If it’s late Winter that can only mean it’s time for the Conference on Retroviruses and Opportunistic Infections again. CROI is probably the most important yearly conference covering advances in HIV research. You can catch the conference (most of it anyway), at home, on your couch, thanks to the wonders of webcasts over the Internet. This includes the pre-conference workshops. They are sort of a review of where things stand in HIV related research that will bring you up to speed on recent advances and ongoing challenges. Catch it all at webcasts.retroconference.org.
