The 2004 Indian Ocean Earthquake was an undersea megathrust earthquake of moment magnitude 9.0 that struck the Indian Ocean off the western coast of northern Sumatra, Indonesia on December 26, 2004 at 00:58:49 UTC (07:58:49 local time in Jakarta and Bangkok). It was the largest earthquake on Earth since the 9.2-magnitude Good Friday Earthquake which struck Alaska, USA, on March 27, 1964, and the fourth largest since 1900. Tens of thousands were killed by the resulting tsunamis, which were as high as 10 m (33 ft) and struck between 15 minutes and 3 hours after the quake, causing one of the most cataclysmic disasters in modern history.
Some Countries Are Betting That A Few Seconds Can Save Lives, Science
Excerpts: What would you do with 5 to 50 seconds' warning of a major earthquake?
It's not an academic question. Systems that can detect earthquakes near their source and issue warnings before the shaking starts are in place or being deployed in Mexico, Taiwan, and Japan and are being studied for locales from southern California to Istanbul. Enthusiasts are convinced that short-term warnings can save lives by stopping trains before they pass over damaged track, emptying out elevators, and alerting rescue units.
Sounding the Alarm, NY Times
Excerpts: No human power could have stopped the wall of water that washed over low-lying coasts from Indonesia to East Africa on Sunday. But human foresight could, and should, have mitigated the resulting tragedy. As it was, more than 25,000 people lost their lives in the flooding, (...). That death toll could have been cut at least in half if the affected region had had the same kind of international warning network the United States has set up to protect the adjacent Pacific basin.

Collective Intelligence Quanitifed for Computer-Mediated Group Problem Solving, arXiv
Excerpts: Collective Intelligence (CI) is the ability of a group to exhibit greater intelligence than its individual members. Expressed by the common saying that "two minds are better than one," CI has been a topic of interest for social psychology and the information sciences. Computer mediation adds a new element in the form of distributed networks and group support systems. These facilitate highly organized group activities that were all but impossible before computer mediation. This paper presents experimental findings on group problem solving where a distributed software system automatically integrates input from many humans. (...) This study shows that groups can outperform individuals on difficult but not easy problems, though groups are slower to produce solutions.

