What Is Epigenetics?, Science
Excerpt: The cells in a multicellular organism have nominally identical DNA sequences (and therefore the same genetic instruction sets), yet maintain different terminal phenotypes. This nongenetic cellular memory, which records developmental and environmental cues (and alternative cell states in unicellular organisms), is the basis of epi-(above)â"genetics.
Diffusion of Competing Innovations: The Effects of Network Structure on the Provision of Healthcare, JASSS
Excerpt: Medical innovations, in the form of new medication or other clinical practices, evolve and spread through health care systems, impacting on the quality and standards of health care provision, which is demonstrably heterogeneous by geography. Our aim is to investigate the potential for the diffusion of innovation to influence health inequality and overall levels of recommended care.
Is Life Impossible? Information, Sex, and the Origin of Complex Organisms, Evolution
Excerpt: The earliest organisms are thought to have had high mutation rates. It has been asserted that these high mutation rates would have severely limited the information content of early genomes. This has led to a well-known âparadoxâ because, in contemporary organisms, the mechanisms that suppress mutations are quite complex and a substantial amount of information is required to construct these mechanisms. The paradox arises because it is not clear how efficient error-suppressing mechanisms could have evolved, and thus allowed the evolution of complex organisms, at a time when mutation rates were too high to permit the maintenance of very substantial amounts of information within genomes. Here, we use concepts from the formal theory of information to calculate the amount of genomic information that can be maintained. (...)
Higher rates of sex evolve in spatially heterogeneous environments, Nature
Excerpt: The evolution and maintenance of sexual reproduction has puzzled biologists for decades (...) Here we use the rotifer, Brachionus calyciflorus, which is capable of both sexual and asexual reproduction, to test recent theory predicting that there is more opportunity for sex to evolve in spatially heterogeneous environments. (...)
A map of human genome variation from population-scale sequencing, Nature
Excerpt: The 1000 Genomes Project aims to provide a deep characterization of human genome sequence variation as a foundation for investigating the relationship between genotype and phenotype. Here we present results of the pilot phase of the project, designed to develop and compare different strategies for genome-wide sequencing with high-throughput platforms.
Diversity of Human Copy Number Variation and Multicopy Genes, Science
Excerpt: Copy number variants affect both disease and normal phenotypic variation, but those lying within heavily duplicated, highly identical sequence have been difficult to assay. By analyzing short-read mapping depth for 159 human genomes, we demonstrated accurate estimation of absolute copy number for duplications as small as 1.9 kilobase pairs, ranging from 0 to 48 copies. (...) These data identify human-specific expansions in genes associated with brain development, reveal extensive population genetic diversity, and detect signatures consistent with gene conversion in the human species. Our approach makes ~1000 genes accessible to genetic studies of disease association.
Gero Miesenboeck reengineers a brain, TED.com
About this talk: In the quest to map the brain, many scientists have attempted the incredibly daunting task of recording the activity of each neuron. Gero Miesenboeck works backward -- manipulating specific neurons to figure out exactly what they do, through a series of stunning experiments that reengineer the way fruit flies percieve light.
David Bismark: E-voting without fraud, TED.com
About this talk: David Bismark demos a new system for voting that contains a simple, verifiable way to prevent fraud and miscounting -- while keeping each person's vote secret.
R.A. Mashelkar: Breakthrough designs for ultra-low-cost products, TED.com
About this talk: Engineer RA Mashelkar shares three stories of ultra-low-cost design from India that use bottom-up rethinking, and some clever engineering, to bring expensive products (cars, prosthetics) into the realm of the possible for everyone.
Collective motion, arXiv
Excerpt: We review the observations and the basic laws describing the essential aspects of collective motion -- being one of the most common and spectacular manifestation of coordinated behavior. Our aim is to provide a balanced discussion of the various facets of this highly multidisciplinary field, including experiments, mathematical methods and models for simulations, so that readers with a variety of background could get both the basics and a broader, more detailed picture of the field. The observations we report on include systems consisting of units ranging from macromolecules through metallic rods and robots to groups of animals and people. (...)

