This fundamental work provides evidence that glutamate and GABA are released from different synaptic vesicles at supramammillary axon terminals onto granule cells of the dentate gyrus. The study uses complementary electrophysiological and anatomical experimental approaches. Together, these provide convincing evidence that the co-release of glutamate and GABA from different vesicles within the same terminal could modulate granule cell firing in a frequency-dependent manner, although thorough elimination of alternative mechanisms would have strengthened the study. The work will be of interest to neuroscientists investigating co-release of neurotransmitters in various synapses in the brain and those interested in subcortical control of hippocampal function.

This important study describes the development and validation of an Automated Reproducible Mechano-stimulator (ARM), a tool for standardizing and automating tactile behavior experiments. The data supporting the use of the ARM system are compelling, and demonstrate that by removing experimenter effects on animals, it reduces variability in various parameters of stimulus application. Moreover, the authors demonstrate that any noise emitted from the ARM does not induce an increased stress state. Once commercially available, the ARM system has the potential to increase experimental reproducibility between laboratories in the somatosentation and pain fields.

This important paper on measuring molecular connectivity using combined serotonin PET and resting-state fMRI provides both novel methods for studying the brain as well as insights into the effects of ecstasy administration. The methods are convincing, with the high anaesthetic dose used likely limiting network activity.

This valuable paper investigates how fish avoid thermal disturbances that occur on fast timescales. The authors use a creative experimental approach that quickly creates a vertical thermal interface, which they combine with careful behavioral analyses. The evidence supporting their results is solid, but there is a potential confounding factor between temperature and vertical positioning, and characterization of the thermal interface would greatly assist in interpreting the results.

This valuable study uses zebrafish as a model to reveal a role for the cell cycle protein kinase CDK2 as a negative regulator of type I interferon signaling. The evidence supporting the authors' claims is convincing, including both in vivo and in vitro investigative approaches that corroborate a role for CDK2 in regulating TBK1 degradation. In this latest version, the authors included data addressing a concern raised by the reviewer in the previous peer review round. This work will interest cell biologists, immunologists, and virologists.

The manuscript presented by Moyse and colleagues provides valuable insight into the origin, morphology, dynamics, and behavior of several populations of mononuclear phagocytes in the zebrafish heart. The study presents solid evidence through the use of transgenic lines and live imaging, although some limitations related to lineage tracing and molecular profiles should be considered. This work exemplifies the use of zebrafish as a model to study the role of leukocytes in cardiac development and regeneration and potentially draw broader interest to biologists working in immunology fields.

eLife Assessment

In this manuscript, the authors present valuable findings on the apparent role of a salience-network anterior insula node in directing fronto-parietal and default-mode network activity within a tripartite network during control of memory, drawn from an impressive invasive human neurophysiological dataset. Overall, the authors have presented a convincing set of analyses. We also commend the use of a large intracranial EEG dataset to approach this question.

In this useful study, the authors tested the ability of bumblebees to use bird-view and ground-view for homing in cluttered landscapes using modeling and behavioral experiments, claiming that bumblebees rely most on ground-views for homing. However, due to a lack of analysis of the bees' behavior during training and a lack of information as to how the homing behavior of bees develops over time, the evidence supporting their claims is currently incomplete. Moreover, there was concern that the experimental environment was not representative of natural scenes, thus limiting the findings of the study.

eLife Assessment

This manuscript focuses on understanding if and how the glycosylation of SARS-CoV2 spike protein affects a putative allosteric network of interactions controlled by the binding of a fatty acid. The main conclusion is that glycans do not significantly affect the network of allosteric interactions. This valuable information - albeit mainly consisting of negative results - is based on convincing evidence. It will be of interest to scientists focusing on SARS CoV2 protein structure and dynamics.

