Illuminating the Dark Universe, Science
Portraits of the earliest universe and the lacy pattern of galaxies in today's sky confirm that the universe is made up largely of mysterious dark energy and dark matter. They also give the universe a firm age and a precise speed of expansion.(...)
Microwave data observed by the WMAP satellite(...) reveal a universe dominated by dark energy.
Lingering doubts about the existence of dark energy and the composition of the universe dissolved when the WMAP satellite took the most detailed picture ever of the cosmic microwave background (CMB). (...)
The universe is only 4% ordinary matter, (...). And the remainder, 73%, is dark energy.
Excerpts: In tandem with the rise of the information society after World War II, two other developments were of great significance, (1) the Cold War energizing the U.S. Department of Defense to act as driver for technology forecasting and (2) the concern with operations and systems analysis. By 1970, the setting began to change. (a) The Cold War was waning and the limits of systems analysis were becoming apparent (...). (b) The awesome growth of computational power (...) became a kind of laboratory tool for the researcher. One example is the development of "complexity science" (...) complex nonlinear, dynamic, adaptive systems (CAS).

Mobiles 'Narrow Information Gap', BBC News
Mobile phones are helping to bridge the communications divide between the world's rich and poor, a report says.
Mobile phones have taken off in Africa
The Washington-based Worldwatch Institute says that in developing countries, the proportion of people with access to a phone has grown over the past 10 years by more than 25%.
One in five of the world's population had used a mobile phone by 2002, it reports - up from one in 237 in 1992.
The relatively low cost of mobile reception masts has driven this trend.
FCC Investigates Smart Radios, GCN
Excerpts: The Defense Department's next-generation Joint Tactical Radio System uses software-defined radio technologies, which let wireless communications devices switch waveforms. The reprogrammable radios, based on an open-communications architecture, will provide U.S. commanders and warfighters with interoperable voice and data communications capabilities.
The Defense Advanced Research Projects Agency has also funded a number of technologies that use dynamic frequencies. DARPA has funded cognitive radio work (...).
Cognitive radio draws on artificial intelligence to automatically negotiate the best transmission path based on factors it evaluates internally, such as what space other radios are using.
The solution to the piracy conundrum begins with more cooperation among the major players. Media companies should give broadband providers a cut of their revenues in exchange for help policing the heavy file-sharing violators. PC makers could encourage video-on-demand services-and the equipment upgrades they will bring-by adopting copyright protection technologies.
Forecasting Business Cycles Using Deviations From Long-Run Economic Relationships, Macroecon. Dynamics
Abstract: We introduce a new index that explores the linkage between business-cycle fluctuations and deviations from long-run economic relationships. This index is virtually a measure of the distance between an attractor (...). The index is applied to U.S. quarterly data to demonstrate its association with an economy's vulnerability state. We find that the average of the index during expansions negatively correlates with the average contraction in output during recessions. A nonlinear error correction model based on a revised version of the index reveals a forecasting gain as compared to the linear error correction model.
Mathematics Could Stabilize Peace Treaties, Natue Science update
A political scientist at the Santa Fe Institute in New Mexico has devised a mathematical method that could help civil-war negotiators to find the most stable peace treaties.
Less than one in five civil wars end through negotiated settlements.
Elisabeth Wood calculates that a settlement will be stronger and more likely to last if it finds the ideal way to apportion the stakes. For example, if two warring factions each want control of some part of a disputed region, negotiators need to divide the territory in a way that comes closest to satisfying them both.
Modeling Robust Settlements To Civil War, SFI Working Paper
Abstract: Why do some civil war settlements prove robust, while others fail? I show how a settlement's robustness, defined in terms of the risk factor of the mutual-compromise equilibrium, depends on the nature of the stakes of the conflict and the distributional terms of the settlement. I identify the distributional terms of the optimal settlement, namely, that most robust to exogenous shocks to the actors' confidence that the other will continue to compromise. I introduce a measure of the degree of the perceived indivisibility of the stakes, an increase in which not only decreases the range of feasible distributional settlements, but decreases their robustness as well. I explore how intra-party heterogeneity and uncertainty regarding ex-post outcomes lessen the range and robustness of settlements. In the conclusion, I compile the predictions of the model and briefly consider the policy implications.
