    Excerpt: Ever since September 11, 2001, security issues have topped the American policy agenda. A critical facet of security policy is the availability of accurate technical information - along with means of transferring that information reliably from the laboratory to policy makers. To facilitate that type of transfer, the American Association for the Advancement of Science has created the AAAS Center for Science, Technology and Security Policy.(...)

    "We want to facilitate the process of getting objective science and technology considerations fully encompassed in the policy process, (...)." [Dr. Norman Neureiter]

    1. Societal Complexity And Diminishing Returns In Security, Int. Security Next Article Bookmark and Share

      Excerpts: (...) There has been little effort, however, to approach the problems that complexity poses for security in a comprehensive way, though this is not to say that work applicable to such a purpose has failed to appear. (...) This article argues that security is becoming an area of diminishing returns to complexity for today's advanced societies because of the diminishing returns from investments in complexity in general, the risks posed by the interconnections this growing complexity creates, and the rising cost of security forces. (...) According to one definition, complexity refers to "asymmetric relationships that reflect organization and restraint" between the parts of a system.(...)
    2. Knowledge As Power: Science, Military Dominance, And U.S. Security, Int. Security Next Article Bookmark and Share

      Excerpts: Can the United States maintain its global lead in science, the new key to its recently unparalleled military dominance? U.S scientific prowess has become the deep foundation of U.S. military hegemony. U.S. weapons systems currently dominate the conventional battlefield because they incorporate powerful technologies available only from scientifically dominant U.S. weapons laboratories. Yet under conditions of globalization, scientific and technical (S&T) knowledge is now spreading more quickly and more widely, suggesting that hegemony in this area might be difficult for any one country to maintain. Is the scientific hegemony that lies beneath U.S. weapons dominance strong and durable, or only weak and temporary? (...)

    Excerpt: "The Chinese are going to become sources of innovation,'' said Denis Fred Simon, a specialist in Chinese science and technology who is provost of the new graduate-level Levin Institute of the State University of New York. "They will find themselves enmeshed in global R.& D. more and more.''

    The starting point for this research boom is China's growing importance and sophistication as a market for technology, especially telecommunications and the Internet, (...).

    "People realize that with the expansion of China's market they need to tailor products to the China market,"(...).

  3. Primary State Formation In Mesoamerica, Annual Review of Anthropology Next Article Bookmark and Share

    Abstract: In this review, we examine the earliest states in Mesoamerica and how they developed. We present a definition of the state and explain why first-generation or primary states have special significance in anthropology and archaeology; we also discuss how anthropological archaeologists can detect the emergence of state organization in the archaeological record. We review the archaeological data bearing on early state formation in Oaxaca, the Southern Gulf Coast, the Southeastern Lowlands, and the Basin of Mexico. Although we acknowledge that more data are needed from all regions, we conclude that Oaxaca currently provides the most compelling evidence of primary state formation in Mesoamerica.
  4. Early Brain Growth In Homo Erectus And Implications For Cognitive Ability, Nature Next Article Bookmark and Share

    Excerpt: An adaptive solution has been reached by giving birth to offspring with relatively small brains compared with adult brain size. Whereas Macaca newborns display an endocranial volume equivalent to 70% of adult size1, the modern human brain represents only 25% of its adult size at birth and continues to grow at its fast fetal rate during the first year of life. At 1 yr of age the human brain is 50% of its adult size and at 10 yr 95% of the adult brain size is achieved.

      Excerpt:
      Sign of foul play. A projectile point (arrow) in a vertebra of an ancient skeleton hints at an early start to human violence.
      Credit: Fanny Bocquentin/Journal Of Human Evolution
      Anthropologists and archaeologists have long suspected that social tensions began to arise after the advent of settled life, when hunter-gatherers formed close-knit communities and eventually took up farming. Yet evidence for this hypothesis has been lacking. The best-studied early sedentary peoples, the Natufians--who occupied parts of present-day Israel beginning about 14,500 years ago--were thought (...) to have been fairly peaceful.

      Now a study of one of the richest collections of Natufian skeletons, from Kebara Cave on Mount Carmel, has turned up fresh evidence of violence among these early settlers.

