Animals and plants live in changing environmental conditions which require adaptation in order to cope with this. Some of these environmental changes serve as signals which have to be "sensed" and interpreted correctly by the organisms to initiate the adaptation. This signal processing is based on biochemical, molecular and neuronal processes which are discussed in this book. All examples given underline that continuous adjustment of physiological functions is an essential requirement for life and survival in complex changing environments.

How much do we really know about our number one drug of choice? This book, the first natural, cultural, and artistic history of our favourite mood enhancer tells us more, by looking at how caffeine was discovered, its early uses, and the unexpected parts it has played in medicine, religion, painting, poetry, learning and love.
The World of Caffeine is a captivating tale of art and society containing many fascinating stories including:
* how Balzac's addiction to caffeine drove him to eat coffee and may have killed him
* how a mini Ice Age may have helped bring coffee, tea and chocolate to popularity in Europe
* how caffeine, in its various forms, was used as cash in China, Africa, Central America and Egypt.

This is awide-ranging and persuasive book written by an undisputed expert. Beginning with a broad history of the Universe, Earth, Life, and Man, it considers the origins and rise of science and technology, before moving on to discuss the present state of the world and its/our possible futures." Humans on Earth" then addresses the main challenges for social and economic development in the 21st century in the context of global change. It presents a detailed but non-technical analysis of questions relating to climate change, our dependence on fossil fuels, deforestation, loss of biodiversity, desertification, and air, water, soil, and ocean pollution, as well as problems related to overpopulation, poverty, social and economic inequalities, and conflict potential. The three main, but largely mutually exclusive, discourses on human development and the environment are described and discussed. The main emphasis is on the risks and uncertainties of the short-term future the next 50 to 100 years with regard to environmental degradation and the sustainability of our growth paradigm.

Heart of Darkness describes the incredible saga of humankind's quest to unravel the deepest secrets of the universe. Over the past thirty years, scientists have learned that two little-understood components--dark matter and dark energy--comprise most of the known cosmos, explain the growth of all cosmic structure, and hold the key to the universe's fate. The story of how evidence for the so-called "Lambda-Cold Dark Matter" model of cosmology has been gathered by generations of scientists throughout the world is told here by one of the pioneers of the field, Jeremiah Ostriker, and his coauthor Simon Mitton. From humankind's early attempts to comprehend Earth's place in the solar system, to astronomers' exploration of the Milky Way galaxy and the realm of the nebulae beyond, to the detection of the primordial fluctuations of energy from which all subsequent structure developed, this book explains the physics and the history of how the current model of our universe arose and has passed every test hurled at it by the skeptics. Throughout this rich story, an essential theme is emphasized: how three aspects of rational inquiry--the application of direct measurement and observation, the introduction of mathematical modeling, and the requirement that hypotheses should be testable and verifiable--guide scientific progress and underpin our modern cosmological paradigm. This monumental puzzle is far from complete, however, as scientists confront the mysteries of the ultimate causes of cosmic structure formation and the real nature and origin of dark matter and dark energy.

Time. Gravity. Night. So much of what surrounds us feels familiar and mundane. But each is a wonder that reveals profound insights into the world around us.

C. Renee James's whimsical tour of seven everyday experiences--night, light, stuff, gravity, time, home, and wonder--opens the Universe to fantastical contemplation. Light? Although we need it to see, there's much more to it than meets the eye. Stuff? When it comes down to it, things are almost entirely empty space--99.9% nothing--especially when you get to the atomic level. Home? James's contemplation of our place in the Universe shows that it's not just a place to hang your hat--and that there's really nothing else like it.

James introduces each of these seven wonders with a simple question that appears to be easily answered. The questions are deceptive, though--as is James's casual, light-hearted style. Underneath lie such concepts as relativity, matter and antimatter, and the electromagnetic spectrum. Her accessible discussion uses common analogies and entertaining illustrations to provide a bundle of detail on historical discoveries and to provoke serious pondering.

