This important study develops a new technical advancement in ex vivo live imaging of hematopoietic tissues to monitor blood cells in their native microenvironment. The new method for live imaging and tracking is compelling, and the strength and breadth of hematopoietic analysis are convincing. This work provides a very useful new system for immunologists and cell biologists, which will supply new perspectives on the system-level mechanisms of cell differentiation and innate immunity.

eLife assessment

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.

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.

eLife assessment

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.

eLife assessment

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.

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.

eLife assessment

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.

eLife assessment

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 work will be of interest to cell biologists and biochemists studying cell division and kinase regulation.

eLife assessment

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.

eLife assessment

This valuable study carried out a genetic screening of Drosophila lines expressing wild-type or ALS/FTD mutations of ubiquilin 2, and identified several suppressors and enhancers of ubiquilin 2 phenotypes. The study particularly focused on two genes involved in axon guidance pathways, unc5 and beat-1b. The evidence supporting the conclusions is solid, although some of the presented data are unrelated to the main findings, which detracts from the focus of the work. This work will be of interest to a broad audience studying ALS/FTD and neurodegenerative diseases.

eLife assessment

In this useful and potentially important manuscript, Mazanek and colleagues combine computational analysis and in vitro experiments to develop a comprehensive analysis of the ability of pyrin-only proteins (POPs) to inhibit inflammasome assembly.

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.

eLife assessment

This manuscript reports important and valuable new data about the intriguing role of the lncRNA Charme during cardiac development.

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.

eLife assessment

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.

eLife assessment

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 important bibliometric analysis shows that authors of scientific papers whose names suggest they are female or East Asian get quoted less often in news stories about their work. While caveats are inevitable in this type of study, the evidence for the authors' claims is convincing, with a rigorous, and importantly, reproducible analysis of over 20,000 articles from across 15 years. This paper should be of interest to all scientists and science journalists, as well as to those who study science communication.

eLife assessment

The manuscript provides valuable insights into the regulatory role and mechanisms of the spectrin cytoskeleton in mechanotransduction in Drosophila.

eLife assessment

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.

eLife assessment

This study provides evidence that the Stromalin Antigen (SA) proteins known to ubiquitously interact with cohesins, retain their capacity to bind CTCF and chromatin in the absence of RAD21 cohesin component. Authors imply that SA has an independent function in addition to its joint role with RAD21 and CTCF, providing experiments that make them suggest that SA proteins organize around RNA:DNA regions in the absence of cohesin, contributing to R-loop regulation and linking chromatin on structure to cohesin loading. The paper is a nice piece of work of interest to readers in the field of cohesin biology and genome organization. However, additional, experiments would be required to strengthen some of the conclusions.

eLife assessment

Signaling mediated by Semaphorins and their receptors Nrp1 and Nrp2 is crucial for regulating the morphology of dendritic spines and dendritic arborization during development. In this manuscript, the authors found that the post-translational modification of S-palmitoylation dictates the subcellular localization and trafficking of Nrp2, but not Nrp1, and is required for Sema3F-dependent pruning of spines on the apical dendrites of layer V cortical neurons. The study provides important insights into how semaphorin signaling achieves spatial specificity on diverse downstream cellular events.

This work will be of interest to cell and computational biologists working on learning/memory.

eLife assessment

This study advances the understanding of metabolic regulation underpinning self-renewal of stem cells. The authors report that glutamine-dependent acetylation of the kinase PASK regulates its nuclear localization. Evidence is provided that nuclear PASK binds and disrupts Wdr5 association with the anaphase-promoting complex/cyclosome and is a trigger for the activation of myogenic programs in cultured cells. The study will be of interest to an audience in the areas of stem cells, regeneration and metabolic signalling.

This study may be valuable in differentiation of primary naive B cells into ASC ex vivo and will be of interest for immunologists with emphasis in B cell biology.

eLife assessment

The authors state that there is scant experimental evidence of divisive normalization of neural responses in the human brain. They used fMRI BOLD response to high-level stimuli to explore normalization in V1, object-selective (LO and pFs) and category-selective regions (EBA and PPA) as well effects of attention on cortical responses. Specifically, the authors first test the degree to which BOLD responses to body parts and houses exhibit responses predicted by a non-linear normalization model, compared to two linear models (weighted sum and weighted average). They find that responses, when considering responses to one vs two stimuli, are best fit with the normalization model. They then suggest that object-based attention effects can be better accounted for by a normalization model of attention, compared to attention variants of the aforementioned models. The paper could potentially be an important contribution to the fields of perceptual and cognitive neuroscience, but the conclusions are not sufficiently supported by the data at this stage. Several theoretical and methodological concerns limit the conclusions of this study.

