Storage of freshly produced secondary particles in a storage ring is a straightforward way to achieve the most efficient use of rarest species. Employing storage rings for precision physics experiments with highly-charged ions (HCI) at the intersection of atomic, nuclear, plasma and astrophysics is a rapidly developing field of research. The number of physics cases is enormous. The focus in this presentation will be on the most recent results obtained at the Experimental Storage Ring ESR of GSI in Darmstadt.

The ESR is presently the only instrument dedicatedly utilized for precision studies of decays of HCIs. Radioactive decays of HCIs can be very different as known in neutral atoms. Some decay channels can be blocked while new ones can become open. Such decays reflect atom-nucleus interactions and are relevant for atomic physics and nuclear structure as well as for nucleosynthesis in stellar objects.

The experiments performed at the heavy-ion storage rings in operation will be put in the context of the present research programs in a worldwide context, where, thanks to fascinating results achieved in the last decade, a number of projects is planned.
