  2. Caves, Clusters, and Weak Ties: The Six Degrees World of Inventors, HBS Working Knowledge Next Article Bookmark and Share

    Excerpts:
    Your company's scientists and investors can be antennas that bring great ideas into your company. The key, says HBS professor Lee Fleming, is understanding small-world networks.(...)

    Agglomeration also happened here in Boston (the illustration shows the beginning of Boston's agglomeration in the mid-1990s), but it lagged, mainly because DEC (Digital Equipment Corporation) was falling apart. And so with the largest component failing, inventors and local universities like MIT could not coalesce around DEC, as they did out in Silicon Valley with IBM and Stanford.

    1. Disciplined Entrepreneurship, MIT Sloan Management Review Next Article Bookmark and Share

      Excerpts: Although the pursuit of opportunity promises outsized rewards to entrepreneurs and established enterprises, it also entails great uncertainty. The critical task of entrepreneurship lies in effectively managing the uncertainty inherent in trying something new. Some entrepreneurs foolishly try to ignore uncertainty; others go to the opposite extreme of attempting to avoid it altogether. Rather than ignore uncertainty or attempt to avoid it in the naive belief that every contingency can be anticipated, entrepreneurs should instead manage uncertainty by taking a disciplined approach.
    2. Are Animals As Irrational As Humans?, ScienceDaily Next Article Bookmark and Share

      Excerpts:
      The European starling, more rational than it seems. (Photo author: Cynthia Schuck Paim)
      Animals in the wild are constantly confronted with decisions where to nest, who to mate, where the best forage is. Mainstream models of choice in both economics and biology predict that preferences will be rational, or consistent across contexts, as a result of being motivated by self interest or, in the case of animals, reproductive success. Yet many studies report that when making decisions people often take shortcuts, using cognitive heuristics that may lead to economically irrational decisions, with similar claims now showing up in animal behavior studies. (...) question whether irrational decisions have been correctly demonstrated in animals. (...)
  3. The Dream Factory, Wired Next Article Bookmark and Share

    Excerpts: A fab lab is a miniature factory for the digital age. (...) Set it up, turn it on, and you can crank out not only solid objects like eyeglass frames and action figures but, thanks to Gershenfeld's research, electronic devices like radios and computers, too. The professor recently installed one at a technical institute in southwestern Ghana, where it has proven hugely popular. His success suggests that manufacturing - like publishing, coding, music and film distribution, and communications before it - is about to bust out of its industrial confines.
  4. The Role Of The State In Evolutionary Economics, Cambridge J. Econ. Next Article Bookmark and Share

    Excerpt: From an evolutionary perspective, the role of public policy extends far beyond the mere correction of market failures emphasised by neoclassical economics. Public policy may facilitate the market process. It may also guide the market process (in the case of multiple equilibria). The state can finally play a more creative role by allowing private agents to satisfy individually or collectively certain goals unattainable through market forces alone. However, this paper shows that although the scope of useful public policies is broader in an evolutionary approach than in neoclassical economics, the government's ability to direct the evolution of the economic system is highly limited. (...)
    1. Reported And Secret Interventions In The Foreign Exchange Markets, Finance Res. Lett. Next Article Bookmark and Share

      Except: Using a new approach relying on news wire reports, we estimate the proportion of secret interventions (i.e., unreported official interventions) in the foreign exchange markets that have been conducted by the three major central banks since 1985. We therefore revisit the estimation of conditional probabilities of secret operations (...). The proportion of secret interventions is found to be lower for concerted operations and to display a great deal of variability over time as well as across the three major central banks. Our analysis reveals that the Bank of Japan has recently adopted an intervention policy more based on secret operations.
    2. Good News About Poverty, NY Times Next Article Bookmark and Share

      Excerpts: Developing countries are seeing their economies expand by 6.1 percent this year - an unprecedented rate - and, even if you take China, India and Russia out of the equation, developing world growth is still around 5 percent. As even the cautious folks at the World Bank note, all developing regions are growing faster this decade than they did in the 1980's and 90's.

      This is having a wonderful effect on world poverty, because when regions grow, that growth is shared up and down the income ladder.

