This volume was, at the time of publication, the largest and most comprehensive book on the subject of cytology, a branch of zoology which had grown considerably in the years before 1924. It was written by the foremost cytologists in the United States, including Robert Chambers, Edwin G. Conklin, Edmund V. Cowdry, Merle H. Jacobs, Ernest E. Just, Margaret R. Lewis, Warren H. Lewis, Frank R. Lillie, Ralph S. Lillie, Clarence E. McClung, Albert P. Mathews, Thomas H. Morgan, and Edmund B. Wilson.
Aging and cancer may be manifestations of genetic, or epigenetic, changes in somatic cells. Through research, laboratory analysis of these related processes has become possible. Cells can be removed from the body, kept warm in laboratory glassware, nourished by artificial solutions, and studied for years, or even decades. Two types of cultures have emerged: Primary cultures, grown from cells obtained directly from living animals, may grow well for generations, but ultimately cease to divide. Established cultures, on the other hand, may grow and divide indefinitely. It is a striking fact that most, if not all, established cultures consist of cells that are heteroploid, having an abnormal chromosome complement that may include structural rearrangements as well as abnormalities of chromosome number.
Most established cultures are also neoplastic on behavior and morphology—in this, they resemble cancers—and established cultures are, in fact, often grown from cancer cells. Interest in the role of chromosomes in neoplasia has recently been overshadowed by an emphasis on tumor viruses. This book should reawaken the former interest. It will also arouse new interest in the role of epigenetic mechanisms of animal cells, in contrast to the classic genetic processes. As Dr. John Littlefield writes: “The relationship between the overcoming of senescence, the appearance of heteroploidy, and the acquisition of neoplastic qualities is not yet clear, but it is of such great theoretical and practical importance as to demand attention and new ideas.”
How did cells make the journey, one we take so much for granted, from their origin in living bodies to something that can be grown and manipulated on artificial media in the laboratory, a substantial biomass living outside a human body, plant, or animal? This is the question at the heart of Hannah Landecker's book. She shows how cell culture changed the way we think about such central questions of the human condition as individuality, hybridity, and even immortality and asks what it means that we can remove cells from the spatial and temporal constraints of the body and "harness them to human intention."
Rather than focus on single discrete biotechnologies and their stories--embryonic stem cells, transgenic animals--Landecker documents and explores the wider genre of technique behind artificial forms of cellular life. She traces the lab culture common to all those stories, asking where it came from and what it means to our understanding of life, technology, and the increasingly blurry boundary between them. The technical culture of cells has transformed the meaning of the term "biological," as life becomes disembodied, distributed widely in space and time. Once we have a more specific grasp on how altering biology changes what it is to be biological, Landecker argues, we may be more prepared to answer the social questions that biotechnology is raising.
Biological membranes have been under intensive investigation for several decades. Despite very great experimental challenges, membranes are at last beginning to reveal their secrets. In this book, leading investigators of membrane structure and function report on progress in three related fields: specialization of membrane regions, asymmetry in transport properties, and differentiation of cell faces in epithelia.
"Specialization at the Molecular Level" is the subject of the first section; in it, the authors consider such problems as the biogenesis of membranes, the geometry of protein-lipid relationships, and the physical properties of membrane receptor-sites. In the second section, "Asymmetry in Transport," such topics as the sodium-potassium pump, proton translocation, and anion transport are covered. The last section is entitled "Polar Faces in Epithelia" and deals with the complex properties of ion transport across the complex membrane environment maintained by surfaces such as the renal tubular epithelia.
Whether classified as regulators of inflammation, metabolism, or other physiological functions, a distinctive set of molecules enables the human body to convey information from one cell to another. An in-depth primer on the molecular mediators that coordinate complex bodily processes, Body Messages provides fresh insight into how biologists first identified this special class of molecules and the consequences of their discovery for modern medicine.
Focusing on proteins that regulate inflammation and metabolism—including the cytokines and adipokines at the core of her own research—Giamila Fantuzzi examines the role body messages play in the physiology of health as well as in the pathology of various illnesses. Readers are introduced to different ways of conceptualizing biomedical research and to the advantages and pitfalls associated with identifying molecules beginning with function or structure. By bringing together areas of research usually studied separately, Fantuzzi stresses the importance of investigating the body as a whole and affirms the futility of trying to separate basic from clinical research. Drawing on firsthand interviews with researchers who made major contributions to the field, Body Messages illustrates that the paths leading to scientific discovery are rarely direct, nor are they always the only routes available.