Fun and edifying, "Seven Wonders of the Universe That You Probably Took for Granted" is an inviting introduction to secret knowledge of our everyday world. This book may be 99.9% nothing, but the thoughts it will inspire are massive.

A Sunday Times bestseller How long is 'now'? The short answer is 'somewhere between 2 and 3 seconds'. The long answer involves an incredible journey through neuroscience, our subconscious and the time-bending power of meditation. Living in the present may never feel the same. Ready for some more? Okay. Why isn't Pluto a planet? Why are dogs' noses wet? Why do hens cluck more loudly after laying an egg? What happens when one black hole swallows another? Do our fingerprints change as we get older? How young can you die of old age? And what is at the very edge of the Universe? Life is full of mind-bending questions. And, as books like What If? and Why Don't Penguins' Feet Freeze? have shown, the route to find each answer can take us on the weirdest and most wonderful journeys. How Long is Now? is a fascinating new collection of questions you never thought to ask, along with answers that will change the way you see everything.

In Dying for Heaven, Georgetown scholar and advisor to the defense community Ariel Glucklich explains the religious motivation of terrorism. This provocative work of political science argues that the very best qualities of religion--its ability to make people feel good and bring them together--are in fact its most dangerous. Glucklich, author of Sacred Pain and Climbing Chamundi Hill, offers a new understanding of religion and provides a vision for preventing further religiously-inspired violence.

Internationally acclaimed science writer Lone Frank swabs up her DNA to provide the first truly intimate account of the new science of consumer-led genomics. She challenges the business mavericks intent on mapping every baby's genome, ponders the consequences of biological fortune-telling, and prods the psychologists who hope to uncover just how much or how little our environment will matter in the new genetic century - a quest made all the more gripping as Frank considers her family's and her own struggles with depression.

In 2004 a rock star, a TV astronomer and a young research astronomer sat down to write the story of the Universe in the order in which it happened, from its birth at the Big Bang 13.7 billion years ago, through to its ultimate demise in the infinitely far future. The aim of this book is to explain the Big Bang and everything that followed in a way that made sense, in the strict order in which events occurred, and without using maths, so it would be understandable to everyone, regardless of educational background. The original edition of Bang! was a bestseller, and a go-to for anyone wanting to understand the story of the origins and evolution of our Universe that did not duck the science. Since the first edition, thousands of planets have been discovered, the 'habitable zone' has expanded and a flotilla of new satellites has explored our own solar system, bringing back fresh images and new science. In this book all the latest findings about the evolution of stars and galaxies are included, and the current thinking about our ultimate origins. The latest ideas about Dark Matter and Dark Energy are explained, all illustrated with new images from the world's largest telescopes and space missions. This is the new, updated, popular guide to 'Life, the Universe, and Everything' - The Complete History of the Universe.

'Holgate guides us expertly and with a deft touch along the journey towards the holy grail of unlimited energy for all.' - JIM AL-KHALILI 'What is nuclear fusion? In clear and accessible language, this book explains the basics and the hope for the future. A valuable addition to the Hot Science series.' - JOHN GRIBBIN Could the Sun hold the key to a future of clean energy? Since the 1950s, scientists have attempted to harness nuclear fusion - the process that creates the Sun's energy - to generate near-limitless amounts of electricity. But the fact that we still have no fusion power plants is testament to the complexities of the challenge. Now, the deepening climate crisis means that researchers around the world are in a race to create a mini-Sun here on Earth. The glittering prize is an energy source that emits no greenhouse gases and could solve energy equity and supply issues at a stroke. Sharon Ann Holgate, a former Young Professional Physicist of the Year, tells the compelling story of the ongoing scientific quest for a revolutionary new era of green energy production.

Emigrating Beyond Earth puts space colonization into the context of human evolution. Rather than focusing on the technologies and strategies needed to colonize space, the authors examine the human and societal reasons for space colonization. They make space colonization seems like a natural step by demonstrating that if will continue the human species' 4 million-year-old legacy of adaptation to difficult new environments. The authors present many examples from the history of human expansion into new environments, including two amazing tales of human colonization - the prehistoric settlement of the upper Arctic around 5,000 years ago and the colonization of the Pacific islands around 3,000 years ago - which show that space exploration is no more about rockets and robots that Arctic exploration was about boating!

