  1. Internet Traffic Begins to Bypass the U.S., NY Times Next Article Bookmark and Share

    Excerpts: The era of the American Internet is ending.

    Invented by American computer scientists during the 1970s, the Internet has been embraced around the globe. During the network's first three decades, most Internet traffic flowed through the United States. In many cases, data sent between two locations within a given country also passed through the United States.

    Engineers who help run the Internet said that it would have been impossible for the United States to maintain its hegemony over the long run because of the very nature of the Internet; it has no central point of control.

  2. Human Behaviour: Share And Share Alike, Nature Next Article Bookmark and Share

    Excerpts: The happy tendency to share resources equitably - at least with members of one's own social group - is a central and unique feature of human social life. It emerges, it seems, in middle childhood.

    Recent experiments have shown that chimpanzees do not take advantage of cost-free opportunities to deliver food to other members of their group. Nor do they prevent others from getting food when they could easily do so. In most situations, our nearest primate relatives seem to be focused exclusively on the food that they themselves might get.

    1. Battle Of The Sexes May Set The Brain, Nature Next Article Bookmark and Share

      Excerpts: A tug-of-war between the mother's and father's genes in the developing brain could explain a spectrum of mental disorders from autism to schizophrenia, (...).

      We believe that psychiatric illness may be less to do with the genes a mother and father pass down, and more to do with which genes they program for expression. By our hypothesis, a hidden battle of the sexes - where a mother's egg and a father's sperm engage in an evolutionary struggle to turn gene expression up or down - could play a crucial part in determining the balance or imbalance of an offspring's brain.

  3. The Early Years: Preschool Influences On Mathematics Achievement, Science Next Article Bookmark and Share

    Excerpts: The advantages of home learning environment (HLE) and preschool are apparent years later in children's math achievement. (...)

    The HLE, preschool effectiveness, and primary school effectiveness all showed significant effects on children's mathematics achievement at age 10 (P < 0.001).Total variance accounted for was 22%. (...)

    The HLE had low correlations with parents' socioeconomic status or education (r = 0.28 to 0.32) and showed independent effects slightly less than mother's education but greater than father's education and family income. This indicates that what parents do is as important as who parents are.

  4. The Odds It Will Kill You? See New Charts, NY Times Next Article Bookmark and Share

    Excerpts:
    Copyright 2008 The New York Times Company
    New risk charts in a paper published in The Journal of the National Cancer Institute provide a broader perspective than most of the risk calculators on the Internet, because they cover the risks for 10 different causes of death, and for all causes combined, while differentiating by age and between smokers, nonsmokers and former smokers.

    At first glance, it may appear that smokers and nonsmokers die of heart disease at the same rate, but a 35-year-old male smoker is seven times as likely to die of heart disease as a nonsmoker the same age. The numbers begin to converge as some smokers survive the more common smokers' diseases, and by age 75, their rate of death from heart disease is almost the same as nonsmokers'.

    1. How Much Risk Can You Handle? Making Better Investment Decisionse, ScienceDaily Next Article Bookmark and Share

      Excerpts: Many Americans make investment decisions with their retirement funds. But they don't always make informed judgments. A new (...) introduces a new tool that investors can use to choose investments based on their financial goals and risk attitudes. (...) developed a tool, which they call the Distribution Builder. With brief training, people can use the Distribution Builder to better understand their investment goals and trade-offs. (...) Since many employees make retirement investment decisions without understanding the complex picture of their own risk preferences, the Distribution Builder is a novel way for people to uncover their preexisting preferences.

  5. Social Learning Strategies And Predation Risk, Proc. Biol. Sc. Next Article Bookmark and Share

    Excerpt: Animals can acquire information from the environment privately, by sampling it directly, or socially, through learning from others. Generally, private information is more accurate, but expensive to acquire, while social information is cheaper but less reliable. Accordingly, the ‘costly information hypothesis' predicts that individuals will use private information when the costs associated with doing so are low, but that they should increasingly use social information as the costs of using private information rise. While consistent with considerable data, this theory has yet to be directly tested in a satisfactory manner. We tested this hypothesis by giving minnows (Phoxinus phoxinus) a choice (...).

  6. War And The Evolution Of Belligerence And Bravery, Proc. Biol. Sc. Next Article Bookmark and Share

    Excerpt: Tribal war occurs when a coalition of individuals use force to seize reproduction-enhancing resources, and it may have affected human evolution. Here, we develop a population-genetic model for the coevolution of costly male belligerence and bravery when war occurs between groups of individuals in a spatially subdivided population. Belligerence is assumed to increase an actor's group probability of trying to conquer another group. An actor's bravery is assumed to increase his group's ability to conquer an attacked group. We show that the selective pressure on these two traits can be substantial even in groups of large size, (...).

