We report on recent progress in theoretical studies of mesic atoms and nuclei performed by the Jerusalem–Prague Collaboration. We present calculations of η few-nucleon systems within the stochastic variational method. Further, we discuss K− multinucleon interactions in the nuclear medium and demonstrate their role in kaonic atoms and nuclei. Finally, we introduce a microscopic model for K−NN absorption in nuclear matter, developed very recently by J. Hrtánková and À. Ramos.
