This study addresses an important question in aging biology by combining metabolomics, transcriptomics, molecular genetics, and functional analyses to examine how cytosolic acetyl-CoA metabolism influences late-life fitness in replicatively aging yeast. The evidence supporting the roles of AMPK activation, mitochondrial acetyl-CoA utilization, and fatty acid synthesis in preserving fitness during aging is convincing overall, and the engineered A2A strain provides an elegant demonstration that coordinated modulation of distinct acetyl-CoA metabolic branches can increase the proportion of aged cells with a low-senescence phenotype. The study provides significant insight into mechanisms that allow aging cells to maintain fitness without extending replicative lifespan.

This work by Pyne and Pandey et al. addresses DNase X (DNase1L1) activity at the macrophage phagocytic cup, using an innovative imaging approach that couples visualization of cup formation to spatially resolve DNA degradation. The methodology is technically sound, and the central finding that DNA digestion begins prior to phagolysosomal maturation is well supported. Overall, the study is solid and provides a valuable framework for investigating early events at the phagocytic cup that may shape responses to pathogens and inflammatory disease.

eLife Assessment

This study presents a valuable framework that uses anticipatory eye movements to track how expectations are formed and revised during implicit probabilistic sequence learning. The evidence supporting a behavioural dissociation between errors arising from environmental noise and errors reflecting an inaccurate internal model is solid, but the oculomotor data describe behaviour rather than explain the underlying computational mechanisms, and the stronger mechanistic claims - that learning is more repetition-based than error-driven - remain incomplete without formal comparison against computational models of error-driven learning. The emerging reaction-time difference between conditions appears driven by slowing to low-probability stimuli rather than facilitation of high-probability ones, an asymmetry that requires decomposition and consideration of alternative explanations. The potential contamination of the anticipatory measure by starting gaze position should be addressed through control analyses, and the "process-pure" framing should be tempered, given that oculomotor behaviour is itself subject to motor learning.

This manuscript presents an important and timely contribution by incorporating desolvation barriers into coarse-grained models of biomolecular condensates. The findings are convincing, supported by a clear physical model and systematic simulations showing effects on phase behavior, packing, and dynamics. Some clarification and broader context would improve the manuscript, but it provides a foundation that will be of use for developing more realistic coarse-grained interaction schemes.

This important study identifies two pairs of dopaminergic neurons (DA-WED) in Drosophila that coordinate cardiac deceleration and locomotor responses to a mechanical threat. The conclusions are supported by convincing evidence from a combination of optogenetic, physiological, and behavioral experiments. The work provides invaluable insights into the neural coordination of behavioral and cardiac responses to threat and will be broad interest to neuroscientists, physiologists, and researchers studying brain-body interactions.

This study proposes that fitness level, but not sex, influences exercise-induced hypoalgesia in women. However, the evidence to support this claim is incomplete: the conclusions rely on a small-effect interaction that emerges only under specific conditions, the findings are inconsistent across pain modalities and stimulus intensities, and the absence of a baseline condition limits the interpretability of results as reflecting true hypoalgesia. Additionally, the methods by which fitness level was categorized across cohorts can be questioned. The results of this study could be useful to improve future experimental designs exploring these factors in more depth.

In this solid work, Fukui et al. re-examined the ATP hydrolysis mechanism in GHKL ATPases, revealing a cooperative role for two conserved acidic residues rather than a single one. This valuable study used a range of biochemical and structural techniques on various mutants from different members of the GHKL ATPase family to test and validate their proposed mechanism. An updated and extended mechanistic model of ATP hydrolysis by this class of enzymes is proposed.

eLife Assessment

This important study investigates whether high-level physical reasoning is grounded in real-time bodily and vestibular signals using an innovative combination of virtual tool-use tasks and galvanic vestibular stimulation. The evidence is solid for the specific conclusion that ongoing vestibular information can influence selected aspects of physical reasoning in a context-dependent manner, while is incomplete for the broader mechanistic interpretations.

eLife Assessment

This valuable study uses large-scale 7T naturalistic fMRI data and nonlinear pRF modeling to map the tonotopic organization of the human auditory cortex, linking spectral tuning to speech selectivity and cortical hierarchy. The evidence is solid, demonstrating that movie-based stimuli can recover robust population-level auditory maps and offering tools for leveraging existing datasets, although there is room for improvement in relating static tonotopy to dynamic speech processing and in presentation clarity. The study will be of interest to a broad audience working on auditory cortex organization and mapping.

