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 mean, as much as I dislike making circumcision mainstream, if it saves lives in a continent where AIDS is at full epidemic strength, it's a no-brainer. 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.
There's been talk for a while now about the troubles facing the aviation industry, troubles that don't stir pity in my heart for them in the slightest. The aviation industry is one of the worst contributors to climate change, so much so that merely taking a return flight can add a ton of carbon to your personal emissions per year. Our own environment minister's largest source of emissions last year were plane flights.
