Market Takes A Gamble On Carbon Futures, Nature
Excerpts: Business is booming on Europe's emissions market.
The global carbon market is far busier this year than last, according to figures released this month. Around 1.2 gigatonnes of carbon - worth 15.8 billion (US$21.4 billion) - were traded worldwide in the first half of 2007, primarily on the European Union (EU) Emissions Trading Scheme, according to analysts at carbon-market consultants Point Carbon in Oslo, Norway. Last year saw a mere 22.5 billion change hands all year. But another Point Carbon analysis points out that the infant US market of ten northeastern states looks to be planning too many initial allowances.
Impact Of Fraud On The Mean-Field Dynamics Of Cooperative Social Systems, APS
Excerpts: The evolution of costly cooperation between selfish individuals seems to contradict Darwinian selection, as it reduces the fitness of a cooperating individual. However, several mechanisms such as repeated interactions or spatial structure can lead to the evolution of cooperation. One such mechanism for the evolution of cooperation, in particular among humans, is indirect reciprocity, in which individuals base their decision to cooperate on the reputation of the potential receiver, which has been established in previous interactions.
Coexistence of Social Norms based on In- and Out-group Interactions, arXiv
Excerpt: The question how social norms can emerge from microscopic interactions between individuals is a key problem in social sciences to explain collective behavior. In this paper we propose an agent-based model to show that randomly distributed social behavior by way of local interaction converges to a state with a multimodal distribution of behavior. This can be interpreted as a coexistence of different social norms, a result that goes beyond previous investigations.
Dynamics of Opinions and Social Structures, arXiv
Excerpt: Social groups with widely different music tastes, political convictions, and religious beliefs emerge and disappear on scales from extreme subcultures to mainstream mass-cultures. Both the underlying social structure and the formation of opinions are dynamic and changes in one affect the other. Several positive feedback mechanisms have been proposed to drive the diversity in social and economic systems, but little effort has been devoted to pinpoint the interplay between a dynamically changing social network and the spread and gathering of information on the network.
Writing With Pictures: Toward A Unifying Theory Of Consumer Response To Images, Innovations-report
Excerpts: A new paper (...) argues that images in contemporary consumer culture are an emergent form of writing. (...) their premise is that mass communications technology has created a "cultural classroom" in which the world's first democratic pictography has developed. They support this argument with a series of experiments that demonstrate contemporary consumers' ability to read pictures - even abstract images - as statements of product features. "The idea that pictures in commercial communication operate as writing is consistent with the world record, no matter how counterintuitive the notion may first seem," write (...).
Sales Prices: How Right Digits Affect Perception of Discounts, ScienceDaily
Excerpts: The amount of the discount may be less important than the numerical value of the farthest right digit, explains a new study (...) identify a visual distortion effect that may influence how consumers look at sale prices. The researchers show that "right-digit effect" influences consumer perception of sale prices. When the right digits are small, people perceive the discount to be larger than when the right digits are large. In other words, an item on sale for $211 from the original price of $222 is thought to be a better deal than an item on sale for $188 from an original price of $199, (...).
Early Urban Development in the Near East, Science
Excerpts: It has been thought that the first cities in the Near East were spatially extensive and grew outward from a core nucleated village while maintaining a more or less constant density in terms of persons or households per unit of area. The general applicability outside of the Near East of this southern Mesopotamian.derived model has been questioned recently, and variations from it are increasingly recognized. We can now demonstrate that such variation was present at the beginnings of urbanism in the Near East as well.
Archaeology: Murder in Mesopotamia?, Science
Excerpts: A close examination of the surrounding area reveals settlement in the period of 4200 to 3900 B.C.E. extending over an astonishing 55 hectares, an order of magnitude larger than other settlements of the time. During the first half of the 4th millennium B.C.E., Brak had more than doubled in size and its population density also increased. Only one city in southern Mesopotamia--Uruk--was likely larger in this era. And unlike Uruk, which was densely populated primarily in the center, early Brak appears to have featured various clusters of neighborhoods separated by open space.
Whose Business Is The Business Climate?, Bangor Daily News
Excerpts: In the quarter century since Ronald Reagan crushed the air traffic controllers' strike, and precipitated a dramatic decline in private sector unionization, economic inequality has grown. Productivity increases, strangely enough, have lagged behind those of the 1945-1975 period. Economists have no conclusive explanation for this, but it is worth noting, as Sam Bowles, director of the Behavioral Sciences Program at the Santa Fe Institute has pointed out, that with growing inequality in America has come a spiraling need for guard labor.
Researchers Find "Tall" Gene, dBTechno News
Excerpts: A team of scientists from Britain and the U.S. are on a high today as they have identified the first gene directly linked to a persons height, according to media reports Monday.
