Spanning the entire spectrum of life science research, the Encyclopedia features more than 3,000 specially commissioned and peer-reviewed articles. These concentrate primarily on the molecular and cellular life sciences, including biochemical topics, methods and techniques. Applied areas of science are also included on a selective basis, as are biographies and general interest articles on ethics and the history of science. Since the acquisition of ELS from NPG in 2004, Wiley has been adding both new and updated articles to keep readers up-to-date with the relentlessly evolving nature of life sciences, carefully commissioning in areas that have been particularly dynamic on the advice of a specialist board of scientific editors. Accordingly, in this six-volume work, we have published an additional 650 new and updated peer-reviewed articles that compliment the original print volume set. By completing the original set with these new articles, the reader is kept up-to-date with research across the life sciences in one complete print product. Aimed at researchers, students and teachers, articles provide comprehensive and authoritative coverage, written by leaders in the field. Colour illustrations and tables accompany articles, with appendix and glossary material providing essential information for the non-specialist, including biochemical and taxonomic information, acronyms, synonyms, units and other technical data. Importantly, all articles have been peer-reviewed to ensure a balanced representation of the literature. Articles are divided into three different categories indicating their level of complexity: Introductory, Advanced and Keynote. Introductory articles have been written primarily for undergraduate and non--specialists requiring the basic concepts of a particular subject. Advanced articles provide a more detailed discussion of specialist subjects, equivalent to that found in graduate level texts. Keynote articles provide a platform for debate where controversial issues and 'hot topics' can be discussed. The coverage includes topics, such as: Biochemistry; Cell Biology; Developmental Biology; Ecology; Evolution and Diversity of Life; Functional and Comparative Morphology; Genetics and Disease; Genetics and Molecular Biology; Immunology; Microbiology; Neuroscience; Plant Science; Science and Society; Structural Biology; and, Virology. Don't miss this great opportunity to own the leading resource in the life sciences.
