally-controlled and that inhibition of histone acetylation blocks gastrulation and disrupts cell lineage integrity, tied to both positive and negative regulatory effects on gene transcription in space and time. The study contributes to a growing body of evidence that highlights a central role of histone acetylation-deacetylation dynamics in epigenetic regulation of gene expression and cell fating in early tissue patterning of the embryo.

      When a neuron is born it correlates with where it targets in the neuropil and this has been best demonstrated in the olfactory lobe of Drosophila. This important study uses sophisticated genetics and advanced live imaging to provide a compelling description of how neuronal dendrites explore the targeting field, eliminate excessive branches, and assort into the correct region during development. In the process, it develops valuable tools. It brings us closer to a comprehensive understanding of how the birth order of a neuron translates to dendrite patterning within the Drosophila antennal lobe circuit

      Black et al., provide evidence that levels of Paternally Expressed Gene 10 (PEG10) protein are regulated by Ubqln2 and that proteolytic fragments from PEG10 cleavage induce changes in gene expression, in particular genes that encode proteins involved in axon biology. Based on these data and the finding of an increase in PEG10 levels and alterations of proteins regulated by PEG10 in the spinal cord of ALS patients, they propose that abnormal induction of PEG10-regulated genes is involved in ALS. However, the evidence for these claims and PEG10 involvement could be strengthened, and the rigor of the work could be enhanced in places.

    1. eLife assessment

      This important study provides a provocative potential challenge to explain sensitivity across the visual field by using cortical magnification factors. The evidence supporting this theoretical challenge is solid in general, although the inclusion of subject-specific measurements of cortical magnification factors would have strengthened the study. The work will be of interest to vision researchers of both basic and medical science.

      This valuable study by Pasquereau and Turner examined the activity neurons in the subthalamic nucleus (STN) while monkeys performed a task in which they had to withhold their response during a delay period whose length was defined by a specific cue. The results indicate that the activity of STN neurons was modulated by reward size and delay. The results are potentially important for understanding how STN regulates behavior such as self-control, but the reviewers thought that the study is incomplete as the analyses, at least in the presented forms, have some potential problems and some analyses require clarification.

      These authors provide compelling evidence that gestational intermittent hypoxia, a component of sleep apnea during pregnancy, increases inflammation in the spinal cords of male mice. Increased inflammation is robustly linked to deficits in respiratory plasticity both biochemically and via functional depletion assays. These data are important given the fact that male infants have worse outcomes in the NICU and are at higher risk of sudden infant death syndrome.

      Brodbeck et al. offer a timely and important contribution to how neural signals in response to continuous temporal modulations (as seen in speech and language processing) can be modelled effectively using temporal response functions. They offer a convincing new approach that includes a novel application of a boosting algorithm in addition to an accessible and didactically useful toolbox for analysis. With further comparison to existing toolboxes, or a more extensive comparison of boosting and ridge regression via simulation, this work will have a compelling impact on methods in speech and language neuroscience, as well as in cognitive neuroscience more broadly.

      This important study advances our understanding of host-derived lipid droplets' interaction with intracellular pathogens. The use of amoeba species Dictyostelium discoideum as a host for Legionella pneumophila infection is compelling and goes beyond the current state of the art, but the strength of evidence is incomplete, and the main claims are only partially supported by the data. With the experimental part strengthened, this paper would be of interest to cell biologists and microbiologists working on the interaction of microbes with host cells.

      This useful work describes the establishment and characterization of new cell lines derived from specific tissues of the fruit fly Drosophila. The evidence supporting the claims of the authors is solid, although the characterization of the cell lines is incomplete and the genomic findings are not presented in a user-friendly manner. These lines could be a useful resource that complements in vivo Drosophila genetics, improving biochemistry and facilitating high-throughput screening.

    1. eLife assessment

      This important study examines the association between SARS-CoV-2 infection and close contact among household members, measured using proximity sensors deployed after the first case was identified in the household. The authors provide solid evidence that transmission of SARS-CoV-2 within households is not dependent upon close contact, but the study suffers from a number of limitations that are fully acknowledged.

