A new and compelling theory of Dark Matter (DM) is explained at https://aeon.co/essays/is-dark-matter-subatomic-particles-a-superfluid-or-both?utm_source=Aeon+Newsletter&utm_campaign=fddf0e590c-Daily_Monday_February_1_20162_1_2016&utm_medium=email&utm_term=0_411a82e59d-fddf0e590c-68855917

Finally, the superfluid model explains why physicists have not been able to find dark matter particles. Starting in the 1980s, dozens of different experiments have looked for direct evidence of such particles. The experiments generally use large, well-shielded tanks of different materials that might, on rare occasions, interact with a dark matter particle and produce an observable signal. Despite a wide variety of techniques and materials, using detectors that are carefully shielded and hidden away in underground mines to filter out false signals, no conclusive evidence of dark matter has been found.
