What does a mammoth smell like? Do dinosaurs bob their heads as they walk, like today’s birds? Do aurochs moo like cows? You may soon find out. From the Siberian permafrost to balmy California, scientists across the globe are working to resurrect all kinds of extinct animals, from ones that just left us to those that have been gone for many thousands of years. Their tools in this hunt are both fossils and cutting-edge genetic technologies. Some of these scientists are driven by sheer curiosity; others view the lost species as a powerful weapon in the fight to save rapidly disappearing ecosystems. Science journalist Torill Kornfeldt travelled the world to meet the men and women working to bring extinct animals back from the dead. Along the way, she saw a mammoth that has been frozen for 20,000 years, and visited the places where these furry giants once walked. It seems certain that they and other lost species will walk the earth again, but what world will that give us? And is any of this a good idea?
Dieses nahezu vollständig überarbeitete und um zwei gänzlich neue Kapitel erweiterte Werk ist weit mehr als nur eine 2. Auflage. Denn in den letzten 20 Jahren haben Herausgeber und Mitautoren viel Neues und Verblüffendes über das Mittelmeer erfahren. Eine neue Wissenschaft hat sich formiert, die multidisziplinäre Mediterranistik, die dank Historikern neue Einsichten zum Verständnis dieses Raums ermöglicht. Doch auch die Umweltforschung machte große Fortschritte und fördert Beunruhigendes an den Tag: Die negativen Veränderungen im Mittelmeer und im mediterranen Raum laufen heute in einer Geschwindigkeit ab, die es in der Erdgeschichte bisher wahrscheinlich noch nie gegeben hat. Dieses erweiterte Wissen hat Einzug in das Buch gefunden.Der Leser erhält einen weit gefassten Überblick über die Erdgeschichte der mediterranen Region, aber auch über die Rolle unserer Vorfahren darin, den Hominini. Das aktuelle Wissen zum mediterranen Raum ist hier zusammengefasst – von der Biodiversität bis zur wirtschaftlichen Nutzung der marinen Ressourcen, von den klimatischen Verhältnissen, den Wasserströmungen und Winden bis zu den komplexen Nahrungsnetzen und ökologischen Abhängigkeiten innerhalb der Pflanzen- und Tierwelt des Mittelmeeres. Die enorme Bandbreite der Themen soll Liebhabern der Mittelmeerregion ebenso entgegenkommen wie Meeresschützern, Tauchern, Forschern, Seglern und Reisenden – jedem, der über das Mittelmeer etwas wissen will. Hunderte von eigens für dieses Werk entwickelten Grafiken veranschaulichen die in zwölf Kapiteln besprochenen Phänomene, Prozesse und Konzepte. Zahlreiche Tabellen fassen die Ergebnisse umfangreicher Recherchen zusammen. Farblich hervorgehobene Exkurse beleuchten spannende Einzelaspekte der Natur- und Kulturgeschichte des Mittelmeeres. Eindrucksvolle Farbfotos der mediterranen Lebensräume und ihrer Lebewesen begleiten die informativen Texte. Die Fülle der in diesem Werk verarbeiteten Informationen, die Klarheit der Darstellung und die ansprechende Gestaltung machen Das Mittelmeer zu einem unentbehrlichen Nachschlagewerk und außergewöhnlichen Lesevergnügen zugleich. Der Rat der Autoren: „Tun Sie für die Umwelt mehr als Sie müssen!“
Why do we give a damn about strangers? Altruism is unique to the human species. It is also one of the great evolutionary puzzles, and we may be on the brink of solving it. It turns out that, over the last 12,000 years, we have become more and more altruistic. This is despite the fact that, the majority of the time, our minds are still breathtakingly indifferent to the welfare of others. In solving the enigma of generosity in a world of strangers, McCullough takes us on a sweeping history of society and science to warn that, if we are not careful, our instincts and sympathies have as much potential for harm as for good. The bad news is that we are not designed to be kind. The good news is that we can push ourselves to be kind anyway, together.
