Gamers Beat Algorithms At Finding Protein Structures

jamie writes "Researchers have turned the biochemical challenge of figuring out protein folding structures into a computer game. The best players can beat a computerized algorithm by rapidly recognizing problems that the computer can't fix. From the article: 'By tracing the actions of the best players, the authors were able to figure out how the humans' excellent pattern recognition abilities gave them an edge over the computer. For example, people were very good about detecting a hydrophobic amino acid when it stuck out from the protein's surface, instead of being buried internally, and they were willing to rearrange the structure's internals in order to tuck the offending amino acid back inside. Those sorts of extensive rearrangements were beyond Rosetta's abilities, since the energy changes involved in the transitions are so large.'"

It's fantastic to have validation that humans are still excellent pattern recognition engines compared even to very modern algorithms and powerful computers.

Foldit had the great insight to take you to an algorithmically close starting place and let you complete the final adjustments - in that way the algorithm itself is as much a part of the team as the detail or adjustment members they were talking about.

    I wonder how many other ideas can be so easily brought to a place close enough that a human can recognize patterns enough to be of use in a final solution. I look forward to seeing what astronomers come up with...

However, pattern recognition is implemented right at hardware (wetware?) level, so of course it's ridiculously effective.

  25. Can someone explain? by Anonymous Coward · · Score: 0

    What is the point of foldit? I have played the game, and indeed RTFA, however it's not clear to me what you are achieving by playing the game.
    Is it just confirming that humans can fold better than computers? Or does the successful folds you make in some way matter at all?
    If it's just the former, then it seems like a pretty colossal waste of time.

  26. Wish we had used this in class. by Anonymous Coward · · Score: 1, Interesting

    Good lord. Why couldn't we have used this in Biochemistry class?? Just last year they had us using this horrid program called 'O' as the official modeling software for one of our sections. There were some specific questions that had to be answered from the 'O' perspective, but everyone was switching back and forth to jMol so that we could actually see something informative..

    I know I know, when you were young molecular modeling meant hand-crafted stick figures. I'll get off your lawn now!

    So any word on if Foldit players now have a finite Erdos number?

  28. The title is WRONG by the+gnat · · Score: 1

    The article is horribly misleading - it suggests that the FoldIt users came up with better structures completely on their own. What they were actually doing was improving the automatic structure predictions. If you actually read the Nature article, it shows comparisons of the initial model, final model, and experimental structures. The initial model has the overall fold correct, but with some gross errors which the FoldIt players corrected, leading to an even better model. This is still an impressive result, but it simply doesn't mean what Ars Technica says it means. The author sort of admits that Rosetta helped at the end, but it sounds completely ignorant of how difficult it is to even guess the overall fold correctly. I'm wondering if the writer even bothered to read the original article or just read the PR material.

  29. WOW should involve protein sequencing by Raghu13 · · Score: 1

    People literally spend days playing WOW and other mmorpgs. It would be nice if they can integrate some folding, SETI problem statements into the game. May be we can find aliens and the cure the fun way.
