  1. Einstein's Sphere Of Influence, The New Mexican Bookmark and Share

    Excerpts: Constantino Tsallis, a visiting researcher from Brazil, works in the field of statistical mechanics. Among the topics he studies are the motions of atoms, the building blocks of matter in the universe. Tsallis references Einstein's work on proving the existence of atoms as laying a foundation for his work. (...)

    "Scientific creativity has a lot to do with an aesthetic feeling of beauty, " Tsallis said. "If an equation has some great beauty, you can almost (assume) that it's correct. Because when it's not correct, it shows some ugliness."


  2. Nanorobotics Control Design: A Collective Behavior Approach For Medicine, NanoBioscience, IEEE Bookmark and Share

    Excerpt: The authors present a new approach using genetic algorithms, neural networks, and nanorobotics concepts applied to the problem of control design for nanoassembly automation and its application in medicine. As a practical approach to validate the proposed design, we have elaborated and simulated a virtual environment focused on control automation for nanorobotics teams that exhibit collective behavior. This collective behavior is a suitable way to perform a large range of tasks and positional assembly manipulation in a complex three-dimensional workspace. (...)

    1. Directed Discovery of Novel Drug Cocktails, SFI Working Papers Bookmark and Share

      Excerpt: Combinations of drugs can result in effective treatments for certain diseases like HIV/AIDS. Unfortunately, our ability to discover such combinations is quite limited, as drugs often interact in highly nonlinear ways and thus it is difficult to predict a priori which cocktails are likely to be effective. Moreover, the brute-force approach of screening all possible combinations fails due to the combinatorial explosion of possible cocktails, even when we consider modest numbers of candidate drugs. As an alternative, here we use a nonlinear search algorithm designed to direct the discovery of novel, effective drug cocktails. (...)

    2. Scar Prevention: The Healing Touch, Nature Bookmark and Share

      Excerpts: Wound an embryo and it heals perfectly, with no scars. Can we teach adult wounds the same trick, (...).

      There are striking similarities between the mechanisms embryos use to heal wounds and those they use to knit their body parts together during normal development. (...)

      A fruitfly embryo closing a wound rapidly assembles a cable of the protein actin in the 'skin' cells at the wound's edges. Contraction of this cable seems to pull the edges together much as a drawstring pulls a bag shut.


  3. Now You See It, Now You Don't: 'Change Blindness' Isn't Magic, ScienceDaily Bookmark and Share

    Excerpts: A team of scientists (...) has discovered why we often miss major changes in our surroundings - such as a traffic light turning green when we're listening to the radio. Our inability to notice large changes in a visual scene is a phenomenon often exploited by magicians - (...) part of the brain that is so often deceived. (...) called the parietal cortex, the area responsible for concentration, is also critical to our ability to detect changes. The exact critical spot lies just a few centimetres above and behind the right ear - the area many people scratch when concentrating. (...)

    1. Science Plumbs Placebo Effect, Christian Science Monitor Bookmark and Share

      Excerpts: New research counters the idea that the effect of fake medicine is 'all in the mind.' When an inert placebo acts like a drug, is it just a psychological illusion? Or is it a real biological effect? Research reported last week suggests that it's both. The mere belief that they had received a pain killer was enough to release the brain's natural painkilling endorphins in the patients tested, scientists say.

      This opens a new line of research into the placebo puzzle. The effect has been demonstrated often enough to show that some patients appear to benefit from such belief. But there hasn't been enough evidence to convince skeptics that anything more than the so-called power of suggestion is at work. That's changing. "The findings of this study are counter to the common thought that the placebo effect is purely psychological due to suggestion and that it does not represent a real physical change." says University of Michigan neuroscientist Jon-Kar Zubieta. He is principal author of the study published Aug. 24 in The Journal of Neuroscience.


    2. Neuroscience: Finding The Missing Fundamental, Nature Bookmark and Share

      Excerpts: The whole orchestra tunes up to an A note from the oboe - but how do our brains tell that all the different sounds are the same pitch? The discovery of pitch-sensitive neurons provides some clues.

