A Breed Apart - Olympic Athletes Are On The Edge Of Normal Physiology, Nature
Excerpts: Only those whose genes are preset for maximal athletic performance will ever join the élite band of Olympic athletes. Eero Mäntyranta, the 1964 Finnish cross-country skiing gold medallist, for example, had a mutation in the gene encoding for erythropoietin, a protein that regulates the production of red blood cells, which sports scientists believe accounted for his extraordinary stamina. There are hundreds of other genes - from those determining body proportions to those optimizing oxygen and nutrient utilization by muscles - that help tip the balance towards élitism.
Study Suggests Humans Can Speed Evolution, ScienceDaily
Excerpts: It's no secret that life in the 21st century moves at a rapid pace. Human inventions such as the Internet, mobile phones and fiber optic cable have increased the speed of communication, making it possible for someone to be virtually in two places at once. But can humans speed up the rate of one of nature's most basic and slowest processes, evolution? (...) humans may have sped up the evolutionary clock for one species of fish. Cichlid fish are well known to biologists for their rapid rate of evolution. (...) the fish had evolved into two genetically distinct varieties in less than 20 years.
What Dreams Are Made Of, Newsweek
New technology is helping brain scientists unravel the mysteries of the night. Their work could show us all how to make the most of our time in bed.
The long-range goal of dream research is a comprehensive explanation of the connections between sleeping and waking, a multidimensional picture of consciousness and thought 24 hours a day. In the meantime, dream science is helping us understand and treat depression, posttraumatic stress, anxiety and a whole range of other problems. Neuroscientists are gleaning insights into how we learn by studying the physiology of dreaming in adults and children. Psychologists are also studying dreams to learn how both ordinary people and great artists resolve problems in their life and work by "sleeping on it."

Pain In The Brain: It's Not What You Imagine, Alphagalileo
Excerpts: Researchers are one step closer to unravelling the mystery of medically unexplained pain such as chronic low back pain, which continues to baffle doctors. A study exploring the experience of pain in hypnotised volunteers has found that some types of pain which cannot be traced to a medical condition may have its origins in our brains, not in our bodies. The study (...) found that volunteers who felt pain as a result of hypnotic suggestion showed strikingly similar brain activity to those subjected to physical pain via pulses of heat at 49 degrees Celsius.
Depression Traced To Overactive Brain Circuit, ScienceDaily
Excerpts: A brain imaging study (...) has found that an emotion-regulating brain circuit is overactive in people prone to depression - even when they are not depressed. Researchers discovered the abnormality in brains of those whose depressions relapsed when a key brain chemical messenger was experimentally reduced. Even when in remission, most subjects with a history of mood disorder experienced a temporary recurrence of symptoms when their brains were experimentally sapped of tryptophan, the chemical precursor of serotonin, the neurotransmitter that is boosted by antidepressants. Neither a placebo procedure in patients nor tryptophan depletion in healthy volunteers triggered the mood and brain activity changes. (...)
The Pleasure Of Learning, Nature
Excerpts: In my subsequent 40 years of research, there have been times of stress, frustration and disappointment. These are suffered in the hope that a discovery will bring everlasting joy, fame and fortune. But this is not a life. The fun and excitement must be daily - in the challenge of creating an instrument and seeing it work, the joy of communicating to colleagues and students, the pleasure of learning something new, in lectures, corridors and journals. And underlying it all, the sense of wonder that nature is comprehensible.
Science Secret Of Grand Masters Revealed, Nature
Excerpts: She found that novices were more likely to convince themselves that bad moves would work out in their favour, because they focused more on the countermoves that would benefit their strategy while ignoring those that led to the downfall of their cherished hypotheses.
Conversely, masters tended to correctly predict when the eventual outcome of a move would weaken their position. "Grand masters think about what their opponents will do much more," says Byrne. "They tend to falsify their own hypotheses."
Semantic Linking - a Context-Based Approach to Interactivity in Hypermedia, arXiv
Abstract: The semantic Web initiates new, high level access schemes to online content and applications. One area of superior need for a redefined content exploration is given by on-line educational applications and their concepts of interactivity in the framework of open hypermedia systems. In the present paper we discuss aspects and opportunities of gaining interactivity schemes from semantic notions of components. A transition from standard educational annotation to semantic statements of hyperlinks is discussed. Further on we introduce the concept of semantic link contexts as an approach to manage a coherent rhetoric of linking. A practical implementation is introduced, as well. Our semantic hyperlink implementation is based on the more general Multimedia Information Repository MIR, an open hypermedia system supporting the standards XML, Corba and JNDI.
