This manuscript focuses on the identification of RNA crosslinks within the HIV RNA genome under different conditions i.e. in infected cells and in virions using a new method called HiCapR. These cross-links reveal long-range interactions that can be used to determine the structural arrangement of the viral RNA, providing useful data that show differences in the genomic organization in different conditions. The data analysis, however, is incomplete and based on extensive computational analysis from a limited number of datasets, which are in need of experimental validation.

This study reports an important new scRNAseq atlas of the mouse cranial neural plate during neural induction, patterning, and morphogenesis. The study includes a robust analysis of scRNAseq datasets covering six distinct developmental stages, as well as data describing the global transcriptional response of neural plate cells to a key ventralizing signaling molecule, Sonic Hedgehog. The computational data and validation of gene expression patterns are convincing, making this a helpful resource for investigators studying the early development of the cranial neural plate and cranial mesoderm.

This useful manuscript presents findings on Tom1p's interaction with Spt6p and its role in chromatin dynamics, supported by structural analysis through CryoEM. The evidence for the conclusions is currently incomplete, lacking key experiments including continuation in vivo interaction and orthogonal binding assays (e.g., SPR, MST, ITC) to fully support the proposed mechanism. While the results are promising, further validation is needed to strengthen the evidence and improve the manuscript's overall cohesion.

This is an important study demonstrating the importance of S100A4+ alveolar macrophages in the earlier stages of tumour development and suggesting a role in angiogenesis. As such this solid study is of interest to cancer biologists focused on early tumour development and those interested in the development of therapeutics that may specifically target early cancers.

eLife Assessment

This study represents an important advance in our understanding of how certain inhibitors affect the behavior of voltage gated potassium channels. Robust molecular dynamics simulation and analysis methods lead to a new proposed inhibition mechanism with strength of support being mostly convincing, and incomplete in some aspects. This study has considerable significance for the fields of ion channel physiology and pharmacology and could aid in development of selective inhibitors for protein targets.

This study presents important findings on cold tolerance shared between hibernating and non-hibernating mammals, identifying a key molecule, GPX4, through multi-species genome-wide CRISPR screens. The evidence supporting these conclusions is compelling, combining multi-species CRISPR screening with rigorous pharmacological assays. This work will be of significant interest to biologists studying hibernation physiology and medical researchers interested in cold tolerance.

eLife Assessment

This fundamental study addresses the regulation of the MICAL-family of actin regulators by Rab GTPases, which play a key role in directing membrane trafficking within cells. The compelling evidence explains how Rab8 family members bind at two sites to allosterically regulate MICAL1, and relieve an auto-inhibited state unable to bind actin. This study lays the basis for further progress in understanding membrane trafficking and cytoskeleton dynamics in eukaryotic cells.

eLife Assessment

This valuable study examines how different exercise training intensities affect intestinal barrier function and gut microbiota composition over a 6-week period in mice. The evidence supporting the main claims about exercise-induced intestinal injury and microbiota changes is solid, featuring comprehensive histological analysis, molecular characterization, and metabolomic profiling, though key mechanistic insights and causal relationships remain to be established. The findings have practical implications for understanding exercise-induced gastrointestinal stress, particularly the observation that daily moderate exercise may be more damaging to intestinal integrity than vigorous exercise with rest days. Additional experimental validation would strengthen these conclusions.

eLife Assessment

This valuable study uses the analysis of connectomic and transcriptomic datasets to survey the anatomy and connectivity of neurosecretory cells in the Drosophila brain. While the connectivity analyses are convincing, the anatomical and functional data provided to verify cell type identity and paracrine signaling is incomplete. Once these aspects are improved, this study would be of interest to neuroscientists working on hormonal signaling in Drosophila and other animals.

eLife Assessment

The authors examined the evolution of hepatitis C virus (HCV) in a cohort of 14 subjects with recent HCV infections. By using computational methods, they showed that viral fitness declines as the virus mutates to escape the immune response and can rebound later in infection as HCV accumulates additional mutations. The study contributes to an important aspect of viral evolution. The combination of approaches is highly compelling; however, some aspects of the manuscript are incomplete and would greatly benefit from additional revision, mainly to increase their clarity.

