In 1972, Dr. Kapikian identified the Norwalk virus, the first virus associated with acute epidemic gastroenteritis, gaining recognition as "the father of human gastroenteritis vir...Scientists observe infectious prion proteins invade and move within brain cells
... photo images with a confocal microscope. Confocal microscopy uses laser light to scan many thin sections of a fluorescent sample, resulting in a clean three-dimensional image. The painstaking job of analyzing and deciphering about 1,000 different images primarily belonged to Dr. Magalhes--who filled a file cab...Leading genomic technology expert to present Dickson Prize Lecture at Pitt