    2. Humans Not Irrational, Just Wary, ScienceDaily Next Article Bookmark and Share

      Excerpts: Psychologists often conclude from research subjects' behavior in psychological experiments that humans are irrational. New research indicates that humans are in fact quite rational; they just do not trust what people in lab coats tell them. (...) by taking doubt into account, psychologists have the opportunity to strengthen the predictive power of many commonly used models and potentially better understand human behavior. "It may be that subjects are responding in a perfectly adaptive way if you see it through their eyes: this strange experience of walking into a laboratory and meeting someone who tells them to do something they've never done before," (...).
  5. The Body Beautiful: Symbolism and Agency in the Social World, Annual Review of Anthropology Next Article Bookmark and Share

    Excerpt: The prominence of the body in popular culture has prompted intense academic interest in recent decades. Seeking to overturn a naturalistic approach to the body as a biological given, this broad literature redefines the body as a sociocultural and historical phenomenon. Within anthropology, two primary theoretical orientations toward the body have emerged: the body as "symbol" and the body as "agent." (...) The review explores also the body beautiful as a primary site for the construction and performance of gender, and specifically of femininity, (...).
    1. Anthropological Perspectives on Clothing, Fashion, and Culture, Annual Review of Anthropology Next Article Bookmark and Share

      Excerpts: Clothing research has attracted renewed interest in anthropology over the past two decades, experiencing a florescence that had been kept within bounds by reigning theoretical paradigms. (...) The most noticeable trend is a preoccupation with agency, practice, and performance that considers the dressed body as both subject in, and object of, dress practice. The turn to consumption as a site and process of meaning making is evident also in clothing research. Dress has been analyzed, by and large, as representing something else rather than something in its own right, (...).
  6. Music And The Global Order, Annual Review of Anthropology Next Article Bookmark and Share

    Excerpt: The review explores these processes with reference to an anthropological and ethnomusicological account of globalization that has gathered pace over the last decade. It outlines some of the main ethnographic and historical modes of engagement with persistent neoliberal and other music industryinspired global myth making (particularly that associated with world music), and argues for an approach to musical globalization that contextualizes those genres, styles, and practices that circulate across cultural borders in specific institutional sites and histories.
    1. Musical Training Enhances Automatic Encoding Of Melodic Contour, J. Cognitive Neurosc. Next Article Bookmark and Share

      Excerpts: In music, melodic information is thought to be encoded in two forms, a contour code (up/down pattern of pitch changes) and an interval code (pitch distances between successive notes). A recent study (...) demonstrated that people with no formal music education process both contour and interval information in the auditory cortex automatically. However, it is still unclear whether musical experience enhances both strategies of melodic encoding. We designed stimuli to examine contour and interval information separately. (...) The results suggest that musical training enhances the ability to automatically register abstract changes in the relative pitch structure of melodies.
    2. From Visualizing To Proving, Teaching Math. & its Appl. Next Article Bookmark and Share

      Excerpts: The benefits of visualizing mathematics by using technology (...) are indisputable. On the basis of some examples we would like to show that visualizing techniques can help students to analyse certain mathematical problems better and give them strong support in finding formal proofs for considered problems. We present some tasks taken from school algebra, geometry and probability; for these problems it is easier for students to pass the bridge between visual and formal solutions. We conclude that the role of technology is essential in building up associations between graphs, drawings and other tools used for the formal proofs.

    Excerpt:
    Some language rules may be innate
    A new sign language created over the last 30 years by deaf children in Nicaragua has given experts a unique insight into how languages evolve.

    The language follows many basic rules common to all tongues, even though the children were not taught them.

    It indicates some language traits are not passed on by culture, but instead arise due to the innate way human beings process language, experts claim. (...)

    "It shows that children have sophisticated mechanisms of language analysis which give language many of its distinctive qualities."

