Many blind people use guide dogs to help them get safely from place to place and to warn them of danger. But what can blind people do if they are allergic(过敏的) to dogs or just don't like them? For these people, they can turn to the Guide Horse Foundation.

    Janet and Don Burleson founded(成立) the organization in 1999. They began training miniature horses to help guide blind people. Miniature horses look just like common horses, only much smaller. They are generally less than 34 inches tall.

    Cuddles was the foundation's first guide horse in full service. She became 45-year-old Dan Shaw's helper. Shaw has an eye disease and his sight is very poor. One night, while filling out a form to get a guide dog, Shaw heard a news story on TV about people training horses to guide the blind. Shaw loves horses and wanted a guide animal that would live a long time. So he applied(申请)，and a year later, Cuddles and Shaw began training as a team.

    On a trip to New York, Cuddles helped Shaw safely visit many places of interest .They even traveled on a boat and on the subway system.

    Shaw says that he is very lucky to have Cuddles. He believes that Cuddles has changed his life for the better by giving him the chance to do things himself and making him feel much more confident about himself.

    You eat food and drink water, right? Skipping Rocks Lab is changing how you and your future generations will have water. Have you ever thought you could eat water? Think again, this is actually happening somewhere in the world.

    The group at Skipping Rocks Lab has made a water bottle you can eat. The product is called Ooho. Unlike plastic bottles, Oohos are neither tall nor hard. They look more like bubbles, or small, round, clear balls. They can hold liquid inside. People who drink Oohos can be surprised: the outside bursts in the mouth.

    Rodrigo Garcia Gonzalez is with Skipping Rocks Lab. He explains that the outside, or the membrane, of Ooho is made of seaweed, a plant that grows in the ocean. “It's a membrane made of seaweed that can contain water or any kind of liquid. It's made from an extract (汁) of the brown seaweed.”

    The Ooho membrane is tasteless, and you can eat it. The company says even if you throw away the membrane, it will break down in about four weeks. Gonzalez says the membrane is strong, and good for the environment.

Every year, billions of plastic water bottles are thrown away, polluting land and waterways around the world. The typical water bottle made of plastic can take hundreds of years to degrade.

    Lise Honsinger is also with Skipping Rocks Lab. “Most people just grab a bottle of water, hold it for five minutes, drink it, and throw it away. How can that then exist for 700 years? So, yeah, this is absolutely a solution to that. We are very purist: we don't want to see this packaged in plastic.”

    There are limits to the Ooho. It cannot be refilled. Each bottle is small. And Oohos do not store for more than a few days. The Skipping Rocks Lab is working on those issues. “We're still working on things like extending the shelf life, looking at different options in terms of thickness, if we want to make one that stands up more, or more flexible for marathons where people just want to eat it whole.”

    Right now, Skipping Rocks Lab can make only a few thousand Oohos a day. But it is developing new technology that could increase that number to hundreds of thousands.

    With the start of the new term, the students around the country exchange their fun and fashionable clothes for boring school uniforms. But not all schools are fashion deserts. Colorful sports shoes, school bags, T-shirts and even drink containers are breathing life into campuses.

    "The uniform makes us look like a bunch of clones, especially when we are doing morning exercises on the playground," said Qing Pei, a Senior 2 from Shanghai Qibao High School. "But the boys wear different sports shoes and girls have different decorations in their hair. These are the areas where you can express yourself," said Qing.

    Although it might be strange for boys to talk about fashion, they do care about what they wear in school, especially shoes, according to Qing.

    "Nike and Adidas basketball shoes, although they are still the must-have items for many of my friends, are becoming out-of-date," Qing added. He explained that "Since Liu Xiang ran so fast in Athens, running shoes are becoming popular in this autumn. "

    "Still in fashion are the various baseball caps and American-style T-shirts with random (随意的) English words printed on them," said Qing. "The accuracy of the written message is not important. Often, the words are not spelt correctly. Sometimes they do not even make sense, "Qing said with a smile.

    Besides sports shoes and T-shirts, styles and colors of school bags are another opportunity for students to express their taste in fashion. Some bags are made more eye-catching by decorating them with small hanging dolls.

