Physicists Find Dark Matter?

In a recent Wired article I read about a new experiment may have found the first direct evidence of dark matter particles. Theorists believe that dark matter, made up of of weakly-interacting massive particles, composes 23 percent of the universe, but no one has ever directly detected one of these WIMPs. Now, physicists have announced they've spotted electrons with just about the amount of energy they would have expected to be made by a particular kind of WIMP. John Wefel of Louisiana State University and colleagues report in Nature Wednesday that they could have detected "Kaluza-Klein" electron-positron pairs resulting from the annihilation of these WIMPS.
