Darek Fidyka, a 38-year-old Bulgarian, had been paralyzed (瘫痪的) from the chest down for four years after a knife attack. Scientists from Britain and Poland took cells from his nose, transplanted (移植) them into his back and re-grew his spinal cord (脊髓). Now he can walk and even drive a car. The doctors were delighted but said it was the first step in a long journey.

    The breakthrough came after 40 years of research by Professor Geoff Raisman, who found that cells had the possibility to repair damage to nasal (鼻腔的) nerves, the only part of the nervous system that constantly re-grows. “The idea was to take something from an area where the nervous system can repair itself and put it into an area that doesn't repair itself,” Professor Raisman said.

    Polish doctors injected (注射) the nasal cells into Mr Fidyka's spinal cord above the injury and used some nerves from his ankle to form a bridge across the damaged tissue. The nasal cells appear to have caused the spinal nerves to repair themselves.

    Professor Raisman achieved this with rats in the late 1990's, but this is his greatest success. “I think the moment of discovery for me was Christmas in 1997 when I first saw a rat, which couldn't control its hand, put its hand out to me. That was an exciting moment, because I realized then that my belief that the nervous system could be repaired was true.”

    Doctors chose the easiest case for their first attempt—it might not work for others. But there is a real sense of hope that an idea once thought impossible has been realized.

    David Nicholls, who helped provide money for the breakthrough, said information about the breakthrough would be made available to researchers across the globe.

    “What you've got to understand is that for three million paralyzed people in the world today, the world looks a totally brighter place than it did yesterday,” he said.

    How do you get a good night's sleep?

    You may put your pillow (枕头) at the proper height, drink a glass of hot milk or maybe listen to some light music before bedtime. {#blank#}1{#/blank#}When World Sleeping Day falls on March 21, it will be a good time to explore a long-ignored fact that may make you feel tired after you wake up. Scientists have discovered that the position of your spine (脊椎) is very important when you sleep.

    {#blank#}2{#/blank#}Let's have a look at the advantages and disadvantages of each position.

On your back

    Sleeping on your back is the ideal (理想的) position to be in. First of all, your spine is in the best position.{#blank#}3{#/blank#}The downside is the greater likelihood of snoring (打鼾) and sleep apnea (窒息).

Lying on belly

    {#blank#}4{#/blank#}Dr Vaclav Vojta, a US child development specialist, said this is bad for your back because it takes away the natural curve (曲线) of your lumbar (腰部的) spine. But he also noted that this helps to prevent some snoring and sleep apnea.

On your side

    Sleeping on our sides happened naturally while we were in the womb (子宫).{#blank#}5{#/blank#}Plus, sleeping on your side (the left side in particular) has been reported to reduce troublesome digestive problems like heartburn. The downside is the “dead arm” and finger numbness (麻木) from this position.

A. Lying face down with your legs straight and your arms right by your sides is a bad idea.

B. Sleeping on your side can be a quick fix for snoring and can help to improve breathing.

C. Do you and your friends ever talk about your sleeping position with each other?

D. And a new study suggests that the sleeping position has something to do with it.

E. Of the three sleeping positions, which one do you usually go for?

F. You are also less likely to have digestive (消化的) problems.

G. But one thing you may tend to ignore is sleeping positions.

    No matter where you travel in Asia, you'll find yourself faced with a new culture. You can start your Asian exploration (探索) by visiting some of these attractive cities first.

    Beijing, China

    Beijing is the second largest city in China and serves as the capital. The city is so old, in fact, that almost every building has some sort of cultural or historic features — no matter how small. Getting around the city you'll find yourself faced with amazing temples (寺庙), the largest palaces in the world, and many works of art that leave you breathless.

    Siem Reap, Cambodia(柬埔寨)

    Siem Reap is the capital city of Siem Reap Province in northwestern Cambodia. Siem Reap has a lot of French and Chinese­style architecture. In the city, there are traditional dance performances, silk farms, fishing villages and a bird sanctuary (保护区) near the Tonle Sap Lake. Siem Reap today, being a popular tourist attraction, has a large number of hotels and restaurants.

    Kathmandu, Nepal(尼泊尔)

    Situated in the heart of the Himalayans, Kathmandu, the largest city and capital of Nepal, is considered to be one of the most outstanding cities in the world today. The shopping districts are world famous and the hotels in Kathmandu are among the most comfortable in the world.

    Kyoto, Japan

    The city of Kyoto served as the capital of Japan from 794 to 1868. No longer the capital, it is known for being the seventh largest city in Japan. Kyoto was destroyed throughout history by fires and war. But now the city is home to more than 1.4 million people, and it presents a modern face to the rest of the world.

