In this important contribution, Yan and colleagues describe a powerful and compelling strategy to generate concatamers of the BK channel and their fusion constructs with the auxiliary gamma subunits, which allows exploring contributions of individual subunits of the tetrameric channel to its gating and the study of heteromeric channel complexes of defined composition. Distinct examples are presented, which illustrate great diversity in the stoichiometric control of BK channel gating, depending on the site and nature of molecular perturbations. The molecular approaches could be extended to other membrane proteins whose N and C termini face opposite sides of the membrane.

This fundamental study presents experimental evidence on how geomagnetic and visual cues are integrated in a nocturnally migrating insect. The evidence supporting the conclusions is compelling. The work will be of broad interest to researchers studying animal migration and navigation.

eLife Assessment

Laaker et al. make an important finding that the cribriform plate acts as a unique neuroimmune interface that shapes local myeloid cell states during EAE-induced neuroinflammation. Using immuohistochemistry, flow cytometry, and single-cell RNAseq of doublets to interrogate cell-cell interactions, the authors provide solid evidence that macrophages, migratory dendritic cells (DCs), and fibroblasts interact at the site of CSF outflow, with DCs showing characteristics of immune tolerance. While the functional consequences of these cell states remain to be established, the work shows that the cribiform plate can play a key role in influencing immune cell composition and interactions with stromal cells.

eLife Assessment

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

eLife Assessment

This study presents a high-quality cryo-EM structure of the human kinase PINK1 in complex with the HSP90-CDC37 chaperone complex, capturing a partially folded intermediate in which the C-lobe and C-terminal extension are structured while the N-lobe remains unfolded and engaged by the HSP90 clamp. The structural data are broadly consistent with a recently published structure of the same complex, providing useful insight into early steps of PINK1 maturation and highlighting residues linked to familial Parkinson's disease. However, the mechanistic conclusions remain incomplete because the manuscript does not experimentally validate key hypotheses raised by the structure, including the functional roles of the C-lobe interface, the HPNI motif, the C-terminal extension, or the proposed competition between HSP90 and TOM20.

eLife Assessment

This valuable study demonstrates molecular changes associated with age related impairment in oligodendrocyte differentiation and ability to myelinate. The identification of particular genes that are associated with this decline will provide potential future targets for therapeutic interventions. The reviewers felt that the quality of the evidence was solid while identifying some minor weaknesses that if addressed would enhance the rigor of the study.

eLife Assessment

This useful study develops an individual-based model to investigate the evolution of division of labor in vertebrates, comparing the contributions of group augmentation and kin selection. The findings are solid in showing that, within the specific structure of the model and the parameter space explored, group augmentation can robustly favor the evolution of differentiated helper roles, particularly when age-dependent task switching and dominance dynamics are allowed to evolve. However, the evidence only partially supports the authors' broader claim that group augmentation is the primary driver of vertebrate division of labor. Several modelling assumptions, including the limited scope for synergistic task benefits, the restriction of helper effects to group-size-mediated benefits, and the relatively narrow exploration of cost and benefit parameters, constrain the potential for kin selection to generate division of labor and limit the generality of the conclusions.

eLife Assessment

This manuscript provides valuable novel insights into the role of interpersonal guilt in social decision-making by showing that responsibility for a partner's bad lottery outcomes influences happiness. Through the integration of neuroimaging and computational modelling methods, and by combining findings from two studies, the authors provide solid support for their claims. The findings will be of interest to researchers in the field of social neuroscience and decision making.

eLife Assessment

This study investigates how RNA molecules modulate phase separation, aggregation, and cytotoxicity of the staphylococcal virulent peptide PSMα3 and the human host‑defence peptide LL‑37 using an array of biophysical and cell‑based assays. If validated, these findings would be important, as they suggest that nucleic acids can tune the material state and bioactivity of amyloids, with implications for host-pathogen interactions and for the design of therapeutics that target phase behaviour. However, the evidence is incomplete: many key claims rest on qualitative imaging and contested assumptions about "functional" amyloids, and the absence of quantitative binding data, phase diagrams, and appropriate controls limits confidence in the conclusions.

eLife Assessment

In this valuable study, the authors present traces of bone modification on ~1.8 million-year-old proboscidean remains from Tanzania, which they infer to be the earliest evidence for stone-tool-assisted megafaunal consumption by hominins. Challenging published claims, the authors argue that persistent megafaunal exploitation roughly coincided with the earliest Acheulean tools. Notwithstanding the rich descriptive and spatial data, the behavioral inferences about hominin agency rely on traces (such as bone fracture patterns and spatial overlap) that are not unequivocal; the evidence presented to support the inferences thus remains incomplete. Given the implications of the timing and extent of hominin consumption of nutritious and energy-dense food resources, as well as of bone toolmaking, the findings of this study will be of interest to paleoanthropologists and other evolutionary biologists.

eLife Assessment

Mitochondrial DNA (mtDNA) exhibits a degree of resistance to mutagenesis under genotoxic stress, and this study on the mitochondrial Transcription Factor A (TFAM) presents important data concerning the possible mechanisms involved. The presented data are solid, technically rigorous, and consistent with established literature findings. The experiments are well-executed, providing convincing evidence on the change of TFAM-DNA interactions following UVC irradiation.

eLife Assessment

This valuable study provides convincing evidence that MgdE, a conserved mycobacterial nucleomodulin, downregulates inflammatory gene transcription by interacting with the histone methyltransferase COMPASS complex and altering histone H3 lysine methylation. This work will interest microbiologists as well as cell and cancer biologists.

eLife Assessment

In their valuable study, Beaudet, Berger and Hendricks provide a mechanistic link between disease-associated tau hyperphosphorylation, loss of cooperative tau envelope formation on microtubules, and dysregulation of axonal transport prior to aggregation. Using complementary in vitro reconstitution and human iPSC-derived neuronal assays with phosphodeficient and phosphomimetic tau constructs targeting 14 disease-relevant sites, the authors convincingly show that phosphorylation state alters tau organization on microtubules and differentially impacts kinesin- and lysosome-based transport. The evidence is solid and well aligned with the conclusions, yet the work could be further strengthened by incorporating additional controls and motor-specific assays to refine the mechanistic depth.

