James Clerk Maxwell, Nature
Summary: 150 years ago this month a young James Clerk Maxwell wrote down the equations that, by bringing together the physics of electricity and magnetism, laid the foundations for modern physics. Four pieces in this week's Nature explore how Maxwell's insight emerged from grappling with the problems of telegraphy and discuss its legacies, from telecommunications and microelectronics to metamaterials and unification.
Unification + 150, Nature
Excerpt: The Higgs discovery could take that unification a giant step further by filling in the last and most critical piece of the 'standard model', an extension of Maxwell's equations that encompasses three of the four forces of nature: electromagnetism and the weak and strong forces that act on subatomic particles. The Higgs boson is thought to interact with electrons, quarks and other fundamental particles, endowing them with mass â€" and thus making it possible for the standard model to describe the Universe as we know it.

Networks in biology: Handling biological complexity requires novel inputs into network theory, Complexity
Excerpt: The year 2009 was the tenth anniversary of the first publication on scale-free networks and the fiftieth anniversary of the invention of random graphs. (...) Understanding and modeling complex systems without consideration of network topology and network evolution became out-of-date and practically impossible. The ErdĂ¶s-RĂ©nyi model initiated a real break-through in the sense that statistical properties of graphs and networks became accessible without knowledge of the connection details. (...)
Biology, Methodology or Chance? The Degree Distributions of Bipartite Ecological Networks, PLoS ONE
Excerpt: The shape of a degree distribution, for example whether it follows an exponential or power-law form, is typically taken to be indicative of the processes structuring the network. The skewed degree distributions of bipartite mutualistic and antagonistic networks are usually assumed to show that ecological or co-evolutionary processes constrain the relative numbers of specialists and generalists in the network. I show that a simple null model based on the principle of maximum entropy cannot be rejected as a model for the degree distributions in most of the 115 bipartite ecological networks tested here.
Developmental motifs reveal complex structure in cell lineages, Complexity
Abstract: Many natural and technological systems are complex, with organizational structures that exhibit characteristic patterns but defy concise description. One effective approach to analyzing such systems is in terms of repeated topological motifs. Here, we extend the motif concept to characterize the dynamic behavior of complex systems by introducing developmental motifs, which capture patterns of system growth. As a proof of concept, we use developmental motifs to analyze the developmental cell lineage of the nematode Caenorhabditis elegans, revealing a new perspective on its complex structure. We use a family of computational models to explore how biases arising from the dynamics of the developmental gene network, as well as spatial and temporal constraints acting on development, contribute to this complex organization.
Hans Rosling and the magic washing machine, TED.com
About this talk: What was the greatest invention of the industrial revolution? Hans Rosling makes the case for the washing machine. With newly designed graphics from Gapmider, Rosling shows us the magic that pops up when economic growth and electricity turn a boring wash day into an intellectual day of reading.

David Brooks: The social animal, TED.com
About this talk: Tapping into the findings of his latest book, NYTimes columnist David Brooks unpacks new insights into human nature from the cognitive sciences -- insights with massive implications for economics and politics as well as our own self-knowledge. In a talk full of humor, he shows how you can't hope to understand humans as separate individuals making choices based on their conscious awareness.
Janna Levin: The sound the universe makes, TED.com
About this talk: We think of space as a silent place. But physicist Janna Levin says the universe has a soundtrack -- a sonic composition that records some of the most dramatic events in outer space. (Black holes, for instance, bang on spacetime like a drum.) An accessible and mind-expanding soundwalk through the universe.
Rob Harmon: How the market can keep streams flowing, TED.com
About this talk: With streams and rivers drying up because of over-usage, Rob Harmon has implemented an ingenious market mechanism to bring back the water. Farmers and beer companies find their fates intertwined in the intriguing century-old tale of Prickly Pear Creek.
Happiness is assortative in online social networks, arXiv
Excerpt: Social networks tend to disproportionally favor connections between individuals with either similar or dissimilar characteristics. This propensity, referred to as assortative mixing or homophily, is expressed as the correlation between attribute values of nearest neighbour vertices in a graph. Recent results indicate that beyond demographic features such as age, sex and race, even psychological states such as "loneliness" can be assortative in a social network. In spite of the increasing societal importance of online social networks it is unknown whether assortative mixing of psychological states takes place in situations where social ties are mediated solely by online networking services in the absence of physical contact. Here, we show that general happiness or Subjective Well-Being (SWB) of Twitter users, as measured from a 6 month record of their individual tweets, is indeed assortative across the Twitter social network. (...)
