The Future of Technology

    William, a businessman, arrives in a foreign airport. He doesn't show his passport. Instead, a machine in the wall reads the computer chip（芯片）in his arm. This contains information about him: his name, age, and I.D number. He exits the airport, and a car door opens when it “sees” him. The car takes him to his hotel. His room “knows” he has entered the building and it “reads” his body. He is cold, so the room becomes warmer. William then watches a business presentation on a video wall. When he takes a bath, the presentation “follows him and continues ”on the bathroom wall. Finally, the room plays music to help him sleep. It turns off the music when it “sees” him sleeping.

    William doesn't exist, and none of this is real. But it might be soon. “In five to ten years, computing and communications are going to be free and everywhere, in your walls, in your car, on your body,” says Victor Zue, leader of Project Oxygen.

    Project Oxygen has one big idea: to create better relationships between machines and people. The dream is that computer will learn to understand what people want.

    So, what changes will there be at work? Firstly, the building will know where everyone is, all the time. You want to talk to someone? Type the person's name on the nearest computer. It will show you a map of the building and exactly where this person is. You then call this person, who picks up the nearest telephone, also shown on the computer. If he or she is busy with a client（客户）or in a meeting, the computer will tell you.

    Is all this really possible? Visit the Siebel Center, Illinois and see for yourself: computers in the doors and walls, cameras everywhere, the technology of the future, but here today.

    When you go to St. Petersburg, the number of attractions can seem large. If you are short of time, or just want to make sure to hit the highlights, these are the top must-see sights in St, Petersburg.

The Hermitage Museum

    The Hermitage Museum is one of the most important sights to see for any visitor to St. Petersburg. There are lots of different paintings by the old masters in the Hermitage. Prepare to come face-to-face with classic Western artists.

Kizhi Island

    Kizhi Island is an open-air museum of wooden architecture from the Karelia Region of Russia. These impressive structures are made entirely without nails - the wood fits together with joints and grooves (沟槽）.

Peterhof

    Peterhof is as beautiful as it is fun. You'll be charged for admission, but go to Petethof when the fountains are working-during the day in the summer. They are shut off in winter evenings,

The Church of Our Savior on the Spilt Blood

    Love it or hale it, the Church of Our Savior on the Spilt Blood in St. Petersburg is an enthralling must-see sight. The beautiful look may make y our eyes brighten, and the painting inside the church will make you say “Wow!”

The Bronze Horseman Statue

    The so-called Bronze Horseman is a part of Russian culture and a symbol of St, Petersburg. Made famous by Alexander Pushkin, this statue of Peter the Great sitting on his horse can truly show Peter the Great's influence on the Russian idea of greatness.

    Empathy is the ability to share and understand the emotions of others. It is a construct of multiple components, each of which is associated with its own brain network. New research has found empathy may have a genetic component that affects personality, and cognition, psychiatric (relating to mental illness) conditions. The findings are highlighted in a new study led by researchers at the University of Cambridge, the University Paris Diderot and the Institute Pasteur, and 23andMe.

    Published yesterday in Molecular Psychiatry, the first study found evidence that genes influence our ability to read and understand emotions in others. The team at the Autism Research Centre at the University of Cambridge analyzed data from 89,000 individuals worldwide, the majority of whom were 23andMe customers, who were willing to be researched.

    Participants completed a “Reading the Mind in the Eyes Test”, in which they were shown photos of the area around the eyes and asked to identify one of two possible emotions. This assessed Theory of Mind and the ability to recognize and appreciate another person's mental state. Researchers identified that women with certain genetic variants（变异）on chromosome（染色体）3 performed better, with higher levels of empathy. Interestingly, male performance on the test was not associated with a genetic variant. Overall, women consistently performed better than men, exhibiting higher levels of empathy.

    The genetic variant associated with empathy in women is near the gene LRRN1(Leucine Rich Neuronal 1) on chromosome 3, which is highly active in an area of the human brain. Brain scans have indicated that this section of the brain may play a role in cognition empathy.

    This is also the unprecedented study that relates measures of empathy with variation in the human genome（基因组）. Previous research that has attempted to assess the genetic associations of personality and psychological traits has sometimes been unreliable, due to their small sample size. 23andMe's large data offering enables scientists to gain insight into the biology behind features such as empathy.

    23andMe is committed to furthering such research and approximately 85 percent of customers agrees to allow their de-identified（去识别的）data to be made available for study. By allowing scientists access to its unique and powerful research resource engine, 23andMe helps open up genetics to qualified researchers, providing novel insights into individuals' features, genetic diseases and a variety of other conditions.