    3. Two-Factor Model of Income Distribution Dynamics, SFI Working Papers Next Article Bookmark and Share

      Abstract: This paper analyzes empirical income distributions and proposes a simple stochastic model to explain the stationary distribution and deviations from it. Using the individual tax returns data in the U.S. and Japan for 40 years, we first summarize the shape of income distribution by an exponential decay up to about the 90th percentile of income and a power decay for the top 1 percent. We then propose a minimal stochastic process of labor and asset income to reproduce the empirical characteristics. In particular, the Pareto exponent is derived analytically and matched with empirical statistics.
  5. Vast Borrowing Seen in Altering Social Security, NY Times Next Article Bookmark and Share

    Excerpts: The White House and Republicans in Congress are all but certain to embrace large-scale government borrowing to help finance President Bush's plan to create personal investment accounts in Social Security, (...). The White House says it has made no decisions about how to pay for establishing the accounts, (...). Many Democrats say that the costs associated with setting up personal accounts just make Social Security's financial problems worse, and that the United States can scarcely afford to add to its rapidly growing national debt.
    1. When Weakness Is a Strength, NY Times Next Article Bookmark and Share

      Excerpts: America's consumption binge has its mirror image in excess savings elsewhere in the world - especially in Asia and Europe. For now, America draws freely on this reservoir, absorbing about 80 percent of the world's surplus savings. Just as the United States has moved production and labor offshore in recent years, it is now outsourcing its savings.

      This is a dangerous arrangement. The day could come when foreign investors demand better terms for financing America's spending spree (and savings shortfall). That is the day the dollar will collapse, (...).

    Excerpts: For some people, writing a novel is a satisfying exercise in self-expression. For me, it's a hideous blend of psychoanalysis and cannibalism that is barely potent enough to overcome a series of towering avoidance mechanisms -- including my own computer. Writers and computers nowadays are locked in such an enduringly (...).

      Excerpts: "We're finding that my 4-year-old son knows how to use the videophone," he said. "Even his grandmother knows how to use the videophone, which is impressive. This is not just for early adopters, geeks and techno folks like myself."

      Convinced that almost anyone who can use a telephone can use his videophones, Mr. Martin said he planned to set up call centers in the coming weeks, including at hospitals where children can talk to (and see) hired "Santas at the North Pole."

    2. Hi, I'm Your Car. Don't Let Me Distract You., NY Times Next Article Bookmark and Share

      Excerpts: The study concluded that in most cases, drivers "overestimated the ease of use afforded by hands-free phone interfaces."

      Drivers can be easily distracted, even when they have both hands on the wheel. "In many cases, it's the amount of brain power you're using," said David Champion, the senior director of auto tests for Consumer Reports. "Even if you're using a hands-free phone, you're using quite a bit of brain power to actually have a discussion."

      (...), state laws are silent on other distracting technology inside a car.

    3. Transparent Transistor: See-Through Component For Flexible Displays, Science News Next Article Bookmark and Share

      Excerpts:
      Now You See It. Transparent transistors on a sheet of plastic can be seen only at certain angles. Such circuitry could find its way into computer displays in car windshields and other curved surfaces. Nature
      Imagine a car windshield that suddenly lights up to reveal a map of the city and directions to your next destination. Or picture a computer display that you can not only see through but also roll into a tube and slip into your coat pocket. Scientists in Japan have taken a major step to fulfilling such visions with the creation of a transparent transistor deposited on plastic. (...)

      (...) transparent circuitry could make existing displays brighter by increasing the amount of light reaching the viewer's eyes, (...).

  7. Concentration Hampers Simple Tasks, Nature News Next Article Bookmark and Share

    Excerpts: Why would increased frontal lobe activity make it harder to learn the pattern? (...) the frontal lobes are valuable in a crisis, when it is necessary to make a quick decision about which course of action to take. But this conscious processing might actually inhibit the automatic learning of simpler tasks, (...).

    So should we give our brains a break and stop trying to learn? It depends on the type of task, (...). For example, people who are learning to ski should try to relax as they go down the slope.

    1. Patterns: Pain and the Downsized Brain, New York Times Next Article Bookmark and Share

      Excerpts: People with chronic back pain showed measurable shrinkage of their brains when they were given M.R.I. scans, researchers reported yesterday.

      (...) the gray matter of the brain was 5 percent to 11 percent smaller than it was in other volunteers used for comparison. "The magnitude of this decrease is equivalent to the gray matter volume lost in 10 to 20 years of normal aging," they wrote.(...)

      "Chronic pain patients, and specifically chronic back pain patients, seem to have impairment in emotional decision making,"(...).

    A protein that normally plays a role in heart development shows early promise in mice for helping the heart heal after a heart attack.

