Dutch researchers authored this article, which appears in the December 6 issue of the journal _Nature_. ... soluble semiconductive polymers in microelectronic devices ... Here we describe an active-matrix display with 64 x 64 pixels, each driven by a thin-film transistor with a solution-processed polymer semiconductor. In a significant step towards low-cost flexible displays, this polymer-dispersed liquid-crystal arrangement gives a reflective, low-power display with paper-like contrast, which can handle 256 grey levels while being refreshed at video speed.

Devices that convert information from one form into another according to a definite procedure are known as automata. One such hypothetical device is the universal Turing machine ... The Turing machine ... operate[s] by scanning a data tape, whose striking analogy to information-encoding biopolymers inspired several designs for molecular DNA computers. Laboratory-scale computing using DNA ... has been demonstrated, but realization ... remains rare. Here we describe a programmable finite automaton comprising DNA and DNA-manipulating enzymes that solves computational problems autonomously.

The Institute for Genomic Research, based in Maryland, is sponsoring a series of lectures on the future of science. The series begins on Thursday, November 29, with a talk by Hans Moravec of CMU. It continues through at least May 2002 with talks by Bill Cheswick of Lumeta (author of _Firewalls and Internet Security_) and Ralph Merkle of Zyvex (and _The Diamond Age_ fame), among others.

Inventor-author Ray Kurzweil has proposed a major new national program to develop defensive strategies, technologies, and ethical standards to address the dangers of emerging genetic, nanotechnology and robotics technologies. "The program would be administered by the National Science Foundation and the National Institutes of Health," said Kurzweil. "It would have a budget equaling the current budget for NSF and NIH."

The Computational Perspective: A Talk With Daniel Dennett |

Topic: Science |

"A philosopher by training, Daniel C. Dennett is known as the leading proponent of the computational model of the mind. He has made significant contributions in fields as diverse as evolutionary theory, artificial intelligence, cognitive science, animal studies, computer science among others. Never one to avoid a good fight, he has clashed with such noted thinkers as John Searle, Roger Penrose, and Stephen Jay Gould. In this regard, Dennett is emblematic of the third culture intellectual.The strength of the third culture is precisely that it can tolerate disagreements about which ideas are to be taken seriously. There is no canon or accredited list of acceptable ideas. Unlike previous intellectual pursuits, the achievements of the third culture are not the marginal disputes of a quarrelsome mandarin class: they affect the lives of everybody on the planet."

Small Worlds: The Dynamics of Networks between Order and Randomness |

"Everyone knows the small-world phenomenon: soon after meeting a stranger, we are surprised to discover that we have a mutual friend, or we are connected through a short chain of acquaintances. In his book, Duncan Watts uses this intriguing phenomenon--colloquially called "six degrees of separation"--as a prelude to a more general exploration: under what conditions can a small world arise in any kind of network? The networks of this story are everywhere [...] How do such networks matter? Simply put, local actions can have global consequences, and the relationship between local and global dynamics depends critically on the network's structure. [...] Watts's novel approach is relevant to many problems that deal with network connectivity and complex systems' behaviour in general [...] This fascinating exploration will be fruitful in a remarkable variety of fields, including physics and mathematics, as well as sociology, economics, and biology."

From Swarms to Societies: Models of Complex Coherent Action |
|
|
Topic: Science |
1:20 pm EST, Nov 3, 2001 |
This book shows how, by rather simple models, we can gain remarkable insights into the behavior of complex systems. It is devoted to the discussion of functional self-organization in large populations of interacting active elements. The possible forms of self-organization in such systems range from coherent collective motions in the physical coordinate space to the mutual synchronization of internal dynamics, the development of coherently operating groups, the rise of hierarchical structures, and the emergence of dynamical networks. Such processes play an important role in biological and social phenomena. The authors have chosen a series of models from physics, biochemistry, biology, sociology and economics, and will systematically discuss their general properties. The book addresses researchers and graduate students in a variety of disciplines, such as physics, chemistry, biology and the social sciences." ISBN 3-540-42164-5.
