  1. The Great Chain Of Being, Nature Next Article Bookmark and Share

    Excerpts: Over the past 600 million years the Bacteria, Archaea and microbial Eukarya have continued to evolve into brand new niches. As it happens, a few branches of Eukarya - plants and animals - grew freakishly huge bodies. They also created both new substances for bacteria to exploit, such as plant lignins, and new environments for microbes to inhabit, such as feathers and urinary tracts. Indeed, some of the richest and most interesting ecologies on Earth can be found inside the animal gut.

    One of the huge species, Homo sapiens, got remarkably self-important.

  2. Wall Street's Gradual Green Revolution, Nature Next Article Bookmark and Share

    Excerpts: What do atmospheric scientists, investment managers, and some of the world's top engineering firms have in common? An imperative to get moving on climate change (...)

    Kofi Annan, Al Gore and media mogul-turned-philanthropist Ted Turner told some 400 institutional investors and business leaders that the time had come for investment decisions to hinge on how willing a business is to prepare for climate change. (...)

    "We're investing in environmentally cleaner technology because we believe it will increase our revenue, our value and our profits," (...), "not because its trendy or moral."

    1. Trust In Troubled Times, China Quarterly Next Article Bookmark and Share

      Excerpts: Trust in Troubled Times is an important addition to the still relatively small body of literature on banking and finance in Republican China. In this careful and thoughtful study of the development of banking and paper money in Tianjin (...) analyses the rise of modern banks and the growth of social trust in such financial institutions, and examines their relations to the process of state-building. (...) Indeed, one of the main contributions of this book is the tremendous amount of data amassed by the author that illuminates the complexity of the problems associated with banking and finance in the pre-1949 period.

  3. A Network Analysis of Committees in the United States House of Representatives, arXiv Next Article Bookmark and Share

    Abstract: Network theory provides a powerful tool for the representation and analysis of complex systems of interacting agents. Here we investigate the United States House of Representatives network of committees and subcommittees, with committees connected according to ``interlocks'' or common membership. Analysis of this network reveals clearly the strong links between different committees, as well as the intrinsic hierarchical structure within the House as a whole. We show that network theory, combined with the analysis of roll call votes using singular value decomposition, successfully uncovers political and organizational correlations between committees in the House without the need to incorporate other political information.

  4. The Epidemics of Corruption, arXiv Next Article Bookmark and Share

    Abstract: We study corruption as a generalized epidemic process on the graph of social relationships. The main difference to classical epidemic processes is the strong nonlinear dependence of the transmission probability on the local density of corruption and the mean field influence of the overall corruption in the society. Network clustering and the degree-degree correlation play an essential role in corruption dynamics. We discuss phase transitions, the influence of the graph structure and the implications for epidemic control. Structural and dynamical arguments are given why strongly hierarchically organized societies like systems with dictatorial tendency are more vulnerable to corruption than democracies. A similar type of modelling can be applied to other social contagion spreading processes like opinion formation, doping usage, social disorders or innovation dynamics.

    1. Fifteen Minutes of Fame: The Dynamics of Information Access on the Web, arXiv Next Article Bookmark and Share

      Abstract: While current studies on complex networks focus on systems that change relatively slowly in time, the structure of the most visited regions of the Web is altered at the timescale from hours to days. Here we investigate the dynamics of visitation of a major news portal, representing the prototype for such a rapidly evolving network. The nodes of the network can be classified into stable nodes, that form the time independent skeleton of the portal, and news documents. The visitation of the two node classes are markedly different, the skeleton acquiring visits at a constant rate, while a news document's visitation peaking after a few hours. We find that the visitation pattern of a news document decays as a power law, in contrast with the exponential prediction provided by simple models of site visitation. This is rooted in the inhomogeneous nature of the browsing pattern characterizing individual users: the time interval between consecutive visits by the same user to the site follows a power law distribution, in contrast with the exponential expected for Poisson processes. We show that the exponent characterizing the individual user's browsing patterns determines the power-law decay in a document's visitation. Finally, our results document the fleeting quality of news and events: while fifteen minutes of fame is still an exaggeration in the online media, we find that access to most news items significantly decays after 36 hours of posting.

