Symbiosis as a Source of Evolutionary Innovation Speciation and Morphogenesis

Lynn Margulis,Rene Fester
These original contributions by symbiosis biologists and evolutionary theorists address the adequacy of the prevailing neo-Darwinian concept of evolution in the light of growing evidence that hereditary symbiosis, supplemented by the gradual accumulation of heritable mutation, results in the origin of new species and morphological novelty. A departure from mainstream biology, the idea of symbiosis—as in the genetic and metabolic interactions of the bacterial communities that became the earliest eukaryotes and eventually evolved into plants and animals—has attracted the attention of a growing number of scientists. These original contributions by symbiosis biologists and evolutionary theorists address the adequacy of the prevailing neo-Darwinian concept of evolution in the light of growing evidence that hereditary symbiosis, supplemented by the gradual accumulation of heritable mutation, results in the origin of new species and morphological novelty. They include reports of current research on the evolutionary consequences of symbiosis, the protracted physical association between organisms of different species. Among the issues considered are individuality and evolution, microbial symbioses, animal­bacterial symbioses, and the importance of symbiosis in cell evolution, ecology, and morphogenesis. Lynn Margulis, Distinguished Professor of Botany at the University of Massachusetts at Amherst, is the modern originator of the symbiotic theory of cell evolution. Once considered heresy, her ideas are now part of the microbiological revolution. Contributors Peter Atsatt, Richard C. Back, David Bermudes, Paola Bonfante-Fasolo, René Fester, Lynda J.

Global Bioethics: The Impact of the UNESCO International Bioethics Committee

Alireza Bagheri,Jonathan D. Moreno,Stefano Semplici
The UNESCO International Bioethics Committee is an international body that sets standards in the field of bioethics. This collection represents the contributions of the IBC to global bioethics. The IBC is a body of 36 independent experts that follows progress in the life sciences and its applications in order to ensure respect for human dignity and freedom. Currently, some of the topics of the IBC contributions have been discussed in the bioethics literature, mostly journal articles. However, this is a unique contribution by the scholars who developed these universal declarations and reports. The contributors have not only provided a scholarly up to date discussion of their research topics, but as members of the IBC they have also discussed specific practical challenges in the development of such international documents. This book will be suited to academics within bioethics, health care policy and international law.

A chorus of bells and other scientific inquiries

Bernstein, Jeremy
This book of essays in four parts, was written over a decade and full of surprises for the breadth and variety of its subject matter. The first part is about the foundations of the quantum theory which reflects the author's many conversations with the late John Bell who persuaded him that there is still no satisfactory interpretation of the theory. The second part deals with nuclear weapons. One of the essays concerns the creation of the modern gas centrifuge which was done by German prisoners of war in the Soviet Union. The proliferation of these centrifuges was one of the issues in the spread of nuclear weapons. The third section deals with financial engineering with a profile of Louis Bachelier, the French mathematician who created it at the beginning of the 20th century. The final section deals with the Higgs boson and how it is used for generating mass. It includes a detailed article of how this mechanism works.

The Jahn-Teller Effect and Vibronic Interactions in Modern Chemistry

Isaac Bersuker
The first half of the title of this book may delude the uninitiated reader. The term '"Jahn-Teller effect," taken literally, refers to a special effect inherent in particular molecular systems. Actually, this term implies a new approach to the general problem of correlations between the structure and properties of any molecular polyatomic system, including solids. Just such a new approach, or concept (in some sense, a new outlook or even a new way of thinking), which leads not to one special effect but to a series of different effects and laws, is embodied in the many ( ~ 4000) studies devoted to the investigation and application of the Jahn-Teller effect. The term "vibronic interactions" seems to be most appropriate to the new concept, and this explains the origin of the second half of the title. The primary objective of this book is to present a systematic develop ment of the concept of vibronic interactions and its applications, and to illustrate its possibilities and significance in modern chemistry. In the first three chapters (covering about one-third of the book) the theoretical background of the vibronic concept and Jahn-Teller effect is given. The basic ideas are illustrated fully, although a comprehensive presentation of the theory with all related mathematical deductions is beyond the scope of this book. In the last three chapters the applications of theory to spectro scopy, stereochemistry and crystal chemistry, reactivity, and catalysis, are illustrated by a series of effects and laws.

The Second Nuclear Era A New Start for Nuclear Power

Alvin Martin Weinberg
Nuclear energy is in a state of crisis in the United States. No new nuclear reactors have been ordered since 1978. The reason for this moratorium is that the safe operation of nuclear energy plants has been in doubt since the Three Mile Island crisis. The result of a study conducted by the Institute for Energy Analysis, this book examines the possibility of designing reactors that are completely safe--so safe that any rational arguments against the safety of nuclear power would no longer be valid.

Darwin's Audubon: science and the liberal imagination

Weissmann, Gerald
In this retrospective of Gerald Weissmann's best-known essays, the reader is treated to his unique perspective on what C. P. Snow once dubbed "the Two Cultures"-art and science. In Darwin's Audubon, Weissmann examines the powerful influence that the two exert over one another and how they have helped each other evolve. From listening to the scientists who gather ever year to sing at the Woods Hole Cantata Consort to looking at the influence of Audubon's watercolors on Darwin's On the Origin of Species; from comparing William Carlos Williams's poetry to his unedited case books to watching Oliver Wendell Holmes grow as doctor and as poet, Weissmann weaves a rich tapestry that will delight fans and newcomers alike.

Ivory Bridges Connecting Science and Society

Gerhard Sonnert,Gerald Holton
A study of two bridges between science and society: governmental science policy and scientists' voluntary public-interest associations. According to a widespread stereotype, scientists occupy an ivory tower, isolated from other parts of society. To some extent this is true, and the resulting freedom to pursue curiosity-driven research has made possible extraordinary scientific advances. The spinoffs of "pure" science, however, have also had powerful impacts on society, and the potential for future impacts is even greater. The public and many policymakers, as well as many researchers, have paid insufficient attention to the mechanisms for interchange between science and society that have developed since World War II. Ivory Bridges examines two such mechanisms: governmental science policy (often involving the participation of "scientist administrators") and scientists' voluntary public-interest associations. The examination of science policy is guided by the notion of "Jeffersonian science"---defined as basic research on topics identified as being in the national interest. The book illustrates the concept with a historical case study of the Press-Carter Initiative of the late 1970s and proposes that a Jeffersonian approach would make a valuable addition to future science policy. The book also looks at the activities of citizen-scientists who have organized themselves to promote the welfare of society. It shows that their numerous and diverse organizations have made major contributions to the commonweal and that they have helped to prevent science from becoming either too subservient to government or too autonomous. An extensive appendix profiles a wide variety of these organizations.
