Creation of a Bacterial Cell Controlled by a Chemically Synthesized Genome, Science
Abstract: We report the design, synthesis, and assembly of the 1.08-Mbp Mycoplasma mycoides JCVI-syn1.0 genome starting from digitized genome sequence information and its transplantation into a Mycoplasma capricolum recipient cell to create new Mycoplasma mycoides cells that are controlled only by the synthetic chromosome. The only DNA in the cells is the designed synthetic DNA sequence, including "watermark" sequences and other designed gene deletions and polymorphisms, and mutations acquired during the building process. The new cells have expected phenotypic properties and are capable of continuous self-replication.
Editor's Note: This work can be considered the first "wet" Artificial Life system. It implies increased understanding on the notion of life and offers several potential applications.
Craig Venter unveils "synthetic life", TED.com
About this talk: Craig Venter and team make a historic announcement: they've created the first fully functioning, reproducing cell controlled by synthetic DNA. He explains how they did it and why the achievement marks the beginning of a new era for science.
Molecular robots guided by prescriptive landscapes, Nature
Summary: Traditional robots need to store internal representations of their goals and environment, and to coordinate sensing and the movement of components required in response. Individual molecules are limited in their ability to store complex information, but robotic behaviour can still be realized â€" as has now been shown with DNA walkers, which can carry out a sequence of actions such as 'start', 'follow', 'turn' and 'stop' that are programmed into the DNA landscape on which the walkers move.
Editor's Note: Information can be stored within an agent or can lie on its environment.

The FuturIcT Knowledge Accelerator: Unleashing the Power of Information for a Sustainable Future, arXiv
Abstract: With our knowledge of the universe, we have sent men to the moon. We know microscopic details of objects around us and within us. And yet we know relatively little about how our society works and how it reacts to changes brought upon it. Humankind is now facing serious crises for which we must develop new ways to tackle the global challenges of humanity in the 21st century. With connectivity between people rapidly increasing, we are now able to exploit information and communication technologies to achieve major breakthroughs that go beyond the step-wise improvements in other areas. The need of a socio-economic knowledge collider was first pointed out in the OECD Global Science Forum on Applications of Complexity Science for Public Policy in Erice from October 5 to 7, 2008. Since then, many scientists have called for a large-scale ICT-based research initiative on techno-socialeconomic- environmental issues, sometimes phrased as a Manhattan-, Apollo-, or CERN-like project to study the way our living planet works in a social dimension. Due to the connotations, we use the term knowledge accelerator, here.

Gene regulation: Breaking the second genetic code, Nature
Summary: Diverse messenger RNAs, and thus proteins, can be generated from a single piece of DNA. A computational approach is helping to uncover complex combinatorial rules by which specific gene instructions are selected.
Deciphering the splicing code, Nature
Excerpt: Alternative splicing has a crucial role in the generation of biological complexity, and its misregulation is often involved in human disease. Here we describe the assembly of a â€˜splicing codeâ€™, which uses combinations of hundreds of RNA features to predict tissue-dependent changes in alternative splicing for thousands of exons. The code determines new classes of splicing patterns, identifies distinct regulatory programs in different tissues, and identifies mutation-verified regulatory sequences (...)

A formal test of the theory of universal common ancestry, Nature
Excerpt: Universal common ancestry (UCA) is a central pillar of modern evolutionary theory. As first suggested by Darwin, the theory of UCA posits that all extant terrestrial organisms share a common genetic heritage, each being the genealogical descendant of a single species from the distant past (...) the model selection tests are found to overwhelmingly support UCA irrespective of the presence of horizontal gene transfer and symbiotic fusion events. These results provide powerful statistical evidence corroborating the monophyly of all known life.
Selfish Games, Science
Excerpt: In The Calculus of Selfishness, Karl Sigmund provides a comprehensive and accessible mathematical exposition of the evolutionary game theory of selfishness. The book should prove accessible to natural and social scientists as its mathematical arguments employ intuition, geometry, and simulation with a minimum of axiomatic formality. The demands on the reader typically involve little more than linear algebra and calculus.

