  1. The Impact of Political Advertising on Knowledge, Internet Information Seeking, and Candidate Preference, J. Communication Next Article Bookmark and Share

    Excerpts: Previous research has suggested that exposure to political advertising is generally informative and may even reduce information gaps between the most and least aware in society, but does not produce large shifts in candidate preference. Drawing on extant models of opinion change, we predicted that the informational benefits of political ads would vary by level of awareness, such that the most aware would experience the largest gains, especially when they are asked to make inferences about issues not explicitly discussed in the ad. Further, (...) most aware would use information in advertisements as a substitute for other kinds of information seeking, (...).
    1. Social Structure and Opinion Formation, arXiv Next Article Bookmark and Share

      Excerpt: We present a dynamical theory of opinion formation that takes explicitly into account the structure of the social network in which individuals are embedded. The theory predicts the evolution of a set of opinions through the social network and establishes the existence of a martingale property, i.e. that the expected weighted fraction of the population that holds a given opinion is constant in time. Most importantly, this weighted fraction is not either zero or one, but corresponds to a non-trivial distribution of opinions in the long time limit. This co-existence of opinions within a social network is in agreement with the often observed locality effect (...)
    2. Phase Transitions for Rock-Scissors-Paper Game on Different Networks, arXiv Next Article Bookmark and Share

      Abstract: Monte Carlo simulations and dynamical mean-field approximations are performed to study the phase transitions in rock-scissors-paper game on different host networks. These graphs are originated from lattices by introducing quenched and annealed randomness simultaneously. In the resulting phase diagrams three different stationary states are identified for all structures. The comparison of results on different networks suggests that the value of clustering coefficient plays an irrelevant role in the emergence of a global oscillating phase. The critical behavior of phase transitions seems to be universal and can be described by the same exponents.
  2. How Love Evolved From Sex And Gave Birth To Intelligence And Human Nature, J. Bioecon. Next Article Bookmark and Share

    Excerpts: This article argues that emotional attachment drive has shaped the evolution of human intelligence, interpersonal relationships and culture. The first section is about the evolution of social bonds and their role in the rise of intelligence. At the outset, I present evidence that desire for emotional closeness to others is a primary human instinct. Recent discoveries in neurobiology are then incorporated into a summary of the evolution of brain systems that activate emotional attachments (...). The evolution of maternal behavior is discussed as a particularly important event enabling expansion of brain size and complexity (...) leading ultimately to the modern human brain.
    1. From Nosy Neighbors to Cultural Evolution, Science Next Article Bookmark and Share

      Excerpts: Psychologists, economists, and advertising moguls have long known that human decision-making is strongly influenced by the behavior of others. A rapidly accumulating body of evidence suggests that the same is true in animals. Individuals can use information arising from cues inadvertently produced by the behavior of other individuals with similar requirements. Many of these cues provide public information about the quality of alternatives. The use of public information is taxonomically widespread and can enhance fitness. Public information can lead to cultural evolution, which we suggest may then affect biological evolution.
  3. Here Comes The MP3 Revolution, Contra Costa Times Next Article Bookmark and Share

    Excerpts: While the record companies battled Napster and so-called music piracy in court, tech companies saw a different future in other statistics: namely, that at least 33 percent of obtainable music will be delivered digitally within five years. Voila -- along comes the MP3 player and the current benchmark, the iPod, bypassing CD burning and eliminating the CD. Users instead download music onto a handheld computer that, essentially, acts like a mini jukebox without the physical records.

    Only this jukebox costs about $400 and holds up to 15,000 songs, (...).

  4. Traffic Forecast In Large Scale Freeway Networks, Int. J. Bifur. & Chaos Next Article Bookmark and Share

    Excerpts: Traffic flow in large and complex freeway networks is a highly nonlinear phenomenon, which makes traffic forecast a difficult task. In this article an approach to traffic forecast is presented, which uses a micro-simulator for traffic flow combined with current and historical traffic data. The micro-simulator and locally measured current traffic data are used to reconstruct the current network-wide traffic state. (...) The micro-simulator uses an advanced cellular-automaton model for traffic flow, and the data are supplied from more than 4,000 locally installed loop-detectors, which deliver information on the (local) traffic state online minute by minute.

