Tu Youyou, 84, honored with the Nobel Prize in Physiology or Medicine on Oct 5, 2015. She was the first Chinese citizen to win a Nobel Prize in science for her work in helping to create an anti-malaria(疟疾) medicine. In 1967, Communist leader Mao Zedong decided there was an urgent national need to find a cure for malaria. At the time, malaria spread by mosquitoes was killing Chinese soldiers fighting Americans in the jungles of northern Vietnam. A secret research unit was formed to find a cure f or the illness. Tw o years later, Tu Youyou was instructed to become the new head of Mission 523. Researchers in Mission523 pored over ancient books to find historical methods of fighting malaria. When she started her search for an anti-malarial drug, over 240,000 compounds(化合物) around the world had already been tested, without any success.Finally, the team found a brief reference to one substance, sweet wormwood（青蒿）, which had been used to treat malaria in China around 400 AD. The team isolated one active compound in wormwood, artemisinin（青蒿素）, which appeared to battle malaria-friendly parasites（寄生虫）. The team then tested extracts（提取物） of the compound but nothing was effective until Tu Youyou returned to the original ancient text. After another careful reading, she improved the drug recipe one final time, heating the extract without allowing it to reach boiling point.

After the drug showed promising results in mice and monkeys, Tu volunteered to be the first human recipient of the new drug. “As the head of the research group, I had the responsibility.” she explained.

Worlds of Fun

    Location: Worlds of Fun is located off Highway 435 in Kansas City, Missouri.

    History: Worlds of Fun was opened on May 26, 1973, at a cost of 25 million dollars. Loosely themed around the Jules Verne book, Around the World in Eighty Days, the park was founded by Hunt Midwest Company. In 1982, Hunt Midwest bought a nearby waterpark, Oceans of Fun. In 2013, Worlds of Fun and Oceans of Fun were combined to a one ticket admission, providing all guests with access to 235 acres of amusement and water rides.

    Hours: Worlds of Fun is open from April through Halloween.

    Tickets: Buy and print online. Always try to buy your tickets in advance, to save time when you get to the park.

    Reservations: Worlds of Fun sells “Fast Lane” cards that save riders' time by allowing them to bypass the majority of wait for most of rides and attractions including Mamba, Prowler, and Patriot. Ride as many times as you want all day long.

    Strategy: Most visitors tend to begin the day with Prowler, the hottest attraction in the park. Use that tendency to your advantage and head to the Patriot first. After that, try the Dragons. Then work your way back to the Prowler. After riding the Prowler, there is only one coaster left, Mamba. Hit it next. If the park is not very crowded, you can ride Boomerang on the way to Mamba. After riding Mamba, head back for a ride on the Wolf. By then you will have tried most of the popular rides and attractions in the shortest possible time.

    News: In 2017, Worlds of Fun is adding Steel Hawk, a ride that will take guests up 301 feet in the air and spin them at a 45-degree angle for a 60-second flight. Wait to have a try!

    If you think you have two left feet but would love to be a good dancer then why not try your hand at dancing?

    That's exactly what I did five years ago and I immediately fell in love with dancing. To me, dancing is a magical experience: I've become fitter, look younger and feel more confident. I enjoy it so much that I will never give up this healthy pastime.

    It's very sociable as well. You meet people and make new friends while dancing the night away. Haven't you heard stories about how dancing inspired new romances or rekindled (重燃) old ones? My friends Joe and Rena just had their big day a few weeks ago after they met each other at a Ceroc workshop some three years before.

    The word “Ceroc” comes from the French language. Without the complicated footwork, it is easier to pick up by beginners. Another good thing about Ceroc is that while it is a partner dance, you don't have to bring a dancing partner.

    Other popular styles of dancing in the UK include ballroom, belly dancing, lindy hop, salsa, tango and tap dancing, just to name a few.

    No matter what types of dancing you do, one thing is for sure: you will become fitter. For office workers like me, dancing is good cardio exercise after a long day sitting in front of the computer screen. It also strengthens your muscles, improves your coordination(协调) and increases your physical confidence.

    Few people will end up being queens of the dance floor. The aim is not to win a competition but to enjoy the interaction(交流). As long as you do the right moves, keep the rhythm and most importantly keep an encouraging smile to your dancing partners, you will always be a winner!

