1. Kin Selection May Inhibit The Evolution Of Reciprocation, J. Theor. Biol.

Abstract: Kin selection and reciprocal cooperation provide two candidate
explanations for the evolution of cooperation. Models of the evolution of
cooperation have typically focussed on one or the other mechanism, despite
claims that kin selection could pave the way for the evolution of
reciprocal cooperation. We describe a computer simulation model that
explicitly supports both kin selection and reciprocal cooperation. The
model simulates a viscous population of discrete individuals with social
interaction (¡K) We recount how the analytical and empirical study of this
model led to the conclusion that kin selection may actually inhibit the
evolution of effective strategies for establishing reciprocal cooperation.

2. Learning To Control Brain Activity, Brain & Cogn.

Abstract: Brain¡Vcomputer interface (BCI) technology relies on the ability
of individuals to voluntarily and reliably produce changes in their
electroencephalographic (EEG) activity. The present paper reviews research
on cognitive tasks and other methods of generating and controlling specific
changes in EEG activity that can be used to drive BCI systems. To date,
motor imagery has been the most commonly used task. This paper explores the
possibility that other cognitive tasks, including those used in imaging
studies, may prove to be more effective.

arXiv

Abstract: We note the importance of time-scales, meaning, and availability
of information for the emergence of novel information meta-structures at a
global scale. We discuss previous work in this area and develop future
perspectives. We focus on the transmission of scientific articles and the
integration of traditional conferences with their virtual extensions on the
Internet, their time-scales, and availability. We mention the Semantic Web
as an effort for integrating meaningful information.

4. Blowing Off Self-Esteem, ScienceNow

Excerpts: (¡K) "indiscriminate praise might just as easily promote
narcissism." And thinking you're great doesn't necessarily mean you are. (¡K)
Self-esteem as panacea is "a very compelling illusion," because it
correlates with happiness and other good things, says Baumeister. But he
believes psychologists "were a little too eager in promoting the program
before the data were in." Baumeister says his current research contains
quite a different lesson about how to be a successful person: "Forget about
self-esteem--concentrate on self-control."

Blowing Off Self-Esteem, Constance Holden, ScienceNow, 03/05/09


Excerpts: Songs with violent lyrics increase aggressive thoughts and
emotions, suggests a study in US college students.

The study contradicts a popular suggestion that music loaded with violent
imagery, such as some rap and heavy metal, are cathartic in venting
aggression. (¡K)

Although, the effects were measured over a short time only, the team
believes listening to violent lyrics could have a long-term effect -
contributing to the development of a more aggressive and confrontational
personality.

5. Mathematics Reveals The Cuttlefish's Wink, NewScientist.com

  Excerpts: The patterns on cuttlefish's backs change as they try to
camouflage themselves, or when they are startled.(...)
The team obtained 30 clear pictures of the patterns. (¡K) the researchers
used a mesh of reference points to convert each image into a plan view of
the animal's back.

They then used specialised ICA computer software to study the images. The
technique looks for elements within the images that change independently of
one another between pictures, and assumes these are the building blocks
used to create the patterns.

6. Single Signal Unites Treatments That Prolong Life, Science

Excerpts: Many techniques can bestow Methuselah-like life-spans on yeast
and other lab creatures: heating their environments, tinkering with their
genes, or restricting their food, for example. But the molecular mechanisms
that translate these manipulations into longevity remain mysterious. New
work suggests that, at least in yeast, a protein whose antiaging powers had
been unrecognized until now could explain how diverse stimuli stall aging.

Excerpts: Surgery, chemotherapy, and radiation barely slow the progression
of malignant glioma, a chillingly aggressive brain cancer. The fast growing
tumors destroy the brain and kill most people within a year. But for the
first time, researchers have completely cured mice of the disease using a
modified virus.

7. Cell Biology: Patches For Wounded Muscle, Nature

Excerpts: Cell membranes in tissues such as skin, gut and muscle are
routinely exposed to mechanical damage, which can produce holes in them.
When that damage is not repaired, the consequences can be severe - often
resulting in cell death - and may contribute to the development of the
muscle degenerative diseases termed muscular dystrophies. From a
combination of observations on human muscular dystrophy patients and
experiments with mice, (¡K) a protein called dysferlin is a component of
the mechanism for resealing the holes, and thus healing the muscle membrane.

