  1. Untangling the Future, Business 2.0 Next Article Bookmark and Share

    Excerpt: Today's cutting-edge research can be broken into four main areas -- infotech, materials science, bioscience, and energy -- each with its own group of subspecialties. Click this diagram to see a pdf of ways in which many of those subspecialties could merge in the future, giving rise to new disciplines like

  2. We Like The Look Of Lookalikes, Nature Science Update Next Article Bookmark and Share

    Excerpt: Lisa DeBruine of McMaster University in Hamilton, Ontario, got volunteers to play a game in which they could either divide a sum of money between themselves and another player or trust the other player to divide a larger sum.

    She showed them a picture of the person they were playing with, and told them that players would interact over the Internet.

    In fact, the opponents' responses were programmed into the computer. And some pictured faces were composites including elements from the subject's own face, created using morphing software.


  3. Collective Choice With Shared Knowledge Structures, J. of Math. Psycho. Next Article Bookmark and Share

    Abstract: Complex decision making typically involves many agents attempting to aggregate many alternatives. If agents' preferences are unconstrained, cyclic outcomes are highly probable. In contrast, we show that if agents share similar models of the choice domain, then a stable collective outcome occurs with about 90% probability. These results have implications for systems of interacting agents, such as group decisions by individuals in social settings or interpretations of sense data by competing perceptual modules of a brain.

  4. Neurobiology: Understanding The Consequences, Nature Next Article Bookmark and Share

    Excerpt: First, Brembs et al. looked at the electrical activity of the oesophageal nerve in whole animals, and found that it increased when the animals ingested food. Presumably, this activity signals the presence of a reward - food. Next, Brembs et al. 'trained' the animals to associate spontaneous biting (whether or not food was ingested) with a reward by stimulating the oesophageal nerve, mimicking the usual reward signal, during biting. The result was that the molluscs made significantly more spontaneous bites than controls, both immediately and 24 hours after training.

  5. Visual Features Of Intermediate Complexity, Nature NeuroScience Next Article Bookmark and Share

    Abstract: The human visual system analyzes shapes and objects in a series of stages (...). The first stages use simple local features, and the image is subsequently represented in terms of larger and more complex features. These include features of intermediate complexity and partial object views. Here we show that intermediate complexity (IC) features are optimal for the basic visual task of classification. Moderately complex features are more informative for classification than very simple or very complex ones, and so they emerge naturally by the simple coding principle of information maximization with respect to a class of images.

    1. Feature-Based Attention In Human Visual Cortex, Nature NeuroScience Next Article Bookmark and Share

      Abstract: The content of visual experience depends on how selective attention is distributed in the visual field. We used functional magnetic resonance imaging (fMRI) in humans to test whether feature-based attention can globally influence visual cortical responses to stimuli outside the attended location. Attention to a stimulus feature (color or direction of motion) increased the response of cortical visual areas to a spatially distant, ignored stimulus that shared the same feature.


  6. Self-Organization And Selection In The Emergence Of Vocabulary, Complexity Next Article Bookmark and Share

    Abstract: Abstract: Human language may have started from a consistent set of mappings between meanings and signals. These mappings, referred to as the early vocabulary, are considered to be the results of conventions (...). In this study, we report simulation models for investigating how such conventions can be reached. We propose that convention is essentially the product of self-organization of the population through interactions among the agents and that cultural selection is another mechanism that speeds up the establishment of convention. The combination of these two complementary mechanisms, i.e., self-organization and cultural selection, provides a plausible explanation for cultural evolution (...).

  7. Numbers in Mind, Science News Next Article Bookmark and Share

    Excerpts: Babies show signs of being versatile counters. They can tally not just items and groups but also small numbers of actions and sounds, Wynn finds. In one experiment, half of a group of 6-month-olds watched a puppet jump up and down twice, then pause briefly before executing additional pairs of hops. (...) Babies gradually lost interest in each routine and spent less time looking at the puppet's capers.

