For Wall Street's Math Brains, Miscalculations, Washington Post 
Excerpts: Complex Formulas Used by 'Quant' Funds Didn't Add Up in Market Downturn Short for "quantitative equity," a quant fund is a hedge fund that relies on complex and sophisticated mathematical algorithms to search for anomalies and non-obvious patterns in the markets. These glitches, often too small for the human eye, can present opportunities for short- and long-term trades that yield high-profit returns.
The models replace instinct. They try to turn historical trends into predictive science, using elegant mathematics seemingly above the comprehension of your average 401(k) participant or Wall Street fund manager. (...)
Reductionism, Emergence, and Levels of Abstractions, arXiv
Abstract: Can there be independent higher level laws of nature if everything is reducible to the fundamental laws of physics? The computer science notion of level of abstraction explains why there can -- illustrating how computational thinking can solve one of philosophy's most vexing problems.
A Practical Ontology for the Large-Scale Modeling of Scholarly Artifacts and their Usage, arXiv
Abstract: The large-scale analysis of scholarly artifact usage is constrained primarily by current practices in usage data archiving, privacy issues concerned with the dissemination of usage data, and the lack of a practical ontology for modeling the usage domain. As a remedy to the third constraint, this article presents a scholarly ontology that was engineered to represent those classes for which large-scale bibliographic and usage data exists, supports usage research, and whose instantiation is scalable to the order of 50 million articles along with their associated artifacts (e.g. authors and journals) and an accompanying 1 billion usage events. The real world instantiation of the presented abstract ontology is a semantic network model of the scholarly community which lends the scholarly process to statistical analysis and computational support. We present the ontology, discuss its instantiation, and provide some example inference rules for calculating various scholarly artifact metrics.
EA Games to Incorporate Real-Time Weather, Wired
Excerpts:  At the click of a button, the video game screen shows current weather conditions for the real-world stadium, giving gameplay some extra realism. Photo credit: Courtesy of Electronic Arts. |
With ground visuals in games nearly perfected, the latest step toward realism in sports video games is focused on the skies. EA Sports' NCAA 08 Football, released July 17, is the first game to pipe in real-time weather conditions at the venue of a player's choice, thanks to a collaboration with the Weather Channel. From a snowstorm in Boston to a heat wave in Arizona, the exact environment will not only affect the visuals but also alter game dynamics.
"Rain will cause more fumbles, you'll see players breathe in the cold, and they'll get tired when it's hot," said Tyrone Miller, a spokesman for EA Sports.
Federal No-Bid Contracts On Rise - Use of Favored Firms A Common Shortcut, Washington Post
Excerpts: A recent congressional report estimated that federal spending on contracts awarded without "full and open" competition has tripled, to $207 billion, since 2000, with a $60 billion increase last year alone. The category includes deals in which officials take advantage of provisions allowing them to sidestep competition for speed and convenience and cases in which the government sharply limits the number of bidders or expands work under open-ended contracts. Government auditors say the result is often higher prices for taxpayers and an undue reliance on a limited number of contractors.
Warming Will Exacerbate Global Water Conflicts, Washington Post
Excerpts: As global warming heats the planet, there will be more desperate measures. The climate will be wetter in some places, drier in others. Changing weather patterns will leave millions of people without dependable supplies of water for drinking, irrigation and power, a growing stack of studies conclude. At Stanford University, 170 miles away, Stephen Schneider, editor of the journal Climatic Change and a lead author for the authoritative Intergovernmental Panel on Climate Change (IPCC), pours himself a cup of tea and says the future is clear.
Climate Tipping Points Loom Large, New Scientist
Excerpts: Some climate tipping points may already have been passed, and others may be closer than we thought, it emerged this week. Runaway loss of Arctic sea ice may now be inevitable. Even more worrying, and very likely, is the collapse of the giant Greenland ice sheet. So said Tim Lenton of the University of East Anglia, UK, speaking on Monday at a meeting on complexity in nature, organised by the British Antarctic Survey in Cambridge.
Oceans: A Change In Circulation?, Science
Excerpts: This decrease in the meridional overturning circulation is much larger than suggested by climate model simulations of the 20th century, and more akin to the up to 50% decrease projected for the end of the 21st century. Are the models not responding rapidly enough to greenhouse gas changes, or was the observed change--as Bryden et al. cautioned--uncomfortably close to the uncertainties in previous observational estimates? It remains unclear how much the meridional overturning circulation varies from year to year. Understanding this variability will be critical to improving models, thus allowing more reliable projections of climate change.
