  1. The Unstable Path To Cancer,, Science Next Article Bookmark and Share

    Excerpts: For a cell, maintaining the integrity of its genome is of paramount importance. If it fails in this task and manages to divide anyway, both of its daughter cells may inherit an abnormal chromosome complement, with potentially dire consequences. In addition to subtle genetic mutations, most cancer cells show dramatic karyotypic changes, including gains and losses of chromosomes, gross chromosomal rearrangements, (...), although scientists are still wrestling with the issue of whether this genome instability causes cancer or merely arises after a cell is already well along the path to malignancy.

    1. Debate Surges Over the Origins of Genomic Defects in Cancer,, Science Next Article Bookmark and Share

      Excerpts:  Cancer cells are chock-full of mutations and chromosomal abnormalities, (...). Increasingly, the debate is focusing on the role of genomic instability: some kind of inherent defect that makes the cancer cell genome more susceptible than that of normal cells to developing the various abnormalities. Some researchers maintain that genomic instability is needed early on to set cells on the path to cancer. Others maintain that genomic instability might contribute to cancer's ability to spread in the body, but that it's not necessary for a cancer to occur.


    2. Versatile Cells Against Intractable Diseases,, Science Next Article Bookmark and Share

      Excerpts: The attention given to embryonic stem cells has kindled excitement about the possibilities for using an array of cells to rebuild damaged nerve tissue

      The nervous system itself is a morass of complexity, comprising a spectrum of cell types. First are the glial cells (...), which provide network support, housekeeping, and insulation functions for neurons. These are the cells affected in multiple sclerosis (MS). Then come the "transmitter-defined neurons"--that is, cells whose main job is releasing a particular brain chemical in a particular location, (...).


  2. Stem Cells Rescue Retina, Nature Science update Next Article Bookmark and Share

    Excerpt: Bone marrow stem cells might one day deliver drugs to the eye, halting age- and diabetes-related blindness. The cells can treat a genetic condition that causes mouse retinas to degenerate1.

    When the stem cells - that usually make blood vessels - were injected into the fluid-filled space of the eye they became part of developing blood vessels in the retina.

    Faulty capillary formation is central to both the leading causes of adult blindness in the US: diabetic retinopathy and age-related macular degeneration.


  3. Communicating with Einsteins, Darwin Magazine Next Article Bookmark and Share

    Excerpt: Workers with exceptional technical skills predominate in many modern work environments. These highly talented and trained specialists can occupy many business niches beyond technology, including accounting, finance, research and development, and others. Our research examines the techniques that the manager can use to better lead, motivate and reward these highly intelligent employees, which our publisher chose to label "Einsteins."

    Understanding and using good management skills and approaches are a given. But we've found that tailoring those skills slightly to fit these individuals can aid recruitment, retention and morale.


    1. Virtual People Help Bridge Digital Divide, BBC News Next Article Bookmark and Share

      Excerpts: "In general people do not like interacting with machines; they would rather have a warm body," she said, "but an avatar is the next best thing." (...) Behind the avatar is months of work (...).

      This has been tied together with conversation maps to make the avatars able to answer questions on a wide range of topics. (...)

      Users ask questions and respond to the voice of the avatar by typing but eventually it is hoped that people will be able to talk directly to the avatar.


  4. Multiscale Entropy Analysis of Complex Physiologic Time Series, Phys. Rev. Let. Next Article Bookmark and Share

    Abstract:: There has been considerable interest in quantifying the complexity of physiologic time series, such as heart rate. However, traditional algorithms indicate higher complexity for certain pathologic processes associated with random outputs than for healthy dynamics exhibiting long-range correlations. This paradox may be due to the fact that conventional algorithms fail to account for the multiple time scales inherent in healthy physiologic dynamics. We introduce a method to calculate multiscale entropy (MSE) for complex time series. We find that MSE robustly separates healthy and pathologic groups and con­sistently yields higher values for simulated long-range correlated noise compared to uncorrelated noise.

  5. Suggested Critical Behaviour of a Biologically Inspired Neural Network Model, arXiv Next Article Bookmark and Share

    Abstract: It has been suggested by Bak, Stassinopoulos, Chialvo and others that the brain operates at a critical level. In this letter, we examine a neural network proposed to model this, the simple three-layer version of the Chialvo-Bak 'minibrain' (...), and present numerical results which suggest that it does indeed display critical (scale-free) behaviour (...). The cause of this behaviour is identified as interference between active paths in the network, and an heuristic analogy is drawn with Bak, Chen and Tang's forest-fire model.

