This fundamental work has the potential to advance our understanding of brain activity using electrophysiological data, by proposing a completely new approach to reconstructing EEG data that challenges the assumptions typically made in the solutions to Maxwell’s equations. Convincing evidence for the superior spatio-temporal resolution of this method is provided through a number of experiments, including simultaneous FMRI/EEG acquisitions. This work will be of broad interest to neuroscientists and neuroimaging.

eLife Assessment

The authors investigated the mechanisms underlying the pause in striatal cholinergic interneurons (SCINs) induced by thalamic input, identifying that Kv1 channels play a key role in this burst-dependent pause. The experimental evidence is convincing.<br /> The study provides important mechanistic insights into how burst activity in SCINs leads to a subsequent pause, highlighting the involvement of D1/D5 receptors.

eLife Assessment

This timely and important study used functional near-infrared spectroscopy hyperscanning to examine the neural correlates of how group identification influences collective behavior. The work provides solid evidence to indicate that the synchronization of brain activity between different people underlies collective performance and that changes in brain activity patterns within individuals may, in turn, underlie this between-person synchrony, although the order in which different task stages were completed could not be counter-balanced. This study will be of interest to researchers investigating the neuroscience of social behaviour.

eLife Assessment

This manuscript presents a clever and powerful approach to examining differential roles of Nav1.2 and Nav1.6 channels in excitability of neocortical pyramidal neurons, by engineering mice in which a sulfonamide inhibitor of both channels has reduced affinity for one or the other channels. Overall, the results in the manuscript are compelling and give important information about differential roles of Nav1.6 and Nav1.2 channels. Activity-dependent inactivation of NaV1.6 was also found to attenuate seizure-like activity in cells, demonstrating the promise of activity-dependent NaV1.6-specific pharmacotherapy for epilepsy.

eLife Assessment

This study presents a valuable investigation into how heavy metal stress may have influenced the domestication of maize from its wild ancestor, teosinte parviglumis, focusing on specific ATPase genes with proposed roles in heavy metal homeostasis. The evidence supporting the main claims is incomplete, with suggestive but not definitive data linking gene function to domestication traits, and limited environmental context for the hypothesized selection pressures. While the work introduces an interesting model connecting environmental stress responses to evolutionary transitions and highlights underexplored aspects of teosinte plasticity, the conclusions would benefit from more comprehensive analyses such as transcriptomics, a broader survey of loci, and stronger paleoenvironmental validation. The study will be of interest to researchers in plant evolution and domestication, but currently lacks the analytical depth to fully support its central hypothesis.

eLife Assessment

This study presents valuable findings about daily rhythm changes of the Drosophila melanogaster adult gut metabolome, which is shown to be dependent on the circadian clock genotype, dietary regime and composition, and gut microbiota. The phenomena observed are supported by convincing experimental evidence. The general descriptive approach limits the power of the proposed conclusions. The work will be of interest to a broad range of physiology specialists

eLife Assessment

This study introduces a novel and broadly applicable metric-phenological lag-to partition the effects of spring warming from other abiotic constraints on plant phenology. While the dataset is extensive and the analytical framework is valuable conceptually, the manuscript lacks clarity in its aims and justification for the new metric, and key results are underdeveloped or poorly visualized. The strength of evidence is moderate to solid, but revisions are needed to clarify the study's contribution and improve interpretability.

eLife Assessment

This is a potentially important study that explores the relevant range of parameter values for calibration and validation of cardiac electromechanics in ventricular models. Although much of the work presented is solid, the evidence provided to support the authors' key scientific claims is incomplete, especially as it relates to the emphasis on standardized validation and verification approaches. Notably, the level of model personalization presented in this work falls short of the threshold for what could reasonably be called a "digital twin", even by the relatively relaxed standards that have emerged in computational physiology and related fields in recent years.

eLife Assessment

This study presents significant and novel insights into the roles of zinc in mammalian meiosis/fertilization events. These findings are useful to our understanding of these processes. The evidence presented is solid, with experiments being well-designed, carefully described, and interpreted with appropriate rigor.

eLife Assessment

Inspired by bee's visual behavior, the goal of the manuscript is to develop a model of visual scanning, visual processing and learning to recognize visual patterns. In this model, pre-training with natural images leads to the formation of spatiotemporal receptive fields that can support associative learning. Due to an incomplete test of the necessity and sufficiency of the features included in the model, it cannot be concluded that the model is either the "minimal circuit" or the most biologically plausible circuit of this system. With a more in-depth analysis, the work has the potential of being important and very valuable to both experimental and computational neurobiologists.

eLife Assessment

In their valuable study, Bracey et al. investigate how microtubule organization within pancreatic islet beta cells supports optimal insulin secretion. Using a combination of live imaging and photo-kinetic assays in an in vitro culture system, they provide compelling evidence that kinesin-1-mediated microtubule sliding, which plays critical roles in neurons and embryos, also plays a critical role in forming the sub-membranous microtubule band in response to glucose in beta cells. This work will be of interest to cell biologists studying cytoskeletal dynamics and organelle trafficking, as well as to translational biologists focused on diabetes.

eLife Assessment

This fundamental study provides new insights into the maturation of ribbon synapses in zebrafish neuromast hair cells. Live-cell imaging and pharmacological and genetic manipulations together provide compelling evidence that the formation of this synaptic organelle is a dynamic process involving the fusion of presynaptic elements and microtubule transport, though the evidence that ribbon precursors move in a directed motion toward the active zone is less persuasive. These findings will be of interest to neuroscientists studying synapse formation and function and should inspire further research into the molecular basis for synaptic ribbon maturation.

eLife Assessment

This useful manuscript describes cryo-EM structures of archaeal proteasomes that reveal insights into how occupancy of binding pockets on the 20S protease regulates proteasome gating. The evidence supporting these claims is convincing, although inclusion of more quantitative comparisons would help strengthen the conclusions. This work will be of special interest to researchers interested in proteasome structure and regulation.

eLife Assessment

The findings in this manuscript are fundamental because they identify an entry receptor MYL3 that belongs to the myosin family as a possible target that could inhibit a virus that has a high impact on aquaculture. The evidence is convincing as it contains strong in vitro and in vivo data that support their conclusions; however, studies on the presence of MYL3 in NNV target tissues will further strengthen their claims

eLife Assessment

This valuable study provides in-vivo evidence that CCR4 regulates the early inflammatory response during atherosclerotic plaque formation. The authors propose that altered T-cell response plays a role in this process, shedding light on mechanisms that may be of interest to medical biologists, biochemists, cell biologists, and immunologists. The work is currently considered incomplete pending textual changes and the inclusion of proper controls.