      (...) how do we effortlessly recognize the same melody played by different instruments even though the acoustical structure of the sound reaching our ears varies with the instrument? (...) neurons that figure out what the pitch of a sound is (...), giving hints to how we come to perceive pitch as a unified entity.


  4. Left Behind, Way Behind, NY Times Bookmark and Share

    Excerpts: The report, titled "Getting Smarter, Becoming Fairer," restates a point that by now should be clear to most thoughtful Americans: too many American kids are ill equipped educationally to compete successfully in an ever-more competitive global environment.

    Cartoonish characters like Snoop Dogg and Paris Hilton may be good for a laugh, but they're useless as role models. It's the kids who are logging long hours in the college labs, libraries and lecture halls who will most easily remain afloat in the tremendous waves of competition (...).


  5. Prehistoric Sturdy Shoe Fad Discovered, Discovery News Bookmark and Share

    Excerpts:
    Picture: Courtesy of Erik Trinkaus/Czech Academy of Sciences |
    Toes Tell the Tale
    This foot is from the skeleton of an older man who died about 26,000 years ago. It shows the less strongly built smaller toes of these Upper Paleolithic people, compared with earlier Middle Paleolithic modern humans and Neanderthals.
    Trinkaus told Discovery News that "shoes reduce the mechanical stress of the lesser toes," so the four little toes do not have to do much work. He observed less substantial little-toe bones in the later skeleton samples. (...)

    "All people living in very cold climates had to wear some kind of thermal protection on their feet, including Neanderthals and their predecessors," (...). "(Supportive footwear) was part of a major explosion in human technology and cultural complexity, especially after 30,000 years ago."


  6. Coffee Top Antioxidant Source For Americans, Reuters Bookmark and Share

    Excerpts: Europeans have red wine, Asians have green tea but Americans have their own source of antioxidants -- coffee, researchers reported on Sunday.

    Americans drink plenty of coffee, which is high in antioxidants, compounds such as vitamins that fight damage to cells and to DNA, the study found.

    But Americans are not eating enough fruits and vegetables, the sources of antioxidants as well as fiber and other nutrients that dietitians, scientists and doctors recommend, said Joe Vinson of the University of Scranton in Pennsylvania.


  7. A School-Oriented, Age-Structured Epidemic Model, SIAM J. Appl. Math. Bookmark and Share

    Excerpts: A model of childhood epidemics focusing on the impact of the school-year is presented. At the onset of the epidemic season, a new cohort of susceptible students enter the school, all other age-classes advance one year, while the oldest age-group leaves the mixing pool. If the susceptible pool is sufficiently large at the onset of the season, an epidemic will arise (...). The system is expressed in terms of a discrete dynamical system giving the changes in the age-dependent immunity structure on a year-to-year basis. (...) If disease transmission is age-dependent, more complicated dynamics may occur, including multiple stable states and chaos.

    1. Substance Use: Individual Behavior, Social Interaction, Markets And Politics, JAI Press Bookmark and Share

      Excerpts: The economics of substance use and abuse deals with the consumption of goods that share two properties. First, they are addictive in the sense that an increase in past consumption of the good leads to an increase in current consumption. Second, their consumption harms the consumer and others. This second property makes them of interest from policy, legal, and public health perspectives. (...) the presence of many unresolved issues motivate this volume. (...) The aim of the volume to cover issues pertaining to individual behavior, social interactions, markets, and politics makes this all the more necessary. (...)

  8. More Animals Join The Learning Circle, NewScientist.com news service Bookmark and Share

    Excerpts: Killer whales and chimpanzees both pass on "traditions" to other members of their group, according to two separate studies of feeding behaviour. The findings add to evidence that cultural learning is widespread among animals.

    One study involved killer whales at Marineland in Niagara Falls in Ontario, Canada. An inventive male devised a brand new way to catch birds, and passed the strategy on to his tank-mates. The 4-year-old orca lures gulls into his tank by spitting regurgitated fish onto the water's surface.


    1. Primate Communication Linked To Social Bonding, NewScientist.com news service Bookmark and Share

      Excerpts: Communication evolved hand-in-hand with social bonding, suggests a new study of non-human primates, which probes the origins of language.

