In the heart of Rome, a stone's throw from the Quirinale, stands one of the capital's most beautiful and art-rich buildings: Palazzo Barberini, home to part of the National Galleries of Ancient Art. Alberto Angela guides us through this treasure trove of Baroque architecture, a precious repository of absolute masterpieces of Italian painting. Barbara Gallavotti and Francesca Marcelli, meanwhile, travel to Switzerland to follow a group of researchers studying the factors that favor the transmission of influenza. Giovanni Carrada and Emanuela Gardenghi reveal the secrets of the extraordinary technological miracle of Israel, one of the smallest but most innovative countries in the world. After the report, Piero Angela will delve deeper into the topic with a studio experiment by Paco Lanciano.
