Zichichi, em. prof. of Adv. Phys., U. of Bologna, has authored over 1100 sci. papers incl. 7 discoveries, 5 inventions, 3 original ideas which opened new avenues in high energy subnuclear physics and 4 high-precision measurements of fundamental physics properties. Among the discoveries: nuclear antimatter; among the inventions: an electronic circuit for time-of-flight measurements with a precision of seventy thousandth of a billionth of a second; among the original ideas that which brought to the discovery of the third column in the fundamental structure of the Universe. The great projects of European Physics (LEP and LAA at CERN, GRAN SASSO at INFN, HERA at DESY) are linked to his name, for his seminal contributions in their conception, study and implementation phases. He has been in charge of high-level offices and received 102 prizes, distinctions and medals in 15 countries.

Baralle (PhD 1969, U. of Buenos Aires -UBA) has been director general at Intl. Centre for Genetic Eng. and Biotech. (ICGEB) in Trieste, Italy (2004-14). He now leads the ICGEB RNA Biology Group and is vis. prof. in Buenos Aires. From 1968 to 1974 studied Medicine at UBA and completed his MD in 1984 at the U. of Naples. Previously, he worked at the Instituto de Investigaciones Bioquímicas Fundación Campomar and at the MRC Lab. of Molecular Biology, Cambridge, UK. From 1980 to 1990, he was university lecturer of pathology at Oxford and fellow of Magdalen College. In 1990 he joined ICGEB. He is an elected member of EMBO and of the Argentine Acad. of Sciences. In 1977 he published the first complete primary structure of an eukaryotic mRNA, βglobin mRNA. His current research focuses on RNA splicing and RNA-protein interactions in neurodegenerative diseases. He has published over 220 papers.
