If correct it would constitute a ``smoking gun'' for dark matter annihilations. Interestingly, the spectra of the cosmic ray electrons detected by PAMELA and Fermi-LAT both show tiny wiggle-like structure at $\\sim 100$ GeV, which might indicate a weak signal of the annihilation of $\\sim 130$ GeV dark matter particles into electrons/positrons with a velocity-weighted cross section $\\langle\\sigma v\\rangle_{\\rm \\chi\\chi\\rightarrow e^{+}e^{-}} \\sim 4\\times10^{-26}~{\\rm cm^{3}~s^{-1}}$.