The Cognitive Foundations Of Cultural Stability And Diversity, Trends in Cognitive Sc.
Abstract: The existence and diversity of human cultures are made possible by our species-specific cognitive capacities. But how? Do cultures emerge and diverge as a result of the deployment, over generations and in different populations, of general abilities to learn, imitate and communicate? What role if any do domain-specific evolved cognitive abilities play in the emergence and evolution of cultures? These questions have been approached from different vantage points in different disciplines. Here we present a view that is currently developing out of the converging work of developmental psychologists, evolutionary psychologists and cognitive anthropologists.
A new robot 'brain', based in part on the workings of the human inner ear, has enabled the production of the world's first small robotic helicopter that can see and think for itself, say Australian researchers.
The Mantis makes it possible for fleets of small drone helicopters to do jobs now done by conventional aircraft, say scientists (CSIRO)
The 'brain' and helicopter - called "Mantis" - was announced this week by CSIRO Complex Systems Integration.
(...)the CSIRO helicopter is the first to fly completely independent of expensive global positioning systems (GPS) guidance. Instead it uses its brain to control its balance and orientation.
Scientists have discovered a new process for how memories might be stored, a finding that could help explain one of the least-understood activities of the brain. What's more, the key player in this process is a protein that acts just like a prion - a class of proteins that includes the deadly agents involved in neurodegenerative conditions such as mad cow disease.
(...) yeast cell turns blue.
The study, (...), suggests that this protein does its good work while in a prion state, contradicting a widely held belief that a protein that has prion activity is toxic or at least doesn't function properly.
Mad Cow Case May Bring More Meat Testing, NYTimes
The officials declined to say exactly what they would recommend, but acknowledged that European and Japanese regulators screened millions of animals using tests that take only three hours, fast enough to stop diseased carcasses from being cut up for food.
Dr. Dave Steffen testing a brain for mad cow disease in 2001 at University of Nebraska at Lincoln.
United States inspectors have tested fewer than 30,000 of the roughly 300 million animals slaughtered in the last nine years, and they get results days or weeks later.
But the American system was never intended to keep sick animals from reaching the public's refrigerators, (...).
Measurements: The Brain Wave Made Me Do It, NYTimes
Excerpts: Now, British researchers say they have figured out a way to use similar brain waves to tell something slightly different: whether someone is about to make a mistake.
The study, presented on Thursday at a conference of the Physiological Society at Cambridge University, reported that changes in a specific, easily monitored kind of brain wave were reliable predictors of a drop in performance on a task requiring prolonged attention.
The researchers focused on a brain wave known as P300, which is generated when the brain encounters a stimulus.
Researchers at the University of Basel, Switzerland, played parents and childless adults recordings of babies' cries and laughter. They measured their brain activity using functional magnetic resonance imaging (fMRI).
Parents' brains fired up more in response to sobs than giggles, the researchers found1. The cries activated one brain region in particular, called the amygdala, which is involved in processing emotions.
Waah: crying provokes parents, but not childless adults.
Neuroscience: ORs Rule the Roost in the Olfactory System, Science
Excerpt: The mammalian olfactory system is capable of detecting thousands of different odor molecules. Considerable evidence suggests that each olfactory neuron expresses only one olfactory receptor (OR) from the large OR family encoded by more than 1000 genes scattered throughout the genome. This phenomenon is known as "the one OR-one neuron rule." Such differential expression of OR genes enables the olfactory system to recognize individual odors and to subsequently create a spatial map of odor identity in the olfactory bulb of the brain.
A "Slurp" Says More Than Ten Beeps, Alphagalileo
Excerpts: Natural warning sounds may be the future in airplanes and perhaps in cars as well. A "slurp" when fuel is low works better than a monotonous beeping sound. (...) has studied how warning sounds function, how we associate sounds, and how new sounds can be designed. Alarm sounds have remained largely the same for many years. They involve (...) sound pulses of different frequency. (...) found that it is easier to remember what an alarms sound means if we can associate it with something we recognize, and that it was also much easier for people to distinguish between several types of sounds
Two Hands, One Brain: Cognitive Neuroscience Of Bimanual Skill, Trends in Cognitive Sc.
