Join us this week as we walk through the science of HIV and AIDS, as depicted in the award-winning flick "Dallas Buyers Club!" We discuss Matty Mac's symptoms, the progression and life-cycle of HIV, and feature a special interview with Sean's sibling, Gabby Crosson, to get their take on Jared Leto's performance!

We'll be coming at you again in two weeks with James Franco's quest to cure neurological diseases in "Rise of the Planet of the Apes!" Get us questions @reelsciencecast, on Facebook, or at [email protected]!
