01. Economics: When a Commodity Is Not Exactly a Commodity , Science
Excerpts: The metabolism of our global economy relies on trillions of daily
transactions, many of which involve goods and services termed commodities. In
the idealized competitive markets of conventional economic theory, specific
commodities are homogeneous and their quality is easily assessed. Because all
pork bellies are alike, your choices among them can be based on price alone.
But market transactions are not always so straightforward. Researchers have
recently begun to explore the ways in which the process of exchange itself may
modify the exchangers--altering product quality in unanticipated ways.

01.01. Market Manipulation, or Just Business as Usual? , Knowledge at Wharton
Excerpts: The recent turmoil in the financial markets is scary because it was
triggered by something new and poorly understood -- the collapse of subprime
mortgages. But it's not surprising for moods to turn sour when the good times
end, Siegel notes. A few years ago, the trigger was the collapse of the
tech-stock boom. This time, it's the end of the easy-money era and housing
bubble. "Swings of sentiment," Siegel adds, "have happened forever."

01.02. Addressing Consumer Concerns About Climate Change , The McKinsey
Quarterly
Excerpts: In a global survey, consumers say that a corporation's performance in
addressing the problems of the environment and climate change affects not only
how much they trust the company but also whether they would buy its products.
Consumers also want companies to promote the public good by providing healthier
and safer products, retirement and health care benefits for its employees, and
much else besides. Their expectations vary by industry and geography.

02. Blind to Change, Even as It Stares Us in the Face , NY Times
Excerpts: Tomasz Walenta Good Eye In deciding what to focus on, we scan and
sweep until something sticks out and brings our bouncing cones to a halt, as
shown above. Visual attentiveness is born of limited resources. "The basic
problem is that far more information lands on your eyes than you can possibly
analyze and still end up with a reasonable sized brain", Dr. Wolfe said. Hence,
the brain has evolved mechanisms for combating data overload, allowing large
rivers of data to pass along optical and cortical corridors almost entirely
unassimilated, and peeling off selected data for a close, careful view. In
deciding what to focus on, the brain essentially shines a spotlight from place
to place, a rapid, sweeping search that takes in maybe 30 or 40 objects per
second,(...).

03. European Roots: Human Ancestors Go Back In Time In Spanish Cave , Science
News
Excerpts: CAVE SAVE. Researchers who retrieved this fossil jaw from a
Spanish cave conclude that human ancestors reached Western Europe more than 1
million years ago. EIA/Jordi Mestre Fossil finds in Spain have yielded the
earliest known skeletal evidence of human ancestors in Europe, according to a
new report. A fossil jaw and tooth from the same individual, found during
excavations of a cave (...), The investigators assign the new discoveries to
the species Homo antecessor. A decade ago, they identified 800,000-year-old
fossils from another Atapuerca site as H. antecessor. In the Spanish
scientists' view, H. antecessor was an evolutionary precursor of European
Neandertals and modern humans.

04. What's Cookin' - Science Is In The Kitchen, And The Results Are Good For
Our Taste Buds , Science News
Excerpts: Sphere Of Flavor. Calcium bonds with sodium alginate to form a
jelly shell around a spoonful of mojito. Darko Zagar The relationship
between scientists and chefs, or lack thereof, troubled the late physicist
Nicholas Kurti. At a presentation for the Royal Society of London in 1969 he
lamented, "I think it is a sad reflection on our civilization that while we can
and do measure the temperature in the atmosphere of Venus, we do not know what
goes on inside our souffl?s." (...) "What is important is in your mouth,"
(...). More important are structural changes that result from heating or
cooling to body temperature, the action of saliva (an adult secretes 0.5 to 1.5
liters per day), and the shearing between the palate and the tongue. "There's n
o
tongue like the human tongue," van Aken says.

04.01. Brain's 'Sixth Sense' For Calories Discovered , ScienceDaily
Excerpts: The brain can sense the calories in food, independent of the taste
mechanism, researchers have found in studies with mice. Their finding that the
brain's reward system is switched on by this "sixth sense" machinery could have
implications for understanding the causes of obesity. For example, the findings
suggest why high-fructose corn syrup, widely used as a sweetener in foods,
might contribute to obesity. (...) In their experiments, the researchers
genetically altered mice to make them "sweet-blind," lacking a key component of
taste receptor cells that enabled them to detect the sweet taste. (...)