Curtis Ebbesmeyer is no ordinary scientist. He's been a consulting oceanographer for multinational firms and a lead scientist on international research expeditions, but he's never held a conventional academic appointment. He seized the world's imagination as no ordinary scientist could when he and his worldwide network of beachcomber volunteers traced the ocean's currents using thousands of sneakers and plastic bath toys spilled from storm-tossed freighters. Now, for the first time, Ebbesmeyer tells the story of his lifelong struggle to solve the sea's mysteries, and shares his most surprising discoveries. He recounts how flotsam has changed the course of history-leading Viking mariners to safe harbours, Columbus to the New World, and Japan to open up to the West - and how it may even have made the origin of life possible. He explores the vast floating garbage patches and waste-heaped junk beaches that collect the flotsam and jetsam of industrial society. Finally, he reveals the music-like mathematical order in oceanic gyres and the threats that global warming and disintegrating plastic waste pose to the seas ...and to us.

THE PHENOMENAL BESTSELLER FROM THE AUTHOR OF HELGOLAND AND THE ORDER OF TIME 'The perfect antidote to the fluff and nonsense around right now. Learn how the world is and how you might just fit in' Simon Mayo 'By God, it's beguiling' New Statesman These seven short lessons guide us, with simplicity and clarity, through the scientific revolution that shook physics in the twentieth century and still continues to shake us today. In this mind-bending overview of modern physics, Carlo Rovelli explains Einstein's theory of general relativity, quantum mechanics, black holes, the complex architecture of the universe, elementary particles, gravity, and the nature of the mind. Not since Richard Feynman's celebrated Six Easy Pieces has physics been so vividly, intelligently and entertainingly revealed. Translated by Simon Carnell and Erica Segre

From avalanches to glaciers and seals to snowflakes, from igloos to icebergs, permafrost to hoarfrost, chilblains to frostbite, Bill Streever unearths the consistent, ongoing influence of cold on the planet. Evoking history, myth, geography and ecology, Streever's quest for icy, forty-below cold gains purchase in July, while he's taking a dip in an Arctic swimming hole; in September, while excavating our planet's ice ages; and in October, while exploring animals' hibernation habits, from humans to wood frogs to bears. In March he even does his best to escape it, bundling up in layers of polyester, spandex and Primaloft fill to face thermometers reading twenty-three below. Streever visits an underground Cold War-era tunnel, where preserved remains mingle with new-fangled machinery and gear; weighs in on the scientific quest to reach absolute zero (-459 F); and describes how refrigeration evolved from worldwide ice shipping to the chemical coolants we know today.

Man is the best thing in the World. Nature does nothing uselessly. Aristotle There is a pleasure in the pathless woods, There is rapture on the lonely shore, There is society, where none intrudes, By the deep sea, and music in its roar: I love not Man the less, but Nature more. John Burroughs The basic purpose of development is to enlarge people's choices. The objective of development is to create an enabling environment for people to enjoy long, healthy and creative lives. Mahbub ul Hag Founder of the Human Development Report Theaimofthisbookis toprovidea compiledset ofconcepts,principles,methods and issues used for studying, designing and operating human-minding and natu- minding automation and industrial systems. The depth of presentation is suf?cient for the reader to understand the problems involved and the solution approaches, and appreciate the need of human-automation cooperative interaction, and the - portance of the efforts required for environment and ecosystem protection during any technological and development process in the society. Humans and technology are living and have to live together in a sustainable society and nature. Humans must not be viewed as components of automation and technology in the same way as machines. Automation and technology must incorporate the humans' needs and preferences, and radiate "beauty" in all ways, namely functionally, technically and humanistically. In overall, automation and technology should create comfort and give pleasure.

