  1. Neuroeconomics: Best To Go With What You Know?, Nature Next Article Bookmark and Share

    Excerpts: In a changing world, how do we decide our best option? How do we settle between picking something familiar or trying out a new, possibly more rewarding, choice?

    You step into a music store: how do you choose which CD to buy? If you pick something by your favourite composer, Schubert say, you know you will enjoy it. But you might want to expand your repertoire by trying a less familiar piece, for example Mahler's symphony No. 10. You might not like it; on the other hand, you might discover a new favourite. So how do you decide between sticking with what you know and like, and trying something more adventurous that might prove even more rewarding?

  2. Neurons Find Strength Through Synchrony In The Brain, Science Next Article Bookmark and Share

    Excerpts: Cortex Is Driven by Weak but Synchronously Active Thalamocortical Synapses http://www.sciencemag.org/cgi/content/full/312/5780/1622 Randy M. Bruno and Bert Sakmann Science 16 June 2006: 1622-1627. Electrical recordings from cortical neurons in living rodents show that the numerous sensory inputs to these cells are individually weak but very effective because they act synchronously.

    1. Cortex Is Driven by Weak but Synchronously Active Thalamocortical Synapses, Science Next Article Bookmark and Share

      Excerpts: Sensory stimuli reach the brain via the thalamocortical projection, a group of axons thought to be among the most powerful in the neocortex. Surprisingly, these axons account for only 15% of synapses onto cortical neurons. The thalamocortical pathway might thus achieve its effectiveness via high-efficacy thalamocortical synapses or via amplification within cortical layer 4. In rat somatosensory cortex, we measured in vivo the excitatory postsynaptic potential evoked by a single synaptic connection and found that thalamocortical synapses have low efficacy.

  3. Reaching A Tipping Point, Nature Next Article Bookmark and Share

    Excerpts: A popular new paradigm for the nature of change pertains more to the social and political worlds than it does to the physical one. (...)

    The physical, chemical and biological responses that turn greenhouse gases into climate change are complex and subtle, and capable of responses that are surprisingly disproportionate. There are thresholds beyond which the past response of the system no longer predicts the future, and there are positive feedbacks through which change can feed on itself. All these possibilities are now being discussed under the rubric of tipping points.

    1. Climate Change: The Tipping Point Of The Iceberg, Nature Next Article Bookmark and Share

      Excerpts: Could climate change run away with itself?(...)

      Although there's no strong evidence that the climate as a whole has a point beyond which it switches neatly into a new pattern, individual parts of the system could be in danger of changing state quickly, and perhaps irretrievably. And perhaps the most striking of these vulnerable components are in the Arctic. Farthest north is the carapace of sea ice over the Arctic Ocean. South of that is the vast ice sheet that covers Greenland. And then there is the ocean conveyor belt, which originates in a small region of the Nordic seas and carries heat and salt around the world.

    2. Burst Of Energy, Nature Next Article Bookmark and Share

      Excerpts: More and more venture capitalists are backing clean technology in the United States, but will it take off? (...)

      One reason for caution is the shortage of entrepreneurs or investors who understand the nuances and complexities of the sector. "People want to see a lot happen," says Lynd, "but there are not that many competent people to make it happen." And some analysts think that the venture capitalists are already overfunding projects. "There is a lot of dumb money out there," (...).

  4. The Emergence Of Local Norms In Networks, Complexity Next Article Bookmark and Share

    Abstract: We develop an explanation of the emergence of local norms and the associated phenomenon of geographical variation in behavior. Individuals are assumed to interact locally with neighbors in an environment with a network externality. Although many patterns of behavior are possible, the dispersed interactive choices of agents are shown to select behavior that is locally uniform but globally diverse. The range of applications of the theory includes regional variation in the practice of medicine, technology choice, and corruption. The framework is also useful for further developing our understanding of important phenomena like lock-in, critical thresholds, and contagion.

  5. Economic View - Immigration Math: It's a Long Story, NY Times Next Article Bookmark and Share

    Excerpts: Much of today's debate about immigration revolves around the same old questions: How much do immigrants contribute to production? Do they take jobs away from people born in the United States? And what kinds of social services do they use? Yet every immigrant represents much more than just one worker or one potential citizen. To understand fully how immigration will shape the economy, you can't just look at one generation - you have to look into the future.

  6. Japanese Store Hires Robot Staff, vnunet.com Next Article Bookmark and Share

    Excerpts: A robot sales assistant started work for the first time at a Japanese department store on Saturday morning. The 130cm high machine is able to guide customers around the store's supermarket section and carry shopping, according to its manufacturer, Fujitsu. The first robot employee, dubbed 'Enon', will work every Saturday and Sunday from 10am to 6pm at the Jusco department store (...). Fujitsu said that 'Enon' can speak and respond to spoken commands. It uses multiple cameras and ultrasonic sensors to locate customers and avoid obstacles, and has a pre-programmed map of the store layout. (...)

