You never played the video dance game? Now such games are used to help lose weight!

    Like many other teenage boys, Jones loves sports. But at 5 feet, 175 pounds, he found his weight in trouble. His doctor wanted him to lose 50 pounds so that he may be a good football game player by the end of the summer.

    Jones chose the popular Dance Revolution video game at home to increase his activity. He had lost about 10 pounds by changing his diet. Now, after two weeks' playing the game, he has lost another 10!

    A health study is being done by an insurance company. The company hopes that the game will lead to better health and lower costs. “Obesity claims last year cost us $ 77 million. We have to cut those costs,” said a member of the insurance group. The company provides a game console (游戏主机), a dance mat and software for the six-month, $ 60,000 study.

    The study is more than a commercial thing of an insurance company. It is widely supported by physical education and health professionals.

    In West Virginia, 43% of the nearly 6,000 children examined for heart disease risk were considered over-weighted; more than 25% were too fat. “We are in a crisis of childhood obesity not only in West Virginia but in America,” said a researcher.

    Researchers are now looking at the potential for improving effects by using the game. A teacher in West Virginia has been using the video games in her classes since last fall. She reported that the game does improve heart health as well as eye-hand coordination (协调能力), and her students take the video game as a great alternative to jumping rope or ball games.

    The US Education Department is putting the game in 20 schools to control childhood obesity. Well, are you going to try such to dance away your extra weight?

    Master painter Zhang Daqian (1899-1983) was well known for having a large number of friends and students. Among them, painter Li Qiujun was special.

    They got to know each other through Li's elder brother, who was one of Zhang's best friends.

    They admired each other's artistic talent and became confidants, which resulted in a romantic relationship.

    In 1948, Zhang produced Spring Clouds Amid Autumn Landscape, a mountain-and-water ink painting featuring gongbi (meticulous brushwork), as a gift for Li's 50th birthday.

    A year later, Zhang permanently departed from the mainland, and traveled and exhibited around the world before settling down in Taipei in 1976.

    After leaving the mainland, he often said that he missed Li, who died in Shanghai in 1973.

    Spring Clouds Amid Autumn Landscape will be auctioned in Hong Kong on Oct 4.

    The painting not only marks a friendship between the two painters, but it deserves special attention because it shows Zhang at the top of his game as he sought to master the mountain-and-water style, according to C.K. Cheung, head of Sotheby's Chinese painting department.

    Sotheby's will auction the work at its major autumn sale, which runs from Oct 1 to 5.

    Cheung says the painting's composition and Zhang's attention to details reflect his incorporation of traditional touches, especially from Song Dynasty (960-1279) paintings, while also developing his own style.

    More than four decades ago British scientist Robert Edwards first witnessed the miracle of human life growing inside a test tube at his Cambridge lab. Since that ground-breaking moment, more than four million babies have been born through IVF and in 2010 his great contribution to science was finally recognized as he was awarded the Nobel Prize for medicine.

    The prize for Dr. Edwards, who was given a Daily Mirror Pride of Britain Award in 2008, includes a £900,000 check. The Nobel Assembly described IVF as a “milestone in modern medicine”.

    With the help of fellow scientist Patrick Steptoe, the Manchester-born physiologist developed IVF — leading to the birth of the world's first test tube baby. Dr. Steptoe died 10 years later but their work has transformed fertility treatment and given hope to millions of couples.

    It was a scientific breakthrough that transformed the lives of millions of couples. They said: “His achievements have made it possible to treat infertility, a disease which makes human unable to have a baby. This condition has been afflicting a large percentage of mankind including more than 10% of all couples worldwide.”

    Louise Brown, the world's first test tube baby, made international headlines when she was born in Oldham, Gtr Manchester, in 1978 to parents Lesley and John who had been fruitlessly trying for a baby since 1969.

    Ivf-in-vitro fertilization is the process whereby egg cells are fertilized outside the body before being implanted in the womb. After a cycle of IVF, the probability of a couple with infertility problems having a baby is one in five—the same as healthy couples who conceive naturally.

    Professor Edwards, who has five daughters and 11 grandchildren, began his research at Cambridge University in 1963, after receiving his PhD in 1955. He once said: “The most important thing in life is having a child. Nothing is more special than a child.” With the help of fellow scientist Patrick Steptoe, Prof. Edwards founded the Bourn Hall clinic in Cambridge shire, which now treats more than 900 women a year. Each year, more than 30,000 women in Britain now undergo IVF and 11,000 babies are born as a result of the treatment.

    But his work attracted widespread criticism from some scientists and the Catholic Church who said it was “unethical and immoral”.

    Martin Johnson, professor of reproductive sciences at the University of Cambridge, said the award was “long overdue”. He said: “We couldn't understand why the Nobel has come so late but he is delighted — this is the cherry on the cake for him.”

