You may wish to take note of your immediate surroundings, as this may end up being one of those "where were you when _____?" dates. Doctors in Germany have, evidently, cured a man of HIV.
The technique? In brief, they obliterated his entire immune system with chemotherapy, they replaced it with a new one using stem cells from a donor who had been born with nigh-total immunity to HIV. It's a radical procedure, which most patients don't survive, but this guy did.
I was in my house, editing a video, incidentally.
