We all know that listening to music can soothe emotional pain, but Taylor Swift, Jay-Z and Alicia Keys can also ease physical pain, according to a study of children and teenagers who had major surgery.

    The research was carried out because of a very personal experience. Sunitha Suresh was a college student when her grandmother had major surgery and was put in intensive care (重症监护). This meant her family couldn't always be with her. They decided to put her favorite music on an iPod so she could listen around the clock.

    It was very calming, Suresh says. “She knew that someone who loved her had left that music for her and she was in a familiar place.”

    Suresh could see that the music relaxed her grandmother and made her feel less anxious, but she wondered if she also felt less pain. That would make sense, because anxiety can make people more sensitive to pain. At the time Suresh was majoring in biomedical engineering with a minor (兼修) in music cognition (认知) at Northwestern University where her father, Santhanam Suresh, is a professor of pediatrics (儿科).

    So the father and daughter decided to do a study. And since Dr Suresh works with children, they decided to look at how music chosen by the children themselves might affect their tolerance for pain.

    It was a small study, involving 60 patients between 9 and 14 years old. All the patients were undergoing big operations that required them to stay in the hospital for at least a couple of days. Right after surgery, patients received narcotics (麻醉药) to control pain. The next day they were divided into three groups. One group heard 30 minutes of music of their choice, one heard 30 minutes of stories of their choice and one listened to 30 minutes of silence via noise canceling headphones.

    After a 30-minute session, the children who listened to music or books reduced their pain burden by 1 point on a 10-point scale. Sunitha Suresh says it's equal to taking an over-the-counter pain medication like Advil or Tylenol.

    The findings suggest that doctors may be able to use less pain medication for their pediatric patients. And that's a good thing, says Santhanam Suresh, as children are smaller and are more likely to suffer side effects. So the less pain medication, he says, the better.

    When I was trying to find a place where to spend my December holidays, I met by chance some cheap flights to Iceland. After checking just a few winter pictures of Iceland, I realized that the country, known as the land of fire and ice, during the cold months of the year could offer me experiences I had never had before.

    For sure you can't miss the chance to go to Iceland in winter if your traveling wish list includes at least one of the crazy experiences Iceland can offer. Iceland in the North

    Atlantic Ocean is a paradise ( 乐 园 ) for all those who want to see the northern lights, experience cold weather conditions and put themselves in geothermal ( 地 热 的 ) baths while the snow is falling on their head.

    The best way to move around Iceland is with a rental car. Distances are huge and public transport in winter is not really common out of the major towns. As we wanted to be even more convenient we decided to rent a small camper ( 野 营 车 ). Sleeping and cooking in a camper saved us a lot of driving, money and gave us the chance to be always in the right place at the right time.

    There were also no locals and in many cases no tourist facilities (设备). For us, as we slept in a camper, it was easier. But for tourists traveling by normal cars it is necessary to check the opening times of hotels and restaurants as many of them run just from June to September.

    It is amazing to experience how the weather is changing in Iceland. However, Icelanders prefer to stay inside their houses. They have even no time to complain about the weather in December. All they care about is Christmas. They love to decorate their houses, sing Christmas songs and eat typical Christmas food.

    ①About 43.5 million Americans are taking care of aging relatives and friends, sacrificing(牺牲) time, money and sometimes their careers and personal health. They are doing the work of professional caregivers, who spend years training for the job. As baby boomers age, the demand for unpaid caregivers is rising. Meanwhile, the number of them is dropping rapidly thanks to smaller family sizes, higher divorce rates and increasingly demanding jobs. This November, actor Rob Lowe offered to tell his story and send some encouragement to the millions struggling to care for a loved one.

    ②I had my first experience with unpaid care giving fairly early. My father, Charles, was diagnosed(诊断)with lymphoma at age 50. I was 26. Luckily, he was financially successful and had a loving wife, my stepmother. It was challenging, but she was there from taking care of my father.

    ③In my late 30s, my mother, Barbara Hepler, was diagnosed with stage 4 breast cancer. That was when I was introduced to the front lines of what so many millions are experiencing. She did not have a husband or a significant other, so it fell to me and my two brothers to handle everything from her initial diagnosis to doctor shopping, treatment options, driving her to appointments and, finally, the end of life-which was profoundly difficult, obviously.

    ④At the time, I was starring in and producing a network television show, The Lyon's Den. It was fighting for its ratings life. If I took time off, the show would be canceled, I was responsible for 150 crew members, so I had to find a way to do both.

⑤Besides, there is the negotiation of medical coverage, which requires phone calls, weeding through paperwork and talking to insurance companies and doctors. I remember thinking, Jesus Christ, if I were sick and had to do this on my own? I don't think I could get out of bed in the morning.

