In this manuscript, the authors describe a cell-specific mechanism by which glutamate transporters regulate the fidelity with which T-stellate cells in the mouse ventral cochlear nucleus relay information from auditory nerve inputs. The study is supported by solid electrophysiological data. It provides valuable insights into how the rapid binding of glutamate to transporters shapes auditory information processing at specific synapses.

This manuscript describes an important development of several variants of optogenetic tools to control endogenous p53 activity. They are based on peptides competing with Mdm2/MdmX for binding to p53, thus releasing p53 from its negative regulators and stabilizing its cellular levels. In principle, the data are convincing but should be complemented by investigations of p53 target genes at endogenous levels (instead of only reporter constructs). The study therefore remains incomplete but will be of interest to scientists working on optogenetics as well as the p53 field.

Verma and colleagues interrogate the mechanisms of phagosome maturation arrest during Mycobacterium tuberculosis infection. While cellular events that culminate in this arrest have been largely elucidated, involvement of other organelles, such as mitochondria, has not been highlighted mechanistically. In this valuable study, elements of mitochondrial quality control, such as mitophagy and mitochondrial-derived vesicles involvement, are shown to be paramount in the host-pathogen tussle. The evidence supporting the main conclusions is solid, based on multiple complementary approaches and appropriate controls, although some central mechanistic aspects of the proposed pathway remain only partially resolved.

This study investigates the cellular mechanisms underlying theta-nested gamma oscillations in the medial entorhinal cortex; the experiments are rigorous, and the analyses and modeling provide potentially useful insights into cell-type-dependent circuit dynamics. However, the evidence supporting several key conclusions remains incomplete. The study is limited by conceptual constraints in the experimental design and a modeling approach that does not fully address underlying physiological mechanisms. Overall, this is a careful study that addresses how distinct neuronal populations in superficial MEC participate in theta-gamma coordination and provides new data linking cell-type-specific activity patterns to oscillatory network structure.

In this useful Tools & Resources article, the authors describe a new cryogenic light microscopy design and characterize its temperature and spatial stability. This compelling system avoids the challenges associated with vacuum-based designs, particularly vacuum transfer systems, which are difficult to engineer. A key advantage of the system is that it reduces ice contamination and drift, which are the primary challenges in open cryostat systems.

This study presents an important large-scale behavioral and transcriptomic analysis of Drosophila that are heterozygous for putative loss-of-function alleles of homologs of human genes that have been linked to autism spectrum disorders. The authors consider 48 genes as hits from their screen, which show significant behavioral alterations in sleep, basal activity, and/or social behavior, and significant sexual dimorphism. The authors then focus on the domino/SRCAP gene as a candidate regulator of sleep, social behavior, transcriptional programs, and RNA splicing. The work generates a solid dataset and applies quantitative analytical approaches that will be of interest to researchers in the field, yet the evidence presented remains incomplete because issues of genetic background need to be further addressed.

eLife Assessment

This manuscript describes a valuable study of the mechanism by which acetylation on the histone H3 core domain regulates RNA polymerase II transcription passing through nucleosomes. The authors provide convincing evidence that acetylation influences transcription in a context-specific fashion. Some questions relating to the static nucleosome structures and the polymerase passage remain, but this manuscript will be of considerable interest to researchers in the chromatin and transcription fields.

eLife Assessment

This important study provides a mechanistic view of how antibody affinity maturation can reshape encounter-state landscapes and association pathways, with implications for understanding HIV antibody maturation and vaccine design. The results are solid, supported by a coherent integration of adaptive molecular dynamics, Markov state modeling, SPR kinetics, mutagenesis, and double-mutant cycle analysis, although aspects of the kinetic validation, MSM-state robustness, and causal interpretation would benefit from further support. The work will be of interest to immunologists, structural biologists, and computational biophysicists.

This valuable study introduces MULTI i², a robust and high-throughput method to measure Plasmodium falciparum viability in the presence of drugs. This new assay offers significant time savings over the traditional Parasite Reduction Rate (PRR) assay and should enable faster screening of drug combinations, which is urgently needed in the field. The assay is well validated, with convincing data showing it can reproduce known drug interactions and identify new interaction patterns.

eLife Assessment

This study makes a solid and valuable contribution to elucidating the intricate relationship between mitochondrial calcium and neuronal survival. Well-controlled experiments show that homeostatic mitochondrial calcium correlates with the most resilient neuronal subtypes after optic nerve injury. However, altering mitochondrial calcium levels does not affect neuronal survival as initially predicted by this correlation.