This study describes a useful antibody-free method to map both G-quadruplexes and R-loops in vertebrate cells independently of the BG4 and S9.6 antibodies. It also reveals that the helicase Dhx9 can affect the self-renewal and differentiation capacities of mESCs, perhaps by regulating co-localized G4s and R-loops. The datasets provided might constitute a good starting point for future functional studies, and although the strength of the evidence that DHX9 interferes with the ability of mESCs to differentiate by regulating directly the stability of either G4s or R-loops has been improved compared to a previous version, it is still incomplete.

eLife Assessment

This is a valuable study that tests the functional role of food-washing behavior in removing tooth-damaging sand and grit in long-tailed macaques and whether dominance rank predicts level of investment in the behavior. The evidence that food-washing is deliberate is compelling and the evidence that individual investment in the behavior varies is solid. Overall, the paper should be of interest to researchers interested in foraging behavior, cognition, and primate evolution.

eLife Assessment

The authors performed extensive coarse-grained molecular dynamics simulations of 140 different prion-like domain variants to interrogate how specific amino acid substitutions determine the driving forces for phase separation. The analyses are solid, and the derived predictive scaling laws can aid in identifying potential phase-separating regions in uncharacterized proteins. Overall, this is a valuable contribution to the field of biomolecular condensates. It exemplifies how data-driven methodologies can uncover new insights into complex biological phenomena.

This study highlights an important discovery: a bacterial pathogen's effector influences plant responses that in turn affect how the leafhopper insect vector for the bacteria is attracted to the plants in a sex-dependent manner. The research is backed by convincing physiological and transcriptome analyses. This study unveils a complex interdependence between the pathogen effector, male leafhoppers, and a plant transcription factor in modulating female attraction to the plant, shedding light on previously unexplored aspects of plant-bacteria-insect interactions.

eLife Assessment

This study delivers valuable new insights into the neural circuits involved in post-mating responses (PMR) in Drosophila females, supported by convincing evidence that the circuits for mating receptivity and egg-laying are distinct. The new experimental evidence adds to the current understanding the neural circuits and molecular mechanisms underpinning PMR.

These important findings detail the role of Pim1 and Pim2 in controlling the behaviour and activity of 'killer' T cells; a vital cell within of our immune system. The authors capitalized on high resolution quantitative analysis of the proteomes and transcriptomes of Pim1/Pim2-deficient CD8 T cells to provide compelling evidence for how the PIM1/2 kinases control TCR-driven activation and IL-2/IL-15-driven proliferation and differentiation into effector T cells. It's also noteworthy that Pim1/Pim2 impact is better revealed through quantitative proteomics than transcriptomics.

This important body of work uses state-of-the-art quantitative methods to characterize and compare behaviors across five different fish species to understand which features are conserved and which ones are differentiated. The convincing results from this study will be of interest to ethologists and also have potential utility in understanding the neural mechanisms leading to these behaviors.

This fundamental study provides a near-comprehensive anatomical description and annotation of neurons in a male Drosophila ventral nerve cord, based on large-scale circuit reconstruction from electron microscopy. This connectome resource will be of substantial interest to neuroscientists interested in sensorimotor control, neural development, and analysis of brain connectivity. However, although the evidence is extensive and compelling, the presentation of results in this very large manuscript lacks clarity and concision.

This paper describes an important advance in an in vitro neural culture system to generate mature, functional, diverse, and geometrically consistent cultures, in a 384-well format with defined dimensions and the absence of the necrotic core, which persists for up to 300 days. The well-based format and conserved geometry make it a promising tool for arrayed screening studies. Some of the evidence is incomplete and could benefit from a more direct head-to-head comparison with more standard culture methods and standardization of cell seeding density as well as further data on reproducibility in each well and for each cell line.

eLife assessment

This important study describes the crystallographic screening of a number of small molecules against a viral enzyme critical for the 5' capping of SARS-CoV-2 RNA and viral replication. While the high-quality crystal structures and complementary biophysical assays in this study provide solid evidence to support the major claims regarding how these small molecule compounds bind to the viral enzyme, the mismatch between the antiviral activity and binding to the viral enzyme of several small molecule compounds could have been more thoroughly investigated or discussed. This paper would be of interest to the fields of coronavirus biology, structural biology, and drug discovery.

This landmark study elucidates the intricate structural mechanisms by which both covalent and non-covalent synthetic ligands can co-occupy the binding pocket of the nuclear receptor transcription factor PPARγ. Through a compelling integration of structural, biochemical, and biophysical evidence, the authors challenge the reliability of two commonly used covalent inhibitors. These findings have far-reaching implications for the broader field of nuclear receptor research. This work will be of high interest to structural biologists and biochemists exploring ligand interactions within the nuclear receptor superfamily.
