02. The Perils of the Imitation Age , Harvard Business Review
Excerpts: Imitation exerts enormous influence over society--and business and
finance in particular. (...) More significantly, we can and do act upon such
knowledge. The resulting fads and fashions, bubbles, and crashes are ever more
frequent, severe, and complex. The information age has cast up more than its
share of paradoxes, including this one: When information is plentiful, we often
use it not to make better decisions but to imitate others--and their
mistakes.(...)
When there's too much information, imitation becomes a convenient heuristic.
This is the basis for a self-referential society.

02.01. Strategic Investment In Reputation , Behav. Ecol. & Sociobiol.
Excerpts: Although collective efforts are common in both animal and human
societies, many human and probably animal social dilemmas have no obvious
cooperative solution, which is a challenge for evolutionary biologists. In
public goods games, i.e. the experimental paradigm for studying the
sustainability of a public resource with human subjects, initial cooperation
usually declines quickly.(...) Here we show experimentally that humans use
different strategies in the public goods game conditional on whether the player
knows that his decisions will be either known or unknown in another social
game. (...) However, cooperation declines immediately when individual
identities switch from being recognizable (...).

02.02. The Power of Impossible Thinking , Knowledge@Wharton
Excerpts: Impossible thinking. It is what put men on the moon, allowed
Starbucks to turn a commodity product into a powerful global business and
permitted Roger Bannister to run the four-minute mile. While not every
mpossible thought?can become a reality, very often the greatest obstacle to
transforming our organizations, society and personal lives is our own thinking.
This may seem to be a simple idea in theory ?(...)?but it has far-reaching
implications for how we approach life and decision making.

03. D.I.Y. Meets N.R.L. (No Record Label) , NY Times
Excerpts: In the last decade, Maria Schneider, (...) has made three albums on
the Enja record label. Each sold about 20,000 copies ?very good numbers for
jazz. She didn't make a dime off any of them. (...)
Rather than go through labels, distributors and retailers, ArtistShare sells
discs over the Web and turns over all the proceeds (minus a small fee) to the
artist. (...)
If it sells one-quarter as many copies as any of her previous discs, she will
do better than break even.
Editor's Note: One might wonder how much longer they will bother pressing
little plastic disks to sell the music.

03.01. 'Magic Ink' That Makes Metal Grow , BBC News Online
Excerpts:
Electronic circuitry is usually etched with copper
An eco-friendly way of "growing" metal for circuitry or antennas has
been
developed by UK firm QinetiQ.
The metal printing technique replaces conventional copper etching by using a
special ink which attracts metals.
It means antennas for tiny mobiles or radio frequency identification (RFID)
tags, used for tracking goods, could be made cheaply and quickly. (...)
Because they connect by radio, they do not require the scanners, so familiar
with the barcoding system, to read their unique identification codes.
The metal printing technique could transform how RFID tags are made.

04. Neuroscience: Change Of Mind , Nature
Excerpts: A brain haemorrhage turned an ex-convict into an obsessive artist.
(...)
In cognitive tests (...), McHugh demonstrates a mix of abilities and
deficiencies. (...) has difficulty switching trains of thought. When asked to
list types of furniture, for example, he will rattle off chairs and tables like
the rest of us. But when asked to switch to listing animals, he continues to
talk about lamps and sofas. It's a trait that becomes apparent when talking to
McHugh: sentences tumble out relentlessly unless he is interrupted.

04.01. Concepts - A Model For Madness? , Nature
Excerpts: During REM sleep, there is also selective activation of the amygdala
and other parts of the limbic system. This is relevant for our understanding of
the heightened emotion ?especially the feelings of anxiety, anger and elation
?that so commonly dictate the development of a dream plot. An exaggeration of
emotional activation is also common in mental illness, when it may contribute
to impairment of rationality. An idea that helps to unite these findings is
that emotion is itself an internally generated percept that powerfully
influences conscious experience.
* Concepts - A Model For Madness?, Allan Hobson , 04/07/01, DOI:
10.1038/430021a, Nature 430, 21

04.02. Anesthetics Are Slowly Giving Up The Secrets Of How They Work , Science
News
Excerpts:
The first successful demonstration of ether's use as a surgical anesthetic was
conducted in 1846. William T.G. Morton, who administered the ether for the
removal of a tumor from a patient's jaw, is to the immediate left of the
patient.(?Bettmann/CORBIS)
Combining amnesia, sedation, immobility, and insensitivity to pain, general
anesthesia is an unnatural state: a physician-induced "central nervous
system
dysfunction," (...).
One of the central questions of anesthesia research has been whether all these
drugs work in the same manner. Until the last few decades, investigators
generally held that, despite chemical differences, the drugs share a mechanism
of action.
One long-standing theory was based on the simple observation that the more
soluble an anesthetic is in olive oil, the more effective it is.

05. Circadian Rhythms: As Time Glows By In Bacteria , Nature
Excerpts: Populations of cells can exhibit remarkably precise and stable
circadian oscillations. But can single cells achieve such precision in the
absence of intercellular communication? For cyanobacteria, it seems so.
Have you ever heard of a bacterium with jet lag? The idea might seem absurd; 20
years ago, experts in the field would have thought so too. Bacterial cells were
believed to be just too 'simple' to have the biological clocks necessary to
regulate daily (circadian) rhythms of gene expression, physiology and
behaviour.
* Circadian Rhythms: As Time Glows By In Bacteria, Carl Hirschie Johnson ,

06. Neurobiology: Sleep On It , Nature
Excerpts: (...) suggests that sleep has a key role in neural plasticity ?that
is, in maintaining appropriate connections between neurons through respectively
reinforcing and eliminating significant and accidental connections between
synapses. Owing to its traditional association with dreaming, REM [ rapid eye
movement, Ed.] sleep was first implicated in learning and neural plasticity,
with findings ?mainly from animal studies ?showing a correlation between the
amount of REM sleep and performance on a learned task. More recently, NREM [
non-rapid eye movement, Ed.] sleep, and specifically slow-wave activity, has
also been shown to play a critical part in both developmental and
learning-induced plasticity.

DOI: 10.1038/430027a, Nature 430, 27 - 28
