Can eating a chocolate bar every day really prevent age-related memory loss? No. But a new research shows that large amounts of flavones, substances found in cocoa, tea and some kinds of vegetables, may improve age-related memory failure.

    Dr. Scott Small is a professor of neurology (神经病学) at Columbia University in new York City. He is the lead writer of a research paper describing the effects of cocoa flavones on brain activity. His study involved 37 volunteers aged between 50 and 69. Researchers gave them a high-level flavones drink made from cocoa beans or a low-level flavones drink. For a period of three months, some subjects got 900 milligrams of flavones a day. The others got 10 milligrams of flavones each day. Brain imaging and memory tests were given to each study subject before and after the study. Dr. Small says that the subjects who had the high-level flavones drink showed much improvement on memory tests.

    The researchers warn that more work is needed to be done because this study was performed only on a small group. Dr. Joann Manson is the lead researcher of a four-year study involving 18,000 adults. This study will use flavones capsules(胶囊). The study subjects will be divided into two groups and will take two pills per day. The capsules used will all look the same. But one group's capsules will contain flavones, while the other group will take capsules made of an inactive substance, or placebo

    Dr. Manson says it's not necessary for people to start eating more chocolate, because a person would have to eat a huge amount of chocolate to get the same level of flavones given to the rest subjects. He adds many manufacturers have planned to remove the flavones from their chocolate products. Similarly, Dr. Manson says a cocoa-based flavones extract(提取)may be developed in the future But he says that more studies are needed to see how much flavones is good for our health.

    I still remember my first day at school in London and I was half-excited and half-frightened. On my way to school I wondered what sort of questions the other boys would ask me and practiced all the answers: “I am nine years old. I was born here but I haven't lived here since I was two. I was living in Farley. It's about thirty miles away. I came back to London two months ago.” I also wondered if it was the custom for boys to fight strangers like me, but I was tall for my age. I hoped they would decide not to risk it.

    No one took any notice of me before school. I stood in the center of the playground, expecting someone to say “hello”, but no one spoke to me. When a teacher called my name and told me where my classroom was, one or two boys looked at me but that was all.

    My teacher was called Mr. Jones. There were 42 boys in the class, so I didn't stand out there, either, until the first lesson of the afternoon. Mr. Jones was very fond of Charles Dickens and he had decided to read aloud to us from David Copperfield, but first he asked several boys if they knew Dickens' birthplace, but no one guessed right. A boy called Brian, the biggest in the class, said: “Timbuktu”, and Mr. Jones went red in the face. Then he asked me. I said: “Portsmouth”, and everyone stared at me because Mr. Jones said I was right. This didn't make me very popular, of course.

    “He thinks he's clever,” I heard Brian say.

    After that, we went out to the playground to play football. I was in Brian's team, and he obviously had Dickens in mind because he told me to go in goal. No one ever wanted to be the goalkeeper.

    “He's big enough and useless enough.” Brian said when someone asked him why he had chosen me.

    I suppose Mr. Jones, who served as the judge, remembered Dickens, too, because when the game was nearly over, Brian pushed one of the players on the other team, and he gave them a penalty (惩罚). As the boy kicked the ball to my right, I threw myself down instinctively (本能地) and saved it. All my team crowded round me. My bare knees were injured and bleeding. Brian took out a handkerchief and offered it to me.

    “Do you want to join my gang (帮派)?” he said. At the end of the day, I was no longer a stranger.

    A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech integrated systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.

    “It's extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components (元件),” said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go-ahead to start piecing together the components. “The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own,” he said.

    They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings has a number of interdependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything it's connected to,” said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.

    While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers' fields or on the battlefield. “Basically it should be able to take off, land and fly around,” he said.

    Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications. “You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead,” he said. “So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day to day basis.”

    How many girls in this world fall behind? The answer is hard—too many to count. This is why the phrase “Go Get It Girl” popped up in my head one day. This would be my project. Thus begins the journey of my Cold Award project, the largest and most important step of Girl Scouts (女童子军).

    “Go Get It Girl” is a girl's self-empowerment (自我授权) project centered on a website called gogetitgirl.org. It focuses on areas including education, health, and financial literacy. The education section includes information on applying to college and, maintaining good grades. The health section contains information on basic health and self-respect. Lastly, the financial literacy section has all the information a girl needs to manage her money properly.

    As part of my project, I was able to work one-on-one with girls in elementary, middle, and high school. I gave a speech at a local high school's College Night. I spoke to Hispanic girls and their parents about applying to college. In addition, I worked with an organization called Cool Girls, Inc. Cool Girls is an organization focused on the advancement of girls in all aspects of their development. I worked at the afterschool program, Cool Girls Club. The girls I worked with were primarily minorities, and Cool Girls truly helps them to rise above any current difficulties in their lives.

    To provide inspiration for the girls who visit gogetitgirl.org, I interviewed successful women in my community, including a doctor and business owner.

The project has been a lot of work, arid it's not over yet. It will never be over, hopefully, because I will always look for ways to help girls.

    When we see a person in trouble, the first idea that comes to our mind is to lend a hand. But what if we see an animal in trouble, does the same rule apply?

    This question was raised after a group of penguins were saved from an icy gully（峡谷）in Antarctica. It was filmed for the BBC wildlife series Dynasties. The film crew were anxious when they saw that a group of penguins had fallen into a gully and been trapped with their young. They built a slope（斜坡）so that a few of the penguins could save themselves.

    The case has taken the international media by storm. Viewers watching this film let out a sigh of relief. "I'm so glad. I understand not taking action directly, but a helping hand isn't bothering, right?" viewer Kathryn Shaw said on her Facebook.

    However, others think human interference（干涉） is unnatural. "You can't have sunshine throughout your life. To have done anything else would only make matters worse," said the show's creator David Attenborough, according to The Times.

    In this case, however, Mike Gunton, the executive producer of the series, said that this was a one­off situation. "There were no animals going to suffer by interfering. You weren't touching the animals and it was just felt by doing this... they had the chance not to have to keep slipping down the slope," he told the BBC.

    Such cases are familiar to Paul Nicklen, wildlife photographer for National Geographic. He told Metro, "If it's ever a predator（捕食者）situation, no matter how gut­wrenching, you stay out of the way. Even when you're watching a male polar bear eat a baby bear."

    "There's no rule book in those situations. You can only respond to the facts that are right there in front of you," Will Lawson, the show's director, told Daily Mail.
