The RESCUE project officially ends today. The last five years have been quite remarkable: so many hours in the lab or at the blackboard, discussing ideas, papers or the next conference presentation. So many beers, pizzas and more recently videoconferences while working from home. So many students coming into the lab and getting out with a new laurea or a PhD. This project changed the lives of many people. The journey will continue on this website, in the lab and in our memories.