      ¡§The work tells us that communication is right there at the base of social behaviour and that having a larger vocal repertoire allows you to have a more complex social set up,¡¨ says Karen McComb, at the University of Sussex, UK, who carried out the work.


    2. Chimps Show Sign of Culture, News@Nature Bookmark and Share

      Excerpt: Researchers have found that a group of chimpanzees will stick to the same method used by their peers, even if they stumble across a different way of using a tool by themselves. That shows that chimps follow a cultural norm that is socially learned and maintained, the researchers say - proof, perhaps, that chimpanzees really do have culture.

    3. Copycat Chimps Are Cultural Conformists, New Scientist Bookmark and Share

      Excerpts: Humans are not the only conformists in the animal kingdom. New research shows that chimpanzees also tend to imitate their peers, suggesting that the human penchant for follow-the-leader may be more deeply rooted than thought.

      Chimpanzees have behavioural traditions that vary between groups in the wild but, so far, direct experimental evidence of how these traditions are spread and maintained has been lacking. So Andrew Whiten of St Andrews University, UK, led a team that sought to show a chimpanzee proclivity for cultural conformity in a population of captive animals.


  9. Water And Life: Seeking The Solution, Nature Bookmark and Share

    Excerpts: Is there any fundamental reason to be fixated on water as the universal elixir of life? (...)

    But is it right to see water as the sole medium for extraterrestrial life?

    Some think not. "Water is a terrible solvent for life," (...).

    Unlike physics, of course, biochemistry adapts to its environment, (...) life on Earth is adapted to water rather than the other way round. "Life on Earth itself is fine-tuned to water - a consequence of it evolving in close association with the medium," (...).


    1. Global Patterns of Predator Diversity in the Open Oceans, Science Bookmark and Share

      Excerpts: The open oceans comprise most of the biosphere, yet patterns and trends of species diversity there are enigmatic. Here, we derive worldwide patterns of tuna and billfish diversity over the past 50 years, revealing distinct subtropical "hotspots" that appeared to hold generally for other predators and zooplankton. Diversity was positively correlated with thermal fronts and dissolved oxygen and a nonlinear function of temperature ( 25¢XC optimum). Diversity declined between 10 and 50% in all oceans, a trend that coincided with increased fishing pressure, superimposed on strong El Ni?o-Southern Oscillation-driven variability across the Pacific.

  10. Exploring Microbial Diversity--A Vast Below, Science Bookmark and Share

    Excerpts: Exploring microbial diversity is becoming more like exploring outer space with soil representing a "final frontier" that harbors a largely unknown microbial universe. There are more than 1016 prokaryotes in a ton of soil compared to a mere 10 11 stars in our galaxy. Astronomers have wisely inferred the population of celestial objects by mathematical inference. Now microbiologists are following suit, adopting a similar strategy to estimate the number of prokaryote taxa in soil. (...) the inferred diversity is staggering--higher than previously thought by almost three orders of magnitude.

    1. Evolution: A Treasure Trove Of Motors, Nature Bookmark and Share

      Excerpts: The myosins are a superfamily of protein motors. Analysis of their sequences in a wide range of organisms reveals an unexpected variety of domains, and provides insights into the nature of the earliest eukaryotes.

      Motor proteins use chemical energy, (...), to generate unidirectional movement along a filamentous track. How a group of proteins acquired and then varied this property to generate a range of movements as evolution proceeded is a fascinating problem in biology. Answers are within reach because of the availability of genome sequences from a diverse cadre of organisms (...).


    2. The Contribution Of Species Richness And Composition To Bacterial Services, Nature Bookmark and Share

      Excerpts: Bacterial communities provide important services. They break down pollutants, municipal waste and ingested food, and they are the primary means by which organic matter is recycled to plants and other autotrophs. (...) Biodiversity influences the way in which ecosystems function, but the form of the relationship between bacterial biodiversity and functioning remains poorly understood. Here we describe a manipulative experiment that measured how biodiversity affects the functioning of communities containing up to 72 bacterial species constructed from a collection of naturally occurring culturable bacteria.

