Several institutes of the CAS presented results of their most recent discoveries. The Institute of Organic Chemistry and Biochemistry, among others, displayed its research aimed at seeking new human medications for lifestyle diseases and showed, for instance, a human cell as a miniature “chemical plant” in which thousands of actions bring about the healthy functioning of an organism. The institute also prepared an exhibition entitled Czech Science fighting viruses, which also introduced one of the protagonists in this field, outstanding Czech scientist Antonín Holý.One of the Czech lecturers who addressed the audience both at the EXPO and in Ispra was Lenka Maletínská.
