  1. Ageing, Nature Next Article Bookmark and Share

    Excerpt: It is now clear that by tinkering with particular signalling pathways and by balancing nutrition, the lifespan of many organisms, including yeast, worms, flies and mice, can be extended. Crucially, the same tweaks often bring about substantial health benefits and seem to delay the onset of age-related diseases. Most of the pathways involved are evolutionarily conserved, so it is likely that some of this research will eventually benefit human health.

  2. What's Old Is New: 1918 Virus Matches 2009 H1N1 Strain, Science Next Article Bookmark and Share

    Excerpt: The "novel" H1N1 swine influenza virus that last year caused the first human pandemic in 4 decades has one feature that is hardly novel: Its surface protein, hemagglutinin (HA)â€"which spikes cells and starts an infectionâ€"closely matches the HA in the H1N1 virus responsible for the 1918 pandemic. Separated by 91 years, the two strains of the highly mutable virus ought to be vastly different. This newfound similarity answers many mysteries about the 2009 pandemic, including why it largely spared the elderly.

  3. Measuring Autonomy and Emergence via Granger Causality, Artificial Life Next Article Bookmark and Share

    Excerpt: Concepts of emergence and autonomy are central to artificial life and related cognitive and behavioral sciences. However, quantitative and easy-to-apply measures of these phenomena are mostly lacking. Here, I describe quantitative and practicable measures for both autonomy and emergence, based on the framework of multivariate autoregression and specifically Granger causality. G-autonomy measures the extent to which the knowing the past of a variable helps predict its future, as compared to predictions based on past states of external (environmental) variables. G-emergence measures the extent to which a process is both dependent upon and autonomous from its underlying causal factors

    1. Quantifying Emergence in term of Persistent Mutual Information, arXiv Next Article Bookmark and Share

      Excerpt: We define Persistent Mutual Information (PMI) as the Mutual (Shannon)Information between the past history of a system and its evolution significantly later in the future. This quantifies how much past observations enable long term prediction, which we propose as the primary signature of (Strong) Emergent Behaviour.

  4. Looking Beyond Silicon, Science Next Article Bookmark and Share

    Excerpt: Silicon-based electronics have been the mainstay of the industry for several decades, a veritable powerhouse of the economy, driving technological breakthroughs that affect virtually all aspects of everyday life. Devices have gotten smaller, faster, more efficient, more powerful, and cheaper. However, the size of transistorsâ€"the building blocks of electronicsâ€"is approaching the limits of what can be done on a large-scale industrial basis. Has the time come when a replacement for silicon can no longer be avoided? If we look beyond raw processing power, might there be a future for silicon if it is given new capabilities?

    1. An Emergent Change of Phase for Electronics, Science Next Article Bookmark and Share

      Abstract: Correlated electrons in transition metal oxides can form a variety of electronic phases. The phase change between these various states gives rise to novel device functions, including sensing, signal conversion, and nonvolatile memory, and is now at the frontier of research on "emergent research device materials." Those oxide devices may have an advantage over conventional semiconductor devices for added functionality and future downsizing to the nanoscale. The elucidation of the microscopic physics behind their operation is a key step for further development.

  5. Wireless Technology: The Birds and the Bees ... and 4G, Knowledge@Wharton Next Article Bookmark and Share

    Summary:
    Just when consumers thought they had their 3G wireless gadgets all figured out, it's now time to start getting a grip on the fourth generation of wireless technology -- which will be much faster and far more disruptive than anything we have experienced before, according to Scott Snyder in his recent Wharton School Publishing book titled, The New World of Wireless: How to Compete in the 4G Revolution. In an interview with Knowledge@Wharton, Snyder, who is president and COO of consulting firm Decision Strategies International, predicts 4G will revolutionize the way we work and play by creating "one giant wireless ecosystem" that buzzes with innovation.

