Cosmic Antimatter Excess Confirmed

sciencehabit writes "In 2008, the Italian satellite PAMELA picked up an unusual signal: a spike in antimatter particles whizzing through space. The discovery, controversial at the time, hinted that physicists might be coming close to detecting dark matter, an enigmatic substance thought to account for 85% of the matter in the universe. Now, new data from NASA's Fermi Gamma-ray Space Telescope confirm the spike (abstract)."

    While I do notice the trend upward as energy increases its not that clear. You know, its easy to shape statistics results when you know what it should look like.
    Damn lies!
