In an intriguing series of experiments carried out many years ago, a common scientific belief, feted by no less than three Nobel prizes, was brought into question. The observations were about proteins—the molecules that the genetic code specifies and that are in one way or another central to all of life’s activities. The experiments however were not about what proteins do, but how they are moved, in particular how they are moved from where they are made to where they act. The results of these studies conflicted with the standard view of how this happens, and thus became controversial. The standard view, the vesicle theory of protein secretion, envisions proteins being carried within and out of cells en masse in membrane-bound sacs or vesicles. The controversial experiments demonstrated that to the contrary individual protein molecules cross the relevant membranes as a result of their own motion. This was thought to be impossible at the time. Proteins Crossing Membranes is a personal narrative that tells the story of the controversy. Among other things, the author illustrates that scientists, like the rest of us, can rigidly hold onto their beliefs despite evidence that they are misguided. Key Features Reviews the data in support and critical of the vesicle theory of protein secretion Explores the ways scientists respond to evidence that challenges a favored theory Documents the author’s personal experiences in this conflict-laden situation

As part of a unique series covering the grand sweep of Western civilization from ancient to present times, this biographical dictionary provides introductory information on 315 leading cultural figures of late medieval and early modern Europe. Taking a cultural approach not typically found in general biographical dictionaries, the work includes literary, philosophical, artistic, military, religious, humanistic, musical, economic, and exploratory figures. Political figures are included only if they patronized the arts, and coverage focuses on their cultural impact. Figures from western European countries, such as Italy, France, England, Iberia, the Low Countries, and the Holy Roman Empire predominate, but outlying areas such as Scotland, Scandinavia, and Eastern Europe are also represented. Late medieval Europe was an age of crisis. With the Papacy removed to Avignon, the schism in the Catholic Church shook the very core of medieval belief. The Hundred Years' War devastated France. The Black Death decimated the population. Yet out of this crisis grew an age of renewal, leading to the Renaissance. The great Italian city-states developed. Humanism reawakened interest in the cultures of ancient Greece and Rome. Dante and Boccaccio began writing in their Tuscan vernacular. Italian artists became humanists and flourished. As the genius of Italy began spreading to northern and western Europe at the end of the 15th century, the age of renewal was completed. This book provides thorough basic information on the major cultural figures of this tumultuous era of crisis and renewal.