    1. eLife assessment

      Regulation of gene expression in many biological systems occurs either through a binary mode where gene expression is either on or off (digital regulation), or through an analog mode leading to a graded modulation of gene expression. In this manuscript, the authors report how these two regulatory modes are integrated into a one-way switch pattern to control the expression of the Arabidopsis floral repressor gene FLOWERING LOCUS C (FLC). They suggest that an analog regulation in the autonomous pathway precedes a digital regulation conferred by Polycomb silencing before cold exposure, and this temporal switch correlates with the strength of transcription at the FLC locus in different genetic backgrounds.

      This study combines different approaches to unravel the genetic basis of a pigmentation polymorphism in natural populations of a fascinating study system with well-studied ecology. The paper has the potential to be of general interest to biologists curious about the genetic basis of adaptive variation, which is especially relevant to evolutionary biologists and ecologists. The study reports substantial data and makes a strong case for the contribution of a duplication-derived gene acquiring a morph-specific function. Further information is required to implicate valkea in pigmentation morph formation and for diagnosing the duplicated segment as a supergene (associated with low recombination).

      This study presents valuable findings from a study of identical twin pairs discordant and concordant for smoking to assess whether smoking has a direct effect on DNA methylation. The results are a valuable contribution as the study confirms the reported association between smoking and epigenetic profile is indeed due to the direct effects of constituents of tobacco smoke. The study design and methods applied by the authors are solid and provide a starting point for larger studies with rigorous laboratory approaches, as well as for assessing clinical impact. The work will be of broad interest to addiction researchers, genetic epidemiologists, and environmental scientists.

      This study presents important results on the predicted impact of cancer screening disruptions in Australia during the COVID-19 pandemic based on consultation with public health stakeholders. The evidence presented is solid, as simulations were based on several previously validated breast, cervical, and bowel cancer screening decision models, though the scenarios were based on hypothetical disruptions that do not always match experienced disruptions. The work will be of interest to local policy-makers, public health specialists, and cancer epidemiologists.

    1. eLife assessment

      This is important work that addresses a long-standing (but rarely acknowledged) question: given that multi-peaked tuning curves optimize Fisher information, why do early sensory areas typically have single-peaked tuning curves? This paper shows clearly, and convincingly, that multi-peaked tuning curves are likely to produce catastrophic errors at short times, so if speed is important, multi-peaked tuning curves should be avoided. This work should encourage neuroscientists to take into account the importance of stimulus encoding time in their formulations of models of neural coding.

      Endothelial cells mediate the growth of the vascular system, but they also need to prevent vascular leakage, which involves interactions with neighboring endothelial cells through junctional protein complexes. This important study provides a full mechanistic insight into how Sun1 is achieving its function, which supports the concept that nuclear anchoring is critical for proper mechanosensing and junctional organization. Although the evidence supporting the claims of the authors is solid and there are several merits and strengths in this study, a weakness is that some important controls are missing. The work will be of broad interest to cell biologists and vascular biologists.

    1. eLife assessment

      This manuscript presents a useful meta-analysis of genes with parent-specific expression from mouse published RNA-seq datasets, focusing on genes with weak allelic bias. A combination of systematic bioinformatic analysis and experimental validation convincingly shows that the number of parentally biased genes has been overestimated and the few novel ones lie at the periphery of known imprinted loci. The work will be of interest to genomicists with an interest in imprinting and its mechanisms.

    1. eLife assessment

      This study will be of interest to scientists within the field of hematopoiesis and ribosome biology. The paper provides evidence that haploinsufficiency of the mouse ribosomal protein gene Rps12 results in a number of phenotypes including defects in the production of specific blood cells and loss of hematopoietic stem cell quiescence. This work adds to the growing body of evidence that specific cell populations are particularly sensitive to disruption of mRNA translation machinery.

      This manuscript describes an approach for efficiently integrating diverse libraries into the C. elegans genome. The method is a valuable contribution for researchers carrying out experiments that would benefit from easy generation of such libraries, and the data for the effectiveness of the method is solid. The relative advantages of this approach in terms of ease and effectiveness relative to others with similar aims will emerge as they are put to more general use in addressing biological problems.

    1. eLife assessment

      The study has some significance for the field of dementia research and neurodegenerative diseases more broadly. Using the brain-age paradigm, the main findings are that having an older-appearing brain is associated with more advanced stages of amyloid and tau pathology, higher white matter hyperintensities, higher plasma NfL and carrying the APOE 34 allele. Findings were broadly similar in cognitively normal people and people with mild cognitive impairment and the evidence for these findings is convincing. Although sex differences are emphasized, the evidence for this is generally incomplete.