  6. Stock Market Swings Help Researchers Understand Extreme Events In Solar Wind, ScienceDaily Next Article Bookmark and Share

    Excerpts: Astrophysicists at the University of Warwick have applied data analysis methods used to model stock market fluctuations, to explore changes in the solar wind (the sun's expanding atmosphere). They have discovered that the fluctuations in the solar wind follow the same kinds of patterns seen in the stock markets ¡V particularly when it comes to the number of extreme events or large fluctuations. The researchers (...) used "finite size scaling" to look at the probability of fluctuations or jumps in magnetic energy density in the solar wind, using data from the NASA-WIND spacecraft.

  7. Dogs Said To Have Basic Math Skills, CNN/Reuters Next Article Bookmark and Share

    Editor's Note: The test used to study "math skills" of dogs are similar to the ones used to test math skills of infants.

    Excerpts: Dogs also know when they are being short-changed on treats because they have a basic mathematical ability which enables them to tell when one pile of objects is bigger than another. (...)

    Robert Young of Brazil's Pontifical Catholic University of Minas Gerais in Belo Horizonte, tested the theory on 11 mongrels using dog treats.

    The canines were shown treats and then a screen was lowered and the goodies were left as they were or some were added or taken away.


  8. Boeing's Challenge To The Laws Of Physics, Financial Times Next Article Bookmark and Share

    Excerpts: The result, he maintains, is a repulsive action on any object the beam hits, that is proportional to its mass. (...)Mr Podkletnov says, his laboratory installation has already demonstrated its ability to knock over objects more than a kilometre away.

    (...) impulse gravity generator that grabbed the attention of Boeing. In the Grasp briefing document, Boeing describes how the 4in beam shot from the device is reportedly immune to all electro-magnetic shielding and that it goes through anything that gets between it and the target.


  9. Agent Computing Themes in Models of Learning and Development,  Int J Develop Neuroscience Next Article Bookmark and Share

    Abstract: After evaluating general features and attributes of the agent notion, the overlap of features in candidate (attribute) cores, and several less central features, the paper addresses agent and related theory in neuroscience, observing how agent notions have penetrated portions of this field and how the field itself emphasizes and further develops some agent themes via, e.g. schema theory, neural net-artificial intelligence (AI) comparisons, and other research. In remaining sections, models for development of memory strategies in children are presented, illustrating cooperative and competitive neural modeling agents, an active role for a "human agent in the loop," and integrating broadly-based neural network (NN) modeling with other bio-inspired models.

  10. Adaptive Learning and Coloniality in Birds, arXiv Next Article Bookmark and Share

    Abstract: We introduce here three complementary models to analyze the role of predation pressure in avian coloniality. Different explanations have been proposed for the existence of colonial breeding behavior in birds, but field studies offer no conclusive results. We first propose a learning model in which the decision of birds are taken according to the collective performance. The properties of the system are then studied according to a model in which birds choose according to their individual experience, and the agreement of the introduction of spatial structure with field data are then shown.

  11. Modularity And Spatial Reorientation In A Simple Mind, Cognition Next Article Bookmark and Share

    Abstract: When disoriented in environments with distinctive geometry, such as a closed rectangular arena, human infants and adult rats reorient in accord with the large-scale shape of the environment, but not (...) as the colour of a wall. Human adults, however, conjoined geometric and nongeometric information to reorient themselves, which has led to the suggestion that spatial processing tends to become more flexible over development and evolution. We here show that fish tested in the same tasks perform like human adults and surpass rats and human infants. These findings suggest that the ability to make use of geometry for spatial reorientation (...).

  12. Thought Before Language: How Deaf And Hearing Children Express Motion Events, Cognition Next Article Bookmark and Share

    Abstract: Do children come to the language-learning situation with a predetermined set of ideas about motion events that they want to communicate? We explored these questions by comparing the gestures produced by Chinese and American deaf children (...). We found that, even in the absence of any conventional language model, deaf children conveyed the central elements of a motion event in their communications. More surprisingly, deaf children growing up in an American culture used their gestures to express motion events in precisely the same ways as deaf children growing up in a Chinese culture. In contrast, hearing children in the two cultures expressed motion events differently (...).

