Coping With Complexity, Nature
Excerpts: A more detailed understanding of scientific concepts does not lead to simplicity. (...)
For most geneticists, this complexity is a source of marvel and fascination - and employment. How dull their lives would be if, once the human genome had been sequenced, there were just genes and diseases to be linked, like one of those join-the-dots puzzles. The genetic code holds new allure - its four-letter sequence may have been documented but it contains deeper hidden ciphers, and geneticists relish the task of breaking them.
There remains a nagging concern, however, that some of these challenges will frustrate the hopes of earlier generations that the study of biology could reduce complex problems to a mechanistic understanding of the relationship between DNA and living things.
The Next Wave Of The Web, Nature News
Excerpts: The biggest theme is certainly (...) "the device formerly known as the mobile phone". The imminence of wireless broadband for mobiles means we are about to enter the phase of mobile and ubiquitous computing. It is also going to bring the Internet to the hundreds of millions of people who have no Internet access. We are talking now about creating mobile phones - devices - for $15 dollars apiece. (...)
Companies like Amazon are now using automated software to farm out paying computing tasks. The Web allows you to build a social workforce.
Software To Look For Experts Among Your Friends, NY Times
Excerpts: Tacit Software is preparing to introduce an online service that will make it simple to pick the brains of friends and colleagues for opinions and expertise.
Tacit plans to start testing the service, called Illumio, next month. The service allows the user to mine the data on the computers of friends, business associates and others with shared interests on any subjects.
However, Illumio is not a search engine, like Google or Yahoo. The system works by transparently distributing a request for information on questions like "Who knows John Smith?" and "Are Nikon digital cameras better than Olympus?" to the computers in a network of users.
New Analysis Of Networks Reveals Surprise Patterns In Politics, The Web, ScienceDaily
Excerpts: A new computer analysis technique developed at the University of Michigan that separates networks into communities yielded some surprises when used on real-world networks like political books, blogs, and metabolic systems. For instance, researchers used the algorithm to sort books sold on Amazon.com into left- and right-wing groups, and they found the book most appealing to conservatives was actually written by Democrat Zell Miller. (...) A network is a system of nodes connected by links and the nodes sometimes divide into groups or communities, said (...). By analyzing these groups, scientists better understand the structure and function of the network. (...)
Nature Offers Guidance On Organising Dynamic Networks, ScienceDaily
Excerpts: Today, for many, computer networks are an indispensable infrastructure that interconnects people, places and organisations. But increasingly they are beginning to creak as their complexity grows. Biological systems through years of evolution can offer clues on how to cope, as a research project has demonstrated. (...) The problem is caused by complex systems, where a large number a simple elements interact. And networking can be complex. Millions of interconnected nodes create inherent complexity and a growing sophistication of interactions between devices means complexity exists even when the number of devices is modest. (...)
Talking Nets: A Multi-Agent Connectionist Approach to Communication and Trust between Individuals, Cogprints
Excerpt: A multi-agent connectionist model is proposed that consists of a collection of individual recurrent networks that communicate with each other, and as such is a network of networks. The individual recurrent networks simulate the process of information uptake, integration and memorization within individual agents, while the communication of beliefs and opinions between agents is propagated along connections between the individual networks. A crucial aspect in belief updating based on information from other agents is the trust in the information provided. (...)
Mapping the Bid Behavior of Conference Referees, arXiv
Excerpt: The peer-review process, in its present form, has been repeatedly criticized. Of the many critiques ranging from publication delays to referee bias, this paper will focus specifically on the issue of how submitted manuscripts are distributed to qualified referees. Unqualified referees, without the proper knowledge of a manuscript's domain, may reject a perfectly valid study or potentially more damaging, unknowingly accept a faulty or fraudulent result. In this paper, referee competence is analyzed with respect to referee bid data collected from the 2005 Joint Conference on Digital Libraries (JCDL).(...)
Social Sciences: A New World Of Differences, Nature
Excerpts: For richer, for poorer ¡X the countries of the Americas and those of the Caribbean present stark contrasts in fortune. An explanation of those contrasts invokes branching chains of cause and effect.
