Q: Article: After an extra day in space,the crew of Discovery returned to Earth,landing at Edwards Air Force Base in California early on Tuesday morning.The shuttle and its crew spent two weeks in space,most of it aboard the International Space Station.It was the first flight of NASA's spaceshuttle fleet since February 2003,when the shuttle Columbia came apart while reentering Earth's atmosphere. NASA officials delayed Discovery's return for one day because of cloudy weather in Florida,where the shuttle was supposed to lanD. On Tuesday morning,mission controllers directed Discovery to a landing site in California,where the skies were clear.The crew members will have to wait until Wednesday to see their families when they all meet together in Houston at the Johnson Space Center. Discovery had a very busy mission in space,compared to past missions.The space shuttle docked with the International Space Station most of the journey,delivering badly needed supplies and repairing damaged parts.The crew spent a lot of time testing new repair techniques on their own shuttle,conducting three different spacewalks(where astronauts exit the space shuttle to do work outside).On the third spacewalk,astronaut Steve Robinson went underneath the shuttle to remove material sticking out from between the spacecraft's protective tiles. There were concerns in the last remaining days of Discovery's mission that a torn heat blanket--another shield against overheating in the space shuttle--may pose a problem to crew members. NASA officials and technicians worked on ways that the crew could fix the problem, but later decided it was not a risk. With the shuttle and its crew safely back on firm ground, NASA is hailing this mission, labeled STS114,as a huge success. "I hope this shows people that we're coming back," NASA spaceflight chief Bill Readdy said after Discovery's successful landing. "We've got some more work to do. We know what we need to do and we'll do it.

Q: Article: After three military tours in Iraq and three in Afghanistan, Dennis Swols gets angry easily. He is unable to really talk about his time on the battlefield. But as Swols sits in a clinic at Fort Bragg, his hand drops to the furry head beside him. His mood brightens. Sitting at his feet, Lexy , a 5-year-old German shepherd, gives Swols a few moments of distraction . It's her job. And, according to Swols, she is good at it. "I have a hard time talking to people about my battlefield experiences and everything," says Swols, who took part in several wars. Now he's been suffering from post-traumatic stress disorder . "I just pet Lexy. Or I'm sitting here and we won't talk about military things. We'll just talk about the dog. My day is better every time I come in." For Doctor Christine Rumayor, Lexy is a partner and a living, breathing medical tool. The dog can calm a patient and make a therapy appointment a little more enjoyable. Animal therapy is used in only a few other army medical centers. A small number of dogs like Lexy are being used almost as co-therapists. The army is struggling to address stress disorders and mental health problems brought by more than ten years of war. One of the big difficulties is getting soldiers to seek treatment. Lexy, it turns out, is particularly good at that. Rumayor , who uses Lexy in her practice, said there was a resistance at first. "You don't expect everyone to think they can just bring their dog to work," she said. Walking around the base, she uses Lexy to attract soldiers, and then draws them into conversation. "There's nothing better than coming to an appointment where you get to have a warm furry thing that you get to pet all the time. People don't want to come in the door. When they see Lexy coming in, it makes them want to come in the door."
Answer: He is suffering from post-war stress.

Q: Article: Ashlyn Blocker could break her arm and not know it. That's because Ashlyn, 13, can't feel pain. That might sound like a cool superpower. But without pain, everyday activities can be hazardous for Ashlyn. In fact, they could kill her. When Ashlyn was born, no one knew that she couldn't feel pain. But soon there was hints that something was wrong. When Ashlyn's teeth grew in, she almost chewed off part on her tongue. Ashlyn's parents took her to doctor for tests. The doctors discovered that Ashlyn couldn't feel pain, a condition called congenital insensitivity to pain(CIPA). Fewer than 100 people in the United States have it. There is no cure. . "Sometimes it's frustrating," she admits. But Ashlyn doesn't let anything stop her from doing things she wants to do. "I just have to be careful," she says. For years, Ashlyn didn't know anyone else who had CIPA. That made it harder to deal with her condition. "I felt alone," she says. One night she dreamed that there was a camp for kids like her. In 2011, Ashly's mom made the dream come true. She started Camp Painless But Hopeless. The camp is for children who have CIPA. Every November, they and their families spend four days together. The campers get to do daring activities like rock climbing--wearing safety equipment. Someday, Ashlyn wants to be a director at the camp so she can help others who can't feel pain. In fact, Ashlyn is already helping others. Since 2004, she has let scientists study her to learn more about her condition. What they are finding out could one day help people who suffer from the same disease. That makes her feel great. "I believe there is a reason for everything, " she says, "There is a reason for me."
