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.
U.S. Olympic boxing team captain Jamel Herring lost his light welterweight bout yesterday, but it's not the first setback he's faced — and he says he won't let his team lose its momentum in the London Olympics because of his defeat.
American swimmer Nathan Adrian's name hasn't been on everyone's mind, the way that Michael Phelps' or Ryan Lochte's has. But he did something that even Lochte couldn't do this week: beat Yannick Agnel in a head-to-head race.
Adrian's time of 47.52 seconds in the men's 100-meter freestyle gave him his first individual gold medal, as he also beat James Magnussen of Australia, who came in second, and Brent Hayden of Canada.
Decorated fencer Mariel Zagunis, who carried the U.S. flag into Olympic Stadium as part of the London 2012 opening ceremony, lost in the bronze medal match in the sabre Wednesday afternoon, falling to Olga Kharlan of Ukraine, 15-10.
The loss means that Zagunis, 27, will leave London without a medal — there is no team sabre medal at this year's Olympics (we'll post more about that situation soon).

U.S. gymnast Danell Leyva has won the bronze medal in the men's all-around competition in London. The gold was taken by Japanese star Kohei Uchimura, while the silver medal went to Marcel Nguyen of Germany.
With a final score of 92.690, Uchimura was nearly 2 points ahead of Leyva, at 90.698. And with his win, Uchimura vanquished the disappointments of his 2008 Beijing, when his struggles on the pommel horse cost him a gold medal.