    1. eLife assessment

    1. eLife assessment

      The authors present valuable findings regarding the mechanism of high mannose induced cellular toxicity in cancer cells. The evidence supporting genomic instability as the anti-cancer activity of mannose is convincing with multiple orthogonal approaches showing consistent results, but the conclusions related to metabolic remodeling could be further strengthened by additional metabolomics data. While the findings are limited to genetically modified cancer cell lines cultured in vitro, this work will be of interest to cell biologists working on cancer metabolism.

    1. eLife assessment

      This potentially important study examines brain age based on resting state functional connectivity (RSFC) following an 18-month lifestyle intervention. The design of the intervention study is generally solid; the randomized controlled trial includes three intervention groups and assessments at two-time points of numerous health markers, however, the methodology for brain age prediction appears somewhat incomplete and would benefit from more rigorous approaches. The lack of control groups also prevents firm conclusions about the extent to which the observed RSFC changes are linked to the intervention. With these parts strengthened, the paper would be of broad interest to neuroscientists and biologists working on obesity, lifestyle interventions, and brain health.

    1. eLife assessment

      This paper reports a valuable new method for creating localized damage to candidate brain regions for functional and behavioral studies. The authors present solid support for their ability to create long-term local lesions with mm spatial resolution, although data supporting the extension to primates was incomplete. If the authors can demonstrate that the technique is applicable beyond the specific technical setup they employ, the paper is likely to be of broad interest to brain researchers working to establish causal links between neural circuits and behavior.

    1. eLife assessment

      This useful work proposes a framework inspired by chemotaxis for understanding how the brain might implement behaviours related to navigating towards a goal.

      This important study presents the idea of "Skeletal Age", defined as the age of one's skeleton as a consequence of fragility fracture, as a potential new tool to raise awareness about the increased risk of mortality following a fracture (particularly hip fractures) and thus improve the medical management of osteoporosis. The evidence is convincing and is derived from a very large database from the Danish National Hospital Discharge Registry. The proposed approach might represent a starting point for making doctor-patient communication about the health risks of an osteoporotic fracture more intuitive and possibly more effective.

The evidence supporting the claims of the authors is solid, although antibody effectiveness as a prophylactic or therapeutic reagent in an animal model would have strengthened the study. The work will be of interest to biologists working to develop pan-coronavirus therapies.

    1. eLife assessment

      Germline inactivation of NPHP2, which encodes a protein that localizes to the transition zone at the base of the primary cilium, results in infantile kidney cysts and fibrosis. In this study, the authors provide solid evidence that increased cell proliferation and fibrosis precede cyst formation in Nphp-2 mouse models, that mutant renal epithelial cells are responsible for the phenotype, and that genetic inhibition of ciliogenesis in this model reduces disease severity. They also show that valproic acid, a drug that affects a number of cellular targets and is used to treat other human conditions, slows disease progression. One limitation of the study is that it provides limited insights into the mechanisms responsible for any of its interesting observations.

      This important study by Bonnet et al addresses the question of how AMPA receptor numbers at the synapse are regulated during basal conditions and during chemically induced Long Term Potentiation. Specifically, the study aims to determine the molecular mechanisms that contribute to the intracellular trafficking of AMPA receptors and determine their insertion into the synaptic plasma membrane. Using compelling methodology, the authors dissect the distinct roles of two proteins that bind to the C-terminal domain of the AMPA receptor subunit GluA1: 4.1N and SAP97. The findings will be of interest to anyone trying to understand molecular events contributing to synaptic plasticity in health and disease, and more broadly, the method could be adapted for tracking intracellular movements of a wide range of proteins.

      This paper is of interest for skeletal biologists studying bone marrow stem/progenitor cells and bone remodeling. Using Adipoq-Cre-driven conditional deletion of Csf1 that encodes M-CSF and reanalyzing publicly available scRNAseq data, the authors recognize a subpopulation of bone marrow cells (i.e. AdipoQ-lineage progenitors) as an important source of M-CSF. The authors found that M-CSF production from these bone marrow cells influences the development of macrophages and osteoclasts as well as bone mass, including the bone loss associated with estrogen deficiency. This is a clearly written and nicely presented study that has potential to offer important new information regarding the source of M-CSF in the bone marrow.

