01. The Cultural Wealth Of Nations , Nature

Excerpts: Why, when the human race shows comparatively little genetic
variation, are cultural
differences so widespread and enduring? Thinking about cultures in terms of
biological species
provides some provocative answers. (...)

Just as species carry genetic adaptations to their environments,we believe
that cultural
adaptations have evolved in response to social life, and that such
adaptations work to maintain
cultural identity and coherence.Like species that do not interbreed, human
cultures are
surprisingly resistant to influences from other cultures and often act as
barriers to gene flow.

01.01. Geneticists Study Chimp uman Divergence , Nature

Excerpts: Scientists combing the draft of the chimpanzee genome sequence
are finding tantalizing
hints about the differences between humans and our closest relatives. (...)

Researchers (...), for example, are working on genes that encode enzymes
called proteases. These
genes are almost identical in humans and chimps except for one subset,
found in the immune system,
that varies greatly between the two species. (...)
They could also explain why chimps are less severely affected than humans
by AIDS or Alzheimer's
disease, and might lead to treatments for such conditions.

01.02. RNA Finds A Simpler Way , Nature

Excerpts: Is there no end to the versatility of RNA? The latest feat to be
revealed is RNA's
ability to switch off genes through a neatly straightforward mechanism. So
it isn't only proteins
that can repress gene activity.

Organisms profit from synthesizing only those enzymes whose products are in
demand. (...) A
standard textbook mechanism by which this is achieved is repression. (...)
describe a bacterial
gene-regulation system with a twist. The repressor is not a protein, but
instead is a switchable

01.03. Parallel Evolution Is in the Genes , Science

Excerpts: The pages of any bird guide reveal a spectacular diversity of
colors and color patterns.
Although color patterns vary within species, often they also distinguish
closely related species.
Variations in color are thought to have evolved through the interplay of
sexual selection and
natural selection. What is less obvious--because the birds are on different
pages of the guide--is
the repeated appearance of similar color patterns among distantly related
species (parallel
evolution).

02. Agent-based Model Construction In Financial Economic System , arXiv

Abstract: The paper gives picture of enrichment to economic and financial
system analysis using
agent-based models as a form of advanced study for financial economic data
post-statistical-data
analysis and micro-simulation analysis. Theoretical exploration is carried
out by using comparisons
of some usual financial economy system models frequently and popularly used
in econophysics and
computational finance. Primitive model, which consists of agent
microsimulation with fundamentalist
strategy, chartist, and noise, was established with an expectation of
adjusting micro-simulation
analysis upon stock market in Indonesia. The result of simulation showing
how financial economy
data resulted analysis using statistical tools such as data distribution
and central limit theorem,

(Situngkir & Surya, 2003b). This
paper is ended with several further possible advancements from the model built.

03. EU Enlargement And Immigration , J. Common Market Studies

Abstract: This article assesses the consequences of EU enlargement for
east-west migration. It is
argued that expectations on future economic, social and political variables
are crucial for
immediate immigration. Specifically, if EU membership is refused, fear of
future restrictions on
immigration will lead to increased current migration. Moreover, EU
accession is likely to reduce
income gaps between the accession countries and the current Member States
reducing the incentives
to emigrate. We conclude that granting EU accession to eastern European
countries will not
necessarily induce massive east-west migration flows

04. Methane Poses Mars Life Puzzle , BBC News Online

Excerpts: Methane has been found in the Martian atmosphere, which
scientists say could be a sign of
present-day life on Mars.

It was detected by telescopes on Earth and has recently been confirmed by
instruments onboard the
European Space Agency's orbiting Mars Express craft.

Methane lives for a short time in the Martian atmosphere so it must be
being constantly
replenished.

There are two possible ways to do this. Either active volcanoes, but none
have yet been found on
Mars, or microbes.

05. Quantum Channel Capacities , Science

Summary: Virtually all of today's information technology is based on the
manipulation of classical
bits. Quantum systems offer the potential of a much more powerful computing
technology, however. In
their Perspective, Bennett and Shor discuss an important aspect of quantum
computing--the
theoretical capacity of a quantum information channel. Although a number of
concepts can be carried
over from classical information theory, quantum systems have their own
unusual properties.
Recently, researchers have been able to show that these unique quantum
aspects can provide much
higher information flow than previously expected.

