Our bodies contain nine bacteria for every human cell. And we don't have a good relationship with all of them. With Barbara Gallavotti and Daniela Franco, we'll travel to Belgium to understand how to treat the bacteria responsible for a truly unbearable odor and how they can be transplanted. Between physics and technology: Paolo Magliocco and Andrea Pasquini will demonstrate how systems work that can make mountain climbing safe, even for the less experienced. What kind of job will a child who goes to school today have tomorrow? Paolo Magliocco and Federica Calvia traveled to the University of Oxford, where a study is trying to identify the most sought-after professions of the future.
