Nearly everything making up what we call the "environment" of a plant has an infuence on the way it grows. Sunlight, te- perature, moisture contents of soil and atmosphere and vib- tions are all obvious examples of environmental components, and transient variations in their amount or intensity lead the plant to manifest more or less immediate responses. Small changes in carbon dioxide level in the atmosphere can even have effects, but these take a longer time to be registered - at least those that are visible, albeit at the microscopic level. Plants meet the challenges of the environment by means of acclimation. In this respect, plants are notable for the pl- ticity of their development. However, where morphological or physiological plasticity is no longer an option, the responses would be by means of adaptations as a result of genetic - lection or genetic "assimilation" (Waddington 1957). Thus, a feature that was once a facultative transient response to an environmental perturbation becomes a constitutive charac- ristic of plant structure or function. It is in this way that the environment continually molds the way in which plants de- lop, and also defnes the areas upon planet Earth where they will thrive.
As the world grieves over the catastrophic loss of humanity from the 26 December 2004 tsunami, we must resolve to learn from nature's lessons. This issue provides a framework and a set of tools to develop communities that are resilient to tsunami. This collection of papers represents a starting point on our new journey toward a safer world. The history of tsunami hazard mitigation tracks well with the history of destructive tsunamis in the United States. Following the 1946 Alaska g- erated tsunami that killed 173 people in Hawaii, the Paci?c Tsunami Warning Center was established in Hawaii by a predecessor agency to the National Oceanic and Atmospheric Administration (NOAA). Following the 1960 Chilean tsunami that killed 1,000 people in Chile, 61 in Hawaii, and 199 in Japan, the United States formed the Joint Tsunami Research E?ort (JTRE) and sta?ed the International Tsunami Information Center (ITIC) in Hawaii. JTRE was formed to conduct research on tsunamis while ITIC, sponsored by the United Nations, was formed to coordinate tsunami warning e?orts of the Paci?c Countries. Many research and mitigation e?orts were focused on the distant tsunami problem. Following the 1964 Alaskan t- nami that killed 117 in Alaska, 11 in California, and 4 in Oregon, the U. S. was confronted with the local tsunami problem. In response, the U. S. established the Alaska Tsunami Warning Center in Palmer, Alaska. In 1992, a Ms 7.
From 1965-1968, I held an Agricultural Research Council Research Fellowship at Christ's College, Cambridge. Later in 1981, when I was a Visiting Fellow in the Department of Biochemistry, University of Cambridge and renewed my contacts with Christ's College, my friend and colleague David Coombe, a Fellow of Christ's College, informed me that a collection of letters of Charles Darwin had just been - covered in the Library storeroom, underneath the College. I had always maintained an interest in Charles Darwin, from the early age of thirteen, when I had rst read his books, with I might say some dif culty! This collection was the 155 letters of Charles Darwin to his second cousin William Darwin Fox, which had been given in trust to the College, in 1909, by members of the Fox family at the time of the Darwin Centenary celebrations. I was allowed access to these 155 letters and at that time made my own tr- scriptions. It seemed to me that this was a magni cent account of the lives of two naturalists of the nineteenth century, starting at the time that they were at Christ's together, in 1828, and going to 1880 when W D Fox died - just two years short of the death of Charles Darwin in 1882. Of course this valuable resource had not gone unnoticed before. Darwin's son, Francis Darwin had been given the letters in the 1880s, when he was preparing his Life and Letters of Charles Darwin in 3 volumes.
The human brain has some capabilities that the brains of other animals lack. It is to these distinctive capabilities that our species owes its dominant position. Other animals have stronger muscles or sharper claws, but we have cleverer brains. If machine brains one day come to surpass human brains in general intelligence, then this new superintelligence could become very powerful. As the fate of the gorillas now depends more on us humans than on the gorillas themselves, so the fate of our species then would come to depend on the actions of the machine superintelligence. But we have one advantage: we get to make the first move. Will it be possible to construct a seed AI or otherwise to engineer initial conditions so as to make an intelligence explosion survivable? How could one achieve a controlled detonation? To get closer to an answer to this question, we must make our way through a fascinating landscape of topics and considerations. Read the book and learn about oracles, genies, singletons; about boxing methods, tripwires, and mind crime; about humanity's cosmic endowment and differential technological development; indirect normativity, instrumental convergence, whole brain emulation and technology couplings; Malthusian economics and dystopian evolution; artificial intelligence, and biological cognitive enhancement, and collective intelligence. This profoundly ambitious and original book picks its way carefully through a vast tract of forbiddingly difficult intellectual terrain. Yet the writing is so lucid that it somehow makes it all seem easy. After an utterly engrossing journey that takes us to the frontiers of thinking about the human condition and the future of intelligent life, we find in Nick Bostrom's work nothing less than a reconceptualization of the essential task of our time.
