    Australian scientists are trying to give kangaroo-style stomachs to cattle and sheep in order to cut the greenhouse gases they send out, which is thought to be responsible for global warming.

    Thanks to special bacteria in their stomachs, kangaroo flatulence (肠胃气胀) contains no methane and scientists want to transfer that bacteria to cattle and sheep who produce large quantities of the harmful gas.

    While the usual image of greenhouse gas pollution is a billowing smokestack, pushing out carbon dioxide, farm animals' passing wind contribute a surprisingly high percentage of total emissions in some countries.

    “Fourteen percent of emissions from all sources in Australia are from enteric methane from cattle and sheep,” said Athol Klieve, a senior research scientist with the greensland state government. “And if you look at another country such as New Zealand, which has got a much higher agricultural base, they are actually up around 50 percent,” he said.

    Researchers say the bacteria also make the digestive process much more efficient and could potentially save millions of dollars in feed costs for farmers. But it will take researchers at least three years to isolate the bacteria before they can even start to develop a way of transferring it to cattle and sheep.

    Another group of scientists, meanwhile, have suggested Australians should farm fewer cattle and sheep and just eat more kangaroos. And about 20 percent of health-conscious Australians are believed to eat the national symbol already.

    It's low in fat, it's got high protein levels and it is very clean in the sense that basically it is free-range(放养的) animal,” said Peter Ampt of the University of New South Wales' institute of environmental studies.

    My husband and I recently went to Disney World with our three children. We had a wonderful time. Besides, I experienced something that left a deep impression on me.

    Our children were excited about the attraction where children could drive the cars. They were so delighted that I decided to stand beside the track to get pictures of everyone as they drove past on the track.

    As I waited for them to drive by, I noticed a car with a father and his son who was about 7 years old. They rolled down the hill at the beginning, but suddenly the car stopped. The young driver looked nervous, "I can't do it." His father quietly said, "Yes, you can."

    "No. I can't!"

    "Yes, you can, son."

    The little guy was almost in tears, "I can't!" With deep patience, the father said, "Son, you can do this. I'm going to help you." A moment later, with the father helping his son, the two went smoothly (顺利地) on their way down the track.

    The scene brought tears to my eyes and it reminded (使想起) me of my dear father. Just like that little boy's dad, my father used to say the same words to me. Every time things got hard or when I experienced setbacks along the way, he would say, "Michelle, you can do this. I'm going to help you."

    Time and time again the words greatly encouraged me on the journey. I'm aware that I can't do things under my own power, but the words "Yes, you can" come beside me and give me wisdom and strength. As I benefited (受益) a lot from them, I often tell my children never to say "I can't" easily when they meet something difficult.

    As Artificial Intelligence(AI) becomes increasingly sophisticated(复杂的), there are growing concerns that robots could become a threat. This danger can be avoided, according to computer science Professor Stuart Russell, if we figure out how to turn human values into a programmable code.

    Russell argues that as robots take on more complicated tasks, it's necessary to translate our morals into AI language.

    For example, if a robot does chores around the house, you wouldn't want it to put the pet cat in the oven to make dinner for the hungry children. "You would want that robot preloaded with a good set of values," said Russell.

    Some robots are already programmed with basic human values. For example, mobile robots have been programmed to keep a comfortable distance from humans. Obviously there are cultural differences, but if you were talking to another person and they came up close in your personal space, you wouldn't think that's the kind of thing a properly brought-up person would do.

    It will be possible to create more sophisticated moral machines, if only we can find a way to set out human values as clear rules.

    Robots could also learn values from drawing patterns from large sets of data on human behaviour. They are dangerous only if programmers are careless.

    The biggest concern with robots going against human values is that human beings fail to so sufficient testing and they've produced a system that will break some kind of taboos(禁忌).

    One simple check would be to program a robot to check the correct course of action with a human when presented with an unusual situation.

    If the robot is unsure whether an animal is suitable for the microwave, it has the opportunity to stop, send out beeps(嘟嘟声), and ask for directions from a human. If we humans aren't quite sure about a decision, we go and ask somebody else.

    The most difficult step in programming values will be deciding exactly what we believe in moral, and how to create a set of ethical rules. But if we come up with an answer, robots could be good for humanity.

    Laughter is a kind of universal body language that is shared by people of all nationalities, skin colors, cultures and traditions. But did you know that the ability to tell real laughter apart from fake (假的) laughter also varies among cultures?

    Greg Bryant, a professor of communication at the University of California, published a study in late July. In the study, 884 people from 21 countries were asked to listen to random recordings of laughter. Some of the recordings were made up of laughs from the bottom of the heart, while others were made by people who were asked to laugh on command.

    The study showed that people around the world have the ability to pick out real laughter, although their abilities vary from country to country. Residents of the Samoan Islands, were particularly good at it, correctly identifying real laughter 56 percent of the time. According to Bryant, people from smaller, less industrialized nations “are more accurate in identifying a natural smile” because they rely heavily on emotional engagement in order to predict others' behavior and create stronger social relationships.

    But how do people from different cultures detect natural laughter so easily? And what characters does real laughter have? As Professor Jessica Wolf of the University of California told the Association for Psychological Science, in real laughter, we produce qualities, such as higher pitch (音调) and volume, as well as faster bursts of no clear sounds.

    By contrast, fake laughter will "sound like speech". According to Science Daily, fake laughter is controlled by the same brain system that controls the lips and tongue. Bryant further explained that this system has active ability, saying "with this speech system, you can make a lot of different noises, including crying, laughter or scream. That's where fake laughter comes from".

    So that? s something to think about: next time one of your friends laughs at something you say, will you be able to tell if it's real or fake?

New research into a long-lived tree has shown some of the tricks that have helped it survive for thousands of years. The ginkgo(银杏树) is a huge, slow-growing tree with fan-shaped leaves, native to China, but planted in parks and gardens across the world. Some of the largest ginkgoes are said to be more than 3, 000 years old.

In order to discover how these and other trees can live for so long, scientists from the US and China studied 34 healthy ginkgoes of different ages. The team studied growth rings in each tree's trunk(树干), as well as cells(细胞) from the bark, leaves and seeds. They found that 600-year-old trees were just as healthy as 2-year-olds.

To learn more, the team then looked in detail at the DNA of nine trees aged between three and 667 years old. DNA is the chemical in the cells of plants and animals that holds instructions that tell any living thing how to grow and develop-including what to do at different times in its life At the beginning of a tree's life, DNA instructs the cells in a seedling to divide quickly so the tree grows rapidly. The cells also make special chemicals to help the young plant survive difficult situations, such as disease. As most trees grow older, their DNA tells their cells to divide more slowly (so growth slows down) and to make fewer chemical defenses(防御).

Ginkgoes, however, do things differently. The team found that although their growth finally slows, both young and old trees make protective chemicals." The secret is keeping a really healthy defense system," said researcher Richard Dixon." As ginkgoes age, they show no sign of weakening their ability to defend themselves from things like disease. "Other trees that live for a long time may have the same ability.

For all their defenses, though, ginkgoes cannot live forever--they finally meet with deadly accidents such as fire, disease and storms. While they last, however, these leafy trees are some of the most beautiful trees in the world.
