Picture the scene: You come home after work feeling too exhausted to cook –only to find a delicious meal worthy of a Michelin-starred restaurant waiting for you. It sounds like a fantasy, but it could be about to come true thanks to a robot chef developed by British scientists.

    Those scientists have come up with a set of robotic arms so smart that they are capable of cooking meals all by themselves. The device will be sold from as early as 2017 as part of a purpose-built high-tech kitchen.

    Scientists at Moley Robotics spent almost 18 years developing the hands. According to its creators, the arms can chop, stir, whisk and baste well enough to recreate almost anything you would care to eat, whether it is a simple home-cooked supper, or a complicated creation designed by a world-class chef. The hands move a little slowly, hovering strangely above the work surface whenever they are not busy, but they imitate human movements closely enough that they can do things such as wiping a spoon on the edge of a pan to prevent drips.

    Mr Oleynik, who is leading the project, said, “All the things which are possible with the hand are possible here. There is no limitation. A lot of people want to go to Michelin-starred restaurants, but they are quite expensive and may be quite far from the home. This is an opportunity for people to enjoy very good food, and for a reasonable price. ”

    The only cuisine that is off the robot's menu at the moment is sushi, which requires extremely steady pressure and nimble（敏捷的；敏感的） fingers to make, but the team plan to conquer that as well by the time it goes on sale.

    Writers used to approach publishers to have their work read by the public. Now they can simply post them and find millions of instant audience.

    After breaking up with her boyfriend, Bao Jingjing started “making up” a love story simply to distract her attention. Her story of a girl suffering the pain like hers progressed quickly, attracting many readers.

    When Bao stopped writing as she reunited with her boyfriend, she was urged to continue, as readers wanted to know what happened next. Bao finished it soon. It became so popular that it was turned into a best-seller. To cap it all off, Bao's novel was later adapted into a successful movie.

    Bao's story is only one of many Internet novels that have landed deals for physical books, TV shows and films. Unlike traditional writers who buried themselves in their books for years, some young writers like Bao have got readers rapidly online and found overnight success.

    Bao admits her success was unexpected. She still remembers how surprised her parents were when she proudly gave them her copyright earnings. Online literature forums(论坛) are platforms for grassroots writers to succeed.

    In recent years, Zhang Wei, known as “Tangjiasanshao”, has earned 177 million yuan by his fingers though working as an author was beyond his dreams. He topped the list of wealthiest Chinese Internet novelists twice and was the only online writer to be listed on the 2014 Forbes “Chinese Celebrity List”.

    He admits that he is one of the few writers at the top of the pyramid while most online writers remain unknown. However, he urged that his success can be achieved by others, as long as “they write hard enough”.

    Are you addicted to computer games? Do you stay up all night playing them? Do you feel happy after you play computer games? There's no doubt that the excitement and appealing of games these days makes them hard to put down. More and more people are attracted by the choice when it comes to gaming: You can role play--creating your own fantasy characters and stories, giving you a chance to step out of everyday life into an imaginary world. And there are shooting games where you can let out your anger and depression in violent situations where you kill people with guns. You can get excited from the games.

    However, can these kinds of games really be fun and can being absorbed in virtual reality be good for us? Should we worry about their effects on our health? Popular games like Grand Theft Auto have been blamed for everything from falling results at school to causing acts of extreme violence. Internet safety advisor, Alan MacKenzie, thinks “many people understandably will just think that a game is just a game and not realizing the exact content that's in there”. He gives an example of the violence, which he says is “wholly inappropriate for anybody, not to mention children.”

    Others will argue that gaming is a harmless form of entertainment. There is evidence that playing video games could actually be good for us. Some games are educational and using games certainly can help children learn good qualities. Studies have also shown that the skills used in playing games can cause growth in certain areas of the brain, the ability to think in 3D and even improve our eyesight.

    Video gamers are also no longer just simple creatures. Just as Edward Smith, the professor in Oxford University, puts it that for some, gaming is having a positive effect on their social lives with games like Halo and World of Warcraft often being played in groups. When your group works together to win the game, your sense of achievement is higher than when winning by yourself.

So every coin has two sides. It seems today, gaming isn't just for game fans and if used in a proper way, we can all take part. If video games have two sides, what side do you stand by?

