Little Tom down the street calls our dog "The keep dog". Zip is a sheep dog. But when Tom tries to say " Sheep", it comes out "keep". And in a way Tom is right. Zip is always bringing things home for us to keep! I'll tell you about some of them. Zip's first present was a shoe. It was made of green silk. We didn't know how Zip found the shoe. But after a moment, Mary, my big sister, told me the shoe had a strange smell. I nodded(点头) and held my nose. "What do you think it is?" "It smells like something for cleaning. I think someone tried to clean a spot (污点) off the shoe. Then he put it at the door to dry." Along came Zip. And good-bye shoe!" I said. "We should take it back." "We can't".said my sister. "Maybe little Tom is right," Mary said. "Maybe Zip is a keep dog!"

    It's common knowledge that sleep problems can be caused by things such as stress, anxiety, or even using a smartphone before bedtime. But recently, a team of researchers discovered that genes could also be a cause of sleepless nights.

    The scientists, from Rockefeller University in New York, US, found that delayed sleep phase disorder（DSPD，睡眠相位后移综合症）, a condition that affects one's sleeping patterns, is passed down via a mutated（突变的）gene. DSPD sufferers wake up later and go to bed later than the average person. To come to their conclusion, the team studied a 46-year-old woman who is only usually able to fall asleep at 2 or 3 in the morning. It was discovered that the woman's body produces the hormone that helps her sleep at night up to 7 hours later than regular sleepers. The scientists found this was caused by a mutation in one of the woman's genes, one that helps regulate the “body clock”.

    Some of the woman's family members were also found to share the same mutation—and the same sleeping problems –leading the scientists to believe that sleep troubles are passed down through the generations.

    However, having this mutation doesn't mean you automatically have sleep problems. The team also found two people who had the mutation but reported no problems with their sleep.

    But while this is an interesting discovery, it offers no help to those who can't fall asleep at night—although there are a few things you could try to help you sleep earlier.

    BBC journalist Michael Mosley produced a TV documentary in May in which he talked about his battle with insomnia（失眠）and the techniques he used. “I avoid social media for at least an hour before bed, I do mindfulness exercises, and if I wake up in the middle of the night, I read a book for an hour or so,” he wrote in an article for the Radio Times.

    Youth football team members rescued more than two weeks after sudden flooding trapped them in a cave in Thailand are now being well looked after at a hospital in the northern city of Chiang Rai. In addition to treating the boys for potential body fluid loss, inadequate nutrition and lack of oxygen, their doctors also plan to closely monitor them for symptoms of diseases that may have been infected by animals living in the cave.

    "The next step is to make sure those kids and their families are safe, because living in a cave provides a different environment, which might contain animals that could transmit…disease," said the local hospital. The boys and their family members have been told to watch for symptoms such as headache, nausea(反胃), muscle pain or difficulty breathing, the reports added.

    Yet based on the location where the boys were trapped—more than four kilometers from the cave complex's main entrance, past some fully submerged passages—and the fact they have been swimming out wearing full scuba face masks, it seems unlikely that they were living with bats in the cave or breathed in bat-associated bacteria during their rescue, several infectious disease experts said. "It's hard to imagine bats got that deep into the cave because of all those narrow passageways, but it is possible," says Ian Lipkin, an animal expert and professor at the Mailman School of Public Health at Columbia University. "It's unlikely that there would be many animals in there," notes Jonathan Epstein, a doctor at EcoHealth Alliance, a nonprofit organization that studies diseases and how to prevent them. Bats typically like to rest in areas they can easily enter and exit, not in places that fully flood, he adds.

    Bats in Thailand have been linked with a wide range of viruses that are similar to severe acute respiratory syndrome (SARS)—Lipkin says. But it seems more likely the boys would have been exposed to infection-causing bacteria when they swam through the dirty water with cuts and scrapes. "If you are trying to prioritize issues with respect to health care for these kids, number one would be psychological damage and second will be bacterial infections from the cuts and scrapes they may have encountered." Lipkin says.

    My friend Jason and I wanted to do something to help other people who are less lucky and help us grow at the same time. After we decided that we would volunteer in Nepal, I did some surveys on the Internet and I found an organization called Volunteer(志愿者) Nepal and felt strongly that it was the right choice for us.

    While making our plans, Jason and I realized that others might like the chance to be a part of our experience. So before leaving for Nepal, we asked the people we know whether they would be interested in donating(捐赠) money or goods to Nepal Orphans Home.

    One friend, whose family owns a shop called Drake Supermarket, told others about it. Many people wanted to donate something. We received donations that filled 29 boxes with sporting goods, toys, coloring books, pencils, children's books, and more, The boxes were later taken to Drake's warehouse(仓库) where I prepared them for shipment. Drake agreed to ship them to Nepal for free .

    The boxes had arrived at the Volunteer House when we arrived there. The next day, Jason and I opened the boxes. The children from the orphanages(孤儿院) stood in a line and were able to choose a gift. This took about an hour, but the looks on their faces and the happiness that we saw in their eyes made it one of the best days of our life.

    We visited the orphanages there in the following days. Being with the children at the orphanages was both sad and wonderful. I'm sure that anyone who has volunteered will understand what I mean by that. My experience as a volunteer was very useful. It has changed me as a person and the way I viewed life in the past.

    When "Rise of the Planet of the Apes" was first shown to the public last month, a group of excited animal activists gathered on Hollywood Boulevard. But they weren't there to throw red paint on fur-coat-wearing film stars. Instead, one activist, dressed in a full-body monkey suit, had arrived with a sign praising the filmmakers: "Thanks for not using real apes (猿)!"

    The creative team behind "Apes" used motion-capture (动作捕捉) technology to create digitalized animals, spending tens of millions of dollars on technology that I records an actor's performance and later processes it with computer graphics to create a final image (图像). In this case, one of a realistic-looking ape.

    Yet "Apes" is more exception than the rule. In fact, Hollywood has been hot on live animals lately. One nonprofit organization, which monitors the treatment or animals in filmed entertainment, is keeping tabs on more than 2,000 productions this year. Already, a number of films, including "Water for Elephants," "The Hangover Part Ⅱ" and "Zookeeper," have drawn the anger of activists who say the creatures acting in them haven't been treated properly.

    In some cases, it's not so much the treatment of the animals on set in the studio that has activists worried; it's the off-set training and living conditions that are raising concerns. And there are questions about the films made outside the States, which sometimes are not monitored as closely as productions filmed in the Sates.
