Humans have been keeping animals as pets for tens of thousands of years, but Dr Jean-Loup Rault, an animal scientist at the University of Melbourne in Australia, believes new companions are coming: robot pets.

    “Technology is moving very fast,” Rault told ABC News, “The Tamagotchi in the early 1990s was really the first robotic pet, and now Sony and other big companies have improved them a lot.”

    This may not sit well with pet lovers. After all, who would choose a plastic toy over a lovely puppy? But Rault argues that the robotic kind has a lot going for it: “You don't have to feed it, you don't have to walk it, it won't make a mess in your house, and you can go on a holiday without feeling guilty.” The technology also benefits those who are allergic to pets, short on space, or fearful of real animals.

    It's not clear whether robot pets can replace real ones. But studies do suggest that we can bond with these smart machines. People give their cars names and kids give their toy animals life stories. It's the same with robots. When Sony stopped its repair service for its robot dog Aibo in March 2014, owners in Japan held funerals.

    As an animal welfare researcher, Rault is concerned about how robotic pets could affect our attitudes towards live animals. “If we become used to a robotic companion that doesn't need food, water or exercises, perhaps it will change how humans care about other living beings,” he said.

    So are dogs and cats a thing of the past, as Rault predicts? For those who grew up with living and breathing pets, the mechanical kind might not do. But for our next generation who are in constant touch with smart technology, a future in which lovely pets needn't have a heartbeat might not be a far-fetched dream.

    I was wandering around the Albuquerque International Support airport. My flight had been delayed and I heard an announcement: “If anyone near Gate A-4 understands Arabic（阿拉伯语）, please come to the gate immediately.” Gate A-4 was my own gate. I went there.

    An older woman was crumpled（蜷缩成一团的）on the floor, crying loud. In her traditional Palestinian dress, she reminded me of my grandmother.

    “Talk to her,” urged the flight agent. “We told her the flight was going to be late, and she did this.”

    I bent over to put my arm around the woman and spoke uncertainly. “Shu-dow-a, shu-bid-uck, habibti? Stanischway, min fadlick, shu-bit-se-wee?” She stopped crying. She thought the flight had been called off. She needed to be in El Paso for a medical treatment the next day. I said, “You'll get there, just late. Who is picking you up? Let's call him.”

    We called her son. In English, I told him that I would stay with his mother until we got on the plane. She talked with him. Then we called her other sons just for fun. Then we called my dad and they spoke for a while in Arabic and found out that they had several shared friends. After that, I called some Palestinian poets I knew and let them chat with her.

She was, laughing a lot but then, patting my knee and answering questions. She pulled a bag of homemade cookies filled with dates and nuts and topped with sugar from her bag and offered them to the people at the gate. To my amazement, no one declined. It was like a sacrament（圣餐）. The traveler from Argentina, the mom from California, the lovely woman from Laredo— We were all smiling, covered with the same sugar.

    I looked around the gate and thought. This is the world I want to live in, one with no anxiety. This can still happen anywhere, I thought. Not everything is lost.

    China is fondly remembering one of its most famous radio voices, a man whose vivid storytelling was a comfort to millions of people, from commuters stuck in traffic to restless teens struggling to sleep. Shan Tianfang, was a leading performer of the traditional Chinese art form pingshu, which translates as "storytelling".

    Pingshu dates from the Song Dynasty (AD960-1279) when performers would entertain villagers by telling stories in a particularly emotive style. It remains particularly popular in north-eastern China. Performers wear traditional dress and use very basic props - often a folded fan and a gavel. Pingshu is sometimes performed in tea houses and small theatres, but many Chinese associate the art form with radio. And in a country where sleeping problems are commonplace, pingshu is still popular as a way of helping people to wind down at bedtime.

    Shan Tianfang was born in 1934 in Yingkou, in north-eastern Liaoning province. His family introduced him to folk arts from a young age and he began learning pingshu when he was 19. He became known in Liaoning for his work on stage and in local teahouses during the 1950s and 1960s, and performed in an art troupe around the region. From 1966-1976, Shan, along with other pingshu performers like Yuan Kuocheng, was forced to stop work. During the 1980s.Shan made the transition (转型) to state-run radio, and his captivating storytelling became comfort listening for people across the country. By the 1990s, Shan had become a well-known face on state TV, even performing in the annual Spring Festival Gala show. He has died aged 84 following a long illness.

