StarMine service, free on Yahoo, measures "analyst recommendation performance."(...)
StarMine measures analyst recommendation performance on a 1-to-5 scale, representing the return performance of an analyst's recommendations relative to his or her peers. To reach the scocres, StarMine analyzes every recommendation, upgrade and downgrade published by thousands of sell-side analysts around the world. Analysts are measured in two ways: on an absolute scale (used in the industry rankings) and on a coverage-relative scale (used for an analyst's overall score). Only analysts scoring 4 or 5 stars are displayed.
The Origin Of Speech, Science
Excerpts: Archaeologists have identified various milestones in human behavior in the 5-million-year evolutionary void between animal communication and human speech, but there is no consensus on which achievements imply the capacity for language. For example, the first stone tools date to 2.4 million years ago; some researchers think this may indicate linguistic facility, but others argue that toolmaking is far removed from speech. (...) 2 million years ago, when the hominid brain began a period of rapid expansion, including in the primary brain areas associated with producing or processing language (...).

Why Anatolia?, Science
Excerpts: (...) both the seeds of the Indo-European language and the gateway for the spread of agriculture into Europe some 8000 years ago. Recent research at a number of Anatolian sites has shown that this huge plateau was teeming with human populations, rich with art and culture, and home to the grains, cereals, and legumes key to the expansion of farming. "Everybody agrees that farming came to Europe from Anatolia," says (...) Colin Renfrew, chief partisan of the farming-dispersal model of Indo-European origins.

