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.

    When you are travelling in Thailand, which means of transport is the best choice?

    You can rent a variety of motorbikes or bikes in Thailand. It seems to be very popular in most of the beaches and islands along the places in the north. The most popular bikes are the little 125 cc Honda Dream which you can get for about 150 baht (铢) a day or as little as 3,000 baht per month, making it the cheapest way to tour Thailand for the people from other countries.

    Sometimes you will have to go somewhere by taxi. When you are in cities in Thailand, especially in Bangkok, always remember to get a taxi that is traveling on the roads. Some drivers outside hotels refuse to use the meter(计程表). They will ask a price which is several times the price when they use the meter!

    The quality of the roads in Thailand is generally pretty good, so renting cars is another way to get around. The big car rental companies may offer you slightly older cars at a very reasonable(合理的) price. It is a little surprising considering that the cost of buying a car in Thailand is more than that in the West. Petrol is also reasonably priced in Thailand, more expensive than American prices, but much cheaper than what is paid in Europe. In the past, Bangkok could be a difficult place to drive in—signs were generally in Thai only, making it a hard job to find exactly where you were by looking around. But now, the situation is improved. In a lot of places, even the farthest corners of the country, street signs are in both Thai and English.

    Poet William Stafford once said that we are defined more by the detours (绕行路) in life than by the narrow road toward goals. I like this image. But it was quite by accident that I discovered the deep meaning of his words.

For years we made the long drive from our home in Seattle to my parents' home in Boise in nine hours. We traveled the way most people do: the fastest, shortest, easiest road, especially when I was alone with four noisy, restless kids who hate confinement (限制) and have strong opinions about everything.

    Road trips felt risky, so I would drive fast, stopping only when I had to. We would stick to the freeways and arrive tired.

    But then Banner, our lamb was born. He was rejected by his mama days before our planned trip to Boise. I had two choices: leave Banner with my husband, or take him with me. My husband made the decision for me.

    That is how I found myself on the road with four kids, a baby lamb and nothing but my everlasting optimism to see me through. We took the country roads out of necessity. We had to stop every hour, let Banner shake out his legs and feed him. The kids chased him and one another. They'd get back in the car breathless and energized, smelling fresh from the cold air.

    We explored side roads, catching grasshoppers in waist-high grass. Even if we simply looked out of the car windows at baby pigs following their mother, or fish leaping out of the water, it was better than the best ride down the freeway. Here was life. And new horizons (见识).

    We eventually arrived at my parents' doorstep astonishingly fresh and full of stories.

    I grew brave with the trip back home and creative with my disciplining technique. On an empty section of road, everyone started quarreling. I stopped the car, ordered all kids out and told them to meet me up ahead. I parked my car half a mile away and read my book in sweet silence.

    Some road trips are by necessity fast and straight. But that trip with Banner opened our eyes to a world available to anyone adventurous enough to wander around and made me realize that a detour may uncover the best part of a journey—and the best part of yourself.

    Would it surprise you to learn that, like animals, trees communicate with each other and pass on their wealth to the next generation?

    UBC Professor Simard explains how trees are much more complex than most of us ever imagined. Although Charles Darwin thought that trees are competing for survival of the fittest, Simard shows just how wrong he was. In fact, the opposite is true: trees survive through their cooperation and support, passing around necessary nutrition “depending on who needs it”.

    Nitrogen (氮) and carbon are shared through miles of underground fungi (真菌) networks, making sure that all trees in the forest ecological system give and receive just the right amount to keep them all healthy. This hidden system works in a very similar way to the networks of neurons (神经元) in our brains, and when one tree is destroyed, it affects all.
     Simard talks about “mother trees”, usually the largest and oldest plants on which all other trees depend. She explains how dying trees pass on the wealth to the next generation, transporting important minerals to young trees so they may continue to grow. When humans cut down “mother trees” with no awareness of these highly complex “tree societies” or the networks on which they feed, we are reducing the chances of survival for the entire forest
   “We didn't take any notice of it.” Simard says sadly. “Dying trees move nutrition into the young trees before dying, but we never give them chance.” If we could put across the message to the forestry industry, we could make a huge difference towards our environmental protection efforts for the future.

    On June 23, 2010, a Sunny Airlines captain with 32 years of experience stopped his flight from departing. He was deeply concerned about a power part that might run out of all electrical power on his trans-Pacific flight. Regardless of his concerns, Sunny Airlines pressured him to fly the airplane over the ocean at night. When he refused to put the safety of his passengers at risk, Sunny Airlines' Security removed him out of the airport, and threatened to arrest his crew if they did not cooperate.

    Besides that, five more Sunny Airlines pilots also refused to fly the aircraft, expressing their own concerns about the safety of the plane. It turned out the pilots were right: the power part was faulty and the plane was removed from service and finally fixed. Eventually a third crew operated the flight, hours later. In this whole process, Sunny Airlines pressured their highly experienced pilots to ignore their safety concerns and fly passengers over the Pacific Ocean at night in a plane that needed maintenance. Fortunately for all of us, these pilots stood strong and would not be frightened.

    Don't just take our word. Please research this yourself and learn the facts at www.SunnyAirlinePilot.org. Once you review this shocking information, please keep in mind that while their use of Corporate Security to remove a pilot from the airport is a new procedure, flight crews' lacking confidence is becoming common at Sunny Airlines, with recorded events occurring on a weekly basis.

    The flying public deserves the highest levels of safety. No airlines should maximize their gains by pushing their employees to move their airplanes regardless of the potential human cost. Sunny Airlines' pilots are committed to resisting any practices of damaging your safety for profits. We've been trying to deal with these problems behind the scenes for quite some time; now we need your help. Go to www.SunnyAirlinePilot.org to get more information and find out what you can do.

    Walk through the Amazon rainforest today and you will find it steamy, warm, damp and thick. But if you had been there around 15,000 years ago, during the last ice age, would it have been the same? For more than 30 years, scientists have been arguing about how rainforests might have reacted to the cold, dry climate of the ice ages, but till now, no one has reached a satisfying answer.

    Rainforests like the Amazon are important for mopping up CO2 from the atmosphere and helping to solve global warming. Currently the trees in the Amazon take in around 500 million tons of CO2 each year: equal to the total amount of CO2 given off in the UK each year. But how will the Amazon react to the future climate change? If it gets drier, will it survive and continue to draw down CO2? Scientists hope that they will be able to learn in advance how the rainforest will manage in the future by understanding how rainforests reacted to climate change in the past.

    Unfortunately, collecting information is incredibly difficult. To study the past climate, scientists need to look at fossilized pollen (花粉) kept in lake mud. Going back to the last ice age means drilling down into lake sediments (沉淀物), which requires specialized equipment and heavy machinery . There are very few roads and paths, or places to land helicopters and aeroplanes. Rivers tend to be the easiest way to enter the forest, but this still leaves vast areas between the rivers completely unsampled (未取样). So far, only a handful of cores have been drilled that go back to the last ice age and none of them provide enough information to prove how the Amazon forest reacts to climate change.
