  1. Complex systems: Unzipping Zipf's law, Nature Next Article Bookmark and Share

    Excerpt: Perhaps the only thing more abundant in both natural and man-made systems than power laws are the models that have been developed to explain them. Writing in the New Journal of Physics, Baek et al. argue that because such models depend on the specifics of each system, they fail to capture the shared cause of this regularity. The authors instead propose a general model that can be applied to any division of items into groups, and that can, for example, account for Zipf's law of word frequencies in text, the popularity of last names, and city and county populations.

  2. Next Step: DNA Robots?, Science Next Article Bookmark and Share

    Excerpt: DNA nanotechnology isn't only about using DNA as a set of tiny Tinkertoys. Researchers in the field have long sought to use DNA's ability to store and manipulate information to build a DNA computer. But after years of tryingâ€"and failingâ€"to outdo conventional computer technology, the field is finally advancing by going back to DNA's biochemical roots.

  3. In Evolution, the Sum Is Less than Its Parts, Science Next Article Bookmark and Share

    Excerpt: Propagating bacteria in a lab for thousands of generations may seem tedious, or even irrelevant, to most evolutionary biologists. Nonetheless, such experiments provide an opportunity to deduce quantitative principles of evolution and directly test them in controlled environments. Combined with modern sequencing technologies, as well as theory, recent microbial experiments have suggested a critical role for genetic interactions among mutations, called epistasis, in determining the pace of evolution. (...)

  4. Cryptic genetic variation promotes rapid evolutionary adaptation in an RNA enzyme, Nature Next Article Bookmark and Share

    Excerpt: Cryptic variation is caused by the robustness of phenotypes to mutations. Cryptic variation has no effect on phenotypes in a given genetic or environmental background, but it can have effects after mutations or environmental change. Because evolutionary adaptation by natural selection requires phenotypic variation, phenotypically revealed cryptic genetic variation may facilitate evolutionary adaptation. This is possible if the cryptic variation happens to be pre-adapted, or “exapted”, to a new environment, and is thus advantageous once revealed. (...) Here we show that populations of RNA enzymes with accumulated cryptic variation adapt more rapidly to a new substrate than a population without cryptic variation. (...) Our observations show that cryptic variation contains new genotypes pre-adapted to a changed environment. Our results highlight the positive role that robustness and epistasis can have in adaptive evolution.

  5. Carlo Ratti: Architecture that senses and responds, TED.com Next Article Bookmark and Share

    About this talk: With his team at SENSEable City Lab, MIT's Carlo Ratti makes cool things by sensing the data we create. He pulls from passive data sets -- like the calls we make, the garbage we throw away -- to create surprising visualizations of city life. And he and his team create dazzling interactive environments from moving water and flying light, powered by simple gestures caught through sensors.

    1. Aaron O'Connell: Making sense of a visible quantum object, TED.com Next Article Bookmark and Share

      About this talk: Physicists are used to the idea that subatomic particles behave according to the bizarre rules of quantum mechanics, completely different to human-scale objects. In a breakthrough experiment, Aaron O'Connell has blurred that distinction by creating an object that is visible to the unaided eye, but provably in two places at the same time. In this talk he suggests an intriguing way of thinking about the result.

    2. Damon Horowitz calls for a "moral operating system", TED.com Next Article Bookmark and Share

      About this talk: At TEDxSiliconValley, Damon Horowitz reviews the enormous new powers that technology gives us: to know more -- and more about each other -- than ever before. Drawing the audience into a philosophical discussion, Horowitz invites us to pay new attention to the basic philosophy -- the ethical principles -- behind the burst of invention remaking our world. Where's the moral operating system that allows us to make sense of it?

  6. A Quantitative Test of Hamilton's Rule for the Evolution of Altruism, PLoS Biol Next Article Bookmark and Share

    Excerpt: In this study, we conduct simulations with the help of a simulated system of foraging robots to manipulate the costs and benefits of altruism and determine the conditions under which altruism evolves. By conducting experimental evolution over hundreds of generations of selection in populations with different costs and benefits of altruistic behavior, we show that kin selection theory always accurately predicts the minimum relatedness necessary for altruism to evolve.

