Destructive And Productive Inventions Of 2011

The American administration wants to maintain its military supremacy in the world with which it can remain a superpower. Due to this madness of the USA, drone X-47b was invented during 2011.
Though it is a unmanned drone but it is a complete war plane too. It does not need experts for its flight on the ground even, the modern computerized system makes it fly and are controlled by computers rather than any person. Americans built it for deploying on marine plane carriers. It will be sent for bombardment to enemy forces. It ha been built with stealth technology to hide it from enemy's radars due to its huge size. It is sub-sonic and can fly on a speed over 500 miles per hour. Thus Americans have invented another fatal plane to attack and eliminate human beings. The drone will be handed to navy next year.
*---- Movement By Thinking Power
Experts have already invented such mechanical hands and arms during the last 10 years that move with the power of thinking. The electronic contact of arms is with the brain controlling the movements. In the terminology of nerve's science this process is called brain-machine interface. But the problem with this process is that orders are one sided, they are transmitted from brain to mechanical hands but do not return. Though mechanical hand moves but has no sense of touching. To remove this fault scientists are trying to invent brain-machine-brain interface.
The researchers of Duke University Medical Center in American city Darham conducted an unique experiment. They installed electrodes in the brains of two monkeys and taught them that how they have to pick things without moving hands and legs through the virtual hand present in the computer.
One set of the electrodes was installed in the "motor cortex" part of the brain that controls movements and the other set was installed in the "lomoto sensory cortex" where the data coming from the cells is processed that create sense of touch. Thus it was made possible that the orders coming from the brains of monkeys to the machine(computers) return back.
Now researchers kept three things resembling each other in the computer screen before the monkeys. Among these three things one was that when it was touched by the computer's hands would create sense of touch by the electrodes. Monkeys were again taught to touch the thing that creates sense. When monkeys were successful in touching the target they were presented fruits. After some practice monkeys succeeded continuously touching the right thing.
Thus scientists succeeded in conducting the first brain-machine- brain experiment. Monkeys got success in touching the right target on computer screen through the power of thinking. The experiment opened the way for making such hands, legs and other body parts in future that would be controlled by the power of thinking. Such body parts will enable the paralyzed people to move and this will be a revolutionary achievement of science.
