02. Artificial Life: Organization, Adaptation and Complexity from the
Bottom Up , Trends in
Cognitive Sciences

Abstract: Artificial life attempts to understand the essential general
properties of living systems
by synthesizing life-like behavior in software, hardware and biochemicals.
As many of the essential
abstract properties of living systems (e.g. autonomous adaptive and
intelligent behavior) are also
studied by cognitive science, artificial life and cognitive science have an
essential overlap. This
review highlights the state of the art in artificial life with respect to
dynamical hierarchies,
molecular self-organization, evolutionary robotics, the evolution of
complexity and language, and
other practical applications. It also speculates about future connections
between artificial life
and cognitive science.

Excerpts: "Radiant Cool" has the makings of a gripping noir thriller: a
missing body, a
tough-talking female sleuth and a mustachioed Russian agent mixed up in a
shadowy plot to take over
the world. But the novel, by Dan Lloyd, (...), is also a serious work of
scholarship, the unlikely
vehicle for an abstruse new theory of consciousness.

Excerpts: What then? If the brain is not a bureucracy of functional
specialists, what is it? It is
-- in my view -- a radical democracy. A cooperative kibbutz in which
everyone pitches in a bit on
just about everything. Or, in the language of cognitive science, the brain
is a distributed
processor. But distributed processors are hard to understand, requiring
special interpretive
strategies. One microscope of complexity is multidimensional scaling, and
through its lenses we can
see terra cognita, the space of mind.

04. Bridging The Gap Between Rationality And Adaptation In Social
Explanation , J. Evolutionary

Abstract: This paper focuses on the uneasy alliance of rational choice and
explanations in modern economics. While direct evolutionary explanations
rule out "purposeful"
rational choice by assuming "zero-intelligence" and pure rational choice
explanations leave no room
for "selective" adaptation, the indirect evolutionary approach integrates
both perspectives.
Subsequently we go stepwise "from teleology to evolution" and thereby study
the model spectrum
ranging from pure rational choice over indirect to direct evolutionary
approaches. We believe that
knowledge of this spectrum can help us to choose more adequate models of
economic behavior that
incorporate both teleological and evolutionary elements.

05.01. Web Site Synthesis Based On Computational Logic

Abstract: Web site design and maintenance has become
a challenging problem due to the increase in volume and complexity of
information presented in this
way. Web site applications can also benefit from systematic approaches to
development that make
design more methodical and maintenance less time consuming. One way to
tackle this problem is via
automated synthesis, automatically deriving a Web site from a high-level
application description.
Computational logic is well suited to this problem because of its support
of a uniform view of data
and computation, allowing reasoning
with both specification and program via meta-rogramming.

06. Neuroscience: Re-Recording Human Memories , Nature

Excerpts: New memories that weaken during the day can be strengthened by a
period of sleep. And
when memories are reactivated, they must be re-stored in order to persist.
(...) No longer is memory thought to be a hard-wiring of information in the
brain. Instead, it
seems to be a process of storage and re-storage. (...) sleep can rescue
memories that were lost
during the day. (...) stabilized memories can be re-stored when they are
reactivated - and that
those memories are lost if this process is interfered with.

06.01. Dissociable Stages Of Human Memory Consolidation And Reconsolidation
, Nature

Excerpts: Recent findings regarding the learning of skilled sensory and
motor tasks ('procedural
learning') have refined this definition, suggesting that consolidation can
be more strictly
determined by time spent in specific brain states such as wake, sleep or
certain stages of sleep.
There is also renewed interest in the possibility that recalling or
'reactivating' a previously
consolidated memory renders it once again fragile and susceptible to
interference, therefore
requiring periods of reconsolidation. Using a motor skill finger-tapping
task, here we provide
evidence for at least three different stages (...).

, Nature

Excerpts: Memory consolidation resulting from sleep has been seen broadly:
in verbal list learning,
spatial learning, and skill acquisition in visual and motor tasks. These
tasks do not generalize
across spatial locations or motor sequences, (...). Although episodic rote
learning constitutes a
large part of any organism's learning, generalization is a hallmark of
adaptive behaviour. In
speech, the same phoneme often has different acoustic patterns depending on
context. Training on a
small set of words improves performance on novel words using the same
phonemes but with different
acoustic patterns, (...).

