The role played by subthreshold meson-baryon dynamics is demonstrated in K--atom, (K) over bar -nuclear and eta-nuclear bound-state calculations within in-medium models of (K) over barN and eta N interactions. New analyses of kaonic atom data reveal appreciable multi-nucleon contributions. Calculations of eta-nuclear bound states show, in particular, that the eta N scattering length is not a useful indicator of whether or not eta mesons bind in nuclei nor of the widths anticipated for such states.
