The highlights of the 2011 Chalonge Colloquium will be summarized. This Colloquium was within the astrofundamental physics spirit of the Chalonge School, focalized on recent observational and theoretical progress in the framework of the Standard Model of the Universe: 1) CMB anisotropies, 2) Dark matter: small scales, galaxy formation (observations, theory and numerical simulations), heliosismology. 3) Neutrinos: masses and mixing, sterile neutrinos at the eV and at the keV mass scale. 4) Astrophysical black-holes. Filaments and structure of the ISM. 5) The JWST telescope. In summary, Warm Dark Matter emerged impressively over Cold Dark Matter whose small -galactic- scale problems are staggering. LambdaWDM solves naturally the problems of LambdaCDM and agrees with the observations at small as well as large and cosmological scales. The DM particle mass should be in the keV scale. KeV sterile neutrinos appear as front running candidates.
