Popular science at its most exciting: the breaking new world of chronobiology - understanding the rhythm of life in humans and all plants and animals. The entire natural world is full of rhythms. The early bird catches the worm -and migrates to an internal calendar. Dormice hibernate away the winter. Plants open and close their flowers at the same hour each day. Bees search out nectar-rich flowers day after day. There are cicadas that can breed for only two weeks every 17 years. And in humans: why are people who work anti-social shifts more illness prone and die younger? What is jet-lag and can anything help? Why do teenagers refuse to get up in the morning, and are the rest of us really 'larks' or 'owls'? Why are most people born (and die) between 3am-5am? And should patients be given medicines (and operations) at set times of day, because the body reacts so differently in the morning, evening and at night? The answers lie in our biological clocks the mechanisms which give order to all living things. They impose a structure that enables us to change our behaviour in relation to the time of day, month or year. They are reset at sunrise and sunset each day to link astronomical time with an organism's internal time.

An introduction to the mathematical, computational, and analytical techniques used for modeling biological rhythms, presenting tools from many disciplines and example applications. All areas of biology and medicine contain rhythms, and these behaviors are best understood through mathematical tools and techniques. This book offers a survey of mathematical, computational, and analytical techniques used for modeling biological rhythms, gathering these methods for the first time in one volume. Drawing on material from such disciplines as mathematical biology, nonlinear dynamics, physics, statistics, and engineering, it presents practical advice and techniques for studying biological rhythms, with a common language. The chapters proceed with increasing mathematical abstraction. Part I, on models, highlights the implicit assumptions and common pitfalls of modeling, and is accessible to readers with basic knowledge of differential equations and linear algebra. Part II, on behaviors, focuses on simpler models, describing common properties of biological rhythms that range from the firing properties of squid giant axon to human circadian rhythms. Part III, on mathematical techniques, guides readers who have specific models or goals in mind. Sections on “frontiers” present the latest research; “theory” sections present interesting mathematical results using more accessible approaches than can be found elsewhere. Each chapter offers exercises. Commented MATLAB code is provided to help readers get practical experience. The book, by an expert in the field, can be used as a textbook for undergraduate courses in mathematical biology or graduate courses in modeling biological rhythms and as a reference for researchers.

This book is a concise, comprehensive and up-to-date account of fundamental concepts and potential applications of biological timekeeping mechanisms in animals and humans. It also discusses significant aspects of the organization and importance of timekeeping mechanisms in both groups. Divided into seven sections, it addresses important aspects including fundamental concepts; animal and human clocks; clock interactions; clocks and metabolism and immune functions; pineal, melatonin and timekeeping; and clocks, photoperiodism and seasonal behaviours. The book also focuses on biological clock applications in a 24x7 human society, particularly in connection with life-style associated disorders like obesity and diabetes. It is a valuable resource for advanced undergraduates, researchers and professionals engaged in the study of the science of biological timekeeping.

This book sheds new light on the molecular mechanisms that generate circadian rhythms. It examines how biological rhythms influence physiological processes such as sleep, hormone synthesis and secretion, immunity, kidney function, the cardiovascular system, blood pressure, and the digestive system. Clinical implications are considered while exploring the impact of rhythms on neuropsychiatric disorders and chronotherapy’s potential for reducing cardiovascular risk. Offering a cross-section of expertise in both basic and translational (bench-to-bedside) research, this book serves as a guide for physicians and scientists who wish to learn more about the impact of circadian rhythms on physiological processes in health and disease.

Our body's clocks make the difference between happiness and depression, health and illness, and even life and death. The brilliant scientist Paul Kelley makes a compelling case for all organisations to allow people to work and study the hours that suit their personal circadian rhythms. That way, Paul argues, we would all be more productive, a great deal of ill health would be avoided and the world would be a better and happier place.

Each organism has its own internal biological clock, which is reset by environmental cues (Zeitgebers), thus keeping it synchronized with the external environment. It is a chemically based oscillating system within cells, relying on molecular feedback loops. Circadian biological clocks exist in most organisms.What is so special about the clock in f

Dr. Harry Fisch, a leading expert in male infertility, shares groundbreaking information about the bodily and behavioral changes that happen over the course of a man’s lifetime. Busting the myth that men don’t have biological clocks, Dr. Henry Fisch emphasizes that even young men can have testosterone levels as low as those of much older men, leading to infertility, sexual problems, and other serious health issues. Every couple should know all the risks and issues facing men, because these affect two of the most important things in their life: their ability to have children and their capacity to have good sex. The Male Biological Clock is a must read for every man and every couple who is struggling to have children or improve their sex life. Many of Dr. Harry Fisch's findings are startling—beginning with the fact that infertility is not mostly a women's problem—and he offers many helpful suggestions for how to deal with declining testosterone, changing sexual needs, and the fertility industry. The Male Biological Clock tells you what you need to know and how you can achieve optimal fertility and sexuality.
