A mass relation for neutrinos
  A generalization of the well-known Georgi-Jarlskog relation m_{\mu}/m_{\tau} = 3 (m_s/m_b) to neutrinos is found in the context of SO(10). This new relation is m_{\nu_\mu}/m_{\nu_\tau} = 16 (m_c/m_t), which is consistent with present data, assuming the small-angle MSW solution to the solar neutrino problem.
