Maybe, but I would wait to hear from a physicist. When I was a student, one of the most important papers one year was about a dark matter (WIMP) detector that failed to find anything, thus "trimming the parameter space" for what the particles might look like. If this is a genuine clue, it's probably very exciting.

> Nearly 85 percent of the universe is made of dark matter

It's a bit ambiguous too: 85% is the proportion of the total mass made up of dark matter. Normally we'd say that 26% of the universe is dark matter, 5% is baryonic matter and the rest is dark energy.
