"With the fresh perspective of a curious and insightful non-scientist, Mr. Klein examines the question of what force, time or tide, actually provides more influence over cellular biomechanics."--Global Books in Print.

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

Crops. Like the animals and plants around us, we are tuned to the cycles of our planet. Time cycles, encoded into our cells, tell us when to sleep and wake, work and play. When we ignore them, we put both our health and our happiness at risk. The development of chronobiology represents a new era in our understanding of the universe. Like the discovery of the microscope, chronobiology is revolutionizing how we view ourselves and our world on every level. Inner Time.

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.

How the groundbreaking science of circadian rhythms can help you sleep better, feel happier, and improve your overall health Your body contains a symphony of tiny timepieces, synchronized to the sun and subtle signals in your environment and behavior. But modern insults like artificial light, contrived time zones, and late-night meals can wreak havoc on your internal clocks. Armed with advances in biology and technology, a circadian renaissance is reclaiming those lost rhythms. The Inner Clock explores the emerging science and its transformative applications: How could taking a walk in the morning and going to bed at the same time each night keep your body in sync? Why are some doctors prescribing treatments at specific times of day? And how might a better understanding of our circadian rhythms improve educational outcomes, optimize sports performance, and support the longevity of our planet? Science journalist Lynne Peeples seeks out the scientists, astronauts, athletes, and patients at the forefront of a growing movement. Along the way, she sleeps in a Cold War-era bunker, chases the midnight sun, spits into test tubes, and wears high-tech light sensors to decipher what makes our internal clocks tick and how we can reset them for the better.

In Tides: The Science and Spirit of the Ocean, writer, sailor, and surfer Jonathan White takes readers across the globe to discover the science and spirit of ocean tides. In the Arctic, White shimmies under the ice with an Inuit elder to hunt for mussels in the dark cavities left behind at low tide; in China, he races the Silver Dragon, a twenty-five-foot tidal bore that crashes eighty miles up the Qiantang River; in France, he interviews the monks that live in the tide-wrapped monastery of Mont Saint-Michel; in Chile and Scotland, he investigates the growth of tidal power generation; and in Panama and Venice, he delves into how the threat of sea level rise is changing human culture—the very old and very new. Tides combines lyrical prose, colorful adventure travel, and provocative scientific inquiry into the elemental, mysterious paradox that keeps our planet’s waters in constant motion. Photographs, scientific figures, line drawings, and sixteen color photos dramatically illustrate this engaging, expert tour of the tides.

From one-celled paramecium to giant blue whales, we all have internal clocks that regulate the rhythms we live by. In The Living Clock, John Palmer, one of the world's leading authorities on these rhythms, takes us on a tour of this broad and multifaceted subject, examining everything from glowing fruit flies to the best cures for jet lag. Palmer has a wonderful sense of humor and an eye for the startling fact. We learn that fiddler crabs--in a lab where there are no time nor tide cues--remain active when low tide would occur and motionless during high tide, the same pattern they follow in their natural habitat. (In fact, you can remove a crab's leg and the leg will keep a tidal rhythm as long as it's kept alive.) Moreover, humans are subject to more than one hundred biological rhythms. Mental acuity peaks in the afternoon, for instance, and our blood pressure peaks at seven in the morning (when most heart attacks occur). The time of day you take medication can affect how well it works. And Palmer shows that when our clocks are thrown off kilter, trouble follows, especially for rotating shift workers--the Bhopal spill, the Chernobyl reactor explosion, and the Three Mile Island accident all happened when new crews began early-hour shifts. No one has discovered exactly how our internal clocks work--Palmer says a Nobel Prize awaits that lucky scientist--but they are no less fascinating for their inexplicable nature. Frequently amusing and always eye-opening, The Living Clock is a treat for everyone curious about the nature of life as well as anyone planning a long jet flight.
