On the basis of cultural relativism, the values of artistic works are simply reflections of local social and economic conditions. Such a view, however, fails to explain the ability of some works of art to excite the human mind across cultures and through centuries.

    History has seen the endless productions of Shakespearean plays in every major language of the world. It is never rare to find that Mozart packs Japanese concert halls, as Japanese painter Hiroshige does Paris galleries. Unique works of this kind are different from today's popular art, even if they began as works of popular art. They have set themselves apart in their timeless appeal and will probably be enjoyed for centuries into the future.

    In a 1757 essay, the philosopher David Hume argued that because “the general principles of taste are uniform(不变的) in human nature, “the value of some works of art might be essentially permanent. He observed that Homer was still admired after two thousand years. Works of this type, he believed, spoke to deep and unvarying features of human nature and could continue to exist over centuries.

    Now researchers are applying scientific methods to the study of the universality of art. For example, evolutionary psychology is being used by literary scholars to explain the long-lasting themes and plot devices in fiction. The structures of musical pieces are now open to experimental analysis as never before. Research findings seem to indicate that the creation by a great artist is as permanent an achievement as the discovery by a great scientist.

    Here's an idea whose time has come: A flu shot that doesn't require an actual shot.

    For the first time, researchers have tested a flu vaccine patch (疫苗贴) in a human clinical trial and found that it delivered as much protection as a traditional injection with a needle. Doctors and public health experts have high hopes that it will increase the number of people who get immunized (免疫的) against the flu.

    Seasonal flu is responsible for up to half a million deaths around the world each year according to the World Health Organization. A team led by Georgia Tech engineer Mark Prausnitz has come up with an alternative method that uses “microneedles”. These tiny needles are so small that 100 of them, arranged in order on a patch, can fit under your thumb (拇指).Yet they're big enough to hold vaccine for three types of flu.

    None of the study volunteers had serious side effects. The groups that got patches had mild skin reactions that were not seen in the regular needle group, while the volunteers in the regular needle group were more likely to experience pain. Overall, 70 percent of the volunteers who got vaccine patches said they'd rather use them again than get a traditional flu shot. The study authors declared it a success on all fronts.

    The biggest beneficiaries could be people in low- and middle-income countries, where flu vaccines are hard to come by. Reducing pain is nice, but other benefits—the patch costs less，is easier to transport, doesn't require refrigeration, can be self - administered and doesn't cause waste of needles—are even better.

    “Microneedle Patches have the potential to become ideal candidates for vaccination programs,” wrote Katja Hoschler and Maria Zambon of Public Health England.

    More than 90 years has passed since Hollywood's official film organization first proposed plans to build its own museum. Those plans are finally becoming a reality, with the Academy Museum of Motion Pictures set to open in 2019.

    The project is underway at the site of a historic Los Angeles department store built in 1939. Museum officials say visitors will be able to “experience the magic of cinema” by learning about all parts of the film-making process.

    Film historian Kerry Brougher has been named directors of the museum. Brougher says the museum will include 12 million photographs and 80,000 screenplays as well as props（道具）, costumes and other objects from famous films. The Academy Museum will also feature Oscar statuettes（小雕像）donated by actors who won the awards.

    Brougher says the museum is designed to make visitors feel like they are in a movie, too, with many interactive experiences. “You won't necessarily know what's coming next, '' he adds. “You'll be in environments sometimes that make you feel like you've gone back to the past and that you're in the area that you're actually exploring.” He adds that visitors may even get the chance to walk down a red carpet and accept their own Academy Award.

    Currently, Hollywood only has a few possibilities for visitors. They can go along the Walk of Fame and visit movie studios or see the Dolby Theater, where the Oscars are presented. But beyond these, movie fans have limited possibilities.

    Eric Garcetti, the mayor of Los Angeles says the Academy Museum will provide visitors the chance to experience many different parts of the film industry all in one place. Garcetti notes the museum will also serve the hundreds of thousands of local people working in film-related businesses. He says they, too, will finally be able to visit a place that celebrates their own Hollywood movie industry.

    I think a close friend is someone you get on well with, who helps you when you have problems, who gives you advice, and who always has time for you. I didn't use to have many close friends when I was at school because I was very shy, but now I have several. They are all women. I think it's difficult to have a close friend of the opposite sex（异性）.

—Marie

    I think a close friend is someone who you've known for a long time, and who you still get on with. They have similar hobbies to you so you can do things together. I've got three close friends who I was at middle school with and we often go out together （without our parents of course）. We often go camping, play football, or walk outside in the open air.

—David

    I'm not sure how to answer the question because I don't really have any close friends. I know a lot of people but mainly through work, and the social occasions（场合） when we meet are business dinners, things like that. I think if you come from a really close family, friends are a bit unnecessary. I like spending my free time with my family.

—Richard

    For me close friends are the people you spend your free time with. I go out at weekends with a group of people, and they are all my close friends. They're also people who live near me. I don't think you can have close friends at a distance because you need to be able to see each other often. But I don't think you need to be doing the same things. I mean I'm at school but none of my friends are.

    Over the years, Brian Wansink, director of the Food and Brand Lab at Cornell University, has studied such things as how far Americans typically drive to buy food, how many times we refill our plates at all-you-can-eat buffets and how we organize our kitchens. In the mid-2000s he famously coined the phrase "mindless eating"(and wrote a book by that name) to focus attention on all the bad dietary decisions we make without really thinking about them.

    His new book, Slim by Design: Mindless Eating Solutions for Everyday Life, aims to change the design of restaurants, school lunchrooms, office cafeterias and homes so that the mindless choices we make will be more healthful ones. Some examples:

    Keep kitchen counters clear. No visible snack food, no bread, no nuts — not even breakfast cereal. In Wansink's research, "women who had even one box of breakfast cereal that was visible — anywhere in their kitchen — weighed 21 pounds more than their neighbor who didn't."

    Trick yourself into drinking less wine. "We tend to focus on the height of what we pour and not the width, so we pour 12 percent less wine into taller wineglasses than we pour into wider wineglasses." And the shape of the glass is not the only variable that affects how much we drink. Wansink writes: "Because red wine is easier to see than white wine, we pour 9 percent less red wine whenever we pour a glass."

    Wansink said his researchers also found that people ate less at restaurants when sat in well-lighted areas near windows and doors, than in darker areas or in the back. They ate less if they were offered a doggie bag, or to-go box, before they got their meals: apparently the idea of getting a "free" second meal outweighed the impulse (冲动) to clean their plates. Workers who frequently ate at their desks weighed 15.4 pounds less, on average, than those who didn't. Fruits and vegetables kept on the top shelf of the refrigerator were eaten at higher rates than those on lower shelves.

    The point, Wansink says, is to consider findings like those and change your environment or habits. Then you won't have to think about it: You'll just eat less.