Ice Age Cereal - Seeds On A 22,000-Year-Old Grindstone, Science Now
Excerpts: By measuring how much starch the seeds contained-(...)--they found that only two of the 34 species of grass were on the grinding stone: wild barley and wheat. That makes sense, Piperno says, because unlike other wild grasses, both wheat and barley have to be pounded or ground to remove the fibrous outer hull to achieve maximum nutritional benefit.(...)
Extensive carbon-14 dating of the site places occupation at 23,500 to 22,500 years ago, more than 10,000 years before wheat and barley were domesticated in the region.
Saving The Whales: Lessons From The Extinction Of The Eastern Arctic Bowhead, J. Econ. History
Abstract: In this article we investigate the possibility that a regulatory regime designed to maximize the profitability of the early Dutch whaling industry could have simultaneously guaranteed the biological sustainability of the eastern Arctic Bowhead whale. We find that policies with economic profit as the sole objective could have saved the whales, as well as increasing the incomes of the whalers, under assumptions commonly made in fisheries models. However, the necessary assumptions are implausible. Under more historically relevant assumptions we find that regulation could not have simultaneously increased profits and preserved the stock of whales.
Expecting the Unexpected, Futures
Excerpts: The only certain aspect of the future is that it will be different. Little of our prospect can be seen with confidence, but one idea which shall surely not survive is that of the readily foreseeable future. Many thinkers are now less interested in predicting and thus determining the future, precisely because they do not believe that linear, programmatic determinism is the right angle of attack. They see themselves more as conceptual gardeners, planting for fruitful growth, rather than engineers designing eternal, gray social machines. (...) The most difficult of all predictions is how all these social and scientific forces will intermingle, yielding a world as different from ours as we are from the optimistic security of 1900.

That's My Hand! Activity in Premotor Cortex Reflects Feeling of Ownership of a Limb, Science
Abstract: When we look at our hands, we immediately know that they are part of our own body. This feeling of ownership of our limbs is a fundamental aspect of self-consciousness. (...). A perceptual illusion was used to manipulate feelings of ownership of a rubber hand presented in front of healthy subjects while brain activity was measured by functional magnetic resonance imaging. The neural activity in the premotor cortex reflected the feeling of ownership of the hand. This suggests that multisensory integration in the premotor cortex provides a mechanism for bodily self-attribution.
Probing the Neural Basis of Body Ownership, Science
Excerpts: In the cognitive sciences, the most challenging phenomena are often the ones we take for granted in our everyday lives. An excellent example is body ownership. (...) But how do we distinguish our bodies, but not other objects, as belonging to ourselves, and what is the basis for the associated feeling of identification or ownership? (...) only recently has it attracted the interest of neuroscientists.
(...) body is distinguished from other objects by its involvement in the correlation or matching of special patterns of intersensory information.
Social Status Influences Brain Structure, Nature
Excerpts: Within three days, the males had established their preferred pecking order: an aggressive leader who attracted the females and three defensive subordinates.
Two weeks later, the high-status animals were found to have around 30% more neurons in their hippocampus, a brain region implicated in learning and memory, than they had before.
Neurons in this area are constantly recycled, says Kozorovitskiy. Around 9,000 new nerve cells are born every day, but most die within a week. In the dominant animals, however, the new cells survive for longer.
Parasitic Birds 'Happy To Share', BBC News Online
A type of parasitic bird, which is reared by unrelated host "parents", is happy to share its nest with the host's babies, (...).
Traditional theory predicts that parasitic birds should push host chicks from the nest
Traditional theory predicts that parasitic birds should push host chicks from the nest, to avoid sharing food.(...)
This occupation requires a rather nomadic life-style: the cowbirds are obliged to go where the herds go. This makes bringing up young problematic.
Nest-building and chick-rearing fixes you to the spot for a while, which the cowbirds can little afford.
Birds Flew Earlier Than Previously Thought, Scientists Say, NY Times
Excerpts: Scientists have determined that the ancient avian fossil Archaeopteryx was definitely bird-brained, meaning no disrespect. (...)
The new research suggested, moreover, that birds probably started flying millions of years earlier than scientists previously thought. It is just that fossils of the first flying birds have eluded paleontologists.
(...) first X-ray examination and reconstruction of the braincase and inner ear of a 147-million-year-old Archaeopteryx specimen. They found that the size, shape and volume of its brain were similar to that the modern eagle or sparrow.