    Shan performed over 12,000 stories on TV and radio. His stories attracted people of all ages. One of his most acclaimed performances is of the Heroes in the Sui and Tang Dynasties. He gave countless performances of the “Four Classic Novels” (Romance of the Three Kingdoms, Journey to the West, Dream of the Red Chamber and Water Margin) and also helped to bring lesser-known classical Chinese literature to new audiences.

    He was able to use the medium to entrance his audience and in the process he helped to popularise classical Chinese literature. As film director Zhang Jizhong told the Global Times newspaper: “He could describe a scene and a character extremely vividly. He once had a long talk with me about adapting the heroic stories he told into films or television shows to help promote Chinese classics and traditional culture.”

    But in his later years, the growth of online and digital media exposed the challenges of keeping his art form alive. Shan turned his efforts towards writing books and opening performance schools to teach pingshu to young people. They included the Shan Tianfang Culture and Media Academy in Beijing, a Shan Tianfang teahouse and “storytelling base” in Anshan in Liaoning province. Meanwhile, modern productions of pingshu reference (引用，参照) contemporary  (现代的) culture to draw in new performers and audiences. Performers like Guo Heming have emerged, putting a modern spin on pingshu by adapting popular works, including the Harry Potter stories.

    Although he wasn't particularly active on social media, he amassed more than one million fans on the Sina Weibo platform.

A memorial was held for him on 15 September but millions of Chinese will miss his voice.

    Mandara seemed to know something big was about to happen. So she let out a yell, caught hold of her 2-year-old daughter Kibibi and climbed up into a tree. She lives at the National Zoo in Washington D. C.

    And on Tuesday, August 23rd, witnesses said she seemed to sense the big earthquake that shook much of the East Coast before any humans knew what was going on. And she's not the only one. In the moments before the quake, an orangutan（猩猩）let out a loud call and then climbed to the top of her shelter.

    “It's very different from their normal call,” said Brandie Smith, the zookeeper. “The lemurs（monkeylike animals of Madagascar）will sound an alarm if they see or hear something highly unusual.”

    But you can't see or hear an earthquake 15 minutes before it happens, can you? Maybe you can—if you're an animal. “Animals can hear above and below our range of hearing,” said Brandie Smith. “That's part of their special abilities. They're more sensitive to the environment, which is how they survive.”

    Primates weren't the only animals that seemed to sense the quake before it happened. One of the elephants made a warning sound. And a huge lizard（蜥蜴）ran quickly for cover. The flamingoes（a kind of birds）gathered before the quake and stayed together until the shaking stopped.

    So what kind of vibrations（震动）were the animals picking up in the moments before the quake? Scientist Susan Hough said earthquakes produce two types of waves—a weak “P” wave and then a much stronger “S” wave. The “P” stands for “primary”. And the “S” stands for “secondary”. She thinks the “P” wave might be what sets the animals off.

    Not all the animals behaved unusually before the quake. For example, Smith said the zoo's giant pandas didn't jump up until the shaking actually began. But many of the other animals seemed to know something was coming before it happened. “I'm not surprised at all,” Smith said.

    The Healthy Habits Survey shows that only about one third of American seniors have correct habits. Here are some findings and expert advice.

    ⒈How many times did you brush your teeth yesterday?

Finding: A full 33% of seniors brush their teeth only once a day.

Step: Remove the 300 types of bacteria in your mouth each morning with a battery-operated toothbrush. Brush gently for 2 minutes, at least twice a day.

    ⒉How many times did you wash your hands or bathe yesterday?

Finding: Seniors, on average, bathe fewer than 3 days a week. And nearly 30% wash their hands only 4 times a day—half of the number doctors recommend.

Step: We touch our faces around 3,000 times a day—often inviting germs(病菌）to enter our mouth, nose, and eyes. Use toilet paper to avoid touching the door handle. And, most important, wash your hands often with running water and soap for 20 seconds.

    ⒊How often do you think about fighting germs?

    Finding: Seniors are not fighting germs as well as they should.

    Step: Be aware of germs. Do you know it is not your toilet but your kitchen sponge (海绵）that can carry more germs than anything else? To kill these germs, keep your sponge in the microwave for 10 seconds.
