1. More Than Good Intentions: Holding Fast to Faith in Free Will, NYTimes
Excerpts: We think of will as a force, but actually, Dr. Wegner says, it is
a feeling - "merely a feeling," as he puts it - of control over our
actions. (...) But as we all know, correlation does not equal causation.
When neurologists make patients' limbs jerk by electrically zapping certain
regions of their brains, the patients often insist they meant to move that
arm, and they even invent reasons why. Neurologists call these erroneous,
post hoc explanations confabulations, but Dr. Wegner prefers the catchier
"intention inventions."
More Than Good Intentions: Holding Fast to Faith in Free Will, John Horgan,
NYTimes, 02/12/31
Excerpts: "All Medicine Men use it in their practice to foretell the
future, locate lost or stolen objects, name the perpetrator of a crime, to
diagnose and treat illness," he wrote in a letter to the British Journal of
Addiction, (...), speculating "perhaps even more spectacular results could
be obtained with synthetic variations."
But the history of yage far predates Western counter-culture. For
centuries, the potion, together with the gnarled jungle vine used to brew
it, have been central to the religions of dozens of South American Indian
ethnic groups.

Online/Reuters, 03/01/02
Excerpts: In real-world Washington, retired Navy Admiral John Poindexter is
constructing a system called Total Information Awareness, with the hopes of
being able to identify terrorists before they commit acts of terrorism,
based on a series of suspicious transactions. In the private sector,
companies are already using predictive intelligence to analyze your data
profile and solve more mundane business problems - like figuring out
whether you're the kind of person who might be induced to (...) go skiing
at Killington, when the ski resort could use more paying visitors.

2. The Stock Market As A Complex Adaptive System, J.Appl Corp Finance
Excerpts: (¡K) there is no systematic way to exploit opportunities for
superior gains. But we need to reorient the discussion to how this
operational efficiency arises. The crux of the debate boils down to whether
we should consider investors to be rational, well informed, and
homogeneous-(¡K)-or potentially irrational, operating with incomplete
information, and relying on varying decision rules.
The latter characteristics are part and parcel of a relatively newly
articulated phenomenon that researchers at the Santa Fe Institute and
elsewhere call complex adaptive systems.

4. Turing Tests Filter Spam Email, New Scientist
Excerpts: The tests involve deciphering a random word that has been
distorted or partly obscured. Though this is a relatively simple task for a
person, it remains beyond most computers. It is known as a "completely
automated public Turing tests to tell computers and humans apart" or visual
"CAPTCHA".
In 1950, the British mathematician Alan Turing suggested that if a
computer's performance was indistinguishable from that of a human, it could
be deemed intelligent. But since then researchers have struggled to come up
with any machine capable of passing such a Turing test.

5. Adventures In The Pathophysiology Of Brain Ischemia, Stroke
Excerpts: These animal data agree strikingly with published results in
patients with acute stroke studied by positron emission tomography. This
remarkable correspondence belies the assertion that data from lower species
may not be relevant to human stroke. (¡K), together with 35 upregulated
and
41 downregulated genes newly connected with ischemia. These findings
underscore the enormous complexity of ischemic biology and suggest possible
novel mechanisms for future exploration. (¡K)
Conclusion- The careful study of rodent ischemia models can yield valuable,
clinically relevant insights into the pathophysiology of ischemic stroke.

Ginsberg, Stroke 2003 January 1; 34(1): p. 214-223
Excerpts: Functional imaging studies have shown that certain brain regions,
(¡K), consistently show greater activity during resting states than during
cognitive tasks. This finding led to the hypothesis that these regions
constitute a network supporting a default mode of brain function. In this
study, we investigate three questions pertaining to this hypothesis: Does
such a resting-state network exist in the human brain? Is it modulated
during simple sensory processing? How is it modulated during cognitive
processing? (¡K)first resting-state connectivity analysis of the default
mode (¡K).

