Recordings of angry bees are enough to send big, tough African elephants running away, a new study says. Beehives (蜂窝)—either recorded or real—may even prevent elephants from damaging farmer's crops.

    In 2002, scientist Lucy King and her team found that elephants avoid certain trees with bees living in them. Today, Lucy wants to see if African honeybees might discourage elephants from eating crops. But before she asked farmer to go to the trouble of setting up beehives on their farms, she needed to find out if the bees would scare elephants away.

    Lucy found a wild beehive inside a tree in northern Kenya and set up a recorder. Then she threw a stone into the beehive, which burst into life. Lucy and her assistant hid in their car until the angry bees had calmed down. Next，Lucy searched out elephant families in Samburu National Reserve in northern Kenya and put a speaker in a tree close to each family.

    From a distance, Lucy switched on the pre-recorded sound of angry bees while at the same time recording the elephants with a video camera. Half the elephant groups left the area within ten seconds. Out of a total of 17 groups, only one group ignored the sound of the angry bees. Lucy reported that all the young elephants immediately ran to their mothers to hide under them. When Lucy played the sound of a waterfall (瀑布) instead of the angry bees to many of the same elephant families, the animals were undisturbed. Even after four minutes, most of the groups stayed in one place.

    Lucy is now studying whether the elephants will continue to avoid the sound of angry bees after hearing it several times. She hasn't tested enough groups yet to know, but her initial (最初的) results were promising enough to begin trials with farmers. She has now begun placing speakers in the fields to see if elephants are frightened away.

    Almost every machine with moving parts has wheels, yet no one knows exactly when the first wheel was invented or what it was used for. We do know, however, that they existed over 5,500 years ago in ancient Asia.

    The oldest known transport wheel was discovered in 2002 in Slovenia. It is over 5,100 years old. Evidence suggests that wheels for transport didn't become popular for a while, though. This could be because animals did a perfectly good job of carrying farming tools and humans around.

    But it could also be because of a difficult situation. While wheels need to roll on smooth surfaces, roads with smooth surfaces weren't going to be constructed until there was plenty of demand for them. Eventually, road surfaces did become smoother, but this difficult situation appeared again a few centuries later. There had been no important changes in wheel and vehicle design before the arrival of modem road design.

    In the mid-1700s, a Frenchman came up with a new design of road—a base layer (层) of large stones covered with a thin layer of smaller stones. A Scotsman improved on this design in the 1820s and a strong, lasting road surface became a reality. At around the same lime, metal hubs (the central part of a wheel) came into being, followed by the pneumatic tyre(充气轮胎) in 1846. Alloy wheels were invented in 1967, sixty years after the appearance of tarmacked roads (柏油路). As wheel design took off, vehicles got faster and faster.

    "No matter where you are or what time it is there's something going on at a Hard Rock Cafe. All over the world our cafes not only serve great food, but they serve up great music." Hard Rock Cafes around the world symbolize the timeless energy, originality and unifying (团结的) spirit that have helped to shape rock music over the last century.

    Founded by two Americans, the first Hard Rock Cafe (HRC) opened its doors to the public on June 14, 1971, in London. Today, HRC has become a global phenomenon with more than 180 cafes in different countries.

    HRC has also become the world's leading collector and exhibitor of rock ‘n' roll memorabilia. It all started when Eric Clapton, a regular at the first HRC, asked the staff if they could hang his guitar on the wall to mark his favourite stool (凳子) as "his spot". They did and one week later, a package from Pete Townshend arrived with a guitar and a note with the message, "Mine's as good as his! Love, Pete."

    Ever since then, Hard Rock Cafes have been collecting pieces of rock memorabilia and covering their walls with them. Their collection is rotated from restaurant to restaurant and provides the world's most comprehensive "visual history" of rock ‘n' roll. These treasures include an awe-inspiring collection of classic guitars and other instruments, posters, music, etc.

    Throughout its history, HRC has been governed by a special service philosophy: "Love All—Serve All." Since it was established, HRC has taken part in a wide variety of humane activities around the world. Following its idea of being more than just a restaurant, HRC tries to connect its business and its passion to make the earth a safer, healthier and better place to live.

    All in all, Hard Rock Cafe International is an entertainment company that continues to successfully expand the Hard Rock brand through countless music-related activities.

    Moscow city authorities have begun using comics (漫画) with characters from Russian fairy tales to explain to migrants (移民) how they should behave. They say a 100-page guide is needed to "keep a positive image" of the city and could help reduce "tensions" between natives and migrants. But critics have pointed out that foreign migrants and natives may be regarded as antagonists in the manual (手册).

    Russians and migrants have repeatedly flooded in Moscow recently. Many migrants from ex-Soviet republics in Central Asia, the Caucasus (高加索) and North Caucasus, arrive in Moscow every year, attracted by the capital's job opportunities and relatively high salaries. A significant number of them work in the Russian capital illegally.

    The new guide in Russian seeks to explain the "dos" and "don'ts" to migrants. They are urged not to cause trouble, by staring at women, or eating or talking loudly on the streets. They are also warned that the police may routinely (例行公事) stop them to check their documents.

    In the manual, Russia's famous "three warriors" are meant to represent the city's law enforcement agencies (执法机关), while Prince Yuri Dolgoruky (a historical character) is used for tours around Moscow. Meanwhile, Vasilisa the Wise and The Snow Maiden test the reader on Russia's language and history. A special section of the book explains the importance of following Moscow's strict residency and employment rules, stressing that migrants could otherwise be deported (驱逐出境) or banned from entry.

    The manual was written primarily for illegal migrants, Alexander Kalinin, who heads the group Support for Working Migrants in Moscow, told BBC Russian.

    "We want to raise their level of law awareness," he added.

    Migrant characters had initially (最初) been identified as representatives of different nationalities, but the book's authors later decided to drop this idea so as "not to offend anyone", said Mr. Kalinin.

    "The old conflict between Russian heroes and non-Slavic invaders is being revived," Yevgeny Varshaver, a migration expert told BBC Russian. He also suggested that the language used in the book would be "difficult" to understand for some migrants who were not native Russian speakers.

    Every year from March to October, Christian Moullec, also known as "Birdman," takes to the skies aboard his adapted light aircraft. However, the 58-year-old Frenchman's daily 30-minute flight is not just to enjoy the impressive views, but to guide flocks (鸟群) of lesser white-fronted geese (小白额雁) through safe migration paths which the birds can teach future generations.

    His deed began in 1995 when he noticed their declining population in the wilds of Lapland, Sweden. To prevent their numbers from dropping further, Moullec tried to get the threatened species to follow him along migration routes that would protect them from bird hunters.

    However, getting grown geese to follow his lead proved challenging. As young geese imitate and follow whomever they view as their parent, Moullec decided to raise the geese from birth.

    To help raise funds and awareness of his job to protect not just the geese but birds worldwide, Moullec often allows paying tourists to join him on the 30-minute-long flights aboard his aircraft. In addition to the trained birds flying alongside them, visitors, who come from as far as a 15-hour plane flight away, are treated to a variety of crane and geese species as well as breathtaking views of castles and cities.

    He often brings his camera along for the flights, capturing photos not just for their beauty, but for what they describe. Moullec believes the use of agricultural chemicals has done harm to wild European birds, with more than a third disappearing in the last 30 years. "It's a disaster," he said. "My beautiful images with flying birds should be used to tell this story."