Review Letters

Abstract: We prove that for every Bell's inequality, including those which
are not yet known, there
always exists a communication complexity problem, for which a protocol
assisted by states which
violate the inequality is more efficient than any classical protocol.
Violation of Bell's
inequalities is the necessary and sufficient condition for quantum protocol
to beat the classical
ones

05.02. Complexity is Elusive , Phys. Rev. Focus

Excerpt: The researchers found that for some rules, the low-res version
behaved simply and
predictably, even when the high-res version was computationally irreducible
and therefore
unpredictable. In other words, the complexity was only in the unimportant
details. Goldenfeld
concludes that if you only need approximate results, they are predictable
in many complex problems,
and "computational irreducibility is not the right way to measure complexity."
Wolfram says the "nice, small paper" is useful, if not very surprising. The
interesting issue, he
says, is "under what circumstances will large-scale rules emerge" that
allow a simple, predictable
description of a complex phenomenon.

06. Turning Points, From 'Not Wrong' To (Maybe Right) , Nature

Excerpts: When I tried to write up our work for publication, there was a
certain feeling of
unreality and embarrassment about the complexity and arbitrariness of what
we had come up
with.(...)
We put aside the ot wrong?complicated models with spontaneous supersymmetry
breaking,and wrote a
short paper that,taken literally (with unbroken supersymmetry), was wrong.
But it presented a
result that was so straightforward and successful that it made the idea of
putting gauge symmetry
and supersymmetry unification together seem (maybe) right.We put offthe
problem ofhow supersymmetry
gets broken.

Excerpts: Supporters of the president often point out that private funds

going on at biotech
firms. But the work is much impeded without the help of the federal
government. "Frankly, from a

07. Pentagon Attempts To Bend Light To Its Will , Nature

Excerpts: Negative refraction bends light in an unusual way.

Although some physicists were sceptical about the results (see Nature 420,
119?20; 2002),
subsequent experiments have led most to accept the finding, says John
Pendry, a physicist at
Imperial College in London who works on negatively refracting materials.
For example, George
Eleftheriades and Anthony Grbic, physicists at the University of Toronto,
have recently created a
microwave lens from a negatively refracting structure (G. Eleftheriades and
A. Grbic Phys. Rev.
Lett. in the press).


Browning says that such advances convince her that the effect is real. But
she still has questions
about how the materials work. For example, some predict that the structures
will amplify light
waves that are normally dissipated by glass optics. If true, the material
could make lenses that
are more powerful than any possible with conventional optics. "But we're
still unsure of the
physics," Browning adds.

Excerpts:


This diagram shows a benzene molecule configured as an XOR logic gate. Each
sphere represents an
atom. The red and dark blue spheres represent the molecule's side groups,
which can be rotated to
change the molecule's electrical conductance. The green shapes are electrodes.



The scheme could eventually be used to produce small, fast computers and to
store large amounts of
data in very small spaces. The method could also be modified to make
sensors for detecting
individual molecules.

The researchers' plan calls for connecting a pair of benzene molecules to
two gold electrodes. The
molecules contain nitrogen-oxygen side groups whose rotational positions
can represent the 1s and
0s of computer information.

09. Buckminsterfullerenes: A Non-Metal System For Nitrogen Fixation , Nature

Abstract: In all nitrogen-fixation processes known so far ?including the
industrial Haber osch
process, biological fixation by nitrogenase enzymes and previously
described homogeneous synthetic
systems ?the direct transformation of the stable, inert dinitrogen molecule
(N2) into ammonia
(NH3) relies on the powerful redox properties of metals. Here we show that
nitrogen fixation can
also be achieved by using a non-metallic buckminsterfullerene (C60)
molecule, in the form of a
water-soluble C60:-cyclodextrin (1:2) complex, and light under nitrogen at
atmospheric pressure.
This metal-free system efficiently fixes nitrogen under mild conditions by
making use of the redox
properties of the fullerene derivative.

