  1. Complex Systems: Order Out Of Chaos, Nature Next Article Bookmark and Share

    Excerpts: Can the behaviour of complex systems from cells to planetary climates be explained by the idea that they're driven to produce the maximum amount of disorder?

    In the past couple of years, Paltridge's hypothesis of maximum entropy production (MEP) has been given a new theoretical underpinning.(...). Entropy could even explain how linked complex systems interact, which could potentially lend legitimacy to the contentious theory of Gaia - the idea that living things act together to regulate Earth's climate to keep conditions favourable for life.

    1. Complexity of Networks, arXiv Next Article Bookmark and Share

      Excerpt: Network or graph structures are ubiquitous in the study of complex systems. Often, we are interested in complexity trends of these system as it evolves under some dynamic. An example might be looking at the complexity of a food web as species enter an ecosystem via migration or speciation, and leave via extinction. In this paper, a complexity measure of networks is proposed based on the complexity is information content paradigm. (...)

    2. The Structure of Collaborative Tagging Systems, arXiv Next Article Bookmark and Share

      Abstract: Collaborative tagging describes the process by which many users add metadata in the form of keywords to shared content. Recently, collaborative tagging has grown in popularity on the web, on sites that allow users to tag bookmarks, photographs and other content. In this paper we analyze the structure of collaborative tagging systems as well as their dynamical aspects. Specifically, we discovered regularities in user activity, tag frequencies, kinds of tags used, bursts of popularity in bookmarking and a remarkable stability in the relative proportions of tags within a given url. We also present a dynamical model of collaborative tagging that predicts these stable patterns and relates them to imitation and shared knowledge.

  2. Cosmology: Original Questions, Nature Next Article Bookmark and Share

    Excerpts: The lack of a coherent quantum description of gravity has impeded our understanding of the physics that determined how the Universe began. A synthesis of recent ideas may take us a step farther back in time. (...)

    Among the deepest, borderline-philosophical questions in modern physics is that of the origin and formation of the Universe. Earlier attempts to formulate an answer (...) have failed because of obstacles posed by gravity. (...) a 'loop quantum gravitational' model that successfully merges current ideas, and which may enable us to overcome such difficulties.

  3. Daisy Has All The Digital Answers To Life On Earth, The Guardian Next Article Bookmark and Share

    Excerpts: Scientists have unveiled plans to create a digital library of all life on Earth. They say that the Digital Automated Identification System (Daisy), which harnesses the latest advances in artificial intelligence and computer vision, will have an enormous impact on research into biodiversity and evolution.

    Daisy will also give Britain's army of amateur naturalists unprecedented access to the world's taxonomic expertise: send Daisy a camera-phone picture of a plant or animal and, within seconds, you will get detailed information about what you are looking at.

    1. The Illusion Of Invariant Quantities In Life Histories, Science Next Article Bookmark and Share

      Excerpts: Life-history theory attempts to provide evolutionary explanations for variations in the ways in which animal species live their lives. Recent analyses have suggested that the dimensionless ratios of several key life-history parameters are the same for different species, even across distant taxa. However, we show here that previous analyses may have given a false picture and created an illusion of invariants, which do not necessarily exist; essentially, this is because life-history variables have been regressed against themselves. The following question arises from our analysis: How do we identify an invariant?

    2. Is Invariance Across Animal Species Just an Illusion?, Science Next Article Bookmark and Share

      Excerpts: There is obvious variation in the way different animals live their lives--in their life span, in their age and size at maturity, and in their size as full-grown adults, to name a few attributes. But are there fundamental similarities in the life history strategies that different animals use? Charnov (1) argued that there are: He proposed fundamental similarities--"life history invariants"--to be a major explanatory ingredient of life history evolution.

  4. Building A Virtual Microbe, Gene By Gene By Gene, NY Times Next Article Bookmark and Share

    Excerpts: An international team of biologists is trying to reconstruct a living thing inside a computer, down to every last molecule, based on Escherichia coli. A full-blown model of E. coli would be able to swim, eat food, fight off invading viruses, make copies of its DNA, and do many other tasks all at the same time. Scientists could potentiallly...

