    The Internet has been found a new usage. Increasingly, more and more Americans are having a(an) to become their own doctors, by going online to order home health tests or medical devices, or even self-treat their illnesses with drugs from Internet pharmacies(药店). Some people doctors because of the high cost medical care, especially if they health insurance.

Patients may also fear what they might learn about their health, or they distrust physicians because of in the past. But to become their own doctors can be.

    Every day, more than six million American search the Internet for medical answers. Most of them have no about what they find. In 2002, a survey by the Pew Internet & American Life Project found that 72 percent of those surveyed believe all or most of what they read on health websites. Actually, most of such web sites are only interested in doing business. Of the 169 websites the researchers rated, only 16 scored as "high quality". Recent studies found faulty facts about all sorts of other disorders, causing one research team to  that a large amount of incomplete, inaccurate and even dangerous information exists on the Internet.

    The problem is that most people don't know the safe way to surf the web. "They use a search engine like Google, get 18 trillion choices and start clicking. But that's risky, because almost anybody can put up a site that looks  , so it's hard to know National Cancer Institute.

    For several decades, various types of artificial intelligence kept shocking the world. Robots could {#blank#}1{#/blank#} people in highly competitive games and then quickly destroyed their human competitors.

    AI long ago mastered chess, the Chinese board game Go and even the Rubik's cube, which it managed to solve in just 0. 38 second.

    Now machines have a new game that will allow them to {#blank#}2{#/blank#} humans: Jenga, the popular game in which players {#blank#}3{#/blank#} remove pieces from an increasingly unstable tower of 54 blocks, placing each one on top until the entire structure would {#blank#}4{#/blank#}.

    A newly released video from MIT shows a robot developed by the school's engineers playing the game with surprising accuracy. The machine is equipped with a soft gripper (夹子), a force-sensing wrist and an external camera, allowing the robot to detect the tower's {#blank#}5{#/blank#} the way a human might do

    Unlike in purely recognitive tasks or games such as chess or Go, playing the game of Jenga also requires mastery of physical acts such as pushing, pulling, placing, and arranging pieces. It must {#blank#}6{#/blank#} interactive physical operation, where you have to touch the tower to learn how and when to move blocks.

    Imitating it is rather difficult, so the robot has to learn in the real world, by working with the real Jenga tower. Recently, a relevant research was published in the journal Science Robotics. Researchers say the robot demonstrates that machines can learn how to perform certain tasks through actual touching instead of relying heavily on visual {#blank#}7{#/blank#}. That physical {#blank#}8{#/blank#} is significant, researchers say, because it provides further proof that robots can be used to perform {#blank#}9{#/blank#} tasks, such as separating recyclable objects from landfill trash and assembling consumer products.

    In a cellphone assembly line, the felling of any component is coming from force and touch rather than vision. To become an accomplished Jenga player, the robot did not require as much repetitive practice as you might imagine. Hoping to avoid reconstructing a Jenga tower thousands of times, researchers developed a method that allowed the robot to be trained on about 300 games. Researchers say the robot has already begun facing off against humans, who remain {#blank#}10{#/blank#} players—for now.
