In this episode of FYI, Brett Winton and Nemo Marjanovic sit down with Professor Thomas Hartung, MD-PhD, a leading expert in biomedical innovation at Johns Hopkins Bloomberg School of Public Health. They explore how human organoids—3D organ proxies—are revolutionizing drug discovery and toxicology testing by reducing reliance on animal models. Professor Hartung explains how advancements in stem cell science, microfluidics, and artificial intelligence are converging to accelerate clinical trials, increase safety, and lower costs. The conversation also delves into the ethical considerations of biological computing, where organoids may one day aid in cognition and pattern recognition tasks.