Examining DNA from 35,000 people, the researchers found that just one single letter in the human genetic code is likely responsible for making someone short, or tall, researchers said.
Scientists believe that inheriting a form of the gene HMGA2 that also carries the letter C in the genetic code instead of T will add a quarter of an inch in height. Two copies of the gene can result in a height increase of 2 inches.
Scientists Discover Height Gene, BBC News
Excerpts: Taller people are statistically more likely to be at risk from prostate, bladder and lung cancer.
This suggests that the genes that regulate cell growth and division may also play a role in the uncontrolled cell proliferation characteristic of cancer. (...)
"Because height is a complex trait, involving a variety of genetic and non-genetic factors, it can teach us valuable lessons about the genetic framework of other complex traits, such as diabetes, cancer and other common human diseases."
Ethiopian Plateau Formation Coincided With Climate Change That May Have Spurred Human Evolution, ScienceDaily
Excerpt: More than three million years ago, early hominins evolved the ability to walk upright and in doing so started us along the evolutionary path that eventually gave rise to Homo sapiens. It was Darwin who first suggested that a change of climate, giving rise to vast, arid, savannahs, may have spurred on human evolution all those millions of years ago. But what caused that change of climate? Could the formation of one of Earth's most spectacular landscapes, the Ethiopian Plateau, have been responsible for development of the great African grasslands? And if so, what were the geological processes (...).
Towards a Physics of Evolution: Critical Diversity Dynamics at the Edges of Collapse and Bursts of Diversification
Excerpt: Systems governed the standard mechanisms of biological or technological evolution are often described by catalytic evolution equations. We study the structure of these equations and find an analogy with classical thermodynamic systems. In particular we can demonstrate the existence of several distinct phases of evolutionary dynamics: a phase of fast growing diversity, one of stationary, finite diversity, and one of rapidly decaying diversity. While the first two phases have been subject to previous work, here we focus on the destructive aspects Ð in particular the phase diagram Ð of evolutionary dynamics. The main message is that within a critical region massive loss of diversity can be triggered by very small external fluctuations.
Mobility Promotes And Jeopardizes Biodiversity In Rock-Paper-Scissors Games, Nature
Excerpts: Biodiversity is essential to the viability of ecological systems. Species diversity in ecosystems is promoted by cyclic, non-hierarchical interactions among competing populations. Central features of such non-transitive relations are represented by the 'rock-paper-scissors' game, (...). In combination with spatial dispersal of static populations, this type of competition results in the stable coexistence of all species and the long-term maintenance of biodiversity. However, population mobility is a central feature of real ecosystems: animals migrate, bacteria run and tumble. Here, we observe a critical influence of mobility on species diversity.
Urban Birds Have Broader Environmental Tolerance, Biol. Lett.
Excerpt: Urbanization dramatically changes the composition and diversity of biotic communities. The characteristics distinguishing species that persist in urban environments, however, are poorly understood. Here we test the hypothesis that broadly adapted organisms are better able to tolerate urbanization, using a phylogenetically controlled, global comparison of birds. We compared elevational and latitudinal distributions of 217 urban birds found in 73 of the world's largest cities with distributions of 247 rural congeners to test the hypothesis that urban birds possess broader environmental tolerance. Urban birds had markedly broader environmental tolerance than rural congeners, (...).
The Emergence Of A Sense Of Orientation, ScienceDaily
Excerpts: To orient ourselves, we mainly need two pieces of information: where am I and in which direction am I heading? Experiments in the rat have shown that these types of information are directly accessible and independently coded in the brain. When the rat explores a new territory, so-called place cells and head direction cells form within only a few minutes. Place cells are active when the rat visits a particular area, no matter which direction it is facing. In contrast, head direction cells code the direction the rat is heading, (...). Also humans presumably have these and other types of cells (...).
Molecular Biology: Damage Control, Nature
Excerpts: The chemical composition of normal DNA at the end of chromosomes does not differ from that of damaged and broken DNA within chromosomes. New findings hint at how the DNA-repair machinery distinguishes the two.
The maintenance of genome integrity is crucial for the survival of every organism. So even a single break along a chromosome triggers a molecular signalling cascade that leads to an appropriate DNA-damage response (DDR). This response allows recognition of the damage site and decelerates cell-cycle progression, giving the cell a chance to repair the damage.
Organic Chemistry: Synthesis Mimics Natural Craftsmanship, Science
Excerpts: When it comes to making complex molecules, microbes are nature's master craftsmen. (...)
Take a class of long, ladderlike toxins, such as those made by marine microbes called dinoflagellates that are responsible for fish-killing "red tides." (...) create the compounds by launching a cascade of reactions that break apart a series of small molecular rings as the first step to adding successive rungs to the ladder. The trouble is that synthetic chemists have never managed to create these cascades in water, leaving them to wonder whether it's truly the way the dinoflagellates do it.
