sign of dark matter
''Dark matter is proving less shadowy than its name suggests. Its signature may have been detected by a balloon-borne experiment that measured a surprisingly high number of energetic electrons streaming in from space. ...
the signal peaked at 650 GeV and then rapidly declined to the background level at 800 GeV. According to Wefel, this is the kind of signature you would expect if a type of exotic particle known as a Kaluza Klein particle was the dark matter culprit, with the peak at 650 GeV corresponding to its mass.''
