    To save as much language diversity as possible in the face of its rapidly dying out, researchers suggest using “evolutionary trees”, a tool from conservation biology.

    One of the world's 7,000 languages disappears every other week, and half might not survive the 21st century, experts say.

    When setting conservation goals, ecologists use evolutionary trees—diagrams that show how biological species are related to one another—to identify species that have few close relatives. Such species are said to be evolutionarily distinct. Similarly, recent advances in the construction of language trees make it possible to measure how unique a language is.

    “Evolutionary trees have transformed our understanding of how life has evolved and helped us to decide which species most need conserving,” says Jonathan Davies, senior author of the new study.

    “The rapid rate of language loss, as well as limited resources for preservation(保护), means that we must choose carefully where to focus our efforts,” adds Max Farrell, a PhD student in Davies' lab. “The more isolated (孤立的) a language in its family tree, the more unique information it contains and eventually contributes to language diversity.”

    As a case study, they used this approach to rank 350 Austronesian languages, spoken in islands spread across Southeast Asia and the Pacific Ocean.

    For each of these languages, the researchers combined measures of evolutionary distinctiveness (ED) and global endangerment (GE) to produce an “EDGE” score. The language with the highest score, which means it is extremely distinct(不同的) yet nearly dying out, was Kavalan, a language native to Tai Wan. The next-highest scores went to Tanibili, an endangered language in the Solomon Islands.

    By building trees for other language groups, language specialists could target preservation efforts and help reduce the loss of language diversity in the future, the researchers say.

    My students entered the art room with their usual eagerness to see what they would be learning in today's class. Little did they know they were going to be students for a new teaching method that is spreading the nation.

    I often use videos as previews and supplements (补充) to our art lessons providing students with a variety of artists showing their skills in real-life situations outside the classroom. Finding a new painting technique called glue batik(胶水蜡染),  I thought of something new I hadn't tried before!  How awesome would it be to learn a new technique together with artists? The lesson was planned, presented to the students without any introduction or set objectives. I also asked the students to watch and pause the video as often as they needed to.

    They watched as the artist explained and showed her skills, taking notes on her steps and results. After the video, they shared what they felt the artist's objectives were, her end result using art vocabulary as well as the steps they would need to know to present their own examples. Then they began creating their works using the glue batik technique.

    Surfing the Internet a couple of weeks later, I found that the teaching method I used sounded very familiar to a new movement in education called flipped teaching, which was developed by Jonathan Bergmann. He asked his students to watch video lectures at home and do exercises (homework) in class under supervision (监督). He found that grades went up and he also found time for other types of activities, which Bergmann states are more important than the videos.

    Back to my art class, the students were learning to get ideas, make predictions, and explain reasoning to their classmates. Together they compared, asked questions and made discoveries as they presented the technique.

    Stefano Boeri, the Italian architect, famous for his Bosco Verticale, a group of tree-covered skyscrapers in Milan, introduced his new plans to pioneer a similar project in the Chinese city of Nanjing.

    The Chinese version of Boeri's Bosco Verticale, or vertical forest, will be his first project in Asia. The project will consist of two neighboring towers that will be coated with 23 different species of trees and more than 2,500 kinds of bushes hanging down the sides of the buildings. The structures will be built with the ability to house offices and will feature a 247-room luxury hotel, as well as a museum and even a green architecture school. The towers are currently under construction and are set for completion within the next year.

    But two buildings aren't enough for the ambitious Boeri as he now has even bolder plans for China to create “forest cities” in a country that has become known as an urban center choking on poisonous gases and dust.

    In an interview about his plans to “greenify” the city and country Boeri said, “We have been asked to design an entire city where you don't only have one tall building, but you have 100 or 200 buildings of different sizes, all with trees and plants on the sides.” Boeri continued, “We are working very seriously on designing all the different buildings. I think they will start to build at the end of this year. By 2020 we could imagine having the first forest city in China.”

    Although these towers will lend a huge hand in decreasing air pollution in China's eastern city, Boeri has said, it will take more than a pair of tree-covered skyscrapers to really solve China's pollution crisis. This is why the Italian architect hopes to repeat his design in other parts of the country, as well as in other places around the world.
