Folding@Home 2.0 - An Online Protein Folding Game

a boy named woo writes "Tired of justifying your gaming addiction? Now you can really help accomplish something while you play... thanks to Howard Hughes Medical Institute researcher David Baker at the University of Washington." In collaboration with others, Baker has designed a game, called "Foldit," with a practical outcome: players manipulate on-screen images of protein chains and attempt to predict their folding patterns. From the article: "'Our main goal was to make sure that anyone could do it, even if they didn't know what biochemistry or protein folding was,' says [co-creator Zoran] Popovic. At the moment, the game only uses proteins whose three-dimensional structures have been solved by researchers. But, says Popovic, 'soon we'll be introducing puzzles for which we don't know the solution.'"

  27. this could be the next big thing by rritterson · · Score: 5, Informative

    I work in a protein engineering/structure lab that has strong connections to the Baker lab, both in people and in scientific collaboration. The biggest project to come out the Baker lab is a protein structural modeling, simulation and prediction suite known as ROSETTA. While I'll gloss over some of the nitty-gritty about the methodology, suffice it to say that ROSETTA, through a combination of knowledge based and physics based modeling, has knocked the pants off of just about every other program out there used to simulate, design, and fold proteins. (Quantum-based physics models can be much better than ROSETTA, at the expense of a few extra superclusters and months of simulation time).

    I no longer work as a ROSETTA developer or the "protein folding problem", but many of my lab mates do. They struggle with ROSETTA sometimes, as it comes close to predicting the real structure of a protein, and then falls away and wanders into another structure far from reality. If only it could 'see' the best structure when it came close!

    The problem can be analogized with surveying a landscape. Imagine every square feet of dirt you can see is one possible protein structure, and you want to find the lowest elevation square foot. For a human, the visual search process is fairly quick and rapid. You can see a few hills out in the distance, but a much lower valley on the other side, where the land is lowest. It takes only a few seconds. On the other hand,a computer with no prior knowledge of the landscape can take a very long time to find that global minimum. The computer essentially has to drop a ball on the landscape and watch where it rolls, then pick it up, put it somewhere else and watch again (Physics and computer modelers forgive me!). It may never pick the right starting point to get over that far away hill.

    Perhaps the brain can be as good at finding great protein structures as we are at finding lowest elevation points. Perhaps intuition about how a protein 'should' look can get us places a computer program never can without a ton of time and power. That's what this game is all about. The baker lab has done a fantastic job of turning a very hard scientific problem into a competitive game that is simultaneously fun, provides possible scientific information, and represents something of a human experiment on how our brains work.

    This could be the next leap forward if it turns out some people have an innate knack for folding. It should be interesting to watch.

    Seriously: I know that's a bit subjective, but I (and literally millions of others) disagree with that. I run BOINC on my computers because it does *not* suck. I run several projects on each, ensuring that when/if one has a server outage or workunit lull, my BOINC clients are doing something useful for someone *else*.

    Perhaps you've never heard of or used the account managers BAM or GridRepublic; they make managing projects and client computers a breeze. They're easy to use but quite flexible.

    I wholeheartedly think their functionality should have been built into BOINC from the get-go, but perhaps the authors of BOINC (the Berkeley team that does seti@home) omitted it intentionally because *someone* has to run the software and they didn't want to be the ones.

    Folding@home is a big and well-funded project that doesn't benefit from the middleware that is BOINC, but they also reap no benefits from the network effect that such a wide userbase offers.

    So no, I don't think BOINC sucks anything like "really really bad".

I'm curious about your opinion of the Tanpaku project's approach, which seems to be similar to that of Folding@home and rather "classical". They use (what seems to be) a hybrid molecular dynamics algorithm that greatly reduces 1) the problem complexity, i.e. the number of relevant particles and thus particle-particle interactions, and 2) the timeslices needed to calculate those interactions. Is the gradient descent method a good trade-off of reliability / result precision for computational efficiency?

    The problem can be analogized with surveying a landscape. ...
    (Physics and computer modelers forgive me!) (Ouch.) You're describing gradient descent, which requires a coherent solution space and a differentiable heuristic for "descending" through it to the most optimal solution subject to the constraints of the function being investigated.

    The computer essentially has to drop a ball on the landscape and watch where it rolls, then pick it up, put it somewhere else and watch again So your search algorithm uses a probabilistic, shotgun/Battleship!-style approach to carpet-bomb the solution space, or perhaps (guided by some heuristic) just the "interesting" parts of it? I suppose this is niggling, but is there some reason not to use a momentum factor, or try several, since that's job-level parallelism (which you have with BOINC)?

    It may never pick the right starting point to get over that far away hill. With a momentum factor, it needn't. The price paid is a loss of precision in the descent algorithm, which might miss an optimal solution if that solution were only slightly more optimal than nearby solutions. To further abuse your analogy, the ball might roll right over the lowest point if it either didn't fit or is going so fast when it gets there that it rolls right up into local minimum with steeper inside slope.

    Perhaps intuition about how a protein 'should' look can get us places a computer program never can without a ton of time and power. I'm quite skeptical. This is GalaxyZoo, except you have to make your own galaxies based on intuition about how they "should" look (and constrained to the relevant laws by the software).
