  1. Complexity: The Bigger Picture, Nature Next Article Bookmark and Share

    Excerpts: If a concept is not well defined, it can be abused. This is particularly true of complexity, an inherently interdisciplinary concept that has penetrated a range of intellectual fields from physics to linguistics, but with no underlying, unified theory.

    (...) models of complex systems frequently result in a new conceptual interpretation of the behaviour. The aim is to capture the principal laws behind the exciting variety of new phenomena that become apparent when the many units of a complex system interact.


  2. Complexity-The Enemy Of Integration, Managing Information Strategies Next Article Bookmark and Share

    Excerpt: Complexity of integrated supply chain systems is not a business issue. It is a systems issue that the IT managers are responsible for. The key message is this: complexity is not inevitable, and the first step of dealing with it is to understand it.

    Complexity often places IT managers in a dilemma. Implementing a system to support complex supply chain processes can be of significant value to the business. But from the IT perspective, building and maintaining it can be a complex affair.


  3. Psychosocial Predictors Of Emerging Adults' Risk And Reckless Behaviors,   J. Youth and Adoles Next Article Bookmark and Share

    Abstract: The current study investigated risk and reckless behaviors in emerging adults using self-report measures and a cross-sectional design. Several of the major limitations associated with past research were overcome by sampling widely, making clear conceptual distinctions, avoiding confounds between predictors and criteria, developing more direct measures of key constructs, and controlling for demographic variables and for social desirability. In this sample of 375 emerging adults, ˇ§riskˇ¨ behaviors were found to be reliably predicted by sensation seeking, but not by antisocial peer pressure, whereas the reverse pattern of association was more true in relation to ˇ§recklessˇ¨ behaviors.

  4. Machine Learning In Real-Time Control Of Water Systems, Urban Water Next Article Bookmark and Share

    Abstract: In real-time control (RTC) of combined urban and rural water systems the so-called centralised control requires information from different locations in the water system and hence sensitive to the communication network breakdown during extreme storm runoff events. Optimisation algorithms used in advanced forms  require considerable computing times and thus may be impractical for RTC. To overcome these problems, the application of machine learning methods is proposed, using artificial neural networks and fuzzy adaptive systems. Results obtained in a realistic case study show that the trained controllers, can replicate centralised control behaviour quite accurately and rapidly, using only local data sources.

  5. Whole Better Than Parts, Nature Science update Next Article Bookmark and Share

    Excerpt: Computers are increasingly having to manage with imperfect components, as their power and complexity increases. One costly solution is simply to double up - to have a back-up system for every one that might fail.

    Alternatively, one can find a combination of components that works just about as well as one containing no defects at all, say Damien Challet and Neil Johnson of Oxford University. Parts do not necessarily have to be duplicated, discarded or bypassed just because they are imperfect.

    • Whole Better Than Parts, Faulty Components Can Make Almost Perfect Device, Philip Ball, Nature Science update, 02/07/02

  6. Genome Shuffling Of Lactobacillus For Improved Acid Tolerance, Nature Biotechnology Next Article Bookmark and Share

    Excerpt: Fermentation-based bioprocesses rely extensively on strain improvement for commercialization. Whole-cell biocatalysts are commonly limited by low tolerance of extreme process conditions such as temperature, pH, and solute concentration. Rational approaches to improving such complex phenotypes lack good models and are especially difficult to implement without genetic tools. (...) We identified new shuffled lactobacilli that grow at substantially lower pH than does the wild-type strain (...). Genome shuffling seems broadly useful for the rapid evolution of tolerance and other complex phenotypes in industrial microorganisms.

  7. Gene Regulation: The Brave New World Of RNA, Nature Next Article Bookmark and Share

    Excerpts: Most of the RNA transcribed from your genome doesn't make protein. (...) it functions in gene-regulatory networks that underlie the complexity of higher organisms.

    Biology's 'central dogma', laid down in the 1950s, states that genetic information flows from DNA to RNA to protein. Since then, numerous studies have shown that RNA does more than simply serve this intermediary function. (...) In multicellular organisms, (...) the majority of RNA molecules are the principal actors in largely unexplored networks of gene regulation.


  8. Biodiversity: Bacterial Game Dynamics, Nature Next Article Bookmark and Share

    Excerpts: Kerr et al. also show, however, that this loss of diversity occurs only if the bacterial populations are well mixed. Otherwise, all three strains survive. This conclusion has been predicted on paper: (...), that if dispersal of a population is limited and its interactions with other populations are localized, then diversity is protected to a large degree7, 8. This holds for an astonishing variety of scenarios, for instance in epidemiological models, community ecology, plant genetics, animal behaviour, molecular evolution9 and game theory10.

    1. Local Dispersal Promotes Biodiversity In A Real-Life Game Of Rock-Paper-Scissors,, Nature Next Article Bookmark and Share

      Excerpt:  One of the central aims of ecology is to identify mechanisms that maintain biodiversity. Numerous theoretical models have shown that competing species can coexist if ecological processes such as dispersal, movement, and interaction occur over small spatial scales. In particular, this may be the case for non-transitive communities, that is, those without strict competitive hierarchies. The classic non-transitive system involves a community of three competing species satisfying a relationship similar to the children's game rock-paper-scissors (...).