      This paper is of interest to immunologists conducting single-cell analyses of T-cell recognition. It provides a means of curating datasets to ensure T cell-antigen pairs are identified. The data generated through this method often suffers from a relatively high background, so the authors present a computational approach to enhance the signal-to-noise of this type of analysis. At this stage, it is unclear if the thresholds and filtering steps described by the authors can be generally applied to other datasets of different qualities than the one used here.

    1. eLife assessment

      This study presents a valuable mathematical model for the adaptive dynamics of cancer evolution in response to immune recognition. The mathematical analysis is rigorous and convincing, and overall the framework presented could be used in the future as a solid base for analytically tracking tumor evasion strategies. However additional discussion is needed to clarify certain gaps between the theory and cancer evolution in real systems. The work will be of interest to evolutionary cancer biologists and potentially it may also have implications for the design of clinical interventions.

      This study presents a valuable finding on the critical features and patterns of m1A modification and in neurons and OGD/R-treated neurons. Moreover, the authors identified m1A modifications on different RNAs and explored the possible effects of m1A modification on the functions of different RNAs via an integrated approach of omics and bioinformatics. The evidence supporting the claims of the authors is solid, although inclusion of more in-depth studies to analyze the transcription factors for the upstream regulation would have strengthened the study. The work will be of interest to neurobiologist and scientists in the field of RNAs.

      Scott et al use Drosophila as a model to study the sialylation pathway and its role in nervous system function. Surprisingly, they find that the critical substrate for sialylation, CMP-Neu5Ac, is 'outsourced' to glia. This significant study presents a new twist in mechanisms underlying protein glycosylation and uncovers a new layer in the complex interplay of neurons and glia.

      This work is an attempt to establish conditions that accurately and efficiently mimic a drought response in Arabidopsis grown on defined agar-solidified media – an admirable goal as a reliable experimental system is key to conducting successful low water potential experiments and would enable high-throughput genetic screening (and GWAS) to assess the impacts of environmental perturbations on various genetic backgrounds. The authors compare transcriptome patterns of plants subjected to water limitation imposed using different experimental systems. The work is valuable in that it lays out the challenges of such an endeavor and points out shortcomings of previous attempts. However, a lack of water relations measurements, incomplete experimental design, and a lack of critical evaluation of these methods in light of previous results render the proposed new methodology inadequate.

      This study links chromatin remodeling with antifungal drug resistance in Cryptococcus neoformans. The work is important because it reveals a new facet of how drug resistance can emerge and associates. The work presented is well done but the story is incomplete since there are questions about methods and association that need to be addressed. Establishing a link between chromatin remodeling and antifungal resistance is a finding that would be of interest to infectious disease researchers, cell biologists, and drug developers.

      There are many strengths in this paper that examines patterns of epididymal blood and lymphatic vasculature, supported by quantitative methods, and well-conducted 3D imaging studies (graphics and videos). Minor weaknesses include the lack of higher magnification images and the organization of image panels in some figures. Overall, this is a very important contribution to the epididymis research field.

    1. eLife assessment

      This study, of interest to population geneticists and evolutionary biologists alike, aims at investigating temporal variation in patterns of germline mutation during the evolution of human populations. The authors suggest that shifts in mutation spectra occur frequently, over a few thousands of generations, possibly as a consequence of changes in environmental exposure, or of genetic modifiers. There are several important aspects of methodology that need to be clarified, and several additional tests have to be done to confirm that the reported observations are not the result of methodological artifacts. The paper also overstates certain weaknesses of previously published papers on mutation spectrum evolution as well as the generation time hypothesis; correcting these oversimplifications would more accurately capture what the paper's new analyses add to the state of knowledge in these areas.

      This manuscript provides compelling evidence that macrophages transfer mitochondria to cancer cells and that transferred mitochondria stimulate proliferation in recipient cells. The usage an array of clever cell biology-based tools provides compelling evidence for these claims despite the difficulties associated with studying a relatively low probability event. Solid evidence supports the proposed model that transferred mitochondria induce proliferation by stimulating ERK signaling in a ROS dependent manner, although at present some aspects of the proposed model are incomplete. The work has broad significance for both mitochondrial biology and cancer biology as the authors show clear evidence of mitochondrial transfer in mouse models of human tumors.

