Once again, on Saturday October 5 PRBB will open its doors from 10 am to 7 pm. Scientists and PRBB staff will dedicate their day to explain what we do, and how and where we do it. We will play with science, talk about the projects we are working on, and show you our laboratories and the equipment we use. In summary, we propose you to spend a great day having fun with science and getting to know a large infrastructure of the city and those who work in it. And everything for free and for the whole family. Do not miss it! More info at http://www.prbb.org/openday