Environment: Carbon Mitigation By Biofuels Or By Saving And Restoring Forests?, Science
Excerpts: Choosing from among the host of strategies for mitigation of anthropogenic carbon emissions is not easy. There are competing environmental priorities, social and economic factors, and commercial and political interests. One strategy that has received extensive attention is the use of biofuels for transport, particularly ethanol from fermentation of carbohydrate crops as a substitute for petrol and vegetable oils in place of diesel fuel. (...) In all cases, forestation of an equivalent area of land would sequester two to nine times more carbon over a 30-year period than the emissions avoided by the use of the biofuel.
Beijing: Traffic Ban Cleared The Air, AP/Guardian
Excerpts: Despite a persistent gray haze, officials said Tuesday an exercise that removed more than 1 million private vehicles a day from Beijing's gridlocked streets was a success that could mean a clearer sky during next summer's Olympics. Humidity and wind conditions kept the pollution from dispersing, but the air during the four-day drill would have been much worse without the vehicle restrictions, said Du Shaozhong, the deputy director of the Chinese capital's Environmental Protection Bureau.
Biodiversity: Predicting Oblivion: Are Existing Models Up To The Task?, Science
Excerpts: Huge numbers of species may be at risk of extinction from climate change, but coming up with precise estimates is proving tough Much of the current debate over climate-triggered extinctions focuses on what are known as climate-envelope models. Scientists analyze all the places where a species has been recorded and look for features of the climate that those places share. The key factors may be rainfall, for example, or the temperature during the winter.
Female Mate-Choice Drives The Evolution Of Male-Biased Dispersal In A Social Mammal, Nature
Excerpts: Here we show that male-biased dispersal in the spotted hyaena (Crocuta crocuta) most probably results from an adaptive response by males to simple female mate-choice rules that have evolved to avoid inbreeding. Microsatellite profiling revealed that females preferred sires that were born into or immigrated into the female's group after the female was born. Furthermore, young females preferred short-tenured sires and older females preferred longer-tenured sires.

Uncertainties Of Savanna Habitat Drive Birds To Cooperative Breeding, ScienceDaily
Excerpts: Delaying having kids to help raise the offspring of others seems like a bad choice if you want to reproduce, but many African starlings have adopted this strategy to deal with the unpredictable climate of their savanna habitats, according to a new study (...). This behavior, called cooperative breeding, is typical of many animals, from insects and shrimp to birds and even humans, but the reasons underlying its evolution and distribution among such a wide array of species have been unclear. (...)
Puppy Love Makes Teenagers Lose The Plot, New Scientist
Excerpts: The behaviour of a teenager who has fallen madly in love is akin to that of a patient with a psychiatric disorder (...) The lovestruck teenagers showed many behaviours resembling "hypomania" - a less intense form of mania. For example, they required about an hour less sleep each night than teens who didn't have a sweetheart. They were also more likely to report acting compulsively, with 60% saying they spent too much money compared with fewer than 30% of teenagers who were not in love.
Neuroscience: Enzyme Keeps Old Memories Alive, Science
Excerpts: Many substances interfere with memory, as any hung-over partygoer can attest. But although booze and drugs can disrupt the making of new memories (such as the embarrassing antics at last night's party), they leave older memories intact. Neuroscientists think this is because, after a time, memories become wired into the brain in a way that makes them harder to wipe out: Long-term memories, in the generally accepted view, are maintained by structural changes to the synaptic connections between neurons.
Rapid Erasure of Long-Term Memory Associations in the Cortex by an Inhibitor of PKM, Science
Excerpts: Little is known about the neuronal mechanisms that subserve long-term memory persistence in the brain. The components of the remodeled synaptic machinery, and how they sustain the new synaptic or cellwide configuration over time, are yet to be elucidated. In the rat cortex, long-term associative memories vanished rapidly after local application of an inhibitor of the protein kinase C isoform, protein kinase M zeta (PKM ). The effect was observed for at least several weeks after encoding and may be irreversible.
Neuroscience: Synapses Here And Not Everywhere, Science
Excerpts: Brain function depends on a vast array of synapses, or connections, between neurons. The overall architecture of these networks is defined by the creation of specific synapses as well as by the removal or pruning of excess connections. Pruning is particularly dramatic in the human brain, in which an estimated 40% of synapses generated during postnatal growth are eliminated by adulthood (1). The scope of this phenomenon argues for robust mechanisms that select synapses for preservation or destruction, but the molecular details are obscure.