    1. Researchers Creating Life From Scratch, MSNBC/AP Next Article Bookmark and Share

      Excerpts: 'Synthetic biologists' build with one genetic molecule at a time

      They're called "synthetic biologists" and they boldly claim the ability to make never-before-seen living things, one genetic molecule at a time.

      They're mixing, matching and stacking DNA's chemical components like microscopic Lego blocks in an effort to make biologically based computers, medicines and alternative energy sources. The rapidly expanding field is confounding the taxonomists' centuries-old system of classifying species and raising concerns about the new technology's potential for misuse.

  5. Biological Clocks Coordinately Keep Life On Time, Science Next Article Bookmark and Share

    Excerpts: Eating, sleeping, seasonal migration, cell proliferation--a few examples of the many behaviors and life processes that are driven by biological clocks. These "chronometers" coordinate the passage of time with orchestrated cycles that extend from molecular through cellular and systems levels. Timekeeping is part of the very fabric of life, and the clocks that regulate life processes do so over a broad range of time scales: from millisecond oscillations of neuronal activity to seasonal changes that mark shifts in the relative amount of daylight over the course of a year.

  6. Startup Sees Promise In Virus, Wired Next Article Bookmark and Share

    Excerpts: While the concept of applying viruses and proteins to develop electronics seems like a strange hybrid of organic and inorganic science, it's a methodology that's gaining traction in research labs. It's a logical approach, (...), because it relies on materials readily available in nature.

    "You have all the bugs doing all the work for you," (...). "You don't have to be intelligent yourself to design the organic material."

    Cambrios is one of a handful of private and academic institutions employing viruses to create proteins that can be used in commercial applications.

  7. Bitty Beasts Of Burden: Algae Can Carry Cargo, Science News Next Article Bookmark and Share

    Excerpts:
    On For The Long Haul. Beating its twin flagella, this algal cell lugs a polystyrene bead through water. PNAS
    For thousands of years, people have been coaxing other creatures into doing chores. Now, a team of scientists has microsized the strategy. They've devised a way to make single-cell algae bear loads over distances of several centimeters¡Xa tactic that the researchers say could prove useful in tiny machines.

    Algae and other single-celled organisms power their movements with molecular motors. Scientists have long coveted these motors for use in micromachinery, notes chemist Douglas B. Weibel of Harvard University.

  8. Biodiversity: Turning Up The Heat On Hotspots, Nature Next Article Bookmark and Share

    Excerpts: The variety of life on Earth is in rapid decline, and global spending on nature conservation is inadequate to arrest that decline. Consequently, resources for conservation must be allocated to secure the 'biggest bang for our buck'. (...), scientists have identified biodiversity hotspots, where extraordinary concentrations of biodiversity exist, as defined by one or more metrics: number of species (species richness); (...); and number of rare or threatened species. (...) , we need to determine the seriousness of the threat to biodiversity hotspots from processes such as land-use changes.

  9. Against The Current: An Inter-Oceanic Whale Migration Event, Biol. Lett. Next Article Bookmark and Share

    Excerpts: Humpback whales seasonally migrate long distances between tropical and polar regions. However, inter-oceanic exchange is rare and difficult to document. Using skin biopsy samples (...) and a genetic capture-recapture approach based on microsatellite genotyping, we were able to reveal the first direct genetic evidence of the inter-oceanic migration of a male humpback whale. This exceptional migration to wintering grounds of two different ocean basins questions traditional notions of fidelity to an ocean basin, and demonstrates how the behaviour of highly mobile species may be elucidated from combining genetics with long-term field studies. (...)

    1. Whale Wanders Off The Beaten Path, Nature Next Article Bookmark and Share

      Excerpts: Humpbacks make huge migrations, sometimes swimming more than 8,000 kilometres twice a year. They spend their summers feasting in the polar regions, and their winters breeding in the tropics. Infant whales are thought to learn their route from their mother and tend to stick with it for life. (...)

      (...) one whale that has contributed to this mixing, by wintering in the Indian Ocean near Madagascar in 2000 and then turning up on the other side of Africa in the Atlantic near Gabon in the winter of 2002.

