This important work advances our understanding of NMDAR diversity in the brain by providing evidence into the subunit arrangement, architecture, and activation mechanism of GluN1-N2-N3A tri-NMDAR. However, the evidence supporting the conclusions provides incomplete proof for the presence and functional properties of this NMDA receptor subtype. The work will be of broad interest to neuroscientists and biophysicists.

eLife Assessment

This important study provides solid evidence that early childhood malaria exposure affects the development of antibody responses to unrelated pathogens and vaccine-derived antigens in Kenyan children. The findings are of major public health importance and limitations of the observational study design are properly acknowledged.

eLife Assessment

This valuable study uses a sophisticated array of techniques to investigate the mechanisms through which the chordotonal receptors in the locust ear (Müller's organ) sense auditory signals. Ultrastructural reconstruction of the sensory organ provides convincing evidence of the organization of the scolopidial structure that wraps the sensory neuron cilium. However, the recordings of sound-evoked motion and electrophysiological activity from the chordotonal sensory neurons provide incomplete evidence for the proposed axial stretch model of mechanotransduction.

eLife Assessment

Using high-throughput small-molecule screening, this study discloses novel modulators of the mitochondrial transcription factor A (TFAM), a key regulator of mitochondrial function. Reviewers viewed the targeting of TFAM as innovative and the study's conclusions as potentially important (especially the effects on inflammation). However, the lack of evidence for a direct effect of the compounds on TFAM activity weakens the paper's key conclusion and renders the study incomplete.

eLife Assessment

This important manuscript presents the Crunchometer, an open-source and low-cost acoustic system for high-resolution quantification of biting and chewing in mice. The work addresses a need for reliable measures of food consumption and feeding microstructure, and the tool has broad relevance for studies of ingestive behavior, appetite circuits, hypothalamic function, and pharmacological interventions. The evidence supporting the methodological advance is convincing, and the Crunchometer outputs were carefully validated against human observer scoring, reliably distinguished biting and chewing events, and captured changes in feeding behavior across different foods, physiological states, and semaglutide treatment. The study also demonstrates that the system can reveal biologically meaningful features of feeding, including meal structure, bite and chew dynamics, and altered consumption patterns after pharmacological manipulation. A significant additional contribution is the identification of previously unrecognized meal-related neurons in the lateral hypothalamus, providing novel circuit-level insight into solid food consumption and naturalistic feeding behavior. Although some neuroscience conclusions remain more preliminary than the methodological validation, the study provides strong evidence for the utility of the Crunchometer and will be of interest to researchers studying ingestive behavior, hypothalamic circuits, and metabolic regulation.

eLife Assessment

This study presents a useful inventory of genes that are up- and down-regulated in the mouse small intestine (duodenum and ileum) during the first postnatal month; the data were collected and analyzed using solid and validated methodology and can be used as a starting point for additional validation of specific markers and for follow-up functional studies. Some aspects of the study were incomplete, with claims being only partially supported by the data, and it is suggested that additional validation be performed. The authors attempted to correlate gene expression changes with periods of high and low NEC susceptibility, but these correlations are speculative and not supported by functional follow-up studies. Discussion of gene expression changes with NEC susceptibility would be more appropriate to include in the Discussion section and to be tempered in the results section.

eLife Assessment

This valuable study examined the roles of the posterior parietal cortex in rats performing an auditory change-detection decision task. It provided solid evidence for two subpopulations with opposing modulation patterns during decision formation and for a correspondence between neural and behavioral measures of the short timescale used for evidence evaluation.

eLife Assessment

This is a valuable study that integrates behavioral and molecular approaches to identify neuromodulators influencing blood-feeding behavior in the disease vector Anopheles stephensi. Through gene expression analyses across blood-seeking life stages and RNA interference experiments, the authors present solid evidence that co-knockdown of the neuromodulators short Neuropeptide F and RYamide affects blood-seeking states in A. stephensi. However, evidence demonstrating that these neuropeptides are sufficient to promote host-seeking is lacking.

eLife Assessment

This manuscript investigates inter-hemispheric interactions in the olfactory system of Xenopus tadpoles. Using a combination of electrophysiology, pharmacology, imaging, and uncaging, the transection of the contralateral nerve is shown to lead to larger odor responses in the un-manipulated hemisphere, and implicates dopamine signaling, likely originating from the lateral pallium, in this process. The study convincingly uses a rich and sophisticated array of tools to investigate olfactory coding, and uncovers valuable mechanisms of signaling likely to be conserved across vertebrates.