"[An] approachable exploration of the jet stream ... The reader is rewarded with plenty of juicy little facts ... a good and surprisingly enjoyable trip around a weather phenomenon." - Brian Clegg, Popular Science A number of extreme weather events have struck the Northern Hemisphere in recent years, from scorching heatwaves to desperately cold winters, and from floods and storms to droughts and wildfires. These events have fuelled intense discussions in scientific conferences, government agencies, cafes, and on street corners around the world. Why are these events happening? Is this the emerging signal of climate change, and should we expect more of this? Media reports vary widely, but one mysterious agent has risen to prominence in many cases: the jet stream. The story begins on a windswept beach in Barbados, from where we follow the ascent of a weather balloon that will travel along the jet stream all around the world. From this viewpoint we observe the effect of the jet in influencing human life around the hemisphere, and witness startling changes emerging. What is the jet stream and how well do we understand it? How does it affect our weather and is it changing? These are the main questions tackled in this book. We learn about how our view of the wind has developed from Aristotle's early theories up to today's understanding. We see that the jet is intimately connected with dramatic contrasts between climate zones and has played a key historical role in determining patterns of trade. We learn about the basic physics underlying the jet and how this knowledge is incorporated into computer models which predict both tomorrow's weather and the climate of future decades. And finally, we discuss how climate change is expected to affect the jet, and introduce the vital scientific debate over whether these changes have contributed to recent extreme weather events.
This book critically examines how mathematical modelling shapes and limits a scientific approach to the natural world and affects how society views nature. It questions concepts such as determinism, reversibility, equilibrium, and the isolated system, and challenges the view of physical reality as passive and inert. Dan Bruiger argues that if nature is real, it must transcend human representations. In particular, it can be expected to self-organize in ways that elude a mechanist treatment. This interdisciplinary study addresses several key areas: the "crisis" in modern physics and cosmology; the limits and historical, psychological, and religious roots of mechanistic thought; and the mutual effects of the scientific worldview upon society's relationship to nature. Bruiger demonstrates that there is still little place outside biology for systems that actively self-organize or self-define. Instead of appealing to "multiverses" to resolve the mysteries of fine-tuning, he suggests that cosmologists look toward self-organizing processes. He also states that physics is hampered by its external focus and should become more self-reflective. If scientific understanding can go beyond a stance of prediction and control, it could lead to a relationship with nature more amenable to survival. The Found and the Made fills a void between popular science writing and philosophy. It will appeal to naturalists, environmentalists, science buffs, professionals, and students of cultural history, evolutionary psychology, gender studies, and philosophy of mind.
'This is a book of miracles. Fascinating... An absorbing compendium of unlikely recoveries from physical and mental ailments offers evidence that the brain can heal... brings Oliver Sacks to mind' Lisa Appignanesi, Observer The Brain's Way of Healing explores the astonishing advances in the discovery of neuroplasticity, showing that the brain has its own unique way of healing, only recently uncovered. Norman Doidge discusses a series of remarkable recoveries: patients told they would never improve have years of chronic pain alleviated or damage from debilitating strokes undone, and symptoms of multiple sclerosis, Parkinson's disease, brain injury, autism or learning disorders are reversed. He also shows how the risk of dementia can be lowered by 60%. Using stories to present cutting-edge science, Doidge illustrates principles that everyone can apply to improve their brain's performance.
How was our universe built? What happened at its beginning? And where do humans fit in? We are a minuscule part of an incredible continuum: a chain of events spanning 13.8 billion years, with an infinite future. But what does that future hold? And will we ever truly understand our cosmic home? The Universe In a Box is Andrew Pontzen's tribute to simulation - the remarkable fusion of technology and science that, over the last century, has allowed us to understand the distant past and far future of the universe. It challenges everything we think we know about galaxies, black holes and matter itself. And it reveals the pioneer scientists who unlocked mysteries of space, from redshift to improbable dark materials that pass, ghost-like, through solid rock. Illuminating, provocative and bold, this is the story of the computer codes that allow us to look up, to learn, and to discover our place in the cosmos.
This book recounts the epic saga of how we as human beings have come to understand the Solar System. The story of our exploration of the heavens, Peter Bond reminds us, began thousands of years ago, with the naked-eye observations of the earliest scientists and philosophers. Over the centuries, as our knowledge and understanding inexorably broadened and deepened, we faltered many times, frequently labored under misconceptions, and faced seemingly insurmountable obstacles to understanding. Yet, despite overwhelming obstacles, a combination of determined observers, brilliant thinkers, courageous explorers, scientists and engineers has brought us, particularly over the last five decades, into a second great age of human discovery. At our present level of understanding, some fifty years into the Space Age, the sheer volume of images and other data being returned to us from space has only increased our appetite for more and more detailed information about the planets, moons, asteroids, and comets of the Solar System. Taking a much-needed overview of how we now understand these "distant worlds" in our cosmic neighborhood, Bond not only celebrates the extraordinary successes of planetary exploration, but reaffirms an important truth: For seekers of knowledge, there will always be more to explore. An astonishing saga of explorationa ] In this much-needed overview of "where we stand today," Peter Bond describes the achievements of the astronomers, space scientists, and engineers who have made the exploration of our Solar System possible. A clearly written and compelling account of the Space Age, the book includes: a [ Dramatic accounts of the daring, resourcefulness, andferocious competitive zeal of renowned as well as almost-forgotten space pioneers. a [ Clear explanations of the precursors to modern astronomy, including how ancient natural philosophers and observers first took the measure of the heavens. a [ More than a hundred informative photographs, maps, simulated scenarios, and technical illustrations--many of them in full color. a [ Information-dense appendices on the physical properties of our Solar System, as well as a comprehensive list of 50 years of Solar System missions. Organized into twelve chapters focused on the objects of our exploration (the individual planets, our Moon, the asteroids and comets), Bonda (TM)s text shows how the great human enterprise of space exploration may on occasion have faltered or wandered off the path, but taken as a whole amounts to one of the great triumphs of human civilization.