  7. Cash For Papers: Putting A Premium On Publication, Nature Next Article Bookmark and Share

    Excerpts: Trend for financial incentives spreads in Asia.

    Financial rewards for publishing high-profile papers are spreading. Starting later this month, South Korean researchers will receive US$3,000 from the government when they publish in elite journals. And that's a pittance compared with China, where some scientists can rake in more than ten times that amount.

    As institutions and countries strive for international recognition, some are hoping that publication bonuses will help. But critics fear that this strategy could lead to a dangerous fixation on a few indicators of scientific success.

    1. Goals And Means In Action Observation: A Computational Approach, Neural Networks Next Article Bookmark and Share

      Excerpts: Many of our daily activities are supported by behavioural goals that guide the selection of actions, which allow us to reach these goals effectively. Goals are considered to be important for action observation since they allow the observer to copy the goal of the action (...). The importance of being able to use different action means becomes evident when the observer and observed actor have different bodies (robots and humans) or bodily measurements (parents and children) (...). In this paper, we use a computational approach to investigate how knowledge about action goals and means are used in action observation. (...)

  8. Growing Up Online, Science News Next Article Bookmark and Share

    Excerpts: As a conversation unfolds among teenagers on an Internet message board, it rapidly becomes evident that this is not idle electronic chatter. One youngster poses a question that, to an outsider, seems shocking: "Does anyone know how to cut deep without having it sting and bleed too much?" An answer quickly appears: "I use box cutter blades. You have to pull the skin really tight and press the blade down really hard." Another response advises that a quick swipe of a blade against skin "doesn't hurt and there is blood galore.

    1. Growing Wikipedia Revises Its 'Anyone Can Edit' Policy, NY Times Next Article Bookmark and Share

      Excerpts: Wikipedia is the online encyclopedia that "anyone can edit." Unless you want to edit the entries on Albert Einstein, human rights in China or Christina Aguilera. Wikipedia's come-one, come-all invitation to write and edit articles, and the surprisingly successful results, have captured the public imagination. But it is not the experiment in freewheeling collective creativity it might seem to be, because maintaining so much openness inevitably involves some tradeoffs.

  9. Positive Natural Selection in the Human Lineage, Science Next Article Bookmark and Share

    Excerpts: Positive natural selection is the force that drives the increase in prevalence of advantageous traits, and it has played a central role in our development as a species. Until recently, the study of natural selection in humans has largely been restricted to comparing individual candidate genes to theoretical expectations. The advent of genome-wide sequence and polymorphism data brings fundamental new tools to the study of natural selection. It is now possible to identify new candidates for selection and to reevaluate previous claims by comparison with empirical distributions of DNA sequence variation across the human genome and among populations.

    1. Fossil Embryos Hint at Early Start for Complex Development, Science Next Article Bookmark and Share

      Excerpts: Evidence of the earliest animals on Earth dates back about 700 million years. But the arrival time of more complex animals--those with mirror symmetry and digestive tracts, known as bilaterians--has remained a mystery.

      Now, (...), an international team of paleontologists says it has isolated hundreds of fossil embryos that resemble those of modern bilaterians such as annelids and mollusks. If they check out, it could mean that a wide array of complex animals existed tens of millions of years before the "Cambrian explosion"--the time when paleontologists think hard-bodied animals proliferated as their ecosystems took shape.

    2. China Fossils Fill Out Bird Story, BBC Next Article Bookmark and Share

      Excerpts:
      An artist's impression of Gansus yumenensis on the Cretaceous lake that is now the Changma Basin of northwestern Gansu Province, China. Despite its antiquity, Gansus is remarkably closely related to modern birds. Image: Mark A Klingler/CMNH)
      Exquisite Chinese fossils support the idea that the ancestors of modern birds may have lived on water. Five 110-million-year-old specimens of the grebe-like Gansus yumenensis are described in the journal Science.

      The detail in their preservation, such as the bone structure and even foot webbing, indicates the animals were well adapted to an aquatic existence.

      Scientists say Gansus is the oldest known member of the group that includes modern birds.

    3. Amphibious Ancestors, Science News Next Article Bookmark and Share

      Excerpts: Newly discovered fossils from Greenland, as well as a reexamination of those of previously known creatures, are providing researchers with additional insights into ancient vertebrates' move from water to land.

  10. Cascades of Failure and Extinction in Evolving Complex Systems, arXiv Next Article Bookmark and Share

    Excerpts: There is empirical evidence from a range of disciplines that as the connectivity of a network increases, we observe an increase in the average fitness of the system. But at the same time, there is an increase in the proportion of failure/extinction events which are extremely large. The probability of observing an extreme event remains very low, but it is markedly higher than in the system with lower degrees of connectivity. We give examples from complex systems such as outages in the US power grid, the robustness properties of cell biology networks, and trade links and the propagation of both currency crises and disease. (...) We find that increasing the number of connections causes an increase in the average fitness of agents, yet at the same time makes the system as whole more vulnerable to catastrophic failure/extinction events on an near-global scale.

