Scientists at Japan's National Defense Medical College have created a universal artificial blood that can be transfused into any patient regardless of their blood type. This breakthrough uses liposomes to carry hemoglobin and platelets, mimicking natural oxygen transport and clotting without the risk of immune rejection. Unlike real blood, which requires refrigeration and expires in weeks, this synthetic version is shelf-stable at room temperature for over a year, making it a game-changer for emergency transport and remote disaster zones where blood typing isn't possible.
