Statistical Physics Predicts Stock Market Gloom, New Scientist
Excerpt: A statistical physics model is predicting that the US stock market recovery suggested by recent rises will only last until spring next year, before tumbling yet further. Physicists Didier Sornette and Wei-Xing Zhou at the University of California in Los Angeles claim to have identified an "anti-bubble" in the Standard and Poor's 500 stock market index. Their model also describes a similar anti-bubble in the Japanese Nikkei index in the early 1990s, which preceded a decade of decline.
Excerpt: Pay for performance has become one of the mantras of modern management, yet most rewards are based on current business, not exploration. To ensure profitability in the future, companies should balance their incentives so that they reward both success at the moment and innovation for the future, as well as group or company rather than individual achievement. In addition, employers should foster a culture of commitment to reassure employees that their long- term interests are aligned with those of the companies they serve.
The Wisdom of the Anthill, Business 2.0
Excerpts: An ant crawls out of its hill and marches toward a half-eaten Twinkie. Another treks to a puddle of water. Others plot routes to their own diminutive chores. Along the way, each lays down a pheromone trail that, over time, tells co-workers where it has been, what hazards to avoid, and which path offers the quickest way home. If ants can run efficient supply chains with brains that weigh less than the ink in this comma, why do we humans have such trouble?
School League Tables Are 'Meaningless', New Scientist
Excerpts: By sending virtual pupils to simulated schools, mathematicians have shown that league tables that rank schools on one year's exam results are deeply misleading. (...) used a simple mathematical model to simulate the effect of league tables on 10 schools attended by 4000 virtual pupils over 15 years - data that would have been extremely difficult to collect in the real world. Their results show that the position of a school in the league does not reflect the quality of the education it provides.
Google Display Shows What The World Is Thinking About, Mercury News/NYTimes
Excerpts: The projected display, called Live Query, shows updated samples of what people around the world are typing into Google's search engine. (...) Stare at Live Query long enough, and you feel that you are watching the collective consciousness of the world stream by. (...) Google's worldwide scope means the company can track ideas and phenomena as they hop from country to country.(...) Like a series of waves, Google searches for Las Ketchup undulated through Europe over the summer and fall, first peaking in Spain, then Italy, (...).
Fewer Media Owners, More Media Choices, NYTimes
Excerpts: Now the typical American can watch Britain's BBC News, among others, on television and choose from tens of thousands of news Web sites, from Al Jazeera, based in Qatar, to The Times of India, based in New Delhi. As a result, federal regulators are questioning whether fears of corporate media domination have become obsolete. The impact of the Internet and the expansion of cable and satellite TV will be discussed next month, as the Federal Communications Commission considers loosening ownership restrictions (...).
Bambi's Mother in the Cross Hairs, NYTimes
Excerpts: (...) slow the rapid expansion of deer populations that are devastating ecosystems in many areas of the country. At least 20 million white-tailed deer are ranging the nation at the moment, a huge jump from only 500,000 in 1900, (...). They plunder farm crops and alter the ecology of forests by eating the low-lying vegetation and destroying the seedlings needed for new growth. In the process, they displace many smaller animals from their habitat. (...) help spread Lyme and livestock diseases, and cause an astonishing number of highway accidents.
Spider And Fly Swap Roles, Nature
Excerpt: It seems suicidal. The fly zooms into the heart of a mass of spiders, and then to the centre of a web. This is cunning, not recklessness, ecologists have found. Twanging the web like a struggling insect, the fly lures the mother spider away from her clutch. The fly then nips in and lays a predatory grub on the eggs. The Mexican spider Metepeira incrassata builds its webs in colonies up to 100,000 strong and 160 metres long. To the fly Arachnidomyia lindae these are more creche than death-trap.
The Mouse Genome And The Measure Of Man, Science Daily
Excerpts: The international Mouse Genome Sequencing Consortium today announced the publication of a high-quality draft sequence of the mouse genome -- the genetic blueprint of a mouse -- together with a comparative analysis of the mouse and human genomes describing insights gleaned from the two sequences. (...) The achievement represents a landmark advance for the Human Genome Project. It is the first time that scientists have compared and contrasted the contents of the human genome with that of another mammal. This milestone is all the more significant given that the laboratory mouse is the most important animal model and is widely used in the study of human diseases
Studies Challenge Thinking on Irregular Heart Rhythm, NYTimes
Excerpts: Less costly and safer drugs that adjust the heart's rate are as effective as other drugs and procedures that control the heart's rhythm, (...). The rate therapy also led to fewer admissions to a hospital in the studies, (...). A complex electrical system controls each heartbeat. It starts with a charge in an atrium, an upper chamber of the heart, that passes through nerve fibers to the ventricles, the lower chambers, to produce a regular rhythm. The rate, or speed, varies with physical activity, emotions and stress.
Functional Integration And Inference In The Brain, Prog. in Neurobiol
Abstract: Self-supervised models of how the brain represents and categorises the causes of its sensory input can be divided into two classes: those that minimise the mutual information (i.e. redundancy) among evoked responses and those that minimise the prediction error. This review describes the two classes of models and their implications (...). The main point made in this review is that backward connections, mediating internal or generative models of how sensory inputs are caused, are essential if the process generating inputs cannot be inverted. Because these processes are dynamical in nature, sensory inputs correspond to a non-invertible nonlinear convolution of causes.