eLife Assessment

This study is a valuable contribution that comprehensively identifies and characterizes LC3B-binding peptides through a bacterial cell-surface display screen covering approximately 500,000 human peptides. The data presented are solid, although this approach has limitations (e.g., it cannot assess the effects of post-translational modifications, which are often relevant to LIR-mediated interactions). Validation of the newly identified binding peptides by demonstrating their interactions with full-length proteins in cells would further strengthen this manuscript.

eLife Assessment

The work convincingly demonstrates the role of the mycobacterial secreted effector protein MmpE, which translocates to the host nucleus and exhibits phosphatase activity. The study is particularly valuable in showing that both the nuclear localization signal sequences and residues critical for phosphatase function are essential for host gene regulation, lysosomal biogenesis, and intracellular survival. Future studies will be needed to explore additional host pathways modulated by MmpE, particularly in the context of infection with a fully virulent Mycobacterium tuberculosis strain.

eLife Assessment

The authors provide a useful resource and approach to identify early-stage biomarkers of MASLD progression, notably when no other apparent symptoms have arisen. The strength of evidence to support new MASLD signatures is solid as the work combines metabolomic and transcriptomic measures in blood and liver biopsies.

eLife Assessment

Kambali et al use optogenetic manipulations to examine whether the ventral hippocampal Schaffer collateral (vCA3-to-vCA1) and temporoammonic (EC-to-vCA1) pathways regulate anxiety- and fear-related behaviors in mice. They find that both pathways regulate the expression of fear (freezing) responses to a context and auditory conditioned stimulus paired with foot shock (trace conditioning protocol), but only the Schaffer collateral pathway regulates the expression of anxiety-related behaviors in the elevated plus maze, open field test, and Vogel conflict test. Overall, the study is valuable: it detects bidirectional effects of optogenetic excitation and inhibition in both pathways. However, the strength of the evidence in support of its main claims is incomplete.

eLife Assessment

This study provides valuable insights into the regulation of myogenic differentiation by identifying Leiomodin 1 as a modulator of proteome dynamics during myogenic differentiation. The combination of quantitative proteomics with functional perturbation experiments offers solid evidence supporting the idea that SIRT1 influences perturbations of myogenic differentiation upon LMOD1 inactivation. These findings advance our understanding of muscle differentiation and will be of interest to researchers studying muscle development and related pathologies

eLife Assessment

This elegant study presents a valuable approach to probing the structural features of the full-length human Hv1 channel as a purified protein, supported by rigorous biochemical assays and spectral FRET analysis, which will interest biophysicists and physiologists studying Hv1 and other ion channels. Overall, the work introduces an interesting labeling strategy and provides methodological observations that are of value in investigating hHV1. However, the analysis appears incomplete, requiring additional structural interpretation and mechanistic insight.

eLife Assessment

This study addresses a fundamental question in glycobiology by elucidating how a single-site processive enzyme orchestrates the alternating addition of sugars to synthesize complex polysaccharides such as hyaluronan. The findings are compelling, providing a clear mechanistic framework supported by strong experimental validation. Major strengths include the integration of high-resolution structural data with rigorous biochemical analyses, resulting in a well-supported model of hyaluronan assembly.

eLife Assessment

This important study introduces an approach to discovering antibiotic resistance determinants by leveraging diverse susceptibility profiles among related mycobacterial species, with particular relevance to high-level resistance against natural product-derived antibiotics. The research provides convincing evidence for the role of ADP-ribosylation enzymes in rifamycin resistance among mycobacteria, whilst also demonstrating that antibiotic susceptibility is not correlated with growth rate or intracellular compound concentration. The revision is substantively improved, but some broader claims still require additional experimental support. This work lays a significant foundation for understanding the complexity of antibiotic resistance mechanisms in mycobacteria and opens new avenues for future antimicrobial research.

eLife Assessment

This valuable study used genetic and pharmacological manipulations of insulin/IGF signaling in renal glomerular podocytes to address the role of insulin/IGF axis in podocytes. Solid data are presented to demonstrate that co-inhibition of insulin/IGF signaling in podocytes led to aberrant splicing of mRNAs, which could contribute to the loss of podocytes in vitro and in vivo in mice. As it stands, the study lacks the assessment of developmental phenotype of podocytes in the mouse model.

[Editors' note: this paper was reviewed by Review Commons.]

eLife Assessment

In this valuable study, through carefully executed and rigorously controlled experiments, the authors challenged a previously reported role of the Death Receptor 6 (DR6/Tnfrsf21) in Wallerian degeneration (WD). Using two DR6 knockout mouse lines and multiple WD assays, both in vitro and in vivo, the authors provided convincing evidence that loss of DR6 in mice does not protect peripheral axons from WD after injury, at least in the specific contexts of the mice and analyses performed in this study. Due to the lack of certain specific parameters from previous studies (sex, age, mouse strains etc.), the exact reasons underlying the observed inconsistencies between current and previous reports on the protective effects of DR6 remains to be determined. Overall, this is a carefully executed study providing invaluable information toward understanding DR6's role (or lack thereof) in axon degeneration.

eLife Assessment

This fundamental work significantly advances our understanding of how contact-dependent antagonism enables keystone bacteria to establish and maintain their niche over time. The evidence obtained is convincing, supporting most of the conclusions drawn. This work will be of significant interest to the microbiome research community.

eLife Assessment

This study reports an important and novel finding that TENT5A, an enzyme involved in fine-tuning poly(A) tail length on selected mRNAs, is required for proper enamel mineralization in mice. The evidence supporting the authors' conclusion that reduced expression of enamel matrix proteins (EMPs) in TENT5A-deficient mice results from shortened poly(A) tails remains incomplete, as TENT5A may possess additional functions independent of post-transcriptional regulation that are not addressed in the current study.

eLife Assessment

This important study characterizes a cascade of neural processes triggered by memory-based prediction errors. The study uses an impressive collection of approaches and methods to characterize and measure cognitive control, arousal, and memory changes as a function of memory-based violations. The analyses are technically sophisticated and rigorous and, taken together, provide solid evidence that there are multiple processes accompanying prediction errors, and that they differentially relate to successful encoding. The manuscript would be much improved by the addition of a discussion or visual schematic that integrates the numerous findings together into a more coherent model.

eLife Assessment

This computational study constitutes an extension to prior work on biophysical calcium-based synaptic plasticity rules with metaplasticity, investigating how single neurons can learn to perform non-linear pattern classification. This important work presents a significantly simpler solution to the studied problem with potentially broad applicability, there is however incomplete evidence to support the core conclusions.