    "This compound is one of the best leads for how one might reduce the size of heart attacks," (...). (...) works five times better than stem cells--the next best experimental option--at keeping heart cells alive. If the compound works as well in humans as in mice, Schneider says, eventually emergency personnel might give it to people who have just had a heart attack.

    1. Convincing Results: Stopping The Spread Of Cancer In The Body, Alphagalileo Next Article Bookmark and Share

      Excerpt: A team of Danish researchers have discovered that by blocking a specific enzyme, it is possible to check the spread of cancer in the body. This finding may be the first step towards preventing deaths due to cancer spreading to other parts of the body. The discovery may also help reduce the amount of chemotherapy used. (...) "What is special about the enzyme - urokinase plasminogen activator (uPA) - is that the cancer needs the enzyme in order to spread throughout the body, but the body does not need the enzyme to function normally. This means that we should be able to block the enzyme (...).
  9. Endurance Running Is In East Africans' Genes, New Scientist Next Article Bookmark and Share

    Excerpts: The long-distance running prowess of Ethiopia's elite male athletes is partly dictated by their genes.

    Researchers have established that such athletes are more likely to have certain variants of four Y chromosome genes compared with other Ethiopians. No one knows what the genes do, or how influential they are, but they are the first to be linked to east Africans' outstanding ability for endurance events.

    Ethiopian and Kenyan athletes have run 37 of the 40 fastest times recorded over 10,000 metres.

  10. A Two-Way Bioinformatic Street, Science Next Article Bookmark and Share

    Excerpts: The rapid emergence of Web-based bioinformatics systems reflects the research community's attempts to embrace the biological complexity uncovered by high-throughput genome, transcriptome, and proteome data acquisition and the sheer size of the modern scientific endeavor. If information systems can match this complexity, biology will be enriched as a result. If not, scientific excitement may paradoxically be dampened by data flow. The question is, how should biological information systems and the relationship between those who use them and contribute to them further evolve?

      Excerpts:
      Fascination with the Holy Grail has lasted for centuries, and now the Bletchley Park code-breakers have joined the hunt. But what is it that's made the grail the definition of something humans are always searching for but never actually finding?

      Could an obscure inscription on a 250-year-old monument (...) point the way to the Holy Grail - the jewelled chalice reportedly used by Jesus and his disciples at the Last Supper? (...)

Analysis of haploid yeast cells and their response to peptide mating pheromones has produced important advances in our understanding of (...) signaling mechanisms. Many of the components, their interrelationships, and their regulators were first identified in yeast. Current analysis of the pheromone response pathway (...) will benefit from new and powerful genomic, proteomic, and computational approaches that will likely reveal additional general principles that are applicable to more complex organisms.
    2. Jekyll and Hyde in the Microbial World, Science Next Article Bookmark and Share

      Excerpts: Fungi are nonmotile organisms that obtain carbon from compounds in their immediate surroundings. Confronted with nutrient limitation, the yeast Saccharomyces cerevisiae undergoes a dimorphic transition, switching from spherical cells to filaments of adherent, elongated cells that can invade the substratum. A complex web of sensing mechanisms and cooperation among signaling networks (including a mitogen-activated protein kinase cascade, cyclic adenosine monophosphate- dependent protein kinase, and 5?-adenosine monophosphate-activated protein kinase) elicits the appropriate changes in physiology, cell cycle progression, cell polarity, and gene expression to achieve this differentiation. Highly related signaling processes control filamentation and virulence of many human fungal pathogens.
    3. Emergence of Complex Dynamics in a Simple Model of Signaling Networks, arXiv Next Article Bookmark and Share

      Abstract: A variety of physical, social and biological systems generate complex fluctuations with correlations across multiple time scales. In physiologic systems, these long-range correlations are altered with disease and aging. Such correlated fluctuations in living systems have been attributed to the interaction of multiple control systems; however, the mechanisms underlying this behavior remain unknown. Here, we show that a number of distinct classes of dynamical behaviors, including correlated fluctuations characterized by 1/f-scaling of their power spectra, can emerge in networks of simple signaling units. We find that under general conditions, complex dynamics can be generated by systems fulfilling two requirements: i) a ``small-world'' topology and ii) the presence of noise. Our findings support two notable conclusions: first, complex physiologic-like signals can be modeled with a minimal set of components; and second, systems fulfilling conditions (i) and (ii) are robust to some degree of degradation, i.e., they will still be able to generate 1/f-dynamics.
  12. Stable and Unstable Attractors in Boolean Networks, arXiv Next Article Bookmark and Share

