    Whether in the home or the workplace, social robots are going to become a lot more common in the next few years. Social robots are about to bring technology to the everyday world in a more humanized way, said Cynthia Breazeal, chief scientist at the robot company Jibo.

    While household robots today do the normal housework, social robots will be much more like companions than mere tools. For example, these robots will be able to distinguish when someone is happy or sad. This allows them to respond more appropriately to the user.

    The Jibo robot, arranged to ship later this year, is designed to be a personalized assistant. You can talk to the robot, ask it questions, and make requests for it to perform different tasks. The robot doesn't just deliver general answers to questions; it responds based on what it learns about each individual in the household. It can do things such as reminding an elderly family member to take medicine or taking family photos.

    Social robots are not just finding their way into the home. They have potential applications in everything from education to health care and are already finding their way into some of these spaces.

    Fellow Robots is one company bringing social robots to the market. The company's "Oshbot" robot is built to assist customers in a store, which can help the customers find items and help guide them to the product's location in the store. It can also speak different languages and make recommendations for different items based on what the customer is shopping for.

    The more interaction the robot has with humans, the more it learns. But Oshbot, like other social robots, is not intended to replace workers, but to work alongside other employees. "We have technologies to train social robots to do things not for us, but with us," said Breazeal.

    Most Europeans want small cars. Many Americans prefer large cars. As a result, European automakers produce a large number of economical, light weight cars, while American automakers build bigger, heavier cars.

    The price of gas has much to do with this. The petrol is expensive in Europe, so Europeans naturally prefer cars that will go a long way on a small amount of fuel. There are other reasons. Many European cities have very narrow streets. In these cities a small car is more practical and easier to handle than a large one.

    Some Americans like powerful engines in their cars. They enjoy having wider cars that are comfortable for large families and long trips. They are prepared to pay higher costs to get these advantages. Other Americans, however, have learned to like the small and smart cars. Many visitors to Europe during and after World War I discovered that small cars were fun to drive and easy to park in small spaces. They were delighted to learn how far small cars could go on a few gallons of gasoline.

    In the 1950s many Americans began buying European cars. In 1957, for the first time, the United States imported more cars than it exported. The best seller among these imported cars was a cool-looking but small car from Germany. Americans immediately gave it another name “ the bug”.

    Today, American car buyers have a wider choice. There are big cars for people who want large room, comfort, and power. And there are small cars, mostly imported but some American-made, for people who want easy parking and economical operation.

    Why is it that many people who have suffered a major shock, such as divorce or death of a family member, seem to be weaker against a variety of major and minor illness? One common idea among psychologists has been that people could deal with suffering more effectively if they were able to understand and accept it. Indeed, many experts stress the value of expressing thoughts and feelings connected with upsetting events.

    Recently, a team of medical researchers studied the links between describing psychologically painful events and long-term health. In one experiment healthy college students were asked to write about either personally disturbing experiences or ordinary topics over a period of four days. In the months afterwards, students who had chosen to show their inner thoughts and feelings in their writing visited the health center for illness much less often than those who had written about everyday topics.

    In an experiment that followed, another group of healthy students were given the four-day writing exercises. Some chose to write about highly personal and upsetting experiences (including loneliness, problems with family and friends, and health). When questioned immediately afterwards, they said that they did not feel any better. However, their blood samples(样本) taken before and after the experiment showed evidence of an improved resistance to illness. The white cells that fight off bacteria and viruses had increased their reaction and sensitivity to these "invaders". This trend continued over the following six weeks, when another blood sample was taken. Individuals who showed the best results were those who wrote about topics that they had actively kept from telling others about.

    The researchers suggested that failure to face up to painful experience can be a form of stress itself, and can increase the possibility of illness. It follows, then, that actively dealing with a major shock makes possible its understanding and acceptance. The answer is not to suffer in silence. It may not always be possible to talk about personal problems, but writing them down will help the body to fight disease in the long run.

    A Christmas Carol was written by Charles Dickens. The first 6,000 copies of the book were sold out in a week. And the book has inspired many plays and movies. The first play was put on in 1844. The first two movies were silent films made in 1901 and 1908. Since then, the story has been remade more than 60 times for television and cinema. What makes such a tale so attractive? Audiences have always loved a good plot, a villain(反面人物)who harms other people or breaks the law, and the ending of right over wrong. The book offers all three.

    The book tells the story of a man named Ebenezer Scrooge. He is mean and cruel(残忍的)to his clerk and turns away his only living relative. One night, Scrooge is visited by three spirits. The first shows scenes from Scrooge's youth that led to this present state. The second takes him to the homes of his clerk and his nephew. Here Scrooge sees that people can be happy without lots of money. The spirit also shows him the desperate poor people of London. The third spirit shows Scrooge will die alone, and no one will care if he continues to live as he has. At last the message is understood, and Scrooge repents. He becomes generous and caring to all around him, especially to his clerk's sick son, Tiny Tim.

    Every year, thousands of people watch A Christmas Carol. Why? They may be touched by its lessons on the true meanings of wealth and happiness. They may enjoy the special effects and feelings or watching every year may be just a habit. Viewers never seem to grow tired of the old miser(守财奴), Scrooge, and his dramatic message of hope and change.

As part of our mission to inspire the next generation of scientists, inventors and engineers, the Science Museum Group (SMG) has launched an exciting new online game—Total Darkness.

Over the last year we have been developing Total Darkness with the aim of creating an experience that can have a positive impact on people's attitudes towards STEM (science, technology, engineering and maths), as well as having a focus on self-reflection, rather than asking players to recall specific facts or concepts.

Total Darkness is a digital storytelling experience which encourages young people to recognise how the skills they use every day relate to STEM and can help them develop their confidence in science thinking. The game invites the player to solve a mysterious power cut in their hometown. The game puts players in control, allowing their choices and decisions to guide them through the story.

As the player navigates through the darkened streets of the town, equipped only with a torch, they will face various challenges. Using their curiosity, communication skills and creative problem solving, they will discover new theories about what might have caused the blackout(停电；断电). But with every step their torch fades, and the player must solve the mystery before the battery runs out.

The player's choices and actions throughout the game will score them curiosity, creativity or communication points. At the end, the skills the player has used will be revealed along with their science style, showing how they could put their skills into action in the real world.

Total Darkness is aimed at 8-15 year-olds—an important stage in teens' science development. Research shows that as teens make the step between primary and secondary, many move away from an interest in science as other influences have a stronger pull in their lives.

Total Darkness is a free online game playable on smartphone, tablet and desktop. Play now at totaldarkness.sciencemuseum.org.uk.
