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(同伴) 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.

    A recent study by Citi Retail Services found that a growing number of people are embracing digital wallets or e-wallets, due in large part to their convenience and ease of use.

    E-wallets have been called the future of real-world payment technology.With major players like Alipay,WeChat and Apple Pay becoming popular,it seems to be a safe bet that a change in consumer payment technology is coming soon.

    CNN reporter Paul Ripley experienced a day in Beijing without his wallet."In China's largest cities, you can definitely survive without carrying a pocket full of cash and credit cards-as long as you've got your smartphone."He paid for breakfast by scanning a QR code on the window of a hole-in-the-wall restaurant.All he had to do was to enter a password and the transaction was complete.

    Unlike the situations in the US and other countries,"China doesn't have a really money-making credit card system, so Chinese people just skipped credit cards and went straight to mobile payments."Gu Yu,co-founder of the new payment app Mileslife,told CNN.He also pointed out the advantages of mobile payments."No coins or bills that can be lost or stolen. electronic receipts, the ease of keeping rack of spending-and of course,no wallet taking up space."he said.

    However, if we want to make e-wallets a mainstream trend a lot of things will have to change over the coming years.Perhaps one of the most important things that need to be changed is how people regard e-wallets.Linda Barrabee,research director for NPD Connected Intelligence, said in a statement."In order to promote on-the-go consumer transactions and commerce, wireless carriers, credit card companies, and e-commerce companies need to make sure the process is convenient,simple,and secure for consumers."

    The best festivals in Europe

    Whether they're in the countryside or a post-industrial landscape, Europe's yearly festival calendar means new events, old favourites, crazy people and great charm.

    OFF Festival, Poland

    A small festival in Katowice in south-west Poland, OFF has, over the past 10 years, built an international audience thanks to a challenging and interesting mix of acts. This year's selection focuses on female artists: singer-songwriters Feist and PJ Harvey headline, while Swedish pop singer Anna von Hausswolff and classical composer turned electronic producer Anna Meredith are also on the bill. Meanwhile, the experimental poetry and performance project by Moor Mother will undoubtedly be an unmissable show.

    Melt, Germany

    What would Melt be without its “sleepless stage”--a non-stop music marathon that runs from Saturday morning to midday on Monday? The German festival for those who love an all-hours party takes place in Ferropolis, Gra fenhainichen. This year, the festival celebrates its 20th anniversary, bringing 20,000 people together.

    Charity is simple in theory：A heart warms, a hand reaches out. In practice, though, charity can become a troubled mix of motives and consequences. Giving can be driven by guilt, duty, praise, or perhaps the hope that giving will somehow make up for past cruelty or ignorance. Too little charity is far less than valuable. Too much can cause dependence which makes the receiver continuously ask for more.

    Giving from the heart is good. But critics have long worried about misdirected charity that does more harm than good. In his 2012 book, "Harmful Charity: How Churches and Charities Hurt Those They Help（And How to Solve the Problem）, "Robert Lupton, an experienced social worker of 40 years of community work in inner-city Atlanta, argues that charity must not do for the poor what they can do for themselves.

    Due to emergencies such as natural disasters, the afterward financial aid is greatly welcome. Mr. Lupton advocates it should focus on the development of self-supporting. The task can be carried out via, for instance, offering microloans, hiring local builders and suppliers, and trying to found self-supported, locally owned and operated enterprises. What seldom works, he argues, are untargeted handouts from far-off providers and the sudden arrival of inexperienced volunteer-tourists hoping to earn personal reputation by digging wells or mending roofs that locals are perfectly able to take care of themselves.

    Getting charity right isn't easy. But from money raising to the boom in volunteering among Millennials（千禧一代）, from the increasing worldwide willingness to give to the efforts by charity organizations to become more effective and fruitful, there is strong evidence that human beings' ability of taking care of others is growing along with their ability to help without harming.

    Charity can be as simple as holding the door for a stranger and as complex as a global campaign to get rid of malaria（疟疾）.Charity works best when it returns the weak to strength, when it helps a small town shaken by a heavy earthquake get back on its feet. A successful charity is one that eventually is no longer needed.

    This may be music to your ears. Researchers P. Jason Rentfrow and Samuel Gosling gave 3,500 people a personality（人格、个性）quiz. "We found that the musical styles people like are closely linked to their personalities," Gosling says.

    RAP/HIP-HOP

    Known for their quick speech, some rappers can say more than 700 syllables（音节）a minute! If you like rap/hip-hop, you are energetic and have a way with words. You put a fresh spin on things, whether it's new moves on the dance floor or your hip style.

    CLASSICAL

    In the 18th century, classical musicians were like rock stars. Beethoven and Mozart, for example, played in crowded concert halls. If you like classical, you are open to new ideas and like debating with friends. Creative and imaginative, you can easily spend many hours scrapbooking（剪贴）, writing or painting.

    COUNTRY

    Country music came from the folk songs of English, Scottish, and Irish settlers of the southeastern United States. If you like country, you express your opinions well, which makes you the ideal class president or team captain. Traditional and loyal, you enjoy spending time with your family.

    POP

    Pop music is designed to attract almost everyone, and it does. Each year, the industry brings in about 30 billion dollars! If you like pop, you are attractive to your friends. You can make big things happen, like planning for a huge party or inspiring your team to victory.

    ROCK/ALTERNATIVE

    In the 1950s, rock music created a brand-new culture. Teenagers, for the first time, had an identity separate from adults and children. If you like rock/alternative, you are a risk-taker who never accepts no for an answer. You rise to any challenge, like doing very well in a big exam or landing the lead in the school play.

    If these personality profiles（人格剖析）don't match you, that's OK. These are just for fun.

    There are billions of people on this planet, and many of us love to eat meat. In 2018 alone, the average American will consume more than 100 kgs of red meat, according to a report from the US Department of Agriculture (USDA). At the same time, the environmental impact caused by meat consumption – waste, animal treatment, health issues and even the greenhouse gas effects – has given rise to a number of startups (新兴企业) looking for ways to fill our growing demand for meat. But can the demand be filled in a sustainable and affordable way?

    A bunch of companies are not only optimistic but are working to make this happen sooner. All of these companies harvest cells from animals and grow them in a lab. For example, San Francisco-based Memphis Meats is developing cell-based meats in its laboratories by manufacturing fat and muscle cells without requiring any animals. And don't worry if you're not a meat lover. Startups such as Jet Eat, which is based in Israel, are working on food products grown in labs that are plant based and produce meats using natural ingredients while still maintaining flavor, consistency and the "overall sensory experience".

    As you can imagine, there are plenty of hurdles facing the industry. Educating the public is a big one. Another controversial issue is the labelling of the products. Meat industry trade groups have been pressing the USDA to more strictly regulate alternative meats, labeled as "imitation products".

    Many of us have concerns about the challenges facing future generations as our global population swells and the earth's natural resources shrink. The good news is that there are plenty of companies around the world—like those producing lab-grown meats - who are working to solve some of these problems and make a few bucks in the process. Nothing wrong with that.