  6. Self-Wiring Supercomputer Is Cool And Compact, New Scientist Next Article Bookmark and Share

    Excerpts: An experimental supercomputer made from hardware that can reconfigure itself to tackle different software problems is being built by researchers in Scotland.

    The system under construction at the Edinburgh Parallel Computing Centre - part of Edinburgh University, UK - will use Field Programmable Gate Array (FPGA) chips instead of conventional microprocessors.

    FPGAs can be reconfigured using software to mimic computer processing equipment that is physically designed to take on specialised task s. In contrast, conventional microprocessors are designed to act as fixed, general purpose processing devices.

    1. Physicists Control The Flip Of Electron Spin, PhysOrg.om Next Article Bookmark and Share

      Excerpts: Today's computers and other technological gizmos operate on electronic charges, but researchers predict that a new generation of smaller, faster, more efficient devices could be developed based on another scientific concept - electronic "spin." The problem, however, is that researchers have found it challenging to control or predict spin - which keeps practical applications out of reach.

  7. Solid-State Light Sources Getting Smart, Science Next Article Bookmark and Share

    Excerpts: More than a century after the introduction of incandescent lighting and half a century after the introduction of fluorescent lighting, solid-state light sources are revolutionizing an increasing number of applications. Whereas the efficiency of conventional incandescent and fluorescent lights is limited by fundamental factors that cannot be overcome, the efficiency of solid-state sources is limited only by human creativity and imagination. The high efficiency of solid-state sources already provides energy savings and environmental benefits in a number of applications.

  8. A Weapon The World Needs, Nature Next Article Bookmark and Share

    Excerpts: Both bottom-up and top-down planning is needed to prevent a global economic disaster. Michael T. Osterholm calls for action at all levels.

    Influenza experts are more worried than ever about the next pandemic. It could be caused by H5N1, the avian flu strain of such concern in Asia; it could even rival the devastation of the 1918 Spanish flu pandemic

    1. Avian Flu Special: Avian Flu: Are We Ready?, Nature Next Article Bookmark and Share

      Excerpts: The stage is set for the emergence of a fresh human influenza pandemic. These occur when a virus to which most people have no immunity, usually an avian strain, acquires the ability to transmit readily from person to person. H5N1 hasn't yet gained that ability - and hopefully, it will not.

      But if it does, the virus could spread across the globe within months. The consequences are difficult to predict. We're unlikely to be as lucky as in 1968, when the relatively mild H3N2 virus killed some 750,000 people worldwide.

    2. Genetic Analyses Suggest Bird Flu Virus Is Evolving, Science Next Article Bookmark and Share

      Excerpts: New genetic analyses of samples from recent human H5N1 avian influenza patients reinforce epidemiological evidence suggesting that new strains of the virus may be emerging in northern Vietnam. But an expert report detailing the genetic analyses, posted on the Web site of the World Health Organization (WHO) last week, cautions that data are too limited to draw firm conclusions. Even so, the report urges heightened surveillance, increased preparedness, and further research, warning that H5N1 poses "a continuing and potentially growing pandemic threat."

  9. Developmental Biology: A Blank Canvas No More, Nature Next Article Bookmark and Share

    Excerpts: Embryonic cells learn their fate early in development. Discovery of a factor that controls the development of one embryonic tissue, the ectoderm, highlights a mechanism that might also influence the growth of cancer cells.

    The enormous diversity of body structures in the animal kingdom is somewhat surprising given the commonality of certain developmental processes. The early stages of embryogenesis in bilaterally symmetrical animals, for example, generally involves the process of gastrulation, when the embryo reorganizes from a simple ball of cells into a multilayered organism with a recognizable body plan.

