The world is entering a new era of conflict: more violent, more fragmented, and with more civilians caught in the crossfire than at any time since World War II. But the consequences of war may extend far beyond the battlefield. Rana Dajani, Jordanian molecular biologist and long-time member of the Tällberg network, is part of a research team uncovering how traumatic violence might alter gene expression and affect not only survivors but also their children and grandchildren. In this episode, she explains the emerging science behind intergenerational trauma and explores what these findings could mean for societies living through—and after—conflict.
