Behind Insurer's Crisis, Blind Eye to a Web of Risk, NY Times
Excerpts: (...) insights into the mystifying, virally connected - and astonishingly fragile - financial world that began to implode in recent weeks.(...) the system was vulnerable because of intricate financial contracts known as credit derivatives, which insure debt holders against default. They are fashioned privately and beyond the ken of regulators - sometimes even beyond the understanding of executives peddling them.
Originally intended to diminish risk and spread prosperity, these inventions instead magnified the impact of bad mortgages like the ones that felled Bear Stearns and Lehman and now threaten the entire economy.

Economics: Can Neural Data Improve Economics?, Science
Excerpts: Summary: Researchers are exploring how neurobiology can guide economic experiments and refine economic models. (...)Neuroeconomists Camerer et al. recently predicted that "We will eventually be able to replace the simple mathematical ideas that have been used in economics with more neurally-detailed descriptions" (2). By contrast, economic theorists Gul and Pesendorfer maintain that neuroscience evidence is irrelevant to economics because "the latter makes no assumptions and draws no conclusions about the physiology of the brain" (3). Limited to current practice in economics, the Gul-Pesendorfer assertion is correct. In a standard economic model, a decision-maker is confronted with several options, and the purpose of the exercise is to predict which one the subject will select.

Understanding Overbidding: Using the Neural Circuitry of Reward to Design Economic Auctions, Science
Excerpts: We take advantage of our knowledge of the neural circuitry of reward to investigate a puzzling economic phenomenon: Why do people overbid in auctions? Using functional magnetic resonance imaging (fMRI), we observed that the social competition inherent in an auction results in a more pronounced blood oxygen level-dependent (BOLD) response to loss in the striatum, with greater overbidding correlated with the magnitude of this response. Leveraging these neuroimaging results, we design a behavioral experiment that demonstrates that framing an experimental auction to emphasize loss increases overbidding.- Source: Understanding Overbidding: Using the Neural Circuitry of Reward to Design Economic Auctions

Emergent Community Structure In Social Tagging Systems, Adv. Complex Sys.
Excerpt: A distributed classification paradigm known as collaborative tagging has been widely adopted in new Web applications designed to manage and share online resources. Users of these applications organize resources (Web pages, digital photographs, academic papers) by associating with them freely chosen text labels, or tags. Here we leverage the social aspects of collaborative tagging and introduce a notion of resource distance based on the collective tagging activity of users. We collect data from a popular system and perform experiments showing that our definition of distance can be used to build a weighted network of resources with a detectable community structure.

A Cat's Cradle For Policy, Nature
Excerpts: The OECD is developing a strategy for nations to measure and ultimately promote innovation. (...) Developing such a strategy poses a significant challenge because of the complex nature of innovation. Innovation is the creation of something new - a good or a service, a way to deliver goods or services, an organizational or management structure - or the capturing of new markets. Knowledge is an important ingredient of innovation. (...) However, in a world of modularity and flexible platforms for technologies and practices, users are more able to improve and augment their systems, creating a web of knowledge that can change the behaviour of other users or of suppliers. This is a complex process, a system of innovation.

Learning From Mistakes Only Works After Age 12, Study Suggests, ScienceDaily
Excerpts: Eight-year-old children have a radically different learning strategy from twelve-year-olds and adults. Eight-year-olds learn primarily from positive feedback ('Well done!'), whereas negative feedback ('Got it wrong this time') scarcely causes any alarm bells to ring. Twelve-year-olds are better able to process negative feedback, and use it to learn from their mistakes. Adults do the same, but more efficiently. The switch in learning strategy has been demonstrated in behavioural research, which shows that eight-year-olds respond disproportionately inaccurately to negative feedback. But the switch can also be seen in the brain, as developmental psychologist (...) discovered using fMRI research. (...)- Source: Learning From Mistakes Only Works After Age 12, Study Suggests

Multiple Conflict-Driven Control Mechanisms In The Human Brain, Trends Cogn. Sc.
Excerpt: Conflict between competing neural representations is thought to serve as an internal signal for the recruitment of ‘cognitive control', which resolves conflict by biasing information processing in line with current task demands. Because conflict can occur at different levels of stimulus and response representations, several recent investigations have examined whether conflict-driven cognitive control is domain-general or domain-specific, that is, whether control recruited by one type of conflict affects the resolution of another, but these studies have produced contrary conclusions. I argue here that a critical reading of this literature indicates that the effects of conflict-driven control are domain-specific (...).- Source: Multiple Conflict-Driven Control Mechanisms In The Human Brain