Excerpts: In this paper, we approach the idea of group cognition from the perspective of the âextended mindâ thesis, as a special case of the more general claim that systems larger than the individual human, but containing that human, are capable of cognition ([Clark, 2008] and [Clark and Chalmers, 1998]). Instead of deliberating about âthe mark of the cognitiveâ (Adams & Aizawa, 2008), our discussion of group cognition is tied to particular cognitive capacities. We review recent studies of group problem solving and group memory which reveal that specific cognitive capacities that are commonly ascribed to individuals are also aptly ascribed at the level of groups. (...) Group cognition is thus an emergent phenomenon in the sense of Wimsatt (1986). (...)

Unbounding the Mind, Science
Excerpt: Where is the mind? "In the head" or "in the brain," most people might respond. The philosopher Gilbert Ryle gave a different answer:
The statement "the mind is in its own place," as theorists might construe it, is not true, for the mind is not even a metaphorical "place." On the contrary, the chessboard, the platform, the scholar's desk, the judge's bench, the lorry, the driver's seat, the studio and the football field are among its places. Recently, this idea of the mind not being confined to the head has been reinvigorated by philosophers and cognitive scientists, who see the mind as "spreading out" or "extending" into the world.

Engineering of a synthetic electron conduit in living cells, PNAS
Excerpt: Engineering efficient, directional electronic communication between living and nonliving systems has the potential to combine the unique characteristics of both materials for advanced biotechnological applications. However, the cell membrane is designed by nature to be an insulator, restricting the flow of charged species; therefore, introducing a biocompatible pathway for transferring electrons across the membrane without disrupting the cell is a significant challenge. Here we describe a genetic strategy to move intracellular electrons to an inorganic extracellular acceptor along a molecularly defined route.
Friends With Cognitive Benefits: Mental Function Improves After Certain Kinds of Socializing, ScienceDaily
Excerpts: Talking with other people in a friendly way can make it easier to solve common problems, a new University of Michigan study shows. But conversations that are competitive in tone, rather than cooperative, have no cognitive benefits. "This study shows that simply talking to other people, the way you do when you're making friends, can provide mental benefits," said (ï¿½). For the study, the researchers examined the impact of brief episodes of social contact on one key component of mental activity -- executive function. This type of cognitive function includes working memory, self-monitoring, (ï¿½) all of which are essential in solving common life problems. (ï¿½)
Genome size, self-organization and DNA's dark matter, Complexity
Abstract: Chromosomes exhibit several features indicating that its spatiotemporal dynamics is self-organized. It has been recently suggested that a negative correlation between genome size and mean chromosome number would also be a fingerprint of selforganization, related to how human language is organized at the level of words and syllables. However, the vast dominance of non-coding DNA in eukaryotic genomes should prevent an interpretation of genome/chromosome size based on functional trade-offs related to information storage and transmission. Moreover, the reported negative correlation is shown to be an inevitable consequence of the definitions of chromosome and genome length and it is thus unrelated to any type of special generative process.
Universal Robotic Gripper based on the Jamming of Granular Material, arXiv
Excerpt: Gripping and holding of objects are key tasks for robotic manipulators. The development of universal grippers able to pick up unfamiliar objects of widely varying shape and surface properties remains, however, challenging. (...) Here we demonstrate a completely different approach to a universal gripper. Individual fingers are replaced by a single mass of granular material that, when pressed onto a target object, flows around it and conforms to its shape. Upon application of a vacuum the granular material contracts and hardens quickly to pinch and hold the object without requiring sensory feedback. (...) We delineate three separate mechanisms, friction, suction and interlocking, that contribute to the gripping force. Using a simple model we relate each of them to the mechanical strength of the jammed state. This opens up new possibilities for the design of simple, yet highly adaptive systems that excel at fast gripping of complex objects.

Contract theory for the evolution of cooperation: The right incentives attract the right partner, Journal of Theoretical Biology
Excerpt: Partner choice is a critical stage of many biological interactions, from mating to cooperation [...] I show that in a game with asymmetric information without signalling, imposing a deliberate cost for establishing the interaction allows the non-informed individual to attract the right partner if the cost induces only high quality individuals to accept the interaction.
Excerpt: We analyze the influence of the update dynamics on symmetric 2-player evolutionary games, which are among the most used tools to study the emergence of cooperation in populations of interacting agents.