This synthesis of thirty-five years of intensive investigation comes at a particularly propitious moment. Since the Second World War, cell biology and molecular biology have worked separately in probing the central question of cancer research--how do cells divide?--biology focusing on cell behavior in isolation and as part of tissues and organs, molecular biology concentrating on individual biochemical steps, especially as controlled by genes. But now a new alliance is being forged in the continuing effort to conquer cancer. New discoveries point to the value of an interdisciplinary approach, and for the first time scientists from both camps are struggling to catch up on one another's literature.
Baserga's work provides the unifying background for this cross-fertilization of ideas. It begins with the growth of cell populations and how cells interact with each other. The second section goes within the cell to consider the effect of drugs, the use of temperature-sensitive mutants of the cell cycle, and the use of cell fusion to understand how cells divide. The third section turns to the molecular genetics of cell proliferation, the growth factors, and the genes and gene products that regulate cell division.
Drawing on more than five hundred classic and recent references, the book is comprehensive yet refreshingly readable. It will provide a congenial and sophisticated introduction for students as well as working scientists.
In the early 1960s, in a small shack on the Washington coast, a young, self-educated Japanese scientist performed an experiment to determine what made a certain jellyfish glow. The substance he discovered, green fluorescent protein, would revolutionize molecular biology, transforming our study of everything from the AIDS virus to the workings of the brain. Aglow in the Dark follows the path that took this glowing compound from its inauspicious arrival on the scientific scene to its present-day eminence as one of the most groundbreaking discoveries of the twentieth century.
The story unfolds in far-flung places, from the coral reefs of the Pacific Ocean, to the medical schools and marine stations of our leading universities, to a cold war-era research laboratory in Moscow. Traversing the globe and the decades, Aglow in the Dark conveys the human fascination with bioluminescence, or "living light," its little-known application in war, forensic science, and molecular biology, and how it led to the finding of green fluorescent protein. The book reveals a hidden world where light is manipulated by animals and humans and put to remarkable uses--unlocking the secrets of the human brain, conquering dreaded diseases, and perhaps someday linking minds and machines. The authors deftly lead the reader through a complex story at the interface of biology and physics--and into the realm of wonder on the frontiers of scientific endeavor.
Bioluminescence is everywhere on earth—most of all in the ocean, from angler fish in the depths to the flashing of dinoflagellates at the surface. Here, Thérèse Wilson and Woody Hastings explore the natural history, evolution, and biochemistry of the diverse array of organisms that emit light.
While some bacteria, mushrooms, and invertebrates, as well as fish, are bioluminescent, other vertebrates and plants are not. The sporadic distribution and paucity of luminous forms calls for explanation, as does the fact that unrelated groups evolved completely different biochemical pathways to luminescence. The authors explore the hypothesis that many different luciferase systems arose in the early evolution of life because of their ability to remove oxygen, which was toxic to life when it first appeared on earth. As oxygen became abundant and bioluminescence was no longer adequate for oxygen removal, other antioxidant mechanisms evolved and most luminous species became extinct. Those light-emitting species that avoided extinction evolved uses with survival value for the light itself. Today’s luminous organisms use bioluminescence for defense from predators, for their own predatory purposes, or for communication in sexual courtship.
Bioluminescence was earlier viewed as a fascinating feature of the living world, but one whose study seemed unlikely to contribute in any practical way. Today, bioluminescence is no longer an esoteric area of research. Applications are numerous, ranging from the rapid detection of microbial contamination in beef and water, to finding the location of cancer cells, to working out circuitry in the brain.

An essential companion, it presents 3,600 botanical terms, accompanied by full definitions and detailed illustrations to aid in identification, all laid out in a clear, easy-to-use fashion. It will be indispensable for plant scientists, conservationists, horticulturists, gardeners, writers, and anyone working with plant descriptions, plant identification keys, floras, or field guides.
This book brings together an international body of scholars working on eighteenth-century botany within the context of imperial expansion. The eighteenth century saw widespread exploration, a tremendous increase in the traffic in botanical specimens, taxonomic breakthroughs, and horticultural experimentation. The contributors to this volume compare the impact of new developments and discoveries across several regions, broadening the geographical scope of their inquiries to encompass imperial powers that did not have overseas colonial possessions—such as the Russian, Ottoman, and Qing empires and the Tokugawa shogunate—as well as politically borderline regions such as South Africa, Yemen, and New Zealand.
