4th round of this year’s competition titled "30 years of Slovakia" deals with the development of the field of Slovak science in the past 30 years. From Chinese literature, Mayan civilisations to unique discoveries in natural sciences, we look at both the problems as well as the achievements Slovak scientists encounter. Few days ago, Nobel Prize laureate Emmanuelle Charpentier visited Slovakia to talk about what future holds for scientists as well as the general public.
