  1. Building a Cell, Nature Next Article

    Excerpts: The living cell is a self-organizing, self-replicating, environmentally responsive machine of staggering complexity. The instructions for this complexity are contained within the cell's genetic code, but how this information is accessed, read and interpreted is influenced by development and differentiation. (...) This Insight offers a hint of the most exciting research on the regulation of cellular organization and function.

  2. Mutational robustness can facilitate adaptation, Nature Next Article

    Excerpt: Robustness seems to be the opposite of evolvability. If phenotypes are robust against mutation, we might expect that a population will have difficulty adapting to an environmental change, as several studies have suggested1, 2, 3, 4. However, other studies contend that robust organisms are more adaptable5, 6, 7, 8. A quantitative understanding of the relationship between robustness and evolvability will help resolve these conflicting reports and will clarify outstanding problems in molecular and experimental evolution, evolutionary developmental biology and protein engineering. Here we demonstrate, using a general population genetics model, that mutational robustness can either impede or facilitate adaptation, depending on the population size, the mutation rate and the structure of the fitness landscape.

  3. A synchronized quorum of genetic clocks, Nature Next Article

    Excerpt: The engineering of genetic circuits with predictive functionality in living cells represents a defining focus of the expanding field of synthetic biology. This focus was elegantly set in motion a decade ago with the design and construction of a genetic toggle switch and an oscillator, with subsequent highlights that have included circuits capable of pattern generation, noise shaping, edge detection and event counting. Here we describe an engineered gene network with global intercellular coupling that is capable of generating synchronized oscillations in a growing population of cells.

  4. The Oxford Scenarios: Beyond the Financial Crisis, Oxford SaĂŻd Business School Next Article

    Summary: A new set of Oxford scenarios aims to look beyond the current financial crisis to a deeper reflection about risk, uncertainty and the way we manage our world. Using the current financial crisis as a starting point, The Oxford Scenarios: Beyond the Financial Crisis, examines the underlying assumptions and worldviews that have allowed the current situation to unfold. By developing two possible stories of how the world can move past the credit crunch and forward into the future, these scenarios aim to spur new ways of thinking and a new approach to the actions that are taken in the present.

  5. Crisis in Haiti: Where Do We Go from Here?, Knowledge@Wharton Next Article

    Summary: The earthquake that rocked Haiti last week has caused unimaginable death and destruction, a reminder that catastrophes are usually unforeseeable and therefore almost impossible to prepare for. Can any country or region of the world, rich or poor, take meaningful steps to avoid the destruction caused by catastrophes ranging from earthquakes and hurricanes to terrorist attacks and pandemics? Knowledge@Wharton asked professors Howard Kunreuther and Michael Useem, authors of a new book titled, Learning from Catastrophes: Strategies for Reaction and Response, and Morris A. Cohen to talk about the situation in Haiti and the challenges of dealing with such crises.

  6. Slime Mold Proves to Be a Brainy Blob, New York Times Next Article

    Excerpt:
    Science/AAAS, In 26 hours, slime mold built a tubular network after 36 bits of food were arranged like Tokyo and its environs
    Researchers in Japan have shown that a slime mold can design a network that is as efficient as one developed by humans over many years: the Tokyo rail system. Furthermore, the slime mold can build its network in a day. A slime mold is what scientists refer to as a single-celled amoeboid organism. When foraging for food, it spreads out as an amorphous mass and then builds tubular connections between the food sources.

    1. A life of slime, The Economist Next Article

      Excerpt: From adhesives that mimic the feet of geckos to swimsuits modelled on shark skin, biologically inspired design has taken off in recent times. Copying nature’s ideas allows people to harness the power of evolution to come up with clever products. Now a group of researchers has taken this idea a step further by using an entire living organismâ€"a slime mouldâ€"to solve a complex problem. In this case, the challenge was to design an efficient rail network for the city of Tokyo and its outlying towns.

    2. Rules for Biologically Inspired Adaptive Network Design, Science Next Article

      Abstract: Transport networks are ubiquitous in both social and biological systems. Robust network performance involves a complex trade-off involving cost, transport efficiency, and fault tolerance. Biological networks have been honed by many cycles of evolutionary selection pressure and are likely to yield reasonable solutions to such combinatorial optimization problems. Furthermore, they develop without centralized control and may represent a readily scalable solution for growing networks in general. We show that the slime mold Physarum polycephalum forms networks with comparable efficiency, fault tolerance, and cost to those of real-world infrastructure networksâ€"in this case, the Tokyo rail system. The core mechanisms needed for adaptive network formation can be captured in a biologically inspired mathematical model that may be useful to guide network construction in other domains.