    By fabricating synthetic gecko hairs from different materials, they found that the geckos' adhesive powers came not from chemistry, but from geometry -- the size and shape of the tips of the gecko foot hairs.

    Geckos have very hairy feet. Each gecko foot is covered by half a million setae, tiny hairs 50,000 nanometers long. (...)

    The scientists discovered that an appropriate arrangement of setae and spatulae held the geckos to the wall by means of a type of an intermolecular attraction known as a van der Waals force.

    Excerpts: In the booming world of online poker, anyone can win. Especially with an autoplaying robot ace in the hole. Are you in, human?

    It's late one Wednesday afternoon, and CptPokr is logged on to PartyPoker.com and ready to play. Onscreen, the captain exudes a certain brash charisma - broad shoulders, immaculate brown hair, restless animatronic eyes. He looks like he should be playing synth in Kraftwerk. Instead, he is seated at a virtual table with nine other avatars, wagering on limit Texas hold 'em.


  13. Intel Says Forget Megahertz And Gigahertz, Forbes.com Bookmark and Share

    Excerpts: In the future, how will geeks brag about their computers to friends? Intel Chief Executive Paul Otellini says megahertz and gigahertz is out, and "performance per watt" is in.

    Performance per watt is a way of measuring not just how fast a computer can grind data, but also how much power it uses when doing so. The combined measurement is more relevant to smaller, flexible devices, like notebook computers, portable media players and smart phones.


    1. Key Computer Breakthrough, IST News Bookmark and Share

      Excerpt: Russian scientists have invented a computer keyboard where each key has its own tiny video screen. It means the symbols on the keys can be changed to show different languages or symbols at a stroke. Every single key of the Art.Lebedev Studio's all-purpose Optimus keyboard is a 32 x 32 pixel Organic Light Emitting Diode display. The keyboard will enable users to switch from the Arabic, Cyrillic or Latin alphabet or HTML code in a matter of seconds. But it could also be programmed for the use of any given software, like photo manipulation software, computer games or music composition programmes. The keyboard will have an aluminium case and polycarbonate keys and is due to be released on the market in 2006.

  14. A Generative Model for Feedback Networks, SFI Working Papers Bookmark and Share

    Excerpt: We investigate a simple generative model for network formation. The model is designed to describe the growth of networks of kinship, trading, corporate alliances, or autocatalytic chemical reactions, where feedback is an essential element of network growth. The underlying graphs in these situations grow via a competition between cycle formation and node addition. (...)

    1. The Evolution Of Network Topology By Selective Removal, Interface Bookmark and Share

      Excerpts: The topology of large social, technical and biological networks such as the World Wide Web or protein interaction networks has caught considerable attention in the past few (...), and analysis of the structure of such networks revealed that many of them can be classified as broad-tailed, scale-free-like networks, since their vertex connectivities follow approximately a power-law. (...) Here, we propose a new model that can generate broad-tailed networks even in the absence of network growth, by not only adding vertices, but also selectively eliminating vertices with a probability that is inversely related to the sum of their first- and second order connectivity.

  15. Coarse-Graining of Cellular Automata, Emergence, and the Predictability of Complex Systems, arXiv Bookmark and Share

    Excerpts: We study the predictability of emergent phenomena in complex systems. Using nearest neighbor, one-dimensional Cellular Automata (CA) as an example, we show how to construct local coarse-grained descriptions of CA in all classes of Wolfram's classification. The resulting coarse-grained CA that we construct are capable of emulating the large-scale behavior of the original systems without accounting for small-scale details. Several CA that can be coarse-grained by this construction are known to be universal Turing machines; (...). We thus show that because in practice one only seeks coarse-grained information, complex physical systems can be predictable and even decidable at some level of description.(...)

    1. "Colony" Computer To Look For A Theory Of Theories, UC Davis News Bookmark and Share

      Excerpts:
      This graphic shows the results of a circular "computational automaton" -type computer model after 100 cycles. The program begins in the center and moves outward in concentric rings. At each step, each cell in the model decides its state, e.g. one or zero, based on the state of its neighbors. (Jim Crutchfield/UC Davis)
      The machine could be used for experiments in fluid dynamics, weather forecasting, geology or ecology. But Crutchfield is primarily interested in a deeper problem.

