IPhone owners are vainer（虚荣）and spend more on clothes and grooming（仪容）than those who have BlackBerrys and Android phones, new research claims.BlackBerry owners earn the most and are more likely to have long-term relationships, while people with Android handsets are most creative and the best cooks.

    The study, carried out by TalkTalk Mobile, surveyed 2,000 owners of the three major smartphone brands to determine whether the choice of handset was an extension(延伸) of their personality. The study rated users in various walks of life using a point scoring system including personalities, daily habits and the type of industries they work in.

    Other results from the study found that people with an iPhone are more image conscious and generally consider themselves more attractive than those with other handsets. They are most likely to describe themselves as adventurous, bright and are most likely to work in media, publishing and education. They also believe their boss rates them highly. Apple owners also tend to have done more travelling and are the most active on social media sites.

    BlackBerry owners were found to be the least punctual(准时的), but despite putting in the least hours at work they are the most active phone user—sending more texts and making more calls in the average day than any other phone user. They are more social and have more friends overall. They also earn nearly two and a half thousand pounds a year more than other smartphone owners, with an average salary of $27,406. BlackBerry users classed themselves so loud and mainly work in the health, finance or property sectors. They were also found to drink more tea and coffee each day than any other phone user.

    Android owners were found to watch more TV than others and drink the most alcohol—consuming more in an average week than iPhone and BlackBerry drinkers. They have the most jobs in engineering, the government and public services and environmental services. They have the best manners and are more shy and relaxed than their counterparts.

    Dan Meader, Director of Mobile at TalkTalk, said,“Many of us have our mobile phones on us almost constantly so they do become an extension of us in many ways. It's interesting to see then how the choice in handset may reflect different aspects of personality and the results do show some unusual difference

    Children in the United States eat too much pizza that some researchers now argue the food should join the ranks of sugary drinks and fast food for the harm they do to health．

    In a new study, the researchers found that pizza is a large source of calories, saturated fat(饱和脂肪)and salt in children's diets．Children should not eat more than two slices of pizza for a meal，and should pair that with salad, rather than with another high-calorie food，the researchers concluded．

    “Parents should aim to control pizza consumption(消费), particularly as a snack where it was shown to have a very adverse impact on children, and they should put their pizza dollars toward healthier brands．”Said Lisa Powel, director of the Illinois Prevention Research Center．

    Pizza has become a matter of focus in recent years for researchers who look at the meals children eat, rather than the nutrients within them．Studies have found pizza is among the greatest sources of calories for children．

    “Since pizza remains a common part of children's diet, we need to make 'healthy' pizza．”Powel said．To make pizza healthier, food producers should reduce its saturated fat and salt, and increase its whole grain content,” she said．

    Whether or not pizza is harmful enough to be picked out as an unhealthy food, the study attracts attention to a larger issue with the modern American lifestyle, said Alexis Tindall, who was not involved in the flow research. “Many foods are eaten too frequently and in large sizes,” said Tindall．To solve the problem, people don't have to give up eating pizza, but instead, they can eat smaller and healthier pizza，”she said．

    “Make it at home, instead of ordering it out where you don't have any control over how it's made.” Tindall said. “When we make it at home, we can choose healthier ingredients，increase the vegetables, reduce fat, and put in less cheese．Pizza doesn't have to be just pepperoni(意大利辣香肠)and cheese．”

    They may be teenagers, but 17-year-old Brittany Bull and 16-year-old Sesam Mngqengqiswa have grand ambitions(雄心) — to launch Africa's first private satellite (卫星) into space. They are part of a team of high school girls from Cape Town, South Africa, who have designed and built equipment for a satellite that will orbit over the earth's poles scanning Africa's surface.

    Once in space, the satellite will collect information on agriculture, and food security within the continent. Using the data/we can try to determine and predict (预测) the problems Africa will be facing in the future”, explains Bull, a student at Pelican Park High School.“Where our food is growing, where we can plant more trees and vegetation and also how we can monitor remote areas,” she says. “We have a lot of forest fires and floods but we don't always get out there in time.'' Information received twice a day will go towards disaster prevention.

    It's part of a project by South Africa's Meta Economic Development Organization (MEDO) working with Morehead State University in the US.

The girls (14 in total) are being trained by satellite engineers from Cape Peninsula University of Technology, in an effort to encourage more African women into STEM (science, technology, engineering, mathematics).

    Scheduled to launch in May 2017, if successful, it will make MEDO the first private company in Africa to build a satellite and send it into orbit.

    Mngqengqiswa comes from a single parent household. Her mother is a domestic worker. By becoming a space engineer or astronaut, the teenager hopes to make her mother proud. “Discovering space and seeing the Earth's atmosphere, it's not something many black Africans have been able to do, or get the opportunity to look at I want to see and experience these things for myself,” says Mngqengqiswa.

    Her team mate Bull agrees, “I want to show to fellow girls that we don't need to sit around or limit ourselves. Any career is possible-even aerospace.”

    We are currently on a camp site near Calais, on our way to the UK, and it is pouring with rain. As if gods want to prepare us for the UK at all costs. As if we don't know what rain is… Our ferry to the green isles will leave tomorrow at 10: 30 and despite the rain, I am really looking forward to it.

    It has taken us a while to get here, as we already left EI Chorro on 4 April. After rushing through Spain in two days, however, we came to an inevitable slow-down when we entered France. Inevitable, as France has simply too much to offer for us, so as soon as we crossed the Pyrenees, our driving sequence became something like driving a few kilometres, visiting a castle, driving a few kilometres, taking pictures of a nice church, driving a few kilometres, having a quick peek at a flea market, driving a few kilometres, visiting a museum etc. When we entered Brittany the real sightseeing started, in Vannes, in Lorient, in Brest and then on to Normandy: Le Mont St Michel, Bayeux and finally, finally the D-Day beaches. I always wanted to visit these, for obvious reasons I would say, but my father, realistic as he was, calculated the chances that it would rain a considerable amount of days of a three-week holiday and always decided against it. But a few days ago I finally stepped onto Gold Beach (where the Brits landed) and I was greeted by the Norman sun. A beautiful day.

    A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech integrated systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.

    "It's extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components," said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go-ahead to start piecing together the components. "The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own," he said.

    They engineered a series of systems to start and drive the robotic fly. "The seemingly simple system which just moves the wings has a number of interdependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything it's connected to," said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.

    While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers' fields or on the battlefield. "Basically, it should be able to take off, land and fly around," he said.

    Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications. "You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead," he said. "So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day to day basis."
