nice, in their Acknowledgements, pag.18.

yes, but google does not share its log files!

Google published a Nature paper out of it. AFAIK the data (google queries) on which that research is based is kept well secret. Therefore it is not possible to validate what they did. Science cannot be based on secret data, and the journal Nature in this case published an advertising ("how awesome is google"), not a scientific paper ("these are the data, this is our method, check out our conclusions").

As they athors here say, approaches from closed sources like google limit a lot the efficiency of this kind of approach. So they choose a free software thinking: wikipedia because the data is public + their software is free software. Good work.

the real possibility to have genetically modified athletes in the future (via the same principle of targeted virus infection) is discussed in Nature (pay per view #@!) http://www.nature.com/nature/journal/v487/n7407/full/487297a.html

This is a manifesto of a society culturally behind. It can work for a tribe, not for the nation that wants to lead the world. Living in group requires giving up the right of personal violence and revenge, in favor of an organized law enforcement and justice system. I learnt that at school, didn't you? this text describes the old far west. Please, let's end with it! Your ideology is killing people. (because ideologies do kill)
