I was just reading through this really encouraging sum-up of progress on preventing and treating HIV: http://old.news.yahoo.com/s/afp/20110720/hl_afp/healthaids On the whole, it's great news.

I just hope we can move past it with more advanced methods at some point in the future. However, the bit that caught my attention was the ongoing (though low-level) debate as to whether a practical cure for HIV will ever be possible.

Our own environment minister's largest source of emissions last year were plane flights.
