Though there are about 400 languages from all over the world that are in danger of disappearing completely，Zoque-Ayapaneco，a native Mexican language is considered the most likely to become extinct，because the only two people in the world that speak it fluently do not talk to each other!

    And，it's not because they live in different countries，states or even villages. In fact，Manuel Segovia and Isidro Velazquez，both in their 70s，live within 500 yards of each other，in the village of Ayapa in the Southern Mexican State of Tabasco. They，however，refuse to communicate because they simply don't have much in common. Segovia is apparently a little frank in nature while Velazquez is described as shy.

    Segovia was at least able to talk in Zoque-Ayapanece with his brother until he passed away about 12 years ago，and still manages to practice it with his family，especially his son Manuel，who for the last five years has been trying to learn it and hopes to become fluent enough to teach it to the next generation. Velazquez on the other hand，has not been heard speaking in the language with anybody.

    The two men say the language used to be widely spoken in the village，but the younger generation refused to learn it for fear of being laughed at，and it therefore began to die a slow death，as the elders passed away.

    Unless the two men get their acts together，the only way to hear the language will be to either listen to Manuel's not-so-fluent statement or see them talk in a documentary entitled “Lengua Muerta” (Dead Language) that is being filmed to capture Zoque Ayapaneco and 364 other native Mexican languages that are in a similar state.

    We sure hope Segovia and Velazquez soon find something common to talk about. Maybe the fact is that the language is dying and that they should start encouraging and teaching the next generation together.

    First Lady Michelle Obama is on a five-day trip to Asia. She is visiting Japan and Cambodia to help publicize a program called "Let Girls Learn". Administration officials set up the campaign to support the education of millions of girls worldwide.

    Before her trip, Mrs. Obama and her husband noted the inability of an estimated 62-million girls to attend school. They said educating the girls should be a foreign policy goal.

    This week, Mrs. Obama criticized the fact that tens of millions of girls are not receiving a satisfactory education. In her opinion piece, she wrote this failure to educate girls it was more than "a tragic waste of potential." It is both a serious public health issue and a problem for the economic health of nations and the world. She also said it was "a threat to the security of countries around the world".

    The First Lady noted by 2012, every part of the developing world was educating both girls and boys in primary schools. But this is not the case in secondary education. She wrote in some areas girls face "the cultural values and practices that limit the prospects of women in their societies ".

    The Obama administration launched the "Let Girls Learn" campaign earlier this month. At the time, Mrs. Obama noted plans to involve the U.S. Peace Corps, and the Volunteer Development Agency.

    "This effort will draw on the talent and energy of the nearly 7,000 Peace Corps volunteers serving in more than 60 countries. Through this effort, Peace Corps will be supporting hundreds of new community projects to help girls go to school and stay in school. And, I want to emphasize that these programs will be community-generated and community-led. They will be based on solutions devised by local leaders, families and yes, even the girls themselves."

    President Obama also spoke at the same White House event, saying that campaign is important to his administration.

“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.

    The more interested you are in a topic, the more likely you may be to form “false memories” about the events related to that topic.

    “Most people are pretty confident about their own memory for some events, but new research shows that false memory is a lot more frequent than many people realize. In terms of daily life, the key point here may be to understand that someone who remembers an event differently from yours isn't necessarily lying—someone's memory may be faulty, or it might be you,” said study co-author Ciara Greene, a psychologist at the university College Dublin.

    In the study, the researchers asked 489 people to read four news stories about events that were related to the topics they ranked as the most interesting, and four stories about events related to the topics they rated as the least interesting. In each case, three of these events really did occur, but the fourth one was made up.

    It turned out that people tended to remember the stories of the topics they said they were more interested in compared with the topics they were not interested in. However, the participants also tended to store more false memories related to the topics they were interested in compared with the topics they were not interested in, the researchers found.

    The more people know about a topic, the more memories related to this topic they have stored in their brains, the researchers said. Therefore, when a person meets new information on this topic, that information may find traces of similar memories that have already stored in the brain, Greene said.

    “This can result in a sense of familiarity or recognition of the new material, leading to the conviction (确信) that the information has been met before and is in fact an existing memory,” Greene said. In other words, this new material or information may “feel” familiar and therefore the person may believe it must be true, he said.

    Learning more about how false memories work may help protect against the harmful results of them, such as when eyewitness accounts(证言) of crimes are faulty.