Excerpt: We study a condition of favoring cooperation in a Prisoner's Dilemma game on complex networks. There are two kinds of players: cooperators and defectors. Cooperators pay a benefit b to their neighbors at a cost c, whereas defectors only receive a benefit. The game is a death-birth process with weak selection. Although it has been widely thought that b/c =k is a condition of favoring cooperation , we find that b/c =k nn is the condition. We also show that ...
How Wealth Accumulation Can Promote Cooperation, PLoS ONE 5(10)
Excerpt: Here, we report the emergence, survival, and frequent domination of cooperation in a world characterized by selfishness and a strong temptation to defect, when individuals can accumulate wealth. In particular, we study games with local adaptation such as the prisoner's dilemma, to which we add heterogeneity in payoffs. In our model, agents accumulate wealth and invest some of it in their interactions. The larger the investment, the more can potentially be gained or lost, so that present gains affect future payoffs. We find that cooperation survives for a far wider range of parameters than without wealth accumulation and, even more strikingly, that it often dominates defection.
The Origins Of Modern Biodiversity On Land, Phil. Trans. B
Excerpt: Comparative studies of large phylogenies of living and extinct groups have shown that most biodiversity arises from a small number of highly species-rich clades. To understand biodiversity, it is important to examine the history of these clades on geological time scales. This is part of a distinct ï¿½phylogenetic expansionï¿½ view of macroevolution, and contrasts with the alternative, non-phylogenetic ï¿½equilibriumï¿½ approach to the history of biodiversity. The latter viewpoint focuses on density-dependent models in which all life is described by a single global-scale model, and a case is made here that this approach may be less successful at representing the shape of the evolution of life (ï¿½).
Learning In A Game Context: Strategy Choice By Some Keeps Learning From Evolving In Others, Proc. B
Excerpts: Behavioural decisions in a social context commonly have frequency-dependent outcomes and so require analysis using evolutionary game theory. Learning provides a mechanism for tracking changing conditions and it has frequently been predicted to supplant fixed behaviour in shifting environments; yet few studies have examined the evolution of learning specifically in a game-theoretic context. We present a model that examines the evolution of learning in a frequency-dependent context created by a producerï¿½scrounger game, where producers search for their own resources and scroungers usurp the discoveries of producers. (ï¿½) We find that learning provides an initial advantage but never evolves to fixation. (ï¿½)
Excerpt: In many, if not most, elections, several different seats must be filled, so that a group of candidates, or an assembly, is selected. Typically in these elections, voters cast their ballots on a seat-by-seat basis. We show that these seat-by-seat procedures are efficient only under extreme conditions.
Excerpt: In Conflict Resolution situations where two parties with opposed preferences need to make
a number of decisions simultaneously,we propose a simple mechanism that endows agents with
a certain number of votes that can be distributed freely across issues. We test its properties using controlled laboratory experiments. The subjects almost reach the welfare predicted by the theory even when their behaviour is far from equilibrium. The fact that deviations from equilibrium do not do much damage to its welfare properties is a further argument in favour of the use of this mechanism in the real world.
The Roundtable: An Abstract Model of Conversation Dynamics, JASSS
Abstract: Is it possible to abstract a formal mechanism originating schisms and governing the size evolution of social conversations? In this work we propose a constructive solution to this problem: an abstract model of a generic N-party turn-taking conversation. The model develops from simple yet realistic assumptions derived from experimental evidence, abstracts from conversation content and semantics while including topological information, and is driven by stochastic dynamics. We find that a single mechanism, namely the dynamics of conversational party's individual fitness as related to conversation size, controls the development of the self-organized schisming phenomenon. Potential generalizations of the model - including individual traits and preferences, memory effects and more elaborated conversational topologies - may find important applications also in other fields of research, where dynamically-interacting and networked agents play a fundamental role.
Complex adaptive systems and game theory: An unlikely union, Complexity
Abstract: A Complex Adaptive System is a collection of autonomous, heterogeneous agents, whose behavior is defined with a limited number of rules. A Game Theory is a mathematical construct that assumes a small number of rational players who have a limited number of actions or strategies available to them. The CAS method has the potential to alleviate some of the shortcomings of GT. On the other hand, CAS researchers are always looking for a realistic way to define interactions among agents. GT offers an attractive option for defining the rules of such interactions in a way that is both potentially consistent with observed real-world behavior and subject to mathematical interpretation. This article reports on the results of an effort to build a CAS system that utilizes GT for determining the actions of individual agents.
