Question: Article: Printing images is easy. Just select an image of a purple robot on your PC, for example, and press print. Your home printer exactly shoots drops of ink onto a flat piece of paper, creating the robot's 2-D image. "Printing" 3-D objects is different. Take the purple robot. First select a file of the 3-D printer. Immediately, the printer begins making noise, and a nozzle releases plastic material in thin layers. In two or three hours, a 3-D purple robot is standing before you. 3-D printing has developed to the point where printers can now create high-quality objects using a variety of materials, including metals. That means 3-D printers can now make final products that meet high industrial standards. 3-D printers are already being used to make parts for racecars and jets as well as man-made limbs and hearing aids. So far, few homes have 3-D printers. That's because 3-D printing is not only new to most people but also quite expensive. To bring 3-D printing to the masses, some retail stores plan to offer the service. For example, the Staples chain of office supply stores has announced that it will offer 3-D printing in Europe beginning in 2013. Customers will be able to submit their own 3-D designs to Staples website for printing. After the job is done, they'll pick up their item at a nearby Staples store or have it mailed to their homes. This service is sure to encourage many more people to try out 3-D printing.

Question: Article: Sushi is a kind of food made with a mixture of cooked or raw fish, vegetables, and rice. Although Sushi is most commonly considered to have its origin in Japan, it actually began in China during the 7thCentury. At that time, any fish caught had to be preserved. Raw fish was cleaned and then pressed between layers of heavy salt. After a couple of months, the whole process was complete. Over time, a discovery was made that by rolling the fish in rice that had been soaked in vinegar the fish was easily fermented in a few days rather than months. The rice was then thrown away and the fish was eaten. However, with a food shortage, people began consuming the rice as well as the fish and thus, Sushi today as we know was born. However, in the 1800s, a famous chef by the name of Yohei created two styles of Sushi--one called Edo, and the second, Osaka, for two cities. Sushi is usually consumed with hot green tea. Also, Gari is offered free and eaten between bites to create a better taste. Two kinds of sauce are usually available: one is soy sauce, which is poured on most kinds of Sushi; the other is a thick sweet sauce used on eel . Sushi has taken the world by storm and today is a multi-billion dollar industry. Its popularity continues to rise because people are looking for healthy food that is quick and easy to make. With such unbelievable popularity as well as the health benefits of eating Sushi, it is likely that this food will continue to be a part of everyday life for many more centuries to come.