    1. Infant Categorization Of Faces: Ladies First, Dev. Rev. Next Article Bookmark and Share

      Excerpt: We review and provide empirical evidence to show that infants categorize and process male and female faces differently, with an advantage in processing female faces. To understand this asymmetry in categorization and processing of male and female faces, we evaluate three mechanisms influencing infant categorization of male and female faces: differential experience with female and male faces; early visual preferences for female vs. male faces; and range of physical differences among category exemplars. The paper concludes with a developmental trajectory for infant acquisition of face categories proposed within a framework that reflects current knowledge and theory (...).

  10. Rare Items Often Missed In Visual Searches, Nature Next Article Bookmark and Share

    Excerpts: Errors in spotting key targets soar alarmingly if they appear only infrequently during screening.

    Our society relies on accurate performance in visual screening tasks ¡X for example, to detect knives in luggage or tumours in mammograms. These are visual searches for rare targets. We show here that target rarity leads to disturbingly inaccurate performance in target detection: if observers do not find what they are looking for fairly frequently, they often fail to notice it when it does appear.

  11. One Cause for All Confabulations?, Science Next Article Bookmark and Share

    Excerpts: Even though it is no shame to fabricate stories--and some make a living doing so--the term "confabulation," which means exactly this, has always had a negative connotation. It was toward the end of the 19th century that clinicians first described the curious tendency of certain memory-impaired subjects to make up stories about their recent doings (1). Some patients appeared to believe in their stories; others produced them only when questioned.

  12. A Developmental Switch In Neuronal Differentiation, Public Library of Science Next Article Bookmark and Share

    Excerpts: Building an embryo is like building a house: everything has to be done at the right time and the right place if the plans are to be translated faithfully. On the building site, if the roofer comes along before the bricklayer has finished, the result may be a bungalow instead of a two-story residence. In the embryo, if the neurons, for example, start to make connections prematurely, the resultant animal may lack feeling in its skin. (...) In the embryo, the expression of specific transcription factors (...) at different stages of development and in different places controls the orderly construction of the body. (...)

    1. To A Zebra Finch: How The Brain Cultivates Birdsong, Public Library of Science Next Article Bookmark and Share

      Excerpts: (...) the dulcet tones of songbirds have long inspired poetic explorations of the human spirit. Scientists have more recently found inspiration in songbirds, but it is their behavior and not their song that tickles the scientific imagination. Just as the vocal explorations of toddlers reflect the (no doubt) consequential conversations of their elders, the highly variable chirps and warbles of juvenile songbirds echo the precise melodies of the adult songbird. Through trial and error and random forays into harmolodic dissonance, the young bird patterns his performance after a tutor song (usually performed by dad) until he produces a workable facsimile.

    2. The Neural Basis Of Birdsong, Public Library of Science Next Article Bookmark and Share

      Excerpt: (...) Here, I will review basic discoveries made by studying birdsong that have helped answer more general questions in vertebrate neuroscience. Vocal Learning and the "Song System" Oscine songbirds (e.g., zebra finches, canaries, and white-crowned sparrows) learn their song by imitating those of older members of their own species. This is done by modifying vocal output until the auditory feedback it generates matches a memorized model. In some birds vocal learning gives rise to easily discernible song dialects, which then act as local cultural traditions. In most songbirds mastery of a song model takes many weeks. (...)

  13. Spider Signals: Are Web Decorations Visible To Birds And Bees?, Biol. Lett. Next Article Bookmark and Share

    Excerpts: We are becoming increasingly aware of animal communication outside the range of human sensitivity. Web decorations are silk structures used by orb-web spiders to deceive prey and predators. However, despite the level of interest in these structures, their visibility to prey and predators has never, to our knowledge, been objectively assessed. Here, we (...) show that the decorations of all five tested spider species are visible to honey bees and birds over short and long distances. Furthermore, the discoid decorations of one species may provide some protection against arthropod predators. (...)