  9. Sperm Train To Win, Nature Science update Next Article Bookmark and Share

    Excerpts: Mouse sperm team up to speed their route to the egg. New research shows that hundreds of individuals form fast-swimming packs to give their genes the best chance against other males' sperm. (...)

    "They're like the carriages of a train," says Moore, who works at the University of Sheffield, UK. In the lab, trains can swell to thousands of sperm. In female mice they tend to number 50-200 cells.

    Groups travel roughly 50% faster than loners - especially in viscous fluid like that in the female reproductive tract.

    • Sperm Train To Win, Sperm Teams Out-Swim The Competition, John Whitfield, Nature Science update, 02/07/11

    1. Exceptional Sperm Cooperation In The Wood Mouse, Nature Next Article Bookmark and Share

      Summary: Spermatozoa from a single male will compete for fertilization of ova with spermatozoa from another male when present in the female reproductive tract at...

      Context: Several examples of sperm cooperation have been reported mainly in molluscs and insects. A possible exception in Mammalia is the spermatozoa of opossums that conjugate to form pairs during sperm maturation and disengage immediately.


  10. Theoretical Biology: Ants On A Turing Trail, Nature Next Article Bookmark and Share

    Excerpts: The behaviour of ants when dealing with their dead has parallels with biological pattern formation more generally, for instance as seen during development..(...)

    The observations indicate that a mechanism of short-range activation and long-range inhibition is at work. The activation would consist of a behavioural tendency to drop corpses with a probability that increases with the density of corpses in the immediate neighbourhood. (...) Inhibition occurs through the ants' tendency to pick up corpses and carry them for considerable distances, leading to the long-range depletion of the clusters.


  11. Sociogenomics Takes Flight, Science Next Article Bookmark and Share

    Excerpts: Winglessness in ants is part of a polyphenism, which can be defined as the "occurrence of several distinct phenotypes or forms in a given species, each of which develops facultatively in response to some cue from the internal or external environment". Polyphenism is not limited to invertebrates, (...), including fish that switch sexes in response to changes in their social environment. Polyphenism has figured prominently in the evolution of one of the defining features of insect societies: a division of labor for reproduction.

    1. Evolution of the Gene Network Underlying Wing Polyphenism in Ants, Science Next Article Bookmark and Share

      Excerpts: Wing polyphenism in ants evolved once, 125 million years ago, and has been a key to their amazing evolutionary success. (...) We show that the expression of several genes within the network is conserved in the winged castes of four ant species, whereas points of interruption within the network in the wingless castes are evolutionarily labile. The simultaneous evolutionary lability and conservation of the network underlying wing development in ants may (...) be a general feature of polyphenic development and evolution in plants and animals.


  12. Apoptosis: Repulsive Encounters, Nature Next Article Bookmark and Share

    Excerpt: These events have been interpreted as evidence that phagocytes can actively kill their prey, rather than simply consuming dead cells. But an alternative explanation is that a loss of repulsive signalling, and hence an attachment to phagocytes, occurs before the key apoptotic events - that is, before final commitment to cell death. In other words, phagocytes cross a 'point of no return' in their decision to eliminate dying cells before those cells are irrevocably committed to the decision to die.

  13. Entropy: Beads Of Doubt, BBC Online Next Article Bookmark and Share

    Excerpt: Scientists at the Australian National University (ANU) have carried out an experiment involving lasers and microscopic beads that disobeys the so-called Second Law of Thermodynamics, something many scientists had considered impossible.

    The finding has implications for nanotechnology - the design and construction of molecular machines. They may not work as expected.

    It may also help scientists better understand DNA and proteins, molecules that form the basis of life and whose behavior in some circumstances is not fully explained.


  14. On the Observability of Quantum Information Radiated from a Black Hole, arXiv Next Article Bookmark and Share

    Abstract: We propose a resolution to the black-hole information-loss paradox: in one formulation of physical theory, information is preserved and macroscopic causality is violated; in another, causality is preserved and pure states evolve to mixed states. However, no experiments can be performed that would distinguish these two descriptions. We explain how this could work in practice; a key ingredient is the suggested quantum-chaotic nature of black holes.

  15. It Slices! It Dices! Nanotube Struts Its Stuff, NYTimes Next Article Bookmark and Share

    Excerpts: It is stronger than steel and far sharper than a pin. It shoots electrons and draws away heat. It can become the thinnest of wires and, potentially, electronic devices almost as minuscule as molecules.

    In the last decade, the cylindrical molecule of carbon known as a nanotube has become a do-all wonder substance, touted for future use in everything from X-ray machines to paint. Nanotubes are already sprinkled in more than half of lithium ion batteries: their ability to carry electricity hastens recharging, and they act like tiny springs to hold apart the sheets of graphite in the battery, extending its lifetime.


