I've seen people change their name, hair color, eye color, even in some cases their height. However, as reported in the The New England Journal of Medicine today, a 9 year old girl has switched her blood type. This is a first in recorded human history and a major finding which encourages future transplant and stem cell research. Granted the switch was from O- to O+ it's still a first and has allowed the girl to better tolerate her transplanted liver. The very basic theory is that stem cells from the donor's liver were able to colonize the child's bone marrow and effectively made the switch from O- to O+.
In other science news US researchers are one step closer to creating artificial life after having successfully made from scratch the DNA of a bacteria. They're calling it "Mycoplasma laboratorium". The great thing about the Mycoplasma genus is that it is very simple lacking even a cell wall. However, also included in this genus are Mycoplasma pneumoniae (which causes atypical pneumonia) and Mycoplasma genitalium (which may be associated with pelvic inflammatory diseases and cancer).

Changing bloodtype?! That is pretty cool. I'm curious about the changing height (no, not because I want to do it...) The only place I saw that done was with Ethan Hawke on GATTACA, but I'm pretty sure it wasn't real- just a movie. Do you have references for that?
