The first reported positron/electron ratio results from the Alpha Magnetic Spectrometer (AMS-02) experiment (see earlier post) on the ISS show consistency with production from dark matter interactions but more data will be needed to insure this is not due to other sources: Shining light on elusive dark matter / DAMA mission –  ESA

Scientists are confident that AMS-02 will deliver the data needed to solve the riddle of where the changes in positron ratio come from in the near future.

“Over the coming months, AMS will be able to tell us conclusively whether these positrons are a signal for dark matter, or whether they have some other origin.” says Professor Samuel Ting, the project’s lead investigator.
