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.

    Starting the day on an egg could keep your blood pressure (血压) under control, research suggests. Scientists have shown that eggs produce proteins with a function similar to that of powerful blood pressure-lowering drugs.

    The research, from the University of Alberta in Canada, showed that when eggs come in contact with stomach enzymes (酶) they produce a protein that acts in the same way as Ace inhibitors, but more work is needed to show the effects outside a lab and in the human body.

    Earlier this month, British researchers declared that, contrary to popular beliefs, it is healthy to go to work on an egg. They concluded that the type of cholesterol (胆固醇) found in eggs has little effect on increasing heart disease risks.

    Researcher Professor Bruce Griffin, from the University of Surrey, said: “The wrong beliefs linking egg eating to high blood cholesterol and heart disease must be corrected. The amount of fat in our diet has an effect on blood cholesterol that is several times greater than the relatively small amounts of cholesterol found in eggs. The UK public do not need to be limiting the number of eggs they eat. They can be encouraged to include them in a healthy diet as they are one of nature's most nutritious foods.”

    The British Heart Foundation dropped its three-egg-a-week limit in 2005. However, almost half of Britons believe the limit still applies.

    STA Travel, the world's largest students and youth travel agency, beats any price! Every day we're working with our partners around the globe to get you (students, teachers and anyone under 26) the cheapest and most comfortable flights and top-rated accommodations. This part of www.statravel.com provides great tips for green travel — how to pack, how to leave your house or apartment, and how to plan for your trips. You'll also find a great selection of green travel adventure trips to all corners of the world.

    Green travel means responsible (负责任的) travel! Leave as little influence as possible on the places you visit and protect the environment both at home and during your trip. Think “Green” when you pack and when you travel. You'll help prevent long-term effects on the communities you leave and visit! Here's some advice on how to do that.

    Before you leave

    Turn your water heater to its lowest setting.

    Turn off your water from the outside.

    While you travel

    Pack suitable clothes in your luggage, none of which is to harm the environment.

    Try products made from recycled materials.

    Don't buy souvenirs produced from endangered species.

    Carry a reusable bottle for water and refill it as you go.

    Use the bathroom in the airport, NOT on the plane. The fuel used for a single flush (冲洗) could run a car for six miles.

    Television in the United States is free. To pay for programs, there are many advertisements. Often these advertisements are short plays with actors. The following television advertisement is like many others that Americans see daily.

    We see a man and his wife at the breakfast table. They have been married for a long time. They are not speaking to each other. They haven't spoken to each other at the breakfast table for years. The husband is reading his newspaper. We can't see his face. The wife looks very bored as she pours a cup of coffee for him. Today, she is using a new kind of coffee for the first time. The husband picks up his cup. He isn't very interested. He tastes his coffee. Suddenly he puts down his newspaper. Something is different. Can it be the coffer? He takes another taste. It's wonderful. He smiles. He looks at his wife and says in amazement, “Doris, when did you cut your hair?” Doris is pleased. She answers, “Two months ago.” Doris asks, “Herbie, when did your hair begin to turn grey?” He replies, “A long time ago.” Doues says, “Oh, very handsome.” Now they aren't bored anymore. Breakfast is different. Having a new kind of coffee changed their lives.

    Wolves travel shorter distances and move slower during snowfall events, according to new research by University of Alberta biologists. The effects were most pronounced at night, when wolves hunt, and behaviour returned to normal within a day. Wolf tracks across snow in northeastern Alberta.

    "Our findings suggest that there is something about actively falling snow that causes wolves to slow down," said Amanda Droghini, a former MSc student in the Department of Biological Science and lead author on the study. "We don't know the exact mechanism behind that. It's unlikely that they were staying still because they were feasting on a recent kill. Instead, active precipitation（降雪量）might affect wolves' hunting abilities. Like rain, snow clears the air column of scent molecules. So, maybe falling snow makes it harder for wolves to detect the smell of prey."

    Over the course of two winters, the researchers used remote cameras to disclose snowfall events and estimate snow depth. To study wolf movement, they collected telemetry（测距仪） data from 17 wolves to calculate travel speed and duration, as well as resting periods. It is the first study to examine how large flesh-eating animals respond to snowfall events.

    With the effects of climate change on precipitation in the north forest region uncertain, it is difficult to predict the implications for wolf populations. Studies such as these increase our understanding of how large mammals react to normal snowfall events, but the type and amount of winter precipitation will likely have an impact on animal behavior and the energetic cost of movement.

    "Winter is already challenging for many wildlife species because moving through snow requires more energy. Snow can also make it harder for animals to access food resources," said Droghini, who conducted the research under the supervision of Professor Stan Boutin, Alberta Biodiversity Conservation Chair.

    "Anything that increases those costs, such as increased rain-on-snow events, could lead to lacking in nutrition, poor body condition, and even starvation as animals are unable to make up for those additional costs. That is one of the worst-case scenarios（设想）but, in truth, we know very little about potential changes to precipitation patterns and how wildlife will respond to those changes."

What better way to experience the history of a site than to have a hand in actually preserving it? This was the thought behind the founding of Adventures in Preservation (AIP) in 2001. The nonprofit's founders. Judith Broeker and Jamie Donahoe, were both long time preservationists and world travelers. They had seen a great many buildings in poor condition, as well as buildings that had been "restored" without the benefit of conservation expertise.

Twelve years on, they are still involved in the day-to-day management of the organization, supported by a volunteer staff located around the world, Judith's favorite projects have long been the ones in Eastern Europe, and she enjoys opportunity to travel there each year. She, along with anyone else who's joined an adventure, always quotes their fellow jammers, as they're called, as the highlight of each project. The groups are made up of people from all different ages, occupations, and cultures. Yet each time, they form a strong bond and work so well together that the work becomes fun. Which, after all, is the point of a working vacation, no?

Raising understanding of people's own heritage(遗迹) is another part of AIP projects. In many places, there is so much focus on the news that not only are heritage buildings being lost but so are the traditional building skills needed to keep them. By providing training and raising awareness of the importance of their heritage, AIP is helping keep both alive.

Next year, AIP has projects in Europe and the US. There will be even more projects the following year as projects currently under development in Ghana, Armenia, Ukraine and the US come on line. Each project is also an opportunity for travel, adventure, and personal growth, and AIP welcomes people from around the world to join a project and" "jam" with them.