Crisis, Contagion and Bailouts: What's Next for the European Union?, Knowledge@Wharton
Excerpt: European financial officials finally got out in front of swift-moving market developments this week by launching a huge $960 billion (750 billion euro) financial stabilization plan -- exceeding most expectations -- to bail out Greece and ensure the viability of the European Monetary Union, at least for now. Some observers say the move prevented a potential financial meltdown in which concerns over sovereign debt defaults would have swiftly led to large-scale bank runs in some European countries. Many experts this week expected the package to continue to calm markets -- at least temporarily -- by guaranteeing most sovereign (and some private) debt in Greece, or by providing credit for other troubled member economies in the future, including Portugal, Spain and Ireland.
Principles and applications of swarm intelligence for adaptive routing in telecommunications networks, Swarm Intelligence
Excerpt: In the past few years, there has been much research on the application of swarm intelligence to the problem of adaptive routing in telecommunications networks. A large number of algorithms have been proposed for different types of networks, including wired networks and wireless ad hoc networks. In this paper, we give an overview of this research area. We address both the principles underlying the research and the practical applications that have been proposed.
Prestige Affects Cultural Learning in Chimpanzees, PLoS ONE
Excerpt: Humans follow the example of prestigious, high-status individuals much more readily than that of others, such as when we copy the behavior of village elders, community leaders, or celebrities. This tendency has been declared uniquely human, yet remains untested in other species [...] Here we report that when given opportunities to watch alternative solutions to a foraging problem performed by two different models of their own species, chimpanzees preferentially copy the method shown by the older, higher-ranking individual with a prior track-record of success.
First Person Experience of Body Transfer in Virtual Reality, PLoS ONE
Excerpt: Here we show that a first person perspective of a life-sized virtual human female body that appears to substitute the male subjects' own bodies was sufficient to generate a body transfer illusion. This was demonstrated subjectively by questionnaire and physiologically through heart-rate deceleration in response to a threat to the virtual body. This finding is in contrast to earlier experimental studies that assume visuotactile synchrony to be the critical contributory factor in ownership illusions.
Network Diversity and Economic Development, Science
Abstract: Social networks form the backbone of social and economic life. Until recently, however, data have not been available to study the social impact of a national network structure. To that end, we combined the most complete record of a national communication network with national census data on the socioeconomic well-being of communities. These data make possible a population-level investigation of the relation between the structure of social networks and access to socioeconomic opportunity. We find that the diversity of individualsâ€™ relationships is strongly correlated with the economic development of communities.
Community Structure in Time-Dependent, Multiscale, and Multiplex Networks, Science
Abstract: Network science is an interdisciplinary endeavor, with methods and applications drawn from across the natural, social, and information sciences. A prominent problem in network science is the algorithmic detection of tightly connected groups of nodes known as communities. We developed a generalized framework of network quality functions that allowed us to study the community structure of arbitrary multislice networks, which are combinations of individual networks coupled through links that connect each node in one network slice to itself in other slices. This framework allows studies of community structure in a general setting encompassing networks that evolve over time, have multiple types of links (multiplexity), and have multiple scales.

Quantifying the Ease of Scientific Discovery, arXiv
Abstract: It has long been known that scientific output proceeds on an exponential increase, or more properly, a logistic growth curve. The interplay between effort and discovery is clear, and the nature of the functional form has been thought to be due to many changes in the scientific process over time. Here I show a quantitative method for examining the ease of scientific progress, another necessary component in understanding scientific discovery. Using examples from three different scientific disciplines - mammalian species, chemical elements, and minor planets - I find the ease of discovery to conform to an exponential decay. In addition, I show how the pace of scientific discovery can be best understood as the outcome of both scientific output and ease of discovery. A quantitative study of the ease of scientific discovery in the aggregate, such as done here, has the potential to provide a great deal of insight into both the nature of future discoveries and the technical processes behind discoveries in science.
Animal Communication Helps Reveal Roots of Language, Science
Summary: An interdisciplinary gathering marks a turning point for a field historically richer in talk than data, but which now is increasingly embracing studies of animals.
Landscapes of Infection, Science
Excerpt: Infectious disease remains one of the biggest killers in developing countries. Two of them account for an enormous toll: Eleven million people live with tuberculosis (TB), and almost 250 million cases of malariaâ€"and roughly a million deaths among childrenâ€"were reported in 2008; a staggering assault on human-kind. (...) Once, we aspired to find "magic bullet" solutions to these plagues using vaccines or drugs, but we have learned that there are no cure-all or simple solutions. These pathogens have complex repertoires of genetic resources that permit them to constantly reinvent themselves and escape the pressures applied by infection-control measures. To curb these elusive targets, we, too, need a large repertoire of tools.

