Dark matter seems to be receding further into the shadows. Last year, researchers thought they may have spotted its signature when a balloon-borne experiment called ATIC detected a bizarre spike in the number of high-energy electrons streaming in from space.
But now, NASA's Fermi space telescope finds no such spike – only subtle hints of a slight increase, suggesting that dark matter is not leaving any obvious trace in the charged particles detected from space.
