  2. Scientists of Very Small Draw Disciplines Together, NYTimes Next Article Bookmark and Share

    Excerpts: Nanotechnology, biotechnology, electronics and brain research are converging into a field of science vital to the nation's security. (...) the natural world's ability to assemble atoms into complex tissues with very exact specifications may hold the key to making vast quantities of minute, inexpensive pollution sensors or solar cells. Bioengineers, (...), are looking to artificial nanostructures as possible drug delivery systems or as scaffolds to help injured organs repair themselves. Such convergence was given a name late in 2001: NBIC, for nanotechnology, biotechnology, information technology and cognitive science.

  3. Extracting Work from a Single Heat Bath via Vanishing Quantum Coherence, Science Next Article Bookmark and Share

    Excerpts: We present here a quantum Carnot engine in which the atoms in the heat bath are given a small bit of quantum coherence. The induced quantum coherence becomes vanishingly small in the high-temperature limit at which we operate and the heat bath is essentially thermal. However, the phase , associated with the atomic coherence, provides a new control parameter (...). The deep physics behind the second law of thermodynamics is not violated; nevertheless, the quantum Carnot engine has certain features that are not possible in a classical engine.

  4. Chemical Reactions Involving Quantum Tunneling, Science Next Article Bookmark and Share

    Excerpts: Understanding chemical reaction rates constitutes a central theme in chemistry. Classical theories have been tremendously successful in providing qualitative and quantitative insights into chemical reaction rates. Yet, a growing and remarkably varied number of chemical reactions deviate from classical behavior because of quantum effects (1). As Zuev et al. show on page 867 of this issue, these deviations can be enormous (2). Far from being mere curiosities or footnotes in the theory of chemical reaction rates, these quantum phenomena manifest themselves in "ordinary" chemical reactions (...)

    1. Quantum Dots As Dynamical Systems, Phil. Trans.: Math., Phy. & Engg. Sc., Next Article Bookmark and Share

      Abstract: Quantum dots show a range of time-dependent behaviours. Polarity-dependent phenomena are found even for nearly spherical stoichiometric clusters of ZnO and ZnS in studies based on interatomic potentials or on a lane-wave density-functional approach. We find a substantial dipole moment (...). This dipole causes a highly non-uniform spin-density distribution on electronic excitation or after a change in the dot's electronic charge state. We present the results of molecular dynamics of the ZnS particle embedded into the silica glass, and consider the role played by the soft modes in energy-dissipation processes (...) and energy transfer from the dot to the matrix.

  5. Is A Picture Worth 1,000 Words?, Nature Next Article Bookmark and Share

    Excerpts: Figures used to be part of the thought and discovery process. For Leonardo, Galileo and mathematicians such as Riemann, the image was part of the thought process. The same instrument penned words and drew lines. This seamless integration is more than a quaint sentimental point.A line is tentative; in a line drawing one hears the voice of the author: "this is what I think happens..." (...) Physics and mathematics have been held as primary examples of domains where images play no role.

  6. How Could Conscious Experiences Affect Brains?, CogPrints Next Article Bookmark and Share

    Abstract: In everyday life we take it for granted that we have conscious control of some of our actions and that the part of us that exercises control is the conscious mind. Psychosomatic medicine also assumes that the conscious mind can affect body states, and this is supported by evidence that the use of imagery, hypnosis, biofeedback and other ‘mental interventions' can be therapeutic in a variety of medical conditions. However, there is no accepted theory of mind/body interaction and this has had a detrimental effect on the acceptance of mental causation in science, philosophy and in many areas of clinical practice. Biomedical accounts typically translate the effects of mind into the effects of brain functioning, for example, explaining mind/body interactions in terms of the interconnections and reciprocal control of cortical, neuroendocrine, autonomic and immune systems. While such accounts are instructive, they are implicitly reductionist, and beg the question of how conscious experiences could have bodily effects. On the other hand, non-reductionist accounts have to cope with three problems: 1) The physical world appears causally closed, which would seem to leave no room for conscious intervention. 2) One is not conscious of one's own brain/body processing, so how could there be conscious control of such processing? 3) Conscious experiences appear to come too late to causally affect the processes to which they most obviously relate. This paper suggests a way of understanding mental causation that resolves these problems. It also suggests that "conscious mental control" needs to be partly understood in terms of the voluntary operations of the preconscious mind, and that this allows an account of biological determinism that is compatible with experienced free will.