  16. The Rise and Fall of the Church-Turing Thesis, arXiv Next Article Bookmark and Share

    Abstract: The essay consists of three parts. In the first part, it is explained how theory of algorithms and computations evaluates the contemporary situation with computers and global networks. In the second part, it is demonstrated what new perspectives this theory opens through its new direction that is called theory of super-recursive algorithms. These algorithms have much higher computing power than conventional algorithmic schemes. In the third part, we explicate how realization of what this theory suggests might influence life of people in future. It is demonstrated that now the theory is far ahead computing practice and practice has to catch up with the theory. We conclude with a comparison of different approaches to the development of information technology.

  17. Diversification Of Synaptic Strength: Presynaptic Elements, Nature Reviews Neuroscience Next Article Bookmark and Share

    Excerpts: Synapses are not static; their performance is modified adaptively in response to activity. Presynaptic mechanisms that affect the probability of transmitter release (...) are important in synaptic diversification. Here, we address the diversity of presynaptic performance and its underlying mechanisms: how much of the variation can be accounted for by variation in synaptic morphology and how much by molecular differences? Significant progress has been made in defining presynaptic structural contributions to synaptic strength; by contrast, we know little about how presynaptic proteins produce normally observed functional differentiation (...).

  18. Networking Comes Of Age, Nature Book Report Next Article Bookmark and Share

    Excerpt: They include, for example, the stories about the original work on the six degrees of separation (the idea that just five links can connect any two people), the many amusing tales about the legendary mathematician Paul Erdos and his contributions to random graph theory, and the advances on small-world networks by Strogatz and Watts. Many applications are introduced with compelling examples, such as the AIDS epidemic to describe virus propagation through complex networks, or the early development of the Internet.

    1. Small Word Network, English Words Are Connected, Nature Science update Next Article Bookmark and Share

      Excerpt: The researchers traced the links between 30,000 English words in an online thesaurus. For example, the word 'actor' can be connected to 'universe' through two intermediaries. The thesaurus lists 'character' as a synonym for 'actor'; 'character' is also equated with 'nature'; and 'nature' with 'universe'.

      Moving from 'actor' to 'universe' in the network of words therefore takes three steps. To the surprise of Motter and colleagues, they found that the same was true of just about any randomly chosen pair of words in the thesaurus.


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

    1. To Combat Terrorism, a Systems Approach is Vital, Wharton School Next Article Bookmark and Share

      Excerpts: (...) that it is crucial to understand the causes that drive groups such as Al Queda, (...). He cited several reasons why researchers should probe the causes of terrorism. "It serves predictive purposes, and it also allows pre-emptive intervention," Jenkins said. "Studying causes helps you learn how to deprive terrorists of their constituencies."

      The U.S. - historically - has put causes aside and instead focused on counter-terrorism. This is because U.S. policy on terrorism evolved in response to hijackings (...), and "what was affecting us was not causes but tactics"


    2. National Strategy Document for Homeland Security, The White House Next Article Bookmark and Share

      Excerpts: This document is the first National Strategy for Homeland Security. The purpose of the Strategy is to mobilize and organize our Nation to secure the U.S. homeland from terrorist attacks. This is an exceedingly complex mission that requires coordinated and focused effort from our entire society-the federal government, state and local governments, the private sector, and the American people.

      (...) The National Strategy for Homeland Security will help to prepare our Nation for the work ahead in several ways. It provides direction to the federal government departments and agencies that have a role in homeland security.


    3. Brookings Report Urges Congress to Revise President Bush's Homeland Security Proposal,, Brookings Press Briefing Next Article Bookmark and Share

      Excerpts: Good organization is necessary but not sufficient condition for carrying out this important task. Most important of all there's a need for strategy of homeland security to drive the organization not vice versa. We've been concerned that there has been a sort of slow-motion movement towards developing an overall homeland security strategy. Meanwhile the Administration has tried to move forward both on the budgetary and reorganization front and we think there's a danger of the tail wagging the dog here and that there is an important need for that strategy to be forthcoming so that Congress and the American people can debate it and see the reorganization in the context of that strategy. (...)

      This was a White House generated proposal. The people involved were all in the White House, there was nobody out of the departments as far as we know. In fact the Secretaries weren't informed of the proposal until about 18 hours before the President went public with it.


    4. Assessing the Department of Homeland Security,, The Brookings Institution Next Article Bookmark and Share

      Excerpt: But it is wrong to presume-as does the administration's proposal and much of the commentary on this issue-that the most effective way to organize this effort is to merge as many homeland security agencies and functions as possible into a single department. Just because a variety of functions contribute to homeland security does not mean that they necessarily need to be under common organizational control. Military force and diplomacy contribute to our national security, yet no one seriously argues that they should all be conducted by a single agency. It is simply not possible to bring all or most of the important homeland security entities into one department. Even the administration's very ambitious consolidation proposal leaves the Pentagon, the CIA, and the FBI untouched-yet, all play absolutely vital roles in the homeland security effort.
