    Excerpts: Complex engineered and biological systems share protocol-based architectures that make them robust and evolvable, but with hidden fragilities to rare perturbations.

    Chaos, fractals, random graphs and power laws inspire a popular view of complexity in which behaviours that are typically unpredictable and fragile 'emerge' from simple interconnections among like components. But applied to the study of highly evolved systems, this attractively simple view has led to widespread confusion. A different, more rewarding take on complexity focuses on organization, protocols and architecture, and includes the 'emergent' as an extreme special case within a much richer dynamical perspective.

      Excerpts:
      Ora looks the same from four different positions. Courtesy of Bathsheba Grossman
      Symmetry attracts us. Studies comparing people's reactions to different faces have shown, for example, that they find highly symmetrical faces more attractive than less symmetrical faces. The symmetry of faces is simple and bilateral, but other three-dimensional objects can be symmetric in complex ways, leading to different kinds of beauty.

      Bathsheba Grossman, a sculptor in Santa Cruz, California, mines subtle forms of symmetry for inspiration. Her results are swirling and proportional. They may be simple or complex, but they always come together into a precise, intriguingly symmetrical pattern.

  2. Multi-Agent Approach to the Self-Organization of Networks, arXiv Next Article Bookmark and Share

    Abstract: Is it possible to link a set of nodes without using preexisting positional information or any kind of long-range attraction of the nodes? Can the process of generating positional information, i.e. the detection of ``unknown'' nodes and the estabishment of chemical gradients, and the process of network formation, i.e. the establishment of links between nodes, occur in parallel, on a comparable time scale, as a process of co-evolution?
    The paper discusses a model where the generation of relevant information for establishing the links between nodes results from the interaction of many agents, i.e. subunits of the system that are capable of performing some activities. Their collective interaction is based on (indirect) communication, which also includes memory effects and the dissemination of information in the system. The relevant (``pragmatic'') information that leads to the establishment of the links then emerges from an evolutionary interplay of selection and reamplification.

    1. Trading Networks with Price-Setting Agents, SFI Working Papers Next Article Bookmark and Share

      Excerpt: In a wide range of markets, individual buyers and sellers often trade through intermediaries, who determine prices via strategic considerations. Typically, not all buyers and sellers have access to the same intermediaries, and they trade at correspondingly different prices that reflect their relative amounts of power in the market. We model this phenomenon using a game in which buyers, sellers, and traders engage in trade on a graph that represents the access each buyer and seller has to the traders. (...)

  3. Astronomers Find First Earth-Like Planet In Habitable Zone, ESO Next Article Bookmark and Share

    Excerpts:
    Artist's impression of the planetary system around the red dwarf Gliese 581. Using the instrument HARPS on the ESO 3.6-m telescope, astronomers have uncovered 3 planets, all of relative low-mass: 5, 8 and 15 Earth masses. The five Earth-mass planet (seen in foreground - Gliese 581 c) makes a full orbit around the star in 13 days, the other two in 5 (the blue, Neptunian-like planet - Gliese 581 b) and 84 days (the most remote one, Gliese 581 d). (c) ESO
    Astronomers have discovered the most Earth-like planet outside our Solar System to date, an exoplanet with a radius only 50% larger than the Earth and capable of having liquid water. Using the ESO 3.6-m telescope, a team of Swiss, French and Portuguese scientists discovered a super-Earth about 5 times the mass of the Earth that orbits a red dwarf, already known to harbour a Neptune-mass planet. The astronomers have also strong evidence for the presence of a third planet with a mass about 8 Earth masses.

  4. Quantum Physics Says Goodbye To Reality, Physics Web Next Article Bookmark and Share

    Excerpts: Some physicists are uncomfortable with the idea that all individual quantum events are innately random. This is why many have proposed more complete theories, which suggest that events are at least partially governed by extra "hidden variables". (...)

    "Our study shows that 'just' giving up the concept of locality would not be enough to obtain a more complete description of quantum mechanics," Aspelmeyer told Physics Web. "You would also have to give up certain intuitive features of realism."

