  1. The ten grand challenges of synthetic life, Systems and Synthetic Biology Bookmark and Share

    Abstract: The construction of artificial life is one of the main scientific challenges of the Synthetic Biology era. Advances in DNA synthesis and a better understanding of regulatory processes make the goal of constructing the first artificial cell a realistic possibility. This would be both a fundamental scientific milestone and a starting point of a vast range of applications, from biofuel production to drug design. However, several major issues might hamper the objective of achieving an artificial cell. From the bottom-up to the selection-based strategies, this work encompasses the ten grand challenges synthetic biologists will have to be aware of in order to cope with the task of creating life in the lab.

  2. Adaptive-network models of swarm dynamics, New J. Phys. Bookmark and Share

    Abstract: We propose a simple adaptive-network model describing recent swarming experiments. Exploiting an analogy with human decision making, we capture the dynamics of the model using a low-dimensional system of equations permitting analytical investigation. We find that the model reproduces several characteristic features of swarms, including spontaneous symmetry breaking, noise- and density-driven order-disorder transitions that can be of first or second order, and intermittency. Reproducing these experimental observations using a non-spatial model suggests that spatial geometry may have less of an impact on collective motion than previously thought.

  3. The Food Crises and Political Instability in North Africa and the Middle East, arXiv Bookmark and Share

    Abstract: Social unrest may reflect a variety of factors such as poverty, unemployment, and social injustice. Despite the many possible contributing factors, the timing of violent protests in North Africa and the Middle East in 2011 as well as earlier riots in 2008 coincides with large peaks in global food prices. We identify a specific food price threshold above which protests become likely. These observations suggest that protests may reflect not only long-standing political failings of governments, but also the sudden desperate straits of vulnerable populations. If food prices remain high, there is likely to be persistent and increasing global social disruption. Underlying the food price peaks we also find an ongoing trend of increasing prices. We extrapolate these trends and identify a crossing point to the domain of high impacts, even without price peaks, in 2012-2013. This implies that avoiding global food crises and associated social unrest requires rapid and concerted action.

  4. Why Philosophers Should Care About Computational Complexity, arXiv Bookmark and Share

    Abstract: One might think that, once we know something is computable, how efficiently it can be computed is a practical question with little further philosophical importance. In this essay, I offer a detailed case that one would be wrong. In particular, I argue that computational complexity theory---the field that studies the resources (such as time, space, and randomness) needed to solve computational problems---leads to new perspectives on the nature of mathematical knowledge, the strong AI debate, computationalism, the problem of logical omniscience, Hume's problem of induction, Goodman's grue riddle, the foundations of quantum mechanics, economic rationality, closed timelike curves, and several other topics of philosophical interest. I end by discussing aspects of complexity theory itself that could benefit from philosophical analysis.

  5. Alex Steffen: The shareable future of cities, TED.com Bookmark and Share

    About this talk: How can cities help save the future? Alex Steffen shows some cool neighborhood-based green projects that expand our access to things we want and need -- while reducing the time we spend in cars.

    1. Ed Boyden: A light switch for neurons, TED.com Bookmark and Share

      About this talk: Ed Boyden shows how, by inserting genes for light-sensitive proteins into brain cells, he can selectively activate or de-activate specific neurons with fiber-optic implants. With this unprecedented level of control, he's managed to cure mice of analogs of PTSD and certain forms of blindness. On the horizon: neural prosthetics.

  6. Market Instability: Why Flash Crashes Happen, NECSI Bookmark and Share

    Excerpt: The markets have been volatile recently. Various securities have experienced "mini flash crashes": they suddenly lose a large fraction of their value, and regain it just as quickly. These are smaller " but still very important " versions of what happened in May 2010, when the stock market lost and regained almost 10% of its value within minutes. This behavior suggests that the markets are unhealthy. Markets are generally considered to accurately determine the underlying value of assets in the real world. During a flash crash, the price is determined by the dynamics of the market rather than by real-world value.

  7. Nest Inheritance Is the Missing Source of Direct Fitness in a Primitively Eusocial Insect, Science Bookmark and Share

    Abstract: Animals that cooperate with nonrelatives represent a challenge to inclusive fitness theory, unless cooperative behavior is shown to provide direct fitness benefits. Inheritance of breeding resources could provide such benefits, but this route to cooperation has been little investigated in the social insects. We show that nest inheritance can explain the presence of unrelated helpers in a classic social insect model, the primitively eusocial wasp Polistes dominulus. We found that subordinate helpers produced more direct offspring than lone breeders, some while still subordinate but most after inheriting the dominant position. Thus, while indirect fitness obtained through helping relatives has been the dominant paradigm for understanding eusociality in insects, direct fitness is vital to explain cooperation in P. dominulus.

