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.

     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.

    Is there link between humans and climate change or not? This question was first studied in the early 1900s. Since then, many scientists have thought that our actions do make a difference. In 1997, the Kyoto Protocol explained our role in the Earth's changing atmosphere and set international limits for gas emissions(排放) from 2008 to 2012. Some countries have decided to continue these reductions until 2020. More recently, the Paris Agreement, stuck by nearly 200 countries, also aims to limit global warming. But just now how much warmer it will get depends on how deeply countries cut carbon emissions.

    A creative mom Danielle Lindemann is a mother to a soon-to-be 3-year-old daughter. When she received the Disney-brand book What Is A Princess? as a gift for her daughter, Lindemann thought the messages seemed a little shallow.

Lindemann's efforts included changing “A princess is kind” to “A princess is kind of a badass” and completing the sentence “A princess likes to dress up”. “I just want my daughter to see that she can be anything she wants,” the mom explained, “She can also speak her own mind and be a doctor or a senator if she wants.”

    After Lindemann made the changes, she thought her daughter might be a bit confused, but the daughter actually just rolled with it. Lindemann did not intend for many people to see her edits. She just found it amusing. Though she didn't imagine having such a wide audience, Lindemann says she thinks it's great if her edits make people smile or even think a bit differently about gender models.

    Further, Lindemann added, “there is absolutely nothing wrong with girls (or boys!) wanting to put on something sparkly and feel pretty. But when the ruling idea is that girls — and women — are judged mainly on their physical appearance in a way that boys and men are not, I think it's important to model some other values for these girls as well.”

    As a parent, she believes it's important to show girls that their worth does not lie only in their physical appearance and that their other qualities are valuable and important. For her, if there were a variety of children's books out there in which little girls were shown playing with trucks and trains and learning to be engineers and surgeons, and if there were books out there in which boys were shown getting a kick out of dressing up in fancy clothes, it would be a different world.

     “At present, it's not that world. But time will tell,” she stressed.

    I will never forget the days when I met with my classmates. Early in the morning of our first school day, our professor introduced himself and challenged us to get to know someone we didn't know yet. I stood up look around when a gentle hand touched my shoulder. I turned round to find a wrinkled, little old lady beaming up at me with a smile that lit up her entire being.

    She said, “Hi handsome. My name is Rose. Can I give you a hug?”

    I laughed and enthusiastically responded, “Of course you may!” and she gave me a giant squeeze.

    “Why are you in college at such a young, innocent age?” I asked.

    She jokingly replied, “I'm here to meet a rich husband, get married, and have a couple of kids…”

    “No seriously,” I asked. I was curious what may have motivated her to be taking on this challenge at her age.

    “I always dreamed of having a college education and now I'm getting one!” she told me.

    After class we shared a chocolate milkshake. We became instant friends. Every day we would leave class together and talk nonstop. I was always mesmerized（迷住）listening to this “time machine” as she shared her wisdom and experience with me.

    At the end of the semester we invited Rose to speak at our football banquet. I'll never forget what she taught us.

    “There is only one secret to staying young. You've got to have a dream. When you lose your dreams, you die. We have so many people walking round who are dead and don't even know it! There is a huge difference between growing older and growing up. If I am eighty-seven years old and stay in bed for a year and never do anything I will turn eighty-eight. Anybody can grow older. That doesn't take any talent of ability. The idea is to grow up by always finding opportunity in change. Have no regrets. The elderly usually don't have regrets for what we did, but rather for things we did not do. The only people who fear death are those with regrets.”

    She concluded her speech by courageously singing The Rose. She challenged each of us to study the lyrics and live them out in our daily lives.

    People with bigger brains tend to score higher on standardized tests of intelligence, according to new study findings.

    However, the study author Dr. Michael A.McDaniel of the Virginia Commonwealth University in Richmond emphasized that these findings represent a general trend, and people with small heads should not automatically believe they are less intelligent. For instance, Albert Einstein's brain was "not particularly large", McDaniel noted." There's some relationship between brain size and intelligence on the average, but there's plenty of room for exceptions," he said.

    Interest in the relationship between brain size and intelligence grew in the1830s, when German anatomist(解剖学家) Frederich Tiedmann wrote that he believed there was "an unquestionable connection between the size of the brain and the mental energy displayed by the individual man". Since that statement, scientists have conducted numerous studies to determine if Tiedmann's assertion was correct. Most studies have looked into the link between head size and intelligence. More recently, however, researchers have published additional studies on brain size and intelligence, measured using MRI scan(核磁共振成像扫描).

    For his study, McDaniel analyzed more than 20 studies that looked into the relationship between brain size and intelligence in a total of 1,530 people. The studies showed that on the average, people with larger brain volume tended to be more intelligent. The relationship between brain volume and intelligence was stronger in women than men, and in adults than in children. McDaniel notes in the journal Intelligence.

    McDaniel is not sure why the relationship was stronger for adults and women. "Other research has shown that women, on the average, tend to have smaller brains than men, but score just as well—if not higher—in tests of intelligence," he said.

    McDaniel insisted that the relationship between brain size and intelligence is not a "perfect" one. "One can certainly find lots of examples of smaller-sized people who are highly intelligent," he said, "But, on the average, the relationship holds."