eLife Assessment

This study presents a new, fundamental finding to the field interested in recurrent processing and its neuromodulatory underpinnings, finding unexpectedly that memantine (blocking NMDA-receptors) enhances the decoding of features thought to rely on NMDA-receptors. This interesting, compelling result identifies new directions for researchers studying consciousness, sensory processing, attention, and neurotransmitters.

eLife Assessment

This is a fundamental cell biological study of host responses during symbiotic microbial infection of plants. Compelling imaging-based approaches using genetically encoded cell cycle markers show that in Medicago truncatula root cortex cells, early rhizobial infection events are associated with cell-cycle re-entry, but once the infection is established, host cells exit the cell cycle. The work will be of interest to a wide range of readers working in fields from development and cell biology to plant-microbe interactions.

eLife Assessment

In this convincing work by Yamaguchi et al. the cryo-EM structure of the heterohexameric 3:3 LGI1-ADAM22 complex is presented. The findings suggest that LGI1 can cluster ADAM22 in a trimeric fashion. The clustering of cell surface proteins is important in controlling signaling in the nervous system. This new version of the manuscript has been improved substantially and the figures have been enhanced and clarified.

eLife Assessment

This solid study assesses a mitochondrial polymerase inhibitor in combination with the BCL-2 inhibitor venetoclax, with the aim to increase the elimination of acute myeloid leukemia. It provides valuable findings of combinatorial efficacy using preclinical models in vitro and in vivo, confirming the overall importance of targeting oxidative phosphorylation to overcome venetoclax resistance in acute myeloid leukemia, and could be strengthened through mechanistic studies demonstrating on target effects and pharmacodynamic efficacy in vivo. The study is of interest to hematologists because it addresses a key biomedical issue in acute myeloid leukemia (venetoclax resistance) and provides data regarding the safety and activity of a novel inhibitor of the mitochondrial polymerase in combination with venetoclax.

eLife Assessment

The study presents extensive gene expression profiling and bioinformatic analyses, offering insights into the roles of fibroblasts in cardiac development. The large volume of scRNA-seq data is both compelling and important to the scientific community. All three reviewers agree that the revised manuscript represents a significant improvement and addresses most, if not all, of their previous concerns. The reviewers also acknowledge that detailed mechanistic studies on how fibroblast-derived collagen regulates myocardial and coronary vasculature development are beyond the scope of the current study.

eLife Assessment

This work demonstrates the therapeutic potential of recombinant human PDGF-AB/BB proteins in alleviating the senescent signatures of primary human intervertebral disc cells. The study represents a fundamental, significant advance in the treatment of intervertebral disc degeneration through the suppression of senescence. The strength of evidence supporting these conclusions is compelling, as it is primarily based on transcriptomic analysis and direct protein measurements from relatively homogeneous cell populations. This work will be of interest to spine basic scientists and clinicians, as well as to musculoskeletal scientists more broadly. The revised manuscript adds greater clarity, and the impact of the study is greatly enhanced.

eLife Assessment

This study presents important new insights linking obesity to kidney disease using a Drosophila model. A series of compelling experiments demonstrate that a high-fat diet induces excretion of a leptin-like JAK-STAT ligand from fat body, driving the adipose-nephrocyte axis through activated JAK-STAT signaling and subsequently causing a functional defect in nephrocytes. The approach using combination of genetic tools and pharmacological intervention is solid and confirms the mechanistic link, together with phenotypic analysis that further supports the authors conclusions.

eLife Assessment

Using microscopy experiments and theoretical modelling, the authors present convincing evidence of cellular coordination in the gliding filamentous cyanobacterium Fluctiforma draycotensis.

eLife Assessment

This fundamental work by Yamamoto and colleagues advances our understanding of how positional information is coordinated between axes during limb outgrowth and patterning. They provide solid evidence that the dorsal-ventral axis feeds into anterior-posterior signaling, and identify the responsible molecules by combining transplantations with molecular manipulations. This work will be of broad interest to regeneration, tissue engineering, and evolutionary biologists.

eLife Assessment

This valuable study investigates how stochastic and deterministic factors are integrated during cellular decision-making, particularly in situations where cells differentiate into distinct fates despite being exposed to the same environmental conditions. The authors present convincing evidence that gene expression variability contributes to the robustness of cell fate decisions in D. discoideum, which sheds light into the role of stochasticity during cell differentiation.

eLife Assessment

The manuscript explores how bacterial evolution in the presence of lytic phages modulates b-lactams resistance and virulence properties in methicillin-resistant Staphylococcus aureus (MRSA). This important work improves our knowledge of how mutation in genes required for phage infection confers sensitivity to b-lactams and alter virulence properties. Altogether, the findings are convincing.

eLife Assessment

The manuscript explores how bacterial evolution in the presence of lytic phages modulates b-lactams resistance and virulence properties in methicillin-resistant Staphylococcus aureus (MRSA). The work is valuable as it identifies underlying mutations that may confer sensitivity to b-lactams and alter virulence properties. While the findings are generally convincing, additional experiments linking how particular mutations regulate phenotypic changes are required to improve the work mechanistically.

eLife Assessment

The study by Power and colleagues is important, as elucidating the dynamic immune responses to photoreceptor damage in vivo potentiates future work in the field to better understand the disease process. The evidence supporting the authors' claims is compelling.

eLife Assessment

This study shows that a peptide called galanin can decrease or increase seizure activity in experimental models of seizures depending on the model. The authors use zebrafish and several methods to address the effects of galanin. The study will be useful to researchers who use zebrafish as experimental animals and who are interested in how peptides like galanin regulate seizures. However, the strength of evidence was considered incomplete at the present time due to several limitations of the results.

Editors Assessment:

This Data Release paper presents the first genome assembly of the lemon sole (Microstomus kitt), a commercially important flatfish found in European coastal waters. It is also interesting that this work was carried out in a University course setting involving the students. The resulting chromosome-level genome was assembled using long-read PacBio HiFi sequencing and the Hi-C technique. The 628 Mbp reference (which is consistent with other Pleuronectidae fish species) is assembled into 24 chromosome-length scaffolds with high completeness, achieving a scaffold N50 of 27.2 Mbp. Peer review and data curation made the author clarify a few points and share all of the data and results in an open and well curated manner. The annotated genome of the lemon sole, with its high continuity, should therefore provide important reference data for future population genetic analyses and conservation strategies of this organism.

