Cultural Reflections, Nature
Expert: The confucian tradition of respecting customs and hierarchy has cast a long shadow over modern China. Authoritarian rule and political conformity in the past decades have hampered the creation of an environment that fosters individual creativity. Deference to authority and to existing paradigms is a major barrier to scientific breakthrough.
Science education in China is extensive and rigorous, (...). But it takes more than this to cultivate scientists; students should be inspired to pursue knowledge itself, and a habit of raising questions needs to be fostered.
Making An Impact, Nature
Expert: Currently, only a small number of universities have adopted teaching methods similar to those in the United States and Britain, where students are encouraged to think critically and creatively. The majority of the universities and graduate schools in China place more emphasis on memorizing and accepting facts than on thinking innovatively and asking questions. (...)
The system for evaluating research proposals and distribution of funds in China also needs substantial improvement. (...)
There is a popular saying: "Small grants, big review; medium grants, small review; big grants, no review."

Abstract: For many years, research and management thinking has focused on understanding business relationships and networks. Now, the focus is shifting to managing business relationships and networks. This new approach focus poses two questions. Since networks are loosely coupled systems, to what extent are business networks manageable? Furthermore, how can a firm's ability to manage a network be characterized and measured? This paper addresses these two questions by synthesizing the current state of knowledge on management issues in networks and the contribution to managerial abilities in complex relationships. The discussion leads to a set of propositions describing the abilities firms will need to successfully manage complex business networks.

Altruism May Arise from Individual Selection, arXiv
Abstract: The fact that humans cooperate with non-kin in large groups, or with people they will never meet again, is a long-standing evolutionary puzzle with profound implications. Cooperation is linked to altruism, the capacity to perform costly acts that confer benefits on others. Theoretical approaches had so far disregarded costly acts that do not yield future benefits for the altruist, either directly or indirectly. Recently, strong reciprocity, i.e., the predisposition to cooperate with others and to punish non-cooperators at personal cost, has been proposed as a schema for understanding altruism in humans. While behavioral experiments support the existence of strong reciprocity, its evolutionary origins remain unclear: group and cultural selection are generally invoked to compensate for the negative effects that reciprocity is assumed to have on individuals. Here we show, by means of an agent-based model inspired on the Ultimatum Game, that selection acting on individuals capable of other-regarding behavior can give rise to strong reciprocity. The results, consistent with the existence of neural correlates of fairness, are in good agreement with observations on humans and monkeys.
Three (Marginal?) Questions Regarding Convergence, J. Econ. Studies
Abstract: This paper focuses on three (marginal?) questions (...). Given that the geographical units of analysis are usually quite different in economic size, is the weighting of economic units relevant in convergence analysis? The average per capita income of a given region, or country, is the first moment in the distribution of income, but what about the second moment, inequality, have we converged in inequality? (...) does the adjustment for inequality make important differences in the evolution of average per capita income? The answer to the first two questions is yes, but to the third it is clearly no.
Abstract: This paper is an attempt to understand how Amartya Sen's thinking on development and freedom has evolved from his critique of welfare economics and his concern with underdevelopment and poverty. Sen's contribution to the human development approach with its emphasis on positive freedom has also helped to provide a valuable counterweight to the dominant free market approach. However, some concerns are expressed that the approach does not give sufficient attention to long-run dynamics and that the conception of capability employed is not helpful for the understanding of development