Flying Dinosaur Had 'Bird Brain', Nature
It was half-bird, half-reptile and it soared above the still lagoons of Bavaria 147 million years ago. Researchers have confirmed that Archaeopteryx had a brain and body geared for flight, earning it the moniker of the world's most primitive bird.
Archaeopteryx: now officially the world's most primitive bird.
Ever since the first fossilized remains were found in 1861, Archaeopteryx has courted controversy. The enigma combines the feathered wings and wishbone of birds with the teeth and long, bony tail characteristic of reptiles, causing many to view it as an intermediate between the two groups.
Salmon Give Birth To Trout, Nature
Excerpts: Japanese researchers have pioneered a breeding technique that allows salmon to father baby trout. (...).
The researchers managed to create male salmon that produce sperm of a closely related trout species. When used to fertilize trout eggs, the sperm produced perfectly healthy young trout, (...).
The technique involves cells called primordial germ cells (PGCs), which are found in embryos and can develop into either eggs or sperm. Yoshizaki's team injected PGCs from rainbow trout (Oncorhynchus mykiss) into young male masu salmon (Oncorhynchus masou), and let the salmon mature.
Cell Swap Could Help Conservation, BBC News
Japanese scientists have developed a new kind of assisted reproduction for animals, in which one species can create another.
Trout, like this five-month old juvenile, were created using surrogate sperm from salmon
They implanted tissue from trout embryos into salmon embryos; and when the salmon became adults and mated, they produced trout.
The researchers suggest this could be a way to improve the chances of endangered species,
When the salmon had grown to maturity and mated with each other, most of the offspring were trout-salmon hybrids which died quickly.
However, some were pure trout - an identity confirmed by genetic analysis.
The Ubiquity Of Small Species: Patterns Of Local And Global Diversity, BioScience
Abstract: Small organisms (less than 1 millimeter in length) tend to have a cosmopolitan distribution. This is a consequence of huge absolute population sizes rather than any inherent properties of particular taxonomic groups. At the local scale, the diversity of small species exceeds that of larger organisms, but at the global scale this relation is reversed, because endemism is largely responsible for the species richness of large organisms. For small organisms, the relationship between species and area is flat, and a latitudinal diversity gradient is absent or weak. These patterns are explained by some of the assumptions underlying the unified neutral community model.
A Proposal for Using the Ensemble Approach to Understand Genetic Regulatory Networks, Journal of Theoretical Biology
Excerpt: Understanding the genetic regulatory network comprising genes, RNA, proteins and the network connections and dynamical control rules among them, is a major task of contemporary systems biology. I focus here on the use of the ensemble approach to find one or more well-defined ensembles of model networks whose statistical features match those of real cells and organisms. Such ensembles should help explain and predict features of real cells and organisms. More precisely, an ensemble of model networks is defined by constraints on the "wiring diagram" of regulatory interactions, and the "rules" governing the dynamical behavior of regulated components of the network. The ensemble consists of all networks consistent with those constraints. (...)
Modeling A Synthetic Multicellular Clock: Repressilators Coupled By Quorum Sensing, PNAS
Author's Summary: This paper asks how one might couple a population of synthetic gene
oscillators, known as "repressilators," in such a way that they will
self-synchronize, despite the heterogeneity in the cells themselves. The
scheme proposed here seems to be biochemically feasible, and works well in
numerical simulations. It relies on the sort of technical wizardry made
possible today by genetic engineering; the cells are coaxed to interact by
the "quorum-sensing" mechanism that operates between certain bacterial
cells, mediated by the diffusion of a signaling molecule. The goal is to
synthesize the analog of a multicellular biological clock.

Defibrillators Get Less Shocking, Nature
Excerpts: Heart attacks increase the risk of fibrillation because they leave scars of dead tissue inside the heart, (...). This allows rotating electrical waves to develop around these areas, which disrupt the heart's normal electrical activity. (...).
Efimov has modelled these waves to come up with a gentler way to restart the heart. By timing the shock so that it arrives just as the wave is passing around the scar tissue, he says it is possible to dislodge and quench the electrical tornado using only half a joule of energy (...).
