The human brain contains 10 thousand million cells and each of these may have a thousand connections. Such enormous numbers used to discourage us and cause us to dismiss the possibility of making a machine with human-like ability, but now that we have grown used to moving forward at such a pace we can be less sure. Quite soon, in only 10 or 20 years perhaps, we will be able to assemble a machine as complex as the human brain, and if we can we will. It may then take us a long time to render it intelligent by loading in the right software (软件)or by altering the architecture but that too will happen.

    I think it certain that in decades, not centuries, machines of silicon (硅) will arise first to compete and then do better than their human ancestors. Once they do better than us they will be capable of their own design. In a real sense they will be able to reproduce themselves. Silicon will have ended carbon's long control. And we will no longer be able to claim ourselves to be the finest intelligence in the known universe.

    As the intelligence of robots increases to match that of humans and as their cost declines through economies of scale we may use them to improve environments. Thus, deserts may bloom and the ocean beds be mined. Further ahead, by a combination of the great wealth this new age will bring and the technology it will provide, the construction of a vast, man-created world in space, home to thousands or millions of people, will be within our power.

    Taking a shower is relaxing. You can hum a song, daydream or think about nothing, leaving the real world behind you. But did you know that showering can also benefit your mind?

    A research by Scott Barry Kaufman, a psychologist from Yale University in the US interviewed over 3,000 people around the world. It turned out that nearly two-thirds of the interviewees said they had experienced new ideas in the shower and were more likely to have them in the shower than at work.

    So why does a simple shower have such magic power? Science can explain it.

    Showering can help to raise our level of dopamine, a hormone (荷尔蒙) closely related to our creativity. “People vary in terms of their level of creativity according to the activity of dopamine”, explained Alice Flaherty, a famous American neuroscientist. “Taking a warm shower can make us feel relaxed and therefore make the dopamine level rise and bring ‘Aha!' moment to us.”

    Besides the chemical changes, showering may give you a break from what you feel you have been stuck with. Especially when you have thought hard all day about a problem, jumping into the shower can keep you from the outside world so that you can focus on your inner feelings and memories. In this way, according to American psychologist Shelley H. Carson, author ofYour Creative Brain, “a showering hour may turn into an ‘incubation (孵化) period' for your ideas.”

    Compared with sitting in front of a computer, taking a shower is something we do less frequently in our daily life. When showering, we get a fresh experience with the change of location, temperature and humidity. “New and unexpected experiences can lead to positive changes in thinking,” explained Kaufman. “Getting off the couch and jumping in the shower may create a distance and force you to think from a new point of view.”

    Showering allows us to enjoy the creative juices of our minds, but it needn't just be the bathroom where you get your inspiration. For instance, Gertrude Stein, a female American writer and poet, got new ideas by driving around a farm and stopping at different cows until she found the one that most inspired her. So try to create your own way to free your mind, whether it's a walk near the ocean, a country drive or reading a book at home.

    Why do some people live to be older than others? You know the standard explanations: keeping a moderate diet, engaging in regular exercise, etc. But what effect does your personality have on your longevity(长寿)? Do some kinds of personalities lead to longer lives? A new study in the Journal of the American Geriatrics Society looked at this question by examining the personality characteristics of 246 children of people who had lived to be at least 100.

    The study shows that those living the longest are more outgoing, more active and less neurotic (神经质的) than other people. Long-living women are also more likely to be sympathetic and cooperative than women with a normal life span. These findings are in agreement with what you would expect from the evolutionary theory: those who like to make friends and help others can gather enough resources to make it through tough times.

    Interestingly, however, other characteristics that you might consider advantageous had no impact on whether study participants were likely to live longer. Those who were more self-disciplined, for instance, were no more likely to live to be very old. Also, being open to new ideas had no relationship to long life, which might explain all those bad-tempered old people who are fixed in their ways.

    Whether you can successfully change your personality as an adult is the subject of a longstanding psychological debate. But the new paper suggests that if you want long life, you should strive to be as outgoing as possible.

