I review a novel and non-perturbative way of breaking Supersymmetry in the
flavour sector of electrically neutral particles, as a result of flavour mixing
in the presence of stringy quantum gravity space-time foam backgrounds that
violate Lorentz and CPT symmetries. In these models, part of the mixing may
itself be induced dynamically by the interactions of the flavoured particles
with the space-time foam.Comment: Invited talk at Corfu 2010 School and Workshops, September 2010,
