Submission + - Blood groups 'can be converted'

mrneutron2004 writes: When someone is in need of blood, there sometimes isn't enough available. Motor vehicle accidents and major trauma can damage vital organs, leading to blood loss, and then shock. If blood can be given in a timely manner, it can give doctors the time they need to perform surgery and correct internal injuries. However, finding the right blood type to avoid rejection is a problem, thus patients are given 0- a universal blood type. With more blood available using this new technique, countless lives may be saved. For those against blood transfusions (Jehovah Witnesses), they are even working on "fake" blood. Scientists have developed a way of converting one blood group into another. The technique potentially enables blood from groups A, B and AB to be converted into group O negative, which can be safely transplanted into any patient. http://www.fastsilicon.com/latest-news/blood-group s-can-be-converted.html?Itemid=60