Ancient Indians Made 'Rock Music', BBC News
Expert: The boulders which have small, groove-like impressions are called "musical stones" by locals. When struck with small granite rocks, these impressions emit deep, "gong-like notes".
These boulders may have been an important part of formalised rituals by the people who came there.
In some cultures, percussion plays a role in rituals that are intended for shamen to communicate with the supernatural world. The Antiquity work's author, Dr Nicole Boivin, of the University of Cambridge, UK, thinks this could be the purpose of the Kupgal stones.
Edge Vulnerability in Neural and Metabolic Networks, arXiv
Abstract: Biological networks, such as cellular metabolic pathways or networks of corticocortical connections in the brain, are intricately organized, yet remarkably robust toward structural damage. Whereas many studies have investigated specific aspects of robustness, such as molecular mechanisms of repair, this article focuses more generally on how local structural features in networks may give rise to their global stability. In many networks the failure of single connections may be more likely than the extinction of entire nodes, yet no analysis of edge importance (edge vulnerability) has been provided so far for biological networks. We tested several measures for identifying vulnerable edges and compared their prediction performance in biological and artificial networks. Among the tested measures, edge frequency in all shortest paths of a network yielded a particularly high correlation with vulnerability, and identified inter-cluster connections in biological but not in random and scale-free benchmark networks. We discuss different local and global network patterns and the edge vulnerability resulting from them.
Wireless Internet Stumbles Ahead, BBC News

The Consumers' Association conducted a survey last month and found that wireless computing is baffling a lot of consumers.
Controlling Synchronization in an Ensemble of Globally Coupled Oscillators, Physical Review Letters
Abstract: We propose a technique to control coherent collective oscillations in ensembles of globally coupled units (self-sustained oscillators or maps). We demonstrate numerically and theoretically that a time delayed feedback in the mean field can, depending on the parameters, enhance or suppress the self-synchronization in the population. We discuss possible applications of the technique.
Seeing the World in the Same Way, Science
Excerpt: As you watch Clint Eastwood in the 1966 movie classic The Good, the Bad, and the Ugly, what is happening in your brain? Is what happens in your brain the same as what happens in mine? Do we all see the world in the same way? This is the central question posed by Hasson et al. (1) in their brain imaging study reported on page 1634 of this issue.
Functional magnetic resonance imaging (fMRI) allows scientists to noninvasively investigate the organization of the human brain.
Intersubject Synchronization of Cortical Activity During Natural Vision, Science
Excerpts: To what extent do all brains work alike (...)? We explored this question by letting five subjects freely view half an hour of a popular movie while undergoing functional brain imaging. Applying an unbiased analysis in which spatiotemporal activity patterns in one brain were used to "model" activity in another brain, we found a striking level of voxel-by-voxel synchronization between individuals, not only in primary and secondary visual and auditory areas but also in association cortices. The results reveal a surprising tendency of individual brains to "tick collectively" during natural vision.
Hidden Neuronal Correlations in Cultured Networks, Physical Review Letters
Abstract: Utilization of a clustering algorithm on neuronal spatiotemporal correlation matrices recorded during a spontaneous activity of in vitro networks revealed the existence of hidden correlations: the sequence of synchronized bursting events (SBEs) is composed of statistically distinguishable subgroups each with its own distinct pattern of interneuron spatiotemporal correlations. These findings hint that each of the SBE subgroups can serve as a template for coding, storage, and retrieval of a specific information. c2004 The American Physical Society
Abstract: Epileptic seizures occur intermittently as a result of complex dynamical interactions among many regions of the brain. By applying signal processing techniques from the theory of nonlinear dynamics (...) we present evidence that epileptic seizures appear to serve as dynamical resetting mechanisms of the brain, that is the dynamically entrained brain areas before seizures disentrain faster and more frequently at epileptic seizures than any other periods. We expect these results to shed light into the mechanisms of epileptogenesis, seizure intervention and control, as well as into (...) spatiotemporal state transitions in other complex biological and physical systems.
Are You Slow In Coordinating Your Thoughts?, ScienceDaily
Excerpts: Many complex systems are composed of a large number of similar units that are connected in a complicated manner. An important example is provided by neural networks where nerve cells in the brain communicate by exchanging pulses via synaptic connections. (...) grow synaptic connections in a highly specific but irregular fashion. In such systems, a particular question is how rapid coordination, e.g. synchronization, between units of a complex network can be achieved. (...) theory of random matrices can also be applied to the dynamic evolution of complex networks.