IMAGINE A WORLD WHERE parasites control the minds of their hosts, sending them to their destruction. For centuries, parasites have lived in nightmares, horror stories, and in the darkest shadows of science. Yet these creatures are among the world's most successful and sophisticated organisms. In Parasite Rex, Carl Zimmer deftly balances the scientific and the disgusting as he takes readers on a fantastic voyage. Traveling from the steamy jungles of Costa Rica to the fetid parasite haven of southern Sudan, Zimmer graphically brings to life how parasites can change DNA, rewire the brain, make men more distrustful and women more outgoing, and turn hosts into the living dead. This thorough, gracefully written book brings parasites out into the open and uncovers what they can teach us about the most fundamental survival tactics in the universe.
Climate discussions often focus on potential impacts over a long period of time--several decades, a century even. But change could also happen much more suddenly. What if we had a real climate emergency--how could we cool the planet in a hurry? This question has led a group of scientists to pursue extreme solutions: huge contraptions that would suck CO2 from the air, machines that brighten clouds and deflect sunlight away from the earth, even artificial volcanoes that spray heat-reflecting particles into the atmosphere. This is the radical and controversial world of geoengineering. "How to Cool the Planet," Jeff Goodell explores the scientific, political, and moral aspects of geoengineering. How are we going to change the temperature of whole regions if we can't even predict next week's weather? What about wars waged with climate control as the primary weapon? There are certainly risks, but Goodell persuades us that geoengineering may be our last best hope, a Plan B for the environment. And if it is, we need to know enough to get it right.

This book introduces a new topic; a critical researched-based analysis of the role of human judgment in social policy formation. It applies what has been learned from research on human judgment to specific examples - from the Challenger disaster to present-day debates on health care. Human judgment can be a source of both hope and fear in the creation of social policy. Yet this important process has rarely been examined because research on human judgment has been scarce. Now, however, the results of 50 years of empirical work offer an unprecedented opportunity to examine human judgment and the basis of our hopes and fears. Numerous examples from law, medicine, engineering, and economics are used throughout to demonstrate these and other features of human judgment in action.
'Entertaining and enlightening ... offers ways to temper our anti-social tendencies.' Dr Michael Mosley, science journalist and TV presenter It can often seem that we are utterly surrounded by temptation, from the ease of online shopping and the stream of targeted advertising encouraging us to greedily acquire yet more stuff, to the coffee, cake and fast-food shops that line our streets, beckoning us in to over-indulge on all the wrong things. It can feel like a constant battle to stay away from the temptations we know we shouldn't give in to. Where exactly do these urges come from? If we know we shouldn't do something, for the sake of our health, our pockets or our reputation, why is it often so very hard to do the right thing? Anyone who has ever wondered why they never seem to be able to stick to their diet, anyone to whom the world seems more vain and self-obsessed than ever, anyone who can't understand why love-cheats pursue their extra-marital affairs, anyone who struggles to resist the lure of the comfy sofa, or anyone who makes themselves bitter through endless comparison with other people, anyone who is addicted to their smartphone - this book is for you. The Science of Sin brings together the latest findings from neuroscience research to shed light on the universally fascinating subject of temptation - where it comes from, how to resist it and why we all tend to succumb from time to time. With each chapter inspired by one of the seven deadly sins, neurobiologist Jack Lewis illuminates the neural battles between temptation and restraint that take place within our brains, suggesting strategies to help us better manage our most troublesome impulses with the explicit goal of improving our health, our happiness and our productivity - helping us to say 'no!' more often, especially when it really counts.