    In an ensuing session, the same infants saw the puppet switch between short sets of two jumps and three jumps.

  8. Nerves Tell Arteries to Make Like a Tree, Science Next Article Bookmark and Share

    Summary: By the time an embryo's heart beats for the first time, an extensive tree of arteries is already in place. Its delicate branches--which will ultimately stretch tens of thousands of kilometers in a full-grown human--ensure that no bit of tissue goes wanting for oxygen and nutrients.

    How arteries shape themselves into such fine patterns has been an open question. Now a study shows that arteries follow the lead of another of the body's branching specialists: nerves.


    1. A Generation Gap in Brain Activity,, Science Next Article Bookmark and Share

      Excerpt: As the field of cognitive neuroscience matures, researchers are using imaging studies to get a better fix on what happens to the brain as it ages. Some researchers have observed that certain brain areas physically shrink over time, whereas others have found that the patterns of neural activity in 60- or 70-year-olds often bear little resemblance to those in the 20-something subjects who populate most brain functional imaging studies. Exactly how these changes relate to cognitive failings in old age remains unclear, however.


  9. Growth Patterns of Microscopic Brain Tumors,, arXiv Next Article Bookmark and Share

    Abstract: Highly malignant brain tumors such as Glioblastoma Multiforme (GBM) form complex growth patterns in vitro in which invasive cells organize in tenuous branches. Here, we formulate a chemotaxis model for this sort of growth. A key element controlling the pattern is homotype attraction, i.e., the tendency for invasive cells to follow pathways previously explored. We investigate this in two ways: we show that there is an intrinsic instability in the model, which leads to branch formation. We also give a discrete description for the expansion of the invasive zone, and a continuum model for the nutrient supply. The results indicate that both, strong heterotype chemotaxis and strong homotype chemo-attraction are required for branch formation within the invasive zone. Our model thus can give a way to assess the importance of the various processes, and a way to explore and analyze transitions between different growth regimes.

  10. Microbial Subversion Of The Immune Response, PNAS Next Article Bookmark and Share

    Excerpts: A microbe becomes a pathogen by evading to a greater or lesser extent the immune defenses of its host. The mechanisms that have evolved for so doing are legion in number and striking in their diversity and ingenuity. They involve mechanisms to evade recognition by and mechanisms to subvert the effector mechanisms (...). An almost ubiquitous target for these subversion mechanisms is the complement system and it is with the subversion of complement by smallpox virus that the report in this issue of PNAS (...) is concerned.

    1. Variola Virus Immune Evasion Design, PNAS Next Article Bookmark and Share

      Excerpts: Variola virus, the most virulent member of the genus Orthopoxvirus, specifically infects humans and has no other animal reservoir. Variola causes the contagious disease smallpox, which has a 30-40% mortality rate.

      SPICE [SmallPox Inhibitor of Complement Enzymes, Ed.] provides the first evidence that variola proteins are particularly adept at overcoming human immunity, and the decreased function of VCP suggests one reason why the vaccinia virus vaccine was associated with relatively low mortality. Disabling SPICE may be therapeutically useful if smallpox reemerges.


  11. Bacterium Versus Fungus, Science Next Article Bookmark and Share

    Summary: Many of the bacteria that cause many animal diseases likely evolved in a broad ecological system, (...). Hogan and Kolter (p. 2229 ) have observed a range of antagonistic interactions among a selection of mutants of two commonly coexisting opportunistic pathogens,(...). The bacterium attaches by its poles to the filamentous form of the fungus, developing a biofilm over the filaments and finally killing the fungus. (...). When under assault, the fungus reverts into a yeastlike form that appears to be impervious to the bacteria.

    1. An Ecological Role for Virulence Factors, Science Next Article Bookmark and Share

      Excerpt: Interactions between prokaryotes and eukaryotes are ubiquitous. Although the pathogenic and symbiotic relationships bacteria have with plants and animals have garnered the most attention, the prokaryote-eukaryote encounters that occur among microbes are likely far more common. Many of the virulence factors that we study in the context of human disease may also have an ecological role within microbial communities.

