  Evaluation Summary:

  This paper is potentially of broad interest to researchers in the chromosome biology field. With specific loading sequences identified, the condensin DC complex studied here provides an elegant system to investigate the in vivo activities of SMC complexes. Combining Hi-C, ChIP-seq and RNA-seq, the authors have a comprehensive suite of assays to probe their questions. However, not all of their major conclusions are currently supported by the data.

  Evaluation Summary:

  He and collaborators analyse eight samples from six patients with acral melanoma through single-cell RNA sequencing. They describe the tumour microenvironment in these tumours, including descriptions of interactions among distinct cell types and potential biomarkers. The study is thoroughly done. In its final form, this study will help to inform our knowledge of the immune infiltration on the poorly studied acral melanoma subtype, the most common type of the disease in several countries in Africa, Asia and Latin America.

  Evaluation Summary:

  This manuscript is of broad interest to readers interested in heterogeneity in immune cell populations with single-cell RNA sequencing, and for students of human T cell biology. It uses and reanalyses published single-cell RNA sequencing data dataset for this purpose. However, it does not adequately address major technical concerns, and therefore the interpretations are not robustly supported.

  Evaluation Summary:

  This manuscript extends the evidence that ribosomal DNA has substantial interindividual variation, and presents evidence that variants are associated with differences in DNA methylation. The authors show that some rDNA types respond to environmental signals during in utero development, whereas others are changed during the aging process - thus broadening the known communication between development/nutrition/aging and the cellular protein synthesis machinery. These findings have relevance for the influence of such epialleles on gene expression and disease risk.

Ecology, more than antibiotics consumption, is the major predictor for the global distribution of aminoglycoside-modifying enzymes

• Curated by eLife

  Evaluation Summary:

  This paper will be of interest to microbiologists, clinicians, and public health workers with an interest in the possible impact of antibiotic use and regulations. The scope of the study is unusually high, integrating economic and geographical factors as well as genomic data among others. However, reasonable alternative explanations can be identified such that the data do not strongly favor the preferred hypothesis put forward by the authors.

  This study provides a valuable data resource to study the systemic effects of severe COVID-19. It shows compelling evidence that the transcriptional response to COVID-19 is coordinated across the body, and it highlights cell interactions between macrophages and endothelial cells in COVID-19. This analysis and the associated resource will be valuable to understand the pathogenic mechanism of long-COVID.