Punctuation effects in english and esperanto texts, Physica A
Abstract: A statistical physics study of punctuation effects on sentence lengths is presented for written texts: Alice in wonderland and Through a looking glass. The translation of the first text into esperanto is also considered as a test for the role of punctuation in defining a style, and for contrasting natural and artificial, but written, languages. Several logâ€"log plots of the sentence-lengthâ€"rank relationship are presented for the major punctuation marks. Different power laws are observed with characteristic exponents. The exponent can take a value much less than unity (ca. 0.50 or 0.30) depending on how a sentence is defined. The texts are also mapped into time series based on the word frequencies. The quantitative differences between the original and translated texts are very minutes, at the exponent level. It is argued that sentences seem to be more reliable than word distributions in discussing an author style.
Defector-accelerated cooperativeness and punishment in public goods games with mutations, arXiv
Abstract: We study the evolution of cooperation in spatial public goods games with four competing strategies: cooperators, defectors, punishing cooperators, and punishing defectors. To explore the robustness of the cooperation-promoting effect of costly punishment, besides the usual strategy adoption dynamics we also apply strategy mutations. As expected, frequent mutations create kind of well-mixed conditions, which support the spreading of defectors. However, when the mutation rate is small, the final stationary state does not significantly differ from the state of the mutation-free model, independently of the values of the punishment fine and cost. Nevertheless, the mutation rate affects the relaxation dynamics. Rare mutations can largely accelerate the spreading of costly punishment. This is due to the fact that the presence of defectors breaks the balance of power between both cooperative strategies, which leads to a different kind of dynamics.
Adaptive networks: coevolution of disease and topology, arXiv
Abstract: Adaptive networks have been recently introduced in the context of disease propagation on complex networks. They account for the mutual interaction between the network topology and the states of the nodes. Until now, existing models have been analyzed using low-complexity analytic formalisms, revealing nevertheless some novel dynamical features. However, current methods have failed to reproduce with accuracy the simultaneous time evolution of the disease and the underlying network topology. In the framework of the adaptive SIS model of Gross et al. [Gross et al., Phys. Rev. Lett. 96, 208701 (2006)], we introduce an improved compartmental formalism able to handle this coevolutionary task successfully. With this approach, we analyze the interplay and outcomes of both dynamical elements, process and structure, on adaptive networks featuring different degree distributions at the initial stage.
Structural Drift: The Population Dynamics of Sequential Learning, arXiv
Abstract: We introduce a theory of sequential causal inference in which learners in a chain estimate a structural model from their upstream teacher and then pass samples from the model to their downstream student. It extends the population dynamics of genetic drift, recasting Kimura's selectively neutral theory as a special case of a generalized drift process using structured populations with memory. We examine the diffusion and fixation properties of several drift processes and propose applications to learning, inference, and evolution. We also demonstrate how the organization of drift process space controls fidelity, facilitates innovations, and leads to information loss in sequential learning with and without memory.
The Onset of Collective Behavior in Social Amoebae, Science
Abstract: In the social amoebae Dictyostelium discoideum, periodic synthesis and release of extracellular cyclic adenosine 3',5'-monophosphate (cAMP) guide cell aggregation and commitment to form fruiting bodies. It is unclear whether these oscillations are an intrinsic property of individual cells or if they exist only as a population-level phenomenon. Here, we showed by live-cell imaging of intact cell populations that pulses originate from a discrete location despite constant exchange of cells to and from the region. In a perfusion chamber, both isolated single cells and cell populations switched from quiescence to rhythmic activity depending on the concentration of extracellular cAMP. A quantitative analysis showed that stochastic pulsing of individual cells below the threshold concentration of extracellular cAMP plays a critical role in the onset of collective behavior.
Decentralize, adapt and cooperate, Nature
Excerpt: We have identified several features of natural systems that we believe would translate well to human security. These are common patterns and behaviours in natural systems that have probably evolved independently many times and have proved successful against a range of threats. We have analysed many human situations that would benefit from natural security, and several that already have. Although other researchers have used ecological models to analyse patterns of violence during conflicts, we believe that using natural and social-science methods to look at the broad spectrum of human-security concerns will lead to more adaptable and effective defences.

Summary: This heavily illustrated book collects in one source most of the mathematically simple systems of differential equations whose solutions are chaotic. It includes the historically important systems of van der Pol, Duffing, Ueda, Lorenz, Rossler, and many others, but it goes on to show that there are many other systems that are simpler and more elegant. Many of these systems have been only recently discovered and are not widely known. Most cases include plots of the attractor and calculations of the spectra of Lyapunov exponents. Some important cases include graphs showing the route to chaos. (...)

What's Luck Got to Do with It?: The History, Mathematics, and Psychology of the Gambler's Illusion, Princeton University Press
Summary: Why do so many gamblers risk it all when they know the odds of winning are against them? Why do they believe dice are "hot" in a winning streak? Why do we expect heads on a coin toss after several flips have turned up tails? What's Luck Got to Do with It? takes a lively and eye-opening look at the mathematics, history, and psychology of gambling to reveal the most widely held misconceptions about luck. It exposes the hazards of feeling lucky, and uses the mathematics of predictable outcomes to show when our chances of winning are actually good. (...)
Summary: The book is a compilation of selected papers from the conference on Physics and Control 2009, presenting a unified perspective underlying the thematics and strategies related to the control of physical systems with emerging applications in physics, engineering, chemistry, biology and other natural sciences. The selected papers reflect the state-of-the-art of the more advanced theoretical and practical studies in the field of control of complex systems. The contributions provide a comprehensive view on some selected topics of particular importance at the disciplinary borderline between Physics and Control.

One of the main goals of the ASSYST Coordination Action is to promote Complex Systems for Socially Intelligent ICT (COSI-ICT) and, more generally, Complex Systems (CS) Science in Europe and Worldwide. We do this by communicating widely with scientists, policy makers, and business people, and by showcasing success stories of CS applications.
