Biodiversity Science Evolves, Science
Excerpts: The planet's biodiversity is increasingly threatened by human activities. We have heard this before, and the global mantra to stop the damage has forged numerous international panels and agreements over the past 15 years. Yet despite these efforts to ensure biodiversity conservation, we have witnessed extensive population extinctions and massive deforestation and fragmentation of natural habitats, and we may even see the geographic contraction of major ecosystems, such as the tropical rainforest in its northernmost distribution in the Americas.
Pattern-Oriented Modeling of Agent-Based Complex Systems: Lessons from Ecology, Science
Excerpts: Agent-based complex systems are dynamic networks of many interacting agents; examples include ecosystems, financial markets, and cities. The search for general principles underlying the internal organization of such systems often uses bottom-up simulation models such as cellular automata and agent-based models. No general framework for designing, testing, and analyzing bottom-up models has yet been established, but recent advances in ecological modeling have come together in a general strategy we call pattern-oriented modeling.

What Lurks in Its [Google's] Soul?, Washington Post
Excerpts: The soul of the Google machine is a passion for disruptive innovation. Powered by brilliant engineers, mathematicians and technological visionaries, Google ferociously pushes the limits of everything it undertakes. The company's DNA emanates from its youthful founders, Sergey Brin and Larry Page, who operate with "a healthy disregard for the impossible," as Page likes to say. Their goal: to organize all of the world's information and make it universally accessible, whatever the consequences.
Excerpts: One of the most exciting Google projects involves biological and genetic research that could foster important medical and scientific breakthroughs. Through this effort, Google may help accelerate the era of personalized medicine, in which understanding an individual's precise genetic makeup can contribute to the ability of physicians and counselors to tailor health care treatment, rather than dispensing medications or recommending treatments based on statistics or averages. New insights, new medicines, and the use or avoidance of certain foods and pharmaceuticals for people with specific genetic traits are among the possible outcomes.
Excerpts: Each innovation on its own has a small impact, but the many new initiatives add up to strong growth in sales and earnings. (...)
Bottom-up innnovations often reflect a deep operational understanding of the business and its current customers. The innovations coming top-down reflect strategic decisions made by the company's senior executives.
These two approaches are not mutually exclusive, and most companies will want to use some combination of both.
Top-down innovation can crowd out the bottom-up kind, however, leading a company to reject worthy innovations because they did not originate at the top.
Sense-And-Respond Grids For Adaptive Enterprises, IT Professional
Abstract: In order to adapt to complex interactions among customers, suppliers, manufacturers, markets, and other elements of their businesses, enterprises must strive for maximum responsiveness. Many firms have typically relied on the sense-and-respond paradigm for monitoring and managing business solutions. But a new breed of platforms and tools that use the S&R paradigm are making it possible to build an effective decision-making process into an enterprises' software and equipment. In this article, the authors discuss S&R grids and give working examples of how S&R systems can help manage business activities

Insanity and imagination often seem to go hand-in-hand, but is there really a link between the two? A new study suggests there is by showing that hyperactive and bipolar children score higher on an index of creativity than their normal peers. Because these children also have parents who are bipolar, the findings indicate there may be a genetic connection between psychosis and creativity.

High testosterone levels can turn men into aggressive bullies, but a new study finds that low levels may transform them into cuddly daddies. Married men were found to have less testosterone than single men, and even less once a baby arrived.

Don Juans and dead-beat dads give men a bad rap, considering that the males of 95% of mammal species never pair-bond or help raise young. What is it that makes men as caring as they are? One theory holds that testosterone is the key.
Parents Carry Burden of Proof in School Cases, Court Rules, NY Times
Excerpts: There are nearly seven million students in the country who receive special education services under the Individuals With Disabilities Education Act, which in several earlier forms dates from 1970. To fulfill the law's requirement to provide a "free appropriate public education," school districts work with parents to develop an individual program for each student with a disability. Depending on the child's needs, the program can provide anything from a weekly session with a speech teacher to placement at taxpayer expense in a private residential program.
Editor's Note: This decision will shift the balance of where parents will claim that their child has a disability, an adaptive process in a society where classifications like ˇ§disabledˇ¨ can have profound impacts on education and later professional careers.
Y Did the Chromosome Cross the Road?, Science Now
Are women easier to please than men? It may be true for jokes. Researchers have discovered that humor activates the reward system in women's brains more than it does in men's.