This evaluation refers to version 1 of the preprint

eLife Assessment

This fundamental study identified a novel role of NOLC1 in regulating p53 nuclear transcriptional activity and p53-mediated ferroptosis in gastric cancer. After major revisions, the evidence supporting the conclusions is solid. However, some new experiments are needed to draw more robust conclusions regarding the ferroptosis-associated studies.

eLife Assessment

This manuscript describes an important finding of the transcriptional control of a chimeric gene transfer agents (GTA) cluster in Bartonella by a processive anti-termination factor (BrrG). The evidence provided is convincing. This manuscript will interest researchers working on transcriptional regulation, horizontal gene transfer, and phages.

eLife Assessment

This valuable study presents findings on the role of the small GTPase Rab3A in homeostatic plasticity. While the study provides solid evidence for a requirement of Rab3A in homeostatic up-scaling in cultured mouse neurons, it does not provide a model of how Rab3A is involved in homeostatic plasticity. The work will be of interest to researchers in the field of synaptic transmission and synaptic plasticity.

eLife Assessment

This valuable work uses serial block face electron microscopy to reconstruct detailed morphologies of large populations of Drosophila sensory neurons to determine the degree of diversity both within and across distinct neuronal populations. The authors convincingly show that there is considerable morphological diversity even within classes, and develop testable hypotheses about how arbors are optimized for particular sensory function and physiology. This work will be of interest to biologists working in physiology, insect chemosensation, and neuroscience.

eLife Assessment

This manuscript makes a valuable contribution to the field by uncovering a molecular mechanism for miRNA intracellular retention, mediated by the interaction of PCBP2, SYNCRIP, and specific miRNA motifs. The findings are convincing and advance our understanding of RNA-binding protein-mediated miRNA sorting, providing deeper insights into miRNA dynamics.

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 incomplete evidence suggests that Uev1a works with the E3 ligase APC/C to degrade Cyclin A, and the strength of evidence could be increased by addressing the expression of CycA in the ovaries and the uev1a loss of function in human cancer cells. This work would be of interest to researchers in germline biology and cancer.

eLife Assessment

This study presents a useful finding on the effects of arginine vasopressin (AVP) on islet cells in pancreatic tissue slices, using technically sophisticated spatio-temporal calcium recordings to confirm that AVP influences α and β cells differently depending on glucose concentrations. While the study’s methods – particularly the calcium imaging techniques and peptide ligand design targeting V1b receptors – are strong, the reviewers were concerned about several aspects of the experimental design. The results on β-cell responses are incomplete and insufficient to support the manuscript’s claims, especially due to the high variability of islet responses and lack of mechanistic and functional (hormone release) data. There are also concerns about the possibility of off-target effects and suboptimal receptor specificity: the study would be significantly strengthened by inclusion of signaling pathway interrogation, hormone output assays, genetic validation (e.g., β cell-specific deletion of V1br), and receptor localization. The work will still be of interest to researchers studying islet physiology in the context of health and diabetes.

eLife Assessment

The authors present a computational pipeline for the identification of endogenous allosteric modulators of GPCRs, with experimental validation performed in a yeast system. This approach is valuable for a broad audience, including GPCR structural biologists, molecular pharmacologists, and computational biophysicists. However, the rigor of the computational methods needs to be strengthened to provide stronger evidence for the study's conclusions, which is currently incomplete. The authors should justify their methodological choices and provide greater detail and clarity regarding each computational layer of the pipeline.

eLife Assessment

This valuable study addresses the role of sphingolipid metabolism in maintaining endolysosomal membrane integrity and its impact on tau pathology in Caenorhabditis elegans and human cell culture models. The methods are solid and the proposed mechanisms are conceivable. However, the current evidence is incomplete and could be strengthened, due to reliance on imaging data and insufficient biochemical validation. The work will be of broad interest to cell biologists and biologists working on Alzheimer's disease and related proteinopathies.

eLife Assessment

Using advanced CryoEM and mass spectrometry, the authors provide compelling evidence of how tubule formation occurs in an oxygen-dependent manner. These fundamental findings offer a novel mechanism by which rubrerythrin tubules encapsulate encapsulin to prevent oxidative stress in Pyrococcus furiosus. However, there are a few reasonable concerns about biochemical validations and the lack of adequate description of results and methodology.

eLife Assessment

This study presents compelling evidence that the denitrosylase SCoR2 regulates cardioprotective metabolic reprogramming in the heart following ischemia/reperfusion injury. The findings are supported by a novel multi-omics approach and the integration of mouse and human data, which provides valuable insights into S-nitrosylation and cardiac metabolism. However, some conclusions remain limited by unresolved methodological issues that warrant clarification.

eLife Assessment

This important study advances our understanding of population-level immune responses to influenza in both children and adults. The strength of the evidence supporting the conclusions is compelling, with high-throughput profiling assays and mathematical modeling. The work will be of interest to immunologists, virologists, vaccine developers, and those working on mathematical modeling of infectious diseases.

eLife Assessment

This manuscript focuses on developing a structural model of how the multidomain ECM protein SVEP1 enables Angiopoietin (ANG) binding to the orphan receptor TIE1, resulting in downstream receptor phosphorylation and signaling. This is a potentially important study, however, it currently lacks key controls and is therefore incomplete. The data will be of interest to scientists working in vascular biology and RTK signaling.

eLife Assessment

Engineering of adeno-associated virus (AAV) replication proteins may provide new insights into Parvoviral replication. The authors created a useful collection of Rep protein variants with changes that alter the amino acid sequence, but these did not lead to clear improvements in how the virus worked. Instead, their screen showed that changes that do not alter the protein ("synonymous" mutations) and changes to the promoter were more common. As it stands the results are incomplete due to potential issues with the screening design. We encourage a more complete characterization, which may enhance the translational potential of the approach.

eLife assessment

This important study investigates the adaptability of prey capture by archerfish, which hunt insects by spitting at them and then rapidly turning to reach their landing point on the water surface. The results of elaborate behavioral experiments and measurements show that, even though the visuomotor behavior unfolds very rapidly (in less than 100 ms), it is not hardwired and can adapt to different simulated physics and different prey shapes. The data are convincing and should be of relevance to those interested in rapid decision making in general, beyond the archerfish model.