This study thoroughly characterizes the morphology of an interesting folded membrane structure that links the epidermis to the cuticle in C. elegans. This structure, here named the meiosome, has been noted by several previous researchers. The study would be strengthened by providing additional support to the notion that the VHA-5::GFP transgenic reporter, used by the authors, faithfully labels the meisosome, and by stronger evidence that meiosomes indeed serve as attachment platforms between the cuticle and the epidermis.

eLife assessment

This fundamental and timely study provides insights into the structural dynamics of several relevant mutant forms of SARS-CoV-2 spike protein, including the most recent omicron variant. The hydrogen/deuterium-exchange studies provide compelling evidence for the stabilization of the spike stalk in conjunction with increased dynamics of the N-terminal domain, where binding to the ACE2 receptor occurs. These results have profound implications for the development of small molecule inhibitors of the spike protein-ACE2 receptor interaction.

This finding has the potential to improve current therapeutic strategies based on cell therapy and may indicate new biology related to how mesenchymal stem cells affect the immune state within the tumor microenvironment. Further research is necessary to clarify the signaling pathways, but the data presented by the authors are generally well-supported and convincing.

This manuscript makes a valuable contribution to the field. The authors have developed a compelling network model to study mechanisms for the emergence of oscillations in the beta range in the primary motor cortex during movement preparation, and their propagation as traveling waves across the cortical sheet. The model is able to recapitulate several features of motor cortical activity acquired experimentally. Due to the recent results suggesting a functional role for traveling waves, it is of great interest to discover the mechanisms underlying such phenomena, and this work is an interesting step in that direction. However, the evidence for the reported new insights is incomplete at this stage, due to some weaknesses that remain to be addressed.

This paper will be of fundamental interest to many sub-disciplines of neuroscience, ranging from cognitive neuroscientists to cellular neuroscience. It provides compelling and substantial brain and behavioral evidence of a novel intervention that can boost long-term memory. The key claims of the manuscript are generally well supported by the data, though the correlational nature of the data in different types of experiments raises some issues about interpretation.

eLife assessment

The authors present interesting information regarding the possibility of targeting the oncogenic K-Ras(G13C) mutant with nucleotide competitors. The experiments represent a solid support of the claims and show that this approach can work despite concerns about the high affinity of GTP and its high cellular concentration. These results will be of high interest for all working in the Ras field and in targeting oncogenes with small molecules. A weakness of the manuscript is the lack of direct physiological insights.

eLife assessment

This manuscript will be of interest to a wide range of cell biologists interested in understanding cell-cell communication. The discovery that an engulfing cell can control the extrusion and degradation of large vehicles from its target cell is important and intriguing. The authors present compelling data that show that exophers (large neuronal extrusions proposed to discard toxic cargo) are taken up by adjacent hypodermal cells, split into smaller fragments, and eventually degraded by lysosome fusion. The authors identify a number of small GTPases and accessory components, as well as the phagocytic receptor (CED-1) and the likely eat-me signal (phosphatidylserine).

eLife assessment

The manuscript proposes a mechanism by which different S-adenosylmethionine (SAM) synthase enzymes exhibit specificity towards target sequences, thereby proposing a novel layer of control over H3K4 trimethylation (H3K4me3). Such specificity is demonstrated in the context of responses to heat stress for two Caenorhabditis elegans SAM synthase enzymes, supporting the existence and importance of this novel mechanism of epigenetic control.

eLife assessment

The authors document an in-depth analysis of introduction patterns of 5 variant waves in Mexico. This is an important analysis and dataset since the genomic epidemiology of SARS-CoV-2 in Mexico is generally understudied, and this paper contributes important missing information. The phylogenetic analyses are solid and well-presented, but the lack of detail regarding the collection of samples across Mexican states makes it difficult to evaluate conclusions about the relationship between observed viral lineages and local case counts. Additionally, in its current form, the manuscript is mostly descriptive, without clear hypotheses tested or discussion of implications.

