    It has long been thought that elephants rely on their large ears and bathing in rivers to stay cool in hot climates. New research, however, has showed that the world's largest land animals have a secret trick of controlling their body temperatures.

    Scientists have long been puzzled by temperature regulation(调节)in elephants. Generally, animals with large bodies tend to hold more heat because, compared to their size, they have a small surface area for heat to escape from. Elephants, with their heavy­weight frames, would appear to be at a disadvantage in the heat of their African and Asian habitats, especially because they have thick fur to protect them from bushes and trees.

    Scientists thought that these creatures, which weigh up to 13 tons when fully­grown, grow large ears to help them stay cool. The skin on the ears is thinner, so blood which flows into them cools down more easily. But findings by researchers at two universities in Vienna have showed that elephants are also able to cool down by increasing the blood flow to skin patches(斑) in other parts of their bodies.

    The researchers studied six African elephants at Vienna Zoo as they moved between outdoor and indoor environments to see how the temperature on their skin surface would change. They found up to 15 “hot spots” all over an elephant's body surface, in addition to large patches on the ears. The study shows how these patches expand as the air temperature increases and more blood flows nearer to the skin surface. Other experiments show that elephants in the wild use the same “windows” to control their body temperature.

    Elephants have two additional ways to stay cool: flapping(拍打)the ears and bathing. Together with these tricks, the skin hot spots allow the animals to keep their body temperature always at about 36 degrees—one degree less than humans'.

(1)、What can we know about the elephants?
A、They have thick fur to protect them. B、They live in cool areas in Africa and Asia. C、They can weigh up to 3 tons when fully­grown. D、They are afraid of water and rivers.
(2)、The function of the thinner skin on elephants' ears is to________.
A、control their body temperature B、help hold more heat C、drive away insects D、keep sensitive hearing
(3)、The new research________.
A、studied six Asian elephants B、studied elephants in a zoo and in the wild C、aimed to discover the elephants' disadvantages D、proved that scientists' earlier beliefs were totally true

    'Kangaroo mothering' helps boost a child's health and intelligence

    “Kangaroo mothering”, the practice of continuous skin-to-skin contact with a newborn baby, results in healthier, more intelligent and successful children, a new study finds.

    A 20-year follow-up research found that those brought up in the kangaroo method scored higher in IQ tests and earned 53% more. They were also found to be less likely to have behavior problems than babies in a control group.

    Followers of the method nest their kids in a “kangaroo” position on their chest as soon as possible after birth. Both mother and baby are supposed to go home as quickly as possible.

    The technique is often used in cases of premature birth (早产). In such cases, the trained mother acts as the child's main source of stimulation (刺激) and food, in the form of breast feeding. Between 1993 and 1996, a group of more than 700 prematurely born babies in Columbia were, on the basis of random selection, placed either away from mother or were raised using the kangaroo method. Two decades later, a follow-up survey funded by the Canadian Government has shown that those who went through the latter method benefited by comparison.

    Published in the journal Paediatrics, the research shows that kangaroo mothering offered significant protection against early death, with a 3.5% death rate compared to a 7.7% rate in the control group. IQ test also showed a small but significant advantage of 3.5% compared to other infants

    Lead researcher Dr Nathalie Charpak, of the Kangaroo Foundation in Bogota, said the method has “significant, long-lasting social and behavioral protective effects”. “We firmly believe that this is a powerful, efficient, scientifically based healthcare intervention that can be used in all settings, from those with very restricted to unrestricted access to healthcare.”

    The study also found that, compared with babies in the control group, those raised in the kangaroo method went on to develop bigger brains, with significantly larger volumes of gray matter.

    Next time you hear a funny joke you'd better not laugh too hard. According to a paper published by the British Medical Journal, laughter isn't always the best medicine. Sometimes it can even be harmful. Professor Robin Ferner from the University of Birmingham, one of the authors of the study, found that bad things could happen to people who laughed too much. He says, "We found people with heartbeat problems which had stopped their hearts, we found people who had fainted(昏倒), and we found people who'd dislocated their jaws or burst their lungs."

    It seems that laughing can be no laughing matter. But it's not all doom and gloom. Professor Ferner says there are benefits to laughing when you want to lose weight, for example. Yes, that's right: laugh and be slimmer! Professor Ferner explains that: "You use energy when you laugh, you move your diaphragm(横隔膜), you expand your lungs, and both those things can be helpful."

    According to the research, laughing for a quarter of an hour can burn 40 calories, and if you laughed all day you'd use about 2, 000 calories, which is what most people consume in a day. But don't do that or you might end up with a painful jaw. Ouch! Or you might find people looking at you in a funny way.

    But I don't want to finish this article leaving you feeling desperate. Laughter comes naturally for most of us. Babies begin to laugh at around 3-6 months. So give in to your sense of humour and keep smiling. Life is short anyway.

    Very few people enjoy going to the dentist, especially for a filling. Often fillings need to be replaced during the patients' lifetime. But is filling the cavity (蛀洞)with a foreign material really the best treatment? What if the tooth could repair itself with its own material–dentine(齿质)? Researchers at King's College London have found a process that may replace the traditional method.

    Paul Sharpe of King's College says a new treatment for cavities is simpler. It uses a drug that causes the tooth to fill in the hole naturally with dentine. "It involves putting a drug in the hole. It excites a natural process, which starts to occur anyway following the damage, so you can actually get the big hole repaired and the repair is a production of the natural material, the dentine."

    Usually a new drug requires repeated testing before it is approved for treatment. However, this drug that produces the re-growth in teeth has already been approved. It is a drug used to treat Alzheimer's disease and other disorders of the nervous system. Researchers explain that they use only a small amount and they use it locally. Usually that means the medicine is put directly on the affected area. It does not travel through the patient's blood.

    Nigel Carter heads Britain's Oral Health Foundation. He describes the new treatment as an exciting possibility for dental care. But Carter also has a warning. "Actually re-growing the tooth that has been lost with a cavity would be really a huge step forward. But, it's also important that we remember that we shouldn't be getting the cavity in the first place. We're talking about a totally preventable disease."

    One evening I was going back from a supermarket. As I was approaching my car, I noticed that some person came and stood beside me. He was the one that could be considered as a bum. It seemed that he had no car, no home and no job. I thought that he would ask me for money, but he did not do that, he only said: "Your car is very nice".

    After several moments of silence, I replied: "Thanks", and then the inner voice told me, "Ask him if he needs help". After a short hesitation I asked him if he needed any help. His response was astonishing. I will never forget those simple three words that I heard from him: —"Don't we all?"

    It was a true discovery to me. I needed help. Although I had money and a place to sleep, I recognized that I needed help too. Then I opened my wallet and gave him enough money to get a meal and some shelter for a day.

    Suddenly I understood that no matter how much money we have, we all need help. On the other hand, no matter how poor you are and how many material problems you have, you still might offer your help to others and you still might be giving. Even it's just a nice word, you can give that and it can be priceless to other persons.

    Maybe that man was just a homeless stranger, but to me he was more than that. Maybe he was sent by the Highest Loving Power personally to me to open my eyes and to show me that there is one thing, among all other values, which is very important and irreplaceable for each and every person. Actually, it is a true gift and it is called Giving.
