  1. Impossible reactions: Five chemistry rules broken, New Scientist Next Article Bookmark and Share

    Summary: Chemistry is a messy business. The elements are so diverse that their interactions can be unpredictable and sometimes bizarre. Often, chemists rely on nothing more than intuition to tell them what may or may not be possible.
    Sometimes that leads them astray. History is littered with ideas that were derided or dismissed at first, but eventually changed the rules of the game. Philip Ball tells five stories of chemistry they said could never happen

  2. Experimental evolution of multicellularity, PNAS Next Article Bookmark and Share

    Excerpt: Multicellularity was one of the most significant innovations in the history of life, but its initial evolution remains poorly understood. Using experimental evolution, we show that key steps in this transition could have occurred quickly. We subjected the unicellular yeast Saccharomyces cerevisiae to an environment in which we expected multicellularity to be adaptive. We observed the rapid evolution of clustering genotypes that display a novel multicellular life history characterized by reproduction via multicellular propagules, a juvenile phase, and determinate growth. (…)

  3. Public health: The toxic truth about sugar, Nature Next Article Bookmark and Share

    Summary:
    • Sugar consumption is linked to a rise in non-communicable disease
    • Sugar's effects on the body can be similar to those of alcohol
    • Regulation could include tax, limiting sales during school hours and placing age limits on purchase

  4. Education of a model student, PNAS Next Article Bookmark and Share

    Abstract: A dilemma faced by teachers, and increasingly by designers of educational software, is the trade-off between teaching new ma- terial and reviewing what has already been taught. Complicating matters, review is useful only if it is neither too soon nor too late. Moreover, different students need to review at different rates. We present a mathematical model that captures these issues in idea- lized form. The student’s needs are modeled as constraints on the schedule according to which educational material and review are spaced over time. Our results include algorithms to construct schedules that adhere to various spacing constraints, and bounds on the rate at which new material can be introduced under these schedules.

  5. Ariel Garten: Know thyself, with a brain scanner, TED.com Next Article Bookmark and Share

    About this talk: Imagine playing a video game controlled by your mind. Now imagine that game also teaches you about your own patterns of stress, relaxation and focus. At TEDxToronto Ariel Garten shows how looking at our own brain activity gives new meaning to the ancient dictum "know thyself."

    1. Lisa Harouni: A primer on 3D printing, TED.com Next Article Bookmark and Share

      About this talk: 2012 may be the year of 3D printing, when this three-decade-old technology finally becomes accessible and even commonplace. Lisa Harouni gives a useful introduction to this fascinating way of making things -- including intricate objects once impossible to create.

  6. Social networks and cooperation in hunter-gatherers, Nature Next Article Bookmark and Share

    Excerpt: Social networks show striking structural regularities, and both theory and evidence suggest that networks may have facilitated the development of large-scale cooperation in humans. Here, we characterize the social networks of the Hadza, a population of hunter-gatherers in Tanzania. We show that Hadza networks have important properties also seen in modernized social networks, including a skewed degree distribution, degree assortativity, transitivity, reciprocity, geographic decay and homophily. We demonstrate that Hadza camps exhibit high between-group and low within-group variation in public goods game donations. (…)

    1. Sex differences in intimate relationships, arXiv Next Article Bookmark and Share

      Excerpt: (…) social networks are themselves based on dyadic relationships and we have little understanding of the dynamics of close relationships and how these change over time. Evolutionary theory suggests that, even in monogamous mating systems, the pattern of investment in close relationships should vary across the lifespan (…) Mobile phone data sets provide us with a unique window into the structure of relationships and the way these change across the lifespan. We here use data from a large national mobile phone dataset to demonstrate striking sex differences in the pattern in the gender-bias (…) These results suggest that human social strategies may have more complex dynamics than we have tended to assume and a life-history perspective may be crucial for understanding them.

  7. Collective motion, arXiv Next Article Bookmark and Share

    Excerpt: We review the observations and the basic laws describing the essential aspects of collective motion -- being one of the most common and spectacular manifestations of coordinated behavior. (…) it is demonstrated, that in spite of considerable differences, a number of deep analogies exist between equilibrium statistical physics systems and those made of self-propelled (in most cases living) units. In both cases only a few well defined macroscopic/collective states occur and the transitions between these states follow a similar scenario, involving discontinuity and algebraic divergences.

