Evidence of Dark Matter?

Researchers identified signals which could have been caused dark matter particles known as “wimps”, or weakly interacting massive particles, colliding with normal matter.
Although the results are uncertain, further experiments could establish whether dark matter, which makes up a quarter of our universe and holds galaxies together, has indeed been glimpsed for the first time. 
Attempts to pin down dark matter have proven tricky because although it is all around us, it does not directly interact with visible matter except in rare circumstances. 
But deep underground at the Cryogenic Dark Matter Search in Minnesota, researchers have been attempting to detect instances of dark matter particles clashing with the nuclei of atoms.
Full story here.
