According to body language expert Robert Phipps, the way people sleep at night actually determines a lot about the type of personality they have. Phipps has identified four sleeping positions that affect personality.

    Phipps found that worriers, those who stress the most, tend to sleep in the fetal (胎儿的) position. He found that this is the most common bedtime position, with nearly 58 percent of people sleeping on their side with knees up and head down. The more we curl up (蜷曲), the more comfort we are seeking, according to Phipps.

    The second most common position is the log. Sleeping with a straight body, with arms at each side, as if they are standing guard at Buckingham Palace, indicates stubbornness, and these people (the 28 percent who sleep this way) often wake up stiffer than when they went to sleep.

    “The longer you sleep like this, the more rigid your thinking is and you can become inflexible, which means you make things harder for yourself,” according to Phipps.

    Yearner (向往) sleepers are next on the list. About 25 percent of people sleep in this style—on their side with arms stretched out in front, looking as if they are either chasing a dream or perhaps being chased themselves. Yearners are typically their own worst critics, always expecting the best results, explained Phipps. These people often wake up refreshed and eager to face the challenges of the day ahead.

    Perhaps the most peculiar (奇怪的) of sleep styles is the freefaller position. This sleep style makes up 17 percent of the population. They sleep face down with arms stretched out. These people, according to Phipps, feel like they have little control over their life. Not only is this the strangest of sleep styles, but also the least comfortable, and people may wake up feeling tired and have no energy.

    Inconclusion, Phipps has only one more thing to add: “A good night's sleep set you up for the following day and our sleeping positions can determine how we feel when we wake.”

    Chinese scientists recently have produced two monkeys with the same gene, Zhong Zhong and Hua Hua, using the same technique that gave us Dolly the sheep. These monkeys are not actually the first primates（灵长类）to be cloned. Another one named Tetra was produced in the late 1990s by embryo（胚胎）splitting, the division of an early-stage embryo into two or four separate cells to make clones. By contrast, they were each made by replacing an egg cell nucleus（原子核）with DNA from a differentiated body cell. This Dolly method, known as somatic cell nuclear transfer（SCNT）, can create more clones and allows researchers greater control over the edits they make to the DNA.

    Success came from adopting several new techniques. These included a new type of microscopy to better view the cells during handling or using several materials that encourage cell reprogramming, which hadn't been tried before on primates. Still, the research process proved difficult, and many attempts by the team failed. Just two healthy baby monkeys born from more than 60 tested mothers. This leads to many researchers' pouring water on the idea that the team's results bring scientists closer to cloning humans. They thought this work is not a stepping stone to establishing methods for obtaining live born human clones. Instead, this clearly remains a very foolish thing to attempt, it would be far too inefficient, far too unsafe, and it is also pointless.

    But the scientists involved emphasize that this is not their goal. There is now no barrier for cloning primate species, thus cloning humans is closer to reality. However, their research purpose is entirely for producing non-human primate models for human diseases; they absolutely have no intention, and society will not permit this work to be extended to humans. Despite limitations, they treat this breakthrough a novel model system for scientists studying human biology and disease.

    Kung fu is one of the most popular topics of discussion among foreigners talking about China. As a discipline of kung fu with the largest number of practitioners in China, Tai Chi is gaining popularity worldwide. Tai Chi is sweeping the world thanks to its deep cultural roots and the health benefits coming from practicing it.

    The philosophy of Tai Chi features the concept of yin and yang, which is typical of Confucianism and Taoism. Tai Chi also takes in ideas from traditional Chinese medicine, including anatomy (解剖学) and physiology (生理学). It is a practice that couples hardness with softness, and it is a perfect example of traditional Chinese culture.

    Through lasting practice, learners begin to feel the positive impact (影响) of Tai Chi on their health. Unlike kung fu practices that focus on attacking and defending against enemies, Tai Chi focuses more on shaping good characters and keeping fit. By practicing Tai Chi, people will feel an improvement in their physical and psychological health by promoting a balance between yin and yang within their bodies. This is similar to Western medicine's improving people's self-healing ability and immune system.