05. Neuroscience: Strength In Numbers , Nature
Excerpts: To store information, the brain modulates synapses, which mediate
communication between neurons. A closer look hints that subcellular changes in
response to groups of synapses facilitate this process. (...) (...) when
clusters of synapses on a dendritic branch are stimulated simultaneously, under
conditions thought to mirror brain states during learning, repeated activation
leads to gradual changes in the response of the branch.

06. Freedom of Expression , Science
Excerpts: As in civil society, where there must necessarily be checks and
balances on freedom of expression, cells have evolved a range of mechanisms to
regulate the expression of their constituent genes. By far the best-understood
medium for gene regulation is the protein transcription factor. The broad set
of rules by which these regulators operate is outlined by Hobert (p. 1785).
However, new and unexpected gene regulatory systems have been discovered in the
past decade, perhaps the most important of which involve microRNAs (miRNAs).

06.01. Genetics Of Gene Expression And Its Effect On Disease , Nature
Excerpts: Common human diseases result from the interplay of many genes and
environmental factors. Therefore, a more integrative biology approach is needed
to unravel the complexity and causes of such diseases. To elucidate the
complexity of common human diseases such as obesity, we have analysed the
expression of 23,720 transcripts in large population-based blood and adipose
[fat, Ed.] tissue cohorts comprehensively assessed for various phenotypes,
including traits related to clinical obesity. In contrast to the blood
expression profiles, we observed a marked correlation between gene expression
in adipose tissue and obesity-related traits. (...)

06.02. MicroRNAs Make Big Impression in Disease After Disease , Science
Excerpts: (...) the protein produced by the oncogene myc, which is frequently
active in cancer cells, downregulates dozens of microRNAs. But that's far from
the whole story, for the microRNA-gene network is unimaginably complex.
Although some proteins made by oncogenes home in on microRNAs, as Mendell
describes, the reverse is also true, with other microRNAs controlling the
activity of oncogenes. "The result is a series of interactions that can have a
very potent effect" on cancer, says Mendell.

06.03. Gene Regulation in the Third Dimension , Science
Excerpts: Analysis of the spatial organization of chromosomes reveals complex
three-dimensional networks of chromosomal interactions. These interactions
affect gene expression at multiple levels, including long-range control by
distant enhancers and repressors, coordinated expression of genes, and
modification of epigenetic states. Major challenges now include deciphering the
mechanisms by which loci come together and understanding the functional
consequences of these often transient associations.

06.04. Complex Riboswitches , Science
Excerpts: Using simple biochemical tricks, metabolite-binding riboswitches take
on gene control functions that have long been thought to be the work of protein
factors. Although modern riboswitches might be the last holdouts of primitive
genetic elements, some are capable of sensory and regulatory feats that are
competitive with their protein counterparts. Riboswitches are found in mRNAs,
where they bind small molecules and control gene expression. Most carry a
single binding site, or aptamer, that recognizes a target ligand.

07. Bugs Provoke The Immune System Into Fighting Cancer , New Scientitst
Excerpts: Disease-causing bugs could play a valuable role in the treatment of
cancer. Deliberately infecting people with the bacteria that cause listeriosis
could increase their ability to destroy tumours. The goal is to kick-start the
body's immune system by "provoking" it with the bacteria, which are modified to
trigger an attack on the cancer. US vaccine company Advaxis chose Listeria
monocytogenes because of its ability to stow away in immune cells called
antigen-presenting cells (APCs).

