Scientists at London’s Guy’s and St. Thomas Hospital announced on March 3, 2013 the development of a revolutionary spinal implant that allows crippled parents to walk again. The new device will go a long way in benefiting people suffering from the agony of spinal injury. The implant is based on the principle of spinal cord stimulation, which works by disrupting and thereby drastically reducing pain signals to the brain. The technique involves implanting wires near the spinal cord, linked to a generator. This gives off high-frequency electrical impulses, which the patient does not feel.
The device has opened up a new avenue in pain reduction practices. It has so far been tested on people suffering from severe back and leg pain caused by spinal injuries. Experts, however, said that as the implant is completely free from side effects, it can also be used to treat other painful conditions such as migraine and nerve damage.

As per a report released on March 18, 2013, an England-based inventor has come up with the ultimate eco-friendly vehiclea car that runs on nothing but. cold air. The inventor, Mr. Peter Dearman, said that the car could reach speeds of up to 48 km per hour. The prototype he has built can presently run for a distance of five km at a stretch. The car will not produce any emissions because it is only air that is used in running it. It does not involve burning anything, just using heat from the atmosphere.
The propulsion system of the car is akin to that of a steam engine, the only difference being that the inventor uses very cold liquid air. At 190° Celsius, air turns into a liquid that can be stored in insulated, vacuum-sealed containers. Mr. Dearman uses a beer drum as a makeshift tank for the liquid air. When the air courses through the engine, it heats up from its cryogenic temperature and boils via a heat-exchange fluid (in this case, anti-freeze). Instead of using expensive heaters to heat the liquid fuel, the Dearman engine injects a mix of water and antifreeze (methanol) into the cylinder as the liquid air is drawn in, causing it to heat and expand rapidlythereby forcing the piston down inside the cylinder and driving the engine. It is a lot cheaper, more efficient and more compact than using heat exchangers.
The interview is meant to probe and evaluate your personality and not merely your knowledge. The application of your knowledge to reveal your personality in a positive manner will guarantee your sure success in die interview. This means, to begin with, you must acquire and have the knowledge in your possession. Knowledge never goes to waste. Knowledge is power and ideas rule the world.

The subject of die essay is a proverb which means that no work worth doing can be accomplished either easily or quickly. The city of Rome which became the wonder of the civilized world was not built in a day. Rome, the magnificent city, required many years and thousands of workers to construct it. The tremendous amount of resources, human labor, money and time were involved in erecting die city that became the envy of the world. In the same way, all great and brilliant works cannot be achieved in a day. Slow progress must not make us impatient. Every great work requires time and energy. A great work cannot be finished in a day. Patient labor is necessary for many years to finish it. Hence, patience combined with perseverance is the key to succeed in life.

There were things in the world which took a considerably long time to mature. It is the nature of a task that determines the length of time it would take to be accomplished. Some people are in the habit of getting impatient when a task takes a little longer than usual to complete. They do not understand or rather deliberately forget the nature of the task and start losing heart. This maxim is used to tell the impatient people that great works are not done/accomplished overnight or in haste. Such things require requisite time, patience and continuous effort. It is applicable not only in the case of studies but also in the case of success in life itself that one needs steady and continuous work.