eLife Assessment

Based on the perceived low efficacy of current therapies targeted to FGFR2 in gastric cancer (GC), the authors investigate an approach which combines SHP2 inhibition with existing FGFR2 inhibitors. The data were largely collected and analysed using solid and validated methodology. There is some useful data regarding combination therapy in a new clinical cohort, which supports previous studies that have reported the potential of targeting RTKs together with phosphatases.

eLife Assessment

This study investigates the folding and unfolding behavior of the doubly knotted protein TrmD-Tm1570, providing insight into the molecular mechanisms underlying protein knotting. The findings reveal multiple unfolding pathways and suggest that the formation of double knots may require chaperone assistance, offering valuable insights into topologically complex proteins. The evidence is convincing, supported by consistent agreement between simulation and experiment, though some aspects of the presentation and experimental scope could be clarified or expanded.

eLife Assessment

This important study provides a comprehensive comparison of the mechanisms through which different inhibitors affect the SARS-CoV-2 main protease, a pivotal antiviral drug target, and suggests a potentially broad-spectrum strategy to inhibit this critical viral enzyme by disrupting its dimerization states. However, whereas the biophysical analyses of the dimer stability are convincing, evidence supporting this new mode of mechanism to inhibit the main protease is incomplete and would benefit from a correlation of the biophysical observations with functional activity. With the functional validation part strengthened, this work would be of interest to biochemists and virologists working on anti-coronavirus drug discovery.

eLife Assessment

This work presents a brain-wide atlas of vasopressin (Avp) and vasopressin receptor 1A (Avpr1a) mRNA expression in mouse brains using high-resolution RNAscope in situ hybridization. The single-transcript approach provides precise localization and identifies additional brain regions expressing Avpr1a, creating a valuable resource for the field. The revised manuscript is clearer and more impactful, with improved figures, stronger data organization, and enhanced scholarship through added context and citations. Overall, the evidence is compelling, and the atlas should be broadly of use to researchers studying vasopressin signaling and related neural circuits.

eLife Assessment

Recent studies have shown that mRNA can be acetylated (ac4c), altering mRNA stability and translation efficiency; however, the role of mRNA acetylation in the brain remains unexplored. In this important study, the authors demonstrate that ac4c occurs in synaptically localised mRNAs, mediated by NAT10. Conditional reduction of NAT10 protein levels led to decreases in ac4c of mRNAs and deficits in synaptic plasticity and memory. These solid results suggest that mRNA acetylation may play a role in memory consolidation.

eLife Assessment

This valuable study examines the role of E2 ubiquitin enzyme, Uev1a in tissue resistance to oncogenic RasV12 in Drosophila melanogaster polyploid germline cells and human cancer cell lines. The solid evidence suggests that Uev1a works with the E3 ligase APC/C to degrade Cyclin A. This work would be of interest to researchers in germline biology and cancer.

eLife Assessment

This study presents valuable findings on the role of KLF6 in in vitro endothelial cells exposed to altered (high or low) shear stress with a customized microfluidic device to investigate mechanisms of atherosclerosis. The finding that altered shear stress results in endothelial cell ferroptosis through reduced expression of KLF6 is compelling and adds a new layer of complexity to the pathogenesis of atherosclerotic plaques. However, more detailed characterization of ferroptosis is needed.

eLife Assessment

Using genome databases, the authors performed solid bioinformatic analyses to trace the genomic history of the clinically relevant Staphylococcus aureus tetracycline resistance plasmid pT181 over the last seven decades. They discovered that this element has transitioned from a multicopy plasmid to a chromosomally integrated element, and the work represents a valuable demonstration of the use of publicly available data to investigate plasmid biology and inform clinical epidemiology. This work will appeal to researchers interested in staphylococcal evolution and plasmid biology.

eLife Assessment

This valuable study describes significant differences in prey capture behavior between PSD-95 knock-out and wild-type mice, despite prior work by the same authors showing only modest visual deficits in the former. The data convincingly demonstrated prey capture performance in PSD-95 knock-out mice to improve under monocular viewing conditions. However, this finding alone was inadequate to support the interpretation of results as revealing a deficit in binocular visual integration, especially given the lack of eye and head tracking data or consideration of alternative explanations for the observed behavior.

eLife Assessment

In this valuable study, the authors present traces of bone modification on ~1.8 million-year-old proboscidean remains from Tanzania, which they infer to be the earliest evidence for stone-tool-assisted megafaunal consumption by hominins. Challenging published claims, the authors argue that persistent megafaunal exploitation roughly coincided with the earliest Acheulean tools. Notwithstanding the rich descriptive and spatial data, the behavioral inferences about hominin agency rely on traces (such as bone fracture patterns and spatial overlap) that are not unequivocal; the evidence presented to support the inferences thus remains incomplete. Given the implications of the timing and extent of hominin consumption of nutritious and energy-dense food resources, as well as of bone toolmaking, the findings of this study will be of interest to paleoanthropologists and other evolutionary biologists.

eLife Assessment

This is an important study that identifies the developmental time window during which re-expression of TCF4 mutated in Pitt-Hopkins syndrome, can rescue phenotypic features of brain function in a TCF4 knockout mouse. The study presents compelling data using a viral transgenic intersection approach to show that TCF4 expression is required early in perinatal life. These findings have implications for the timing of possible gene therapy in people with Pitt-Hopkins-associated TCF4 mutations.

eLife Assessment

This study proposes a cross-species transcriptomic framework to predict vaccine reactogenicity, with implications for preclinical vaccine safety assessment. The findings show that mouse muscle transcriptomic signatures capture conserved inflammatory programs and can identify highly reactogenic formulations, with supportive but limited evidence for finer discrimination among licensed human vaccines. Overall, the work establishes a valuable foundation for translational biomarkers of reactogenicity, although the strength of evidence for broad cross-species predictive performance remains incomplete and would benefit from further validation.

eLife Assessment

The study presents a valuable finding on the ubiquitin-dependent regulatory loop in which proapoptotic Bim is targeted to the E3 ubiquitin ligase Cul5-Wsb2-mediated degradation through its sequestration by BCL2 proteins. The conclusions are supported by incomplete evidence and would benefit from additional experiments addressing both the mechanistic understanding and the physiological/cancer-related significance of the study.

eLife Assessment

This important work substantially advances our understanding of the role of synaptotagmin-7 (Syt7) in short-term plasticity at cortical glutamatergic synapses. The evidence supporting the conclusions is convincing, with rigorous and elegant quantal-level iGluSnFR imaging and failure-based analyses at single boutons. The work will be of broad interest to synaptic physiologists and molecular biologists.

