On The Emergence Of Complex Systems On The Basis Of The Coordination Of Complex Behaviors Of Their Elements, Complexity
Excerpts: (...) The purpose of this article is to challenge the view, often expressed and perhaps prevalent in most discussions, that the essence of complex systems lies in the emergence of complex structures from the non-linear interaction of many simple elements that obey simple rules. Typically, these rules consist only of 0-1 alternatives selected in response to the input received, as in many prototypes like cellular automata, Boolean networks, spin systems, etc. We do not intend to deny that quite intricate patterns and structures can occur in such systems. (...) This brings in a new aspect that seems essential and indispensable to the emergence.
Europe Still Unhappy With U.S. Tax Subsidy, NY Times
Excerpts: The measure (...) was intended to do away with a tax cut for exporters that was declared illegal by the World Trade Organization. Rather than simply outlawing the tax subsidy system, Congress replaced it with three times the number of tax cuts, involving nearly every sector of the economy from tobacco farmers to shipbuilders.(...)
(..) Europeans asked for talks with the United States to question why some of the biggest American corporations should be given a three-year grace period or transition before the original tax cut was ended.
False Friends Are Worse Than Bitter Enemies, Evol. & Human Behav.
Excerpt: One of the most critical features of human society is the pervasiveness of cooperation in social and economic exchanges. Moreover, social scientists have found overwhelming evidence that such cooperative behavior is likely to be directed toward in-group members. We propose that the group-based nature of cooperation includes punishment behavior. Punishment behavior is used to maintain cooperation within systems of social exchange (...) we conducted a gift-giving game experiment with third-party punishment. The results of the experiment (N=90) support the following hypothesis: Participants who are cooperative in a gift-giving game punish noncooperative in-group members more severely than they punish noncooperative out-group members.
Super Searches, Time
Excerpts: IBM's webfountain, a new internet tool, helps companies spot online trends before they emerge.
"We're looking at relationships between entities, and between people and places and products," (...). If a company wants to know, for example, what potential customers are saying online about its new gizmo, or even what people are saying in a specific language about the company's product, WebFountain can help give the answer. In one pilot program, WebFountain found that the buzz on college campuses preceded music sales of new CDs by two weeks (...).
Software Helps Singers Find Perfect Pitch, NPR ME
Excerpts: For those with less-than-perfect singing voices, technology offers help. A number of computer programs can correct pitch to make just about anyone sound in tune -- even NPR's Renee Montagne, who lends her voice to show how the software works.
The technology has become quite prevalent in the music industry, finding its way into many of today's pop recordings -- and some classical ones, as well.
Are Spatial Memories Strengthened In The Human Hippocampus During Slow Wave Sleep?, Evol. & Human Behav.
Excerpt: (...) Here, using regional cerebral blood flow measurements, we show that, in humans, hippocampal areas that are activated during route learning in a virtual town are likewise activated during subsequent slow wave sleep. Most importantly, we found that the amount of hippocampal activity expressed during slow wave sleep positively correlates with the improvement of performance in route retrieval on the next day. These findings suggest that learning-dependent modulation in hippocampal activity during human sleep reflects the offline processing of recent episodic and spatial memory traces, which eventually leads to the plastic changes underlying the subsequent improvement in performance.