8. Molecule Battles Heart Disease, The Atlanta Journal-Constitution

Excerpts: A molecule called beta3 integrin that scientists thought
contributed to heart disease now appears to help fight it.(...) The
scientists fed a high-fat diet to mice that lacked the beta3 molecule and
got unexpected results. The mice developed lung inflammation and clogged
arteries, and about two-thirds of the mice died within six weeks. That
suggests that long-term suppression of this beta3 molecule may contribute
to the development of heart disease, instead of preventing it, the study
concludes. The information may help guide new strategies for developing
drugs to combat heart disease.

9. Computational Biology: Biosensor Design, Nature

Excerpts: A series of bacterial receptor proteins have been 'redesigned' by
computer so that they bind molecules that are quite different from their
natural ligands. The approach might be useful for designing catalytic
proteins.
On page 185 of this issue, Looger and colleagues describe a powerful
computational method for designing proteins that can detect small
molecules. The authors have tested their approach on compounds such as
trinitrotoluene (TNT) and the neurotransmitter serotonin, and their
findings might see applications in, for instance, medicine and biotechnology.

Excerpts: Here we present a structure-based computational method that can
drastically redesign protein ligand-binding specificities. (¡K) we also
incorporated them into synthetic bacterial signal transduction pathways,
regulating gene expression in response to extracellular trinitrotoluene or
L-lactate. The use of various ligands and proteins shows that a high degree
of control over biomolecular recognition has been established
computationally. The biological and biosensing activities of the designed
receptors illustrate potential applications of computational design.

10. Folding At The Speed Limit, Nature

Excerpt: Many small proteins seem to fold by a simple process explicable by
conventional chemical kinetics and transition-state theory. This assumes an
instant equilibrium between reactants and a high-energy activated state. In
reality, equilibration occurs on timescales dependent on the molecules
involved, below which such analyses break down. The molecular timescale,
normally too short to be seen in experiments, can be of a significant
length for proteins. To probe it directly, we studied very rapidly folding
mutants of the five-helix bundle protein, whose activated state is
significantly populated during folding.

11. Pattern Recognition Method Zeroes in on Genes, NSF Press Release

  Excerpts: Using a new technique for recognizing patterns in biological
databases, a team of U.S. and Israeli computer scientists and geneticists
has developed a practical computational method that zeroes in on the genes
responsible for controlling the genetic machinery of a cell. (...)
Ordinarily, regulatory genes are identified experimentally, not
computationally. The new computational method makes the experimental
process much more efficient. It identifies regulatory candidates for
testing in the lab and predicts how each regulator will affect cellular
activity.

12. Self-Organization In Evolution: A Mathematical Perspective, Phil. Tran.
Math., Phys. & Engg. Sc.

Abstract: The neo-Darwinian view of evolution centres upon the role of the
gene. Here there seems to be little scope for self-organization. However,
models based on phenotypes, and including nonlinear and collective effects,
suggest that evolution can indeed be viewed as a process whereby the
ecosystem self-organizes. Here we focus on the phenomenon of speciation,
and discuss a series of phenotypic models which together illuminate some of
the issues surrounding the role of self-organization, including new
approaches to fitness landscapes and species selection. All of these models
represent speciation as a symmetry-breaking bifurcation, but in different
mathematical contexts (¡K).

Excerpts: A number of biologists now suspect that fisheries managers have
been inadvertently triggering similar bouts of rapid evolution. To keep
stocks from collapsing, managers often put a minimum size limit on catch,
giving younger fish a chance to breed before they are killed. Despite these
efforts, the average size of caught fish has been falling in recent decades
in many fisheries.

(¡K) suggest that the strategy selects for smaller individuals. The
evolutionary advantages are clear: If fish can become sexually mature while
still small, they have more chance to reproduce (¡K).