The spellbinding stories of the scientists whose eureka! breakthroughs in modern physics reveal science's astonishing predictive power. How does it feel to know something about the universe that no one has ever known before? And why is mathematics so good at revealing nature's secrets? This is the story of the scientists who, using mathematics, predicted the existence of unknown planets, black holes, invisible force fields, ripples in the fabric of space-time, unsuspected subatomic particles, and even antimatter. The journey from prediction to proof transports us from seats of learning in Paris and Cambridge to the war-torn Russian front, to bunkers beneath nuclear reactors, observatories in Berlin and California, and huge tunnels under the Swiss-French border. From electromagnetism to Einstein's gravitational waves to Wolfgang Pauli's elusive neutrino, acclaimed science writer Marcus Chown takes us on a breathtaking, mind-altering tour of the major breakthroughs of modern physics and highlights science's central mystery: its astonishing predictive power.
This book presents contributions from an internal symposium organized to celebrate the 80th anniversary of the Specola Vaticana, or Vatican Observatory, in the Papal Palace of Castel Gandolfo. The aim is to provide an overview of the scientific and cultural work being undertaken at the Observatory today and to describe the outcomes of important recent investigations. The contents cover interesting topics in a variety of areas, including planetary science and instrumentation, stellar evolution and stars, galaxies, cosmology, quantum gravity, the history of astronomy, and interactions between science, philosophy, and theology. On September 29, 1935, Pope Pius XI officially inaugurated the new headquarters of the Specola Vaticana at Castel Gandolfo. With new telescopes, a new astrophysical laboratory for spectrochemical analysis, and a young staff comprising Jesuit scientists, this inauguration marked the beginning of an intense period of scientific achievements at the Observatory. This anniversary book, featuring contributions from members of the current Observatory staff and adjunct scholars, will appeal to all with an interest in the history of the Specola Vaticana and its significance for astronomy.
A new collection of vibrant essays to inform, stimulate and inspire every nature lover. Times of darkness offer opportunities to reflect. In Mistletoe Winter, Roy Dennis offers his reflections on the natural world from the past year - from the welcome signs of change to the ongoing problems we are posing for nature, and what humankind can and must do about them. As in his companion volume, Cottongrass Summer, Roy Dennis balances his alarm at the crisis confronting the natural world with his own sense of optimism that new generations can make crucial changes for the future. One of our most prominent advocates for our planet and its species, he writes with insight and originality. This volume will provide inspiration and ideas for everyone who cares about our planet and its species.
The Cenozoic era began about 70 million years ago and still continues. In British Cenozoic Fossils 354 species from this period are classified and illustrated with accurate line drawings. This new edition has been fully revised and updated by John Todd, Curator of Molluscs in the Natural History Museum's Life Sciences Department, reflecting advances in our understanding of the fossil record over the past years. The book's 88-page identification section features those fossil animal and plant species that are most commonly found in Britain, from early plants, corals and fishes to gastropod and bivalve molluscs and the remains of mammals which lived in Britain during the Ice Ages. Each of the species is illustrated with at least one drawing, which is accompanied by details of where it can be found. There is a brief introduction to the subject, stratigraphical tables that show British Cenozoic rock formations, and a colour map of the distribution of Cenozoic strata.
In a divided world, empathy is not the solution, it is the problem. We think of empathy - the ability to feel the suffering of others for ourselves - as the ultimate source of all good behaviour. But while it inspires care and protection in personal relationships, it has the opposite effect in the wider world. As the latest research in psychology and neuroscience shows, we feel empathy most for those we find attractive and who seem similar to us and not at all for those who are different, distant or anonymous. Empathy therefore biases us in favour of individuals we know while numbing us to the plight of thousands. Guiding us expertly through the experiments, case studies and arguments on all sides, Paul Bloom ultimately shows that some of our worst decisions - in charity, child-raising, criminal justice, climate change and war - are motivated by this wolf in sheep's clothing. Brilliantly argued, urgent and humane, Against Empathy overturns widely held assumptions to reveal one of the most profound yet overlooked sources of human conflict.
This book sheds light on a little-known aspect of the Imperial family of Japan: For three generations, members of the family have devoted themselves to biological research. Emperor Showa (Hirohito) was an expert on hydrozoans and slime molds. His son, Emperor Akihito, is an ichthyologist specializing in gobioid fishes, and his research is highly respected in the field. Prince Akishino, Emperor Akihito's son, is known for his research on giant catfish and the domestication of fowl, while Prince Hitachi, Emperor Akihito's brother, has conducted research on cancer in animals. The book shows how they became interested in biology, how seriously they were committed to their research, what their main scientific contributions are, and how their achievements are valued by experts at home and abroad. To commemorate the 60-year reign of Emperor Showa and his longtime devotion to biology, the International Prize for Biology was founded in 1985. The prize seeks to recognize and encourage researches in basic biology. A list of winners and a summary of their research are presented in the last part of the book. The author, an eminent biologist who has given lectures to the Imperial Family, explains their research and tells the fascinating story of biology and the Imperial Family of Japan. The book is a valuable resource, not only for biology students and researchers, but also for historians and anyone interested in science and the Royal and Imperial families.
