01. The Evolution Of Social Geometry: General Principles Of The Evolution
Of Complex Systems ,

Excerpts: This essay takes that path, i.e., looking for general principles
that determine the laws
of specific complex systems. (...) there are no laws that describe and
explain physical,
biological, and social complexity in the literally same way. But there may
be principles in a
rather abstract sense that show that all the different laws, which
determine the dynamics (...) of
complex systems, are all variations to the same air. I believe that, e.g.,
by analyzing some
aspects of socio-cultural evolution, it is possible to unveil such a
principle: the evolution of
complex systems must be understood as the evolution of their geometry.

Abstract: Two groups of high school students received a standard lesson in
evolutionary biology
followed by a software session. The experimental group used the suite of
artificial life software
presented in this paper; the control group used a commercial multimedia
hypertext. At the end (...)
asked to fill in a simple multiple-choice questionnaire testing the

aspects of evolutionary biology. The results show that the group using the
artificial life software
performed significantly better than the control group. We argue that (...)

02. Beyond The Ivory Tower: Constructing Complexity in the Digital Age ,

Expert: Over the centuries, architects have expressed their designs as one-
dimensional strings of
text, two- dimensional drawings, three-dimensional scale models, and--most
databases stored in computers. Successive advances in information
technology have enabled the
description and execution of increasingly ambitious projects. Today,
innovative applications of
computer-aided design and manufacturing technology are allowing architects
to transcend
long-standing limits on complexity and, thus, to respond more sensitively
and effectively to varied
human needs and construction contexts.  (...)This complexity may be
defined, for our purposes, as
the ratio of design content to construction content (...).

02.01. Study Finds a Nation of Polarized Readers , NY Times

Expert: "Bush at War" and "Sleeping With the Devil" are just two of the
political books that have
dominated the best-seller list of The New York Times (...). But according
to Valdis Krebs, (...),
these volumes - the first a blow-by-blow account of White House
deliberations in the aftermath of
Sept. 11, the second an expose of corruption and hypocrisy in
American-Saudi relations - share an
unusual distinction. They occupy a sparsely populated middle ground, rare
titles that have been
bought by people who generally tend to shop for much more partisan polemics.

03. Superfamilies of Evolved and Designed Networks , Science

Expert: Complex biological, technological, and sociological networks can be
of very different sizes
and connectivities, making it difficult to compare their structures. Here
we present an approach to
systematically study similarity in the local structure of networks, based
on the significance
profile (SP) of small subgraphs in the network compared to randomized
networks. We find several
superfamilies of previously unrelated networks with very similar SPs. (E)
Additional superfamilies
include power grids, protein-structure networks and geometric networks,
World Wide Web links and
social networks, and word-adjacency networks from different languages.

04. The Tangled Webs That Neutrophils Weave , Science

Expert: (...) extracellular killing may be riskier, because neutrophils can
potentially damage
surrounding host tissues. (...) a tool that neutrophils produce to kill
extracellular bacteria in a
way that minimizes damage to host cells. Brinkmann et al. observed that
when neutrophils are
stimulated with cytokines or bacterial endotoxin, these cells generate a
web of extracellular
fibers composed of DNA, histones, and granule proteins such as elastase
(see the figure). These
fibers, nicknamed neutrophil extracellular traps (NETs), bind to both
Gram-positive and
Gram-negative bacteria and display bactericidal activity.

04.01. Neutrophil Extracellular Traps Kill Bacteria , Science

Abstract: Neutrophils engulf and kill bacteria when their antimicrobial
granules fuse with the
phagosome. Here, we describe that, upon activation, neutrophils release
granule proteins and
chromatin that together form extracellular fibers that bind Gram-positive
and -negative bacteria.
These neutrophil extracellular traps (NETs) degrade virulence factors and
kill bacteria. NETs are
abundant in vivo in experimental dysentery and spontaneous human
appendicitis, two examples of
acute inflammation. NETs appear to be a form of innate response that binds
microorganisms, prevents
them from spreading, and ensures a high local concentration of
antimicrobial agents to degrade
virulence factors and kill bacteria.

05. Cell Biology: A Cellular Choreographer , Nature

Expert: During this time, the epithelial cells adhere tightly to each other
within the sheet to
provide a protective barrier between the 'outside' and 'inside'
environments. But the upper and
lower surfaces of the sheet have different surroundings and carry out
different functions. For
example, the upper surface is involved in taking up nutrients from the food
that passes through the
intestine, whereas the lower surface transports these nutrients into the
blood supply (...).
Knowledge of how this asymmetry, or polarization, is established is only
just emerging.

06. Ovaries May Replenish Eggs , NPR Audio

Expert: Researchers studying mouse ovaries report a startling discovery:
Ovaries are constantly
replenishing their supply of eggs. The finding challenges scientific dogma,
which holds that female
mammals are born with a finite supply of eggs that dwindles as they age.
Experts say the research
could revolutionize fertility treatments for middle-age women.

06.01. Lotion Speeds DNA Repair, Protects Mice From Skin Cancer , Science News

Expert: Snippets of DNA that activate a cell's DNA repair process may
protect mice from skin cancer
caused by ultraviolet radiation. (...) Dermatologists warn that not even
the best sunscreens
prevent all the potentially cancer-causing damage that ultraviolet light
(UV) does to skin. A new
study, however, suggests that incorporating certain snippets of DNA into
sunscreens could prompt
skin to repair UV-induced genetic damage before it leads to cancer. Indeed,
scientists have found
that slathering such DNA fragments onto UV-exposed hairless mice thwarts
skin cancer.