    Professor Edwards was too ill to give interviews but a statement released by his family said he was “thrilled and delighted”.

    My arms shook. The bow was almost as tall as I was, and it was equipped with an arrow, ready to be shot. Never had a more ill-suited person handled a weapon. But my editor had sent me on a mission: to find my inner Katniss Ever deen at one of Beijing's indoor archery clubs.

    The brilliant archer Everdeen is the lead character in The Hunger Games movies, the final of which was just released in cinemas. Her arrows can hit almost anything: sword-swinging enemies, fierce animals, even aircraft some-how. Me? I can't throw a paper ball into a trashcan with any precision. And I was warned that archery would require a great deal of upper body strength, though I hadn't seen the inside of a gym in years.

    News outlets like the New York Times and NPR have reported an increase of interest in archery, thanks to movies like The Hunger Games, Brave and The Avengers. Archery clubs have showed up in many major cities. In Jian Club, an archery-themed bar, we paid 120 yuan for an hour's worth of target practice and prepared our bows and arrows.

    We were told to stand sideways, with one shoulder facing the bull's eye. Your weaker arm would hold the bow, while the other would pull the bowstring back until the arrow was right next to your face. Then it was meters away.

    Well, sort of. Instead of sending the arrows whistling through the air, my first few simply dropped onto the ground.

    The failure was a good reminder that archery is a demanding, Olympic-level sport. It worked muscles in my back and arms that I just didn't have yet. An hour came and went, and I found myself leaving with a couple pierced (刺穿的)bull's eyes and sore shoulders. Was I ready to shoot down aircraft with a swift arrow? Not quite. But I was definitely ready for a return trip.

    Try this: For an entire day, forget about the clock. Eat when you're hungry and sleep when you're tired. What do you think will happen?

    You may be surprised to find that your day is much like most other days. You'll probably get hungry when you normally eat and tired when you normally sleep. Even though you don't know what time it is, your body does. These patterns of daily life are called circadian rhythms(生理节奏), and they are more than just habits. Inside our bodies are several clocklike systems that follow a roughly 24-hour cycle. Throughout the day and night, our inner clocks direct changes in temperature, body chemicals, hunger, sleepiness and more.

    Everyone's rhythms are different, which is why you might like to stay up late while your sister always wants to go to bed early. But on the whole, everyone is programmed to feel tired at night and energetic during the day. Learning about our body clocks may help scientists understand why problems arise when we act out of step with our circadian rhythms. For example, traveling across time zones can make people wake up in the middle of the night. Regularly staying up late can make kids do worse in tests.

    "There is a growing sense that when we eat and when we sleep are important parts of how healthy we are," says Steven Shea, director of the Sleep Disorders Program at Brigham and Women's Hospital in Boston.

    One way to learn about how our body clocks tick is to mess them up and see what happens. That's what neurologist(神经病学家)Frank Scheer and his workmates did in a recent study. Staying up night after night, their studies suggest, could make kids extra hungry and more likely to gain weight. And regularly sleeping too little, Scheer says, may be one cause of the recent increase in childhood obesity.

    Depression and suicidal thoughts have doubled in young Americans, according to a new study from the American Psychological Association.

    Likely triggers? Cell phones and social media.

    "More US adolescents and young adults in the late 2010s, vs the mid-2000s, experienced serious psychological distress, major depression and more attempted suicide (自杀)", says lead researcher Jean Twenge, professor of psychology at San Diego State University. "These trends are weak or non-existent among adults 26 years and over, suggesting a generational shift in mood disorders instead of an overall increase across all ages."

    Twenge believes this trend is partially due to the explosion of digital culture over the past decade, which may have twisted modes of social interaction enough to affect mood disorders.

    The study analyzed data from the National Survey on Drug Use and Health, which tracked drug and alcohol use and mental health issues in more than 200,000 youths aged 12 to 17 from 2005 to 2017 and almost 400,000 adults from 2008 to 2017.

    Major depression in the last 12 months increased by 52 percent in kids from 2005 to 2017 and 63 percent in young adults aged 18 to 25 from 2009 to 2017. There was also a 71 percent jump in young adults experiencing serious psychological distress in the previous 30 days from 2008 to 2017.

    So what's so different now? Twenge says research shows young people just aren't getting as much shuteye as they did in previous generations.

    Whereas older Americans might have established more stability in their lives, sleep-disrupting social stressors are likely at their peak for teens and young adults in this digital era, she says. Older adults are also less likely to let devices interfere (干预) with sleep.

    These results suggest a need for more research to understand how digital communication versus face-to-face social interaction influences mood disorders and to develop specialized interventions for younger age groups.

    Her suggestion? Put your phone down at least an hour before bedtime.
