This week on the Down East Journal, Naval Hospital Camp Lejeune is using futuristic simulation technology to train students and give experienced physicians a place to refine their skills. We speak with experts about the new simulation lab and explain how it works. And, a living history program this weekend in Beaufort focuses on the signs that served as markers for the Underground Railroad. The Down East Journal airs Friday at noon on all of the PRE stations, and Saturday at noon on News and Ideas.
