There are countless short videos on YouTube. It's a website for people to post video made by themselves. Many people make a lot of money through doing so. Then, who made the most over the past year?

    YouTube's top-earning celebrity is a 25-year-old video-game-playing young man who shows a strong sense of humor in his videos. He earned $12 million over the past year. Forbes magazine says Sweden's Felix Kjellberg, better known by his handle "PewDiePie", tops its first list of people who have turned short videos into huge piles of cash.

    YouTube stars make money mainly by getting paid to interact with products on their channels and sharing ad revenue(收入) with YouTube. Some also star in movies, write books, go on tour, or sell music. They're a hit with younger audiences and brands trying to reach the next generation of consumers.

    Two acts tied for the second place on Forbes' list, both earning $8.5 million: comedy prankster(搞恶作剧的人) duo Smosh(Ian Hecox and Anthony Padilla) and the Fine Brothers(Benny and Rafi Fine). Dancing violinist Lindsey Stirling ranked fourth with $6 million. Tied for fifth were comedians Rhett and Link(made of Rhett McLaughlin and Charles Lincoln III) and video game commentators(解说员) Olajide Olatunji, known as "KSI," with $4.5 million. Make-up artist Michelle Phan was seventh at $3 million. The No. 8 place was a three-way tie at $2.5 million shared by comedian Lilly Singh, or "Superwoman;" prankster Roman Atwood; and chef Rosanna Pansino.

    Forbes is best known for its list of billionaires and this list marks its first attempt at ranking YouTube stars. It says it measured earnings before management fees and taxes and came up with the figures based on data from online sources such as Nielsen, IMDb and interviews with managers, lawyers, industry insiders and the stars themselves.

    The health of millions could be at risk because supplies of medicinal plants are being used up. These plants are used to make traditional medicine, including drugs to fight cancer. “The loss of medicinal plants is a quiet disaster,” says Sara Oldfield, secretary general of the NGO Botanic Gardens Conservation International.

    Most people worldwide rely on herbal (药草制的) medicines which are got mostly from wild plants. But some 15,000 of the 50,000 medicinal species are under threat of dying out, according to report from the international conservation group Plantlife. Shortages have been reported in China, India, Kenya, Nepal, Tanzania and Uganda.

    Over-harvesting does the most harm, though pollution and competition from invasive species (入侵物种) and habitat destruction all contribute. Businessmen generally harvest medicinal plants, not caring about sustainability (可持续性),” the Plantlife report says, “damage is serious partly because they have no idea about it, but it is mainly because such collection is unorganized”. Medicinal trees at risk include the Himalayan yew (紫衫) and the African cherry, which are used to treat some cancers.

    The solution, says the report's author, Alan Hamilton, is to encourage local people to protect these plants. Ten projects studied by Plantlife in India, Pakistan, China, Nepal, Uganda and Kenya showed this method can succeed. In Uganda, the project has kept a sustainable supply of low-cost cancer treatments, and in China a public-run medicinal plant project has been created for the first time.”

    “Improving health, earning an income and keeping cultural traditions are important in encouraging people to protect medicinal plants,” says Hamilton, “You have to pay attention to what people are interested in.”

Ghillean Prance, the former director of the Royal Botanic Gardens at Kew in London, agrees that medicinal plants are in need of protection. “Not nearly enough is being done,” he told New Scientist. “We are destroying the very plants that are of most use to us.”

    Chinese New Year has been welcomed in Britain with its biggest ever program of events and celebrations.

    From London's Trafalgar Square to major cities across Britain, tens of thousands of British people have joined Chinese communities to celebrate the arrival of the Year of the Rooster.

    In Manchester there was a Dragon Parade, led by a spectacular 54-meter long dragon, ending is Chinatown where there was traditional Chinese entertainment, more than 6,000 lanterns, street food villages and a fireworks show. Celebrations also took place in Liverpool. Birmingham, Lake District, Durham, Edinburgh. Leeds and Newcastle.

    Academic Dr. Wu Kegang said that the Chinese New Year event in Britain “is now bigger than ever and it is growing every year.”

    When Wu arrived in Britain 26 years ago from Guangdong, south China, the first thing he noticed was that Chinese New Year was celebrated mainly in towns and cities with big Chinese communities. “You would go to London Chinatown and join your countrymen to celebrate, or to Chinatowns in places like Liverpool and Manchester for what were events almost exclusively held for Chinese people,” Wu recalled.

