From Reuters, Automatic Trading Linked to News Events, NY Times
Excerpts: The news can be pretty hard on stock prices.
Announcements about corporate profits (or lack thereof), a change in management, rumors of a merger, even the weather. All these events can cause a company's share price to move wildly up or down.
Today, the Reuters Group begins selling two trading services that allow subscribers to set up automatic trading orders based on the news. They will give subscribers the ability to mine past and present Reuters news articles in real time and automatically buy, sell or hold a stock based on market-moving events.
And Now a Syllabus for the Service Economy, NY Times
Excerpts: To help prepare university students for the new services-based economy, I.B.M. wants colleges to teach services as a science.
A. Information technology is becoming embedded in all aspects of business, society and our personal lives. We see an increasing requirement to apply technology, engineering and disciplined thinking and design to the people aspect of businesses. That's really what we mean by services.
There are no universities that have had programs in applying technology to the people aspect of businesses.
The Predator's Gaze - Scientists Explore The Frightening World Of Psychopaths, Science
Excerpts: Not all psychopaths resort to violence, however. Highly intelligent people with psychopathic personalities find fertile, nonviolent opportunities in conning and manipulating others, in Porter's view.
There's currently a bull market in corporate psychopaths, (...).
In today's rapidly changing business world, "increased corporate rewards for risk taking and nonconformity can offer the psychopath faster career movement than before," (...).
(...) the more callous and unemotional a boy was, the more likely he was to respond well to rewards and encouragement from parents for good behavior, but not to punishments for misbehavior.
Self-organizing Social Hierarchy and Villages in a Challenging Society, Physica A
Abstract: We show by Monte Carlo (MC) simulation that the hierarchy and villages emerge simultaneously in a challenging society when the population density exceeds a critical value. Our results indicate that among controlling processes of diffusion and fighting of individuals and relaxation of wealth, the trend of individuals challenging to stronger neighbors plays the pivotal role in the self-organization of the hierarchy and villages.
Designing Complex Networks, arXiv
Excerpt: We suggest a new perspective of research towards understanding the relations between structure and dynamics of a complex network: Can we design a network, e.g. by modifying the features of units or interactions, such that it exhibits a desired dynamics? Here we present a case study where we positively answer this question analytically for networks of spiking neural oscillators. (...)
Correlations Between Structure and Dynamics in Complex Networks, arXiv
Excerpt: Previous efforts in complex networks research focused mainly on the topological features of such networks, but now also encompass the dynamics. In this Letter we discuss the relationship between structure and dynamics, with an emphasis on identifying whether a topological hub, i.e. a node with high degree or strength, is also a dynamical hub, i.e. a node with high activity. (...)
Priming Effects In Complex Information Environments, J. Politics
Excerpts: This paper revisits the original psychological literature on priming in order to assess new possibilities for research on priming effects stimulated by news discourse. We detail some important theoretical limitations of existing priming research; propose a method for studying the dynamics of priming effects in real-world, complex information environments; and illustrate the usefulness of this approach with a case study of opinion change during the 1990-91 Persian Gulf Crisis. This case study documents for the first time the daily dynamics of priming effects in a complex information environment (...).
Mileage From Megawatts: Study Finds Enough Electric Capacity To 'Fill Up' Plug-In Vehicles Across Much Of The Nation, Physorg.com
Excerpts: If all the cars and light trucks in the nation switched from oil to electrons, idle capacity in the existing electric power system could generate most of the electricity consumed by plug-in hybrid electric vehicles. A new study for the Department of Energy finds that "off-peak" electricity production and transmission capacity could fuel 84 percent of the country's 220 million vehicles if they were plug-in hybrid electrics.
