A German fisherman named Konrad Fischer found the brown bottle near Kiel, Germany. He said he nearly threw the bottle back into the water after pulling it out of a fishing net. Then he noticed something inside.

    The bottle in good condition contained a Danish postcard with two German stamps, dated May 17, 1913. Although dampness had made most of the writing illegible（字迹模糊的）, the readable part of the message asked whoever found it to return it to an address in Berlin. It even contained two stamps to pay for postage.

    From the address, researchers found that the postcard was written by a man named Richard Platz, who was 20 years old when he wrote the message. While he was hiking on the Baltic coast with a nature appreciation group. he threw the bottle into the sea. Then the researchers began a search for any living relatives of his. Sure enough, they were able to find his 62-year-old granddaughter, Angela Erdmann, who still lives in Berlin.

  “It was almost unbelievable,”Erdmann said upon being presented with her grandfather's bottle and message.“That was a pretty moving moment. Tears rolled down my face."

    Erdmann never knew her grandfather，who died in 1946，but says that the discovery of the bottle has made her want to learn more about him.

    The bottle remained on display at the International Maritime Museum in Hamburg until May 1st. After that, the researchers examined the postcard and tried to figure out the meaning of the rest of the message.

    Previously, the oldest message found in a bottle spent nearly 98 years at sea and was discovered in April 2012, according to Guinness World Records.

    Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.

    Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses（球场） in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.

    There are many environment-friendly sports. Power walking is one of them that you could take up today. You don't need any special equipment except a good pair of shoes; and you don't have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.

    Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be "green gyms". They are better replacements（代替物）for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it's free.

When someone is happy, can you smell it?

    You can usually tell when someone is happy based on seeing them smile, hearing them laugh or perhaps from receiving a big hug. But can you also smell their happiness? Surprising new research suggests that happiness does indeed have a scent, and that the experience of happiness can be transmitted through smell, reports Phys.org.

    For the study, 12 young men were shown videos meant to bring about a variety of emotions while researchers gathered sweat samples from them. All of the men were healthy and none of them were drug users or smokers, and all were asked to abstain from drinking or eating smelly foods during the study period. 

    Those sweat samples were then given to 36 equally healthy young women to smell, while researchers monitored their reactions. Only women were selected to smell the samples, apparently because previous research has shown that women have a better sense of smell than men and are also more sensitive to emotional signaling—though it's unclear why only men were chosen to produce the scents.

    Researchers found that the behavior of the women after smelling the scents—particularly their facial expressions—indicated a relationship between the emotional states of the men who produced the sweat and the women who sniffed them. 

    “Human sweat produced when a person is happy brings about a state similar to happiness in somebody who breathes this smell,” said study co-author Gun Semin, a professor at Koc University in Turkey.

    This is a fascinating finding because it not only means that happiness does have a scent, but that the scent is capable of transmitting the emotion to others. The study also found that other emotions, such as fear, seem to carry a scent too. This ensures previous research suggesting that some negative emotions have a smell, but it is the first time this has proved to be true of positive feelings.

    Researchers have yet to isolate(分离) exactly what the chemical compound for the happiness smell is, but you might imagine what the potential applications for such a finding could be. Happiness perfumes, for instance, could be invented. Scent therapies（香味疗法）could also be developed to help people through depression or anxiety.

    Perhaps the most surprising result of the study, however, is our broadened understanding of how emotions get communicated, and also how our own emotions are potentially managed through our social context and the emotional states of those around us. 

    If you're dreaming of visiting one of those picture-perfect European towns filled with old-world attractiveness and scenic beauty, here is a look at the most beautiful small towns in Europe.

    Manarola

    Manarola, Italy, is filled with rainbow-colored homes along the Mediterranean(地中海) coast. This attractive fishing town is famous for its unbelievable wine, and the paintings. There are no cars here, no traffic lights, or traffic noise. You can drive to Manarola, but you'll have to park just outside the town and then take a shuttle bus or walk in on foot.

    Garmisch-Partenkirchen

    Garmisch-Partenkirchen, Germany, is a fascinating(迷人的) mountain town. Once two separate(分开的) towns, one Roman and the other Teutonic, the 1936 Winter Olympics forced them to become one, though the two sides still have different characters(特点). The town dates back to 15 AD, filled with narrow, cobblestoned streets lined with historic three or four-story buildings painted with religious scenes(宗教场景).

    Marsaxlokk

    The energetic trading port of Marsaxlokk, Malta, was built in 900 BC. Today, this pictures-like town is the main supplier(供应地) of fish to the island nation that sits in the Mediterranean Sea. It has no modern buildings to ruin its attractiveness. With such quiet surroundings, including the traditional luzzu's (fishing boats), it's a particularly charming(迷人的) place to visit.

    Portmagee, Ireland

    In a country filled with beautiful towns, Portmagee, is a standout, sitting on the southwest coast of Ireland. This postcard-perfect seaside fishing town has a row of brightly colored buildings along with a rich and colorful history. At The Bridge Bar, you'll find live music many nights of the week along with nice food and a fine glass of beer.

    Studying abroad will shape you in various ways. You will learn things you never would have if you had stayed home. When you are young and unattached, you should travel. Besides, you just might save a large sum of money. College is expensive in the United States. It's cheap or free in other countries even for foreigners, so why not get out of here and come back smarter?

    More and more American students are currently studying at German colleges. That number has increased 20% over the last three years. Living costs are about $7,000 a year, which is even lower than in other European countries. Germany encourages international students. They create a multicultural landscape that benefits German students as well. According to a new report, Germany is home to six of the world's 100 best universities. These schools offer around 900 degrees completely in English and many German students speak the language.

    You could be part of Finland's excellent education system. The Finns charge no tuition and offer a number of courses purely in English. They would be happy for you to add flavor to their school scene. Cost of living there is high. Be prepared for frosty winters that far north, but you will get that sweet midnight sun in the summer.

    Many other European nations offer cheap or free college for foreign students, but if South America is more your thing, try Brazil. Most of the education will take place in Portuguese, so if that is in your plan you can study near beautiful beaches and jungles. The University of Sao Paulo and the State University of Campinas are both highly ranked internationally. Your money will go a long way there, too.

    Many of the lessons you will learn will be outside the classroom. Living on the economy in a foreign country will keep you on your toes. You will learn new customs, how to bargain, stay safe, budget and become more flexible with people. There is no better way to learn a language than by immersing yourself in it. At first, it will be the toughest thing you have ever done. Eventually, it will become second nature.
