Who better to create the Edge of Medicine series (6 titles) than the Mayo Clinic? Each volume immediately grabs the reader's attention through an opening, high-interest account of a recent medical breakthrough. Next, individual chapters chronologically introduce scientific discoveries that have collectively contributed to today's medical practices and ongoing research. The text is clear and accompanied by photos, reproductions, models, and diagrams, but advanced readers may benefit more from the included details and higher-level concepts. Genetic Breakthroughs describes the discoveries of genes, DNA, and chromosomes; how these biological building blocks can link to disease; and how gene mapping and editing are being used to treat individuals with genetic disorders. Spotlights on Mayo Clinic scientists and concluding time lines offer more context to curious readers.