Epoxide-Opening Cascades Promoted by Water, Science
Excerpts: Selectivity rules in organic chemistry have been inferred largely from nonaqueous environments. In contrast, enzymes operate in water, and the chemical effect of the medium change remains only partially understood. Structural characterization of the "ladder" polyether marine natural products raised a puzzle that persisted for 20 years: Although the stereochemistry of adjacent tetrahydropyran (THP) cycles would seem to arise from a biosynthetic cascade of epoxide-opening reactions, experience in organic solvents argued consistently that such a pathway would be kinetically disfavored.
Excerpts: This onslaught of "living pollution" has been particularly apparent and - in the case of viral hemorrhagic septicemia - gruesome this year. But it's not new. For decades, the people living along our coastlines have struggled to eradicate or contain foreign plants, animals and microorganisms that enter the United States by the billions each year via international shipping vessels.
The annual cost to the United States of attempting to control aquatic invaders is about $9 billion. That number will continue to rise, as will the rate of new invasive species, unless federal, state and local governments work together to regulate their primary source: ballast water(...)

Ecology: Doing Battle With the Green Monster of Taihu Lake, Science
Excerpts: With global temperatures rising, warmer surface water leads to less mixing, which favors the growth of toxic cyanobacteria. Deciphering the toxins' biological role and how the environment influences their production may suggest strategies for making blooms less venomous, (...).
Cyanobacteria have a long history of acquiring remarkable adaptations, such as nitrogen fixation and gas vesicles that keep them afloat and enable them to outcompete diatoms and green algae for light and nutrients.
Chaotic Oscillations And Cycles In Multi-Trophic Ecological Systems, J. Theor. Biol.
Excerpt: A set of multi-trophic population models are described, all of which yield an interesting form of chaotic dynamics-namely, the populations cycle in a periodic fashion, yet the peak abundance within each cycle is erratic and irregular over time. Since there are many ecological and biological systems that are characterized with this same form of "uniform phase-growth and chaotic amplitude (UPCA)," these models should be useful in a range of applications. We discuss their relevance to the well-known Canadian hare-lynx system, and other small mammal foodwebs which together comprise wildlife's unusual "four and ten year cycle." (...)
Book report on: Why Beauty is Truth, Ian Stewart, 2007 Basic Books
Symmetry is central to modern physics. Source: Bahman Kalantari/Science Photo Library
Albert Einstein was the first physicist to think in the modern style of symmetry, and Stewart covers the development and implications of special and general relativity through their underlying symmetry principles. Today, group theory underlies the Standard Model of particle physics through the concept of local gauge invariance. However, the book underplays the famous theorem of the German mathematician Emmy Noether that connects symmetry to conservation laws, and which Einstein and David Hilbert so championed.
Abstract: We show how theory building can naturally distinguish between regularity and randomness. Starting from basic modeling principles, using rate distortion theory and computational mechanics we argue for a general information-theoretic objective function that embodies a trade-off between a model's complexity and its predictive power. The family of solutions derived from this principle corresponds to a hierarchy of models. At each level of complexity, they achieve maximal predictive power, identifying a process's exact causal organization in the limit of optimal prediction. Examples show how theory building can profit from analyzing a process's causal compressibility, which is reflected in the optimal models' rate-distortion curve.

Theoretical Physics: A Black Hole Full Of Answers, Nature
Excerpts: A facet of string theory, the currently favoured route to a 'theory of everything', might help to explain some properties of exotic matter phases - such as some peculiarities of high-temperature superconductors.
How are heat and charge transported within a high-temperature superconductor? And what happens when heavy nuclei are torn apart to make the soup of elementary particles known as a quark-gluon plasma?
In its near 40-year history, string theory has gone from a theory of hadrons to a theory of everything to, possibly, a theory of nothing. Indeed, modern string theory is not even a theory of strings but one of higher-dimensional objects called branes. Matthew Chalmers attempts to disentangle the immense theoretical framework that is string theory, and reveals a world of mind-bending ideas, tangible successes and daunting challenges - most of which, perhaps surprisingly, are rooted in experimental data.
Physics In The Cell: Spring Theory, Nature
Excerpts: Spring theory, as he calls it, might help explain a phenomenon he is deeply interested in - how the tiny biochemical machinery of the cell can manage billions of bits of information stored on vast polymer strings that need to be read, copied and packaged into an incredibly small space.
In the cartoon models that illustrate textbooks on cell- and molecular biology, purposeful proteins orchestrate neat, stepwise molecular dances as they react to coloured blobs and bind a perfect DNA staircase.
