Net Heads - Huge Numbers Of Brain Cells May Navigate Small Worlds, Science News
About 40 years ago, the late psychologist Stanley Milgram tapped into the commonsense notion that "it's a small world." Milgram asked 60 people to send a folder to a certain individual whom none of them knew. Participants were given a little information about the target person and asked to mail the folder to a friend or acquaintance who, in their view, was more likely to know the stranger than they were. Each recipient of the folder was asked to do the same, until the material reached its destination.

While You Slumber, Your Brain Puts The World In Order, NewScientist.com
Excerpts: It seems that as well as strengthening our memories, sleep also helps us to extract themes and rules from the masses of information we soak up during the day. (...)
In another experiment, people were shown cards with symbols followed by reports of various weather outcomes - so for example, diamond shapes might be followed by rain 70 per cent of the time. Twelve hours after training, people felt able to guess the weather from the symbols, though they struggled to voice their "rules". After sleeping, their predictions were 10 per cent better.
Brain Creates 'New' Nerve Cells, BBC News
Researchers have discovered a type of brain cell that continuously regenerates in humans. A pool of "resting cells" migrate to create new nerve cells in the part of the brain which deals with smell. The system has been shown in mice and rats but it was believed it did not exist in the human brain. (...)
A store of regenerating cells has been found in the human brain
Experts said the findings could be important for future research into brain cell repair in patients with neurodegenerative diseases such as Alzheimer's disease and, importantly, that studies in mice would be applicable to humans.
Connections - Collective Minds, Nature
Excerpts: By tapping into social cues, individuals in a group may gain access to higher-order computational capacities that mirror the group's responses to its environment. (...)
We are beginning to comprehend more fully how individuals in groups can gain access to higher-order collective computational capabilities such as the simultaneous acquisition and processing of information from widely distributed sources. (...) Thus, like the brain, groups may adapt to compute 'the right thing' in different contexts, matching their collective information-strategy with the statistical properties of their environment.
Make Room, Wikipedia: Internet-based Collaboration Could Change the Way We Do Business, Knowledge@Wharton
Excerpts: "The national intelligence community took a lot of criticism after 9/11 for failing to connect the dots," (...). "And so now the national intelligence community is saying, 'Well, could we learn something from Wikipedia, and could we share knowledge in a cross-organizational way?' And in fact we have IntelliPedia, which is actually a real project. Of course, it's not open to the public." (...)
(...) rapidly surging online creation and collaboration in the mode of Wikipedia will "open up the economy" and revolutionize the way that business is conducted in the 21st century.
Key Biology Databases Go Wiki, Nature
Excerpts: Collaborative approach aims to keep pace with discoveries.
Barend Mons's first objective would be ambitious enough for most people: to meld some of the most important biomedical databases into a single information resource. But that's just the beginning. Mons, a bioinformatician at the Erasmus Medical Centre in Rotterdam, the Netherlands, also wants to apply the Wikipedia philosophy. He's inviting the whole research community to help update a vast store of interlinked data.
Socionics: Sociological Concepts for Social Systems of Artificial (and Human) Agents, JASSS
Abstract: Socionics is an interdisciplinary approach with the objective to use sociological knowledge about the structures, mechanisms and processes of social interaction and social communication as a source of inspiration for the development of multi-agent systems, both for the purposes of engineering applications and of social theory construction and social simulation. The approach has been spelled out from 1998 on within the Socionics priority program funded by the German National research foundation. This special issue of the JASSS presents research results from five interdisciplinary projects of the Socionics program. The introduction gives an overview over the basic ideas of the Socionics approach and summarizes the work of these projects.
Washington's $8 Billion Shadow, Vanity Fair
Excerpts: SAIC (Science Applications International Corporation, Ed.) has been awarded more individual government contracts than any other private company in America. (...)
SAIC's friends in Washington are everywhere, and play on all sides; the connections are tightly interlocked. To cite just one example: Robert M. Gates, the new secretary of defense, whose confirmation hearings lasted all of a day, is a former member of SAIC's board of directors. In recent years the company has obviously made many missteps, and yet SAIC's influence in Washington seems only to grow, impervious to business setbacks or even to a stunning breach of security.