  7. Behavior and the Dynamic Genome, Science Next Article Bookmark and Share

    Excerpt: When circumstances change, an organism's first response is often behavioral. But how does adaptive behavior evolve, given that it requires constant and often instantaneous interactions between an individual and its environment? The dominant view emphasizes new random DNA mutation as the starting point. This may lead to behavioral variation. If the resulting variants have different fitness values, then natural selection could result in behavioral evolution through changes in allele frequencies across generations. An alternative theory proposes environmentally induced change in an organism's behavior as the starting point, and “phenotypic plasticity” that is inherited across generations through an unspecified process of “genetic assimilation”.

  8. Interactive Evolution of Camouflage, Artificial Life Next Article Bookmark and Share

    Excerpt: This article presents an abstract computation model of the evolution of camouflage in nature. The 2D model uses evolved textures for prey, a background texture representing the environment, and a visual predator. A human observer, acting as the predator, is shown a cohort of 10 evolved textures overlaid on the background texture. The observer clicks on the five most conspicuous prey to remove (“eat”) them. (...)

  9. Adaptation and Evolutionary Rescue in Metapopulations Experiencing Environmental Deterioration, Science Next Article Bookmark and Share

    Excerpt: It is not known whether evolution will usually be rapid enough to allow a species to adapt and persist in a deteriorating environment. We tracked the eco-evolutionary dynamics of metapopulations with a laboratory model system of yeast exposed to salt stress. (...) evolutionary dynamics affect both the persistence and the range of a species after environmental deterioration.

  10. Niche as a Determinant of Word Fate in Online Groups, PLoS ONE Next Article Bookmark and Share

    Excerpt: Patterns of word use both reflect and influence a myriad of human activities and interactions. Like other entities that are reproduced and evolve, words rise or decline depending upon a complex interplay between their intrinsic properties and the environments in which they function. Using Internet discussion communities as model systems, we define the concept of a word niche as the relationship between the word and the characteristic features of the environments in which it is used. (...)

  11. Untethered Hovering Flapping Flight of a 3D-Printed Mechanical Insect, Artificial Life Next Article Bookmark and Share

    Abstract: This project focuses on developing a flapping-wing hovering insect using 3D-printed wings and mechanical parts. The use of 3D printing technology has greatly expanded the possibilities for wing design, allowing wing shapes to replicate those of real insects or virtually any other shape. It has also reduced the time of a wing design cycle to a matter of minutes. An ornithopter with a mass of 3.89 g has been constructed using the 3D printing technique and has demonstrated an 85-s passively stable untethered hovering flight. This flight exhibits the functional utility of printed materials for flapping-wing experimentation and ornithopter construction and for understanding the mechanical principles underlying insect flight and control.

  12. The thermodynamic meaning of negative entropy, Nature Next Article Bookmark and Share

    Excerpt: Landauer’s principle states that the erasure of data stored in a system has an inherent work cost and therefore dissipates heat. However, this consideration assumes that the information about the system to be erased is classical, and does not extend to the general case where an observer may have quantum information about the system to be erased, for instance by means of a quantum memory entangled with the system. Here we show that the standard formulation and implications of Landauer’s principle are no longer valid in the presence of quantum information.

  13. Slime mould prefers sedatives, say researchers, BBC News Next Article Bookmark and Share

    Excerpt:
    The slime mould at centre sought out sleeping tablets (l) significantly more than honey (r)
    Physarum polycephalum is known to grow toward food sources, and this propensity has been exploited to solve mazes and even to mimic "logic gates", the building blocks of computers.
    It is normally fed honey or oats in these experiments, but a paper in Nature Precedings suggests that plants and commercial tablets with sedative effects work far better.

  14. Measuring the Evolution of the Drivers of Technological Innovation in the Patent Record, Artificial Life Next Article Bookmark and Share

    Excerpt: We argue that technology changes over time by an evolutionary process that is similar in important respects to biological evolution. The process is adaptive in the sense that technologies are selected because of their specific adaptive value and not at random, but this adaptive evolutionary process differs from the Darwinian process of random variation followed by natural selection. We find evidence for the adaptive evolution of technology in the US patent record, specifically, the public bibliographic information of all utility patents issued in the United States from 1976 through 2010. (...)

  15. Assessing the consistency of community structure in complex networks, arXiv Next Article Bookmark and Share

    Excerpt: In this paper, we introduce scaled inclusivity, which is a method to quantify the change in community structure across networks. Scaled inclusivity evaluates the consistency of the classiffication of every node in a network independently. In addition, the method can be applied cross-sectionally as well as longitudinally.(...) We propose that scaled inclusivity may provide a useful way to quantify the change in a network's community structure.