07.01. Mutualism Can Mediate Competition And Promote Coexistence , Ecol. Lett.

Abstract: Mutualistic interactions are not believed to promote coexistence
of competitors because
mutualisms produce positive feedbacks on abundances whereas coexistence
requires negative
feedbacks. Here we show that a mutualism between an anemonefish
(Amphiprion) and its sea anemone
host mediates the effect of asymmetrical competition for space (...)
fosters their coexistence.
Amphiprion stimulates increases in host area, the shared resource, but
social interactions cap the
number of anemonefish to two adults per host. Space generated by the
mutualism becomes
differentially available to Dascyllus because the effectiveness of an
anemonefish in excluding its
competitor declines with increases in the area it defends.

08. Ultraviolet Vision In A Bat , Nature

Excerpts: Most mammals, with the exception of primates, have dichromatic
vision and correspondingly
limited colour perception. Ultraviolet vision was discovered in mammals
only a decade ago, and in
the few rodents and marsupials where it has been found (...). Bats orient
primarily by
echolocation, but they also use vision. Here we show that a phyllostomid
flower bat, Glossophaga
soricina, is colour-blind but sensitive to ultraviolet light down to a
wavelength of 310 nm.
Behavioural experiments revealed a spectral-sensitivity function with
maxima at 510 nm (green) and
above 365 nm (ultraviolet).

09. The Mother-In-Law Effect , Alphagalileo & Biol. Lett.

Abstract: Individuals often benefit by manipulating others. In most cases,
manipulation involves
direct, physical interactions between individuals. In the dung beetle,
Onthophagus taurus, mothers
provide more food to offspring when mated with large males. In this
article, we demonstrate that
this manipulation may extend across generations - the care a mother
provides to a developing son
influences the parental effort of his mate (the mother's daughter-in-law).
In contrast to previous
studies demonstrating the considerable advantages of increased maternal
care, this mother-in-law
effect is mediated by the ability to produce large sons from relatively
lower levels of care.

10. The Automatic Pilot Of Honeybees , Alphagalileo & Proc. Biol. Sc.

Abstract: The 'automatic pilot' facility allows a pilot to set a desired
compass course, and his
aircraft will then fly that course for the required distance. Using
harmonic radar, we have found
that honeybees returning to their hive from food sources apparently
navigate in this way, and
remarkably, compensate for wind drift while doing so. If captured and
released elsewhere, they
still fly this course for the distance that should take them home, ignoring
unfamiliar landmarks
encountered on the way. Conversely, if these bees perceive landmarks they
can recognise, they
sometimes abandon the 'auto-pilot' mode and return home using other methods.

11.01. Exponential DNA Replication by Laminar Convection , Physical Review

Abstract: It is shown that laminar thermal convection can drive a chain
reaction of DNA
replication. The convection is triggered by a constant horizontal
temperature gradient, moving
molecules along stationary paths between hot and cold regions. This
implements the temperature
cycling for the classical polymerase chain reaction (PCR). The
amplification is shown to be
exponential and reaches 100 000-fold gains within 25 min. Besides direct
applications, the
mechanism might have implications for the molecular evolution of life.

12. Complexity in the Immune System , arXiv

Abstract: The immune system is a real-time example of an evolving system
that navigates the
essentially infinite complexity of protein sequence space. How this system
responds to disease and
vaccination is discussed. Of particular focus is the case when vaccination
leads to increased
susceptibility to disease, a phenomenon termed original antigenic sin. A
physical theory of protein
evolution to explain limitations in the immune system response to
vaccination and disease is
discussed, and original antigenic sin is explained as stemming from
localization of the immune
system response in antibody sequence space. This localization is a result
of the roughness in
sequence space of the evolved antibody affinity constant for antigen and is
observed for diseases
with high year-to-year mutation rates, such as influenza.

Molecules , NYTimes

Excerpts: The study, to be published today, in The Journal of the American
Medical Association,
adds to an emerging collection of evidence that suggests that the size of
lipoproteins, both good
and bad, may play a significant role in heart disease, diabetes and,
consequently, longevity.
"Large particle size seems to give people an extra 20 years of life, with
very little disability to
go along with it," said Dr. Nir Barzilai, who directed the study at the
Albert Einstein College of
Medicine in the Bronx. Dr. Barzilai also traced large lipoproteins to a
specific gene that
influences lipoprotein size.(...) The gene may be one reason why some
centenarians in Dr.
Barzilai's study have lived to 100, even though they were overweight or ate
badly. "I hate to say
it," he said. "but I think it's true. If you have this gene, you can smoke
and you can be fat and
you can not exercise. This sounds to me terrible."