      Opioid-induced respiratory depression is one of the side effects of opioid drugs. Although opioid overdose deaths are highly prevalent, our knowledge of the neural circuits underlying respiratory depression in the brainstem is far from complete. The present study used a variety of sophisticated experimental techniques to convincingly reveal the identity of brainstem components that are part of the neural circuits involved in the mediation of opioid respiratory effects, together with defining potential synaptic underlying mechanisms. They focused on two regions of the brainstem, namely the Kolliker-Fuse and the preBötzinger Complex, and proposed a combination of three complementary processes at pre- and post-synaptic sites in both KF and preBötC regions to explain respiratory depression linked to opioid exposure. This study provides very important findings on the circuitry involved in opioid-induced respiratory depression, and the present results are of broad interest to the respiratory control research community, as well as medically relevant.

      This is a valuable study showing that fast, but transient, modifications of the synaptic efficacies, alone, can support the integration of information over time. Convincing supportive evidence is provided by showing that feed-forward networks, when equipped with such short-term synaptic modulations, can successfully perform a variety of temporal integration tasks at a performance level comparable with that of recurrent networks. These results will be of interest to both neuroscientists and researchers in machine learning.

      Bone marrow stromal cells (BMSCs) can differentiate into a variety of cell types such as osteoblasts, chondrocytes, and adipocytes. The authors of this important study provide compelling and strong evidence that ablating O-GlcNAc transferase (OGT) in BMSCs impairs bone formation but promotes marrow adiposity. The results show that the balance of osteogenic and adipogenic differentiation of BMSCs is controlled by reciprocal O-GlcNAc regulation of lineage-specifying transcription factors, and highlights the importance of an intracellular glycosylation process of specific proteins in bone formation and bone marrow adipocytes.

      The analysis of 89,000 independent somatic mtDNA mutations provides compelling evidence that allows the authors to refute the idea that reactive oxygen species (ROS) are a main driver of mtDNA mutagenesis, although ROS effects may still be tissue-dependent. These are fundamental results with convincing evidence, and they should appeal to a broad audience. The discovery of transversion mutations (C>A/G>T and C>G/G>C), which previously were assumed to be almost nonexistent, will nevertheless require additional validation.

      This important study advances our understanding of the composition and circuit organization of the preBötzinger complex (preBötC)-the brainstem region that generates the respiratory rhythm and coordinates breathing with different motor and physiological behaviors in mammals. The reviewers agreed that the evidence supporting the conclusion that the preBötC is composed of a segregated subgroup of output neurons that modulates orofacial muscle activity is compelling and based on technically elegant, state-of-the-art combinatorial dual viral transgenic and optogenetic approaches in rats. After the cytoarchitectonic analyses are strengthened, the work will be of interest to neuroscientists and physiologists working on the neural control of breathing and other motor systems.

      This study on snapping shrimp morphological weaponry presents important findings on trade-offs in investment in costly weaponry traits as related to body size and reproduction. Convincing evidence is based on the collection of an exceptional number of fields samples, the inclusion of three shrimp species, and the measurement of numerous morphological and behavioral traits. The evidence shows that there are size-dependent trade-offs, where males and females differ in weapon investment, as weapons are beneficial to males but expensive for females. The findings will be of broad interest to evolutionary biologists and researchers working in the field of animal behavior.

      This important work presented is of interest to the electron microscopy community, which expanding to more and more cell biologists. The field has long searched for a suitable method to combine the pristine preservation of vitrified samples with a volumetric imaging modality that reveals subcellular architecture at sufficient contrast for ultrastructural analyses, and the authors describe here the use of novel ion beams for imaging cellular samples in three dimensions, concluding that one of the four plasma sources tested produces the highest quality images. This allows them to provide several recommendations for imaging along with software for improving collected images. This approach should be very useful for addressing many biological questions.

      A small proportion of the genomes of humans whose ancestors lived outside Africa traces back to an interbreeding event with Neanderthals. While we know that selection has generally acted to remove Neanderthal ancestry, intense interest has focused on understanding the contribution to current human phenotypic variation. This paper uses a new set of approaches to carefully quantify this contribution, taking into account various complicating factors. The work will be of interest to colleagues in human evolution and evolutionary biology more generally.

      This manuscript will be of interest to centrosome and cilia cell biologists. It evaluates the in vivo and in vitro role of PCM1, and by extension, centriole satellites in ciliogenesis. The major strength of this study is the detailed characterisation of Pcm1-/- mutant mice, which reveals a role for PCM1 in biogenesis of specific types of cilia, such as motile cilia on ependymal cells. The claims are generally well supported by the data, but the mechanistic basis for the cell-type specific requirement for PCM1 in ciliogenesis remains to be fully clarified.