Men and women behave differently when it comes to humor. Women seem to laugh a little louder at parties and tend to think a sense of humor is more important in a potential mate than physical appearance is. Researchers have been looking for a neurological basis for this but have been unsuccessful.
PET Imaging Reveals the Immune System at Work, HHMI News
Excerpts: For clinicians, the ability to look routinely inside the body and see ˇX at the level of the cell ˇX how it confronts disease is a distant dream.
But in a series of experiments with genetically engineered mice, a team of researchers from the Howard Hughes Medical Institute (HHMI) at the University of California Los Angeles has taken a key step toward realizing that vision by demonstrating the ability to peer inside the body non-invasively and see the immune system at work.
Neurobiology: Triggers For Channel Opening, Nature
Excerpts: Chemical signalling in the brain involves the rapid opening and closing of channels known as ligand-gated ion channels, which lie in the membranes of nerve cells. Binding of a specific activator (a ligand) to these proteins triggers the opening of an integral pore through the membrane in as little as tens of microseconds1. Although we know a fair amount about the structure of ligand-gated ion channels, the mechanisms by which the binding of a ligand triggers channel opening are still under debate.
Circadian Rhythms: Clock Coordination, Nature
Excerpts: Many animals concentrate their activity around dawn and dusk. This timing is regulated by distinct 'morning' and 'evening' oscillators in the central nervous system. But how are these two neuronal clocks coordinated?
Where Did Europeans Come From?, Science Now
Europe is home to 700 million people, but where did this population get its start? Some argue that modern Europeans are mostly descended from farmers who moved in from Greece and the Near East more than 8000 years ago, while others say their ancestors were primarily Paleolithic hunter-gatherers who arrived on the continent as long as 40,000 years ago. Now, a new DNA analysis of early Europeans indicates that the Paleolithic theory may be correct, but some critics are still not convinced.

Water Builds The Heat In Europe, BBC News
Excerpts: Water vapour rather than carbon dioxide in the atmosphere is the main reason why Europe's climate is warming, according to a new study. The scientists say that rising temperatures caused by greenhouse gases are increasing humidity, which in turn amplifies the temperature rise.
Abstract: Complex evolving systems, consisting of populations of varied and replicating entities are found in both nature and human society. There exists no alternative to the core Darwinian principles of variation, selection and inheritance to explain the evolution of such systems. Neither the actual existence of human intentionality nor the hypothetical possibility of Lamarckian acquired character inheritance offers a barrier to the use of Darwinian principles. On the contrary, Darwinism is always required to complete the explanation. However, while Darwinian principles are always necessary to explain complex evolving population systems they are never sufficient on their own.
The Role of Redundancy in the Robustness of Random Boolean Networks, arXiv
Abstract: Evolution depends on the possibility of successfully exploring fitness landscapes via mutation and recombination. With these search procedures, exploration is difficult in "rugged" fitness landscapes, where small mutations can drastically change functionalities in an organism. Random Boolean networks (RBNs), being general models, can be used to explore theories of how evolution can take place in rugged landscapes; or even change the landscapes.
In this paper, we study the effect that redundant nodes have on the robustness of RBNs. Using computer simulations, we have found that the addition of redundant nodes to RBNs increases their robustness. We conjecture that redundancy is a way of "smoothing" fitness landscapes. Therefore, redundancy can facilitate evolutionary searches. However, too much robustness could reduce the rate of adaptation of an evolutionary process.
Evolution Of Host Resistance: Looking For Coevolutionary Hotspots At Small Spatial Scales, Proc. Biol. Sc.
Excerpts: Natural plant populations are often found to be extremely diverse in their resistance to pathogens. While the potential of pathogens in driving the evolution of resistance in hosts has been widely recognized, empirical evidence linking disease dynamics to host population genetic structure has remained scarce. Here I show that current coevolutionary selection for resistance can be divergent even on a very fine spatial scale. In a natural plant-pathogen metapopulation, disease occurrence patterns were highly aggregated over space and time within host populations. A laboratory inoculation experiment showed higher resistance (...).
The Hasty Bee Gets More Nectar, Science
Slow and steady may have helped the tortoise win the race, but bumblebees do better following the hare's impulsive strategy. Bees that forage for nectar hastily collect food faster than bees that carefully seek out flowers containing nectar, according to a new study.

