A purple tomato genetically engineered to contain nutrients more commonly seen in dark berries helped cancer in mice, British researchers said on Sunday. The finding, published in the journal Nature Biotechnology, bolsters the idea that plants can be genetically modified(changed) to make people healthier.
Cancer-prone mice fed the modified fruit lived significantly longer than animals fed a standard diet with and without regular tomatoes, Cathie Martin and colleagues at
the government-funded John Innes Center in Britain reported. “The effect was much bigger than we had expected.” said Martin, a plant biologist.
The study focused on anthocyanins，a type of antioxidant found in berries such as blackberries and blackcurrants that have been shown to lower risk of cancer, heart diseases and some neurological diseases. While an easy way to improve health, many people don’t eat enough of these fruits, the researchers said. Using genes from the snapdragon flower, the researchers discovered they could get the tomatoes to make anthocyanins---- turning the tomato purple in the process.
Mice genetically engineered to develop cancer lived an average of 182 days when they were fed the purple tomatoes, compared to 142 days for animals on the standard diet. “It is greatly encouraging to believe that by changing diet, or specific components in the diet. You can improve health in animals and possibly humans.” Martin said in a telephone interview.
The researchers warned that trials in humans are a long way off and the next step is to investigate( look into) how the antioxidants actually affect the tumors to promote better health. But the findings do support the formal research suggesting that people can significantly improve their health by making simple changes to the daily diet, other researchers said.
“It’s exciting to see new techniques that could potentially make healthy foods even better for us.” said Doctor Lara Bennett, science information office at Cancer Research UK. “ But it is too early to say whether anthocyanins obtained through diet could help to reduce the risk of cancer.”

All parents know that one of their most important tasks is to prepare their children for an independent life, but any parent can tell you that it’s hard to let go of your children. That balance between keeping your children safe and allowing them to learn from their own mistakes can be heartbreaking. Years of experience means that parents often do know best, but on the other hand the young, being less bound by tradition, are often more creative, more able to find new solutions to old problems. Revolutions are led by the young.

Good teachers make the growth of critical thinking (批判性思维) easier in their students, only to find that this lead to a questioning of the teachers’ basic beliefs. Schools encourage parents to become involved, but are often embarrassed when parents have doubts about some of the educational methods being used. Governments encourage unimportant groups to empower themselves in order to participate fully in the development process. And they are often surprised when the new leaders of these groups turn around and attack the policies or decisions of that same government. However, the rebellious (叛逆的) young and the newly unimportant groups are important in social development. They are not necessarily representatives of those they want to represent in their demands, but their voices must be heard.

Good parents know that just forbidding (禁止) particular behaviors does not prevent their children from finding ways to engage in these forbidden activities. Indeed, sometimes the forbidden fruit is more inviting, just because it is not accepted by authority. Parents must work with their children to educate them on the facts, know as much as possible about the lives of their children, provide a good example, encourage more wholesome activities but also support their children when they don’t follow what is expected of them. But the most important point is that they also need to learn how to let go.

A purple tomato genetically engineered to contain nutrients more commonly seen in dark berries helped cancer in mice, British researchers said on Sunday. The finding, published in the journal Nature Biotechnology, bolsters the idea that plants can be genetically modified(changed) to make people healthier.

Cancer-prone mice fed the modified fruit lived significantly longer than animals fed a standard diet with and without regular tomatoes, Cathie Martin and colleagues at

the government-funded John Innes Center in Britain reported. “The effect was much bigger than we had expected.” said Martin, a plant biologist.

The study focused on anthocyanins，a type of antioxidant found in berries such as blackberries and blackcurrants that have been shown to lower risk of cancer, heart diseases and some neurological diseases.

Miss Gu, a news worker, has to take her mobile phone with her all the time so as not to miss any calls from her office or readers. Gradually, she started to experience a great “panic” about her mobile phone. “Every night when I’m about to fall asleep, I often wake up with a start, feeling that my phone is ringing. Although I’m sure that I have turned it off, I still feel that it is ringing, clearly.”
The above phenomenon is what we call “mobile-phone acouasm (幻听)”. The mobile phone has now become a “new organ” in a white collar’s daily life, and “mobile-phone acouasm” has become a common phenomenon among office workers.
According to a report of China Youth Daily, “mobile-phone acouasm ” most likely results from people’s dependency on hi-tech products. It is associated with certain professions, such as salesmen, consultants and journalists. They use mobile phones almost continuously.
Constantly being in the “stand-by” mode, the strong psychological tension gives them acouasm. Meanwhile, a large number of this year’s graduates are joining the family of acouasm suffers due to the hard job-hunting experience.
“You know that the rings are not from your phone, but you always take it out and have a look. This is subconscious (潜意识) from your body sending you a signal, telling you that you must take a break to reduce your pressure,” Professor Sun Li from Huadong Normal University explains.
There are many ways to solve the problem. The professor says that the key is to deal with pressure from work. “This is just a kind of self-protection”; the most important thing is to find out the source of your pressure. And then take part in some activities that are not related to your work. You can do anything that can relax your body and mind.

Jones worked so hard that made the sparks fly from his hammer．The son of Mr．Smith, a rich neighbor, used to come to see the blacksmith and he would enjoy himself watching how the tradesman worked．"Why don't you try your hand to learn to make shoe tacks?" said the blacksmith．"Who knows, one day, it may be of use to you." The lazy boy began to see what he could do．But after a little practice he found that he was becoming very skilled and soon he was making some of the finest tacks.

Old Mr．Smith died and the son on account of the war lost all his goods．He had to leave home and was forced to take up residence in another country．It so happened that in this village there were numerous shoemakers who were spending a lot of money to buy tacks for their shoes and even at times when they paid high prices they were not always able to get what they wanted, because in that part of the country there was a high demand for soldiers' shoes.

Young Smith, who was finding it difficult to earn his daily bread, remembered that he had learned the art of making tacks and had the sudden idea of making a bargain with the shoemakers．He told them that he would make the tacks if they would help to get him settled in his workshop．The shoemakers were only too glad of the offer．"How funny it seems," he used to say, "even making tacks can bring a fortune．My trade is more useful to me than were all my former riches."
