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.

    Whether in the home or the workplace, social robots are going to become a lot more common in the next few years. Social robots are about to bring technology to the everyday world in a more humanized way, said Cynthia Breazeal, chief scientist at the robot company Jibo.

    While household robots today do the normal housework, social robots will be much more like companions than mere tools. For example, these robots will be able to distinguish when someone is happy or sad. This allows them to respond more appropriately to the user.

    The Jibo robot, arranged to ship later this year, is designed to be a personalized assistant. You can talk to the robot, ask it questions, and make requests for it to perform different tasks. The robot doesn't just deliver general answers to questions; it responds based on what it learns about each individual in the household. It can do things such as reminding an elderly family member to take medicine or taking family photos.

    Social robots are not just finding their way into the home. They have potential applications in everything from education to health care and are already finding their way into some of these spaces.

Fellow Robots is one company bringing social robots to the market. The company's “Oshbot” robot is built to assist customers in a store, which can help the customers find items and help guide them to the product's location in the store. It can also speak different languages and make recommendations for different items based on what the customer is shopping for.

    The more interaction the robot has with humans, the more it learns. But Oshbot, like other social robots, is not intended to replace workers, but to work alongside other employees.“We have technologies to train social robots to do things not for us, but with us,” said Breazeal.

    Living and dealing with kids can be a tough job these days, but living and dealing with parents can be even tougher.

    If I have learned anything in my 16 years, it is that communication is very important, both when you disagree and when you get along. With any relationship, you need to let other person know how you are feeling. If you are not able to communicate, you drift apart. When you are mad at your parents, or anyone else, not talking to them doesn't solve anything.

    Communication begins with the concerns of another. It means that you can't just come home from school, go up to your room and ignore everyone. Even if you just say “Hi”, and see how their day was for five minutes, it is better than nothing.

    If you looked up the word “communication” in a dictionary, it would say “the exchange of ideas, the conveyance （表达）of information, correspondence （通信）, means of communication: a letter or a message”. To maintain (保持) a good relationship, you must keep communication strong. Let people know how you feel, even if it's just by writing a note.

    When dealing with parents, you always have to make them feel good about how they are doing as a parent. If you are trying to make them see something as you see it, tell them that you'll listen to what they have to say, but ask them politely to listen to you. Yelling or walking away only makes the situation worse.

    This is an example: one night, Sophie went to a street party with her friends. She knew she had to be home by midnight after the fireworks, but she didn't feel she could just ask to go home. That would be rude. After all, they had been nice enough to take her along with them. Needless to say, she was late getting home. Her parents were mad at first, not when Sophie explained why she was late, they weren't as mad and let the incident go. Communication is the key factor here. If Sophie's parents had not been willing to listen, Sophie would have been in a lot of trouble.

    Communication isn't a one-way deal: it goes both ways. Just remember: if you get into a situation like Sophie's, telling the other person how you feel-listening is the key factor to communication.

    Babies' main food is rice cereal. But it is often poisoned. Studies have found that many brands contain measurable amounts of inorganic arsenic(无机砷),the most poisonous kind. It's not just nice: an August 2018 study tested 50 foods made for babies, including organic and nonorganic brands such as Gerber, Earths Best, and other popular labels, and found evidence of at least one dangerous heavy metal in every product. Fifteen of the 50 contained enough contaminants(污染物)to pose potential health risks to a child eating one serving or less a day.

    Heavy metals can damage cognitive(认知的)development in children, who are especially at risk because of their smaller size. Inorganic arsenic in drinking water has been found to lower the IQ scores of children by five to six ills. And as heavy metals accumulate in the body over time, they can raise the risk of cancer, diabetes and other physical conditions. Of course, finding you're your favorite brand is contaminated is not a reason to panic. Low levels of exposure for short periods are unlikely to cause serious effects, but parents should focus on reducing the overall levels of these poisonous substances in their children's total diet to limit harm.

    Heavy metals occur naturally on Earth and are present in soil and water. But pesticides(杀虫剂), mining and pollution increase their concentrations, and farming and food manufacturing processes can contribute even more.

    Food makers are clearly of keeping baby food poison-free: roughly a third of the tested products did not contain worrisome metal levels. Some companies are already trying to look into the sources of contamination in their products and try to reduce them. More companies should follow. But the best chance of real change will come with laws. Currently there are no U. S rules on acceptable levels of heavy metals in baby foods.

    The government and the food industry should unite to deal with the serious threat to our children.

    Twenty-five years ago, most young Britons wanted a career in law, to be a doctor, or, if they were creative enough, to take up singing. But today, things stand differently.

    According to a survey by Tesco Mobile, a UK company, the "dream job" of young people aged between 16 and 25 in the UK is a video blogger, or "vlogger". The survey, carried out among 1,002 people, found that as much as 40 percent of them put vlogger as their number one choice on a list of ideal careers.

    This change is undoubtedly as a result of the Internet and social media. They have made it so much easier to reach audience of the world, without having to enter a career in show business in the traditional way.

    In the past, the biggest stars were trained by the Hollywood studios; now, anyone with a computer camera can become a star. Vloggers are the big stars of today because they are normal people interacting with their fans about everyday life."

    However, what people see is only the bright side of being a vlogger and they fail to notice the fact that only those who are successful earn fame and fortune. For every success there are hundreds of others who never get off the starting line. There are the dreams that come true and the dreams that remain dreams forever.

    Although being vloggers is popular, some young people choose to follow careers that don't necessarily earn them fame, but allow them to make good use of the Internet to share their hobbies. Young Israeli David Leshaw, for example, runs a business called the Finishers Club. It's an online platform for runners to keep a record of their races. His job allows him to express his enthusiasm, and is always a learning experience. And that's enough for him.

    Some of the world's most famous musicians recently gathered in Paris and New Orleans to celebrate the first annual International Jazz Day. UNESCO(United Nations Educational, Scientific and Cultural Organization) recently set April 30 as a day to raise awareness of jazz music, its significance, and its potential as a unifying(联合) voice across cultures.

    Despite the celebrations, though, in the U. S. the jazz audience continues to shrink and grow older, and the music has failed to connect with younger generations.

    It's Jason Moran's job to help change that. As the Kennedy Center's artistic adviser for jazz, Moran hopes to widen the audience for jazz, make the music more accessible, and preserve its history and culture.

    "Jazz seems like it's not really a part of the American appetite, "Moran tells National Public Radio's reporter Neal Conan. "What I'm hoping to accomplish is that my generation and younger start to reconsider and understand that jazz is not black and white anymore. It's actually color, and it's actually digital. "

    Moran says one of the problems with jazz today is that the entertainment aspect of the music has been lost. "The music can't be presented today the way it was in 1908 or 1958. It has to continue to move, because the way the world works is not the same, "says Moran.

    Last year, Moran worked on a project that arranged Fats Waller's music for a dance party, "just to kind of put it back in the mind that Waller is dance music as much as it is concert music," says Moran. "For me, it's the recontextualization. In music, where does the emotion(情感) lie? Are we, as humans, gaining any insight(感悟) on how to talk about ourselves and how something as abstract as a Charlie Parker record gets us into a dialogue about our emotions and our thoughts? Sometimes we lose sight that the music has a wider context," says Moran, "so I want to continue those dialogues. Those are the things I want to foster. "