eLife Assessment

This study presents useful findings on the molecular mechanisms driving female-to-male sex reversal in the ricefield eel (Monopterus albus) during aging, which would be of interest to biologists studying sex determination. The manuscript describes an interesting mechanism potentially underlying sex differentiation in M. albus. However, the current data are incomplete and would benefit from more rigorous experimental approaches.

eLife Assessment

This manuscript details important findings that DNA polymerase kappa shows age-related changes in subcellular localization within different cell types in the brains of mice, from the nucleus in young cells to the cytoplasm in old cells. The authors' findings suggest that age-related alterations in POLK localization could drive mechanistic and functional changes in the aging brain. The authors provide solid evidence for their study, with data broadly supporting their claims with minor weaknesses.

eLife Assessment

This structural biology study provides insights into the assembly of the GID/CTLH E3 ligase complex. The multi-subunit complex forms unique, ring shaped assemblies and the findings presented here describe a "specificity code" regulates formation of subunit interfaces. The data supporting the conclusions are convincing, both in thoroughness and rigor. This study will be valuable to biochemists, structural biologists, and could lay foundation for novel designed protein assemblies.

eLife Assessment

This important study provides mechanistic evidence that tea-adapted two-spotted spider mite overcomes green tea catechin defenses via the horizontally transferred dioxygenase TkDOG15, supporting a two-step adaptation model, combining enzyme refinement and inducible upregulation. The evidence is convincing because multi-omics signals converge with functional validation (RNAi knockdown and recombinant enzyme assays) and well-controlled behavioral/toxicity assays to link TkDOG15 activity and expression to survival and feeding on tea.

eLife Assessment

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

eLife Assessment

Li et al. present an important and innovative study linking developmental changes in sleep to ecological context in Drosophila mojavensis, and propose that sleep at one stage of an animal's life might anticipate needs at a future stage. The results fit well with this model, but are correlative in nature. The work is convincing, scientifically rigorous, and effectively bridges sleep biology and evolutionary ecology, opening promising new directions for the field.

eLife Assessment

This work presents a brain-wide atlas of vasopressin (Avp) and vasopressin receptor 1A (Avpr1a) mRNA expression in mouse brains using high-resolution RNAscope in situ hybridization. The single-transcript approach provides precise localization and identifies additional brain regions expressing Avpr1a, creating a valuable resource for the field. The revised manuscript is clearer and more impactful, with improved figures, stronger data organization, and enhanced scholarship through added context and citations. Overall, the evidence is compelling, and the atlas should be broadly of use to researchers studying vasopressin signaling and related neural circuits.

eLife Assessment

This study provides useful insights regarding the alterations of sleep architecture in a knock-in mouse model of Alzheimer's Disease (AD). These include age-related hyperactivity that is typically associated with increased arousal, a normal homeostatic response to sleep loss, and a stronger AD-like phenotype in females. Although the analyses are robust, evidence for the proposed mechanisms underlying abnormal sleep architecture is incomplete. Overall, the study may have a focused impact on the sleep and AD fields.

eLife Assessment

This important work employed a recent functional muscle network analysis to evaluate rehabilitation outcomes in post-stroke patients. While the research direction is relevant and suggests the need for further investigation, the strength of evidence supporting the claims is incomplete. Muscle interactions can serve as biomarkers, but improvements in function are not directly demonstrated, and the method's robustness is not benchmarked against existing approaches.

eLife Assessment

This important work introduces a splitGFP-based labeling tool with an analysis pipeline for the synaptic scaffold protein bruchpilot, with tests in the adult Drosophila mushroom bodies, a learning center in the Drosophila brain. The evidence supporting the conclusions is convincing.

eLife Assessment

This useful study uses creative scalp EEG decoding methods to attempt to demonstrate that two forms of learned associations in a Stroop task are dissociable, despite sharing similar temporal dynamics. However, the evidence supporting the conclusions is incomplete due to concerns with the experimental design and methodology. This paper would be of interest to researchers studying cognitive control and adaptive behavior, if the concerns raised in the reviews can be addressed satisfactorily.

eLife Assessment

Stearns and Poletti present a technically impressive study that aims to uncover a deeper understanding of microsaccade function: their role in perceptual modulation and the associated temporal dynamics. The question is useful, and advances prior work by adding temporal granularity. However, the strength of the evidence is currently incomplete. Additional analysis is needed to control for the effects of endogenous attention and to demonstrate changes in perceptual performance.

eLife Assessment

This important study identifies a novel role for Hes5+ astrocytes in modulating the activity of descending pain-inhibitory noradrenergic neurons from the locus coeruleus during stress-induced pain facilitation. The role of glia in modulating neurological circuits including pain is poorly understood, and in that light, the role of Hes5+ astrocytes in this circuit is a key finding with broader potential impacts. This work is supported by convincing evidence, albeit somewhat limited by the indirect nature of the evidence linking adenosine to nearby neuronal modulation, and possible questions on the population specificity of the transgenic approach.

eLife Assessment

This important study provides evidence for dynamic coupling between translation initiation and elongation that can help maintain low ribosome density and translational homeostasis. The authors combine single-molecule imaging with a new approach to analyze mRNA translation kinetics using Bayesian modeling. This work is overall solid and will be of interest to those studying translational regulation.

eLife Assessment

This manuscript reports important findings indicating that cell cycle progression and cytokinesis both contribute to the transition from early to late neural stem cell fates. Loss-of-function experimental evidence convincingly shows that disrupting the cell cycle or cytokinesis can alter cell fate. This work sets the stage for future investigations into the underlying mechanisms linking the cell cycle to the expression of temporal factors controlling cell fate.

eLife Assessment

This valuable study investigates the computational role of top-down feedback - a property found in biological circuits - in artificial neural network (ANN) models of the neocortex. Using hierarchical recurrent ANNs in an audiovisual integration task, the authors show that an anatomically inspired feedback motif induces a stable visual bias consistent with human perception and yields modest but meaningful benefits for learning dynamics and robustness. The strength of evidence is solid: the modeling, analyses, and controls mostly support the central claim that top-down feedback motifs impose persistent inductive biases that shape functional specialization and behavior. But the evidence for a broad, general framework that predicts behavior remains only partially supported, and the Methods would benefit from a compact, reproducible summary of hyperparameters and architectural details.

