Extended Text: BERKELEY, CA – First they were seen to go away, now, for the first time, they’ve been seen coming back. An international team of researchers at KamLAND, an underground neutrino detector in central Japan, has shown that not only do anti-neutrinos emanating from nearby nuclear reactors "disappear," they also "reappear." This is further evidence that the three known types or "flavors" of neutrinos — electron, muon and tau — all have mass and can oscillate or change from one type to another.
