Weizmann Institute experts in tumor and molecular genetics - Profs. Yoram Groner, David Yaffe and Doron Lancet and Dr. Orly Reiner - recently visited the Moroccan town of Essaouira (Mogador), where they participated in a conference on genetic diseases that marked the dedication of the Ibn Maimon International Institute of Science. (Ibn Maimon is the Arabic name of Maimonides, the Jewish philosopher and physician who wrote several medical books, including an important work on hygiene.) Also taking part in the meeting were scientists and public figures from Cyprus, France, Morocco, Tunisia and the United States.Heading in the opposite direction were two Moroccan physicists, Prof. El Hassane Saidi of the Mohammed V University in Rabat and Prof. Mohammed Saber of the Moulay Ismail University in Meknes. Among the first Moroccan scientists to visit Israel, they came to the Institute at the invitation of Weizmann physicists whom they met at a scientific meeting in Dahab, Egypt. "I wish more people in the Arab world knew what Israel is really like," commented Saber. "I'm sure that would benefit relations between our countries."
