Today is World AIDS Day, and people are out on College Walk to tell you about it. The Student Global AIDS Campaign have set up a communal art project/fundraiser, to represent the entire HIV virus genome out of tiles. The virus has almost 10,000 base pairs, so they’re aiming to create a representation using that many tiles. You and a date can stop by Low Steps today and tomorrow to donate three tiles (definitely not a divisor of 10,000 but who’s counting) to the project at a cost of $1.

They’ve also planned a benefit event tonight, featuring our own Jeffery Sachs, founder and executive director of AIDS International Jesus Aguis, and live music and dance performances.