    1. Multi-scale Inference of Interaction Rules in Animal Groups Using Bayesian Model Selection, PLoS Comput Biol Next Article Bookmark and Share

      Excerpt: The collective movement of animals in a group is an impressive phenomenon whereby large scale spatio-temporal patterns emerge from simple interactions between individuals. Theoretically, much of our understanding of animal group motion comes from models inspired by statistical physics. In these models, animals are treated as moving (self-propelled) particles that interact with each other according to simple rules. Recently, researchers have shown greater interest in using experimental data to verify which rules are actually implemented by a particular animal species. In our study, we present a rigorous selection between alternative models inspired by the literature for a system of glass prawns. We find that the classic theoretical models can accurately capture either the fine-scale behaviour or the large-scale collective patterns of movement of the prawns. However, none are able to reproduce both levels of description at the same time. (…)

    2. Consensus in networks of mobile communicating agents, arXiv Next Article Bookmark and Share

      Excerpt: Populations of mobile and communicating agents describe a vast array of technological and natural systems, ranging from sensor networks to animal groups. Here, we investigate how a group-level agreement may emerge in the continuously evolving network defined by the local interactions of the moving individuals. We adopt a general scheme of motion in two dimensions and we let the individuals interact through the minimal naming game, a prototypical scheme to investigate social consensus.

  8. From Social Networks to Collaboration Networks: The Next Evolution of Social Media for Business, Forbes Next Article Bookmark and Share

    Excerpt: But the biggest value that social networks offer goes beyond being marketing channels to push communication to prospects and customers. They are morphing into new channels for collaboration and innovation. Social networks are becoming unique touch points to engage communities, start conversations, recruit skillful employees, and develop new innovative ideas. Firms that successfully leverage social networks are doing so to engage their communities in conversation explicitly to tap into their brainpower and energy. They ask customers and followers to participate in brainstorming with them so they can learn how to be a better company, offer better products and services, or support the values and issues of the community.

      Summary: How do we make corporations more like cities, which get more productive as they grow bigger? Help me with my ongoing research project.

  9. Evolving cooperation, Journal of Theoretical Biology Next Article Bookmark and Share

    Excerpt: This article is a brief introduction to the special issue "Evolution of cooperation" published by the Journal of Theoretical Biology to mark its 50th anniversary. [...] I give a short overview of the papers in this issue and provide an outlook of some of the goals that might lie ahead.

  10. Mixed Messages on Prices and Food Security, Science Next Article Bookmark and Share

    Excerpt: Spikes in food prices have pushed food security to the top of the global policy agenda. Price increases have mixed effects on poverty and hunger: They increase the cost of food for consumers but increase incomes of farmers, who represent the bulk of the world's poor. Net effects will differ depending on whether poor households or countries buy or import, or sell or export food (infrastructure, institutions, and market imperfections will play roles, as well). Policies to influence prices imply winners and losers, not just between rich and poor, but also among the poor. These nuances are too often absent in public debate, to the detriment of policy-making. Moreover, the arguments put forward today, that high food prices generally hurt the poor, are in contrast with those put forward a few years ago, that low food prices were hurting the poor.

  11. Knowledgeable individuals lead collective decisions in ants, J Exp Biol Next Article Bookmark and Share

    Excerpt: Self-organisation underlies many collective processes in large animal groups, where coordinated patterns and activities emerge at the group level from local interactions among its members. Although the importance of key individuals acting as effective leaders has recently been recognised in certain collective processes, it is widely believed that self-organised decisions are evenly shared among all or a subset of individuals acting as decision-makers, unless there are significant conflicts of interests among group members. Here, we show that certain individuals are disproportionately influential in self-organised decisions in a system where all individuals share the same interests: nest site selection by the ant Temnothorax albipennis.

  12. A review of evolutionary graph theory with applications to game theory, Biosystems Next Article Bookmark and Share

    Excerpt: Evolutionary graph theory (EGT), studies the ability of a mutant gene to overtake a finite structured population. In this review, we describe the original framework for EGT and the major work that has followed it.

