"The dark matter interpretation of the 3.5-keV line is inconsistent with blank-sky observations", Science  Vol. 367, Issue 6485, pp. 1465-1467 (2020), Claimed that there is no peak at 3.5 keV in the background spectra.

"Detection of Cross-Correlation between Gravitational Lensing and γ Rays", Phys. Rev. Lett. 124, 101102(2020), Observed a correlation between gamma rays and weak lensing mass distribution. It seems that blazers dominantly cause this correlation. Dark matter interpretation is not clear.

"No Evidence for Type Ia Supernova Luminosity Evolution: Evidence for Dark Energy is Robust", arXiv:2002.12382, Reply from Riess et. al. to the claim of Yonsei U.

"Search for the rare decay !" → $%&&̅ at J-PARC KOTO experiment", Presentation at KAON2019 conference by Satoshi Shinohara. 4 events are seen for K_L --> Pi0+nu,nubar channel. BSM ? Need to be checked more.

"Annual modulations from secular variations: relaxing DAMA?", arXiv:2002.00459, speculation that DAMA annual modulation may be due to the way analyzing the background data. Maybe not from DM signal. Interesting !

"Early-type Host Galaxies of Type Ia Supernovae. II. Evidence for Luminosity Evolution in Supernova Cosmology", arXiv:1912.04903, A team of Yonsei U. led by Young-Wook Lee claims that dark energy is not real ! But the data are questioned.

"Strongly baryon-dominated disk galaxies at the peak of galaxy formation ten billion years ago", R. Genzel et al., Nature 543, 397 (2019), Dark Matter in early Universe shows different rotation curve !

"New evidence supporting the existence of the hypothetic X17 particle", arXiv:1910.10459, A new ATOMKI experiment with he-4 supporting 17MeV dark photon !

"Light Dark Matter Search with Ionization Signals in XENON1T", PRL123, 251801 (2019), 22 ton day data. New limits to DM-nucleus scattering for 3–6 GeV , DM-electron scattering for > 30 MeV, and dark photons and axionlike particles for 0.186–1 keV.
