Players of the online game Foldit have been able to determine the optimal structure of a protein that could prove key to the development of antiretroviral drugs to combat diseases like AIDS.

A report from the University of Washington [PDF] outlines how, in just three weeks, Foldit players generated a model for a protein in the Mason-Pfizer monkey virus (M-PMV), responsible for a simian form of AIDS, that was more accurate than multiple computer-generated refinements that have been in development for years.

Foldit players worked together with teammates while competing against other teams to "fold" the highest-scoring 3D model of the protein, usually without any specific knowledge of the underlying biochemistry behind the concept.

After the three-week online competition, researchers found that several of the solutions created by the Foldit players produced better results than all previous approaches, leading to the creation of a final refined model for the protein only a few days later.

"The critical role of Foldit players in the solution of the M-PMV PR structure shows the power of online games to channel human intuition and three-dimensional pattern-matching skills to solve
challenging scientific problems," the researchers wrote.

"Although much attention has recently been given to the potential of crowdsourcing and game playing, this is the first instance that we are aware of in which online gamers solved a longstanding scientific problem."

Despite this success, researchers warned that the game was not always so successful at finding optimal protein models. Since players often make only small changes to the initial models given, players sometimes centered on improved "local minima" that were far from the best possible result.

The Foldit project is separate from Sony and Stanford's Folding@Home project, which uses spare PS3 computing cycles in a fully automated effort to find optimal protein structures.

I think this is amazing

this project was the focus of a (great) session at the recent Serious Play Conference. This AIDS-related breakthrough was one of two they were preparing to publish.



The speaker (Zoran Popovic), went on to talk about their next project, solving the nations problem with learning fractions. He noted there wasn't a lot of research on the learning paths students take through fractions, so their game was design to map these out (and was implementing an idea similar to how Amazon guesses and checks which products to show you on return visits).

Apparently this game is already available to the public, and is called Refraction.



All in all, I was stunned to see these people already doing the things I thought were years off (useful serious games that demonstrate results)



just mentioning all this to say : if you're into educational gaming innovations - you should look into the Serious Play Conference.