    1. Making Sense of Causal Interactions Between Consciousness and Brain, CogPrints Next Article Bookmark and Share

      Abstract: My target article (henceforth referred to as TA) presents evidence for causal interactions between consciousness and brain and some standard ways of accounting for this evidence in clinical practice and neuropsychological theory. I also point out some of the problems of understanding such causal interactions that are not addressed by standard explanations. Most of the residual problems have to do with how to cross the "explanatory gap" from consciousness to brain. I then list some of the reasons why the route across this gap suggested by physicalism won't work, in spite of its current popularity in consciousness studies. My own suggested route across the explanatory gap is more subterranean, where consciousness and brain can be seen to be dual aspects of a unifying, psychophysical mind. Some of the steps on this deeper route still have to be filled in by empirical research. But (as far as I can judge) there are no gaps that cannot be filled-just a different way of understanding consciousness, mind, brain and their causal interaction, with some interesting consequences for our understanding of free will. The commentaries on TA examined many aspects of my thesis viewed from both Western and Eastern perspectives. This reply focuses on how dual-aspect monism compares with currently popular alternatives such as "nonreductive physicalism", clarifies my own approach, and reconsiders how well this addresses the "hard" problems of consciousness. We re-examine how conscious experiences relate to their physical/functional correlates and whether useful analogies can be drawn with other, physical relationships that appear to have dual-aspects. We also examine some fundamental differences between Western and Eastern thought about whether the existence of the physical world or the existence of consciousness can be taken for granted (with consequential differences about which of these is "hard" to understand). I then suggest a form of dual-aspect Reflexive Monism that might provide a path between these ancient intellectual traditions that is consistent with science and with common sense.

  7. Obesity and the Environment: Where Do We Go from Here?, Nature Next Article Bookmark and Share

    Excerpts: The obesity epidemic shows no signs of abating. There is an urgent need to push back against the environmental forces that are producing gradual weight gain in the population. (...), we estimate that affecting energy balance by 100 kilocalories per day (by a combination of reductions in energy intake and increases in physical activity) could prevent weight gain in most of the population. This can be achieved by small changes in behavior, such as 15 minutes per day of walking or eating a few less bites at each meal.

    1. 'Fat People and Bombs':HPA Axis Cognition, Structured Stress, and the US Obesity Epidemic, CogPrints Next Article Bookmark and Share

      Abstract: We examine the accelerating 'obesity epidemic' in the US from the perspective of recently developed theory relating a cognitive hypothalamic-pituitary-adrenal axis to an embedding 'language' of structured psychosocial stress. Using a Rate Distortion argument, the obesity epidemic is found to represent the literal writing of an image of a ratcheting pathological social hierarchy onto the bodies of American adults and children. This process, while stratified by the usual divisions of class and ethnicity, is nonetheless relentlessly engulfing even affluent majority populations. Our perspective places the common explanation that 'obesity occurs when people eat too much and get too little exercise' in the same category as the remark by US President Calvin Coolidge on the eve of the Great Depression that 'unemployment occurs when large numbers of people are out of work'. Both statements ignore profound structural determinants of great population suffering which must be addressed by collective actions of equally great reform.

  8. Major Research to "Crack" Cancer Gene Mystery, health-news.co.uk Next Article Bookmark and Share

    Excerpts: Researchers from the UK and the Netherlands are to launch a major research project in the hope of identifying the cluster of genes associated with cancer. In their investigation, which will build on the success of the human genome project, the scientists will look at nearly 10,000 genes, inactivating one at a time to find out precisely what they do and how they contribute to the development of cancer. This, they hope, could lead to the creation of new drugs that target rogue cancer-causing genes.