    1. Epidemiology and social networks, Cir Cir Next Article Bookmark and Share

      Excerpt: By definition, noncommunicable diseases cannot be transmitted. However, there is recent evidence of the opposite, involving a change of scientific paradigm. We have a notion that cardiovascular diseases, cancer and diabetes are noncontagious. Actually, there are no physical mechanisms that help spread these diseases. Nevertheless, risk factors of several noncommunicable diseasesâ€"such as obesity, alcoholism and smokingâ€"are spread across populations.

  16. Synergy in spreading processes: from exploitative to explorative foraging strategies, arXiv Next Article Bookmark and Share

    Abstract: An epidemiological model which incorporates synergistic effects that allow the infectivity and/or susceptibility of hosts to be dependent on the number of infected neighbours is proposed. Constructive synergy induces an exploitative behaviour which results in a rapid invasion that infects a large number of hosts. Interfering synergy leads to a slower and sparser explorative foraging strategy that traverses larger distances by infecting fewer hosts. The model can be mapped to a dynamical bond-percolation with spatial correlations that affect the mechanism of spread but do not influence the critical behaviour of epidemics.

  17. Shift of percolation thresholds for epidemic spread between static and dynamic small-world networks, Eur. Phys. J. B Next Article Bookmark and Share

    Excerpt: The study compares the epidemic spread on static and dynamic small-world networks. (...) We find a significant lowering of percolation thresholds on the dynamic network (...). The result shows the behaviour of the epidemic on dynamic network is that of a static small world with the number of shortcuts increased by 20.7±1.4 %, while the overall qualitative behaviour stays the same. (...) For both dynamic and static small worlds we observe suppression of the average epidemic size dependence on network size in comparison with the finite-size scaling known for regular lattice. We also study the effect of dynamics for several rewiring rates relative to infectious period of the disease.

    1. Exploring Discrete Dynamics, Luniver Press Next Article Bookmark and Share

      Description:
      EXPLORING DISCRETE DYNAMICS is a comprehensive guide to studying cellular automata and discrete dynamical networks with the classic software Discrete Dynamics Laboratory (DDLab), widely used in research and education. These collective networks are at the core of complexity and emergent self-organisation. With interactive graphics, DDLab is able to explore a huge diversity of behaviour, mostly terra incognita -- space-time patterns, and basins of attraction -- mathematical objects representing the convergent flow in state-space. Applications range within physics, mathematics, biology, cognition, society, economics and computation, and more specifically in neural and genetic networks, artificial life, and theories of memory.

    3. The Beginning of Infinity: Explanations That Transform the World, Viking Adult Next Article Bookmark and Share

      Summary:
      In his previous book, The Fabric of Reality, Deutsch describe the four deepest strands of existing knowledge-the theories of evolution, quantum physics, knowledge, and computation-arguing jointly they reveal a unified fabric of reality. In this new book, he applies that worldview to a wide range of issues and unsolved problems, from creativity and free will to the origin and future of the human species. Filled with startling new conclusions about human choice, optimism, scientific explanation, and the evolution of culture, The Beginning of Infinity is a groundbreaking book that will become a classic of its kind.

    4. The Origins of Health and Disease, Cambridge University Press Next Article Bookmark and Share

      Summary:
      Chronic fatigue syndrome and repetitive strain injury are diseases or syndromes that cannot be explained in terms of a physiological abnormality. Hyland proposes that there is a currently unrecognised type of illness which he calls 'dysregulatory disease'. He shows how such diseases develop and how the communication and art of medicine, good nursing care, complementary medicine and psychotherapy can all act to reduce the dysregulation that leads to dysregulatory disease. Hyland creates a meta-theory of health and disease, a synthesis that incorporates the notions of mind, brain, body, and environment.

    5. Behavior Dynamics in Media-Sharing Social Networks, Cambridge University Press Next Article Bookmark and Share

      Summary:
      In large-scale media-sharing social networks, where millions of users create, share, link and reuse media content, there are clear challenges in protecting content security and intellectual property, and in designing scalable and reliable networks capable of handling high levels of traffic. This comprehensive resource demonstrates how game theory can be used to model user dynamics and optimize design of media-sharing networks. It reviews the fundamental methodologies used to model and analyze human behavior, using examples from real-world multimedia social networks. (...)