07. UCI Study Identifies How New Neurons Grow In Adult Brain , ScienceDaily

Excerpts: (...) study on cell growth in the adult brain may provide
important clues to the
potential use of stem cells in the treatment of memory-related diseases
such as Alzheimer's. The
study shows for the first time how newborn neurons in the adult brain grow
and integrate into the
area involved with learning and memory. The findings may prove significant
because these new
neurons begin in a primitive state similar to stem cells (...) that new
neurons in the adult brain
grow neural signaling appendages in a similar way to those found in
developing brains.

three genes working within
an embryo, body tissue or even a single cell. "This method allows us to

Expert: These mobile bits of quantum information, known as 'flying qubits',
have the potential to
travel over many kilometres, (...). "Ultimately a quantum link over a very
long distance could be
created," (...). Researchers have already entangled pairs of atoms, and
pairs of photons. But this
is the first time that scientists have seen a single atom entangled with a
single photon. "This has
probably been going on in other experiments, it is just that no one has
looked for it before," says

Expert: (...) would like to store information in the form of parcels of
charge placed at several
active sites around a single molecule. A USC/NASA-Ames collaboration has
taken a step in the
direction of such a chemical memory by producing a memory cell with three
different controllable
bit states, with a total of 8 (2 raised to the 3rd power) distinct levels.
This multilevel
molecular memory unit works by charging or discharging "molecular wires"
consisting of molecules
(attached to an underlying nanowire) into different chemically reduced or
oxidized (redox) states.

09. Method Produces Uniform, Self-Assembled Nanocells , Eureka Alert

Expert:      The peaks on this three-dimensional plot indicate a high
concentration of liposomes
forming in a microchannel.     The new NIST method uses micrometer-size
channels etched into a
device to produce self-assembled liposomes of specific sizes from as large
as about 240 nanometers
(nm) to as small as about 100 nm. A stream of natural fats (lipids)
dissolved in alcohol is
directed at an intersection of two channels that looks like a micro version
of a four-way stop. A
water-based liquid containing medicines or other substances is sent toward
the lipid stream from
two opposing directions. Rather than mixing with the water, the lipids
surround it, forming
self-assembled nanocells.

pulled from a fiery
furnace. The previous record holder was a mere 30 centimetres long. Carbon
nanotubes are stronger
than steel and better conductors than copper, but are often just a
thousandth of a millimetre in
length. (...) The carbon nanotubes are made by injecting ethanol into a
fast-flowing stream of
hydrogen gas. The gas carries the carbon-containing molecules into the
centre of a furnace where
temperatures soar above 1000 yC.

10. Superconductivity: Turn Up The Temperature , Nature

Expert: High-temperature superconductors are far more complex than their
counterparts, and there are many indications that their unique properties
result from the
competition between more than one type of order parameter. The electron
correlations that are
responsible for high-temperature superconductivity are still a mystery.
(...) using the
order-parameter approach to analyse the interaction between the
superconductivity in each layer of
the material. The authors have melded these ideas of tunnelling, charge
transfer and order into a
simple Landau-Ginzburg expression for the total energy of the system.

12. From The Tallest To (One Of) The Fattest: Fate Of The American
Population , Econ. & Human Biol.

Abstract: The American height advantage over Western and Northern Europeans
was between 3 and 9 cm
in mid-19th century, and Americans tended to be underweight. However,
today, the exact opposite is
the case as the Dutch, Swedes, and Norwegians are the tallest, and the
Danes, British and
Germans-even the East-Germans--are also taller, (...) by as much as 3-7 cm.
Americans also have
shorter lives. The hypothesis is worth considering that this adverse
development is related to the
greater social inequality, an inferior health care system, and fewer social
safety nets (...) in
spite of higher per capita income.

whereas at a high level
of crowding, another trail is established before traffic volume is
affected, which guarantees that
an optimal rate of food return is maintained. This bifurcation phenomenon
is explained by a
nonlinear modelling approach. (...) The balancing mechanism between
cohesive and dispersive forces
appears to be generic in natural, urban and transportation systems.

Environment , Alphagalileo &

Abstract: Animals, like humans, differ in personality. The existence of
genetic variation in
personality poses the question how variation in animal personality is
maintained in natural
populations. We measured a personality trait (exploratory behaviour in a
novel environment) in a
common garden bird, the great tit, and studied how personality affects
survival and offspring
production in the wild. We show that certain types do better in certain
years, whereas other types
do better in other years. Such fluctuating selection may explain why
different personality types
can coexist in natural populations.

Abstract: We use mathematical models to analyse how the recovery rate from
infection influences the
fitness of a host in a setting of interspecific competition. We show that
sub-optimal immunity
against pathogens can be advantageous for the host (...). Weaker immunity
allows the parasite to be
used as a biological weapon, and this increases the fitness of the host
relative to a competitor. A
parameter region is observed in which the outcome of competition depends on
the initial conditions.
We extend this model (...) find that the outcome depends on the migration
rate of the host species.
