Majorana bound states appear as edge zero-energy excitations of certain topological superconducting phases. Their non-locality and anyonic exchange statistics make them of interest for potential application to fault-tolerant topological quantum computation. Signatures compatible with Majorana end-states have been reported so far in local conductance measurements in nanostructures. New experimental platforms and theoretical efforts for proper characterization and manipulation of Majorana end-states are in progress and require several Majorana end-states, offering a rich scenario of new effects. I present here two of such effects: (i) the interaction-induced modification of the topological phases of time-reversal protected quasi 1-dimensional superconductors (BDI class), and (ii) a weak measurement scheme for the detection of intrinsic non-locality of Majorana end-states in a 6-Majorana based setup. In both cases I will discuss the measurable consequences of the effects in transport and charge-sensing-based measurements.