Editor's Note: More and more government functions are outsourced to private companies whose employees and directors form a complex network with government agencies.
The Largest Government Contractor You've Never Heard Of, WNYC
Excerpts: In "Washington's $8 Billion Shadow", Pulitzer Prize-winning Vanity Fair contributing editors Don Barlett and Jim Steele take us behind the scenes of SAIC (the Science Applications International Corporation), which has been awarded more individual government contracts than any other private company in America. They explain that although you've probably never heard of SAIC, it's bigger than the departments of Labor, Energy, and Housing and Urban Development combined, and has a huge impact on all our lives.
Politics and Science: Chalk and Cheese?, BBC News
Excerpt: Motivated by my own experience of the civil service tendency to hold things close to the chest, one of the first things I did after becoming chief scientific adviser was to set out formal guidelines for handling science advice in policy making. Further developed by my successor, Sir David King, these guidelines say:
* in any scientific issue, seek advice widely, deliberately including dissenting views
* do it all openly
* frankly acknowledge uncertainty
* try to manage potential risks in a proportionate manner, offering choice whenever possible (...)
Bush and the Psychology of Incompetent Decisions, truthout
Excerpts: President George W. Bush prides himself on "making tough decisions." But many are sensing something seriously troubling, even psychologically unbalanced, about the president as a decision-maker. They are right.
Because of a psychological dynamic swirling around deeply hidden feelings of inadequacy, the president has been driven to make increasingly incompetent and risky decisions. This dynamic makes the psychological stakes for him now unimaginably high. The words "success" and "failure" have seized his rhetoric like metaphors for his psyche's survival.
How Not to Talk to Your Kids - The Inverse Power of Praise., New York Magazine
(...) Dweck discovered that those who think that innate intelligence is the key to success begin to discount the importance of effort. I am smart, the kids' reasoning goes; I don't need to put out effort. Expending effort becomes stigmatized - it's public proof that you can't cut it on your natural gifts.
(Photo: Phillip Toledano; styling by Marie Blomquist for I Group; prop styling by Anne Koch; hair by Kristan Serafino for L'Oreal Professionnel; makeup by Viktorija Bowers for City Artists; clothing by Petit Bateau [shirt and pants])
Repeating her experiments, Dweck found this effect of praise on performance held true for students of every socioeconomic class. It hit both boys and girls - the very brightest girls especially (they collapsed the most following failure).
Po Bronson: The Problem with Praise, WBUR.org
Excerpts: In recent years, the self-esteem movement born in the 1960s has run into some serious opposition when it comes to scholars who think about raising kids. You think telling young sons and daughters they're brilliant, wondrous, smart, smart, smart is a gift? Maybe not. Newer research suggests that encouraging kids to strive, to try, to grow is the way to really fire up their engines. That a shower of praise can be paralyzing.

The Architecture Of Human Kin Detection, Nature
Excerpts: Evolved mechanisms for assessing genetic relatedness have been found in many species, but their existence in humans has been a matter of controversy. Here we report three converging lines of evidence, drawn from siblings, that support the hypothesis that kin detection mechanisms exist in humans. These operate by computing, for each familiar individual, a unitary regulatory variable (the kinship index) that corresponds to a pairwise estimate of genetic relatedness between self and other.
Socially Intelligent Robots: Dimensions Of Human-Robot Interaction, Phil. Tran. Biol. Sc.
Excerpt: Social intelligence in robots has a quite recent history in artificial intelligence and robotics. However, it has become increasingly apparent that social and interactive skills are necessary requirements in many application areas and contexts where robots need to interact and collaborate with other robots or humans. Research on human-robot interaction (HRI) poses many challenges regarding the nature of interactivity and 'social behaviour' in robot and humans. The first part of this paper addresses dimensions of HRI, discussing requirements on social skills for robots and introducing the conceptual space of HRI studies. (...)
Neuroscience: Where Am I?, Science
Excerpts: The Greek philosopher Heraclitus famously observed, "You can never step into the same river; for new waters are always flowing on to you." How do we recognize a place as the same, even when it is different? How do brains routinely activate the same representations in response to somewhat different experiences? When is experience the same but different, and when is it just plain different?