Is Sleep Essential?, PLoS Biol
Excerpt: Everybody knows that sleep is important, yet the function of sleep seems like the mythological phoenix (...) But what if the search for an essential function of sleep is misguided? What if sleep is not required but rather a kind of extreme indolence that animals indulge in when they have no more pressing needs, such as eating or reproducing? In many circumstances sleeping may be a less dangerous choice than roaming around, wasting energy and exposing oneself to predators. (...) This "null hypothesis" would explain why nobody has yet identified a core function of sleep. But how strong is the evidence supporting it? And are there counterexamples?- Source: Is Sleep Essential?

Social Science: Unlocking The Potential Of The Spoken Word, Science
Excerpts: Advances in speech processing may soon place speech and writing on a more equal footing, with broad implications for many aspects of society. (...) The wide diffusion of writing required standardization to facilitate mutual intelligibility. Will increasingly broad dissemination of spoken language accelerate the demise of regional dialects and less widely spoken languages? Written contracts today have greater legal standing than verbal ones. Will that distinction persist in a world in which spoken and written words have equal permanence? How can we harness this new technology to accelerate access to new knowledge, and what would be the implications of the resulting compression of innovation cycles?

The Coevolution of Cultural Groups and Ingroup Favoritism, Science
Excerpts: Cultural boundaries have often been the basis for discrimination, nationalism, religious wars, and genocide. Little is known, however, about how cultural groups form or the evolutionary forces behind group affiliation and ingroup favoritism. Hence, we examine these forces experimentally and show that arbitrary symbolic markers, though initially meaningless, evolve to play a key role in cultural group formation and ingroup favoritism because they enable a population of heterogeneous individuals to solve important coordination problems.- Source: The Coevolution of Cultural Groups and Ingroup Favoritism

Animal Behaviour: Counting Bee, Nature
Excerpts: Honeybees (Apis mellifera) can count up to four - (...) fly down a tunnel in search of food placed beside one of five identical landmarks positioned at intervals. (...) Moving the landmarks nearer to or farther away from each other did not fool the bees, showing that they were not relying on distance, but were counting the number of landmarks before the food. Changing landmarks from stripes to spots had no effect either, suggesting that bees can use numbers in an abstract way.

Predation Increases Acoustic Complexity In Primate Alarm Calls, Biol. Lett.
Excerpts: According to most accounts, alarm calling in non-human primates is a biologically hardwired behaviour with signallers having little control over the acoustic structure of their calls. In this study, we compared the alarm calling behaviour of two adjacent populations of Diana monkeys (...) which differ significantly in predation pressure. At Taï, monkeys regularly interact with two major predators, crowned eagles and leopards, while at Tiwai, monkeys are only hunted by crowned eagles. We monitored the alarm call responses of adult male Diana monkeys to acoustic predator models.

Sex is Always Well Worth Its Two-fold Cost, arXiv
Excerpt: Sex is considered as an evolutionary paradox, since its evolutionary advantage does not necessarily overcome the two fold cost of sharing half of one's offspring's genome with another member of the population. Here we demonstrate that sexual reproduction can be evolutionary stable even when its Darwinian fitness is twice as low when compared to the fitness of asexual mutants. We also show that more than two sexes are always evolutionary unstable.- Source: Sex is Always Well Worth Its Two-fold Cost

Neuroscience: An Ageing View Of Myelin Repair, Nature
Excerpts: When the myelin layer that covers neuronal processes is lost through disease, neural stem cells recapitulate the developmental program of 'myelination'. The underlying molecular mechanisms often fail in the ageing brain. (...)Therefore, impaired remyelination was associated with an age-dependent loss of 'epigenetic memory'. (...)
A closer look revealed that the impaired remyelination in older mice did not result from various possible effects - an altered inflammatory response, for example, (...). Rather, genes encoding inhibitory transcription factors (...) and factors that promote stem-cell activity (...) were transcribed for much longer than normally seen in remyelination.