Abstract: Previous work on the dynamics of bucket brigades has focused on systems in which workers can be ordered with respect to their speeds and where this ordering does not change throughout the line. While this assumption is valid in most environments, it may not be satisfied in some. We consider such environments and explore the conditions under which bucket brigades continue to be effective (compared to a traditional static allocation) with respect to self-balancing behavior and throughput performance. A two worker bucket brigade is studied where one worker is faster than the other over some part of the production line and slower over another part of the line. We analyze the dynamics and throughput of the bucket brigade in two environments with passing and blocking. We present the dynamics of the system in each region of the parameter space and provide insights and operating principles for the implementation and management of the bucket brigades under various scenarios.
Online Games Play With Politics, BBC News Online
Excerpts:
US vote provided the launching platform for political games
|
The ability of games to simulate reality makes them a powerful modelling tool to interact with actual situations in an original way.
"Video games generate strong reactions mainly because they are new, but also because our culture needs to learn how to deal with simulation," Mr Frasca told the BBC News website.
This was the case with the one he created for a political party in Uruguay, Cambiemos, an online puzzle game that offered a view on how the country's problems could be solved by working together.
What Is Good for Children Is Good for Mankind: The Role of Imagination in Discovery, Science
Excerpts: (...) Albert Einstein held that the most beautiful thing we can experience is the mysterious, and called it "the source of all true art and science." That thought, in turn, leads naturally into what I take as my main theme here: the role of the imagination in scientific discovery. As scientists we are all steeped in the "scientific method" of problem solving, with its framing of hypotheses, testing, and reproducible observations. But the entire enterprise must start with imagination if it is new knowledge we are after.
Singapore Leads, U.S. Lags in Science, Math Student Achievement, Science
Excerpts: Singaporean students lead the world in math and science, according to the latest international comparison of student performance. Educators say that the top ranking, among elementary and middle school students from as many as 49 countries, also demonstrates how a nation's commitment to excellence can pay off fairly quickly.
(...) Singapore had excelled in two previous studies, but this time its fourth graders rose from fifth to first place in science after education officials revamped the small island nation's curriculum and strengthened teacher training.
The Concept Of 'Developing The Brain': A New Natural Science For Learning And Education, Brain & Dev.
Excerpt: From the viewpoint of biology, learning and education can be defined as the processes of forming neuronal connections in response to external environmental stimuli, and of controlling or adding appropriate stimuli, respectively. Learning and education can thus be studied as a new field of natural sciences with the entire human life span as its subject, thus including various problems such as fetal environment, childcare, language acquisition, general/special education, and rehabilitation. Non-invasive imaging of higher-order brain functions in humans will clarify the brain's developmental processes, and will provide various evidence for learning sciences. This new approach is called 'developing the brain' (...).
Infants, Children Prefer Sounds Over Pictures And Only Slowly Become Visually Oriented, ScienceDaily
Excerpts: New research provides the strongest evidence to date that infants and young children - unlike adults -- are more drawn to sounds than they are to visuals in their environment. In fact, when 4-year-olds are presented with sounds and pictures at the same time and told to pay particular attention to the pictures, they can't - the sounds dominate their attention. "We found that sounds are dominant over visuals from infancy, and only slowly through childhood do visuals become more important," (...) "The younger the children are, the more dominant their auditory system seems to be." (...)
The Evolution of Imitation and Mirror Neurons in Adaptive Agents, Cognitive Systems Research
Excerpts: Imitation is a highly complex cognitive process, involving vision, perception, representation, memory and motor control. The underlying mechanisms that give rise to imitative behavior have attracted a lot of attention in recent years and have been the subject of research in various disciplines, from neuroscience to animal behavior and human psychology. In particular, studies in monkeys and humans have discovered a neural mirror system that demonstrates an internal correlation between the representations of perceptual and motor functionalities. (...) Interestingly, these agents are found to include a neural "mirror" device analogous to those identified in biological systems.
Human Altruism: Economic, Neural, And Evolutionary Perspectives, Current Opin. Neurobiol.
Excerpt: Human cooperation represents a spectacular outlier in the animal world. Unlike other creatures, humans frequently cooperate with genetically unrelated strangers, often in large groups, with people they will never meet again, and when reputation gains are small or absent. Experimental evidence and evolutionary models suggest that strong reciprocity, the behavioral propensity for altruistic punishment and altruistic rewarding, is of key importance for human cooperation. Here, we review both evidence documenting altruistic punishment and altruistic cooperation and recent brain imaging studies that combine the powerful tools of behavioral game theory with neuroimaging techniques.

Quantifying The Complexity Of Chaos Of Molecular Systems, Complexity
Abstract: The simulated classical dynamics of a small molecule exhibiting self-organizing behavior via a fast transition between two states is analyzed by calculation of the statistical complexity of the system. It is shown that the complexity of molecular descriptors such as atom coordinates and dihedral angles have different values before and after the transition. This provides a new tool to identify metastable states during molecular self-organization. The highly concerted collective motion of the molecule is revealed. Low-dimensional subspaces dynamics is found sensitive to the processes in the whole, high-dimensional phase space of the system.
Natural Selection Acts On The Quantum World, Nature News
Excerpts: If, as quantum mechanics says, observing the world tends to change it, how is it that we can agree on anything at all? Why doesn't each person leave a slightly different version of the world for the next person to find?
Because, say the researchers, certain special states of a system are promoted above others by a quantum form of natural selection, which they call quantum darwinism. (...)
If it wasn't for quantum darwinism, (...) the world would be very unpredictable: different people might see very different versions of it.
Taming the Hyperbolic Jungle by Pruning Its Unruly Edges, Science
Excerpts: Suppose you stand in a room with perfectly reflecting mirrors--what would you see? (...) With four [cylindrical, Ed. ] mirrors, depending on their size and arrangement, you might get a circle, or you might get a jagged, contorted figure that defied Klein's attempts to draw it. Klein was born a century too early to see such figures--now called fractals-(...). You can think of these fractals as being drawn on the "sphere at infinity," the canvas at the end of the universe.
China in Line as U.S. Rival for Canada Oil, NY Times
Excerpts: Chinese energy companies are on the verge of striking ambitious deals in Canada in efforts to win access to some of the most prized oil reserves in North America.
The deals may create unease for the first time since the 1970's in the traditionally smooth energy relationship between the United States and Canada.
Canada, the largest source of imported oil for the United States, has historically sent almost all its exports of oil south by pipeline to help quench America's thirst for energy.