    1. The Value Of Snowfall To Skiers And Boarders, Env. & Resource Econ. Next Article Bookmark and Share

      Abstract: An interesting winter sport phenomenon in recent years has been the growth of snowboarding. Snowboarding has outpaced skiing at many resorts and has become the snow riding activity of choice for many young people. This study develops an empirical demand model for winter sport trips amongst college students from both camps and estimates economic welfare associated with the two different activities. The results show that both trip demand and surplus values are strongly affected by snow conditions. These effects are distinctly different for the two consumer groups.

  5. Technological Networks and the Spread of Computer Viruses, arXiv Next Article Bookmark and Share

    Abstract: Computer infections such as viruses and worms spread over networks of contacts between computers, with different types of networks being exploited by different types of infections. Here we analyze the structures of several of these networks, exploring their implications for modes of spread and the control of infection. We argue that vaccination strategies that focus on a limited number of network nodes, whether targeted or randomly chosen, are in many cases unlikely to be effective. An alternative dynamic mechanism for the control of contagion, called throttling, is introduced and argued to be effective under a range of conditions.
  6. Biodiversity: A Tragedy With Many Players, Nature Next Article Bookmark and Share

    Excerpts: Peter Ng is a man with a mission: to catalogue the huge diversity of life dwelling in habitats long dismissed as uninteresting. (...)

    The peat swamps, in particular, are being drained as fast as he can sample them, sometimes for urban or agricultural development, at other times - in a bitter irony - under the guise of 'environmental improvement'.

    The rich faunas found in such neglected habitats underline a growing realization that conservation biologists really know very little about our planet's biodiversity (...).

    1. Population Variation In Lateralised Eye Use, Alphagalileo & Biol. Lett. Next Article Bookmark and Share

      Excerpts: It is well known that humans, and virtually all other vertebrates, use one side of their brain for some tasks and the other side for other tasks (lateralisation). Evolutionary biologists have struggled to explain why lateralisation initially arose and why it persists. (...) shown that the pattern of lateralisation within a species varies depending on the level of predation pressure present in the environment, suggesting that various ecological pressures shape the relative costs and benefits associated with the development of lateralised brains. Their discovery has considerable implications for the understanding of the evolution of brain lateralization in all animals including humans.

      Excerpts: A look at the emerging science of epigenetics: inherited information that isn't in the form of genes.
  7. Human Intelligence Determined By Volume And Location Of Gray Matter Tissue In Brain, Today@UCI Next Article Bookmark and Share

    Excerpts:
    Areas in brain activated by IQ testing
    General human intelligence appears to be based on the volume of gray matter tissue in certain regions of the brain, (...).

    (...) because these regions related to intelligence are located throughout the brain, a single "intelligence center," such as the frontal lobe, is unlikely. (...)

    Previous research had shown that larger brains are weakly related to higher IQ, but this study is the first to demonstrate that gray matter in specific regions in the brain is more related to IQ than is overall size. Multiple brain areas are related to IQ,

    1. Epileptic Neurons Go Wireless, Science Next Article Bookmark and Share

      Excerpts: The idea that "neurons that fire together, wire together" is well established in developmental neuroscience. (...) neurons that fire action potentials at the same time are more likely to develop synaptic connections with each other. In epilepsy, this process is taken to an unhealthy extreme: Neurons that fire together during seizures wire together through a process called axonal sprouting. (...) some of the positive feedback that underlies the epileptic condition may be formed "wirelessly"--that is, using a mechanism that does not involve growth of new axons or synaptic connections.
  8. Children Think Before They Speak, Nature Next Article Bookmark and Share

    Excerpts: A linguistic contrast between English and Korean provides a telling test of different ideas about whether thought precedes the acquisition of language, or whether certain concepts are language-specific.

    For Augustine, thought precedes language: language is a tool with which to express one's ideas and to understand the ideas of others. (...) Many scholars would instead endorse the theory of linguistic relativity, and maintain that learning a language has a profound influence on a child's mental life. If so, then speakers of different languages might think in very different ways.