    Excerpt:
    J. FLOWER/LANL
    The arXiv server in the early 1990s: a computer that helped to change the world of physics.
    This automated repository and alert system for physics preprints, at hep-th@xxx.lanl.gov, was implemented shortly before the dawn of the web era. As I e-mailed to a colleague at CERN more than a year later: 'I know nothing of WWW, what is it?' The original plan was for roughly 100 full-text article submissions every year, each stored for three months until the existing paper distribution system could catch up. By popular demand, nothing was ever deleted.

  9. A Distant Glimpse of Alien Life?, Science Bookmark and Share

    Excerpt: At current rates of discovery, astronomers say, the first potentially habitable extrasolar planet is sure to come along soon, and many others will follow. Researchers are so confident that they are already gearing up to look for Goldilocks herself. They aim not merely to identify which planets might support life but to show that some of them do.

  10. Temporal Networks, arXiv Bookmark and Share

    Excerpt: A great variety of systems in nature, society and technology can be modeled as graphs of vertices coupled by edges. The network structure, describing how the graph is wired, helps us understand, predict and optimize the behavior of dynamic systems. In many cases, however, the edges are not continuously active. As an example, in networks of communication via email, text messages, or phone calls, edges represent sequences of instantaneous or practically instantaneous contacts. (...)

  11. Universality in Bacterial Colonies, arXiv Bookmark and Share

    Excerpt: The emergent spatial patterns generated by growing bacterial colonies have been the focus of intense study in physics during the last twenty years. Both experimental and theoretical investigations have made possible a clear qualitative picture of the different structures that such colonies can exhibit, depending on the medium on which they are growing. However, there are relatively few quantitative descriptions of these patterns. In this paper, we use a mechanistically detailed simulation framework to measure the scaling exponents associated with the advancing fronts of bacterial colonies on hard agar substrata, aiming to discern the universality class to which the system belongs. We show that the universal behavior exhibited by the colonies can be much richer than previously reported, (…)

  12. The Lehman Brothers effect and bankruptcy cascades, Eur. Phys. J. B Bookmark and Share

    Excerpt: Inspired by the bankruptcy of Lehman Brothers and its consequences on the global financial system, we develop a simple model in which the Lehman default event is quantified as having an almost immediate effect in worsening the credit worthiness of all financial institutions in the economic network. (…) The existence of a global phase transition, between paramagnetic and ferromagnetic phases, explains the large susceptibility of the system to negative shocks. We show that bailing out the first few defaulting firms does not solve the problem, but does have the effect of alleviating considerably the global shock (…) This beneficial effect is the counterpart of the large vulnerability of the system of coupled firms, which are both the direct consequences of the collective self-organized endogenous behaviors of the credit ratings of the firms in our economic network.

  13. In retrospect: The Lorax, Nature Bookmark and Share

    Excerpt: Thousands of children have learned about environmental destruction from the The Lorax, Seuss's tale of ecological ruin brought on by greed. The book still resonates: Universal Studios is due to release a feature-length animation of it next year. It packs in a lot of sophisticated concepts for a picture book, from the interconnectedness of ecosystems to the effects of industrial pollutants on freshwater systems. There is even a trophic cascade " a shift in top predators that triggers changes through a food chain. And what initially seems like a simplistic take on environmental policy " industry bad, activists good " turns out to be more subtle. The hero does not save the day; that task falls to the next generation. This downbeat, if realistic, plot arc makes me hesitant about introducing the book to my young daughter.

  14. Regenerative medicine: Bespoke cells for the human brain, Nature Bookmark and Share

    Excerpt: A major goal for biomedical researchers has been to repair damaged cells and tissues by reinitiating the body's developmental mechanisms. In this respect, the use of embryonic stem cells " and of induced pluripotent stem cells, which are generated by reprogramming differentiated adult cells " has seemed promising. But these cells come with various problems, including ethical concerns, and potential tumorigenicity and rejection by the host immune system. Three papers in this issue describe the direct conversion of neurons from skin fibroblast cells. There is hope, although no compelling evidence, that neurons generated in this way might be superior to those generated from induced pluripotent stem cells, thereby sidestepping the problems of using such cells

  15. Structure-preserving model reduction of large-scale logistics networks, Eur. Phys. J. B Bookmark and Share

    Excerpt: We investigate the problem of model reduction with a view to large-scale logistics networks, specifically supply chains. Such networks are modeled by means of graphs, which describe the structure of material flow. An aim of the proposed model reduction procedure is to preserve important features within the network. As a new methodology we introduce the LogRank as a measure for the importance of locations, which is based on the structure of the flows within the network. (…)

  16. Metabolism: Hungry cells eat from within, Nature Bookmark and Share

    Excerpt: When food is scarce, some brain cells begin to devour themselves, activating an appetite-stimulating molecule in the process.
    A brain region called the hypothalamus contains neurons that regulate feeding in response to nutritional signals. (…) found that these neurons cannibalize their own organelles, proteins and lipid stores " a process known as autophagy " when starved of nutrients. This liberates fatty acids that cause the cells to express higher levels of an appetite-stimulating compound called agouti-related peptide.

