Before revision:  Most real-world networks show a number of properties, such as small-worldness or scale-free degree distribution, which are rather general features of networks  from molecules to the society . Based on extensive analogies I propose that the existing findings and methodology  enable us to detect active centres in cells,  social networks and ecosystems.
