In this exploration of the concept of the gene, Jonathan Slack looks at the discovery, nature, and role of genes in both evolution and development. Explaining the nature of genetic variation in the human population, how hereditary factors were identified as molecules of DNA, and how certain specific mutations can lead to disease, Slack highlights how DNA variants are used to trace human ancestry and migration, and can also used by forensic scientists to identify individuals in crime. He also explores issues such as the role of genetic heritability and IQ as well as the changes that occur in the genes of populations during evolution. An ideal guide for anyone curious about what genes are and how genetics can be put to use, this Very Short Introduction demonstrates the ways in which the gene concept has been understood and used by molecular biologists, population biologists, and social scientists around the world.

Are we born with our fears or do we learn them? Why do our fears persist? What purpose does anxiety serve? In this Very Short Introduction we discover what anxiety is, what causes it, and how it can be treated. Looking at six major anxiety disorders, the authors introduce us to this most ubiquitous and essential of emotions.

How animals behave is crucial to their survival and reproduction. The application of new molecular tools such as DNA fingerprinting and genomics is causing a revolution in the study of animal behaviour, while developments in computing and image analysis allow us to investigate behaviour in ways never previously possible. By combining these with the traditional methods of observation and experiments, we are now learning more about animal behaviour than ever before. In this Very Short Introduction Tristram D. Wyatt discusses how animal behaviour has evolved, how behaviours develop in each individual (considering the interplay of genes, epigenetics, and experience), how we can understand animal societies, and how we can explain collective behaviour such as swirling flocks of starlings. Using lab and field studies from across the whole animal kingdom, he looks at mammals, butterflies, honeybees, fish, and birds, analysing what drives behaviour, and exploring instinct, learning, and culture. Looking more widely at behavioural ecology, he also considers some aspects of human behaviour.

"A concise account of what we know about development discusses the first vital steps of growth and explores one of the liveliest areas of scientific research."--P. [2] of cover.

Molecular Biology is the story of the molecules of life, their relationships, and how these interactions are controlled. It is an expanding field in life sciences, and its applications are wide and growing. We can now harness the power of molecular biology to treat diseases, solve crimes, map human history, and produce genetically modified organisms and crops, and these applications have sparked a multitude of fascinating legal and ethical debates. In this Very Short Introduction, Aysha Divan and Janice Royds examine the history, present, and future of Molecular Biology. Starting with the building blocks established by Darwin, Wallace and Mendel, and the discovery of the structure of DNA in 1953, they consider the wide range of applications for Molecular Biology today, including the development of new drugs, and forensic science. They also look forward to two key areas of evolving research such as personalised medicine and synthetic biology.

People value their powers of thinking and most of us are interested in why some people seem to drive a highly tuned Rolls Royce brain while others potter along with a merely serviceable Ford Fiesta. This Very Short Introduction describes what psychologists have discovered about how and why people differ in their thinking powers. The book takes readers from no knowledge about the science of human intelligence to a stage where they are able to make judgements for themselves about some of the key questions about human mental ability differences. Each chapter deals with a central issue that is both scientifically lively and of considerable general interest, and is structured around a diagram which is explained in the course of the chapter. The issues discussed include whether there are several different types of intelligence, whether intelligence differences are caused by genes or the environment, the biological basis of intelligence differences, and whether intelligence declines or increases as we grow older.

"How does the brain work? Michael O'Shea provides an accessible introduction to the key questions and current state of brain research, and shows that, though we know a surprising amount, we are still far from having a complete understanding. The topics he discusses range from how we sense things and how memories are stored, to the evolution of brains and nervous systems from primitive organisms, as well as altered mental states, brain-computer hybrids, and the future of brain research."--BOOK JACKET.

The topic of stem cells has been very high profile in the media in recent years. There is much public interest in stem cells but also much confusion and misinformation, with some companies already offering 'stem cell products' and bogus 'stem cell therapies'. In this Very Short Introduction, Jonathan Slack introduces stem cells; what they are, what scientists do with them, what stem cell therapies are available today, and how they might be used in future. Despite important advances, clinical applications of stem cells are still in their infancy. Most real stem cell therapy today is some form of bone marrow transplantation. Slack introduces stem cells by explaining the difference between embryonic stem cells, which exist only in laboratory cultures, and tissue-specific stem cells, which exist in our bodies. Embryonic stem cells can become any cell type in the body, so diseases that may in future be treated by functional cells derived from these sorts of stem cell include diabetes, Parkinson's disease, heart disease, and spinal trauma. He then goes on to discuss the properties of tissue-specific stem cells and the important technique of bone marrow transplantation. Slack concludes by analysing how medical innovation has occurred in this area in the past, and draws out some of the lessons for the development of new therapies in the future.

In recent decades we have come to realize that the microbial world is hugely diverse, and can be found in the most extreme environments. Fungi, single-celled protists, bacteria, archaea, and the vast array of viruses and sub-viral particles far outnumber plants and animals. Microbes, we now know, play a critical role in ecosystems, in the chemistry of atmosphere and oceans, and within our bodies. The field of microbiology, armed with new techniques from molecular biology, is now one of the most vibrant in the life sciences. In this Very Short Introduction Nicholas P. Money explores not only the traditional methods of microscopy and laboratory culture but also the modern techniques of genetic detection and DNA sequencing, genomic analysis, and genetic manipulation. In turn he demonstrates how advances in microbiology have had a tremendous impact on the areas of medicine, agriculture, and biotechnology.
