If you could have one superpower, What would it be ?

    Dreaming about whether you would want to read minds , see through walls , or have superhuman strength may sound silly , but it actually gets to the heart of what really matters in your life 1

    Every day in our work , we are inspired by the people we meet doing extraordinary things to improve the world.

    They have a different kind of superpower that all of us possess : the power to make a difference in the lives of others .

    We're not saying that everyone needs to contribute their lives to the poor . Your lives are busy enough doing homework , playing sports , making friends , seeking after your dreams . But we do think that you can live a more powerful life when you devote some of your time and energy to something much larger than yourself . Find an issue you are interested in and learn more . Volunteer or , if you can , contribute a little money to a cause . Whatever you do , don't be a bystander . Get involved . You may have the opportunity to make your biggest difference when you're older . But why not start now ?

    Our own experience working together on health , development , and energy the last twenty years has been one of the most rewarding parts of our lives . It has changed who we are and continues to fuel our optimism about how much the lives of the poorest people will improve in the years ahead .

    Are you preparing for a big test? If so, you may want to go play some basketball in between hitting the books. Doctors are starting to find more and more information that suggests a connection between exercise and brain development. Judy Cameron, a scientist at Oregon Health and Science University, studies brain development. According to her research, it seems that exercise can make blood vessels, including those in the brain, stronger and more fully developed. Dr. Cameron claims this allows people who exercise to concentrate better. As she says, “While we already know that exercise is good for the heart, exercise can really cause physical changes in the brain.”

    The effects of exercise on brain development can even be seen in babies. Babies who do activities that require a lot of movement and physical activity show greater brain development than babies who are less physically active. With babies, even a little movement can show big results. Margaret Barnes, a pediatrician（儿科医生）, believes in the importance of exercise. She thinks that many learning disabilities that children have in elementary school or high school can be traced back to a lack of movement as babies. “Babies need movement that stimulates their five senses. They need to establish a connection between motion and memory. In this way, as they get older, children will begin to associate physical activity with higher learning,” says Margaret.

    Older people can strengthen their brains as well. Columbia University studied a group of seniors ranging in age from seventy to seventy-nine. Their study showed a short-term memory increase of up to 40 percent after exercising just three hours a week. The exercise does not have to be very difficult, but it does have to increase the heart rate. Also, just like the motion for babies, exercise for older people should involve some complexity. Learning some new skills or motions, such as with yoga or tai-chi, helps to open up memory paths in the brain that may not have been used for a long time.

    For most people, any type of physical activity that increases the heart rate is helpful. The main goal is to increase the brain's flow of blood. And your brain can benefit from as little as three to four hours of exercise a week.

    An open office is supposed to force employees to cooperate. To have them talk more face to face. To get them off instant messenger (IM) and brainstorming new ideas. But a recent study by two researchers offers evidence to support what many people who work in open offices already know: It doesn't really work that way. The noise causes people to put on headphones and tune out. The lack of privacy causes others to work from home when they can. And the sense of being in a fishbowl means many choose email over a desk-side chat.

    Ethan Bernstein and Stephen Turban, two Harvard Business School professors, studied two Fortune 500 companies that made the shift to an open office environment from one where workers had more privacy. Using “sociometric” electronic badges (徽章) and microphones, as well as data on email and instant messenger use by employees, the researchers found in the first study that after the organization made the move to open-plan offices, workers spent 73% less time in face-to-face interaction. Meanwhile, email use rose 67% and IM use went up 75%.

    The participants wore the badges and microphones for several weeks before the office was redesigned and for several after, and the company gave the researchers access to their electronic communications. The results were astonishing. “We were surprised by the degree to which we found the effect,” Bernstein said. The badges could tell that two people had a face-to-face interaction without recording actual spoken words. The researchers were careful to make sure other factors weren't in question—the business cycle was similar, for instance, and the group of employees were the same.

    In a second study, the researchers looked at the changes in interaction between specific pairs of colleagues, finding a similar drop in face-to-face communication and a smaller but still significant increase in electronic correspondence.

    Another wrinkle in their research, Bernstein said, is that not only did workers shift the way of communication they used, but they also tended to interact with different groups of people online than they did in person. Moving from one kind of communication to another may not be all bad—“maybe email is just more efficient,” he said—but if managers want certain teams of people to be interacting, that may be lost more than they think. The shift in office space could “have strong effects on productivity and the quality of work”.

    Bernstein hopes the research will offer evidence that will help managers consider the possible trade-offs of moving to an open office plan. In seeking a lower cost per square foot, they buy into the idea that it will also lead to more cooperation, even if it's not clear that's true. “I don't blame the architects,” he said. “But I do think we spend more of our time thinking about how to design workplaces based on the observer's angle”—the manager—“rather than the observed.”

    It is obvious that all of our childhood memories are not accidental. When you are a child, every scent, every sound, every move, every toy, the first day of school, the first kiss, the first step… Everything together makes what is the personality of a man. All these are pieces of one whole entity.

    I was about 6 years old. My mom's best friend left to another town and asked my mom to stay at her place with me for two days in order to look after her two sons. One was a little older than I was, and the second boy appeared to be super grown-up, for he was already fourteen. I always enjoyed staying at their place.

    I remember the second day we were supposed to have the come-back party for my mom's friend at her place. I woke up. Mom went to work and reminded me to be nice and clean by the time she came back. I stayed with Tony, the older of the boys and suddenly somebody called him and though he was not permitted to leave me alone-he left. He said it would not be long. But it took him forever. I realized that I was alone. I could not come out of the house, so I opened the window. I was so desperate. So lonely. So betrayed. At that moment I pulled the curtain so strongly that I fell on the floor. And there I was standing-one little criminal-desperate to escape and knowing that I would be punished for destroying the curtain that was not even ours.

But then something changed. I stopped weeping. I looked around and realized that I was in a safe place, and that mom would come back and kiss me no matter what I had done.

    This was a moment of pure happiness, not the happiness of getting a new toy or a dog, or going to the party of your best friend. It was the moment of clarity for me-the first time in my life when I realized that I was happy to have my mom and that I was safe. My eyes saw the world in different shades that moment. And by the way-I was not punished for the curtain. I fell asleep on my mom's knees.