    Tai Chi is playing an important role in presenting Chinese culture to the rest of the world, acting like a bridge between China and other countries. Recent years have seen a lot of international communication on Tai Chi. In provinces like Hebei, Henan, Shanxi and Shaanxi, where Tai Chi teaching and learning are particularly active, local governments and non-governmental institutions often organize activities and competitions for learners and fans to attend and participate in. Large sporting events hosted by China such as the Asian Games and Olympics have featured Tai Chi performances or contests. These activities have opened a window for the outside world to know more about Tai Chi, paving the way for its overseas wide spread.

    Today, Tai Chi not only belongs to China, but also to the whole world and to everyone who loves it.

    Most high school students would rather spend their summer vacations far away from the classroom. But Vineet Kosaraju and Nikhil Cheerla are choosing to go back to school, and this time they are the teachers.

    "I think it's really nice that I can help the community by spending just a little bit of time every week helping just a few students here and there try and learn programming," Kosaraju said.

    Friends since they were young boys, Kosaraju and Cheerla always shared a love of computer science. They learned the skills from their parents and school, but recognized that not all children have that chance.

    "Programming isn't taught in that many schools, especially low income (收入) schools, because there isn't that much money to support it," Kosaraju said.

    So he and Cheerla developed "Math and Coding," an after-school program for kids of all ages to learn the basics of computer programming.

    Between applying for college and doing their own homework, the two boys now spend a few hours every week going to different libraries teaching classes that cover everything from building basic games to developing apps.

    The friends started the program a little over a year ago and already, it's spread to more than a dozen libraries across the Bay Area in California. They are even training volunteers to teach these very same classes in other US states and Canada.

    Maryann Mitchell brought her 8-year-old granddaughter, Gabriella, to a class on coding at the Alum Rock Library in San Jose, California.

    "It's a chance for her to learn," Mitchell said. "It's the way of the future, and it's a good way for her to get grounded and be ready for what the future holds."

    "I think the most rewarding thing is having people come up and thank you and say they really learned a lot from this class," Cheerla said. "It doesn't get any better than that."

    I read somewhere that we spend a full third of our lives waiting. But where are we doing all of this waiting, and what does it mean to an impatient society like ours? To understand the issue, let's take a look at three types of "waits".

    The very purest form of waiting is the Watched-Pot Wait. It is without doubt the most annoying of all. Take filling up the kitchen sink(洗碗池) as an example. There is absolutely nothing you can do while this is going on but keep both eyes fixed on the sink until it's full. During these waits, the brain slips away from the body and wanders about until the water runs over the edge of the counter and onto your socks. This kind of wait makes the waiter helpless and mindless.

    A cousin to the Watched-Pot Wait is the Forced Wait. This one requires a bit of self-control. Properly preparing packaged noodle soup required a Forced Wait. Directions are very specific. "Bring three cups of water to boil, add mix, simmer(用文火炖）three minutes, remove from heat, let stand five minutes." I have my doubts that anyone has actually followed the procedures strictly. After all, Forced Waiting requires patience.

    Perhaps the most powerful type of waiting is the Lucky-Break Wait. This type of wait is unusual in that it is for the most part voluntary. Unlike the Forced Wait, which is also voluntary, waiting for your lucky break does not necessarily mean that it will happen.

    Turning one's life into a waiting game requires faith and hope, and is strictly for the optimists among us. On the surface it seems as ridiculous as following the directions on soup mixes, but the Lucky-Break Wait well serves those who are willing to do it. As long as one doesn't come to rely on it, wishing for a few good things to happen never hurts anybody.

    We certainly do spend a good deal of our time waiting. The next time you're standing at the sink waiting for it to fill while cooking noodle soup that you'll have to eat until a large bag of cash falls out of the sky, don't be desperate. You're probably just as busy as the next guy.
