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.”

A dog spent the last four years of his life waiting a crossroad in the Thai city of Khon Kaen as if waiting for someone. People originally thought the dog had been abandoned, but then realized that he looked healthy, so people asked around about him. It turned out that the dog had indeed been spending most of his time around that crossroad, but a woman had been coming round regularly to bring him food and water.
One day, while photographing the dog everyone called Leo, a reporter met the woman who had been taking care of him. She had come to drop off some food.

A set of textbooks designed to help high school students learn about traditional Chinese culture is to be published soon Beijing Times reported on Monday.
The books are the first national-level works of their kind and have been developed by a working group that promotes traditional culture. They will be used by students from autumn this year the report said.
The set contains four classics from ancient times. Two of the works Confucian Analects and Mencius are for 10 th -grade students while the other two Great Learning and Dao De Jing will be used by 11 th graders.
The initiative follows a series of steps the authorities have taken in recent years to spread and promote traditional Chinese culture on campus.
Last April the Ministry of Education released a series of guidelines requiring the inclusion of more information about traditional culture in primary and middle school textbooks especially those used for subjects such as Chinese language history art and physical education.
The guidelines said students’ knowledge of traditional culture will be tested in the senior high school entrance examination and the gaokao --- the college entrance exam.

A great many parents send their children to pre-schools - educational programs for children under the age of five. It has been said that this is the time period when the brain does over fifty percent of its growing. This could mean that the learning process should be introduced during these years.
However, the views that different societies hold regarding the purpose of early childhood education are not same. Whereas Chinese parents tend to see preschools primarily as a way of giving children a good start academically, parents in the United States regard the primary purpose of preschools as making children more independent and self-reliant.
Preschools can operate under a guiding philosophy of play-based or academic learning. Play-based programs are guided by the central belief that children learn best through play. Play is thought to build children’s interest and love of learning. Academic programs emphasize reading, math and science, and use structured, teacher-directed activities to promote foundational skills in these areas. In the United States, the best-known program designed to promote future academic success is Head Start. The program, which stresses parental involvement, was designed to serve the “whole child”, including children’s physical health, self-confidence, social responsibility, and social and emotional development.
A recent evaluation suggests that preschoolers who participate in Head Start are less likely to repeat grades, and more likely to complete school in future. Furthermore, graduates of Head Start programs show higher academic performance at the end of high school, although the gains are modest. In addition, results from other types of preschool readiness programs indicate that for every dollar spent on the program, taxpayers saved seven dollars by the time the graduates reached the age of 27.
Not everyone agrees that programs that seek to enhance academic skills during the preschool years are a good thing. In fact, according to developmental psychologist David Elkind, United States society tends to push children so rapidly that they begin to feel stress and pressure at a young age. Elkind argues that academic success is largely dependent upon factors such as inherited abilities and a child’s rate of maturation, which parents can do nothing about. Consequently, children of a particular age cannot be expected to master educational material without taking into account their current level of cognitive development. In short, children require development appropriate educational practice, which is education that is based on both typical development and the unique characteristics of a given child.

One morning, when Gregor Samsa woke from troubled dreams, he found himself transformed in his bed into a horrible insect. He lay on his armor-like back, and if he lifted his head a little he could see his brown belly, slightly domed and divided by arches into stiff sections. The bedding was hardly able to cover it and seemed ready to slide off any moment. His many legs, pitifully thin compared with the size of the rest of him, waved about helplessly as he looked.
“What’s happened to me?” he thought. It wasn’t a dream. His room, a proper human room although a little too small, lay peacefully between its four familiar walls. A collection of textile samples lay spread out on the table-Samsa was a travelling salesman-and above it there hung a picture that he had recently cut out of an illustrated magazine and housed in a nice, gilded frame. It showed a lady fitted out with a fur hat and fur scarf who sat upright, raising a heavy fur muff(暖手筒)that covered the whole of her lower arm towards the viewer.
Gregor then turned to look out the window at the dull weather. Drops of rain could be heard hitting the window, which made him feel quite sad. “How about if I sleep a little bit longer and forget all this nonsense,” he thought, but that was something he was unable to do because he was used to sleeping on his right, and in his present state couldn’t get into that position. However hard he threw himself onto his right, he always rolled back to where he was. He must have tried it a hundred times, shut his eyes so that he wouldn’t have to look at the floundering legs, and only stopped when he began to feel a mild, dull pain there that he had never felt before.
He thought, “What a heavy career it is that I’ve chosen! Travelling day in and day out. Doing business like this takes much more effort than doing your own business at home, and on top of that there's the curse of travelling, worries about making train connections, bad and irregular food, contact with different people all the time so that you can never get to know anyone or become friendly with them.” He felt a slight itch up on his belly; pushed himself slowly up on his back towards the headboard so that he could lift his head better; found where the itch was, and saw that it was covered with lots of little white spots which he didn’t know what to make of; and when he tried to feel the place with one of his legs he drew it quickly back because as soon as he touched it he was overcome by a cold tremble.
He slid back into his former position. “Getting up early all the time,” he thought, “it makes you stupid. You’ve got to get enough sleep. Other travelling salesmen live a life of luxury. For instance, whenever I go back to the guest house during the morning to copy out the contract, these gentlemen are always still sitting there eating their breakfasts. I ought to just try that with my boss; I’d get kicked out on the spot. But who knows, maybe that would be the best thing for me. If I didn’t have my parents to think about I’d have given in my notice a long time ago, I’d have gone up to the boss and told him just what I think, tell him everything I would, let him know just what I feel. He’d fall right off his desk! And it’s a funny sort of business to be sitting up there at your desk, talking down at your inferiors from up there, especially when you have to go right up close because the boss is hard of hearing. Well, there’s still some hope; once I’ve got the money together to pay off my parents’ debt to him-another five or six years I suppose-that’s definitely what I’ll do. That’s when I’ll make the big change. First of all though, I’ve got to get up, my train leaves at five.”