    1. Conceptual Precursors To Language, Nature Next Article Bookmark and Share

      Excerpts: Because human languages vary in sound and meaning, children must learn which distinctions their language uses. For speech perception, this learning is selective: (...); however, infants' sensitivity to non-native sound distinctions declines over the course of the first year. Here we ask whether a similar process governs learning of word meanings. We investigated the sensitivity of 5-month-old infants in an English-speaking environment to a conceptual distinction that is marked in Korean but not English; (...). Language learning therefore seems to develop by linking linguistic forms to universal, pre-existing representations of sound and meaning.
    2. Stuttering More Than Talk - Research Shows Brain's Role In Disorder, ScienceDaily Next Article Bookmark and Share

      Excerpts: New research from Purdue University shows that even when people who stutter are not speaking, their brains process language differently. "Traditionally, stuttering is thought of as a problem with how someone speaks, and little attention has been given to the complex interactions between neurological systems that underlie speaking, (...) We have found differences in adults who stutter, compared to those who don't, in how the brain processes information when people are thinking about language but not speaking. For example, there was a significant delay in response time when subjects were given a complex language task. (...)"
  9. Audience Drives Male Songbird Response To Partner's Voice, Nature Next Article Bookmark and Share

    Excerpts: (...), avian communication generally takes place in a network of signallers and receivers, which represents an audience altering individual signalling behaviours. (...). This 'audience effect' provides support for the reality of social awareness in some bird species. However no evidence has yet been found to suggest that birds are able to estimate the characteristics of the social relationships between group-mates. Here we show that the male of (...) the zebra finch (...)-pays attention to the mating status of conspecific pairs, and uses this information to control its behaviour towards its female partner.
    1. Animal Behaviour: A Social Call, Nature Next Article Bookmark and Share

      Excerpts: An indicator of animal intelligence is thought to be the ability to judge relationships between members of the same species. (...)

      (...) female zebra finches can recognize their mate, with whom they form lasting pair bonds, by his 'distance call', (...). But (...) male zebra finches did not recognize their mate through female distance calls. (...)

      One overlooked factor was the context in which these recognition tests were conducted. The birds, normally members of large flocks in the wild or large groups in captivity, had been tested while alone.

    2. Coalition Among Male Fiddler Crabs, Nature Next Article Bookmark and Share

      Excerpts: Seeing off a neighbour's intruder may be easier than negotiating with a larger usurper.

      Until now, no compelling evidence has emerged from studies of animal territoriality to indicate that a resident will strategically help a neighbour to defend its territory against an intruder. We show here that territory-owning Australian fiddler crabs will judiciously assist other crabs in defending their neighbouring territories. This cooperation supports the prediction that it is sometimes less costly to assist a familiar neighbour than to renegotiate boundaries with a new, and possibly stronger, neighbour.

  10. Toward A 0th Law Of Thermodynamics: Order-Creation Complexity Dynamics, J. Bioecon. Next Article Bookmark and Share

    Excerpts: (...) A more recent view is that the most significant dynamics in bio- and econospheres are not variances around equilibria. Instead order is now seen to be due to the interactions of autonomous, heterogeneous agents energized by contextually imposed tensions (...) also calls for a change away from the definition of science rooted in the equilibrium mathematics of Newton's orbital mechanics. This new message from natural science is about rapid-fire dynamics calling for a fast-motion science of order-creation before the equilibria of the 1st Law (...). The possibility of a 0th law - of agents' self-organization toward order creation - is considered. (...)
  11. For Doctored Photos, a New Flavor of Digital Truth Serum, NY Times Next Article Bookmark and Share

    Excerpts: (...) develop software that can automatically figure out which digital pictures are real and which ones are fake.

    "It used to be that you had a photograph, (...) - that was truth," (...) To put some measure of guarantee back in photography."

    (...) The United States military has become increasingly reliant on digital images from drones and satellites to give soldiers a sense of the battlefield. Law enforcement officers routinely use digital cameras to photograph crime scenes. Newspapers and magazines are now dependent on digital photographs that can be easily doctored.

