Article: Offering a powerful new tool against terrorism, researchers have found a way to detect lies in the liar's blushing face. The technique, described in the journal Nature, uses a thermal camera to detect the sudden shift of blood flow in the face. The system performed as a traditional polygraph , the scientists report. Pushed by technological advances and with fresh interest since Sept.11, the discovery is part of the development in the scientific study of detection. Although the lie remains a mysterious phenomenon, researchers in recent years have found a number of new methods that might take the place of the polygraph, from brain scans, to slight changes in eye movement, to sparks of electrical activity that signal a person has seen a victim or a crime scene before. The new finding says, when a person tells a lie, there is a sudden change of blood to the area around the eyes. Although the change is not ordinary visible, the blood warms the skin, causing bands of color1 to appear through a camera sensitive to heat. One advantage of the camera can provide answers quickly, and doesn't require a highly trained expert to operate it or explain its results. In theory, this new technology could be used anywhere large numbers of people need to be quickly screened. But some scientists say the technology would need to be improved before it is ready for use, for it is possible that there are other reactions that cause a sudden change in blood flow in the face and there is also the danger that people will learn to fool the machine, the same way they try to fool polygraph examiners by controlling their breathing or taking drugs to relax themselves.

Article: A desert is a beautiful land of silence and space. The sun shines, the wind blows, and time and space seem endless. Nothing is soft. The sand and rocks are hard, and many of the plants even have hard needles instead of leaves. The size and location of the world's deserts are always changing. Over millions of years, as climates change and mountains rise, new dry and wet areas develop. But within the last 100 yeas, deserts have been growing at a frightening speed. This is partly because of natural changes, but the greatest makers are humans. Humans can make deserts, but humans can also prevent their growth. Algeria Mauritania is planting a similar wall around Nouakchott, the capital. Iran puts a thin covering of petroleum on sandy areas and plants trees. The oil keeps the water and small trees in the land, and men on motorcycles keep the sheep and goats away. The USSR and India are building long canals to bring water to desert areas.

Article: I have forgotten the name of an old lady who was a customer on my paper route when I was a twelve-year-old boy back in 1954. Yet it seems like just yesterday that she taught me a lesson in forgiveness that I can only hope to pass on to someone else someday. On a Saturday afternoon, a friend and I were throwing rocks onto the roof of the old lady's house. I found a smooth rock and sent it. The stone headed straight for a small window on the old lady's back door. At the sound of broken glass, we took off from the old lady's yard. I was too scared about getting caught that first night. However, a few days later when I was sure that I hadn't been discovered, I started to feel guilty for her misfortune. I decided to save my paper delivery money, and in three weeks I had the seven dollars that I thought would cover the cost of her window. I put the money in an envelope with a note explaining that I was sorry for breaking her window. Then I put the envelope through the letter slot in her door. My soul felt redeemed and I couldn't wait for the freedom of, once again, looking straight into the old lady's eyes. The next day, I. handed the old lady her paper. She thanked me for the paper and said, "Here, I have something for you. " It was a bag of cookies. I thanked her and ate the cookies as I continued my route. After several cookies, I felt an envelope and pulled it out of the bag. When I opened the envelope, I was shocked. Inside was the seven dollars and a short note that said, "I'm proud of you. "