Anxiety Good For Memory Recall, Bad For Solving Complex Problems, ScienceDaily
Excerpts: (...) Researchers at Ohio State University gave a battery of simple cognitive tests to 19 first-year medical students one to two days before a regular classroom exam - a period when they would be highly stressed. Students were also given a similar battery of tests a week after the exam, when things were less hectic. While pre-exam stress helped students accurately recall a list of memorized numbers, they did less well on the tests that required them to consider many possibilities in order to come up with a reasonable answer. A week after the exam, the opposite was true. (...)
Psychologist Finds Instance Where 'Two Wrongs Do Make A Right', ScienceDaily
Excerpts: A trusted mental map of your surroundings turns out to be slightly misaligned, skewing your orientation. Your ability to control the direction in which you move is similarly compromised, although in a manner opposite the map's offset. Taken together, the errors cancel one another, and you end up exactly where you want to be. Contrary to the proverb, two wrongs do make a right. This exception is the rule when it comes to how our brain processes what our eyes see and where our body moves, according to a discovery by University of Oregon researchers (...).
A Battle Cry to Decipher Immunity, The Scientist
Excerpts: The march to demystify mammalian immunity has been long and arduous. At the frontlines we face a dizzying array of biochemicals and interactions between multiple cell types aimed at detecting, eliminating, and remembering intruders. (...)
But recent advances in our understanding of innate immunity--that hard-wired, first line of defense that doesn't appear to adapt during infection--have served as a signal flare, rallying those discouraged by the system's complexity. As an initiating factor in the immune response, innate immunity offers an inroad to the entire system.
Cardiovascular Biology: How Genes Know Their Place, Nature
Excerpts: Embryonic development is largely a matter of switching on the right genes, in the right place, and at the right time - it's no use activating heart-manufacturing genes in the limbs, for instance. (...)
Using mice, the authors first discovered that the protein in question, named Baf60c, is initially expressed only in the developing heart. Investigating further, they found that completely eliminating Baf60c from mouse embryos led to major cardiac defects (and early death). Knocking out about 50% of the protein led to somewhat milder, although still ultimately fatal, problems, (...).
Ural Farmers Got Milk Gene First?, Science Now
Excerpts: Less than half of all adults can easily digest milk, a trait believed to have first appeared in people who kept dairy animals. Now scientists have traced the genetic roots of milk tolerance to the Ural mountains, well north of where pastoralism is thought to have begun. The surprising result supports a theory that nomads from the Urals were one of two major farmer groups that spread into Europe, bringing the Indo-European languages that eventually diverged into the world's largest family of modern languages.
Immunology and Olfaction, Science
Excerpts: Immunology and Olfaction Although absent in humans, the vomeronasal organ (VNO) plays a central role in controlling reproductive and social behaviors in most mammals. Vomeronasal sensory neurons detect pheromones and other molecules that carry information about gender, sexual and social status, dominance hierarchy, and individuality, but it has been very difficult to define the molecular nature of these signals. Leinders-Zufall et al. (p. 1033) show that major histocompatibility complex (MHC) class I peptides can activate selective VNO neurons in the basal layer of the VNO.
Making Sense, Nature
Excerpts: Proprioceptors precisely measure physical properties, such as muscle length, tendon tension, joint angle or deep pressure. (...) So proprioception provides information on the physics of the body, (...). The maps derived from these complex calculations not only guide body movement, they also (together with touch) sense the size and shape of objects and measure the geometry of external space. (...)So subjective body consciousness provided by myriad networking proprioceptors is the basis of objective knowledge of fundamental physical properties - space, time and weight - of external reality.

Spider Webs Untangle Evolution, Nature News
The biologist Stephen Jay Gould famously proposed that if we could "rewind the tape" of evolution and play it again, chance would give rise to a world that was completely different from the one we live in now. But the concept that chance reigns supreme may ring less true when it comes to complex behaviours.
Tetragnatha stelarobusta on Maui and T. hawaiensis on the island of Hawaii weave very similar types of web. c PNAS
A study of the similarities between the webs of different spider species in Hawaii provides fresh evidence that behavioural tendencies can actually evolve rather predictably, even in widely separated places.
Supernova Debris Found On Earth, Nature News
Cosmic fallout from an exploding star dusted the Earth about 2.8 million years ago, and may have triggered a change in climate that affected the course of human evolution. The evidence comes from an unusual form of iron that was blasted through space by a supernova before eventually settling into the rocky crust beneath the Pacific Ocean.

The team has now analysed a different piece of ocean crust, where the supernova detritus is concentrated into a clear band of rock that can be accurately dated.
Fish With Cleft Lip Solves Evolution Riddle, Nature News
Excerpts: A 395-million-year-old fish may have answered a pressing question of human evolution: how did our nasal cavities adopt their current layout? The strange specimen has nostrils in the middle of its upper teeth. The fish, called Kenichthys campbelli, represents a halfway point in the evolutionary reshuffling of the nasal passages(...). Most modern fish have four external nostrils, whereas land vertebrates, which are descended from Kenichthys, have nasal passages that form openings near the throat called choanae. The fossil, (...), represents a crucial intermediate step between external nostrils and choanae.
Wandering Nostrils, Nature
Excerpts: An answer (...) now emerges from an ancient fossil fish.
The structures known as choanae may seem obscure. But we've all got them; they are the 'internal nostrils' that form the passage between our nasal cavity and throat that we use for breathing when our mouth is closed. They have also been the subject of much argument among those studying comparative vertebrate anatomy - in particular, the question of how choanae originated in the tetrapods, or land vertebrates, a group that consists of amphibians, reptiles, birds and mammals.