Possible Early Warning Sign for Market Crashes, Wired
Excerpt: Complexity researchers who study the behavior of stock markets may have identified a signal that precedes crashes.
They say the telltale sign is a measure of co-movement, or the likelihood of stocks to move in the same direction. When a market is healthy, co-movement is low. But in the months and years before a crash, co-movement seems to grow.
Regardless of whether stock prices go up or down or stay the same, they do so in tandem. People are copying each other, and a small nudge can send everyone in the same direction. The system appears primed for collapse.
Devastating Earthquake Defied Expectations, Science
Excerpt: The earthquake's astonishing power and unexpected location also expose the futility of forecasting where and when the next Big One will hit, says Robert Geller, a geophysicist at the University of Tokyo. Even in a country as extensively instrumented and thoroughly studied as Japan, he says, major quakes always â€śseem to be ones not expected.â€ť
Editor's Note: The sad case of the Japan earthquake and tsunami shows again the inherent limits of predictability due to complexity and the need of adaptation to complement prediction.
Cooperation in bike racingâ€"When to work together and when to go it alone, Complexity
Abstract: We present an agent-based model of bicycle racing that incorporates both physiology and the types of multiplayer scenarios that arise in real races. In these scenarios, riders can choose to share the workload with other riders (cooperate) or pursue their own self-interests (defect). We compare the model's predictions to race situations and use it to investigate how different strategies can affect outcomes. We find that an individual player's best strategy depends on fitness level: below-average riders fare better as defectors whereas above-average riders perform better as cooperators. The strategies of stronger riders affect their teammates' results as well. The teammates of defecting strong riders fare worse overall than the teammates of cooperating strong riders. These results reproduce a dynamic that played out in the 2009 Tour de France. The winner, Alberto Contador, pursued a strategy perceived by many to be unusually uncooperative by repeatedly defecting on his teammates. The strategy worked to his advantage but may have negatively affected his teammates' placements.
Extremely rare interbreeding events can explain Neandertal DNA in modern humans, arXiv
Excerpt: Considering the recent experimental discovery of Green et al that present day non-Africans have 1 to 4% of their nuclear DNA of Neandertal origin, we propose here a model which is able to quantify the interbreeding events between the two subpopulations. (...) Our results indicate that the amount of Neandertal DNA in non-Africans can be explained with maximum probability by the exchange of a single pair of individuals between the subpopulations at each 77 generations, but larger exchange frequencies are also allowed with sizable probability.
The aggregate complexity of decisions in the game of Go, Eur. Phys. J. B
Abstract: Artificial intelligence (AI) research is fast approaching, or perhaps has already reached, a bottleneck whereby further advancement towards practical human-like reasoning in complex tasks needs further quantified input from large studies of human decision-making. Previous studies in psychology, for example, often rely on relatively small cohorts and very specific tasks. These studies have strongly influenced some of the core notions in AI research such as the reinforcement learning and the exploration versus exploitation paradigms. With the goal of contributing to this direction in AI developments we present our findings on the evolution towards world-class decision-making across large cohorts of subjects in the formidable game of Go. Some of these findings directly support previous work on how experts develop their skills but we also report on several previously unknown aspects of the development of expertise that suggests new avenues for AI research to explore. In particular, at the level of play that has so far eluded current AI systems for Go, we are able to quantify the lack of `predictability' of experts and how this changes with their level of skill.
Excerpt: The field of microbial cooperation has grown enormously over the last decade, leading to improved experimental techniques and a growing awareness of collective behavior in microbes. Unfortunately, many of our theoretical tools and concepts for understanding cooperation fail to take into account the peculiarities of the microbial world, namely strong selection strengths, unique population structure, and non-linear dynamics.
