In the last ten years, impressive scientific results were obtained at radioactive nuclear beams (RNB) facilities around the world. The existing RNB facilities are in a process of continuous upgrades and improvement. In parallel, the facilities of a future generation are actively discussed and numerous R&D studies are performed.  I will discuss some new developments such as 1) application of implanted helium targets for RNB experiments, 2) in-source spectroscopy with a laser ionizing source, 3) in-trap conversion electron spectroscopy, and 4) conversion of relativistic products of fragmentation to high-quality low-energy beam. These experiments and R&D programs were performed at several RNB facilities in Europe and the US (Louvain-la-Neuve , ISOLDE, and NSCL).  In this discussion, I will try to give a flavor of a broad range of activities and a rich variety of physical phenomena that one encounters working at RNB laboratories.
