How to Care for Your Ears?

        Ears not only let us hear, but they alsoplay a role in maintaining our balance, which is vital to our ability to function in daily life. Yet, we ignore them. We can't even see our ears, exceptin a mirror. We take for granted what they do for us day in and day out－untilwe notice something's wrong, such as when an earache strikes or when we starthaving to ask people to repeat what they say.{#blank#}1{#/blank#}

◆ Clean your ear with a washcloth－coveredfinger only.

      Never put anything inside your earcanal, including cotton swabs (药签).{#blank#}2{#/blank#}．

◆ Leave earwax(耳垢)alone.

      Wax is your ear's way of eliminating(消除)anything foreign that gets into the ear canal.{#blank#}3{#/blank#}If you find you have too much earwax,use a few drops of earwax remover(去除剂) in the canal. After a few minutes,wash the ear with warm water.

◆ Avoid noisy places.

      Rock concerts and construction sites are just a few places that frequently have noise levels that can damage hearing.Any place where you have to shout to be heard should be avoided.

      Be careful not to play MP3 too loud, especiallyif using earphone.

◆Be careful with illness andmedications.

      Respiratory (呼吸的) illnesses should be treated to avoid their spread to the ears. Certainmedications can damage hearing, so follow the directions carefully beforetaking them.

      See your doctor if you suffer fromsudden hearing loss or hear noises in your head.

    When people reunite with their loved ones, it's usually all extremely happy moment. But what is their most common response to seeing them again? It may seem strange，but most of the time they break down in tears.

    Now a group of psychologists from Yale University say they have found the reason why, and that crying tears of joy may well be the body's way of keeping emotional balance. “They seem to take place when people are overtaken by strong positive emotions, and people who do this seem to recover better from those strong emotions,” Oriana Aragon, the lead researcher said.

    Aragon and her fellow psychologists looked at hundreds of participants' emotional responses to different things, including happy reunions and cute babies. Many participants said they would react in a negative or aggressive way to the positive things —— to cry at happy moments and want to pinch(捏)a cute baby's face or even tell them “I want to eat you up!” But then researchers found that these people were able to calm down from strong emotions more quickly.

    There are many other examples of times when people respond to a positive experience with a negative emotional reaction. At an exciting concert, fans scream at their idols(偶像). People who have just had a big lottery win are often in floods of tears. “These findings advance our understanding of how people express and control their emotions, which is importantly related to mental and physical health, the quality of relationships with others, and even how well people work together.” said Aragon．

    More and more people like bicycling and it is no surprise. It's fun, healthy and good for the environment. Maybe that's why there are 1.4 billion bicycles and only 400 million cars on roads worldwide today. Bikes can take you almost anywhere, and there is no oil cost!

    If you get on a bicycle and ride it, you may discover something new all around you. Stopping and getting off a bike is easier than stopping and getting out of your cars. You can bike to work and benefit from the enjoyable exercise without polluting the environment. You don't even have to ride all the way.

    Folding bikes work well for people who ride the train. Just fold the bike and take it with you. You can do the same on an airplane. A folding bike can be packed in a suitcase. You can also take a common bike with you when you fly. But be sure to look for information by getting on airline websites. Not all airlines are bicycle friendly to travellers.

    Here are some of Health Benefits of Bicycling：

    Bicycling helps to prevent heart diseases.

    Bicycling helps to control your weight.

    A 15­minute bike ride to and from work three times a week burns off five kilos of fat in a year.

    Bicycling can improve your mood.

    Exercise like bicycling has been shown to make people feel better, more relaxed and self-confident.

    Bicycling is healthier than driving.

    Babies teach their older brothers and sisters empathy (移情), according to a new research. Empathy means understanding and entering others' feelings. Until now, younger kids have generally been regarded to learn plenty from their older brothers or sisters but don't give back much. But this study, published in Child Development, confirms that younger siblings (兄弟姐妹) ensure their big brothers and sisters don't grow into disgusting people—no easy task.

    “Although it's assumed that older siblings and parents are the primary socializing influences on younger siblings' development but not vice versa, we found that both younger and older siblings positively contributed to each other's empathy over time,” study co-author Marc Jambon said in a statement. Prior sibling studies have focused on the influence of older brothers and sisters, probably because their impact is most obvious. As one review of literature notes, studies have shown that older siblings influence everything from their younger siblings' motor development to their risk of smoking later in life. And although separated studies have tried to pin down effects that younger siblings have on their older siblings, the influence of baby brothers and sisters remains unclear.

    For this new study, Jambon and his colleagues recruited (招募) a diverse group of 452 Canadian sibling pairs between the ages of 18 months and four years. At the start of the study, individual researchers assessed children's baseline empathy levels by visiting the kids at home and then pretending to hurt themselves or break a valuable item. Eighteen months later, they found small but significant increases in empathy.

    One unexpected exception—older sisters did not appear to experience increased empathy after 18 months living with their little brothers, specifically. The researchers aren't sure why this exception appeared, and they recommend that future studies dive into more complex phenomena.

    Moving flight times from night to day could reduce air travel's contributions to global warming, a new study suggests. Scheduling more (lay time flights may reduce the influence of contrails ——the visible lines of white steam that many planes leave behind them in the sky.

    The role of contrails in climate change is still being studied, but some scientists believe they contribute to the greenhouse effect by trapping heat in the atmosphere.

    Nicola Stuber, first author of the study, suggests that contrails' overall impact on climate change is almost as big as that of aircraft^? s carbon dioxide emissions (排放)over a hundred-year period. Aircraft are believed to be responsible for 2-3% of human carbon dioxide emissions. Like other high, thin clouds, contrails reflect sunlight back into space and cool the planet. However, they also trap energy in the atmosphere and increase the warming effect.

    Stuber and other scientists believe that the effect of the contrails is big. "On average, the green-house effect controls the effects of contrails, said Stuber, a meteorologist at England's University of Reading." The warming effect is far greater for contrails left by night flights," Stuber added. "The cooling effect only happens (luring the day when the sun is up. During the night the greenhouse warming is no longer balanced and that is why the contribution of night-flight is so large."

    Most commercial airline traffic occurs during daylight hours. For example, only one in four United Kingdom flights is a night flight, but those flights create some 60% of the warming created by contrails, the study reports.

 Chongqing heat sparks highest health alert
