TIANJIN, Nov.23 (Xinhua)- Chinese scientists have signed a deal to establish a commercial animal cloning center in the northern port city of Tianjin, making the controversial science closer to mainstream acceptance.

    The plant in the Tianjin Economic and Technological Development Area (TEDA), a government-sponsored business development park, will clone animals including sniffer and pet dogs, beef cattle and racehorses. Its main building is already under construction and due to be put to use in the near future, said a spokesman on Monday.

    With an investment of 200 million yuan, the center will be jointly built by Sinica, Peking University's Institute of Molecular Medicine, the Tianjin International Joint Academy of Biomedicine, and the Republic of Korea's Sooam Biotech Research Foundation.

    It will produce 100,000 cattle embryos a year initially, eventually increasing to 1 million, said Xu Xiaochun, board chairman of Boyalife Group, based in Wuxi. Chinese farmers are struggling to produce enough beef cattle to meet market demand, Xu said. The center, the largest ever worldwide, will also include a gene storage area and a museum, he added.

    Scientists have cloned mice, cattle and other animals since the world's first cloned sheep, Dolly, was born on July 5,1996 iii Britain. Since 2000, Chinese scientists have cloned sheep, cattle and pigs. China's first commercial cloning company was established in September 2014 in Shandong with the birth of three pure-blooded Tibetan mastiff puppies.

    Before this, cloning in China was limited to scientific research. More and more companies have shown interest in investing in the technology for commercial use, especially animal husbandry (饲养).

Access to Residential Rooms

    Students are provided with a combination (组合密码) for their room door locks upon check-in. Do not share your room door lock combination with anyone. The Office of Residence Life may change the door lock combination at any time at the expense of the resident if it is found that the student has shared the combination with others. The fee is $25 to change a room combination.

Cooking Policy

    Students living in buildings that have kitchens are only permitted to cook in the kitchen. Students must clean up after cooking. This is not the responsibility of housekeeping staff.

    Time flies, but the tracks of time remain in books and museums. This is what made a recent tragedy in Brazil even more terrible.

    On Sept.2, a big fire ripped through the National Museum of Brazil.“ Two hundred years of work, research and knowledge were lost,” Brazilian President Michel Temer wrote on Twitter after the fire. “It's a sad day for all Brazilians.”

    Most of the 20 million pieces of history are believed to have been destroyed. Only as little as 10 percent of the collection may have survived, Time reported. Among all the items, there were Egyptian mummies, the bones of uniquely Brazilian creatures such as the long－necked dinosaur Maxakalisaurus, and an 11,500－year－old skull called Luzia, which was considered one of South America's oldest human fossils.

    Besides these, Brazil's indigenous(本土的，土著的) knowledge also suffered. The museum housed world－famous collections of indigenous objects, as well as many audio recordings of local languages from all over Brazil. Some of these recordings, now lost, were of languages that are no longer spoken.

    “The tragedy this Sunday is a sort of national suicide, a crime against our past and future generations,” Bernard Mello Franco, one of Brazil's best－known columnists, wrote on the O Globo newspaper site.

    The cause of the fire is still unknown, as BBC News reported on Sept. 3. After the fire burned out, crowds protested outside the museum to show their anger at the loss of the irreplaceable items of historical value.

    According to Emilio Bruna, an ecologist at the University of Florida, museums are living, breathing stores of who we are and where we've come from, and the world around us.

    Just as underwater grass floats on the surface if it loses its roots, a nation is lost without its memories. The fire at the National Museum of Brazil teaches the world an important lesson: We should never neglect history.

    A Russian spacecraft traveling to the International Space Station Thursday had to make an emergency landing when a rocket engine failed to fire. It was the latest in a recent series of failures for the Russian space program, which is also used by the U.S. to carry its astronauts to the station.

    United States astronaut Nick Hague and Russian astronaut Alexei Ovchinin landed safely about 20 kilometers from Dzhezkazgan in Kazakhstan. The city is about 450 kilometers from the Russia's Baikonur space center, which Russia operates through an agreement with the Republic of Kazakhstan.