Neuroscientists are getting closer to obtaining answers by recording the activity of neurons in the rat hippocampus that signal the animal's location.
More Than Meets The Tongue: Color Of A Drink Can Fool The Taste Buds Into Thinking It Is Sweeter, ScienceDaily
Excerpts: Does orange juice taste sweeter if it's a brighter orange? A new study in the March issue of the Journal of Consumer Research finds that the color of a drink can influence how we think it tastes. In fact, the researchers found that color was more of an influence on how taste was perceived than quality or price information. "Perceptual discrimination is fundamental to rational choice in many product categories yet rarely examined in consumer research," write JoAndrea Hoegg (...). "The present research investigates discrimination as it pertains to consumers' ability to identify difference--or the lack thereof--among gustatory stimuli."
Largest Genomic Search Finds Genes That May Contribute To Autism, Science Daily
Excerpts: The largest search for autism genes to date, funded in part by the National Institutes of Health (NIH), has implicated components of the brain's glutamate chemical messenger system and a previously overlooked site on chromosome 11. Based on 1,168 families with at least two affected members, the genome scan adds to evidence that tiny, rare variations in genes may heighten risk for autism spectrum disorders (ASD)*.
Lab-Grown Replacement Teeth Fill The Gap, NewScientist.com
Excerpts: Takashi Tsuji at the Tokyo University of Science, Japan, and his colleagues took single-tooth mesenchymal and epithelial cells - the two cell types that develop into a tooth - from mouse embryos. They stimulated these cells to multiply before injecting them into a drop of collagen gel. Within days, the cells formed tooth buds - the early stage of normal tooth formation.
The team then transplanted these tooth buds into cavities left after they had extracted teeth from adult mice.
Excerpts: Researchers are finding ways to use stem cells to regrow teeth--a potentially easier and healthier alternative to dentures and dental implants. (...)
The researchers were able to transplant the tooth into an adult mouse, and the tooth bud continued to grow to full size.
Teeth in mice, much like those in humans, form during embryonic development from two major cell types: epithelial and mesenchymal. Epithelial cells give rise to the outer enamel, while mesenchymal cells form a tooth's inner connective tissue and blood vessels.
Surgeons Who Play Video Games More Skilled - U.S. Study, Reuters
Excerpts: There was a strong correlation between video game skills and a surgeon's capabilities performing laparoscopic surgery (...).
Laparoscopy and related surgeries involve manipulating instruments through a small incision or body opening where the surgeon's movements are guided by watching a television screen.
Video game skills translated into higher scores on a day-and-half-long surgical skills test, and the correlation was much higher than the surgeon's length of training or prior experience in laparoscopic surgery, the study said.
Bacterium Battles Against The Current, Physicsweb.org
The bacterium E. coli has an unusual ability to swim upstream, according to experiments performed in the US and Turkey. By creating tiny microfluidic channels similar to blood vessels, physicists found that the bacterium's ability derives from an innate tendency to swim to the left at surfaces, enabling it to locate flow regimes more favourable to upstream swimming. They now say that the ability could be fundamental to the transport of certain infections (Phys. Rev. Lett. 98 068101).
An E. Coli bacterium has two to six flagella, which form a bundle and propel the cell forward when rotated. Now, Jane Hill and colleagues from Yale University in the US and Bogazici University in Turkey have discovered that, in the right circumstances, this propulsion is strong enough to lead the bacterium upstream.

Maplike Representation of Celestial E-Vector Orientations in the Brain of an Insect, Science
Excerpts: The orientation of polarized light is represented as a columnar map in the locust brain, which may help to orient the insect under the open sky.
For many insects, the polarization pattern of the blue sky serves as a compass cue for spatial navigation. E-vector orientations are detected by photoreceptors in a dorsal rim area of the eye. Polarized-light signals from both eyes are finally integrated in the central complex, a brain area consisting of two subunits, the protocerebral bridge and the central body.