The way science is done has changed radically in recent years. Scientific research and institutions, which have long been characterized by passion, dedication and reliability, have increasingly less capacity for more ethical pursuits, and are pressed by hard market laws. From the vocation of a few, science has become the profession of many - possibly too many. These trends come with consequences and risks, such as the rise in fraud, plagiarism, and in particular the sheer volume of scientific publications, often of little relevance. The solution? A slow approach with more emphasis on quality rather than quantity that will help us to rediscover the essential role of the responsible scientist. This work is a critical review and assessment of present-day policies and behavior in scientific production and publication. It touches on the tumultuous growth of scientific journals, in parallel with the growth of self-declared scientists over the world. The author's own reflections and experiences help us to understand the mechanisms of contemporary science. Along with personal reminiscences of times past, the author investigates the loopholes and hoaxes of pretend journals and nonexistent congresses, so common today in the scientific arena. The book also discusses the problems of bibliometric indices, which have resulted in large part from the above distortions of scientific life.
'If there is one dominant myth about the world, one huge mistake we all make ... it is that we all go around assuming the world is much more of a planned place than it is.' From the industrial revolution and the rise of China, to urbanisation and the birth of bitcoin, Matt Ridley demolishes conventional assumptions that the great events and trends of our day are dictated by those on high. On the contrary, our most important achievements develop from the ground up. In this wide-ranging and erudite book, Matt Ridley brilliantly makes the case for evolution as the force that has shaped much of our culture, our minds, and that even now is shaping our future. As compelling as it is controversial, as authoritative as it is ambitious, Ridley's deeply thought-provoking book will change the way we think about the world and how it works.
Animal science is bizarre and wonderful. At the extreme end of zoology, psychologists are designing personality tests for dogs and logic problems for pigeons. They're giving fish spatial reasoning problems and asking cockatoos to keep a beat. Now, through dozens of interactive puzzles, IQ tests and quizzes, Are You Smarter Than a Chimpanzee? lets you test yourself against the best nature has to offer. So: are you more than a match for a marmoset? Or a bit of a birdbrain? Based on real, cutting-edge science and debunking common myths about animals, Are You Smarter Than a Chimpanzee? will make you question your assumptions about our place in the animal kingdom - and, finally, explain the real difference between dog-people and cat-people.
1856. Eighteen-year-old chemistry student William Perkin's experiment has gone horribly wrong. But the deep brown sludge his botched project has produced has an unexpected power: the power to dye everything it touches a brilliant purple. Perkin has discovered mauve, the world's first synthetic dye, bridging a gap between pure chemistry and industry which will change the world forever. From the fetching ribbons tying back the hair of every fashionable head in London to the laboratories in which scientists developed modern vaccines against cancer and malaria, Simon Garfield tells the story of how the colour purple became a sensation.
In Brain Wars, acclaimed neuroscientist Mario Beauregard reveals compelling new evidence set to provoke a major shift in our understanding of the mind-body debate: research showing that the mind and consciousness are transmitted and filtered through the brain--but are not generated by it.Following his boundary-breaking neuroscience book The Spiritual Brain: A Neuroscientist's Case for the Existence of the Soul, coauthored with Denyse O'Leary, Brain Wars makes a powerful and provocative case against the widely held view equating human beings to complex biological computers.Like Jeffrey M. Schwartz, Beauregard believes that consciousness is more than simply a physical process that takes place in the brain. And here, he presents the evidence to prove it. Brain Wars will revolutionize the way we think about thinking forever.
For almost forty years, Jane Dolinger traveled the world and wrote about her adventures, from the Amazon jungle to the sands of the Sahara. She produced eight books and more than a thousand articles between 1955 and 1995, and she also earned a reputation as a glamorous celebrity and model. Jane Dolinger was an anomaly in her time, a dynamic and attractive woman with an impressive literary talent, a woman who lived and documented a most unconventional and inspirational life. Sometimes controversial but always outstanding, Jane was a pioneer among women and writers. Here for the first time, her life and work are studied in a thoroughly researched yet entertaining literary biography. |