  13. Noise-induced volatility of collective dynamics, Phys. Rev. E Next Article Bookmark and Share

    Abstract: Noise-induced volatility refers to a phenomenon of increased level of fluctuations in the collective dynamics of bistable units in the presence of a rapidly varying external signal, and intermediate noise levels. The archetypical signature of this phenomenon is that"beyond the increase in the level of fluctuations"the response of the system becomes uncorrelated with the external driving force, making it different from stochastic resonance. Numerical simulations and an analytical theory of a stochastic dynamical version of the Ising model on regular and random networks demonstrate the ubiquity and robustness of this phenomenon, which is argued to be a possible cause of excess volatility in financial markets, of enhanced effective temperatures in a variety of out-of-equilibrium systems, and of strong selective responses of immune systems of complex biological organisms. Extensive numerical simulations are compared with a mean-field theory for different network topologies.

  14. Traffic Jam Economics, NYTimes Next Article Bookmark and Share

    Excerpt: Sometimes, trying to get someplace faster, we end up slowing one another down. Traffic jams try our patience, waste our time and worsen the quality of our air.
    Urban congestion exemplifies the larger problem of effectively coordinating individual decisions to use largely unpriced goods like roads. Drivers are adept at anticipating delays and factoring them into decisions on whether and when to hit the road. But, absent tolls, they are not compelled to factor in the delays their driving imposes on others.

  15. The Role of Coevolution, Science Next Article Bookmark and Share

    Summary: One of the great metaphors of evolutionary biology, introduced by Sewall Wright, is that populations evolve toward adaptive peaks separated by adaptive valleys. The peaks are combinations of genes that confer high Darwinian fitness on individuals, whereas the valleys are combinations that confer low fitness. But how can a population move from one peak to another, perhaps higher, peak, across an adaptive valley in which gene combinations are presumed to be maladaptive? (…) Meyer et al. show that coevolution may favor key innovations that guide a population quickly onto the slope of a different adaptive peak.

  16. Conditional strategies and the evolution of cooperation in spatial public goods games, arXiv Next Article Bookmark and Share

    Excerpt: The fact that individuals will most likely behave differently in different situations begets the introduction of conditional strategies. Inspired by this, we study the evolution of cooperation in the spatial public goods game, where besides unconditional cooperators and defectors, also different types of conditional cooperators compete for space. Conditional cooperators will contribute to the public good only if other players within the group are likely to cooperate as well, but will withhold their contribution otherwise. Depending on the number of other cooperators that are required to elicit cooperation of a conditional cooperator, the latter can be classified in as many types as there are players within each group. We find that the most cautious cooperators, such that require all other players within a group to be conditional cooperators, are the undisputed victors of the evolutionary process, even at very low synergy factors.

  17. The Roman Dominate from the Perspective of Demographic-Structural Theory, Cliodynamics Next Article Bookmark and Share

    Abstract: The Dominate Cycle is an application of demographic-structural theory in a historical work. It seeks to interpret demographic and economic trends seen in a wide variety of primary sources from Late Antiquity in the context of secular cycles. It attempts to shed light on why the Roman Empire declined and fell in the West and survived in the East, to help resolve one of the longest standing debates in modern historiography.

    1. War Games: Simulating Collins’ Theory of Battle Victory, Cliodynamics Next Article Bookmark and Share

      Abstract: Collins’ recent theory on battle dynamics is converted into a system of interconnected equations and simulated. Between evenly matched armies, initial advantages are shown to be difficult to overcome due to the numerous reinforcing pathways throughout the model. Morale advantages are shown to lead to quick victories, while material advantages lead to longer wars often won through attrition. A simulation of the Civil War is provided that appears to coincide with historical reality. The implications of these simulations for Collins’ broader theory are briefly discussed.

    2. A Trap At The Escape From The Trap? Demographic-Structural Factors of Political Instability in Modern Africa and West Asia, Cliodynamics Next Article Bookmark and Share

      Abstract: The escape from the “Malthusian trap” is shown to tend to generate in a rather systematic way quite serious political upheavals. Some demographic structural mechanisms that generate such upheavals have been analyzed, which has made it possible to develop a mathematical model of the respective processes. The forecast of political instability in African and West Asian countries in 2012"2050 produced on the basis of this model is presented.

