Via my friend, Gamers have apparently helped scientists to achieve a significant research breakthrough in the struggle to cure AIDS. Read the full article for all the details, but apparently a group of gamers playing Foldit was able to decrypt the structure of an AIDS-like virus' enzyme in three weeks, something that has held scientists back for nearly a decade.
It's always exciting to hear stuff like this, because it validates one of my favorite hobbies. Kids, next time your mom tells you to put away the video games, just tell her that you're working on a cure for all the world's diseases. ;)