'Sarma's book may be the most important work on education written this century' - Skeptic As the head of Open Learning at MIT, Sanjay Sarma has a daunting job description: to fling open the doors of the MIT experience for the benefit of the wider world. But if you're going to undertake such an ambitious project, you must first ask: How exactly does learning work? What conditions are most conducive? Are our traditional classroom methods - lecture, homework, test, repeat - actually effective? And if not, which techniques are? Grasp takes readers across multiple frontiers, from fundamental neuroscience to cognitive psychology and beyond, as it explores the future of learning. For instance: * Scientists are studying the role of forgetting, exposing it not as a simple failure of memory but a critical weapon in our learning arsenal * New developments in neuroimaging are helping us understand how reading works in the brain. It's become possible to identify children who might benefit from specialised dyslexia interventions - before they learn to read * Many schools have begun converting to flipped classrooms, in which you watch a lesson at home, then do your 'homework' in class Along the way, Sarma debunks long-held views such as the noxious idea of 'learning styles,' while equipping readers with a set of practical tools for absorbing and retaining information across a lifetime of learning. He presents a vision for learning that's more inclusive and democratic - revealing a world bursting with powerful learners, just waiting for the chance they deserve. Drawing from the author's experience as an educator and the work of researchers and educational innovators at MIT and beyond, Grasp offers scientific and practical insight, promising not just to inform and entertain readers but to open their minds.
The European People's Party, the largest political party in Europe, has roots that run deep in history. Founded in 1976 as a Christian Democratic federation, the European People's Party is now a strong centre-right movement and a leading European political family. It has member parties in almost all European countries, and it is very well represented in the institutions of the European Union. This book tells the story of the European People's Party: why it was founded, how it is currently organised and what its guiding ideas, values and principles are. It gives an up-to-date account of the party's contribution to European integration, its work with its member parties and its central role in organising the centre-right in Europe. Above all, this book is for everyone who wants to know what a European-level political party looks like, how it is structured and how it acts.
Electricity is all around us: cars, telephones, computers, lights -- the modern world runs entirely on electrons. But what are electrons? How do they behave? How do we control them? This book will show you how to build a battery, detect static electricity and construct a basic current meter, all using common items from your kitchen. Along the way you'll learn about the meaning of "voltage" and "current," what makes an LED work and the difference between AC and DC. The last chapter uses transistors -- the basic building blocks of every computer -- for lots of interesting experiments. With plenty of colorful illustrations, historical stories and an easy, accessible style, "A Kitchen Course in Electricity and Magnetism" will be a great start for budding and amateur scientists who want to learn more about how the world works.
Fifty thousand years ago--merely a blip in evolutionary time--our "Homo sapiens" ancestors were competing for existence with several other human species, just as their precursors had done for millions of years. Yet something about our species distinguished it from the pack, and ultimately led to its survival while the rest became extinct. Just what was it that allowed "Homo sapiens" to become masters of the planet? Ian Tattersall, curator emeritus at the American Museum of Natural History, takes us deep into the fossil record to uncover what made humans so special. Surveying a vast field from initial bipedality to language and intelligence, Tattersall argues that "Homo sapiens" acquired a winning combination of traits that was not the result of long-term evolutionary refinement. Instead, the final result emerged quickly, shocking our world and changing it forever.
Life is a diverse and ubiquitous phenomenon on Earth, characterized by fundamental features distinguishing living bodies from nonliving material. Yet it is also so complex that it has long defied precise definition. This book from a seasoned biologist offers new insights into the nature of life by illuminating a fascinating architecture of dualities inherent in its existence and propagation. Life is connected with individual living beings, yet it is also a collective and inherently global phenomenon of the material world. It embodies a dual existence of cycles of phenotypic life, and their unseen driver - an uninterrupted march of genetic information whose collective immortality is guaranteed by individual mortality. Although evolution propagates and tunes species of organisms, the beings produced can be regarded merely as tools for the survival and cloning of genomes written in an unchanging code. What are the physical versus informational bases and driving forces of life, and how do they unite as an integrated system? What does time mean for individuals, life on the global scale, and the underlying information? This accessible examination of principles and evidence shows that a network of dualities lies at the heart of biological puzzles that have engaged the human mind for millennia.
Beyond Human is an informative and accessible guide for all those interested in the developing sciences of genetic engineering, bio printing and human cloning. Illustrating the ideas with reference to well-known science fiction films and novels, the author provides a unique insight into and understanding of how genetic manipulation, cloning, and other novel bio-technologies will one day allow us to redesign our species. It also addresses the legitimate concerns about playing God, while at the same time embracing the positive aspects of the scientific trajectory that will lead to our transhuman future."