Here, the different
states, expressed as combinations of symbols, were defined on the basis of
the animal's location
(A: periphery, and B: inner part of the aquarium) and speed (Fast and
Slow). We observed that the
distributions of time intervals spent in the successive states were not
gaussian. Rather, they were
fit by power laws (...). Furthermore, our data suggest that the swimming
behavior can be attributed
to interactions between two intrinsic systems.

Abstract: A non-linear morphodynamic model of a microtidal coastal shelf is
used to study the
response of shoreface-connected sand ridges and the net sand balance of the
shelf to large-scale
interventions. The model describes the interaction between storm-driven
currents and the erodible
bottom. The model results indicate that for all interventions studied a
relatively fast local
recovery (time scale of decades to centuries) of the disturbed bathymetry
to its original pattern
takes place. Readjustment of the global system to its original equilibrium
state (the saturation
process) occurs on a longer time scale (several centuries).

on the linear stability analysis of the flat configuration of the sea
bottom subject to tidal
currents. Attention is focused on the prediction of the complex growth rate
that bottom
perturbations undergo because of both oscillatory fluid motions and
residual currents. While the
real part r of controls the amplification or decay of the amplitude of the
bedforms, the imaginary
part i is related to their migration speed.

Abstract: When drought hit the 5000-kilometer-long strip of marginally
habitable land along the

suffered greatly. Soon
some researchers were hypothesizing that intensive use of the land might

of the Sahel enough to dry it out. The locals, although they have clearly
used the land heavily,
have since been absolved of fooling with the climate (Science, 31 July
1998, p. 633

19.03. The Military Balance 2003-4 , International Inst f Strategic Studies
Press Conference

Excerpts: The US-led invasion of Iraq brought about a collapse in the
security structures of the
country including the structures for guarding arms dumps, and the state's
border regime. The
coalition was unprepared for the scale of the problem, and had no way of
securing the quantity of
ammunition and weapons storage sites.
Some five months on the situation has hardly improved and small arms and
light weapons are readily
available to criminals and insurgents alike. Alarmingly, the report
produced by David Kay of the
Iraq Survey Group earlier this month noted that 'there are approximately
130 known Iraqi Ammunition
Storage Points (ASP) many of which exceed 50 square miles and hold an
estimated 600,000 tons of
ordinance.... Of these approximately 120 still remain unexamined.' While
the number of un-inspected
sites may be interesting in terms of the struggle to find evidence of WMD,
it is even more
interesting as a comment on the ammunition that may be available to
terrorists who can get access
to unguarded or poorly guarded depots. A particular issue concerns
man-portable air defence systems
(MANPADS) which exist in large quantities.

19.04. Intelligence Puzzle: North Korean Bombs , NYTimes

Excerpts: New intelligence estimates that North Korea may have produced one
or two nuclear weapons
in recent months - or perhaps more - have immersed the administration in
another internal debate
about the quality of intelligence about illegal weapons.
With President Bush just days from embarking on his longest foray in Asia,
some of his advisers say
it is possible that North Korea is telling the truth about having turned
8,000 nuclear fuel rods
into enough weapons-grade plutonium for several warheads.
Others, (...), say there is still no proof, (...).

19.05. Feds Want All-Seeing Eye in Sky , Wired

Excerpts: "We need an illuminator, throwing into relief all the pictures
and activities on the
Earth's surface. And then we need to be able to switch on the spotlight, or
alert other systems, to
dive deep." (...).

Space-based radar, or SBR, is Cambone's preferred method for fulfilling
these aims. America's
current imaging satellites can cover only thin slices of the Earth at any
one time as the
spacecraft pass overhead. A constellation of 10 to 24 SBR satellites,
slated for 2012 or so, would
cover almost the entire globe at once.

* Feds Want All-Seeing Eye in Sky, Noah Shachtman  , 03/10/17, Wired


19.06. Spies Attack White House Secrecy , Wired

Excerpts: Moves to classify documents are up 400 percent from a decade ago,
to more than 23 million
such actions in 2002, according to the Information Security Oversight Office
, a division of the National Archives. (...)

To counter far-reaching, stealthy terrorist cabals, the country needs more
openness, not less, they
said Wednesday at Geo-Intel 2003, a first-of-its-kind conference here on
the use of satellites in
war, intelligence and homeland security.

"Our secrecy system is all about protecting secrecy officers, and has
nothing to do with protecting
secrets. It's a self-licking ice-cream cone," (...).