This volume is a compilation of the papers presented at a meeting that took place in April 1980 at the Mote Marine Laboratory, Sarasota, Florida. The meeting and this volume are outgrowths of two earlier international meetings on marine bio-acoustics that occurred in 1963 and 1966 (Tavolga 1964, 1967). The first meeting took place at the Lerner Marine Laboratory of the American Museum of Natural History, while the second meeting was at the American Museum itself, and was under the sponsorship of the Department of Animal Behavior. It is apparent that these two volumes have had immense impact on the current study of marine bio-acoustics, and particularly on fish audition. In a preliminary conference in Sarasota in 1979 we decided that it was time for another such meeting, to bring together as many as possible of the investigators interested in fish acoustics in order to assess the current state of our knowledge and predict directions for research for the next several years. Such a meeting appeared par ticularly timely, since over the past four or five years there have been many new studies that have provided new empirical and theoretical work on basic mechanisms of fish audition. Furthermore, it became evident, as we made up preliminary lists of possible participants, that few of the currently active workers were in the field back in 1966. In fact, of the current participants, only Drs."

When physicist Robert Goddard, whose career was inspired by H. G. Wells's War of the Worlds, published "A Method of Reaching Extreme Altitudes," the response was electric. Newspaper headlines across the country announced, "Modern Jules Verne Invents Rocket to Reach Moon," while people from around the world, including two World War I pilots, volunteered as pioneers in space exploration. Though premature (Goddard's rocket, alas, was only imagined), the episode demonstrated not only science's general popularity but also its intersection with interwar popular and commercial culture. In that intersection, the stories that inspired Goddard and others became a recognizable genre: science fiction. Astounding Wonder explores science fiction's emergence in the era's "pulps," colorful magazines that shouted from the newsstands, attracting an extraordinarily loyal and active audience.

Pulps invited readers not only to read science fiction but also to participate in it, joining writers and editors in celebrating a collective wonder for and investment in the potential of science. But in conjuring fantastic machines, travel across time and space, unexplored worlds, and alien foes, science fiction offered more than rousing adventure and romance. It also assuaged contemporary concerns about nation, gender, race, authority, ability, and progress—about the place of ordinary individuals within modern science and society—in the process freeing readers to debate scientific theories and implications separate from such concerns.

Readers similarly sought to establish their worth and place outside the pulps. Organizing clubs and conventions and producing their own magazines, some expanded science fiction's community and created a fan subculture separate from the professional pulp industry. Others formed societies to launch and experiment with rockets. From debating relativity and the use of slang in the future to printing purple fanzines and calculating the speed of spaceships, fans' enthusiastic industry revealed the tensions between popular science and modern science. Even as it inspired readers' imagination and activities, science fiction's participatory ethos sparked debates about amateurs and professionals that divided the worlds of science fiction in the 1930s and after.

For you to be here today reading this requires a mind-boggling series of lucky breaks, starting with the Big Bang and ending in your own conception. So it's not surprising that we persist in thinking that we're in with a chance, whether we're playing the lottery or working out the likelihood of extra-terrestrial life. In Chance, a (not entirely) random selection of the New Scientist's sharpest minds provide fascinating insights into luck, randomness, risk and probability. From the secrets of coincidence to placing the perfect bet, the science of random number generation to the surprisingly haphazard decisions of criminal juries, it explores these and many other tantalising questions. Following on from the bestselling Nothing and Question Everything, this book will open your eyes to the weird and wonderful world of chance - and help you see when some things, in fact, aren't random at all.

There are many unanswered questions regarding the molecular nature of antibodies, components of complement, and other substances which participate in the immune response. The list of substances which need to be analyzed chemically is increasing. Plasma cell products, of course, have long been of great interest because the most prevalent ones are immunoglobulins. Other cell types, however, are the source of the broad spectrum of additional substances which classically fall into the sanctum of the molecular immunologist. It is these substances, and especially those more recently discovered, which are responsible for the broadening investigative interests of immunologists. In this volume we have provided you with descriptions of research being done with immunoglobulins and with complement. Additionally, we have in cluded two reports that deal with molecules which are among the more recent acquisitions of the molecular immunologist. The components of complement are known to react in a cascading manner which results in the lysis of cellular antigens. The first step in the classical pathway requires the activation of CI by the antibody-antigen aggregates. This volume of Contemporary Topics in Molecular Immunology begins with the report of Reid and Porter which describes their investigation of the mechanism of activation of C I. Their descriptions of C I q and of the reaction of C I with immunoglobulins are especially intriguing. It is clearly apparent from their report that activation of the components of complement is a complex phenome non.