  11. Immunology: Discriminating Microbe from Self Suffers a Double Toll, Science Next Article Bookmark and Share

    Excerpts: Sensing microbial infection and countering it with a vigorous immune reaction is a double-edged challenge facing all multicellular organisms. Mobilizing a swift immune response to viruses and bacteria is often a critical survival advantage. However, many microbial components are chemically similar to constituents of our own cells, and failure to tell the two apart leads to devastating autoimmune reactions against self. The fine line that the immune system treads between antimicrobial immunity and autoimmunity is highlighted in reports by Pisitkun et al. on page 1669 of this issue (1)and by Kumar et al. on page 1665 (2).

    1. Neurodegeneration: Good Riddance To Bad Rubbish, Nature Next Article Bookmark and Share

      Excerpts: Autophagy - cellular 'self-eating' - can be induced by stress, but it also acts continuously in a housekeeping role, disposing of unwanted proteins. Can it protect against neurodegenerative diseases?

      Alzheimer's, Parkinson's and Huntington's diseases are names we hear with a certain dread. These devastating illnesses, typically associated with ageing, result from the death of neurons. The cause of cell death is not known, but the onset of the disease symptoms is often accompanied by the appearance of large aggregates of particular proteins, such as A in Alzheimer's, -synuclein in Parkinson's, or huntingtin in Huntington's disease1. These are normal proteins - everyone has them - although their function is not always clear.

  12. Cleaner Can Mean Sicker, Studies Assert, Associated Press Next Article Bookmark and Share

    Excerpts: Gritty rats and mice living in sewers and farms seem to have healthier immune systems than their squeaky clean cousins in cushy antiseptic labs, two studies indicate.

    The studies give more weight to a 17-year-old theory that the sanitized Western world may be partly to blame for soaring rates of human allergy and asthma cases and some autoimmune diseases, such as Type I diabetes and rheumatoid arthritis.

    1. Wild Vs. Lab Rodent Comparison Supports Hygiene Hypothesis, Eurekalert Next Article Bookmark and Share

      Excerpts: In a study comparing wild rodents with their laboratory counterparts, researchers at Duke University Medical Center have found evidence that may help to explain why people in industrialized societies that greatly stress hygiene have higher rates of allergy and autoimmune diseases than do people in less developed societies in which hygiene is harder to achieve or considered less critical.

      The prevailing hypothesis concerning the development of allergy and probably autoimmune disease is the "hygiene hypothesis,(...)

  13. Food-Caching Western Scrub-Jays Keep Track of Who Was Watching When, Science Next Article Bookmark and Share

    Excerpts: Western scrub-jays (Aphelocoma californica) hide food caches for future consumption, steal others' caches, and engage in tactics to minimize the chance that their own caches will be stolen. We show that scrub-jays remember which individual watched them during particular caching events and alter their recaching behavior accordingly. We found no evidence to suggest that a storer's use of cache protection tactics is cued by the observer's behavior.

  14. A Viral Drive to Survive, ScienceNOW Next Article Bookmark and Share

    Excerpts:
    Boom or bust.
    Viruses turn their bacterial hosts into viral replication factories, but they are more likely to die as "offspring" numbers soar.
    Credit: STEPHANIE TIMMERMANN
    So most living things make a tradeoff, producing enough young to effectively pass on their genes without sacrificing too much of their own life span. The strategy is so universal, it even extends to nonliving entities such as viruses, according to a new study.(...)

    The team thinks that as viruses push to increase their numbers, the bacteria's machinery struggles to keep up and does shoddier work. "It's a case of quality versus quantity," says Taddei. These second-rate viruses are likely less able to infect bacteria, leading to less viral offspring.

    1. Turning a Tumor's Lights Off, ScienceNOW Next Article Bookmark and Share

      Excerpts: When Olympic sprinters push themselves to the limit, the energy-producing pathways in their cells switch gears, turning to an oxygen-free pathway to keep the juice flowing. Cancer cells also use this pathway--called anaerobic glycolysis--even when there is plenty of oxygen around. Now, researchers have found that blocking a key enzyme involved in anaerobic glycolysis significantly slows the growth of tumors. The findings, say experts, suggest a new way to target cancer with drugs.