eLife Assessment

This manuscript reports a useful computational study of information encoding across the monkey prefrontal and pre-motor cortices during decision making. While many of the conclusions are supported with solid analyses, the evidence for the main interpretation of the results, the role of an information bottleneck across areas, is not complete. The results will be of interest to a systems and computational neuroscience audience.

eLife Assessment

This important work substantially advances our understanding of reactive oxygen species (ROS) as a regenerative signal during postnatal cerebellum repair by activating adaptive progenitor reprogramming. The evidence supporting the conclusions is compelling, with rigorous genomic assays and in vivo analyses. This work will be of broad interest to biologists working on stem cells, neurodevelopment and regenerative medicine.

eLife Assessment

This study presents a valuable observation of how deletion of a major repair protein in bacteria can facilitate the rise of mutations that confer resistance against a range of different antibiotics. The data presented are convincing, and the authors addressed the concerns raised by the reviewers in their resubmission, improving the strength of their findings.

eLife Assessment

The authors provide a valuable contribution by documenting the role of microglia in pruning the axon terminals of AgRP neurons. The analysis of microglial axonal pruning is solid; however, the analysis of the effects inhibiting microglia on subsequent food consumption is not fully complete.

eLife Assessment

By performing a chemical screen of an FDA-approved library of small molecules against a leucine-dependent Mtb strain, this work discovered that semapimod inhibits Mtb growth by impairing leucine import. The work is useful because it connects leucine uptake with the cell wall lipids in Mtb; however, it remains incomplete as the evidence supporting semapimod's ability to target leucine uptake needs more substantial proof. The work requires significant experimental evidence to identify leucine transporter(s) and determine how PDIM participates in leucine uptake.

eLife Assessment

This useful study shows a protective role of type 1 IFN during Mycobacterium tuberculosis infection. It shows that the type 1 IFN response in human skin TST inversely correlates with TB severity, suggesting its protective role. Considering that type I IFN is usually shown to be pro-pathogenic, the higher vulnerability of zebrafish larvae lacking stat2 to M marinum infection is a strong result. However, the conclusion that IFN-I is protective during mycobacterial infection remains indirect and incomplete; the study requires additional mechanistic insights and validation.

eLife Assessment

This study presents an alternative to conventional and UV-based tetramers, which are easy to use and reliable for the identification of antigen-specific CD8 T cells. The authors demonstrate that tetramers for HLA alleles A0301, A1101, B0702, and C0702 can be subjected to specific temperatures that facilitate peptide exchange, whilst maintaining structural integrity. Whilst the strength of the evidence is currently incomplete, further development and validation of this approach is likely to provide a useful alternative to generating reagents for examining T cell specificities.

eLife Assessment

This study presents an important finding linking the bacterial metabolite trimethylamine and its receptor to circadian rhythms and olfaction. The current evidence supporting the claims of the authors is convincing, although further data and improvements to the presentation would further increase the impact of these results. This work will be of broad interest to researchers interested in nutrition, microbial metabolism, circadian rhythms, and host-microbiome interactions.

eLife Assessment

Endothelial cell-specific loss of TGF-beta signaling in mice leads to CNS vascular defects, specifically impairing retinal development and promoting immune cell infiltration. The data are solid, showing that loss of TGF-beta signaling triggers vascular inflammation and attracts immune cells specific to CNS vasculature, but there are issues with the single-nucleus RNA sequencing of immune cells. These findings are valuable, highlighting TGF-beta's role in maintaining vascular-immune homeostasis and its therapeutic potential in neurovascular inflammatory diseases.

eLife Assessment

This important study provides converging results from complementary neuroimaging and behavioral experiments to identify human brain regions involved in representing regular geometric shapes. Geometric shape concepts are universally present across diverse human cultures and possibly essential for unique human capabilities such as numerical cognition and symbolic reasoning, and identifying the brain networks involved in geometric shape representation is of broad interest to researchers studying human visual perception, reasoning, and cognitive development. The provided experimental evidence regarding the presence of geometric shape regularity representation in dorsal parietal and prefrontal cortex is solid, but the claimed link with mathematical reasoning, the influence of experimental tasks, and the role of experience in driving geometric shape representation in both humans and artificial vision models require further elucidation.

eLife Assessment

This fundamental study combines in vitro reconstitution experiments and molecular dynamics simulations to elucidate how membrane lipids are transported from the outer to the inner membrane of mitochondria. The authors provide convincing evidence that a positive membrane curvature is critical for membrane lipid extraction. The work will be of broad interest to cell biologists and biochemists.

eLife Assessment

This is a very important study in which the authors have modified ChIP-seq and 4C-seq with a urea step, which drastically changes the pattern of chromatin interactions observed for SATB1, but not other proteins (including CTCF). The study highlights that the urea protocols provide a complementary view of protein-chromatin interactions for some proteins, which can uncover previously hidden, functionally significant layers of chromatin organization. If applied more widely, these protocols may significantly further our understanding of chromatin organization. The study's findings are supported by a wealth of controls, making the evidence compelling.

eLife Assessment

This useful modeling study shows how spatial representations, similar to those seen in experimental data, emerge in a recurrent neural network trained on a navigation task. The training required path integration and decodability but did not rely on grid cell inputs. The network modeling is solid, though the link to experimental data could be strengthened.

eLife Assessment

The study investigated the effects of the peptide galanin on brain Ca2+ activity in zebrafish, which provides a useful model organism for whole-brain imaging because of its transparency. They found that galanin has distinct effects on hyperactivity and expression of galanin changes after activity increases. The strength of evidence was incomplete particularly for some of the conclusions regarding the use of convulsants and relevance to epilepsy because of limitations to the methods and interpretations of results.

eLife Assessment

The authors investigated KLF Transcription Factor 16 (KLF16) as an inhibitor of osteogenic differentiation, which plays a critical role in bone development, metabolism and repair. The results of the study are valuable as they could help to facilitate future research on the regulation of osteogenesis in vitro and in vivo. However, the evidence overall is incomplete, as validation by knockout mouse models would help to strengthen the conclusions.

eLife Assessment

This useful study presents a virtual reality-based contextual fear conditioning paradigm for head-fixed mice. Solid evidence supports the claim that the reported methods provide a reliable paradigm for studying contextual fear conditioning in head-fixed mice. The approach provides a way to perform multiphoton imaging of neural circuits, and other techniques that are typically performed in head-fixed animals, during behaviors that have traditionally been studied in freely moving animals.