Abstract: We study evolutionary games in which the rest points of the evolutionary dynamic cluster in connected components, focusing on what we call the Resource Game as a canonical example. The long-term outcome in such games can depend critically on second-order forces that were excluded from the evolutionary dynamics because they are typically insignificant compared with selection pressures. We show that the influence of second-order forces on long-term outcomes can depend on whether the reproduction underlying the evolutionary dynamics is sexual or asexual. An implication is that care is needed in adopting the convenience of an asexual model when examining the behavior of a sexual population in games with nontrivial components of rest points.
Wikipedia Information Flow Analysis Reveals the Scale-Free Architecture of the Semantic Space, PLoS ONE
Excerpt: In this paper we extract the topology of the semantic space in its encyclopedic acception, measuring the semantic flow between the different entries of the largest modern encyclopedia, Wikipedia, and thus creating a directed complex network of semantic flows.
Valuing Water: How Can Businesses Manage the Coming Scarcity?, Knowledge@Wharton
Summary: Water is a paradoxical commodity: It seems free and plentiful, yet its supply is under tremendous strain. Use of fresh water has more than doubled in the past 50 years, and many fear that we are coming close to a frightening breaking point, a world where chronic water shortages for farmers, businesses and people are the norm. Some experts even see international conflict emerging over access to dwindling supplies. Recognizing these concerns, companies are undertaking major programs to realign their water use with core business and humanitarian interests. But while objectives like being "water neutral" and using "footprinting" -- tracking the use of water throughout the supply chain -- are ambitious, what is being done to achieve them? Are these goals realistic, and will they have enough impact?
Making tools isnâ€™t childâ€™s play, Cognition
Abstract: Tool making evidences intelligent, flexible thinking. In Experiment 1, we confirmed that 4- to 7-year-olds chose a hook tool to retrieve a bucket from a tube. In Experiment 2, 3- to 5-year-olds consistently failed to innovate a simple hook tool. Eight-year-olds performed at mature levels. In contrast, making a tool following demonstration was easy for even the youngest children. In Experiment 3, childrenâ€™s performance did not improve given the opportunity to manipulate the objects in a warm-up phase. Childrenâ€™s tool innovation lags substantially behind their ability to learn how to make tools by observing others.

Excerpt: We revisit the issue of the emergence of fair behavior in the framework of the spatial Ultimatum game [...] A very frequent feature is the spontaneous emergence and fixation of quasiempathetic individuals, whose offers are very close to their acceptance thresholds. We present analytical arguments that allow an understanding of our results and give insights on the manner in which local effects in evolution may lead to such non-rational or apparently maladaptive behaviors.
Experimental Philosophy and the Problem of Free Will, Science
Abstract: Many philosophical problems are rooted in everyday thought, and experimental philosophy uses social scientific techniques to study the psychological underpinnings of such problems. In the case of free will, research suggests that people in a diverse range of cultures reject determinism, but people give conflicting responses on whether determinism would undermine moral responsibility. When presented with abstract questions, people tend to maintain that determinism would undermine responsibility, but when presented with concrete cases of wrongdoing, people tend to say that determinism is consistent with moral responsibility. It remains unclear why people reject determinism and what drives peopleâ€™s conflicted attitudes about responsibility. Experimental philosophy aims to address these issues and thereby illuminate the philosophical problem of free will.
Robot ethics: Mapping the issues for a mechanized world, Artificial Intelligence
Excerpt: As with other emerging technologies, advanced robotics brings with it new ethical and policy challenges. This paper will describe the flourishing role of robots in societyâ€"from security to sexâ€"and survey the numerous ethical and social issues, which we locate in three broad categories: safety & errors, law & ethics, and social impact.
SuperCooperators: Altruism, Evolution, and Why We Need Each Other to Succeed, Free Press
Summary: Martin Nowak, one of the worldâ€™s experts on evolution and game theory, working here with bestselling science writer Roger Highfield, turns an important aspect of evolutionary theory on its head to explain why cooperation, not competition, has always been the key to the evolution of complexity. He offers a new explanation for the origin of life and a new theory for the origins of language, biologyâ€™s second greatest information revolution after the emergence of genes. SuperCooperators also brings to light his game-changing work on disease. (...)