Towards a New Functional Anatomy of Language, Cognition
Abstract: The classical brain-language model derived from the work of Broca, Wernicke, Lichtheim, Geschwind, and others has been useful as a heuristic model that stimulates research and as a clinical model that guides diagnosis. However, it is now uncontroversial that the classical model is (i) empirically wrong in that it cannot account for the range of aphasic syndromes, (ii) linguistically underspecified to an extent that prohibits contact with the language sciences, and (iii) anatomically underspecified. We briefly summarize some of the central issues that motivate why a new functional anatomy of language is necessary, in the context of introducing a collection of articles that describe systematic new attempts at specifying the new functional anatomy. The major convergent observations are highlighted and the emergent conceptual and empirical trends are identified.
Emergent Properties Of CNS Neuronal Networks As Targets For Pharmacology, Progress in Neurobiology
Abstract: CNS [Central Nervous System, Ed.] drugs may act by modifying the emergent properties of complex
CNS neuronal networks. Emergent properties are network characteristics that are not predictably based on properties of individual member neurons.
Neuronal membership within networks is controlled by several mechanisms, including burst firing, gap junctions, endogenous and exogenous neuroactive substances, extracellular ions, temperature, interneuron activity, astrocytic integration and external stimuli. The effects of many CNS drugs in vivo may critically involve actions on specific brain loci, but this selectivity may be absent when the same neurons are isolated from the network in vitro where emergent properties are lost.
Cortical processing of complex sound: a way forward?, Trends in Neurosciences
Abstract: The organization of the cortical auditory system remains controversial. In
particular, the extent to which there is regional specialization in the cortical
processing of complex sound is unclear. Here, we ask whether we are
currently asking the right questions of auditory cortex, or using the appropriate
techniques to do so. A key factor that will promote such understanding in the
future will be increasing dialogue between workers using electrophysiological
recording methods to assess the response properties of single neurons and
those using imaging techniques to map regional organization. In the future,
further insights will be obtained by efforts to test hypotheses developed on the
basis of one approach by the use of the other. Imaging can tell the
neurophysiologists where to look, and work on single neurons can constrain
network models based on imaging. There is a crucial need for better
understanding of the anatomy of the auditory cortex in different species and for
comparative studies that will underpin both approaches.
Memories Light Up The Corners Of Our Minds, ScienceDaily
Excerpts: Memories do indeed light up the corners of our mind, just as the songwriter said. Scientific evidence for this notion comes from studies using magnetic resonance imaging to examine the living human brain. These studies show that certain brain areas "light up" as an individual is learning information. Scientists had previously established that people remember emotionally charged events and facts better than neutral ones. Now researchers at MIT have discovered that memories with an element of arousal or excitement are remembered by a different area of the brain-the amygdala-from memories of a calmer nature, which are remembered by the prefrontal cortex
Understanding Environmental Complexity Through A Distributed Knowledge Network, BioScience
Abstract: Understanding environmental complexity and other dimensions of ecological systems necessitates a holistic approach that can be achieved only by identifying, retrieving, and synthesizing diverse data from distributed sources; by collaborating with other scientists from a broad range of disciplines; and by investigating many different systems. Knowledge Network for Biocomplexity is developing new software tools to advance ecological understanding through discovery, access, retrieval, and management of distributed and heterogeneous ecological and environmental data. To address the need for cultural change in ecologists and other environmental scientists (...) training a cadre of young investigators (...) with emphasis on multiscale integration and synthesis.
Evolving a Stigmergic Self-Organized Data-Mining, arXiv
Abstract: Self-organizing complex systems typically are comprised of a large number of frequently similar components or events. Through their process, a pattern at the global-level of a system emerges solely from numerous interactions among the lower-level components of the system. Moreover, the rules specifying interactions among the system's components are executed using only local information, without reference to the global pattern, which, as in many real-world problems is not easily accessible or possible to be found. Stigmergy, a kind of indirect communication and learning by the environment found in social insects is a well know example of self-organization, providing not only vital clues in order to understand how the components can interact to produce a complex pattern, as can pinpoint simple biological non-linear rules and methods to achieve improved artificial intelligent adaptive categorization systems, critical for Data-Mining. On the present work it is our intention to show that a new type of Data-Mining can be designed based on Stigmergic paradigms, taking profit of several natural features of this phenomenon. By hybridizing bio-inspired Swarm Intelligence with Evolutionary Computation we seek for an entire distributed, adaptive, collective and cooperative self-organized Data-Mining. As a real-world, real-time test bed for our proposal, World-Wide-Web Mining will be used. Having that purpose in mind, Web usage Data was collected from the Monash University's Web site (Australia), with over 7 million hits every week. Results are compared to other recent systems, showing that the system presented is by far promising.
Learning User Similarity And Rating Style For Collaborative Recommendation, Info. Retrieval
Abstract: Information filtering is an area getting more important as we have long been flooded with too much information, where product brokering in e-commerce is a typical example. Systems which can provide personalized product recommendations to their users have gained a lot of interest in recent years. Collaborative filtering is one of the commonly used approaches which normally requires a definition of user similarity measure. In this paper, we propose the use of machine learning techniques to learn the optimal user similarity measure as well as user rating styles for enhancing recommendation acurracy. We have evaluated our proposed (...).
Cancer Without Disease, Nature
Excerpts: (...) body's inherent capacity to prevent the majority of these in situ tumours from recruiting their own new blood supply, thus preventing further growth owing to a lack of oxygen and nutrients. In the absence of a new supply of blood vessels by a process known as angiogenesis, an in situ tumour can remain dormant indefinitely. Paradoxically, it is proposed that angiogenesis itself is under the control of many genes in our body known to promote cancer (oncogenes) or suppress growth of tumours (tumour suppressors)

The Complex Interaction Of Aerosols And Clouds, Science
Excerpts: Aerosols have an important effect on atmospheric chemistry throughout the troposphere and lower stratosphere. They influence the radiative budget of Earth directly and indirectly by the modification of the cloud droplet size spectrum and precipitation at the surface. Researchers are beginning to incorporate these effects into the most sophisticated climate models for shallow clouds. This is because aerosol-cloud interactions are seen as one of the most important single forces that drive climate change, but there are big uncertainties in the current understanding of these processes.
Measurement Of The Effect Of Amazon Smoke On Inhibition Of Cloud Formation, Science
Abstract: Urban air pollution and smoke from fires have been modeled to reduce cloud formation by absorbing sunlight, thereby cooling the surface and heating the atmosphere. Satellite data over the Amazon region during the biomass burning season showed that scattered cumulus cloud cover was reduced from 38%in clean conditions to 0%for heavy smoke (...). This response to the smoke radiative effect reverses the regional smoke instantaneous forcing of climate from -28 watts per square meter in cloud-free conditions to +8 watts per square meter once the reduction of cloud cover is accounted for.