Is There A Pilot In The Insect?, ScienceDaily
Excerpts: When they fly, insects use their vision for piloting, just like human pilots. The electric signals from their facetted eyes travel through specialized neurons to stimulate the wing muscles, which let the insects correct their flight and avoid crashes. Could these same neurons be used in a sort of "automatic pilot"? (...) have revealed an automatic mechanism called the "optic flow regulator" that controls the lift force. The researchers obtained these results by modeling the overland flight navigation of insects using experiments carried out on OCTAVE, a captive flying robot microhelicopter that can reproduce much of the mysterious natural insect behavior. (...)
Chimpanzee Stone Age: Finds In Africa Rock Prehistory Of Tools, Science News
Working along a riverbank in a West African rain forest, researchers have uncovered remnants from a chimpanzee stone age that started at least 4,300 years ago. The finds constitute the only evidence yet detected of prehistoric ape behavior.
NUTCRACKER SWEET. At a site in West Africa, a stone used by chimps to hammer open nuts around 4,300 years ago lies next to an excavator's trowel. Univ. of Calgary
Most of the more than 200 stone artifacts found at three sites in Ta? National Park, Ivory Coast, were used by prehistoric chimps to crack open nuts, say archaeologist Julio Mercader of the University of Calgary in Alberta and his colleagues.
Food Chains: Killer In The Kelp, Nature
Excerpts: Could a change in the dining habits of orcas crash an ecosystem?
An abiding mystery, though, is whether a change from one feeding habit to another could profoundly alter the balance of marine ecosystems. In 1998, a team led by marine ecologist Jim Estes at the University of California, Santa Cruz, proposed that just such a shift might explain an enigmatic and precipitous decline in Western Alaska's population of sea otters (Enhydra lutris)1.
Fake Fruits Could Help Restore Rainforest, News@Nature
Bats can be lured into large areas of destroyed rainforest with fake fruits, researchers have found. This, they say, could be the key to restoring patchy parts of the landscape. South American leaf-nosed bats of the family Phyllostomidae defaecate the seeds of the fruits they have eaten as they fly. This process, known as 'seed rain', aids plant dispersal throughout the rainforest. (...)

Dolphin Social Intelligence: Complex Alliance Relationships In Bottlenose Dolphins, Phil. Tran. Biol. Sc.
Excerpts: Bottlenose dolphins in Shark Bay, Australia, live in a large, unbounded society with a fission-fusion grouping pattern. Potential cognitive demands include the need to develop social strategies involving the recognition of a large number of individuals and their relationships with others. Patterns of alliance affiliation among males may be more complex than are currently known for any non-human, with individuals participating in 2-3 levels of shifting alliances. (...) In general, selection for social intelligence in the context of shifting alliances will depend on the extent to which there are strategic options and risk. (...)
Conservation Biology: The Diversity Of Biodiversity, Nature
Excerpts: Species richness is not the same as evolutionary richness. So which is the better measure for setting conservation priorities? The flora of the Cape of South Africa provides a test for that pressing question.
The Wealth Of Species: Ecological Communities, Complex Systems And The Legacy Of Frank Preston, Ecol. Lett.
Excerpts: General statistical patterns in community ecology have attracted considerable recent debate. Difficulties in discriminating among mathematical models and the ecological mechanisms underlying them are likely related to a phenomenon first described by Frank Preston. (...) We provide additional examples to show that four different 'distributions of wealth' (species abundance distributions, species-area and species-time relations, and distance decay of compositional similarity) are not unique to ecology, but have analogues in other physical, geological, economic and cultural systems. Because these appear to be general statistical patterns characteristic of many complex dynamical systems they are likely not generated by uniquely ecological mechanistic processes.
What Recognizes What In Plant Disease Resistance?, Innovations-report
Excerpts: Plants have an immune system that resists infection, yet 10% of the world's agricultural production is lost annually to diseases caused by bacteria, fungi, and viruses. Understanding how disease resistance works may help combat this scourge. (...) show how one aspect of the plant immune system is defined by the gene-for-gene hypothesis: a plant Resistance (R) gene encodes a protein that specifically recognizes and protects against one pathogen or strain of a pathogen carrying a corresponding Avirulence (Avr) gene. (...) These findings provide novel insights into how R proteins recognize pathogen Avr proteins and should help in long-term efforts to enhance crop yield. (...)
Stroke Of Good Fortune: A Wealth Of Data From Petrified Lightning, Science News
The ratios of elements in fulgurite's gases were typical of those in the modern soils of that region.
