Ireland，Japan，Chinascientists share the 2015 Nobel Prize for medicine．WilliamCampbell，Satoshi Omuraand Tu Youyou jointly won the prize for their work against diseases，theaward-giving body said on Monday．

Tu Youyou, a scientist at the China Academy of Chinese MedicalSciences, has no postgraduate degree. She has never studied or done researchabroad. She is neither a member of the Chi­nese Academy of Sciences nor theChinese Academy of Engineering. However, the 81-year-old phar­macologist hasbecome the first scientist on the Chinese mainland to win a Lasker Award, themedical prize of the Albert and Mary Lasker Foundation.

The Lasker Awards have existed since 1945. Tu was presented the2011 Lasker Clinical Medical Research Award on September 23. She discovered adrug called artemisinin . The drug is now widely used against malaria .

Tu and her colleagues joined a government project to find a newmalaria drug in the late 1960s during the "cultural revolution"(1966-76).  They made 380 herbal extractsfrom 200 potential recipes. The recipes came from traditional Chinese medicalbooks. The team then tested them on malaria-infected mice.  Finally Tu became interested in an extract ofthe plant qinghao, or sweet wormwood .

According to an ancient Chinese medicine book, qinghao was onceused to treat malaria. However, the extract they made in the lab didn't workwell. Maybe, thought Tu, the effective ingredient in qinghao was destroyed byhigh temperatures. Therefore, Tu tried to make the extract with an ether whichhas a much lower boiling point than water.

In 1971, after more than 190 failures, Tu finally got an extractthat was 100 percent effective against the malaria para­sites .The extract wascalled qinghaosu, later renamed artemisinin.

According to a statement on the Lasker Foundation website,during the past four decades, Tu's drug has saved millions of lives. It isespecially important for children in the poorest and least developed parts ofthe world. However, not many people knew of the scientist until she won theLasker Award this month.

Lasker Awards are known as "America's Nobels" for thereason that in the last two decades, 28 Lasker Prize winners have gone on toreceive the Nobel Prize, and 80 since 1945, according to Xinhua News Agency.

" The discovery of artemisinin is a gift to mankind fromtraditional Chinese medicine," Tu said when she received the a-ward."Continuous exploration and development of traditional medicine will,without doubt, bring more medicines to the world.

    America's businesses are getting older and fatter, while many new businesses are dying in infancy.

    A study last month by the Brookings Institution found that the proportion of older firms has grown steadily over several decades, while the survival rate of new companies has fallen. In addition, young people are starting companies at a sharply lower rate than in the past.

    A new report from the National Association of Manufacturers shows a major cause: The cost of obeying government regulations has risen to more than $2 trillion (12.26 trillion yuan) annually, or 12 percent of the GDP, and this cost falls disproportionately on smaller, newer businesses.

    It's risky, difficult and expensive to start a business, and getting more so. Governments are imposing various new rules on a seemingly daily basis: health insurance, minimum wage increases and, most recently in California, compulsory paid sick days for even hourly employees. These regulations shift huge social welfare costs directly onto often-struggling small businesses, while being proportionally much less costly for larger companies.

    This is partly an unintended issue of resources—established companies can cope with new costs more easily—but it's also deliberate. For instance, big insurance companies got a seat at the table to help write Obamacare, but less politically powerful firms—like medical device manufacturers—got squeezed.

    Mature, successful corporations can employ ex-lawmakers with connections, distribute campaign contributions and even write regulations for themselves. They are also more likely to want to protect steady revenue streams than revolutionize their industry.

    Major companies that have been so ill-managed they would otherwise collapse—airlines, car companies and banks—stagger（蹒跚）on because politicians ride to the rescue with bags of taxpayer money.

    The genius of our unique system of government is the determination to protect and defend the rights of the individual over the rights of the nation. As such, the rise of a well-connected oligarchy（寡头政治）that protects big business at the expense of small business, and the established over the new, is opposite to American ideals.

    Income inequality—which is directly caused by faulty government policy—is being promoted as the reason to impose more of that bad policy. But let's be perfectly clear, we do not have a free market but one where government picks winners and losers through regulations and financial aids.

    Politics is, and always has been, about balancing competing interests seeking to benefit themselves, and that's as it should be, but the force of government should never be used to reduce competition, kill innovation or support and extend artificial monopolies（垄断）by harming the consumer, the taxpayer and the economy. Policy must breed our new and small businesses or see the as-yet undreamed of innovations that could be our bright future die in infancy.

