  1. Stepping Away From the Trees For a Look at the Forest, Science Next Article Bookmark and Share

    Summary: In science, an ingenious new tool often triggers a cascade of new insights. In this special section, Science's news reporters and editors mark the end of the current decade by stepping back from weekly reporting to take a broader look at 10 insights that have changed science since the dawn of the new millennium. This survey covers only a small fraction of the decade's scientific advances, of course; many others could have filled these pages.

  2. There's Plenty of Time for Evolution, PNAS Next Article Bookmark and Share

    Abstract: Objections to Darwinian evolution are often based on the time required to carry out the necessary mutations. Seemingly, exponential numbers of mutations are needed. We show that such estimates ignore the effects of natural selection, and that the numbers of necessary mutations are thereby reduced to about K log L, rather than KL, where L is the length of the genomic “word,” and K is the number of possible “letters” that can occupy any position in the word. The required theory makes contact with the theory of radix-exchange sorting in theoretical computer science, and the asymptotic analysis of certain sums that occur there.

  3. Mathematical modeling of evolution. Solved and open problems, Theory in Biosciences Next Article Bookmark and Share

    Excerpt: Evolution is a highly complex multilevel process and mathematical modeling of evolutionary phenomenon requires proper abstraction and radical reduction to essential features. Examples are natural selection, Mendel’s laws of inheritance, optimization by mutation and selection, and neutral evolution. An attempt is made to describe the roots of evolutionary theory in mathematical terms. (...)

  4. Work: The New Face of Retirement, Knowledge@Wharton Next Article Bookmark and Share

    Excerpt: In this special report, we take a detailed look at retirement in the 21st century from a global perspective. One article explores the reasons why people are working longer than their parents did and viewing the later decades of life as more than an endless weekend. Another article describes the crisis of public and private pension plans and the painful attempts to keep them solvent. In a third article, we examine the role of older workers in the workplace and the myths that make some employers wary of hiring them. Finally, we offer advice on how to prepare financially and vocationally for life in the later decades.

  5. Halla Tomasdottir: A feminine response to Iceland's financial crash, TED.com Next Article Bookmark and Share

    About this talk: Halla Tomasdottir managed to take her company Audur Capital through the eye of the financial storm in Iceland by applying 5 traditionally "feminine" values to financial services. At TEDWomen, she talks about these values and the importance of balance.

  6. Are biological systems poised at criticality?, arXiv Next Article Bookmark and Share

    Abstract: Many of life's most fascinating phenomena emerge from interactions among many elements--many amino acids determine the structure of a single protein, many genes determine the fate of a cell, many neurons are involved in shaping our thoughts and memories. Physicists have long hoped that these collective behaviors could be described using the ideas and methods of statistical mechanics. In the past few years, new, larger scale experiments have made it possible to construct statistical mechanics models of biological systems directly from real data. We review the surprising successes of this "inverse" approach, using examples form families of proteins, networks of neurons, and flocks of birds. Remarkably, in all these cases the models that emerge from the data are poised at a very special point in their parameter space--a critical point. This suggests there may be some deeper theoretical principle behind the behavior of these diverse systems.

    1. Statistical Mechanics of Horizontal Gene Transfer in Evolutionary Ecology, arXiv Next Article Bookmark and Share

      Abstract: The biological world, especially its majority microbial component, is strongly interacting and may be dominated by collective effects. In this review, we provide a brief introduction for statistical physicists of the way in which living cells communicate genetically through transferred genes, as well as the ways in which they can reorganize their genomes in response to environmental pressure. We discuss how genome evolution can be thought of as related to the physical phenomenon of annealing, and describe the sense in which genomes can be said to exhibit an analogue of information entropy. As a direct application of these ideas, we analyze the variation with ocean depth of transposons in marine microbial genomes, predicting trends that are consistent with recent observations using metagenomic surveys.

  7. Google Opens Books to New Cultural Studies, Science Next Article Bookmark and Share

    Summary: Mathematicians have used Google Books, the company's ambitious"and controversial"project to digitally scan every page of every book ever published, to analyze the growth, change, and decline of published words over the centuries. The first explorations of the Google Books data are now on display in a study published online this week by Science. The researchers have revealed 500,000 English words missed by all dictionaries, tracked the rise and fall of ideologies and famous people, and, perhaps most provocatively, identified possible cases of political suppression unknown to historians.

  8. Exploring Links to Improve Health, Science Next Article Bookmark and Share

    Summary:
    Offering a thorough introduction to the major theories, methods, models, and findings of research on social networks, Valente explores their current and potential applications to medicine and public health.

