Book Description
This book uses the history of cell theory to explore the emergence of biology as a distinct field in its own right--separate from anatomy, physiology, and natural history. It also explores nineteenth- and twentieth-century ideas about heredity and development and the progress that was made at the turn of the century when they began to be studied on their own--leading to new understandings of a variety of biological problems, from evolution to cancer. Investigating this story will help readers gain an appreciation of the historical development of scientific ideas. It beautifully illustrates that the process of science is not as straightforward as it is usually portrayed. One of the important lessons of this intriguing story is that "facts" do not necessarily speak for themselves, and observations always need to be interpreted.

Book Description
A Physarum machine is a programmable amorphous biological computer experimentally implemented in the vegetative state of true slime mould Physarum polycephalum. It comprises an amorphous yellowish mass with networks of protoplasmic veins, programmed by spatial configurations of attracting and repelling gradients. This book demonstrates how to create experimental Physarum machines for computational geometry and optimization, distributed manipulation and transportation, and general-purpose computation. Being very cheap to make and easy to maintain, the machine also functions on a wide range of substrates and in a broad scope of environmental conditions. As such a Physarum machine is a 'green' and environmentally friendly unconventional computer. The book is readily accessible to a nonprofessional reader, and is a priceless source of experimental tips and inventive theoretical ideas for anyone who is inspired by novel and emerging non-silicon computers and robots.

Book Description
Cell to Cell Signalling: From Experiments to Theoretical Models is a collection of papers from a NATO Workshop conducted in Belgium in September 1988. The book discusses nerve cells and neural networks involved in signal transfers. The works of Hodgkin and Huxley presents a prototypic combination between experimental and theoretical approaches. The book discusses the coupling process found between secretory cells that modify their behavior. The text also analyzes morphogenesis and development, and then emphasizes the pattern formation found in Drosophila and in the amphibian embryo. The text also cite examples of immunological modeling that is related to the dynamics of immune networks based on idiotypic regulation. One paper analyzes the immune dynamism of HIV infection. The text notes that hormone signaling can be attributed as responsible for intercellular communication. Another paper examines how the dominant follicle in the ovarian cycle is selected, as well as the effectiveness of hormone secretion responsible for encoding the frequency of occurrence of periodic signals. The book also discusses heart signal sources such as cardiac dynamics and the response of periodically excited cardiac cells. The text can prove valuable for practioners in the field of neurology and cardiovascular medicine, and for researchers in molecular biology and molecular chemistry.

Book Description
As 1 review these pages, the last of them written in Summer 1978, some retrospec tive thoughts come to mind which put the whole business into better perspective for me and might aid the prospective reader in choosing how to approach this volume. The most conspicuous thought in my mind at present is the diversity of wholly independent explorations that came upon phase singularities, in one guise or another, during the past decade. My efforts to gather the published literature during the last phases of actually writing a whole book about them were almost equally divided between libraries of Biology, Chemistry, Engineering, Mathematics, Medicine, and Physics. A lot of what 1 call "gathering " was done somewhat in anticipation in the form of cönjecture, query, and prediction based on analogy between developments in different fields. The consequence throughout 1979 was that our long-suffering publisher re peatedly had to replace such material by citation of unexpected flurries of papers giving substantive demonstration. 1 trust that the authors of these many excellent reports, and especially of those I only found too late, will forgive the brevity of allusion I feIt compelled to observe in these substitutions. A residue of loose ends is largely collected in the index under "QUERIES. " It is c1ear to me already that the materials I began to gather several years ago represented only the first flickering of what turns out to be a substantial conflagration.

Book Description
This densely-packed book introduces the fascinating world of myxomycetes, the acellular slime moulds. It describes their intriguing life cycle and important ecological roles as decomposers, nutrient recyclers and food for numerous invertebrates. And it reveals their exquisite evocative forms through microscope and camera, along with time lapse images that capture the dramatic changes in colour and shape as the fruiting bodies mature.The past ten years has seen a burgeoning interest in slime moulds by photographers, students and enthusiasts who are captivated by their singular beauty. This popular and informative book-now in its fourth edition-is an aid to their identification, an illustrated glossary, and an account of a passion for slime moulds that has led to the discovery of a wealth of species inhabiting a tall wet eucalypt forest in central north Tasmania.

Book Description
Kenneth Raper tells how dictyostelids are isolated, cultivated, and conserved in the laboratory; how myxamoebae aggregate to form multicellular pseudoplasmodia; how fructifications arise by transformation of amoeboid cells into stalk cells and spores; and how similar cells can, under certain conditions, enter a sexual phase. For each known dictyostelid Professor Raper includes a complete description and photographic illustrations; one new species is described. Originally published in 1984. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Book Description
Since their discovery in 1869, the dictyostelids have attracted the attention of scientists in a wide variety of fields. This interest has stemmed from their peculiar lifestyle and developmental properties, which were shaped by the evolutionary forces that generated multicellularity during eukaryotic evolution. More recently, the dictyostelids have gained attention due to the striking similarities found at the genomic, cellular and biochemical levels with human cells, which has propelled the species Dictyostelium discoideum to become a model system for biology and medicine in many laboratories. This book covers the latest advances in our knowledge of these extraordinary organisms with topics spanning from their evolutionary history, ecology and diversity to the recent discoveries regarding their cellular and molecular biology.
