Why are asses sort of heart-shaped? How do animals decide on their hook-up partners? And why are you still, despite your best judgment, attracted to fill-in-their-name-here?! University of Portland's biology professors will answer your most puzzling sex- and reproduction-related questions at this pre-Valentine's Day shindig, which should appeal to the nerdiest and horniest among us. Your $10 donation will support University of Portland students, and attendees can grab a free mocktail before they learn about the birds and the bees. by Lindsay Costello