Bolt From The Blue. When lightning strikes the ground, it fuses sand in the soil into tubular masses of glass called fulgurites (top). The gases trapped in bubbles in that glass (bottom) yield clues to ancient soil and atmospheric chemistry and climate. L. Carion/Carion Minerals, Paris; Navarro-Gonz?lez
All these clues suggest that 15,000 years ago, near the end of the most recent ice age, the climate in southwestern Egypt was similar to that found today in Niger.
Because fulgurites are mainly glass, they're chemically stable and aren't very susceptible to erosion, says Barbara Sponholz, a physical geographer at the University of W?rzburg in Germany. That makes fulgurites and the gases that they contain long-lasting indicators of climate, she notes.

Nanofluidics: Silicon For The Perfect Membrane, Nature
Excerpts: Newly developed ultrathin silicon membranes can filter and separate molecules much more effectively than conventional polymer membranes. Many applications, of economic and medical significance, stand to benefit.
Excerpts: By measuring nanoscale forces, researchers learn to make lithium-ion batteries that pull themselves together.
Researchers at MIT have designed a rechargeable lithium-ion battery that assembles itself out of microscopic materials. This could lead to ultrasmall power sources for sensors and micromachines the size of the head of a pin. It could also make it possible to pack battery materials in unused space inside electronic devices.
To Add Speed, Chipmakers Tune Structure, Business Week
Excerpts: IBM, Intel, and AMD are finding ways around the physical problems that have hampered their efforts to make chips faster, (...)
By embedding DRAM directly onto the processor, IBM will be able to eliminate another type of memory that's usually embedded onto a processor called SRAM, or static random access memory, which is typically faster than DRAM, and acts as a go-between between the DRAM and the processor. However, SRAM takes up a lot of space on a processor, and with chips getting smaller all the time, the change frees up a lot of valuable space.
Magnet Misbehaves Near Absolute Zero, Physicsweb.org
Excerpts: The strange behaviour of a magnet near absolute zero temperature provides the first direct evidence that some quantum phase transitions proceed very differently than the conventional phase transitions that occur at higher temperatures. Researchers in Germany applied a magnetic field to a metallic compound and watched it transform from a magnet to a non-magnet -- just as expected. The surprise came at higher field strengths, where a puzzling change in the character of the metal was observed.
Quantum Mechanics: The Truth About Reality, Nature
Excerpts: Hopes of keeping quantum mechanics 'real' have been dashed by new measurements of neutrons' quantum behaviour. Despite what our classical sensibilities require, the world is indeed fundamentally random.
Dark Energy: Seeking The Heart Of Darkness, New Scientist
Excerpts: Perhaps the most outrageous - and yet paradoxically the most conservative - solution is to alter an assumption so ingrained in cosmology that most cosmologists have forgotten it is there. Called the cosmological principle it states, in essence, that viewed on sufficiently large scales the universe has no preferred directions or preferred places. "We have unquestioningly lived with this assumption for 85 years," says cosmologist Rocky Kolb.
The Problems in Modeling Nature, With Its Unruly Natural Tendencies, NY Times
Nature is too complex, they say, and depends on too many processes that are poorly understood or little monitored - whether the process is the feedback effects of cloud cover on global warming or the movement of grains of sand on a beach.
Their book, "Useless Arithmetic: Why Environmental Scientists Can't Predict the Future," originated in a seminar Dr. Pilkey organized at Duke to look into the performance of mathematical models used in coastal geology. Among other things, participants concluded that beach modelers applied too many fixed values to phenomena that actually change quite a lot.
A Unified Approach To Attractor Reconstruction, Chaos
Excerpt: In the analysis of complex, nonlinear time series, scientists in a variety of disciplines have relied on a time delayed embedding of their data, i.e., attractor reconstruction. The process has focused primarily on intuitive, heuristic, and empirical arguments for selection of the key embedding parameters, delay and embedding dimension. This approach has left several longstanding, but common problems unresolved in which the standard approaches produce inferior results or give no guidance at all. We view the current reconstruction process as unnecessarily broken into separate problems. We propose an alternative approach that views the problem of choosing all embedding parameters as being one (...).