  12. Quantum Change For Nanotubes, nanotechweb Next Article Bookmark and Share

    Excerpts:
    Magnetic magic
    A metallic carbon nanotube can be made into a semiconductor and vice versa when a magnetic field is combined with a little quantum mechanics. (...) in reality it is very difficult to change an insulator into a metal, and vice versa, without, say, applying extreme pressures.

    For nano-scale materials, however, things may be different. (...)

    The magnetic field comes into play via the Aharonov-Bohm effect. This is a quantum phenomenon in which the wavefunction of an electron acquires a phase shift as it follows a trajectory that encloses a magnetic flux (...).

    1. Physics Enters the Twilight Zone, Science Next Article Bookmark and Share

      Excerpts: Parallel universes have launched a thousand bad science-fiction plots. Now mainstream physicists and cosmologists are arguing that they are both useful and, in an infinite cosmos, inevitable (...)

      The basic argument for parallel universes goes like this: Space is infinite. Within any finite volume of space, however, matter and energy can be arranged in only a finite number of ways. So if you carve space into enough same-sized regions, sooner or later they will start repeating themselves.

      Most cosmologists accept the first premise. "(...) an infinite universe is the best bet," (...).

    2. Designing Optimal Micromixers, Science Next Article Bookmark and Share

      Excerpts: Microfluidics is now part of big science and big business. It is a key component of established and developing technologies ranging from lab-on-a-chip biotech devices to inkjet printing. And the field is now bubbling with activity--thousands of papers are published and hundreds of patents are issued each year. A recent collection of papers focuses on one aspect that is common to many of these technologies: mixing. Mixing--or lack thereof--is often a key obstacle to the effective functioning of microfluidic devices in many applications, (...).
  13. Ship-Sinking Monster Waves Revealed By ESA Satellites, ESA News Next Article Bookmark and Share

    Excerpts:
    Giant wave detected in ERS-2 imagette data [The white vertical stripe in the middle of the white horizontal line. The wave is almost 1000m wide. Ed]
    Once dismissed as a nautical myth, freakish ocean waves that rise as tall as ten-storey apartment blocks have been accepted as a leading cause of large ship sinkings. Results from ESA's ERS satellites helped establish the widespread existence of these 'rogue' waves and are now being used to study their origins.

    Severe weather has sunk more than 200 supertankers and container ships exceeding 200 metres in length during the last two decades. Rogue waves are believed to be the major cause in many such cases.

    1. Freak Waves Spotted From Space, BBC News Next Article Bookmark and Share

      Excerpts: Now that their existence is no longer in dispute, it is time to gain a better understanding of these rogues.

      In the next phase of the research, a project called WaveAtlas will use two years' worth of imagettes to create a worldwide atlas of freak wave events.

      The goal is to find out how these strange cataclysmic phenomena may be generated, and which regions of the seas are most at risk.

      (...) "We know some of the reasons for the rogue waves, but we do not know them all."

  14. Virus 'Harnessed to Kill Cancers', BBC NEWS Next Article Bookmark and Share

    Excerpts: Scientists believe they can beat cancer by taking advantage of its natural desire to stay alive. (...) Professor Nick Lemoine and colleagues at Bart's and Queen Mary's School of Medicine and Dentistry have created a modified virus that will do just that. The virus lacks a gene viruses normally use to disguise themselves so they can sneak into the cell unnoticed. Normal cells can recognise they are under attack by the modified virus and commit suicide to prevent it from replicating and infecting other cells. Cancer cells are programmed differently and resist suicide at all costs. This "selfishness" on the cancer's behalf allows the engineered virus to replicate within the cancer cells and spread through the tumour tissue.
  15. How Wounds Heal - Clues From Flies, ScienceDaily Next Article Bookmark and Share

    Excerpts: (...) Tissue damage in humans triggers a well-characterized response marked by rapid blood clotting and a recruitment of epidermal cells to the injury. When you remove a scab, you're also removing some of the newly regenerated tissues growing underneath, thereby interfering with the healing process. Many different cell types and proteins have been linked to the repair process, but the complexity of the mammalian wound response has challenged efforts to determine their individual roles. (...) After stabbing fruitfly larvae with a needle to create a nonfatal puncture wound, the researchers observed the familiar blood clotting and spreading of epidermal cells to promote healing. (...)
  16. Results of Drug Trials Can Mystify Doctors Through Omission, NY Times Next Article Bookmark and Share

    Excerpts: It is a quirk of the F.D.A.'s labeling rules. For a drug's government-approved uses, the label gives doctors important data from clinical tests involving those treatments while spelling out the drug's risks and providing directions for administering it to patients.