      The latest big finding came from neuroeconomists, who study how people make decisions about everything from buying a lottery ticket to deciding whether to avoid sitting next to a creepy guy on the bus. Earlier this month, Stanford University researchers reported that they've pinpointed the parts of the brain that handle two major parts of a choice -- figuring out how nifty something is and then calculating how likely it is that you'll get it.

      Excerpts: After I wrote about research showing that women have less appetite for competition than men do, a number of women wrote to inform me that they're just as competitive as any guy. If the tone of their letters is any indication, I have no doubt they are.

      Nor do researchers doubt that such women exist. As Danica Patrick showed in the Indianapolis 500, some women can successfully compete with men at the highest level. But why aren't there more of them?

  14. Revolutionary Nanotechnology Illuminates Brain Cells At Work, PhysOrg Next Article Bookmark and Share

    Excerpts: Until now it has been impossible to accurately measure the levels of important chemicals in living brain cells in real time and at the level of a single cell. Scientists at the Carnegie Institution's Department of Plant Biology and Stanford University are the first to overcome this obstacle by successfully applying genetic nanotechnology using molecular sensors to view changes in brain chemical levels.

      Excerpts: The magnetic resonance imaging devices that hospitals use to diagnose illnesses provide detailed pictures of the insides of the human body by measuring the unique responses of the atoms and molecules in specific types of tissue to particular sequences of radio waves and magnetic pulses.

      The technology also gives scientists a way to control the spins, or magnetic orientations of atoms; this ability has led to several prototype quantum computers.

  15. Resting Microglial Cells Are Highly Dynamic Surveillants of Brain Parenchyma in Vivo, Science Next Article Bookmark and Share

    Excerpts: Microglial cells represent the immune system of the mammalian brain and therefore are critically involved in various injuries and diseases. Little is known about their role in the healthy brain and their immediate reaction to brain damage. By using in vivo two-photon imaging in neocortex, we found that microglial cells are highly active in their presumed resting state, continually surveying their microenvironment with extremely motile processes and pro- trusions. Furthermore, blood-brain barrier disruption provoked immediate and focal activation of microglia, switching their behavior from patroling to shield- ing of the injured site. Microglia thus are busy and vigilant housekeepers in the adult brain.

      Excerpts: Jupiter's Trojans are asteroids that follow essentially the same orbit as Jupiter, but lead or trail the planet by an angular distance of 60 degrees (co-orbital motion).

    2. Scientists: Chaos Theory Solves Solar System Mysteries, Sci-Tech Today Next Article Bookmark and Share

      Excerpts: American scientists say they have developed a tale of chaos in the early solar system that explains several mysteries about why our cosmic neighborhood turned out the way it did. "We get so many of the answers right," (...)" In a single stroke, he and his colleagues say, the tale answers such questions as:

      What set off an intense asteroid bombardment some 3.9 billion years ago that created huge lava-filled basins now visible on the moon and which may have set back the development of life on Earth?

    Excerpts: To estimate the cause-effect relationship between exposure to firearm violence and subsequent perpetration of serious violence, we applied the analytic method of propensity stratification to longitudinal data on adolescents residing in Chicago, Illinois. Results indicate that exposure to firearm violence approximately doubles the probability that an adolescent will perpetrate serious violence over the subsequent 2 years.

    1. Ending the Gerrymander Wars, NY Times Next Article Bookmark and Share

      Excerpts: Congressional redistricting has become a blood sport. Texas kicked off a new era in 2003 when it redrew its lines for a second time after the 2000 census to give the Republicans five more seats. Now, there could be similar midcensus redistricting in several other states. In these partisan machinations, voters are the losers. The new lines eliminate contested elections, and contribute to the bitterly divisive atmosphere in Washington. A new bill in Congress calls for national standards for drawing Congressional districts. It would vastly improve the functioning of our ailing democracy.