    Unfortunately, another recent study shows that your mother's personality may also help determine your longevity. That study looked at nearly 28,000 Norwegian mothers and found that those moms who were more anxious, depressed and angry were more likely to feed their kids unhealthy diets. Patterns of childhood eating can be hard to break when we're adults, which may mean that kids of depressed moms end up dying younger.

    Personality isn't destiny, and everyone knows that individuals can learn to change. But both studies show that long life isn't just a matter of your physical health but of your mental health.

    When my father married my mother in 1943 he gave my mother a 1937 crown coin and told her to keep it in the back of her purse and not spend it. This would mean that she always felt that she was protected and would always have money if she really needed it.

    When I was married in 1970 my husband who had heard this story obtained a 1937 crown for me and I have always kept it in my wallet and I have always had enough for my needs.

    A friend recently fell on hard times partly through external (外部的) circumstances and partly through poor planning. Friends and I have loaned her money, paid her bills, even given her food and tried to teach her budget techniques, but none of them has been a solution. She has just slipped deeper and deeper into financial trouble and depression.

    Last week she looked pale and unwell, very depressed and hopeless. I then thought about how the crown, a reminder of another's care and love, had protected me so I went to the bank for a $100 dollar bill. I told my friend the story and asked her to keep the $100 in the back of her wallet. It turned out that she didn't have a wallet so she put the money in a little pencil case where she kept her coins. She immediately felt better. "I feel rich and thank you for being a good friend" she said and we were both a bit teary.

    The reason for passing this on is not to praise any generosity on my part but to show the power of "random acts of kindness". I went home and remembered a little wallet I had that I'd never used and thought "I'll give that to my friend." I opened it and inside found $100. The universe is very just and if your heart is open the reward always comes.

    Since 50 years ago, scientists have been searching for ways to link the brain with computers. Brain Computer Interface (BCI) technology could help people with disabilities send commands to machines.

    Recently, two researchers, Jose Millan and Michelle Tavella from the Federal Polytechnic School in Lausanne, Switzerland, demonstrated (展示) a small robotic wheelchair directed by a person's thoughts.

    In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts.

    "Our brain has billions of nerve cells. These send signals through the spinal cord (脊髓) to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles," Tavella says, "Our system allows disabled people to communicate with external world and also to control devices."

    The researchers designed a special cap for the user. This head cover picks up the signals from the scalp (头皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path. They help the computer react to commands from the brain.

    Prof. Millan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands. "The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices. One example is this wheelchair." He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can benefit from. And the other is to guarantee that they can use the technology over long periods of time.

    China's popular "Singles' Day", better known as "Double Eleven", started out as a day to celebrate singles symbolized by the four number ones on the date of November 11.

    With time that meaning has changed. In 2009, China's e-commerce leader Alibaba set the day as a lucky shopping day for online sales as the date was both easy to remember and perfectly timed as it hit between the consumer spending lull (间歇) between National Day and Chinese New Year. It soon became a hit, and Double Eleven became a buying frenzy (疯狂) spread across the world's second largest economy.

    In 2019, the Double Eleven Shopping Festival entered its eleventh year. During this decade, Alibaba, Chinese e-commerce giant, and other e-commerce platforms, together with consumers, have co-created a very big shopping event whose heat has swept the world. Foreign readers share their ideas on Singles' Day in China:

    GhostBuster (UK) I think Double Eleven is unbelievable. It is not a religious festival that people of the same religion but living in different countries share. As an e-commerce faithful fan, I really love the shopping festival.

    Emanreus (Australia) I work in Shanghai. Many of my young female colleagues are still single. They simply haven't time to date, as they tend to work long hours then travel two hours by subway to get to and from work. Single's Day is a day when they give themselves a treat with online shopping.

    BlondeAmber (Ireland) There is not hing to be proud of to be in a country that spends so much online on a particular day. It does nothing more than show the superficiality (肤浅) of the temporary pleasure of shopping, and produces nothing more than a mountain of environmental waste. I bet there is plenty of buyers' deep regret after this day.

    Ionstar (US) Singles Day became a big deal for Valentine's Day not for the singles! Well, Alibaba's 11. 11 has become more famous and important than that of Black Friday and Cyber Monday!
