Arguing About Bioethics is a fresh and exciting collection of essential readings in bioethics, offering a comprehensive introduction to and overview of the field. Influential contributions from established philosophers and bioethicists, such as Peter Singer, Thomas Nagel, Judith Jarvis Thomson and Michael Sandel, are combined with the best recent work in the subject.

Organised into clear sections, readings have been chosen that engage with one another, and often take opposing views on the same question, helping students get to grips with the key areas of debate. All the core issues in bioethics are covered, alongside new controversies that are emerging in the field, including:

• embryo research
• selecting children and enhancing humans
• human cloning
• using animals for medical purposes
• organ donation
• consent and autonomy
• public health ethics
• resource allocation
• developing world bioethics
• assisted suicide.

Each extract selected is clear, stimulating and free from unnecessary jargon. The editor 's accessible and engaging section introductions make Arguing About Bioethics ideal for those studying bioethics for the first time, while more advanced readers will be challenged by the rigorous and thought-provoking arguments presented in the readings.

Public health is about taking collective action to protect and promote the health of populations. For example, vaccination and screening programmes help avoid or ameliorate diseases; health education and promotion help make people healthier. Public health is underpinned by research, including epidemiology. Public health research is enormously beneficial but also creates ethical issues. Some are familiar from standard research ethics, but with a public health 'twist'. For example, what sort of informed consent is required when research involves large data sets used by epidemiologists? Other issues are distinctive to public health research: should ethical restrictions on research be lifted during public health emergencies, for example? This book analyses current ethical issues in public health research. Rigorous discussions are informed by insights from standard research ethics, from philosophy and bioethics, and from the author's related research and experience as Chair of Public Health England's Research Governance Review Group. An overarching theme of the book is the trade-off between one's right to decide to participate in public health research versus the communal duty to do so.

The principles of stratigraphic paleobiology can be readily applied to the nonmarine fossil record. Consistent spatial and temporal patterns of accommodation and sedimentation in sedimentary basins are an important control on stratigraphic architecture. Temperature and precipitation covary with elevation, causing significant variation in community composition, and changes in base level cause elevation to undergo predictable changes. These principles lead to eight sets of hypotheses about the nonmarine fossil record. Three relate to long-term and cyclical patterns in the preservation of major fossil groups and their taphonomy, as well as the occurrence of fossil concentrations. The remaining hypotheses relate to the widespread occurrence of elevation-correlated gradients in community composition, long-term and cyclical trends in these communities, and the stratigraphic position of abrupt changes in community composition. Testing of these hypotheses makes the stratigraphic paleobiology of nonmarine systems a promising area of investigation.