UV camera aboard small satellite catches glimpse of nearby, newborn
Galaxies
The Galaxy Evolution Explorer (GALEX) has returned snapshots of several dozen newborn galaxies, (...). Remarkably, these objects are nearby, not many billions of light-years away as all other known baby galaxies are. This closeness will give scientists a brand new way to study how galaxies formed.
Astronomers have long known that most galaxies coalesced when the universe was young; their birthrate peaked about five billion to ten billion years ago and has been declining ever since.
New Juggling Tricks Created By Maths, New Scientist
Excerpts: Over the past two decades, enthusiasts have developed a theory of juggling that has allowed them to invent many different new ways to juggle. (...), they are now even exploring what happens when jugglers throw not in patterns, but randomly - (...).
Juggling maths took off in 1985, when several mathematically inclined jugglers came up with a notation for juggling patterns, called "site swap notation". Until then, jugglers had shared new tricks by demonstration, but site swap notation made it possible to write down a trick (...).
'Eye In The Sky' Watches Over Air, BBC
Excerpts: The air around us seems abundant from Earth. But from space, our endless blue sky is only a thin shield around a massive planet. (...)
In orbit since July to monitor ozone, climate change and air quality, the US space agency's (Nasa) Aura satellite has already produced the first direct measurements of lower atmospheric - tropospheric - ozone from space, including chemicals that are a precursor to "bad ozone" at ground level,(...).
It has also provided new images of the ozone hole over Antarctica.
Pacemaker Neurons And Neuronal Networks: An Integrative View, Current Opin. Neurobiol.
Excerpts: Rhythmically active neuronal networks give rise to rhythmic motor activities but also to seemingly non-rhythmic behaviors such as sleep, arousal, addiction, memory and cognition. Many of these networks contain pacemaker neurons. The ability of these neurons to generate bursts of activity intrinsically lies in voltage- and time-dependent ion fluxes resulting from a dynamic interplay among ion channels, second messenger pathways and intracellular Ca2+ concentrations (...). This complex intrinsic and extrinsic modulation of pacemaker activity exerts a dynamic effect on network activity. The nonlinearity of bursting activity might enable pacemaker neurons to facilitate the onset of excitatory states or to synchronize neuronal ensembles (...).

When Genes Are Out of the Loop, Science Now
Excerpts: A defective protein has long been suspected in helping trigger Rett syndrome, a neurological disorder that strikes girls and is characterized by autistic-like behaviors, severe loss of motor control, breathing irregularities, and bone problems. Now scientists have discovered that, at least in mice, the pernicious protein may fail in its task of helping to loop a stretch of DNA, altering activity of another key protein.
In girls afflicted with Rett syndrome, symptoms usually emerge after about 18 months of seemingly normal development.
New Enzyme is a Turnoff for Genes, Science Now
Excerpts:  Mission accomplished. Scientists have finally found an enzyme acting as a demethylator. Credit: Science |
Buried deep inside a cell's nucleus, a genetic switch hunted by biologists for decades has finally been identified. The finding could reveal much about how cells control gene activity, and also illuminate cancer, multiple sclerosis, and other diseases spurred by faulty gene expression.
The newly discovered enzyme acts upon histones, the specialized proteins that strands of DNA loop around. (...) seen as active cogs in a cell's gene regulation machinery. It's well known, for example, that certain enzymes can add methyl groups to histones, which turns genes either on or off.
Toward a Systems Approach to Understanding Plant Cell Walls, Science
Abstract: One of the defining features of plants is a body plan based on the physical properties of cell walls. Structural analyses of the polysaccharide components, combined with high-resolution imaging, have provided the basis for much of the current understanding of cell walls. The application of genetic methods has begun to provide new insights into how walls are made, how they are controlled, and how they function. However, progress in integrating biophysical, developmental, and genetic information into a useful model will require a system-based approach.

Excerpts: Non-human primates were thought to have vocal tracts resembling simple tubes incapable of sophisticated articulation.
But a British-US-German team reports in the Journal of Human Evolution that the alarm calls of Diana monkeys would be impossible without a complex tract.
It says the finding may shed light on how and when human speech evolved.
It is possible that some of the proto-structures in the throat required for talking were already present in our primate ancestors millions of years ago, the researchers argue.

