Radiative see-saw; fermion masses; grand unification.

In $SO(10)$, the type-I and type-II see-saw scales $\geqq 10^{12}$ GeV are far away from being probed by direct experimental tests. In the absence of supersymmetry, we show how experimentally verifiable radiative see-saw formula of Ma type is realized in non-SUSY $SO(10)$ while fulfilling the twin objectives: precision gauge coupling unification and dark matter. This model is expected to have a dramatic impact on neutrino physics, dark matter and all fermion masses and mixings.