eLife Assessment

This study investigates the temporal dynamics of neural activity preceding self-initiated movements and makes a valuable contribution to this field. The authors identify key methodological and analytical limitations in previous work and introduce a novel approach to overcome the shortcomings in assessing how predictive neural activity is of an upcoming event. Applying generally solid methods and analyses, they show that a late-stage neural event, ~100 ms before movement execution, is most predictive of upcoming movements, whereas earlier neural activity is less informative. Although interesting, additional analyses are needed to strengthen confidence in this central claim.

eLife Assessment

This fundamental study reports the effects of the psychedelic drug psilocin on iPSC-derived human cortical neurons, analyzing different aspects of structural and functional neuronal plasticity. The evidence is convincing and supports the value of using iPSC-derived human cortical neurons for testing the potentially translational effects of psilocin and other psychedelic-related compounds.

eLife Assessment

This study provides valuable insight into stress biology by showing that yeast populations can rapidly evolve a trehalose producing resting state that substantially improves survival and rapid regrowth after freeze-thaw. This finding is consistent with the role of trehalose metabolism as a biophysical adaptation that is broadly relevant to the community working on environmental resilience and dormancy. The evidence is convincing: the authors integrate experimental evolution, cell-level biophysical measurements, and modelling in a mutually reinforcing manner.

eLife Assessment

The authors present an important set of data implicating ETFDH as an epigenetically suppressed gene in cancer with tumor suppressive functions. The evidence is convincing, with the authors demonstrating that suppression of ETFDH activity results in accumulation of amino acids that impact metabolism via hyperactive mTORC1.

eLife Assessment

This manuscript investigates the extremely interesting and important claim that the human hippocampus represents interactions with multiple social interaction partners on two relatively abstract social dimensions - and that this ability correlates with the social network size of the participant. This research potentially demonstrates the intricate role of the hippocampus in navigating our social world. While most of the results are solid, the paper requires some further clarification.

eLife Assessment

This study presents a potentially valuable exploration of the role of thalamic nuclei in language processing. The results will be of interest to researchers interested in the neurobiology of language. However, the evidence is incomplete to support robust conclusions at this point.

eLife Assessment

This manuscript reports high-resolution cryo-EM structures of a trimethylamine N-oxide demethylase and advances the intriguing hypothesis that the enzyme is bifunctional, coupling TMAO demethylation to formaldehyde capture at a distal tetrahydrofolate-binding site via an enclosed intramolecular tunnel. Supported by biochemical assays and molecular dynamics simulations, the structural findings are valuable and potentially of broad interest, particularly the unusual oligomeric architecture and the proposed conduit for a reactive intermediate. However, the mechanistic framework is considered incomplete, raising substantial concerns regarding the proposed catalytic mechanism, metal/cofactor requirements, and the interpretation of biochemical data supporting formaldehyde channelling.

eLife Assessment

This study provides a useful contribution to understanding how wearable augmentation devices interact with human proprioception, using a longitudinal design over a single session. Results demonstrate that the perceptual representation of the biological finger and augmentation device changes across different phases of device exposure and use. The evidence supporting a representational change over time is solid, although it is still not clear whether these changes reflect three distinct phases of sensorimotor plasticity, as argued, versus 'washout' or adaptation effects. This work will be of interest to researchers studying body representation, sensorimotor learning, and human-technology interaction.

eLife Assessment

This paper investigates the Achilles' heel of an aggressive pediatric bone cancer known as Ewing sarcoma. The authors aimed to better understand how its previously undruggable drivers mediate oncogenic mechanisms using several omics approaches. Transcriptomic changes aligned with their findings provide convincing evidence for the role of a short alpha helix in the DNA binding domain of FLI1 in modulating binding to GGAA microsatellites and promoting enhancer activity. The study provides valuable new insights into the underlying oncogenic mechanisms in Ewing sarcoma.

eLife Assessment

This fundamental manuscript describes how the posterolateral cortical amygdala (plCoA) generates appetitive or aversive behaviors in response to odors. By combining optogenetic stimulation, single-cell RNA sequencing, and spatial analysis, the authors identify a topographically organized circuit within plCoA that governs these behaviors. The manuscript shows convincingly that multiple features (spatial, genetic, and projection) contribute to overall population encoding of valence. Overall, the authors conduct many challenging experiments, each of which contains the relevant controls, and the results are interpreted within the framework of their experiments.

eLife Assessment

This is an important study with direct implications for the rational selection of antimalarial drug combinations. The authors present data demonstrating antagonism between 4-aminoquinoline antimalarials and peroxide drugs under physiologically relevant conditions, including robust effects at the trophozoite stage and for chloroquine at the ring stage. While the conclusions are based on in vitro assays and further work will be needed to fully resolve the underlying mechanism, the findings are convincing and provide a strong rationale for evaluating drug combinations in relevant preclinical models prior to clinical testing.

eLife Assessment

In this study, the authors identify EOLA1 as a novel mitochondrial protein required for mitochondrial translation and normal cardiac function. The characterization of the molecular role of EOLA1 is still incomplete, and additional controls will be necessary. Nevertheless, the identification of a novel factor critical for mitochondrial gene expression and oxidative phosphorylation will be useful for cell biologists working on mitochondrial dysfunction.

eLife Assessment

This important study introduces a pulsed laser phase plate that generates stable phase contrast in electron microscopy, offering a practical alternative to continuous-wave designs that suffer from optical instabilities and diffraction artifacts. The experimental results demonstrate a controllable and stable electron phase shift, and the evidence supporting the feasibility of this approach for phase-contrast electron microscopy is convincing. Clarifying the agreement between experiment and theory and further elaborating on possible applications would strengthen the manuscript.

eLife Assessment

This important study reports an endometrial organoid culture system mimicking the window of implantation. The evidence supporting the conclusion drawn is convincing. The data will be of interest to embryologists and investigators working on reproductive biology and medicine.

eLife Assessment

The authors developed a fundamental computational method, which is intended to automatically process bioluminescence imaging-derived tumour images across anatomical regions and over time. This allows quantitative analysis of such data, and the authors applied it to describe the spatiotemporal distribution of tumour cells in response to CD19-targeted CAR-T cells that contained either CD28 or 4-1BB costimulatory domains. Some operational limitations were identified, which relate to the pipeline's reliance on predefined regions of interest instead of aligning signal sites with anatomical information, scaling, and limitations in taking animal pose into account. Overall, the authors provide compelling evidence for the functionality of their computational approach towards automated analysis of bioluminescence imaging data, while applying it to a current topic of wide interest in cell therapy research.