    We have a strange obsession with the concept of perfection. “If I have the perfect parents and perfect grades, then I would be happy.” Under cultural influence, we seek what we can't have without remembering that we don't actually need to be perfect. Imperfection allows us to be human.

    Parents, teachers and other high-achieving peers will have us believe that we must be perfect if we wish to remain competitive. However, what job or school requires you to have a 2400 SAT, 4.0 GPA and develop a cure for some form of cancer by the age of 18? Although these would be great achievements, are they worth the cost of sleep? We feel like we need the perfect grades to get into the perfect college that will provide us with the perfect education necessary to obtain the perfect job. With this misconception, when writing our resumes(简历), we then seek out experiences that we think may help build a good name for ourselves. Feeding on our thirst for perfection, some college and career industries have been set up claiming to help us reach our goals.

    The truth is, you only need to be good enough. Don't worry about anything secondary to your passions. You won't become an expert at anything if you spend your time trying to succeed in everything you do. You only become an expert when you devote your time to the one or two projects that truly bring you joy.

    As members of this society, we have a responsibility to be excellent in what we do, not perfect. Although perfection can be a goal, it should not be the only goal. We only have 24 hours in a day. Thus, we need to prioritize(优先选择)what we want to do and cut out the activities we cannot do. If you enjoy debating, take a law class and see how it suits you. If you enjoy cooking, experiment in the kitchen and see what you can make!

    Try as hard as you can and let your future worry about itself. Worry about your task at hand and you will be successful in achieving your dreams. Above all, remember that you are going to be okay.

    More than two thirds of the world's polar bears will be wiped out by 2050, according to a shocking new study. By then, scientists say, global warming will have melted 42 percent of the Arctic sea ice. By 2100, only a very few of these important creatures will be left.

    The report has been produced by the US Geological Survey. The scientists have publicized their findings in the hope of influencing US Interior Secretary Dirk Kempthorne, who has been asked to put polar bears on the US endangered species list.

    Polar bears depend on floating sea ice as a platform for hunting seals, which are their main food. Without enough ice, polar bears would be forced to go onto the land, where they are poorly skilled hunters, and would be unlikely to adapt to the life on the land in time. Experts say few little bears would survive and the stress could make many females unable to get pregnant.

    The team of American and Canadian scientists spent six months studying bears, on the ground, from spotter planes and in the lab, using computer models. Some team members fear the result is even worse for the bears than what their report says. They say the Arctic is warming faster than anywhere in the world and much faster than their computer had been forecasting. Satellite observations have showed that the ice has decreased to an all­time low.

    However, not everyone in the scientific community believes that global warming is happening on such an alarming scale. Another investigation has found that polar bears are still being hunted by wealthy “sportsmen” who want their skins and heads. At least ten international companies offer bear­hunting trips.

    Donna Strickland is a professor in the Department of Physics and Astronomy. Professor Strickland is one of the recipients(受领者) of the Nobel Prize in Physics 2018 with Gérard Mourou, her PhD supervisor at the time. They published this Nobel-winning research in 1985 when Strickland was a PhD student at the University of Rochester in New York state. Together they paved the way toward the most intense laser pulses ever created.

    Professor Donna Strickland is only the third woman ever to have won a Nobel Prize in physics. She and her fellow winners were honored for what the Nobel Committee called ground-breaking inventions in laser physics. Professor Strickland devised a way to use lasers as very precise drilling or cutting tools. Millions of eye operations are performed every year with these sharpest of laser beams.

    "How surprising do you think it is that you're the third woman to win this prize?"

"Well, that is surprising, isn't it? I think that's the story of Maria that people want to talk about — that why should it take 60 years? There are so many women out there doing fantastic research, so why does it take so long to get recognized?"

    Physics still has one of the largest gender gaps in science. One recent study concluded that at the current rates it would be more than two centuries until there were equal numbers of senior male and female researchers in the field.

    The last woman to win a physics Nobel was German-born Maria Goeppert-Mayer for her discoveries about the nuclei of atoms. Before that it was Marie Curie, who shared the 1903 prize with her husband, Pierre. This year's winners hope that breaking this half century hiatus will mean the focus in future will be on the research, rather than the gender of the researcher.
