While I have been webmastering and blogging for over one and half years, I am no techie by any means of imagination. My computer or technological knowledge is just minimal to the point of 9 months diploma in computer application and some very basic knowledge on programming. And believe me, quality blogging is a laborious job and one has to constantly update his own knowledge by reading and looking for information.

So I chanced upon one of my friend who was involved in selling embedded computer. I was shocked as I never heard of them. Then he explained that there are some computers dedicated to perform some specific jobs like particular industrial functions. These computers come with RFID readers (Radio-Frequency Identification) which are tiny electronic items consisting of tiny chips and antennae and work as identifier of tags and capture data automatically. These RFID readers have definitely become very important part of modern electronic technology along with transponders. Transponders have long been regarded as the backbone of electronics technology. RFID devices come in many forms such as PC cards, OEM boards and also have different frequencies. On the other hand transponders are electronic equipments which receive signals, convert them to new frequencies and then transmit them to new location.

I never knew these devices in details and now I am much wiser than before.

Few days back I visited the neighborhood I grew up and found it quite than those days I spent my childhood. There are still same people, same building except that their outer look changed with age. I caught up with some childhood friends and after talking to them came to know why the area has become so quiet.

I grew up going to the nearby game plaza during the weekend and spent all my weekly pocket allowances there. As soon as the plaza opened, it became a raze for children and big headache for guardians. We were amazed with virtual reality games by SEGA and drove speed-boat at high speed without fear of getting hurt or worse killed.

But now the situation has changed with the advent of internet and new technologies. With the exponential growth of internet and unimaginable advancement in technology including 3D, flash and graphics – companies have developed innumerable number of exceptional games and offer them free online. People have become so fond of free online games that they are now spending more time in front of their monitors than somewhere else. Its not children, but more adults have become online games addicts. And why should not they be? After all the advent of broadband internet, crystal clear graphics and sound system have made playing games an unforgettable experience. One can easily play classic games such as PacMan, Tetris, Battleships etc. along with sport games like Virtual Champions League, Beachtennis, Baseball and much more.

To be frank even I am an online game junky, often logging on to my favorite game site. Only future will tell if this too will change in ten years time!

In a landmark breakthrough in the field of bio-technology or bio-medicine, scientists have been able to bring life to a death hearth, albeit that of a rat.

According to Nature Medicine the premiere journal of biomedical research, scientists at the University of Minnesota stripped a dead heart of all its cells using detergents and left only the scaffold made up of connective fibres and tissues. Then they injected the decellularised scaffold with 50-70 million living cells from newborn rats allowing them to grow on the scaffold. The new cells grew on the scaffold and the heart began to contract in four days time. The heart begun to show pumping activity in eight days.

This scientific breakthrough has opened unlimited opportunity for scientists to perfect the technique and try to apply it on human heart. It has been revealed that scientists have also tried this decellularization technique on other organs such as liver, lung, kidney and the pig hearth which is more closer to human hearth in size and complexity.

But scientists caution that it is still miles to go before human organs can be made through this technique. The organs have not yet been used for on animals for practical demonstration of how they work.

One obvious hurdle is the number of living cells required for seeding the scaffold under the technique. In this case, living cells from 100 rats have been used and naturally, the question arises from where would these cells be found in case of seeding a dead human organ to bring it to life. Stem Cells are the likeliest solution as they can turn into any type of cells in the body. Scientists hope that solutions can be found in the near future and these bioartificial organs can be alternative to organ transplantation procedures. According to estimates, around 22 million people suffer from heart failure every year.

With the arrival of the season of winter, we need some extra effort to decorate our interior. It is very cold in out side. To keep our body worm we use blazer and leather jacket etc. At the beginning of the civilization when men live in the cave they used to ware nothing to protect them from the winter. Human are separate from other animal. They don’t have the thick skin or lots of hair to protect them from extreme cold. At fast the tree skin are used as the body shields and then they use the skin of the hunted animal to protect body from cold. The use of cotton and making cloth has change the living of human more comfortable. Like other technology, the textile technology grows up from the early use of hand loom. If we think the evolution of any kind of technology we will find every technology star with very sample tool. The innovation of wheel is responsible for today’s formula 1 (one) automotive. To protect the body from cold we use the theory of insulator. Any matter that stops transmission of heat energy from one end to other end is known as an insulator. Wool is a one of the best insulator and better than any other artificial fabric to use as an insulator. Wool is a natural fabric. Synthetic fibers can’t be an alternative for wool. Traditional technology are use in making wool made rugs and other winter clothing. Using those tradition rugs and other durable carpeting is an eco-friendly attitude. For synthesis of Synthetic fibers we use different kind of chemicals. These chemicals from textile industry are a vital cause of water and air pollution. This is also harmful for agriculture and eco-system of the earth. The traditional technologies are sometime more eco- friendly. It absorbs the unnecessary sounds and keeps the room from the noise pollution by the sound reservation process.

An lcd tv is something everyone wants today. It all began with lg phones coming with their own memory cards. That produced the need of lcd monitors. Later samsung phones also adopted the technology with the better quality of transformers.
