Experimental evidence for medium modifications of hadron properties is discussed. A first generation of experiments has reported interesting effects, and second-generation experiments such as HADES at GSI Darmstadt are in progress. In the future, these studies will be extended into the charm sector using PANDA, a state-of-the-art universal detector for strong interaction studies at the high-energy antiproton storage ring HESR at the future FAIR facility.
