Cell nucleus illustration. University of California Riverside-led study identifies how blood stem cells maintain their fate. Understanding the molecular mechanisms that specify and maintain the identities of the human body’s more than 200 cell types is perhaps one of the most fundamental problems in molecular and cellular biology, with major implications for human disease management. … Read more
New research from a European collaboration paves the way for innovative strategies to fight atherosclerosis. A new research study shows the existence of a connection between atherosclerotic plaques and the central nervous system. This previously unknown “circuit” involves three systemically acting tissues, the immune system, the nervous system, and the cardiovascular system. This crosstalk is … Read more

Princeton University researchers reported in a new study that unless greenhouse gas emissions are curbed, marine biodiversity may be on track to plummet to levels not seen since the extinction of the dinosaurs. The scientists modeled future marine biodiversity under projected climate scenarios and found that species such as dolphinfish (shown) would be imperiled as … Read more
