New results from polarized p-p collisions at {radical}(s) = 200 GeV of double longitudinal spin asymmetry in {pi}0 production using the PHENIX detector in the 2005 RHIC run are presented. Both positive and negative maximal gluon polarization scenarios are inconsistent with the data. The data is consistent with small {delta}g, including {delta}g = 0.
