  Recent results for the $\eta_c$- and $J/\psi$-nucleus bound state energies
for various nuclei are presented. The attractive potentials for the $\eta_c$
and $J/\psi$ mesons in the nuclear medium originate, respectively, from the
in-medium enhanced $DD^{*}$ and $D\bar{D}$ loops in the $\eta_c$ and $J/\psi$
self energies. Our results suggest that the $\eta_c$ and $J/\psi$ mesons should
form bound states with all the nuclei considered.
