“This thing was my answer to lack of a window in my lab,” Matt Wawersik says, gesturing to the large monitor on the wall. “This is a great teaching tool.” Wawersik studies the genetics of stem cells in fruit flies, inducing mutation to identify the cause of change in individual stem cells. His work has implications for human health issues ranging from fertility to cancer: “There’s a cancer stem cell hypothesis that basically says that the hardest to treat cancers actually have cancer stem cells at the root of them—stem cells that have transformed into a cancer cell.”
