British chemist David Evans has become an overnight celebrity on Chinese social media. His chemistry experiments have attracted over 2 million followers in just a few months. Evans is a chemistry professor at Beijing University of Chemical Technology. The 60-year-old always wears a white lab coat, a pair of safety goggles (护目镜), and smiles often. Some web users say he looks just like "the Grandpa of KFC".

Evans has posted videos of various experiments. His most popular experiments have attracted millions of hits on video-sharing apps. Excited children's cheers and shouts can be heard in his videos. "I hope my experiments can arouse people's interest in science," he says.

Evans has been interested in China since childhood. In the early 1970s, before the reform and opening up, he viewed China as "a country full of mysteries". He first visited the Chinese mainland in 1987 to attend a chemistry conference in Nanjing, Jiangsu Province. He quit his job in the United Kingdom and moved to Beijing in 1996. Many of his friends thought he was crazy. But Evans said they just saw China's challenges but not its potential.

Since 2011, Evans has turned to the Internet to popularize science. He learned short-video apps are also popular in small cities and rural areas. And he realized this enables him to reach more students, who lack opportunities to perform fun experiments. But even a one-minute video requires a considerable amount of work. Still, he thinks it's worth it to fulfill his responsibility to popularize science.

His experiments always fill schools' lecture halls with laughter. Some viewers call him "a Harry Potter-like magician", but he disagrees." A magician never tells the secrets behind his tricks, but a scientist always gives an explanation." He sees himself as a teacher. He performs experiments to spread knowledge, inspire thinking, remove misunderstandings and show that science can create change. Evans says he looks forward to more "chemical reactions" with China.

    A new study, conducted by British company Mindlab International, has found that listening to music at work increases accuracy and speed, The Telegraph reported. Perhaps, some parents disagree with this idea, saying, "Switch off the music and concentrate!" Well, if that's the case with your parents, you might now be able to convince them that you have science on your side.

    The company gave 26 participants a series of different tasks for five days in a row, including spell checking, mathematical word problems, data entry, and abstract reasoning. The participants completed these tasks while listening to music or no music at all.

    The results showed that while music was playing, 88% of participants produced their most accurate test results and 81% completed their fastest work. David Lewis, chairman of Mindlab International, told The Telegraph, "Music is a very powerful management tool if you want to increase not only the efficiency of your workforce but also their emotional state... they are going to become more positive about the work."

    However, you may have a list of your favorite songs, but not all kinds of music match all homework. For maths or other subjects involving numbers or attention to detail, you should listen to classical music, the study found. In the study, pop music enabled participants to complete their tasks 58% faster than when listening to no music at all. If you are reviewing your English writing, pop music is the best choice, as it is the best kind for spell checking. It cut mistakes by 14%, compared to listening to no music. After finishing your homework, do you often take time to check your answers? Maybe, some dance music is suitable for you.

    More than 135,000 UK drinkers will die from cancer caused by alcohol(酒精)by the year 2035, researchers say. A study by Sheffield University and Cancer Research UK shows that alcohol will cost the NHS (National Health Service)£53 billion over the next ten years including £2 billion on cancer.

    Although alcohol is known to cause many types of cancer including breast and throat, most people don't realize the relation between alcohol and cancer. A survey of 2,100 Britons by the researchers earlier this year found nine in ten did not connect drinking with cancer. The researchers used a computer model to work out the numbers of alcohol-related cancer deaths, hospital admissions(入院)and total costs to NHS over the next 20 years.

    The study shows that a fifth of men and 1 in 10 women have alcohol every day—many of these are middle-aged and middle class. Researchers are very worried about this group as they believe cancer may be caused by drinking over long periods. The study shows that even if the cost stays as it is, alcohol-related cancer deaths will rise from 6,299 in 2015 to 7,097 in 2034. Alcohol will lead to 891,299 hospital admissions, up from 802,118 in 2015, and 65,005 will be caused by cancer.

    Earlier this year Chief Medical Officer Dame Sally Davies studied carefully the alcohol guidance(指导)for the first time in thirty years. She told people there was no safe level of drinking and advised them to drink no more than 14 units a week. But researchers say this guidance isn't enough and want the government to increase a little price per unit of alcohol.

My love for libraries blossomed when I joined the public library. From the age of 8 I was allowed to walk from my home to the downtown library, housed above the police station. Once the librarian gave me my first membership card, I could enjoy a range of books, which started with Little House in the Big Woods. I was addicted instantly, and this love of libraries and reading would change my life, allowing me to one day create a safe space for high-school kids, too.

By the time I was in high school, I could read the authors that we were studying in class, including Charles Dickens, Mark Twain and Emily Bronte. During the summer months, I got caught up in Gone with the Wind.

When I studied English literature at university, I thought it was time to build my own library. For the next 40 years, I continued to collect books. Until one day, I realized that all my books had become a part of the house, like wallpaper.

Toward the end of my teaching career, I became a teacher-librarian at my old high school, where I had first learned English literature. This position enabled me to regain my love and appreciation for libraries. I had a generous budget for my classes, so I searched for novels that would interest my teenage audience and hopefully spark a love of books. Fantasy, science-fiction, graphic novels -I bought almost any type of books that my students wanted to read. I bought sofas and comfortable chairs, turning the library into a safe public space, for everyone.

In doing so, I realized that the library isn't just a place to do research. They are, in fact, places that offer an opportunity to connect with the past, present and future. All that is required is a tiny bit of curiosity. Libraries are places that should be full of life. They help us adjust to the world, and their doors must be kept open to everyone for free!
