The Cutting-Edge Technology series zeros in on advances in engineering that have changed our world and continue to do so. Each book looks at a particular invention, from its conceptualization and development to its practical uses today and potential applications in the future. In addition to the main text, which is well organized and informative, each double-page spread includes colorful design elements such as photos, sidebars, and the occasional diagram. "Cutting-edge" can mean controversial, but that's not always the case here, depending on the topic and the writer's viewpoint. GMOs offers a careful balance of the technology's promise for beneficial changes that can save lives with legitimate concerns about possible consequences, such as harm to the environment. Useful books for updating the engineering shelves.