Quantum Game of Life, arXiv
Abstract: We introduce a quantum version of the Game of Life, and we show that it displays signatures of complex behavior similar to the classical one, and that quantum evolution creates more complexity, in terms of diversity, with respect to the classical one. This new quantum model can be used to address important questions on the emergency of complexity in a quantum world, thermalization and of the existence of self organization in many body quantum systems.
How the Dimension of Space Affects the Products of Pre-Biotic Evolution: The Spatial Population Dynamics of Structural Complexity and The Emergence of Membranes, arXiv
Excerpt: We show that autocatalytic networks of epsilon-machines and their population dynamics differ substantially between spatial (geographically distributed) and nonspatial (panmixia) populations. Generally, regions of spacetime-invariant autocatalytic networks---or domains---emerge in geographically distributed populations. These are separated by functional membranes of complementary epsilon-machines that actively translate between the domains and are responsible for their growth and stability. (...)
Network Science: Complexity in Nature and Technology, Springer
Summary: Network Science is the emerging field concerned with the study of large, realistic networks. This interdisciplinary endeavor, focusing on the patterns of interactions that arise between individual components of natural and engineered systems, has been applied to data sets from activities as diverse as biological experiments, online trading information, smart-meter utility supplies, and pervasive telecommunications and surveillance technologies. This unique reference provides a fascinating insight into the state of the art in network science, highlighting the commonality across very different areas of application and the ways in which each area can be advanced by injecting ideas and techniques from another.
Complex Networks: Structure, Robustness and Function, Cambridge University Press
Summary: Examining important results and analytical techniques, this graduate-level textbook is a step-by-step presentation of the structure and function of complex networks. Using a range of examples, from the stability of the internet to efficient methods of immunizing populations, and from epidemic spreading to how one might efficiently search for individuals, this textbook explains the theoretical methods that can be used, and the experimental and analytical results obtained in the study and research of complex networks. Giving detailed derivations of many results in complex networks theory, this is an ideal text to be used by graduate students entering the field.
Lectures in Supercomputational Neuroscience: Dynamics in Complex Brain Networks, Springer
Summary: Computational Neuroscience is a burgeoning field of research where only the combined effort of neuroscientists, biologists, psychologists, physicists, mathematicians, computer scientists, engineers and other specialists, e.g. from linguistics and medicine, seem to be able to expand the limits of our knowledge. The present volume is an introduction, largely from the physicists' perspective, to the subject matter with in-depth contributions by system neuroscientists. A conceptual model for complex networks of neurons is introduced that incorporates many important features of the real brain, such as various types of neurons, various brain areas, inhibitory and excitatory coupling and the plasticity of the network.
The Colours of Infinity: The Beauty and Power of Fractals (Second Edition), Springer
Summary: The groundbreaking documentary accompanying this book, brought the subject of fractals to the attention of the general public for the first time. Contributors to the film are joined by other leading experts in this latest edition of âThe Colours of Infinityâ, a comprehensive survey of fractal theory and practice. Incorporating an additional chapter on the money markets by Benoit Mandelbrot, the documentary has also been re-mastered providing stunning new fractal animations. A must read for anyone with an interest in the âbeauty and power of fractalsâ.
Brain-Computer Interfaces: Revolutionizing Human-Computer Interaction, Springer
Summary: A brain-computer interface (BCI) establishes a direct output channel between the human brain and external devices. BCIs infer user intent via direct measures of brain activity and thus enable communication and control without movement. This book, authored by experts in the field, provides an accessible introduction to the neurophysiological and signal-processing background required for BCI, presents state-of-the-art non-invasive and invasive approaches, gives an overview of current hardware and software solutions, and reviews the most interesting as well as new, emerging BCI applications.
Algorithmic Randomness and Complexity, Springer
Summary: Intuitively, a sequence such as 101010101010101010â¦ does not seem random, whereas 101101011101010100â¦, obtained using coin tosses, does. How can we reconcile this intuition with the fact that both are statistically equally likely? What does it mean to say that an individual mathematical object such as a real number is random, or to say that one real is more random than another? And what is the relationship between randomness and computational power? (...)
