Hum Posted September 19, 2011 Share Posted September 19, 2011 In just three weeks, online gamers deciphered the structure of a retrovirus protein that has stumped scientists for over a decade, and a study out Sunday says their breakthrough opens doors for a new AIDS drug design. The protein, called a protease, plays a critical role in how some viruses, including HIV, multiply. Intensive research has been underway to find AIDS drugs that can deactivate proteases, but scientists were hampered by their inability to crack the enzyme's structure. Looking for a solution, researchers at the University of Washington turned to Foldit, a program created by the university a few years ago that transforms problems of science into competitive computer games, and challenged players to use their three-dimensional problem-solving skills to build accurate models of the protein. Within days, the gamers generated models good enough for the researchers to refine into an accurate portrayal of the enzyme's structure. What's more, the scientists identified parts of the molecule that are likely targets for drugs to block the enzyme. "These features provide opportunities for the design of antiretroviral drugs, including anti-HIV drugs," the authors wrote. Proteins are made up of long chains of amino acids that fold into complex shapes, but their structures are difficult even for computers to predict. "We wanted to see if human intuition could succeed where automated methods had failed," said Firas Khatib, a lead author of the study, published in the journal Nature Structural & Molecular Biology. The researchers were hopeful that their finding would open further possibilities of crowd-sourcing and online game-playing in scientific discovery. "The ingenuity of game players is a formidable force that, if properly directed, can be used to solve a wide range of scientific problems," Khatib said. Seth Cooper, a co-creator of Foldit, added, "People have spatial reasoning skills, something computers are not yet good at. Games provide a framework for bringing together the strengths of computers and humans. The results in this week's paper show that gaming, science and computation can be combined to make advances that were not possible before." source Link to comment Share on other sites More sharing options...

Shadrack Posted September 19, 2011 Share Posted September 19, 2011 I wish the article would go into more detail on how the game was constructed to collect data from gamers, why they think the results are meaningful, and how an automated approach was fruitless.

Dotdot Posted September 19, 2011 Share Posted September 19, 2011 I wish the article would go into more detail on how the game was constructed to collect data from gamers, why they think the results are meaningful, and how an automated approach was fruitless. my thoughts exactly. i mean are we using downtime in PS3 cells to calculate and if so why wasnt this able to be done by one of the many supercomputers, or does the sheer volume of online gamers allow for sheer processing power required. or as you suggest, it collected via a game of some sorts. if so what was its objectives and parameters and how exactly did this relate to decoding this puzzle Link to comment Share on other sites More sharing options...

xendrome Posted September 19, 2011 Share Posted September 19, 2011 Funny part is... Gamers didn't do anything... The real story is "Playstation 3 systems use distributed computing to Crack Puzzle in AIDS Research that Stumped Scientists for Years" Gamers really didn't do anything.. plus.. I'm PRETTY sure there are PC based clients.. oh wait.. there are - http://fold.it/ Anyone brave enough to find the stats for this specific project and see if it shows client hardware/OS broken down... My guess is PC/MAC/Linux clients may outnumber PS3 Link to comment Share on other sites More sharing options...