Both the countries of North America (the United States and Canada) are twice as rich as the next richest New World country (Barbados), and some 20 times richer than the poorest (Haiti). The actual numbers are US$37,562, $30,677, $15,720 and $1,742, respectively1, expressed here as annual per capita gross domestic product (GDP) corrected for differences in purchasing power. Why are these differences so vast, and can an understanding of the causes help the plight of the poor New World countries? The answers are much debated by social scientists and policy-makers.
A Simple Rule For The Evolution Of Cooperation On Graphs And Social Networks, Nature
Excerpts: It is well known that in unstructured populations, natural selection favours defectors over cooperators. (...) Here we describe a surprisingly simple rule that is a good approximation for all graphs that we have analysed, (...): natural selection favours cooperation, if the benefit of the altruistic act, b, divided by the cost, c, exceeds the average number of neighbours, k, which means b/c > k. In this case, cooperation can evolve as a consequence of 'social viscosity' even in the absence of reputation effects or strategic complexity.
Resource Competition And Social Conflict In Experimental Populations Of Yeast, Nature
Excerpts: Understanding the conditions that promote the maintenance of cooperation is a classic problem in evolutionary biology1, 2, 3, 4, 5. The essence of this dilemma is captured by the 'tragedy of the commons'6: how can a group of individuals that exploit resources in a cooperative manner resist invasion by 'cheaters' who selfishly use common resources to maximize their individual reproduction at the expense of the group7, 8? Here, we investigate this conflict through experimental competitions between isogenic cheater and cooperator strains of yeast with alternative pathways of glucose metabolism9, and by using mathematical models of microbial biochemistry10.
Stem Cells: Good, Bad And Reformable, Nature
Excerpts: The ability of stem cells to continuously supply vast numbers of cells is magnificent, but it can be devastating if it runs amok, as in some tumours. So what makes a normal stem cell turn bad, and can it be redeemed?
The stem cell is a bit like the griffin of mythology ¡X half lion, half eagle; grand and powerful, but potentially monstrous in effect. These essentially unspecialized cells can renew their own population while supplying cells that mature (differentiate) into the specialized cells necessary for all tissues. Although this ability to reproduce and self-renew is sublime when functioning properly, its disorder creates masses of dysfunctional replicating cells.
Heart May Be Home To Its Own Stem Cells, New Scientist
A team of US researchers has discovered the ¡§home¡¨ of stem cells in the heart, lending credence to the idea that the heart has the capacity to repair itself. The finding raises the possibility that these cardiac stem cells could one day be manipulated to rebuild tissues damaged by heart disease - still the leading cause of death in the US and UK.
The stem cells were discovered clustered together with more mature heart cells in niches between cardiac muscle cells
Because fully developed heart cells do not divide, experts have believed the organ was unable to regenerate after injury. But, in 2003, researchers at Piero Anversa's laboratory at New York Medical College in Valhalla, New York, US, discovered stem cells in the hearts of mice, and subsequently humans.
OHSU Primate Center Research Suggests Multiple 'Body Clocks', Innovations-report
Excerpts: Research (...) suggests that contrary to popular belief, the body has more than one "body clock." The previously known master body clock resides in a part of the brain called the suprachiasmatic nucleus (SCN). (...) revealed the existence of a secondary clock-like mechanism (...). "Our latest research suggests that a separate but likely related clock resides in the adrenal gland. The adrenal gland is involved in several important body functions, such as body temperature regulation, metabolism, mood, stress response and reproduction. The research also suggests that other peripheral clocks reside throughout the body and that these clocks are perhaps interconnected."
Genetics: What Is A Gene?, Nature
Excerpts: The idea of genes as beads on a DNA string is fast fading. Protein-coding sequences have no clear beginning or end and RNA is a key part of the information package, reports Helen Pearson.
'Gene' is not a typical four-letter word. It is not offensive. It is never bleeped out of TV shows. And where the meaning of most four-letter words is all too clear, that of gene is not. The more expert scientists become in molecular genetics, the less easy it is to be sure about what, if anything, a gene actually is.
Genetics: Paramutable Possibilities, Nature
Excerpts: A curious genetic phenomenon allows certain genetic instructions to be passed between generations without the gene variants involved being transmitted. Some spotty mice provide clues to how this might happen.