Excerpts: First, it is the rare case today when an unmodified natural
product like taxol becomes a
drug. It is also inconceivable that a human with or without computational
tools could propose a
single chemical structure that ends up as a drug; there are far too many
hurdles and subtleties
along the way. Most drugs now arise through discovery programs that begin
with identification of a
biomolecular target of potential therapeutic value through biological
studies including, for
example, analysis of mice with gene knockouts.

Excerpts: Researchers have identified genes that control the way mosquitoes
respond to the malaria
parasite. Their discovery could aid the development of anti-malarial
strategies by using a
mosquito's own immune system to curb the disease.

The parasite that causes malaria, known as Plasmodium, usually goes
unnoticed by the mosquito in
which it grows. But if the insect was tweaked to detect and attack the
intruder, the mosquito would
destroy the parasite before it has a chance to spread to humans.

11. Rare Stem Cells Appear To Drive Cancers , Science News

Excerpts: Why are many brain tumors and other cancers so difficult to treat?

For decades, cancer researchers have wrestled with two competing visions of
tumors. In one
scenario, all the cells of a tumor are pretty much the same. That is, they
have an equal capacity
to divide and form new tumors.

In the other scenario, only a few select cells from a tumor have the
capacity to initiate new,
full-fledged tumors. These bad seeds are the cancer stem cells.

11.01. Cancer: Survival Pathways Meet Their End , Nature

Excerpts: Conventional chemotherapeutic approaches to treating tumours can
be hit-and-miss. One way
to ensure successful treatment may be to go for the jugular of cancer-cell
survival signalling as
well.

Chemotherapy uses powerful drugs designed to induce cancer cells to commit
suicide. So why don't
all tumours succumb to these drugs? The answer is that cancer cells have an
inbuilt urge to
survive, so any genetic change that favours survival amidst adverse
conditions will be selected
for. (...) targeting specific molecules will impart sensi-tivity to
chemotherapy ?a combinatorial
approach.

12. How And Why Brains Create Meaning From Sensory Information , Int. J.
Bifur. & Chaos

Abstract: Semantics is the essence of human communication. Information
technology is faced with the
problem of using intelligent machines as intermediaries for interpersonal
communication. The
problem (...) has been intractable because brains and machines work on very
different principles.
Machines process information that is fed to them. Brains construct
hypotheses and test them by
acting and sensing. Brains sample information, hold it briefly, construct
meaning, and then discard
the information. A solution (...) is to simulate how brains create meaning
and express it as
information by making a symbol to represent the meaning to another brain in
pairwise communication.

also the process he found at work in immunology: he showed that the body

Abstract: We discuss a notion of information processing in brain and

particular the processing of meaningful information, which is testable by
means of an experimental
coordination and transition paradigm. Two hypotheses on the existence and
persistence of mappings
between the dynamics of behavioral and brain signals are formulated. A
mathematical foundation for
the first hypothesis is suggested (...). Brain signals are captured as
cortical currents, as well
as the resulting scalp topographies, such as electroencephalograms (EEG)
and magnetoencephalograms
(MEG). Experimental evidence is provided to support the hypothesis on the
existence of such
spatiotemporal mappings between behavioral and brain signals.

Abstract: During reading, our eyes perform complicated sequences of

models of eye movement control suggest that this seemingly erratic behavior
can be attributed to
noise in the oculomotor system and random fluctuations in lexical
processing. Here, we present a
qualitative analysis of a recently published dynamical mode and propose
that deterministic
nonlinear control accounts for much of the observed complexity of eye
movement patterns during
reading. Based on a symbolic coding technique we analyze robust statistical
features of simulated
fixation sequences.