 Off-color. The loss of stem cells turns mice grey. Credit: Emi K. Nishimura And David E. Fisher |
Hair goes gray after losing the stem cells that replenish pigment cells
When the team looked in normal old mice, they saw the same, misplaced melanocytes cells taking up the space that stem cells vacated. And when they turned to humans, they discovered misplaced melanocytes in middle-aged people. Moreover, the elderly had neither stem cells nor melanocytes. That suggests the mechanism behind hair color loss is similar in mice and humans.
"The work is telling us that these [melanocyte] stem cells don't have an infinite capacity for self-renewal," (...).

Excerpts:
 Food value. With a rich diet, male Teleogryllus commodus crickets invest more in sex and die younger. Credit: John Hunt |
Being attractive as a male animal-(...)--often comes at a cost that only the fittest individuals can bear. That may be why several studies have found that animals that are good at luring mates also live longer than others. (...) the opposite is sometimes true as well. "High-quality males," as biologists call them, may sometimes invest so much in wooing members of the opposite sex that they use up their energy and die earlier than their inferior counterparts. That hypothesis holds true for the field cricket, (...).
Ecological Versus Climatic Thresholds, Science
Excerpts: How will the terrestrial vegetation respond to future climate change? (...) show that ecological or vegetation responses to climatic changes may be delayed if an ecological threshold has to be crossed. In another study, Tzedakis et al. show that once such a threshold is crossed, the vegetation may not necessarily recover with a return to the original climatic conditions. Thus, both the time scale and the reversibility of future ecological changes as a result of global warming remain unclear.
Asynchronous Terrestrial and Marine Signals of Climate Change During Heinrich Events, Science
Excerpts: This asynchrony between land and ocean records reveals that the duration of terrestrial interglacial periods cannot be fit into any particular pattern and that processes that produce millennial-scale climate variability are important determinants of the duration of warm interglacials. Both marine and terrestrial records are commonly used for climate reconstructions, and while it is fairly easy to generate precise records, establishing a common chronology for these two different types of records is much more difficult.
(...) terrestrial changes can lag marine changes by 1000 to 2000 years.
Microbial Life Breathes Deep, Science
Excerpts: The apparent paucity of deep-sea biota led the 19th-century biologist Edward Forbes to question the very existence of life at depths greater than 550 m. Subsequent oceanographic expeditions soon laid Forbes' "azoic theory" to rest, with discoveries of a diverse and abundant marine fauna flourishing in the greatest depths of the oceans. In parallel ways, contemporary microbial surveys are expanding the range of known habitats where microbial life thrives. (...) evidence for metabolically diverse and active microbial communities buried deep within marine sediments nearly 0.5 km below the seafloor (...).

Abstract: The soil-microbe system is one of the most diverse components of the terrestrial ecosystem. The origin of this diversity, and its relation to the life-sustaining processes that are mediated by the resident microbial community, is still poorly understood. The inherent complexities necessitate a theoretical framework that integrates ecological and evolutionary approaches and which embraces the physical heterogeneity of the soil environment. Such a framework is currently lacking, although recent advances in theory and experimentation are beginning to identify the essential ingredients. Here, we review and evaluate the relevance of current modelling approaches, and propose a new synthesis of an evolutionary ecology of life in soil. Key elements include an account of dispersal, horizontal gene transfer, and the consideration of the physical and biological components of soil as an integrated complex adaptive system.
Foraging In A Complex Environment: From Foraging Strategies To Emergent Spatial Properties, Ecol. Complexity
Excerpt: Spatial interactions between herbivores and vegetation resources drive plant and animal dynamics and ecosystem functioning. Energy maximization is often proposed as an important factor determining diet selection, however, few studies have made the link between different energy-maximizing strategies and emergent properties, such as the spatial pattern of defoliation. Using an individual-based model, we investigate the role of several hypothetical perceptual traits in the formation of defoliation patterns and the consequences for the foraging performance of the animals. Results suggest that in complex mosaics of poor quality vegetation, highly perceptual strategies are not necessarily an advantage, (...).

