The two atlases map gene expression and availability as cells differentiate into different cell types and tissues. UW Medicine researchers at the Brotman Baty Institute in Seattle have created two cell atlases that track gene expression and chromatin accessibility during the development of human cell types and tissues. An artist’s […]

Timeline of early eukaryotic evolution unveiled the mitochondrial acquisition occurred in a scenario of increasing complexity. Credit: Utrecht University, IRB Barcelona By analyzing duplicates of thousands of genes, researchers have reconstructed the evolutionary events leading to the creation of eukaryotic cells, the precursors to virtually all life you can see […]

An artistic reconstruction of ‘Southern European’ Vikings emphasizing the foreign gene flow into Viking Age Scandinavia detected in the study. Credit: Jim Lyngvild In the popular imagination, Vikings were fearsome blonde-haired warriors from Scandinavia who used longboats to carry out raids across Europe in a brief but bloody reign of […]

Evolutionary Anthropology Neanderthals have adopted male sex chromosome from modern humans. In 1997, the very first Neanderthal DNA sequence — just a small part of the mitochondrial genome — was determined from an […]

Tea There Are Many More Angelfishes in the Sea Why do some fish species form hybrids while others don’t? In attempting to answer this question, new research has uncovered that angelfish are the chief […]

Losing weight could prevent or even reverse diabetes, according to late breaking research presented today at ESC Congress 2020.1 In 2019, approximately 463 million people worldwide had diabetes, of which the vast majority (around 90%) was type 2 diabetes.2 Diabetes doubles the risk of coronary heart disease, stroke, and death from […]

Mice lacking CNOT3 in pancreatic beta cells have fewer insulin-producing cells, leading to diabetes. Credit: OIST A protein that’s common throughout the body plays a key role in regulating glucose levels, says new research conducted in the Cell Signal Unit at the Okinawa Institute of Science and Technology Graduate University […]

International scientists and Ngātiwai, a Māori tribe, teamed up to sequence the genome of a rare reptile, the tuatara, uncovering some unique aspects of the tuatara’s evolution. The genome sequence will enable comparative studies to better understand the evolution of the tuatara and its distant relatives: other reptiles, birds, and […]
