Scientists have found bacteria that can convert blood types A, B and AB into type O which can be given to anybody without eliciting an immune response.
Blood types A, B and AB have sugar molecules that attach themselves to the blood cells. When the wrong blood type is introduced, the body detects the incorrect sugar molecules and mounts a deadly attack. Type O however has no sugar molecules therefor nothing to detect which is why there is such a huge demand and shortage for it. The bacteria they found clips away the extra sugar molecules in the other 3 types converting them into type O.
They're currently refining the process in hopes of relieving the massive blood shortages in developing countries and during natural disasters. This couldn't come any sooner.
That bloody bear bag is so morbid yet cute. To this day, I'm not even sure what my blood type is but if all goes well, I won't need to. . . according to this article.
This is so great, but that bag...