To scientists engaged in research on the cellular mechanisms in the mammalian brain, concepts of "motivation" seem to be a logical neces sity, even if they are not fashionable. Immersed in the detailed, time consuming research required to deal with mammalian nerve cells, we usually pay scant attention to the more global brain -behavior questions that have arisen from decades of biological and psychological studies. We felt it was time to confront these issues-namely, how far has neuro biological investigation come in uncovering mechanisms by which moti vational signals influence behavior? At Rockefeller University, we have recently held a course on this subject. We restricted our treatment to those motivational systems most tractable to physiological approaches, and invited scientists skilled in both behavioral issues and physiological techniques to participate. This volume results from that course. The deans and administration at Rockefeller University provided much help in planning the course, and the staff of Springer-Verlag assisted in planning the book. Gabriele Zummer helped organize both the course and the processing of book chapters. They all deserve our thanks. December 1981 Donald W.

A classic since its first appearance in the 1980s, this comprehensive reference continues to be the history of the spread of new ideas, for academics and professionals alike. In an age of ever-increasing technological innovation, this renowned volume--which has sold more than 30,000 copies in each edition--is more important than ever. Diffusion of Innovations lucidly explains how inventions and new concepts spread via communication channels over time. As professor Everett Rogers explains, such innovations are almost always perceived as uncertain or even risky. To overcome this, most people seek out others like themselves who have already adopted the new idea. The diffusion process, then, is most often shaped by a few individuals who spread the world amongst their circle of acquaintances, a process that typically takes months or years. But there are exceptions: use of the Internet in the 1990s, for instance, may have spread more rapidly than any other innovation in human history--and it continues to influence the very nature of diffusion by decreasing the significance of physical distance between people. As thought-provoking as it is instructive, this fully updated, widely acclaimed work of scholarship is itself a great idea that continues to spread.

With more than 50% of the world's population already living in towns and cities, migration from rural areas continuing at an alarming rate in developing countries and suburbanisation using more and more land in developed countries, the urban environment has become supremely important with regard to human health and wellbeing. For centuries, urbanisation has caused relatively low level soil conta- nation mainly by various wastes. However, from the time of the Industrial Revolution onwards, both the scale of urban development and the degree of soil contamination rapidly increased and involved an ever widening spectrum of c- taminants. With constraints on the supply of land for new urban development in many countries, it is becoming increasingly necessary to re-use previously dev- oped (brownfield) sites and to deal with their accompanying suites of contaminants. It is therefore essential to fully understand the diversity and properties of urban soils, to assess the possible risks from the contaminants they contain and devise ways of cleaning up sites and/or minimizing hazards. The author, Helmut Meuser, is Professor of Soil Protection and Soil Clean-up at the University of Applied Sciences, Osnabruck and is one of Europe's foremost experts on contamination from technogenic materials in urban soils. He has many years' experience of research in Berlin, Essen, Osnabruck, other regions of Germany, and several other countries.

Stephen Webb, author of WHERE IS EVERYBODY?, takes the interested amateur on a thrilling and enlightening tour of the amazing, even bizarre, new ideas of modern physics, including alternatives to the Big Bang, parallel universes, and an imaginary trip to the other side of the black hole.

Few scientists have made lasting contributions to as many fields as Francis Galton. He was an important African explorer, travel writer, and geographer. He was the meteorologist who discovered the anticyclone, a pioneer in using fingerprints to identify individuals, the inventor of regression and correlation analysis in statistics, and the founder of the eugenics movement. Now, Nicholas Gillham paints an engaging portrait of this Victorian polymath.
