“Birds” and “airports” are two words that, paired together, don't normally paint the most harmonious picture. So it really raises some eyebrows when China announces plans to build an airport that's for birds.

Described as the world's first-ever bird airport, the proposed Lingang Bird Sanctuary(保护区) in the northern coastal city of Tianjin is，of course，not an actual airport. Rather, it's a wetland preserve specifically designed to accommodate hundreds — even thousands — of daily takeoffs and landings by birds traveling along the East Asian-Australasian Flyway. Over 50 species of migratory (迁徙的）water birds, some endangered, will stop and feed at the protected sanctuary before continuing their long journey along the flyway.

Located on a former landfill site, the 61-hectare (150-acre) airport is also open to human travelers. (Half a million visitors are expected annually.) However, instead of duty-free shopping, the main attraction for non-egg-laying creatures at Tianjin's newest airport will be a green-roofed education and research center, a series of raised “observation platforms” and a network of scenic walking and cycling paths and trails totaling over 4 miles.

The proposed Bird Airport will be a globally significant sanctuary for endangered migratory bird species, while providing new green lungs for the city of Tianjin,” Adrian McGregor of Australian landscape architecture firm McGregor Coxall explained of .the design. Frequently blanketed in smog so thick that it has shut down real airports, Tianjin is a city — China's fourth most populous — that would certainly benefit from a new pair of healthy green lungs.

    You may have never heard of Lanthanum, Cerium or Neodymium, but these elements (元素) and others known as “rare earth” play a major role in modern technology. They can actually be found in many places on the earth, but not in quantities that can be mined. Only a few countries — China, America, India, Australia, Brazil and Malaysia have any that can be mined enough to be traded.

Even though some of these elements such as Cerium are as abundant as Copper, they are not found in concentrated amounts on the earth's surface. They are often mixed together with other metals, which makes extraction (提取) of these elements an expensive and an environmentally messy process. It was due to this reason that the term “rare earth” was invented.

    Rare earth metals are used widely in our life. Rechargeable car batteries, computers, iPhones, DVD players, computer monitors, televisions, lighting, lasers, glass polishing, and superconductors all use quantities of rare earth metals. Also, with the advancement in “green” technology like solar panels, these shiny materials are becoming more important than ever. An average electric car uses 10 pounds of Lanthanum for its rechargeable battery!

    America has large deposits (存储量) of rare earths and has one of the first mines. It was openedin Southern California in 1940. The element “Europium” was the first metal to be separated in quantity for use in color televisions. However, in the 1980's and 1990's, as China started producing these elements in Inner Mongolia, the mines in America and elsewhere could not keep pace. The mine in Mountain Pass, California also failed environmental regulations and shut down in 2002.

    Now, recognizing the importance of having more than one supplier of this important resource, other rare earth owning countries like India and Australia are either dusting off their rare earth mines or speeding up their production. It is believed that the debate over rare earths will become louder in the coming months and years.

    Mill 180 Park is truly a park for the 2lst century, designed to copy all of the great urban parks -Central Park in New York City, Hyde Park in London and Ueno Park in Tokyo. Through the use of computerized sound and some other modern systems, we've brought the outside in, surrounding our visitors with green space and a remarkable sense of the natural world.

    We spent a lot of time trying to learn why these parks are so beloved, what makes them work so well for their sponsors, and how they provide a place of rest for so many.

    You don't need to get in a time-traveling machine to see how technology will reshape our lives, such as the way we shop. Several new technologies that are to change your buying habits already exist. Let's see what's waiting for your future shopping.

    Try it on, virtually(虚拟的). Want to shop online for a new pair of eyeglasses? You don't need to guess which pair looks best on you. Go and see the eBay Fashion iPhone app to try a pair of eyewear you're checking out on a picture of your face. But what if you want to buy something bigger? Thanks to Microsoft Kinect's motion tracking camera, you can cover clothes on your screen body. You can even choose the background of your virtual fitting room to enrich your shopping experience.

    Get a perfect, custom fit. Everyone's body is shaped differently. To get a perfect fit, you sometimes have to get your clothes changed. But by using 3D scanning(扫描) technology, all the clothes you buy will fit your body perfectly. Some companies scan your body using High-tech to get the most exact sizes, so they can make special clothes just for you.

    Experience high-tech shopping carts and checkout counters. High-tech shopping carts could, in time, be a common sight in malls and supermarkets. Microsoft Kinect-enabled carts are under test at present. The cart can follow you along the aisles (通道), controlled only by your movement and your voice. In China, a supermarket chain(连锁超市) introduced tablet-equipped carts that guide shoppers around the stores' aisles.

    In the United States, several supermarkets use a device(装置) called Scan It that gives buyers the freedom to scan goods on their own while they shop. While it's great not having to line up at a checkout counter, we wouldn't mind it if the store used Toshiba's new Object Recognition Scanner. The machine identifies(辨认) a product as soon as it's placed in front of a camera just by its shape and color, even if it has no bar code(条形码).

If you are a psychology enthusiast, you have probably heard of the famous marshmallow (棉花糖) test. In this task, kids are given a single treat, such as a marshmallow, and are told that they can eat that marshmallow now, or they can wait a little while, and have two marshmallows instead.

Some kids eat the marshmallow immediately, but most try their best to wait for the experimenter to come back with two marshmallows.

Wait times in the marshmallow test came to be seen as indicators of self-control. But what if the behavior in the marshmallow test has more to do with cultural norms (准则) than self-control? A 2022 study by Yanaoka tested the idea that children may decide how long to wait for rewards based on what they are accustomed to waiting for in their culture. In the United States (with some exceptions), there is no widespread custom of waiting until everyone is served to eat your food. However, in Japan, there is a mealtime custom of waiting until everyone has been served before anyone digs in.

Because of this difference in norms, the researchers assumed that Japanese children would wait longer in the marshmallow test than the American children. This is exactly what they found. The researchers did a clever follow-up experiment. They found one field where children in the U.S. are accustomed to waiting longer than Japanese children are: Opening presents. In the U.S., gifts are usually given on special occasions, such as birthdays and Christmas. On these occasions, children usually have to wait before they can open their presents. In Japan, however, gift-giving happens more often, and children usually open presents immediately.

Given these cultural differences, Yanaoka expected that if they ran the marshmallow test with Japanese and American kids, but they replaced marshmallows with packaged gifts, then American kids would wait longer to open them. Once again, their assumption was correct. When the potential rewards were packaged gifts instead of food, American children waited 15 minutes on average, and Japanese children waited about four minutes on average.

This is a powerful result because it demonstrates the importance of culture and habit in shaping behavior. If a child waits only four minutes before giving up on two marshmallows but then waits almost four times longer to open a gift, can we really say that that child lacks self-control? I don't think so.