  7. Evolution of Adaptive Behaviour in Robots by Means of Darwinian Selection, PLoS Biol Next Article

    Excerpt: Ever since Cicero's De Natura Deorum ii.34., humans have been intrigued by the origin and mechanisms underlying complexity in nature. Darwin suggested that adaptation and complexity could evolve by natural selection acting successively on numerous small, heritable modifications. But is this enough? Here, we describe selected studies of experimental evolution with robots to illustrate how the process of natural selection can lead to the evolution of complex traits such as adaptive behaviours.

  8. Phylogenies reveal new interpretation of speciation and the Red Queen, Nature Next Article

    Excerpts: The Red Queen1 describes a view of nature in which species continually evolve but do not become better adapted. (...) This model predicts a constant rate of speciation, and provides a new interpretation of the Red Queen: the metaphor of species losing a race against a deteriorating environment is replaced by a view linking speciation to rare stochastic events that cause reproductive isolation.

  9. On the Universality of Zipf's Law, arXiv Next Article

    Abstract: Zipf's law is the most common statistical distribution displaying scaling behavior. Cities, populations or firms are just examples of this seemingly universal law. Although many different models have been proposed, no general theoretical explanation has been shown to exist for its universality. Here we show that Zipf's law is, in fact, an inevitable outcome of a very general class of stochastic systems. Borrowing concepts from Algorithmic Information Theory, our derivation is based on the properties of the symbolic sequence obtained through successive observations over a system with an unbounded number of possible states. Specifically, we assume that the complexity of the description of the system provided by the sequence of observations is the one expected for a system evolving to a stable state between order and disorder. This result is obtained from a small set of mild, physically relevant assumptions. The general nature of our derivation and its model-free basis would explain the ubiquity of such a law in real systems.

  10. Computing Networks: A General Framework to Contrast Neural and Swarm Architectures, arXiv Next Article

    Abstract: Computing Networks (CNs) are defined. These are used to generalize neural and swarm architectures, namely artificial neural networks, ant colony optimization, and particle swarm optimization. The description of these architectures as CNs allows their comparison, distinguishing which properties enable them to perform complex computations and exhibit complex cognitive abilities. In this context, the most relevant characteristics of CNs are the existence multiple dynamical and functional scales.

  11. Protein Interaction Networksâ€"More Than Mere Modules, PLoS Comput Biol Next Article

    Excerpt: In this contribution, we show that extrapolating this concept of cohesively linked clusters of proteins as modules to the scale of the entire PIN inevitably misses important and functionally relevant structure inherent in the network. As an alternative, we introduce a novel way of decomposing a network into functional roles and show that this represents network structure and function more efficiently. This finding should have a profound impact on all module assisted methods of protein function prediction and should shed new light on how functional modules can be represented in molecular interaction networks in general.

  12. The real holes in climate science, Nature Next Article

    Summary: Like any other field, research on climate change has some fundamental gaps, although not the ones typically claimed by sceptics. Quirin Schiermeier takes a hard look at some of the biggest problem areas.

  13. How Synchronization Protects from Noise, PLoS Comput Biol Next Article

    Excerpt: Synchronization phenomena are pervasive in biology, creating collective behavior out of local interactions between neurons, cells, or animals. On the other hand, many of these systems function in the presence of large amounts of noise or disturbances, making one wonder how meaningful behavior can arise in these highly perturbed conditions. In this paper we show mathematically, in a general context, that synchronization is actually a means to protect interconnected systems from effects of noise and disturbances.

  14. Human strategy updating in evolutionary games, arXiv Next Article

    Excerpt: Evolutionary game dynamics describes not only frequency dependent genetical evolution, but also cultural evolution in humans. In this context, successful strategies spread by imitation. It has been shown that the details of strategy update rules can have a crucial impact on evolutionary dynamics in theoretical models and e.g. significantly alter the level of cooperation in social dilemmas. But what kind of strategy update rules can describe imitation dynamics in humans?

    1. Promotion of cooperation induced by nonuniform payoff allocation in spatial public goods game, Eur. Phys. J. B Next Article

      Abstract: A nonuniform payoff allocation mechanism is proposed for spatial public goods games where individuals are nodes on a scale-free network. Each individual is assigned a weight kiα, where ki is the degree of individual i and α is an adjustable parameter that controls the degree of diversity in individuals' profits. During the evolution progress, the allocation of payoff on individual i is assumed to be proportional to its weight. Individuals synchronously update their strategies according to the stochastic rule with a fixed noise level. It is found that there exists an optimal value of α which yields the highest level of cooperation. Other pertinent quantities, including the payoff and the probability of finding a node playing as cooperator versus the degree, are also investigated computationally and analytically. Our results suggest that a suitable degree of diversity among individuals can promote the emergence of cooperation.

