Blood supplies often run low. There are different blood types and a person with Type A cannot receive Type B in a transfusion, for example. However, anyone can receive Type O – it is regarded as a universal blood group. Now, researchers may have found a way to convert any type of red blood cell into Type O.
Speaking at the American Chemical Society, researchers from the University of British Columbia, Canada, reported that an enzyme (a molecule that assists chemical reactions) found in the gut can do this conversion in a safe, efficient and economical manner.