      Bacteria and unicellular eukaryotes, such as yeasts and filamentous fungi, are found together in a myriad of environments and exhibit both synergistic and antagonistic interactions.


    2. Viral Manipulation Of The Cell Death Program,, J Gen Virol. Next Article Bookmark and Share

      Abstract: Many viruses have as part of their arsenal the ability to modulate the apoptotic pathways of the host. It is counter-intuitive that such simple organisms would be efficient at regulating this the most crucial pathway within the host, given the relative complexity of the host cells. Yet, viruses have the potential to initiate or stay the onset of programmed cell death through the manipulation of a variety of key apoptotic proteins.


  12. Symbiosis Has Deep Roots, Nature Science Update Next Article Bookmark and Share

    Excerpt: A few plants, including peas and beans, form symbiotic relationships with bacteria that convert atmospheric nitrogen into ammonia. In return for the ammonia, the plants give carbohydrates to the bacteria, which dwell in nodules on their roots.

    Gyorgy Kiss and colleagues at the Hungarian Academy of Sciences in Szeged have now identified, in alfalfa and peas, the receptor molecule that responds to bacteria's requests to set up home. They call the protein NORK.

     


  13. Quirks of Fetal Environment Felt Decades Later, Science Next Article Bookmark and Share

    Excerpts: "We pass more biological milestones before we are born than we'll ever pass at any other point in our lives," (...). Scientists have long believed that these milestones are molded by the environment an embryo, and later a fetus, encounters in the womb. Without enough folate, a fetus can't build and seal a backbone, for instance; a deluge of alcohol can interfere with delicate nervous system wiring; and certain medications taken by the mother might inhibit limb growth in the fetus she carries.

  14. Intercellular Communication in the Mammalian Ovary, Science Next Article Bookmark and Share

    Excerpt: The production of functional female gametes is essential for the propagation of all vertebrate species. The growth of oocytes within ovarian follicles and their development to mature eggs have fascinated biologists for centuries (...). Recent studies have revealed key roles of the oocyte (...) and established that bidirectional communication between the oocyte and companion somatic cells is essential for development of an egg competent to undergo fertilization and embryogenesis. The challenge for the future is to identify the factors that participate in this communication and their mechanisms of action.

     


  15. Physiology: Dynamic Instabilities In The Inflating Lung, Nature Next Article Bookmark and Share

    Excerpt: In lung diseases such as asthma1, expiratory flow becomes limited2, airways can collapse3 and the vital exchange of gases is compromised. Here we model the inflation of collapsed regions of the lung during inspiration in terms of avalanches propagating through a bifurcating network of airways, and find that the accompanying cascade of dynamic pressure instabilities - avalanche 'shocks' - manifests as negative elastic resistance of the lung. Our analysis of this apparent thermodynamic paradox provides a better understanding of aeration in the deep regions of the lung, (...)

  16. On The Evolution Of Cells,, PNAS Next Article Bookmark and Share

    Excerpts: A theory for the evolution of cellular organization is presented. The model is based on the (data supported) conjecture that the dynamic of horizontal gene transfer (HGT) is primarily determined by the organization of the recipient cell. (...)As a cell design becomes more complex and interconnected a critical point is reached where a more integrated cellular organization emerges, and vertically generated novelty can and does assume greater importance. This critical point is called the "Darwinian Threshold" for the reasons given.

    1. Transposable Elements And The Evolution Of Eukaryotic Complexity, Curr Issues Mol Biol. Next Article Bookmark and Share

      Abstract: Eukaryotic transposable elements are ubiquitous and widespread mobile genetic entities. These elements often make up a substantial fraction of the host genomes in which they reside. For example, approximately 1/2 of the human genome was recently shown to consist of transposable element sequences. (...) A sample of this evidence is reviewed here with an emphasis on the role that transposable elements may have played in driving the evolution of eukaryotic complexity. A number of specific scenarios are presented that implicate transposable elements in the evolution of the complex molecular and cellular machinery that are characteristic of the eukaryotic domain of life

  17. Russia Can Save Kyoto, If It Can Do the Math, Science Next Article Bookmark and Share

    Excerpts: The U.S. withdrawal from international negotiations over carbon emissions last year dealt a blow to the Kyoto Protocol that many thought might be fatal. A year on, however, Russia has emerged as an unlikely savior. (...)

