NASA Satellite Measures Earth's Carbon Metabolism, ScienceDaily
Excerpts: In honor of the Earth Day celebration, NASA scientists unveiled the first consistent and continuous global measurements of Earth's "metabolism." This new measurement is called net production because it indicates how much carbon dioxide is taken in by vegetation during photosynthesis minus how much is given off during respiration. "We are literally watching the global garden grow. We now have a regular, consistent, calibrated and near-real-time measure of a major component of the global carbon cycle for the first time. This measure can also be the basis for monitoring the expansion of deserts, the effects of droughts (...)."
Ecological Economics At The Crossroads Between Normal And Post-Normal Science, Ecol. Economics
Abstract: In this paper we address some potential difficulties ecological economics (EE) might be confronted with in its further development. EE has evolved with intent to tackle the urgent problems human society faces today, in particular the ones related to environmental and ecological issues. To deal with such problems, a new concept of science different from disciplinary, normal science seems to be necessary. We will present post-normal and mode-2 science as two examples of such a concept. The importance of this new concept (...) lies in the fact that the set of values behind it can be seen as a `regulative principle' (...).
`Full' World Versus `Empty' World Paradigm At The Time Of Globalisation, Ecol. Economics
Abstract: The Mediterranean region is characterised by a high diversity mainly due to the integration between natural (land heterogeneity) and human (stewardship) processes. Cultural landscapes are the results of such coevolutive processes. Plasticity, adaptation to disturbance, and the persisting of biological refugia can be considered the most relevant factors responsible for the Mediterranean dynamics. In this commentary the full world paradigm is presented as an extension of the concept of resilience and ascendancy to propose a new grammar that incorporates self-organisation of natural and human dominated systems into a process of diffuse globalisation of economics and human behaviour.
On Coalition Formation: Durable Coalition Structures, Math. Social Sc.
Abstract: We define a solution to the problem of coalition formation (...). Coalition structures satisfying our requirements are called durable, and we interpret them as much more likely to last than those coalition structures not satisfying the requirements, which we call transient. Durability results from a combination of foresight and extreme risk aversion on the part of agents, when considering to join others to disrupt an existing structure in search of higher gains. Agents' calculations are also constrained to satisfy a strong consistency requirement, which is reflected in the recursive structure of our definition.
Excerpts: Resources enter the blood stream via surfaces--the gut lining for nutrients and water, and the alveoli of the lungs for oxygen. The key point, and source of the fourth dimension, is the fact that the terminating units through which resources pass into the blood stream, (...) The total area of resource exchange, (...), therefore scales in three dimensions. (...) The total blood volume is then a product of the terminating unit's total area, which scales in three dimensions, and the average distance between source and destination, which scales in one.

Chaos Theory May Help Explain Patterns Of Alcohol Abuse, Studies Suggest, ScienceDaily
Excerpts: Chaos theory, which helps scientists understand complex systems such as weather patterns and the stock market, may also help shed light on the dynamics of alcohol abuse (...) used techniques of chaos theory to do a case study of the drinking patterns of an alcohol abuser over several years. (...) the results suggest that alcohol abusers may show signs of improvement that are really just part of the natural cycle of their disease and not indicative of true recovery. They analyzed the data and created various time series - including daily, weekly and monthly - to determine patterns in his drinking.
Modelling The Dynamics Of Reasoning Processes: Reasoning By Assumption, Cognitive Sys. Res.
Abstract: To model the dynamics of cognitive processes, often the dynamical systems theory (DST) is advocated. However, for higher cognitive processes such as reasoning and certain forms of natural language processing the techniques adopted within DST are not very adequate. This paper shows how an analysis of the dynamics of reasoning processes can be made using (...) temporal traces consisting of sequences of reasoning states over time to describe reasoning processes. It is shown for the example reasoning pattern `reasoning by assumption', how relevant dynamic properties can be identified and expressed using a temporal trace language.
Words Get In The Way, Talk Is Cheap, But It Can Tax Your Memory, Science News
Excerpts: Law-enforcement officials typically solicit descriptions of criminals from eyewitnesses, often just after an offense has occurred. (...) Eyewitnesses can then pick the criminals out of a lineup. (...) A series of laboratory studies found that memories for a mock criminal's face were much poorer among eyewitnesses who had described what the perpetrator looked like shortly after seeing him, compared with those who hadn't. Psychologist Jonathan W. Schooler of the University of Pittsburgh, who directed the studies, dubbed this effect "verbal overshadowing of visual memories."
