Search for dark matter comes up empty so far

LEAD, S.D. (AP) — Nearly a mile underground in an abandoned gold mine, one of the most important quests in physics has come up empty-handed in the search for the elusive substance known as dark matter, scientists announced today. The most advanced Earth-based search for the mysterious material that has mass but cannot be seen turned up “absolutely no signal” of dark matter, said Richard Gaitskell of Brown University, a scientist working on the Large Underground Xenon experiment. A detector attached to the International Space Station has so far also failed to find any dark matter.