    Both the U.S. space agency NASA and Russia's Roscosmos reported that the two were quickly recovered from the landing area by rescue crews. A spokesman for Russian President Vladimir Putin said, "Thank God the crew is alive" after they had landed safely.

    About two minutes after launching, the three-stage Soyuz booster rocket suffered an unspecified failure of its second stage. Russia's TASS news agency said the capsule carrying the two men separated from the troubled rocket safely. This caused the capsule to drop very sharply into the Earth's atmosphere. Parachutes（降落伞）helped slow the returning capsule. Search and rescue teams were sent to recover the crew.

    Russia's RIA news agency reported that Russia has immediately put off all manned space launches after the failure. Roscosmos head Dmitry Rogozin said he had ordered a state commission to carry out an investigation into what went wrong. He said Russia will share all relevant information with the U.S.

    The TASS news agency said that the ISS crew has enough supplies and that the failed launch will not affect operations.

    The U.S. and other nations have depended on Russia to carry astronauts to the ISS since the retirement of the Space Shuttle program in 2011. In coming years, American aerospace companies SpaceX, with its Dragon 2, and Boeing, with its Starliner, are expected to return to space.

    Before the 1830s most newspapers were sold through annual subscriptions in America, usually $8 to S10 a year. Today $8 or $10 seems a small amount of money, but at that time these amounts were forbidding to most citizens. Accordingly, newspapers were read almost only by rich people in politics or the trades. In addition, most newspapers had little in them that would appeal to a mass audience. They were dull and visually forbidding. But the revolution that was taking place in the 1830s would change all that.

    The trend, then, was toward the "penny paper" ­ a term referring to papers made widely available to the public. It meant any inexpensive newspaper; perhaps more importantly it meant newspapers that could be bought in single copies on the street.

      This development did not take place overnight. It had been possible (but not easy) to buy single copies of newspapers before 1830, but this usually meant the reader had to go down to the printer's office to purchase a copy. Street sales were almost unknown. However, within a few years, street sales of newspapers would be commonplace in eastern cities, At first the price of single copies was seldom a penny ­ usually two or three cents was charged ­ and some of the older well-known papers charged five or six cents. But the phrase "penny paper" caught the public's fancy, and soon there would be papers that did indeed sell for only a penny.

    This new trend of newspapers for "the man on the street" did not begin well. Some of the early ventures were immediate failures. Publishers already in business, people who were owners of successful papers, had little desire to change the tradition. It took a few youthful and daring businessmen to get the ball rolling.

    The Secretary-General of the U.N. has always been chosen in private meetings. But for the first time in its 70-year history, part of the selection process is taking place in public.

    At least eight countries have announced their candidates (候选人) for the position, among whom are women, including Irina Bukova from Bulgaria, Susana Malcorra from Argentina and Helen Clark from New Zealand. 56 countries says the next U.N. chief should be a woman. There have been eight U.N. chiefs, none of whom was a woman.

    All member states were permitted to ask the candidates questions during two hour-long meetings last week in the U.N. General Assembly (联合国大会). The candidates were also asked some of the 1,000 questions written by people on social media.

    They were asked questions about development, how they would improve efforts to create peace and how they would protect human rights.

    The U.N. Security Council will examine the candidates' backgrounds. Then the 15 members will vote secretly until one person is chosen. The General Assembly will then vote on whether to accept the choice.

    Britain, China, France, Russia and the United States are the five permanent members of the Security Council. Experts say they are likely to have more influence on who will be the new secretary-general than the 10 non-permanent nations on the council.

    The Security Council will begin to discuss who will be named the next secretary-general in July. A new secretary-general may not be confirmed until as late as November.

    The U.N. has a tradition of choosing its new leader from a part of the world different from its current leader. U.N. Secretary-General Ban Ki-moon is from Asia. The previous U.N. chief was Kofi Annan, who was from Africa.

    Dan Thomas is a spokesman for the president of the General Assembly. He says there is no rule that says where a new secretary-general must come from. But most observers say the new U.N. chief will not be from Asia or Africa.
