(3) K-3 Illustrated by Lin. When scientist Tu Youyou had tuberculosis as a child, she was given western antibiotics in the hospital and traditional herbs at home. Grounded by that experience, Youyou tapped traditional Chinese medicine when she was called to lead a research group to cure malaria. Her 1971 discovery, a malaria-killing extract of qinghao (sweet wormwood), eventually became the standard treatment worldwide and earned her a Nobel Prize in 2015. The straightforward text is closely focused on Youyou's discovery and celebrates her persistence, problem-solving ability, and teamwork. Gentle cartoon illustrations with rounded figures and stylized faces show the earnest research team in their laboratory. A timeline, bibliography, author's note, and a step-by-step explanation of the scientific method conclude the book.