    What led Russia to become an environmental champion? Its economy has traditionally relied on smokestack industries and burning fossil fuels, and until recently climate change was seen benignly as an antidote for shoveling snow. But the treaty gives the cash-strapped Russian government a financial incentive to think green.


  18. Pentagon Gets Defensive Over Missile Secrets,, Nature Next Article Bookmark and Share

    Excerpts: The Pentagon is planning new restrictions on the results of ballistic-missile defence tests - angering outside scientists who have until now monitored the tests and, on occasion, taken issue with the declared results.

    Data from future tests involving target warheads and decoys will be classified as secret to prevent enemies from learning about the system's weaknesses, (...).

    (...) Theodore Postol, (...):. "I think it's very clear why they're classifying information about the targets," he says. "It's because they can't tell the difference between decoys and deployed warheads."

    1. Re-Engineering The Drug Business, NYTimes Next Article Bookmark and Share

      Excerpt: Transportation becomes paramount, consolidation and vertical integration -- those cherished buzzwords of merger-hungry multinationals -- impossible. As a result, the narcotics industry has adapted what might be called the Osama bin Laden approach to management: base your operation in remote safe havens, the more war-torn and chaotic the better; stay small and shifty; use specialized subcontractors or freelancers on a need-to-know basis; vary your routes and routines whenever possible; and most important, always insulate yourself with plenty of expendable intermediaries in case someone gets caught and talks.

    2. War on Terror Makes for Odd Twists in Justice System,, NYTimes Next Article Bookmark and Share

      Editor's Note:  The hasty activities triggered in the US by the 9/11 attack, overthrow political, economic, and legal structures that have been well established for many years; they remind a physicist of "critical fluctuations" during phase transitions.

      Excerpts: (...) two Americans are being held in military brigs without access to lawyers, while two foreigners accused of terrorist activities are being tried in federal court with the full range of protections usually accorded to Americans.

      This patchwork approach has revealed a flexibility in the justice system but also what critics call an overly broad assertion of presidential authority.

      The government contends it can detain people until the hostilities are over - whenever that is - without charging them or giving them access to lawyers.


    3. Plane in Restricted Airspace Near White House Exposes a Security Weakness,, NYTimes Next Article Bookmark and Share

      Excerpt: Air traffic controllers in Baltimore first spotted the unidentified light aircraft heading toward Washington just before 8 p.m. Wednesday. The Air Force scrambled two F-16 fighters after the plane entered restricted airspace over the capital a few minutes later.

      But before the streaking jets got close enough to intercept the single-engine plane, it was close enough to the White House to hit the building had the pilot wanted to, the authorities said today.


    4. More Governments Choose To Use Linux, Not Windows, Gridtoday Next Article Bookmark and Share

      Excerpt: In Peru, a bill was proposed mandating the use of open-source software, such as Linux, on government computers. The bill said proprietary software poses a national security risk because the secret code could contain "back doors" for someone to break in.

    5. Energy In The 21st Century: What Americans Need To Know,, Brookings Institution Next Article Bookmark and Share

      Excerpt: The world runs on energy, primarily energy generated from coal and petroleum. The global war against terrorism and the tensions in the Middle East have raised new questions about the reliability of Americaˇ¦s oil supply from that region. Concerns about global climate change have focused increased attention on the search for cleaner fuels and energy generating methods. Russiaˇ¦s determination to become a major petroleum supplier, OPECˇ¦s periodic moves to restrict oil production, and rising energy needs in China and other developing countries are further complicating the situation.