Stickiness Takes On New Shapes, Nature News
Animals such as insects and lizards employ an impressive range of tools to achieve surface-scaling superpowers. The structures they use include everything from flat attachment pads, used by grasshoppers, to microscopic hairs, which cover the feet of geckos.
Was Spiderman's suit covered in tiny doughnuts? c AP PHGOTO/Brian Hendler
But scientists have never had the maths to calculate how well these different shapes perform. Now, new equations enable them to compare different shapes, which could allow us to design artificial surfaces that stick to walls better than anything found in nature, according to researchers
Dynamic Instability of a Bacterial Engine, Science
Excerpts: Bacteria are endowed with a considerable degree of internal organization. Thanks to fluorescence microscopy, it is now clear that many bacterial components--DNA as well as proteins--are found in specific subcellular locations. Indeed, the discovery of prokaryotic homologs of both tubulin and actin, which are key components of eukaryotic cellular organization, has overturned the textbook credo that cytoskeletons are exclusive to eukaryotes . (...)
They show that ParM is a dynamic polymerization engine that drives the segregation of DNA plasmids during bacterial cell division.
Land Management: Forests, Fires And Climate, Nature
Excerpts: In the past 15 years, the western United States has experienced some extreme fires, notable for their size and severity. The annual costs of fire suppression now exceed $1.6 billion, and the ceiling seems nowhere in sight. In the absence of large fires during most of the twentieth century, many forests have become filled with a dense understorey of shrubs and small trees that provide 'ladder fuels' that set the crowns of trees alight: these crown fires are the most destructive types of wildfire.
Biodiversity Effects on Soil Processes Explained by Interspecific Functional Dissimilarity, Science
Excerpts: The relation between species diversity and ecosystem functioning has been keenly debated. (...), the functional dissimilarity of the species in a community may influence the overall functioning of an ecosystem. Heemsbergen et al. (
p. 1019) filled tubes with soil, topped them with alder leaves, and added combinations of different numbers of species of annelids, isopods, and millipedes. They then tracked three "ecosystem function" variables over subsequent weeks. (...) The more dissimilar in function its members, the better the assemblage at decomposing the leaves.
Hide And See, Conflicting Views Of Reef-Fish Colors, Science News
Although the fish may dazzle the human eye with scarlet, rose, yellow, turquoise, emerald, and dozens of other shades, some theorists have proposed that, in the complexity of a reef, the riot of fish colors serves as camouflage. (...)
Popular Hues. Calculations based on fish vision suggest that from a distance yellows blend in with a generic reef background, and the blues fade into vistas of water. A fish among branching corals would be hidden like a soldier wearing camouflage. PhotoDisc
Improvements in cameras and in equipment for analyzing light and color are now inspiring new approaches to approximating a fish-eye view of the reefs. Looking at the abundant coloration from a fishy perspective, the new work demonstrates that people can be quite wrong about what's showy and what's subtle.
Marine Conservation: Sink Or Swim, Nature
Excerpts: Conservation biologists generally agree that unique habitats in the open sea such as hydrothermal vents, seamounts and cold-water reefs require urgent protection. Fishing, pollution and commercial traffic in international waters - known in treaties as the 'high seas' - have increased to such an extent that ecosystems once deemed out of human reach are feeling the effects.
Two years ago, delegates at the World Summit on Sustainable Development in Johannesburg, South Africa, agreed to establish by 2012 a network of marine reserves representing all major habitats, both within and beyond national jurisdiction.
Stealth Now Old Hat - USAF Looks Into Teleportation, Technovelgy.com
The author broke down the various possibilities in this way
("Old School" Teleportation Technology)
- Teleportation - SciFi: the disembodied transport of persons or inanimate objects across space by advanced (futuristic) technological means (adapted from Vaidman, 2001). We will call this sf- Teleportation, which will not be considered further in this study.
- Teleportation - psychic: the conveyance of persons or inanimate objects by psychic means. We will call this p-Teleportation.
- Teleportation - engineering the vacuum or spacetime metric: the conveyance of persons or inanimate objects across space by altering the properties of the spacetime vacuum, or by altering the spacetime metric (geometry). We will call this vm-Teleportation.
- Teleportation - quantum entanglement: the disembodied transport of the quantum state of a system and its correlations across space to another system, where system refers to any single or collective particles of matter or energy such as baryons (protons, neutrons, etc.), leptons (electrons, etc.), photons, atoms, ions, etc. We will call this q-Teleportation.
- Teleportation - exotic: the conveyance of persons or inanimate objects by transport through extra space dimensions or parallel universes. We will call this e-Teleportation.
Editor's Note: This is another example of the power of technical science terms applied to an area where non-experts make funding decisions.
Structured Water Is Changing Models, The Scientist
Large water-molecule clusters may be crucial to cellular processes
Water molecules cluster to form hydrogen-bonded bicyclo-octamers (H2O)8 (top left) that can link together into larger structures (top right). Ideally they form 280-member icosahedral clusters, (H2O)280, (below), shown looking down the two-fold, three-fold, and five-fold axes of symmetry. Only the oxygen atoms of the constituent water molecules are shown (except at top left).
Researchers are beginning to glimpse water's secret social life. Evidence is mounting that water in living systems naturally gathers into frameworks of 14, 17, 21, 196, 280, or more molecules. Some say that the clusters' apparent existence necessitates redesigning simulation models of life processes. And support is growing behind the idea that these intricate structures play key roles in operations ranging from molecular binding to turning on and off basic cell processes.
Biophysics: Water-Repellent Legs Of Water Strider, Nature
Excerpts: Water striders (Gerris remigis) have remarkable non-wetting legs that enable them to stand effortlessly and move quickly on water, a feature believed to be due to a surface-tension effect caused by secreted wax We show here, however, that it is the special hierarchical structure of the legs, which are covered by large numbers of oriented tiny hairs (microsetae) with fine nanogrooves, that is more important in inducing this water resistance.(...)
The maximal supporting force of a single leg is (...) about 15 times the total body weight of the insect.
Community resilience is key to disaster reduction, AlertNet
The correlation between underdevelopment and disasters is made clear in this year's annual World Disasters Report
(...) Why are fewer people dying from disasters even as more people are being affected? This is a question that the World Disasters Report 2004 seeks to answer.
(...) But we present evidence that the knowledge and resilience of people at risk contributes far more to reducing the toll of disasters than many of us in the developed world may expect.
(...)The lesson from Andhra Pradesh is that while authorities and experts can undermine community resilience by offering inappropriate advice, local people often have the knowledge and skills to craft their own recovery. The challenge for aid organisations and governments alike is to understand and nurture these local resources so that community resilience to disasters can flourish.
Cosmic Doomsday Delayed, Nature News