      Excerpt: We consider a new language invented by deaf children in Nicaragua, and how scientists are able to see the language evolving.
    2. Children Creating Core Properties of Language, Science Next Article Bookmark and Share

      Excerpts: A new sign language has been created by deaf Nicaraguans over the past 25 years, providing an opportunity to observe the inception of universal hallmarks of language. We found that in their initial creation of the language, children analyzed complex events into basic elements and sequenced these elements into hierarchically structured expressions according to principles not observed in gestures accompanying speech in the surrounding language.(...)

      Thus, children naturally possess learning abilities capable of giving language its fundamental structure.

    3. Language Birth And Death, Annual Review of Anthropology Next Article Bookmark and Share

      Excerpt: Since the late 1980s, language endangerment and death have been discussed as if the phenomena had no connection at all with language birth. More recently the phenomena have been associated almost exclusively with the intense and pervasive economic globalization of same period, a process that some authors have reduced too easily to the McDonaldization phenomenon. Moreover, the relation of globalization to different forms of colonization has been poorly articulated. (...) give some broader perspective on the mechanisms of language birth and death (...).
  8. How Would You Feel Versus How Do You Think She Would Feel?, J. Cognitive Neurosc. Next Article Bookmark and Share

    Excerpts: Perspective-taking is a complex cognitive process involved in social cognition. This (...) study investigated by means of a factorial design the interaction between the emotional and the perspective factors. Participants were asked to adopt either their own (first person) perspective or the (third person) perspective of their mothers in response to situations involving social emotions or to neutral situations. (...) These results support our prediction that the frontopolar, the somatosensory cortex, and the right inferior parietal lobe are crucial in the process of self/ other distinction. In addition, this study provides important building blocks in our understanding of social emotion processing and human empathy.
    1. Talk And Interaction Among Children, Annual Review of Anthropology Next Article Bookmark and Share

      Excerpt: According to recent interpretive approaches to the study of children's socialization, meaning creation is an active process by which children playfully transform and actively resist cultural categories, and where language is viewed as social action that helps shape reality (...). Four ways in which children's peer talk establishes and maintains peer culture are considered: (a) how children elaborate games and codes (and ritualize the basis of inclusion in the peer group) through peer talk, (b) how conflict talk functions to elaborate peer culture, (c) how identities as peer group phenomena are talked into being through peer talk, and (d) how adult culture is resisted through peer talk.
  9. Novel Mating Strategy: Males Pirate And Fertilize Egg Clutches, ScienceDaily Next Article Bookmark and Share

    Excerpts: (...) The European common frog, Rana temporaria, has long been thought to have a straightforward breeding strategy - one lucky male grabs the female and fertilizes her eggs as soon as she releases them into the water. (...) so many males are vying for fatherhood that they pirate the egg clutches after they're laid. Grasping them as they would a female, they release sperm in the floating clutches, often successfully fertilizing the eggs left unfertilized after the initial encounter. (...) "Because of a population excess of males, the males found a system to reproduce without the female."

  10. Circadian Rhythms In Microorganisms: New Complexities, Annual Review of Microbiology Next Article Bookmark and Share

    Excerpt: Recent advances in understanding circadian (daily) rhythms in the genera Neurospora, Gonyaulax, and Synechococcus are reviewed and new complexities in their circadian systems are described. The previous model, consisting of a unidirectional flow of information from input to oscillator to output, has now expanded to include multiple input pathways, multiple oscillators, multiple outputs; and feedback from oscillator to input and output to oscillator.(...)

    Mathematical models of the Neurospora system are also discussed

    1. Transmission Rates And Adaptive Evolution Of Pathogens In Plant Populations, Alphagalileo & Proc. B Next Article Bookmark and Share

      Abstract: In order to design successful strategies to control plant diseases, it is important to understand the effects of agricultural practices on the evolution and diversity of pathogens. To achieve this we developed and analysed a mathematical model for evolution of a pathogen exposed to two host plants. We assumed that an increase in the ability to transmit infection on one host invokes a fitness cost that decreases the ability to transmit infection of the other. Our results show that the nature of this relationship has a strong impact on the evolution of diversity within pathogens and the range of hosts they can infect.

