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).

    Cropping (修剪) an Image With the Snap Shot Program

    Welcome to the world of photo-editing!

    Cropping an image allows you to zero in on (对准，聚焦) just the portion that is important to your project. For example, you may want to insert an image of a covered train in a report but may not want to include the whole train. Cropping the image allows you to select only the small area you wish to retain (保留) and eliminate all other portions of the original picture.

    Option 1: Cropping by Placing the Image in a Shape

    Screen Shot 1

    Using one of Snap Shot's standard shapes as a photo-editing tool requires no special abilities to crop an image with a standard shape:

    a. Click Cropping & Orientation from the Effects menu.

    b. Click to select one of the six shapes to frame your image.

    c. Use the mouse pointer to draw a frame around the portion of the image you wish to retain. Re-size the frame by dragging the shape's sizing handles. When you are satisfied with the results, click Cut It.

    d. Snap Shot will automatically return to the project that is open. (You may also copy or cut the cropped image and paste it into another application.)

    Option 2: Freehand Cropping of an Image

    Screen Shot 2

    If you want to trace the shape of an object in order to crop out everything else, freehand cropping is the way to go. To crop an image freehand:

    a. Click Freehand Crop from the Cropping & Orientation option on the Effects menu.

    b. Using the mouse pointer, trace around the shape you want to crop. Be sure to completely enclose the image by ending at the same place you began outlining.

    c. Click Cut It. Snap Shot will automatically return to the project that is open.

    Robots are now being employed not just for dangerous tasks, such as discovering mines or rescuing people in disasters. They are also finding application as household helps and as nursing assistants. As increasing numbers of machines, equipped with the latest artificial intelligence, take on a growing variety of specialized and everyday tasks, the question of how people see them and behave towards them becomes ever more urgent.

    A team led by Sari Nijssen of Radboud University and Markus Paulus, Professor of Developmental Psychology at Ludwig-Maximilians-Universitaet (LMU), have carried out a study to determine the degree to which people show concern for robots and behave towards them based on moral principles.

    According to Sari Nijssen, the study set out to answer the following question:" Under what circumstances would adults be willing to sacrifice robots to save human lives?" The participants were faced with a hypothetical (假设的) moral dilemma: Would they be prepared to put a single person at risk in order to save a group of injured persons? In the situations presented the intended victim was either a human, a humanoid robot that had been humanized (人性化的) to various degrees or a robot that was clearly recognizable as a machine.

    The study suggested that the more the robot was humanized, the less likely participants were to sacrifice it. Situations that included vivid stories in which the robot was described as a merciful being or as a creature with its own understandings, experiences and thoughts, were more likely to stop the study participants from sacrificing it in the interests of anonymous (无名的) humans.

    "This result indicates that our study group attached a certain moral status to the robot," says Paulus. "One possible suggestion of this finding is that attempts to humanize robots should not go too far. Such efforts could come into conflict with their intended function—to be of help to us."

    When the tornado(龙卷风) passed, Lewis returned to her house after that awful night, and the Bible was the first thing she looked for. She had bought it 35 years earlier, at the start of her marriage. Like many folks, she'd used it to preserve the family's history: decades-old photos, newspaper obituaries(讣告) of loved ones, a handkerchief from her great-grandmother, even a piece of a scarf her uncle had brought back from the Korean War.

    The Bible was not where she'd last seen it, on top of an antique dresser in her bedroom. The only thing left was the solid pieces of marble that had been on the top of the furniture. After an hour of searching, one of the volunteers ran up to her and found the Bible while clearing through ruins. She had tears streaming down her cheeks. It had flown about ten feet from the dresser. Surprisingly, while many books had been destroyed beyond recognition, the Bible was still intact, even though it had sat in the rain for days. "It was a miracle," says Lewis.

    A few of the Bible's treasures did go missing. Yet ever so slowly, they, too, began reappearing in Lewis's life. Days after the Bible was found, volunteers discovered one of the newspaper obituaries outside the home. Two weeks later, a neighbor found another newspaper clipping(剪辑) by her house. "It was a shock," says Lewis.

    Now the Bible already has its well-deserved place of honor, on the dresser. She knows that while every good book tells stories of disastrous weather and unlikely survival, this one actually lived it.

Edward Ndiritu joined Lewa Wildlife Reserve in central Kenya in 1996 as a rhino monitor. Back then, illegal hunting had greatly reduced the country's black rhino population. Worried that they might become extinct, he worked his way up to lead Lewa's anti-hunting team. In 2015, his team's community-focused conservation method won him the first Wildlife Ranger Award from conservation charity Tusk.

He grew up in a village between Mount Kenya and the Aberdare Forest, which was once a wildlife route for migrating elephants and black rhinos. He saw them disappear gradually. He realized that hunting and the disruptive actions of the community were the reasons. The demand for rhino horn(角), which is very valuable in Asia, drives hunters. They are part of a big and rich crime network. There are people who help them by giving them equipment. In 2011 and 2012, Lewa had many difficulties. They lost rhinos. It was found that those involved in hunting were also linked to human smuggling(走私) and other illegal activities.

The hunting challenge has changed. Hunters now have networks, get information from the local community, and use technology like phones and motorbikes. Edward's team has adapted by using cameras, sensors, trackers, and a system that tells them when and where hunting might happen. They also work closely with the community, which is now the first 

line of defense. Lewa gives agricultural training, medical help, and business support to rural women. This makes locals more likely to report hunting before it happens.

To be a good forest guard, one needs to be honest, tough, and motivated. Edward now knows that making sure the forest guards are happy and well is very important. He is hopeful about wildlife conservation in Lewa. Funding is a problem, but organizations like Tusk are helping. Conservation is about people. Looking after those outside the reserve is necessary for the future of wildlife. Only when communities can live in harmony with the animals they see every day will there be a good future for wildlife.
