Book excerpt: As 1 review these pages, the last of them written in Summer 1978, some retrospec tive thoughts come to mind which put the whole business into better perspective for me and might aid the prospective reader in choosing how to approach this volume. The most conspicuous thought in my mind at present is the diversity of wholly independent explorations that came upon phase singularities, in one guise or another, during the past decade. My efforts to gather the published literature during the last phases of actually writing a whole book about them were almost equally divided between libraries of Biology, Chemistry, Engineering, Mathematics, Medicine, and Physics. A lot of what 1 call "gathering " was done somewhat in anticipation in the form of cönjecture, query, and prediction based on analogy between developments in different fields. The consequence throughout 1979 was that our long-suffering publisher re peatedly had to replace such material by citation of unexpected flurries of papers giving substantive demonstration. 1 trust that the authors of these many excellent reports, and especially of those I only found too late, will forgive the brevity of allusion I feIt compelled to observe in these substitutions. A residue of loose ends is largely collected in the index under "QUERIES. " It is c1ear to me already that the materials I began to gather several years ago represented only the first flickering of what turns out to be a substantial conflagration.

Book excerpt: Biological Time Is For The Naturalist, Scientist, Outdoors Person, Gardener And All Those Who Wonder What Clocks Nature Follows. Plants And Animals Time Themselves By Rhythms Of Light And Darkness. We Often Think Of The Sun And How It Transforms The Seasons, But Illumination From The Moon Governs The Night And Presents Equally Important Influences. Prehistoric People Understood These Relationships And Used Their Movements To Mark Time And Plan For Important Events, Such As When To Hunt, Fish And Gather Wild Fruits. Farmers Utilized This Same Formula To Forecast The Success Of Crops And Animals.Great Civilizations Were Built And Religions Formed Based On This Methodology, Which Is Still Practiced By Some Indigenous Peoples. Biological Time Presents An Extraordinary Hypothesis, Supported With Archeological Evidence And A Wide Range Of Examples Ranging From Salmon, Deer, And Geese To Grapes.This Special Low-Priced Edition Is For Sale In India, Bangladesh, Bhutan, Maldives, Nepal, Myanmar, Pakistan And Sri Lanka Only.

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: This authored monograph introduces a genuinely theoretical approach to biology. Starting point is the investigation of empirical biological scaling including their variability, which is found in the literature, e.g. allometric relationships, fractals, etc. The book then analyzes two different aspects of biological time: first, a supplementary temporal dimension to accommodate proper biological rhythms; secondly, the concepts of protension and retention as a means of local organization of time in living organisms. Moreover, the book investigates the role of symmetry in biology, in view of its ubiquitous importance in physics. In relation with the notion of extended critical transitions, the book proposes that organisms and their evolution can be characterized by continued symmetry changes, which accounts for the irreducibility of their historicity and variability. The authors also introduce the concept of anti-entropy as a measure for the potential of variability, being equally understood as alterations in symmetry. By this, the book provides a mathematical account of Gould's analysis of phenotypic complexity with respect to biological evolution. The target audience primarily comprises researchers interested in new theoretical approaches to biology, from physical, biological or philosophical backgrounds, but the book may also be beneficial for graduate students who want to enter this field.

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: In many biological models it is necessary to allow the rates of change of the variables to depend on the past history, rather than only the current values, of the variables. The models may require discrete lags, with the use of delay-differential equations, or distributed lags, with the use of integro-differential equations. In these lecture notes I discuss the reasons for including lags, especially distributed lags, in biological models. These reasons may be inherent in the system studied, or may be the result of simplifying assumptions made in the model used. I examine some of the techniques available for studying the solution of the equations. A large proportion of the material presented relates to a special method that can be applied to a particular class of distributed lags. This method uses an extended set of ordinary differential equations. I examine the local stability of equilibrium points, and the existence and frequency of periodic solutions. I discuss the qualitative effects of lags, and how these differ according to the choice of discrete or distributed lag. The models studied are drawn from the population dynamiCS of single species (logistic growth, the chemostat) and of interacting pairs of species (predation, mutualism), from cell population dynamiCS (haemopoiesis) and from biochemical kinetics (the Goodwin oscillator). The last chapter is devoted to a population model employing difference equations. All these models include non-linear terms.

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.

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.

Book excerpt: The regular alternation of light and dark affects not only human biological systems, but also the social organization of behavior. The effect of such light modes is manifested in periodic changes in physiological functions and biological rhythms exhibited at every level of life. The book discusses some of the specificities of the circadian rhythms in living organisms and mentions aspects of the control of circadian rhythms as well as experimental and clinical cases that are closely related to circadian disruption. This book can evoke interest in many researchers who want to use this information for the advancement of their research towards a better understanding of the biological time structure.

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: The natural world is full of rhythms. How do birds know when to return to their nesting grounds? What effect do the seasons have on our wellbeing, and how does the season in which we are born affect our subsequent life chances? How did humans get the idea that there were seasons 50,000 years ago? Seasons of Life explains why the seasons occur, the impact of seasonal change and how organisms have evolved to anticipate these changes. For although we mask the effects of seasonal changes by warming our homes, lighting our nights, preserving foods and storing water, we cannot hide from them.