Scientists typically measure the success of foraging insects by judging how frequently the creatures identify a suitable food source. But evolutionary ecologist James Burns of the University of Toronto, Canada, saw a flaw in this approach: Might a bee collect more nectar if it indiscriminately visits lots of flowers instead of taking the time to evaluate each one?
Bees Solve Complex Colour Puzzles, ScienceDaily
Excerpts: Bees have a much more sophisticated visual system than previously thought, according to a new UCL (University College London) study in which bees were able to solve complicated colour puzzles. The findings shed light on how brains resolve one of the most difficult challenges of vision - namely, recognizing different surfaces under different colours of illumination - by suggesting that bees solve this problem using their experience with meaningful colour relationships between objects in a scene. (...) trained bumblebees to find artificial flowers of a particular colour using a nectar reward. (...)
Fungi 'New Tool' Against Malaria, BBC
(...) specific type of fungus native to East Africa can infect mosquitoes and reduce their lifespan by two-thirds - to just seven days.
Mosquitoes are unlikely to develop resistance to the fungi, say scientists
Professor Willem Takken from Wageningn University in the Netherlands said the fungus also stops live mosquitoes from transmitting the malaria parasite to humans.
"The minute a mosquito becomes infected it basically stops its blood-feeding behaviour," he said.
"It seems as if it is no longer hungry. It will still take some water or any other juice but no longer blood.
Think Like A Parasite, Science Now
A malaria vaccine that imitates the parasite's effects on the human immune system has shown promise in its first human tests. Although the vaccine is a long way from protecting people in malaria-endemic areas, scientists say the unusual approach is paying off.

The malaria parasite, one of the world's biggest killers, is a devilishly difficult target for vaccines. Its complex lifestyle and its large genome mean that it can easily evade most antibodies that vaccines prompt the body to produce.
Evolution: The Tree-Thinking Challenge, Science
Excerpts: The central claim of the theory of evolution as laid out in 1859 by Charles Darwin in The Origin of Species is that living species, despite their diversity in form and way of life, are the products of descent (with modification) from common ancestors. To communicate this idea, Darwin developed the metaphor of the "tree of life." In this comparison, living species trace backward in time to common ancestors in the same way that separate twigs on a tree trace back to the same major branches. Coincident with improved methods for uncovering evolutionary relationships, evolutionary trees, or phylogenies, have become an essential element of modern biology (1)).
Massive chunks of ice that blocked migration routes sped up the evolution of some Antarctic penguins. That's one theory biologists are putting forward to explain a striking number of genetic differences between modern members of this group and their 6000-year-old ancestors, whose DNA has been recovered from an ancient Antarctic nesting site.

Ancient DNA is a potential gold mine for biology. It allows scientists to directly trace evolution over thousands of years.
Dodging Doomsday With A Space Tug, Science Now
Preventing an asteroid from slamming into Earth may not require Hollywood bravado. Two NASA astronauts have hit upon an idea wherein a spacecraft uses gravity to literally tow a threatening projectile into safer orbit.

Strategies for defending Earth from incoming celestial objects run the gamut from a quick smash to a slow shove. Some have suggested ramming an asteroid with a bomb or heavy projectile, but this could actually compound the problem by fracturing the object into pieces, some of which could still hit Earth.
Gravitational Tractor For Towing Asteroids, Nature
Excerpts: A spacecraft could deflect an Earth-bound asteroid without having to dock to its surface first.
We present a design concept for a spacecraft that can controllably alter the trajectory of an Earth-threatening asteroid by using gravity as a towline. The spacecraft hovers near the asteroid, with its thrusters angled outwards so that the exhaust does not impinge on the surface. This proposed deflection method is insensitive to the structure, surface properties and rotation state of the asteroid.
Science To Ride Gravitational Waves, BBC News
Many expect it to be one of the biggest scientific breakthroughs of our age: "There'll certainly be a Nobel Prize in it for somebody," says Jim Hough.

