eLife Assessment

In this study, Yuan and colleagues perform transcriptomic and epigenomic experiments to study open chromatin regions and transcripts that change upon larval settlement in the sponge Amphimedon. The authors present compelling evidence to show that sponge larvae prepare for receiving an environmental cue (sunset) by extensively modifying their chromatin accessibility in the vicinity of genes that are going to be regulated during metamorphosis. The study represents a fundamental advance in understanding the fine genetic control of larval settlement and has significance beyond the immediate field of sponge larval biology.

The study presents important findings revealing previously unresolved conformational dynamics of the heterodimeric type IV ABC transporter TmrAB using single-molecule FRET. The evidence presented is solid, integrating careful experimental design with computational approaches to uncover states that are typically masked and difficult to detect. The work will be of interest to scientists studying the molecular mechanisms of primary active transport processes.

eLife Assessment

This large-scale comparative study of odorant receptor (OR) genes across more than 100 insect species, combining sequence- and structure-based approaches, aims to explore the evolution of this large gene family involved in the detection of odorant signals by olfactory neurons. This useful work uncovers a structural feature unique to the odorant receptor co-receptor Orco that reduces ligand binding affinity. However, the strength of evidence is incomplete: the pipeline for in silico identification of odorant receptor genes lacks validation through comparison with known odorant receptor repertoires from previously studied species, and claims regarding odor response spectra, evolutionary, and ecological interpretations are not fully supported by the analyses.

eLife Assessment

The study presents useful findings on the behavioral effects of nicotine exposure, suggesting the Drosophila larva as a potential model organism for studying underlying neural circuits. However, the evidence supporting the claims of the authors is incomplete and would benefit from more rigorous analysis and explanations. The study falls short of identifying the neural mechanisms and is therefore of interest to those with an interest in pharmacology and behavior.

This manuscript examines the evolution of molluscan shells using single-cell analyses of the adult mantle of Crassostrea gigas and compares these data with previous datasets from embryonic and larval stages of this species and other spiralians. The authors provide important support for a scenario in which secretory cells are broadly conserved across spiralians, and the incorporation of lineage-restricted genes contributes to the evolution of molluscan shells. While some of the conclusions of the authors are convincing, many aspects of the manuscript remain incomplete and could be improved, especially aspects of cell-type classification and validation.

eLife Assessment

This study presents a valuable perspective on platelet-mediated fibrin compaction, proposing that fibrin fibers undergo "winding" or coiling, an intriguing framework with potential implications for thrombosis and clot mechanics. However, the evidence supporting an active platelet-driven winding mechanism remains incomplete, relying largely on correlative observations without direct or quantitative validation of the proposed dynamics. Overall, the work is thought-provoking and of clear interest to the field, but stronger mechanistic evidence will be required to substantiate the central claims.

This study introduces the "Training Village," a valuable system for which solid evidence shows that it enables group-housed rodents to autonomously learn complex tasks while preserving natural social interactions. The platform is flexible, allowing animals to learn multiple tasks sequentially and supporting applications in continual learning. This approach is likely to be of broad interest to behavioral researchers using rodent models in systems and cognitive neuroscience.

This fundamental work significantly advances our understanding of the circuit-level implementation of predictive processing by elucidating the functional influence between putative prediction error neurons in layer 2/3 and putative internal representation neurons in layer 5. The evidence demonstrating that neither the hierarchical nor the non-hierarchical variant of predictive processing fully accounts for the presented data is convincing. Moving forward, this line of work would benefit from explicitly comparing different theories, thereby clearly articulating the points raised in this paper.

eLife Assessment

This study provides a valuable contribution to our understanding of the neural basis of perceptual decision-making by jointly modeling behavioral outcomes and EEG signals in a contrast comparison task. The methods and analyses are solid, systematically comparing standard models assuming continuous evidence accumulation with models that track evidence without temporal integration (extrema detection). The authors show that behavior and neural signals are equally consistent with both alternatives, highlighting limitations in current modeling approaches and questioning the generality of evidence accumulation mechanisms.

