  1. A Bacterium That Can Grow by Using Arsenic Instead of Phosphorus, Science Next Article Bookmark and Share

    Abstract: Life is mostly composed of the elements carbon, hydrogen, nitrogen, oxygen, sulfur, and phosphorus. Although these six elements make up nucleic acids, proteins, and lipids and thus the bulk of living matter, it is theoretically possible that some other elements in the periodic table could serve the same functions. Here, we describe a bacterium, strain GFAJ-1 of the Halomonadaceae, isolated from Mono Lake, California, which substitutes arsenic for phosphorus to sustain its growth. Our data show evidence for arsenate in macromolecules that normally contain phosphate, most notably nucleic acids and proteins. Exchange of one of the major bioelements may have profound evolutionary and geochemical significance.

  2. From the Connectome to the Synaptome: An Epic Love Story, Science Next Article Bookmark and Share

    Abstract: A major challenge in neuroscience is to decipher the structural layout of the brain. The term “connectome” has recently been proposed to refer to the highly organized connection matrix of the human brain. However, defining how information flows through such a complex system represents so difficult a task that it seems unlikely it could be achieved in the near future or, for the most pessimistic, perhaps ever. Circuit diagrams of the nervous system can be considered at different levels, although they are surely impossible to complete at the synaptic level. Nevertheless, advances in our capacity to marry macro- and microscopic data may help establish a realistic statistical model that could describe connectivity at the ultrastructural level, the “synaptome,” giving us cause for optimism.

  3. Swarm Intelligence in Animal Groups: When Can a Collective Out-Perform an Expert?, PLoS ONE Next Article Bookmark and Share

    Excerpt: Using a set of simple models, we present theoretical conditions (involving group size, and diversity of individual information) under which groups should aggregate information, or follow an expert, when faced with a binary choice. We found that, in single-shot decisions, experts are almost always more accurate than the collective across a range of conditions. However, for repeated decisions - where individuals are able to consider the success of previous decision outcomes - the collective's aggregated information is almost always superior.

  4. Networks and the Epidemiology of Infectious Disease, arXiv Next Article Bookmark and Share

    Excerpt: The science of networks has revolutionised research into the dynamics of interacting elements. It could be argued that epidemiology in particular has embraced the potential of network theory more than any other discipline. Here we review the growing body of research concerning the spread of infectious diseases on networks, focusing on the interplay between network theory and epidemiology. The review is split into four main sections, which examine: the types of network relevant to epidemiology; the multitude of ways these networks can be characterised; the statistical methods that can be applied to infer the epidemiological parameters on a realised network; and finally simulation and analytical methods to determine epidemic dynamics on a given network.

    1. Infectious Disease Modeling of Social Contagion in Networks, PLoS Comput Biol Next Article Bookmark and Share

      Excerpt: Information, trends, behaviors and even health states may spread between contacts in a social network, similar to disease transmission. However, a major difference is that as well as being spread infectiously, it is possible to acquire this state spontaneously. For example, you can gain knowledge of a particular piece of information either by being told about it, or by discovering it yourself. In this paper we introduce a mathematical modeling framework that allows us to compare the dynamics of these social contagions to traditional infectious diseases. (...) As an example, we study the spread of obesity (...)

    2. Untangling the Interplay between Epidemic Spread and Transmission Network Dynamics, PLoS Comput Biol Next Article Bookmark and Share

      Excerpt: The way potentially infectious contacts are made strongly influences how fast and how widely epidemics spread in their host population. Therefore, it is important to assess changes in contact behavior throughout an epidemic; these may occur due to external factors, such as demographic change, or as a side effect of the epidemic itself, leading to an accumulation of individuals with risky behavior in the infected population. We have developed a mathematical framework that allows for the study of the mutual interdependencies between epidemic spread and changes in contact behavior. The method is used to study HIV epidemics in model populations.