  6. Information dynamics shape the sexual networks of Internet-mediated prostitution, PNAS Next Article Bookmark and Share

    Excerpt: Like many other social phenomena, prostitution is increasingly coordinated over the Internet. The online behavior affects the offline activity; the reverse is also true. We investigated the reported sexual contacts between 6,624 anonymous escorts and 10,106 sex buyers extracted from an online community from its beginning and six years on. These sexual encounters were also graded and categorized (in terms of the type of sexual activities performed) by the buyers. From the temporal, bipartite network of posts, we found a full feedback loop in which high grades on previous posts affect the future commercial success of the sex worker, and vice versa.

  7. Spontaneous Synchrony Breaking, arXiv Next Article Bookmark and Share

    Abstract: Research on synchronization of coupled oscillators has helped explain how uniform behavior emerges in populations of non-uniform systems. But explaining how uniform populations engage in sustainable non-uniform synchronization may prove to be just as fascinating.

  8. Codd's Self-Replicating Computer, Artificial Life Next Article Bookmark and Share

    Excerpt: Edgar Codd's 1968 design for a self-replicating cellular automaton has never been implemented. Partly this is due to its enormous size, but we have also identified four problems with the original specification that would prevent it from working. These problems potentially cast doubt on Codd's central assertion, that the eight-state space he presents supports the existence of machines that can act as universal constructors and computers. However, all these problems were found to be correctable, and we present a complete and functioning implementation after making minor changes to the design and transition table.

    1. Using Economy of Means to Evolve Transition Rules within 2D Cellular Automata, Artificial Life Next Article Bookmark and Share

      Excerpt: Running a cellular automaton (CA) on a rectangular lattice is a time-honored method for studying artificial life on a digital computer. Commonly, the researcher wishes to investigate some specific or general mode of behavior, say, the ability of a coherent pattern of points to glide within the lattice, or to generate copies of itself. This technique has a problem: how to design the transitions tableâ€"the set of distinct rules that specify the next content of a cell from its current content and that of its near neighbors. Often the table is painstakingly designed manually, rule by rule. The problem is exacerbated by the potentially vast number of individual rules that need be specified to cover all combinations of center and neighbors when there are several symbols in the alphabet of the CA. In this article a method is presented to have the set of rules evolve automatically while running the CA. The transition table is initially empty, with rules being added as the need arises. A novel principle drives the evolution: maximum economy of meansâ€"maximizing the reuse of rules introduced on previous cycles.

  9. Science-Based Health Care, Science Next Article Bookmark and Share

    Excerpt: The provision of adequate health care is one of the major challenges for modern societies. It is an especially tough task in developing countries with limited resources and insufficient capacity. Obstacles are even encountered at the conceptual level: For example, a traditional misconception is that spending on health is a social burden, instead of being a strategic investment essential for each nation's socioeconomic development. According to economic analyses, health system innovations will not only improve livelihoods but also boost internal consumption and job opportunities. But these innovations cannot succeed without the strong support of science.

  10. Patient Referral Patterns and the Spread of Hospital-Acquired Infections through National Health Care Networks, PLoS Comput Biol Next Article Bookmark and Share

    Summary: The prevalence of hospital acquired infections is widely believed to reflect the quality of health care in individual hospitals, and is therefore often used as a benchmark. Intuitively, the idea is that infections spread more easily in hospitals with a poor quality of health care. This assumes that the rate at which admitted patients introduce new infections is the same for all hospitals. In this article, we show that this assumption is unlikely to be correct. Using national data on patient admissions, we are able to reconstruct the entire hospital network consisting of patients referred between hospitals. This network reveals that university hospitals admit more patients that recently stayed in other hospitals. Consequently, they are more likely to admit patients that still carry pathogens acquired during their previous hospital stay. Therefore, the prevalence of infections does not only reflect the quality of health care but also the connectedness to hospitals from which patients are referred. This phenomenon is missed at the single hospital level; our study is the first to address the connectedness between hospitals in explaining the prevalence of hospital acquired infections. Our findings imply that interventions should focus on hospitals that are central in the network of patient referrals.

