I arrived at my mother's home for our Monday family dinner. The smells of food flew over from the kitchen. Mother was pulling out quilt (被子) after quilt from the boxes, proudly showing me their beauties. She was preparing for a quilt show at the Elmhurst Church. When we began to fold and put them back into the boxes, I noticed something at the bottom of one box. I pulled it out. “What is this?” I asked.

    “Oh?” Mom said, “That's Mama's quilt.”

    I spread the quilt. It looked as if a group of school children had pieced it together; irregular designs, childish pictures, a crooked line on the right.

    “Grandmother made this?” I said, surprised. My grandmother was a master at making quilts. This certainly didn't look like any of the quilts she had made.

    “Yes, right before she died. I brought it home with me last year and made some changes, she said. “I'm still working on it. See, this is what I've done so far.”

    I looked at it more closely. She had made straight a crooked line. At the center of the quilt, she had stitched (缝) a piece of cloth with these words: “My mother made many quilts. She didn't get all lines straight. But I think this is beautiful. I want to see it finished. Her last quilt.”

    “Oh, this is so nice, Mom,” I said. It occurred to me that by completing my grandmother's quilt, my mother was honoring her own mother. I realized, too, that I held in my hands a family treasure. It started with the loving hands of one woman, and continued with the loving hands of another.

    How do the world's only flying mammals communicate? Researchers have observed young bats adopting new “dialects” simply by hearing them repeatedly, making them one of the few animals known to have a capacity for vocal (声音的) learning. “These bats may help us clarify the evolution of speech acquisition (习得) skills,” says Yosef Prat, a PhD at Tel Aviv University (TAU).

    For one year, researchers raised 14 Egyptian fruit bat pups with their mothers in controlled area, exposing each young bat to two different vocalizations: the natural call of its mother and a separate recording that varied in pitch (音高) or frequency. They found that the pups in each group developed a dialect like the recording. “The general assumption in this field is that most animals develop their born vocalizations regardless of what they hear, and that human vocal learning abilities have developed during evolution,” says Mr Prat. “The finding that bats learn the common dialect in their rest place was unusual.”

    Scientists know little about the origin of spoken language, which is believed to have appeared in humans within the past 500,000 years. Dozens of theories attempt to explain the complexity of this skill, but none have done so conclusively.

    “Studying vocal communication and vocal learning in animal models is a very useful way to approach the problem,” says Olga Feher, an assistant professor at the University of Warwick in England.

    But animal vocalizations and human speech are very different things, says Jamin Pelkey, a professor at Ryerson University. “All species communicate. Unlike other animals, though, human beings are able to use sound patterns for functions that are far stranger—functions that are imaginative, theoretical, and critical. When speech is involved in these stranger functions, that is what we mean by spoken ‘language'.”

    A new study, which was published in the American Journal of Preventive Medicine, found that heavy use of platforms such as Facebook and Snapchat was associated with feelings of being separated from society among young adults—basically the opposite of what we are led to believe.

    Study co-author Brian Primack and his team surveyed 1,787 U. S. adults aged 19 to 32 and asked them about their usage of 11 social media platforms. They also asked participants questions related to social isolation, such as how often they felt left out. The participants who reported spending the most time on social media—over two hours a day—had twice the odds of perceived（感知到的）social isolation than those who said they spent a half-hour per day or less on the same sites.

    According to Tom Kersting, psychotherapist and author of Disconnected, the key to understanding these results lies in our understanding of “connections.” “Humans are social —emotional beings, meaning that it is in our DNA to be connected, face-to-face, with other humans,” he told Reader's Digest. “Although people think being on social media all the time makes them 'connected' to others, they are actually 'disconnected,' because the more time one spends behind a screen, the less time one spend face-to-face.”

    “Part of the issue of loneliness is that the majority of people who use social media aren't just posting, they are also viewing,” Kersting continued. “They are spending a lot of time looking at everyone else's posts, where they are and what they are doing. The constant exposure to everyone else's 'perfect' life experiences causes feelings of being left out.”

