  This work provides an important framework for understanding the primary causes of disease. While the theoretical results rely on strong assumptions about the underlying causal mechanisms, the authors provide solid empirical evidence that the framework is robust to modest violations of these assumptions.

  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 valuable 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.

  eLife Assessment

  This valuable study assesses epigenetic clocks across ancestries, including in the context of accelerated aging in Alzheimer's Disease patients. It provides convincing evidence for population differences in age estimation accuracy across a variety of epigenetic clocks, but the degree to which these differences reflect continuous variation in ancestry, and/or are confounded by environmental or power differences is not entirely clear; consequently, the evidence that reduced portability is rooted in genetics is incomplete. Given the accelerating use of epigenetic clocks across fields, this study is nevertheless likely to be of interest to researchers working on human genetic and epigenetic variation or who apply epigenetic clocks to diverse human populations.

  This valuable study suggests that the dosage compensation complex and m6A act in a feedback loop in Drosophila melanogaster. The study provides integrated analyses of RNA sequencing and mapping data of the m6A RNA modification in the context of unbalanced genomes, which suggests that m6A modification status may influence H3K16Ac deposition through regulation of the acetyltransferase MOF. However, it is not clear whether this regulation is directly or indirectly related to m6A regulation. The evidence is considered incomplete due to technical concerns, as quantitative assessments were made using non-quantitative methods.

  Editors Assessment:

  Among hot topics in coral reef research, the difference between anemonefish and other damselfish is currently a popular area of research. In this study the authors provide a new high-quality non-anemonefish genome, which will be of high relevance to further the depth of such analyses. In this case of the sapphire damselfish Chrysiptera cyanea, a widely distributed damselfish in the Indo-Pacific area, often studied to elucidate the roles of various environmental controls on their reproduction, and investigate related hormonal processes To further the potential of biomolecular analyses based on this species, this study generated the first genome of a Chrysiptera fish from a male individual collected in Okinawa, Japan. Using PacBio and HiFI long-read sequencing with 94.5x coverage, a chromosome-scale genome was assembled and 28,173 genes identified and annotated. Peer review gathered more parameters and details on the quality, and the final assembly comprised of 896 Mb pairs across 91 contigs, and a BUSCO completeness of 97.6%. This reference genome should therefore be of high value for future genetic-based approaches, from population structure to gene expression analyses.

  eLife Assessment

  Using genomic data from ancient and modern samples, this important study investigates the genomic history of cattle in Iberia, focusing on the admixture between domestic cattle and their wild ancestors, aurochs. The authors present convincing evidence for interbreeding between domestic cattle and wild aurochs since the Neolithic period, although the evidence of sex-biased introgression is weak. The authors also show that the aurochs ancestry in cattle stabilized at ~20% since ~4000 years ago and continues into modern breeds; however, the aurochs ancestry is not heightened in a modern breed of Spanish fighting bulls that are bred for aggressiveness. The work will be of interest to evolutionary biologists and quantitative geneticists who seek to understand the genomic history and genetic basis of trait variation of domesticated animals.

  eLife Assessment

  This study reports valuable insights into the interactome of the RNA-binding protein SERBP1 and possible links through PARylation to diverse processes, including splicing, cell division, and ribosome biogenesis. The diversity of processes SERBP1 may regulate means this work would be of very broad interest to the cell biology community. The proteomics data are solid, but the functional connection to downstream processes and the link to Alzheimer's disease, while compelling, still require further examination. These latter data currently rely on a very limited set of experiments and patient samples with questionable quality of preservation and methodology.
