Via Salon.com: ‘On World AIDS Day, good news, however abstract, is more than welcome. That news came in the form of a new study published in the Proceedings of the National Academy of Science which has found that HIV, the human immunodeficiency virus, is actually evolving in a way that makes it harder for the virus to cause AIDS. The research studied 2,000 women in Botswana and South Africa, two countries which have been hit hard by the epidemic.

…The positive findings are accompanied by the news that the number of people receiving treatment has now exceeded the number of newly infected people, which is an important tipping point in terms of fighting the disease.’
