Query: Massive neutrinos and dark energy   We consider the impact of the Heidelberg-Moscow claim for a detection of
neutrino mass on the determination of the dark energy equation of state. By
combining the Heidelberg-Moscow result with the WMAP 3-years data and other
cosmological datasets we constrain the equation of state to -1.67< w <-1.05 at
95% c.l., While future data are certainly needed for a confirmation of the
controversial Heildelberg-Moscow claim, our result shows that future laboratory
searches for neutrino masses may play a crucial role in the determination of
the dark energy properties.
