On the night of October 15, the usually quiet Wiegand Gym in the University Center was filled with the sounds of hip-hop, techno, and 80s music, as Carnegie Mellon's Dance Marathon began. Now in its third year, Dance Marathon is a 12-hour fundraiser for the St. Jude's Children's Research Hospital in Pittsburgh. Proceeds go to the hospital's research and treatment program for children suffering from life-threatening diseases, such as cancer.