Franziscus et al. present an important study introducing SPEx, an elegant, broadly accessible approach to subcellular spatial proteomics that combines cell expansion, laser microdissection, and mass spectrometry to enable protein profiling within defined subcellular regions. The authors provide convincing evidence that this flexible integration of established techniques offers a robust, practical, and cost-effective strategy for compartment-resolved proteomic analysis. The method is appropriately validated across multiple subcellular compartments and complementary workflows, demonstrating its ability to recover known protein markers while identifying previously uncharacterised components. The study also provides a characterisation of the method's capabilities and limitations. Overall, SPEx is likely to be of broad interest to cell biologists seeking to map organelle composition.

eLife Assessment

By using a combination of patch clamp recordings, calcium imaging and computer modeling, the authors analyze the spatial distribution of voltage gated calcium channels at glutamatergic synapses formed between layer 5 pyramidal neurons (L5PNs) and between layer 2/3 and L5PNs in the prefrontal cortex (PFC) and primary somatosensory cortex (S1); they conclude that the calcium channel-vesicle coupling is looser in the PFC compared to S1, and future ultrastructural studies may directly confirm the proposed differences in the spatial organization of voltage-gated calcium channels and vesicular release sites. Overall, these findings are important because they have implications for shaping synaptic plasticity and neural circuit function across brain regions. They are convincing because they are based on the use of a multi-pronged approach, although the presentation would benefit from stronger integration of the current findings with the existing literature and a more explicit discussion of potential limitations and confounding factors for data interpretation.

This study reports the relative importance of Tie1 and Tie2 signaling for atrial versus ventricular trabeculation. It is an important study and is one of the few works to date that have carefully and simultaneously analyzed these two processes. In line with a previous study in zebrafish, the authors demonstrate key differences between atrial and ventricular trabeculation. While the imaging and quantitative analyses are conducted using solid and validated methodologies throughout the manuscript, future studies using additional experimental approaches will be invaluable to further establish the underlying mechanisms.

eLife Assessment

This study reports a novel function for syntaxin 11, a specialized SNARE protein critical for the immune system whose mutations cause familial hemophagocytic lymphohistiocytosis type 4. The data convincingly show that depletion of STX11 impairs store-operated calcium entry in Jurkat T cells and that this defect is recapitulated in primary cells from a patient suffering from the disease; the authors further show that the syntaxin interacts with the pore subunit of the ORAI1 channel and propose that it primes the channel by promoting the assembly of multimers before activation by its endogenous ligand, the ER Ca2+ sensing protein STIM1. This is a conceptually important claim that challenges the prevailing view that all structural transitions in ORAI1 are STIM-driven. The high-quality data strongly support the interpretations, but the discussion would be strengthened if the authors suggest alternative mechanisms and mention earlier studies reporting ORAI1 regulation by vesicular trafficking.

eLife Assessment

This important study provides detailed insights into the metabolic states of hemocyte populations across developmental stages and in both physiological and pathological contexts, including during immune challenge. The study provides convincing evidence by comparing the relative utilization of glycolysis and oxidative phosphorylation in Drosophila larval immune cells, and can have implications for metabolic programs that shape immune function in health and disease.

eLife Assessment

This valuable study demonstrates that a multi-step differentiation program in bacteria combining a bistable switch with two quorum-sensing systems is capable of generating autonomous and self-organized spatial patterns. The evidence for the core engineering system using fluorescent reporters support patterning across several conditions is convincing and has significant implications on the process of cell differentiation.

eLife Assessment

This important study combines single-molecule imaging and CUT&TAG to address the molecular mechanism underlying the differentiation process that initiates the formation of red blood cells in the bone marrow. The authors provide evidence that the transcription factor GATA2 transiently associates with a new set of genomic loci early in the differentiation process before it is replaced by GATA1. Together, the experiments across three biological systems are solid, but they could benefit from additional details and controls to strengthen the conclusions.

eLife Assessment

This study provides fundamental insights by demonstrating that the Nanog mRNA coding sequence (CDS) and 3′UTR domains are spatially segregated and functionally distinct in pluripotent stem cells and blastocysts, with 3′UTR-enriched border cells primarily influencing morphogenesis and CDS-enriched inner cells largely regulating transcription and epigenetic programs. The work opens a novel conceptual avenue for understanding how separable mRNA domains can differentially control cell behavior and differentiation. However, the evidence is incomplete, as key aspects of the molecular nature, biogenesis, and precise characterization of the separated 3′UTR and CDS RNA species, as well as causal links between their perturbation and the observed phenotypes (e.g., via rescue and deeper characterization of 3′UTR elements), remain to be fully established.

eLife Assessment

The authors propose a "simplified" model for intrinsically bursting neurons with explicitly controllable parameterization of oscillatory dynamics. The evidence that the modeling approach is generally appropriate and practical for modeling rhythmic bursting neurons and neural circuits is currently incomplete. Based on what the authors present, this model appears to have limited neurobiological relevance and utility but may be useful as a controller for an artificial system, such as in neuro-robotics applications.

There is a need for better and safer dengue virus live attenuated vaccines. This manuscript describes important findings that could lead to the design of a strongly immunogenic, tetravalent live attenuated vaccine for dengue, without the risk of causing antibody-dependent enhancement. However, the experimental evidence presented is incomplete since only constructions of one serotype were tested to prove the principle.

This study presents important findings linking peripheral inflammation to the remodeling of perinodal adipose tissue and draining lymph nodes, suggesting a mechanism by which local tissue inflammation can reshape LN structure and metabolism. The evidence is solid and supported by observations, future studies will address any outstanding questions.