    1. DNA Repair: Damage Alert, Nature Next Article Bookmark and Share

      Excerpts: Radiation and other harmful influences frequently damage our genes, potentially causing diseases such as cancer. New work reveals a surprising mechanism that notifies the cellular defence system about DNA damage. Among the many types of damage that arise in DNA, the most deadly are double-strand DNA breaks (DSBs) (...). (...) can activate ATM, which then adds phosphate groups to (phosphorylates) several target proteins. These proteins are in turn linked into a signaling network that slows the cells' progression through the cell-division cycle, and stimulates DNA repair.

  9. A Mathematical Model Of Tissue Replacement During Epidermal Wound Healing, Appl. Math. Modelling Next Article Bookmark and Share

    Abstract: A mathematical model, which describes the control of the development and growth of a healing unit, is presented. The replacement of epidermal injured tissue, which is controlled by a negative feedback mechanism, is modeled in one-dimensional geometry. The model is based on diffusion equations (...). The results of the model suggest that the normal healing of a circular epidermal wound depends on the oxygen supply, and in order for successful healing to take place, the oxygen concentration within the wound space must be at low levels.

  10. The Gene That Causes The Smell Of The Earth And Leads Camels To Water, Alphagalileo Next Article Bookmark and Share

    Excerpts: (...) have discovered the gene that gives freshly turned soil its distinctive smell. A smell, it is believed, that enables camels to find water in the desert. The 'earthy' smell is caused by geosmin, a chemical produced by a common bacterium, Streptomyces coelicolor (...). "The smell of Streptomyces may be a matter of life and death to the camel but these bacteria are also of enormous importance to humans as they are a major source of the antibiotics we use in medicine. By shutting down the bacteria's ability to produce geosmin we can make the factories less smelly neighbours."

  11. Neurophysiology: Sensing Temperature Without Ion Channels, Nature Next Article Bookmark and Share

    Excerpts: Mammals use cold-sensitive ion channels to translate information abou the temperature of their surroundings into electrical signals that are taken up by thermoreceptor nerve cells. Here I investigate the thermoelectric properties of an extracellular gel removed from the electrosensors of sharks, and show that it develops significant voltages in response to tiny temperature gradients. This bulk property of the gel indicates that temperature can be translated into electrical information without the need for ion channels, a sensitivity that may help sharks to locate thermal fronts as feeding areas.

  12. Researchers Unwind Secrets Of Biological Clocks, ScienceDaily Next Article Bookmark and Share

    Excerpts: It may be only pond scum, the sort of green gunk that clogs lakes and floats in on the tides. But inside, a clock is quietly ticking. Even this lowly one-celled bacterium has a biological clock, the sophisticated internal timing device that governs the daily rhythms of people, animals and plants, (...) eventually could lead to cures for sleep and mood disorders, as well as other medical problems. Golden and her colleagues also study the biological clocks of birds, rats and fungi, but it was the bacterium known as Synechococcus elongatus that yielded the latest revelation: the first structural model of part of the clockworks.

  13. Scientists Target Microorganisms to Break Down Toxic Pesticide, Environmental News Network Next Article Bookmark and Share

    Excerpts: A pesticide used extensively all over the world is receiving attention these days more for methods being used to clean it up than for its use as chemical to control insects and mites. Endosulfan, classified as an organochlorine (the same family as DDT), is registered for use as a pesticide on 60 U.S. crops. Its residues have been found in the atmosphere, soils, sediments, surface and ground waters, and food. (...) Researchers from the University of California-Riverside and the University of Agriculture, Faisalabad, Pakistan, recently identified specific microorganisms which can breakdown the toxicity of endosulfan. Detoxifying pesticides through biological means is receiving serious attention as an alternative to existing methods, such as incineration and landfill, which are not sufficient for large, contaminated sites.