Excerpts: Geological and palaeomagnetic studies indicate that ice sheets
may have reached the
Equator at the end of the Proterozoic eon, 800 to 550 million years ago,
leading to the suggestion
of a fully ice-covered 'snowball Earth'. Climate model simulations indicate
that such a snowball
state for the Earth depends on anomalously low atmospheric carbon dioxide
concentrations, in
addition to the Sun being 6 per cent fainter than it is today. (...) This

changes could have triggered a progressive transition from a 'greenhouse'

Abstract: During the 1930s, the United States experienced one of the most
devastating droughts of
the past century. The drought affected almost two-thirds of the country and
parts of Mexico and
Canada and was infamous for the numerous dust storms that occurred in the
southern Great Plains. In
this study, we present model results that indicate that the drought was
caused by anomalous
tropical sea surface temperatures during that decade and that interactions
between the atmosphere
and the land surface increased its severity. We also contrast the 1930s
drought with other North
American droughts of the 20th century.

the shore, with concomitant beachfront development and exponentially
increasing total values for

development has unfortunately coincided with a century of accelerating

means that the prediction of the future rate of shoreline retreat has

results suggest that under
certain conditions supershear rupture propagation can be facilitated during
large earthquake
events.

Whether and how supershear rupture occurs during earthquakes has important
implications for seismic
hazards, because the rupture speed influences the character of near-field
ground motions.

To answer the above-stated questions, we conducted experiments that mimic
the earthquake rupture
processes.

Network , arXiv

Abstract: 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 subcommunities 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 such as the level of
assortative mixing by degree
within the population. This difference elucidates some of the means by
which the network formed and
evolves.

two foraging patches and
then tested the fish for a patch preference. The findings suggest that
sticklebacks flexibly adjust
their decision making to exploit the most reliable information available.
Fish preferentially based
their decisions on personal information when it was clear and consistent
(...), but switched to
copying others when their personal information was unclear or outdated.

15.02. Self-organization of Collaboration Networks , arXiv

Abstract: We study collaboration networks in terms of evolving,
self-organizing bipartite graph
models. We propose a model of a growing network, which combines
preferential edge attachment with
the bipartite structure, generic for collaboration networks. The model
depends exclusively on basic
properties of the network, such as the total number of collaborators and
acts of collaboration, the
mean size of collaborations, etc. The simplest model defined within this
framework already allows
us to describe many of the main topological characteristics (degree
distribution, clustering
coefficient, etc.) of one-mode projections of several real collaboration
networks, without
parameter fitting. We explain the observed dependence of the local
clustering on degree and the
degree--degree correlations in terms of the ``aging'' of collaborators and
their physical
impossibility to participate in an unlimited number of collaborations.

15.03. Networks, Fields, and Organizations: Micro-Dynamics, Scale and
Cohesive Embeddings , SFI
Working Papers

Abstract: Social action is situated in fields that are simultaneously
composed of interpersonal
ties and relations among organizations, which are both usefully
characterized as social networks.
We introduce a novel approach to distinguishing different network
macro-structures in terms of
cohesive subsets and their overlaps. We develop a vocabulary that relates
different forms of
network cohesion to field properties as opposed to organizational
constraints on ties and
structures. We illustrate differences in probabilistic attachment processes
in network evolution
that link on the one hand to organizational constraints versus field
properties and to cohesive
network topologies on the other. This allows us to identify a set of
important new micro-macro
linkages between local behavior in networks and global network properties.
The analytic strategy
thus puts in place a methodology for Predictive Social Cohesion theory to
be developed and tested
in the context of informal and formal organizations and organizational
fields. We also show how
organizations and fields combine at different scales of cohesive depth and
cohesive breadth.
Operational measures and results are illustrated for three organizational
examples, and analysis of
these cases suggests that different structures of cohesive subsets and
overlaps may be predictive
in organizational contexts and, similarly, for the larger fields in which
they are embedded, and
for predictions of feedback from the field context back to organizations.

16. Adaptations For Nothing In Particular , J. Theor. Social Behav.

Abstract: An element of the contemporary dispute amongst evolution minded
psychologists and social
scientists hinges on the conception of mind as being adapted as opposed to
adaptive. This dispute
is not trivial. The possibility that human minds are both adapted and
adaptive courtesy of
selection pressures that were social in nature is of particular (...). I
suggest that the notion of
an evolved psychological adaptation in social psychology can be retained
only if it is accepted
that this adaptation is for social interaction and has no rigidly fixed
function and cannot be
described in terms of algorithmic decision rules or fixed inferential
procedures.