Although almost half of the supers had osteoporosis and almost 90% had cataracts, 41% of them either lived on their own or required only minimal help with tasks such as preparing food, dressing, and bathing. Cardiovascular disease, the leading killer in developed countries, was rare among supercentenarians--only 6% had suffered heart attacks and 13% reported strokes. Diabetes and Parkinson's disease were also uncommon in the group, striking only 3% of the subjects each. Like centenarians, supercentenarians seem to be good at putting off the day when they become disabled, says Perls.

Growing Up Too Fast May Mean Dying Young In Honey Bees, ScienceDaily
Excerpts: (...) transitions to aerobically-expensive behaviors in organisms living free in nature can have important consequences affecting the pace of aging. Reactive oxygen species (ROS) occur as a by-product of aerobic metabolism and impair cellular function by damaging proteins, nucleotides and lipids. Organisms possess a variety of anti-oxidant mechanisms to mitigate the effects of ROS, and the oxidative stress model of aging and senescence suggests that physiological performance declines with age due to lifetime accrual of ROS-induced damage and progressively limited anti-oxidant capacity. Hence, the onset, pace and duration of energetically-intense behaviors should affect lifetime kinetics of ROS-induced damage, anti-oxidant responses, physiological capacity and longevity.

Cancer: Entangled Pathways, Nature
Excerpts: A medley of molecules, and the interactions between them, mediate cancer. The latest news is that the enzyme CDK8 orchestrates cross-talk between two signalling pathways that are frequently deregulated in human cancers. There is no simple answer to the question of which cellular proteins or signalling pathways are responsible for making a cell cancerous. (...) Mutations in the gene for the retinoblastoma tumour-suppressor protein, which is part of another signalling pathway, are also frequently associated with cancer. When put together, the findings of Firestein et al. and Morris et al., presented in this issue, lead to the identification of a point at which these important pathways could communicate with each other in colorectal cancer.

Cancer: The Metastasis Cascade, Science
Excerpts: The view of evolution of tumor cells toward metastasis takes a new twist. (...)The late metastasis model places selection of genetic and epigenetic alterations mostly inside the primary tumor. If so, late-disseminating cells are genetically similar to the primary tumor, which can be used as a surrogate marker to choose a drug against disseminated tumor cells. (Bottom) By contrast, early-disseminated tumor cells accumulate such alterations at distant sites and diverge genetically from the primary tumors. Consequently, they may respond differently to drugs that are administered systemically.

Intraseasonal Interaction Between The Madden-Julian Oscillation And The North Atlantic Oscillation, Nature
Excerpts: Bridging the traditional gap between the spatio-temporal scales of weather and climate is a significant challenge facing the atmospheric community. In particular, progress in both medium-range and seasonal-to-interannual climate prediction relies on our understanding of recurrent weather patterns and the identification of specific causes responsible for their favoured occurrence, persistence or transition.

Excerpts: Summary: Although solvent molecules move about randomly in a liquid, an experiment showed that changing their initial arrangement affected the rate of a chemical process. (...) What these special instances of nonlinear energy transfer do promise, however, are some long-sought experimental entries into the microscopic origins of friction. The slowing down of mechanical motion by friction is nothing but the effectively irreversible transfer of molecular kinetic energy into a sea of countless other molecular degrees of freedom. The second law of thermodynamics guarantees that such transfers occur, but it cannot explain how or when they happen, or reveal the specific molecular motions involved.

A short notice from Dean LeBaron
Dear ComDig Readers,
Our editor, Dr. Gottfried Mayer, is affectionately esteemed by many of you -- as readers, you know he devotes himself unselfishly to widening our knowledge of complexity science. He was recently diagnosed with advanced colon cancer and given a timetable of a very few years. Knowing Gottfried, you can imagine that, in addition to the customary processes of chemotherapy, he would explore other frontier therapies, especially those arising out of interdisciplinary applications of complexity. These are expensive ... if he can find them.
Many of you have sent your good wishes and indicated your desire to assist. With Gottfried's permission, I am posting this note with information, below, about how to send contributions to him. Please indicate the source since Gottfried will want to express his warm gratitude.
I know that Gottfried, the good scientist that he is, will explain from time to time what he is doing and what the results are ... and we will follow his progress with great interest and hope.
Dean LeBaron