  15. Is there an Elegant Universal Theory of Prediction?, arXiv Next Article Bookmark and Share

    Abstract: Solomonoff's inductive learning model is a powerful, universal and highly elegant theory of sequence prediction. Its critical flaw is that it is incomputable and thus cannot be used in practice. It is sometimes suggested that it may still be useful to help guide the development of very general and powerful theories of prediction which are computable. In this paper it is shown that although powerful algorithms exist, they are necessarily highly complex. This alone makes their theoretical analysis problematic, however it is further shown that beyond a moderate level of complexity the analysis runs into the deeper problem of Goedel incompleteness. This limits the power of mathematics to analyse and study prediction algorithms, and indeed intelligent systems in general.

  16. Researchers Offer Clues To How Leaves Patterns Are Formed, ScienceDaily Next Article Bookmark and Share

    Excerpts: Pick up a leaf and it is hard not to notice the pattern made by the veins. For years, biologists, mathematicians and even poets and philosophers have tried to decipher the rules and regulations behind those varied designs and now new research (...) offers a big clue to how those patterns are formed. (...) "We were able to connect the mechanism responsible for the initiation of the veins in the leaf with that of formation of the shoot and root. With our piece of the puzzle added, it indeed seems the same mechanism is responsible for all these events." (...)

    Excerpts:
    Butterfly blend. Two different butterfly species apparently mated to create a third in the South American Andes.
    Credit: Mauricio Linares, Uniandes, Colombia
    Like merging two companies to create a joined venture, scientists have bred two colorful butterfly species to form an intermediate type, perhaps duplicating a feat nature has already accomplished. This speciation process, known as hybridization, may play a larger role in evolution than is currently believed, the researchers propose.

  18. Solid-State Chemistry: A Glass Of Carbon Dioxide, Nature Next Article Bookmark and Share

    Excerpts: Carbon is unusual in its family of elements because it has gaseous oxides. But under high pressure, carbon dioxide forms crystalline solids and can become a glass - so revealing the chemical family resemblance. (...)

    The newly prepared materials might have useful properties for technological applications. Studies on the polymeric, silica-like form of CO2 suggest that it is 'super-hard' and that it is an optically nonlinear material - for example, it causes doubling of the frequency of light from a laser4, 5. The discovery also has implications for geochemistry, because the conditions found in Earth's mantle could induce the formation of these newly discovered forms of carbon oxides.

    1. What Can a Magnet Tell You About Rain Patterns? More Than You Would Guess, UCLA News Next Article Bookmark and Share

      Excerpts: f someone said you can understand rain patterns and the dynamics of the atmosphere by studying magnets and magnetism - and therefore make better predictions of the effects of global warming - would you think he's crazy? Brilliant? The atmosphere spans the entire globe, while a magnet fits easily in your hand; can they really be so similar?

      Ole Peters, a 27-year-old physicist with expertise in "critical phenomena" and "self?organized criticality" - which he acknowledges is "a bit of a rogue field" - doesn't sound the least bit crazy.

      In the June issue of the respected journal Nature Physics, he and J. David Neelin, UCLA professor of atmospheric and oceanic sciences, report that the onset of intense tropical rain and magnetism share the same underlying physics.

    2. An Atomic Odd Couple, ScienceNOW Daily News Next Article Bookmark and Share

      Excerpts:
      Shove off. Like eggs in a carton, atoms nestle into the regular pattern of bright spots in an optical lattice. A new experiment shows that within such a "light crystal," two atoms can get stuck together even though they repel each other.
      "If something wants to decay, it needs a state to decay into," explains Wolfgang Ketterle, an experimenter at the Massachusetts Institute of Technology in Cambridge. Lacking such a state, the pairs of atoms have no choice but to stay together. Jason Ho, a theorist at Ohio State University in Columbus, says the result could lead to even stranger things if it's possible to "condense" the pairs into a single quantum wave.

    1. Casualty Dynamics in Wars and Terrorism and the Scale-Free Organization of Social Systems, ArXiv Next Article Bookmark and Share

      Excerpts: Abstract

      In this paper I propose a 'mechanism' for the explanation of power-law characteristics of casualty dynamics in inter-state wars, intra-state wars and terrorist attacks: the scale-free physical organization of social systems. Other explanations - self-organized criticality (Cederman, 2003) and the redistribution of total attack capabilities (Johnson et al. 2006) - do not provide a consistent framework for the power-law characteristics of casualty dynamics. The development in time of the power-law characteristics of casualty dynamics during wars and conflicts provides clues for the 'functioning' of social systems which are targeted, and/or for the (in)effectiveness and strategies of actors using force (violence) against these social systems.

      Excerpts: Somalia is now a critical test for the CIA. The agency must develop independent or unilateral operations there, or at the very least reduce its dependency on foreign intelligence agencies. So far, both have proven exceedingly difficult. The problem isn't limited to Somalia, obviously. The CIA's network is said to be exceedingly thin in Iran and other countries of significance in the war on terror. Insofar as Mr. Kappes can take steps in that direction in Somalia, he will be moving in the right direction on a global problem.
