China became the first country to clone a monkey using non-reproductive cells, scientists said on Thursday. By December 2017 , the Chinese Academy of Sciences had created two clone macaques(猕猴) named“Zhong Zhong” and “Hua Hua”by nuclear transferring of body cells—any cell in the organism other than reproductive cells. This was the similar technology used to create the famous clone sheep Dolly in 1996.

    Telra, a monkey born in 1999 , is the world's first ever-cloned monkey, but it was done using a simpler method called embryo splitting(胚胎分裂)，and cannot be genetically modified to suit experimental needs, said Pu Muming, a leading researcher at the Chinese Academy of Sciences. Cloning a monkey using body cells has been a world-class challenge because it is a primate(灵长类)that shares its genetic makeup, therefore all of its complexity, with humans, he said.

    For drug and other lab tests, scientists have to purchase monkeys from all over the world, which is costly, bad for the environment and produces inaccurate results because each monkey might have different genes, Pu said.

    By cloning monkey using body cells, we can mass reproduce a large number of genetically identical monkeys in a short amount of time, and we can even change their genes to suit our needs, he added. “This can save time, cut down experiment costs, and produce more accurate results, leading to more effective medicine.”

    Sun Qiang, director of the non-human primate research facility at the institute, said most of the drug trials are currently done on lab mice. However, drugs that work on mice might not work or even have severe side effects on humans because the two species are so different.

    Monkeys and humans are both primates, so they are much closely related and testing on monkeys is supposed to be as effective as testing on humans. This achievement will help China lead the world research in an international science project related to study of primate brains.

    In France, franglais（英式法语）was seen as a national threat. Just as we took in thousands of French words in the Middle Ages, French speakers and writers today are taking in thousands of English and American expressions. By 1994, so many English words had made their way to French that the French government passed a law forbidding the use of English words where good French words existed.

    But the latest edition of the Academy francaise dictionary did admit about 6,000 new words to the French language, including, for the first time, a number of franglais words and expressions.

    However, this sort of thing is not just limited to traditional English – French Competition. Norway and Brazil have recently taken similar measures to keep English out.

    As English spreads around the globe, it has developed rich varieties. English has been spoken in Singapore since the early 19^th century, but after independence from Britain, Singapore went a step further and English was made the official language of business and government. But the day −to–day English that the people of Singapore actually speak is a far cry from the official English that the government wants them to learn. It has become an expressive dialect called “Singlish”, full of vocabulary and grammar borrowed from the Singapores' native languages.

    And this may be the irony（讽刺）of the global spread of English. The more widely it's spoken, the more it may change into local dialects, which are not easily intelligible. People will make English their own and, in doing so, will make it something else. This has happened before to Latin which broke into French, Italian, Spanish, Portuguese, and Romanian. But English has always welcomed variety and change, and it still does.

    Today, we are constantly bombarded with media reports about research on the right diet to follow to help us maintain a healthy lifestyle or lose weight—but it's hard to know which one to pick and, once chosen, it's harder still to stick to it. And now there's another choice to get our teeth into.

    A flexitarian(弹性素食者)diet involves eating plant—based foods and only occasionally eating meat and fish. This eating style allows you to supplement some ingredients that you wouldn't get in a stricter vegan(素食主义者)diet—another trend growing in popularity. And like veganism, flexitarianism isn't about eating carefully to help you lose a few pounds—it's something people choose for ethical reasons, to help the planet. And a study into the global food system and how it affects the climate, has found that eating mainly plant-based foods is one of three key steps towards a sustainable future for all by 2050.

    This research found that food waste will need to be halved and farming practices will also have to improve to achieve this. But without a single solution, a combined approach is needed. Dr Marco Springmann from the University of Oxford was one of the lead authors of the report. He told the BBC “We really found that a combination of measures would be needed to stay within environmental limits and those include changes towards healthier more plant—based diets.”

    But whereas vegans think it's wrong for animals to be killed for food, flexitarians believe eating meat once in a while is acceptable. And Dr Springmann agrees—as long as we “treat it as a luxury, it's probably OK but you shouldn't have more than one serving of red meat, which includes beef and pork, per week.” And here's another fact to digest: If we moved to this type of diet, the study found that greenhouse gas emissions from agriculture would be cut by more than half.

    Each year, hundreds of thousands of wild animals around the world are killed in trophy hunting—the organized shooting of animals for pleasure. The hunters then bring parts of the animal home with them as their "trophy" to remember the hunting.

    Trophy hunters pay big money to kill animals. Some of the money goes to helping wildlife protection. Trophy hunting also attracts business, which encourages people to preserve land and breed(饲养) animals that would otherwise be endangered. Cathy Dean, head of the Save the Rhino Charity, says that at the start of the 1900s there were only 50–100 southern white rhinos. Now, there are around 18,000. This is partly because some of them were raised specially for trophy hunting.

