    Every year, hundreds of millions of Monarch Butterflies(黑脉金斑蝶) from Canada and the United States journey as far as 2, 500 miles to the forests of Michoacan, Mexico, a place which has the world's largest insect migration(迁移). It's such a breathtaking sight, but as always, human greed is threatening to destroy it.

    The Monarch Butterflies start to arrive in Michoacan in late October to make their winter home in the trees high up in the mountains of the natural reserve. Once there, they gather together in large masses. These masses often become so heavy that they cause tree branches to bend or even break. But there's a purpose of all these massing — it allows the butterflies to survive in the low nighttime temperatures at these high altitudes.

    The Michoacan Monarch Butterfly Sanctuary is most impressive during the months of February and March, just before the winged insects begin their long journey home.

    Mexico's Butterfly Forest is a shelter protected by law, and one of the country's most popular sights, but that hasn't stopped people from slowly but steadily destroying it.

    Illegal woodcutting in the heart of the Monarch Butterfly Biosphere Reserve has been a longstanding problem, but criminals are rarely brought to justice. They are often set free after paying some money.

    Just last month, an even greater threat rose in Michoacan's butterfly home.  The country's largest mining corporation gained the right to reopen an old mine in the heart of the monarch reserve. Experts believe that if the mine is reopened, it will likely spell the end of this magical place.

    And as if all this wasn't bad enough, the increasing use of herbicides（除草剂） in the American corn belt has led to the decrease of  a plant which is essential to the monarchs' development from egg into butterfly.

     Scientists have found living organisms trapped in crystals(晶体) that could be 50,000 years old.

     The organisms were found in a hot, but beautiful cave system in Naica, Mexico. These ancient life forms can be seen only with a microscope. Penelope Boston, who leads the Astrobiology Institute at NASA, the space agency of the United States, says the ancient microbes(微生物) were able to live by eating minerals such as iron.

     She spoke about the discovery recently at a meeting of the American Association for the Advancement of Science. If the findings are confirmed, they will show how microbes can survive in extreme conditions. Forty different kinds of microbes and some viruses were found in the underground area. The genetic structures of these organisms are 10 percent different from those of their nearest relatives.

     The caves in Naica are 800 kilometers deep. They were once used for mining lead. Before the miners began working in the caves, the area was separated from the surface and the outside world. Some of the caves are as big as the large religious centers built during Europe's Middle Ages. There are crystals covering the walls. The caves are so hot that scientists must wear special clothing to keep cool. The clothing keeps the crystals safe from human germs（病菌）or other damage. Boston said the researchers could only work for about 20 minutes at a time before they had to go to a room that was 38 degrees Celsius to cool down.

     NASA officials would not let Boston share her findings with scientific experts before last week's announcement. So scientists could not say much about the findings. But Norine Noonan, a biologist with the University of South Florida, said she believed them. "Why are we surprised?" Noonan asked. "As a biologist, I would say life on Earth is extremely tough and extremely colorful."

     Boston is also studying microbes commonly found inside caves in other countries, such as Ukraine and the United States. These microbes appear to be impossible to kill. Boston said they show how difficult life on Earth can be.

    I had an experience some years ago, which taught me something about the ways in which people make a bad situation worse by blaming themselves. One January, I had to hold two funerals on successive days for two elderly women in my community. Both had died “full of years”, as the Bible would say. Their homes happened to be near each other, so I paid condolence(吊唁) calls on the two families on the same afternoon.

    At the first home, the son of the deceased(已故的)woman said to me, “If only I had sent my mother to Florida and gotten her out of this cold and snow, she would be alive today. It's my fault that she died.” At the second home, the son of the other deceased woman said, “If only I hadn't insisted on my mother's going to Florida, she would be alive today. That long airplane ride, the sudden change of climate, was more than she could take. It's my fault that she's dead.”

    You see that any time there is a death, the survivors will feel guilty. Because the course of action they took turned out bad, they believe that the opposite course would have turned out better. After all, how could it have turned out any worse?