    1. Quantum Mechanics: To Be Or Not To Be Local, Nature Next Article Bookmark and Share

      Excerpts: The experimental violation of mathematical relations known as Bell's inequalities sounded the death-knell of Einstein's idea of 'local realism' in quantum mechanics. But which concept, locality or realism, is the problem?

  5. Physics: Colliding Clouds May Hone Physical Constants, Science Next Article Bookmark and Share

    Excerpts: A new spin on the atomic clock could yield some of the most precise measurements to date of fundamental physical constants--potentially providing crucial experimental tests of a number of "theories of everything." Four physicists at Pennsylvania State University (Penn State) in State College have built the prototype of a "quantum scattering interferometer"--a device capable of registering differences in the mass and other properties of atoms with unheard-of sensitivity.

  6. Chimps Lead Evolutionary Race, Nature Next Article Bookmark and Share

    Excerpts:
    R. E. KLEIN/AP
    Chimpanzees have at least 233 genes thought to be shaped by selection for beneficial mutations.
    More chimpanzee genes have been positively selected for than human ones.

    Humans are generally believed to be more highly 'evolved' than our chimpanzee cousins. But in at least one sense that isn't true, say geneticists who have hunted for the hallmarks of natural selection in our respective genomes - and found more of them in chimps.

  7. Stanford Scientists Make Major Breakthrough In Regenerative Medicine, Biology News Net Next Article Bookmark and Share

    Excerpts: Findings described in a new study by Stanford scientists may be the first step toward a major revolution in human regenerative medicine - a future where advanced organ damage can be repaired by the body itself. In the May 2007 issue of The FASEB Journal, researchers show that a human evolutionary ancestor, the sea squirt, can correct abnormalities over a series of generations, suggesting that a similar regenerative process might be possible in people.

    1. Moving Toward Designer Genes, Time Next Article Bookmark and Share

      Excerpts: DNA research steps up from the cell to the animal Since scientists first began manipulating genes, they have been envisioning a brave new world in which diseases from Huntington's chorea to sickle-cell anemia to possibly diabetes could be cured simply by inserting the correct strip of DNA into the body's cells. So far, though, most of the genetic tinkering has been limited to transplanting genes into isolated cells in laboratory dishes or into bacteria.

  8. Social Science: The Urban Organism, Nature Next Article Bookmark and Share

    Excerpts: Visitors to the area around Nature's London offices will be familiar with the scene: unending traffic and noise; the hurly-burly of the Underground; streets, concourses and platforms filled with people intent only on reaching their destination quickly. It's received wisdom that the bigger a city is, the faster life moves; Luis Bettencourt and colleagues supply some empirical evidence to back up that perception (Proc. Natl Acad. Sci. USA 104, 7301-7306; 2007).

  9. Damage To The Prefrontal Cortex Increases Utilitarian Moral Judgements, Nature Next Article Bookmark and Share

    Excerpts: Of central interest is whether emotions play a causal role in moral judgement, and, in parallel, how emotion-related areas of the brain contribute to moral judgement. Here we show that six patients with focal bilateral damage to the ventromedial prefrontal cortex (VMPC), a brain region necessary for the normal generation of emotions and, in particular, social emotions, produce an abnormally ‘utilitarian' pattern of judgements on moral dilemmas that pit compelling considerations of aggregate welfare against highly emotionally aversive behaviours (for example, having to sacrifice one person's life to save a number of other lives).

    1. Violent Justice: Adult System Fails Young Offenders, Science News Next Article Bookmark and Share

      Excerpts: State laws that send some individuals under age 18 to trial and prison as adults have achieved the opposite of what the policy's proponents intended, a new research review concludes. Transferring young people into adult systems yields substantially higher rates of later serious crimes compared with youths handled by juvenile-justice systems.

      Moreover, there's no evidence that shifting some young offenders to the adult-justice system prevents or reduces violence in the general population of children and teenagers.

  10. China's One-child Policy Reveals Complexity, Effectiveness, ScienceDaily Next Article Bookmark and Share

    Excerpts: The first systematic examination of China's fertility policy and practice reveals that, despite government exemptions in rural areas, 63 percent of Chinese couples are strictly limited to one child. Furthermore, the policy has proven remarkably effective, with actual birth rates decreasing nearly to the mandated levels. (...) the study reveals the complexity of the one-child policy. For example, it details the kinds of exceptions within prefectures for couples who give birth to a girl first, and for parents who themselves come from a one-child family. "The system of exemptions resembles the American tax code in its complexity," Wang said. (...)