Wiring the Brain with Insulin, Science
Excerpts: Insulin's most important task is to control blood glucose levels, (...). Insulin and its relatives are also produced in the brain, where they are thought to promote neuronal survival and modulate synaptic transmission. (...) insulin signaling is also essential for ensuring that the nervous system is wired correctly during development. Song et al. (1) present evidence that insulin signaling contributes to guidance of photoreceptor cell axons from the retina to the brain during development of the visual system in the fruit fly Drosophila.
Axons Guided by Insulin Receptor in Drosophila Visual System, Science
Excerpts: Insulin receptors are abundant in the central nervous system, but their roles remain elusive. Here we show that the insulin receptor functions in axon guidance. (...) Insulin receptors in the central nervous system have been implicated in control of food uptake, learning, and memory, and pathophysiologies such as Alzheimer's disease . Drosophila harbor one receptor tyrosine kinase of the insulin receptor family (7-9), which avoids genetic redundancy in mammals that have three members of the insulin receptor family .
Scientists Discover Unique Source of Postnatal Stem Cells, NIDCR
Excerpts: Scientists report for the first time that "baby" teeth, the temporary teeth that children begin losing around their sixth birthday, contain a rich supply of stem cells in their dental pulp. The researchers say this unexpected discovery could have important implications because the stem cells remain alive inside the tooth for a short time after it falls out of a child's mouth, suggesting the cells could be readily harvested for research. According to the scientists, who published their findings online today in the Proceedings of the National Academy of Sciences1, the stem cells are unique compared to many "adult" stem cells in the body. They are long lived, grow rapidly in culture, and, with careful prompting in the laboratory, have the potential to induce the formation of specialized dentin, bone, and neuronal cells. If followup studies extend these initial findings, the scientists speculate they may have identified an important and easily accessible source of stem cells that possibly could be manipulated to repair damaged teeth, induce the regeneration of bone, and treat neural injury or disease.
Baby Teeth Revealed As Source Of Stem Cells, NewScientist.com
Excerpts: (...) teeth are a source of stem cells. The cells could help repair damaged teeth and perhaps even treat neural injuries or degenerative diseases. Currently, researchers can isolate two types of stem cells. Embryonic stem cells can develop into any cell in the body, but their harvesting requires the destruction of embryos, which pro-life groups oppose. Adult stem cells avoid this problem, but have more limited abilities. Now it appears that the stem cells from children's lost teeth could provide an intermediate and easily accessible source.
The Grid: Tomorrow's Computing Today, Nature
Excerpts: The physics lab that gave us the World Wide Web is now gearing up to make the first practical deployment of the Internet's next big thing: the Grid. (...) From an ordinary-looking Linux PC, you submit a supercomputing job in high-energy physics. A few hours later, the Grid tells you the results are ready. To be frank, I'm underwhelmed. (...) "Grids will have succeeded when they become invisible to the user; when we stop talking about them," he says.
Million-User Online Game Previewed, NewScientist.com
Excerpts: Creating a large virtual world that does not repeat itself is very time consuming and hence expensive (...). The large multiplayer games currently online usually take one world and then repeat it. For example, the game Everquest supports 450,000 users, but is split into 32 segregated segments. In contrast, Rekonstruction will aim to provide up to a million users with a single unique world. To try to overcome the problem of creating the vast amount of unique content needed, automated programs will be employed to generate the virtual world (...).
Internet Is Losing Ground in Battle Against Spam, NYTimes
Excerpt: In the cat-and-mouse game of e-mail marketers and those trying to stop them, the spammers are still winning. So far, nothing that has been tried to block spam has done much more than inconvenience mass e-mailers. Just as Ms. Sachs's company, NetGlobalMarketing, has been able to reword its e-mail to evade spam filters, others use even more aggressive tricks to disguise the content of their messages and to send them via circuitous paths so their true origin cannot be determined.
Exploiting Sublanguage and Domain Characteristics in a Bootstrapping Approach to Lexicon and Ontology Creation, arXiv
Abstract: It is very costly to build up lexical resources and domain ontologies. Especially when confronted with a new application domain lexical gaps and a poor coverage of domain concepts are a problem for the successful exploitation of natural language document analysis systems that need and exploit such knowledge sources. In this paper we report about ongoing experiments with `bootstrapping techniques' for lexicon and ontology creation.