6. Rebuilding the Food Pyramid, Scientific American
Excerpts: How did the original USDA pyramid go so wrong? In part,
nutritionists fell victim to a desire to simplify their dietary
recommendations. Researchers had known for decades that saturated
fat--found in abundance in red meat and dairy products--raises cholesterol
levels in the blood. High cholesterol levels, in turn, are associated with
a high risk of coronary heart disease (heart attacks and other ailments
caused by the blockage of the arteries to the heart). (...) showed that
polyunsaturated fat--found in vegetable oils and fish--reduces cholesterol.
Rebuilding the Food Pyramid, Walter C. Willett and Meir J. Stampfer,
Scientific American, 02/12/17,
Excerpts: Johns Hopkins School of Medicine scientists have shown for the
first time that primitive fat cells must copy themselves at least twice
before they can mature into full-fledged fat-storing cells. The finding,
published online the week of Dec. 23 in the Proceedings of the National
Academy of Sciences, may help provide new targets for understanding and
treating obesity. The finding also helps explain how the body ensures that
it can always store fat, a key to surviving when food is scarce (and an
unfortunate ability when it is not). By requiring a primitive fat cell to
copy itself at least twice before it matures and can't divide anymore,
nature ensures a ready reservoir of the cells, say the researchers. While
proliferation of these cells has long been recognized, this is the first
evidence that those divisions are necessary for the cells' maturation.

7. Experimental Drug Relieves Rheumatoid Arthritis, Medline plus
Contributing Editor's Note: Rheumatoid Arthriris (RA) is a complex
autoimmune disease in which the immune system acts against its own body's
cells. The etiology of RA remains unknown. Metabolic and nutritional
factors, the endocrine system, geographic, psychologic, and occupational
data have been extensively studied with no conclusive findings. It now
appears that an unknown antigen initiates the autoimmune response resulting
in RA. There has been continuous suspicion of an infectious origin of the
disease process, which has included various bacteria and viruses, but
without evidence of precipitating events.
Excerpts: An experimental drug that blocks an immune protein suspected of
playing a role in rheumatoid arthritis improves symptoms of the autoimmune
disease, a small study shows. Although the study is preliminary, the
results are "very encouraging," the study's lead author told Reuters
Health. (...) The drug, known as a monoclonal antibody, targets an immune
system protein called interleukin-6. This protein has long been suspected
of playing a role in the inflammation caused by rheumatoid arthritis. This
link has not been proved, however. In rheumatoid arthritis, the immune
system attacks the tissues that line the joints, leading to pain,
inflammation and deformity. The disease affects more women than men, and it
may attack other organs in the body.

8. Orangutans Found to Share 'Culture', The Washington Post
Excerpt: The orangutans in central Borneo like to "surf" down dead
trees
for fun, grabbing hold of a safety line at the last second. The orangutans
in western Borneo, on the other hand, express annoyance by pressing a leaf
against their pursed mouths to make a loud kissing sound.
While some orangutans bite through vines to execute highly unusual
"Tarzan"
techniques, others appear to have "Martha Stewart" tendencies: They
repeatedly arrange pillows of twigs in unique patterns that seem to have no
practical purpose.
From these diverse behaviors, which are each shared by small groups of
orangutans but not the entire species, scientists have concluded that the
origins of "culture" go back 14 million years, twice as long as
previously
estimated. (...)
The discovery brings the number of species who are known to have
"culture"
to a grand total of three -- orangutans, chimpanzees and humans. That
number may well be larger -- or smaller -- depending on how culture is defined.
Editor's Note: Some experts also provide strong arguments for the presence
of culture in whales and dolphins (see Culture In Whales And Dolphins,
Complexity Digest 2000.41.1)

Abstract: Geographic variation in some aspects of chimpanzee behavior has
been interpreted as evidence for culture. Here we document similar
geographic variation in orangutan behaviors. Moreover, as expected under a
cultural interpretation, we find a correlation between geographic distance
and cultural difference, a correlation between the abundance of
opportunities for social learning and the size of the local cultural
repertoire, and no effect of habitat on the content of culture. Hence,
great-ape cultures exist, and may have done so for at least 14 million years.

Excerpts: A bonobo has surprised his trainers by appearing to make up his
own "words". It is the first report of an ape making sounds that seem
to
hold their meaning across different situations, and the latest challenge to
the orthodox view that animals do not have language.
(...) He has grown up in captivity among humans, and is adept at
communicating with symbols. He also understands some spoken English, and
can respond to phrases such as "go out of the cage" and "do you
want a banana?"

