Most people agree that eating healthy food is important. But sometimes making good food choices can be difficult. Now, there are apps that can help people learn about the food they eat to improve their health and their dining out experience.

    Open Table app

    Open Table app helps people choose restaurants when they want to go out to eat. It is a free service that shows users restaurant available based on where and when they want to dine. It gives users points when they make reservations(预定), which can add up to discounts on restaurant visits.

    Max McCalman's Cheese & Wine Pairing app

    Wine and cheese can be a great combination. But which wines go best with which cheeses? Max McCalman's Cheese & Wine Pairing app can help. It provides information about hundreds of different cheeses and suggests wines to pair with each. Max McCalman's Cheese & Wine Pairing app is free.

    HappyCow app

    Vegetarians do not eat animal meat. Vegans do not eat any animal products. The HappyCow app is made for both groups. Users can search for vegetarian-vegan restaurants and stores around the world.

    LocalEats app

    Restaurant chains, like McDonalds, can be found almost anywhere a person might travel. But sometimes travelers want to eat like locals. The LocalEats app is designed for that. It can help you find local restaurants in major cities in the US and in other countries. It costs about a dollar.

    Where Chefs Eat app

     “Where Chefs Eat” is a 975-page book. Most people would not want to carry that around. But there is a much lighter app version of the same name for just $15. Six hundred chefs provide information on 3,000 restaurants around the world on the Where Chefs Eat app.

    Very few people enjoy going to the dentist, especially for a filling. Often fillings need to be replaced during the patients' lifetime. But is filling the cavity (蛀洞)with a foreign material really the best treatment? What if the tooth could repair itself with its own material–dentine(齿质)? Researchers at King's College London have found a process that may replace the traditional method.

    Paul Sharpe of King's College says a new treatment for cavities is simpler. It uses a drug that causes the tooth to fill in the hole naturally with dentine. "It involves putting a drug in the hole. It excites a natural process, which starts to occur anyway following the damage, so you can actually get the big hole repaired and the repair is a production of the natural material, the dentine."

    Usually a new drug requires repeated testing before it is approved for treatment. However, this drug that produces the re-growth in teeth has already been approved. It is a drug used to treat Alzheimer's disease and other disorders of the nervous system. Researchers explain that they use only a small amount and they use it locally. Usually that means the medicine is put directly on the affected area. It does not travel through the patient's blood.

    Nigel Carter heads Britain's Oral Health Foundation. He describes the new treatment as an exciting possibility for dental care. But Carter also has a warning. "Actually re-growing the tooth that has been lost with a cavity would be really a huge step forward. But, it's also important that we remember that we shouldn't be getting the cavity in the first place. We're talking about a totally preventable disease."

    A new study, conducted by British company Mindlab International, has found that listening to music at work increases accuracy (精确) and speed, The Telegraph reported.

    Perhaps, some parents disagree with this idea, saying, "Switch off the music and concentrate!" Well, if that's the case with your parents, you might now be able to convince them that you have science on your side.

    The company gave 26 participants（参与者）a series of different tasks for five days in a row, including spell checking, mathematical word problems, data entry, and abstract reasoning. The participants completed these tasks while listening to music or no music at all.

    The results showed that while music was playing, 88% of participants produced their most accurate test results and 81% completed their fastest work. David Lewis, chairman of Mindlab International, told The Telegraph, "Music is a very powerful management tool if you want to increase not only the efficiency of your workforce but also their emotional state... they are going to become more positive about the work."

    However, you may have a list of your favorite songs, but not all kinds of music match all homework. For maths or other subjects involving numbers or attention to detail, you should listen to classical music, the study found. In the study, pop music enabled participants to complete their tasks 58% faster than when listening to no music at all. If you are reviewing your English writing, pop music is the best choice, as it is the best kind for spell checking. It cut mistakes by 14%, compared to listening to no music. After finishing your homework, do you often take time to check your answers? Maybe, some dance music is suitable for you.

    Years ago parents worried their children would learn the truth about Santa Claus(圣诞老人)from others, but now they have a new problem—the Internet.