Correlation Between Neural Spike Trains Increases With Firing Rate, Nature
Excerpts: It is not clear, for instance, whether correlations between the discharges of two neurons are determined solely by the correlation between their afferent currents, or whether they also depend on the mean and variance of the input. We addressed this question by computing the spike train correlation coefficient of unconnected pairs of in vitro cortical neurons receiving correlated inputs. Notably, even when the input correlation remained fixed, the spike train output correlation increased with the firing rate, but was largely independent of spike train variability.
Brain Implant Being Studied at Jefferson Could Predict and Stop Epilepsy Seizures Before They Even Begin, Jefferson Hospital News Release
Excerpts: The RNS [Responsive Neurostimulator System, Ed.] system is an implantable device designed to detect abnormal electrical activity in the brain and deliver small amounts of electrical stimulation in response. It is placed by a surgeon within the skull and beneath the scalp. The device is then connected to two wires containing electrodes that are placed within the brain or resting on the brain surface in the area of the seizure focus. By continuously monitoring brain electrical activity, after identifying the "signature" of a seizure's onset, the device delivers brief electrical stimulations with the intention of suppressing the seizure before any symptoms occur.
Achievement Index Climbs The Ranks, Nature
Excerpts: From a selection of well-cited papers in the journal Physical Review B, Hirsch selected 50 authors who had started publishing papers in the 1980s, and assessed how their careers had developed. He calculated how well various metrics - the h-index, the number of publications (productivity), the number of citations and the mean number of citations - during the first 12 years of their publishing career predicted the values over the next 12. But rather than assessing the cumulative impact of previous and future work, he investigated how well the indices predicted the quality of subsequent work.
Artificial Intelligence Applications In The Telecommunications Industry, Expert Sys.
Abstract: Artificial intelligence (AI) has been applied to the telecommunications industry for more than a decade. The purpose of this paper is to examine the application of AI in the telecommunications industry sector. Our research finds that AI's first main application in telecommunications is in the network management area. Expert systems and machine learning are the two AI techniques that have been widely used in telecommunications, while machine learning and distributed artificial intelligence are the two AI techniques which are most promising for the future. The research also finds that different AI techniques have their unique applications in the telecommunications industry.
Swarming Starlings Help Probe Plasma, Crowds And Stock Market, ScienceDaily
Excerpts: (...) found a powerful technique that could be used to detect precisely when ordered patterns form in everything from plasma in the solar wind and fusion reactors, to crowds of people, or flocks of birds. The technique could even be used to find unusual patterns in stock market behaviour. The researchers began their work in a research group interested in plasmas. (...) plasmas in nuclear fusion reactions are obviously not easily accessible. (...) researchers were particularly interested in how complex systems such as plasma, crowds of people, or flocks of birds suddenly move from a disordered random state to an ordered one. (...)
Monkeys Learn To Do Arithmetic For Peanuts, New Scientist
Excerpts: Capuchin monkeys can be taught to appreciate the relative value of coloured tokens representing coins for buying food It takes a smart monkey to do mathematics, and although Elsa Addessi insists her 10 capuchins aren't quite doing sums, she admits they must be pretty clever to be able to pass the tests that she has put them through. One can even handle multiplication.
Addessi, a researcher at the Institute of Cognitive Sciences and Technologies in Rome, Italy, tested whether her capuchins could understand the value of monkey money, and then use it to buy the greatest amount of food.
Physicists Discover Inorganic Dust With Lifelike Qualities, Science Daily
Excerpts:  Could extraterrestrial life be found in particles of interstellar dust (like that which obscures the giant molecular cloud DR21, shown here in an infrared image taken recently by the orbiting Spitzer Space Telescope)? (Credit: A. Marston (ESTEC/ESA) et al., JPL, Caltech, NASA) |
The findings hint at the possibility that life beyond earth may not necessarily use carbon-based molecules as its building blocks. They also point to a possible new explanation for the origin of life on earth. Life on earth is organic. It is composed of organic molecules, which are simply the compounds of carbon, excluding carbonates and carbon dioxide. The idea that particles of inorganic dust may take on a life of their own is nothing short of alien, going beyond the silicon-based life forms favoured by some science fiction stories.