    Abstract: Boolean networks at the critical point have been a matter of debate for many years as, e.g., scaling of number of attractor with system size. Recently it was found that this number scales superpolynomially with system size, contrary to a common earlier expectation of sublinear scaling. We here point to the fact that these results are obtained using deterministic parallel update, where a large fraction of attractors in fact are an artifact of the updating scheme. This limits the significance of these results for biological systems where noise is omnipresent. We here take a fresh look at attractors in Boolean networks with the original motivation of simplified models for biological systems in mind. We test stability of attractors w.r.t. infinitesimal deviations from synchronous update and find that most attractors found under parallel update are artifacts arising from the synchronous clocking mode. The remaining fraction of attractors are stable against fluctuating response delays. For this subset of stable attractors we observe sublinear scaling of the number of attractors with system size.
  13. Magnetic Field Benefits Bacteria, Nature News Next Article Bookmark and Share

    Excerpts: The bacterium contains a pair of chlorophyll molecules, which allow it to harvest energy from light. But the process relies on a cascade of chemical reactions that can also turn oxygen from the air into a highly reactive form called singlet oxygen, which can damage DNA or proteins in a cell. A magnetic field slightly changes this sequence of reactions (...).

    (...) a magnetic field of 20 millitesla, just 400 times the Earth's magnetic field, was enough to cut singlet oxygen production by up to 50%.

      The pigeons chose correctly between 55% and 65% of the time in 24 tries.

      Previously, researchers had found magnetite crystals in the upper beaks of pigeons. To determine whether this region is the seat of the birds' magnetic sense, Mora attached tiny magnets to each pigeon's beak to impair its field detection ability. The birds' test accuracy plunged below 50%, then improved as they acclimated to the disturbance. Attaching nonmagnetic brass to their beaks did not impair their accuracy, however, nor did snipping the olfactory nerve leading from this area.

      Excerpts:
      Twilight Zone. In dim light, the helmet gecko can tell blue from gray, even when people can't. Inset: Pupil nearly closed in bright light (left) and wide open in dim light (right). Roth
      Of all the vertebrates, a gecko has just become the first to ace behavioral tests for seeing color in very low illumination.

      People, for example, go color-blind in light equivalent to dim moonlight, but helmet geckos, Tarentola chazaliae, don't. They can still tell a blue from a gray of the same intensity (...).

      In low light, Roth couldn't distinguish the cards, but the geckos snapped at crickets associated with blue cards more than twice as often as at those tagged with gray ones.

    Book Announcement: The quality of ecosystems is affected by the actions of different stakeholders who use them in a variety of ways. In order to understand this complex relationship between humans and nature, it is vital to understand the complexity of the interacting agents. The authors in this book attempt to do this by applying multi-agent systems to the problems of ecosystem management. The multi-agent approach to ecosystem management is a relatively new and rapidly developing field which takes a formal computational approach towards the interaction of humans with their environment. The authors highlight some of the promising new methodologies (...).

      Excerpts:
      The human hunting theory has been left out in the cold
      New evidence casts doubt on the theory that sabre-toothed cats, mammoths and other big North American mammals were driven to extinction by human hunting.

      Genetic analysis of bison remains shows their populations started to crash around 37,000 years ago - long before humans arrived in the New World.

      Researchers claim that climate change and other factors are more likely culprits in the extinction. (...)

  15. Balancing Food And Predator Pressure Induces Chronic Stress In Songbirds, Proc. Biol. Sc. Next Article Bookmark and Share

    Excerpts: The never-ending tension between finding food and avoiding predators may be the most universal natural stressor wild animals experience. The 'chronic stress' hypothesis predicts: (i) an animal's stress profile will be a simultaneous function of food and predator pressures given the aforesaid tension; and (ii) these inseparable effects on physiology will produce inseparable effects on demography because of the resulting adverse health effects. (...). We conducted a 2 × 2, manipulative food addition plus natural predator reduction experiment on song sparrows (Melospiza melodia) that was, to our knowledge, the first to demonstrate comparable synergistic effects in a bird (...).

      Excerpts: Techniques recently developed for the analysis of human social networks are applied to the social network of bottlenose dolphins living in Doubtful Sound, New Zealand. We identify communities and subcommunities within the dolphin population and present evidence that sex- and age-related homophily play a role in the formation of clusters of preferred companionship. We also identify brokers who act as links between sub-communities and who appear to be crucial to the social cohesion of the population as a whole. The network is found to be similar to human social networks in some respects but different in some others, (...).
