Abstract: Nature. 2019 Mar;567(7747):234–238.In brief: In this article, the authors present evidence that the murine epiphyseal growth plate develops a postnatal stem cell niche with monoclonal properties, that are able to self-renew. They thereby challenge the concept of a continous depletion of progenitor cells as a limiting factor for bone growth.<p class="abste...

Brief summary: Using in-depth multi-omics analyses of human type 1 diabetes (T1D) samples, the authors profiled gut microbial functional and metabolic alterations. The T1D microbiota showed decreased butyrate production and bile acid metabolism and increased lipopolysaccharide (LPS) biosynthesis. Fecal microbiota transplantation in animal models proved that T1D gut microflora is a causative factor in the regulation of glucose metabolism.The etiology of T...

Brief Summary: This study marks significant progress in understanding ancient genomes, particularly in deciphering chromosomal sex, aneuploidies, and their broader historical and societal implications. By extracting and analyzing DNA from ancient remains, researchers have uncovered new insights into disorders of sex development (DSDs) that were previously inaccessible. These authors pioneered a computational method to identify sex chromosomal aneuploidies. This approach indepe...