    But things don't usually go on one way. According to WWF, elephant populations have fallen from 1.3 million to just over 400,000 since the 1980s. Over the same period, hunters from around the world have taken home more than 100,000 African elephant trophies. Trophy hunting is not illegal(非法的) but unfair on the animals. In 2015, Cecil the lion was shot by a US trophy hunter. Cecil was a beloved lion in Zimbabwe, Africa. Cecil was lured with bait(诱饵), shot with an arrow and struggled in blood for more than ten hours before his hunters tracked and finished killing him. His son, Xanda, met a similar fate two years later.

    Cecil's death caused worldwide outrage and protests(反抗) against trophy hunting. Countries including Australia, France and the Netherlands banned(禁止) the import of lion trophies—they stop hunters from being allowed to bring home parts of the animal they kill. They believe that people will stop trophy hunting because the activity might lose its attraction if hunters can't bring their trophies home.

    The UK Government said that it would consider a ban on trophy-hunting imports by 2017, but no action had been taken. In April 2019, a letter by protesters against trophy hunting was sent to the UK government asking to ban trophy-hunting imports. On 7 May, the official in charge of the environment, Michael Gove, said that the UK would not ban the imports for the time being. This left the world in a state of a shock. Hopefully the UK will place a ban on trophy-hunting imports, which would be an important message and inspire others to treat animals better. We're waiting for the day to come.

    Robots that can chat, find misplaced glasses, draw airplanes and play with your children are attracting thousands of visitors during an expo in Tokyo as Japan adapts to changes in society.

    Robots, such as the sound-sensitive Chapit, answer simple questions and even joke with people to help the solitary fight loneliness and stay alert (机警的) in old age. "Many old people in Japan live alone and have no one to talk to," said Kazuya Kitamura, a representative of the expo organizer. "Communication robots stay together with old people and don't mind listening to the same stories over and over again."

    While Chapit, a relatively simple robot, managed to attract a partner, many researchers, such as Kiyoshi Matsumoto, a professor at the University of Tokyo, struggle to attract sponsors for more expensive projects.

    Matsumoto's "Personal Mobility Robot", equipped with four cameras and a sensor to recognize the user's centre of gravity, is designed to help the elderly move around without pressing buttons as in traditional wheelchairs.

    The robot can also help find misplaced glasses by recognizing them with a sensor. "We have developed a robot that can assist many people, but because of the high cost, we still haven't found a sponsor," said Matsumoto, who added that the cost of the machine, if produced in large quantities, would be comparable to that of a small car. "In the current economic environment there are few companies willing to invest (投资) in such a costly project," he said.

    Other robots, such as the award-winning "DiGRO", can support busy parents who have little time to play with their children. The robot can use the Internet to find a simple image and then draw pictures, looking after children while parents work.

    Japan is one of the world's fastest-aging countries and the government predicts that by 2050 the population of people over 65 will reach 40 percent.

From a young age, Michael Platt loved two things: the Rev. Martin Luther King, Jr. and cupcakes. He imagined ways he too could fight for justice. He memorized figures about income inequality and childhood hunger. But he also spent afternoons at his home computer, amazed by YouTube bakers who made perfect cupcakes.

When his parents gave him a pair of Toms shoes for Christmas three years ago, Michael saw a way to connect his twin passions. At age 11, he founded a bakery that operates on the Toms one-for-one model: For every cupcake, cake or cookie that Michael sells, he donates another to the homeless and hungry. Twice a month, he heads to locations to pass out goodies. Michael, now 13, said he especially enjoys handing out cupcakes to kids.

"I know I like cupcakes, but also cupcakes are part of a child's childhood so they should get them," said Michael, noting that he always eats one with whippedicing (打发的糖霜) on his birthday.

Michael calls his baking business Michaels Desserts. He left out the apostrophe (撇号) as a reminder that he is baking for others, not himself. "I always wanted to have a purpose for what I do." he said. "It's all about helping people— not just having a purpose for yourself, but thinking about, 'How does this touch other things? "

When he started the bakery, he knew that he wanted his business to do more than make money. That's why the intention of Michaels Desserts is fighting hunger and giving back, which Michael accomplishes through his giveaways. Michael hopes his cupcakes inspire others to work for social equality.

Sometimes, Michael admits, he grows tired of being in the kitchen. Then he remembers the homeless boy he met once while handing out cupcakes. A couple of days afterward, the boy's father messaged Michael on Facebook to say that his son, encouraged by Michael's example, now desired to become a baker.

"That inspired me," Michael said. He smiled and looked down.
