When milk arrived on the doorstep

    When I was a boy growing up in New Jersey in the 1960s, we had a milkman delivering milk to our doorstep. His name was Mr. Basille. He wore a white cap and drove a white truck. As a 5-year-old boy, I couldn't take my eyes off the coin changer fixed to his belt. He noticed this one day during a delivery and gave me a quarter out of his coin changer.

    Of course, he delivered more than milk. There was cheese, eggs and so on. If we needed to change our order, my mother would pen a note-“Please add a bottle of buttermilk next delivery”-and place it in the box along with the empty bottles. And then, the buttermilk would magically appear.

    All of this was about more than convenience. There existed a close relationship between families and their milkmen. Mr. Basille even had a key to our house, for those times when it was so cold outside that we put the box indoors, so that the milk wouldn't freeze. And I remember Mr. Basille from time to time taking a break at our kitchen table, having a cup of tea and telling stories about his delivery.

    There is sadly no home milk delivery today. Big companies allowed the production of cheaper milk, thus making it difficult for milkmen to compete. Besides, milk is for sale everywhere, and it may just not have been practical to have a delivery service.

    Recently, an old milk box in the countryside I saw brought back my childhood memories. I took it home and planted it on the back porch （门廊）. Every so often my son's friends will ask what it is. So I start telling stories of my boyhood, and of the milkman who brought us friendship along with his milk.

    Every day, Americans throw away 500 million plastic straws, enough to circle the Earth twice. They are almost never recycled, and simply contribute to the great problem of plastic pollution; eight million tons of plastic is dumped into the oceans every year.

    Plastic straws are now the target of a growing movement to reduce their use. Possibly the first of such campaigns, Be Straw Free was started in 2011 by Milo Cress, who was only nine years old at the lime.

"I noticed that whenever I ordered a drink at a restaurant, it would usually come with a straw in it, and I don' I usually need a straw," he said. "This seemed like a huge waste. Straws are made of oil, a precious and finite resource. Is making single - use plastic straws, which will be used for a matter of minutes before being tossed away, really what we want to do with this resource?"

    Cress started asking restaurants in Burlington, Vermont, where he lived at the time, to stop providing straws automatically to customer and make them optional instead. Many agreed and his request made ripples (涟漪) nationwide. The restaurants that make the switch report a reduction in the number of straws they use between 50 and 80%.

    The anti - straw sentiment has crossed borders into the UK, where straws have been included in a government plan to ban ail plastic waste by 2042.

Last year large pub chain Wetherspoons announced that it would replace plastic straws with paper alternatives across 900 outlets. After the announcement, many smaller chains and pubs across the country followed suit. According to Wetherspoons CEO John Hutson, the move will save 70 million plastic straws a year and the reaction from patrons has been "very positive".

Offering alternatives or making plastic straws optional, rather than banning them completely, is a common trait among these campaigns. "There are many other viable alternatives to single - use plastic drinking straws that are less harmful to the environment, wildlife and humans," said Jackie Nunez, founder of The Last Plastic Straw.

    While your pet fish may appear to be unaware of your presence, chances are that it knows you extremely well and can probably even identify you from a crowd of human faces!

    To test if this was accurate, some scientists decided to study archerfish（喷水鱼）. These animals don't have a sophisticated（复杂的）brain that is necessary to recognize the slight differences between human facial features.

    They began by presenting four archerfish with images of two human faces. Initially, the fish spit at both. However, they soon learned spitting water at the one selected by the researchers earned them a food treat. After that, they focused primarily on that image. The researchers then took the experiment one step further by introducing 44 other human faces to the mix.

    To the researcher's astonishment, the trained archerfish were able to recall the learned image almost 81% of the time. And this accuracy improved to 86% when the researchers made the identification even harder, by replacing the colored photos with a set of black and white images and hiding the shape of the head.

    The results of the study suggest that though having tiny brains, archerfish may have developed high visual discrimination abilities. While it is contrary to the previous theory that a sophisticated brain is necessary to recognize human faces, the researchers believe they do not recognize faces by recalling complex facial information like gender and identity, but more likely by discriminating between detailed  patterns. Even so, the fact that these archerfish could “remember” those faces demonstrates that they have an impressive memory for details that lasts much longer than the originally-thought 3 seconds!

    This is not the first time researchers have realized how “smart” fish are. Previous studies have shown that fish can recognize those fish they have “socialized” with previously, and even recall complex three-dimensional maps of their surroundings.

Dogs are man's best friends—they are very good for children's health. Researchers found that family pets helped to protect babies against breathing problems and infections (感染).

    A team from Kuopio University Hospital in Finland studied 397 babies born at their hospital between September 2012 and May 2015 for their first year. They found that babies who lived with a dog or a cat spent fewer weeks with ear infections, coughs or runny noses. They were also less likely to need antibiotics (抗生素) than babies in homes without a pet.

    Study author, Dr. Eija Bergroth, said dogs brought dirt and bacteria (细菌) into the home, which helped children's immune system (免疫系统) to be strong. This improved their defenses against bacteria.

    As part of the study, parents filled out weekly diaries starting when the children were nine weeks old, recording information on babies' health as well as their contact with cats and dogs. They recorded if they had fever, ear infections, coughs or running noses. They also put down whether they needed antibiotics.

    Based on those diaries, the researchers found that about a third of the children spent most of their first year with a pet dog and 24 percent in a home with a cat. And children with no dog contact at home were healthy for 65 percent of the time, compared to between 72 and 76 percent for those who did have a pet.

    The researchers also found that contact with dogs, more than cats, was tied to fewer weeks of sickness for babies.

    However, the researchers said they couldn't rule out the possibility that people who own dogs are less likely to get sick for another reason, not due to any protection offered by pets.

    Your colleague's sharp comment keeps replaying in your mind. Two of your students are trapped in a "he said/she said" battle. When you reflect on your emotional reactions, you sometimes get caught up in cycles of negative feelings, which can make you feel even worse. If so, the answer may lie in a skill called "self-distancing", the ability to take a step back and view yourself more objectively. According to a research, when people adopt self-distancing while discussing a difficult event, they make better sense of their reactions, experience less emotional suffering, and display fewer signs of stress.

    But what might self-distancing look like in action? Consider a typical "he said/she said" student conflict where they are each focusing on their own feelings. One is thinking, "I can't believe he did that to me." And another insists, "She really hurt my feelings." However, if you ask them to take the self-distancing, they might step outside of themselves and ask broader questions: "Why was he so hurt in this situation?" or "How did her anger affect him?"

    Although this approach may sound too simple to be effective, studies indicate that a change in point of view can have a powerful effect on the way people think, feel, and behave. Here are several different techniques you can try.

    First, consider how a thoughtful friend might respond after quietly observing their situation. Besides, avoid using the pronoun "I". Focus on using third-person pronouns, he, she, they, and they were able to see the stressful event as challenging rather than threatening. Finally, ask yourself, "How would I feel about this one week from now or ten years from now?" This form of mental time travel may be effective because our attention is directed away from our immediate, concrete circumstances.