  18. 8 Wild Proposals to Relocate Endangered Species, Wired Next Article Bookmark and Share

    Excerpt: It's called assisted migration. Often the goal is to save endangered plants and animals, though not always. Sometimes, as with the Komodo dragon proposal, the goal is to restore ecological balance, and other proposals are motivated by an almost romantic sense of possibility: Wouldn't it be marvelous to watch cheetahs dash across the grasslands of South Dakota?

    1. Design in Nature: How the Constructal Law Governs Evolution in Biology, Physics, Technology, and Social Organization, Doubleday Next Article Bookmark and Share

      Summary:
      In this groundbreaking book, Adrian Bejan takes the recurring patterns in nature-trees, tributaries, air passages, neural networks, and lightning bolts-and reveals how a single principle of physics, the Constructal Law, accounts for the evolution of these and all other designs in our world. Everything-from biological life to inanimate systems-generates shape and structure and evolves in a sequence of ever-improving designs in order to facilitate flow. River basins, cardiovascular systems, and bolts of lightning are very efficient flow systems to move a current-of water, blood, or electricity. Likewise, the more complex architecture of animals evolve to cover greater distance per unit of useful energy, or increase their flow across the land. Such designs also appear in human organizations, like the hierarchical "flowcharts" or reporting structures in corporations and political bodies.

    2. I Is an Other: The Secret Life of Metaphor and How It Shapes the Way We See the World, Harper Perennial Next Article Bookmark and Share

      Summary:
      From President Obama's political rhetoric to the bursting of the housing bubble, from conversations to commercials, James Geary shows that every aspect of our day-to-day experience is molded by metaphor. Geary takes readers from Aristotle's investigation of metaphor right up to the latest neuroscientific insights into how metaphor works in the brain. Witty, persuasive, and original, I Is an Other explores metaphor's effects on financial decision making, effective advertising, leadership, learning, and more. Romeo's exclamation "It is the East, and Juliet is the sun!" may be one of the most well-known metaphors in literature, but metaphor is more than a device of love-struck poets. As Geary demonstrates, metaphor has leaped off the page and landed with a mighty splash right in the middle of the stream of consciousness.

    3. The Evolved Apprentice: How Evolution Made Humans Unique, A Bradford Book Next Article Bookmark and Share

      Summary:
      Over the last three million years or so, our lineage has diverged sharply from those of our great ape relatives. Change has been rapid (in evolutionary terms) and pervasive. Morphology, life history, social life, sexual behavior, and foraging patterns have all shifted sharply away from other great apes. No other great ape lineage--including those of chimpanzees and gorillas--seems to have undergone such a profound transformation. In this book, Sterelny argues that the divergence stems from the fact that humans gradually came to enrich the learning environment of the next generation. Humans came to cooperate in sharing information, and to cooperate ecologically and reproductively as well, and these changes initiated positive feedback loops that drove us further from other great apes. Sterelny develops a new theory of the evolution of human cognition and human social life that emphasizes the gradual evolution of information sharing practices across generations and how information sharing transformed human minds and social lives. Sterelny proposes that humans developed a new form of ecological interaction with their environment, cooperative foraging, which led to positive feedback linking ecological cooperation, cultural learning, and environmental change. The ability to cope with the immense variety of human ancestral environments and social forms, he argues, depended not just on adapted minds but also on adapted developmental environments.

    4. The New Quantum Age: From Bell's Theorem to Quantum Computation and Teleportation, Oxford University Press Next Article Bookmark and Share

      Summary:
      While quantum theory has been used to study the physical universe with great profit, both intellectual and financial, ever since its discovery eighty-five years ago, over the last fifty years we have found out more and more about the theory itself, and what it tells us about the universe. It seems we may have to accept non-locality (cause and effect may be light-years apart), loss of realism (nature may be fundamentally probabilistic) and non-determinism (it seems that God does play dice). This book, totally up-to-date and written by an expert in the field, explains the emergence of our new perspective on quantum theory, but also describes how the ideas involved in this re-evaluation led seamlessly to a totally new discipline - quantum information theory. This discipline includes quantum computation, which is able to perform tasks quite out of the range of other computers; the totally secure algorithms of quantum cryptography; and quantum teleportation - as part of science fact rather than science fiction.
