VOYAThe Seiples combine their backgrounds and education (hers in library science and science publishing, his in chemistry) in creating this very readable, up-to-date book on biotechnology. The first two chapters introduce biotechnology's history and explain the basic concepts of genes, DNA, and cloning. Each subsequent chapter looks at a new trend or development in biotechnology research. General topics, such as genetically modified foods and stem-cell research, are covered, and fascinating specific examples including the frog mutations in Minnesota in the 1990s or the possibilities of vaccines being delivered in foods in the future bring these issues to life. Each topic is carefully explained and frequent color photos and illustrations help depict the concepts. Care is taken in each chapter to present both sides of the issue; there are frequent quotes from those who oppose animal research as well as examples of how biotechnology has helped humans. Furthermore the final chapter looks at organizations who oppose aspects of biotechnology. This balanced approach to the topic makes the book a great discussion starter for classrooms or a great resource for research at the middle school level. The attractive cover and intriguing title will even snag some casual readers. It is a nice addition to collections in need of an update on the fast-developing field of biotechnology.