    So what's the answer? It's simple, says Kersting. “The solution to this is resisting the temptation to look at everyone else's life. Just focus on your own life, where you're going, what you are grateful for, and what you want to accomplish in this world.”

    When you eat fish, you probably eat it off a plate, using a fork. Well, the dolphins in Shark Bay, Australia, eat their fish from conch（海螺）shells!

    Scientists have found some of these bottlenose dolphins（宽吻海豚）using their large beaks to trap fish in shells underwater. Then, carrying the shells to the surface, they shake out the fish into their mouths and eat them. Clearly, using the conch shells allows the dolphins to catch more fish than they would be able to without such a tool. The technique has been called "conching".

    Researchers noticed dolphins engaging in the behavior a handful of times from 2007 to 2009. This dolphin trend seemed to become popular.

    Simon Allen, a scientist, was surprised to see the conching technique spreading. "In the lasts four months alone, the research team have seen and photographed the behavior no less than six times, possibly even seven," he said in a press release. He thinks the dolphins may be learning conching from one another.

    Dolphins are known to be highly intelligent. The size of their brain is large in proportion（比例）to their body size. Compared with other animals, they have highly developed communication and social skills. This species of dolphin also uses other tools. They will break off pieces of sponges that grow in the ocean, for example, and use them to cover their beaks. This allows them to search for food on the ocean floor without hurting their noses.

    Scientists are going to keep trying to catch the dolphins in the act of conching. They hope to see evidence of the dolphins teaching one another the technique. They also want to know how the dolphins get fish in the conch shell. Do they push the fish into the shell with their beaks? Or do they chase the fish into the shell before carrying them up to eat?

    However they do it, Allen believes these dolphins to be particularly clever. "I wouldn't be too surprised to find such cunning ploys being adopted by Shark Bay's bottlenose dolphins," he said in statement.

    Finding your feet in a new town can be hard, especially if you're covered in fur and don't speak the language. But for pets new to Marlborough, help is at hand.

    Marlborough SPCA and the Railway Café, in Blenheim, have joined forces to help welcome pets and their people to the area with morning teas. They hope the morning teas will get tails and tongues wagging(狗摇摆尾巴）as well as giving advice on how to make the move easier.

    Railway Café owner Leanne Harris came up with the creative plan as a way to help welcome people to the area. Leanne moved to Marlborough from Auckland two years ago and said she first struggled to find friends and feel part of the community. "Coming from Auckland I thought people would open their doors and that there would be neighbors calling round with cake. I expected people to come to me and, of course, it wasn't like that. I did get lonely." "I hope to save newcomers having to wait as long as I did to feel part of it all. I would like to welcome them to the town."

    Free plates of sandwiches, cakes will be offered, for the people, while there will be special yoghurt and banana treats for the dogs. The morning teas will take place in the covered area at the back of the popular café beside the railway station off Grove Rd.

    Leanne said she was happy to devote both her time and effort to giving back to the community and felt the project was a great fit with the SPCA.

    "Volunteering is such an amazing thing to do and it changed things for me completely, and I met some amazing people with similar interests."

    SPCA Op Shop manager Karina Greenall, originally from the United Kingdom, said she also wanted to help. "I can give advice on how to resettle pets, the best parks to go to, where the best walks are and where the Civil Service are in town." There will be volunteering chances too for people where they can help out and hopefully make friends too.

    Will it matter if you don't take your breakfast? A short time ago, a test was given in the United States. People of different ages, from 12 to 83, were asked to have a test. During the test, these people were given all kinds of breakfast, and sometimes they got no breakfast at all. Scientists wanted to see how well their bodies worked when they had eaten different kinds of breakfast.

    The results show that if a person eats a right breakfast, he or she will work better than if he or she has no breakfast. If a student has fruit, egg, bread and milk before going to school, he or she will learn more quickly and listen more carefully.

    The result is opposite to what some people think. Having no breakfast will not help you lose weight. This is because people become so hungry at noon that they eat too much for lunch. They will gain weight (增加体重) instead of losing it. You will lose more weight if you decrease your other meals.