This book introduces the basic techniques and methods traditionally used in speaking about science to the public. The public often has a very different perception and understanding of science, and this must be taken into account when communicating with the public. This volume covers methods of scientific discourse, oral communication, preparation of the presentation, techniques and use of visual resources, and exercises for perfecting the technique of speaking in public about science. "Speaking in Public About Science: A Quick Guide for the Preparation of Good Lectures, Seminars, and Scientific Presentations" is a concise yet comprehensive resource that will be of value to beginners and senior scholars and researchers.
Our Human Story is a guide to our fossil relatives, from what may be the earliest hominins such as Sahelanthropus, dating back six to seven million years, through to our own species, Homo sapiens. Over the past 25 years there has been an explosion of species' names in the story of human evolution, due both to new discoveries and to a growing understanding of the diversity that existed in the past. Drawing on this new information, as well as their own considerable expertise and practical experience, Louise Humphrey and Chris Stringer explain in clear and accessible terms what each of the key species represents and how it contributes to our knowledge of human evolution.

Humans are the most inquisitive, emotional, imaginative, aggressive and baffling animals on the planet. But how well do we really know ourselves? How to Be Animal offers a radical take on what it means to be human and argues that at the heart of our psychology is a profound struggle with being animal. Tracing the history of this thinking through to its far-reaching effects on our lives, and drawing on a range of disciplines, Challenger proposes that being an animal is a process, beautiful and unpredictable, and that we have a chance to tell ourselves a new story; to realise that if we matter, so does everything else.
"I read this wide-ranging and thoughtful book while sitting on the banks of the Ganges near Varanasi-it's a river already badly polluted, and now threatened by the melting of the loss of the glaciers at its source to global warming. Four hundred million people depend on it, and there's no backup plan. As Steven Solomon makes clear, the same is true the world over; this volume will give you the background to understand the forces that will drive much of 21st century history." -Bill McKibben In Water, esteemed journalist Steven Solomon describes a terrifying-and all too real-world in which access to fresh water has replaced oil as the primary cause of global conflicts that increasingly emanate from drought-ridden, overpopulated areas of the world. Meticulously researched and undeniably prescient, Water is a stunningly clear-eyed action statement on what Robert F Kennedy, Jr. calls "the biggest environmental and political challenge of our time."
New fundamental forces of Nature? New forms of "dark'' energy?
Signals from epochs preceding the Big Bang? Is our space-time
unique? Only a joint study of the three topics examined in this
book - gravity, strings and particles - may provide answers to
these questions. Such a study may also provide the key to solving
one of the most fascinating mysteries of modern science, namely:
Besides time and the three spatial dimensions, how many other
dimensions exist in our universe? "
The human body is a remarkable machine that goes through extraordinary measures to fight disease. However, it has always been a challenge for the curious general reader to find a concise and entertaining explanation of the biological processes that combat illness. Dying to Live addresses this need. Written in a clear and accessible style, this book gives an up-to-date account of the inner workings of our immune systems. Aimed at the lay reader, it examines important areas of medical science such as fever, AIDS and cancer. The book highlights the role of the mother in protecting the developing child during and after pregnancy and draws our attention to the changes in our immune system throughout life. The author looks at vaccinations and how pathogens evade their effects and considers the impact of lifestyle, stress, exercise, dietary, and hereditary factors on our ability to fight disease. The theme central to the book, from which the title derives, is the idea that in the war against disease our bodies sacrifice millions of cells--antibodies and other specialized elements of the immune system. Only by pitting these immune cells against infectious agents can we continue to survive. This current and enlightening book will interest anyone who has ever wondered what is happening in our bodies when we get ill and how we recover. An expert on immunology in general and the thymus gland in particular, Marion Kendall has edited several books and published over 100 articles on these subjects. Dr. Kendall has lectured extensively in Europe, Canada, and the United States.
THE DEFINITIVE GUIDE TO ALCOHOL AND YOUR HEALTH Alcohol - a simple molecule that can induce so much pleasure and pain at the same time... As the most harmful drug in the UK, it has a profound and wide-reaching impact on our health and on society at large. Drink? is the first book of its kind, written by a scientist and rooted in 40 years of medical research and hands-on experience treating patients. Professor David Nutt cuts through the noise to explain the long- and short-term effects of alcohol, makes complex science digestible and takes readers through its journey inside the body and brain from the very first sip. Drink? holds the key to all the questions you want to know the answers to, covering mental health, sleep, hormones, fertility and addiction. It sheds light on what 'responsible drinking' truly means and equips us with the essential knowledge we all need to make rational, informed decisions about our consumption now and in the future.