Abstract: Bimanual coordination, a prototype of a complex motor skill, has recently become the subject of intensive investigation. Whereas past research focused mainly on the identification of the elementary coordination constraints that limit performance, the focus is now shifting towards overcoming these coordination constraints by means of task symbolization or perceptual transformation rules that promote the integration of the task components into a meaningful `gestalt'. The study of these cognitive penetrations into action will narrow the brain-mind gap and will facilitate the development of a cognitive neuroscience perspective on bimanual movement control.
Abstract: A recent study has shown that information about the duration of brief time intervals acquired by one side of the brain is readily available to the other cerebral hemisphere in a patient in which the corpus callosum and the other forebrain commissures have been sectioned. This strongly suggests that the internal clock that measures time duration is subcortical, and that its output can be easily projected to both hemispheres via subcortical commissures.

Coding And Learning Of Behavioral Sequences, Trends in Neurosc.
Abstract: A major challenge to understanding behavior is how the nervous system allows the learning of behavioral sequences that can occur over arbitrary timescales, ranging from milliseconds up to seconds, using a fixed millisecond learning rule. This article describes some potential solutions, and then focuses on a study by Mehta et al. that could contribute towards solving this puzzle. They have discovered that an experience-dependent asymmetric shape of hippocampal receptive fields combined with oscillatory inhibition can serve to map behavioral sequences on a fixed timescale.

Excerpts: BIO stopped ES cells turning into specialized adult cells, (...). BIO works by activating a set of protein signals - called the Wnt pathway - in the ES cells.
The Wnt pathway is known to be involved in development. (...) researchers reported that it also prevents blood-forming stem cells from turning into other cell types.
The discovery could be useful to scientists who are trying to make therapies based on stem cells. By controlling the Wnt pathway, they could tell the cells when to stay young, and when to specialize.
Evolution: Climb Every Mountain?, Science
Excerpts: Environments are highly variable, providing myriad ecological niches that different species can exploit to ensure their survival. A population of organisms may respond to this variation by becoming niche specialists or by evolving into generalists that can exploit a variety of niches rather than just one. (...) an organism's performance (or fitness) in one specific environment is accompanied by the organism's decreased performance (or fitness) in other environments.
(...)ability of the bacterium Pseudomonas fluorescens to diversify into other niches decreases as the organism becomes a specialist (...).
The Costs Of Specialization, The Scientist
Excerpts: As an organism becomes specialized to a specific ecological niche, its fitness to survive in an alternative niche in the same environment decreases. This long-recognized trend is key to the dynamics of adaptive radiations-concentrated bursts of evolution during which new species or variants rapidly form-diverging from a common ancestor in ecology and phenotype. (...) focus on the constraints regulating this process and report that niche adaptation itself may limit a population's ability to subsequently diversify into other niches (...).
Developmental Biology: Tubulogenesis CLICs into Place, Science
(...) flow of fluids through tubular networks is critical to human existence. Tubes of all sizes are also the essential functional units of many organs, including the vascular system, kidney, and lung. However, (...), the molecular mechanisms that control tube formation (tubulogenesis) and size during development are poorly understood. One of the most powerful models for studying tube formation is the excretory (renal) canal system of the worm Caenorhabditis elegans: As the worm develops, a single excretory cell extends a tubular process along the length of the animal (see the figure).
Going tubal. The CLIC protein EXC-4 is required for regulation of tube size. (...)
The Elephant and the Chili Pepper, NYTimes
Excerpts: The elephant pepper is one of 47 ideas for social change in poor countries that the World Bank recently financed through its Development Marketplace. (...)
Farmers in the Zambezi Valley of Zimbabwe have hit on a novel way to keep elephants from trampling their fields. They surround their crops with rows of chili peppers, whose smell is noxious to elephants. The peppers prevent battles that have harmed both man and animal, save crops and give farmers a lucrative new product to export.
Secret Of 'Strained Silicon' Chips Revealed, NewScientist
The speed of current flow depends on the crystal structure of silicon. Inside the silicon lattice, the electrons around each atom form patterns of energy states called orbitals. These states merge to form a continuous band that allows electrons and positively charged "holes" to move through the lattice.
The orientation of the orbitals is important. Each atom has six lobe-shaped orbitals: two in the direction of electron flow and four that are perpendicular to it (see graphic).