  11. Evolutionary establishment of moral and double moral standards through spatial interactions, arXiv Next Article Bookmark and Share

    Excerpt: Situations where individuals have to contribute to joint efforts or share scarce resources are ubiquitous. Yet, without proper mechanisms to ensure cooperation, the evolutionary pressure to maximize individual success tends to create a tragedy of the commons (such as over-fishing or the destruction of our environment). This contribution addresses a number of related puzzles of human behavior with an evolutionary game theoretical approach as it has been successfully used to explain the behavior of other biological species many times, from bacteria to vertebrates. Our agent-based model distinguishes individuals applying four different behavioral strategies: non-cooperative individuals ("defectors"), cooperative individuals abstaining from punishment efforts (called "cooperators" or "second-order free-riders"), cooperators who punish non-cooperative behavior ("moralists"), and defectors, who punish other defectors despite being non-cooperative themselves ("immoralists"). (...)

    1. Emergence of Spatial Structure in Cell Groups and the Evolution of Cooperation, PLoS Comput Biol Next Article Bookmark and Share

      Summary: Cooperation is a fundamental and widespread phenomenon in nature, yet explaining the evolution of cooperation is difficult. Natural selection typically favors individuals that maximize their own reproduction, so how is it that many diverse organisms, from bacteria to humans, have evolved to help others at a cost to themselves? Research has shown that cooperation can most readily evolve when cooperative individuals preferentially help each other, but this leaves open another critical question: How do cooperators achieve selective interaction with one another? We focus on this question in the context of unicellular organisms, such as bacteria, which exhibit simple forms of cooperation that play roles in nutrient acquisition and pathogenesis. We use a realistic simulation framework to model large cell groups, and observe that cell lines can spontaneously segregate from each other in space as the group expands. Finally, we demonstrate that lineage segregation allows cooperative cell types to preferentially benefit each other, thereby favoring the evolution of cooperation.

    2. Markets, Religion, Community Size, and the Evolution of Fairness and Punishment, Science Next Article Bookmark and Share

      Excerpt: Large-scale societies in which strangers regularly engage in mutually beneficial transactions are puzzling. The evolutionary mechanisms associated with kinship and reciprocity, which underpin much of primate sociality, do not readily extend to large unrelated groups. Theory suggests that the evolution of such societies may have required norms and institutions that sustain fairness in ephemeral exchanges. If that is true, then engagement in larger-scale institutions, such as markets and world religions, should be associated with greater fairness, and larger communities should punish unfairness more. Using three behavioral experiments administered across 15 diverse populations, we show that market integration (measured as the percentage of purchased calories) positively covaries with fairness while community size positively covaries with punishment.

  12. Characteristics of Pattern Formation and Evolution in Approximations of Physarum Transport Networks, Artificial Life Next Article Bookmark and Share

    Excerpt: Most studies of pattern formation place particular emphasis on its role in the development of complex multicellular body plans. In simpler organisms, however, pattern formation is intrinsic to growth and behavior. Inspired by one such organism, the true slime mold Physarum polycephalum, we present examples of complex emergent pattern formation and evolution formed by a population of simple particle-like agents. Using simple local behaviors based on chemotaxis, the mobile agent population spontaneously forms complex and dynamic transport networks. By adjusting simple model parameters, maps of characteristic patterning are obtained.

    1. Biomimetic Control Based on a Model of Chemotaxis in Escherichia coli, Artificial Life Next Article Bookmark and Share

      Excerpt: (...) Here we selected the bacterium Escherichia coli as a target organism (...) We particularly focused on a motility response known as chemotaxis and developed a computer model that includes not only intracellular information processing but also motor control. After confirming the effectiveness and validity of the proposed model by a series of computer simulations, we applied it to a mobile robot control problem. This is probably the first study showing that a bacterial model can be used as an autonomous control algorithm. Our results suggest that many excellent models proposed thus far for biochemical purposes can be applied to problems in other fields.

  13. Epidemic prevalence on random mobile dynamical networks: individual heterogeneity and correlation, Eur. Phys. J. B Next Article Bookmark and Share

    Abstract: In this paper, we extend the susceptible-infected-susceptible (SIS) epidemiological model on a random dynamical network composed of mobile individuals, in which the infection is caused by the collisions between susceptible and infected individuals at the spreading rate proportional to their susceptibilities and infectivities. We analytically study the criticality of spreading dynamics under different distributions of individual susceptibility and infectivity, and numerically verify the cases of power-law and (or) Gaussian distributions. Our findings show that the heterogeneity of individual susceptibility and infectivity increases the epidemic threshold, and the positive correlation of individual susceptibility and infectivity avails to the epidemic prevalence.

