1990 was an important year in world events. In February, Nelson Mandela was set free after 27 years in prison. In October, East and West Germany became one country again. Then at the end of 1990, the World Wide Web was born. For this final event we have one man to thank. Tim Berners-Lee, the father of the Web.

    Berners-Lee was born on June 8, 1955 in London, England. His parents, both computer designers, encouraged him to think and work creatively as he grew up. He was an excellent student and naturally took an interest in computers and science.

    After graduating from Oxford University, Tim went to work at a science research centre in Switzerland. There he developed some of the different systems（系统）that would later become the Web. The first was HTML, the computer language used to make web pages. The second was an address system that let computers anywhere find each other and send and receive information. In 1990 he put them together to make the first Internet browser（浏览器）.

    Tim knew that the more people used the Web, the more useful it would be. He wasn't interested in money but knowledge, so he gave out his invention for free to anyone who was interested. Many were interested an the growth of the Internet began.

    Today Tim works as a professor at the MIT in America, studying new ways to use the Web. He has received many awards from governments and organizations for his efforts. He is still not very interested in money. That is why he is so liked by his students and workmates. It may also be one of the reasons that few people outside the world of technology know his name.

    They aren't great artists like Leonardo da Vinci or Vincent van Gogh, but their paintings are just as popular on Chinese social media, with millions of Chinese people willing to pay for them.

The 36 works were painted by ordinary Chinese people who live with autism (自闭症) or cerebral palsy (脑瘫), aged from their early teens to late thirties. They all studied art at World of Art Brut Culture (WABC), which is a Shanghai-based non-profit organization (非赢利组织) for art education. The project was started by WABC and supported by the Tencent Charitable Foundation. Users could buy a digital copy of each painting by donating (捐赠) 1 yuan or more. By Aug 29, donations totaled more than 15 million yuan, with about 5.8 million people participating (参与).

    “The paintings by these autistic kids and adults are beautiful: the style is similar to that of the Dutch artist Van Gogh. I'm really impressed by their talent,” Feng Li, a customer service officer in Shanghai, told the South China Morning Post.

    However, the popular campaign also led to certain questions.

    Li Laoxi, an experienced special education teacher in Hangzhou, said that based on his experience, people with autism could only draw a few lines or fill in colors under the guidance of their trainers. “Maybe there are some geniuses out there, but I've never met them”. Others questioned where the money would go, as the donations went to WABC instead of the painters. In response to these concerns, Miao Shiming, founder of WABC, said the money would be used to employ art teachers, buy supplies, and rent facilities. Meanwhile, Tencent said that all donation information would be open to the public.

Dear Miss Hanff,

    You will be glad to know that the two boxes of eggs and the tins of tongue have all arrived safely and once again we all wish to thank you most sincerely for your extreme generosity. Mr. Martin, one of the older members of our staff, has been on the sick list for some time and we therefore let him have the lion's share of the eggs, one whole boxful in fact, and of course he was delighted to get them. The tins of tongue look very inviting and will be a welcome addition to our larders (食物橱) and in my case will be put on one side for a special occasion.

    I enquired at all the local music shops but was unable to get the Messiah or Bach's St. Matthew Passion in stiff covers in clean, secondhand copies, and then I found they were available from the publisher in new editions. Their prices seemed a bit high, but I thought I had better get them and they have been sent by Book Post a few days ago, so should arrive any day now. Our invoice, total $4.20, is enclosed with the books.

    We are sending you a little gift for Christmas. We do hope you will not have to pay any duty on it. We will mark it "Christmas Gift" and keep our fingers crossed. Anyway, we hope you will like it and accept it with our sincere best wishes for Christmas and the coming year.

    My name is certainly not of Welsh origin. As it is pronounced to rhyme with the French word "Noel", I think there may be a possibility that it originated in France.

Yours sincerely,

Frank Doel

    It was dinner time for the Rangers, a group of mostly Indigenous (本地的) Australians who had spent a long day cleaning up the polluted beaches of the continent's northern coast. Soon they would be eating freshly caught fish and seafood cooked under the stars on an open fire, as their ancestors did.

    The Rangers are of more than 100 Indigenous groups spread across Australia who have taken on the job of protecting the land of their forefathers. In Arnhem Land, they are the protectors of 3,300 square miles of land and sea. They comb the beaches by hand, picking up as much rubbish as possible. The task is very difficult as each day it delivers waves of new rubbish.

    For the Rangers, cleaning the beaches is more than a vacation. For a people whose culture is strongly tied to the land, protecting the environment is equal to preserving their history.

    However, colonization forcefully broke their connection to the land generations ago. Indigenous people were displaced and their cultural practices outlawed. Tens of thousands of years of traditional land management ended, and as a result many parts of the country now face serious disasters from invasive plant and animal species, bush fires and land mismanagement.

    In recent years, the government has restored more than 20 percent of Australia's land to Indigenous owners. Since 2007, the Indigenous Rangers Organizations have been at work protecting this land.

    Luck, one of the few non-Indigenous employees working with the Rangers, said the combination of old and new techniques and an appreciation for the culture of Indigenous workers has been critical to the program's success.

    "You are working with staff who see the world different to you, so there is a much higher focus on the cultural aspects of work and life," he said.

    "Being a ranger is a source of confidence. You feel strong," said Terence, a senior ranger. "Here we still live on the land. The culture is still alive."

    Artificial intelligence (AI) is practically everywhere today. There are so many products out there which use AI. Some are being developed, some are already in use, and some failed and are being improved, so it's very difficult to name a few of them and regard them as the best.

Humans aren't the only animals that move to music. Parrots have been known to do it. And now rats have been observed bopping their heads in time with the tunes of Mozart, Lady Gaga, Michael Jackson and others, according to a new paper from the University of Tokyo. What's more, the rats seems to respond to the same beats that get humans' feet tapping (轻跺). 

The researchers played a sonata by Mozart for lab rats at different variations of the original speed. Wireless sensors on the rats' bodies tracked their movements. Meanwhile, 20 human participants were involved and listened to the same music through headphones equipped with motion sensors. 

It was observed that the rats' head movements were the most obvious when the music played at its normal speed, which was around 132bpm (beats per minute). The same was true for human participants. The researchers then changed to some pop songs such as Lady Gaga's "Born This Way" and Michael Jackson's "Beat It". As with Mozart's, rats moved their heads along the rhythm of pop songs, similar to how people do, at about 120 to 140bpm. 

The study showed that both rats and humans moved their heads along to the beat in a similar rhythm. The level of head bopping from both humans and rats decreased as the music sped up. The study suggests that there is something similar about the way human and rat brains respond to rhythms, but rats do not match their motions to the beat like humans do. Humans can predict the timing of a beat and move predictably to it. 

Aniruddh Patel, a psychologist who studies brain response to music, says humans and parrots respond to beats with big, voluntary movements such as head shaking, dancing or foot tapping. Patel also stresses that this study does not show that rats have the same emotional associations with music as humans do. Yet he believes it could help reveal how humans and some other animals developed a sense of rhythm.