eLife Assessment

This important study provides evidence for the role of neutrophil extracellular traps in chronic kidney damage (CKD) induced by chemotherapy and suggests a therapeutic approach to mitigate the kidney pathology caused by the NETs. The study utilizes a sound murine in vivo model of CKD with low-dose administration cisplatin and a genetic model for impairment of NET formation by deletion of the enzyme Pad4. In its current form, the study was seen as incomplete as there is not yet formal demonstration of NET production by neutrophils in the model of CKD used. Additionally, the accuracy and clarity of data presentation could be improved.

This manuscript offers an exploration of the immune cells in the oyster Crassostrea gigas, by correlating distinct hemocyte morphotypes with specific single-cell transcriptional profiles. The evidence supporting the conclusion is convincing, deriving from the comprehensive dataset that not only captures unicellular diversity but also associates these cells with distinct immune roles, making it an important resource for the broader research community. There are some concerns on the data presentation that leave some questions.

eLife Assessment

This is a valuable study of the physiological mechanisms promoting network activity during fever in the mouse neocortex. Most of the supporting evidence is solid, however, there is incomplete support for the conclusion that the E/I balance is unchanged with temperature.

eLife Assessment

This important study describes a computational tool termed FliSimBA (Fluorescence Lifetime Simulation for Biological Applications), which uses simulations to rigorously assess experimental limitations in fluorescence lifetime imaging microscopy (FLIM), including diverse noise factors, hardware effects, and sensor expression levels. The evidence from simulation and experimental measurements supporting the usefulness of FlimSimBA is solid. The authors may improve the application of the tool to a wide range of biological samples by providing the simulation package, currently in MATLB, in other common languages such as Python, and having better descriptions of the fitting algorithm and model assumptions. The work will interest scientists who wish to perform quantitative FLIM imaging for cells and tissues.

Huson & Regehr characterize the spiking responses of UBCs to various patterns of synaptic stimulation and dissect the contributions of relevant glutamate receptors to their transformations. This study presents valuable findings describing how trains of mossy fiber stimulation control cerebellar unipolar brush cell discharges. The evidence that UBCs transform signals in diverse ways depending on their complement of AMPA, mGluR1, and mGluR2 receptors is solid.

eLife Assessment

This study provides important morphological observations related to the potential roles of Hebbian plasticity in establishing brain connectivity, by examining synapses formed by functionally distinct groups of retinal ganglion cell (RGC) axons in albino mouse dorsolateral geniculate nucleus (dLGN). Here, inappropriately projecting contralateral RGCs undergo developmental rewiring alongside ipsilateral RGCs, such that Hebbian theory would predict them to have separate synaptic targets. The authors provide compelling support for some presence of Hebbian rewiring, using combined confocal imaging and serial electron microscopy (EM) reconstructions to show that contralateral RGCs form completely segregated synaptic inputs onto islands of dLGN thalamocortical neurons, as well as somewhat segregated synaptic input onto local inhibitory interneurons. These findings will be of interest to researchers studying synaptic connectivity and plasticity during development.

In this manuscript, Wang et al describe the identification, and provide initial mechanistic characterization, of a potent probiotic strain with activity against Salmonella enterica infection. The evidence provided is compelling, with multiple and varied methodologies used to support the claims made by the authors. The findings reported are valuable to the probiotic and enteric infection subfields.

eLife Assessment

This study presents valuable findings related to seasonal brain size plasticity in the Eurasian common shrew (Sorex araneus), which is an excellent model system for these studies. The evidence supporting the authors' claims is convincing. However, the authors should be careful when applying the term adaptive to the gene expression changes they observe; it would be challenging to demonstrate the differential fitness effects of these gene expression changes. The work will be of interest to biologists working on neuroscience, plasticity, and evolution.
