Just a few years after the discovery of the Higgs boson completed the collection of particles and fields composing the Standard Model, low-background searches for dark matter and neutrinoless double beta decay hold the key for unlocking new physical laws extending Beyond the Standard Model. Multiple pieces of strong evidence point to the existence of dark matter (and dark energy), providing the most convincing argument to date for the presence of new physical laws. Ninety years after the hypothesis of Majorana, neutrinos are the sole Standard Model particles whose fundamental quantum representation has not yet been established: were they found to be Majorana fermions, a dark sector of neutrinos could emerge, mirroring its known counterpart, and would likely play a significant role in solving the dark matter puzzle. I will review the status and prospects of searches for very rare phenomena, focusing on the very challenging requirements for the next transformational discovery to be delivered via underground experiments.
