Question: Article: The next time you get caught jumping on your bed you can tell your parents with a straight face that you are not playing, simply getting ready got a promising career in "Mattress Jumping". Believe it or not, there are some people who actually get paid to do that! According to Reuben Reynoso, a professional mattress tester at San Francisco's McRoskey Mattress Factory that still makes every mattress by hand, it is real work and needs some training. For a start, it's not all about jumping to new heights or doing tricks like professional athletes, but rather about feeling each area of the mattress carefully to detect the filling. In order to do it right, every bit of the mattress has to be tested slowly and deliberately. Over the years, Reynoso has figured out the perfect routine. He begins by placing a protective mat over the mattress so that it doesn't get dirty or absorb the smell from his feet. Then begins the fun---he steps to the middle of an edge and then takes five steps back and five steps forward. In this way, he slowly but surely, covers the entire surface. The key according to him is to find the perfect number of jumps---Too many and he will end up destroying the mattress completely. Too few? And it will not fit into the giant machine for that final sewing! Who knew a job that sounds so simple could have so many skills! While Reuben will not reveal how he got into this profession, he will admit that it is more fun than being a carpenter, roofer, construction worker and railroad engineer---all jobs he has tried previous to finding his true profession!

Question: Article: Pottery is the name given to all kinds of useful or artistic objects made from clay. Pottery can be plates or water pots or baskets. Pottery can be large or small, fancy or plain. Pottery is part of the large family of ceramics .Ceramics are synthetic materials. For example, bricks and tiles are both ceramics. How is pottery made? First, a potter takes some clay. Clay is a soft, red material from the earth. It looks a little like red dirt, but it's very different. Clay is thick and rich. Wet clay can be worked into any shape. When the clay dries, it will keep that shape. The potters takes some clay and pushes and squeezes it until it is soft and smooth. After that, the clay can be shaped into anything. There are several ways to shape clay. Sometimes potters use their hands. Sometimes they use a special wheel. They place the clay in the center of a round, flat wheel. The wheel moves very fast, and the potter shapes the clay. After the potter has shaped the clay, it can be decorated . Potters use glaze, which is a kind of paint, to decorate their work. Some glazes are very simple. Other glazes have beautiful colors and designs. The glaze is not just beautiful. It is also useful. The glaze makes the pottery smooth and waterproof. Potters also make some decorative lines and designs on the surface. After it is decorated, the clay must be baked, or fired, in a special oven. Baking the clay at very high temperature makes it hard and strong. Firing also makes the glaze stick to the pottery. When the firing is over, the potter carefully removes the pottery from the oven and lets it cool slowly. If it cools too quickly, it could crack and break. Since pottery is waterproof, it is very popular for dishes. You can find examples of pottery in almost any home. But pottery can also be found in museums. Some pieces of pottery are valuable and beautiful pieces of art.

Question: Article: Researchers are now using 3D printing to create models of the human heart to help heart specialists. The heart doctors can use the models to better help patients before an operation. Dr. Bramlet, a children's heart expert at the University of Illinois College of Medicine, says the 3-D models show information he cannot get any other way. "And so what we've done with the printed models? We've pulled it out of the screen so that you can actually hold it in your hand and evaluate the anatomy ." A 3-D printer uses images from a digital display to create a physical model of a human heart. Matthew Bramlet says doctors can use the model to understand the anatomy. Pictures from medical tests like CAT scan or MRI are sent to a 3-D printer to create a heart in a plaster form. The printer then constructs the heart, thin layer by thin layer. Dr. Bramlet says the model matches the real heart in every detail. "When we're done with the model and made our decision, we want to be able to go back to the source image and confirm those findings," he says. Dr. Bramlet has built model hearts for different kinds of heart operations. All of the operations were successful. In his first case, digital images showed only one tiny hole in a baby's heart. But, the 3-D printed model showed several defects or problems that the baby was born with. Dr. Bramlet says those defects could not be seen easily in the images. The heart surgeon was able to change the type of surgery for the patient based on the 3-D model. He added that 3-D heart models saves time during heart operations. Kathy Magliato is a heart surgeon at Saint John's Health Center in Los Angeles. She welcomes the new technology. She says it could help her make better decisions before she operates on the hearts of her patients. "I can then take this very complicated structure before the operation and I can hold it in my hand and plan an operation around what I'm seeing, touching and feeling. That to me is what can potentially change the game in an operation and save lives." Dr Bramlet continues to research the technology. He is working with the National Institutes of Health to build a 3-D library that includes heart models and images that others can use.
