The puzzles of direct dark matter searches can find solution in the model of dark atoms, called O -helium, containing stable -2 charged lepton-like heavy particle O −− bound by ordinary Coulomb interaction with primordial helium 4 nuclei. Specific properties of this nuclear interacting dark matter can explain positive results of DAMA/NaI and DAMA/LIBRA experiments and negative results in cryogenic and heavy nuclei (like xenon) detectors. Astrophysical and collider probes for dark atom models as well as open questions of O -helium nuclear interaction with matter are discussed.