    The famous director of a big and expensive movie planned to film a beautiful sunset over the ocean, so that the audiences could see his hero and heroine in front of it at the end of the film as they said goodbye to each other forever. He sent his camera crew out one evening to film the sunset for him.

    The next morning he said to the men, “Have you provided me with that sunset?”

    “No, sir,” the men answered.

    The director was angry. “Why not?”  he asked.

    “Well, sir,” one of the men answered, “we're on the east coast here, and the sun sets in the west. We can get you a sunrise over the sea, if necessary, but not a sunset.”

    “But I want a sunset!” the director shouted. “Go to the airport, take the next flight to the west coast, and get one.”

    But then a young secretary had an idea. “Why don't you photograph a sunrise,” she suggested, “and then play it backwards? Then it'll look like a sunset.”

    “That's a very good idea!” the director said. Then he turned to the camera crew and said, “Tomorrow morning I want you to get me a beautiful sunrise over the sea.”

    The camera crew went out early the next morning and filmed a bright sunrise over the beach in the middle of a beautiful bay. Then at nine o'clock they took it to the director. “Here it is, sir,” they said, and gave it to him. He was very pleased.

    They all went into the studio. “All right,” the director explained, “now our hero and heroine are going to say goodbye. Run the film backwards so that we can see the ‘sunset' behind them.”

    The “sunset” began, but after a quarter of a minute, the director suddenly put his face in his hands and shouted to the camera crew to stop.

    The birds in the film were flying backwards, and the waves on the sea were going away from the beach.

Sharks have been swimming in the ocean for millions of years. They were on Earth even before dinosaurs! At the top of the world's ocean's food chain, sharks help keep the population of other ocean animals in balance. A large drop in the number of sharks can cause serious problems for all ocean animals. Saving sharks makes sense!

Many people are afraid of sharks. But most sharks are harmless. Only a small percentage of sharks are known to attack humans. It adapt (适应) well to new habitats and eat whatever is available. However, today, sharks are in trouble. Nearly one－third of the 400 shark species are in danger of extinction, largely due to over－fishing. Each year, tens of millions of sharks are caught and killed just for their fins. The fins are used to make shark fin soup.

Humane Society International (HSI) joined with the Jane Goodall Institute's Roots and Shoots program and Beijing Zoo to protect sharks. An exhibit at the zoo, "the Price Behind the Taste—Protect Sharks. Don't Eat Shark Fins", was designed to tell people that shark finning is cruel and unnecessary. It's hoped that the activity will help put an end to the practice.

Shark fin soup is also eaten in the United States. In fact, the numbers of some shark species in US waters have dropped 90 percent in the last 30 years. To slow the fall, laws against the sale of shark fins have been passed in several states, including Hawaii, Oregon, Washington, and California.

Last August, the 900-year-old Wan'an Bridge in Pingnan County, a locality of Ningde City in the coastal Fujian province, was destroyed when it suddenly caught fire.

Wan'an, a national-level protected building, was a wooden arch corridor bridge (木拱廊桥),which for centuries was an ancient architectural calling card for the region. The bridge,98.2 meters long and 4.7 meters wide, was first built in the Song dynasty (960~1279), and was the longest wooden arch corridor bridge left standing in China. Few, however, had imagined that such an ancient bridge would attract public attention in such a way.

Amid the powerful voice of the local population for new wooden arch bridges, the traditional techniques behind the building work have well and truly been revived (唤醒), but the protection of the ancient buildings still has much room for improvement.

Currently, China's approach to the protection of national heritage sites puts protecting and rescuing endangered buildings before all else, but to keep these ancient buildings alive, preventive protection is key.

"Technically, restoring (修复) Wan'an isn't very difficult," said Li, Deputy County Mayor of Pingnan. "Along with the help of the local inheritors of the national intangible cultural heritage, the bridge's restoration looks hopeful. However, the historical value will definitely be affected."

Meanwhile, Zhan, the former Deputy Dean at the Chinese Academy of Cultural Heritage, pointed out the recent destruction of Wan'an Bridge highlights a serious shortage of warning mechanisms and preventative protection measures, which currently are supposed to be the most important part of protection. "Significant improvements have been made in the past few years in protection, but we still have a long way to go on proper planning for protection work. How to protect cultural heritage is a matter that we need to discuss as soon as possible," he added.