    ⑥The people we are talking about-the friends and family members who are out there doing important work-are unpaid. Watching a loved one go through an illness, possibly ending in death, is stressful and depressing. Add economic and scheduling burdens, and the load for caregivers is heavy. To them I say, "Don't forget about yourself. When you get on an airplane, the crew says, Secure your own mask first before helping others.” Why? Because without you taking care of yourself, you can't take care of anybody else. That's why I've partnered with EMD Serono andEmbracingCarers.com, where you'll find invaluable information regarding everything you'll be, or are, going through.

    "Mum, what does it mean when someone tells you that they have a skeleton（骨骼）in the closet（衣橱）?" Jessica asked. "A skeleton in the closet?" her mother paused thoughtfully, "Well, it's something that you would rather not have anyone else know about. For example, if in the past, someone in Dad's family had been arrested for stealing a horse. It would be a skeleton in his family's closet'. He really wouldn't want any neighbor to know about it."

    "Why pick on my family?" Jessica's father said with anger. "Your family history isn't so good, you know. Wasn't your great-great-grandfather a prisoner who was transported to Australia for his crimes?" "Yes, but people these days say that you are not a real Australian unless your ancestors arrived as prisoners." Gosh, sorry I asked. I think I understand now," Jessica cut in before things grew worse.

    After dinner, the house was very quite. Jessica's parents were still quite angry with each other. Her mother was ironing clothes and every now and then she glared at her husband, who hid behind his newspaper pretending to read. When she finished, she gathered the freshly pressed clothes in her arms and walked to Jessica's closet. Just as she opened the door and reached in to hang a skirt, a bony arm stuck out from the dark depths and a bundle of white bones fell to the floor, Jessica's mother sank into a faint（晕倒）, walking only when Jessica put a cold, wet cloth on her forehead. She looked up to see the worried faces of her husband and daughter.

    "What happened? Where am I?" she asked. "You just destroyed the school's skeleton, Mum," explained Jessica, "I brought it home to help me with my health project. I meant to tell you, but it seemed that as soon as I mentioned skeletons and closets, it caused a problem between you and Dad." Jessica looked in amazement as her parents began to laugh madly. "They are both crazy," she thought.

    Research shows that some orchestral(管弦乐的) instruments are in a danger of dying out.YouGov research, asked by the Royal Philharmonic Orchestra (RPO) to find the most popular instruments among schoolchildren, has revealed the increasing popularity of the ukulele(尤克里里琴), with one in eight expressing a desire to learn, making it the highest ranked instrument behind the typical rock-band grouping of the guitar, piano, keyboards, drums and bass guitar.

    But younger generations' interest in"more complex instruments"is decreasing, with the three least popular being the French horn, the double bass and the trombone.

    James Williams, managing director of the RPO, believed the changes reflect the increasing pressure schools are under to provide music education, and went on to say that more needs to be done to interest secondary school students in the wider range of instruments. His concern was for the composition(构成) of future orchestras if the trend towards instruments like rock-band grouping were allowed to continue. But there may be yet another death, one that few would be quick to sorrow over：the recorder(竖笛).

    Cheap, convenient, easy to learn, and suitable for individual and group performances, the recorder was once the go-to instrument for children's early musical education.But in many schools it has been replaced by the ukulele, which, for teachers, offers many of the same benefits with none of the lasting damage to hearing. Plus, from a student's viewpoint: you can play Metallica on one.

    Not all hope is lost for the cream-colored, 10-pound Yamaha recorder with a long history, however. About 13% of girls and 4% boys surveyed by YouGov said they wanted to learn the recorder.Surprisingly high! Unlikely as it may be, these children's interest in the recorder must be encouraged.

Restless in their seat, glancing around and never looking you in the eye. We think we know when someone is lying, but do we really?

A study showed that people's ability to tell if someone is lying is little better than 50%. Interestingly, another research suggests that we are actually quite good at unconsciously (无意识地) spotting liars, but our conscious thoughts overrule this. Scientist R. Edward points out that training in recognising liars doesn't always help, saying "quick, inadequate training sessions lead people to over-analyse and to do worse than if they go with their gut reactions (本能)". 

One reason for this may be "truth bias". Experts have suggested that we are usually biased to believe that people are telling us the truth. Another reason that might make us bad at identifying liars is that there are many myths around body language and lying. Many of us believe that liars are unlikely to look us in the eye or will be uneasy in their seat. However, this isn't necessarily the case. It may be that not looking away, or sitting more still than usual, are actually the giveaways that someone is lying. 

To see how someone's behaviour really changes as they lie, many experts recommend observing people talking about things known to be true. This allows us to establish a baseline of their normal behaviours while speaking. Any differences to this baseline behaviour could show that someone is lying. This is why it's much harder to lie to people who know us well.

As liars may be working hard to conceal their behaviours, some psychologists have suggested increasing the effort needed for this by asking them to tell their story again backwards. When facing this increased cognitive (认知的) load, any behavioural tell-tale signs are magnified (放大).

It can be hard to spot liars. We are likely to trust people, and behaviours can be hidden, but if we know someone well, and if someone is working too hard to stick to their story, it's possible to see through people who are not telling the truth.