eLife Assessment

This study presents a key finding: self-generated mechanical stresses enable collective protocell proliferation without dedicated division machinery, offering insight into primitive life's population growth. While quantitative imaging, membrane tension measurements, and computational modeling support the mechanism, establishing causal links between deformation and division and testing sensitivity assumptions would strengthen the work. Overall, the work reports important findings, and although the evidence in support of the conclusions is largely solid, some incomplete elements need to be addressed.

eLife Assessment

This important study combines experimental evidence with computational modeling to suggest that neurons in the frontal eye field form two overlapping topographical maps, one for visual inputs and the other for eye movement directions. The experiments leverage the smooth cortex of the marmoset to provide solid evidence that two maps exist at different scales. The modelling work provides a potential mechanistic insight into how these patterns may be used for flexible visuomotor transformations.

eLife Assessment

By mining the Logan assemblage of the Sequence Read Archive to reveal substantial papillomavirus diversity, this valuable study establishes a framework for integrating viral discovery with host, geographic, and ecological metadata. The evidence for identifying novel papillomavirus sequences is convincing, supported by large-scale sequence searches, established L1-based typing criteria, phylogenetic analyses, protein annotation, and structural comparisons. The broader host-association and ecological conclusions are more tenuous due to heterogeneous public metadata and uneven sampling, and would benefit from clearer discussion of potential biases, contamination, endogenous viral elements, and alternative explanations. The work should be of interest to a broad range of colleagues in the areas of microbiome research, virology, and viral evolution.

eLife Assessment

This important study addresses a timely issue at the intersection of mitochondrial and telomere biology by focusing on the relationship between naturally occurring variants in the mitochondrial genome and telomere length. This work thereby provides a conceptual and experimental framework for investigating communication between mitochondria and telomeres. Using an innovative transmitochondrial cybrid approach, the authors provide evidence that mitochondrial DNA variants influence telomere maintenance through effects on mitochondrial function, reactive oxygen species, and NAD⁺-dependent repair processes. The evidence supporting the central conclusion that mitochondrial genotype influences telomere-associated phenotypes is convincing and is strengthened by the use of complementary functional and rescue experiments. However, some of the mechanistic interpretations and broader conclusions regarding telomere length inheritance in humans would benefit from additional donors and longitudinal analyses following cybrid generation, or more cautious framing.

eLife Assessment

This important study combines behavioural analysis, voltage imaging and electrophysiology to advance our understanding of muscle coordination at the cell-to-cell level, in Caenorhabditis elegans. The evidence supporting the conclusions is convincing; however, the use of correlation in some aspects of data interpretation is a relative weakness. The technically sophisticated optogenetic voltage clamp approach introduced here can be applied to other small, transparent animals, making these findings of broad interest to researchers studying electrical coupling between cells or utilising optical electrophysiology techniques.

eLife Assessment

This important study describes how selective lesions of key cortical and subcortical motor areas affect reaching actions in macaque monkeys. The results will be of interest to both basic and clinical researchers studying the neural control of movement. Kinematic analysis of movement quality is solid but could be improved by considering other metrics, especially those that relate to grasping. Evidence for the general claims related to the role of specific motor areas is incomplete because the lesions did not fully eliminate any single area while simultaneously involving neighbouring areas.

eLife Assessment

This valuable study presents a comprehensive exploration of c-di-GMP-associated protein interaction networks in Pseudomonas fluorescens, with a particular focus on biofilm-related phenotypes. The evidence is convincing, supported by a genome-wide yeast two-hybrid screen, phenotypic analyses, and experimental validation. The work identifies multiple interaction hubs and provides a resource that will be of use to the biofilm and c-di-GMP communities, while additional mechanistic exploration would further enhance its impact by clarifying the biological roles of many of the identified interactions.

Murrell et al. describe a high-throughput method, the Feeding Experimentation Device (FED3), to study food foraging strategies in mice. The authors provide solid evidence about key sex differences in foraging strategies, specifically the finding of greater male win-stay behavior. Further consideration of how sex differences could be uniquely influenced by FED3 testing conditions (e.g., single-housing, hormones) and task demands (e.g., 100-0 vs. 80-20) would be helpful. Given this open source FED3 platform, the authors provide valuable findings that have utility to the field of behavioral neuroscience, specifically to those interested in studying reward-related behavior.

This important study conducted by Hall and colleagues advances our understanding of host-pathogen co-evolution by providing an elegant multi-omic comparative framework that uncovers a profound, pathogen-directed epigenomic reprogramming of bovine alveolar macrophages uniquely driven by host-adapted Mycobacterium bovis. Convincing evidence supports these findings and draws on robust, multi-layered high-throughput sequencing data integrated with large-scale cattle GWAS metadata to prioritize actionable genetic variants linked to disease susceptibility and to highlight key immune response genes/pathways upregulated in response to infection and pathogen-specific host adaptation mechanisms.