11. Pleiotropic Scaling Of Gene Effects And The 'Cost Of Complexity' , Nature
Excerpts: As perceived by Darwin, evolutionary adaptation by the processes of
mutation and selection is difficult to understand for complex features that are
the product of numerous traits acting in concert, for example the eye or the
apparatus of flight. Typically, mutations simultaneously affect multiple
phenotypic characters. This phenomenon is known as pleiotropy. (...) Some
authors have suggested that pleiotropy can impede evolutionary progress (a
so-called 'cost of complexity'). (...) This suggests that evolution of higher
organisms does not suffer a 'cost of complexity' because most mutations affect
few traits and the size of the effects does not decrease with pleiotropy.

oxygen and the heavy metal molybdenum in the ancient deep ocean may have
delayed the evolution of animal life on Earth for nearly 2 billion years. The
researchers arrived at their result by tracking molybdenum in black shales,
which are a kind of sedimentary rock (...). Molybdenum is a key micronutrient
for life and serves as a proxy for oceanic and atmospheric oxygen amounts.

Excerpts: Honeybees are unique in that they are the only social insects that
are known to recruit nest mates using the waggle dance. This waggle dance is
used by successful foragers to convey information about both the direction and
distance to food sources. Nest mates can use this spatial information,
increasing their chances of locating the food source. But how effective is the
bees' dance communication? Previous work has shown that dancing does not
benefit a honeybee colony under all foraging conditions and that the benefits
of dancing are small. We used an individual-based simulation model (...)

14.02. Behavioral Ecology: Smart Birds Lend a Beak for Food , Science
Excerpts: Scientists report this week that rooks, like chimpanzees, can
cooperate in food-getting tasks. (...) The researchers exposed eight pairings
of eight rooks to the challenge. In 60 trials per pair, all were able to pull
in the eggs and worms. But as with chimps, the pairs who were most
"tolerant"--that is, got along with each other the best as evidenced by
behaviors such as feeding from the same dish--picked up the trick the fastest.
The most tolerant pair reeled in the food platform in 63% of the tries, whereas
the least tolerant had a score of 20%,(...).

14.03. Rule Learning by Rats , Science
Excerpts: Rats can learn the rules governing simple sequences of stimuli and
then unexpectedly can generalize these rules to new situations. Using rules
extracted from experience to solve problems in novel situations involves
cognitions such as analogical reasoning and language learning and is considered
a keystone of humans' unique abilities. Nonprimates, it has been argued, lack
such rule transfer. We report that Rattus norvegicus can learn simple rules and
apply them to new situations. Rats learned that sequences of stimuli consistent
with a rule (such as XYX) were different from other sequences (such as XXY or
YXX).

News
Excerpts: READY FOR SPACE. Curled up into a 4 millimeter-long mummy, this
fly larva can suspend its life for years, withstanding severe drought and
extreme temperatures. D. Tanaka/National Institute of Agrobiological Sciences
in Japan The larvae of an African fly survive severe droughts by
essentially turning into candy drops, biologists have shown. The research might
lead to new ways of preserving blood for transfusions or even entire organs for
transplants. (...) Biologists have known for years that a sugar called
trehalose plays a crucial role in the survival tactics of several of these
species. During desiccation, trehalose replaces water in the cellular fluids
and is presumed to turn into a glassy state, much like melted sugar will
solidify into candy drops. The glassy sugar would keep cellular structures from
falling apart.

16. Evolution Of Learning In Fluctuating Environments , Evolution
Excerpt: Cumulative cultural change requires organisms that are capable of both
exploratory individual learning and faithful social learning. In our model, an
organism's phenotype is initially determined innately (by its genotypic value)
or by social learning (copying a phenotype from the parental generation), and
then may or may not be modified by individual learning (...). The environment
alternates periodically between two states, each defined as a certain range of
phenotypes that can survive. These states may overlap, in which case the same
phenotype can survive in both states, or they may not. We find that a joint
social and exploratory individual learning strategy (...).

Excerpts: (Image: Novamente) (...) synthetic pets like Novamente's dog
will be a far cry from today's virtual pets, such as Neopets and Nintendogs,
which can only perform pre-programmed moves, such as catching a disc. "The
problem with current virtual pets is they are rigidly programmed and lack
emotions, responsiveness, individual personality or the ability to learn," says
Ben Goertzel of Novamente. "They are pretty much all morons." In contrast,
Goertzel claims that synthetic characters like his dog can be taught almost
anything, even things that their programmers never imagined.