  9. Epidemic prediction and control in clustered populations, Journal of Theoretical Biology Next Article Bookmark and Share

    Excerpt: There has been much recent interest in modelling epidemics on networks, particularly in the presence of substantial clustering. Here, we develop pairwise methods to answer questions that are often addressed using epidemic models, in particular: on the basis of potential observations early in an outbreak, what can be predicted about the epidemic outcomes and the levels of intervention necessary to control the epidemic?

  10. Preface: Is Logic Universal?, LOGICA UNIVERSALIS Next Article Bookmark and Share

    Excerpt: The authors have tried to answer the following questions:
    1. Do all human beings have the same capacity of reasoning? Do men, women, children, Papuans, yuppies, reason in the same way?
    2. Does reasoning evolve? Did human beings reason in the same way two centuries ago? In the future will human beings reason in the same way? Are computers changing our way of reasoning? Is a mathematical proof independent of time and culture?
    3. Do we reason in different ways depending on the situation? Do we use the same logic for everyday life, in physics, and in questions to do with the economy?
    4. Do the different systems of logic reflect the diversity of reasoning?
    5. Is there any absolute true way of reasoning?

  11. Static versus dynamic topology of complex communications network during organizational crisis, Complexity Next Article Bookmark and Share

    Abstract: The significance of temporal changes in the topology of organizational communication networks during a crisis is studied using static and dynamic social network analysis (SNA). In static SNA, the network of interactions made during an entire data collection period is studied. For dynamic SNA, shorter segments of network data are used in the analysis. Using measures of degree centrality and core-periphery analysis, the prominence of actors is characterized and compared in the aggregate network (i.e., using static topology) and in daily networks (i.e., using dynamic topology) of a complex email network in a large organization during crisis. We show that while static typology cannot capture the network behavior completely, there are particular situations where the additional description provided by dynamic analysis is not significant. The limitations of dynamic topological SNA are discussed and we stress the importance of associating function with network structure in moving towards a more informative dynamical description.

  12. Sex Determination in the Social Amoeba Dictyostelium discoideum, Science Next Article Bookmark and Share

    Abstract: The genetics of sex determination remain mysterious in many organisms, including some that are otherwise well studied. Here we report the discovery and analysis of the mating-type locus of the model organism Dictyostelium discoideum. Three forms of a single genetic locus specify this species' three mating types: two versions of the locus are entirely different in sequence, and the third resembles a composite of the other two. Single, unrelated genes are sufficient to determine two of the mating types, whereas homologs of both these genes are required in the composite type. The key genes encode polypeptides that possess no recognizable similarity to established protein families. Sex determination in the social amoebae thus appears to use regulators that are unrelated to any others currently known.

  13. Emerging properties of animal gene regulatory networks, Nature Next Article Bookmark and Share

    Summary: Gene regulatory networks (GRNs) provide system level explanations of developmental and physiological functions in the terms of the genomic regulatory code. Depending on their developmental functions, GRNs differ in their degree of hierarchy, and also in the types of modular sub-circuit of which they are composed, although there is a commonly employed sub-circuit repertoire. Mathematical modelling of some types of GRN sub-circuit has deepened biological understanding of the functions they mediate. The structural organization of various kinds of GRN reflects their roles in the life process, and causally illuminates both developmental and evolutionary process.

  14. Topological Traps Control Flow on Real Networks: The Case of Coordination Failures, PLoS ONE Next Article Bookmark and Share

    Excerpt: We study evolutionary games in real social networks, with a focus on coordination games. We find that populations fail to coordinate in the same behavior for a wide range of parameters, a novel phenomenon not observed in most artificial model networks. We show that this result arises from the relevance of correlations beyond the first neighborhood, in particular from topological traps formed by links between nodes of different degrees in regions with few or no redundant paths.

  15. Evolution of cooperation on adaptively weighted networks, Journal of Theoretical Biology Next Article Bookmark and Share

    Excerpt: Recent studies have explored interactions between evolutionary game dynamics and population structure. Yet most studies so far mainly paid attention to unweighted and static networks. Here we explore evolutionary games played on dynamically weighted networks. [...] Both analytical and numerical results show that such an adaptive weight adjustment mechanism dramatically promotes evolution of cooperation.

    1. Evolution of cooperation mediated by limiting resources: Connecting resource based models and evolutionary game theory, Journal of Theoretical Biology Next Article Bookmark and Share

      Excerpt: Recent studies have shown that constraints on available resources may play an important role in the evolution of cooperation, especially when individuals do not posses the capacity to recognize other individuals, memory or other developed abilities, as it is the case of most unicellular organisms, algae or even plants. We analyze the evolution of cooperation in the case of a limiting resource which is necessary for reproduction and survival.

