In less than twenty years, mobile phones have gone from being odd and expensive pieces of equipment used by businesses to an enveloping low-cost personal item. In a lot of countries, mobile phones now outnumber land-line telephones, with the majority adults and many children now owning mobile phones. In the United States, 50% of children hold the mobile phones. It is not uncommon for young adults to simply own a mobile phone instead of a land-line for their house. In some developing countries, where there is little existing fixed-line communications, the mobile phone has become extensive. According to the CIA World information book the UK now has extra mobile phones than people.
With high levels of mobile telephone access, a mobile culture has evolved, where the phone becomes a key social tool, and people rely on their mobile phone address book to keep in contact with their friends. Many people keep in touch by using SMS, and an entire culture of testing has developed from this. The commercial market in SMS is increasing. It is very useful for all the people.

A Nucleus a Day
Wow, one more exciting day is about to begin. Sometimes I get so exhausted of being the brains of this whole process, but it is fun to be the boss and give the orders. Lets study a usual day I am a nucleus. My life is very difficult because normal things going on and I hardly have a time to talk to you. But as I started telling you about me then my strength as well finish it up. I am the most significant organelle. It can be reduced in size by rapping it around a nucleosides arrangement of his tone proteins. The nucleus that is in me is the site for RNA and the covering of ribosomal subunits for export to the cytosol. The DNA string is sometimes a very long particle, and sometimes it needs to be compressed to fit into a certain spot. This can result in the DNA strand to be compact so it will fit in the space. Well cannot talk any longer but it was time to take a break. My primary purpose is to organize the actions inside the cell.

A simple Girl
Around and around it soared in brutal circles, tearing from side to side her animated temples. At a standstill, they did not do anything. Still, they simply laid there with faces of chalk, invalid of all human emotions. She could not look at them in hopes of relieve, for long. The cherry rivers that flowed across her eyes, streamed down her steaming cheeks, made vision impossible.
Life was simply the stack of decayed flesh that enclosed her. From his immortal lips hung the bodies of all those who died struggle for him and all those who had tampered with self luxury. For that, she dammed him for all eternity; in every form he understood she dammed him. He had been her guiding angle and now it became evident to her. No prayer would pass her conditions lips, for this had been his movement she had fought and they had lost other than just a clash.

Electron microscopes
Electron microscopes, which use beams of electrons as a substitute of light, are designed for very high magnification usage. Electrons, which have a much smaller wavelength than visible light, allow a much higher resolution. The main limitation of the electron beam is that it must pass through a vacuum as air molecules would otherwise scatter the beam.