eLife Assessment

This valuable study by Guo and colleagues reports the inhibitory activity of caffeic acid phenethyl ester (CAPE) against TcdB, a key toxin produced by Clostridioides difficile. C. difficile infections are a major public health concern, and this manuscript provides interesting data on toxin inhibition by CAPE, a potentially promising therapeutic alternative for this disease. The strength of the evidence to support the conclusions is solid, with some concerns about the moderate effects on the mouse infection model and direct binding assays of CAPE to the toxin.

eLife Assessment

This manuscript provides an important biochemical analysis of p53 isoforms, highlighting their aggregation propensity, interaction with chaperones, and dominant-negative effects on p53 family members. The authors have substantially strengthened the original manuscript by incorporating new mass spectrometry data and clarifying isoform-specific oligomerization behavior. Although the use of high expression levels limits direct physiological interpretation, the work is carefully framed as an investigation of protein misfolding and stability. Overall, this study offers convincing insights into p53 isoform biophysics with broad implications for cancer biology.

eLife Assessment

This study presents an advance in efforts to use histone post-translational modification (PTM) data to model gene expression and to predict epigenetic editing activity. Such models are broadly useful to the research community, especially ones that can model and predict epigenetic editing activity, which is novel; additionally, the authors have nicely integrated datasets across cell types into their model. The work is mostly solid, but it would be strengthened by performing further comparisons to existing methods that predict gene expression from PTM data and from more comprehensive functional validation of model-predicted epigenome editing outcomes beyond dCas9-p300 based perturbations. This work will be of interest to the epigenetics and computational modeling communities.

eLife Assessment

This study, which includes additional experiments in response to the reviewer comments, presents valuable findings illustrating the role of PI3Kα in heterotopic ossification in FOP model mice. The methods, data, and analyses are solid and generally support the claims although as noted by one of the reviewers, there is no data demonstrating the effect of BYL79 on cell growth, and it remains unclear whether BYL79 also inhibits the Smad2/3 pathway. While this study provides new insights into the role of the PI3Kα pathway as a therapeutic target for FOP, questions about the mechanism of BYL79 still exist.

eLife Assessment

Using a unique cerebellar disruption approach in non-human primates, this study provides valuable new insight into how cerebellar inputs to the motor cortex contribute to reaching. The findings convincingly demonstrate that reaching movements following cerebellar disruption slow down because of both an acute deficit in producing muscle activity as well as a progressive decline in compensating for limb dynamics. This work will be of interest to neuroscientists and clinicians interested in cerebellar function and pathology.

eLife Assessment

By using sparse Cre-dependent deletion of GluN1 subunit, in vitro quadruple patch clamp recordings, and pharmacological interventions, the authors show that spike timing dependent plasticity at between L5 synapses in the mouse visual cortex is: (i) dependent on presynaptic NMDA receptors; (ii) mediated by non-ionotropic NMDA receptor signaling, and (iii) reliant on presynaptic JNK2/Syntaxin-1a interactions. These fundamental findings advance our understanding of the molecular mechanisms underlying spike time dependent plasticity. The data are compelling and are supported by the elegant application of sophisticated experimental approaches.

eLife Assessment

This study presents valuable findings that advance our understanding of mural cell dynamics and vascular pathology in a zebrafish model of cerebral small vessel disease. The authors provide compelling evidence that partial loss of foxf2 function leads to progressive, cell-intrinsic defects in pericytes and associated endothelial abnormalities across the lifespan, leveraging powerful in vivo imaging and genetic tools. The strength of evidence could be further improved by additional mechanistic insight and quantitative or lineage-tracing analyses to clarify how pericyte number and identity are affected in the mutant model.

eLife Assessment

This study identifies 53BP1 as an interaction partner of GMCL1 (a likely CUL3 substrate receptor). The study seeks to link this finding to regulation of the mitotic surveillance pathway and paclitaxel resistance in cancer. The evidence for these claims is currently inadequate; concerns include the use of cell lines that have been reported to lack the mitotic surveillance pathway, insufficient consideration of paclitaxel mechanisms of action, and an overinterpretation of correlative results.

eLife Assessment

This valuable study expands the inventory of polyadenylated RNAs cleaved by the double-stranded RNA endonuclease Rnt1 in budding yeast, using solid methodology based on high-throughput sequencing. Previous studies had anecdotally discovered mRNA substrates, and this global characterization is comprehensive with multiple complementary controls. However, the study would be stronger with a deeper investigation into the biological function of Rnt1, as well as experiments directly probing the interaction between Rnt1 and its putative substrates.

eLife Assessment

Complex traits are influenced by genes and the environment, but especially the latter is difficult to pin down. This important study uses C. elegans to demonstrate that non-genetic differences in gene expression, partly influenced by the environment, correlate with individual differences in two reproductive traits. This supports the use of gene expression data as a key intermediate for understanding complex traits. The clever study design makes for compelling evidence, which is further strengthened by experimental confirmation that identified differentially expressed genes indeed influence these traits.

eLife Assessment

This useful study presents the potentially interesting concept that LRRK2 regulates cellular BMP levels and their release via extracellular vesicles, with GCase activity further modulating this process in mutant LRRK2-expressing cells. However, the evidence supporting the conclusions remains incomplete, and certain statistical analyses are inadequate. This work would be of interest to cell biologists working on Parkinson's disease.

eLife Assessment

This fundamental study advances our understanding of the role that energy metabolism, specifically anaerobic glycolysis, plays during retinal development. Convincing in vitro genetic and pharmacological evidence demonstrates that glycolytic flux controls retinal progenitor cell proliferation rates and the timing of photoreceptor maturation. Interesting evidence suggests potential downstream roles for intracellular pH and Wnt/β-catenin signaling; however, more direct evidence is needed to show they are the key mechanisms through which glycolytic flux regulates retinogenesis in vivo. This work is expected to stimulate broad interest and possible future studies investigating the link between metabolism and development in other tissue systems.

