Abstract
This presentation discusses some recent developments in our under-standing of the lightest quark-antiquark excitations, both of the condensed QCD vacuum and in a nuclear medium. We focus on two selected topics: the thermodynamics of the chiral condensate and in-medium s-wave interactions of pions with special emphasis on the recently observed deeply bound pionic atom states.
