Here is a quote from SlashDot "NewScientist is reporting that Welsh boy Rhys Evans has been cured of the fatal severe combined immunodeficiency ("bubble boy") disease. The medical team, lead by Adrian Thrasher, was able to take the stem cells that give rise to immune cells from his bone marrow and add a normal copy of the gene to the stem cell using a retro virus. Seven months after treatment, Rhys was cured."
Wow, this is so cool.
I don't know what else to say.
