Young children from poor families are more likely to consume junk food and fizzy drinks(汽水) than their richer companions. A study of 1,800 four- and five-year-olds found more than half of those from poor backgrounds drank at least one a week, compared to just four in ten oofy kids. They also drank less milk and consumed more fruit juice which is also linked to child obesity (肥胖) caused by high sugar intake(摄取量).

    The phenomenon also relates to children who spend more than two hours a day in front of a TV or playing computer games—whatever their social circumstances. A companion study also found children from poor families were more likely to eat chips, sweets and chocolate. Professor Kate Storey said, “when you are looking at that age group, and such a large percentage of very young kids in the study are consuming a large amount of soda(苏打汽水)，it is quite concerning. ”

    The researchers carried out the study by surveying the parents of their participants to find out their dietary habits. Professor Storey said, “If you are drinking a lot of soda and fruit juice, they can displace(取代)consumption of water and milk, which are important not just for ending thirst, but for developing healthy bones and teeth, and health and wellness in general.”

    Co-researcher Dr John Spence said, “Dietary behavior and intake patterns are influenced heavily by what happens in the first few years with children, and they maintain those patterns throughout childhood and into adolescence(青少年时期).” In addition to basic health education, this study identifies a need in how we are dealing with poverty and recognizing there is more to poverty than simply the number of dollars people have.

    Professor Storey said that shows how education can make a difference and lead to healthier eating habits, regardless of what is happening at home. “Many families live in places that might not be very healthy for them and, as a result, they make unhealthy food choices. You can start making a difference in different places. It calls for action in multiple settings, schools and communities, for example. That light-bulb moment can happen in a variety of places,” Professor Storey added.

    You're not doomed to toss and turn every night. Although you might not be able to control all of the factors that relate to your sleep, you can adopt habits that encourage better sleep. Start with these simple sleep tips.

    No. 1: Stick to a sleep schedule

    Go to bed and get up at the same time every day, even on weekends, holidays and days off. Being consistent reinforces （加强） your body's sleep-wake cycle and helps promote better sleep at night. If you don't fall asleep within about 15 minutes, get up and do something relaxing. Go back to bed when you're tired.

    No. 2: Pay attention to what you eat and drink

    Don't go to bed either hungry or stuffed. Your discomfort might keep you up. Also limit how much you drink before bed, to prevent disruptive middle-of-the-night trips to the toilet. Nicotine, caffeine and alcohol deserve caution, too. The stimulating effects of nicotine and caffeine — which take hours to wear off — can ruin quality sleep.

    No. 3: Create a bedtime ritual

    Do the same things each night to tell your body it's time to wind down. This might include taking a warm bath or shower, reading a book, or listening to light music. Be careful of using the TV or other electronic devices as part of your bedtime ritual. Some research suggests that screen time or other media use before bedtime has impact on sleep.

    No. 4: Get comfortable

    Create a room that's ideal for sleeping. Often, this means cool, dark and quiet. Consider using room-darkening shades, earplugs, a fan or other devices to create an environment that suits your needs.

    Your mattress and pillow can contribute to better sleep, too. Since the features of good bedding are subjective, choose what feels most comfortable to you. If you have children or pets, set limits on how often they sleep with you — or insist on separate sleeping quarters.

    No. 5: Limit daytime naps

    Long daytime naps can affect nighttime sleep — especially if you're struggling with poor sleep quality at night. If you choose to nap during the day, limit yourself to about 10 to 30 minutes and make it during the mid-afternoon.

If you work nights, you'll need to make an exception to the rules about daytime sleeping. In this case, keep your window coverings closed so that sunlight — which adjusts your internal clock — doesn't interrupt your daytime sleep.

    No. 6: Include physical activity in your daily routine

    Regular physical activity can promote better sleep, helping you to fall asleep faster and to enjoy deeper sleep. Timing is important, though. If you exercise too close to bedtime, you might be too energized to fall asleep. If this seems to be an issue for you, exercise earlier in the day.

    No. 7: Manage stress

    When you have too much to do — and too much to think about — your sleep is likely to suffer. To help restore peace to your life, consider healthy ways to manage stress. Start with the basics, such as getting organized, setting priorities and dividing tasks. Give yourself permission to take a break when you need one. Share a good laugh with an old friend.

