Will you be playing some music at work?

    Music is particularly popular in the medical profession, especially among surgeons（外科医生）. A recent survey shows that 90% of surgeons in the UK put music on the sound system in the theatre during operations. Plastic surgeons（整形外科医生）play the most music; it appears that ear, nose, and throat specialists the least.

    But it isn't only in surgeries(外科手术) where music is popular. In another recent survey, one-third of the 1,613 people said they listen to music while working. And 79% of them said that humming（哼歌）along improves their job satisfaction or productivity.

    Is listening to music at work a good idea? Yes, say the experts. Many surgeons say that music helps to create a “calm atmosphere”, and a third of them added that it avoids getting bored! Also, listening to music raises the levels of a brain chemical that can help people focus. Office workers say it improves job satisfaction. Several studies suggest that it's also good for hospital patients. Those listening to music through headphones during surgery require less anesthetic（麻醉剂）, up to 50% less in some cases, and recover more quickly afterwards. “Sure, music reduces anxiety before surgery,” says Zeev Kain, an anesthetist at Yale University.

    So, what type of music should we be listening to? Surgeons from the previous survey preferred rock, pop music and classical. And hip-hop is popular too. However, whatever the kind, it appears that self-selected music is the best choice. Pennsylvania State University research showed that when people chose their own music there was more stress reduction(下降). And other researchers found that when listening to self-selected music, surgeons did the maths faster and more accurately than when they were listening to music chosen for them.

    On a Sunday morning, I was driving down a road and saw something I couldn't believe. A little girl, less than two, was pushing her stroller (婴儿车) across the road. It was Sunday morning and traffic was not heavy.

    I stopped my car at once and ran toward her. This little girl knew enough to run from a stranger. I tried to catch her in order that I could get her out of the road. Suddenly her father came running down a hill across the road from where I had parked my car. He ran right to her and caught her up, saying “bad girl” to her. I picked up the stroller and gave it to him. The father grabbed（抓住） the stroller and walked toward where he came from without a word. I went back and sat in my car for a few minutes with my son. My hands were shaking and tears were about to run out of my eyes. “Do you feel cold, Mom?” asked my son. I just shook my head.

    After this happened, I thought about how thankful I am. Even though the father didn't say thank you, I feel that I did something good. Doing something for someone else is pleasing, even when it's only a matter of being in the right place at the right time. I didn't really “save” her, but I feel like it was important that I happened to be there. It is sad that I was the only one who stopped. It really made me a little disappointed that no one else stopped to help.

    Bad news sells. If it bleeds, it leads. No news is good news, and good news is no news. Those are the classic rules for the evening broadcasts and the morning papers. But now that information is being spread and monitored in different ways, researchers are discovering new rules. By tracking people's e-mails and online posts, scientists have found that good news can spread faster and farther than disasters and sob stories.

    "The 'if it bleeds' rule works for mass media," says Jonah Berger, a scholar at the University of Pennsylvania. They want your eyeballs and don't care how you're feeling. But when you share a story with your friends, you care a lot more how they react. You don't want them to think of you as a Debbie Downer."

    Researchers analyzing word-of-mouth communication—e-mails, Web posts and reviews, face-to-face conversations—found that it tended to be more positive than negative, but that didn't necessarily mean people preferred positive news. Was positive news shared more often simply because people experienced more good things than bad things? To test for that possibility, Dr. Berger looked at how people spread a particular set of news stories: thousands of articles on The New York Times' website. He and a Penn colleague analyzed the "most e-mailed" list for six months. One of his first findings was that articles in the science section were much more likely to make the list than non-science articles. He found that science amazed tines' readers and made them want to share this positive feeling with others.

    Readers also tended to share articles that were exciting or funny, or that inspired negative feelings like anger or anxiety, but not articles that left them merely sad. They needed to be aroused one way or the other, and they preferred good news to bad. The more positive an article, the more likely it was to be shared, as Dr. Berger explains in his new book, "Contagious: Why Things Catch on."

    Buddy or Friendship Benches (长椅)are needed because playgrounds can be lonely places sometimes. When a school places the bench, they teach a little lesson to the kids on how it is to be used. Then when a child sits on the bench, it sends out a message to others that basically says, " Hey, I'm alone right now and would welcome the company (陪伴) of others." Kids in the playground see this and from their training, they see there is a fellow student in need. They are encouraged to come over and sit on the bench and make a new friend.

    Benches like this have been around for a while now in many schools. But in Ireland, they are trying to do something different with them. This school in Cork in the south of Ireland is the 247th to get benches from a social organization called "Buddy Bench Ireland" that doesn't just provide schools with benches, but also runs special projects with trained child psychiatrists (精神病专家).They use the bench as an opportunity to start conversations about mental health. They talk about the importance of knowing and understanding your feelings and those of others.

    Judith Ashton, a co-founder of Buddy Bench Ireland said, "The children need to understand what the bench is about, what it represents —friendship, understanding, listening to each other and the most important thing is that it's important to express feelings."

    But do children really use the bench? It's a matter of great public concern. Sinead Mcgilloway from Maynooth University carried out a study and said, " We found that 40% of the children told us that they had actually used the benches at the time of the study. And over 90% said that they would talk to a child if that child was sitting on the bench. So, there's nothing to worry about.

    Children's mental health and safety at school is increasingly a concern in many countries. In Ireland, they're hoping these benches will not only tackle problems like school violence and school bullying (校园暴力和校园欺凌), but also give students the confidence to open up about their feelings.

The new garbage sorting regulation has taken effect in Shanghai starting July 1. Many citizens are still confused about the classification of the four different types of trash. Thankfully, authorities have released an official guideline to clarify the new rules.

The guideline, published by the Shanghai Greenery and Public Sanitation Bureau, provides a rather clear definition on the four kinds of waste: recyclable waste, hazardous (有害的) waste, household food waste and residual (剩余的) waste.

Hazardous waste, as the name suggests, includes assorted poisonous materials like used batteries, light bulbs, out-of-date medicines, paint and pesticides.

Household food waste, which is translated to "wet trash" in Chinese, refers to food leftovers, rotten food, pet food, fruit peels, remains of TCM herbs (中药) and flowers.

Paper, plastic, glass, metal and textiles (纺织品) are counted as recyclable waste.

The definition of residual waste is a little confusing. Anything that is not listed above belongs in this category.

As specific as the new guideline is, residents still have a hard time sorting trash correctly and are finding it challenging to memorize them all. For instance, both plastic bottles and bubble tea or coffee cups are plastic materials. However, the former falls to the category of recyclable waste and the latter belongs to residual waste. To save the hassle, some netizens have come up with their own ways to sort trash.

"We should do this from a pig's angle," commented one netizen. "Those edible (可食用的) for pigs are household food waste. Those even pigs don't want to eat are residual waste. If a pig consumes something and dies of it, then something must be hazardous waste. Those which can be sold and the money we gain can be used to purchase pigs are recyclable waste." The new regulation has gone into effect on July 1. Those who do not sort their trash properly will be fined RMB200.