    A recent study from Hide My Ass! Shows 1 in 8 American parents said the Internet told their children the truth about Santa Claus. 44% of parents thought Google was a danger to this Christmas story, as children searched for Santa and found pages explaining he is not real. About 34 percent of children questioned Santa Claus after seeing ads online for gifts they had asked for in their letters to the North Pole (北极). Sadly，one in three children said their Christmas spirit was dead after reading a post saying Santa wasn't real.

    Before the Internet, the only way children found out their parents bought their gifts was if they were in a bad hiding place. Today, two-thirds of parents never clear their browser (浏览器) history, making it easy for kids to find out the gifts under the tree weren't put there by a happy man and his little helpers.

    To keep Mr. Claus alive, “Keep Believing in Santa”, an organization created by Hide My Ass!, helps kids believe in Santa. Parents receive free software from the organization that monitors all online search results and web pages that could tell kids the truth about the man who lives in the North Pole, by hiding any information that may suggest he doesn't exist.

    However, there is still a higher possibility of the Internet now being the main cause of a child's belief in Santa ending, and it can also result in kids finding out sooner than for those born before the digital age.

    ''With this organization, we wanted to give parents a new tool that would allow them to keep the magic of Christmas and the mystery of Santa for that little bit longer,” Cian  Mckenna-Charley, marketing director at Hide My Ass!.

    A new Magic Bench designed by Disney Research lets you interact (互动) with lovely animated (动画的) character—and no special glasses or earphones are required. Instead, the complete environment-the seat, the sitter and the cartoon characters-is mirrored on a screen opposite the bench making it possible for others to watch the scene unfold.

    How does the illusion work? A camera and sensor catch images and gather depth information about physical objects the bench and the person. And then computer translates them into the 3D animations. Meanwhile sensors of touch built into the bench deliver shaking that is happening at the same time and speed to animated actions on the screen, creating the illusion that the animated figures are occupying real-world space next to the user.

    "Our goal for this project was: hear a character coming, see them enter the space, and feel them sit next to you," said Moshe Mahler, principal digital artist at Disney Research. Unlike the traditional mobile technology, one of whose limitations is that only a single user can see its illusion, the Magic Bench allows groups of people to gather in a single environment and collectively participate in an augmented—reality (扩充实境) experience, all at the same time.

    In a video show, a small cartoon donkey runs into view and kicks the bench, causing sharp sound and making the seated person jump in surprise. Another test shows two people on the bench, reacting as they feel an animated rabbit skip up beside them and jump up and down. When a user passes his hand over the rabbit, a shadow moves across its head, as though it were occupying the same physical space as the person next to it.

    Brian Hamilton's life changed in a prison when he was accompanying his friend, Reverend Robert J. Harris, who often went to local prisons to do his work. During the visit, Hamilton started talking to one of the prisoners and asked what he was going to do when he got out.

    "He said he was going to get a job," Hamilton recalls(回忆). "I thought to myself, wow, that's going to be difficult with a criminal background."

    The conversation made Hamilton consider how prisoners could benefit from entrepreneurship, something he thought about for years. Finally in 2008, 16 years after that initial conversation, Hamilton created Inmates to Entrepreneurs, a nonprofit organization that helps people with criminal backgrounds start their own small businesses. "Harris and I taught our first course at a prison called 'How to Start Your Own Business When You Get Out'," he recalls.

    At the time, Hamilton was building his own company, Sageworks. As Sageworks grew, so did Hamilton's time spent teaching at prisons throughout North Carolina.

    Eventually, Hamilton decided it was time to change his focus to his true passion. In May 2018, he sold his stake(股份) in Sageworks, focusing his commitment on Inmates to Entrepreneurs.

    "Now, anyone is able to access the curriculum, either to become an instructor to go into prisons to teach it or to access it for themselves as a prisoner or part of the general population," Hamilton explains. In addition, he visits middle schools and presents the curriculum to at-risk students as a preventative measure against crime.

    The free curriculum is funded by the recently established Brian Hamilton Foundation, which offers assistance to military members as they adjust to civilian life and provides loans to small businesses. "We're giving prisoners something they can do independent of a system that isn't working for them. If you can let people know that other people care about them, it makes a difference."
