No Dark Matter Seen in Deepest Limits to Date

This experiment was attempting to directly detect specific individual dark matter particles over a range of masses and cross sections, and did not find any there.

There is still a wide variety of astrophysical evidence for some kind of dark matter [1]; this just pushes back the search to determine exactly what it is.