  11. Adaptive Memory: Survival Processing Enhances Retention, J. Experi. Psycho.: Learning, Mem. & Cogn. Next Article Bookmark and Share

    Excerpts: The authors investigated the idea that memory systems might have evolved to help us remember fitness-relevant information-specifically, information relevant to survival. In 4 incidental learning experiments, people were asked to rate common nouns for their survival relevance (e.g., in securing food, water, or protection from predators); in control conditions, the same words were rated for pleasantness (...). In surprise retention tests, participants consistently showed the best memory when words were rated for survival; (...). These findings suggest that memory systems are "tuned" to remember information that is processed for fitness, perhaps as a result of survival advantages accrued in the past.

    1. Neuronal Competition and Selection During Memory Formation, Science Next Article Bookmark and Share

      Excerpts: During formation of a memory in a fearful situation, rat neurons with higher amounts of the transcription factor CREB are recruited for selective enhancement.

      Competition between neurons is necessary for refining neural circuits during development and may be important for selecting the neurons that participate in encoding memories in the adult brain. To examine neuronal competition during memory formation, we conducted experiments with mice in which we manipulated the function of CREB (adenosine 3',5'-monophosphate response element-binding protein) in subsets of neurons.

    2. Scientists Identify Genes Activated During Learning And Memory, Innovations-report Next Article Bookmark and Share

      Excerpts: Researchers have long recognized that for learning and memory to take place, certain genes must be activated to alter neuron activity inside the brain. Disruptions in normal gene expression within these neurons can lead to alarming consequences, such as seizures and epilepsy. But identifying and cataloging all the genes involved in learning is a daunting task. (...) "We also expect this work to provide a valuable platform for any investigator to understand how neurons change at the molecular level during learning and the formation of memory." As an animal learns and remembers, specific neurons inside its brain are activated. (...)

  12. Reconnaissance And Latent Learning In Ants, Proc. Biol. Sc. Next Article Bookmark and Share

    Excerpts: (...) Initially, we presented colonies with a new nest of lower quality than their current one that they could explore for one week without a need to emigrate. We then introduced a second identical low quality new nest and destroyed their old nest so that they had to emigrate. Colonies showed a highly significant preference for the (low quality) novel new nest over the identical but familiar one. (...) These results demonstrate for the first time that ants are capable of assessing and retaining information about the quality of potential new nest sites, (...).

    1. Virus Infection Causes Specific Learning Deficits In Honeybee Foragers, Proc. Biol. Sc. Next Article Bookmark and Share

      Excerpts: In both mammals and invertebrates, virus infections can impair a broad spectrum of physiological functions including learning and memory formation. In contrast to the knowledge on the conserved mechanisms underlying learning, the effects of virus infection on different aspects of learning are barely known. We use the honeybee (Apis mellifera), a well-established model system for studying learning, to investigate the impact of deformed wing virus (DWV) on learning. (...) Thus, DWV seems to interfere with molecular mechanism of learning by yet unknown processes that may include viral effects on the immune system and on gene expression.

  13. Neuroscience: Astrocytes Secrete Substance That Kills Motor Neurons in ALS, Science Next Article Bookmark and Share

    Excerpts: Astrocytes--among the glial, or "support," cells in the central nervous system--may be the primary culprit in the death of motor neurons in at least some cases of amyotrophic lateral sclerosis (ALS), researchers at Harvard and Columbia universities report. The new findings underscore the power of research with embryonic stem (ES) cells to elucidate basic disease processes, the researchers say.

  14. Fruit Proves Better Than Vitamin C Alone, Nature Next Article Bookmark and Share

    Excerpts:
    If you're after an antioxidant, try oranges
    If you're in the market for an antioxidant to keep your body young and healthy, new research suggests you'd be much better off with oranges than vitamin C tablets.

