This manuscript offers valuable theoretical predictions on how horizontal gene transfer (HGT) can lead to alternative stable states in microbial communities. Using a modeling framework, solid theoretical evidence is provided to support the claimed role of HGT. However, given that the model has many degrees of freedom, a more comprehensive analysis of the role of different parameters could strengthen the study. Additionally, potential interactions between plasmids that carry out HGT are not discussed in the model. This paper would be of interest to researchers in microbiology, ecology, and evolutionary biology.

This important study compares the cortical projections to primary motor and sensory areas originating from the ipsilateral and contralateral hemispheres. Results show that, while there is substantial symmetry between the two hemispheres regarding the areas sending projections to these primary cortical areas, contra-hemispheric projections had more inputs from layer 6 neurons than ipsi-projecting ones. The evidence is compelling and the conclusions are supported by rigorous analyses.

This important study characterizes the molecular signatures and function of a type of enteric neuron (IPAN) in the mouse colon, identifying molecular markers (Cdh6 and Cdh8) for these cells. A battery of compelling and comprehensive experimental findings suggests data from other species are likely translatable to mice, bridging the abundant literature from humans and other mammals into this experimentally tractable animal model. This work will be of interest to scientists studying the motor control of the colon and more generally the enteric neuromuscular system.

The authors use a multidisciplinary approach to provide a link between Beta-alanine and S. Typhimurium (STM) infection and virulence. This valuable work shows how Beta-alanine synthesis mediates zinc homeostasis regulation, possibly contributing to virulence. The work is convincing as it adds to the existing knowledge of metabolic flexibility displayed by STM during infection.

eLife Assessment

This important study reports on a basis for neurabin-mediated specification of substrate choice by protein phosphatase-1. The data from the comprehensive approach using structural, biochemical, and computational methods are compelling. This paper is broadly relevant to those investigating various cellular signaling cascades that entail phosphorylation as the main mechanism.

This solid paper reports on the use of artificial intelligence to assess bone marrow adipose tissue in the skull. The method employing MRI is novel and that approach allows for the identification of genetic loci that regulate this trait as well as others using data from the UK biobank. Overall this is an important contribution although the authors should consider several points: 1-validation of the T1-weighted MRI signal intensity; 2-further discussion of the sex differences; and 3-cross-trait linkage disequilibrium score regression (LDSC) for osteoporosis, Parkinson's disease, and cognitive function.

eLife Assessment

This paper provides a useful systematic quantification of the relationship between electrophysiological response properties of single neurons with their position in the brain. The quality of the classification setup is high and the methodology is solid.

eLife Assessment

This valuable study clarifies the mechanism by which the kinesin-10 motor protein, chromosome-associated kinesin, Kid (KIF22), enables chromosome movement during mitosis, demonstrating that human and Xenopus Kid proteins function as processive, homodimeric kinesins capable of processive microtubule plus-end motility. The convincing work highlights that Kid can recruit and transport duplex DNA along microtubules via its conserved C-terminal DNA binding domain, revising our understanding of chromokinesins' role in chromosome motility during mitosis. Although the data are robust, the manuscript would benefit from some editing for clarity.

eLife Assessment

This important study uses Mendelian Randomization to provide evidence that early-life reproductive phenotypes (i.e., age at onset of menarche and age at first birth) have a significant impact on numerous health outcomes later in life. The empirical evidence provided by the authors supporting the antagonistic pleiotropy theory is solid. Theories of aging should be empirically tested and this study provides a good first step in that direction.

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 important work combines self-report, neural and physiology data to examine the efficacy and mechanisms of counter conditioning versus extinction in reducing re-emergence of conditioned threat responses and show that this appears to rely on the nucleus accumbens rather than the ventromedial prefrontal cortex. These findings are supported by convincing evidence, though some areas could benefit from a few targeted refinements. The findings will be of interest to researchers across multiple subfields, including neuroscientists, cognitive theory researchers, and clinicians, particularly those with an interest in clinical applications in trauma therapies.

eLife Assessment

This study addresses an important and longstanding question regarding the molecular mechanism of protein misfolding in Ig light chain (LC) amyloidosis (AL), a life-threatening condition. By combining advanced techniques, including small-angle X-ray scattering, molecular dynamics simulations, and hydrogen-deuterium exchange mass spectrometry, the authors provide convincing evidence that the "H state" distinguishes amyloidogenic from non-amyloidogenic LCs. These findings not only offer novel insights into LC structural dynamics but also hold promise for guiding therapeutic strategies in amyloidosis and will be of particular interest to structural biologists, biophysicists, and many others working on amyloid diseases.

This basic research study presents useful data concerning the menstrual fluid composition and its potential for endometriosis biomarker research. However, despite solid bioinformatics analyses, the choice of markers used to separate or identify the different cell types needs to be justified and the results better discussed in relation to current knowledge of the pathophysiology of endometriosis.

eLife Assessment

This study provides valuable insights into the host's variable susceptibility to Mycobacterium tuberculosis, using a novel collection of wild-derived inbred mouse lines from diverse geographic locations, along with immunological and single-cell transcriptomic analyses. While the data are convincing, a deeper mechanistic investigation into neutrophil subset functions would have further enhanced the study. This work will interest microbiologists and immunologists in the tuberculosis field.

eLife Assessment

This important and well-written study uses functional neuroimaging in human observers to provide compelling evidence that activity in the early visual cortex is suppressed at locations that are frequently occupied by a task-irrelevant but salient item. This suppression appears to be general to any kind of stimulus and also occurs in advance of any item actually appearing. The work will be of great interest to psychologists and neuroscientists examining attention, perception, learning and prediction.

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

The study describes a useful tool for assessing microglia morphology in a variety of experimental conditions. The MorphoCellSorter provides a solid platform for ranking microglia to reflect their morphology continuum and may offer new insight into changes in morphology associated with injury or disease. While the study provides an alternative approach to existing methods for measuring microglia morphology, the functional significance of the measured morphological changes were not determined.

eLife Assessment

This important study identifies species- and sex-specific neuronal cell types and gene expression in the preoptic area (POA) to help understand the evolutionary divergence of social behaviors. The evidence from single-nucleus RNA sequencing and immunostaining is compelling and suggests that cellular differences in the POA may contribute to behavioral variations such as mating and parental care that are apparent in two closely related deer mouse species. These rich observations provide an entry point for future hypothesis-driven experiments to demonstrate a causal role for these populations in sex- or species-variable behaviors in vertebrates. These data will be a resource that is of value to behavioral neuroscientists.

eLife Assessment

In this potentially valuable computational study, the authors conducted atomistic and coarse-grained simulations to probe the temperature-dependent phase behaviors of ELF3, a disordered component of the evening complex in plant. The results aim to highlight the role of polyQ tracts in modulating the temperature sensitivity. The level of evidence is considered incomplete, due to the lack of systematic calibration of the coarse-grained model and limited statistical uncertainty analysis, especially considering the relatively subtle nature of the differences due to temperature change.

eLife Assessment

This study presents a useful finding for the ferroptosis-mediated tumor microenvironment (TME) in triple-negative breast cancer (TNBC) using public single-cell RNA sequencing (scRNA-seq) and bulk RNA sequencing data. The data were collected and analyzed using solid and validated methodology and can be used as a starting point for functional studies of TME in TNBC. The work will be of interest to medical biologists working in the field of TNBC.