  16. Irrational decision-making in an amoeboid organism: transitivity and context-dependent preferences, Proc. R. Soc. B Next Article Bookmark and Share

    Excerpt: Most models of animal foraging and consumer choice assume that individuals make choices based on the absolute value of items and are therefore ‘economically rational’. However, frequent violations of rationality by animals, including humans, suggest that animals use comparative valuation rules. Are comparative valuation strategies a consequence of the way brains process information, or are they an intrinsic feature of biological decision-making? [...] he discovery of comparative valuation rules in a unicellular organism suggests that comparative valuation rules are ubiquitous, if not universal, among biological decision makers.

  17. Topological stability criteria for synchronized coupled systems of non-identical oscillators, arXiv Next Article Bookmark and Share

    Abstract: Individual dynamical units that are coupled via an interaction network can synchronize spontaneously without central regulation. The propensity to synchronize depends on structural properties of the interaction network. Certain network properties such as heterogeneity and diameter have been studied extensively, however sometimes with conflicting conclusions. This indicates that beside global structural measures of the network also the local and mesoscale configurations of network nodes play a role that cannot be neglected. By constructing a graphical interpretation of Jacobi's signature criterion, we show that synchronization in phase oscillators can only be achieved if the network obeys necessary topological conditions. These analytical results thus identify instabilities that occur in subgraphs on the mesoscale. We then formulate and numerically confirm a conjecture that extends the stability conditions to large scale structures. Finally, we show that the proposed approach can be extended to an adaptive oscillator network, in which the coupling topology co-evolves with the dynamics of the coupled units.

  18. Role-based similarity in directed networks, arXiv Next Article Bookmark and Share

    Abstract: The widespread relevance of increasingly complex networks requires methods to extract meaningful coarse-grained representations of such systems. For undirected graphs, standard community detection methods use criteria largely based on density of connections to provide such representations. We propose a method for grouping nodes in directed networks based on the role of the nodes in the network, understood in terms of patterns of incoming and outgoing flows. The role groupings are obtained through the clustering of a similarity matrix, formed by the distances between feature vectors that contain the number of in and out paths of all lengths for each node. Hence nodes operating in a similar flow environment are grouped together although they may not themselves be densely connected. Our method, which includes a scale factor that reveals robust groupings based on increasingly global structure, provides an alternative criterion to uncover structure in networks where there is an implicit flow transfer in the system. We illustrate its application to a variety of data from ecology, world trade and cellular metabolism.

    1. Crossing in Complexity: Interdisciplinary Application of Physics in Biological and Social Systems, Nova Science Pub Inc Next Article Bookmark and Share

      Summary:
      The developments of theoretical physics in the field of complex systems and emergence has evidenced that many mathematical methods and traditional approaches can migrate towards biological and social systems. The deep physical explanation of such new vitality is simple in its essence and has to be searched in the universality of the emergence processes typical of the Middle Way suggested by the prophetic works of Anderson, Pines and Laughlin. In particular, the systems based on competition and co-operation and their sustainable dependence on the environment have provided a great deal of suggestions for the study of biological and social processes.

    2. Modular Evolution: How Natural Selection Produces Biological Complexity, Cambridge University Press Next Article Bookmark and Share

      Summary:
      Natural selection is more than the survival of the fittest: it is a force engendering higher biological complexity. Presenting a new explanation for the tendency of life to become more complex through evolution, this book offers an introduction to the key debates in evolutionary theory, including the role of genes and sex in evolution, the adaptive reasons for senescence and death and the origin of neural information. The author argues that biological complexity increased through the process of 'modularity transfer': modular phenotypes evolved into new modular information carriers, giving rise to new information systems and higher levels of biological organisation.

    4. Nonlinear Dynamics in Human Behavior, Springer Next Article Bookmark and Share

      Summary:
      Humans engage in a seemingly endless variety of different behaviors, of which some are found across species, while others are conceived of as typically human. Most generally, behavior comes about through the interplay of various constraints " informational, mechanical, neural, metabolic " operating at multiple scales in space and time. Over the years, consensus has grown in the research community that, rather than investigating behavior only from bottom up, it may be also well understood in terms of concepts and laws on the phenomenological level. Such top down approach is rooted in theories of synergetics and self-organization using tools from nonlinear dynamics.

      Summary:
      This book is one of the first to provide a general overview of order and chaos in dynamical astronomy. The progress of the theory of chaos has a profound impact on galactic dynamics. It has even invaded celestial mechanics, since chaos was found in the solar system. The book provides a unifying approach to these topics. The first part treats order and chaos in general. The other two parts deal with order and chaos in galaxies and with other applications in dynamical astronomy, ranging from celestial mechanics to general relativity and cosmology.