Helices Swirl In Space-Dust Simulations - Plasmas Put A New Twist On Life, PhysicsWorld
Excerpts:  Sketch of how two different helical structures (two columnar structures on the left) could interact via a vortex of dust (oblong structure between the two columns). In this example the two resultant helical structures (on the right) are identical. |
Swirling clouds of dust in space could harbour something akin to life -- according to computer simulations done by physicists in Russia, Germany and Australia. The simulations suggest that under certain conditions, dust particles could join together to form double-helix structures similar to DNA and even divide to create two identical copies of the same structure. Although the simulated dust is inorganic and so does not contain the carbon-based molecules found in all life on Earth, the researchers believe that their results hint at the possibility that inorganic life could exist elsewhere in the universe
Molecular Evolution: Resurrected Proteins Reveal Their Surprising History, Science
Excerpts: (...) researchers report that they resurrected a protein from ancient fish that swam the oceans some 450 million years ago and then worked out the protein's atomic structure. By comparing the protein to more modern versions and doing some deft detective work, they crafted something like a movie of the sequence of key mutations that enabled the ancestral protein to take on new modern functions.(...) Haussler says the work underscores how chance mutations that seemingly add little value initially can help set the stage for major evolutionary leaps. "For me, what is so exciting is seeing the dynamics of evolution play out on the molecular level," Haussler says.
Biological Chemistry: Enzymes Line Up For Assembly, Nature
Excerpts: Many enzymes have a series of catalytic sites, lined up like beads on a string. A previously unknown link in one of these molecular assembly lines involves an unexpected approach to a common biochemical reaction. (...) These multi-subunit enzymes are the molecular equivalents of moving assembly lines: growing substrate molecules are handed, bucket-brigade style, from one specialized catalytic site to the next, with each site performing a specific and predictable function.
Biochemistry: Designer Enzymes, Nature
Excerpts: Chemical reactions in living organisms are catalysed by enzymes, the vast majority of which are proteins. These finely tuned catalysts are the result of billions of years of evolution, and far surpass anything yet created by humans. Indeed, our ability to design enzymes, on the basis of our knowledge of protein structure and reaction mechanisms, can most charitably be described as primitive. The structure and catalytic properties of an enzyme are dictated by its amino-acid sequence in ways that are not understood well enough to reproduce.
Computational Biochemistry: Models Of Transition, Nature
Excerpts: Is it possible to determine the role of an enzyme from its structure? The latest findings suggest that it is, and prove the point by predicting the substrate for an enzyme of unknown function.
Evolution: Jumping Genes Hop Into The Evolutionary Limelight, Science
Excerpts: Call it a molecular gold rush. Researchers sifting through the supposed junk DNA between genes--a whopping 98% of the human genome--have in the past few years hit a mother lode of functional sequence full of clues about how genomes operate and change through time. And, as junk DNA has gained respect, so have mobile bits of DNA called transposons that are often the source of this genomic clutter. Most researchers have taken a dim view of transposons, considering them molecular parasites that clog chromosomes with seemingly useless sequence, sometimes disrupting genes.
Unravelling New Complexity In The Genome, Innovations-report
Excerpts: A major surprise emerging from genome sequencing projects is that humans have a comparable number of protein-coding genes as significantly less complex organisms such as the minute nematode worm Caenorhabditis elegans. Clearly something other than gene count is behind the genetic differences between simpler and more complex life forms. Increased functional and cellular complexity can be explained, in large part, by how genes and the products of genes are regulated. (...) reveals that a step in gene expression (referred to as alternative splicing) is more highly regulated in a cell and tissue-specific manner than previously appreciated (...).
The Common Biology Of Cancer And Ageing, Nature
Excerpts: At first glance, cancer and ageing would seem to be unlikely bedfellows. Yet the origins for this improbable union can actually be traced back to a sequence of tragic - and some say unethical - events that unfolded more than half a century ago. Here we review the series of key observations that has led to a complex but growing convergence between our understanding of the biology of ageing and the mechanisms that underlie cancer.
Are Big Beasts' Cancers Self-defeating?, News@Nature
Excerpt:  It's a mystery why large animals such as whales aren't ridden with tumours. |
Cancer may be more common but less lethal in large animals, say researchers modelling cancer formation. They suggest that tumours in large animals may spawn even more aggressive tumours that stunt their parents' growth.
Disease Dynamics Over Very Different Time-Scales, Interface
Excerpt: We analyse the relationship between the network of livestock movements in the UK and the dynamics of two diseases: foot-and-mouth disease (FMD), which has an incubation period of days, and scrapie, which incubates over years. For FMD, the time-scale of expected epidemics is similar to the time-scale of the evolution of the network. We argue that, under appropriate conditions, a static network analysis can be an appropriate tool for gaining insights into disease dynamics even when the relevant time-scales are similar, as with FMD. We show that a subclass of 'linkage moves' maintains the network structure, (...).