    3. Network Analysis of Global Influenza Spread, PLoS Comput Biol Next Article Bookmark and Share

      Excerpt: As evidenced by several historic vaccine failures, the design and implementation of the influenza vaccine remains an imperfect science. (...) On a local scale, our technique can output the most likely origins of a virus circulating in a given location. On a global scale, we can pinpoint regions of the world that would maximally disrupt viral transmission with an increase in vaccine implementation. We demonstrate our method on seasonal H3N2 and H1N1 and foresee similar application to other seasonal viruses, including swine-origin H1N1, once more seasonal data is collected.

    4. Imitation dynamics of vaccination behaviour on social networks, Proc. R. Soc. B Next Article Bookmark and Share

      Excerpt: The problem of achieving widespread immunity to infectious diseases by voluntary vaccination is often presented as a public-goods dilemma, as an individual's vaccination contributes to herd immunity, protecting those who forgo vaccination. The temptation to free-ride brings the equilibrium vaccination level below the social optimum. Here, we present an evolutionary game-theoretic approach to this problem, exploring the roles of individual imitation behaviour and population structure in vaccination.

  5. William Ury: The walk from "no" to "yes", TED.com Next Article Bookmark and Share

    About this talk:
    William Ury, author of "Getting Past No," offers an elegant, simple (but not easy) way to create agreement in even the most difficult situations -- from family conflict to, perhaps, the Middle East.

  6. Cycling in the Complexity of Early Societies, Cliodynamics Next Article Bookmark and Share

    Abstract Excerpt: Warfare is commonly viewed as a driving force of the process of aggregation of initially independent villages into larger and more complex political units that started several thousand years ago and quickly lead to the appearance of chiefdoms, states, and empires. Here we build on extensions and generalizations of Carneiro’s (1970) argument to develop a spatially explicit agent-based model of the emergence of early complex societies via warfare. (...) A general prediction of our model is continuous stochastic cycling in which the growth of individual polities in size, wealth/power, and complexity is interrupted by their quick collapse. (...)

  7. Secret US Embassy Cables, WikiLeaks Next Article Bookmark and Share

    Excerpt: Wikileaks began on Sunday November 28th publishing 251,287 leaked United States embassy cables, the largest set of confidential documents ever to be released into the public domain. The documents will give people around the world an unprecedented insight into US Government foreign activities.
    The cables, which date from 1966 up until the end of February this year, contain confidential communications between 274 embassies in countries throughout the world and the State Department in Washington DC. 15,652 of the cables are classified Secret.

  8. Energy: Supergrid, Nature Next Article Bookmark and Share

    Excerpt: (...) ten northern European nations are expected to sign a memorandum of understanding spelling out how they'll build an undersea electricity 'supergrid'. The project is a major engineering and political challenge, comparable in scope, scale and ambition to the rush for oil and gas in the same waters 40 years ago. Thousands of kilometres of undersea cable would be laid, at a cost of at least €1 million (US$1.4 million) per kilometre. (...)

  9. New Clues About What Makes the Human Brain Special, Science Next Article Bookmark and Share

    Excerpt: (...) researchers who've examined preserved samples of cerebral cortex from humans and several species of ape say they've found some intriguing clues about what makes the human brain unique. They report that in a particular region of the prefrontal cortex, an area that contributes to abstract thinking and other sophisticated cognition, neurons have more space between them in the human brain than in the brains of apes. This extra space allows more room for connections between neurons (...)

  10. Hierarchy and information in feedforward networks, arXiv Next Article Bookmark and Share

    Abstract: In this paper we define a hierarchical index for feedforward structures taking, as the starting point, three fundamental concepts underlying hierarchy: order, predictability and pyramidal structure. Our definition applies to the so called causal graphs, i.e., connected, directed acyclic graphs in which the arrows depict a direct causal relation between two elements defining the nodes. The estimator of hierarchy is obtained by evaluating the complexity of causal paths against the uncertainty in recovering them from a given end point. This naturally leads us to a definition of mutual information which, properly normalized and weighted through the layered structure of the graph, results in suitable index of hierarchy with strong theoretical grounds.

