This book was released on 2022-10-11 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: In three volumes, historian Jole Shackelford delineates the history of the study of biological rhythms—now widely known as chronobiology—from antiquity into the twentieth century. Perhaps the most well-known biological rhythm is the circadian rhythm, tied to the cycles of day and night and often referred to as the “body clock.” But there are many other biological rhythms, and although scientists and the natural philosophers who preceded them have long known about them, only in the past thirty years have a handful of pioneering scientists begun to study such rhythms in plants and animals seriously. Tracing the intellectual and institutional development of biological rhythm studies, Shackelford offers a meaningful, evidence-based account of a field that today holds great promise for applications in agriculture, health care, and public health. Volume 1 follows early biological observations and research, chiefly on plants; volume 2 turns to animal and human rhythms and the disciplinary contexts for chronobiological investigation; and volume 3 focuses primarily on twentieth-century researchers who modeled biological clocks and sought them out, including three molecular biologists whose work in determining clock mechanisms earned them a Nobel Prize in 2017.

Available in PDF, EPUB and Kindle. Book excerpt: This book represents the first in a two-volume set on biological rhythms. This volume focuses on supporting the claim that biological rhythms are universal and essential characteristics of living organisms, critical for proper functioning of any living system. The author begins by examining the potential reasons for the evolution of biological rhythms: (1) the need for complex, goal-oriented devices to control the timing of their activities; (2) the inherent tendency of feedback control systems to oscillate; and (3) the existence of stable and powerful geophysical cycles to which all organisms must adapt. To investigate the second reason, the author enlists the help of biomedical engineering students to develop mathematical models of various biological systems. One such model involves a typical endocrine feedback system. By adjusting various model parameters, it was found that creating a oscillation in any component of the model generated a rhythmic cascade that made the entire system oscillate. This same approach was used to show how daily light/dark cycles could cascade rhythmic patterns throughout ecosystems and within organisms. Following up on these results, the author discusses how the twin requirements of internal synchronization (precise temporal order necessary for the proper functioning of organisms as complex, goal-oriented devices) and external synchronization (aligning organisms' behavior and physiology with geophysical cycles) supported the evolution of biological clocks. The author then investigates the clock systems that evolved using both conceptual and mathematical models, with the assistance of Dr. Bahrad Sokhansanj, who contributes a chapter on mathematical formulations and models of rhythmic phenomena. With the ubiquity of biological rhythms established, the author suggests a new classification system: the F4LM approach (Function; Frequency; waveForm; Flexibility; Level of biological system expressing rhythms; and Mode of rhythm generation) to investigate biological rhythms. This approach is first used on the more familiar cardiac cycle and then on neural rhythms as exemplified and measured by the electroencephalogram. During the process of investigating neural cycles, the author finds yet another reason for the evolution of biological rhythms: physical constraints, such as those imposed upon long distance neural signaling. In addition, a common theme emerges of a select number of autorhythmic biological oscillators imposing coherent rhythmicity on a larger network or system. During the course of the volume, the author uses a variety of observations, models, experimental results, and arguments to support the original claim of the importance and universality of biological rhythms. In Volume 2, the author will move from the establishment of the critical nature of biological rhythms to how these phenomena may be used to improve human health, well-being, and productivity. In a sense, Volume 1 focuses on the chronobio aspect of chronobioengineering while Volume 2 investigates methods of translating this knowledge into applications, the engineering aspect of chronobioengineering.

Available in PDF, EPUB and Kindle. Book excerpt: Winner of a British Medical Association Book Award A Brain Pickings Best Science Book of the Year Early birds and night owls are born, not made. Sleep patterns may be the most obvious manifestation of the highly individualized biological clocks we inherit, but these clocks also regulate bodily functions from digestion to hormone levels to cognition. Living at odds with our internal timepieces, Till Roenneberg shows, can make us chronically sleep deprived and more likely to smoke, gain weight, feel depressed, fall ill, and fail geometry. By understanding and respecting our internal time, we can live better. “Internal Time is a cautionary tale—actually a series of 24 tales, not coincidentally. Roenneberg ranges widely from the inner workings of biological rhythms to their social implications, illuminating each scientific tutorial with an anecdote inspired by clinical research...Written with grace and good humor, Internal Time is a serious work of science incorporating the latest research in chronobiology...[A] compelling volume.” —A. Roger Ekirch, Wall Street Journal “This is a fascinating introduction to an important topic, which will appeal to anyone who wishes to delve deep into the world of chronobiology, or simply wonders why they struggle to get a good night’s sleep.” —Richard Wiseman, New Scientist