The essays in this volume examine the botanical ambitions of eighteenth-century empires; the figure of the botanical explorer; the links between imperial ambition and the impulse to survey, map, and collect botanical specimens in “new” territories; and the relationships among botanical knowledge, self-representation, and material culture.
Between 1777 and 1816, botanical expeditions crisscrossed the vast Spanish empire in an ambitious project to survey the flora of much of the Americas, the Caribbean, and the Philippines. While these voyages produced written texts and compiled collections of specimens, they dedicated an overwhelming proportion of their resources and energy to the creation of visual materials. European and American naturalists and artists collaborated to manufacture a staggering total of more than 12,000 botanical illustrations. Yet these images have remained largely overlooked—until now.
In this lavishly illustrated volume, Daniela Bleichmar gives this archive its due, finding in these botanical images a window into the worlds of Enlightenment science, visual culture, and empire. Through innovative interdisciplinary scholarship that bridges the histories of science, visual culture, and the Hispanic world, Bleichmar uses these images to trace two related histories: the little-known history of scientific expeditions in the Hispanic Enlightenment and the history of visual evidence in both science and administration in the early modern Spanish empire. As Bleichmar shows, in the Spanish empire visual epistemology operated not only in scientific contexts but also as part of an imperial apparatus that had a long-established tradition of deploying visual evidence for administrative purposes.
With masterful storytelling, Bergland and Hayes demonstrate how Lapham blended his ravenous curiosity with an equable temperament and a passion for detail to create a legacy that is still relevant today.
—John Gurda
In this long overdue tribute to Wisconsin’s first scientist, authors Martha Bergland and Paul G. Hayes explore the remarkable life and achievements of Increase Lapham (1811–1875). Lapham’s ability to observe, understand, and meticulously catalog the natural world marked all of his work, from his days as a teenage surveyor on the Erie Canal to his last great contribution as state geologist.
Self-taught, Lapham mastered botany, geology, archaeology, limnology, mineralogy, engineering, meteorology, and cartography. A prolific writer, his 1844 guide to the territory was the first book published in Wisconsin. Asked late in life which field of science was his specialty, he replied simply, “I am studying Wisconsin.”
Lapham identified and preserved thousands of botanical specimens. He surveyed and mapped Wisconsin’s effigy mounds. He was a force behind the creation of the National Weather Service, lobbying for a storm warning system to protect Great Lakes sailors. Told in compelling detail through Lapham’s letters, journals, books, and articles, Studying Wisconsin chronicles the life and times of Wisconsin’s pioneer citizen-scientist.
"Convincingly argues for the importance of these middle years to understanding American science and vividly illustrates the effect of the Civil War on science. . . . Ravenel, a geographically isolated planter with a college degree but no scientific training, managed to serve as one of America's leading mycologists, despite continual financial and medical problems and the disruption of the Civil War. This lively account of his life and work is at once inspiring and tragic."
Journal of the History of Biology
"A thoroughly enjoyable biography of one of the important American naturalists, botanists, and mycologists of the 1800s. . . . Truly an outstanding contribution to the history of American science."
—Brittonia
The first fruits of Greek botany.
Theophrastus of Eresus in Lesbos, born about 370 BC, is the author of the most important botanical works that have survived from classical antiquity. He was in turn student, collaborator, and successor of Aristotle. Like his predecessor he was interested in all aspects of human knowledge and experience, especially natural science. His writings on plants form a counterpart to Aristotle’s zoological works.
In the Enquiry into Plants Theophrastus classifies and describes varieties—covering trees, plants of particular regions, shrubs, herbaceous plants, and cereals; in the last of the nine books he focuses on plant juices and medicinal properties of herbs. This edition is in two volumes; the second contains two additional treatises, On Odours and Weather Signs.
In De causis plantarum Theophrastus turns to plant physiology. Books 1 and 2 are concerned with generation, sprouting, flowering and fruiting, and the effects of climate. In Books 3 and 4 Theophrastus studies cultivation and agricultural methods. In Books 5 and 6 he discusses plant breeding; diseases and other causes of death; and distinctive flavors and odors. The Loeb Classical Library edition is in three volumes.
Theophrastus’ celebrated Characters is of a quite different nature. This collection of descriptive sketches is the earliest known character-writing and a striking reflection of contemporary life.
