Video games have a way of catching a player's attention, and it's no less true with science-based video games. EteRNA, a game developed in January 2011 by researchers at Stanford University and Carnegie Mellon University, allows players to design new RNAs, the most promising of which are then synthesized in Stanford labs, says Wired Science's Brendan Koerner. The game now has more than 38,000 registered users.