  11. Evolution of games microbes play, arXiv Next Article Bookmark and Share

    Abstract: When microbes compete for limited resources, they often engage in chemical warfare using bacterial toxins. This competition can be understood in terms of evolutionary game theory (EGT). We study the predictions of EGT for the bacterial "suicide bomber" game with two and three strategies, to simulations of these competitions with finite population sizes, but also allowing for probabilistic rather than pure strategies, as well as Darwinian adaptation. We find that Darwinian evolution of probabilistic strategies stabilizes games of the rock-paper-scissors type that emerge for parameters describing realistic bacterial populations, and points to ways in which the evolutionary stable strategy can be selected by changing those parameters.

  12. Sixteen common misconceptions about the evolution of cooperation in humans, Evolution and Human Behavior Next Article Bookmark and Share

    Abstract: The occurrence of cooperation poses a problem for the biological and social sciences. However, many aspects of the biological and social science literatures on this subject have developed relatively independently, with a lack of interaction. This has led to a number of misunderstandings with regard to how natural selection operates and the conditions under which cooperation can be favoured. Our aim here is to provide an accessible overview of social evolution theory and the evolutionary work on cooperation, emphasising common misconceptions.

  13. Environments that Induce Synthetic Microbial Ecosystems, PLoS Comput Biol Next Article Bookmark and Share

    Excerpt: Microbial metabolism affects biogeochemical cycles and human health. In most natural environments, multiple microbial species interact with each other, forming complex ecosystems whose properties are poorly understood. In an effort to understand inter-microbial interactions, and to explore new metabolic engineering avenues, researchers have started building artificial microbial ecosystems, e.g. pairs of genetically engineered strains that require each other for survival. (...) Surprisingly, we find that it is always possible to identify conditions that induce mutualistic or commensal interactions between any two species. Hence, our method should help in mapping naturally occurring microbe-microbe interactions, and in engineering new ones through a novel, environment-driven branch of synthetic ecology.

    1. Evolution of Cooperative Cross-Feeding Could Be Less Challenging Than Originally Thought, PLoS ONE Next Article Bookmark and Share

      Excerpt: The act of cross-feeding whereby unrelated species exchange nutrients is a common feature of microbial interactions and could be considered a form of reciprocal altruism or reciprocal cooperation. Past theoretical work suggests that the evolution of cooperative cross-feeding in nature may be more challenging than for other types of cooperation. Here we re-evaluate a mathematical model used previously to study persistence of cross-feeding and conclude that the maintenance of cross-feeding interactions could be favoured for a larger parameter ranges than formerly observed.

  14. Exuberant innovation: The Human Genome Project, arXiv Next Article Bookmark and Share

    Excerpt: We present a detailed synthesis of the development of the Human Genome Project (HGP) from 1986 to 2003 in order to test the "social bubble" hypothesis that strong social interactions between enthusiastic supporters of the HGP weaved a network of reinforcing feedbacks that led to a widespread endorsement and extraordinary commitment by those involved in the project, beyond what would be rationalized by a standard cost-benefit analysis in the presence of extraordinary uncertainties and risks.

  15. Scaling and Universality in River Flow Dynamics, arXiv Next Article Bookmark and Share

    Abstract: We investigate flow dynamics in rivers characterized by basin areas and daily mean discharge spanning different orders of magnitude. We show that the fluctuations evaluated at time scales ranging from days to months can be opportunely rescaled to the same non-Gaussian probability density function. Such a scaling breaks up above a certain critical horizon, where a behavior typical of thermodynamic systems at the critical point emerges. We finally show that both the scaling behavior and the break up of the scaling are universal features of river flow dynamics.

  16. Traffic flow on realistic road networks with adaptive traffic lights, arXiv Next Article Bookmark and Share

    Excerpt: We present a model of traffic flow on generic urban road networks based on cellular automata. We apply this model to an existing road network in the Australian city of Melbourne, using empirical data as input. For comparison, we also apply this model to a square-grid network using hypothetical input data. On both networks we compare the effects of non-adative vs adaptive traffic lights, in which instantaneous traffic state information feeds back into the traffic signal schedule. We observe that not only do adaptive traffic lights result in better averages of network observables, they also lead to significantly smaller fluctuations in these observables.

