Nutrition is a topic of wide interest and importance. In spite of growing understanding of the underlying biochemistry, and health campaigns such as "five-a-day", increasing obesity and reported food allergies and eating disorders, as well as the widely advertised "supposed" benefits of food supplements mean that a clear explanation of the basic principles of a healthy diet are vital. In this Very Short Introduction, David Bender explains the basic elements of food, the balance between energy intake and exercise, the problems of over- and under-nutrition, and raises the question of safety of nutritional supplements.

Teeth are amazing - the product of half a billion years of evolution. They provide fuel for the body by breaking apart other living things; and they must do it again and again over a lifetime without themselves being broken in the process. In this Very Short Introduction, Peter S. Ungar, an award-winning author and leading scientist, presents the story of teeth. Ungar outlines the key concepts, including insights into the origin of teeth and theirevolution. Considering why teeth are important, he describes how they are made, and how they work, including their fundamental importance in the fossil record. Ungar finishes with a review of mammal teeth, looking athow they evolved and how recent changes to our diet are now affecting dental health.

Radioactivity - the breakdown of unstable atomic nuclei, releasing radiation - is a fundamental process in nature, and used to provide important applications in science, medicine, and energy production. But it remains misunderstood and feared. In this Very Short Introduction, Claudio Tuniz explains the nature and mechanisms of radioactivity.

Corruption is one of the biggest issues facing the contemporary international community. This volume notes that corruption is as old as humanity itself, and then considers why the international community has only highlighted it as a problem in the past two decades. It explores the phenomenon from several different perspectives, from the cultural differences affecting how corruption is defined, its impact, its various causes, and the possible remedies.

Agriculture, one of the oldest human occupations, is practised all over the world, using techniques ranging from the profoundly traditional to the most scientifically advanced. Without it we would starve. Yet how many of us understand what is happening in the fields that we see as we drive through the countryside? How often do we think about the origins of the food in our trolley? In this Very Short Introduction Paul Brassley and Richard Soffe explain what farmers do and why they do it. Beginning with the most basic resource, the soil, they show why it is important, and how farmers can increase its productivity, before turning to the plants and animals that grow on it, and tracing the connections between their biology and the various ways in which farmers work with them. The authors conclude by looking at some of the controversial issues facing contemporary agriculture: its sustainability; its impact on wildlife and landscape; issues of animal welfare; and the affect of climate change and the development of genetically modified organisms on farmers.

Today it is usually not long before a problem gets expressed as a human rights issue. Indeed, human rights law continues to gain increasing attention internationally, and must move quickly in order to keep up with a social world that changes so rapidly. This Very Short Introduction, in its second edition, brings the issue of human rights up to date, considering the current controversies surrounding the movement. Discussing torture and arbitrary detention in the context of counter terrorism, Andrew Clapham also considers new challenges to human rights in the context of privacy, equality and the right to health. Looking at the philosophical justification for rights, the historical origins of human rights and how they are formed in law, Clapham explains what our human rights actually are, what they might be, and where the human rights movement is heading.

Rocks, more than anything else, underpin our lives. They make up the solid structure of the Earth and of other rocky planets, and are present at the cores of gas giant planets. We live on the rocky surface of the planet, grow our food on weathered debris derived from rocks, and we obtain nearly all of the raw materials with which we found our civilization from rocks. From the Earth's crust to building bricks, rocks contain our sense of planetary history, and are a guide to our future. In this Very Short Introduction Jan Zalsiewicz looks at the nature and variety of rocks, and the processes by which they are formed. Starting from the origin of rocks and their key role in the formation of the Earth, he considers what we know about the deep rocks of the mantle and core, and what rocks can tell us about the evolution of the Earth, and looks at those found in outer space and on other planets.

The importance of the oceans to life on Earth cannot be overstated. Liquid water covers more than 70% of our planet's surface and, in past geological time, has spread over 85%. Life on Earth began in the oceans over 3.5 billion years ago and remained there for the great majority of that time. Today the seas still provide 99% of habitable living space, the largest repository of biomass, and holds the greatest number of undiscovered species on the planet. Our oceans are vital for the regulation of climate, and with global warming and decreasing land area, they have become increasingly important as the source of food, energy in the form of oil and gas, and for their mineral wealth. Oceans also form a key part of the biogeochemical cycles of carbon, nitrogen, and other elements critical to life. Nutrients in upwelling areas are spread by ocean currents, and the plankton of the seas supports a wealth of wildlife. In this Very Short Introduction Dorrik Stow analyses these most important components of our blue planet and considers their relationship with, and exploitation by, humans. He shows how the oceans are an essential resource to our overpopulated world, and discusses why exploration and greater scientific understanding of the oceans, their chemistry, and their mineral wealth are now a high priority. Stow also explores what we know of how oceans originate, and evolve and change; the shape of the seafloor and nature of its cover; the physical processes that stir the waters and mix such a rich chemical broth; and the inseparable link between oceans and climate. As polar ice melts and sea-levels rise, countless millions who have made their homes on low-lying lands close to the sea are threatened. As scientific exploration of the seas gathers pace, the new knowledge gained of the ocean-Earth systems and their interaction with the human environment is vital to our understanding of how we can preserve these ultimately fragile environments.

Le rabat de la couverture indique : Blood is a vital fluid with a profound cultural and historical significance. Long considered the essence of life, blood pumps through our language and religion, and is a major diagnostic tool in the doctor's armoury. This Very Short Introduction explores early views of blood, our modern understanding of its nature and components, and future possibilities, such as artificial blood. Chris Cooper gets to the heart of this fascinating topic, covering the basic biology of blood, and the role of blood transfusions, blood tests, and the treatment of blood-borne diseases in modern medicine.