Inputs To And Outputs From The Mammalian Circadian Oscillators, Trends in Neurosc.
Abstract: Oscillating levels of clock gene transcripts in the suprachiasmatic nucleus (SCN) are essential components of the mammalian circadian pacemaker. Their synchronization with daily light cycles involves neural connections from light-sensitive photoreceptor (...). Many of the transcripts expressed rhythmically only in the SCN are involved in neurosecretion, and their secreted products could mediate SCN control over physiological rhythms by coordinating rhythmicity in other nuclei within the brain. The coordination of clock gene transcript oscillations in peripheral tissues could be controlled directly by specific signals or indirectly by rhythmic behavior such as feeding.
Search For Sympathy Uncovers Patterns Of Brain Activity, ScienceDaily
Excerpts: Neuroscientists trying to tease out the mechanisms underlying the basis of human sympathy have found that such feelings trigger brain activity not only in areas associated with emotion but also in areas associated with performing an action. The actors were videotaped telling the stories, which lasted one to two minutes, with three different expressions ¡V neutral, happy or sad. (...) as people watched the videos, different brain regions were activated depending on whether an actor's expressions matched the emotional content of the story. When the story content and expression were congruent, neural activity increased in emotional processing areas of the brain.
Laser Leads Nerve Growth, Nature
Excerpts: A laser beam can guide nerve cells to grow in a particular direction, researchers have shown. The technique might help damaged nerves to regrow or could connect them to electronic implants, such as artificial retinas and prosthetic limbs. Rat and mouse nerve cells growing over a glass plate take the path pointed out by a red laser, (...). The cells move towards the spot of laser light, travelling as if down a gentle slope, they think. Moreover, the laser does not harm the cells,(...)
Explaining The Nervous System In Terms Of Computer Programming, Cogprints
Abstract: It is argued that the key to understanding the brain is to view it as a device making extensive use of methodologies developed in computer programming, the idea of compiling source code written in a high-level language providing a mechanism for conceptually linking the two domains. Following the argument through, one arrives at a clarification of what the nervous system in its complexity is all about; it consists of a collection of devices for implementing specific kinds of competence, in ways in principle indicated in detail by application of the object- oriented programming paradigm to the various kinds of processes featuring in cognitive life.
Abstract: Insect navigation relies on path integration, a procedure by which information about compass bearings pursued and distances traveled are combined to calculate position. Three neural levels of the polarization compass, which uses the polarization of skylight as a reference, have been analyzed (...). Polarization-opponent neurons in the optic lobe condition the polarization signal by removing unreliable and irrelevant components of the celestial stimulus. Neurons found in the central complex of the brain possibly represent elements of the compass output. The odometer for measuring travelling distances in honeybees relies on optic flow experienced during flight, whereas desert ants most probably use proprioreceptive
Abstract: Severe size constraints are imposed on the hearing organs of insects, yet they perform sophisticated tasks of auditory processing. Recent research has shown how flies acoustically locate targets in space, how mosquitoes afford highly sensitive ears, and how crickets avoid deafening themselves with their songs. These findings unveil the exquisite analytical capabilities of highly specialized microscale auditory systems.
Cosmic Rays, Clouds, and Climate, Science
Excerpts: It has been proposed that Earth's climate could be affected by changes in cloudiness caused by variations in the intensity of galactic cosmic rays in the atmosphere. This proposal stems from an observed correlation between cosmic ray intensity and Earth's average cloud cover over the course of one solar cycle. (...) Nevertheless, the observation has raised the intriguing possibility that a cosmic ray-cloud interaction may help explain how a relatively small change in solar output can produce much larger changes in Earth's climate.
Outside-In: Clearing Up How Cloud Droplets Freeze
Excerpts: A fresh look at old experimental data is threatening to overturn a longstanding theory about how water droplets freeze within clouds. Suspended water droplets can remain liquid even when they and the air that surrounds them have temperatures far below the normal freezing point, says Azadeh Tabazadeh, an atmospheric chemist (...). Data collected in recent years show that clouds as cold as ¡V37.5¢XC can still contain many supercooled droplets. Such droplets freeze solid almost instantly if they bump into each other or are otherwise disturbed
Revolutionary New Theory For Origins Of Life On Earth, ScienceDaily
Excerpts: Research (...) claims that living systems originated from inorganic incubators - small compartments in iron sulphide rocks. Since the 1930s the accepted theories (...) - in essence - life first, cells second and the atmosphere playing a role. They claim that cells came first. The first cells were not living cells but inorganic ones made of iron sulphide and were formed not at the earth's surface but in total darkness at the bottom of the oceans. Life, they say, is a chemical consequence of convection currents through the earth's crust and in principle, this could happen on any wet, rocky planet.
