The World's Most Sensitive Dark Matter Detector Is Now Up and Running

The XENON1T detector hasn't found any dark matter particles yet, but it has carried out a 30-day science run, and project scientists are optimistic about the future. "The best result on dark matter so far! … and we have just started!" the XENON1T team said in a statement. The XENON1T experiment is located deep beneath a mountain at the Gran Sasso National Laboratory in Italy (known by its Italian acronym, LNGS) so it can be shielded from interference caused by cosmic rays and other radiation sources on Earth's surface.