  14. A Tax Code Not Intended for Amateurs, NYTimes Next Article Bookmark and Share

    Excerpts: Not so long ago, Washington managed to hack through much of the underbrush of the tax code in an overhaul that President Ronald Reagan signed into law in 1986. But in the years after, lawmakers started adding dozens of provisions to the individual and corporate income tax systems, contributing to their complexity (...). This year's instruction manual for the federal government's individual income tax adds up to 126 pages, a far cry from the 56 pages needed in 1987, after the revision took effect.

  15. Technology: What Are the Chances?, NYTimes Next Article Bookmark and Share

    Excerpts: The field, known in professional jargon as probabilistic risk assessment, helps companies and government agencies decide whether they are prepared to take the chances involved. In 1995, these tools helped a NASA consultant estimate the risk of a catastrophic space shuttle failure at 1 in 145, or about 0.7 percent, for each mission. NASA accepted that risk. Similar methods are used to estimate the health risks at toxic-waste sites, to secure nuclear laboratories, weapon stockpiles and power plants, and to determine the safety and reliability of planes and cars.

  16. Tangled Up in Spam, NYTimes Next Article Bookmark and Share

    Excerpts: Spam is not just a nuisance. It absorbs bandwidth and overwhelms Internet service providers. Corporate tech staffs labor to deploy filtering technology to protect their networks. The cost is now widely estimated (though all such estimates are largely guesswork) at billions of dollars a year. The social costs are immeasurable: people fear participating in the collective life of the Internet, they withdraw or they learn to conceal their e-mail addresses, identifying themselves as user@domain.invalid or someone@nospam.com. The signal-to-noise ratio nears zero, and trust is destroyed.

  17. Physical Growth In A Transitional Economy: The Aftermath Of South African Apartheid, Econ. & Human Biol. Next Article Bookmark and Share

    Abstract: This paper examines the effect of post-apartheid economic and social transition on the growth and development of urban children. Whilst these children were born with lower birth weights than in developed countries, they did grow strongly in infancy, particularly in weight (...). While post-apartheid social and economic changes were expected to take some time to affect child growth and development, the rate of change has been slower than expected. (...) growth of White children continues to be superior to that of their non-White peers and differences that existed at birth and during infancy have not diminished during childhood and early adolescence.

  18. Modelling Political Instability And Economic Performance: Israeli Investment During The Intifada, Economica Next Article Bookmark and Share

    Abstract: I construct a model of investment in Israel that incorporates both standard economic factors and indicators of political instability and unrest. The model is used to estimate both the extent to which the Intifada has depressed Israeli investment in different kinds of capital good, and the size of the corresponding 'peace dividend'.

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

    1. Simulating Ants' Behavior May Help U.S. Fight Future Wars, Defense News Next Article Bookmark and Share

      Excerpts: Some Pentagon researchers believe this type of naturally occurring phenomenon, in which a decentralized group achieves a common goal, may guide the armed forces of the future. Several labs are working on ways to model the behavior of swarms, whether of ants, unmanned aerial vehicles or even infantry soldiers. "Swarm intelligence is a shift in mindset: from centralized control to decentralized control and distributed intelligence; from predefined solutions that may break down with the first glitch ¡K to emergent, self-organizing strategies and tactics," said Eric Bonabeau, chief scientist for Icosystem Corp.

    2. Zacarias, My Brother: The Making of a Terrorist, NYTimes Next Article Bookmark and Share

      Excerpts: Extremists know how to cultivate people's weaknesses, the better to manipulate them. One such weakness is pride. It is a sweet song to the prideful ear to be promised membership in the religious and intellectual elite, to be "above" mere mortals. Language, here, is a valuable tool for extremists. Wahhabis have a vocabulary all their own, designed to forge a sense of group cohesion. All those who are not like them are kuffar, heathens. Their leaders are khalifes, emirs. Warriors are mujahideen.
