Q: Article: Years ago, the American writer Kurt Vonnegut often said there was one story that would always make a million dollars: Cinderella. In Hollywood and in today's economy, it is more like $70 million and that is just a start. "Cinderella" made that amount in ticket sales when it opened last weekend. But the merchandising deals linked to the movie are also hugely valuable. So the artistic success of the film is open to debate. What is clear, however, is the movie's business success. It is a hit in the theaters but it is also a hit in retail  . And Disney widened its usual market for "Cinderella" products. There are products connected to the Disney film targeted not only at little girls, but women, too. For example, the famous shoe designer Jimmy Choo partnered with Disney to create a version of Cinderella's "glass slippers" or shoes. You can buy them for about $5,000. At that price, you would not want to lose one at the ball, even if that is the way you get your prince. Several other shoemakers also accepted Disney deals to design versions of the famous footwear. The makeup company MAC quickly sold all its products with official links to "Cinderella." But lucky buyers were soon selling the products on the online marketplace eBay for many times the original price. HSN is a popular television and online retailer   of jewelry, clothing and objects for the home. The marketer is now an exclusive seller of "Cinderella" products. So, is there anything left for the children, those people we think of as the traditional audience for the age-old fairy tale? Yes, you can find toys and other children's products at the American retailer JC Penney. Of course, you can also visit a Disney store. Disney also produced an animated version of "Cinderella." It came out in 1950 and is considered a classic. Which do you think the Disney company does better: live action   or animated films? Post your thoughts in the comments section.

Q: Article: How the Grand Canyon   was created remains one of the geology's greatest mysteries. Some evidence suggests that the process was a gradual one in which the Colorado River (which runs through the canyon) slowly cut deeper and deeper into the ground over millions of years. But volcanic rock samples taken from the canyon now suggest that the canyon was down-cut instead. Down-cutting is when a flood of water rushes over a landscape   with enough force to cut deeply into the ground and leaves behind a canyon. Such a flood is usually released when a natural or man-made dam   bursts. Robert Webb, a research geologist, says natural dams seem to have formed and broken across the Colorado River several times during the last million years. The dams were built when lava  from the eruptions of nearby volcanoes flowed into the river. The lava hardened into hard rocks and blocked the river, causing it to back up and form a lake. Each time the lake grew so huge that it broke the rock dam, releasing a flash flood that furthered the down-cutting process and deepened the canyon. Down-cutting is not just an earthly event. Satellite photos sent back from Mars suggest that the process has happened there, too, say many other researchers. The photos, taken by the Mars Global Surveyor, indicate that an enormous lake existed on Mars 3.5 billion years ago. The lake spilled into a large nearby hole. One edge of the hole broke, releasing a flash flood that quickly carved out a grand canyon. The existence of down-cutting on Mars is just one more piece of evidence that the cold, dry planet was once warm and wet.
