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.

    Do you often lose things? Don't worry. Now a new tool, which can be connected to any object you might lose, may be the way to solve your problem. The Tile, a small square linked up to your iphone or ipad by means of Bluetooth, lets you see how close you are to your missing item, within a 50-to-150-foot range (范围). If the item goes out of your phone's 150-foot range, it can still be found on other smart phones with the same app.

    When you drive the app on your phone, it shows you, with green bars that increase or decrease, how close or far away you are from the Tile. You can also program it to make a sound when you get close to the Tile. And you can link up your phone with up to ten Tiles. And if your lost object — a dog, for example, or a stolen bike — go out of your own phone's 150-foot Bluetooth range, you can set it as a “lost item”. If any of the phones with the Tile app comes within range of your lost item, a message will be sent to your phone, telling you its position. The Tile app also has the function to remember where it last saw your Tile, so that you can easily find where you left it.

    Since the Tiles use Bluetooth rather than GPS, they are never out of battery or needn't to be charged, and they work for one year before needing to be replaced. And the app works with all generations of iPhones and iPads.

    Scientists used to explore (探测) on the surface of the ocean. Now they are exploring below the surface, too. They want to know about ocean water and the plant and animal life deep in the ocean.

    In 1934 the scientist William Beebe dived 3000 feet below the surface in a hollow steel ball. In 1935 August Piccard dived 10330 feet In I960 his son Jean dived to a depth of 35800 feet. All these early dives were deep. But the divers could not stay down for very long. They had to come back up to the surface after a few seconds. Scientists needed to stay down longer to study life below surface. Gradually they succeeded. Cousteau, a Frenchman, was able to keep men down to a depth of 36 feet for one month and to a depth of 90 feet for a week.

    Now scientists are developing even better equipment. With this new equipment, men can stay below the surface for days or even weeks. In 1962 Cousteau set up a research station 35 feet below the surface. Then, in 1964, he set up another station on the ocean floor of the Red Sea. This was the first undersea station to operate without help from the surface.

    Many countries are now studying undersea living. The former Soviet Union has an undersea laboratory in the Crimean Sea. The United States has a laboratory 50 feet down on the ocean floor off the Virgin Islands. In 1970 five men lived there for two weeks. Then a team of five women scientists stayed in the laboratory. Next came other teams of men. All were there to explore the ocean depths and to make plans for the use of its resources. Scientists hope to find enough mineral, vegetable, and animal wealth there to provide food for the entire world.

    I have three kids and a great husband and I'm enjoying a career that I find challenging and fun. To the outside world, this feels like" Success." But there is still a voice in my heart asking if this is who I truly am. Only in silence do I hear the self and wonder who that person might be.

    So I booked a trip to find out. I travelled, for the first time, without my husband or kids. I went to Iceland with a friend, who shares an appreciation for wilderness and silence.

    For six days, we were immersed(沉浸)in wild, raw scenery and real weather—a11 kinds of weather. Climbing a mountain against rain and returning to a tent for a simple meal reminds you how little you actually need. And how strong it feels to be uncomfortable sometimes.

    I found silence in Iceland, and time to consider the me outside of career and the me out—side of kids as I shared stories with strangers.

    When I stopped talking and just 1istened, I became more generous. I 1earned that choosing to be generous can create more space, more food and more warmth.

But I didn't really gain any better appreciation of what I want from life or my job. I suspect the anxiety that drove me to seek silence in Iceland was losing sight of my ability to choose gratitude and joy, and to be present in the challenges I set in my career and my family.

    I came home to noise, rush and love; with no less confusion on who I want to be. I know the answer isn't waiting out there on the top of a mountain in Iceland. The answer is in front of me with every step on my own life's path, and in every choice I make.

    I.M. Pei, the Chinese-American, who was regarded as one of the last great modernist architects, has died at the age of 102.

    Although he worked mostly in the United States, Pei will always be remembered for a European project: His redevelopment of the Louvre Museum in Paris in the 1980s. He gave us the glass and metal pyramid in the main courtyard, along with three smaller pyramids and a vast subterranean (地下的) addition to the museum entrance.

    Pei was the first foreign architect to work on the Louvre in its long history, and initially his designs were fiercely opposed. But in the end, the French—and everyone else—were won over. Winning the fifth Pritzker Architecture Prize in 1983, he was thought as giving the 20th century "some of its most beautiful inside spaces and outside forms … His talent and skill in the use of materials approach the level of poetry."

    After studying architecture at the Massachusetts Institute of Technology and Harvard, Pei set up his own architectural practice in New York in 1955.

    Designing the John F. Kennedy Presidential Library & Museum in 1964 established him as a name. His East Building of the National Gallery of Art in Washington in 1978 changed people's ideas of a museum. The site was an odd trapezoid (梯形) shape. Pei's solution was to cut it in two. The resulting building was dramatic, light and elegant—one of the first crowd-pleasing cathedrals of modern art.

    Though known as a modernist, and notable for his forms based on arrangements of simple geometric (几何的) shapes, he once urged Chinese architects to look more to their architectural tradition rather than designing in a western style.

    In person, I.M. Pei was good-humored, charming and unusually modest. His working process was evolutionary, but innovation (创新) was never an intended goal.

    "Stylistic originality is not my purpose," he said. "I want to find the originality in the time, the place and the problem."