16.01. What Happened To The "Social" In Social Psychology? , J. Theor.
Social Behav.

Abstract: This article describes the historical abandonment of the
distinctive conception of the
social dimensions of cognition, emotion and behavior embraced by American
social psychologists in
the early decades of the twentieth century. It is suggested that part of
the reason why the
original conception of the social was abandoned by American psychologists
was because of its
association with theories of the "group mind," (...). It is suggested that
while these factors
partly explain the neglect of the social in American social psychology,
none represent particularly
good reasons for abandoning the original conception of the social.

long before they finished serving their sentences. Sheriff Lee Baca says
budget cuts made him do it
-- otherwise, he'd have to take some patrolling deputies off the streets.

itself through mobile

 From 6pm the day before, until long into the evening, 5,000 people
gathered in the Spanish captial
to vent their anger at what they saw as a deliberate government cover-up
regarding the perpetrators
of the recent bombings.(...)
Most remarkable of all, the protests were organised in just a few hours,
via text message and
email, by a disillusioned electorate that had decided to take matters into
their own hands.

19.01. Europe, U.S. Diverge on How to Fight Terrorism , Washington Post

Excerpts: "Europe is not at war," (...). "We have to energetically oppose
terrorism, but we mustn't
change the way we live."

Between those two declarations lies a gap that reflects the different
modern histories, cultures
and approaches to terrorism of the United States and Europe, according to
politicians and analysts
on the continent. (...)
At a summit that ended Friday, EU leaders announced several measures
designed to increase
cooperation among their police forces and intelligence services. But the
attacks have not led to a
fundamental shift in Europe's approach.

19.02. Analysis: Politics Played a Role in Sept. 11 Attacks , NPR ATC

Excerpts: NPR's Mike Shuster reports that despite all the missed signals,
poor intelligence and
lousy communication between counter-terrorist agencies, politics did play a
role in early 2001 in
the inability of the U.S. government to anticipate al Qaeda attacks in the
United States. Testimony
before the commission investigating the government's actions before and
after the Sept. 11, 2001
attacks paints a picture of an incoming Bush administration unwilling to
see the threat from al
Qaeda as urgently as the outgoing Clinton administration did.
Editor's Note: Much of the current public terrorist discussion is not so
much about how to prevent
future terrorist attacks but much more about the public perceived reality
of the events related to
9/11. There is certainly immense evolutionary pressure on the two political
parties in the U.S. to
spin reality in a way favorable to partisan interests. On the other hand
one can claim (using the
demise of the Soviet Union as a recent historical example) that the
divergence of omposed
realities?compared to the observed ones can act as a critical parameter
that can destabilize the
overall political system.

19.03. Clarke's Contradictions , The Washington Times

Excerpts: Mr. Clarke said that from Oct. 1998 until Dec. 2000, the National
Security Council in the
Clinton administration failed to make any new recommendations on how to
deal with the burgeoning al
Qaeda threat. By contrast, in the summer of 2001, Mr. Clarke said, the Bush
administration changed
U.S. policy from the "rollback of al Qaeda over the course of five years"
to its elimination. All
of these points, however, are ignored or glossed over in his new book
?which depicts the
administration as laggards in dealing with the al Qaeda terrorist threat.

19.04. Bush's War -- Against Richard Clarke , Salon.com

Excerpts: The controversy raging around Richard Clarke's book -- and his
testimony before the 9/11
Commission that Bush ignored warnings about terrorism that might have
prevented the attacks --
revolves around his singularly unimpeachable credibility. In response, the
Bush administration has
launched a full-scale offensive against him: impugning his personal
motives, claiming he is a
disappointed job-hunter, that he is publicity mad, a political partisan
(Clarke, in fact, voted for
Republican Sen. John McCain for president in the Republican primaries in
2000) -- as well as
ignorant, irrelevant and a liar.
