Very Short Introductions: Brilliant, Sharp, Inspiring 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. By 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 be 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. This second edition has been fully updated and contains new sections on the CRISPR method for targeted genetic modification, on DNA profiling, and developments in our understanding of human ancestry using ancient DNA.

The topic of stem cells has a high profile in the media. We've made important advances in our scientific understanding, but despite this the clinical applications of stem cells are still in their infancy and most real stem cell therapy carried out today is some form of bone marrow transplantation. At the same time, a scandalous spread of unproven stem cell treatments by private clinics represents a serious problem, with treatments being offered which are backed by limited scientific rationale, and which are at best ineffective, and at worse harmful. This Very Short Introduction introduces stem cells, exploring what they are, and what scientists do with them. Introducing the different types of stem cells, Jonathan Slack explains how they can be used to treat diseases such as retinal degeneration, diabetes, Parkinson's disease, heart disease, and spinal trauma. He also discusses the important technique of bone marrow transplantation and some other types of current stem cell therapy, used for the treatment of blindness and of severe burns. Slack warns against fake stem cell treatments and discusses how to distinguish real from fake treatments. He also describes the latest scientific progress in the field, and looks forward to what we can expect to happen in the next few years Very Short Introductions: Brilliant, Sharp, Inspiring ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.