    Every city throughout Asia has a story of its own. It's up to you to explore them all and find out exactly what each one has to offer. Enjoy!

    People who often eat nuts appear to live longer, according to the latest study of its kind. The findings, published in the New England Journal of Medicine, suggested the greatest benefit was in those eating them on their daily diet.

    Eating nuts was linked to a healthier lifestyle including being less likely to smoke or be overweight and more likely to exercise. The British Heart Foundation said more research was needed to prove the link, “While this is an interesting link, we need further research to make sure if it's the nuts that protect heart health, or other sides of people's lifestyle .”

    The study followed nearly 120,000 people for 30 years. The more regularly people ate nuts, the less likely they were to die during the study. People eating nuts once a week were 11% less likely to have died during the study than those who never ate nuts. Lead researcher Dr. Charles Fuchs, from the Dana-Farber Cancer Institute and Brigham and Women's Hospital, said, “The most obvious benefit was a decrease of 29%in deaths from heart disease, but we also saw a significant reduction-11%- in the danger of dying from cancer.”

    They suggest nuts are lowering cholesterol(胆固醇). and insulin resistance(胰岛素抗性). Nuts contain unsaturated fat(不饱和脂肪), protein(蛋白质) and several kinds of vitamins and minerals and they can take the place of snacks like chocolate bars, cakes and biscuits.

    Victoria Taylor, senior expert at the British Heart Foundation, said, “This study shows close connection between regularly eating a small handful of nuts and a lower risk of death from heart disease.” Choosing plain, unsalted foods rather than sweet, salted, or chocolate-covered will keep your salt and sugar intake down.

    Have you ever heard a rumor spread around by students at your school? Rumors, like fake news, can often misinform individuals and lead them to believe false information.

    In an attempt to settle this problem, the country of Singapore has passed a bill that bans companies and individuals from publishing false information online.

    This law, known as The Protection From Online Falsehoods and Manipulation Bill, has caused a public outcry (强烈的抗议), as the government has been given the power to remove content that it considers inaccurate or against the public's interest.

    Since Singapore's citizens are part of different racial and religious groups, the government fears that rumors or fake news can increase tensions within an already small country.

    With the new law coming into effect, Singapore's government now has the authority to monitor news sites, social media platforms, and other databases of information to determine whether the content is falsified. The government can order for the removal of fake news, and publishers of this information can receive prison time and fines up to one million Singapore dollars!

    Critics fear that the bill threatens their freedom of speech and freedom of expression. Since national issues and world news are generally discussed on online platforms, many are concerned that this new bill will prevent individuals from talking freely and having healthy conversations.

    Several companies, including Google, Facebook, and Twitter, have offices situated in Singapore, meaning that the new law will affect their company operations. Social media companies in Singapore could face a decline in activity, as users may fear posting their opinions and being punished by the government.

    Others are concerned that the law does not clearly state what a "false statement" is. Such an ambiguity might allow the government to misuse their power, even though the intention is to curtail the mow of false information and rumors throughout Singapore.

    This law does give rise to several concerns related to freedom and privacy and it will be interesting to see what Singapore's government will do to deal with this problem.

    Doing business nowadays without a cellphone? Living a very private life? I can't imagine it anymore.

    Journalist Chris Stokel-Walker explained it very well: For the average working person, there's no greater feeling than powering down your computer and kissing goodbye to your work emails for the day. If we're lucky enough to disconnect from the job on evenings and weekends, we're overjoyed to leave work emails and the stress that comes with it in the office.

    But experts say we're increasingly failing to do so, instead bringing the burden home with us and dealing with emails during our free time. Unsurprisingly, this routine has some serious consequences.

    Working abnormal or long hours has long been linked with depression(抑郁症), anxiety and even heart disease. In addition, the importance of weekend recovery has also been linked with weekly job performance and personal initiative(主动性). And further research showed psychological detachment(脱离) during off-work time reduced emotional exhaustion caused by high job demands and helped people stay engaged.

    So, if we know all this, it begs the question: Why are we still letting work bother our precious weekend? According to Cary Cooper, professor of Organizational School, the recent trend even spills into the way we access our work communications and projects.

    Today, says Cooper, work emails are just a tap of a smartphone away. "You don't carry your laptop around when you're out to dinner, but you do carry your mobile phone," he says. "The smartphone does not make up for what is lost." So delete your work email account from your inbox(收件箱), and leave the worries until Monday.
