This piece of news is presenting a kind of hormone found sensitive to fat cells when the sullen procedure in the human body is blocked. It may supersede sullen as a new medicine to cure diabetes.
The sharp of cities to come
The data received by satellite shows that between 1999 and 2009, big cities on earth were changing rapidly. Chinese cities grow vertically, echoing to the expansive ground price, while African cities expend their space to larger and larger, owing to the height limitation and the unutilized vast field.
Deprivation: A wake-up call
The article puts forward a series of experiments about the passive impacts that inefficient sleep causes, that people who sleep less than 7 hours risk more to diabetes, obesity, heart attack and other diseases, while more than 9 hours a higher glucose content. Moreover, unfortunately, the demerits and impairments caused by partial deprivation of sleep could not be compensate by other vehicles.
Perspective: Casting Light on Sleep Deficiency
After the invention of electric lights by Edison, nights have been illuminated by LEDs and other lights, especially in cities. Unlike the assertive statement by him, lights may be not so innocent to harm our bodies. Light disguises the mid-night and together with the awake hormone that ironically high at the end of the day, we turn to TVs and bars instead of beds. Excluding the earlier getting-up time and the colorful entertainments, we should also cast attention to the light pollution as an accomplice to our sleep deficiency.
This essay is focusing on a institution named Adaptive Actions initiated in London, concerning the different behaviors in public spaces and enriching it by the comprehensive instruction of a program held by it, which provides a space for people to record their behaviors online.
According to this news, a experiment of cells take-out is successful these days and thus storms a heated debate about the ethnical dilemma since last century the time when first colone sheep came into being. The author is positive about the medical prospect, while still worry about problems underground.
Cheap, Flexible,White Light
Scientists find a substitute of original material consisting LEDs. Making them with microwires placed in transparent plastic can solve the problem of emitting at varied angles.
Multiplexed mouse mutations
Mutations on mice could be easily controlled by means of bacteric proteins and targeted RNA,according to a successful experiment by Britain scientists.
Cosmic rays show how boulders move
It is possible now to investigate the movement and erosion of rocks by testing the isotopes caused by cosmic rays. Since rocks are always useful for us to know the age, it is helpful to help us to tract the geological events in the river of time.
It is an introductive article full of specific examples and experiences of Student Quality Circle (SQC) in different countries, a group that bottom-up, self-control, and focused on both individual improvement and mutual improvement. The ideal of SQC is to provide a visual workshop for students to study together and help each other, but it also helps to maintain the solidarity of society.
Gold
As a brief instruction of editorials presented below, this short passage introduce the use of gold in our life, not only gold rings as a promise to share two hearts and gold medals as we all know, but also economic issues concerned with this metal and what’s more, some chemical and technique secrets we may be not so familiar.
Photonics: trick of the light
In this article, the author shows us a myriad of progress in varied fields brought by the photonic characteristic of gold. Beginning with a cup of 18th century that could change its color from green to red exposed in light, we are led to a golden world. For instance, biological sensors could be more sensitive equipped with gold micro wires, as well as the transparent window glass, on which very small piece of gold could contribute to absorption to all the light emitting to it. Furthermore, it is also cheaper and simpler to use it as an amplitude instrument beyond our imagination. And gold can also shows its superiority in computer science to help information to get through ways smaller than light’s wavelength.
More cyclones of Hawaii Island
Owing to the climate change on earth, it is predicted that there will be double cyclones reaching to Hawaii in 2075-99 comparing with ones in 1979-2003. As the earth is getting warmer and warmer, the cyclones formed above Mexico would easily reach to islands in Pacific Ocean, even though the number is less.
This article is written to show some intensive relationships of China with countries like India and Japan just around. While China is having such a sovereign conflict about Diaoyu Island with Japan that both countries sent army to this pearl in the Pacific Ocean, at the same time, the vague territory line just between China and India is not quiescent as well. What’s more, the acclamation of Beisha archipelago, too, causes some Asian countries upset. The author supposes that if Chinese diplomatic officers are not lacking of experience to handle things one after another, it could be probably that a claim by China for its land (and sea) power as an empowering country. At last, the author is worrying about this conflict to evolve into violence, considering America’s behalf of defending Japan.
A new country rise from the ruins
Looking down, South Sudan seems rising from bush. This new country is facing with problems covering politics, borders, economics, technique, ethical dilemmas and everyday life of normal people in Sudan, in which 90% are illiterate and large amount of them prefer sending their children to the fields instead of school partially owing to poverty. It seems that there is still a long way for this youngest country to go, until it fulfills its claim, to independence and liberty.
3-D printing windpipe give the infant breath of life
A 3-D print tissue helps to keep open the airway of a little boy who suddenly fell ill and unable to breath and saves his life accompanied with a detailed description of this new technology.