eLife Assessment

This valuable study presents a technically sophisticated intravital two-photon calcium imaging approach to characterize Ca²⁺ dynamics in distinct populations of meningeal macrophages in awake, freely behaving mice. These data are solid and suggest that meningeal macrophage calcium activity is tightly linked to anatomical sub-compartments, with potential implications for migraine and neuroinflammatory processes. Despite these strengths and broad relevance to neuroimmunology, several technical and interpretational issues limit the study, which could be addressed to strengthen this manuscript.

eLife Assessment

This study provides valuable evidence that hepatic DHHC7-dependent palmitoylation is a physiologically relevant regulator of systemic metabolism, and that loss of DHHC7 disrupts Gαi palmitoylation, activates cAMP-PKA-CREB signaling, and increases hepatic transcription and secretion of Prg4. The identification of Prg4 as a hepatokine that is elevated in vivo, together with some in vitro evidence for its interaction with GPR146, represents a conceptually novel contribution to the field. However, the evidence linking these mechanisms to systemic lipolysis, liver-adipose tissue crosstalk, and whole-body metabolic physiology remains incomplete, as the phenotypic analyses rely on a limited set of experiments and do not yet fully support claims regarding adipose tissue dysfunction or altered lipid flux.

eLife assessment

The manuscript presents important findings with theoretical or practical implications beyond a single subfield. The work is overall solid, and the methods, data, and analyses broadly support the claims. Although the novelty of this study and the work put into it are appreciated, there are also clearly some weaknesses that should be addressed.

eLife Assessment

This modelling study tests several hypotheses describing how seasonality and migration drive the epidemiology of Rift Valley Fever Virus among transhumant cattle in The Gambia. The work is methodologically solid, and the findings offer valuable insights into how the movement of cattle in and out of the Gambia River and Sahel ecoregions could lead to source-sink transmission dynamics among cattle subpopulations, sustaining endemic transmission.

eLife Assessment

This useful study examines whether the sugar trehalose, coordinates energy supply with the gene programs that build muscle in the cotton bollworm (Helicoverpa armigera). The evidence for this currently is incomplete. The central claim - that trehalose specifically regulates an E2F/Dp-driven myogenic program - is not supported by the specificity of the data: perturbations and sequencing are systemic, alternative explanations such as general energy or amino-acid scarcity remain plausible, and mechanistic anchors are also limited. The work will interest researchers in insect metabolism and development; focused, tissue-resolved measurements together with stronger mechanistic controls would substantially strengthen the conclusions.

eLife Assessment

This study offers important methodological advances for CRISPR-based mutagenesis in mice, highlighting the potential of founder animals for early phenotypic characterization. The authors present convincing evidence, supported by rigorous experimental design, that "crispant" (F0) analysis in mice, despite prior concerns about genetic mosaicism, can be utilized to assess protein function.

eLife Assessment

This study presents valuable data suggesting that ATP-induced modulation of alveolar macrophage (AM) functions is associated with NLRP3 inflammasome activation and enhanced phagocytic capacity. While the in vivo and in vitro data reveal an interesting phenotype, the evidence provided is incomplete and does not fully support the paper's conclusions. Additional investigations would be of value in complementing the data and strengthening the interpretation of the results. This study should be of interest to immunologists and the mucosal immunity community.

eLife Assessment

This fundamental study provides the first genome-wide characterization of H3K115 acetylation and identifies a striking and previously unappreciated association of this globular-domain histone modification with fragile nucleosomes at CpG island promoters, active enhancers, and CTCF binding sites. While the work is largely descriptive and correlative in nature the evidence is compelling. The authors present multiple, orthogonal genomic and biochemical analyses that consistently support their central conclusions.

eLife Assessment

This fundamental work substantially advances our understanding of OXT (oxytocin) neurons and OXTR (oxytocin receptor) expressions in mammalian brains using an advanced RNAscope at the single transcript level. The evidence supporting the conclusions is compelling using chromogenic assays and state-of-the-art microscopy. The work will be of broad interest to neuroscientists and endocrinologists.

eLife Assessment

This potentially important study explores the specificity of olfactory perceptual learning. In keeping with previous work, the authors found that learning to discriminate between two enantiomers does not generalize across the nostrils or to unrelated enantiomers, whereas learning to discriminate odor mixtures does generalize across the nostrils and to other odor mixtures, with this learning effect persisting over at least two weeks. While the evidence presented to support these findings is convincing, it remains unclear why the results differ for enantiomers and why training on odor mixtures generalizes to other odor mixtures.

eLife Assessment

This important study provides evidence, albeit still incomplete, that high-elevation species lose water at slower rates than low-elevation species. The findings imply that egg physiology may be a factor limiting the distributional range of bird species. While this work reinforces the need for all life stages to be considered when evaluating physiological adjustment to climate change, the analyses as presented by the authors do not clearly highlight the specific impact of species differences in influencing these adjustments.

eLife Assessment

In this manuscript, Jong et al. provide and validate a very useful resource for performing CRISPR screenings to study neutrophil differentiation and function by generating Hoxb8 cells that constitutively express Cas9. This library-screening approach has the potential to improve on the established lentiviral CRISPR-Cas9 editing of Hoxb8 cells. However, the technical advances provided are only incremental and the results presented in this study do not significantly further our understanding of these cells, but rather provide a good validation of their Cas9+ modified version.

eLife Assessment

This study reports an mRNA-based strategy for restoring sperm motility in a mouse model of monogenic male infertility. The work is technically innovative and potentially valuable, as it demonstrates feasibility of in vivo testicular mRNA delivery without genomic integration of foreign DNA. However, although partial recovery of sperm motility is supported, the evidence for meaningful restoration of fertility remains incomplete, with weak IVF outcomes and difficult-to-interpret ICSI results. In addition, mechanistic questions regarding the persistence of mRNA and the specificity of germ-cell targeting remain insufficiently resolved, limiting the strength of the authors' conclusions.

eLife Assessment

In their study, Scherer and colleagues aim to use analyses of single-cell clones of murine granulocyte monocyte progenitors that are conditionally immortalized, and analyses of neutrophils derived from those clones to characterize an experimental system for studying neutrophil heterogeneity. The multi-omic and functional analyses reported are valuable but the strength of the evidence presented in support of them is incomplete because the study lacks a rigorous demonstration that the neutrophil-like cells that they derive are fully mature neutrophils.

