Wow, finally an advance that helps people 🙂  I donate blood as often as I am able and know that there is always a shortage.  The largest portion of the shortage is always O.  O, you know… the “universal” blood type.  Now we can make O from the other types is awesome!  This is going to save many many lives….


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, which can be safely transplanted into any patient.

The method, which makes use of newly discovered enzymes, may help relieve shortages of blood for transfusions.

The work, led by the University of Copenhagen, is reported in the journal Nature Biotechnology.
