The ICTP will celebrate the United Nations Day on 23 October with Trieste's other UN-affiliated scientific institutions, including the International Centre for Science and High Technology (ICS), the International Centre for Genetic Engineering and Biotechnology (ICGEB), and the Third World Academy of Sciences (TWAS). Local and regional officials will be invited to visit the Centre to learn more about the scientific research and training activities that take place at the ICTP and the other Trieste-based UN scientific facilities. Other celebrations will be taking place at UN organizations around the world.