    There seem to be two elements involved in our willingness to feel guilty. The first is our pressing need to believe that the world makes sense, that there is a cause for every effect and a reason for everything that happens that leads us to find patterns and connections both where they really exist and where they exist only in our minds. The second element is the view that we are the cause of what happens, especially the bad things that happen. It seems to be a short step from believing that every event has a cause to believe that every disaster is our fault. The roots of this feeling may lie in our childhood.

    A baby comes to think that the world exists to meet his needs, and that he makes everything happen in it. He wakes up in the morning and summons the rest of the world to its tasks. He cries, and someone comes to attend to him. When he is hungry, people feed him, and when he is wet, people change him. Very often, we do not completely outgrow that childish view that our wishes cause things to happen.

    A child who suffers bullying(霸凌) usually has low self-esteem and their ability to learn and be successful at school is greatly lessened. Therefore, bullying must be stopped.

    The best and most obvious way to stop bullying in schools is for parents to change the way they raise their children at home. Of course, this is much easier said than done and everyone raises their children differently. Bullies, however, come from homes where physical punishment is used and children have been taught that physical violence is the way to handle problems and “get their way”. Bullies usually also come from homes where the parents fight a lot, so children have been modeled on such violence. Parental involvement is often lacking in bullies' lives and there seems to be little warmth.

    Early intervention (干预) is truly the best way to stop bullying, but parents of the victims or therapists(治疗师) can't alter the bully's home environment. Some things can be done at the school level, however. Most school programs that address bullying apply a multi-faceted(多层面的) method to the problem.

    Hand out questionnaires to all students and teachers and discuss if bullying is occurring. Define exactly what constitutes(构成) bullying at school. The questionnaire is a wonderful tool that allows the school to see how widespread bullying is and what forms it is taking. It is a good way to start to solve the problem.

    Get the children's parents involved in a bullying program. If parents of the bullies and the victims are not aware of what is going on at school, then the whole bullying program will not be effective. Stopping bullying in school takes teamwork and concentrated effort on everyone's part. Bullying also should be discussed during parent-teacher conferences and PTA meetings. Parental awareness is the key.

    In the classroom setting, all teachers should work with the students on bullying. Oftentimes even the teacher is being bullied in the classroom and a program should be set up to teach about bullying. Children understand modeling behaviors and role-play and acting out bullying situations is a very effective tool. Have students role-play a bullying situation.

    Do women make BETTER astronauts? Russia locks an all-female crew in space simulator (太空模拟器) for eight days to find out. Six Russian women have been sent into a spaceship to begin a unique experiment testing how an all- female crew would relate to others on a trip to the Moon and back.

    "It's interesting for us to see what is special about the way a female crew communicates," said Sergei Ponomaryov, the experiment's leader." it will be particularly interesting in terms of psychology," said the institute's director Igor Ushakov. "I'd like to wish you a lack of conflicts, even though they say that in one kitchen, two housewives find it hard to live together," he added.

    The volunteers include scientific researchers, a doctor and a psychologist. The test period simulates (模仿) a flight to the Moon and back, with the women carrying out 10 experiments covering psychology and human biology. Russia sent the first woman into space, Valentina Tereshkova, in 1963 but has fallen behind since. Last year, it sent its fourth female astronaut into space, Yelena Serova. Serava complained of a great deal of media interest in how she would wash her hair aboard the International Space Station, pointing out that male astronauts did not face the same line of questioning.

    The women found themselves fielding questions at a press conference about how they would act without men or makeup for eight days, "We are very beautiful without makeup," said participant Darya Komissarova. Her colleague Anna Kussmaul was more direct: "We are doing work. When you're doing your work, you don't think about men and women." They plan to spend their 11/2 hours per day of free time watching films, reading and playing board games. Team leader Yelena Luchnitskaya said she expected the women to deal with any conflict.