  10. Plants Discriminate Between Self And Non Self, ScienceDaily Next Article Bookmark and Share

    Excerpts: Two peas in a pod may not be so friendly when planted in the ground and even two parts of the same plant, once separated may treat the former conjoined twin as an alien enemy," according to a Penn State researcher. "We were looking at how plants determine who is a competitor when competing with other roots for limited resources (...). There is no reason for roots to fight if they belong to the same plant." (...) The mechanism for this self/non-self discrimination could be based on either individually specific chemical recognition -- such as that known from plant reproductive systems (...).

  11. Causes Of Exotic Bird Establishment Across Oceanic Islands, Proc. Biol. Sc. Next Article Bookmark and Share

    Excerpts: The probability that exotic species will successfully establish viable populations varies between regions, for reasons that are currently unknown. Here, we use data for exotic bird introductions to 41 oceanic islands and archipelagos around the globe to test five hypotheses for this variation: the effects of introduction effort, competition, predation, human disturbance and habitat diversity (island biogeography). Our analyses demonstrate the primary importance of introduction effort for avian establishment success across regions, in concordance with previous analyses within regions. However, they also reveal a strong negative interaction across regions between establishment success and predation; (...).

  12. Learning Only When Necessary: Better Memories Of Correlated Patterns In Networks, Neural Computation Next Article Bookmark and Share

    Excerpts: Learning in a neuronal network is often thought of as a linear superposition of synaptic modifications induced by individual stimuli. However, since biological synapses are naturally bounded, a linear superposition would cause fast forgetting of previously acquired memories. Here we show that this forgetting can be avoided by introducing additional constraints on the synaptic and neural dynamics. We consider Hebbian plasticity of excitatory synapses. A synapse is modified only if the postsynaptic response does not match the desired output. With this learning rule, the original memory performances with unbounded weights are regained, (...).

    1. Probing Question: Why Do We Forget?, Research/Penn State Next Article Bookmark and Share

      Excerpts: "I think we should cut our brains some slack," said Dawn Blasko, grinning. "Our brains do an enormous amount of processing. In fact, they work like very effective computers, so effective that we only notice the few things that we forget. We never give our brains credit for the vast amount of material that we do, in fact, remember."

      That said, it's still frustrating when we lose track of the car keys for the umpteenth time, or forget the name of a favorite restaurant. So, what accounts for these run-of-the-mill lapses?

    2. Extensive Piano Practicing Has Regionally Specific Effects On White Matter Development, Nature Neuroscience Next Article Bookmark and Share

      Excerpts: Using diffusion tensor imaging, we investigated effects of piano practicing in childhood, adolescence and adulthood on white matter, and found positive correlations between practicing and fiber tract organization in different regions for each age period. For childhood, practicing correlations were extensive and included the pyramidal tract, which was more structured in pianists than in non-musicians. Long-term training within critical developmental periods may thus induce regionally specific plasticity in myelinating tracts.

      (...)we tested if a fiber tract was susceptible to training-induced plasticity during the period when it was still under maturation.

    3. White Matter Matters In Reading Performance, ScienceDaily Next Article Bookmark and Share

      Excerpts: Recent research (...) has found a correlation between the white matter structure of children's brains and reading performance, suggesting that reading difficulties in children may have a neurological origin. The research, (...) used an advanced magnetic resonance imaging (MRI) technique known as diffusion-tensor MRI to determine which brain structures are correlated with reading ability. (...) "All of these complex cognitive tasks involve multiple areas of the brain. A common way of looking at the brain for cognitive tasks is a technique known as functional MRI, (...) There are these structural signatures in the brain that relate to how well a person can read." (...)

    Excerpts:
    Understanding how neurons work could help with medical treatment ]
    The quest to simulate the mammalian brain on the world's most powerful supercomputer is neuroscience's most ambitious project yet. David Reid went to Lausanne in Switzerland to find out how the line is being blurred between man and machine.

    Inside your head nestles a forest of millions of neurons which weave together to make your thoughts.

