Dynamics and the Problem of Recognition in Biological Macromolecules
From within complex structures of organisms and cells down to the molecular level, biological processes all involve movement. Muscular fibers slide on each other to activate the muscle, as polymerases do along nucleic acids for replicating and transcribing the genetic material. Cells move and organize themselves into organs by recognizing each other through macromolecular surface-specific interactions. These recognition processes involve the mu tual adaptation of structures that rely on their flexibility. All sorts of conformational changes occur in proteins involved in through-membrane signal transmission, showing another aspect of the flexibility of these macromolecules. The movement and f...
Seeking the First Farmers in Western Sjælland, Denmark
This volume summarizes 30 years of fieldwork in Denmark, some of the evidence for the spread of agriculture and the Neolithic into Scandinavia and some opinions about the origins of agriculture. It is intended to be both academic and personal and to describe the actual process of research, because most projects involve elements of both. There is an introduction to each chapter that relates some of the more personal aspects of the research and the bulk of each chapter will be a more technical scientific report on our investigations. Each chapter will deal with one of the components of the project - survey, testing and excavations. We excavated eight sites from the Late Mesolithic and Early Neolithic that are discussed in this volume. The concluding chapter summarizes our research in the area and proffers opinions on a variety of archaeological subjects, with visits to climate change, seasonality and sedentism, hunter-gatherer complexity, aDNA, inequality and the origins and spread of agriculture.