13. Universal Scaling Relations In Food Webs, Nature

Excerpts: Furthermore, food webs (except in isolated cases) do not share
general features with other types of network (including the Internet, the
World Wide Web and biological webs). These features are a small-world
character and a scale-free (power-law) distribution of the degree (the
number of links per vertex). Here we propose to describe food webs as
transportation networks by extending to them the concept of allometric
scaling (how branching properties change with network size). (¡K)We show
that, (¡K), spanning trees are characterized by universal scaling relations.

Abstract: The regular relationships between metabolic energy and body mass
M of unicellular organisms, poikilotherms and homeotherms were well known
as general equations. The metabolic energy rate and the life span are
proportional to M0.75 and to M0.25, respectively. As a result, the product
of the metabolic energy rate and the life time, namely, life metabolic
energy, is proportional to the mass of the living organism. The origin of
the scaling rules for environmental organizing systems is as follows: (1)
the scaling rules for internal energy, activation energy and free energy as
a function of temperature and mass of a mole of molecules. (2) The majority
of species of the living organisms have the same molecules such as
polysaccharides, lipids, proteins and nucleic acids in nearly same the
ratio. (3) The internal energy of reactants in living organisms is
equilibrium with the internal energy of water. Then, the integrated
metabolic energy over the synthesizing time depends on internal energy of
water and is proportional to mass M, despite the synthesizing time of the
system depending on reaction rate. The proportional constant is obtained
based on the thermodynamics for fundamental living organisms such as
unicellular organisms and plants. Information on the environmental
organizing system is also discussed.

Excerpts: The extraordinary abundance of ants in tropical rainforest
canopies has led to speculation that numerous arboreal ant taxa feed
principally as "herbivores" of plant and insect exudates. Based on nitrogen
(N) isotope ratios of plants, known herbivores, arthropod predators, and
ants from Amazonia and Borneo, we find that many arboreal ant species
obtain little N through predation and scavenging. Microsymbionts of ants
and their hemipteran trophobionts might play key roles in the nutrition of
taxa specializing on N-poor exudates. For plants, the combined costs of
biotic defenses and herbivory by ants and tended Hemiptera are substantial,
and forest losses to insect herbivores vastly exceed current estimates.

Excerpts: Army ants, nature's ultimate coalition task force, strike their
prey en masse in a blind, voracious column and pay no attention to the
conventional wisdom of evolutionary biologists. The common scientific
belief has been that army ants originated separately on several continents
over millions of years. Now it is found there was no evolution. Using
fossil data and the tools of a genetics detective, a Cornell University
entomologist has discovered that these ants come from the same point of
origin, because since the reign of the dinosaurs, about 100 million years
ago, army ants in essence have not changed a bit.

14. The Evolutionary Origin Of Complex Features, Nature

Excerpts: A long-standing challenge to evolutionary theory has been whether
it can explain the origin of complex organismal features. (¡K). Complex
functions evolved by building on simpler functions that had evolved
earlier, provided that these were also selectively favoured. However, no
particular intermediate stage was essential for evolving complex functions.
The first genotypes able to perform complex functions differed from their
non-performing parents by only one or two mutations, (¡K). In some cases,
mutations that were deleterious when they appeared served as
stepping-stones in the evolution of complex features.

15. A Question of Dose, Science

Summary: Metals have been adopted by biological systems because of their
catalytic versatility, but their reactivity can also make them toxic at low
concentrations. Hence they are classified as nutrients or poisons. But this
is a misleading division, because many enzyme catalysts have reaction
centers with diverse and variable metal associates. Such flexibility is
useful for organisms living in metal-poor environments that may have to
take what they can get, but it is potentially dangerous. Thus, the
availability of trace metals may govern an organism's nutritional strategy
in a particular environment. This special issue explores the double-edged
nature of metal chemistry, how it can be exploited for our benefit, and the
consequences if it is not tamed.
A Question of Dose, Caroline Ash and Richard Stone, Science May 9 2003: 925


Abstract: Planktonic uptake of some essential metals results in
extraordinarily low concentrations in surface seawater. To sequester or
take up these micronutrients, various microorganisms apparently release
strong complexing agents and catalyze redox reactions that modify the
bioavailability of trace metals and promote their rapid cycling in the
upper water column. In turn, the low availability of some metals controls
the rate of photosynthesis in parts of the oceans and the transformation
and uptake of major nutrients such as nitrogen. The extremely low
concentrations of several essential metals are both the cause and the
result of ultraefficient uptake systems in the plankton and of widespread
replacement of metals by one another for various biochemical functions.