Fields, Forces, and Flows in Biological Systems, Garland Science
Summary: Fields, Forces, and Flows in Biological Systems describes the fundamental driving forces for mass transport, electric current, and fluid flow as they apply to the biology and biophysics of molecules, cells, tissues, and organs. Basic mathematical and engineering tools are presented in the context of biology and physiology. The chapters are structured in a framework that moves across length scales from molecules to membranes to tissues. Examples throughout the text deal with applications involving specific biological tissues, cells, and macromolecules.
The Political Gene: How Darwin's Ideas Changed Politics, Macmillan
Summary: Charles Darwin not only sparked a revolution in science, but gave birth to ideas that acquired a political dimension from the outset, one with a deeply troubling and ongoing impact. Social Darwinism, eugenics, and scientific racialismâ€"whose adherents have all claimed Charles Darwin as their inspirationâ€"became associated with some of the darkest episodes in our recent past. This beautifully crafted narrative follows the thread of theory and the historical footprints left by a myriad cast of key characters to tell an often shocking and sometimes heartbreaking story. (...)
Braintrust: What Neuroscience Tells Us about Morality, Princeton University Press
Summary: What is morality? Where does it come from? And why do most of us heed its call most of the time? In Braintrust, neurophilosophy pioneer Patricia Churchland argues that morality originates in the biology of the brain. She describes the "neurobiological platform of bonding" that, modified by evolutionary pressures and cultural values, has led to human styles of moral behavior. The result is a provocative genealogy of morals that asks us to reevaluate the priority given to religion, absolute rules, and pure reason in accounting for the basis of morality. (...)
The Mystery of Metamorphosis: A Scientific Detective Story, Chelsea Green Publishing
Summary: Metamorphosis has intrigued human observers for thousands of years. While everyone knows this trick of nature transforms caterpillars into butterflies, fewer are aware that this process of transformation also occurs in many other insect species, as well as in amphibians and-in its greatest diversity-in marine creatures. Still, despite its widespread occurrence, metamorphosis has largely remained a mystery, also to the scientists who have tried to unravel just how the transformation works. In Metamorphosis, Frank Ryan delves into the mystery headfirst, showcasing surprising new ideas that are shaking established science.
Technology: The medium is the message, Nature
Excerpt: Information is the paradigm of our time. Economies that once manufactured goods now create value by processing information. Global flows of money, ideas and news determine which countries engage with global society and which are left silently on the sidelines. A skein of pervasive mobile computing keeps us connected â€" instantly, continuously, incessantly. James Gleick's latest book, The Information, examines the genesis of the information society and the roots and consequences of information theory.
Biotechnology: Making people, Nature
Excerpt: In Unnatural
, science writer Philip Ball explores the history of our fascination with â€" and fear of â€" creating artificial people, from ancient folklore to today. Tracing a clear path from medieval alchemists' homunculi to routine assisted conception is a feat. Through his impeccable research, Ball successfully argues that the tenacious myths of the past that surround the making of people or 'anthropoeia' (his coinage) affect life-science research today.
Living Inspired, Science
Excerpt: Under the provocative and intriguing title of Bulletproof Feathers, Robert Allen (an engineer at the University of Southampton) brings together highlights from recent research in the broad areas of bioinspiration and biomimicry to explain, in simple terms, how physical scientists and engineers are increasingly using the study of the natural world as a starting point. Collectively, the six image-stuffed chapters (each written by a top researcher in the field) offer nonspecialists an intriguing sampler of bioinspiration. The various topics are organized around capabilities, from looking at new material systems to challenges that span a range of animals, such as collaborative communication and the management of fluid flow and heat transfer.

A Better View of Eras of Life, Science
Many biology classrooms and lecture theaters are adorned with posters that depict the history of life on Earth as a succession of different taxonomic groups. These posters tell the standard story of the age of invertebrates giving rise to the age of fishes, which gave rise to the age of reptiles, which gave rise to the age of mammals, which culminates with us at the pinnacle. In Principles of Social Evolution
, Andrew Bourke makes an excellent case for replacing this history, which is biased toward relatively humanlike organisms, with a hierarchical approach based on how organisms come together to form higher-level collectives, tracing the steps from genes to complex societies. He has written a superb book, one that should change how we teach and think about life on our planet.
