It's actually a link to an article about a medical issue. However, it has implications for criminal cases. I suppose crime relates more closely to politics than skepticism or conversation, so I'm placing it here.
Feel free to move it if I've made the wrong choice.
In any event -- this article is so bizzare. If this can actually happen, it could really mess up DNA identifications.
I imagine it wouldn't happen often...but if it did in terms of a criminal case can you imagine the chaos it would create?
And now that it's known that such things can happen -- could sleazy lawyers use this as an argument to get DNA identifications thrown out?
It appears to apply to bone marrow transplants. The bone marrow is where red blood cells are made, so it makes sense that blood would be changed. Anyway, it shouldn't be much influence on trials and such because so few people have had marrow transplants and the donors are often from far away, so couldn't have committed the crime. Still, something to consider. But it won't be long before people's DNA can be tweaked and someone could have changes made post-crime that would get them off. 8-<
