The oddness of life in space never quite goes away. Here are some examples.

    When I was younger, I was too shy to the point where I could not even make eye contact（接触）with people I didn't know. If someone greeted me in the hallway, I would lower my head and hurried passed.

    Funnily enough, this would not have been such a big deal if I had connected with their values and interests. However, everyone in my school was much wealthier than me, and focused on partying and fashion which were contrary to my interests. Although I had a few acquaintances（熟人）, no one seemed to understand me, unable to share my sometimes dark humor and interest in science fiction.

    Halfway through ninth grade, I was once again thrown into a school of strangers. Making friends was difficult, and I sat alone at lunch for the rest of the year. In tenth grade, however, I took part in my school's theatre program, where I met some of my closest friends. The theatre forced me to overcome my shyness and taught me to speak up for myself. Furthermore, pretending to be someone else gave me a sense of previously unknown confidence.

    Although I have a lot going for me right now, I will never forget the struggles I had to overcome when I was younger. This is why, whenever I see someone struggling or standing by themselves, I always invite them to sit with my friends and me. I may not be able to give them my full attention all of the time, but the main point is to let them know someone recognizes their existence and is willing to connect with them.

    Asia can boast(吹嘘) that it has some of the best beaches in the world. Sihanoukville, Cambodia is a seaside town located 200km or a four­hour bus ride away from the country's capital, Phnom Penh. With several beaches and small offshore islands, it is definitely not a place to miss out if you are intending to visit Angkor Wat, as the beaches there are stunning and still unspoiled by mass tourism.

    Serendipity Beach

    Serendipity Beach is the most popular beach for the masses, since it is the most accessible beach, being the nearest one from the main town area. There are plenty of bars scattered around the beach, so be prepared for the crazy parties every night.

    Ochheuteal Beach

    Ochheuteal Beach is located south of Serendipity Beach, and it's a bit of an improvement from Serendipity Beach itself in terms of the people that go there. Over here, there are bars and pubs, but at night, don't expect wild parties like at the Serendipity Beach area.

    Otres Beach

    All the way down south, near Moat Peam, lies a hidden gem called Otres Beach. This is where you can get your yoga suit on and practice meditation(冥想). This is the quietest beach in Sihanoukville and it is the least crowded, with very few parties. If your idea of a beach holiday is just yourself and the sun, sea and sand, this place is for you.

    Koh Rong

    Koh Rong is an island off Sihanoukville that is covered with beautiful sandy beaches. True relaxation lies at Long Beach, which is located on the other side of the island. Clear water surrounds the beach, and once you get there, you'll be greeted with fine white sand.

    Koh Rong doesn't have any roads, so there are no cars or motorbike rentals — everything is mostly on foot.

Emilia Dobek traces her interest in space and the universe back to third grade when she and her father watched a blood moon—a total lunar eclipse (月蚀)—on the roof of their house.

    Now a seventh-grader at East Prairie Elementary School, Dobek recently won the national Discovery Education Lockheed-Martin Beyond Challenge by designing a space station for travelling to Mars.

    She says that night watching the lunar eclipse started a strong desire in her that has yet to run out of fuel. So when her teacher Andrea Smeeton received information about the national challenge, Smeeton said she immediately had one student in mind.

    "I knew she would love the challenge and that she would go way beyond in her search," Smeeton said. "She immediately started researching bone density (密度) of astronauts and how to have food on Mars."

    "My design will ensure the safety of the astronauts but also make sure their comfort is out of this world," Dobek says.

    Dobek's design calls for building the MSS or Mars Storage Station to put the supplies in. It also includes the SGF or Self-Crowing Farm, and she details how it would work with the elements on Mars.

    Then there is physical and leisure activity for the astronauts under Dobek's design. A simulation (模拟装置) allows astronauts to choose their exercise machine and virtual (虚拟的) reality environment. Rooms have circular ceilings so astronauts will be able to watch downloaded shows and even see places on Earth, such as their homes.

    "I want to tell other kids to follow their passions." Dobek said. "Whatever they want to do they should push for it and always try their best."

    After photographer Monni Must's daughter Miya died, the sad mother adopted her black dog, Billy Bean. As Billy became increasingly weak, the thought of its dying was just more than Must could handle. So she decided to clone the dog. “I feared everyone was going to forget Miya," she said, "and my other daughters thought I had completely lost my mind."

    Billy's cells were shipped to ViaGen Pets, a Texas company that provides the cloning service. With more than $50,000, Must picked up a new puppy. "The dog has a real soul and is everything my daughter was—fun, social and kind," she said. "I feel that I still have that touchable connection and not just a spiritual connection.”

    Cloning animals is hardly new. But the recent news that singer Barbra Streisand had cloned her dog grabbed international headlines. People for the Ethical Treatment of Animals(PETA) president Ingrid Newkirk issued a statement saying she would love to talk her out of cloning, noting that millions of wonderful dogs are getting old in animal shelters every year or dying in terrifying ways when abandoned.

    Normally, a doctor takes a tissue biopsy(组织活检), a piece of skin and muscle about the size of a pencil eraser, from the dog. The next step is to take an egg cell from a donor dog, remove the egg's nucleus, and insert DNA from the pet to be cloned. When an embryo(胚胎)develops, it is transplanted in the body of a mother dog.

    In the basic cloning procedure, scientists take an entire adult cell and put it into an egg that's been relieved of its own DNA. The resulting embryo is a clone. However, in many animals, only one in 100 cloned embryos ever leads to a live birth. Some embryos die in the IVF dish or in the mothers bodies. Of those that are born, a few suffer from abnormalities and quickly die. Besides, pet cloning doesn't mean copying everything of your beloved pets.

Let's face it. No one drinks diet sodas for the taste. People drink diet sodas in the hope that it will help them lose weight or at least keep them from gaining it. Yet it seems to have exactly the opposite effect, according to a new study.

Researchers from the University of Texas said those who drank two or more diet sodas a day had waist size increases that were six times greater than those who didn't drink diet sodas. "What we saw was that the more diet sodas a person drank, the more weight they were likely to gain," said Sharon Fowler.

The study was based on data from 474 participants in a large, ongoing research project, where the participants were followed for nearly 10 years.

While the findings are surprising, they also offer some explanations.

Nutrition expert, Melanie Rogers, who works with overweight patients in New York, has found that when patients are switched from regular to diet sodas, they don't lose weight at all. "We weren't seeing weight loss necessarily, and that was confusing to us," said Rogers.

So why would diet soda cause weight gain？No one knows for sure yet, but it could be that people think they can eat more if they drink diet sodas, and so over﹣compensate (补偿) for the missing calories.

A related study found some sweeteners (甜味剂) raised blood sugar levels in some mice. "Data from this and other potential studies suggest that the promotion of diet sodas and artificial sweeteners may be risky," said Helen P. Hazuda, professor at the University of Texas's school of medicine." They may be free of calories, but not of consequences. "
