This book is authored by an exciting mixture of top experts and young rising stars from the fields of molecular chaperones and stress adaptation. In addition to giving a comprehensive summary with original references to their field, all authors share their hypotheses and vision on future trends with the reader. The book makes a novel synthesis of the molecular aspects of the stress response and long term adaptation processes with the system biology approach of biological networks. A novel perspective of "old facts" is provided in each chapter, where "old" means only 5-10 years in this rapidly expanding field.