China's True Dash of Flavor, NY Times
Excerpts: Still, MSG was long considered simply to be a flavor enhancer, with little or no taste of its own. In recent years, however, there has been growing acceptance of the existence of a so-called fifth taste - an addition to the traditional quartet of sweet, sour, salty and bitter - known through an emerging consensus by Ikeda's term, umami. Our tongues, biologists have shown, have distinct receptors that pick up on the taste of MSG and a wider family of umami compounds, and some of our brain cells respond specifically to umami.
Complex Challenges: Global Terrorist Networks
Al Qaeda Chiefs Are Seen to Regain Power, NY Times
Excerpts: Senior leaders of Al Qaeda operating from Pakistan have re-established significant control over their once-battered worldwide terror network and over the past year have set up a band of training camps in the tribal regions near the Afghan border, according to American intelligence and counterterrorism officials.
American officials said there was mounting evidence that Osama bin Laden and his deputy, Ayman al-Zawahri, had been steadily building an operations hub in the mountainous Pakistani tribal area of North Waziristan.
North Africa Feared as Staging Ground for Terror, NY Times
Excerpts: Counterterrorism officials on three continents say the trouble in Tunisia is the latest evidence that a brutal Algerian group with a long history of violence is acting on its promise: to organize extremists across North Africa and join the remnants of Al Qaeda into a new international force for jihad. (...)
They say North Africa, with its vast, thinly governed stretches of mountain and desert, could become an Afghanistan-like terrorist hinterland within easy striking distance of Europe.
Guantanamo Detainees Lose Appeal - Habeas Corpus Case May Go to High Court, Washington Post
Excerpts: In its 2 to 1 decision, the U.S. Court of Appeals for the District of Columbia Circuit upheld one of the central components of the Military Commissions Act, the law enacted last year by a then-Republican-controlled Congress that stripped Guantanamo detainees of their right to such habeas corpus petitions. Lawyers have filed the petitions on behalf of virtually all of the nearly 400 detainees still at Guantanamo, challenging President Bush's right to hold them indefinitely without charges. Yesterday's ruling effectively dismisses the cases. (...)
American Liberty at the Precipice, NY Times
Excerpts: In another low moment for American justice, a federal appeals court ruled on Tuesday that detainees held at the prison camp at Guantanamo Bay, Cuba, do not have the right to be heard in court. The ruling relied on a shameful law that President Bush stampeded through Congress last fall that gives dangerously short shrift to the Constitution.
The right of prisoners to challenge their confinement - habeas corpus - is enshrined in the Constitution and is central to American liberty.
Almost All Justice Terror Stats Wrong, UPI
Excerpts: The U.S. Justice Department inspector general says all but two of 26 sets of statistics about terrorism prosecutions are inaccurate. (...)
The statement called the department's collection and reporting of terrorism statistics "decentralized and haphazard." "We found many cases involving offenses such as immigration violations, marriage fraud, or drug trafficking where Department officials provided no evidence to link the subject of the case to terrorist activity," it added.

The Journal of Developmental Processes will publish its first issue in fall 2006. , The JDP recognizes that complex developmental processes characterize the growth of living organisms. In humans, this complexity is highly elaborated, so that developmental change is affected by many interrelated factors of the body, the mind, family, society and the environment. New discoveries continually add to our understanding of these processes and demonstrate the inadequacy of reductionist approaches.

Why create movies of financial models? Because key stakeholders often don't understand them. The mathematical, data-intensive sphere of quantitative financial analysis can be a black box even for many in the industry. It is vital for users of this analysis to appreciate, understand and buy into, often literally, these difficult and important concepts.
Life: An Introduction to Complex Systems Biology, Kunihiko Kaneko, Springer Series: Understanding Complex Systems, 2006
What is life? Has molecular biology given us a satisfactory answer to this question? And if not, why, and how to carry on from there? This book examines life not from the reductionist point of view, but rather asks the question: what are the universal properties of living systems and how can one construct from there a phenomenological theory of life that leads naturally to complex processes such as reproductive cellular systems, evolution and differentiation? The presentation has been deliberately kept fairly non-technical so as to address a broad spectrum of students and researchers from the natural sciences and informatics.