Why A Hydrogen Economy Doesn't Make Sense, Physorg.com
In a recent study, fuel cell expert Ulf Bossel explains that a hydrogen economy is a wasteful economy. The large amount of energy required to isolate hydrogen from natural compounds (water, natural gas, biomass), package the light gas by compression or liquefaction, transfer the energy carrier to the user, plus the energy lost when it is converted to useful electricity with fuel cells, leaves around 25% for practical use ¡X an unacceptable value to run an economy in a sustainable future. Only niche applications like submarines and spacecraft might use hydrogen. (...)

Deep Thunder increases the resolution by using a mini-supercomputer to include additional information about the local area that can affect weather conditions. Geographical information about the local area (such as the topographic layout of the metropolitan area) and coastal information (such as the city's exposure) is fed into the supercomputer. "The differences are subtle, but at a local level they may be important," says Treinish. "The way thunderstorms occur in New York is different from the way they occur in Miami."
IBM has launched a new one-kilometer-resolution weather-forecasting service. This image shows that while some parts of Chicago were hit by severe thunderstorms (blue regions), other parts got off scot-free. Credit: IBM Research
NASA Plans Permanent Moon Base: Wants New, Self-Sustaining Colony As A Stepping Stone To Mars, vnunet.com
Excerpts: NASA officials have announced plans to build a permanently inhabited base on the moon. The space agency is appealing to international organisations and commercial space companies to help build the base. The plans call for building to begin by 2020 and the base to be permanently occupied and self sufficient by 2024. (...) The base will be at one of the moon's poles, which enjoy good access to the sunlight needed for solar power. NASA has also detected unusual amounts of hydrogen at the poles, suggesting water may be there which could be converted into hydrogen for power and oxygen for survival. (...)
Do Galaxies Follow Darwinian Evolution?, Innovations-report
Excerpts: (...) astronomers have shown the strong influence the environment exerts on the way galaxies form and evolve. The scientists have for the first time charted remote parts of the Universe, showing that the distribution of galaxies has considerably evolved with time, depending on the galaxies' immediate surroundings. This surprising discovery poses new challenges for theories of the formation and evolution of galaxies. The 'nature versus nurture' debate is a hot topic in human psychology. But astronomers too face similar conundrums, in particular when trying to solve a problem that goes to the very heart of cosmological theories (...)
The projector developed at Microvision is composed of two main parts: a set of red, blue, and green lasers made of semiconductor material, such as gallium indium arsenide, and a mirror--one millimeter across--that tilts on two axes. The lasers shine on the mirror, and the mirror reflects the pixel of light onto a wall or other surface. The intensities of the lasers change to produce different colors: when all three are pumping out light full blast, the pixel is white; when all three are off, the pixel is black. Other colors are produced from various combinations in between.

Structure Essential For Brain Remodeling Identified, Innovations-report
Excerpts: During learning and memory formation, the brain builds or remodels tiny structures on the surface of its nerve cells to store the new information. Now, a team led by Duke University Medical Center researchers has discovered where the brain gets the raw materials for such construction -- and has even taken "home movies" of the process. The discovery, made in rodents, may lead to advances in understanding Alzheimer's disease, autism and age-related memory loss, and could point to potential treatments for these and other neurological conditions, said senior study investigator (...).
Tracing The Formation Of Long-Term Memory, ScienceDaily
Excerpts: The formation of long-term memory in fruit flies can be demonstrated by the influx of calcium into cells called mushroom body neurons that occurs after special training that includes periods of rest, said researchers (...). "We have strong evidence that this is really a molecular change that is involved in long-term memory," said Dr. Ronald Davis (...). (...) used spaced training to teach the flies to associate an odor with a mild electric shock. This method gives the fly a training trial, then a rest and then another trial. The rest is critical in inducing long-term memory that can last days. (...)
