Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The Biological Clock describes the rhythmic processes in a great variety of plants and animals. This book is an outgrowth of the 1969 James Arthur Lecture Series on "Time and its Mysteries" held at New York University. This three-chapter work begins with the basic principles of biological rhythms and clocks, along with various diagrams to illustrate some aspects of circadian rhythms in animals. The second chapter discusses the hypothesis of environmental timing of the clock. This chapter explores numerous research studies on phenomenon of biological rhythms, the nature of the rhythmic mechanism, and hormonal regulation. The third chapter examines the cellular-biochemical clock hypothesis and its contribution in the progress of understanding the complexity of biological rhythm. This book is intended primarily for biologists, behaviorists, and researchers.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: "A clock," writes Arthur T. Winfree, "is not much good if you can't pull out its stem and set it." Similarly, the most critical property of biological clocks--which rhythmically organize the processes of life--is their ability to reset on cue. This ability allows enables biological clocks to regain synchrony with a changing environment (as when we travel across time zones) or to maintain the alignment between certain physiological rhythms and the natural solar day. In The Timing of Biological Clocks, Winfree explores circadian rhythms. In reporting experiments on animals, plants, and single cells, he not only illustrates the principles that guide the resetting of biological clocks but reveals that each of these clocks has a vulnerable phase, a moment in each "turn of the dial" when a cueing stimulus of a particular intensity results in an abnormal, unpredictable resetting--perhaps even annihilating the clock's rhythm entirely. A singular feature of the author's exploration of these phenomena is his use of a range of colors to represent the passage of cyclic time. By this device, Winfree not only removes the purely arbitrary discontinuity of a conventional clock dial but makes reasoning about the real discontinuities of biological clocks transparently clear.

Available in PDF, EPUB and Kindle. Book excerpt: 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 fish? Where is it located—in the retina, inside the brain, or in the pineal? What is the molecular basis of its function? How is the clock able to keep time in the absence of environmental cues? Although biological clocks have been intensively studied over the past four decades, only recently have the tools needed to examine the molecular basis of circadian rhythms become available. This book reviews the state of knowledge in sufficient detail and presents the latest contributions to the field, showing fish provide a unique model of the circadian biological clock.

Book excerpt: Insect Clocks is mainly concerned with the phenomena in which ""environmental time"" has a practical implication for the life of insects for them to perform behavioral or physiological episodes at the ""right time"" and season. This text first discusses the concept of rhythms and clocks, along with the seasonal changes in the environment that affect a particular group of organisms. This book then explains circadian rhythms of insects. Photoperiodism and seasonal cycles of development; photoperiodic response, clock, and counter; and other types of insect clock are also tackled. This text concludes by explaining the anatomical location of photoreceptors and clocks. This publication will be invaluable to those interested in studying insects and their development affected by circles of influences.

Book excerpt: A candid assessment of the pros and cons of delayed motherhood. Biology does not bend to feminist ideals and science does not work miracles. That is the message of this eye-opening discussion of the consequences of delayed motherhood. Part personal account, part manifesto, Selvaratnam recounts her emotional journey through multiple miscarriages after the age of 37. Her doctor told her she still "had time," but Selvaratnam found little reliable and often conflicting information about a mature woman's biological ability (or inability) to conceive. Beyond her personal story, the author speaks to women in similar situations around the country, as well as fertility doctors, adoption counselors, reproductive health professionals, celebrities, feminists, journalists, and sociologists. Through in-depth reporting and her own experience, Selvaratnam urges more widespread education and open discussion about delayed motherhood in the hope that long-lasting solutions can take effect. The result is a book full of valuable information that will enable women to make smarter choices about their reproductive futures and to strike a more realistic balance between science, society and personal goals.

Available in PDF, EPUB and Kindle. Book excerpt: Environmental conditions change considerably in the course of 24 h with respect to abiotic factors and intra- and interspecific interactions. These changes result in limited time windows of opportunity for animal activities and, hence, the question of when to do what is subject to fitness maximisation. This volume gives a current overview of theoretical considerations and empirical findings of activity patterns in small mammals, a group in which the energetic and ecological constraints are particularly severe and the diversity of activity patterns is particularly high. Following a comparative ecological approach, for the first time activity timing is consequently treated in terms of behavioural and evolutionary ecology, providing the conceptual framework for chronoecology as a new subdiscipline within behavioural ecology. An extensive Appendix gives an introduction to methods of activity modelling and to tools for statistical pattern analysis.

Book excerpt: Packed with science-based insight into what it really means to 'age' and reminding us that we have far more control over how young we feel and look than most of us realize, this comprehensive guide, by natural health expert Jayney Goddard, offers the ultimate blueprint for anti-ageing the natural way. Our attitudes towards ageing have undergone radical changes in recent years and many women now recognize that beauty and health come not from invasive procedures, fillers or expensive skincare brands but from the inside out. This book is an expert holistic guide on the science of how to age well - not only physically and mentally but also emotionally and even spiritually - covering everything from nutrition, herbal medicine, good breathing, the best exercise, mental attitude, natural skincare, haircare and facelift techniques, hormonal balance, good relationships, the power of nature and the power of sleep. Each chapter includes easily implementable techniques which, while natural, are supported by solid scientific research, with a focus on the neurobiology of happiness and how to develop a 'rewind' mindset. All this is underpinned with biological age tests for readers to try for themselves and, at the end, a specifically designed practical programme called the 'Personal 21-Day Rewind Plan'. The result? Better skin, a leaner body, stronger bones, improved cognitive function, enhanced libido, more energy, improved immune function, increased resistance to degenerative diseases, more resilience against stress and much more. So, while we can't change our chronological age, we can dramatically reduce and even reverse our biological age so that we have plenty more healthy, happy years to look forward to.