Excerpt: Conventional physics is of little help in describing how ecosystems develop. Imbalances in material and energy usually equilibrate at rates that are much faster than changes in the internal structural constraints occur. Quantifying and following these internal constraints, therefore, constitutes the primary task for those who would describe ecodynamics. Many of the internal constraints link the biotic elements that constitute the ecosystem, and such connections often form self-entailing cycles. The combination of contingent behavior with auto-referential constraints engenders decidedly non-mechanical behaviors in ecosystems. It is impossible to treat explicitly all the hidden constraints in an ecosystem, (...).

Use of Logic Relationships to Decipher Protein Network Organization, Science
Excerpts: A major focus of genome research is to decipher the networks of molecular interactions that underlie cellular function. (...). Logic analysis (...) identifies triplets of proteins whose presence or absence obey certain logic relationships. For example, protein C may be present in a genome only if proteins A and B are both present. The method reveals many previously unidentified higher order relationships. These relationships illustrate the complexities that arise in cellular networks because of branching and alternate pathways, and they also facilitate assignment of cellular functions to uncharacterized proteins.
Peptide Signals Sense and Destroy Target Cells, Science
Excerpts: Bacteria are not isolated solitary organisms, but actively "speak" to one another by sending and receiving transmissions in the form of chemical signals. In a process called "quorum sensing," bacteria measure the concentration of these signaling molecules in order to assess the size of the bacterial population. Once a "quorum" is reached, certain biological programs--such as sporulation, or the production of light, biofilms or virulence factors, depending on the species and context--are activated synchronously throughout the population. (...) also for direct detection of eukaryotic target cells.
Enterococcus faecalis Senses Target Cells and in Response Expresses Cytolysin, Science
Excerpts: Many virulent strains of Enterococcus faecalis produce a two-subunit toxin, termed cytolysin. Cytolysin expression is regulated by one of the subunits (CylLS'') through a quorum-sensing autoinduction mechanism. (...) When target cells are present, however, CylLL'' binds preferentially to the target, allowing free CylLS'' to accumulate above the induction threshold. Thus, enterococci use CylLL'' to actively probe the environment for target cells, and when target cells are detected, allows the organism to express high levels of cytolysin in response.
Selecting The Signals For A Brain-Machine Interface, Current Opin. Neurobiol.
Excerpts: Brain-machine interfaces are being developed to assist paralyzed patients by enabling them to operate machines with recordings of their own neural activity. Recent studies show that motor parameters, such as hand trajectory, and cognitive parameters, such as the goal and predicted value of an action, can be decoded from the recorded activity to provide control signals. Neural prosthetics that use simultaneously a variety of cognitive and motor signals can maximize the ability of patients to communicate (...). Although most studies have recorded electroencephalograms or spike activity, recent research shows that local field potentials (LFPs) offer a promising additional signal. (...)

A recently rediscovered 400-meter Near-Earth Asteroid (NEA) is predicted to pass near the Earth on 13 April 2029. The flyby distance is uncertain and an Earth impact cannot yet be ruled out. The odds of impact, presently around 1 in 300, are unusual enough to merit special monitoring by astronomers, but should not be of public concern. These odds are likely to change on a day-to-day basis as new data are received. In all likelihood, the possibility of impact will eventually be eliminated as the asteroid continues to be tracked by astronomers around the world.
Complex Challenges: Global Terroist Networks
Jet Is an Open Secret in Terror War, Washington Post
Excerpts: The plane's owner of record, Premier Executive Transport Services Inc., lists directors and officers who appear to exist only on paper. (...)
In this case, the agency is flying captured terrorist suspects from one country to another for detention and interrogation.
The CIA calls this activity "rendition." (...)
Since Sept. 11, 2001, secret renditions have become a principal weapon in the CIA's arsenal against suspected al Qaeda terrorists, (...). But as the practice has grown, the agency has had significantly more difficulty keeping it secret.
Heightened Security or Neocolonial Science?, Science
Excerpts: The stepped-up regulations are the latest example of the clash between scientists' cherished ways of doing business and the urgent need to reduce the potential for bioterrorism, and some researchers say the rules make sense. (...)
But others fear that the tightened security could stifle cooperation. (...) "By inhibiting research on the ecology and epidemiology of potential biological weapons in their natural settings overseas, we will be less prepared to respond optimally to the introduction of these agents by a terrorist."
