This really is a bit beyond the admittedly vague lines of Ruminations, but I couldn't resist. The Economist has a big article about a recent big international conference on a big problem: AIDS. It turns out that after more than two decades of pouring zillions of $ into research about this horrible affliction, humanity has figured out how to stop HIV from becoming AIDS, but still has no clue about the AIDS itself. Given the ever-rising cost of preventing millions of HIV bearers from tipping over into lethal AIDS, this is a big problem.
In the meantime, however, a number of preventive measures appear ever more useful. We all know about condoms, that's not new, but apparently there are two other measures that are quite effective. The first is monogamy (surprise!). And the second is circumcision. Heh.