Bifurcation Structures Of Period-Adding Phenomena In An Ocean Internal Wave Model, Int. J. Bifur. & Chaos
Abstract: In this paper, we study bifurcation structures of period-adding phenomena in an internal wave model that is a mathematical model for ocean internal waves. It has been suggested that chaotic solutions observed in the internal wave model may be related to the universal property of the energy spectra of ocean internal waves. In numerical bifurcation analyses of the internal wave model, we illustrate bifurcation routes to chaos and parameter regions where chaotic behavior is observed. (...) we discuss a mechanism of the phenomena from the viewpoint of bifurcation analysis
Randomness in Quantum Computation, Science
Excerpts: The use of random unitary operators may also be essential for characterizing efficiently the way in which the quantum computer is affected by interaction with its environment. A complete characterization of the decoherence process induced by the environment generally requires the application of tomographic techniques, which are known to be exponentially inefficient. However, Emerson et al. argue that by using random evolutions it should be possible to find simple benchmarking tools to properly characterize the most important aspects of decoherence.
Pseudo-Random Unitary Operators for Quantum Information Processing, Science
Excerpt: Unfortunately, the implementation of random unitary operators on a quantum processor is exponentially hard. Here we introduce a method for generating pseudo-random unitary operators that can reproduce those statistical properties of random unitary operators most relevant to quantum information tasks. This method requires exponentially fewer resources, and hence enables the practical application of random unitary operators in quantum communication and information processing protocols. Using a nuclear magnetic resonance quantum processor, we were able to realize pseudorandom unitary operators that reproduce the expected random distribution of matrix elements.
Microsoft Aims To Make Spammers Pay, BBC News
Excerpts: Microsoft researchers have come up with a way to slow down spammers and make them 'pay' for e-mails. (...)
The development has been called the Penny Black project, because it works on the idea that revolutionised the British postage system in the 1830s - that senders of mail should have to pay for it, not whoever is on the receiving end.
Stamp of approval
"The basic idea is that we are trying to shift the equation to make it possible and necessary for a sender to 'pay' for e-mail," explained Ted Wobber of the Microsoft Research group (MSR).
Software Shares Out Spare Processing Power, NewScientist
Excerpts: But until now, it has only been possible to subscribe to one of these services at a time. (...) new system that will make it possible to run several distributed computing projects on a single computer, and even let you specify what proportion of the computer's resources is donated to each project.
It is called the Berkeley Open Infrastructure for Network Computing (BOINC). BOINC acts like a software platform that can run a number of screen-saver style applications on top of the PC's own operating system.
Examining Halliburton's 'Sweetheart' Deal in Iraq, NPR Audio
Experts Say Lucrative Contracts Yield Razor-Thin Profit Margins According to KBR's latest quarterly report, the profit margin on military services is 3.8 percent. (Typical defense contracts yield profit margins of 7 percent.) With a profit margin that razor thin, the company has to be efficient, (...). The Iraq contracts are cost-plus: the government reimburses the company for its costs, then adds on a profit of 2 percent to 7 percent. Critics say this creates a perverse incentive: the more you spend, the more you make. The Pentagon says this type of flexible contract is necessary in a war zone.

Complex Challenges: Global Terrorist Networks
Hussein's Capture Not Likely to Harm Al Qaeda, Washington Post
Excerpts: Some terrorism experts, including a few favored by the Bush administration, view Iraq as a key al Qaeda supporter and believe Hussein's capture serves as a deterrent for other terrorist organizations. The more common view, however, is that there was never a strong link or even an ideological bond between Hussein's government and Osama bin Laden's terrorist network, and that the capture could well push al Qaeda to prove it is still relevant.
(...) reinforced recently when intelligence sources were reporting that bin Laden was again in communication with his followers.
Book Report Excerpts: Religious discourse is the best way to gain leverage over the political competition, and "radical Islam is appealing because it offers a framework for a moral/ethical critique of power."
Of course, external factors have an influence. Film footage of fellow Muslims suffering under Western attack in Iraq and Afghanistan inflames passions. The belief that the U.S. turns a blind eye to Palestinian tragedies and Israeli injustices has a profound impact on Muslim attitudes.
(...)best vaccination against the terrorist contagion is a liberal arts education that encourages critical, analytical, multidimensional thinking.