eLife Assessment

This important study tackles an interesting aspect of fungal physiology: how a mitochondria-associated gene influences production of the secondary metabolite DON and fungicide sensitivity. The authors have improved the manuscript and the supporting evidence is convincing, although some uncertainties remain around descriptions of the methods.

eLife Assessment

This study proposes a potentially useful improvement on a popular fMRI method for quantifying representational similarity in brain measurements by focusing on representational strength at the single trial level and adding linear mixed effects modeling for group-level inference. The manuscript provides solid evidence of increased sensitivity with no loss of precision compared to more classic versions of the method. However, several assumptions are insufficiently motivated, and it is unclear to what extent the approach would generalize to other paradigms.

eLife Assessment

This is an important study that provides compelling data from a diverse set of approaches from single cell transcriptome data and network analysis from genetically diverse mouse cells to identify novel driver genes underlying human GWAS associations. The authors present evidence that network analysis of scRNA-seq data from genetically diverse mouse bone-marrow derived stromal cells can be informative for identifying human BMD GWAS driver genes. Their approach should be broadly used and applicable to other GWAS studies.

eLife Assessment

This study presents a valuable finding on the neural representation of time from two distinct egocentric and allocentric reference frames. The evidence is solid and largely supports the hypothesis, with one caveat that the task differences could impact the observed effects. The work will be of interest to cognitive neuroscientists working on the perception and memory of time.

eLife Assessment

This manuscript describes a useful integrated proteogenomics pipeline to enable the discovery of novel peptides in cancer cell lines. The method combines long-read RNA sequencing with a multi-protease digestion and proteomics approach. The method is a further development of the authors' previous approaches to identify cancer-specific peptides; however, the current study focuses on a single cell line, and the characterization remains incomplete and lacks validation for candidate alterations. The manuscript will be of interest to scientists focusing on identifying unique alterations in cancer cells.

eLife Assessment

This study provides an important contribution by showing that whiteflies and planthoppers use salivary effectors to suppress plant immunity through the receptor-like protein RLP4, suggesting convergent evolution in these insect lineages. The topic is of clear interest for understanding plant-insect interactions and offers ideas that could stimulate further research in the field. The authors provide mostly solid evidence for the functional roles of the salivary effectors; however, the interpretation of the physiological function of RLP4 in plant defense requires clarification.

eLife Assessment

This study demonstrates that endothelial toll-like receptor 4 is a central regulator of leptomeningeal inflammation in the context of neonatal E. coli meningitis. The data are derived from cell type-specific gene knockout in mice as well as from cultured endothelial cells, and are generally solid, with only minor weaknesses in analysis and interpretation. This work is important as it advances our understanding of host cellular processes and molecular pathways underlying meningitis pathogenesis.

eLife Assessment

This fundamental study advances our understanding of how dietary patterns shape cancer immunity by identifying a link between a Mediterranean-mimicking diet, gut bacteria, and a metabolite that enhances anti-tumor immune responses. The evidence supporting the main conclusions is solid, based on carefully controlled diet experiments, measurements of gut-derived molecules, and functional immune analyses across multiple models, together with supportive observations in human data. The work will be of broad interest to biologists working on microbiota and cancer. However, there are several issues that the authors should address to improve the manuscript.

eLife Assessment

This study presents a valuable finding that depletion of the rRNA methyltransferase METTL5 enhances anti-tumor immunity through a novel mechanism involving neoantigen generation from non-canonical translation. The evidence supporting the central conclusions is solid, with comprehensive multi-omics data including ribosome profiling, immunopeptidomics, TCR sequencing, and multiple in vivo tumor models demonstrating synergy with immune checkpoint blockade.

eLife Assessment

The importance of uterine natural killer (NK) cells in reproductive success has been demonstrated in mice and humans; however, it is still unclear how uterine NK cells are developed. In this valuable manuscript, the authors provide convincing evidence that TGF-b signaling in NK cells supports normal pregnancy in mice by the conversion of conventional NK cells into uterine tissue-resident NK cells. There are some concerns about the paper, particularly around Figures 1A, 1C, and 2E.

eLife Assessment

This important study reports that the human posterior inferotemporal cortex (hPIT) functions as an attentional priority map, integrating both top-down and bottom-up attentional signals rather than serving solely as an object-processing region. The experiments and analyses are well conducted and provide compelling evidence that hPIT bridges dorsal and ventral attention networks and is robustly modulated by attention across diverse visual tasks. The study will be relevant for researchers investigating visual attention, high-level visual cortex, and the neural mechanisms that integrate endogenous and exogenous attentional control.

eLife Assessment

This is an important study that advances our understanding of the transition from quadrupedal to bipedal gait in a neuromechanical model of the Japanese macaque. The method and results are solid; the neuromusculoskeletal model successfully reproduces experimental data, and the stability analysis based on an inverted pendulum model effectively explains the effects of different transition strategies. However, the study would benefit from a more comprehensive sensitivity analysis. The findings are highly relevant for researchers in motor control, comparative physiology/biomechanics, and robotics.

eLife Assessment

Hoverflies are known for their sexually dimorphic visual systems and exquisite flight behaviors. This valuable study reports how two types of visual descending neurons differ between males and females in their motion- and speed-dependent responses, yet surprisingly, the behavior they control lacks any sexual dimorphism. The results convincingly support these findings, which will be of interest for studies of visuomotor transformations and network-level brain organization.

eLife Assessment

This valuable study reports results showing how different neurons in the dysgranular retrosplenial cortex code spatial orientation. Specifically, the paper reports that some neurons maintain tuning for a single head direction across multi-compartmental environments, while other neurons are tuned to different head directions that reflect the geometry within each compartment. The study was viewed as likely to expand the field's understanding of directional tuning of neurons, but incomplete evidence was provided to support the conclusions.

eLife Assessment

This important study substantially advances the imaging toolbox available to neuroscientists by presenting a tunable Bessel (tBessel-TPFM) platform that enables high-speed volumetric two-photon imaging. The evidence supporting the novel methodology is convincing, with rigorous benchmarking and demonstrations of a wide range of neuroimaging applications covering vascular dynamics, neurovascular coupling, optogenetic perturbation, and microglial responses. The work will be of broad interest to neuroscientists and imaging system tool developers.