Brain Wave Changes In Adolescence Signal Reorganization Of The Brain, ScienceDaily
Excerpts: Brain wave changes in adolescence are related to age, not sexual maturation, and may be associated with one of the brain's major reorganization projects: synaptic pruning, a new study finds. (...) In childhood, the brain has many synapses -- small junctions between neurons that transmit signals. The more junctions there are, the more intense the brain activity. During adolescence, the brain reorganizes and eliminates many synaptic connections, a process known as synaptic pruning. This pruning makes the brain's information processing more efficient and powerful while consuming less energy. (...)
Why Bonobos Make Love, Not War, New Scientist
Excerpts: When communities of bonobos from different areas of a forest meet, the females of each tribe initiate sex with males from the other. When chimp tribes meet, the encounters are extremely violent and it isn't unusual for at least a few individuals to end up mauled or even dead. Chimps create despotic male-controlled societies where males beat up females to display dominance. Bonobo society is egalitarian, until it is time to feed, at which point females tend to get preferential access. Tool use is another huge disparity between the two species.
Study Detects Recent Instance of Human Evolution, NY Time
Excerpts: A surprisingly recent instance of human evolution has been detected among the peoples of East Africa. It is the ability to digest milk in adulthood, conferred by genetic changes that occurred as recently as 3,000 years ago, a team of geneticists has found.
finding is a striking example of a cultural practice ¡X the raising of dairy cattle ¡X feeding back into the human genome. It also seems to be one of the first instances of convergent human evolution to be documented at the genetic level. Convergent evolution refers to two or more populations acquiring the same trait independently.
Understanding The Swing Of Things, New Scientist
Excerpts: The weird hotspots that Sievers sees with his pendulums have also turned up in substances ranging from helium to uranium. These strange, compact forms - sometimes known as discrete breathers for their localised fluctuating character - may just open a new chapter in the physics of solid matter.
For it seems increasingly likely that breathers contribute to almost everything that goes on in solids - from the flow of heat or electricity to the way materials expand or contract as they change temperature.
Scientists Learning To Create Nanomaterials Based On Micro-Algae Patterns, Spacemart.com
Researchers at the Georgia Institute of Technology have developed a technique to study how unicellular micro-algae, known as diatoms, create their complex cell walls. Researchers hope to learn how diatoms assemble these nanometer-patterned, intricate micro-architectures to find better methods for creating nanomaterials in the laboratory. "Diatoms are nature's most gifted nanotechnologists," said Nils Kroger, an assistant professor in Georgia Tech's School of Chemistry and Biochemistry and the School of Materials Science and Engineering. "We want to learn how diatom cell walls are produced because human technology can't make something that intricate by self-assembly processes and under ambient conditions."
Researchers hope to find better methods for creating nanomaterials based on intricate cell-wall patterns assembled by diatoms, such as Thalassiosira pseudonana./div>
NYU Chemists Create 'Nanorobotic' Arm To Operate Within DNA Sequence, EurekAlert
Excerpts: ¡§It is crucial for nanorobotics to be able to insert controllable devices into a particular site within an array, thereby leading to a diversity of structural states,¡¨ explained Seeman. ¡§Here we have demonstrated that a single device has been inserted and converted at a specific site.¡¨
added that the results pave the way for creating nanoscale ¡§assembly lines¡¨ in which more complex maneuvers could be executed.
Milk Therapy - Breast-Milk Compounds Could Be A Tonic For Adult Ills, Science News
It turned out to be the protein alpha-lactalbumin. But the compound becomes lethal only when exposed to acid, as it is in a stomach and was in the lab. The acid unfolds the alpha lactalbumin protein into a havoc-wreaking form.
ATTACK THWARTED. Bacteria that can cause pneumonia attack a throat cell (top) by attaching to sugar chains on the cell. In a solution of oligosaccharides¡Xindigestible sugars contained in breast milk¡Xthe pneumococci bind to the sugars and don't latch on to the throat cell (bottom). B. Andersson
nborg dubbed the acidified form of the protein HAMLET, for human alpha-lactalbumin made lethal to tumors.
cer cells take up far more HAMLET than healthy cells do. The huge quantities of unfolded proteins destroy the cancer cells.
