A glass a day keeps obesity at bay．Alcohol has always been thought to cause weight gain because of its high sugar content, but new research suggests a glass a day could form part of a diet．Looking at past studies they found that, while heavy drinkers do put on weight, those who drink in moderation can actually lose weight．
A spokesman for the research team at Navarro University in Spain says, “Light to moderate alcohol intake, especially of wine, may be more likely to protect against, rather than promote, weight gain”．The International Scientific Forum on Alcohol Research reviewed the findings and agreed with most of the conclusions, particularly that current data do not clearly indicate if moderate drinking increases weight．
Boston University’s Dr．Harvey Finkel found that the biologic mechanisms (生物学机制) relating alcohol to changes in body weight are not properly understood．His team pointed out the strong protective effects of moderate drinking on the risk of getting conditions like diabetes(糖尿病)，which relate to increasing obesity．Some studies suggest that even very obese people may be at lower risk of diabetes if they are moderate drinkers．
The group says alcohol provides calories that are quickly absorbed into the body and are not stored in fat, and that this process could explain the differences in its effects from those of other foods．They agree that future research should be directed towards assessing the roles of different types of alcoholic drinks, taking into consideration drinking patterns and including the past tendency of participants to gain weight．
For now there is little evidence that consuming small to moderate amounts of alcohol on a regular basis increases one’s risk of becoming obese．What’s more, a study three years ago suggested that reveratrol, a compound present in grapes and red wine, destroys fat cells．

In my first week as a graduate student at Cambridge University in 1964 I met with a fellow student, two years ahead of me in his studies; he was unsteady on his feet and spoke with great difficulty．This was Stephen Hawking．I learned that he had a bad disease and might not live long enough even to finish his PhD degree．
But, amazingly, he has reached the age of 73．Even mere survival would have been a medical miracle, but of course, he didn’t merely survive．He has become arguably the most famous scientist in the world for his brilliant research, for his bestselling books, and, above all, for his astonishing victory over hardship．
Stephen received his “death sentence” in 1964, when I thought it was hard for him to go on with his study．Stephen went from Albans School to Oxford University．He was said to be a “lazy” undergraduate, but his brilliance earned him a first class degree, an “entry ticket” to a research career in Cambridge and a uniquely inspiring achievement．Within a few years of the burst of his disease he was wheelchair bound, and his speech was so unclear that it could only be understood by those who knew him well．But his scientific career went from strength to strength: he quickly came up with a series of insights into the nature of black holes (then a very new idea) and how the universe began．In 1974 he was elected to the Royal Society at the exceptionally early age of 32．
The great advances in science generally involve discovering a link between phenomena that were previously conceptually unconnected — for instance, Isaac Newton realized that the force making an apple fall to earth was the same as the force that holds the moon and planets in their orbits．Stephen’s revolutionary idea about a link between gravity and quantum(量子) theory has still not been tested．However, it has been hugely influential; indeed, one of the main achievements of string theory(弦理论) has been to confirm and build on his idea．He has undoubtedly done more than anyone else since Einstein to improve our knowledge of gravity and he is one of the top ten living theoretical physicists．

Sina Weibo, one of the country’s most popular micro blogging sites,has launched a paid service．For a 10 yuan ($ l．57) monthly fee, users get a membership on their Sina Weibo accounts．
According to Xu Yuanyuan, a member of the marketing team at Sina, themove is to guarantee a more convenient and safer environment for users．But despite the company’s efforts to increase income, it seems that most of its 300 million users still prefer the free version．
The premium membership (高级会员) plans ,announced by the company on Monday, brought about negative comments from its users ．
“The current service is good enough for me”, said a Beijing based micro blogger．“I don’t really need those value added services and it might be a waste of money．I might consider paying for it if some more features are added．”
Dong Xu, an analyst with consulting firm Analysys International, said that Sina shouldn’t expect a great increase in income brought by the new services．The free services are enough for most users, Dong said．“The company has been making attempts at different profit models since last year．A potential source of income could be gaming．Games and advertisements are so far the two biggest sources of income．” she said．
Other micro blogging service providers have not yet followed suit．Fang Gang, vice president of rival Sohu, said via e mail on Tuesday that Sohu’s micro blogging service will never charge users．“It’s good news for us．Users can come to our website if they have to pay for services (at Sina)．” Fang said．

Every day we are exposed to images, videos, music and news．In this age of visual and aural hyper stimulation, the medium of radio is making a great comeback.
“We’re at the beginning of a golden age of audio,” said US based podcaster Alex Blumberg in an article in The Sydney Morning Herald．In the last month alone, 15 percent of US adults listened to a radio podcast (播客)．These statistics, released by Edison Research, show the successful evolution of traditional radio broadcasts to the present day’s digital podcast format．The term “podcast” was invented in 2004, but the trend only started gaining mainstream popularity in recent years．With the sharp increase in consumer demand for smartphones and tablets, podcast sales have jumped.
The appeal of the podcast partly lies in its multiplatform delivery and on demand capabilities (功能)．You can listen during those extra minutes of the day when you’re walking to the shops, waiting in a queue or riding the subway．Similar to television shows, podcasts are generally free to download and most offer new content every week.
Donna Jackson, 22, Sydney University media graduate, listens to podcasts two or three times a week, via iTurns．“I listen while I’m wandering around the house doing something else．It makes completing a boring task much more enjoyable… And it’s an easy way of keeping in touch with what’s going on in the rest of the world,” she said, “I mainly listen to BBC podcasts, but recently I’ve also been listening to This American Life and Serial．They have a special skill to really draw you in.”
Unlike television and music, the audio format has the potential to create a deep impression on readers．Blumberg says this owes to the podcast’s ability “to create close relationship and emotional connection.” Sydney University undergraduate Hazel Proust, majoring in social work and arts, agrees．“When you’re listening, it feels as if the voice of the podcast’s storyteller is talking directly to you．It’s comforting, ” said Proust.
It seems the age old tradition of verbal storytelling is very much alive and well.

The Tokyo Metro and Toei Lines	Features: The Tokyo Metro and Toei lines that compose Tokyo’s massive(庞大的)subway system carry almost 8 million people each day, making it the busiest system in the world. The system is famous for its oshiya— literally, “pusher”— who pushes passengers into crowded subway cars so the doors can close. And you think your commute (上下班路程) is hell.
The Moscow Metro	Features: The Moscow Metro has some of the most beautiful stations in the world. The best of them were built during the Stalinist era and feature chandeliers(枝形吊灯), marble moldings and elaborate murals(精美的壁画). With more than 7 million riders a day, keeping all that marble clean has got to be a burden.
The Hong Kong MTR	Features: The Hong Kong MTR has the distinction of being one of the few subway systems in the world that actually turns a profit(利润). It’s privately owned and uses real estate development along its tracks to increase income and ridership. It also introduced “Octopus cards” that allow people to not only pay their fares electronically, but buy stuff at convenience stores, supermarkets, restaurants and even parking meters. It’s estimated that 95 % of all adults in Hong Kong own an Octopus card.
Shanghai Metro	Features: Shanghai is the third city in China to build a metro system, and it has become the country’s largest in the 12 years since it opened．Shanghai Metro has 142 miles of track and plans to add another 180 miles within five years. By that .point, it would be three times larger than Chicago “L”. The system carries about 2.18 million people a day.
The London Metro	Features: Londoners call their subway the Underground, even though 55 percent of it lies above ground. No matter when you’ve got the oldest mass-transit system in the world, you can call it anything you like．Trains started in1863 and they’ve been running ever since. Some 3 million people ride each day, every one of them remembering to “Mind the gap”.
