Animals concentrate all the intensity of a life in a magical, endless day: they are here to feed, fight and raise their young, taking advantage of this period of abundance. Why do teenagers always seem to be looking for trouble? Neuroscience explores the most turbulent age of life and discovers why kids love risk. Barbara Bernardini and Marco Visalberghi went to the University of Texas, Austin, to tell the story. Alberto Angela is in Moscow, where the Bolshoi Theatre, one of the symbols of the cultural life of an entire nation, has undergone a long restoration project to ensure its stability. Highly specialized work groups have followed the work, which has given the Theatre back its ancient splendor and its famous excellent acoustics.
