     This manuscript provides important insights into how U2AF2-dependent intron retention regulates the localization and function of long noncoding RNAs, with convincing evidence supported by multiple complementary approaches. The work is notable for linking intron retention to nuclear speckle localization and cellular phenotypes, including proliferation and migration, although the mechanistic basis remains incompletely resolved. Overall, the study presents a compelling dataset with clear biological implications but would benefit from additional analyses to strengthen mechanistic interpretation and generality.

     This potentially useful paper presents an intriguing hypothesis about the evolutionary origins of the SLC25 family of mitochondrial carrier proteins common to all eukaryotic life, proposing that all members originated from the ADP/ATP carrier (AAC) and that AAC itself may have emerged from bacterial homologs such as CysZ and YihY. While the phylogenetic analyses and structural searches are reasonable methodologies to explore ancient evolutionary events, the evidence provided here is deemed to provide incomplete support for the conclusion that the mitochondrial ATP transporter is related to CysZ and Yih.

     This study addresses an important question in aging biology by combining metabolic, genetic, and functional approaches 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 shaping distinct aging-associated phenotypes is convincing overall, with the engineered A2A strain providing a particularly elegant demonstration of coordinated metabolic regulation. However, several conclusions would benefit from clarification or moderation, particularly regarding the relationship between late-life fitness and replicative lifespan, the interpretation of "senescence," the proposed existence of distinct aging subpopulations, and the extent to which the data support mechanistic claims about lipid starvation, acetyl-CoA excess, and chromatin-based aging pathways.

     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 considered well supported, though some mechanistic claims may benefit from further evidence and more cautious framing. 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.

     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 a valuable 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 evidence is convincing, supported by comprehensive optogenetic, physiological, and behavioral experiments showing that these neurons are required for and sufficient to drive threat-associated cardiac slowing. The proposed role of cardiac deceleration as an interoceptive contributor to locomotion is intriguing, but should be presented more cautiously, as the causal relationship between heartbeat changes and locomotor output remains less directly established. The work will be of broad interest to those interested in neural circuits, neuromodulation, and the integration of physiological and behavioral responses.

     This study proposes that fitness level influences exercise-induced hypoalgesia in women. However, the evidence to support this claim is incomplete: the conclusions rely on a small interaction that emerges only under specific conditions and are incongruent with the title, the findings are inconsistent across pain modalities and stimulus intensities, the analysis approach does not fully exploit the continuous pain ratings collected, 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, and the results and figures do not clearly illustrate how between-group comparisons were conducted. With a proper revision, it could be useful for sports medicine practitioners to consider how they administer exercise protocols to help those experiencing pain.

     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 useful 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.

      This valuable 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 incomplete, as the main claims rely on limited and partially exploratory effects, including uncorrected multiple comparisons and cross-study comparisons that weaken the strength of the conclusions. The work, if it can be supported by clearer statistical support and more cautious interpretation, will be of interest to researchers in embodied cognition and physical reasoning.