New CU-NASA Research Belies Previous Idea That Mars Was Once Warm, Wet Planet, Science Daily
Excerpts: (...) Mars has been primarily a cold, dry planet following its formation some 4 billion years ago, making the possibility of the evolution of life there challenging at best. Led by CU-Boulder doctoral candidate Teresa Segura and her adviser, Professor Owen B. Toon, the team used Mars photos and computer models to show that large asteroids or comets hit the planet some 3.5 billion years ago. These impacts apparently occurred about the time major river channels were formed on the Red Planet, said Segura.
Human Genetics: Mystery Of The Mutagenic Male, Nature
Excerpts: Old fathers are the source of more genetic mutations in their offspring than either young fathers or mothers of any age. But the apparently most plausible explanation for this effect might not hold. Mutations are the raw material for evolution, and the cause of genetic disease. (...) A clue is the finding that fathers are the source of more mutations than mothers. The usual explanation is that the copying of DNA (replication) is error prone, and that women's reproductive cells suffer fewer such errors than men's.
Strong Magnets By Self-Assembly, Nature
Excerpts: Newly developed nanomaterials are proving useful in many fields, but materials that make strong permanent magnets are difficult to devise. Progress has been made using a self-assembled mixture of nanoparticles. Controlled structuring of materials at the nanoscale can enhance some of their properties and widen their range of applications. Magnetic materials, such as recording media, field sensors and memory devices, are advancing rapidly in terms of their miniaturization, sensitivity and other figures of merit. But progress in producing permanent magnets has been limited (...).
Excerpts: The robot that saved Deep Space One was in the vanguard of a new breed of machines poised to have a big impact in space and here on Earth. Quite unlike the metallic contraptions that march stiffly through sci-fi movies (...), the new robots have more brain than brawn. Each possesses a detailed picture of its own inner workings¡Xencoded in software-based models¡Xthat gives it the ability to respond in novel ways to events its programmers might not have anticipated.
Crichton's Prey Novel And Agent-Based Simulation Of Combat, Discussion
Excerpts: The reason I am emailing to you *today*, is that Crichton's Prey novel caught my attention (...). I am heading a project to develop an agent-based simulation of combat. Both the earlier "proof of concept" model (called ISAAC) and most recent version of EINSTein (which is in active development) are available on a CNA web page (...) (See movies ) (...) I will never forget the chilling thought that crossed my mind: what if, I asked myself, someone would marry my simple ISAACian "rules" (which, BTW, include a GA for the user to breed mission-tailored agent compositions - EINSTein has a more powerful version already built-in) with nano-scale, physical "robots"?
Swarming¡¨ Military Concepts and Capabilities, Meeting Announcement
Abstract/Excerpts: An inspiration borrowed from the animal kingdom, military swarming occurs when a collection of decentralized, often diverse units converge on an objective from multiple directions and re-disperse for future action. Swarming suggests the potential to rapidly concentrate the power of a highly networked force to dominate an adversary. Many of the most innovative ideas under consideration by the U.S. Department of Defense rely in some way on swarming concepts (e.g. network centric operations). On the other hand, many threats are much more dangerous when combined with even crude forms of swarming (e.g. coordinated acts of terrorism).
Complex Challenges: Global Terrorist Networks
Analysis: Tense Times For Saudi Arabia,, BBC News Online
Excerpts: Its lack of public support for US ambitions in Iraq puts Saudi Arabia on the wrong side of President George W Bush's "you are either with us of against us" formulation. So far, Riyadh has neither allowed US use of bases on its soil for a campaign against Iraq, nor absolutely discounted the possibility. The US Government still very publicly supports the relationship with the Saud family, and vice versa, because both elites know the value of the relationship at a strategic level - oil and regional security are extremely important
Judge Grants 'Combatant' Access to an Attorney, Washington Post
Excerpts: (...) government's argument that Padilla and other enemy combatants should have no access to an attorney, and that the order seemed to leave open the possibility of detailed review of the case by a federal court.(...) Lucas Guttentag, an attorney with the American Civil Liberties Union, which filed a brief on Padilla's behalf, called the decision "a critical repudiation of the Bush administration's claim of virtually unbridled power to unilaterally detain an American citizen and to hold him incommunicado indefinitely."
U.S. Can Target American Al-Qaida Agents, The Washington Post
Excerpts: American citizens working for al-Qaida overseas can legally be targeted and killed by the CIA under President Bush's rules for the war on terrorism, U.S. officials say. The authority to kill U.S. citizens is granted under a secret finding signed by the president after the Sept. 11 attacks that directs the CIA to covertly attack al-Qaida anywhere in the world. The authority makes no exception for Americans, so permission to strike them is understood rather than specifically described, officials said.
Tracking Six Legs Of Trouble, NYTimes
Excerpts: Dr. Melody A. Keena's enemy is armed with supersensitive detection devices and a pair of deadly pincers that can shear through the toughest armor. (...) an insect as dangerous as the Asian long-horned beetle, which her research has shown to be an even graver threat to $700 billion worth of hardwood trees in America's forests and cities than had been expected. Federal inspectors who watch for invaders like the beetle have even been drafted into the new Department of Homeland Security.