Diamond Stabilization Of Ice Multilayers At Human Body Temperature, APS
Excerpts: Diamond is a promising material for wear-resistant medical coatings. Here we report a remarkable increase in the melting point of ice resting on a diamond (111) surface modified with a submonolayer of Na+. Our molecular dynamics simulations show that the interfacial ice bilayer melts at a temperature 130 K higher than in free ice, and relatively thick ice films (2.6 nm at 298 K and 2.2 nm at 310 K) are stabilized by dipole interactions with the substrate. This unique physical effect may enable biocompatibility-enhancing ice overcoatings for diamond at human body temperature.
Warm Ice Could Improve Medical Implants, PhysicsWorld.com
Excerpts: Simulations suggest ice forms on modified diamond at body temperature
Warm ice could improve medical implants
Ice melts at 0 oC, right? Not necessarily, according to Alexander Wissner-Gross and Efthimios Kaxiras at Harvard University in the US. The pair used computer simulations to show that diamond surfaces implanted with sodium atoms can sustain very thin layers of ice at temperatures up to 37 oC. The frosty covering could help to make artificial medical implants more compatible inside the human body, say the researchers
A subject using Tan's system spends 10 to 20 minutes performing a series of tasks that require either high or low concentration--such as remembering letters or images for various amounts of time. EEG readings taken during the activity are fed to a computer, which manipulates them mathematically to generate thousands of derivations called "features." The machine- learning algorithm then sifts through the features, identifying patterns that reliably indicate the subject's concentration level when the data was collected.

Software Via The Internet: Microsoft In 'Cloud' Computing, NY Times
This week, it [Microsoft, Ed.] plans to turn that strategy upside down, making available free software that connects its Windows operating system to software services delivered on the Internet, a practice increasingly referred to as "cloud" computing. The initiative is part of an effort to connect Windows more seamlessly to a growing array of Internet services.
James C. Best Jr.
The strategy is a major departure for Microsoft, which primarily sells packaged software for personal computers. With this new approach, Microsoft hopes to shield its hundreds of millions of software customers from competitors like Google and Salesforce.com, which already offer software applications through the Internet.
I.B.M. Researchers Advancing Computer Processing Ability, NY Times
Researchers at I.B.M. laboratories say they have made progress toward storing information and computing at the level of individual atoms.
An illustration of I.B.M.'s technique for storing data on a single atom. An iron atom on a copper surface could store a single bit of binary data, with "0" or "1" indicated by the orientation of the atom's magnetic field.
The scientists documented their work in two papers appearing on Friday in the journal Science. Both papers are focused on new understanding of the behavior of magnetism at the tiny scale of nanotechnology, where scientists hope to develop electronics made from components that are far smaller than today's transistors and wires.
IBM Measures Single-Atom Memory, Molecular Switch, EE Times
Even the highest density hard-disk drives use approximately 1 million magnetic atoms to store a single bit of information. IBM's Almaden Research Center (San Jose, Calif.) has measured the ability to store a bit on a single atom, portending hard drives with ultra-high storage capacity.

Complex Challenges: Global Terrorist Networks
Global Warning: Terror's Changing Face, The Age
Excerpts: "The key terrorist threat today is that al-Qaeda has regrouped and reorganised from the setbacks we inflicted on it immediately after 9/11 and Afghanistan and is once again capable of carrying out terrorist attacks on a global canvas," he told The Age.
"We shifted our focus from the struggle against al-Qaeda in South Asia to invading Iraq in 2003 and subsequently became pre-occupied, first with the escalating insurgency and then as the country became submerged in civil war.
Excerpt: A cornerstone of US intelligence reform is 'information sharing' as a means of adapting to contemporary security challenges. It was a central recommendation of the 9/11 Commission, reflected in the wide-ranging 'Information Sharing Environment' mandated by the Intelligence Reform and Terrorism Prevention Act of 2004. Yet the underlying logic of information sharing for intelligence reform has received little attention. Drawing on information and communications theory, this paper critiques the logic by highlighting problems of sense-making and interpretation overlooked amid the scholarly enthusiasm for an intelligence 'culture of sharing'.

Center First Gives Way to Center Last - Have you noticed the change in the Iraq debate?, NY Times
Excerpts: As Iraqi national politics stagnated, the tribes began to take the initiative. The process started in Anbar Province, when the local tribes revolted against Al Qaeda. It has continued in Diyala Province and even in Baghdad neighborhoods like Ameriya. In the South, moderate Shiite parties have begun to resist the Sadrists, while in many places local groups that look like mafia families struggle to impose order on their turf.
In other words, organic local actors - some thuggish, some not - have begun to impose a security structure on parts of the country.
