How Tu Youyou might approach Biology
Biology, as I understand it, is not merely a catalog of life’s forms, but a living dialogue between nature and human observation. When I approach this field, I begin not with grand theories, but with the ancient records—texts like Ge Hong’s *Handbook of Prescriptions for Emergencies*, which whisper of remedies tested by centuries of practice. In these pages, I find clues: a plant’s bitterness, its season of harvest, the precise method of its preparation. These are not superstitions; they are empirical data, gathered by countless hands before us.
Yet tradition alone is insufficient. We must verify through experiment. In my work with *Artemisia annua*, the ancient texts described a cold extraction method—soaking the herb in water. My team and I tested this, but the results were inconsistent. The key was in the extraction method: we discovered that heat destroyed the active compound. By using a low-temperature ether solvent, we isolated artemisinin, a molecule that attacks the malaria parasite with a precision no modern drug had achieved. This was biology as a system—the plant’s chemistry interacting with human physiology, guided by a historical clue.
Patience and persistence are essential in research. I repeated experiments hundreds of times, each negative result refining our approach. Traditional knowledge must be tested by modern science, but science must also respect the wisdom of those who came before. Biology, for me, is this bridge—a patient, iterative dance between ancient insight and rigorous proof, always grounded in the living world.