    Although vitamin C is best known for its protection against scurvy and, possibly, the common cold (see 'Vitamin C best in the cold'), fruits rich in vitamin C are also powerful antioxidants that protect cellular DNA from being damaged by oxidation. Going without such foods leads to DNA damage long before the iconic bleeding gums of scurvy are seen.

  15. Neurobiology: Feeling Right About Doing Right, Nature Next Article Bookmark and Share

    Excerpts: Reason and emotion come into conflict in making all kinds of judgements. Results of work with brain-damaged patients constitute one line of evidence that the emotional component is not to be dismissed.

    In resolving moral dilemmas, should emotion be our guide? This is a question prompted by various research avenues, including work described in the paper by Koenigs et al. on page 908 of this issue.

  16. Male and Female Drosophila Germline Stem Cells: Two Versions of Immortality, Science Next Article Bookmark and Share

    Excerpts: Drosophila male and female germline stem cells (GSCs) are sustained by niches and regulatory pathways whose common principles serve as models for understanding mammalian stem cells. Despite striking cellular and genetic similarities that suggest a common evolutionary origin, however, male and female GSCs also display important differences. Comparing these two stem cells and their niches in detail is likely to reveal how a common heritage has been adapted to the differing requirements of male and female gamete production.

  17. Nanoscale 'Coaxial Cables' for Solar Energy Harvesting, PhysOrg.com Next Article Bookmark and Share

    Excerpts:
    A cross-section of the nanoscale coaxial cable, in which nitrogen, phosphorus, and gallium atoms are shown in blue, yellow, and magenta, respectively. White spheres represent hydrogen atoms, which help render the surface of the wire chemically non-reactive.
    Scientists have designed a new type of nanowire - a tiny coaxial cable - that could vastly improve a few key renewable energy technologies, particularly solar cells, and could even impact other cutting-edge, developing technologies, such as quantum computing and nanoelectronics. (...) When electrons in these materials are excited by light and jump to higher energy levels (leaving vacancies, known as "holes" in the lower levels), both the electrons and the holes typically move around in the same region.(...)

  18. Biochemistry: An Ancient and Intimate Partnership, Science Next Article Bookmark and Share

    Excerpts: Before the evolution of photosynthesis ~3.5 billion years ago, Earth's atmosphere was reducing, and iron was mainly in its Fe(II) oxidation state. The abundant Fe(II) soaked up the early molecular oxygen generated by photosynthesis. Complex multicellular organisms could not evolve until substantial amounts of oxygen became available in Earth's atmosphere ~2 billion years ago. Then the tables were turned: Organisms used Fe(II) to access the oxidative power of molecular oxygen, thus dramatically increasing the efficiency of metabolic energy generation.

    2. Ecology: Rapid Domestication of Marine Species, Science Next Article Bookmark and Share

      Excerpts: About 11,000 years ago, humans began to domesticate plants and animals (1-3). In the next 9000 years, hundreds of land species and a few aquatic species were domesticated. Since then, however, few land species have been domesticated. In contrast, the domestication of aquatic--particularly marine--species has grown exponentially. Aquaculture is emerging as a revolution in agriculture of global importance to humankind.

      Excerpts: Scotland Yard's head of counter-terrorism command has warned that al-Qaida has retained the ability to order devastating attacks on Britain after surviving the six-year long "war on terror" launched by the US and UK governments.

      Deputy assistant commissioner Peter Clarke said that terrorists were on an "inexorable trend to more ambitious and more destructive attack planning".

      "We have seen how al-Qaida has been able to survive a prolonged multinational assault on its structures, personnel and logistics. It has certainly retained its ability to deliver centrally directed attacks here in the UK," Clarke warned.

    2. In Somalia, Those Who Feed Off Anarchy Fuel It, NY Times Next Article Bookmark and Share

      Excerpts: Beyond clan rivalry and Islamic fervor, an entirely different motive is helping fuel the chaos in Somalia: profit.

      A whole class of opportunists = from squatter landlords to teenage gunmen for hire to vendors of out-of-date baby formula - have been feeding off the anarchy in Somalia for so long that they refuse to let go.

      They do not pay taxes, their businesses are totally unregulated, and they have skills that are not necessarily geared toward a peaceful society.
