Sgt. Christopher Duke and wife Lauren Duke greet Rufus at PetAirways on Thursday, July 29, 2010, in Atlanta, Georgia. Rufus and two other dogs saved Duke's and other soldiers' lives while serving in Afghanistan when on the evening of Feb. 11, 2010, the dogs attacked a suicide bomber trying to enter their barracks, forcing the bomber to detonate his explosives in the entry corridor. Though five of the 50 soldiers present sustained injuries, none died that night thanks to the three dogs. One of the dogs was killed, the other two later recovered from their injuries. Sgt. Duke wrote to a veterans assistance group called "Hope for the Warriors" asking for the dogs to be brought to the United States, and $21,000 was raised in less than 3 months enabling the dogs to leave Afghanistan.

Female Afghan students attend Kabul university on July 6, 2010. The change in the status of women in Afghanistan has changed since the Taliban regime where women were forced to wear the burqa in public. The face of a woman was considered a source of corruption for men not related to them. They were not allowed to work and not allowed to be educated after the age of eight and then only permitted to study the Qur'an. Women wanting to be educated were forced to attend underground schools such as the Golden Needle Sewing School and along with their teachers risked execution if caught. They also were not allowed to be treated by male doctors unless accompanied by a male chaperone often leading to illnesses remaining untreated. (Majid Saeedi/Getty Images) #
