Number 473 (Story #4), March 3, 2000 by Phillip F. Schewe and Ben Stein DARK MATTER UPDATE. At the dark matter detection meeting in Marina del Rey, California last week (Update 473) a group form Gran Sasso, Italy reported detecting evidence for dark matter particles. The Cryogenic Dark Matter Search collaboration (10 US institutions), using a different detection scheme, reported finding no evidence for such particles, and asserted that their results were incompatible with the Gran Sasso finding.
