A drug that is used to treat serious bleeding could save thousands of lives of mothers giving birth. A world test of the drug found it reduced (降低) the risk of bleeding deaths during childbirth by nearly one third. The study included 20,000 women in 21 countries, mainly in Africa and Asia. The test was carried out by London School of Hygiene and Tropical Medicine. The drug is called tranexamic acid (凝血酸). It is low-cost and researchers said it does not cause serious side effects (副作用) for mothers or babies.

    The drug is used to treat mothers for serious bleeding during childbirth. Postpartum hemorrhage (产后出血) is the main cause of mothers' death around the world, according to the World Health Organization.

    Haleema Shakur is the project director for the test. She said though medical condition is improved in many countries, serious bleeding after childbirth remains a big problem in some parts of the world. “It's one of the biggest killers of mothers. In Africa and Asia, about 10% of women will end up with serious bleeding.” The drug works after a mother gives birth.

    Shakur said the best results were reported when the drug was given to women as soon as possible after childbirth. “The earlier you give it — within the first three hours after giving birth — the better the result is.”

    The next step will be to provide training for doctors and nurses on how to use it and then to find where the drug is needed. During the test, women were given the drug in a hospital. But researchers are looking for easier ways to use the drug so it can be more widely used in small clinics and the countryside.

    When asked how technology might improve the lives of people with vision impairments (视力障碍), Joann Becker presented a misleadingly simple challenge. “Well,” the vision impairments tech specialist recalls saying. “I'd like to be able to find my bus slop through Be My Eyes”.

    Be My Eyes, which went live in 2015, establishes a direct video connection between visually impaired users and sighted volunteers. The assumption is simple: Many people who are blind don't need any actual assistance in completing their daily tasks, but merely need a little help.

    A sighted volunteer might be asked to help identify which of two cans contains tomatoes. In this case, the visually impaired user can cook a meal just fine on his/her own-all he/she needs is a quick confirmation that he/she has the correct can. The model appears to be working; more than 540,000 volunteers and nearly 40,000 people with low vision are registered on the app.

    “An elderly woman can now help a visually impaired technician set up his computer,” says founder Hans Wiberg, who has very low vision. “She doesn't need to know a thing about computers. She only needs to read what is presented on the screen. Then he can do the rest.”

    Early assistive technology centered on dedicated devices (专用设备), because of the niche market (缝隙市场), which sold for hundreds or even thousands of dollars. But the smartphone, multipurpose and near-universal, has completely changed the economy of scale.

    “There are larger market forces driving high-powered computation, high-quality engineering and high-quality battery management in the smartphone market than those in a specialty product,” says Aaron Steinfeld, a research professor at the Robotics Institute at Carnegie Mellon University.

    “The reality is, most sighted people don't know somebody who is blind.” Becker says. “They think the solutions that a blind person needs arc far more expansive, it turns out, they need to be. I think these apps are enabling sighted people to see that blind people just need some simple clues to help them do any number of things in their lives.”

    One of the “Home Counties” to the north and west of London, Buckinghamshire is known for the rolling Chiltern Hills, its pretty villages, and the much-loved children's author Roald Dahl.

    The writer who penned Charlie and the Chocolate Factory, The Witches, Matilda and The Big Friendly Giant is the i9nspiration for the Whizzfizzing Festival – which will transform the market-town of Aylesbury into all kinds of music, colour and fun on Saturday, 1 July.

    Formerly known as The Roald Dahl Festival, this year's event will celebrate a broad range of children's films and bring to life some of its best-loved characters – from Alice in Wonderland and the Gruffala to The Big Friendly Giant and Harry Potter.

    Things to see and do

    The fun and festivals start at 11 a.m. with a colourful children's parade. More than 650 local school children and teachers, many in fancy dress, will march through the town carrying giant carnival puppets（木偶）, with thousands of audiences lining the streets to watch.

    The parade will be followed with a range of child-friendly activities and workshops held in venues across the town.

    Don't be late for the Mad Hatters Tea Party in the Bucks County Museum, catch a splendid screening of a Roald Dahl movie in the Old        Court House, and watch leading children's authors, including Julian Clary, give readings in the Market Square.

    CBeebies' children's chef Katy Ashworth will once again be cooking up a storm with her inter-active

    Concoction Kitchen, located outside Hale Leys Shopping Centre. Little chefs will have lots of opportunities to get involved with preparing, cooking – and best of all, tasting – Katy's fabulous recipes.

    With hands-on arts and crafts workshops, storytelling sessions, live music, a fancy dress competition, street theatre and more, there is something for everyone.

    China is fondly remembering one of its most famous radio voices, a man whose vivid storytelling was a comfort to millions of people, from commuters stuck in traffic to restless teens struggling to sleep. Shan Tianfang, was a leading performer of the traditional Chinese art form pingshu, which translates as "storytelling".

