KamLAND is a 1000-ton liquid scintillator detector designed
for sudying the solar neutrino puzzle using anti-neutrinos from
nuclear reactors. Based on 162 ton-yr of data, a deficit in the
anti-neutrino flux is observed. Assuming CPT invariance, the first 
results from KamLAND have ruled out all solutions to the solar neutrino
problem except for the 'large mixing angle' region.