eLife Assessment

This valuable developmental study provides intriguing but incomplete evidence suggesting that, relative to adults, the enhancement of instrumental learning by Pavlovian bias is most pronounced in adolescence, while reward-induced memory enhancements are strongest in childhood. Although the authors tackle a key aspect of learning and motivation with rigorous experimental methods and sophisticated modeling techniques, there are substantial concerns about the absence of relevant analyses, the lack of accord between model-based and exploratory analyses, and the lack of an explanation for how the results cohere with inconsistent findings in the literature.

eLife Assessment

This study provides a valuable contribution to understanding the functional and molecular organization of the medial nucleus accumbens shell in feeding behavior. Through a multimodal approach that integrates in vivo imaging, optogenetic manipulation, and genetic strategies, the authors present convincing evidence for rostro-caudal differences in D1-SPN activity, advancing and refining earlier pharmacological frameworks. The discovery of Stard5 and Peg10 as regionally informative markers, together with the introduction of a Stard5-Flp driver line, establishes a foundation for more targeted circuit dissection. While an expanded characterization of other Stard5-positive cell populations (e.g., D2-SPNs, interneurons) would strengthen the work, the experimental rigor and internal consistency of the findings are clear. Overall, this is a technically strong and conceptually meaningful study with broad relevance for those investigating neural mechanisms of reward, affect, and feeding.

eLife Assessment

This study presents a valuable in-depth comparison of statistical methods for the analysis of ecological time series data, and shows that different analyses can generate different conclusions, emphasizing the importance of carefully choosing methods and of reporting methodological details. The evidence supporting the claims, based on simulated data for a two-species ecosystem, is solid, although testing on more complex datasets could be of further benefit. This paper should be of broad interest to researchers in ecology.

eLife Assessment

This is an important study of critical period plasticity, focused on temperature manipulations, and how different parts of the Drosophila larval motor circuit adapt or maladapt. The work convincingly demonstrates that components of the motor network respond in distinct ways to the heat shock, and the combination of functional, structural, and electrophysiological approaches makes the study of significant interest. The work points to central interneurons as primary drivers of maladaptive changes, while motoneurons and neuromuscular junctions show compensatory or homeostatic adjustments. The study is methodologically rigorous, contributing significant insights into critical period biology using a tractable invertebrate model.

eLife Assessment

This important work combines theoretical analysis with precise experimental perturbation to demonstrate a previously unappreciated quantitative characteristic of the Wnt signaling pathway, which is anti-resonance, or a suppression of pathway output at intermediate activation frequencies. This effect is demonstrated experimentally with compelling evidence from optogenetic stimulation in multiple cell types, alongside modeling results that corroborate the phenomenon. While the demonstration of this phenomenon has yet to be extended to fully physiological situations, its clear existence within optogenetically stimulated systems shows that it is likely a significant factor that contributes to the behavior of this central signaling pathway.

eLife Assessment

This important work employed a recent functional muscle network analysis to evaluate rehabilitation outcomes in post-stroke patients. The research direction is relevant and supported by solid evidence from gross motor function assessment. The framework is a step toward standardized assessment of motor recovery in the rehabilitation process, but future studies would focus on linking functional recovery to muscle interaction biomarkers to provide more physiologically grounded interpretations.

eLife Assessment

This valuable study is a comprehensive investigation into the regulatory mechanisms and regional distribution of enteroendocrine cell subtypes in the Drosophila midgut, significantly advancing the understanding of how WNT and BMP gradients contribute to EE diversity. The methodological foundation and robust genetic evidence are solid in supporting the key roles of compartment boundary signals, particularly WNT and BMP, in specifying EE subtypes and division modes. However, there is a lack of full mechanistic insight regarding Notch pathway involvement, incomplete quantification of phenotype data, and insufficient global pattern analysis, which detracts from fully supporting some proposed models. Overall, the study provides a platform for future work but would benefit from stronger data integration and expanded mechanistic exploration.

eLife Assessment

This valuable study addresses the effects of selection on aggression on fitness and life-history trade-offs in Drosophila melanogaster. However, the evidence presented is incomplete and does not support the claims proposed in the study of increased survival of highly aggressive males at the expense of reproductive success and shorter mating duration. The main limitation of the study is the choice to use males from only one aggressive Drosophila line in combination with CantonS females, that do not allow disambiguation between nonaggression-related factors, such as hybrid vigor and aggression-related factors influencing mating and lifespan.

eLife Assessment

This valuable study examines how mammals descend effectively and securely along vertical substrates. The conclusions from comparative analyses based on behavioral data and morphological measurements collected from 21 species across a wide range of taxa are convincing, making the work of interest to all biologists studying animal locomotion.
