The entrance to the Sanford lab is through the Ross Shaft building of the old Homestake Mine in Lead, S.D.
In Lead, S.D., a steel cage drops almost a mile below ground into the Sanford Underground Laboratory. It's formerly the deepest underground gold mine in North America, and when it closed a decade ago, state officials hoped that an underground science laboratory along with on-site university classes could spur economic development.

In 2003, in the run-up to the invasion of Iraq, President George W. Bush argued that an occupation could work because history provided an example in a non-Christian, non-white, non-Western country: the United States' occupation of Japan during World War II.
He cited the work of historian John Dower, the pre-eminent scholar of postwar Japan, who promptly published an op-ed to protest a misuse of history. His work, he said, should have led President Bush to the opposite conclusion.

VICE PRESIDENT DICK CHENEY: A mistake.

Not using one's best efforts to win a match. Few Americans know much about the sport of badminton, but that rule will likely be the subject of a lot of discussion over the next few days. Today, badminton officials at the London Olympics disqualified eight players for tanking. Women's doubles teams from South Korea, Indonesia and China drew boos yesterday when it looked like they deliberately lost preliminary matches to engineer more congenial match-ups later in the tournament.
Plenty To Smile About: Weightlifter Maiya Maneza of Kazakhstan celebrates on the podium with her new 400-gram gold medal, matching the feat of her compatriot Zulfiya Chinshanlo. The Kazakh Olympians will each receive a $250,000 bonus.
Weighing 400 grams, the Olympic gold medals that are being doled out at the London 2012 Summer Games are the heaviest ever, according to reports. But that doesn't mean they're the most valuable: at an estimated $620.82, they're nearly $590 short of the $1,207.86 value held by a gold medal from the Stockholm Games of 1912.
The discrepancy stems from the fact that the 2012 gold medals contain only 6 grams of gold; the rest is silver and copper. In fact, the London bling contains more copper than gold, which is only used to coat the medals with a plating layer.
Scientists reported new evidence Wednesday that supports a provocative theory about cancer.
Three separate teams of scientists said they had, for the first time, shown that so-called cancer stem cells can be found naturally in brain tumors and early forms of skin and colon cancer.
Evidence has been mounting in recent years for the existence of these cells, which would be especially insidious. They are believed to resist standard chemotherapy and radiation and fuel the growth of tumors and relapses.