    “Now it is so different, and we are seeing local communities all over the country taking part alongside their own Chinese populations,” he said. “It is clear to me that the celebrations will continue to grow in Britain. Chinese New Year has earned its place in the calendar of events in Britain, and is here to stay.”

    Shop with Your Doc is part of a broader and still growing movement in US medicine to shift the focus away from simply treating disease toward caring for the whole person. It is meant to help people make educated, healthy choices one grocery cart at a time. Across the country, hospitals are setting up food banks and medical schools are putting cooking classes on the curriculum. Nonprofits are connecting medical centers with community resources to ensure that low-income Americans have access to fresh fruits and vegetables.

    For centuries, Western medicine's mission was to cure disease. But over the past generation, two generation, two significant trends are of concern to the medical community, says Timothy Harlan, executive director of Goldring Center for Culinary Medicine at Tulane University in New Orleans. Healthcare costs began to soar (激增), and relatively inexpensive, poor-quality food became more common. "There's a very straightforward link between people improving their diets and improving the condition that they have," Dr. Harlan says.

    The connection drove the medical and nonprofit communities to rethink their approach to health. What emerged was the concept of the "social determinants of health"—the notion of taking into account the biological, physical, and socioeconomic circumstances surrounding a patient. A healthy person isn't just someone who is free from disease, the theory goes; he or she also enjoys "a state of complete mental, physical and social well-being."

    The question the medical community now faces is how to get patients—especially low-income families—to recognize these determinants and make it possible for them to eat and live healthier. In Boston, medical experts responded by creating an on-site pantry (食品室) at Boston Medical Center. Since its founding in 2002, the pantry has evolved into a kind of nutrition center where primary care providers at BMC send patients for food. Today the pantry, which gets 95 percent of its stock from the Greater Boston Food bank, hosts free cooking classes and serves about 7,000 people a month. The Greater Boston Food Bank has also launched its own initiatives, striking partnerships with four community health centers across the state to offer free mobile produce markets. The organization also helped develop toolkits (软件包) that map local pantries, markets that accept government food vouchers, and other resources.

    At Tulane in New Orleans, Harlan is leading the development of a curriculum that combines medicine with the art of food preparation. His philosophy: Doctors who know their way around a kitchen are better at helping their patients. And empowering patients to take charge of their own diets is one way to help them deal with the incredible costs of health care, Harlan says. The curriculum has since been adopted at 35 medical schools around the United States. Chipping away at bad habits is a good place to start getting patients to think about the choices they make for themselves and their families, say Dr Maureen Villasenor, the Orange County pediatrician (儿科医生).

    Researchers in Australia, who studied 1,500 people and their lifestyles, have found that having good friends can help you live longer. An American study of 10,000 students, over a period of 35 years, also found that if you make more friends than the average (普通的) person at school, you'll receive a higher salary (工资) in later life. People need good social skills at work to manage people and work in a team successfully. These are the same skills we use to make friends at school.

    On average, teenagers aged between 15 and 17 have 500 “friends” on their favourite social networking site. Adults (成年人) have 130. So if you believe this research, you might live for a long time and be very rich.

    However, according to Professor Robin Dunbar from the University of Oxford, it probably won't make any difference. Dunbar studied the number of messages between users of a popular social networking website, each of whom had between 200 and 2,000 friends. He found that they always communicate with a maximum (最大量) of 150 people.

Among these 150, Dunbar believes that around five people are close friends. You've most likely known them for a long time; they are probably old friends and you share all your good and bad experiences with them. Then there are ten more friends. Although they're close to you, you may not keep in touch with them every week. Next there are 35 people who you might spend time with because of a shared interest. You aren't close. And finally, there's a large group of 100. You see or speak to these people at least once a year, but you don't know them well. Beyond (超过) this number, Dunbar says, it's impossible to make any relationship meaningful.

    If you have a lot of online "friends", try this experiment: First take away anyone you haven't been in touch with for a year. Then remove people you can't remember and, finally, take away friends who you wouldn't mind losing touch with. How many do you have left? How many of these people are actually good friends? According to the research, these are the only people that really matter.

Nowadays, the term "superfood" has become the nutritional buzzword. Simply put, these superfoods are those that provide large amount of nutrients through minimal calories.