Excerpts: Most schoolchildren struggle to learn geometry, but they are still

be any different? A team of European researchers have developed an artificial
cognitive system that learns from experience and observation rather than
relying on predefined rules and models. (...) adopted an innovative approach to
making robots recognise, indentify and interact with objects, particularly in
random, unforeseen situations. Traditional robotics relies on having the robots
carry out complex calculations, such as measuring the geometry of an object and
its expected trajectory if moved. (...)

17. Chemistry: The Photon Trap , Nature
Excerpts: Chemists have long wanted to recreate photosynthesis in the lab - and
to improve on its efficiency at converting sunlight into fuel. (...) To start
the fuel-making process, sunlight hits a photo-active material. In plants this
is chlorophyll, but in the lab it can be a silicon semiconductor, which has its
electrons whacked out of position by the incoming photons. The dislodged
electrons start to flow in one direction, creating a current. Left behind are
positive charges, known as holes, and they drift in the opposite direction.
This is a basic solar cell, which requires silicon of high purity, otherwise
material defects cause the electrons and holes to recombine, reducing its
performance.

Excerpts: In the fable of the tortoise and the hare, the reptilian slowcoach
beats its fleet-footed rival in a race. A zinc catalyst recreates this story by
giving a less reactive chemical group a turn of speed over a rival group.(...)
Furthermore, in organic synthesis, it isn't always desirable to work with the
most reactive chemical groups first, so catalysts that allow reactions to occur
selectively at less reactive sites are highly desirable. Enzymes are the
acknowledged masters at reversing the reactivity of chemical groups in
molecules, but non-enzymatic catalysts may on occasion compete for the
accolade.

information.
(...) in carbon nanotubes, spin and orbital motion are more strongly coupled
than previously thought. Far from being a bad thing, this opens up new
possibilities for manipulating electron spin.

building blocks for tomorrow's nanocomputers - machines made of such tiny
elements that they are dominated not by forces that we're familiar with every
day, but by quantum properties. (...) "The unique structure of hypercubes,
including M-hypercubes, has been shown to be effective in parallel computing
and communication networks and provides a unique ideal intrinsic structure
which fulfills many of the needs of future nanocomputing systems," Lee said.
"These needs include massively parallel and distributed processing architecture

18.01. Quantum Effects Could Shed Light On Hazy Images , New Scientist
Excerpts: The special relationship between entangled photons of light could
help us gain a clearer picture of things like microscopic structures.
High-quality optical imaging involves measuring individual photons reflected
off an object. The trouble is that the photons can be deflected en route, and
extra photons created by thermal noise can obscure this weakened signal. Seth
Lloyd of Massachusetts Institute of Technology suggests that entangled photons
could sharpen up such images by providing a way to discard the noise. (...) The
imaging device could then ignore any unmatched photons.

Excerpts: But as Osama bin Laden slipped out of Tora Bora one foggy morning in
early December 2001, al-Qaeda left the realm of tactical intelligence and
became the complex organization-cum-movement which, six years later, we are
still struggling to understand. For a few years, the commanders of the
so-called War on Terror enjoyed the benefit of the doubt. After all, we did not
know what they knew. However, it has become increasingly clear how little was
known about al-Qaeda back in 2001, and how long it will take for us thoroughly
to understand the dynamics of global jihadism.

A short notice from Dean LeBaron
Dear ComDig Readers,
Our editor, Dr. Gottfried Mayer, is affectionately esteemed by many of you --
as readers, you know he devotes himself unselfishly to widening our knowledge
of complexity science. He was recently diagnosed with advanced colon cancer and
given a timetable of a very few years. Knowing Gottfried, you can imagine that,
in addition to the customary processes of chemotherapy, he would explore other
frontier therapies, especially those arising out of interdisciplinary
applications of complexity. These are expensive ... if he can find them.
Many of you have sent your good wishes and indicated your desire to assist.
With Gottfrieds permission, I am posting this note with information, below,
about how to send contributions to him. Please indicate the source since
Gottfried will want to express his warm gratitude.
I know that Gottfried, the good scientist that he is, will explain from time to
time what he is doing and what the results are ... and we will follow his
progress with great interest and hope.