9. Genetic And Behavioral Conflict Over Male Production Between Workers And
Queens, Behav. Ecology & Sociobiol.
Abstract: Microsatellite genotyping of workers confirmed that the queen was
always singly mated, as in other stingless bees. As a consequence, workers
are more related to the sons of other workers than they are to the queen's
sons, and conflict is expected (¡K). A likelihood analysis shows that both
the queen and the workers contribute substantially to male production, with
workers typically contributing more, an average of 64%. The likelihood
curves are sharp enough to show that the worker fraction varies among
colonies and over time, consistent with a shifting balance of power between
queen and workers.

10. The Spider And Fly Revisited: Ploy-Counterploy Behavior In A Unique
Predator-Prey System, Behav. Ecology & Sociobiol.
Abstract: Observations of specialized behaviors for attack (flies) and
defense (spiders) suggest that this predator-prey relationship may
incorporate elements of ploy and counterploy behavior. Here we explore this
relationship in detail and test hypotheses regarding efficacy of attack and
defense behaviors. Egg-sac guarding by the spider includes defensive
behaviors specific to this fly predator (¡K). Removal of female spiders
results in a significantly higher probability of unguarded egg-sacs being
parasitized, demonstrating the adaptive value of spider defensive
behaviors. (¡K)) results of this study suggest that selection
pressures
from a highly specialized predator may also result in evolution of
predator-specific prey responses.

11. Male Sperm Whale Acoustics: Implications For Echolocation And
Communication, Behav. Ecology & Sociobiol.
Abstract. Data show that sperm whales in this habitat produce three click
types: usual clicks, creak clicks and, occasionally, slow clicks. Usual
clicks and creak clicks exhibit short duration, profound directionality
(¡K). The acoustic properties and low repetition rate of usual clicks are
suited for long-range echolocation, whereas creak clicks have properties
equivalent to signals in buzzes, the terminating pulse trains known from
echolocating bats during prey capture. From these source parameters and the
high acoustic activity during foraging dives, it is concluded that
echolocation is an important sensory cue in prey location. Thus, sperm
whales producing slow clicks (¡K) utilizes long-range sound communication.

12. Three-Dimensional Mapping of Dislocation Avalanches, Science
Abstract: There is growing evidence for the complex, intermittent, and
heterogeneous character of plastic flow. Here we report a three-dimensional
mapping of dislocation avalanches during creep deformation of an ice
crystal, from a multiple-transducers acoustic emission analysis.
Correlation analysis shows that dislocation avalanches are spatially
clustered according to a fractal pattern and that the closer in time two
avalanches are, the larger the probability is that they will be closer in
space. Such a space/time coupling may contribute to the self-organization
of the avalanches into a clustered pattern.

13.Earthquake Conversations, Scientific American
Excerpts: For decades, earthquake experts dreamed of being able to divine
the time and place of the world's next disastrous shock. But by the early
1990s the behavior of quake-prone faults had proved so complex that they
were forced to conclude that the planet's largest tremors are isolated,
random and utterly unpredictable. (...) that earthquakes interact in ways
never before imagined-- is beginning to overturn that assumption.
This insight corroborates the idea that a major shock relieves stress--and
thus the likelihood of a second major tremor-- in some areas.

14. Habitable Planets May Be Common, New Scientist
Excerpts: One in four of the planetary systems identified to date outside
the Solar System are capable of harbouring other Earths, (¡K), a much
higher proportion than anyone expected.
The researchers decided the race to detect an extrasolar Earth-like planet
is taking too long. So, instead of scanning the skies, they modelled all
the planetary systems known so far to work out which could be hiding
habitable planets. (¡K)
The planet must also be within the "habitable zone": the region
surrounding
a star within which a planet can support liquid water at all times.

