Scientists investigated why Ebola virus is so deadly when it spreads from animals to humans and then from human-to-human contact. The research team looked at the Zaire Ebola virus in an animal system to understand how it gains strength. This virus is responsible for the current outbreak in West Africa. They found that initially the animal systems were not affected by the virus, but succeeding transmission(传送) into other animals caused the virus to “hot up” and become more severe.

    The team analyzed the viruses at different stages and were able to identify several changes in its genetic material that were associated with increased disease.

    Professor Julian Hiscox, who led the study from the University's Institute of Infection and Global Health, explains: “The work tells us that the evolutionary goal of Ebola virus is to become more fatal.”

    “We were able to show through genetic analysis which parts of the virus are involved in this process. The information we have gathered will now allow us to monitor for such changes in an outbreak as well as develop future treatment strategies.”

    Professor Roger Hewson, leading the study from Public Health England, Porton Down, said: “Ebola virus is such a destructive infection to the people affected by the disease and the economy of West Africa.”

    “Our understanding of Ebola virus biology is way behind that of other viruses and our cooperation shows how we can bring together our specialists' skills to close this knowledge gap.”

    Professor Miles Carroll, a co-author of the work, said: “This study has allowed the team to be at the forefront of developing methodologies to analyze patient samples recently taken by the European Mobile Laboratory from West Africa to understand disease evolution during the current outbreak.”

    One day when I was 12, my mother gave me an order: I was to walk to the public library, and borrow at least one book for the summer. This was one more weapon for her to defeat my strange problem—inability to read.

    In the library, I found my way into the “Children's Room.” I sat down on the floor and pulled a few books off the shelf at random. The cover of a book caught my eye. It presented a picture of a beagle. I had recently had a beagle, the first and only animal companion I ever had as a child. He was my secret sharer, but one morning, he was gone, given away to someone who had the space and the money to care for him. I never forgot my beagle.

    There on the book's cover was a beagle which looked identical (相同的) to my dog. I ran my fingers over the picture of the dog on the cover. My eyes ran across the title, Amos, the Beagle with a Plan. Unknowingly, I had read the title. Without opening the book, I borrowed it from the library for the summer.

    Under the shade of a bush, I started to read about Amos. I read very, very slowly with difficulty. Though pages were turned slowly, I got the main idea of the story about a dog who, like mine, had been separated from his family and who finally found his way back home. The dog was my dog, and I was the little boy in the book. At the end of the story, my mind continued the final scene of reunion, on and on, until my own lost dog and I were, in my mind, running together.

    My mother's call returned me to the real world. I suddenly realized something: I had read a book, and I had loved reading that book. Everyone knew I could not read. But I had read it. Books could be incredibly wonderful and I was going to read them.

    I never told my mother about my “miraculous” (奇迹般的) experience that summer, but she saw a slow but remarkable improvement in my classroom performance during the next year. And years later, she was proud that her son had read thousands of books, was awarded a PhD in literature, and authored his own books, articles, poetry and fiction. The power of the words was held.

    Want to enjoy the sights while you're eating? Try the Top of the World restaurant. At about 244 meters above Las Vegas, diners can enjoy a spectacular view of Las Vegas in this revolving restaurant. However, the real adventure starts at the end of the meal. That's when the customers are taken from their seats at ground level to the observation rooms in elevators that travel at a remarkable speed.

    A Theatrical Experience

    An Unusual Setting

    Don't care about presentation? You'll be fine at the Modem Toilet restaurant in Taiwan. The theme of this restaurant is the toilet, and you would be surprised how many people queue up for the experience of eating on toilet seats.

    You might not get what you wish for, but you always get what you work for. I want to be a professional ballerina(芭蕾舞者) with the American Ballet Theatre in New York when I grow up, and I work toward my dream by training over 18 hours a week. I even started homeschooling so I could make more time for dance. I love dancing more than anything. It makes me feel strong and invincible(不可战胜的), like nothing could ever bother me. Most important, it's helped me deal with the most difficult event of my life — the death of my dad when I was seven.

    My dad died of a heart attack while playing hockey, his favorite sport. When my mom first told me, it didn't hit me that I would never be able to see him again. It was also hard to tell my friends and classmates because I didn't know what to say, and they never knew how to respond. But four years later, everything that I do, I do in memory of my dad. I did my first dance solo. “The Love Lives On.” to him when I was nine.

    I would have never gotten through the experience without my mom. She comforted me when I was in grief and pain, and we wrote down all the memories I had with my dad in a special book. Now that I'm older, my mom and I do get on each other's nerves more often — for a while, my schedule was very busy and we were so stressed that our little miscommunications would rise into huge arguments. But after we attended counseling(心理咨询) and I started homeschooling, things got much better, and now my mom and I have more quality time to spend together.

    I've learned that talking and communicating are the most important things to do in any relationship, and that definitely includes friendships, too! When I hang out with my friends, I try not to look at my phone. It's so awkward(尴尬的) when you're sitting at a table with someone else, and she's texting instead of talking to you. I think a good friend is kind, respectful, fair, and funny — and I'll always try to be all of these things in person, not just on the phone!

    It was when I was walking to my office, trailed by three young people whose ages ranged from 16 to 25, flowing down the corridor behind me like the tail of a kite, that I thought of it for the first time.

    This could be because I am not actually a mother. Until recently, I was not a "real" stepmother either. But I have been living with the man who is now my husband, Bernardo for 10 years and in those 10 years, not only have his younger daughters spent every other weekend and half of their school holiday with us but also his son has lived with us full-time. In fact, when Bernardo asked me to move in, he asked his son for permission first.

    Being a step mum is hard enough but being a sort-of-step-mother is about the most awkward position a mature woman can find herself in. With my sort-of-steppies, I have occupied a place of influence, power and sometimes extreme anger by turns. I have stepped on a delicate path between being a grown-up friend, a bridge of influence with their father, the woman of the house, and a figure of authority – but not too much.

    Love the kids or hate them, you must always remember that no matter how much you cook, clean, hug, comfort and discipline, you will never actually count.

    To survive, I trained myself to love the stepkids as hard as I could, but not to care. It's a handy piece of good mental health trickery I recommend to anyone in my position. I can help with homework, yes, but not bother about the results of that homework. I can teach them good manners, but not care about the bad habits they learn at home. Semi-detached is the position.
