True, we are self-interested creatures capable of destroying the habitats that support us as we each focus on getting our share of the global commons before others beat us to it. Yet Homo sapiens could never have populated the planet and mastered complex technologies and organizational forms had nature not also made us sensitive to one another's regard. Both field studies and laboratory experiments depict humans as willing to cooperate when convinced that others are doing the same and that at least some will incur costs to sanction cheating. On page 613 in this issue, Janssen et al. (1) show that communication among members of a group is key to establishing cooperation and using punishment effectively, and on page 617, Boyd et al. (2) provide a model of how signaling (a stylized kind of communication) could have allowed punishment and cooperation to evolve. *  Cooperation and Punishment, Louis Putterman, 2010/04/30, DOI: 10.1126/science.1189969, Science Vol. 328. no. 5978, pp. 578 - 579  http://dx.doi.org/10.1126/science.1189969 ------------------------------ Disrupted Networks: From Physics to Climate Change , World Scientific Publishing Company Summary: This book provides a lens through which modern society is shown to depend on complex networks for its stability. One way to achieve this understanding is through the development of a new kind of science, one that is not explicitly dependent on the traditional disciplines of biology, economics, physics, sociology and so on; a science of networks. This text reviews, in non-mathematical language, what we know about the development of science in the twenty-first century and how that knowledge influences our world.
