PMID: 34668586, doi: 10.1111/cen.14614.Brief Summary: This retrospective case-control study used data from the international DSD registry to investigate the long-term outcomes of males born small for gestational age (SGA) with hypospadias/DSD. A large cohort of 179 boys (115 males born SGA; 64 appropriate for gestational age) was investigated for growt...

To read the full abstract: Nature 2020;579:111–117.In brief: In large fracture calluses, skeletal progenitors activate the chondrogenesis program, whereas in smaller calluses, direct osteogenesis is the preferred path. Here, the authors show that lipid availability determines whether skeletal stem cells repair a fracture through endochondral bone formation or direct ossificati...

To read the full abstract: Trends in Ecology & Evolution, 2018. 33 (8); 582–594.This opinion piece argues that Homo sapiens evolved within interlinked groups living across Africa, and not in a single region of East Africa. Millennia of separation gave rise to diversity of human forms, and a complex mix of archaic and modern features in different places and...