POEtic: An Electronic Tissue for Bio-inspired Cellular Applications, Biosystems
Abstract: In this paper, we introduce the general architecture of a new electronic tissue called POEtic. This reconfigurable circuit is designed to ease the implementation of bio-inspired systems that bring cellular applications into play. It contains special features that allow a developer to realize systems that require evolution (Phylogenesis), development (Ontogenesis), and/or learning (Epigenesis). A dynamic routing algorithm has been added to a structure similar to that of common commercial FPGAs ["Field Programmable Gate-Array", Ed.], in order to allow the creation of data paths between cells. As the creation of these paths is dynamic, it is possible to add new cells or to repair faulty ones at runtime.
Separating Internal and External Dynamics of Complex Systems, Phys. Rev. Lett.
Excerpts: The observable behavior of a complex system reflects the mechanisms governing the internal interactions between the system's components and the effect of external perturbations. Here we show that by capturing the simultaneous activity of several of the system's components we can separate the internal dynamics from the external fluctuations. The method allows us to systematically determine the origin of fluctuations in various real systems, finding that while the Internet and the computer chip have robust internal dynamics, highway and Web traffic are driven by external demand. As multichannel measurements are becoming the norm in most fields, the method could help uncover the collective dynamics of a wide array of complex systems.
Invisible Cities: A Metaphorical Complex Adaptive System, Festina Lente Press

from computer scientist and complexity expert, John Holland's "seven basics"
shared by all cas. In place of Marco Polo's accounts of cities found in
Calvino's work, "Invisible Cities: A Metaphorical Complex Adaptive System"
gives examples of the principles of cas drawn from the physical and biological
sciences, the arts, philosophy, and games.
Blown By Wind: Nonlinear Dynamics Of Aeolian Sand Ripples, Physica D
Excerpts: A nonlinear continuum model is considered that describes the dynamics of two-dimensional aeolian sand ripples. (...) shows that a flat sand bed exposed to the action of wind is linearly unstable to long-wavelength perturbations. As the ripples grow, nonlinear effects become important, ripples become asymmetric and the wavelength increases due to merging events. A long-wavelength approximation to the full integral model is then derived. The ripple field produced by the long-wave theory undergoes coarsening, drifts downwind and displays bifurcations and defects which move from one ripple to another, similar to what is observed for sand ripples in the desert.

The Assessment Of Social Functioning In Individuals With Mental Retardation: A Review, Behav. Modification
Abstract: Social skills deficits and excesses are a defining aspect of mental retardation (MR). Research indicates that there is an established relationship between social skills and maladaptive behaviors. A number of studies demonstrate that the social competence of individuals with MR and comorbid psychopathology can be enhanced with social skills training. However, to design an effective training package, an accurate assessment of adaptive and social functioning must first be conducted. Unique problems arise when assessing social skills in individuals with severe and profound MR (i.e., individuals often have limited verbal repertoires). (...)
Rolling Down the Highway, Looking Out for Flawed Elections, NY Times
Excerpts: Ms. Harris worries a lot about this year's election. One of the key vulnerabilities, she says, is the central tabulator, which could control a million or more votes in some counties. There will be thousands of election workers - including temporaries who may not even have had their backgrounds checked - with access to these computers, who she believes could change vote totals rapidly. "It isn't hacking an election," she says. "It's editing an election." She and many computer scientists worry that modems on the machines will make them vulnerable.
Editor’s Note: Now that it seems to be clear that the voting machines cannot be made secure before November one could expect that the outcome of the election will be strongly influenced by who is most ruthless and effective in manipulating the voting machines. (Unless voters can be convinced that voting machines are not trustworthy and that they have the alternative of voting by absentee ballots.)
Besides hacking into the computers the votes could also be influenced by deliberate acts of sabotage like crashing the machines to make them unavailable (this could even be done remotely e.g. by using EMP devices from an SUV in the parking lot) or even by cutting power to the poll stations.
Since the anticipated outcomes is known in many districts one could expect that , e.g. militant activists who want to prevent a re-election of the current president would target voting machines in predominantly Republican districts.
Electronic Voting Still Controversial, NPR TOTN
Excerpts: Across the country, officials must decide if computerized voting machines are secure and open to audit. We consider the latest in electronic voting technology.
Diplomacy Fails to Slow Advance of Nuclear Arms, NY Times
Excerpts: American intelligence officials and outside nuclear experts have concluded that the Bush administration's diplomatic efforts with European and Asian allies have barely slowed the nuclear weapons programs in Iran and North Korea over the past year, and that both have made significant progress.
(...) senior administration and intelligence officials say they are seeking ways to step up unspecified covert actions intended, in the words of one official, "to disrupt or delay as long as we can" Iran's efforts to develop a nuclear weapon.