    But labels are often allowed to remain silent about a test when the F.D.A. turns down a company's application for approval of a new use or a new patient group - as in the case of Diflucan and ringworm.

    1. Volatile Chemistry: Children and Antidepressants, Science Next Article Bookmark and Share

      Excerpts: First, unpublished studies of Paxil released by GSK suggest that this therapy didn't consistently help depressed children any more than a placebo did. The one published pediatric study of Paxil had shown the opposite.

      The concerns have also prompted regulators to reanalyze unpublished data for other SSRIs. In April, a set of experts commissioned to advise the U.K. government found that unpublished data suggested that four of five SSRIs were unlikely to benefit children--sometimes in contrast to what published data implied.
      Editor's Note: This example illustrates some strong incentive in this industry to selectively publish positive research results.

  17. Science And The War On Drugs: A Hard Habit To Break, Nature Next Article Bookmark and Share

    Excerpts: The US National Institute on Drug Abuse has frequently been accused of bowing to the political agenda of its paymasters. But, (...) its new director swears that the agency is being led by science.

    (...) groups that she declines to identify have pressed her to issue a public statement that marijuana causes brain damage, on the basis of her own imaging studies. Volkow says that she has refused, (...). "I don't want to use science to scare," she says, "I want to use science to educate."

  18. What's the Presidential Tipping Point?, NY Times Next Article Bookmark and Share

    Excerpts: At some point, politicians can step over an amorphous line that separates good or questionable judgment from inexcusably arrogant, outrageous or incompetent behavior," (...) "That shatters trust. Democracy is built on perceptions of trustworthiness. (...)

    When asked by The New York Times and CBS News in June whether Mr. Bush was being completely honest about the war in Iraq, 20 percent of voters said he was mostly lying and 59 percent said he was hiding something. Only 18 percent thought he was telling the entire truth.

    1. The Terror Web, The New Yorker Next Article Bookmark and Share

      Excerpts: Were the Madrid bombings part of a new, far-reaching jihad being plotted on the Internet?

      (...) bin Laden's goals seemed to be motivated mainly by revenge. In 1998, he had decreed that it was the "duty of every Muslim" to kill Americans and their allies. (...)

      The Internet document suggested that a new intelligence was at work, a rationality not seen in Al Qaeda documents before. The Mujahideen Services Center, (...), appeared to operate as a kind of Islamist think tank. (...) "This is political science applied to jihad."

    2. Blow To Saudi As Al-Qaeda Chief Evades Net, Financial Times Next Article Bookmark and Share

      Excerpts: There are also concerns that militants have infiltrated some of the security organisations. This is strongly denied by officials, (...).

      However, some observers suggest the slow pace of social reform is hampering attempts by the security apparatus to adapt to the evolving threat. They argue that social reform is the key to the overall success of the counter-terrorist campaign.

      (...) "It cannot be stressed too firmly that Saudi security is best preserved by broad progress and reform, and not by reforming the Saudi military or intelligence services."

    3. Honorable Commission, Toothless Report, NY Times Next Article Bookmark and Share

      Excerpts: Unfortunately, because of America's low standing in the Islamic world, we are now at a great disadvantage in the battle of ideas. This is primarily because of the unnecessary and counterproductive invasion of Iraq. (...), the commission failed to admit the obvious: we are less capable of defeating the jihadists because of the Iraq war.

      Unanimity has its value, but so do debate and dissent in a democracy facing a crisis. To fully realize the potential of the commission's report, we must see it not as the end of the discussion (...).