Contributing Editor's Note: "Ontologies" specify conceptializations, so that software agents can "understand" the semantic content of a document. Until now, most ontologies are being created manually, but this is far from practical, especially taking into consideration the aims of the Semantic Web. Algorithms for ontology creation are a necessary step in the development of the "next generation" Internet.
Wi-Fi's Broken Promise, Darwin Mag
Excerpts: For now, any service provider that uses equipment certified by the Wi-Fi Alliance will earn the right to display the Wi-Fi Zone logo. Users will be able to visit http://www.wi-fizone.org to locate hot spots in their hometowns or traveling destinations, (...). The idea is to have a universally recognized logo that anyone can see and know that wireless Internet service is available at a location, similar to the way a telephone logo identifies a phone booth (...).

Excerpt: Software-defined radios can reconfigure themselves automatically to recognize and communicate with each other. This could impose order on the current Babel-like chaos of competing wireless standards (CDMA, GSM, TDMA, and countless others), transforming today's rigid networks into nimble, open systems. The big payoff: improved system performance, cheaper service cost, and seamless roaming. With instant reprogramming, you can carry a single gadget for multiple uses. A cell phone becomes a garage door opener, which morphs into a mobile gaming device, which then - presto! - turns itself into a TV remote.
Evolutionary Approach In Personal Communication Networks, Comp. Communications
Abstract: This paper proposes an evolutionary approach to solve the problem of assigning cells to switches in the planning phase of mobile cellular networks. Well-known in the literature as an NP-hard combinatorial optimization problem, this problem requires the recourse to heuristic methods, which can practically lead to good feasible solutions, not necessarily optimal, the objective being rather to reduce the convergence time toward these solutions. Computational results obtained from extensive tests confirm the effectiveness of this approach to provide good solutions to problems of a certain size.
Pictorial Analysis: a Multi-resolution Data Visualization Approach for Monitoring and Siagnosis of Complex Systems, Information Sciences
Abstract: This paper aims to describe the prospective methodology (Pictorial Analysis) of a human-computer interaction capable to select and adjust visual representations for better feature and pattern selection. As an adequate tool for on-line monitoring and diagnosis of very complex systems which require human supervision in addition to the computerized one, our approach exploits human capabilities of pattern recognition in doing data analysis and selecting appropriate representations, features and class descriptions by means of interactive human-computer learning. It is based on the analysis of multidimensional relations through transforming the initial data (heterogeneous arrays, signals and fields) into artificial pictures. Practical applications of this approach prove it extremely useful in critical areas of safety, such as flight control, power plant monitoring, etc.
Engineers Aim To Make Average Singers Sound Like Virtuosos, Purdue News
Excerpt: Karaoke may never be the same, thanks to research being presented in Nashville detailing the latest findings in efforts to create a computerized system that makes average singers sound like professionals. (...) Far more work is needed before the system is finished, Smith said. He said the specialized programs are, however, able to alter certain important characteristics of a person's voice, such as pitch, duration, and "vibrato," or the modulation in frequency produced by professional singers. (...) using a mathematical method called the fast Fourier transform (...)
Colony Insularity Through Queen Control On Worker Social Motivation In Ants, Proc. Biol. Sc.
Abstract: We investigated the relative contribution of the queen and workers to colony nestmate recognition cues (...). Workers were either individually isolated, preventing contact with both queen and workers (colonial deprived, CD), kept in queenless groups, allowing only worker-worker interactions (queen deprived, QD) or in queenright (QR) groups. Two weeks post-separation QD and QR workers were amicable towards each other but both rejected their CD nestmates, which suggests that the queen does not measurably influence the colony recognition cues. Therefore, while workers supply and blend the recognition signal, the queen affects worker-worker interaction by reducing social motivation and tolerance of alien conspecifics.
Fruit Set Of Highland Coffee Increases With The Diversity Of Pollinating Bees, Proc. Biol. Sc.
Abstract: The worldwide decline of pollinators may negatively affect the fruit set of wild and cultivated plants. Here, we show that fruit set of the self-fertilizing highland coffee (Coffea arabica) is highly variable and related to bee pollination. In a comparison of 24 agroforestry systems in Indonesia, the fruit set of coffee could be predicted by the number of flower-visiting bee species, and it ranged from ca. 60% (three species) to 90% (20 species). Diversity, not abundance, explained variation in fruit set, so the collective role of a species-rich bee community was important for pollination success.