Memories Are Harder To Forget Than Currently Thought, ScienceDaily
Excerpts: While it might not seem so the next time you go searching for your car keys, scientists at the University of Pennsylvania have shown that memories are not as fluid as current research suggests. Their findings challenge the prevailing notion on how memories are stored and remembered - or that a recalled memory could be altered (...). "We show that the act of retrieving an old memory and then putting it back into storage is a different process than creating a memory in the first place. Unfortunately, it could mean that 'erasing' traumatic memories is not as simple as one might hope."
Rapid Population Decline In Red Knots: Fitness Consequences, Alphagalileo & Proc. Biol. Sc.
Abstract: Red knots wintering in Tierra del Fuego undertake marathon 30,000 km hemispheric migrations annually. Like commercial aircraft, spring migrants stop and refuel at a few key sites along the route. At the last site in Delaware Bay birds forage on horseshoe crab eggs, doubling their body mass in about two weeks. Catches of banded birds showed that in 1997-2002 an increasing proportion of knots failed to reach optimal departure masses because of food shortage from over-harvesting of crabs and late arrival of many birds in the bay. Consequently, (...) population declined alarmingly from 53,000 to 27,000 in 2000-2002 (...).

No Moon, No Life On Earth, Suggests Theory, New Scientist
Excerpts: Without the Moon, there would have been no life on Earth.
Four billion years ago, when life began, the Moon orbited much closer to us than it does now, causing massive tides to ebb and flow every few hours. These tides caused dramatic fluctuations in salinity around coastlines which could have driven the evolution of early DNA-like biomolecules.
This hypothesis, which is the work of Richard Lathe, a molecular biologist at Pieta Research in Edinburgh, UK, also suggests that life could not have begun on Mars.
Mobile Elements: Drivers of Genome Evolution, Science News
Abstract: Mobile elements within genomes have driven genome evolution in diverse ways. Particularly in plants and mammals, retrotransposons have accumulated to constitute a large fraction of the genome and have shaped both genes and the entire genome. Although the host can often control their numbers, massive expansions of retrotransposons have been tolerated during evolution. Now mobile elements are becoming useful tools for learning more about genome evolution and gene function.

