DOWNLOAD EBOOKThis book introduces a fresh perspective on the conditions for the genesis of the first cell. An important possible environment of the prehistoric Earth has long been overlooked as a host to the perfect biochemical conditions for this process. The first complexes of continental crust on the early Earth must have already contained systems of interconnected cracks and cavities, which were filled with volatiles like water, carbon dioxide and nitrogen. This book offers insights into how these conditions may have provided the ideal physical and chemical setting for the formation of protocells and early stages of life. The authors support their hypothesis with a number of astonishing findings from laboratory experiments focusing on a variety of organic compounds, and on the formation of key cellular ingredients and of primitive cell-like structures. Moreover, they discuss the principles of prebiotic evolution regarding the aspects of order and complexity. Guiding readers through various stages of hypotheses and re-created evolutionary processes, the book is enriched with personal remarks and experiences throughout, reflecting the authors' personal quest to solve the mystery surrounding the first cell.

DOWNLOAD EBOOKThis comprehensive history of cell evolution “deftly discusses the definition of life” as well as cellular organization, classification and more (San Francisco Book Review). The origin of cells remains one of the most fundamental mysteries in biology, one that has spawned a large body of research and debate over the past two decades. With In Search of Cell History, Franklin M. Harold offers a comprehensive, impartial take on that research and the controversies that keep the field in turmoil. Written in accessible language and complemented by a glossary for easy reference, this book examines the relationship between cells and genes; the central role of bioenergetics in the origin of life; the status of the universal tree of life with its three stems and viral outliers; and the controversies surrounding the last universal common ancestor. Harold also discusses the evolution of cellular organization, the origin of complex cells, and the incorporation of symbiotic organelles. In Search of Cell History shows us just how far we have come in understanding cell evolution—and the evolution of life in general—and how far we still have to go. “Wonderful…A loving distillation of connections within the incredible diversity of life in the biosphere, framing one of biology’s most important remaining questions: how did life begin?”—Nature

DOWNLOAD EBOOKA majority of evolutionary biologists believe that we now can envision our biological predecessors--not the first, but nearly the first, living beings on Earth. This book is about these vanished forebears. The era between the first rudimentary life on Earth and the appearance of more complex beings is called the RNA world. It is RNA (ribonucleic acid) long believed to be a mere biologic copier and messenger, that offers a glimpse into our ancient predecessors. To describe early RNA creatures, here called "ribocytes" or RNA cells, the author uses basics of molecular biology. He reviews our current understanding of the tree of life, examines the structure of RNA itself, explains the operation of the genetic code, and more. Courting controversy among those who question the role of ribocytes -- citing the chemical fragility of RNA and the uncertainty about the origin of an RNA synthetic apparatus -- he offers a vision of early life on Earth.

DOWNLOAD EBOOKStem cells are relatively undifferentiated cells which are the permanent lineage ancestor cells of tissues. Newly developed molecular biological techniques and probes have made possible dramatic advances in our ability to study the lineage development of stem cells. A major impetus to develop these techniques has been to identify specific stem cells for gene therapy purposes. The role that stem cells play in the development of cancer is also an important area. This book provides up-to-date reviews on a wide variety of stem cell systems by world experts. Chapters range from descriptions of the current knowledge of the biology of stem cells, to current molecular biological approaches and clinical implications. Oncologists and cell biologists will find this book of particular interest. It will also be usefule to radiobiologist, biotechnologists, and gene therapists. Provides reviews of stem cell systems by world experts Covers stem cell biology in plants, invertebrates, and mammals Presents clinical implications of stem cell differentiation

DOWNLOAD EBOOKThe searing conclusion of the thrilling epic fantasy trilogy that saw a young girl trained by an arcane order of nuns grow into the fiercest of warriors... They came against her as a child. Now they face the woman. The ice is advancing, the Corridor narrowing, and the empire is under siege from the Scithrowl in the east and the Durns in the west. Everywhere, the emperor’s armies are in retreat. Nona Grey faces the final challenges that must be overcome if she is to become a full sister in the order of her choice. But it seems unlikely that she and her friends will have time to earn a nun’s habit before war is on their doorstep. Even a warrior like Nona cannot hope to turn the tide of war. The shiphearts offer strength that she might use to protect those she loves, but it’s a power that corrupts. A final battle is coming in which she will be torn between friends, unable to save them all. A battle in which her own demons will try to unmake her. A battle in which hearts will be broken, lovers lost, thrones burned.

DOWNLOAD EBOOK“Handsome and elegantly designed, this tour through the cell’s history and diversity in form and function is a delight to peruse . . . stunning.” —American Scientist With The Cell, Jack Challoner treats readers to a visually striking tour of these remarkable molecular machines. Most of the living things we’re familiar with—the plants in our gardens, the animals we eat—are composed of billions or trillions of cells. Most multicellular organisms consist of many different types of cells, each highly specialized to play a particular role—from building bones or producing the pigment in flower petals to fighting disease or sensing environmental cues. But the great majority of living things on our planet exist as single cell. These cellular singletons are every bit as successful and diverse as multicellular organisms, and our very existence relies on them. The book is an authoritative yet accessible account of what goes on inside every living cell—from building proteins and producing energy to making identical copies of themselves—and the importance of these chemical reactions both on the familiar everyday scale and on the global scale. Along the way, Challoner sheds light on many of the most intriguing questions guiding current scientific research: What special properties make stem cells so promising in the treatment of injury and disease? How and when did single-celled organisms first come together to form multicellular ones? And how might scientists soon be prepared to build on the basic principles of cell biology to build similar living cells from scratch? “Small really is beautiful: Psychedelic images show the inner workings of cells in stunning detail.” —Daily Mail