eLife Assessment

The study investigates, from multiple angles, the still-debated function of insect rhodopsin-7 (Rh7). The authors present compelling results for its ancient phylogenetic origin across pan-arthropods, a non-visual role based on expression analyses in the fly brain, an unusual G-protein signalling pathway, and - using behavioural genetics - that Rh7 affects how Drosophila melanogaster interprets and responds to light-dark transitions. Through this, the work provides fundamental new insights into the evolution and function of non-visual opsins.

eLife Assessment

This study makes a valuable contribution to understanding how negative affect shapes food-choice decision making in bulimia nervosa by leveraging a mechanistic drift diffusion model to quantify the weighting of tastiness and healthiness attributes. The evidence is solid, supported by a randomized crossover design and generally appropriate statistical analyses. However, the interpretability of the findings is limited by ambiguities in the affect manipulation, particularly regarding whether neutral and negative inductions yielded reliably distinct affective states at the time of task performance in the bulimia nervosa group. Consequently, session-related differences in model parameters cannot be unequivocally attributed to negative affect rather than to uncontrolled state or contextual factors, and clearer separation of affective conditions alongside analyses aligned with the paired data structure would strengthen the conclusions.

eLife Assessment

This useful study raises interesting questions but provides inadequate evidence of an association between atovaquone-proguanil use (as well as toxoplasmosis seropositivity) and reduced Alzheimer's dementia risk. The findings are intriguing but they are correlative and hypothesis-generating with the strong possibility of residual confounding.

eLife Assessment

This important work establishes a connection between PRMT1 and SFPQ by identifying common phenotypes downstream of their inactivation. In the resubmission, authors now include NMD as a contributor to aberrant gene expression underpinning craniofacial development. The complementary experiments help strengthen some solid conclusions. This paper describes an interesting mechanism for the regulation of RNA levels, which is of interest to the readers of eLife.

eLife Assessment

This important study provides one mechanism that can explain the rapid diversification of poison-antidote pairs in fission yeast: recombination between existing pairs. The evidence is largely solid, but the study needs to tune down its claims (as it is not shown that the novel poison-antidote can serve as a meiotic driver), and to address small experimental requests. The work is of interest to scientists studying genetic incompatibilities.

eLife Assessment

This valuable study uses tools of population and functional genomics to examine long non-coding RNAs (lncRNAs) in the context of human evolution. Analyses of computationally predicted human-specific lncRNAs and their genomic targets lead to the development of hypotheses regarding the potential roles of these genetic elements in human biology. Compared to previous versions, the conclusions regarding evolutionary acceleration and adaptation have become more solid by more fully taking data and literature on human/chimpanzee genetics and functional genomics into account.

eLife Assessment

This important study provides evidence supporting the hypothesis that postnatal visual experience shapes the patterns of functional connectivity between extrastriate visual cortex and frontal regions, by comparing neonates, blind and sighted adults using resting-state fMRI. The evidence supporting the main claim is convincing, and the authors' interpretations are appropriately calibrated in the discussion. Nevertheless, the study design and methodology are inherently limited to resolve the underlying mechanisms driving connectivity changes during neurodevelopment (experience-related plasticity vs post-natal experience-independent maturation). This study will be of broad interest to neuroscientists and neuroimaging researchers studying vision, plasticity and brain development.

eLife Assessment

This important work describes wing mechanosensory neurons in detail, extending our understanding of sensorimotor processing in the fruit fly. The evidence presented convincingly supports the authors' identification of these neurons and leverages state-of-the-art methods to generate a near-complete map of wing mechanosensory circuitry. Overall, this study provides new hypotheses and invaluable tools for investigating proprioceptive motor control of the wing in Drosophila.

eLife Assessment

This important work examines the effects of side-wall confinement on chemotaxis of swimming bacteria in a shallow microfluidic channel. The authors present convincing experimental evidence, combined with geometric analysis and numerical simulations of simplified models, showing that chemotaxis is enhanced when the distance between the side walls is comparable to the intrinsic radius of chiral circular swimming near open surfaces. This study should be of interest to scientists specializing in bacteria-surface interactions.

eLife Assessment

This fundamental work reveals that the accessibility of the unstructured C-terminal tail of α-tubulin differs with the state of the microtubule lattice. Accessibility increases with the expansion of the lattice induced by GTP and certain MAPs, which can then dictate the subsequent interactions between MAPs and microtubules, and post-translational modifications of tubulin tails. The evidence supporting the conclusion is compelling, although the characterisation of the probes does not answer whether they directly affect the lattice or expose the C-terminal tail of α-tubulin. The probes can be used as tools in the future to study differences in microtubule lattice regulation under different conditions both in vitro and in vivo. This work will be of great interest to the cytoskeleton field.

eLife Assessment

In this important study, the authors conducted extensive sets of computational and investigations of the mechanism of cholesterol transport in the smoothened (SMO) protein. The computational component integrated multiple state-of-the-art approaches such as adaptive sampling, free energy simulations, and Markov state modeling, providing compelling support for the proposed mechanistic model, which is further validated with solid experimental mutagenesis data.

eLife Assessment

This study addresses a key, long-standing question about how visual feature selectivity is organized in mid-level visual cortex, using an ambitious combination of large-scale neural recordings and image synthesis. It provides important insights into the complexity of single-neuron selectivity and suggests a structured organization across cortical depth. While the evidence is generally solid and technically impressive, several key claims would be strengthened by additional controls, particularly regarding the sources of similarity across neurons and the dependence of the results on modeling choices.

eLife Assessment

There is a perennial question in the field of birdsong: the contribution of the cerebellum to singing and processing song-related information. This study provides a valuable first step into this discussion, using electrophysiology of cerebellar neurons during a battery of assays, including singing and song playback. While the electrophysiological dataset here is novel and could shed light on key aspects of the neural control of vocal behavior, the evidence provided for the conclusions reached by the authors is currently incomplete.

eLife Assessment

This study makes a valuable contribution to our understanding of how the lipase regulator ABHD5 may control lipase activity through interactions with lipid droplets and cellular membranes. By combining multiscale molecular dynamics simulations with experimental approaches, the authors provide novel molecular insights into this membrane-protein interaction and present evidence suggesting that the regulatory mechanism depends on protein conformational changes and local membrane remodeling. While much of the evidence supporting the main conclusions is convincing, several aspects of the analysis, interpretation, and discussion remain incomplete. Overall, this work will be of interest to structural and molecular biologists working on lipid metabolism and membrane biophysics.