    My husband David was waiting at the door when our daughter Laura and I came back. It wasn't like him to be home so early. The disbelief on his face told me that something was up.

    "Do you still have a job?"

    "No. Redundant," he answered, looking away from me.

    "OK. We'll figure it out," I replied calmly. I actually had no idea how we were going to figure it out. I immediately started to think of how we'd cut costs and who we should start to get in touch with. That night, after David had fallen asleep, I cried myself to sleep, and frequently sobbed（抽泣） in the shower in the days that followed.

    I knew the loss of David's income would have great effect on us. He had worked for the same company for twenty﹣one years and was our main income. I work at home caring for Laura, and my income is uncertain. We have debts, and job hunting takes time.

    Still, I was more concerned about my husband's emotional state than our financial situation. David's sense of identity was tied to his job. He called his parents to tell them about losing his job, but didn't say a word to anyone else for weeks. He told me that he felt like "a failure".

    It was tough for me to watch David struggle with unemployment. One night several weeks after he lost his job, David woke me just before midnight, sweating, pacing the bedroom floor and saying he didn't feel well. We spent the night in the emergency room waiting to see if he had a heart attack. Thankfully, it was just a serious anxiety attack. It was then that I knew I needed to do more to understand what my husband was going through. Here is what I learned from my own experience﹣and from talking to experts﹣on how to support your loved ones through a job loss.

    Whenever we're introduced to strangers, we make snap decisions about them according to our first impressions. Are they attractive or how much do they earn?

    For most Brits, simply asking someone how much they're worth' financially is considered very impolite. Thankfully, most people are kind enough to drop several hints (暗示)about their relative wealth or successful careers They always post on social media about flying to a meeting for work. They're always wearing clothes with labels big enough to silently scream about how rich they are and how well they're doing.

    It's a worrying trend, and I'm not immune to it. I've felt the warm happiness of knowing I earned more than somebody, and the baseless grey irritation of knowing that I earn less than another. I've checked into places while I know full well that anybody reading it will get jealous.

    It seems as though self-worth is increasingly being tied to the careers we choose and the money we earn. A study in 2013, for example found that nearly 17% of unemployed Americans were depressed compared to almost 6% of those who had a permanent job.

    We need to stop placing so much value on what a person earns. Don't get me wrong-being ambitious is not a fault, and achievements should always be celebrated. But when a person uses their success to judge you negatively it becomes a problem.

    If you want to know what you're really worth, here's a tip: It doesn't have anything to do with your bank account. It's about how many times you've been there for your friends. It's how many times you've been kind to a stranger It's every time you did something unselfish, or told your partner you loved him/her, or treated someone with respect no matter where they were in their own life.

Of the tens of thousands of ships on the ocean bottom, only a handful, less than I percent, contain negotiable treasure, such as gold and jewels. Most give us a different priceless treasure — history. A sunken ship lies in trust, preserved in the airless environment of the sea and those in deep water are especially well protected. A sunken ship, therefore, can be a rare window through which a moment in time is glimpsed.

The wreck of HMS Endurance, which has finally been located deep beneath the icy seas of Antarctica after being lost 110 years ago, was arguably the most valuable shipwreck ever sought. That's because its discovery adds another thrilling new chapter to an already fascinating tale of perseverance and survival that has echoed down the decades and still inspires today.

Incredibly well preserved at a depth of almost two miles, the ship is little changed from the day in November 1914 when it finally sank beneath the ice. Endurance became embedded in ice while crossing Antarctica's Weddell Sea. The video shot by underwater search vehicles shows painted timbers, an undamaged guardrail (护栏), with the name "Endurance" written above the five-pointed symbol of a polar star.

"I tell you, you would have to be made of stone not to feel a bit soft at the sight of that star and the name above," Mensun Bound, the mission's marine archaeologist, told the: BBC. "You can see a porthole (舷窗) that is in Shackleton's cabin. At that moment, you really do feel the breath of the great man upon the back of your neck." Shackleton's leadership was crucial to getting his men out alive. The reason why Shackleton is still applauded as a great man becomes obvious when you consider what he achieved in the face of disasters and hardships during his 1914-16 expedition. The practicality and humanity he showed in the face of severe situations was arguably praised.