      The RNA-binding protein Tristetraprolin (TPP) regulates the abundance of mRNAs encoding proinflammatory cytokines. The study by Scinicariello and collaborators examined mechanisms regulating the turnover of TTP in cultured cells and identified the ubiquitin E3 ligase HUWE1 as a regulator of TPP degradation. The conclusions are largely supported by the cellular and biochemical experiments. This paper thus implicates the HUWE1-TPP axis in regulating macrophage inflammatory responses at the post-transcriptional steps.

      During meiotic prophase I, protein complexes essential for crossover recombination are distributed non-randomly along chromosomes. With mathematical modelling and based on results from super-resolution microscopy, the authors introduce a second type of coarsening of protein ensembles between chromosome axes and nucleoplasm between chromosomes and nucleoplasm to support the random distribution of the complexes in the synapsis-defective mutant. The new model is interesting and may be applied to other chromosomal events accompanied by the formation of large protein ensembles on the chromosomes. The work is of interest to colleagues studying recombination and meiosis.

      This extraordinary study mapped the circuit architecture of a brain module for learning and memory in the octopus brain. In particular, one gyrus of the Octopus vulgaris brain vertical lobe was imaged with volume electron microscopy, its neurons reconstructed and their synapses mapped. The acquisition of this pioneering data set was followed by a very convincing analysis of the circuits supporting learning and memory, and therefore behavioral plasticity, in this animal. The data and findings establish an important point of comparison with analogous brain structures in other organisms, such as the vertebrate cerebellum and the arthropod mushroom body, offering a new neural circuit architecture to support the study of behavior and inspire the design of artificial neural networks.

      Overall, this manuscript provides fundamental advances to our understanding of the ancestry of insect gustatory and olfactory receptors, by identifying new members of these two related ion channel families in distant species. The approaches to compare protein structure are exceptional and use cutting-edge techniques, going beyond the commonly used approaches. The authors suggest that the family of odorant and gustatory receptors have a common origin and share structural homology in very distant organisms, although the possibility of convergent evolution still exists. This work will serve as a reference for scientists working on insect olfaction and for those working on molecular evolution.

      In this important article, the authors characterize ancient DNA from maize unearthed in archaeological contexts from Paredones and Huaca Prieta in the Chicama river valley of Peru, recovered by painstakingly controlled excavation. The genetic evidence is compelling, albeit from a small sample size, but the dating evidence, despite the excellent archaeological context, is inadequate. Since the age of the samples is so important for the inferences, the individual radiocarbon determinations should be subject to further scrutiny.

      This is a valuable initial study of cell type and spatially resolved gene expression in and around the locus coeruleus, the primary source of the neuromodulator norepinephrine in the human brain. The data are generated with cutting-edge techniques, and the work lays the foundation for future descriptive and experimental approaches to understand the contribution of the locus coeruleus to healthy brain function and disease. However, due to small sample size and the need for additional confirmatory data, the data only incompletely support the main conclusions presented here. With the strengthening of the analyses, this paper, and the associated web application, will be of great interest to neuroscientists working on arousal-based behaviors and neurological and neuropsychiatric phenotypes.

      Based on two room-temperature X-ray crystallographic screens of PTP1B phosphatase against two sets of chemical fragments, and by comparing the results from a previous cryo screen, the authors report the important observation that, in addition to overlapping but non-identical sets of hits compared to the cryo screen, the room-temperature screens lead to significant differences in terms of binding sites and poses for some of the hits. The study provides compelling support for the use of room-temperature X-ray crystallography in early-stage drug discovery and highlights that temperature should be used as a parameter in efforts to extract additional insight from such analyses.

      The authors have combined their two recently developed novel approaches to Mendelian randomization studies (1) Lifecourse mendelian randomization which relates genes to the outcome, eg obesity, at different stages of life, and (2) Tissue partitioned mendelian randomization to determine if there are different genetic effects in different tissues. They have successfully combined these two approaches to investigate the influence of adiposity on circulating leptin in childhood and adulthood to demonstrate the value/proof of concept of combining these two techniques. This is very clearly presented and well-conducted work showing both new methodology and compelling results and will be important to both those who use Mendelian randomization and those who are interested in obesity.