eLife Assessment

This valuable study explores changes in the Drosophila microbiome in response to environmental temperature over more than ten years. The evidence showing that temperature leads to diversification of bacterial clades is solid, but additional information would help clarify how subspecies competition impacts microbiome composition and the host. The work will interest researchers working with microbiomes, microbial ecology, and evolutionary biology.

eLife Assessment

This manuscript addresses an important question in clinical neuroscience: the use of the theta/beta ratio as a biomarker of attention deficit hyperactivity disorder (ADHD). The study takes an exceptional "multiverse" analysis approach to show that aperiodic activity differences between healthy controls and people with ADHD are driving the apparent theta/beta ratio differences. From a neuroscientific perspective, this is a critical finding because it has a major impact on guiding research on the diagnosis and treatment of ADHD.

eLife Assessment

This valuable study presents a comprehensive comparison of human and macaque monkey behavior across a range of visual perceptual phenomena. The use of a unified oddball visual search paradigm enables direct cross-species comparison while minimizing task-related confounds. It provides solid evidence that visual perception is largely similar between these two species, with some interesting exceptions. These insights into qualitative and quantitative differences between species are relevant for evaluating macaques as a model organism for understanding human vision.

eLife Assessment

This valuable study examined the geometry of visual object representations across hierarchically organized stages of the mouse visual cortex. The use of large-scale training and recording techniques provides solid evidence for changes along the hierarchy that may contribute to invariant object recognition. These findings, particularly if they could be supported by further analyses and clarifications to rule out alternative explanations, including influences of low-level features on behavior and neural activity, help establish the potential usefulness of the mouse to understand the neural basis of object recognition.

eLife Assessment

This important study shows that action potentials undergo frequency-dependent failure along the axons of fast-spiking interneurons during sustained high-frequency firing, offering a mechanistic explanation for why inhibition may fail to restrain seizures. The evidence is solid, though additional analyses could further strengthen the mechanistic interpretation. The work will be of broad interest to neuroscientists studying axonal physiology, cortical inhibition, and epilepsy.

eLife Assessment

This important study by Kong et al. systematically and rigorously dissects the gene regulatory network underlying melanoma and breast cancer risk at the multi-cancer 2q33 locus. The authors provide compelling evidence that rs3769823 is a key functional variant that acts through allele-preferential binding of the transcription factors E4F1 and IRF2 to regulate CASP8 and FLACC1 in a cell-type-specific manner. The work makes a significant contribution to understanding the mechanisms operating at multi-cancer risk loci.

eLife Assessment

This valuable study contributes to the field of neuro-glial biology by establishing a direct causal link between astrocytic metabolism (glycolysis) and the structural wiring of neural circuits. Connecting the metabolic-synaptic mechanism to locomotor reorientation in the dopaminergic circuit offers new insights into how energy metabolism shapes circuit assembly and function. The evidence offers a solid foundation, moving logically from molecular mechanisms to circuit-level anatomy and finally to behavior; however, several central conclusions currently exceed the direct evidence presented. With appropriate calibration of claims and interpretations and/or additional clarifying experiments, the manuscript has the potential to make a significant contribution to our understanding of glial regulation of circuit assembly.

eLife Assessment

This is a valuable study on single-cell transcriptomic analyses, focused on morphogenesis of the zebrafish inner ear in wildtype and lmx1bb mutants. The supporting evidence is mostly convincing, but incomplete in parts.

eLife Assessment

In this important manuscript, Matsuda and colleagues present a model describing the regulation of tracheal tubulogenesis in Drosophila melanogaster embryos. The authors support this model using convincing approaches that combine novel experimental results with previously published work from their group. While some conclusions are consistent with earlier studies, the present manuscript introduces distinct molecular markers not previously reported, which reinforce the authors' prior findings. In addition, the manuscript analyses, using experimental strategies, the requirement of the Dpp and EGFR signalling pathways for the maintenance of trachealess (trh), one of the key transcription factors governing tracheal development.

eLife Assessment

This manuscript provides valuable high-resolution structural insights into the interaction between vaccine-elicited antibodies and SARS‑CoV‑2 evolution. The evidence is solid; however, the conclusions could be strengthened with further experimentation and analysis.
