    (CNN) — A 12 -year-old girl who had a feeling that she might be quite clever has taken a test and proved she was absolutely right.

    Lydia Sebastian achieved the top score of 162 on Mensa's Cattell III B paper, showing she has a higher IQ than well-known geniuses Albert Einstein and Stephen Hawking. The comparison doesn't sit well with the British student, who's currently in Year 8 at a selective girl's grammar school in Essex, England.

    "I don't think I can be compared to such great intellectuals as Albert Einstein and Stephen Hawking. They've achieved so much. I don't think it's right," Lydia told CNN.

To explain Lydia's mark's level, the top adult score in the Cattell III B test, which mainly tests verbal(语言) reasoning, is 161. A top 2% score — which allows entry to Mensa, the club for those with high IQs — would be 148 or over. Lydia scored 162, placing her in the top 1% of the population.

    Lydia's not quite sure what she wants to do when she leaves school, although she's leaning toward something "based on Maths, because it's one of my favorite subjects." "All I'm going to do is work as hard as I can, and see where that gets me," she said.

    We Brits love the idea of a real Christmas tree but not so many of us like the realities of dragging (拖拽) a 7ft Norway Spruce through the house and leaving needles all over the place.

    If you count yourself among the reluctant group, then it may be time to go fake (假的) . After all, buying an artificial Christmas tree needn't mean accepting defeat. There's a huge range of choices and sizes, including pre-lit trees, which will save you the frustration of trying to string your own lights.

    Another big advantage of choosing an artificial Christmas tree is cost: artificial trees can last for decades, so they work out cheaper than paying for a real tree every year. Like now retailers (零售商) are offering great deals at the moment: at Tesco, there's 25 percent off artificial Christmas trees. Meanwhile, you can take advantage of the current 3 for 2 offer at Argos to fill your house with not one, not two, but three. You may perhaps partner up with friends who are also looking to invest.

    Of course, keep your tree for years and years and it will start to pay you back in terms of carbon footprint; however, a “real” one will always have to be transported, used and dealt with every year.

    Are there any downsides? Yes. You might think you're saving the planet, but a fake tree is actually not an environmentally friendly option. Most are made in factories in Asia, resulting in some serious air miles to reach the UK. They're made from metal and plastic, and many end their lives in landfill (垃圾填埋).

    Another problem with a fake tree is that they don't look very natural and of course you won't get that lovely pine smell either. You'll also need to find space for storage.

Internet time tied to teen depression(抑郁) symptoms

    Spending time online is normal behaviour for teenagers. But too much Internet use by teens —or too little, for that matter —might be related to depression, a new study finds.

    The findings, reported in the journal of Pediatrics, do not mean that the Internet is to blame. For one, teens in the study who spent no time online were also at increased risk of depression symptoms. Instead, the researchers say that both heavy Internet use, and non-use, could serve as signals that a teenager is having a hard time.

    For the study, Dr. Pierre-Andre Michaud and his colleagues at the University of Lausanne, Switzerland, surveyed 7,200 individuals aged 16 to 20 about their Internet use.

    Those who were online more than two hours per day were considered "heavy" Internet users, while those online anywhere from several times per week to two hours per day were considered "regular" users.

    The teenagers also answered a number of health-related questions, including some standard questions about "depressive tendencies" that gauge(判定) how often a person feels sad or hopeless. Compared with regular Internet users, the study found, kids who were heavy users or non-users were more likely to be depressed or very depressed.

    Among male teens, heavy users and non-users were both around one-third more likely to have a high depression score, compared to "regular" users. Among girls, heavy Internet users had an 86 percent greater chance of depression, while non-users had a 46 percent greater likelihood compared to regular users.

    That was with factors like family income and any chronic health problems taken into account.

    Since teenagers typically go online to contact with friends, the researchers speculate(推测) that those who are never online may be more socially isolated.

    JERUSALEM—Israel's Environmental Protection Ministry asked citizens Wednesday to avoid unnecessary physical activity and stay indoors, as a serious sandstorm struck the Middle East in a thick yellow haze (霾) for a second day with no hope to see things clearly.

    The ministry said heavy levels of dust and sand in the air were a threat to cities throughout the country. The ministry's website advised pregnant women, the elderly and those with heart and respiratory (呼吸的) conditions to stay indoors, and asked schools to keep children indoors.

    The emergency service Magen David Adom reported that it has treated more than 300 Israelis suffering from breathing problems, and that hospitals have more respiratory-related patients, including a large number of the elderly and those with asthma and related conditions.

    The domestic Israeli airlines Arkia and Israir continued to ground their flights to Eilat because of reduced visibility.

    The sandstorm has affected Egypt, Jordan, Iraq, Lebanon and Syria, where at least five deaths have been reported.

    "There has been nothing that came close to the magnitude of this sandstorm," said Daniel Rosenfeld, a professor with the Institute of Earth Sciences at the Hebrew University in Jerusalem.

    "While Israel has experienced a number of sandstorms in the past, they started from the Sinai Desert and the Sahara Desert to the south and were joined by winter windstorms that cleared the air," he said. In this case, the storm comes from Syria and Iraq to the north and east.

    Because the storm is hitting during the summer, at a time of both little wind and severe heat and humidity, forecasters expect the particles to remain in the air throughout the weekend and possibly into next week.

    "This is really puzzling," said Rosenfeld, adding that he and his colleague will conduct research into the origins of the unprecedented (前所未有的) storm. (326 words)

    We've all fantasized about it—after a rough day at work, stuck in traffic with commuters (上下班的人) we'd rather not have in our personal space, and bills to pay, plus the sound of the crying baby in the apartment next door. How nice would it be to go solo and live on an island of one, population: me?

    Well, this is the reality for 84 year old Elsie Eiler of Monowi, Nebraska. She is the sole resident of her hometown, which is the smallest recognized locality in the United States.

    Looking back at the 2000 census (人口普查), the town used to have another resident: Elsie's husband Rudy. Since he died in 2004, Elsie has lived in the town by herself. She considers herself to be the mayor, treasurer, and town librarian. Her main source of income is the bar that is frequented by truckers and other people passing through—the Monowi Tavern, which she founded with her late husband back in 1971 . She received a lot of public attention after it was discovered that she was the sole resident of Monowi, and in an interview she stated that many visitors from around the world have come to meet her in Monowi.

    When asked if she ever gets lonely, she said "I know I could always move closer to my children or stay with them whenever I want, but then I'd have to make all new friends again. Hopefully I will be able to stay here. It's where I want to be."