      Working at the Santa Fe Institute in New Mexico and now at UC Davis, Crutchfield has developed a new theory of how cellular automata can spontaneously organize into miniature universes with their own unique "physics" -- structures of interacting particles. The ultimate goal is to understand how structure can appear at different levels of the universe, how the levels are related to each other, and how scientists (and computers) can automatically construct theories from data.


  16. Bicycle Dynamics And Control: Adapted Bicycles For Education And Research, Control Systems Magazine Bookmark and Share

    Abstract: In this paper, the dynamics of bicycles is analyzed from the perspective of control. Models of different complexity are presented, starting with simple ones and ending with more realistic models generated from multibody software. Models that capture essential behavior such as self-stabilization as well as models that demonstrate difficulties with rear wheel steering are considered. Experiences using bicycles in control education along with suggestions for fun and thought-provoking experiments with proven student attraction are presented. Finally, bicycles and clinical programs designed for children with disabilities are described.

    1. Robotic Spy-Planes Use Shape-Shifting Wings, New Scientist Bookmark and Share

      Excerpts:
      The tiny surveillance drone mimics the changing wing shape used by seagulls to switch between agile and stable configurations (Image: Kristen Bartlett/University of Florida)
      The articulated wings - with a span of 60 centimetres - were inspired by the way seagulls alter their wing-shape during flight, (...).

      The change in flight performance comes partly from a shift in the aircraft's centre of gravity, says Lind: ¡§With the wing position higher than the centre of gravity it is stable like a pendulum.¡¨ Reversing this - the "W" position - produces low stability, like an inverted pendulum. See a movie of the craft showing off its different in-flight configurations, here (Mpeg format).


  17. Earth's Core Spins Faster Than the Rest of the Planet, NY Times Bookmark and Share

    Excerpts: While the inner core is almost spherical in shape, its composition appears to have a wood-grain-like layering, which could speed or slow seismic waves.

    Scientists believe they understand why the inner core might rotate at a different rate. The flow of rising and falling iron in the liquid outer core generates electric and magnetic fields, which push on the metallic inner core. "The thing is acting like a huge rotor in an electric motor," Dr. Richards said. "Except this one is running a billion amps."


  18. Iraq Charter A 'Recipe For Chaos', BBC News Bookmark and Share

    Excerpts: Parts of the Iraqi draft constitution submitted on Sunday are a "recipe for chaos", Arab League Secretary General Amr Moussa has warned. (...)

    They fear the proposals would lead to the break-up of the country into a Kurdish north and Shia south, depriving the Sunnis of access to the country's oil resources. (...)

    "I do not believe in this division between Shia and Sunni and Muslims and Christians and Arabs and Kurds," he said. "I don't buy this and I find in this a true recipe for chaos and perhaps a catastrophe in Iraq and around it."

    1. Al-Qaeda Trying To Set Up Network In Southern Africa, People's Daily Online, China Bookmark and Share

      Excerpts: Ronald Ronnie Kasrils, intelligence minister of South?Africa, warned on August 29 that Al-Qaeda members are trying to build their network in southern Africa, in order to launch attacks against African ports. According to local reports, Kasrils said at a navy conference in Cape Town that some organizations in Africa claimed they are part of Al-Qaeda or other organizations, and we also found people taking shelter in southern Africa to set up their network. Africa is engaged in offshore oil and gas exploitation, he pointed out, which can easily become targets of criminals and terror groups.

    2. 40,000 Jihadis Threaten Europe: Claim, United Press International Bookmark and Share

      Excerpts: More than 40,000 Islamist activists are already in Britain and Germany, an expert says. Terrorism expert Rolf Tophoven warned in a new study that there are already over 10,000 active al-Qaida activists in Britain and 31,000 more Islamist militants in Germany. (...).

      Tophoven, in his paper "The European Network of Al-Qaida", said a relatively small minority of European Muslims were capable of launching a jihad, or holy war, against their host countries.

      The findings were presented at a three day seminar on "Global Terrorism" in Islamabad organized by Pakistan's Institute of Regional Studies, ANI said.