  13. Immunology: The Virtue Of Tolerance, Nature Next Article Bookmark and Share

    Excerpts: If specific immune responses could be toned down without completely suppressing immunity, it would provide a boon for the treatment of transplant rejection, autoimmune disease and allergy.

    (...) some patients naturally achieve this state of tolerance, in which the immune system learns to accept a target that it would ordinarily attack. (...) if doctors could induce tolerance at will, the prospects for transplant patients would greatly improve - immunosuppressive drugs may prevent organ rejection, but by damping down the entire immune system, they render patients susceptible to infections and cancer.


  14. Silencing Viruses With RNA,, Nature Next Article Bookmark and Share

    Excerpts: Until recently, the two major ways to combat viral infections were vaccines and drugs that are targeted to specific viral enzymes or other viral proteins. (...), RNA interference (RNAi), which prevents the expression of genes by using small RNA molecules, such as 'small interfering RNAs' (siRNAs). This technology in turn takes advantage of the fact that RNAi is a natural biological mechanism for silencing genes in most, if not all, cells of many living organisms, from plants to insects to mammals.

    1. Short Interfering RNA Confers Intracellular Antiviral Immunity In Human Cells, Nature Next Article Bookmark and Share

      Excerpts: Gene silencing mediated by double-stranded RNA (dsRNA) is a sequence-specific, highly conserved mechanism in eukaryotes. In plants, it serves as an antiviral defence mechanism. Animal cells also possess this machinery but its specific function is unclear4-10. Here we demonstrate that dsRNA can effectively protect human cells against infection by a rapidly replicating and highly cytolytic RNA virus. Pre-treatment of human and mouse cells with double-stranded, short interfering RNAs (siRNAs) to the poliovirus genome markedly (...) promotes clearance of the virus from most of the infected cells.

    2. Number of Genes Limited by Presence of Adaptive Immune System?,  Trends in Immunology Next Article Bookmark and Share

      Contributing Editor's Note: T-cells are an essential part of cell immunity which play major role in recognizing foreign antigenes. During education of all T-cells in thymus those T-cells which have T-cell receptor which can recognize and react with individual's own tissues(self-antigenes), are eliminated. However, the thymic education process is not foolproof, and some T-cells meant to be eliminated are escaping. If such autoimmune(selfimmune) cells become activated they can initiate immune response that results in autoimmune disease.

      Abstract: The factors that are important in limiting the number of functional genes contained within the genome of an organism are presently unknown. Here, it is suggested that in organisms that contain an adaptive immune response, the number of genes in the genome might be limited by the need to delete autoreactive T cells, thus preventing autoimmunity. The more genes an organism has, the more autoantigens are generated, necessitating an increase in the proportion of T cells that are deleted.


  15. New Horizons Of Nerve Repair: Proteins In Nerve Regeneration System, ScienceDaily Next Article Bookmark and Share

    Excerpts: It's sticky, it's a gel, it comes in a tube, but this is no greasy kids' stuff. Rather, it's a novel delivery system for peripheral nerve regeneration that could have implications for successful stem cell delivery and spinal cord repair. (...) has designed a system that employs a nerve guide tube filled with a gel containing growth factor proteins that stimulate nerve regeneration. Also part of the package are strategically placed sugars and peptides for binding in the gel matrix. The system has promoted peripheral nerve regeneration in preliminary rat studies.

  16. Sonoluminescence: Inside A Micro-Reactor, Nature Next Article Bookmark and Share

    Excerpts: Gas bubbles in a liquid can convert sound energy into light [under the influence of ultrasound, Ed.].(...)

    The extreme conditions inside the bubble are adjustable through external parameters such as forcing pressure or water temperature, so the bubble can be considered as a controlled high-temperature reaction chamber, offering opportunities to measure reaction rates in extreme temperature and pressure regimes.

    (...). Before this knowledge can be applied to sonochemistry - the enhancement of chemical reactions through ultrasound in a bubbly fluid - a better understanding of bubble-bubble interactions will be needed.


