Article: I was sure that I was to be killed. I became terribly nervous. I fumbled in my pockets to see if there were any cigarettes, which had escaped their search. I found one and because of my shaking hands, I could barely get it to my lips. But I had no matches, they had taken those. I looked through the bars at the guard. He did not make eye contact with me. I called out to him "Have you got a light?" He looked at me, shrugged and came over to light my cigarette. As he came close and lit the match, his eyes unconsciously locked with mine. At that moment, I smiled. I don't know why I did that. Perhaps it was nervousness, perhaps it was because, when you get very close, one to another, it is very hard not to smile. In any case, I smiled. In that instant, it was as though a spark jumped across the gap between our two hearts, our two human souls. I know he didn't want to, but my smile leaped through the bars and caused a smile on his lips, too. He lit my cigarette but stayed near, looking at me directly in the eyes and continuing to smile. I kept smiling at him, now thinking of him as a person and not just a guard. "Do you have kids?" he asked. "Yes, here, here." I took out my wallet and nervously fumbled for the pictures of my family. He, too, took out the pictures of his family and began to talk about his plans and hopes for them. My eyes were filled with tears. I said that I feared that I'd never see my family again, never have the chance to see them grow up. Tears came to his eyes, too. Suddenly, without another word, he unlocked my cell and silently led me out. Out of the prison, quietly and by back routes, out of the town. There, at the edge of town, he released me. And without another word, he turned back toward the town. Question: What is the most important factor in saving the man's life? Yes or no, is the answer "The smile."?

No

Article: Between 1996 and 2010, according to a study published in 2012, the use of computed tomography (CT) scans nearly increased by three times as much, from 52 scans per 1,000 patients to 149 scans per 1,000 patients. And those images certainly provided valuable information to help doctors diagnose hidden conditions that wouldn't have been possible without the added insight. But CT scans produce those detailed images using small amounts of radiation, and while the risk of that exposure is small, on a population level, increased reliance on the scans could drive a slight bump in cancer risk from CT. That's exactly what the latest study, published in the British Medical Journal, found. It's the largest study to date -- involving 10.9 million Australians born between 1985 and 2005. A team of researchers from Australia and Europe studied the cancer rates of Australian patients from birth to 19 years old who had CT scans in early childhood, and compared them to those who did not receive the scans. Most of the cases were followed for 10 to 17 years, and by the end of the study period, 3,150 of the 680,000 patients exposed to CT scans during childhood and young adulthood developed cancer and 57,542 of the remaining participants, who were not exposed, developed cancer. Those who were scanned had a 24% greater risk of cancer than those who did not receive them, with the risk increasing by 16% for each additional CT. The risk was highest for children who received scans before age five; they showed a 35% increased chance of developing a cancer during the study period than those who weren't scanned at this age. That research is still ongoing, however, and in the meantime, doctors and patients are left to find the delicate balance between how necessary scans are to diagnose disease, and their potential risk of causing cancer, which, most experts say, is still very small. "All parties, including patients and families, need to work together to make sure that CT scans are limited to situations where there is a definite ... Question: Which might be a suggestion from the researchers of the study? Yes or no, is the answer "Patients should take a cautious attitude to CT scans."?

No

Article: Every small child knows the panic of losing sight of its mother in the supermarket, and as these delightful pictures show, small whales obviously feel the same way. Taken by a British diver who was following the sperm whale calf, _ show the minute the baby - who had lost track of its mum - found her again in the sea off the Azores. Soaring 30ft across the waves, the newborn slammed its body onto the water with joy after becoming separated from its family group in the chilly waters. But the whale calf was doing more than just jumping for joy. British biologist and dive guide Justin Hart, 44, who took the pictures, says that young whales communicate with older ones in the ocean by creating a slamming sound which travels through the water to the ears of the adults deep below. By leaping out of the water and slamming its 12ft long body onto the surface of the sea up to 30 times, the baby whale is telling its relatives where it is so they can regroup. He said: "We had been following the sperm whale calf for most of the day. Sperm whales, of all the whales and dolphins, are the species that dive the deepest and for the longest time." "The calves have to follow what's going on below them from the surface as best they can probably listening to the echo location clicks of the adults." "However, sometimes the adults re-surface far out of sight of the calf, and in this situation the whales often leap out of the water causing a large bang as their bodies hit the surface. In this way, the whale family could regroup." He added: "When I took the photo, two adults' females had just resurfaced and the calf quite literally began jumping for joy." Mr. Hart captured the rare image four miles from the port of Lajes do Pico while he was working as a crewman on an underwater documentary with special license to film sperm whales in the area. Sperm whales live in nearly all the world's oceans in groups of about 15 to 20 animals and they practice communal childcare. The calves do not have to follow their mother too closely as sperm...