Download or read book The Tribal Imagination written by Robin Fox and published by Harvard University Press. This book was released on 2011-03-08 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: We began as savages, and savagery has served us well—it got us where we are. But how do our tribal impulses, still in place and in play, fit in the highly complex, civilized world we inhabit today? This question, raised by thinkers from Freud to Lévi-Strauss, is fully explored in this book by the acclaimed anthropologist Robin Fox. It takes up what he sees as the main—and urgent—task of evolutionary science: not so much to explain what we do, as to explain what we do at our peril. Ranging from incest and arranged marriage to poetry and myth to human rights and pop icons, Fox sets out to show how a variety of human behaviors reveal traces of their tribal roots, and how this evolutionary past limits our capacity for action. Among the questions he raises: How real is our notion of time? Is there a human “right” to vengeance? Are we democratic by nature? Are cultural studies and fascism cousins under the skin? Is evolutionary history coming to an end—or just getting more interesting? In his famously informative and entertaining fashion, drawing links from Volkswagens to Bartók to Woody Guthrie, from Swinburne to Seinfeld, Fox traces our ongoing struggle to maintain open societies in the face of profoundly tribal human needs—needs which, paradoxically, hold the key to our survival.

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.

Download or read book Cycles of Nature written by Andrew Ahlgren and published by National Science Teachers Assn. This book was released on 1990 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an outlined for the short study (1- to 2-weeks) of chronobiology, a field of science that explores the relationships between time and biological functions. It develops step-by-step the reasoning that leads to the current scientific understanding of biological rhythms. The unit can be inserted into a standard middle or high school biology course. Because the scientific study of biological rhythms begins with data, Chapter 1 provides a brief review of the ways to collect, graph, and interpret data. Chapter 2 introduces some of the cycles in nature, especially those of the human body-from dream cycles to menstruation to body temperature. Chapter 3 explores how these cycles come about and explains the differences between external and internal influences. Chapter 4 explores the internal workings of organisms to determine whether there is a single master source of timing information that synchronizes an organism's many interacting cycles. Chapter 5 discusses the impact of rhythms on society and asks how an understanding of them could bring progress in medicine, work schedules, and everyday life. Chapter 6 offers a brief historical perspective on the study of biological rhythms, and chapter 7 outlines eight activities that demonstrate cycles in chemicals, plants, and animals. Each activity includes an introduction, materials, set-up, procedures, and possible extensions. (KR)

Download or read book Data Centric Biology written by Sabina Leonelli and published by University of Chicago Press. This book was released on 2016-11-18 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last two decades, digital access to data has revolutionized research methods and ways of doing science in the biological and biomedical fields. Prominent scientists have characterized this shift as leading to a new, "data-intensive" paradigm for research, encompassing innovative ways to produce, store, disseminate, and interpret huge masses of data. In this book Sabina Leonelli explores the epistemological challenges this poses to how life is researched and understood. By following how data travels across research contexts, and the role played by standards, theories, models, and human agency in shaping their evidential value, she shows the conditions under which digitally available data further our understanding of life. Turning to how the characteristics of data-intensive science bear on philosophical debates, Leonelli explores the shifting criteria for what counts as scientific evidence and how data are transformed into new knowledge. In short, she argues that a philosophical characterization of how data and knowledge move from one context to another is of fundamental importance to a productive philosophical understanding of contemporary scientific practices.