Mucus Good for the Local Economy, Science Now
Excerpts: Coral are nothing to sneeze at when it comes to generating mucus. One species common in Australia's Great Barrier Reef, for example, can exude up to 4.8 liters of mucus per square meter of reef a day. Scientists knew that the goo keeps the coral from drying out and protects them from infection, but now a research team proposes that the slime doesn't just help the coral. It helps the entire reef ecosystem save energy by recycling nutrients.
Phylogenetic Constraints And Adaptation Explain Food-Web Structure, Nature
Excerpts: Food webs are descriptions of who eats whom in an ecosystem. Although extremely complex and variable, their structure possesses basic regularities. (...) Until now, two models have been devised (...). Here, we propose a new model built on the hypothesis that any species' diet is the consequence of phylogenetic constraints and adaptation. Simple rules incorporating both concepts yield food webs whose structure is very close to real data. Consumers are organized in groups forming a nested hierarchy, which better reflects the complexity and multidimensionality of most natural systems.
Abstract: Sixty four members of the public were exposed to the same staged conversation either while waiting in a bus station or travelling on a train. Half of the conversations were by mobile phone, so that only one end of the conversation was heard, and half were co present face-to-face conversations. Analysis of variance showed that mobile phone conversations were significantly more noticeable and annoying than face-to-face conversations at the same volume when the content of the conversation is controlled. Indeed this effect of medium was as large as the effect of loudness. Various explanations of this effect are explored, (...).

Long-Term Working Memory And Interrupting Messages In Human - Computer Interaction, Behav. & Info. Tech.
Abstract: The extent to which memory for information content is reliable, trustworthy, and accurate is crucial in the information age. Being forced to divert attention to interrupting messages is common, however, and can cause memory loss. The memory effects of interrupting messages were investigated in three experiments. In Experiment 1, attending to an interrupting message decreased memory accuracy. In Experiment 3, an interrupting message was shown to be most disturbing when it was semantically very close to the main message. (...) it is argued that interrupting messages can both disrupt the active semantic elaboration (...) and cause semantic interference upon retrieval.
The Minority Game: An Introductory Guide, arXiv
Abstract: The Minority Game is a simple model for the collective behavior of agents in an idealized situation where they have to compete through adaptation for a finite resource.

Abstract: Inequality among social classes or castes is a frequent cause of conflict in human society. In social insects such as ants, bees and wasps, individuals can develop as one of two castes, queen or worker. (...) studied Melipona stingless bees native in tropical America where each individual bee can determine its own caste development. If each bee chose its caste only for the good of the colony, almost all should be workers. But this is not what happens. Up to 15% were selfish, developing as queens even if they carried out no work in the colony.
Patterns And Coevolutionary Consequences Of Repeated Brood Parasitism, Alphagalileo & Biol. Lett.
Abstract: While many parasitic cuckoos lay eggs mimicking host eggs, other brood parasites, including cowbirds, lay distinct eggs. Yet cowbird hosts do not typically eject odd-looking eggs. During our colourbanding studies of two species of cowbird hosts, many females were parasitised multiple times during their lifespan. We then examined mathematically the role of such repeated experience with parasitism in the evolution of egg-ejection by would-be foster parents. Increasing repeated parasitism delayed the evolution of rejection, especially in species that paid higher costs when raising cowbird chicks. These observations help us understand the counterintuitive patterns of non-rejection by vulnerable hosts of parasites.

Why Is Washington Going Easy On Pakistan's Nuclear Black Marketers?, The New Yorker
Excerpt: A Bush Administration intelligence officer with years of experience in nonproliferation issues told me last month, "One thing we do know is that this was not a rogue operation. Suppose Edward Teller had suddenly decided to spread nuclear technology and equipment around the world. Do you really think he could do that without the government knowing? How do you get missiles from North Korea to Pakistan? Do you think A.Q. shipped all the centrifuges by Federal Express? The military has to be involved, at high levels."
Excerpts: Dubai's involvement is no surprise to those who follow the murky world of nuclear technology sales. For the last two decades it, along with other points in the emirates, has been the main hub through which traffickers have routed their illegal commerce to hide their trails. Yet the United States, which has depended on the emirates as a pillar of relative stability in the Middle East and, since 1991, as a host to American troops, has done little to pressure it to crack down on illicit arms trade.