Planetary Science: Secrets Of The Deep, Nature
Excerpts: For Earth-like planets, convective motions are typically modelled in a thick rotating shell of electrically conducting fluid. (...)
But such models are largely unable to capture the complexities of the magnetic fields of Uranus and Neptune. The measurements made by Voyager 2 around these planets revealed that their fields are not predominantly dipolar (like a bar magnet), but also have a quadrupole component (as though produced by a combination of two bar magnets, with two north and two south poles).
Cause Of Uranus' And Neptune's Unusual Magnetic Fields, Nature
Excerpt: The discovery of Uranus' and Neptune's non-dipolar, non-axisymmetric magnetic fields destroyed the picture-established by Earth, Jupiter and Saturn-that planetary magnetic fields are dominated by axial dipoles. Although various explanations for these unusual fields have been proposed, the cause of such field morphologies remains unexplained. Planetary magnetic fields are generated by complex fluid motions in electrically conducting regions of the planets (a process known as dynamo action), and so are intimately linked to the structure and evolution of planetary interiors.
Hurricanes And Butterflies
Excerpt: Chaotic systems can be characterized by the swirling patterns of 'strange attractors'. A powerful method to determine their behaviour has been validated for the most famous case, the Lorenz attractor.
(...) developed a powerful new method to determine from experimental observation of a system whether it is chaotic, and, if it is, what the precise quantitative nature of that chaos is. Their method is based on fractal geometry. Fractals are structures or curves that remain rough or heterogeneous on all length scales and are characterized by their 'fractal dimension'.
British Butterflies Are Going, Going ..., Science Now
Expert: A comparison of changes in bird, butterfly, and plant populations (...) suggests that, contrary to current thinking, unglamorous species may be disappearing even more rapidly than other organisms.
For decades, biologists have struggled to determine humans' impact on the flora and fauna around them. Insects and other invertebrates are so plentiful and cryptic that it's been hard to get a handle on their numbers or calculate the toll. Thus these researchers have used birds and mammals to monitor biodiversity, without many data to suggest this was the right approach.
Quantum Information: Flight Of The Qubit, Nature
Excerpts: A trapped ion emits a photon. Ion and photon are entangled, so the photon carries away information on the state of the ion. Now realized, this system could become a communication link in a quantum network.
(...) It could also efficiently model processes that are excessively difficult to model using existing technology. (...) progress has been made in the past few years. It is now widely acknowledged that one of the most promising systems for quantum computation is an array of ions, trapped and controlled inside an electric field.
Characterizing Entanglement via Uncertainty Relations, Phys. Rev. Lett.
Expert: We derive a family of necessary separability criteria for finite-dimensional systems based on inequalities for variances of observables. We show that every pure bipartite entangled state violates some of these inequalities. Furthermore, a family of bound entangled states and true multipartite entangled states can be detected. The inequalities also allow us to distinguish between different classes of true tripartite entanglement for qubits. We formulate an equivalent criterion in terms of covariance matrices. This allows us to apply criteria known from the regime of continuous variables to finite-dimensional systems
Stem Cells: More Like A Man, Nature
Excerpts: Most female mammals experience a reproductive decline with increased age, previously attributed to the instability of ageing oocytes. But could it be due to a previously unrecognized stem-cell well drying up?
Why can't a woman be more like a man? Male mammals generally can reproduce throughout most of their adult lives by continuously generating sperm precursors from germline stem cells maintained within the testis. In contrast, most mammalian females show a reproductive decline as they get older. Females of the few species that remain fertile throughout life, (...).
Adult Mammals May Produce Eggs After All, Science
Excerpts: A baffling inconsistency in a Boston lab is threatening to overturn a dogma of reproductive biology: that female mammals produce no new eggs after birth. A series of studies on mice has prompted a flabbergasted team of biologists to conclude that mouse ovaries harbor a previously undiscovered type of stem cell that can form new eggs through adulthood. The finding has far-flung implications, touching on everything from fertility and aging to the childbearing capacities of young cancer patients.
cientists have found a way to grow a bountiful supply of disease-fighting cells that might one day boost therapy for cancer and HIV.
T cells swallow up infected or cancerous cells.
The cells, called T cells, normally patrol the body and swallow up infected or cancerous cells. But chemo- or radiotherapy, and the HIV virus, destroy them.
Now a Canadian team have grown potentially limitless T cells in the laboratory. "We're very excited," says immunologist Juan Carlos Zúñiga-Pflücker of the University of Toronto.

Experts Fear Terrorists Are Seeking Fuel-Air Bombs, New Scientist
Excerpts: Some experts fear that terrorists are trying to develop thermobaric and fuel-air bombs which can be even more devastating than conventional devices.(...)
The devices use a small charge to generate a cloud of explosive mixed with air. The main explosion is then detonated by a second charge (a fuel-air explosion), or by the explosive reacting spontaneously with air (a thermobaric explosion). The resulting shock wave is not as strong as a conventional blast, but it can do more damage as it is more sustained (...).
Defusing Fertiliser May Make Bomb-Building Harder, New Scientist
Excerpts: Millions of tonnes of ammonium nitrate are produced each year for use as a fertiliser. Mining companies turn small quantities into an explosive by mixing the chemical with fuel oil. While it is not necessarily easy for would-be bombers to do this with fertiliser-grade ammonium nitrate, it is not impossible.
Now Speciality Fertilizer Products, (...), is patenting a water-soluble polymer coating for the fertiliser granules that repels fuel oil. The coating dissolves rapidly in soil, so it would not interfere with ammonium nitrate's main function as fertiliser.
Abstract: Paul Krugman Op-Ed column scores Pres Bush for his reluctance to focus on terrorists who actually attacked America and their backers in Saudi Arabia and Pakistan; says Bush's reluctance to commit sufficient forces in Afghanistan allowed Osama bin Laden to escape and Al Qaeda to regroup; says focus on Iraq and Pres Saddam Hussein shifted precious resources from terrorism; says actual Bush record is one of indulgence toward regimes that are strongly implicated in terrorism and of focusing on threats only when forced to by events.
