We review a testable, the axion quark nugget (AQN) model outside of thestandard WIMP paradigm. The model was originally invented to explain theobserved similarity between the dark and the visible components, $\Omega_{\rmDM}\approx \Omega_{\rm visible}$ in a natural way as both types of matter areformed during the same QCD transition and proportional to the same dimensionalfundamental parameter of the system, $\Lambda_{\rm QCD}$. In this framework thebaryogenesis is actually a charge segregation (rather than charge generation)process which is operational due to the $\cal{CP}$-odd axion field,while theglobal baryon number of the Universe remains zero. The nuggets and anti-nuggetsare strongly interacting but macroscopically large objects with approximatelynuclear density. We overview several specific recent applications of thisframework. First, we discuss the "solar corona mystery" when the so-callednanoflares are identified with the AQN annihilation events in corona. Secondly,we review a proposal that the recently observed by the Telescope Array puzzlingevents is a result of the annihilation events of the AQNs under thunderstorm.Finally, we overview a broadband strategy which could lead to the discovery theAQN-induced axions representing the heart of the construction.