  14. Specialization Can Drive the Evolution of Modularity, PLoS Comput Biol Next Article Bookmark and Share

    Summary: Throughout life's history, organisms have produced evolutionary innovations, features that are useful when facing new ecological and environmental challenges. A property that aids in the production of such innovations is modularity. Modular systems consist of groups of molecules with many interactions within a group but fewer interactions between groups. Such modularity increases the chances of innovation, because it allows changes inside one module without perturbing others, and because it permits redeployment of modules to create new biological functions. We simulate the evolution of gene networks known to be important in development to show that modularity increases when selection favors specialization in gene activity. Specialization occurs wherever new cell types, organs, or other body structures arise. In the course of this process gene networks acquire the ability to produce new gene activity patterns specific to these structures. We also demonstrate how modularity favors the evolution of new gene activity patterns that make use of already existing modules. Because specialization in gene activity is very common in evolution, the mechanism that we put forward may be important for the origins of modularity in gene regulatory networks.

  15. Scaling Behaviors of Weighted Food Webs as Energy Transportation Networks, arXiv Next Article Bookmark and Share

    Excerpt: Food webs can be regarded as energy transporting networks in which the weight of each edge denotes the energy flux between two species. By investigating 21 empirical weighted food webs as energy flow networks, we found several ubiquitous scaling behaviors.

  16. The Young, the Weak and the Sick: Evidence of Natural Selection by Predation, PLoS ONE Next Article Bookmark and Share

    Excerpt: It is assumed that predators mainly prey on substandard individuals, but even though some studies partially support this idea, evidence with large sample sizes, exhaustive analysis of prey and robust analysis is lacking. [...] This article provides a reliable example of how natural selection may operate in the wild and proves that predators mainly prey on substandard individuals.

  17. The Suppression of Immune System Disorders by Passive Attrition, PLoS ONE Next Article Bookmark and Share

    Excerpt: Exposure to infectious diseases has an unexpected benefit of inhibiting autoimmune diseases and allergies. This is one of many fundamental fitness tradeoffs associated with immune system architecture. The immune system attacks pathogens, but also may (inappropriately) attack the host.[...] This study focuses on physiological constraints that lead to competition for survival between immune system cell types.

  18. 'Tarzan Economics': If Music Is Free, How Do Artists Get Paid?, Knowledge@Wharton Next Article Bookmark and Share

    Summary: Over the past decade, the music industry was roundly criticized for how it responded to the proliferation of digital content -- launching hundreds of lawsuits against otherwise law-abiding consumers who downloaded music. Although many companies have backed off from that approach, the challenge remains to find a business model for digital music. If songs can be downloaded and traded for free, how do the musicians, recording engineers and record company executives get paid?

    1. Complex Time-Delay Systems: Theory and Applications (Understanding Complex Systems), Springer Next Article Bookmark and Share

      Summary:
      Time delays in dynamical systems arise as an inevitable consequence of finite speeds of information transmission. Realistic models increasingly demand the inclusion of delays in order to properly understand, analyze, design, and control real-life systems. The goal of this book is to present the state-of-the-art in research on time-delay dynamics in the framework of complex systems and networks. While the mathematical theory of delay equations is quite mature, its application to the particular problems of complex systems and complexity is a newly emerging field, and the present volume aims to play a pioneering role in this perspective.

      Summary:
      With respect to the possible outlining of new models of the process of knowledge construction, we are really faced, at the moment, with the appearance of a new frontier: a frontier that appears strictly linked to the emergence of a conceptual revolution at the level of the analysis of that peculiar entanglement of complexity, information, causality, meaning, emergence, teleology and intentionality that characterizes the unfolding of the "natural forms" of human cognition. To recognize some of the peculiar knots of this particular conceptual revolution precisely constitutes the first target of the volume. (...)