  7. Archaeology: Ancient Earthmovers Of The Amazon, Science Next Article Bookmark and Share

    Excerpts: The forested western Amazon was once thought barren of complex human culture. But researchers are now uncovering enigmatic earthworks left by large, organized societies that once lived and farmed here. (...)

    Shaped like circles, diamonds, hexagons, and interlocking rectangles, the geoglyphs are 100 to 350 meters in diameter and outlined by trenches 1 to 7 meters deep. Many are approached by broad earthen avenues, some of them 50 meters wide and up to a kilometer long.

    1. Archaeology: The Western Amazon's "Garden Cities", Science Next Article Bookmark and Share

      Excerpts: (...) finding a set of urban settlements startlingly similar to Howard's garden cities--built in the forests of the south-central Amazon as early as 1250 C.E.

      The paper identifies dozens of densely packed "towns, villages, and hamlets" covering perhaps 30,000 square kilometers--an area the size of Belgium--in the headwaters of the Xingu River. The settlements, built by indigenous peoples, were tied together by "well-planned road networks" and embedded in a matrix of agricultural land.

  8. Developmental Biology: Neuron Research Leaps Ahead, Science Next Article Bookmark and Share

    Excerpts: Technologies that reprogram adult dermal cells into motor neurons should advance our understanding of neurodegenerative diseases. (...)

    Dimos et al. not only demonstrate that human neural cells--in particular, disease-related neural cells--can be generated from induced pluripotent stem cells, but also that the method can be successfully applied to fibroblasts derived from elderly patients, a key issue for age-dependent disorders (like most of the neurodegenerative diseases). Moreover, the study shows the feasibility of producing large numbers of induced pluripotent stem cells from a small skin biopsy.

    1. New Insights On New Neurons, Science News Next Article Bookmark and Share

      Excerpts: Two studies on mice shed light on the role of neurogenesis in memory, olfactory sensing and antidepressant efficacy.

      Most of the brain does fine with its original brain cells, but parts involved in smelling and remembering sometimes need some new recruits.

      In mice, new neurons are needed to remember mazes and keep their scent-sensing organs plump (but aren't necessary for detecting smells), a new study shows. Another recent study demonstrates that some antidepressants require neurogenesis - the creation of fresh neurons - to work.

  9. Memory Trick Shows Brain Organization, ScienceDaily Next Article Bookmark and Share

    Excerpts: A simple memory trick has helped show UC Davis researchers how an area of the brain called the perirhinal cortex can contribute to forming memories. The finding expands our understanding of how those brain areas that form memories are organized. The brain puts together different items -- the what, who, where and when -- to form a complete memory. It was previously thought that this association process occurred entirely in a brain structure called the hippocampus, but this appears not to be the case, said (...). "We want to know how the brain areas that encode memory are organized," Ranganath said. (...)

    1. Number Forms In The Brain, J. Cog. Neurosc. Next Article Bookmark and Share

      Excerpts: Mental images of number lines, Galton's "number forms" (NF), are a useful way of investigating the relation between number and space. Here we report the first neuroimaging study of number-form synesthesia, investigating 10 synesthetes with NFs going from left to right compared with matched controls. (...) revealed no difference in brain activation during a task focused on number magnitude but, in a comparable task on number order, synesthetes showed additional activations (...), suggesting that NFs are essentially ordinal in nature. Our results suggest that there are separate but partially overlapping neural circuits for the processing of ordinal and cardinal numbers, (...).

    2. Physiological Society Meeting: Learning Under Anesthesia, Science Next Article Bookmark and Share

      Excerpts: Summary: Rodents commit the odors of other rodents' meals to the brain as preferred foods using a process known as olfactory learning. At the Physiological Society meeting, researchers reported that this scent-based social learning occurs even when mice are knocked out by anesthesia.

      (...) scent-based social learning occurs even when mice are knocked out by anesthesia. After Nicol fed a mouse coriander-scented food and had it breathe onto the nose of an anesthetized comrade, the unconscious mouse preferred coriander-scented food when it woke up.