This important work advances our understanding of the factors that affect the speed of colour evolution in birds and the resulting diversification patterns. It provides compelling evidence that more complex plumage coloration can lead to rapid colour evolution in kingfishers, and could pave the way for more comprehensive analyses that fully embrace the multidimensional nature of colour variation. Hence, the results will be of broad interest to ornithologists and evolutionary biologists in general, once the authors have streamlined the theoretical framework and explained the novel methodological approaches in more detail.

eLife assessment

This valuable manuscript describes a fully automated touchscreen cognitive testing system for rats that reduces the length of training required to learn a task and eliminates the need for daily handling. These features make it possible to assess cognitive behaviors in conjunction with other neurobehavioral paradigms during adolescence, an important advance in the field. The data convincingly show that cognitive flexibility does not promote susceptibility to severe weight loss in the activity-based anorexia (ABA) paradigm. However, support for the claim that cognitive deficits seen in rats that had been exposed ABA adequately capture an important clinical feature of the pathophysiology of anorexia nervosa is incompletely supported.

eLife assessment

This study provides fundamental insights into the relationship between single neuron activity in superficial layers of the cortex and electrical signals recorded at the cortical surface. Based on solid measurements, the results indicate a weak correlation between individual layer 2/3 neuron activity and multiunit activity recorded at the surface, whose interpretation could be reinforced. In particular, a strong contribution of layer 1 axons to surface signals is suggested but relies on incomplete evidence.

eLife assessment

This manuscript provides valuable insight into the molecular mechanism by which destabilized mitochondrial proteins 'clog' import channels and contribute to the pathologic mitochondrial and cellular dysfunction implicated in human disease. The evidence supporting this conclusion is solid, utilizing yeast, mammalian cell culture, and mouse models. However, additional characterization of import clogging in the mammalian model systems would strengthen this study. This work will be of broad interest to researchers in the fields of mitochondrial biology, protein quality control and proteostasis.

eLife assessment

This manuscript tests an important assumption about how sensory information is processed and used to guide motor choices. The widely held assumption is that sensory-motor circuits are capable of integrating evidence, but the validity and generality of this 'principle' have been recently questioned by studies suggesting that other computational operations may lead to similar psychophysical results, mimicking integration without actually performing it. This study makes a compelling case that the integration assumption was likely correct all along and that the model mimicry can be easily disambiguated by using appropriate sensory stimuli and task designs that permit rigorous analyses.

eLife assessment

This important study provides convincing evidence that locus coeruleus is activated during visuomotor mismatches. Gain of function optogenetic experiments complement this evidence and indicate that locus coeruleus could be involved in the learning process that enables visuomotor predictions. This study therefore sets the groundwork for the circuit dissection of predictive signals in the visual cortex. Loss-of-function experiments would strengthen the evidence of the involvement of locus coeruleus in prediction learning. These results will be of interest to systems neuroscientists.

eLife assessment

The paper provides a valuable, in-depth mathematical analysis of the coevolutionary dynamics resulting from a coupling of players' strategies and (collective) risk, as well as illustrative numerical simulations of the system's trajectories for different starting conditions. It is therefore a solid contribution to our understanding of how cooperation can be sustained when there is feedback between individual decisions and the global risk of disaster. This paper will be of interest to scientists working on mathematical biology/ecology, and more generally various aspects of human decision-making, the interplay between human decisions and the environment, and public goods provision.

eLife assessment

This study addressed a long-standing question in biology - the role of fever during infections. Using innovative research strategy, the authors provide compelling evidence for the positive impact of higher body temperature on both pathogen clearance and tissue repair. This study thus provides important advances in our understanding of host defense and its connection with physiology and behavior.

eLife assessment

This manuscript reports novel and important findings on the mechanisms of regulation of CRAC channels. Collectively, the work represents an important conceptual advancement, showing that stromal interaction molecule-1 is not necessary for Ca2+-dependent inactivation of the Orai1 channel and that Orai1 likely contains a Ca2+ sensor for autoregulatio. The experiments are carefully conducted, and the data is of high quality and support the major conclusions of the authors.

eLife assessment

This important paper advances the understanding, in the model plant Arabidopsis thaliana, of the molecular basis of the promotion of flowering in the spring by exposure to winter cold through a process known as vernalization. In Arabidopsis, there are two classes of long non-coding RNAs produced only when plants are in the cold, and this work provides compelling evidence that the cold-induced expression of one of these (COOLAIR) involves C-repeat binding factor proteins that bind to cognate binding elements in the COOLAIR promoter, but also that COOLAIR is not required for the vernalization-mediated promotion of flowering under standard laboratory conditions in which the vernalization response is measured.

