Paying a higher price than usual for a ticket to see a film in 3D is the annoyance of many a cinema-goer's life.

    But there may be a benefit to doing so, as a study has found that 3D films exercise the brain and improve short-term functioning in a similar way to brain-training tests.

    The research found that people who watched a movie in 3D improved cognitive (认知) skills, compared to those who watched it in 2D.

    The research was led by neuroscientist(神经学家) Dr Patrick Fagan from Goldsmiths University in London. More than 100 people took part in the experiment, where participants watched Disney film Big Hero 6 in either standard format or RealD 3D.

    They also carried out a brain-training-style test before and after seeing a section from the film. The test covered memory, reaction times and cognitive function and the results were compared later.

    According to the research, which was carried out in partnership with science group Thrill Laboratory, participants experienced a 23 percent increase in cognitive processing, as well as an 11 percent increase in reaction times.

    Dr Fagan said that the results showed enough of an improvement in brain function to suggest that 3D could play a part in improving brain power in the future.

    "These findings are more significant than you might think," he said. "It is a fact that people are living longer and there is a noticeable decline in cognitive brain function in old age which can worsen future quality of life. There has never been a better time to look at ways to improve brain function. The initial results of this study show that 3D films may potentially play a role in slowing this decline."

    A second part of the experiment involved those watching the film being fitted with headsets that scanned brain activity and this too showed heightened (加强的) activity when watching 3D. According to the results, participants were seven percent more engaged with what they were watching, adding to argument that 3D movies are more like watching real-life—something Professor Brendan Walker from Thrill Laboratory agreed with.

    "As Professor Brendan Walker's test concluded, 3D films are more attractive and heighten the senses — this, in turn, makes the brain run at quicker speeds," Dr Fagan said.

    I don't think there is anything more important than health. “Health is the greatest wealth，” wise people say. You can't be good at your studies or work well when you are ill.

    If you have a headache, toothache, backache, earache or bad pain in the stomach, if you complain of a bad cough, if you run a high temperature and have a bad cold, or if you suffer from high or low blood pressure, I think you should go to the doctor. The doctor will examine your throat, feel your pulse, test your blood pressure, take your temperature, sound your heart and lungs, test your eyes, check your teeth or have your chest X-rayed. After that, he will advise some treatment, or some medicine. The only thing you have to do is to follow his advice.

    Speaking about doctor's advice, I can't help telling you a funny story. An old gentleman came to see the doctor. The man was very ill. He told the doctor about his weakness, memory loss and serious problems with his heart and lungs. The doctor examined him and said there was no medicine for his disease. He told his patient to go to a quiet place for a month and have a good rest. He also advised him to eat a lot of meat, drink two glasses of red wine every day and take long walks. In other words, the doctor advised him to follow the rule: "Eat with pleasure, drink with pleasure and enjoy life as it is." The doctor also said that if the man wanted to be well again, he shouldn't smoke more than one cigarette a day. A month later the gentleman came into the doctor's office. He looked cheerful and happy. He thanked the doctor and said that he had never felt a healthier man." But you know, doctor," he said, “it's not easy to begin smoking at my age.”

    Academic learning is usually in the spotlight at school, but teaching elementary-age students “soft” skills like self-control and how to get along with others might help to keep at-risk kids out of criminal trouble in the future.

    Once a program called Fast Track was started in the early 1990s for more than 7,600 children of 55 schools in America. They were identified by their teachers and parents to be at high risk for developing aggressive behavioral problems. The students were randomly divided into two groups; half took part in the intervention, which included a teacher-led curriculum, parent training groups, academic tutoring and lessons in self-control and social skills. The program, which lasted from first grade through 10th grade, reduced delinquency(少年犯罪), arrests and use of health and mental health services as the students aged through adolescence and young adulthood.

    In another latest study, by looking at the data from nearly 900 students in previous findings, researchers found that about a third of the influence on future crime outcomes was due to the social and self-regulation skills the students learned from ages 6 to 11.

    The academic skills, or hard skills like learning of physics, which were taught as part of Fast Track, turned out to have less of an influence on crime and delinquency rates than did the soft skills, which are associated with emotional(情绪的) intelligence. Soft skills might include teaching kids to work cooperatively in a group or teaching them how to think about the long-term consequences when they make a decision.

    Researchers drew the conclusion that these soft skills should be emphasized even more in our education system and in our system of socializing children. Parents should do all they can to promote these skills with their children as should education policymakers. To the extent we can improve those skills, we can improve outcomes in delinquency.