    1. On the kinetic theory of vehicular traffic flow: Chapman-Enskog expansion versus Grad's moment method, arXiv Next Article Bookmark and Share

      Excerpts: Based on a Boltzmann-like traffic equation for aggressive drivers we construct in this paper a second-order continuum traffic model which is similar to the Navier-Stokes equations for viscous fluids (...) Numerical simulations show that our Navier-Stokes-like traffic model satisfies the anisotropy condition and produces numerical results which are consistent with our daily experiences in real traffic.

  17. Thermal soaring flight of birds and unmanned aerial vehicles, arXiv Next Article Bookmark and Share

    Excerpt: Thermal soaring saves much energy, but flying large distances in this form represents a great challenge for birds, people and Unmanned Aerial Vehicles (UAVs). The solution is to make use of so-called thermals, which are localized, warmer regions in the atmosphere moving upwards with a speed exceeding the descent rate of birds and planes. Saving energy by exploiting the environment more efficiently is an important possibility for autonomous UAVs as well. Successful control strategies have been developed recently for UAVs in simulations and in real applications. (...)

  18. Outbreak properties of epidemic models: The roles of temporal forcing and stochasticity on pathogen invasion dynamics, Journal of Theoretical Biology Next Article Bookmark and Share

    Excerpt: Despite temporally forced transmission driving many infectious diseases, analytical insight into its role when combined with stochastic disease processes and non-linear transmission has received little attention. During disease outbreaks, however, the absence of saturation effects early on in well-mixed populations mean that epidemic models may be linearised and we can calculate outbreak properties, including the effects of temporal forcing on fade-out, disease emergence and system dynamics, via analysis of the associated master equations.

      Summary:
      Antonio Damasio has spent the past thirty years studying and writing about how the brain operates, and in this book, he goes against the long-standing idea that consciousness is somehow separate from the body, presenting compelling new scientific evidence that consciousness to begin with a biological process created by a living organism. (...) He also advances a radical hypothesis regarding the origins and varieties of feelings, which is central to his framework for the biological construction of consciousness: feelings are grounded in a near fusion of body and brain networks.

    2. Collective Animal Behavior, Princeton University Press Next Article Bookmark and Share

      Summary:
      Fish travel in schools, birds migrate in flocks, honeybees swarm, and ants build trails. How and why do these collective behaviors occur? Exploring how coordinated group patterns emerge from individual interactions, this book reveals why animals produce group behaviors and examines their evolution across a range of species. (...) Providing a synthesis of mathematics and biology, Sumpter constructs a unified appreciation of how different group-living species coordinate their behaviors and why natural selection has produced these groups. (...) Sumpter also shows how ideas about animal behavior can be applied to understanding human social behavior.

      Summary:
      This book examines hives, mounds, colonies, and swarms, whose complex systems of engagement and collective decision making have catalyzed innovations in engineering and can suggest solutions to such problems as climate change. The sophisticated system of decentralized interdependence exhibited by termites invites a lesson on how to respond to emergencies, while the chemical-based communications among African ants helped officials at Southwest Airlines define their seating policy. Insects, birds, and fish variously demonstrate the plausibility and success of disorganization leading to self-organization and leaderless processes. (...)

    4. Quantitative Sociodynamics: Stochastic Methods and Models of Social Interaction Processes, Springer Next Article Bookmark and Share

      Summary:
      This book presents a general strategy for interdisciplinary model building and its application to a quantitative description of behavioral changes based on social interaction processes. Originally, the crucial methods for the modeling of complex systems were developed in physics and mathematics, but they have very often proven their explanatory power in chemistry, biology, economics and the social sciences as well. Quantitative Sociodynamics provides a unified overview of the different stochastic methods, their interrelations and properties. In addition, it introduces important concepts from nonlinear dynamics (e.g. synergetics, chaos theory). The applicability of these fascinating concepts to social phenomena is carefully discussed.