eLife assessment

This study provides fundamental insight into the functional impact of CDK4 inhibition on cells in the tumor microenvironment, which is of high importance and interest to the field. The compelling conclusion that proliferative exhausted T cells are associated with response in HPV+ head and neck cancer is supported by the cohort of 14 patients with paired tumor and adjacent normal tissue and rigorous bioinformatic analysis of nearly 50,000 single CD3+ T cell transcriptomes. This work will be of interest to researchers across tumor types and in other immunological fields of study.

eLife assessment

In this work, the authors provide convincing evidence about the existence of two distinct osteoclast populations with specific expression profiles and properties and show that the probiotic yeast S. boulardii may be useful in managing inflammation-mediated bone loss, including estrogen deprivation-mediated osteoporosis. The reported study aims to bring the concept of heterogeneous osteoclasts into a proof-of-principle therapeutic application, which may mean that the use of probiotics might combat osteoporosis towards a better bone quality than current therapies. The molecular mechanism of how the probiotic yeast S. boulardii treatment acts via the receptors remains obscure since it might act via changes in the gut permeability or by components directly released by the fungus.

eLife assessment

This paper will be of considerable interest to researchers studying the psychological and neural basis of variation in prosocial behavior. The authors use a sophisticated combination of computational modeling and EEG to show that variation in generosity produced by changes in context (i.e., disadvantageous vs. advantageous inequality) and variation due to individual differences in concern for others both seem to occur early, during the perceptual or valuation stage of a choice, rather than later on during choice comparison. However, these two sources of variation also appear to operate through distinct mechanisms during this stage of processing, which spurs further questions about the drivers of human prosocial behavior.

eLife assessment

The authors examine the function of Tomosyn, in dense core vesicle fusion in neuronal cultures from mice expressing conditional alleles of tomosyn and tomosyn-2. The authors show here that while loss of tomosyns did not affect dense core vesicle exocytosis, it reduced the expression of several key dense core cargos, including BDNF. However, "rescue" experiments are needed to validate the specificity of the effects.

The study provides a recurrent network model of M1 for center-out reaches. The "neurons" in the model show uncorrelated tuning for movement direction during preparation and execution with dynamic transition between the two states. The continuous attractor model provides an interesting example of flexible switching between neural representations.

This study describes the use of a new and valuable tool, namely phage display of Plasmodium falciparum proteome-wide peptides, for profiling of antibody targets. The study, conducted using plasma from Ugandan children and adults, represents an important aspect of naturally acquired antibodies with seroreactive responses to the intra-and inter-protein repeat regions. The results are, however, so far incomplete, and confirmatory data that antibodies to inter-protein repeat motifs do cross-react are needed.

eLife assessment

This highly important paper uses a Bayesian linear regression approach in a clinical trial to establish that ivermectin does not increase the clearance rate of SARS-CoV-2 relative to no study drug. The strength of evidence is compelling. Particular strengths are that the paper is clearly written, a novel and important adaptive study design, and linear mixed modeling to account for participant heterogeneity. The work will be of interest to clinicians, statisticians, and public health departments.

eLife assessment

In this useful study, the authors utilize state-of-the-art computational methods complemented with some experimental validation to investigate the dynamics of flexible loops of the L1 Metallo-β-lactamase enzyme, resulting in a better understanding of the various conformational states useful for the rational design of superior β-lactamase inhibitors/antibiotics. The evidence supporting the claims is solid, and the work will be of interest to computational, experimental biologists, and drug designers working on antibiotic resistance.

This manuscript is of potential interest for a broad spectrum of researchers working on the nervous and muscular systems. By combining transcriptome and proteome analyses, the authors reveal the molecular makeup of the different compartments of the muscle spindle. The work is novel, makes important observations, and is well-executed and methodologically convincing to provide the field with new tools for dissecting the development and function of the muscle spindle.

In this manuscript, the authors devised a new, useful mRNA-imaging approach by combining MS2 and SunTag labeling systems. The authors showed that this new method can be used to image the activation of gene expression and endogenous mRNA dynamics in live C. elegans. While the application in C. elegans has great future potential, this study is incomplete because it lacks essential characterization of the new imaging method to demonstrate that it does not interfere with RNA expression.

