What makes people happier: money or having happy friends and neighbors? Researchers from Harvard University and the University of California, San Diego, have found an answer as part of a study.

    The new study found that friends of happy people had a greater chance of being happy themselves. And the smaller the physical distance between friends, the larger the effect they had on each other’s happiness. For example, a person was twenty percent more likely to feel happy if a friend living within one and a half kilometers was also happy. Having a happy neighbor who lived next door increased an individual’s chance of being happy by thirty-four percent. The effects of friends’ happiness lasted for up to a year.

    The researchers found that happiness is really contagious. Sadness also spread among friends, but not as much as happiness. People removed by as much as three degrees of separation still had an effect on a person’s happiness. Three degrees of separation means the friend of a friend of a friend. The study showed that having an extra five thousand dollars increased a person’s chances of becoming happier by about two percent. But the researchers found that the influence of a friend of a friend of a friend can be greater than that.

    Another finding is that people who are married or work together do not have as much of an effect on happiness as friends do. Earlier studies by the two researchers described the effects of social networks on obesity and efforts to stop smoking. The new study shows that happiness spreads through social networks like an emotional virus—a virus people would be happy to catch.

A chocolate printer that allows sweet lovers to create 3D desserts by themselves is to go on sale at a cost of 2,500 pounds.
The machine squirts (喷射) out chocolate and, via computer instructions, allows the user to build any shape they like out of the food. But makers Choc Edge have missed the Easter rush. Even so, they hope the printer will be snapped up by retailers (零售商) immediately they come to the market. Britain’s biggest chocolatiers Thornton’s have already said they are interested. Because of the high cost, however, few individuals are likely to buy one. But the devicecould one day allow people to design their own 3D objects after submitting their designs on a website. Dr Hao, founder of Choc Edge came up with a prototype (原型) last year and has only just perfected it so that it can now go on sale. “We’ve improved and simplified the machine, so now it is really easy to use,” he told the BBC. “You just need to melt some chocolate, fill a syringe (注射器) that is stored in the printer, and get creative printing of your chocolate.”     
3D printing is a technology where a three dimensional object is created by building up successive layers of material. The technology is already used in industry to produce plastic and metal products, but this is the first time the principles have been applied to chocolate. The research has presented many challenges. Chocolate is not an easy material to work with because it requires accurate heating and cooling cycles. Dr Hao said, “What makes this technology special is that users will be able to design and make their own products. From reproducing the shape of a child’s favourite toy to a friend’s face, the possibilities are endless. It could be developed to help consumers design many products from different materials, but we’ve started with chocolate as it is easily available, low cost and harmless.” “There is also no wastage as any spoilage (损坏物) can be eaten.” Dr Hao added, “Eventually we may see many mass-produced products replaced by unique designs created by the customer.”
EPSRC chief executive Professor Dave Delpy said, “This is a good example of how creative research can be applied to create new manufacturing and retail ideas. By combining developments in engineering with the commercial potential of the digital economy，We can see the new market prospect (前景)—creating new jobs and, in this case, the chocolate printer is called sweet business opportunities.”

If a friend asks you to describe the new organization you have joined, it is highly likely that you will begin to describe the culture of the organization. You might say that the office appears friendly; your peers are approachable, no one can fill your work hours as you like, and the new firm has a pleasant“feel”to it.

When I was a baby, I entertained you and made you laugh．Whenever I was "bad" , you'd shake your finger at me and ask : " How could you?"—but then you'd give up, and roll me over for a belly scratch and I believed that life could not be any more perfect．

My housetraining was a long process, because you were terribly busy, but we worked on that together．We went for long walks, runs in the park and car rides．We stopped for ice cream．I took long naps in the sun waiting for you to come home at the end of the day．

Gradually, you began spending more time at work and on your career, and more time searching for a human mate．Eventually, you fell in love．She, now your wife, is riot a dog person, but I still welcomed her into our home．I was happy because you were happy．Then the human babies came along and I shared your excitement, I was fascinated by their pinkness, how they smelled, and I wanted to mother them too．Your wife was afraid I would bite them．But nevertheless, as they began to grow, I became their friend．

Now, you have a new job in another city and you and they will be moving to an apartment that does not allow pets．You've made the right decision for your "family" , but there was a time when I was your only family．

I was excited about the car ride until we arrived at the dog pound．It smelled of dogs and cats, of fear, of hopelessness．You filled out the paperwork and said:"I know you will find a good home for her．" They shrugged and gave you a pained look．The children were in tears as they waved me goodbye．And "How could you?" were the only three words that swept over my mind．

Is it better to live with hope or without hope? At first, whenever anyone passed my pen, I rushed to the front, hoping it was you, that you had changed your mind and that this was all a bad dream．

My beloved master, I will think of you and wait for you forever．I hope you receive more faithfulness from your family than you showed to me．
