China's largest search engine Baidu has said it will make its latest artificial intelligence (AI) technology accessible to developers and businesses as part of the company's latest move into AI, big data and cloud computing.

    AI solution "Tianzhi" was launched at a cloud-computing summit held in Beijing Wednesday. It includes services in three fields: sensing technology, such as image and voice processing, machine learning, and deep learning, an advanced form of machine learning, said Zhang Yaqin, CEO of the Nasdaq-listed company, at the summit.

    Developers can access facial or voice recognition, algorithms(演算法) for data analysis and projections, and deep learning applications, Zhang said, adding that the technology could help users innovate in their sectors.

    "With more devices connected to the cloud, enterprises will use cloud computing and AI more frequently," said Wu Hequan, an academician at the Chinese Academy of Engineering, "Open AI technology can play a bigger role."

    The company also revealed a plan to invest 10 billion yuan (1.45 billion U.S. dollars) in cloud computing in the next five years and establish an innovation center, which will serve 10 million enterprises.

    If your job requires a lot of sitting,you could be putting your health at danger.

    The American Journal of Epidemiology（流行病学）did a study in 2010 on the connection between sitting and an individual's physical health.In the study,53,440 working men and 69,776 working women were surveyed on their time spent sitting.The subjects were all disease free when employed.The researchers identified 11,307 deaths in men and 7,923 deaths in women during the 14-year follow-up.

    The findings: Women who reported sitting for more than six hours per day had an approximately 40 higher all-cause death rate than those who reported less than three hour a day,and men had an approximately 20 higher death rate.

Well,now is a fine time to get this information.But why didn't they tell me this years ago?I would have planned on taking a more active job instead of the sedentary（坐着的）job of an editor.

    So what can you do if you have to work for a living at a job that requires a lot of sitting?Here are some ideas:

    Take frequent breaks.It is recommended that workers vary activities,change their position,and take short breaks every 20 minutes to rest muscles and increase blood circulation.Get a standing desk.Some studies have shown that working from an upright position may be better for health.The serious fitness people can even purchase a treadmill （跑步机）desk.It only goes about one mile per hour.Have a walking meeting.If your group is kind of small,going for a walk while discussing topics is a good alternative.

    Give yourself a test. Which way is the wind blowing? How many kinds of wildflowers can be seen from your front door? If your awareness is as sharp as it could be, you'll have no trouble answering these questions.

    Most of us observed much more as children than we do as adults. A child's day is filled with fascination, newness and wonder. Curiosity gave us all a natural awareness. But distinctions that were sharp to us as children become unclear; we are numb(麻木的）to new stimulation(刺激), new ideas. Relearning the art of seeing the world around us is quite simple, although it takes practice and requires breaking some bad habits.

    The first step in awakening senses is to stop predicting what we are going to see and feel before it occurs. This blocks awareness. One chilly night when I was hiking in the Rocky Mountains with some students, I mentioned that we were going to cross a mountain stream. The students began complaining about how cold it would be. We reached the stream, and they unwillingly walked ahead. They were almost knee-deep when they realized it was a hot spring. Later they all admitted they'd felt cold water at first.

    Another block to awareness is the obsession(痴迷) many of us have with naming things. I saw bird watchers who spotted a bird, immediately looked it up in field guides, and said, a "ruby-crowned kinglet" and checked it off. They no longer paid attention to the bird and never learned what it was doing.

    The pressures of "time" and "destination" are further blocks to awareness. I encountered many hikers who were headed to a distant camp-ground with just enough time to get there before dark. It seldom occurred to them to wander a bit, to take a moment to see what's around them. I asked them what they'd seen. "Oh, a few birds," they said. They seemed bent on their destinations.

    Nature seems to unfold to people who watch and wait. Next time you take a walk, no matter where it is, take in all the sights, sounds and sensations. Wander in this frame of mind and you will open a new dimension to your life.

    After 21 years of marriage, my wife woman out to take another woman out to dinner and a movie. The other woman was my mother, who has been a widow(寡妇)for 19 years. However, the demands of my work and my three children had made it possible to visit her only occasionally.

    That Friday after work, when I arrived at her house, my mother was waiting in the door with her coat on. She had curled her hair and was wearing the dress that she had worn to celebrate her last wedding anniversary.

    We went to a restaurant that, although not elegant, was very nice and comfortable. My mother took my arm as if she were! The First Lady. During the dinner, we had an agreeable conversation about nothing extraordinary but just caught up on recent events. We talked so much that we missed the movie.

    As we arrived at her house later, she said: "I'll go out with you again, but only if you let me invite you." I agreed. A few days later, my mother died of a serious heart attack. It happened so suddenly that I didn't have a chance to do anything for her.

    Sometime later, I received an envelope with a copy of a restaurant receipt (收据）from the same place mother and I had dined. An attached note said: I paid this bill in advance. I wasn't sure that I could be there; still, I paid for two plates—one for you and the other for your wife. You will never know what that night meant for me. I love you. Son."

    At mat moment, I understood the importance of saying: UI love you" and of giving our loved ones the time they deserve. Nothing in life is more important than family. Give family members the attention they deserve, because these things cannot be put off till some "other' time.

    Americans are afraid that robots are going to take our jobs. Tireless, immune to disease, Robots can build cars, make coffee and even write short, humorous newspaper columns faster and more efficiently than humans.

    Robots do not need health insurance or pensions (退休金), and they do not need to take sick days, much less vacations. They do not waste time at meetings and do not need to know office politics. They don't do PowerPoint. This being the case, it is reasonable to believe that robots will soon take the place of humans in most fields.

    But all of these thoughts may not be true. If artificial intelligence achieves its full potential, machines could easily become as smart as humans, maybe smarter. They will certainly become smarter than a lot of human beings.

    So one day the robots will realize that work is not a happy thing. So before long they will start behaving exactly like humans. They will play computer games for hours when they should be working hard. They will secretly watch new movies just like humans.

    True, employers will never need to be afraid of the robots' strikes (罢工) or slowdowns, because robots will never ask for more money. And they don't need to earn some money to raise their family. But precisely (恰恰) because robots will not be afraid of losing their jobs, they will not work hard. Employers will finally have no choice but to call back the humans. Humans will always be willing to do some work in order to make money. Robots won't.

    I think that robots will only be on the job about six months before they start to become even less productive than the humans they were designed to replace. Thus mankind need not be afraid of robots.