      Excerpts: One of the most comprehensive studies of the forces that have shaped patterns of human genetic variation has found strong evidence for the action of natural selection, which may help explain why certain people are at risk for a variety of conditions and others are not. (...) For the paper, researchers studied the molecular evolution of 132 genes by comprehensively resequencing them in 24 African-Americans and 23 European-Americans. The results showed strong evidence for natural selection at eight genes in the European-American population, likely explained by the different environmental conditions people encountered as they moved into Europe sometime between 25,000 to 50,000 years ago.

      Excerpt: To what extent do photosynthetic organisms use quantum mechanics to optimize the capture and distribution of light? Answers are emerging from the examination of energy transfer at the submolecular scale. (...)

      Plants use solar antennae to capture incident photons and transmit the excitation energy to reaction centres, where it is used to initiate the primary electron transfer reactions of photosynthesis. These antennae are one of nature's supreme examples of nanoscale engineering, and are constructed from specialized light-harvesting complexes (...). Photon collection involves up to several hundred light-absorbing molecules, (...).

  11. Enter Transfer RNA, Nature Next Article Bookmark and Share

    Excerpt: By the 1950s, scientists generally assumed that converting genetic information into the substance of life was a matter of translation. A DNA sequence, made from a combination of four kinds of nucleotides, was translated into a protein sequence, which was made from a combination of twenty kinds of amino acids. But how did this translation occur, and what machinery was involved? (...)

    How the answers were found includes an unexpected subplot that involves the joining of two groups of scientists with very different backgrounds and interests - biochemists and molecular biologists.

      Excerpts: The most familiar role for RNA is as a relatively passive intermediary in the translation of information from genes into proteins. But other functions for this versatile molecule have been emerging. This Insight explores the surprising recent discovery that RNA can actively regulate gene expression.

      RNA interference or RNAi is a remarkable process whereby small noncoding RNAs silence specific genes.(...)

      Small RNAs termed microRNAs regulate gene expression in organisms ranging from nematode to man.

      Excerpts: In a remarkably short time since its discovery in model organisms, the RNAi pathway has emerged as a powerful tool for the study of gene function in mammals. (...) it seems likely that RNAi will find a place (...) in the treatment of diseases, although it is unclear how long we will have to wait to witness the first RNAi-based drug. The big question is whether RNAi can revolutionize the treatment of human disease in the same way that it has revolutionized basic research into gene function.

      Go deep. A bit of wasted energy may help a quarterback's arm achieve the optimal angle and speed for long passes.
      Credit: Corbis
      In throwing and other physical activities, the first step forward is often a step back. For example, to jump straight up, a person first crouches toward the ground. The body briefly continues to move downward even after the muscles in the legs and torso begin to pull it upward, and when moving one way and pulling the other, the body does mechanical work against itself and wastes energy. Similarly, in throwing, the forearm momentarily moves backward even as the upper arm pulls it forward, again squandering energy. Biomechanicists have proposed various explanations for such "countermotion.

    Excerpt:
    Quantum Jostling. Atoms of a confined, ordinary gas don't collide much after the gas expands. However, when a trapped gas of strongly interacting, fermionic atoms is released, the atoms themselves effectively grow in size. Sustained jostling and pressure among those ballooning atoms can cause telltale, lopsided gas expansion.

    Excerpts: The Pentagon's chief weapons evaluator has calculated that the system may be capable of hitting its targets only about 20 percent of the time. The Missile Defense Agency (MDA), which is responsible for developing the system, offers estimates of greater than 80 percent, according to several officials familiar with the classified figures.

    The missile defense system, a top Bush administration priority, is designed to send interceptors into space to knock down enemy warheads.

    The first two interceptors have already been lowered into silos (...).
    Editor's Note: The old Star Wars system of the 80s was announced to shoot down 80 percent of the incoming missiles. One could ask if lowering that probability to 20 percent has any defense value considering the costs and potential scenarios where the system would be used. So far only North Korea recently has the nuclear weapons and missile capabilities.