  17. Agent-based modeling of intracellular transport, Eur. Phys. J. B Bookmark and Share

    Excerpt: We develop an agent-based model of the motion and pattern formation of vesicles. These intracellular particles can be found in four different modes of (undirected and directed) motion and can fuse with other vesicles. While the size of vesicles follows a log-normal distribution that changes over time due to fusion processes, their spatial distribution gives rise to distinct patterns. Their occurrence depends on the concentration of proteins which are synthesized based on the transcriptional activities of some genes. (…)

  18. Ecosystems with mutually exclusive interactions self-organize to a state of high diversity, arXiv Bookmark and Share

    Excerpt: Ecological systems comprise an astonishing diversity of species that cooperate or compete with each other forming complex mutual dependencies. The minimum requirements to maintain a large species diversity on long time scales are in general unknown. Using lichen communities as an example, we propose a model for the evolution of mutually excluding organisms that compete for space. (…)

    1. Evolutionary and Population Dynamics: A Coupled Approach, arXiv Bookmark and Share

      Abstract: We study the interplay of population growth and evolutionary dynamics using a stochastic model based on birth and death events. In contrast to the common assumption of an independent population size, evolution can be strongly affected by population dynamics in general. Especially for fast reproducing microbes which are subject to selection, both types of dynamics are often closely intertwined. We illustrate this by considering different growth scenarios. Depending on whether microbes die or stop to reproduce (dormancy), qualitatively different behaviors emerge. For cooperating bacteria, a permanent increase of costly cooperation can occur. Even if not permanent, cooperation can still increase transiently due to demographic fluctuations. We validate our analysis via stochastic simulations and analytic calculations. In particular, we derive a condition for an increase in the level of cooperation.

    1. The Nature of Computation, Oxford University Press Bookmark and Share

      Summary:
      Computational complexity is one of the most beautiful fields of modern mathematics, and it is increasingly relevant to other sciences ranging from physics to biology. But this beauty is often buried underneath layers of unnecessary formalism, and exciting recent results like interactive proofs, cryptography, and quantum computing are usually considered too "advanced" to show to the typical student. The aim of this book is to bridge both gaps by clearly explaining the deep ideas of theoretical computer science, making them accessible to non computer scientists and to computer scientists who finally want to understand what their formalisms are actually telling.

    2. Harnessed: How Language and Music Mimicked Nature and Transformed Ape to Man, BenBella Books Bookmark and Share

      Summary:
      Cognitive scientist Changizi demonstrates that human speech has been very specifically "designed" to harness the sounds of nature, sounds we've evolved over millions of years to readily understand. Long before humans evolved, mammals have learned to interpret the sounds of nature to understand both threats and opportunities. Our speech-regardless of language-is very clearly based on the sounds of nature. Even more fascinating, Changizi shows that music itself is based on natural sounds. Music-seemingly one of the most human of inventions-is literally built on sounds and patterns of sound that have existed since the beginning of time.

    3. The Wild Life of Our Bodies: Predators, Parasites, and Partners That Shape Our Evolution, Harper Bookmark and Share

      Summary:
      We evolved in a wilderness of parasites and mutualists, but we no longer see ourselves as being part of nature and the broader community of life. In the name of progress and clean living, we scrub much of nature off our bodies and try to remove whole kinds of life (parasites, bacteria) to allow ourselves to live free of wild danger. While "clean living" has benefited us in some ways, it has also made us sicker in others. Diabetes, allergies, anxiety disorders are increasingly plaguing bodies that have been removed from the ecological context in which they existed for millennia.

    5. Desarrollo: la odisea del organismo, CopIt Arxives Bookmark and Share

      Abstract:
      En años recientes la biología evolutiva y del desarrollo se ha encontrado ante el resurgimiento, basado en evidencia relativamente nueva, de ideas que se creían ya descartadas. Se ha hallado también ante datos de genética molecular, genómica, epigenética, etc., que han obligado a generar modelos más integrativos, y que han dado lugar a teorías nuevas. De la misma manera, todo esto ha llevado a replantear la manera en que entendemos cómo surgen y se modifican las formas de los seres vivos durante su vida y a lo largo de la evolución. Así, la biología, y en particular el estudio del desarrollo y evolución de los seres vivos, parece estar en una etapa de cambio que promete avances relevantes. En este libro se revisan algunas de estas ideas que prometen el surgimiento de una nueva biología del desarrollo.
