The first edition of Mark Ptashne's 1986 book describing the principles of gene regulation in phage lambda became a classic in both content and form, setting a standard of clarity and precise prose that has rarely been bettered. This edition is a reprint of the original text, together with a new chapter updating the story to 2004. Among the striking new developments are recent findings on long–range interactions between proteins bound to widely separated sites on the phage genome, and a detailed description of how gene activation works.
The study of the genetic basis for evolution has flourished in this century, as well as our understanding of the evolvability and programmability of biological systems. Genetic algorithms meanwhile grew out of the realization that a computer program could use the biologically-inspired processes of mutation, recombination, and selection to solve hard optimization problems. Genetic and evolutionary programming provide further approaches to a wide variety of computational problems. A synthesis of these experiences reveals fundamental insights into both the computational nature of biological evolution and processes of importance to computer science. Topics include biological models of nucleic acid information processing and genome evolution; molecules, cells, and metabolic circuits that compute logical relationships; the origin and evolution of the genetic code; and the interface with genetic algorithms and genetic and evolutionary programming.
This primer describes important equations of materials and the scientists who derived them. It provides an excellent introduction to the subject by making the material accessible and enjoyable. The book is dedicated to a number of propositions: 1. The most important equations are often simple and easily explained; 2. The most important equations are often experimental, confirmed time and again; 3. The most important equations have been derived by remarkable scientists who lived interesting lives. Each chapter covers a single equation and materials subject, and is structured in three sections: first, a description of the equation itself; second, a short biography of the scientist after whom i...

Tayala Léha is a medium, healer and author living in Germany. In 2016, she wrote in her poem "Announcement from the upper world": "In 2021, there will be a war in Germany. Warn everybody you know!". Unsettled by the message, she tells friends about it, but pushes this unbelievable-sounding information aside at first. In the spring of 2020, she was "guided" to the predictions of Alois Irlmaier, a Bavarian clairvoyant who was completely unknown to her at the time. He lived during the second world war and even proved his gifts before court! Irlmaier vigorously warned of a third world war for over 10 years until his death in 1959. He claims this will mainly affect Europe but will also have an impact on Alaska, Canada an the USA. Tayala Léha fears: "the information threads" from her own visions and from which Irlmaiers lead... In this booklet, Léha gives compact, useful information about Alois Irlmaier`s prophecies, her own inspiration and practical tips on how you can take preventive measures...
This volume is the seventeenth in a series dedicated to presenting the latest findings in the fields of comparative drama and performance. Featuring eleven essays from the 2021 Comparative Drama Conference in Orlando, it includes new research on contemporary plays by Anne Washburn, Will Arbery, Matthew Lopez, Anna Deveare Smith and Qui Nguyen. Chapters also present new research for classic plays such as Measure for Measure and Cyrano, arguments for teaching science through drama, changing approaches for training actors, and using the insights of neuroscience to lure audiences back to live theatre. This year's volume also features a new interview with playwright Anne Washburn and seven book reviews centered on drama and theatre studies.
Behavior and Culture in One Dimension adopts a broad interdisciplinary approach, presenting a unified theory of sequences and their functions and an overview of how they underpin the evolution of complexity. Sequences of DNA guide the functioning of the living world, sequences of speech and writing choreograph the intricacies of human culture, and sequences of code oversee the operation of our literate technological civilization. These linear patterns function under their own rules, which have never been fully explored. It is time for them to get their due. This book explores the one-dimensional sequences that orchestrate the structure and behavior of our three-dimensional habitat. Using Gib...

In the past century, nearly all of the biological sciences have been directly affected by discoveries and developments in genetics, a fast-evolving subject with important theoretical dimensions. In this rich and accessible book, Paul Griffiths and Karola Stotz show how the concept of the gene has evolved and diversified across the many fields that make up modern biology. By examining the molecular biology of the 'environment', they situate genetics in the developmental biology of whole organisms, and reveal how the molecular biosciences have undermined the nature/nurture distinction. Their discussion gives full weight to the revolutionary impacts of molecular biology, while rejecting 'genocentrism' and 'reductionism', and brings the topic right up to date with the philosophical implications of the most recent developments in genetics. Their book will be invaluable for those studying the philosophy of biology, genetics and other life sciences.
Explicit evidence exists for the progression of life—over a period of three-and-a-half billion years—from a strand of protein to an intelligent human, through trial, rejection and selection. The process continues and, if not hindered, a higher destiny awaits us in the distant future. Is life a property of matter? Is evolution a passive process? Or, does it have an aim or purpose? What is the role of beauty, intelligence and awareness in this evolutionary saga? Is eugenics going to hinder the natural process? Are we on our way to self-inflicted extinction? This book ponders on these questions and attempts to trace life’s quest for perfection—where beauty, vitality and wisdom meet.
