A journey in Borneo inaugurates the new series of documentaries made by Nicolas Hulot: one of the last Edens of the earth described with spectacular and unforgettable images in the first episode of Superquark, broadcast Thursday at 9:00 pm on RaiUno. A guided tour, with Alberto Angela, in the heart of Tokyo where, before dawn, the large Tsukiji fish market comes to life, unique in the world for its size and quantity of fish: the tuna auction, the ice factory, the strangest fish species, curiosities and humanity in a sanctuary where business and tradition coexist. For the new column "75 years ago" curated by Fiorella Ravera and Giancarlo Di Giovine, the historic rooms of the 1930s of the Forlanini Hospital in Rome, specially transformed into a set for Superquark, to tell how people were treated in the past and what progress has been made to date. New technologies at the service of an investigation, human instinct and science to solve the most complex cases.