Abstract: In many species, older males are often preferred mates because they carry 'good' genes that account for their viability. How females discern a male's age is a matter of question. However, for animals that rely heavily on chemical communication there is some indication that an animal's age can be determined by its scent. To investigate (...) mice were trained in a Y-maze to discriminate urine odours of donor mice of different ages: Adult (3-10 months old) and Aged (more than 17 months old). Trained mice could discriminate between these two age groups by odour alone.

Activity Driven Adaptive Stochastic Resonance, Phys. Rev. Lett.
Abstract: Cortical neurons in vivo show fluctuations in their membrane potential of the order of several millivolts. Using simple and biophysically realistic models of a single neuron we demonstrate that noise induced fluctuations can be used to adaptively optimize the sensitivity of the neuron's output to ensembles of subthreshold inputs of different average strengths. Optimal information transfer is achieved by changing the strength of the noise such that the neuron's average firing rate remains constant. Adaptation is fast, because only crude estimates of the output rate are required at any time.
Military Robots To Get Swarm Intelligence, NewScientist.com
Excerpts: A battalion of 120 military robots is to be fitted with swarm intelligence software to enable them to mimic the organised behaviour of insects. (...) The project is run by US software company Icosystems, which specialises in creating programs that mimic behaviours found in nature. Their software will use simple rules to co-ordinate complex behaviour among the robots. (...) The 120 robots were built for the US military by I-Robot, a company co-founded by robotics pioneer Rodney Brooks. (...)unforeseen circumstance could throw the robots into chaos.
Abstract: The paper describes a system for open-ended communication by autonomous robots about event descriptions anchored in reality through the robot's sensori-motor apparatus. The events are dynamic and agents must continually track changing situations at multiple levels of detail through their vision system. We are specifically concerned with the question how grounding can become shared through the use of external (symbolic) representations, such as natural language expressions.

The Unmanned Army, NYTimes
Excerpts: For the Joint Chiefs, the fog of war was lifted to a much greater extent. The trillions of megabytes of real-time data that flowed from the front lines to mission control were an exponential increase over transmissions in the 1991 campaign, giving generals (...) as far away as the Pentagon virtually unprecedented knowledge of battle conditions, resistance, losses and enemy positions. Decisions could be made more remotely, field commanders observed more closely and middlemen effectively cut out of the chain of command for the sake of speed and efficiency.
Seeking Connections: H. Eugene Stanley, Nature
Excerpts: You have the audience in your hands, but some smart-alec asks you the killer question you have no idea how to answer. What's your response? I would simply admit that I had no idea how to answer the question, throw it open to the audience and invite participants to discuss it later on. After all, the right question can lead to something new. What book currently resides on your bedside table? None. I do not read books. Especially not in bed.
Complex Challenges: Global Terrorist Networks
Fate of Prisoners From Afghan War Remains Uncertain
Excerpts: Many international lawyers have argued that the United States is obliged under the Geneva conventions to hold tribunals to determine whether the detainees are prisoners of war. If they are, they contend, they should have been released when the fighting in Afghanistan ended. But the United States says the Guantanamo inmates are "unlawful combatants," and do not qualify for prisoner-of-war status. (...) "The U.S. has paid a huge price in international opinion," he said. "In Britain, people see Guantanamo as a symbol of American defiance of international norms."
U.S. Warns Iraqis Against Claiming Authority in Void, NYTimes
Excerpts: The American military moved today to strip Baghdad's self-appointed administrator of his authority and warned Iraqi factions not to take advantage of the confusion and the political void in the country by trying to grab power. Lt. Gen. David McKiernan, the commander of ground forces in Iraq, issued a proclamation putting Iraq's politicians on notice, saying, "The coalition alone retains absolute authority within Iraq." He warned that anyone challenging the American-led authority would be subject to arrest. (...) "Nobody has authority unless General McKiernan says so,"
Online, All the Time, an All-Seeing Surveillance System, NYTimes
Excerpts: (...) ease with which the high-tech surveillance cameras can be set up and used worries people who are concerned about the invasion of privacy. (...) network of cameras mounted at busy intersections, in the subway system and at tourist sites like the National Mall. The system, which is activated during heightened terror alerts, allows the authorities to manipulate the cameras so they can, (...), pan and zoom in on activity they consider suspicious. The remote access also means that officers can view images on computer monitors installed in squad cars.