Astronomers have successfully observed a great deal of the Universe's history, from recording the afterglow of the Big Bang to imaging thousands of galaxies, and even to visualising an actual black hole. There's a lot for astronomers to be smug about. But when it comes to understanding how the Universe began and grew up we are literally in the dark ages. In effect, we are missing the first one billion years from the timeline of the Universe. This brief but far-reaching period in the Universe's history, known to astrophysicists as the 'Epoch of Reionisation', represents the start of the cosmos as we experience it today. The time when the very first stars burst into life, when darkness gave way to light. After hundreds of millions of years of dark, uneventful expansion, one by the one these stars suddenly came into being. This was the point at which the chaos of the Big Bang first began to yield to the order of galaxies, black holes and stars, kick-starting the pathway to planets, to comets, to moons, and to life itself. Incorporating the very latest research into this branch of astrophysics, this book sheds light on this time of darkness, telling the story of these first stars, hundreds of times the size of the Sun and a million times brighter, lonely giants that lived fast and died young in powerful explosions that seeded the Universe with the heavy elements that we are made of. Emma Chapman tells us how these stars formed, why they were so unusual, and what they can teach us about the Universe today. She also offers a first-hand look at the immense telescopes about to come on line to peer into the past, searching for the echoes and footprints of these stars, to take this period in the Universe's history from the realm of theoretical physics towards the wonder of observational astronomy.
FULLY UPDATED FOR 2019 We cannot live without water. But with 7.5 billion people competing for this single unevenly-distributed resource, the planet is drying up. In When the Rivers Run Dry, Fred Pearce explores the growing world water crisis, from Kent to Kenya. His powerful reportage takes us to places where waterways are turning to sand before they reach the ocean; where fields are parched and crops no longer grow; where once fertile ground has turned to desert; where wars are fought over access to water and cultures are dying out. But he offers us hope for the future - if we can radically revolutionise the way we treat water, and take personal responsibility for the water we use. This landmark work, from a respected and accomplished scientist, will transform the way we view the water in our reservoirs and rivers, and change the way we treat the water in our taps.
Science is the world's new religion" but what happens when it goes terribly wrong? An innocent young black man is convicted of rape and sent to prison for 25 years on the basis of 'infallible' DNA evidence - which turns out to be completely bogus. A long-distance runner's Parkinson's Disease is treated with revolutionary neuroscience techniques, which leave a foetus growing in his brain. A study into why children stutter ends up ruining their lives when scientists deliberately introduce speech impediments, and, to their horror, find they are permanent. British neuroscientist Simon LeVay explains how elementary mistakes, miscaculations and simple bad science sometimes lead to death (when anthrax spores escape from a lab, or a nuclear plant explodes) and other times to expensive farce (when a tiny data error sends a space probe hurtling to oblivion, or when an 'impossible' hurricane wreaks havoc across the UK). Baboons on ecstasy, death-by-volcano and the failure of gene therapy to perform as advertised also feature in this authoritative and entertaining study of the limitations of science.
The "Rudolf Moessbauer Story" recounts the history of the discovery of the "Moessbauer Effect" in 1958 by Rudolf Moessbauer as a graduate student of Heinz Maier-Leibnitz for which he received the Nobel Prize in 1961 when he was 32 years old. The development of numerous applications of the Moessbauer Effect in many fields of sciences , such as physics, chemistry, biology and medicine is reviewed by experts who contributed to this wide spread research. In 1978 Moessbauer focused his research interest on a new field "Neutrino Oscillations" and later on the study of the properties of the neutrinos emitted by the sun.
An insider's view on bringing extinct species back to life Could extinct species, like mammoths and passenger pigeons, be brought back to life? In How to Clone a Mammoth, Beth Shapiro, an evolutionary biologist and pioneer in ancient DNA research, addresses this intriguing question by walking readers through the astonishing and controversial process of de-extinction. From deciding which species should be restored to anticipating how revived populations might be overseen in the wild, Shapiro vividly explores the extraordinary cutting-edge science that is being used to resurrect the past. Considering de-extinction's practical benefits and ethical challenges, Shapiro argues that the overarching goal should be the revitalization and stabilization of contemporary ecosystems. Looking at the very real and compelling science behind an idea once seen as science fiction, How to Clone a Mammoth demonstrates how de-extinction will redefine conservation's future.
More than just coincidence connects a Tate & Lyle lawsuit and artificial sweetener to Jamaican-born Chemist Bert Fraser-Reid. From his first experience of Chemistry through his diabetic father, to his determination and drive as a Chemistry student in Canada, Fraser-Reid weaves a remarkable tale integrating science, law and autobiographical anecdotes. This book arises from the lawsuit brought by Tate & Lyle against companies accused of infringing its patents for sucralose, the sweet ingredient in the artificial sweetener SPLENDA which is made by chlorinating sugar. From a 1958 undergraduate intern witnessing the pioneering experiments on sugar chlorination, to being the 1991 recipient of the world's premiere prize for carbohydrate chemistry, Fraser-Reid was groomed for his role as expert witness in the mentioned lawsuit. Nevertheless, it seems more than his career links Fraser-Reid to the case. |