Download or read book A Philosophical Path for Paracelsian Medicine written by Jole Shackelford and published by Museum Tusculanum Press. This book was released on 2004 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: The great Paracelsian scholar Walter Pagel and the pioneer medical historian Kurt Polycarp Sprengel identified Petrus Severinus' Idea Medicinæ (1571) as an influential vehicle for the elaboration and diffusion of Paracelsian ideas in the late sixteenth and early seventeenth centuries, a process that has recently come under renewed scrutiny. Severinus' conception that diseases grow from living, seed-like entities proved to be an especially important idea, which was recognized by prominent scientific and medical authors from Oswald Croll and Daniel Sennert to Pierre Gassendi and Robert Boyle. But they also formed a useful theoretical model for reconciling ideas about physical causation with certain Christian Platonist concerns in Protestant theology. A Philosophical Path for Paracelsian Medicine is the first book-length monograph to treat Severinus, a Danish royal physician and contemporary of the great astronomer Tycho Brahe, and to present his ideas in their historical context as well as considering their ramifications for medical and religious theory in the decades prior to the Thirty Years' War. This book will prove to be a useful tool in the reexamination of the process by which Paracelsian ideas were spread and assimilated and will appeal to all those interested the intellectual background for the work of Tycho Brahe and his students and the role of Paracelsian and Hermetic metaphysical ideas in the scientific revolution of the seventeenth century.

Download or read book Biological Clocks written by Yvan Touitou and published by Elsevier Publishing Company. This book was released on 1998 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hardbound. This volume comprises the lectures and a selection of communications presented at the International Congress on Chronobiology, held in Paris, in September, 1997. During the last three decades it has been shown that a number of physiologic functions are regulated by a system of clocks controlling basel levels of activity and responsitivity to changes in the environment. At the beginning of this century (1935) Erwin Bunning was the first to demonstrate that plants and insects still displayed circadian rhythms after they or their parents were raised in constant conditions. Later on, he was the first to demonstrate that circadian clocks measure the length of the day. In the 1950s, Colin Pittendrigh provided strong evidence that circadianphenomena are not learned but they display endogenous properties, the periods of which are independent of environmental factors. Since then, a number of investigations have extensively documented properties

Download or read book The Circadian Code written by Satchin Panda, PhD and published by Rodale Books. This book was released on 2018-06-12 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: When we eat may be as important as what we eat. Like most people, you probably wake up, get hungry for meals and doze off in bed around the same time every day. If you’ve ever experienced jet lag or pulled an all-nighter, you know that this schedule can easily be thrown off kilter. But for some people, that imbalance—difficulty sleeping at night, hunger at odd times, or sudden fatigue at noon—is a constant. If you're one of those people, Dr. Satchin Panda, one of the leading researchers on circadian rhythms, has a plan to reset your body clock. Beginning with an in-depth explanation of the circadian clock—why it’s important, how it works, and how to know it isn’t working—The Circadian Code outlines lifestyle changes to make to get back on track. It's a concrete plan to enhance weight loss, improve sleep, optimize exercise, and manage technology so that it doesn’t interfere with your body’s natural rhythm. Dr. Panda’s life-changing methods show you how to prevent and reverse ailments like diabetes, cancer, and dementia, as well as microbiome conditions like acid reflux, heartburn, and irritable bowel disease.

Download or read book William Harvey and the Mechanics of the Heart written by Jole Shackelford and published by Oxford University Press. This book was released on 2003-10-30 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: William Harvey is the riveting story of a seventeenth-century man of medicine and the scientific revolution he sparked with his amazing discoveries about blood circulation within the body. Jole Shackelford traces Harvey's life from his early days in Folkstone, England, to his study of medicine in Padua through his rise to court physician to King James I and King Charles I, where he had the opportunity to conduct his research in human biology and physiology. Harvey's lecture notes show that he believed in the role of the heart in circulation of blood through a closed system as early as 1615. Yet he waited 13 years, until 1628, to publish his findings, when he felt more secure at introducing a concept counter to beliefs that had been held for hundreds of years. A revealing look at the changing social, religious, and political beliefs of the time, William Harvey documents how one man's originality helped introduce a new way of conducting scientific experiments that we still use today.
