Health professionals, engineers, researchers, developers, marketers, business people, students, entrepreneurs, anyone interested in questions of sexuality? You're invited to sign up to participate in SexTechLab. This is a 50-hour challenge, during which you'll collaborate with other talented participants to help innovate around sexuality. You'll be challenged to come up with a great idea, form a start-up team, and pitch the idea to a jury -- and win prizes! Themes on which to base your idea are The Encounter, Love, Sexuality, and Gender and Health.
