Quest For Dark Matter Goes Underground

From CNN.com - Technology:

LOS ANGELES, California (AP) -- In deep underground laboratories around the globe, a high-tech race is on to spot dark matter, the invisible cosmic glue that's believed to keep galaxies from spinning apart. Whoever discovers the nature of dark matter would solve one of modern science's greatest mysteries and be a shoo-in for the Nobel Prize. Yet it's more than just a brainy exercise. Deciphering dark matter -- along with a better understanding of another mysterious force called dark energy -- could help reveal the fate of the universe. Previous hunts for the hypothetical matter have turned up nothing, but that has not deterred some two dozen research teams from plumbing the darkness of idled mines and tunnel shafts for a fleeting glimpse. Dark-matter detecting machines today are more powerful than previous generations, but even the best has failed so far to catch a whiff of the stuff. Many teams are now building bigger detectors or toying with novel technologies to aid in the hunt. "We're in the golden age of dark matter search," said Sean Carroll, a California Institute of Technology theoretical physicist who has no role in the experiments. "It's looking good for some breakthroughs to happen."