One of the benefits of sex is that our parents give us two copies of nearly all our genes. So if one copy, or allele, doesn't work, there is a good chance that the other, operating independently, will be sufficient. Exceptions exist, but even in those cases the two alleles usually function independently. In rare cases, however, the alleles interact intimately, even though they reside on separate chromosomes, and whether one allele is expressed depends on directions given by the
Collective Evolution and the Genetic Code, arXiv
Abstract: A dynamical theory for the evolution of the genetic code is presented, which accounts for its universality and optimality. The central concept is that a variety of collective, but non-Darwinian, mechanisms likely to be present in early communal life generically lead to refinement and selection of innovation-sharing protocols, such as the genetic code. Our proposal is illustrated using a simplified computer model, and placed within the context of a sequence of transitions that early life may have made, prior to the emergence of vertical descent.
The New Era in Cancer Research, Science
Excerpts: For many years, discoveries about the genetic determinants of cancer appeared to be having only minor effects on efforts to control the disease in the clinic. Following advances made over the past decade, however, a description of cancer in molecular terms seems increasingly likely to improve the ways in which human cancers are detected, classified, monitored, and (especially) treated. Achieving the medical promise of this new era in cancer research will require a deeper understanding of the biology of cancer and imaginative application of new knowledge in the clinic, as well as political, social, and cultural changes.
Autophagy: Is It Cancer's Friend or Foe?, Science
Excerpts: Cells rely on autophagy to recycle their components, and much evidence favors the idea that this "self-eating" suppresses tumor development. But other data suggest that autophagy fosters tumor development and actually protects cancer cells from treatments (...)
(...) autophagy appears to suppress tumor development in animals. This includes demonstrations that some tumor-suppressor genes stimulate autophagy and that certain cancer-causing oncogenes inhibit it. But although such work suggests that boosting autophagy will prevent or treat cancers, "the situation is not so clear," cautions Patrice Codogno of the University of Paris-Sud in France.
Energy Deregulation: Licensing Tumors to Grow, Science
Excerpts: Taking their cue from a controversial, 80-year-old theory of cancer, scientists are reexamining how tumors fuel their own growth and finding new ways to cut off their energy supply (...)
The revival in cancer bioenergetics began in the mid-1990s when radiologists showed that positron emission tomography (PET) imaging could detect and map many tumors. In PET, an injected glucose analog highlights tumors, which are hungrier for glucose than normal cells are. "PET imaging," says Schreiber, "suggests that the glycolytic switch even precedes the angiogenic switch": the point at which tumors begin making their own blood vessels.
Immunology: Adaptable Innate Killers, Nature
Excerpts: Natural killer cells are versatile white blood cells that act in the innate immune system. Quite how adaptable they can be in the absence of other, more specialized, immune cells comes as a surprise.
Contact dermatitis is an occupational hazard for many people. This disruptive immune reaction can be caused by contact with an odd assortment of items, including plants, drugs, chemicals and even money1. In each case, small, reactive molecules from the item penetrate the skin and modify proteins within the tissue. Thus altered, the skin proteins are seen as foreign by the immune system, which then endeavours to destroy them.
How Ancient Whales Lost Their Legs, Got Sleek And Conquered The Oceans, Innovations-report
Excerpts: When ancient whales finally parted company with the last remnants of their legs about 35 million years ago, a relatively sudden genetic event may have crowned an eons-long shrinking process. An international group (...) used developmental data from contemporary spotted dolphins and fossils of ancient whales to try to pinpoint the genetic changes that could have caused whales, dolphins and porpoises to lose their hind limbs. More than 50 million years ago the ancestors of whales and dolphins were four-footed land animals, not unlike large dogs. They became the sleek swimmers we recognize today during the next 15 million years, (...).
Quantum-Like Brain: "Interference Of Minds", Biosystems
Excerpts: We present a contextualist statistical realistic model for quantum-like representations in physics, cognitive science, and psychology. We apply this model to describe cognitive experiments to check quantum-like structures of mental processes. The crucial role is played by interference of probabilities for mental observables. Recently one such experiment based on recognition of images was performed. This experiment confirmed our prediction on the quantum-like behavior of mind. (...) We propose a model of brain functioning as a QL-computer (there is a discussion on the difference between quantum and QL computers).

