    Food is extremely important to us human beings and rice is one of the main food in the world. Australian researchers have discovered a way to genetically engineer rice which would provide significant health benefits to more than half the world's population.

    A study undertaken at the University of Tasmania, published in a respected journal of the National Academy of Sciences, discovered a method to increase the resistant starch (抗性淀粉）content in rice, making it more digestible and leading to lower rate of diabetes (糖尿病）and overweight.

    Steven Smith, the lead author of the study and a foreign expert for the Chinese government who has been appointed to work on crop improvement projects by the Chinese Academy of Sciences, said increasing the higher resistant starch content gave this “designer” rice many added health benefits. “We have discovered that we can increase the amount of resistant starch in cooked rice, which could provide health benefits for a large number of people in Asia and beyond,” Smith said in a media release on Friday. “The same approach can be adapted for use in other cereals, including wheat. Not only can it have benefits for diabetes and obesity, but also for disorders of the bowel(肠）including cancer.”

    Rice is the main food for more than half the world's population, providing much of the world with most of their calories. Smith said that as the rate of diabetes and obesity in Asian countries continued to grow, his “designer” rice could provide a way to limit health problems.

    “Not only does resistant starch reduce the possibility of a 'sugar hit' but it also reduces the appetite and promotes the growth of the healthy germs.” Smith said.

Smith divides his time between the University of Tasmania and his research lab in Beijing where he hopes to make significant advance in sustainable (可持续的）living.

    Downloading music over the Internet is pretty common among high school and college students. However, when students download and share copyrighted music without permission, they are against the law.

    A survey of young people's music ownership has found that teenagers and college students have an average of more than 800 illegally copied songs each on their digital music players. Half of those surveyed share all the music on their hard drive (硬盘), enabling others to copy hundreds of songs at any one time. Some students were found to have randomly linked their personal blogs to music sites, so as to allow free trial listening of copyrighted songs for blog visitors, or adopted some of the songs as the background music for their blogs. Such practices may be easy and free, but there are consequences.

    Sandra Dowd, a student of Central Michigan University, was fined US $7,500 for downloading 501 files from Lime Wire, a peer-to-peer file sharing program. Sandra claimed that she was unaware that her downloads were illegal until she was contacted by authorities. Similarly, Mike Lewinski paid US $4,000 to settle a lawsuit（起诉）against him for copyright violation (违反). Mike expressed shock and couldn't believe that this was happening to him. “I just wanted to save some money and I always thought the threat was just a scare tactic(战术).” “You know, everyone does it,” added Mike.

    The RIAA （Recording Industry Association of America）, the organization that files lawsuits against illegal downloaders, states that suing (控告) students was by no means their first choice. Unfortunately, without the threat of consequences, students are just not changing their behavior. Education alone is not enough to stop the extraordinary growth of the illegal downloading practice.

    Government in Tibet have denied the permanent( 永久的) closure of Mount Qomolangma National Nature Reserve.

    The announcement came after a report went viral online claiming the base camp of the world's highest mountain was "permanently closed due to heavy pollution" and caused a universal misunderstanding.

    Mount Qomolangma National Nature Reserve was set up in 1988. Covering an area of more than 33, 800 square km, it is home to one of the world's most weak ecosystems(生态系统).

    Kelsang, deputy director of the reserves administration, said ordinary tourists are allowed to visit areas around Rongpo Monastery, almost 5,000 meters above sea level. As for travelers who have a climbing permit, they can go to the base camp at an altitude of 5,200 meters. The mountaineering activities have been permitted by the regional forestry department.

    To conserve the environment surrounding Mount Qomolangma, China carried out three major clean-ups at an altitude of 5, 200 meters and above last spring, collecting eight tonnes of household wastes, human wastes and mountaineering trash. This year, the clean-up will continue, and the remains of mountaineering victims(受害者) above 8,000 meters will be centrally dealt  with for the first  time. Meanwhile, the number of people who stay at the base camp will be kept under 300.

Recently, there are 85 wildlife protectors in the reserve, and 1,000 herders have part-time jobs going around and cleaning up garbage.

These measures aim to strike a balance between various demands such as environmental protection, local poverty relief, mountaineering and education, said Wang Shen, county chief of Dingri at the mountain foot.

    It is commonly believed that in medieval France, New Year was celebrated on 1 April. Then in 1562, Pope Gregory introduced a new calendar for the Christian world, changing New Year to 1 January. With no modern communications, news travelled slowly and new ideas were often questioned. Many people did not hear of the change, some merely forgot, and others chose to ignore it. These people were called fools. Invitations to non-existent "New Year" parties were sent and other practical jokes were played. Over time playing tricks on 1 April became a tradition. The custom eventually spread to England and Scotland, and it was later transported across the Atlantic to the American colonies (殖民地) of the English and the French. April Fools' Day has now developed into an international festival of fun, with different nationalities celebrating the day in special ways.

    France and Italy

    In France and Italy, if someone plays a trick on you, you are the "fish of April". By the month of April fish have only just hatched and are therefore easy to catch. Children stick paper fish to their Friends' backs and chocolate fish are found in the shops.

    America and Britain

    Today, Americans and the British play small tricks on friends and strangers alike on 1 April. A common trick is to point to a friend's shoe and say "Your shoelace (鞋带) is untied." When they look down, they are laughed at. Schoolchildren might tell a friend that school has been cancelled. Sometimes the media get involved. Once, a British short film was shown on April Fools' Day about spaghetti farmers and how they harvest their crop from spaghetti trees!

    Scotland

    In Scotland, April Fools' Day lasts for two days! The second day is called "Taily Day" and tricks on this day involve the bottom (or the "tail", in informal speech). Often a sign saying ‘kick me' is stuck onto someone's back without them knowing.

    If you make a list of the top ten most challenging jobs in the world, chances are that being a teacher will not make the cut. Let's think about their complex task millions of educators face each day as they try to teach a group of often unfriendly, disorderly kids into intelligent, well-rounded individuals. That surely has to be the toughest job in the world, especially taking into consideration that there is no promotion waiting for them even if they are wildly successful!

    What if these all-important individuals that we often take for granted disappear from our lives? That was what Project Ed and Participant Media's teaching campaign asked filmmakers of all ages to envision for their recently-held contest.

    Their short films were called "A World without Teachers", whose intention was to inspire more young people to become teachers. However, the 62 amazing video submissions (提交物) also serve as a reminder of how terrible things would be if we didn't have these selfless individuals guiding us through life. What was interesting is that even the youngest contestants didn't accept the idea that there's no person to tell them what to do.

    High-school student Savannah Wakefield considered if art as we know today would have been different without teachers. Would C. Monet have discovered his talent for impressionism?

    Miles Horst won the 1,000-dollar prize for the best adult submission, lie pictures n world where teachers are replaced by a "brain box". Youth group winner Marina Barham's video describes a fact we all know but often forget. Teachers don't just teach; they inspire—something that no electronic device, no matter how smart, can do!

    So the next time you think your teacher is being "troublesome" for trying to channel you in the right direction, imagine a life without him/her.