    Other fashionable items are the colorful drink containers which are now popular among girls this term.

    "Some teachers are surprised to see a teenager sucking a bottle like this at school and criticize it as a childish regression (退化). But some girls just love it," said Yang Rui, a Senior 3. from High School attached to Xi'an Jiaotong University.

    The United States Congress is responsible for making and approving federal laws—rules that everyone in the country must follow. But exactly how do those laws get made? The process is not easy, and it takes a long time.

    A law begins when someone puts forward an idea. The idea can come from anyone, but it has to get to a U. S. lawmaker who wants it to become legislation. In time, the idea is further developed into a written proposal, called a bill.

    Then, a member of Congress officially proposes the bill. After the bill is introduced, it is sent to a small group of lawmakers, called a "committee". Sometimes committee members seek more information about the proposal by holding hearings. Sometimes the committee changes the bill. Sometimes it decides not to take any action. In that case, we say lawmakers "table" the bill, or let it "die in committee".

    But now and then, the bill is offered to lawmakers not on the committee. Those lawmakers debate the bill further. They might change the bill again. Finally, the full House or Senate votes on the bill. If it does not earn the majority of votes, the bill does not advance.

    Finally, the agreed-upon bill is sent to the president. If the president signs it, the bill becomes a law. If the president does nothing and Congress is officially meeting, the bill becomes a law. But if the president does nothing and Congress is not in session, the bill does not pass. Or the president can officially reject the bill. If that happens, the bill is not stopped. Instead, it is returned to both the Senate and the House. If two-thirds of the senators and two-thirds of the House members approve the bill once again, even with the president objecting, they turn the bill into a law.

How do you kill your time when you go to work? Most of us stare at our cell phones, and refuse to make eye contact with others. We just read, chat with others online or play games online. Or maybe we're using the time between stops to do our make-up, catch up on emails, or read a few chapters of a book. However, Dina Alfasi takes a very different approach.

Each day she has to travel hours on buses and trains to get to her engineering job at a hospital in Israel. Rather than look at her cell phone in silence, she uses one very special way to have connection with strangers. It is portraits of the people she meets on public transport every day that she is taking. The photographs catch those quiet and personal moments of people readying themselves for the day ahead. Some people lean their heads against the window and go to sleep, some stare into space and have a daydream, and others sit quietly to read their documents or books. Each picture captures one tiny moment in people's lives, ripe with potential for your imagination. It is wonderful for her to look at someone's commute(上下班) and make up an entire story about the rest of their daily existence, from the father travelling with a baby to the woman welcoming a change.

"What inspires me very much are the little moments that happen every day," Dina told My Modern Met. "My work is to tell stories through a single portrait, and it proves that all you need is just to look around and find those magic moments."

With a brain the size of a pinhead, insects perform fantastic navigational （导航的）abilities. They avoid obstacles and move through small openings. How do they do this, with their limited brain power? Understanding the inner workings of an insect's brain can help us in our search towards energy-efficient computing, physicist Elisabetta Chicca of the University of Groningen demonstrates with her most recent result: A robot that acts like an insect.

In search of the neural（神经的） mechanism that drives insect behaviour, PhD student Thorben Schoepe developed a model of its neuronal activity and a small robot that uses this model to navigate. Schoepe's model is based on one main principle: always steer towards the area with the least apparent motion.

He had his robot drive through a long "corridor"—consisting of two walls with a random print on it—and the robot centred in the middle of the corridor, as insects tend to do. In other virtual environments, such as a space with obstacles or small openings, Schoepe's model also showed similar behaviour to insects.

"The model is so good," Chicca concludes, "that once you set it up, it will perform in all kinds of environments. That's the beauty of this result."

The fact that a robot can navigate in a realistic environment is not new. Rather, the model gives insight into how insects do the job, and how they manage to do things so efficiently.

Chicca explains, "Much of robotics is not concerned with efficiency. We humans tend to learn new tasks as we grow up and within robotics. This is reflected in the current trend of machine learning. But insects are able to fly immediately from birth. An efficient way of doing that is hardwired in their brains. In a similar way, you could make computers more efficient."