    Pingshu dates from the Song Dynasty (AD960-1279) when performers would entertain villagers by telling stories in a particularly emotive style. It remains particularly popular in north-eastern China. Performers wear traditional dress and use very basic props - often a folded fan and a gavel. Pingshu is sometimes performed in tea houses and small theatres, but many Chinese associate the art form with radio. And in a country where sleeping problems are commonplace, pingshu is still popular as a way of helping people to wind down at bedtime.

    Shan Tianfang was born in 1934 in Yingkou, in north-eastern Liaoning province. His family introduced him to folk arts from a young age and he began learning pingshu when he was 19. He became known in Liaoning for his work on stage and in local teahouses during the 1950s and 1960s, and performed in an art troupe around the region. From 1966-1976, Shan, along with other pingshu performers like Yuan Kuocheng, was forced to stop work. During the 1980s.Shan made the transition (转型) to state-run radio, and his captivating storytelling became comfort listening for people across the country. By the 1990s, Shan had become a well-known face on state TV, even performing in the annual Spring Festival Gala show. He has died aged 84 following a long illness.

    Shan performed over 12,000 stories on TV and radio. His stories attracted people of all ages. One of his most acclaimed performances is of the Heroes in the Sui and Tang Dynasties. He gave countless performances of the “Four Classic Novels” (Romance of the Three Kingdoms, Journey to the West, Dream of the Red Chamber and Water Margin) and also helped to bring lesser-known classical Chinese literature to new audiences.

    He was able to use the medium to entrance his audience and in the process he helped to popularise classical Chinese literature. As film director Zhang Jizhong told the Global Times newspaper: “He could describe a scene and a character extremely vividly. He once had a long talk with me about adapting the heroic stories he told into films or television shows to help promote Chinese classics and traditional culture.”

    But in his later years, the growth of online and digital media exposed the challenges of keeping his art form alive. Shan turned his efforts towards writing books and opening performance schools to teach pingshu to young people. They included the Shan Tianfang Culture and Media Academy in Beijing, a Shan Tianfang teahouse and “storytelling base” in Anshan in Liaoning province. Meanwhile, modern productions of pingshu reference (引用，参照) contemporary  (现代的) culture to draw in new performers and audiences. Performers like Guo Heming have emerged, putting a modern spin on pingshu by adapting popular works, including the Harry Potter stories.

    Although he wasn't particularly active on social media, he amassed more than one million fans on the Sina Weibo platform.

A memorial was held for him on 15 September but millions of Chinese will miss his voice.

    The UNESCO has recognized the Chinese art of paper cutting on its Intangible Cultural Heritage List. But paper cutting is at the risk of disappearing.

    Voyo Woo, a Chinese immigrant, who loves paper cutting, worked hard to celebrate the ancient art form. With a keen interest in paper cutting, Ms Woo held a paper cutting exhibition at a shopping center near Washington. "I really love it. I get so much fun by doing it. So I'm just kind of hoping that more people will learn about this art which is about to disappear. I think it's time to take action. So I held it."

    Voyo Woo began to study paper cutting when she was a 14-year-old girl in southeastern China. Voyo Woo's teacher gave her extra training after class because Voyo Woo discovered a special love for it. Later, her beautiful paper cuttings won second prize in a national painting competition. "Paper is the easiest material that you can find. You can just turn it into beautiful art. I think it is like magic to me."

    Ms Woo came to the US after she finished college in 2008. She has been invited to show the art at a wide collection of events. She also has shown her skill and works at famous museums like the Smithsonian Institution's Freer and Sackler art galleries in Washington.

    "I saw so many people coming to me and asking me. They were amazed. I think it's important to introduce the art form to American people or anyone who is interested."

    Ms Woo placed examples of her art around her as she displayed paper cutting at the shopping center. Ann Russ, a shopper, was attracted by the nature of the work. She said it put her at ease. "I like to know about Chinese art, specifically because it's almost relaxing to put that much effort into it," Russ said.

    American and British people both speak English of course. But sometimes it does not seem like the same language. In fact, there are some important differences between British English and American English.

    First of all, they sound very different. Often, Americans don't say each word separately. They say several words together. Americans may say "I dunno" instead of "I don't know". Or they may say "Whaddaya say?" instead of "What do you say?" However, the British are more careful in their speech. They usually say all the words and keep them separate.

    Sound is not the only difference between British English and American English. Words sometimes have different meanings too. Some American words are never used in England. The same thing is true of some British words in America. For example, the vocabulary for cars and driving is very different. Americans drive trucks, but in England people drive lorries.

    Many expressions are also different in the two countries. In England，if you are going to telephone your friends, you "phone them up". In America, you "give them a call". When you are saying goodbye in England you might say "Cheerio!" In America you might say "See you later."

    There're also some differences in grammar. For example, Americans usually use the helping verb "do" when they ask a question. They say "Do you have a storybook?" But the British often leave out the helping verb. They say "Have you a storybook?"

    All these differences can be confusing if you are learning English. But most languages are like this. Languages change over time. When people live in separate places, the languages change in different ways. This is what has happened to English. It can also happen to other languages, such as French. Many people in Canada speak French, but their French is very different from the French of France.
