This is a good news story http://www.theregister.co.uk/2011/09/19/gamers_crack_structure_of_aids_protein_in_three_weeks/
A bunch of gamers have untangled the structure of a key protein in the virus that causes AIDS, a mystery that has left scientists stumped for decades.
It took just three weeks for players of online game Foldit to predict an accurate model for the protein – a type of enzyme called a retroviral protease that has a critical role in how the HI virus grows and spreads.
The game Foldit was specially designed to help work out the structure of proteins. It combines computer intelligence with human spatial abilities by asking players to tweak and tug 3D models, a task that computers find hard to do.
This is a very unusual topic for here but its heartening to note that if folks pull together en masse breakthroughs can be made in enormously shortened time frames, this is not the first project of this type but its been a respounding success and with such a painful and tragic disease any success is worth a mention.