Cell Biology: Aneuploidy In The Balance, Science
Excerpts: A central principle of genetics is that cells within an organism contain the same complement of chromosomes. The presence of too many or too few chromosomes, called aneuploidy, is associated with disease, and accounts for the majority of spontaneous miscarriages in humans, as well as hereditary birth defects such as Down syndrome. Aneuploid cells try to compensate for the gene imbalance by increasing protein turnover, which requires more energy and slows down proliferation. Cancer cells somehow overcome the antiproliferative effect of aneuploidy.
Nanotubes Guide Phonons With Ease - Heat Could Be Used To Transmit Data, PhysicsWorld
Excerpts:  Scanning electron microscope image of a boron nitride nanotube in the Berkeley test fixture. The nanotube at the centre of the image is bent by pushing the pads (left and right) closer together as shown in the inset. (Courtesy: Chih-Wei Chang) |
Tiny nanotubes made of carbon or boron nitride can act as phonon waveguides and retain their excellent heat transmission properties even when they are severely distorted, report physicists in the US. The researchers believe that the discovery could lead to the development of communications systems that use phonons to transmit information along nanotubes - in much the same way as light is used to carry data through optical fibres.
Opaque Lens Focuses Light, PhysicsWorld
Excerpts:  Normally (a) a wavefront in a laser beam would scatter in all directions as it passes through an opaque sample, producing a speckled pattern of light on a screen. But in Mosk and Vellekoop's technique (b) the wavefront is split into segments, and the phase each of these is altered to pre-empt the scattering so that they all arrive at a single point in-phase. The trick is to know how the ¡§complex amplitude¡¨ of each segment's field will be affected as it passes through the sample. Without altering any, these amplitudes - the thick arrows in (c) - will all add randomly so that much of the total field cancels-out. But by even altering the phase of just one segment - the short dashed arrow - this destructive effect can be reduced (d). (Credit: Ivo Vellekoop and Allard Mosk) |
You might expect that an opaque material will always hinder the transmission of light by absorbing or scattering any light that is shone on it. But by carefully preparing a beam of laser light, physicists in the Netherlands have managed to use scattering in opaque materials to focus the light to an intensified point. Their technique could be used to obtain optical images of biological samples that are hidden beneath layers of opaque tissue. (...) The crucial part of Mosk and Vellekoop's technique is their computer program, which reads the intensity of the light hitting the camera and makes corrections to the LCD's pattern to make this intensity as large as possible.
Robot Wars Are A Reality, Guardian
Excerpts: In reality, a robot could not pinpoint a weapon without pinpointing the person using it or even discriminate between weapons and non-weapons. I can imagine a little girl being zapped because she points her ice cream at a robot to share. Or a robot could be tricked into killing innocent civilians. In attempting to allay political opposition, the US army is funding a project to equip robot soldiers with a conscience to give them the ability to make ethical decisions. But machines could not discriminate reliably between buses carrying enemy soldiers or schoolchildren, let alone be ethical. It smells like a move to delegate the responsibility for fatal errors on to non-sentient weapons.
Complex Challenges: Global Terrorist Networks
Group Rules Out Detainee Methods - Psychologists Call Usage Damaging, Washington Post
Excerpts: The American Psychological Association ruled yesterday that psychologists can no longer be associated with several interrogation techniques that have been used against terrorism detainees at US facilities because the methods are immoral, psychologically damaging, and counterproductive in eliciting useful information. Psychologists who witness interrogators using mock executions, simulated drowning, sexual and religious humiliation, stress positions, or sleep deprivation are required to intervene to stop such abuse, to report the activities to superiors, and to report the involvement of any other psychologists in such activities to the association.
Take Al Qaeda to Court, NY Times
Excerpts: Those who commit terrorist acts should be tried as the criminals they are, instead of the "warriors¡" they claim to be. If the Guantanamo detainees were prosecuted in federal courts instead of being designated as "combatants," (...). While being held in military custody, Jose Padilla was denied due process for more than three years because of assertions that his case was too difficult or sensitive for the federal courts. His conviction last week demonstrated otherwise. The transfer of his case to a federal court could have and should have occurred much earlier.
Management Of Natural And Bioterrorism Induced Pandemics, Bioethics
Excerpt: A recent approach for bioterrorism risk management calls for stricter regulations over biotechnology as a way to control subversion of technology that may be used to create a man-made pandemic. This approach is largely unworkable given the increasing pervasiveness of molecular techniques and tools throughout society. Emerging technology has provided the tools to design much deadlier pathogens but concomitantly the ability to respond to emerging pandemics to reduce mortality has also improved significantly in recent decades. In its historical context determining just how 'risky' biological weapons is an important consideration for decision making and resource allocation. (...)