    A recent experiment proves that bees can save time and energy when they fly around to different flowers.

    Dr Nigel Raine, from the Royal Holloway University of London, has always been interested in finding out why animal behave like they do. He is also interested in bees. It was not a surprise when he and some other scientists from Queen Mary University of London discovered that bees can quickly solve a problem that takes computers many days.

    Flowers make pollen (花粉), and when bees visit them, they carry the pollen to other flowers. The plants need the pollen to make seeds that will grow. Dr Raine notes that we get a lot of our food from plants, so it is important to know how the bees move around and take the pollen between flowers. The scientists wanted to examine the journey that the bees take and how they save energy when they do this. They completed the experiment on the roof of Queen Mary University, using artificial flowers and a large amount of nectar, a sweet liquid produced by flowers. They taught one bee to visit all the flowers in one place at the same time. When the bee got to know the location of the flowers well, they saw how it flew around and returned home with the nectar. After this, they changed the locations of the flowers. The scientists thought the bee would follow the route it knew already. This would mean that it followed a longer route than it needed to, and so it would use more energy. They watched the bee carefully as it travelled between the flowers in their new location, and they made notes. But in the experiment, the bee changed its route and flew a shorter distance.

    The problem that the bee solved is similar to a maths puzzle called the 'travelling salesman problem'. A salesman who goes to different places to sell things wants to travel the shortest distance. But he has to calculate the length of many possible routes to know which one is the shortest. A computer can calculate this but the experiment shows bees can do the same calculation quickly with a tiny brain. Scientists are very interested in how they do this. It would help us to understand how pollen is moved around. In addition, if they find this out, it could help us to improve communication networks. This might help humans to reduce traffic jams when there is an accident, for example.

    Scientists are studying different foods, and they will see which foods protect us from cancer (癌症), and which cause it. It is known that a healthy diet (饮食) will help keep a healthy body weight, which can also decrease the risk (风险) of many types of cancer.

    Fruit and vegetables

    Fruit and vegetables are an important part of a healthy diet. They can decrease the risk of some cancer types like mouth and throat cancer. They are a good source of many important nutrients such as vitamin A, vitamin C, vitamin E, and are an excellent source of fiber.

    Our advice

    Try to get plenty of fruit and vegetables in your diet. Eating fruit and vegetables with a variety of colors will help you get many kinds of vitamins and minerals as the chemicals that give these foods their colors are good for you.

    Meat

    Eating lots of red and processed meat can increase (增加) your risk of stomach cancer. Red meat includes all fresh and frozen beef, pork and lamb. Processed meat includes ham, bacon and sausage. White meat, such as chicken, is unlikely to increase your risk of cancer.

    Our advice

    Eat smaller and fewer parts of red and processed meat. Try using beans or peas instead of meat in your diet. When you cook meat, use low-temperature methods.

    Fat

    Fat is a necessary part of our diet but high-fat diet can increase our risk of cancer, heart disease and other diseases. Meat is higher in saturated fat (饱和脂肪) and eating too much saturated fat may increase your risk of breast cancer.

    Our advice

    Try not to eat too much fatty foods. In particular, try to cut down on saturated fat contained in fatty meat, biscuits, and butter. Try to avoid frying foods in lots of oil.

    Your teenage best friend could be good for your long-term mental health, according to a new study published in the journal Child Development According to the findings, teenagers aged 15 to 16 who had a close friendship rather than a larger group of friends they were less close to had a greater sense of self-worth by the time they were 25 years old. Those people with a very close best friend were also less likely to experience depression and social anxiety, the study found.

    "Close friendship strength in mid-adolescence predicted relative increases in self-worth and decreases in anxiety and depressive symptoms by early adulthood, "the authors, led by Rachel K, Narr, a postdoctoral student focused on clinical psychology at the University of Virginia, wrote.

    A past research has suggested that adolescent friendships are important. Friendships during the teenage years predict academic success and improved mental health. But the new research further explores the type of friendships teenagers have. "My hunch(预感)was that close friendships compared to broader friendship groups and popularity may not function the same way," Narr told Quartz. "Being successful in one is not the same as being successful in the other."

    Many study participants did not continue to have a close relationship with their high-school best friend, leading the researchers to wonder what exactly was responsible for the mental health benefits. They suspected that the skills and ability to build such a friendship may be more important than the friendship itself.

    And as the researchers point out, those skills are not necessarily brought to bear in the world of social media. "As technology makes it increasingly easy to build a social network of shallow friends, focusing time and attention on developing close connections with a few individuals should be a priority," study co-author Joseph Allen said in a statement.