  15. Optimal Synchronization in Space, arXiv Next Article

    Excerpt: In this Rapid Communication we investigate spatially constrained networks that realize optimal synchronization properties. After arguing that spatial constraints can be imposed by limiting the amount of `wire' available to connect nodes distributed in space, we use numerical optimization methods to construct networks that realize different trade-offs between optimal synchronization and spatial constraints.

  16. Differentiating information transfer and causal effect, Eur. Phys. J. B Next Article

    Abstract: he concepts of information transfer and causal effect have received much recent attention, yet often the two are not appropriately distinguished and certain measures have been suggested to be suitable for both. We discuss two existing measures, transfer entropy and information flow, which can be used separately to quantify information transfer and causal information flow respectively. We apply these measures to cellular automata on a local scale in space and time, in order to explicitly contrast them and emphasize the differences between information transfer and causality. We also describe the manner in which the measures are complementary, including the conditions under which they in fact converge. We show that causal information flow is a primary tool to describe the causal structure of a system, while information transfer can then be used to describe the emergent computation on that causal structure.

  17. Altered microbe makes biofuel, Nature Next Article

    Excerpt: In a bid to overcome the drawbacks of existing biofuels, researchers have engineered a bacterium that can convert a form of raw plant biomass directly into clean, road-ready diesel.

  18. Live Coverage of Scientific Conferences Using Web Technologies, PLoS Comput Biol Next Article

    Excerpt: The Internet has become instrumental in organizing and advertising conferences. In the past few years, simple Internet-based publishing tools such as blogs have also made it possible for individuals to report and discuss conferences publicly, tasks previously reserved for established media, the organizers, or selected attending scientists. While traditional publishing-house journalism has broadly remained unchanged, many scientists are now publishing their notes on the Internet, accelerating the spread of information to interested audiences. With the increasing popularity of live blogging, conference organizers need to consider how such techniques relate to existing policies. While publication of information at some level is a primary goal of all conferences, there are diverse technological, political, and social factors associated with live blogging that organizers should consider.

    1. Streetlights and Shadows: Searching for the Keys to Adaptive Decision Making, The MIT Press Next Article

      Summary:
      Most of us would probably agree that for important decisions, we should follow certain guidelinesâ€"gather as much information as possible, compare the options, pin down the goals before getting started. But in practice we make some of our best decisions by adapting to circumstances rather than blindly following procedures. In this book, Gary Klein debunks the conventional wisdom about how to make decisions. He takes ten commonly accepted claims about decision making and shows that they are better suited for the laboratory than for life. (...)

    2. Control of Complex Systems: Structural Constraints and Uncertainty, Springer Next Article

      Summary:
      This book focuses on control design under information structure constraints, with a particular emphasis on large-scale systems. The complexity of such systems poses serious computational challenges and severely restricts the types of feedback laws that can be used in practice. This book systematically addresses the main issues, and provides a number of applications that illustrate potential design methods, most which use Linear Matrix Inequalities (LMIs), which have become a popular design tool over the past two decades.

    3. Here Be Dragons: How the Study of Animal and Plant Distributions Revolutionized Our Views of Life and the Earth, Oxford University Press Next Article

      Summary:
      Why do we find polar bears only in the Arctic and penguins only in the Antarctic? In answering these puzzles, McCarthy tells a story that encompasses two great, insightful theories that together explain the strange patterns of life across the world--evolution and plate tectonics. We find animals and plants where we do because, over time, the continents have moved, separating and uniting in a long, slow dance; because sea levels have risen, cutting off one bit of land from another; because animals and plants vary greatly in their ability to travel, and separation causes the formation of new species.

    6. The Master and His Emissary: The Divided Brain and the Making of the Western World, Yale University Press Next Article

      Summary:
      Why is the brain divided? In this book, McGilchrist draws on a vast body of recent brain research, illustrated with case histories, to reveal that the difference is profoundâ€"not just this or that function, but two whole, coherent, but incompatible ways of experiencing the world. The left hemisphere is detail oriented, prefers mechanisms to living things, and is inclined to self-interest, where the right hemisphere has greater breadth, flexibility, and generosity. This division helps explain the origins of music and language, and casts new light on the history of philosophy, as well as on some mental illnesses.