  16. Middle Miocene Southern Ocean Cooling and Antarctic Cryosphere Expansion, Science Next Article Bookmark and Share

    Excerpt: The large, permanent ice sheets that presently occupy Antarctica began to form around 14 million years ago, when Earth entered a phase of global cooling. However, the climate processes that produced these changes, as well as the temporal relation between ice sheet growth and cooling, have remained obscure. Shevenell et al. (p. 1766) analyzed Mg/Ca ratios (...) from Southern Hemisphere marine sediments with ages between 15 and 13.2 million years. Deep-ocean cooling began roughly 60,000 years before ice sheet growth, and both of these processes happened during a period of atmospheric CO2 increase. These findings suggest that factors other than radiative forcing, such as ocean heat transport, were key elements of this climate transition.

      Excerpt: Oil ministers are meeting to consider raising the formal output ceiling as crude prices remain stubbornly high despite OPEC's persistent efforts to lower them.

      (...) OPEC's actions have had some limited success. Prices have remained well above the $22 to $28 a barrel target range (...) even as most of the group's members are producing as much as they can. (...)

      Mr. Naimi has in recent months called for oil prices of about $25 a barrel. Higher prices could hurt OPEC in the long run by curbing demand for crude oil.

  17. Ready or Not (and Maybe Not), Electronic Voting Goes National, NY Times Next Article Bookmark and Share

    Excerpt: In what may turn out to be one of the most scrutinized general elections in the country's history, nearly one-third of the more than 150 million registered voters in the United States will be asked to cast their ballots on machines whose accuracy and security against fraud have yet to be tested on such a grand scale.

    Because of the uncertainties, experts say there is potential for post-election challenges in any precincts where the machines may malfunction, or where the margin of victory is thin.
    Editor's Note: This almost sounds like the elections could be decided by smart hackers who make sure the machine appear to function normally and who produce clear victories for the party of their choice.

      Countries certified as "majors" by Washington can attract US sanctions, but the White House said such penalties were unlikely this year.

      The UN released figures earlier this year saying three-quarters of the world's opium poppy was now grown in Afghanistan.

      Hamid Karzai has warned that drug-trafficking and production is helping terrorism, and the Central Bank governor reportedly said earlier this week it accounted for a third of the country's economy.

      The US report noted the "good faith efforts" by the Afghan government to tackle the problem.
      Editor's Note: It might be interesting to do a comparative quantitative estimate of the effect on the war on terrorism before and after the wars in Afghanistan and Iraq.

    4. Iraq War Illegal, Says Annan, BBC News Next Article Bookmark and Share

      Excerpt: The United Nations Secretary-General Kofi Annan has told the BBC the US-led invasion of Iraq was an illegal act that contravened the UN charter.

      He said the decision to take action in Iraq should have been made by the Security Council, not unilaterally.

      The UK government responded by saying the attorney-general made the "legal basis... clear at the time".(...)

      He has said from the beginning the invasion did not conform with the UN charter - phrasing that was seen as a diplomatic way of saying the war was illegal.

    5. Powell Rebukes Annan On Iraq, Washington Post Next Article Bookmark and Share

      Excerpt: Secretary of State Colin L. Powell yesterday expressed strong disapproval of U.N. Secretary-General Kofi Annan's description of the U.S.-led war in Iraq as illegal, saying the comment was "not a very useful statement to make at this point."

      "What does it gain anyone? We should all be gathering around the idea of helping the Iraqis, not getting into these kinds of side issues," Mr. Powell said (...).

      [Mr Powell] lamented the unwillingness of many in the Muslim and Arab world to take on Islamic extremists in their midst.
      Editor's Note: The wide perception of a rule of law has been mentioned as one of the important parameters that determine the recruitment rate of terrorist organizations. Legality of a super-power to attack and occupy a sovereign nation seems to be a central issue for that perception.

    6. Saudis Take a Small Dose of Democracy, Washington Post Next Article Bookmark and Share

      Excerpt: For the first time in 41 years, it is allowing elections, local ones, that will fill half the seats on 178 municipal councils.

      The ruling family's goal, political analysts and diplomats here say, is to determine whether a more open government might help defuse a rising armed threat by Muslim militants in the kingdom or merely inspire reform advocates to push harder against the princes' long hold on power. (...)

      In a country that takes even its name from the ruling family, few institutions are more foreign than electoral politics.
