Have you ever run into a careless cell phone user on the street? Perhaps they were busy talking, texting or checking updates on WeChat without looking at what was going on around them. As the number of this new “species” of human has kept rising, they have been given a new name — phubbers（低头族）.

    Recently, a cartoon created by students from China Central Academy of Fine Arts put this group of people under the spotlight. In the short film, phubbers with various social identities(身份) bury themselves in their phones. A doctor plays with his cell phone while letting his patient die, a pretty woman takes selfie in front of a car accident site, and a father loses his child without knowing about it while using his mobile phone. A chain of similar events eventually leads to the destruction of the world.

    Although the ending sounds overstated, the damage phubbing can bring is real.

    Your health is the first to bear the effect and result of it. “Constantly bending your head to check your cell phone could damage your neck,” Guangming Daily quoted doctors as saying. “the neck is like a rope that breaks after long-term stretching.” Also, staring at cell phones for long periods of time will damage your eyesight gradually, according to the report.

    But that's not all. Being a phubber could also damage your social skills and drive you away from your friends and family. At reunions with family or friends, many people tend to stick to their cell phones while others are chatting happily with each other and this creates a strange atmosphere, Qilu Evening News reported.

    It can also cost you your life. There have been lots of reports on phubbers who fell to their death, suffered accidents, and were robbed of their cell phones in broad daylight.

    Stop wasting your time thinking of reasons for your failures and shortcomings. Instead, realize that the seeds of success were planted within you when you were born. Only you have the power to make those seeds grow.

    The seeds, and the power to grow them, are contained in the most awesome machine ever created: the human mind. Success is a choice and not a chance. You were born a winner. You were born rich. You can be a success if only you make the right choice.

    You cannot be successful without first developing your self-esteem (自信心). Your level of self-esteem is always based on the degree of control that you are able to exercise over yourself, and thus over your life. People with low self-esteem are people who do not believe that they have any power, or responsibility for their lives. They are always victims. They are leaves tossed (摇摆) by the winds of chance blown about with any sudden change in the weather.

    You can exercise control over your life only to the degree that you believe you are responsible for everything that happens in your life. Failures think that everything happens by accident and chance. Successful people realize that they are responsible.

    Everything happens as a result of something. If we can identify the cause, we can control the effect. We are responsible for what we choose to think and believe. One generally rises to the level that one expects. We are responsible for setting our expectations. Our success is dependent upon our level of confidence.

    If you associate with positive-thinking people, you are definitely going to achieve success. On the contrary, the opposite happens. We are responsible for finding, planting, and nurturing (培育) the seeds that contain future victory, born from setbacks (挫折).

    In short, in all areas of your life, whether they are financial, physical, emotional, or spiritual, you are responsible. Once you recognize this, accept it, and firmly believe it. You are on the road to success.

    Taxi-booking app Uber agreed to sell its business in China to Didi Chuxing. The two firms had been fierce competitors, but Didi Chuxing had controlled the Chinese market with an 87% share.

    Uber China launched in 2014, but it had failed to make any profit for a long time. Cheng Wei, founder and chief executive of Didi Chuxing, said the two companies had learned a great deal from each other over the past two years in China. He added that the deal would set the mobile transportation industry on a healthier path of growth at a higher level. As part of the deal, Mr. Cheng would join the board of Uber, while Uber chief executive Travis Kalanick would also join Didi's board.

    Uber's China business would own its separate branding while US-based Uber Technologies would hold about 17.5% in the combined company. Didi Chuxing is backed by Chinese Internet giants Tencent and Alibaba.

    Uber had been struggling to break into the Chinese market despite having Chinese search engine Baidu as an investor. Last February, the company admitted it was losing more than $1 billion a year in China. “Funding their Chinese dreams was becoming too expensive for Uber,” Duncan Clark, chairman of Beijing-based consultancy BDA, told the BBC. Travis Kalanick said, “As a businessman, I've learned that being successful is about listening to your head as well as following your heart.”

    The fierce competition had led both companies to spend much more on their journeys. The combination is likely to see fewer such subsidies（补贴）. “One thing to watch carefully is how quickly consumers feel the impact as subsidies are withdrawn.” Mr. Clark added.

    The deal with Didi Chuxing came just days after China had agreed to provide a legal framework for taxi-ordering apps. Both Uber and Didi welcomed the decision. The new rules took effect last November and could, among other things, forbid such platforms to operate below cost.

    Researchers in China and the United States have developed a new cataract(白内障)treatment with cells that has restored vision in babies in a trial and may eventually be used in adults.

