Paying a higher price than usual for a ticket to see a film in 3D is the annoyance of many a cinema-goer's life. But there may be a benefit to doing so, as a study has found that 3D films exercise the brain and improve short-term functioning in a similar way to brain-training tests. The research found that people who watched a movie in 3D improved cognitive   skills, compared to those who watched it in 2D. The research was led by neuroscientist  Dr Patrick Fagan from Goldsmiths University in London. More than 100 people took part in the experiment, where participants watched Disney filmBig Hero 6in either standard format or RealD 3D. They also carried out a brain-training-style test before and after seeing a section from the film. The test covered memory, reaction times and cognitive function and the results were compared later. According to the research, which was carried out in partnership with science group Thrill Laboratory, participants experienced a 23 percent increase in cognitive processing, as well as an 11 percent increase in reaction times. Dr Fagan said that the results showed enough of an improvement in brain function to suggest that 3D could play a part in improving brain power in the future. "These findings are more significant than you might think," he said. "It is a fact that people are living longer and there is a noticeable decline in cognitive brain function in old age which can worsen future quality of life. There has never been a better time to look at ways to improve brain function. The initial results of this study show that 3D films may potentially play a role in slowing this decline." A second part of the experiment involved those watching the film being fitted with headsets that scanned brain activity and this too showed heightened   activity when watching 3D. According to the results, participants were seven percent more engaged with what they were watching, adding to argument that 3D movies are more like watching real-life--something Professor Brendan Walker from Thrill Laboratory...

The Wal-Mart in Cleburne, Texas, was crowded. People were waiting in long lines at checkout counters to pay for small things that would be next-morning treasures under someone's Christmas tree. The woman standing in cashier Jeffrey Kandt's line seemed to be living on the edge of subsistence . Her clothes were worn and her hands were those of a person who'd worked hard for what she had. She held a single item in her arms as she patiently waited to move to the front of the line -- a Sony CD player. She had saved all year for this. With tax, the total would be close to $ 220. As the woman got close to the cashier, she suddenly shouted, "Where's my money? All of my money fro my son's gift! Oh no!" "Why my line?" Kandt thought as he watched the poor woman searching through her clothes. He was going to have to call his manager to avoid the sale but it would mean a long wait for the customers behind her. "I am going to go home late tonight," Kandt thought. Then an amazing thing happened. At the back of the line, a man took out his wallet, pulled out $100 and passed it forward. As the cash moved up the line, a twen5ty-dollar bill was added here, and a ten-dollar bill was added there. When the collection finally reached the registewr, Kandt counted $ 220. Strangers had fulfilled a poor woman's Christmas wish. The poor in his line at the Wal-Mart in Cleburne, Texas, had come together on Christmas Eve, 2002.

To help the environment, many Americans have made the change from paper and plastic bags to reusable grocery bags. But a report by a Florida newspaper says that reusable grocery bags sold by some supermarkets contain high levels of lead . Lead is a metal that can be harmful to humans, especially young children. Now, Senator Charles Schumer is asking the US government to investigate  the use of lead in reusable shopping bags. "When our families go to the grocery store looking for safe and healthy foods to feed their kids, the last thing they should have to worry about is poisonous bags." Schumer said, "A quick investigation will allow everyone to make informed, timely decisions." Schumer added. Lead in the bags is not likely to rub off on food. But over time, paint on the bags can chip and the bags can wear out. When this happens, lead can be released . The Tampa Tribune newspaper said certain bags sold at Publix and Winn-Dixie supermarkets had lead levels that were a concern  to health officials. The affected bags were found in Florida. But Publix has more than 1,000 stores in Alabama, Florida, Georgia, Sough Carolina and Tennessee. Publix says that all of its bags are under current laws about lead content, but that they have asked the makers of the bags to reduce the lead levels in the product. The bags with the highest levels of lead had fancy designs and many pictures. Plain reusable bags without decoration were found to contain little lead. Consumers worried about lead levels in reusable bags can change to cloth or string bags. Paper bags are also a good choice, since paper can be recycled . Since 2007, Publix supermarkets have sold more than 13 million reusable bags. The store says because shoppers have made the change to reusable bags, it has saved more than 1 billion paper and plastics bags. Customers are advised to choose bags   _  . A) with colorful designs B) with fancy pictures C) made of plastic D) made of paper
