This valuable study illuminates molecular movements of acid-sensing ion channels by combining advanced chemical biology and biophysical techniques. The evidence for the main claim, lack of interaction of molecular termini, is compelling and challenges prior models. This work is expected to pique interest in the ion channel signaling field, providing a fresh perspective.

This carefully executed study provides a comparison of the chemical composition of mouse urine across strain and sex with the responses of vomeronasal sensory neurons, which are responsible for detecting chemical social cues. While the authors did not examine all molecular classes found in mouse urine or directly test whether the urinary volatile chemicals that vary with sex and strain are effective vomeronasal neuron ligands, solid data are provided that will be of significant interest to those studying chemical communication in rodents. This work should provide a valuable foundation for future research that will determine which molecules drive sex- and strain-specific vomeronasal responses.

This intracranial EEG study presents important and convincing neural evidence supporting the high spatial specificity (receptive field) of visually driven alpha-band oscillation in human brains and its potential role in exogenous cuing attention. The work challenges the predominant view about the role of alpha-band oscillation in visual attention and advocates that stimulus-driven alpha suppression is precisely tuned and might contribute to exogenous spatial attention.

In this valuable study, the authors use a computational model to investigate how recurrent connections influence the firing patterns of grid cells, which are thought to play a role in encoding an animal's position in space. The work suggests that a one-dimensional network architecture may be sufficient to generate the hexagonal firing patterns of grid cells, a possible alternative to attractor models based on recurrent connectivity between grid cells. However, the support for this proposal was incomplete, as some conclusions for how well the model dynamics are necessary to generate features of grid cell organization were not well supported.

This study reports valuable findings on the correlation between the positions of dendritic mitochondria and the orientation preference of calcium responses of individual spines. The conclusion about the biased localization of dendritic mitochondria near functional diverse spines is informative to understand the functions of dendritic mitochondria. The experimental evidence supporting the conclusion is compelling.

The manuscript offers useful descriptive insights into the potential influence of whole-brain lactate and pH levels on the manifestation of behavioral phenotypes seen in diverse animal models of neuropsychiatric disorders. However, reviewers have raised concerns about the potential loss of specificity in capturing regional and cell-type-specific effects when relying solely on whole-brain analysis methods. While the evidence supporting the conclusions is largely solid, the robustness of these conclusions could be enhanced by the inclusion of additional data and further analysis.

This important study uses a range of technical approaches to investigate the responses of zona incerta neurons to movement and sensory stimuli. The majority of neurons exhibited movement related activity but only a small proportion were modulated by whisker deflections. The major conclusion of the study is that the zona incerta distributes a general motor signal. The evidence supporting this claim is solid, although the study would be improved by greater transparency and discussion of experimental methods and histological verification of recording sites, viral spread, and which territories of the zona incerta were investigated. The work will be of interest to behavioral and physiological neuroscientists.

This important manuscript by Genzoni et al. reports the striking discovery of a regulatory role for trophic eggs in ant caste determination. Prior to this study, trophic eggs were widely assumed to play only a nutritional role in the colony, but this compelling study shows that trophic eggs can suppress queen development, and therefore regulate caste determination in specific social contexts.

eLife Assessment

The study is considered important with solid evidence that demonstrates the impact of plasma membrane nano-domains and protein interactions in the plant defence response to viruses. It includes a molecular understanding of the role of a calcium dependent kinase (CPK3) and a remorin protein in the cell-to-cell spread of viruses and cytoskeletal dynamics demonstrating, conclusively, the role of CPK3 with multiple lines of evidence. The work opens avenues to investigate different viruses and other plasma membrane proteins to gain a fuller picture of the involvement of plasmodesmata and other nanodomains in virus spreading.

eLife assessment

This important study identifies the gene mamo as a new regulator of pigmentation in the silkworm Bombyx mori, a function that was previously unsuspected based on extensive work on Drosophila where the mamo gene is involved in gamete production. The evidence supporting the role of Bm-nano in pigmentation is convincing, including high-resolution linkage mapping of two mutant strains, expression profiling, and reproduction of the mutant phenotypes with state-of-the-art RNAi and CRISPR knock-out assays. The work will be of interest to evolutionary biologists and geneticists studying color patterns and evolution of gene networks.

eLife assessment

This work presents convincing evidence for the presence of wooly mammoth/rhinoceros ancient environmental DNA (aeDNA) far from the time likely to host living individuals: what is effectively a genetic version of a geological inclusion. These are important findings that will have ramifications for the interpretation and conclusions extracted from aeDNA more generally.

eLife assessment

This study addresses an important question in sensory neuroscience: how the olfactory system distinguishes decreases in stimulus intensity from decreases in neural responses due to adaptation. Based on a combination of electrophysiological and behavioral analyses, solid evidence establishes that neural coding changes differently between intensity reductions and adaptation. Intriguingly, behavioral responses tend to increase as the neural responses decrease, suggesting that core features of the odor response persist through adaptation. While the experimental results are convincing overall, the conclusions would be strengthened by more refined statistical analysis and data quantification.

This convincing manuscript represents a valuable advance in understanding the role of MCT1 – a transporter for lactate and other organic anions – in hepatocytes and hepatic stellate cells in the liver. The authors also generate exciting new tools to investigate hepatic stellate cell biology, and these may have much broader applications, but future studies are required to validate these new tools.

eLife assessment

This important study presents an exhaustive structural analysis of a complete tripartite HipBST toxin-antitoxin system of the Enteropathogenic E. coli O127:H6, which represents a fascinating variation on the well-studied HipAB toxin-antitoxin system. The convincing data show that major features of the canonical HipAB system have been rerouted to form the tripartite HipBST, revealing a new mode of inhibition of a toxin kinase.

The paper addresses the mechanism of initiation of DNA replication in human cells by analyzing published data on the location of origins of DNA replication and the location of binding sites in the genome for ORC and MCM2-7 complexes. There are some useful analyses of existing data but there are concerns regarding the conclusion that there might be alternative mechanisms for determining the location of origins of DNA replication in human cells compared to the well known mechanism known from many eukaryotic systems, including yeast, Xenopus, C. elegans and Drosophila. The lack of overlap between binding sites for ORC1 and ORC2, which are known to form a complex in human cells, is a particular concern and points to the evidence for the accurate localization of their binding sites in the genome being incomplete.

eLife assessment

This important study combines experiments and mathematical modelling to enhance our understanding of the interplay between the two flight muscles in birds during slow flight. The evidence for the findings is compelling, derived from new methods for measuring wing shape and force production combined with previously validated methods in muscle physiology. This work will be of broad interest to comparative biomechanists.

eLife assessment

This study presents a valuable set of experiments to test whether Bombus terrestris bumblebees can detect lethal-level doses of a series of pesticides in nectar-mimicking sugary solutions. Behavioural essays were coupled with electrophysiological measurements to show that B. terrestris mouthparts cannot detect high levels of the tested pesticides. If confirmed using pesticide formulas, and other bumblebee species, the study will be of general interest in environmental science research. Most experimental data are compelling, and the conclusions are sound, but the write-up would benefit from a broader ecological context.

This fundamental work substantially advances our understanding of animals' foraging behaviour by monitoring the movement and body posture of barn owls in high resolution and assessing their foraging success. With a large dataset, the evidence supporting the main conclusions is compelling. This work provides new corroboration for motion-induced sound camouflage and has broad implications for understanding predator-prey interactions.