    Captain America and Blackpanther were about to defend Earth from the criminal Thanos when Kevin Foley first noticed something was wrong. Foley, a 46-year old information-technology worker from Kyle, Texas, was heading into the theater to see Avengers: Infinity War when he realized he was having trouble breathing normally. The same symptom struck again during another movie the following night, but more severe this time. Once the cast on the second film rolled, Foley took action: he looked at his wristwatch. It was a bigger step than you might imagine, because Foley was wearing an Apple Watch equipped with medical sensors and experimental software to track basic functions of his heart. And the watch was worried. It had, according to the display, detected signs of an irregular heartbeat.

    Before long, Foley was in an emergency room, where doctors hooked him up to an ECG(心电图), which showed that he was in atrial fibrillation(心房颤动), an irregular heartbeat that can lead to blood clots(血栓), stroke and other potentially disastrous diseases. Foley spent the next few days in the hospital while doctors worked to return him to a normal heart rhythm eventually turning to a procedure called electrical cardioversion to shock his heart back to normal. Foley is doing fine now. But he believes that, if not for the warning on his watch, he might not have sought help in time. “I would have never known,” he says.

    Foley and his watch were part of an experiment run by Apple and Stanford's medical school. But beginning Dec. 6, anyone can get an on-the-fly heart checkup, assuming they've paid $399 or more for an Apple Watch. That's when Apple will launch a software update that turns its latest model, called the Series 4, into a personal ECG, thanks to an innovative new sensor. Though less complicated than hospital ECG machines, the watch version can still provide basic information and warnings of potential risks worthy of a closer look by a medical professional.

    For Apple, this new ECG-on-your-wrist is its biggest bet yet that personal technology will inevitably include personal health. Along with competitors, Apple has already offered fitness functions, such as apps to track the steps you've walked. But with the new ECG scan, Apple is moving straight into medical aspects of heath, a distinction underlined by the fact it sought and received Food and Drug Administration clearance for the clearance for the heart monitor.

    The conclusion of the Paris Agreement in 2015, in which almost every nation committed to reduce their carbon emissions(排放), was supposed to be a turning point in the fight against climate change. But many countries have already fallen behind their goals. Meanwhile emissions worldwide continue to rise.

    The only way to catch up is to aggressively pursue an approach that takes advantage of every possible strategy to reduce emissions. Wind and solar energy are usually part of this effort, but it must also include investing heavily in carbon capture(碳捕捉), utilization(应用)and storage(CCUS)—a range of technologies that pull carbon dioxide from the air, and transform it into useful materials or store it underground. Although CCUS has been opposed as too expensive and unproved, recent gains have made it far more effective. Improvements such as chemical compounds could drive the cost down from $1 00 per ton of captured carbon in 20 16 to $ 20 per ton by 2025, according to a 2016 article in Science.

    Three primary CCUS paths lead to the reduction of carbon emissions: retrofitting(改装)existing power plants; reducing emissions in industries that cannot run on renewable energy; and directly removing carbon from the air. Cutting emissions from existing electric power stations with CCUS could be made more appealing in a future with a circular carbon economy, in which captured carbon could be resold and recycled for other uses——for instance, serving as a raw material for making concrete or plastics.

    The basic idea of carbon capture has faced a lot of opposition. Skepticism has come from climate change deniers, who see it as a waste of money, and from passionate supporters of climate action, who fear that it would be used to justify continued reliance on fossil fuels. Both groups are ignoring the recent advances and the opportunity they present. By limiting investment in decarbonization, the world will miss a major avenue for reducing emissions in a variety of industries. CCUS can also create jobs and profits from what was previously only a waste material by creating a larger economy around carbon.

    The transition to clean energy has become necessary. But that transition's ability to achieve deep decarbonization will become less effective without this wide range of solutions, which must include CCUS.

    Mark Elliot Zuckerberg was born on May the 14th, 1984. He is the creator of the social media site Facebook. He was a star student at school, winning prizes in astronomy, maths and physics. He was also good at Classical studies. He studied Psychology and Computer Science at Harvard University, which is where he created Facebook. His invention led to his becoming Time magazine's Person Of the Year for 2010.

    Zuckerberg excelled in everything he did in his youth. He was captain of the school fencing team, spoke many languages and was a highly skilled computer programmer. While other kids played computer games, he designed them. He created his first network while in high school to connect all of the computers - in his father's dental surgery. He also built a media player which attracted the interest of Microsoft and AOL.

    Zuckerberg started at Harvard in September 2002. In his first year, he created Facemash, a Facebook predecessor (前身), which let students select the college's best looking people from a selection of photos.

    He launched Facebook from his Harvard room in February 2004. It was the start of a rollercoaster ride that would connect half a billion people worldwide and make him the world's youngest billionaire.

    Mark Zuckerberg is now one of the most influential people on the planet. He has dined with the president of the USA and regularly attends global economic summits and technology conferences. He stated: "The thing I really care about is the mission, making the world open." In 2010, Zuckerberg signed a promise, in which he promised to donate at least half of his life wealth to charity.
