Available in PDF, EPUB and Kindle. Book excerpt: "Radioactivity is like a clock that never needs adjusting," writes Doug Macdougall. "It would be hard to design a more reliable timekeeper." In Nature's Clocks, Macdougall tells how scientists who were seeking to understand the past arrived at the ingenious techniques they now use to determine the age of objects and organisms. By examining radiocarbon (C-14) dating—the best known of these methods—and several other techniques that geologists use to decode the distant past, Macdougall unwraps the last century's advances, explaining how they reveal the age of our fossil ancestors such as "Lucy," the timing of the dinosaurs' extinction, and the precise ages of tiny mineral grains that date from the beginning of the earth's history. In lively and accessible prose, he describes how the science of geochronology has developed and flourished. Relating these advances through the stories of the scientists themselves—James Hutton, William Smith, Arthur Holmes, Ernest Rutherford, Willard Libby, and Clair Patterson—Macdougall shows how they used ingenuity and inspiration to construct one of modern science's most significant accomplishments: a timescale for the earth's evolution and human prehistory.

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.

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.

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