    Man has long wanted to discover the secrets of the brain, and has done so with varying degrees of success.

    Excerpts:
    Fighting Heart Failure. Following an operation that constrains blood flow, the hearts of mice grew from normal size (top left) to dangerously large after 3 weeks (top center) and 9 weeks (top right). Mice treated with Viagra's active ingredient (bottom row) experienced no change in heart size after the surgery. Takimoto et al./Nature Medicine
    The test for the boys and girls was simple: to cover as much ground as they could in 6 minutes. But these children, ages 5 to 18, had pulmonary hypertension¡Xhigh blood pressure in their lungs from constricted blood vessels. Such kids "don't have a lot of energy," explains pediatric cardiologist Tilman Humpl. "They can't exercise at all. They may not be able to walk up from the basement to the first floor."

  15. Free Wi-Fi? Get Ready For Googlenet., Business 2.0 Next Article Bookmark and Share

    Excerpts: What if Google (GOOG) wanted to give Wi-Fi access to everyone in America? And what if it had technology capable of targeting advertising to a user's precise location? The gatekeeper of the world's information could become one of the globe's biggest Internet providers and one of its most powerful ad sellers, basically supplanting telecoms in one fell swoop. Sounds crazy, but how might Google go about it?

    First it would build a national broadband network -- let's call it the GoogleNet - (...) Google is already building such a network, (...).

  16. Playing Violent Video Games Can Heighten Aggression, Medical News Today Next Article Bookmark and Share

    Excerpts: Furthermore, violent video game players "tend to imitate the moves that they just 'acted out' in the game they played," said Dr. Kieffer. For example, children who played violent karate games duplicated this type of behavior while playing with friends. These findings demonstrate the possible dangers associated with playing this type of video game over and over again.

    (...) Boys may play more of these types of video games, said Kieffer, because women are portrayed in subordinate roles and the girls may find less incentive to play.

    1. Kids Get Aggressive After Video Games, Psychological Association Calls For Less Violence In Games, Nature News Next Article Bookmark and Share

      Excerpts: The American Psychological Association (APA) has adopted a resolution to reduce violence in children's interactive media. This follows an in-depth review confirming that violent video games can make kids aggressive in the short-term, they say. The long-term effects are still unknown.

      To clarify where the field stands, Kevin Kieffer and Jessica Nicoll (...), conducted an extensive review of 17 studies conducted over 20 years. (...).

      According to their review, there's a strong link between these games and how children and adolescents behave - at least in the short term.

  17. Index Aims For Fair Ranking Of Scientists - 'H-Index' Sums Up Publication Record., Nature Next Article Bookmark and Share

    Excerpts: The h-index is the highest number of papers a scientist has that have each received at least that number of citations. Thus, someone with an h-index of 50 has written 50 papers that have each had at least 50 citations. This, (...), is fairer than alternative measures based on publication. Counting total papers, for example, could reward those with many mediocre publications, whereas just counting highest-ranked papers may not recognize a large and consistent body of work.

    And it is hard to inflate one's own h-index, for example by self-citation.

    1. Ratings Games, Nature Next Article Bookmark and Share

      Excerpts: Yet those same researchers know how time-consuming peer assessment can be.

      Against that background, two new efforts to tackle the challenge deserve readers' attention and feedback. One, a citations metric, has the virtue of focusing explicitly on a researcher's cumulative citation achievements. The other, the next UK Research Assessment Exercise, is rooted in a deeper, more qualitative assessment, but feeds into a numerical rating of university departments, the results of which hang around the necks of the less successful for years.

      Excerpts: Seeking to deter terrorists, especially committed, utopian groups such as Al Qaeda willing to use weapons of mass destruction (WMD), poses significant challenges.1 Against what would one threaten to retaliate? What do these groups value? Unlike traditional states preoccupied with protecting territory and regime survival, terrorist groups use different scales to weigh costs and benefits, often calculating risks and evaluating rewards in ideological and religious terms. (...) it is tempting to assert that the only feasible ways to counter a WMD attack is prevention, by denying terrorist groups access to WMD through nonproliferation efforts, safeguards, and interdictions.