Zhang et al. present convincing data describing a role for Polo-like kinase PLK-2 in restricting the activity of Chk2 kinase and coordinating synapsis of homologous chromosomes with the progression of meiotic prophase in C. elegans. By revealing PLK-2-dependent and -independent mechanisms of CHK-2 activity, this work provides a valuable understanding of the major regulators of meiotic progression.

Li and colleague report observations that constitute a potentially fundamental advance, pointing to a mechanism by which non-neural cells can influence sleep regulation by neurons, The authors provide evidence in Drosophila showing that ecdysone synthesised outside the brain regulates sleep via ecdysone receptors in cortex glia. It further suggests that steroid signalling in glia can act on sleep through lipid droplet mobilization.

In this manuscript, the authors provide mechanisms by which HLA-I polymorphism affects the capacity in the endo-lysosomal assembly of HLA-I molecules for constitutive expression and during cross-presentation. The findings may have implications for allotype-dependent variation in T cell responses to antigens localized in different subcellular compartments. However, additional biochemical and quantitative data is essential to bolster the central claims of the paper.

the word disability has been used for such a long time that it has its definition tied to sociopolitical beliefs, therefor when there was an attempt by the community to change its meaning to be more accurate many people still refuse to do so.

ableist and ableis is the way to identify the individuals who see themselves as superior because they are able bodied. theres not enough awareness to make the public asses what is ableist

basically this page talks about how in the previous definition of disability was based on medical terms whose purpose was to sell an idea to the public

eLife assessment

The study is important in that it investigates the effect of reading acquisition on neural responses experimentally, randomly assigning children to one of two training groups. The results provide solid evidence for learning-related changes in the (late) neural response to words, but it is not clear whether this reflects category-specific changes in visual cortex tuning. As such, the study may not yet provide a clear answer to the neuronal recycling debate within which it was framed. This paper is of potential interest to a broad audience of neuroscientists, as it addresses fundamental questions regarding the re-organization of functional cortical responses associated with learning to read.

This important paper provides detailed cellular and molecular characterization of the olivocochlear efferents that project to the inner ear. These specialized motoneurons are the only source of feedback from the brain to the ear and have been difficult to access. This study convincingly categorizes the efferents, using single nucleus RNA-sequencing and 3D reconstructions of individual fibers and their pre-synaptic contacts onto target neurons in the cochlea.

This study presents important findings on the regulation of the phosphate export cycle and identify the phosphatase Sit4 as a crucial player in regulation of the inner membrane potential of mitochondria. Whereas some of the data are convincing, the analyses will profit from deeper insights concerning metabolism alterations (carbon sources, amino acids). The major strength however is a new insight on how the cells use alternative ways for maintaining a critical mitochondrial inner membrane potential, and therefore this study is interesting to the broad audience with interests spanning from bioenergetics, metabolism and organellar and cell biology.

This interesting and important methodologic study presents exciting new data identifying approaches to evaluating the cell biology of lung disease. Namely, the ability to identify and track dynamic and coordinated activities of multiple composite cell types in response to experimental interventions. They have developed an interesting label-free approach that collects biologically-encoded autofluorescence of epithelial cells by 2-photon imaging of mouse tracheal explant culture over 2 days. This study has the potential to inform a variety of experimental conditions in lung injury and repair.

This study is of interest to epidemiologists and geneticists studying the association between telomere length and lung cancer risk. This work provides useful insight into risk factors for lung cancer. Overall, the results of this study are solid, as the genetic instrument used here is better powered and the battery of MR analysis makes this broad set of results convincing compared to previous work.

The study is a careful investigation of the physical properties of hagfish slime and the underlying cellular framework that enables this extraordinary evolutionary innovation. It is a careful and detailed measurement with clear images. However, there is a need for a better contextualizing of the findings as a broader biological question, including the evolution of functional novelty, the adaptive processes, and the links between genetic and phenotypic evolution. Furthermore, the conclusions on the evolutionary origins and underlying genetics of hagfish slime based on comparative transcriptomic data need to be better supported.

The manuscript aims to provide a comprehensive insight into the development of the tuberal hypothalamus of the chick embryo. It thus presents a useful tool for scientists working in this particular subfield. However, the manuscript is incomplete as it is impossible for the reader to follow the conclusions made by the authors because the presentation of the data is not streamlined and the text is difficult to follow, even for experts.