15. New Light on Medicine, Scientific American
Excerpts: While struggling to find a cure for porphyria, scientists came to
realize that porphyrins could be not just a problem but a tool for
medicine. If a porphyrin is injected into diseased tissue, such as a
cancerous tumor, it can be activated by light to destroy that tissue. The
procedure is known as photodynamic therapy (¡K) effective weapon against a
diverse array of malignancies today and, most recently, for macular
degeneration and pathologic myopia, common causes of adult blindness.
Ongoing research includes pioneering treatments for coronary artery
disease, AIDS, autoimmune diseases, transplantation rejection and leukemia.
Editor's Note: Porphyria is a disease with symptoms that are triggered by
light and which might be at the origin of vampire legends.

16. Police Dragnets for DNA Tests Draw Criticism, NYTimes
Excerpt: In the United States, mass screenings have had less success and
stirred up far more controversy. In 1994 and 1995, the Metro-Dade police in
the Miami suburbs took more than 2,000 DNA samples in search of the
strangler of six prostitutes, and initially focused on three possible
matches before each man was ruled out. Still, the killer was caught only
after neighbors found a prostitute bound and gagged in his apartment while
he appeared in court on an unrelated robbery charge.

18. Quantum Investing, Book Report
Excerpts: "Steve Waite looks at the sweep of economic history and nails the
big ideas that will create the next revolution. Waite's done all your
homework for you -- Kurzweil to Kauffman, Arrow to Arthur, Drexler to
Drucker. Don't leave the 20th century without it."
--Christopher Meyer, Director, The Cap Gemini Center for Business Innovation
"Waite argues that to understand where the business world is going, and
where to find value, it will prove crucial to focus on quantum physics and
the industries that will flow from it. In a very timely way, Waite
highlights Schumpeter's process of creative destruction with old gods going
extinct and new ones coming into existence, and demonstrates the coming
importance of intangible asset accounting and complexity theory with its
models of self organization."
Quantum Investing, Stephen R. Waite, Texere, New York, London, 2003, Stuart
Kauffman, Founder and Chief Scientific Officer, BiosGroup Inc, Global-Investor
Excerpt: Of course. It was obvious that a single molecular camera was
inadequate to register any sort of image. Therefore, the image must be a
composite of millions of cameras, operating simultaneously. But the cameras
would also have to be arranged in space in some orderly structure, probably
a sphere. That was where the programming came in. But that in turn meant
that Xymos must be generating the equivalent of- "You're making an
eye."
"Kind of. Yes.".
Contributing Editor's Note: Descriptions of complexity abound in science
fiction and thrillers and are usually more enlightening than current
non-fiction attempts. Why? Because they deal in applications. We can see
that it is essential to look beyond the reduction patterns we were taught
in general science to wholistic, evolutionary patterns, fuzzy though they
may be. But Crichton writes a thriller based on Chris Langdon's Swarms and
draws upon many of the other work we study in the interplay of biological
processes by computer, nanomachines and distributed processing. All these
applications of complexity are driven by a military-industrial complex
willing to sacrifice lives for profit. The complexity reader will see
friends like Doyne Farmer and John Casti mentioned in notes but will also
"hear" them in some of the complexity descriptions given by book
characters. Prey is a palatable book for a reader new to complexity who
asks, "what is the point?"

19. Complex Challenges: Global Terrorist Networks
Excerpts: What game does the Bush administration think it's playing in Korea?
(...) During the cold war, the U.S. government employed experts in game
theory to analyze strategies of nuclear deterrence. Men with Ph.D.'s in
economics, like Daniel Ellsberg, wrote background papers with titles like
"The Theory and Practice of Blackmail." The intellectual quality of
these
analyses was impressive, but their main conclusion was simple: Deterrence
requires a credible commitment to punish bad behavior and reward good behavior.
(...) Yet the Bush administration's Korea policy has systematically
violated that simple principle.
Games Nations Play, Paul Krugman, NYTimes, 03/01/03
Excerpt: A historian once remarked that Britain acquired its empire in ''a
fit of absence of mind.'' If Americans have an empire, they have acquired
it in a state of deep denial. But Sept. 11 was an awakening, a moment of
reckoning with the extent of American power and the avenging hatreds it
arouses. Americans may not have thought of the World Trade Center or the
Pentagon as the symbolic headquarters of a world empire, but the men with
the box cutters certainly did, and so do numberless millions who cheered (...).
