Sorry all for belated response, thanks for sharing your knowledge, its helpful. Rythm, I am not dishearten, rather honored :D. Thanks! Flip Flop, Himal NY, sd-man, thanks for the appreciation. Bio-technology is the forthcoming technology. Our neighbor India is advancing rapidly in this field. As we all know the deveolpment of a country indirectly means the technological advancemnet. India and China have proved that you don't have to start from basic science (Newtonian Era) to get technological advancement. A developing country like India is leading in the most advance modern day technology, computer software, where as china is leading in hardware. They are now fastest growing economies of the world because of the modern technology. Were we had political stablitiy, we would have gained a lot form computer technology as China and India did. It was our unfortune that came to play....... and we are heading towards the uncertain future ..... Now India is advancing in Bio-tech, and we are fighting with each other. Tomorrow India will lead in Bio technology as it is leading in computer software today. We are laging behind and will never be able to catch our neighbors..... Perhaps we don't know what we are missing.....I am sorry worried, how many times will will be missing the chance.... Anyways, my worry will take us nowhere. I have posted the article just because that was a breakthrough. Material science is merging with life science and scientists are tilting towards the study of "mind" which is the most sophesticated thing in universe. I have heard that nature/science areticles are not accessible to everyone so I will be posting that article for all. Thanks
