This study investigates the presence of DNA adenine methylation (6mA) and the associated function of TET enzyme, a DNA methylation mark eraser, in Drosophila. The study presents valuable findings on the scarcity of 6mA in the Drosophila genome and challenges previous findings regarding the role of TET in 6mA modification. The evidence supporting the claims is solid, and the paper has the potential to stimulate re-evaluations of the significance and regulatory mechanisms of 6mA DNA modifications in Drosophila.

This fundamental study advances our understanding of how Notch signaling activates transcription by analyzing dynamics of the Mastermind transcriptional co-activator and its role in the activation complex. The evidence is compelling and based on state of the art methods with precise quantitative measurements.

The current manuscript presents a cryo-EM structure of a tripartite ATP-independent periplasmic (TRAP) transporter that contributes to Haemophilus influenzae virulence. Convincing biophysical and cryo-EM experiments yield a valuable molecular model, but the functional importance of some of the molecular features identified remains to be demonstrated.

eLife assessment

This important study reports the cryo-electron microscopy structure of a multi-protein complex that recognizes the 5'-end cap of mRNAs and plays a critical role in mRNA export. The structural and biochemical analyses in this study provide convincing evidence to support the major claims of the authors, with the inclusion of more functional characterizations in cell-based systems having corroborated the claims further and and thus strengthening the study. This paper would be of interest to structural biologists and RNA biologists working on mRNA metabolism.

This manuscript used the sci-Plex system for screening compounds to improve the Ascl1-induced reprogramming from Müller glia to bipolar neurons in vitro, followed by in vivo characterization of two promising compounds in mice. The findings are valuable for future studies to develop cell replacement strategies for treatment of retinal degeneration. The strength of evidence is solid, featuring a scalable drug screening design, albeit with limited mechanistic insights.

This manuscript reports a valuable computational study of the effects of axon de-myelination and re-myelination on action potential speed and propagation failure. The manuscript presents solid evidence for the effects of de- and re-myelination in different models of working memory, with potential implications in disorders such as multiple sclerosis. The exposition of the manuscript is targeted for researchers interested in biophysical models of cognitive deficits.

This manuscript describes an important web resource for kinases connected to cytokines. The compelling information will be used by researchers across a number of fields including analysts, modelers, wet lab experimentalists and clinician-researchers, who are looking to improve our understanding of pathologies and means to correct them through modulating the immune response.

The findings of this study are valuable as they provide new insights into the role of acetylcholine in modulating sensory processing in the auditory cortex. This paper reports a systematic measurement of cell activity in the auditory cortex before and after the microiontophoretic application of Ach during an oddball and cascade sequence of auditory stimuli. The evidence presented is convincing, as the study used a rigorous experimental design and statistical analysis. The manuscript will interest researchers in auditory neuroscience and neuromodulation, as well as clinicians and individuals with auditory processing disorders.

This fundamental study explored the impact of migraine-related cortical spreading depression (CSD) on the firing of nerves innervating the coverings of the brain that are considered the putative source of migraine-related pain. Using convincing approaches they show that these responses are altered in response to mechanical deformation of the brain coverings. Given that migraine is characterized by worsening head pain in response to movement, the findings offer a potential mechanism that may explain this clinical phenomenon.

This study presents valuable findings that add to our understanding of cortical astrocytes, which respond to synaptic activity with calcium release in subcellular domains that can proceed to larger calcium waves. The proposed concept of a spatial "threshold" is based on solid evidence from in vivo and ex vivo imaging data and the use of mutant mice. Details of the specific threshold must be taken with caution and are necessarily incomplete, but may be supported by additional experiments with higher resolution in space and time in the future.

This important study reports comprehensive multi-omics data on the changes induced in young and aged male mouse tail fibroblasts after treatment with chemical reprogramming factors. The authors provide solid evidence to support their claim that chemical reprogramming factors induce changes consistent with a reduction of cellular 'biological' age (e.g., correlations with established aging markers in whole tissues).

The authors provide an important series of metabolic measurements characterizing group dynamics in fish, rationalizing that schooling behavior presents several benefits. The strength of evidence supporting this conclusion is solid, but the specific methodological and analytical approaches taken should be considered for further interpretation.

eLife Assessment

This valuable study investigates evolutionary aspects around a single amino acid polymorphism, known to be under long-term balancing selection, in an immune peptide of Drosophila melanogaster. Using alleles with different substitutions, the investigators demonstrate that while one allele provides better survival after systemic infections by a bacterial pathogen, the alternative allele endows its carriers with a longer lifespan under certain conditions. The authors suggest that these contrasting fitness effects of the two alleles contribute to balancing their long-term evolutionary fate. While the work is very interesting, the strength of the provided evidence is still incomplete, and the study would benefit from more rigorous approaches.

eLife assessment

The study presents important findings regarding a transcription-independent component of the early recovery of proteasome activity from a short pulse of proteasome inhibitor treatment, which has not been appreciated before and which is independent of the DDI2-NRF2 axis. While the evidence is in principle solid, with recapitulation in several cell line models, the proposed alternative underlying mechanism, namely regulation at the level of proteasome assembly, lacks experimental support, and at this point remain speculative.

eLife Assessment

This is a valuable study of the role that life history differences might play in determining population size and demography. While concerns about generation times and population structure leave the evidence for the claims in parts incomplete, the work is of considerable interest to anyone who tries to understand evolutionary consequences of life history changes.

This important study addresses the problem of detecting weak similarity between protein sequences, a procedure commonly used to infer homology or assign putative functions to uncharacterized proteins. The authors present a convincing approach that combines recently developed protein language models with well-established methods. The benchmarks provided show that the proposed tool is fast and accurate for remote homology detection, making this paper of general interest to all researchers working in the fields of protein evolution and genome annotation.

This fundamental study addresses a long-standing mystery in splicing regulation: does splicing occur co- or post-transcriptionally? The authors provide compelling evidence demonstrating that splicing can occur post-transcriptionally at a transcription site proximal zone, changing the way we think about splicing.

The study is an important advancement to the consideration of antimalarial drug resistance: the authors make use of both modelling results and supporting empirical evidence to demonstrate the role of malaria strain diversity in explaining biogeographic patterns of drug resistance. The theoretical methods and the corresponding results are compelling, with the novel model presented moving beyond existing models to incorporate malaria strain diversity and antigen-specific immunity. This work is likely to be interesting to malaria researchers and others working with antigenically diverse infectious diseases.