[Editors’ note: Primary data for this manuscript are not available due to a corrupted hard drive that occurred during the course of peer review. However, preprocessed data are available.]

eLife Assessment

This landmark study describes the structure of the human RAD51 filament with a recombination intermediate called the displacement loop (D-loop). Using cryogenic structural, biochemical, and single-molecule analyses, the authors provide compelling evidence on how the RAD51 filament promotes strand exchange between single-stranded and double-stranded DNAs. The work will be of interest to the community of homologous recombination and DNA repair, as well as genome stability more generally.

eLife Assessment

This important study by Lee et al. investigates the heterogeneous response of non-growing bacteria to the antimicrobial peptide (AMP) tachyplesin. In this response, a subpopulation of bacteria limits the accumulation of a fluorescent analog of the AMP, avoiding lethal damage. The study provides compelling evidence of the reduced susceptibility to the antimicrobial peptide antibiotic tachyplesin in a subpopulation of cells characterized by reduced drug accumulation. The evidence on the underlying molecular mechanisms is solid.

eLife Assessment

This is a well-written important paper on the recovery of fauna and flora following the end-Permian extinction event in several continental sites in northern China. The convincing conclusion, a rapid recovery in tropical riparian ecosystems following a short phase of hostile environments and depauperate biota, is supported by an impressive amount of data from sedimentology, body fossils of animals and plants, and especially trace fossils.

eLife Assessment

This study provides a comprehensive exploration of the role of hypothermia of mitigating IL1beta induction and NETosis in the context of lung injury induced by mechanical ventilation. The data are convincing, and the study is important for the field.

eLife Assessment

This important work advances our understanding of CHMP5's role in regulating osteogenesis through its impact on cellular senescence. The evidence supporting the conclusion is convincing and the revised manuscript is largely improved. This paper holds potential interest for skeletal biologists who study the pathogenesis of age-associated skeletal disorders.

eLife Assessment

This manuscript introduces a useful protein-stability-based fitness model for simulating protein evolution and unifying non-neutral models of molecular evolution with phylogenetic models. The model is applied to four viral proteins that are of structural and functional importance. The justification of some hypotheses regarding fitness is incomplete, as well as the evidence for the model's predictive power, since it shows little improvement over neutral models in predicting protein evolution.

eLife Assessment

This study presents a valuable assessment of increased similarity in visual appearance combined with an increased chemical difference between two butterfly species in sympatry compared with differences between three populations of one of the two species in allopatry. While the evidence is solid, its interpretation in terms of evolutionary responses to shared predators (visual signals) and avoiding between-species mating (chemical signals) is overstated due to the lack of direct experimental evidence.

eLife Assessment

This study presents a valuable advance for the analysis of gene expression variation at the level of individual cells by introducing a novel reference-free framework that can detect splicing, fusion, editing, immune-receptor diversity and repeated elements in sequencing data. The evidence supporting these claims is solid, with rigorous validation on simulated datasets and extensive analysis of full-length single-cell sequencing data demonstrating improved performance over existing methods. This work will be of particular interest to researchers developing methods for high-resolution transcriptome analysis and to those studying cellular heterogeneity in health and disease.

eLife Assessment

This important study applies an innovative multi-model strategy to implicate the ribosomal protein (RP) encoding genes as candidates causing Hypoplastic Left Heart Syndrome. The evidence from the screen in stem cell-derived cardiomyocytes and whole genome sequencing of human patients, followed by functional analyses of RP genes in fly and fish models, is convincing and supports the authors' claims. This work and methodology applied would be of broad interest to medical biologists working on congenital heart diseases.

eLife Assessment

This study presents an important finding on the role of GATA4 in aging and OA-associated cartilage pathology. The evidence supporting the conclusions is compelling, with rigorous in vitro and in vivo data. The work will be of broad interest to cell biologists and orthopedic clinicians.

eLife Assessment

This important study investigated whether the nuclear receptor Nur77 is regulated by a non-canonical mechanism of ligand-induced disruption of its interaction with RXRg, similar to the family member Nurr1. The overall evidence is solid, but additional mechanisms that have not been fully explored in this study might contribute as well. This manuscript will be of interest to scientists focusing on mechanisms of transcriptional regulation.

eLife Assessment

This study clarifies that stalled RNA pol II is not sufficient for AID targeting, which is important to the field. The authors provide solid experimental evidence that RNA poll II stalling is not the driving mechanism for AID targeting, and even though the results are generally "negative", they are highly relevant to our current understanding of SHM. The authors propose premature transcription termination as a possible mechanism to determine V gene mutability, but the study does not experimentally address such possibilities. This paper makes investigators rethink the model with which AID finds single-strand DNA in the genome.

eLife Assessment

This useful study presents a biologically realistic, large-scale cortical model of the rat's non-barrel somatosensory cortex, investigating synaptic plasticity of excitatory connections under varying patterns of external activations and characterizing relations between network architecture and plasticity outcomes. The model offers an impressive level of biological detail, addressing many aspects of the cellular and network anatomy and properties, and investigating their relationships to the biologically plausible plasticity. The numerical simulations appear to be well executed and documented, providing an excellent resource to the community. The evidence supporting the main conclusions is solid with results being more observational in nature, and minor weaknesses relating to the lack of explanatory power of causal relationships and mechanisms.

eLife Assessment

This study presents a valuable description of the cellular and transcriptional landscape of the tumor microenvironment in 27 gastric cancer (GC) patients based on their H. pylori status (HpGC, ex-HpGC, non-HpGC). The single-cell RNA sequencing dataset and computational analysis are convincing and provide a starting point that is of value for understanding H pylori-associated GC cell type composition, cell transitions, and mechanisms of response to therapy. The section correlating immunotherapy outcomes with GC cell type compositions from bulk RNAseq would have been strengthened by further comparing H. pylori GC versus non H. pylori GC.

eLife Assessment

This manuscript provides valuable mechanistic insight into NSCLC progression, both in terms of tumour metastasis and the development of chemoresistance. The authors draw upon a range of techniques and assays and the evidence shown is solid and has been strengthened by incorporation of suggestions by the two reviewers. The work presented will be of interest to cancer biologists and more broadly to those interested in NSCLC translational studies.

eLife Assessment

This study presents fundamental findings that could redefine the specificity and mechanism of action of the well-studied Ser/Thr kinase IKK2 (a subunit of inhibitor of nuclear factor kappa-B kinase (IkB) that propagates cellular response to inflammation). Solid evidence supports the claim that IKK2 exhibits dual specificity that allows tyrosine autophosphorylation and the authors further show that auto-phosphorylated IKK2 is involved in an unanticipated relay mechanism that transfers phosphate from an IKK2 tyrosine onto the IkBa substrate. The findings are a starting point for follow-up studies to confirm the unexpected mechanism and further pursue functional significance.