  10. New Role For Natural Killers!, Innovations-report Next Article Bookmark and Share

    Excerpts: Scientists (...) have discovered a new role for a population of white blood cells, which may lead to improved treatments for chronic infections and cancer. Natural Killer (or NK) cells are abundant white blood cells that were recognised over 30 years ago as being able to kill cancer cells in the test tube. Since that time, a role for NK cells in activating other white blood cells (including ‘T' lymphocytes and phagocytes) and in directing how the immune system responds to a wide range of infections has also been established. However, (...) has now demonstrated that NK cells also make chemicals that inhibit immune responses. (...)

    1. Loss Of Sleep, Even For A Single Night, Increases Inflammation In The Body, Science Daily Next Article Bookmark and Share

      Excerpts: Loss of sleep, even for a few short hours during the night, can prompt one's immune system to turn against healthy tissue and organs. (...)

      The findings suggest a good night's sleep can ease the risk of both heart disease and autoimmune disorders such as rheumatoid arthritis. Specifically, the researchers measured the levels of nuclear factor (NF)-£eB, a transcription factor that serves a vital role in the body's inflammatory signaling, in healthy adults.

  11. Scientists Discover Why Flies Are So Hard To Swat, ScienceDaily Next Article Bookmark and Share

    Excerpts: Over the past two decades, Michael Dickinson has been interviewed by reporters hundreds of times (...). One question from the press has always dogged him: Why are flies so hard to swat? "Now I can finally answer," says Dickinson, (...). (...) have determined the secret to a fly's evasive maneuvering. Long before the fly leaps, its tiny brain calculates the location of the impending threat, comes up with an escape plan, and places its legs in an optimal position to hop out of the way in the opposite direction. All of this action takes place within about 100 milliseconds after the fly first spots the swatter. (...)

  12. Systems Biology: Reverse Engineering The Cell, Nature Next Article Bookmark and Share

    Excerpts: Borrowing ideas that were originally developed to study electronic circuits, two reports decipher how yeast reacts to changes in its environment by analysing the organism's responses to oscillating input signals. (...)

    Using the microfluidics set-up, they were therefore able to measure the transcriptional response of galactose-utilizing genes to oscillations of glucose concentration at different frequencies. They found that the yeast reacts strongly to slow oscillations in glucose levels, but weakly to fast oscillations.

    1. Plant Science: The "Invisible Hand" Of Floral Chemistry, Science Next Article Bookmark and Share

      Excerpts: Volatile compounds help flowering plants balance attracting pollinators and maximizing overall reproductive success. (...)

      The presence of nicotine decreased the time hummingbirds and hawkmoths spent drinking from individual flowers but increased the number of flowers visited, presumably to satisfy the caloric demands of hovering flight. Conversely, birds and moths visited fewer flowers for longer periods when nectar lacked nicotine, which suggests that the pollinators' interests are best served by extended visits to a few nectar-rich flowers (6). Responses to plants lacking benzyl acetone were more ambiguous.

  13. New Study Shows Solar System is Unique, The Future of Things Next Article Bookmark and Share

    Excerpts: Research conducted by a team of North American scientist shows our solar system is special, contrary to the accepted theory that it is an average planetary system. Using computer simulations to follow the development of planets, it was shown that very specific conditions are needed for a proto-stellar disk to evolve into a solar system-like planetary system. The simulations show that in most cases either no planets are created, or planets are formed and then migrate towards the disk center and acquire highly elliptical orbits.

    Excerpts:
    The strongest North Atlantic hurricanes, such as 2005's Wilma (seen in visible light at left and in false color denoting cloud heights at right), have been getting even stronger in recent years, a new analysis suggests.Full Story Credit: NASA/GSFC/LaRC/JPL, MISR Team
    The researchers found that the largest increases in cyclone peak winds were in the North Atlantic and eastern North Pacific oceans, regions where sea surface temperatures had warmed from 1981 to 2006.

    Cyclones are essentially heat engines that extract power from warm seas, says Kossin. The larger the temperature difference between the ocean surface and the upper atmosphere, the larger a cyclone can become, he notes.

  15. Gaming Evolves, NY Times Next Article Bookmark and Share

    Excerpts:
    The game begins with single-cell microbes and follows them through their evolution into intelligent multicellular creatures, like the Tiktaalik.
    Unlike the typical shoot-them-till-they're-all-dead video game, Spore was strongly influenced by science, and in particular by evolutionary biology. Mr. Wright will appear in a documentary next Tuesday on the National Geographic Channel, sharing his new game with leading evolutionary biologists and talking with them about the evolution of complex life.

    Evolutionary biologists like Dr. Near and Dr. Prum, who have had a chance to try the game, like it a great deal. But they also have some serious reservations. The step-by-step process by which Spore's creatures change does not have much to do with real evolution.

