Scientists are using robots to study the health of waters in and around Venice, Italy. The robots are designed to act like fish, other underwater creatures and plants. The scientists are working with several universities and research centers as part of a group called subCULTron. The European Union gives money to the project as part of its Horizon 2020 program whose aim is to take great ideas from the lab to the market and support science and innovation (创新) in Europe. The scientists want to use the artificial intelligence of the robots to help humans understand what is happening under the water of the Venice lagoon (潟湖).

    SubCULTron, a collective artificial intelligence project, plans to create the biggest shoal (鱼群) of robot fish in the world. The project's aim is to improve knowledge of the seabed and try to turn human abilities into hi-tech items.

    Alexandre Campo, a computer scientist, says the scientists have looked at the way animals learn to work in groups to understand how robots can learn to work together. The subCULTron project wants its robots to learn to work together so they can watch out for changes and new problems in the water.

    One problem the researchers had in the beginning was how the robots would communicate with each other. Wi-Fi and GPS equipment don't work underwater. Instead，the robots can use sonar (声呐) and an electric field.

    Another problem was charging batteries. The robots come up to the water's surface and stay near a boat or a power station to charge without any electrical cables. Besides, how to be water- proof, especially for some key pads of the robots, was really tough. Fortunately, a special mixture has been created to be pinned on the robot, which successfully stands the test of water.

    The health state of the lagoon is pretty good. There are no industrial polluters, and the city now has a modem sewer (污水管) system. It's not like before when all the waste flushed directly into the water. The robots in Venice will continue their work until 2019. The subCULTron project hopes they develop into “an artificial society underneath the water surface” that serves “a human society above the water”.

    Emma and Ryan, a married couple, were driving to a friend's house when Emma turned to Ryan and asked, “Would you like to stop for lunch?”

    Ryan replied. “No, I'm not hungry yet,” and continued driving. Meanwhile, Emma sat quietly fuming (十分恼火)in the passenger seat. Ryan could not understand why Emma was unhappy. He had thought she was asking if he was hungry, but in reality, Emma was telling him that she was hungry and wanted to stop for lunch.

    Misunderstandings like this often occur between men and women, even among people from the same culture. Deborah Tannen, professor of linguistics at Georgetown University in the United States, has studied conversational rules.

    In Emma and Ryan's situation, Emma was making a request in the form of a question. Her style of talking is common for women. She needed Ryan to agree they were both hungry. So, Emma asked Ryan what he wanted. She was really telling Ryan what she wanted; however, Ryan did not understand this. If he had been hungry, he would have said something more direct, such as, “I'm hungry. Let's have lunch.”

    Tannen believes that most women grow up in a world where talk is used to express feelings. However, most men are raised differently and they tend to keep their feelings to themselves.

    Tannen says, for men, talk is often used as a situation used outside the home to gain respect, to entertain and get attention , or to exchange information. This is why men communicate by making each other laugh, or talking about sport and work. These men do not always feel it is necessary to talk to feel close or to express their feelings. Women, on the other hand, are encouraged to speak about their feelings since this is a way to build relationships.

    Rain beat against the window, matching my mood. I should have known that my new job at the hospital was too good to be true. Throughout the day, rumors (传言) warned that the newest employee from each department would be laid off. I was the newest one in the training department.

    My boss appeared. “You probably know we're cutting back,” he said. “Administration wants us to offer outplacement classes to help those employees find other jobs, showing them how to act in an interview, for example.” “Fine,” I answered unwillingly, not knowing what else to say.

    I decided to go home early that day. In the hall, I met the lady who brought us cookies every Friday. She was a little woman with gray hair. Only her head and the top of her green apron were visible over the cart (小车) loaded with cleaning supplies. At least she had a job!

    At the final meeting, laid-off workers formed a line at the door. A colleague whispered, “I can't believe our Cookie Lady is being laid off. We'll miss her as much as we'll miss her cookies.” When the colleague spoke to her in Spanish, I knew my classes would be useless for her and I realized how much better off was than this poor woman.

    I decided to do something for her. I wrote to a newspaper expressing how I felt about the unselfishness of the Cookie Lady who needed a job. A few days later, my article appeared in the newspaper and the Cookie Lady was allowed to stay in her position. On the same day, I received a letter, which seemed so unlikely that I read it twice. “An editor of a local magazine likes your piece and wants you to call her next time you're looking for work …”

    Imagine possessing something that you loved so much. Imagine what it would feel like if you lost it. While that item may be something as simple as a doll, you would still feel very upset, but you could replace it with a new one. Now imagine losing something that you depend on for survival and cannot be replaced. That is what it would be like if we lost the natural environment around us.

    Firstly, I believe the environment should be preserved because it supports human life. One of the largest examples is that we get all of our food and drinks from the environment. If the environment were to be destroyed beyond revival, then the human race would be over in months. Scientists have yet to find another planet with similar conditions to the Earth, and if it's found, we don't have the technology to get to that planet on time.

    Secondly, I believe that the environment serves as an amazing educational tool for students. When I was in second grade, I had an absolute interest in animals. When we had a field trip to the Daggerwing Nature Center, I was very excited. When we got there, I could hardly believe what I was seeing. There was a bridge to get to the main building, and under the bridge was a small swamp (沼泽) with turtles, fish, and my personal favorite, alligators. I was so surprised that I almost ran into the tour guide. We walked into the building and saw various animals in their habitats. I was so inspired by this visit. Six years later, I have taken an animal behavior class for three weeks. Meeting by chance with the environment can inspire people, and if preserved it will continue to inspire people.

    In conclusion, the environment is so valuable because it can't be replaced, keeps us alive, and serves as a great educational tool.

    Many leading AI researchers think that in a matter of decades, artificial intelligence will be able to do not merely some of our jobs, but all of our jobs, forever transforming life on Earth.

    The reason why many regard this as science fiction is that we've traditionally thought of intelligence as something mysterious that can only exist in biological organisms, especially humans. But such an idea is unscientific.

    From my point of view as a physicist and AI researcher, intelligence is simply a certain kind of information-processing performed by elementary particles (基本粒子) moving around, and there is no law of physics that says one can't build machines more intelligent than us in all ways. This suggests that we've only seen the tip of the intelligence iceberg and that there is an amazing potential to unlock the full intelligence that is potential in nature and use it to help humanity.

    If we get it right, the upside is huge. Since everything we love about civilization is the product of intelligence, amplifying (扩大) our own intelligence with AI has the potential to solve tomorrow's toughest problems. For example, why risk our loved ones dying in traffic accidents that self-driving cars could prevent or dying of cancers that AI might help us find cures for? Why not increase productivity through automation (自动化) and use AI to accelerate our research and development of affordable sustainable (可持续的) energy?

    I'm optimistic that we can develop rapidly with advanced AI as long as we win the race between the growing power of our technology and the knowledge with which we manage it. But this requires giving up our outdated concept of learning form mistakes. That helped us win the race with less powerful technology: We messed up with fire and then invented fire extinguishers (灭火器), and we messed up with cars and then invented seat belts. However, it's an awful idea for more powerful technologies, such as nuclear weapons or superintelligent AI—where even a single mistake is unacceptable and we need to get things right the first time.