    The treatment-by doctors and staff members at the University of California, San Diego School of Medicine and Sichuan and Sun Yat-sen universities in China-was published in March 9 edition of the scientific journal Nature.

    A cataract is a clouding of the normally clear lens(晶体)of an eye. Typical cataract operation involves the removal of the cloudy lens and the insertion of an artificial one. The new operation has been tested in animals and during a small, human trial. It resulted in fewer complications(并发症)than the current harmful operation, and in regrown lenses with superior visual function in all 12 of the baby cataract patients who received the procedure.

    A congenital cataract-lens clouding that occurs at birth or shortly after- is important cause of blindness in children. In the new research, K and Zhang, head of ophthalmic genetics at US San Diego's Shiley Eye Institute, and his colleagues relied on the regrown potential of endogenous(同源的)stem cells.

    According to Zhang, endogenous stem cells are different from other stem cells that are typically grown in a laboratory, transplanted into a patient, and can have risks of immune（免疫的）rejection, infection or cancers. Zhang told CBS News, “We invented a new operation to make a very small opening at the side of a cataractous lens bag, remove the cataract inside, allow the opening to heal, and promote potential lens stem cells to regrow an entirely new lens with vision.”

    The human trial involved 12 babies under the age of 2 who were treated with the new method, while 25 babies received the standard operation care. The latter group experienced a higher incidence of post-operation danger, early- onset eye high blood pressure and increased lens clouding. The scientists reported fewer complications and faster healing among the 12 babies who has the new procedure.

    After decades of cat-and-mouse between athletes and the word anti-doping agency (WADA), athletes found what they must have believed to be the ultimate (终极的) doping agent: their own blood. To enhance athletic performance with your own blood, you draw your blood and store it in a freezer. Your body compensates by creating more blood. Then, months later, just before a competition, you can re-inject (注射) the old blood for a boost. As the red-blood-cell count goes up, so does an athlete's ability to absorb oxygen. The more oxygen you get with each breath, the more energy your body is able to bum and the better you are able to perform.

    Although the enhancement is small compared to actual drugs, it can be the difference between a gold medal and a silver medal. Best of all, "extra blood" was never something WADA tested for.

    But WADA wasn't going to sit by and be fooled. What it came up with in response might be a solution to stop doping once and for all: an athlete biological passport (ABP). The idea is to record some biological features of an athlete through testing done at regular intervals. The biological passport's partial implementation (实施)—recording blood and steroid levels—began in January 2014.

    When all necessary biological features are finally combined, WADA will no longer need to worry about finding new methods to detect a drug. It will only have to detect (检测) resulting changes in the body. In the case of blood doping, if the athlete's normal red-blood-cell count is, say, 47%, but then is found to be 51% after a competition, cheating may have been involved.

    WADA is confident that the biological passport could even prevent genetic changes—the ultimate, ever-lasting enhancement—which are surely coming next. If an athlete inserts a performance enhancing gene, it will probably leave detectable changes in the body, that would differ from the athlete's feature in the biological passport.

    As the international demand for narrative(叙事的) film/TV content continues to increase with popular streaming services like Netflix and others the two questions then come: will the coming generations receive most of their entertainment through visual means rather than through the written word and will such an increase of narrative film/ TV reduce the importance of reading?

    Growing examples of this trend include the diminishment(减少) of fiction in the common core (核心的)curriculum, the ever－rising culture of computer games, the wave of streaming services of wide international reach, and movies filled with special effects made for children and teenagers. Nor must we ignore the economic dangers that lie ahead for the written word. The narrative film industry is a moneymaker that dwarfs(使相形见绌) the publishing industry.

    The other underlying question, of course, is "does it really matter if the written word bows to the world of film/TV?" From my point of view, any diminishment of fiction delivered by words is a loss for mankind.

    There is no greater human feature than the imagination. It lies at the very soul of the human species. It is the brain's most powerful engine. It is the essential muscle of life and like all muscles it must be exercised and strengthened.

    Writing and reading are the principal tools that inspire, create and empower our imagination. Anything that diminishes that power is the enemy of mankind.

    It should be known that I am not opposed to new media and technological advances. Instead, I have always felt it necessary to adapt to advancing technology. In fact, a number of my novels are in various stages of development for film, TV, and live stage productions. My hope is that the written word will only stand to be complemented(补充)by its visual counterparts(对应物), not pushed to the edge of extinction.

    Of course, there are those who will present arguments for the superiority of the moving image over the written word. Each has its place. My argument is for finding the right balance between it and the moving image.