  16. Massive $208 Million Petascale Computer Gets Green Light, NetworkWorld Next Article Bookmark and Share

    Excerpts: The 200,000 processor core system known as Blue Waters got the green light recently as the University of Illinois at Urbana-Champaign and its National Center for Supercomputing Applications (NCSA) said it has finalized the contract with IBM to build the world's first sustained petascale computational system.

    Blue Waters is expected to deliver sustained performance of more than one petaflop on many real-world scientific and engineering applications. (...)

    Blue Waters will be based on what researchers called PERCS (Productive, Easy-to-use, Reliable Computing System). (...)

    According to the NSF the system may be used to study complex processes like the interaction of the Sun's coronal mass ejections with the Earth's magnetosphere and ionosphere; the formation and evolution of galaxies in the early universe; understanding the chains of reactions that occur with living cells; and the design of novel materials.

    1. MIT Develops Network Analysis Tool: Maps Likely Hacking Routes, vnunet.com Next Article Bookmark and Share

      Excerpts: MIT's Lincoln Laboratory has developed a network mapping tool that enables managers to track likely hacking routes. The tool, dubbed NetSPA for Network Security Planning Architecture, scans the network architecture, the individual computers it connects and a list of likely vulnerabilities to generate a threat mitigation program. "It's a matter of what the attacker can get to and in what order," says (...) "If you spend time patching vulnerabilities the attacker can't get to first, you've left your network exposed longer." The software also suggests the quickest way to block off holes effectively and ways to configure the network (...).

    2. Stanford's 'Autonomous' Helicopters Teach Themselves To Fly, PhysOrg.com Next Article Bookmark and Share

      Excerpts:
      Computer Science Professor Andrew Ng (center) and his graduate students Pieter Abbeel (left) and Adam Coates have developed an artificial intelligence system that enables these helicopters to perform difficult aerobatic stunts on the their own. The "autonomous" helicopters teach themselves to fly by watching the maneuvers of a radio control helicopter flown by a human pilot.
      So the researchers had Oku and other pilots fly entire airshow routines while every movement of the helicopter was recorded. As Oku repeated a maneuver several times, the trajectory of the helicopter inevitably varied slightly with each flight. But the learning algorithms created by Ng's team were able to discern the ideal trajectory the pilot was seeking. Thus the autonomous helicopter learned to fly the routine better - and more consistently - than Oku himself.

  17. It's Likely That Times Are Changing, Science News Next Article Bookmark and Share

    Excerpts: But suppose you are studying the universe as a whole, attempting to formulate the laws of quantum gravity that rule the cosmos. There is no wall enclosing the universe on which to hang a clock, no external timekeeper to gauge the whenness of being. Yet quantum physics requires time to tell the universe what to do - time is necessary for things to happen. (...)

    But when deriving that math to begin with, there's no way to know in advance which part corresponds to the master cosmic clock. You have to choose something to represent time from within your equations, Albrecht notes. "Your first job is to identify what you mean by time," he says.

  18. Scientists Grow 'Nanonets' Able To Snare Added Energy Transfer, Science Daily Next Article Bookmark and Share

    Excerpts:
    Researchers at Boston College report creating nanonets, pictured here magnified 50,000 times. The novel nano-scale structure was grown from titanium and silicon in a two-dimensional network of wires that resembles flat, rectangular netting. (Credit: Angewandte Chemie International)
    By creating nanonets, the team conquered a longstanding engineering challenge in nanotechnology: creating a material that is extremely thin yet maintains its complexity, a structural design large or long enough to efficiently transfer an electrical charge. (...)

    Basic nano structures are commonly created in zero or one dimension, such as a dot composed of a small number of atoms. The most complex structures grow in three dimensions - somewhat resembling the branches of a tree. Working in 2D, Wang's team produced a web that under a microscope resembles a tree with all branches growing in the same perpendicular direction from the trunk.

      Excerpts: "The terms of the agreement were that the Palestinian organizations could even maintain armed bases of operation in the country," he wrote, "and they had freedom of entry and exit without being subject to normal police controls, because they were 'handled' by the secret services." Similar deals existed between these groups and the governments of France and Britain. This ugly truth typifies a cancerous, self-preserving opportunism that infects much of Europe to this day. It masquerades in moralistic rhetoric and political correctness - respect for the religion and culture of Muslims and such. But in truth, it's just naked fear.

      2. 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
        Publisher, Complexity Digest
