Australian cities can keep their native wildlife — but only if they can kick their habit of urban sprawl (扩展). That's the finding of a new study by leading Australian environmental researchers Jessica Sushinsky, Professor Hugh Possingham and Dr. Richard Fuller of The University of Queensland.

    “While urban development usually reduces the number of birds in a city, building more compact (紧凑的) cities and avoiding urban sprawl can slow these reductions greatly,” says lead author Jessica Sushinsky. “Compact housing development leaves birds' homes untouched, leading to fewer losses of birds.”

    The researchers surveyed native and wild birds in Brisbane's urban areas, including living and industrial areas, public parks and gardens, major roadways and airports. They then used statistical modeling to find out what will happen to the birds as the city grows. The first setting was compact growth — where multiple homes are built on land that previously had only one house. The second setting was sprawling growth — a familiar pattern where homes are built here and there beyond the city's current boundaries.

    The team's forecasts showed that a much greater diversity of species was lost over 20 years in the sprawling setting compared to the more compact setting. “Urban sprawl resulted in the disappearance of many urban-sensitive birds — birds that only live in areas where there is native vegetation (植被), such as parklands and woodlands,” Ms. Sushinsky says.

    “On the other hand, we found the city with the compact development attracted more birds because it kept more of its parks and green areas.”

    Now the Queensland Government has adopted the more compact urban growth strategy, which, Dr. Richard Fuller says, is good news for Australia's native birds. These birds are environmental specialists — they need a particular environment to do well. “While compact development means smaller backyards, it can also make our entire cities more biodiverse,” according to Dr. Fuller. “The study shows that we should hold on to our green spaces instead of clearing them for sprawling development.”

    This is the first time science has modeled the effects of different urban growth strategies on birds, the researchers say. “Statistical models like these are important because they help us to understand the ecological consequences of a particular decision,” says Dr Fuller.

    Next time you make yourself a hot cup of tea or coffee, you might want to let it cool down a bit before drinking.

    Researchers say letting your hot drinks cool off could help you avoid some kinds of cancer. Researchers at the International Agency for Research on Cancer (IARC) found evidence that drinks at temperatures above 65℃, when swallowed, can cause cancer of the esophagus (食道). The researchers examined findings from other studies where tea and coffee were often served at 70℃ or above. Those studies were completed in Iran, China and South America.

    In developed countries, health experts have linked esophageal cancer to smoking and alcoholic（酒精）drinks. However, this form of cancer is more common in areas where people drink beverages（饮料；酒水）at very high temperatures.

    In Europe and the United States, many people drink coffee and tea at temperatures around 60℃.And they often add milk which lowers the temperature greatly. However, tea-drinkers in Iran and mate-drinkers in South America often enjoy their beverages at closer to 70℃.

    The researchers find that South Americans not only drink their mate very hot, they also drink it through a metal straw(吸管). This sends the scalding liquid directly into the throat.

    The findings, however, are good news for coffee drinkers. In 1991, the World Health Organization listed coffee as possibly carcinogenic (致癌的).” The WHO officials have since changed their position on that listing. They now suggest that the temperature of your hot drink is a greater risk factor than the actual drink itself.

    The results suggest that drinking very hot beverages is one probable cause of esophageal cancer and that it is the temperature, rather than the drinks themselves, that appears to be responsible.

    Art museums are places where people can learn about various cultures. The increasingly popular "design museums" that are opening today, however, perform quite a different role. Unlike most art museums, the design museums show objects that are easily found by the general public. These museums sometimes even place things like fridges and washing machines in the centre of the hall.

    People have argued that design museums are often made use of as advertisements for new industrial technology. But their role is not simply a matter of sales — it's the honouring of excellently invented products. The difference between the window of a department store and the showcase(玻璃陈列柜) in a design museum is that the first tries to sell you something, while the second tells you the success of a sale.

    One advantage of design museums is that they are places where people feel familiar with the exhibits. Unlike the average art museum visitors, design museum visitors seldom feel frightened or puzzled. This is partly because design museums clearly show how and why mass-produced products work and look as they do, and how design has improved the quality of our lives. Art museum exhibits, on the other hand, would most probably fill visitors with a feeling that there is something beyond their understanding.

    In recent years, several new design museums have opened their doors. Each of these museums has tried to satisfy the public's growing interest in the field with new ideas. London's Design Museum, for example, shows a collection of mass-produced objects from Zippo lighters to electric typewriters to a group of Italian fish-tins. The choices open to design museums seem far less strict than those to art museums, and visitors may also sense the humorous part of our society while walking around the exhibits.

    If you are the kind of tourist who likes to visit places with outstanding landscapes and multicultural cities, then Asia is the place to go. Take a cruise(巡游)to Asia and you will not be disappointed.

    The Finest Asian Cruise Explorations

    Tourists who want to visit several Asian countries understand that cruising there is the best alternative. You can decide to take a two-week cruise, starting from Sri Lanka to Thailand. There's also a three-week cruise that starts off in China all the way to Japan. A most popular voyage is one that starts from Hong Kong to Singapore.

    The Best Time to Travel

    When touring Asia, it's best to understand that different cruise lines have different travelling timelines. You can be caught in the rain during your tour(October to December in Malaysia and December to February in Indonesia). Most cruises take place from December to the end of March.

    Booking Cruise-ship Tours

    Given that you'll probably be taking long flights to get to South Asia and the Far East, the budget will be large, especially if you are visiting as a family. In addition, many people tour this region, so it would be best if you book early when the prices are more appealing.

    Activities

    There are so many ports in Asia and this might bring a challenge if you want to get somewhere in time. Make sure you plan your day-trips in advance and follow the cruise line tours to avoid missing the boats. Apart from visiting the cities, you could also go to Borneo, Indonesia to see the orangutans(猩猩). You can also hop across several islands from Bali, appreciate the colorful floats as well as the cherry blossoms in Japan and visit the floating fish farms in Vietnam.

    China will follow up on its successful mission (任务) to the far side of the moon by sending a probe to Mars next year, one of its top space scientists said Sunday. Wu Weiren, chief designer of China's lunar exploration program, said the red planet was the natural next step. "Next year we'll launch a Mars probe to orbit around the Mars, land on it and probe it," he said. China will also send another probe to take back samples from the moon's surface.

    Wu's comments came as a Mars simulation(模拟) base opened in Qinghai's Qaidam Basin. According to the state-run Global Times, while the red rocky area bears a strikingly similarity to Mars, it's extremely difficult to simulate Mars due to its special natural features and hostile environment—low air pressure, strong radiation and frequent sandstorms, as well as vast differences in geography.

    China didn't send its first satellite into orbit until 1970, by which time America had already landed an astronaut on the moon, but it's been catching up fast. Since 2003, China has sent six crews into space and two space labs into Earth's orbit. In 2013, China successfully landed a rover, Yutu 1, on the moon, becoming only the third country to do so.

    Last December, China landed another probe and a rover, Yutu 2, on the far side of the moon. Progress has been slow going since then: due to the extreme conditions there, the rover often has to hibernate to preserve its capabilities for further exploration, Wu said. "The temperature there is minus 190 degrees Celsius, which all components and parts cannot stand. So we let it sleep for a while, making sure it can spend the night safely. A few days ago, it woke up automatically to work. We've gained lots of data in the past few days, and we're going to make the data known to the world,” Wu said.
