To read the full abstract: Nature 2017;548:413-419Over recent years, the Yearbook has followed the rapid advances in CRISPR-Cas9 gene editing technology, initially as a widely adopted research tool, but also as an emerging form of gene therapy. Here, Ma et al. report the first use of CRISPR–Cas9 to efficiently and safely correct a pathogenic heterozygous mutation in human embryos. The...

Brief summary: In this double-blind, randomized, placebo-controlled trial, bempedoic acid (Nexletol) reduced the incidence of a composite cardiovascular.Comment: Bempedoic acid is an ATP citrate lyase inhibitor. ATP citrate lyase catalyses the conversion of citrate to acetyl-CoA, the fundamental substrate required for the synthesis of cholesterol and fatty acids. By inhibiting the cholesterol synthesis pathway, bempedoic acid reduces intra-hepatic LDL-C....

To read the full abstract: Nat Med 2020;26(4):485–497.More than 100 medical and scientific organizations supported this international consensus statement, which describes impressively how unscientific public narratives of obesity cause weight stigma and stimulates discrimination of obese people. Consequently, the statement calls for strong policies and legislation to prevent weight-bas...

Brief summary: Emont et al. created a cell atlas of human and mouse white adipose tissue, which goes a long way in informing our understanding of the complexity of adipose tissue.Although adipocytes make up the largest proportion of adipose tissue volume, the cellular structure of adipose tissue is far more complex and includes adipose tissue progenitor cells (APCs), fibroblasts, vascular cells and immune cells. We are also beginning to understa...

Brief summary: Genomic information (nuclear, Y-chromosome and mitochondrial DNA data) of 13 Neanderthals from two neighboring caves in Siberia have been analysed to infer their social community organization. The data show greater diversity of maternal lineages, which is best explained by female-biased migration between communities.This study is fascinating as it illustrates what information can be gained with genetic data and analysis beyond the medical ...