Scientists Shed New Light On Invisibility, Boston Globe
Excerpts: Inspiring the new research is a type of material known as ``metamaterial." Metamaterials have special properties because they are built with internal structures small enough to interact with light or other radiation. This allows scientists to build devices that can do things, such as bending light, in ways no naturally occurring substance can. (...)
Light from behind the sphere would flow through it, bend around the hollow in the center, and then continue out the front. No light could reach the hollow or escape from it.
Editor's Note: While this passive method requires new types of materials, there are of course already active methods in use, involving cameras on the back and flexible screens on the front.
Controlling Electromagnetic Fields, Science
Excerpts: Using the freedom of design that metamaterials provide, we show how electromagnetic fields can be redirected at will and propose a design strategy. The conserved fields--electric displacement field D, magnetic induction field B, and Poynting vector S--are all displaced in a consistent manner. A simple illustration is given of the cloaking of a proscribed volume of space to exclude completely all electromagnetic fields. Our work has relevance to exotic lens design and to the cloaking of objects from electromagnetic fields.
Optical Conformal Mapping, Science
Excerpts: An invisibility device should guide light around an object as if nothing were there, regardless of where the light comes from. Ideal invisibility devices are impossible due to the wave nature of light. This paper develops a general recipe for the design of media that create perfect invisibility within the accuracy of geometrical optics. The imperfections of invisibility can be made arbitrarily small to hide objects that are much larger than the wavelength. Using modern metamaterials, practical demonstrations of such devices may be possible. The method developed here can be also applied to escape detection by other electromagnetic waves or sound.
Definition, D-E-F-I-N-I-T-I-O-N, Definition, NY Times
Excerpts: Can we change the spelling bee to make it more useful for teaching real-world skills to some of the nation's brightest students? (...)
But in a world of word processing programs, correct spelling becomes secondary to other, more complex linguistic skills. If education is really what we are after, can we change the bee to make it more useful for teaching real-world skills to some of the nation's brightest students?
A Quick Fix For The Gas Addicts, NY Times
Excerpts: (...) G.M. announced its "fuel price protection program" on May 23. If you live in Florida or California and buy certain G.M. vehicles by July 5, the company will guarantee you gasoline at a cap price of $1.99 a gallon for one year ¡X with no limit on mileage. Guzzle away.
As The Associated Press explained the program, each month for one year, G.M. will give customers who buy these cars "a credit on a prepaid card based on their estimated fuel usage. Fuel usage will be calculated by the miles they drive, as recorded by OnStar, and the vehicle's fuel economy rating. (...)
Excerpts: GM is a leader in finding ways to make the most of every gallon of gas.
Now, in a time when the cost of gas has increased, we're helping drivers save money every time they fill up with the GM Fuel Price Protection program.
Complex Challenges: Global Terrorist Network
Warlords or Counter-Terrorists: U.S. Intervention in Somalia, Global Terrorism Analysis
Excerpts: As the insurgencies in Afghanistan and Iraq continue to dominate headlines, a new front in the war on terrorism has opened in Somalia. At a brutal cost to Mogadishu's civilian population, once-discredited warlords have reinvented themselves as "counter-terrorists," seeking and apparently gaining U.S. support by characterizing their Islamist opponents as agents of al-Qaeda. The warlords have grouped together as the Anti-Terrorism Alliance (ATA) and insist they are dedicated to expelling foreign al-Qaeda members they allege are sheltered by the Islamic Court Union (ICU).
US Slashes Hub Grants For Security - Antiterrorism Funds Cut By Nearly A Third, Boston Globe
Excerpts: The two cities that were attacked by terrorists on Sept. 11, 2001 -- New York and Washington, D.C. -- lost about 40 percent of their funding. At the same time, several smaller cities, including Louisville, Ky., and Omaha, saw their funds rise.(...)
(...) the department used a new system for evaluating applications for grant money. The formula employed a more sophisticated analysis of the risk posed by a potential terrorist attack, as well as the quality of the proposed spending plans submitted by each applicant city.