eLife Assessment

This manuscript addresses the role of alpha oscillations in sensory gain control. The authors use an attention-cuing task in an initial EEG study followed by a separate MEG replication study to demonstrate that whilst (occipital) alpha oscillations are increased when anticipating an auditory target, so is visual responsiveness as assessed with frequency tagging. The authors propose that their results demonstrate a general vigilance effect on sensory processing and offer a re-interpretation of the inhibitory role of the alpha rhythm. While some concerns remain about the interpretation of the alpha inhibition hypothesis, these results are valuable, and the provided evidence is solid.

eLife Assessment

In this work, the authors characterize the synaptic adhesion molecule RTN4RL2, demonstrating its critical involvement in the development and function of auditory synapses between inner hair cells and spiral ganglion neurons. This study is important because it offers potential insights into therapeutic strategies for hearing loss associated with synaptic dysfunction. The findings are solid, because they are supported by the use of multiple advanced techniques, including FISH and SBEM imaging.

eLife Assessment

This study provides an important contribution to our understanding of the mechanisms underlying the limited capacity to process rapid sequences of visual stimuli. It reports convincing evidence that the attentional blink affects neurally separable processes of visual detection and discrimination. The study will be of interest to neuroscientists and psychologists investigating perception and attention.

eLife Assessment

Using several hundreds of samples and cutting-edge genomic methods, including BioNano, PacBio, HiFi, and advanced bioinformatic pipelines, the authors identify six large chromosomal inversions segregating in over 100 species of Lake Malawi cichlids. This important study provides compelling evidence for the presence of these six inversions, their differential distribution among populations, and the association of chromosome 10 inversion with a sex-determination locus. This work also provides a starting point for further investigating the role of these inversions with respect to local adaptation, speciation, sex determination, hybridization, and ILS in cichlids, which represent ~5% of the extant vertebrate species and are one of the most prominent examples of adaptive radiations.

eLife Assessment

This study presents a useful characterisation of the topographical organisation of the human pulvinar, an associative thalamic subregion crucial for visual perception and attention. The evidence supporting the conclusions is solid given the multimodal validation and replication across datasets, although even higher-resolution imaging data would have strengthened the study. In their revised manuscript, the authors elaborated further on the motivation for their study and conducted several robustness checks. Nevertheless, there remains an opportunity for a more fully integrated interpretation of the findings. The work would be of interest to neuroscientists, neurologists, and neuropsychiatrists working on pulvinar functioning in health and disease.

eLife Assessment

This useful study describes expression profiling by scRNA-seq of thousands of cells of recombinant yeast genotypes from a system that models natural genetic variation. The rigorous new method presented here shows promise for improving the efficiency of genotype-to-phenotype mapping in yeast, providing convincing evidence for its efficacy. This manuscript focuses on overcoming technical challenges with this approach and identifies several new biological insights that build upon the field of genotype-to-phenotype mapping, a central question of interest to geneticists and evolutionary biologists.

eLife Assessment

This paper presents a valuable software package, named "Virtual Brain Inference" (VBI), that enables faster and more efficient inference of parameters in dynamical system models of whole-brain activity, grounded in artificial network networks for Bayesian statistical inference. The authors have provided solid evidence, across several case studies, for the utility and validity of the methods using simulated data from several commonly used models, but more thorough benchmarking could be used to demonstrate the reliability, generalizability, and practical utility of the toolkit. This work will be of interest to computational neuroscientists interested in modelling large-scale brain dynamics.

eLife Assessment

This study presents valuable findings on the patterned loss of Purkinje cells in the mouse cerebellum during aging. Convincing evidence shows that Purkinje cell loss with aging occurs in a pattern of parasagittal stripes in relationship with the zebrin-II expression pattern. Further evidence supporting the Purkinje cell aging loss pattern as it relates to human cerebellar aging would strengthen the study.

eLife Assessment

This study presents a valuable finding on how the locus coeruleus modulates the involvement of medial prefrontal cortex in set shifting using calcium imaging. The evidence supporting the claims was viewed as incomplete, although a more rigorous statistical comparison of intradimensional vs. extradimensional stages of the task, either in behavior or in the calcium imaging data, would help to address this concern. The work is of broad interest to those studying flexible cognition.

eLife Assessment

This valuable study found Gamma Knife SBRT combined with tislelizumab offers a safe and powerful later-line option for pMMR/MSS/MSI-L metastatic CRC patients who were unresponsive to the first and second-line chemotherapy. The authors implemented a well-structured experimental protocol and provide convincing evidence to substantiate the conclusions. This work would be of broad interest to oncologists working on colorectal cancer.

Evaluation Statement (30 January 2025)

Kay and Aminzare discuss a claim made in a prior publication that macromolecular condensation acts as a water buffering mechanism in cells to compensate for the effects of osmotic shock. The authors argue that, although such a buffer could temporarily maintain a transmembrane osmolality differential, this differential would drive water across the membrane to reach a steady-state in which osmolality within the cell equals osmolality outside the cell. Using the well-established pump-leak model for osmotic water transport, they further show that the timescale at which a water buffer could maintain a modest 10% osmolality differential across the membrane is at most one minute for a typical animal cell.

Biophysics Colab recommends this study to researchers working on membrane transport, intracellular water buffering, and condensate biology.

Biophysics Colab has evaluated this study as one that meets the following criteria:

• Rigorous methodology
• Transparent reporting
• Appropriate interpretation

eLife Assessment

This study provides important information on the ultrastructural organization of layer 1 of the human neocortex. The quantitative assessment of various synaptic parameters, astrocytic coverage and mitochondrial morphology is based on convincing experimental approaches. These data provide new information on the detailed morphology of human neocortical tissue that will be of interest to neuroscientists working on different network functions.

eLife Assessment

In this valuable study, the authors report on an innovative chemostat propagation system to reduce eukaryotic viruses while retaining phages in mixtures used for FVTs (fecal virome transplant). The authors hypothesized that chemostat-propagated viromes could modulate the gut microbiota and reduce necrotizing enterocolitis (NEC) lesions while avoiding potential side effects, such as earlier onset of diarrhea. The study is solid in that it integrates in vitro fermentation, high-resolution metagenomics, immunogenicity assays, and in vivo validation, demonstrating the potential of FVT using eukaryotic-free virome-based therapeutics. However, the study overall has some conceptual and technical limitations.

