Call for papers: Special issue of JSSC on Complex Systems and Sports, 2011/12/31 ASSYSTComplexity One of the main goals of the ASSYST Coordination Action is to promote Complex Systems for Socially Intelligent ICT (COSI-ICT) and, more generally, Complex Systems (CS) Science in Europe and Worldwide. We do this by communicating widely with scientists, policy makers, and business people, and by...

Animal survival depends on the ability to analyze the environment and act on it: escape predators, find food, select a mate. Understanding how the brain achieves this is one of the most fascinating and challenging problems in neuroscience. What sequence of steps converts sensory cues into behavior? In other words, how does the brain...

Keeping track of an extended network of Facebook friends, Twitter followers, and LinkedIn connections—not to mention those old-fashioned face-to-face relationships with neighbors and office mates—can certainly feel like a mental challenge. But does having a larger, more complex social network actually change the brain? A new study with macaques suggests it...

It has been suggested that variation in brain structure correlates with the sizes of individuals’ social networks. Whether variation in social network size causes variation in brain structure, however, is unknown. To address this question, we neuroimaged 23 monkeys that had been living in social groups set to different sizes. Subject comparison revealed that living in larger groups caused...

(…) some hints about the sequence of events that led to the evolution of human social systems are emerging. The latest evidence comes from Shultz et al.1, who (…) trace the evolution of complex sociality within the order Primates. Their data provide a strong foundation for modelling the origins of hominid mating systems by constraining the range of likely trajectories of social...

(…) This supports suggestions that social living may arise because of increased predation risk associated with diurnal activity. Sociality based on loose aggregation is followed by a second shift to stable or bonded groups. This structuring facilitates the evolution of cooperative behaviours5 and may provide the scaffold for other distinctive anthropoid traits including coalition formation,...

The eurozone, like the rest of the world economy, is a complex networked system. That gives it properties economists rarely consider but which could help us understand the current...

What drives our desire to behave morally? Neuroeconomist Paul Zak shows why he believes oxytocin (he calls it "the moral molecule") is responsible for trust, empathy and other feelings that help build a stable...