Excerpts: Complex iron-sulfur metalloclusters form the active sites of the
enzymes that catalyze redox transformations of N2, CO, and H2, which are
likely components of Earth's primordial atmosphere. Although these centers
reflect the organizational principles of simpler iron-sulfur clusters, they
exhibit extensive elaborations that confer specific ligand-binding and
catalytic properties. These changes were probably achieved through
evolutionary processes, including the fusion of small clusters, the
addition of new metals, and the development of cluster assembly pathways,
driven by selective pressures resulting from changes in the chemical
composition of the biosphere.

Excerpts: We demonstrate microscopic fluidic control and memory elements
through the use of an aqueous viscoelastic polymer solution as a working

were able to demonstrate both a flux stabilizer and a bistable flip-flop
memory. These circuit elements are analogous to their solid-state
electronic counterparts and could be used as components of control systems
for integrated microfluidic devices. Such miniaturized fluidic circuits are
insensitive to electromagnetic interference and may also find medical
applications for implanted drug-delivery devices.

Excerpts: Liquid spreads and wets a surface, but wetting behaviour changes

Excess pressure (known as the disjoining pressure) can also develop in a
thin liquid film (less than 10 nm thick) when its two surfaces attract or
repel each other through van der Waals and electrostatic forces. The
interplay of the capillary and disjoining pressures is critical to the
stability of thin curved films, such as the wedge-like region at the edge
of a wetting solution, trapped between a solid surface and the air above.

resounding no. Pati and Samuel Braunstein (¡K), have proven that in a

19. Complex Challenges: Global Terrorist Networks

Excerpt: The extraordinary attacks of Sept. 11 clearly demanded
extraordinary measures. All reports, moreover, indicate that the prisoners
have not been physically mistreated. But America vowed after Sept. 11 that
the terrorists would not be allowed to drag us down to their level.
Meanwhile, the Department of Defense has held more than 600 male prisoners,
some as young as 13 - and of 42 different nationalities, including citizens
of our closest allies - in a concentration camp. (¡K) declared "unlawful
combatants" in order to deny them the protection of the Geneva Convention.

Excerpts: (¡K) during the Iraq war: many Americans turned to the BBC for
their TV news. They were looking for an alternative point of view -
something they couldn't find on domestic networks, (¡K).

Leave aside the rights and wrongs of the war itself, and consider the
paradox. The BBC is owned by the British government, and one might have
expected it to support that government's policies. In fact, however, it
tried hard - (¡K) - to stay impartial. America's TV networks are privately
owned, yet they behaved like state-run media.

politically inspired search for the private plane of a prominent Democratic
state legislator.

The department said the investigation would be conducted by the agency's

well known among some of the same state lawmakers in Texas who wanted the
plane tracked down.

Excerpts: The Constitution requires that a census be held every 10 years
and that it be the basis for Congressional reapportionment. District lines
are redrawn at that point, but once they are, whether by a legislature or a
court, there is a strong tradition of keeping them until the next census.
Lines have been redrawn at mid-decade to deal with extraordinary
circumstances, like a voting rights violation, but there is no basis for
redistricting simply so a political party can gain an advantage.

Editor's Note:  These two examples hint at an attempt to associate
political opponents with an enemy ("terrorist", "unlawful combatant") for
whom some constitutional protection ("Bill of Rights") has been denied.
 From a complex systems perspective this is not a surprising consequence of
a diminution of checks and balances.

20.4 Exploratorium's Complexity Web Site

Excerpt: This site attempts to place the idea of complexity in nature into
a broader scientific context, and to provide newcomers to the field with an
introduction to the concepts and theories that contribute to contemporary
complexity research.
Editor's Note: The Exploratorium is not only one of the best hands-on
science museums in the world but also integrates informal science education
in the museum with outstanding classroom science curriculum development in
interaction with science teachers. Currently methods of integrating the
Internet based science resources with hands-on science activities are
explored. The Exploratorium is also part of a global science education network.
