Book Description
The field of cell biology is built on a foundation of discoveries stretching back to the earliest descriptions of cell theory in the 1800s. Today, our growing insight into cells and their control of life functions continues to generate advances in areas such as medicine, agriculture, genetics, and reproduction. This book traces the rise of cell biology and explains biological concepts through easy-to-follow text. Sidebars provide biographies of key scientists and descriptions of the evolution of microscopes and other significant technologies. Readers travel deep inside the cell, following the path of scientists as they unlock its mysteries.

Book Description
This fascinating new title examines the sequence of events that led to the formation of cell theory. In 1665, scientist Robert Hooke published Micrographia, the first significant work focused on miscroscopial observation. His groundbreaking work inspired scientists and led to the creation of this fundamental biological principle that shaped modern biology.

Book Description
More than a history, From Cells to Organisms delves into the nature of scientific practice, showing that results are interpreted not only through the lens of a microscope, but also through the lens of particular ideas and prior philosophical convictions. Before the twentieth century, heredity and development were considered complementary aspects of the fundamental problem of generation, but later they became distinct disciplines with the rise of genetics. Focusing on how cell theory shaped investigations of development, this book explores evolution, vitalism, the role of the nucleus, and the concept of biological individuality. Building upon the work of Thomas Huxley, an important early critic of cell theory, and more recent research from biologists such as Daniel Mazia, From Cells to Organisms covers ongoing debates around cell theory and uses case studies to examine the nature of scientific practice, the role of prestige, and the dynamics of theory change.

Book Description
Demand for fuel cell technology is growing rapidly. Fuel cells are being commercialized to provide power to buildings like hospitals and schools, to replace batteries in portable electronic devices, and as replacements for internal combustion engines in vehicles. PEM (Proton Exchange Membrane) fuel cells are lighter, smaller, and more efficient than other types of fuel cell. As a result, over 80% of fuel cells being produced today are PEM cells. This new edition of Dr. Barbir's groundbreaking book still lays the groundwork for engineers, technicians and students better than any other resource, covering fundamentals of design, electrochemistry, heat and mass transport, as well as providing the context of system design and applications. Yet it now also provides invaluable information on the latest advances in modeling, diagnostics, materials, and components, along with an updated chapter on the evolving applications areas wherein PEM cells are being deployed. Comprehensive guide covers all aspects of PEM fuel cells, from theory and fundamentals to practical applications Provides solutions to heat and water management problems engineers must face when designing and implementing PEM fuel cells in systems Hundreds of original illustrations, real-life engineering examples, and end-of-chapter problems help clarify, contextualize, and aid understanding

Book Description
During the past few decades we have witnessed an era of remarkable growth in the field of molecular biology. In 1950 very little was known ofthe chemical constitution of biological systems, the manner in which information was transmitted from one organism to another, or the extent to which the chemical basis oflife is unified. The picture today is dramatically different. We have an almost bewildering variety of information detailing many different aspects of life at the molecular level. These great advances have brought with them some breathtaking insights into the molecular mechanisms used by nature for replicating, distributing, and modifying biological information. We have learned a great deal about the chemical and physical nature of the macromo lecular nucleic acids and proteins, and the manner in which carbohydrates, lipids, and smaller molecules work together to provide the molecular setting ofliving systems. It might be said that these few decades have replaced a near vacuum of information with a very large surplus. It is in the context ofthis flood of information that this series of monographs on molecular biology has been organized. The idea is to bring together in one place, between the covers of one book, a concise assessment of the state of the subject in a well-defined field. This will enable the reader to get a sense of historical perspective-what is known about the field today-and a descrip tion of the frontiers of research where our knowledge is increasing steadily.

Book Description
"The difficulty of reconciling chemical mechanisms with the functions of whole living systems has plagued biologists since the development of cell theory in the nineteenth century. As Karl Matlin argues in Crossing the Boundaries of Life, it is no coincidence that this longstanding knot of scientific inquiry was loosened most meaningfully by the work of a cytologist, the Nobel laureate Günter Blobel. In 1975, using an experimental setup that did not contain any cells at all, Blobel was able to synthesize proteins to theorize how proteins in the cell communicate spatially, an idea he called signal hypothesis. Over the next 20 years, Blobel and other scientists were able to dissect this process into its precise molecular details. For elaborating his signal concept into a process he termed membrane topogenesis-the idea that each protein in the cell is synthesized with an "address" that directs the protein to its correct destination within the cell-Blobel was awarded the Nobel Prize in Physiology or Medicine in 1999. Matlin argues that Blobel's investigative strategy and its subsequent application addressed the fundamental unresolved dilemma that had bedeviled biology from its very beginning, allowing biology to overcome the barrier that had long blocked progress toward mechanistic explanations of life. Crossing the Boundaries of Life thus uses Blobel's research and life story to shed light on the importance of cell biology for twentieth-century science, illustrating how it propelled the development of adjacent disciplines like biochemistry and molecular biology"--