    1. Photons, Radicals And Ions During Single-Bubble Cavitation,, Nature Next Article Bookmark and Share

      Excerpts:  Single-bubble sonoluminescence (SBSL) has attracted much attention owing to both the apparent simplicity of its creation and the complexity of processes occurring during bubble pulsation. (...) At appropriate acoustic intensities, the bubble can emit short ( 50-500 ps) flashes of light with clock-like regularity. (...) suggested the existence of extraordinary temperatures inside the bubble, with black-body effective temperatures as high as 20,000 K. (...), so SBSL is now generally believed to be due, at least in part, to black-body radiation, bremsstrahlung and ion-electron recombination processes.


  17. Mathematician Fills in a Blank for a Fresh Insight on Art,, NYTimes Next Article Bookmark and Share

    Excerpts: Escher was creating a distortion with a well-known mathematical property: if you look at small regions of the distorted picture, the angles between lines have been preserved. "Conformal maps," (...).

    Knowing that Escher's distortion followed this principle, Dr. Lenstra was able to use elliptic curves to convert his rough approximation of the distortion into an exact mathematical recipe. (...)

    In the center of the mathematician's version, the mysterious blank patch is filled with another, smaller copy of the distorted quayside scene, turned almost upside-down.

    Excerpts: The Millennium Project of the American Council for the United Nations University, a massive ongoing effort involving about 1,250 futurists from over 50 countries, publishes the State of the Future report each year. This year's report has six sections, covering global challenges, the State of the Future Index ["described as "a statistical analysis of key indicators and forecast that depict whether the future promises to be better or worse.", Ed.], long-range goals for the year 2050, counterterrorism, management and policy implications of future science and technology issues, and future international environmental security issues and potential military requirements.

  19. Complex Challenges: Global Terrorist Networks Next Article Bookmark and Share

    1. Judge Rebuffs Detainees at Guantánamo, NYTimes Next Article Bookmark and Share

      Excerpts: The authorities also said they thought the base would be out of reach of American courts.(...)

      Both parties, she said, were seeking for the court to issue a writ of habeas corpus (...).

      "Although Defense Department officials have acknowledged that some of the detainees at Guantánamo are completely innocent and don't belong there, none have been allowed to meet or speak with their families or with counsel, and none have even been informed of the charges, if any, against them," Mr. Wilner said.


    2. Judge Orders Names of Sept. 11 Detainees Released, NYTimes, Next Article Bookmark and Share

      Excerpts:  The ruling was a significant setback to the Bush administration's policy of secret detentions of immigrants in connection with the investigation into the terrorist attacks.

      Judge Gladys Kessler, of the United States District Court for the District of Columbia, dismissed the Justice Department's argument that disclosure would hinder its investigation of terrorists. (...)

      Judge Kessler noted that the government has said it had detained 751 individuals on immigration violations over the course of its Sept. 11 investigation. As of June 13, only 74 still remained in custody.


    3. Scientists Worry Journals May Aid Terrorists, NYTimes Next Article Bookmark and Share

      Several requests, he said, concerned DNA primers, the snippets of DNA used to extract specific genes from an organism. One application of primers is in sensors designed to quickly detect microbes in a biological attack. An adversary's genetic engineers could foil the sensors if they knew what primers were used.

      But Dr. Atlas said he feared that if authors were allowed to withhold information, the journals might find themselves publishing papers that could not be reproduced.


    4. An Insecure Alliance,, WorldLink Next Article Bookmark and Share

      Excerpts: The US, unsurprisingly, has different priorities. Stunned by its vulnerability, it seeks above all immediate security. (...) From its friends and allies Washington wants cooperation without constraint. Coalitions of the willing, yes; new treaties, charters and conventions, no. (...)

      The immediate sources of tension are obvious enough: the consternation in Europe at Mr Bush's "axis of evil" speech, European frustration with the US administration's reluctance to use its political and diplomatic authority to mediate a settlement in the Middle East, (...).


    5. Al Qaeda Forming New Cells Worldwide Next Article Bookmark and Share

      Excerpt: Al Qaeda members who fled Afghanistan after the U.S.-led counter-terrorism offensive began last fall are forming what anti-terror coalition intelligence analysts are calling "super cells" in locations stretching from North Africa to Southeast Asia.

      Coalition intelligence said al Qaeda operatives in coalition custody told their interrogators that men who trained in Afghan camps run by Osama bin Laden have returned to their home nations. There, they have formed alliances with other extremist groups to create "super cells," while the main al Qaeda leadership struggles to regroup, sources said.
