CAMBRIDGE, MA–While attempting to isolate a gene believed to be key to the development of the autoimmune disorder myasthenia gravis Monday, MIT geneticists Dr. Stephen Eng and Dr. Caryn Sohn made a breakthrough discovery: each other. "I was examining some cellular tissue when my electron microscope broke," Eng said. "Caryn offered to share her microscope, and each of us looked at the tissue through one of the eyepieces. At one point, our cheeks lightly touched, and I looked over and realized how beautiful she looks without her glasses." Sohn felt a similar rush of emotion, saying, "I always saw Stephen as a respected colleague and a dedicated scientist. But that afternoon, for the first time, I saw him as a man." A process of trial-and-error sexual experimentation commenced later that evening, continuing well into the night.
