Do you often lose your keys? You will find in this book the best strategy to find them, or at least the one deduced from statistical physics. What is the link with biology? Some proteins use the same strategy to find their target inside a living cell. This example illustrates one of the many links between physics and biology. These links result from an intense research activity in the past years at the interface between those two disciplines. This book describes some of the most recent progresses at this interface: from instrumental progresses used in biology to the mechanical description of a cell, to molecular motors, from brain activity mechanisms to auditory or sensory perception. Many fields are covered from the molecular to the scale at the organ level. A few biological notions are presented in the first chapter that may help to access the biological aspects of the others. In the end this book may interest people passionate in science, from the simple amateur to the advanced researcher level. Contents:Some Biology Basic PrinciplesFluorescence Microscopy for Biological ImagingMechanical Studies on Single Molecules: General ConsiderationsMolecular MotorsCellular Mechanics and MotilityExploring Neuronal Activity with PhotonsPhysical Principles of HearingSensing Through Friction: The Biomechanics of Texture Perception in Rodents and PrimatesIntermittent Search Strategies Readership: Advanced undergraduates and graduate or any person with a strong scientific background interested by the physics/biology interface. Key Features:No book treating these very different aspects of biophysics is on the market. Some aspects are not treated in any book. It is more introductory and less technical than competing books on similar subjectsKeywords:Biophysics;Molecular Motors;Single Molecule Mechanics;Cellular Mechanics;Physics of Hearing;Neuronal Activity;Microscopy;Biomechanics of Texture;Search Strategies in Biology

The book gathers lecture notes of courses given at the 2014 summer school on integrated biology in Les Houches, France, Session CII. It addresses an emerging field ranging from molecules to cells and to organisms. Through examples it presents a new way of thinking using a combination of interdisciplinary and cutting-edge methods, bridging physics and biology beyond current biophysics. Important novel developments are expected in the coming years that may well introduce paradigm shifts in biological science. The school had the ambition to prepare participants to become major actors in these breakthroughs. The power of integrated approaches is illustrated through two cases: interactions between viruses and host cells, and flower development. The role of forces in biology, as well as their mathematical modeling, is illustrated in both processes: how they allow flower organs to emerge or how they control membrane fusion during virus budding. The book also underlines the importance of conformational changes and dynamics of proteins particularly during membrane processes. It explains how membrane proteins can be handled and studied by molecular simulations. Finally, the book also contains concepts in cell biology, in thermodynamics and several novel approaches such as in-cell NMR. Altogether, the chapters show how examining a biological system from different viewpoints based on multidisciplinary aspects often leads to enriching controversial arguments.

Aimed at those working to enter this rapidly developing field, this volume on biological physics is written in a pedagogical style by leading scientists giving explanations that take their starting point where any physicist can follow and end at the frontier of research in biological physics. These lectures describe the state-of-the-art physics of biomolecules and cells. In biological systems ranging from single biomolecules to entire cells and larger biological systems, it focuses on aspects that require concepts and methods from physics for their analysis and understanding, such as the mechanics of motor proteins; how the genetic code is physically read and managed; the machinery of protein--DNA interactions; force spectroscopy of biomolecules' velopes, cytoskeletons, and cytoplasms; polymerization forces; listeria propulsion; cell motility; lab-on-a-chip nanotechnology for single-molecule analysis of biomolecules; bioinformatics; and coding and computational strategies of the brain.

Molecular Biophysics presents the fundamental principles of biophysics and their application to the study of the physical properties of biological macromolecules. The merger of biology and physics involves the development of sophisticated instrumentation and the molecular approach to the study of life phenomena. This book is composed of nine chapters and begins with an overview of the thermodynamical aspects and chemical foundations of biophysics. These topics are followed by the physical aspects of macromolecules, with a particular emphasis on the biological functions, conformation, and hydrophobic interactions of proteins. The subsequent chapter describes the structural and electro-optical properties of biopolymers based on X-ray, optical, and spectroscopic analysis. The discussion then shifts to enzymes, their chemical kinetics, catalytic potential, and conformational and cooperative properties. The remaining chapters explore the physical aspects of nucleic acids and the biosynthesis of proteins. This book will prove useful to molecular biophysicists, biologists, physicists, and researchers in the fields of life sciences.

acids. The achievements of molecular biology testify to the success of material science in a realm which, until recently, appeared totally enig matic and mysterious. Further scientific developments should bring to mankind vast developments both in theoretical knowledge and in practical applications, namely, in agriculture, medicine, and technology. The purpose of this book is to explain molecular biophysics to all who might wish to learn about it, to biologists, to physicists, to chemists. This book contains descriptive sections, as well as sections devoted to rigorous mathematical treatment ofa number of problems, some of which have been studied by the author and his collaborators. These sections may be omitted during a first reading. Each chapter has a selected bibliography. This book is far from an exhaustive treatise on molecular biophysics. It deals principally with questions related to the structures and functions of proteins and nucleic acids. M. V.