Democratic Values And Citizen Action: A View From US Ninth Graders, Int. J. Edu. Res.
Excerpt: (...) US ninth graders were assessed for their civic knowledge, concepts, attitudes, and experiences. The study yielded information about the development of democratic attitudes and dispositions toward social action. US ninth graders rated free expression and free elections as most important for democracy. They were less sure about the importance of peaceful protests. US ninth graders were above the international average in their support of rights for both women and immigrants. However, not all groups of students were willing to extend rights to "the other." (...) Socio-economic variables and race/ethnicity were related to civic knowledge.
Students' Concepts And Attitudes Toward Citizenship: The Case Of Hong Kong, Int. J. Edu. Res.
Excerpt: This paper analyses the data obtained from the findings on Hong Kong (...). Because the survey was conducted two years after Hong Kong's return to China, the findings reflect concepts and attitudes toward citizenship among Hong Kong students shortly after the change of sovereignty. The study shows that Hong Kong ranks highest in two aspects of citizenship: civic knowledge and attitudes toward immigrants. Hong Kong ranks lowest in attitudes toward the nation, support for women's political rights, confidence in participating at school, and open classroom climate. Moreover, Hong Kong students are most concerned about elections and freedom of expression, (...).
New Standards for Elections, NY Times
Excerpts: The 2004 election may not have an asterisk next to it (...), but the mechanics of our democracy remained badly flawed. From untrustworthy electronic voting machines, to partisan secretaries of state, to outrageously long lines at the polls, the election system was far from what voters are entitled to.
It's patently obvious that presidential elections, at least, should be conducted under uniform rules. Voters in Alaska and Texas should not have different levels of protection when it comes to their right to cast a ballot and have it counted.
You Can Fool Some People Sometimes, arXiv
Abstract: We develop an empirical procedure to qunatify future company performance based on top management promises. We find that the number of future tense sentence occurrences in 10-K reports is significantly negatively correlated with the return as well as with the excess return on the company stock price. We extrapolate the same methodology to US presidential campaigns since 1960 and come to some startling conclusions.
Dick Morris: Exit Polls Were "Juiced", News Hunds
Excerpts: MORRIS: Exit polling is by far the most accurate form of polling. In thirty years I've never seen an exit poll be wrong.
O'REILLY: So you think this was juiced?
MORRIS: Juiced. I use exit pollings in foreign campaigns as a check on the government's count...
O'REILLY (interrupts): Are you accusing ABC News of cooking their poll?
Or, even more interesting, maybe the exit polls were absolutely correct and a whole lot of Kerry votes got destroyed, lost, eaten up or changed by paperless voting machines.

Excerpts: (...) were not anticipating that an investigation would change the outcome of the election.
"But we do want to make sure that where there are problems they're fixed so that it won't affect other elections in the future," Doty said. "We want to make sure that people can be confident in the system."
Doty said, however, that if the GAO does find a lot more problems that haven't yet been reported, then people will at least know about them and be able to decide what to do about them.

Excerpts: The US administration has failed to recognise that Al Qaeda is now a global Islamic insurgency rather than a traditional terrorist organisation, and so poses a different threat than previously believed, (...).
Michael Scheuer, who is also the author of a best-selling book critical of the handling of the fight against terrorism, said in an interview with The New York Times that the government "doesn't respect the threat" because most officials still regard Al Qaeda as a terrorist organisation that can be defeated by arresting or killing its operatives.
U.S. Judge Halts War-Crime Trial at Guantanamo, NY Times