The UK professor is standing on a farm road in Lower Saxony, Germany, with a crop of beet on one side and sprouts on the other.
But the real interest lies at his feet - with some shabby, corrugated metal sheeting. For a moment, it looks like an upturned pig trough until you realise it stretches for hundreds of metres.
Surprise Neutron Star Suggests Black Holes Are Hard To Make, Science
Excerpts: Black holes may be harder to create than previously believed, according to an unexpected discovery made with NASA's Chandra X-ray Observatory. Researchers have long thought that any star more than 25 times the mass of our sun will end its life as a black hole. But Chandra's finding suggests that even a star of 40 solar masses may fail to create one. Because such massive stars are extremely rare, that raises the question of how stellar black holes form at all. "It's a surprising find," says Gertjan Savonije of the University of Amsterdam, the Netherlands.
Seeing Mountains In Starry Clouds Of Creation, NY Times
These pillars, at heights up to 40 light-years, are 10 times as large as those in the famous Hubble image.
An infrared image of emerging stars captured by the Spitzer Space Telescope.
The astronomers, led by Lori E. Allen of the Harvard-Smithsonian Center for Astrophysics, say the towering mountains of the new image probably represent the densest, most fecund remnants of a larger, cloud. It is being eroded by radiation and winds of particles from a ferociously bright star just out of the top of the picture.
Nestled within the dusty pillars are hundreds of embryonic stars.
Materials Science: Erasing Electron Mass, Nature
Excerpts: Two-dimensional graphite could be useful in carbon-based electronic devices. How electrons move in these structures seems best described by relativistic quantum physics, modelling them as if they have no mass at all.
(...) in the honeycomb structure of graphene, the relation between energy and momentum of the conduction electrons is linear (...). This is reminiscent of Einstein's theory of relativity for massless particles - which travel at the speed of light - and suggests that electrons in graphene obey a two-dimensional version of the relativistic quantum theory introduced by Paul Dirac in 1928.
Self-Organized Control of Irregular or Perturbed Network Traffic, arXiv
Abstract: We present a fluid-dynamic model for the simulation of urban traffic networks with road sections of different lengths and capacities. The model allows one to efficiently simulate the transitions between free and congested traffic, taking into account congestion-responsive traffic assignment and adaptive traffic control. We observe dynamic traffic patterns which significantly depend on the respective network topology. Synchronization is only one interesting example and implies the emergence of green waves. In this connection, we will discuss adaptive strategies of traffic light control which can considerably improve throughputs and travel times, using self-organization principles based on local interactions between vehicles and traffic lights. Similar adaptive control principles can be applied to other queueing networks such as production systems. In fact, we suggest to turn push operation of traffic systems into pull operation: By removing vehicles as fast as possible from the network, queuing effects can be most efficiently avoided. The proposed control concept can utilize the cheap sensor technologies available in the future and leads to reasonable operation modes. It is flexible, adaptive, robust, and decentralized rather than based on precalculated signal plans and a vulnerable traffic control center.
Report: This is a follow-up report on In Calcutta, Rickshaw Drivers Approach The End Of The Road (see
ComDig 2005.45.8.1 ). Basically there are two types of rickshaws in Calcutta. First type is those which are directly pulled by a man- called 'tana' (meaning pulled) in Bengali language( see pictures). The other type is called cycle-rickshaw. The later type is very popular here and is large in number. The former type is found only in restricted parts of Calcutta, and is not used even in other parts of the state. The plan of the government is terminate the pulled rickshaws. While noting the fact that both the types are slow moving, strong public opinion is against continuing pulled rickshaws.
For ComDig I interviewed Mr. Bikas R. Bhattacharya, Mayor of Calcutta who explained the situation in details. In another interview (in Bengali language), a local politician, Mr. Buddhadev Bose, holding a position in the city politics, also supported the move of the government as the pulled rickshaws are inhuman in his view where a man is carrying another man. But, he as well as the Mayor of Calcutta expects some compensation for those who will loose their jobs. No major organization, party in Calcutta is against the government move- at least in the public eye.
Complex Challenges: Global Terrorist Network
Analysis: Zarqawi's Expanding Terror Network, UPI/World Peace Herald
Excerpts: A statement on an Islamist Web site in which al-Qaida claimed responsibility for the attacks said the three hotels - (?) -- were targeted because King Abdullah, the Jordanian ruler had turned them into "a backyard for the enemies of the faith, the Jews and crusaders." But Zarqawi's attack misfired. Most of the victims who died when one bomber blew himself up in the middle of a wedding party at the Radisson were neither Jewish nor Westerners but native Jordanians and Palestinians residing in Jordan.
Prisoners Of The Senate, NY Times
Excerpts: That Senator Graham pressed to end what is often the Guant?namo prisoner's only chance for an unbiased look at his claims of innocence was something of a surprise. He has been a staunch supporter of the effort (...) to forbid cruel, inhuman and degrading treatment of detainees in American custody.
The McCain proposal passed the Senate by a vote of 90 to 9. But the Graham amendment would make its enforcement difficult if it became law. Without habeas corpus, there would be no meaningful forum to deal with mistreatment.