Korean Missile Said to Advance; U.S. Is Unworried, NY Times
Excerpts: North Korea appears closer to deploying a new mobile ballistic missile that is a worrisome increase in that nation's military capacity, but American government officials stressed Wednesday that the weapon could not reach the continental United States.
North Korea does not have a submarine capable of carrying the missile to within striking range of the continental United States. Officials also expressed doubts that the North Korean government had developed the missile for the purpose of hiding it inside freighters to be sailed closer to this nation's shores for launch.
Washington's Gift to Bomb Makers, NYTimes
Excerpts: There is no bigger and more urgent threat to the security of every American than the possibility of nuclear bomb materials falling into the wrong hands. That is why it is astonishing, and frightening, that the Bush administration is now pushing to strip the teeth from a proposed new treaty aimed (...) With talks on the new treaty set to begin later this year, the administration suddenly announced last week that it would insist that no provisions for inspections or verification be included.
US Anti-Drug Campaign 'Failing', BBC News
Excerpts: US drugs tsar John Walters has admitted that Washington's anti-narcotics policy in Latin America has so far failed.
Mr Walters said in Mexico that billions of dollars of investment over many years have failed to dent the flow of Latin American cocaine onto US streets.(...)
Mr Walters was speaking just after he had visited Colombia, where US-backed efforts to wipe out drug-smuggling gangs and eradicate coca crops have turned the country into the world's third-largest recipient of US military aid.
New Rules on When to Go to War, Financial Times
Excerpts: Underlying the debate about the wisdom of the US-led intervention in Iraq lies the deeper issue of when, in an age of unconventional threats, to use military force and whether that force must meet some broadly accepted standard of "legitimacy". Americans in this presidential election year remain deeply divided over this issue-as do their transatlantic allies and much of the rest of the world. These divisions will not disappear under a new US president, for they reflect the realities of today's world far more than the desires of a particular American administration.

Qaeda Strategy Is Called Cause for New Alarm, NY Times
Excerpts: (...) even after extensively considering and then dismissing a possible target, the terrorists have simply switched their focus to another location, (...)
Such attention to detail, the willingness to wait for the opportune moment to attack, and the capacity to revise strategies if necessary, has been illustrated in other Qaeda operations. The preparations for the Sept. 11 attacks have been well documented, such as the hijackers' use of small rented aircraft to conduct pre-strike reconnaissance flights near the Pentagon and their cross-country surveillance flights (...).
Excerpts: (...) Pakistan will in turn come under its glare as the United States and England rachet up efforts to crush Al Qaeda (...).
Pakistan is "widely seen as the ground zero of terrorism," and a "flurry of arrests over the last 48 hours of suspected Al Qaeda elements, all of whose trail leads back to Pakistan," further confirms this, reports the Times.
CNN reports that the recent arrests "have exposed an intricate web of Al Qaeda contacts in which the terror network's operational information flowed among Pakistan, Britain and the United States."
How The Pakistani Double Agent Was ‘Burned' By The US, Pakistan Daily Times
Excerpts: On 2 August, the Bush administration blew the cover of double agent Muhammad Naeem Noor Khan. A day earlier, Homeland Security Secretary Tom Ridge had announced a new alert against an Al Qaeda plan to attack financial institutions in New York and Washington. When the New York Times pressed certain administration officials for more information, they disclosed to the newspaper that the information regarding the Al Qaeda plot had come from a recently arrested man in Pakistan named "Khan." The New York Times published his name on Monday.
Defense Dept. Hopes To Enlist AI In War Against Terrorism, Mercury News
Excerpts: (...) used pattern recognition techniques to show that it was possible to spot odd relationships in data. (...)
The system then recommended that the agent look into a series of events: a missing persons report filed on an industrial worker, a blueprint of the switches to a dam found on an Al-Qaida computer, and hacking tools found on other Al-Qaida computers.
``You could put that together to say that the terrorists were possibly planning to attack the dam,'' (...) government agents could spend more time investigating actual incidents, (...).
f. Impervious Shield Elusive Against Drive-By Terrorists, Washington Post
Excerpts: The United States has spent more than $1 billion (...) to stop a single threat: the explosion of a car or truck bomb at a government installation or other structure. (...) nearly three years after the Sept. 11, 2001, terrorist attacks, even senior federal agents acknowledge that the country has virtually no defense against a terrorist barreling down the street with a truck bomb.
"If a person doesn't care about dying, they can pull right up to a building, push a button and the building would go,"(...).
