The days when a cellphone was used for nothing beyond calling and texting are gone. Today, we turn smart phones into magical machines with apps that transform them into musical instruments or business machines or video players. But it turns out that we are only searching the surface. Who knew that smart phones would make pretty good satellites?{#blank#}1{#/blank#}

Smart phones forecast the weather

      Networking expert Open Signal has discovered something interesting: the sensors in Android phones designed to measure battery  temperature, light, pressure and 80 on can be used to generate surprisingly accurate weather reports. {#blank#}2{#/blank#}

Smart phones save the rainforests

       Detecting illegal logging(盗伐) may sound like a novel app, {#blank#}3{#/blank#}: in Indonesia, the non-profit organization Rainforest Connection' wants to use donated Android phones to detect illegal logging. As Newscientist reports, “The phonesare equipped with solar panels specifically designed to take advantage of the brief periods when light reaches the forest floor. Their microphones stay on at all time, and the software listens for the sound of a chainsaw(链锯).”

        Researchers at the university of Illinois have developed an iPhones app that turns the phone into a fully featured mobile medical lab that uses the phone's camera to detect proteins, bacteria, viruses and other organisms.

Smart phones drive cars

    Mosquitoes have an extraordinary ability to find humans far away and fly straight to their skin. Mosquitoes can do more than cause an itchy (发痒的）wound. Some mosquitoes spread several serious diseases, including Dengue, yellow fever and malaria.

    Over one million people worldwide die from these diseases each year. New research now shows how mosquitoes choose who to bite.

    Mosquitoes need blood to survive. They are attracted to human skin and breath. They smell the carbon dioxide gas, which all mammals breathe out. This gas is the main way for mosquitoes to know that a warm-blooded creature is nearby.

    But mosquitoes also use their eyes and sense of touch. Michael Dickinson is a professor at the California Institute of Technology. His research shows how these small insects, with even smaller brains, use three senses to find a blood meal.

    Michael Dickinson's team used plumes—a material that rises into the air of carbon dioxide gas into a wind tunnel (隧道). They then used cameras to record the mosquitoes. The insects followed the plume.

    Then, the scientists placed dark objects on the lighter colored floor and walls of the tunnel. Mr. Dickinson said, at first, the mosquitoes showed no interest in the objects at all. “What was quite surprising is that the mosquitoes fly back and forth for hours. These are hungry females and they completely ignore the objects on the floor and wall of the tunnel. But the moment they get a hit of CO₂, they change their behavior quite obviously and now would become attracted to these little visual blobs (斑点).”

    This suggested to the researchers that a mosquito's sense of smell is more important in the search for food. Once mosquitoes catch a smell of a human or animal, they also follow visual signals.

    All over the world, children in hospital are being treated with a new kind of medicine：Laughter. Lucy is 23 and works for Theodora Children's Trust. She is one of many clown (小丑) doctors who bring a smile to the faces of sick children.

    “I'm a Theodora clown doctor. I call myself Dr Looloo. I spend two days a week in children's hospitals, making funny faces, telling jokes, and doing magic tricks. As I walk into the wards(病房) I blow bubbles, shake hands with the kids, and make up nonsense songs for those children well enough to sing. I take special balloons to make 'balloon animals' and tell funny stories about them.

    I'm naturally a very cheerful person. I've always been a clown. In fact my father's a clown and I started working with him when I was eight years old. I knew it was just the job for me and I became a clown doctor because I think it's a great way to cheer up sick, frightened children in hospital.

    Being a clown in hospital is very tiring both physically and emotionally. We have to learn not to show our feelings, otherwise we'd be useless. Clown doctors are sensitive but this is not a side most people see. To the children we're happy all the time. I'm still learning to allow myself to feel sad occasionally. There working with a very sick little girl from Bosnia who speaks no English, so our only common language is laughter.

    At weekends I participate in events to raise money for Theodora Children's Trust. It's a charity, so we are paid with the money people give. Being a clown doctor makes the worries of everyday life seem small. All in all I feel honoured to do this job.”

    Overheated property markets in major cities have started to cool down after authorities took measures against speculative buying and a potential home market bubble. However, a long-term effort is needed to make the market stable and sustainable, analysts said.

    Last month, new home prices dropped in seven cities, compared with six in September, according to the National Bureau of Statistics, which monitors housing prices in 70 cities nationwide. In Shenzhen, where housing prices rocketed by more than 30 percent in the past several months, prices declined by 0.5 percent in October.

    “After first-tier cities and some key second-tier cities launched cooling measures, home prices have obviously become stable,”Liu Juanwei, NBS senior statistician, wrote in a note posted on the NBS website.

    Beijing, Tianjin, Shanghai, Xiamen and Zhengzhou began to see home prices switching from rising to dropping in the second half of October, with average prices down by between 0.1 percent and 0.4 percent compared with the first half of the month, he noted.

    Housing authorities in more than 20 cities have launched various measures against speculative buying to curb rapid home price growth, including setting stricter requirements for qualified buyers and limits on buying second and third homes.

    Yan Yuejin, an analyst with property research agency E-House China R&D Institute, said the residential property market is “digesting these policies and measures gradually, and it is likely for the market to have rational and stable prices in the near future.”

    Ma Junwei, an analyst with Deyi Realty in Shanghai, said it will require a long-term effort by regulators and local authorities to battle speculative buying while keeping supplies stable for buyers with solid demand, including those who plan to buy their first home or upgrade their housing.

    In Shanghai, real estate agents said that they have noticed that homebuyers have become more rational. “Buyers are starting to take their time and study their options. They will compare prices, designs and locations and bargain with sales representatives,”said Luo Dingjun, sales manager at Jinyu Property Marketing.“This was not the case two months ago, when they rushed to buy for fear that if they hesitated, prices would grow too fast and they would no longer be able to afford. ”

    Putting a dinosaur skeleton(骨架)together is not easy. The skeletons are usually very incomplete. Many dinosaur fossils(化石) are discovered badly damaged. Bones are often found crashed (压碎) or bent by the great weight of the dirt and rock above. Sometimes parts from different creatures are mixed together. This just adds to the confusion.

    Unfortunately, some scientists have not been careful enough in their descriptions of dinosaurs. They have told grand stories of how dinosaurs looked and behaved. All of these descriptions are based on guesswork – the imaginations of people who have never seen a living dinosaur. Some scientists have made complete pictures of dinosaurs based on just a single bone or tooth or leg. Such pictures are based on many guesses and very little facts. The scientists' ideas often turn out to be wrong when more facts are discovered.

    Dinosaur fossils are not found with labels attached showing what the animals looked like. That is why no pictures of dinosaurs are exactly right. Every dinosaur painting is sure to contain at least some wrong information. No artist in the twentieth century ever saw the living, breathing animals -- complete with skin, flesh, and color.

    For instance, imagine never having seen or heard of a peacock. One day you find the jumbled bones of it buffed in the ground. You try to put the bones together to form a skeleton. And then you try to draw a picture of what the animal looked like when it Was alive. But bones cannot tell the whole story. Even if you are a very good artist, it would be a miracle if you drew a tree picture of a peacock just from the bones and your imagination.
