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.”

Murcia

    I have spent about 8 months living in Murcia and I feel that I should put it as number one on my list. On my return from exploring other cities, I always feel like I'm returning home when I set foot in Murcia. The city centre is full of life and energy and has an incredible atmosphere all year round. Although the accent takes you a little time to get used to at first, you will adjust to it. Murcia is also home to some gorgeous(壮丽的) beaches and amazing coastal views. So it really does have the best of both worlds!

Gibraltar

    I visited Gibraltar during the Easter holidays and I was totally surprised by the beauty of Gibraltar! From a short cable car riding up to the top of the rock you are met with splendid views over the coast and the adorable monkeys which curiously come to greet you on your arrival. Make sure to hide all your food because they think it's a gift for them!

Valencia

    Valencia is beautiful. It's as simple as that! The river-area is so exciting and full of life, all the way up to the science museum and beaches. However, I was a little confused by the fact that the river had long been filled in and turned into a park, yet people still referred to it as The River.

Alicante

    I have spent many a weekend in Alicante, making the most of the beautiful beach in low season, before all the tourists arrive. May is the high season here, so I'd definitely recommend a visit in April, September, or October, just before or after the holiday season.

    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!

    From roller coasters to adventure tours performances to experiments, there are plenty of exciting attractions in the UK. Here is our pick of the best attractions that children can visit.

    The Natural History Museum

Why go: This really is the grandfather of all London museums—the beauty of the building and the amazing exhibits. Look out for the whale skeleton(骨架) occupying the entry hall, but don't miss the largest piece of gold (or a model of it) in the minerals gallery. You can easily spend a day here—tasty steaks, sandwiches and pizzas. Try to avoid weekends, because the crowds are larger

    Best for: Children aged 5 and over. If time is limited, families should go quickly and directly towards the dinosaur gallery, because it's really wonderful.

    Details: Entry is free, although there is a charge for some temporary exhibitions

    Legoland

    Why go: Some 80 million Lego bricks have gone into the creation of this colourful park. There are thrilling rides and countless ways to spend money in shops. Yes, the queues can be long (unless you pay extra for the queue-jumping equipment, which is useful though it does not cover all rides)

    Best for: Legoland is aimed at children under10s, with pre-schoolers particularly well catered for in Duplo Valley

    Details: ￡32 per person; under 3s go free. 25 per cent discount for booking online more than seven days in advance.

Warner Bros. Studio Tour London —The Making of Harry Potter

    Why go: You've read the books, you've watched the films, but no Harry Potter fan will want to miss the chance to go behind the scenes at the film studios where all eight of the movies were made. Sharing the secrets behind the most successful film series of all time and yet still managing to keep the sense of magic alive, this studio tour gives visitors access to two locations filled with original sets and costumes

    Best for: Children aged 7 and over, and anyone with an interest in filmmaking

    Details: ￡39 adults; ￡31 children; under 4s go free

In San Francisco,a large group of sea lions move themselves out of the bay waters and hang out on PIER 39, which is a popular tourist destination. According to dock（码头） officials, this is the most sea lions seen in the region in 15 years.

"Over 1,000 sea lions have been counted this week," PIER 39 harbor master Sheil a Chandor told many different medias. "The increase in sea lions is usually a good sign of their strong population and healthy living environment," said Adam Ratner, Director of Conservation Engagement at the Marine Mammal（海洋哺乳动物） Center in Sausalito, California.

"California sea lions are sentinels（哨兵） of the ocean," Ratner said. Their population to some extent reflects the health of the ocean. Therefore, seeing a large number of California sea lions is clearly a good thing.

For nearly 35 years, the animals have been a star attraction for visitors. That autumn in 1989, PIER 39 had just been repaired, but the ships had not yet been moved back. At that moment, the sea lions' unexpected arrival not only attracted fans but also created enemies. According to a website, some dock residents and workers were scared away by the strong and very unpleasant smell and noise of their new neighbors, while others saw these animals as a bright spot after the destructive Loma Prieta earthquake.

The officials sought help from the Marine Mammal Center to find a way to deal with sea lions. Ratner said that the final decision is to let the sea lions stay and coexist with humans. "The fact proves that this is really a good thing," he said. "This is just a proof of how we can truly work together and think about how we can share our coasts with marine mammals and other wildlife in a way that benefits all the parties involved."