eLife Assessment

Mackie and colleagues present a valuable comparison of lateralized gustation in two well-studied nematodes. Their results present convincing evidence that ASEL/R lateralization exists and is achieved by different means in P. pacificus compared to C. elegans. This work will be of interest to neurobiologists interested in how small nervous systems make sense of the environment, and how evolution can take multiple paths to asymmetry within a neuron class.

eLife Assessment

This study provides an important and timely analysis of invasive and non-invasive Streptococcus pyogenes emm89 isolates, which have become a dominant serotype in the past decade. Using genome sequencing of 311 strains from Japan and comparing them with 666 global strains, the authors present compelling evidence in support of the identification of genetic factors linked to the invasive phenotype of emm89. The findings are both theoretically and practically significant in medical microbiology.

eLife Assessment

This valuable study presents a deep learning framework for predicting synergistic drug combinations for cancer treatment in the AstraZeneca-Sanger (AZS) DREAM Challenge dataset. The level of evidence seems solid, although performance on some datasets seems unconvincing and further validation would be required to demonstrate the generalizability of the model and, in turn, its clinical relevance. The reported tool, DIPx, could be of use for personalized drug synergy prediction and exploring the activated pathways related to the effects of drug combinations.

eLife Assessment

This is valuable work with theoretical implications for possible mediation by MMP12 in the link between atherosclerosis and intracranial aneurysms, using Mendelian Randomization for causal inference. Additional analysis would be required to verify the claims, which currently have incomplete support in terms of the strength of evidence. Given that most of the identified causal associations do not hold after correcting for multiple tests, the conclusions should be carefully reviewed in order to be fully supported by the results.

eLife Assessment

The reported cryo-EM imaging of a pentameric ligand-gated ion channel in liposomes as opposed to nanodiscs has both broad implications and contributes valuable methodological advances to the structural investigation of membrane receptors. The comparison of structures assigned to distinct functional states in liposomes versus nanodiscs is convincing, and will aid membrane protein structural biologists in selection of functionally relevant membrane reconstitution environments. This work could be strengthened by a more quantitative presentation of the pore dimension profile leading to the proposed 9' desensitization gate with discussion of the additional apparent constriction at 2' in the desensitized structure, and by a more thorough description of the biochemistry methods for which core parts are not described and/or discussed in sufficient detail.

eLife Assessment

This valuable study highlights the potential of combining immunotherapy for pMMR CRC by selecting suitable cases and demonstrating that Gamma Knife SBRT with tislelizumab provides a safe and effective later-line treatment option for patients with pMMR/MSS/MSI-L mCRC unresponsive to standard chemotherapy. The authors employed a robust experimental design and rigorous statistical analyses to ensure the reliability of their findings. Their results offer convincing evidence to support the clinical value of this combined therapeutic approach.

eLife Assessment

This important work supports the role of breast carcinoma amplified sequence 2 (Bcas2) in positively regulating primitive wave hematopoiesis through amplification of beta-catenin-dependent (canonical) Wnt signaling. The study is convincing: it uses appropriate and validated methodology in line with the current state-of-the-art, and there is a first-rate analysis of a strong phenotype with highly supportive mechanistic data. The findings shed light on the controversial question of whether, when, and how canonical Wnt signaling may be involved in hematopoietic development. The work will be of interest to hematologists and developmental biologists.

eLife Assessment

How misfolded proteins are segregated and cleared is a significant question in cell biology, since clearance of these aggregates can protect against pathologies that may otherwise arise. The authors discover a cell cycle stage-dependent clearing mechanism that involves the ER chaperone BiP, the proteosome, and CDK inactivation, but is curiously independent of the anaphase promoting complex (APC). These are valuable and interesting new observations, and the evidence supporting these claims is solid.

eLife Assessment

This useful study uses brain stimulation and electroencephalography to study speech-gesture integration. It investigates the role of frontotemporal regions in integrating linguistic and extra-linguistic information during communication, focusing on the inferior frontal gyrus and posterior middle temporal gyrus. Reliance on activation patterns of tightly-coupled brain regions over short timescales leads to incomplete support for the study's conclusions due to conceptual and methodological limitations.

eLife Assessment

The study presents a fundamental advance in antiviral RNA research by adapting SHAPE-Map to chart the secondary structure of the Porcine Epidemic Diarrhoea Virus (PEDV) genome in infected cells and pinpointing structurally conserved, accessible RNA elements as therapeutic targets. A broad, well-documented integration of biochemical probing, computational analysis, and functional validation provides convincing evidence that these regions are both biologically relevant and druggable. Beyond PEDV, the work offers a generalizable framework for RNA-guided antiviral discovery that will interest researchers in RNA therapeutics and viral genome biology.

eLife Assessment

This paper presents valuable findings on the processing of sound mixtures in the auditory cortex of ferrets, a species widely used for studies of auditory processing. Using the convenient and relatively high-resolution method of functional ultrasound imaging, the authors provide solid evidence that background noise invariance emerges across the auditory cortical processing hierarchy. However, differences between this and other methods limit the comparisons that can be made across different species, and additional controls are needed to fully substantiate the paper's claims. This work will nonetheless be of interest to researchers studying the auditory cortex and the neural mechanisms underlying auditory scene analysis and hearing in noise.

eLife Assessment

This work presents an important genetic toolkit for Drosophila neurobiologists to access and manipulate neuronal lineages during development and adulthood. The evidence supporting the fidelity of this toolkit after revision is compelling. This work will interest Drosophila neurobiologists in general, and some of the genetic tools may be used outside the nervous system. The conceptual approaches used in this paper are likely transferable to other fields as comparable data and genomic methods are obtained.

eLife Assessment

Oor and colleagues report the potentially independent effects of the spatial and feature-based selection history on visuomotor choices. They outline compelling evidence, tracking the dynamic history effects based on their extremely clever experimental design (urgent version of the search task). Their finding is of fundamental significance, broadening the framework to identify variables contributing to choice behavior and their neural correlates in future studies.

eLife Assessment

This is a well-written important paper on the recovery of fauna and flora following the end-Permian extinction event in several continental sites in northern China. The convincing conclusion, a rapid recovery in tropical riparian ecosystems following a short phase of hostile environments and depauperate biota, is supported by an impressive amount of data from sedimentology, body fossils of animals and plants, and especially trace fossils.