Natural Protein Stops Deadly Human Brain Cancer In Mice, Johns Hopkins Medicine News
Excerpts: Treatment targets stem-cell-like clusters that develop into cancer Scientists from Johns Hopkins and from the University of Milan have effectively proven that they can inhibit lethal human brain cancers in mice using a protein that selectively induces positive changes in the activity of cells that behave like cancer stem cells. The report is published this week in Nature.
The most common type of brain cancer-glioblastoma-is marked by the presence of these stem-cell-like brain cells, which, instead of triggering the replacement of damaged cells, form cancer tissue.
Silica Particle Sparks Life In Protein, Physorg.com
Excerpts: Tiny formless particles in water solution take on a well-ordered and functional structure as soon as they come into contact with nanoparticles of silica. A unique breakthrough by researchers at Linkoping University in Sweden creates new potential in medicine and biochemistry and at the same time provides a new piece of the puzzle in theories about the origins of life.
mally, inorganic materials like silica are unwelcome in biological systems, since they disrupt the form and function of proteins.
Bio-Ink Printer Makes Stem Cells Differentiate, New Scientist
Excerpts: An inkjet device that prints tiny ¡§bio-ink¡¨ patterns has been used to simultaneously grow two different tissues from the stem cells of adult mice. Surgeons could one day use the technology to repair various damaged tissues at the same time, the researchers say.
Inkjet technology uses a fine stream of droplets to build structures and is employed across many industries - from computer chip design to large scale manufacturing.
This Is Your Country on a Blue State Binge, NY Times
Excerpts: We know that Congress has turned blue, but which parts of the country have turned the bluest? Based on voting in House races, the Northeast and Ohio River valley have seen the greatest indigo infusions ¡X and indeed those are the regions where the Democrats cemented their House takeover.
Still, in all but three states last month, more people voted for Democrats in House races than in 2004, even when the totals were adjusted to account for the disparity between higher-turnout presidential years and midterms.
Changes Are Expected in Voting by 2008 Election, NY Times
Excerpts: By the 2008 presidential election, voters around the country are likely to see sweeping changes in how they cast their ballots and how those ballots are counted, including an end to the use of most electronic voting machines without a paper trail, federal voting officials and legislators say.
Complex Challenges: Global Terrorist Networks
U.S. to Expand Cargo Scans to Detect Nuclear Material, NY Times
Excerpts: All cargo sent by container ships to the United States from three ports - in Pakistan, Honduras and Southampton, England - will be scanned for hidden nuclear weapons or components starting next year under a federal antiterrorist program that some in Congress want to see mandated worldwide.
program, called the Secure Freight Initiative, will require United States-bound containers before departure to pass through both a radiation detection machine and an X-ray device, a combination intended to find bomb-making materials that have intentionally been shielded.
Open-Source Spying, NY Times
When Matthew Burton arrived at the Defense Intelligence Agency in January 2003, he was excited about getting to his computer. Burton, who was then 22, had long been interested in international relations: he had studied Russian politics and interned at the U.S. consulate in Ukraine, helping to speed refugee applications of politically persecuted Ukrainians. But he was also a big high-tech geek fluent in Web-page engineering, and he spent hours every day chatting online with friends and updating his own blog. (Contributed by Irene Sanders)

Annan Urges U.S. to Reject Unilateralism, NY Times
Excerpts: Kofi Annan, the departing secretary general of the United Nations, challenged the Bush administration yesterday to shun go-it-alone diplomacy and remain committed to observing human rights as it acts to forestall terrorism.
a speech delivered at the Truman Presidential Museum and Library in Independence, Mo., billed as his last address to an American audience as secretary general, Mr. Annan said, ¡§You Americans did so much, in the last century, to build an effective multilateral system, with the United Nations at its heart. Do you need it less today, and does it need you less than 60 years ago?¡¨

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