A Philadelphia museum says its exhibit on the Silk Road will go on for a limited engagement after a dispute with the Chinese government. The University of Pennsylvania Museum of Archaeology and Anthropology said Friday, Feb. 11, 2011, that the exhibit will open with a full complement of mummies and more. Some of the artifacts are more than 3,800 years old. (AP Photo/Jae C. Hong, File)
