Welcome to the Machine, NY Times
Book report on: 'Programming the Universe,' by Seth Lloyd (...) tackles computer logic, thermodynamics, chaos theory, complexity, quantum mechanics, cosmology, consciousness, sex and the origin of life (...). Lloyd, a professor of mechanical engineering at M.I.T., takes as his topic the fundamental workings of the universe, which he thinks has been horribly misunderstood. Scientists have looked at it as a ragtag collection of particles and fields while failing to see what it is as a majestic whole: an enormous computer. Every physical event, everywhere, feeds information into it. And the output of the cosmic computer is nothing less than reality itself.

Quantum Mechanics In The Brain, Nature
Excerpts: Why should evolution have turned to quantum computation, so fickle and capricious, if classical neural-network computations are evidently entirely sufficient to deal with the problems encountered by nervous systems?
The empirical demonstration of slowly decoherent and controllable quantum bits in neurons connected by electrical or chemical synapses, or the discovery of an efficient quantum algorithm for computations performed by the brain, would do much to bring these speculations from the 'far-out' to the mere 'very unlikely'. Until such progress has been made, there is little reason to appeal to quantum mechanics (...).

Changing Sides Or Changing Minds? Party Identification And Policy Preferences In The American Electorate, Ameri. J. Polit. Sc.
Excerpts: Scholars have long debated the individual-level relationship between partisanship and policy preferences. We argue that partisanship and issue attitudes cause changes in each other, but the pattern of influence varies systematically. Issue-based change in party identification should occur among individuals who are aware of party differences on an issue and find that issue to be salient. Individuals who are aware of party differences, but do not attach importance to the issue, should evidence party-based issue change. Those lacking awareness of party differences on an issue should show neither effect. (...)

Artificial Intelligence: Working Backwards From HAL, ZDNet UK
Excerpts: Work on machine intelligence started with chess, and Maniac 1, the first chess program to beat a human player, was demonstrated in 1956 by Stanislaw Ulam at Los Alamos National Laboratory in the US. This was an early success in the quest for machine intelligence that started a long sequence of work on chess-playing computers by many researchers around the world.
In 1966 Joseph Weizenbaum at MIT developed the first computer program capable of engaging in a conversation with a human ˇX Eliza. This clever program was able to hold a seemingly intelligent conversation with a human, and many felt that given enough computer power and a large enough vocabulary these algorithms would make it possible for a machine to meet Turing's test for intelligence.

In a Jumble of Grains, a Good Hard Shake Restores Order, Science
Excerpts: Whether they're chess pieces on a board or nuts in a jar, things usually move and mix when shaken. But vibrations can cause flowing beads to "freeze" into an orderly pattern like atoms in a crystal, a pair of physicists reports. The surprising observation could lead to deeper insights into disorderly solids such as glasses, in which the atoms or molecules are locked or "jammed" into a random state because they lack the energy to reach a more orderly one.

Excerpts: In theory, carbon nanotubes are 100 times stronger than steel, but in practice, scientists have struggled make nanotubes that live up to those predictions, in part, because there are still many unanswered questions about how nanotubes break and under what conditions. Because nanotubes are single molecules - about 80,000 times smaller than a human hair - finding out what makes them break involves the study of molecular bonds, atomic dynamics and complex quantum phenomena. The fact that there are hundreds of different kinds of nanotubes, sometimes with radically different properties, adds to the complexity. (...)

Semiconductor Advance May Help Reclaim Energy From 'Lost' Heat, Science
Excerpts: Harnessing even a fraction of the waste heat given off by engines, boilers, and other high-temperature machines could save billions of dollars a year in energy costs. Researchers are counting on thermoelectrics--semiconductor devices that turn heat into electricity--to perform that trick. First, however, these devices must do their job much more efficiently.
Two years ago, a group led by Mercouri Kanatzidis, a chemist at Michigan State University (MSU) in East Lansing, took a huge stride in that direction by unveiling a thermoelectric semiconductor with higher energy-conversion properties than any such bulk material ever invented.

Excerpts: A constellation of intrinsic and extrinsic cellular mechanisms regulates the balance of self-renewal and differentiation in all stem cells. Stem cells, their progeny, and elements of their microenvironment make up an anatomical structure that coordinates normal homeostatic production of functional mature cells. Here we discuss the stem cell niche concept, highlight recent progress, and identify important unanswered questions.

Hierarchical Self-Organization in the Finitary Process Soup, SFI Working Papers
Abstract: Current analyses of genomes from numerous species show that the diversity of an organismâ€™s functional and behavioral characters is not proportional to the number of genes that encode the organism. We investigate the hypothesis that the diversity of organismal character is due to hierarchical organization. We do this with the recently introduced model of the finitary process soup, which allows for a detailed mathematical and quantitative analysis of the population dynamics of structural complexity. Here we show that global complexity in the finitary process soup is due to the emergence of successively higher levels of organization, that the hierarchical structure appears spontaneously, and that the process of structural innovation is facilitated by the discovery and maintenance of relatively noncomplex, but general individuals in a population.

Chance And Necessity In The Evolution Of Minimal Metabolic Networks, Nature
Excerpts: It is possible to infer aspects of an organism's lifestyle from its gene content. Can the reverse also be done? Here we consider this issue by modelling evolution of the reduced genomes of endosymbiotic bacteria. The diversity of gene content in these bacteria may reflect both variation in selective forces and contingency-dependent loss of alternative pathways. Using an in silico representation of the metabolic network of Escherichia coli, we examine the role of contingency by repeatedly simulating the successive loss of genes while controlling for the environment.

Altruism Through Beard Chromodynamics, Nature
Excerpts: However, recognition of altruists could provide an alternative route towards the evolution of altruism. Arguably the simplest recognition system is a conspicuous, heritable tag, such as a green beard. Despite the fact that such genes have been reported, the 'green beard effect' has often been dismissed because it is unlikely that a single gene can code for altruism and a recognizable tag. Here we model the green beard effect and find that if recognition and altruism are always inherited together, the dynamics are highly unstable, leading to the loss of altruism.