    Nearly everyone has an occasional sleepless night — but if you often have trouble sleeping, contact your doctor. Identifying and treating any underlying causes can help you get the better sleep you deserve.

    Once upon a time there were two friends who lived in a palace and worked in the service of the king. One of the two boys knew a girl he liked so much that he wanted to give her a present.

    One day, when he was walking with his friend in the main palace hall, he saw a big vase filled with the most beautiful flowers. He decided to take one to give to the girl, thinking that no one would see him do so except his friend. He did the same thing the next day, and the next, and the next... until, one day, the king noticed how few flowers were left in the vase. He was so angry that he called everyone in the palace to come together in the hall.

    When they were all before the king, the boy thought he should say it was he who had taken the flowers. However, his friend told him to be quiet, because the king would be terribly angry with him. The boy was filled with fear, but when the king came near, he decided to confess.

    As soon as the boy said that he had done it, the king went red with anger, but on hearing what the boy had done with the flowers, a smile appeared on the king's face, and he said, “I couldn't have thought of a better use for my flowers.”

    And from that day, the boy and the king became great friends. They went to the vase and took two of those wonderful flowers, one for the girl, and the other for the queen.

    Retired jet engines could help clear the smog that smothered big cities.

    To land at Indira Gandhi Airport is to descend from clear skies to brown ones. New Delhi's air is poisonous. According to the World Health Organization, India's capital has the most polluted atmosphere of all the world's big cities. The government is trying to introduce rules that will curb emissions-allowing private cars to be driven only on alternate days, for example, and enforcing better emissions standards for all vehicles.

    But implementing these ideas, even if that can be done successfully, will change things only slowly. A quick fix would help. And Moshe Alamaro, a researcher at the Massachusetts Institute of Technology, thinks he has one. His idea is to take a jet engine, put it next to one of India's dirty coal-fired power plants, point its exhaust nozzle at the sky and then switch it on. His hope is that the jet's exhaust will disrupt a meteorological phenomenon known as "inversion", in which a layer of warm air settles over cooler air, trapping it, and that the rising stream of exhaust will carry off the tiny particles of matter that smog is composed of. Inversion exacerbates air pollution in Delhi and in many other cities, from Los Angeles to Tehran. A particularly intense example caused the Great Smog of London in 1952, when four days of air pollution contributed to 12,000 deaths.

    Dr Alamaro thinks a jet engine could punch through the inversion layer to create a "virtual chimney" which would carry the trapped pollution above it, so that it could be dispersed in the wider atmosphere. He calculates that all the emissions from a gigawatt coal-fired power plant could be lifted away using a single engine with a nozzle speed of 460 metres a second.

    However, he has not calculated whether a jet engine could disrupt the inversion layer and allow the pollution to escape the city-so he is now going to test that hypothesis. Within eight months, Dr Alamaro plans to put one of his updrafters next to a coal-fired power plant and monitor what happens using a fleet of drones. He is in discussions with Tata Group, a conglomerate with an electricity-generating arm, to run it next to one of the firm's power stations.

    Scientists in Britain have managed to teach bees to pull strings (线) to get to food and then pass on what they have learned to others in their colony (群体) — showing a high level of intelligence despite their tiny brains.

    Researchers at Queen Mary University of London said the experiments, often used to test the intelligence of apes (猿) and birds, showed for the first time that some insects are up to the task, and can also pass skills on through several generations.

    The findings add to the evidence suggesting the ability for "culture spread"— the ability to learn and pass on knowledge and skills — may not be exclusive to humans.

    In the research, published in the journal PLOS Biology on Tuesday, the scientists were able to train 23 out of a group of 40 bees to pull strings with their legs and feet.

    The strings were attached to discs — or artificial "flowers"— containing food at their center but placed under a transparent (透明的) screen. The bees, spotting the food beneath the screen, learned to pull the "flowers" out by pulling the string with their legs and feet to be able to get to it.

    From another group of bees given the chance to solve the task without any training, only two of 110 were successful.

    Another group of bees was then allowed to observe the trained bees pulling the strings, and 60 percent of them successfully learned the skill. Finally, trained bees were put in colonies, and the scientists found the technique spread successfully to a majority of the colony's worker bees.

    Lars Chittka, a Queen Mary University professor who guided the project, said the team is interested in figuring out the brain processes behind the bees' learning and teaching skills.
